AQUILA DAVID MAST ( 54) IMPROVEMENTS IN OR RELATING TO AGRICULTURAL MACHINES ( 71) We, SPERRY CORPORATION formerly SPERRY RAND CORPORATION, a Corporation organised and existing under the laws of the State of Delaware, United States of America, of 1290 Avenue of the Americas, New York, New York 10019, United States of America, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to mobile agricultural machines convertible between field operating and transport modes The invention is also concerned with a method of converting a mobile agricultural machine between field operating and transport modes.
A crop material processing or harvesting machine, such as a forage harvester, combine or windrower commonly utilises a crop delivery means, such as a crop material pick-up, which is mounted on the front of the machine and extends laterally beyond one or both sides of the machine in order that a swath of crop material substantially wider than the machine, may be gathered by the means from the field The use of this type of pick-up presents difficulties when it is desired to transport such a machine along public roads, over narrow bridges or through narrow field gates between harvesting operations.
In an attempt to overcome this problem.
several methods have been employed to convert the delivery means from a field operating mode wherein the machine has a predetermined width to a transport mode wherein the width of the machine is less than the predetermined width.
One known method is to pivot the delivery means to the machine so that the means can be folded from a field operating mode wherein the means extend transversely to > the direction of forward travel of the machine to a transport mode wherein the delivery means extend along the side of the machine parallel to the direction of travel, such as disclosed in U S Patent Specification Nos 193 ( O 855 and 1,972,783.
Another known method is disclosed in U.S Patent Specification No 3,683,605 wherein the delivery means, a combine header, is releasably coupled to the front of “ne combine in a field operating mode in which an axis of elongation of the header is transverse to the direction of forward travel of the combine The header is provided with a set of wheels mounted on each end thereof such that the header may be towed behind the combine in a transport mode having its axis generally parallel to the direction of combine travel.
Yet another known method is pivotally to mount the delivery means, extending laterally beyond one side of the machine in the field operating mode such that it may be pivoted upwardly about its pivotal axis.
towards the machine in a transport mode.
One example of such a converting means is disclosed in our U S Patent Specification
No 3 936 994.
The present invention provides yet another method and means for converting the machine and is an improvement over the prior art in that it provides a simpler construction and more durable arrangement.
According to one aspect of the invention there is provided a mobile agricultural machine adapted to be moved forwardly across a field and comprising a crop processing means and crop delivery means operable, in use, to deliver crop material to the crop processing means and being movable in relation to the crop processing means to convert the machine between field operating and transport modes, the machine further comprising first coupling means extending forwardly from the crop processing m 0 o 1 568 783 means, and second coupling means extending rearwardly from the crop processing means, the delivery means including means adapted to register with the first and second coupling means respectively to facilitate coupling of the delivery means forwardly of the crop processing means for conversion of the machine to the field operating mode, and rearwardly of the crop processing means for conversion of the machine to the transport mode, the register means including an opening defined in a rear wall portion of the delivery means adapted to receive separately the first and second coupling means.
According to another aspect of the invention there is provided a method of converting an agricultural machine adapted for movement in a normal direction of forward travel and which comprises means for processing crop material and means for delivering crop material to the processing means, between a field operating mode wherein the machine has a predetermined width and a transport mode wherein the machine has a width less than the predetermined width, comprising the steps of:
(a) coupling the delivery means to a front portion of the processing means by inserting a first support member projecting forwardly from the processing means into registry with an opening defined in a rear wall portion of the delivery means for converting the machine to its field operating mode; (b) uncoupling the delivery means from the processing means by disengaging the first support member from the opening defined in the rear wall portion of the delivery means:
(c) relocating the delivery means from its field operating mode location wherein the rear portion of the delivery means is adjacent the front portion of the processing means to a transport mode location wherein the rear portion of the delivery means is adjacent a rear portion of the processing means; and (d) coupling the delivery means to the rear portion of the crop processing means by inserting a second support member projecting rearwardly from the crop processing means into registry with the opening defined in the rear wall portion of the delivery means to convert the machine to its transport mode.
A forage harvester according to the invention will now be described, by way of example, with reference to the accompanying drawings in which:Figure 1 is a plan view of the forage harvester, mounted on a tractor wherein a windrow pick-up, shown in solid lines is disposed adjacent the right-hand wheel of the tractor in a field operating mode and as shown in broken lines, is disposed rearwardly of the tractor in a transport mode.
Figure 2 is a side elevation of the forage harvester of Figure 1, showing the windrow pick-up in solid lines in the field operating mode and in broken lines in the transport mode.
Figure 3 is an enlarged rear view of the windrow pick-up taken on the line 3-3 of Figure 2, Figure 4 is an enlarged side elevation of a movable subframe of the harvester, the subframe being shown in solid lines, in a lowered coupling position and in broken lines in a raised storage position, and Figure 5 is an enlarged view of the subframe as seen on the line 5-5 of Figure 4.
the subframe again being shown in solid lines in the lowered coupling position and in broken lines in the raised storage position.
In the following description reference to right-hand’ and ‘left-hand’ relate to an observer standing at the rear of the machine and facing in the direction of normal forward travel of the machine.
Referring now to the drawings, and particularly to Figure 1 the forage harvester, generally indicated by the numeral 10 is mounted on the rear end of a tractor T having a pair of rear tractor wheels W.
However, the invention is not specifically limited to forage harvesters but may be applied to other mobile agricultural machines such as combines, mowerconditioners or windrowers.
The forage harvester 10 has a transverse hitch beam 11 which is connected by suitable mounting components to the 3-point hitch of the tractor T a projecting end of the transverse hitch beam 11 supporting crop processing means generally indicated by the numeral 12, beside the right-hand wheel W of the tractor T.
The major operational components of the crop processing means 12 are enclosed in a crop chopping chamber 19 defined by a front wall 13 having a crop material receiving opening 14 for the rearward passage of crop material (i e from right to left in Figure 1) into a pair of transverselyextending, counter-rotating, front feed rolls 16 located within the chamber 19 adjacent the receiving opening 14 The front feed rolls 15, 16 receive the crop material and move it rearwardly to a pair of transversely-extending counter-rotating, rear feed rolls 17 18 which feed the crop material to a cutter mechanism 20 which chops the crop material into small pieces.
The cutter mechanism 20 discharges the chopped crop material through a transition member (not shown) into a discharge spout 21 for ultimate delivery to a truck or trailing wagon (not shown) Since the operational components of the forage harvester 10 are 3 1 568 783 3 well known, they are not described in detail herein.
Crop material is delivered from the field to the crop processing means 12 by delivery means, constituted by the windrow pick-up 22 Other types of delivery means could also be readily used.
The windrow pick-up 22 includes a housing defined by an outer sidewall 23, an inner sidewall 24 and a rear wal 25 Rotatably mounted between the forward ends of the outer and inner sidewalls 23, 24 is a pick-up component 26 which picks up the crop from the field and directs it rearwardly and upwardly to a rotating auger 27 transversely mounted between the rear portions of the sidewalls 23 and 24 The auger 27 receives the crop material from the complete length of the pick-up component 26 and feeds the material towards the left along the rear wall of the housing to a discharge opening 28 formed in the left-hand end of the rear wall Retractable fingers 31 suitably mounted within and projecting from the cylinder 30 of the auger 27 feed the laterally moving crop material through the discharge opening 28 and thence through the aligned opening 14 of the processing chamber 19 The crop material then passes to the front feed rolls 15, 16 as previously described.
Power for driving the operational components of the pick-up 22 and the crop processing means 12 is supplied by the power take-off shaft of the tractor The power take-off shaft is connected to a gearbox (not shown) mounted on the transverse hitch beam 11 near the rear end of the processing chamber 19 by a power transmission shaft (not shown) extending generally parallel to and below the transverse hitch am 11.
On the outer right-hand side of the processing chamber 19 are exposed suitable sprockets (not shown) fixed to respective shafts of the front and rear feed rolls 15, 16 and the cutter mechanism 20, these sprockets being drivingly coupled by a chain to a drive sprocket (not shown) on an output shaft (not shown) of the gearbox.
On the inner left-hand side of the forage harvester 10 are exposed suitable arrangements of chains and sprockets (not shown) for coupling shafts of the pick-up 22, the auger 27, and the mechanism of retractable feed fingers and pulley and sheaves (not shown) for drivingly coupling another output shaft (not shown) of the gearbox to the chain and sprockets through a drive shaft (not shown) of the delivery means.
In the field operating mode, the pick-up
22 is supported in a generally horizontal plane forwardly of the crop processing means 12 and has its major axis of elongation disposed transverse to the direction of travel of the harvester 10, as shown in solid lines in Figures 1 and 2 The left-hand sidewall 24 of the pick-up 22 is disposed a predetermined distance outwardly from the right-hand wheel W of the tractor T and the right-hand sidewall 23 is disposed outwardly of the right-hand side of the crop processing means 12.
The structure for releasably coupling the pick-up 22 on the forward end of the crop processing means 12 is shown in Figures 1, 2 and 3 As shown in Figure 3 a pair of laterally spaced inclined bars 32 are secured to the outer surface of the rear wall 25 adjacent the outer and inner edges of the discharge openings 28 of the pick-up 22.
Adjacent the top edge of the discharge opening 28 and spanning the upper end portions of the bars 32 is a cross-bar 33.
Near the centre of its length, each bar 32 is provided with an aligning hole 34 and a latching hole 35 is formed near the lower end of the bar 32.
The pick-up 22 is provided with a ground engaging wheel 36 rotatably mounted by an axle 37 which extends between respective lower apices of a pair of laterally spaced, generally V-shaped, support plates 38 attached to the rear wall 25.
A hooked-shaped support member 40, best seen in Figures 1 and 2 is mounted on the front wall of the crop processing chamber 19 the member 40 extending adjacent the upper edge of the opening 14 The support member 40 extends generally outwardly and upwardly and is of a transverse width suitable to be received within the discharge opening 28 defined in the rear wall 25 of the pick-up 22 On each of the two edges of the opening 14 of the crop processing chamber 19 is a corresponding angle iron 41 having one flange coplanar with the plane of the opening 14 and the other flange attached to the corresponding sidewall of the chamber 19, Midway on each of the angle irons 41 is an aligning peg 42 that projects outwardly and is of a diameter that fits within the respective aligning hole 34 provided in the corresponding bar 32 of the pick-up 22 Disposed below each aligning peg 42 is a corresponding latching hole 43 which is aligned with the respective latching hole 35 when the pick-up 22 is in the position shown in full lines in Figures 1 and 2.
The coupling or attaching operation is a very simple procedure The windrow pickup 22 is moved and oriented to its position forwardly of the processing means 12 and adjacent the tractor T The attachment 22 is raised and tilted forward towards the front wall of the processing chamber 19 so as to guide the discharge opening 28 over the hooked-shaped support member 40 which then extends into the discharge opening 28 and embraces the top cross-bar 33 As the 1 568 783 1 568 783 pick-up 22 is lowered, the cross-bar 33 slides into wedging relationship with the support member 40 The interengagement of the aligning pegs 42 with the respective aligning holes 34 provides proper alignment of the pick-up 22 on the processing means 12 and thereby ensures proper communication of the discharge opening 28 with the receiving opening 14 of the processing means 12 To prevent the pick-up 22 from separating from the processing means 12 as the harvester 10 is moved across the field in the field operating mode, bolts 44 are passed through the aligned latching holes 35 43 of the pick-up 22 and the processing means 12.
Thus, the pick-up 22 is releasably coupled to the forward end of the processing means 12 in the field operating mode by the engagement of the hook-shaped support member 40 and the discharge opening 28.
Proper alignment and orientation of the pick-up 22 on the processing means 12 is obtained by the aligning pegs 42 and aligning holes 34 Further, the pick-up 22 is secured in its field operating mode by the bolts 44 Although the greater part of the weight of the pick-up 22 is supported by the hook-shaped member 40 part of the weight is taken by the ground-engaging wheel 36 whose primary function is to guide the pick-up 22 over ground irregularities.
The means for converting the forage harvester 10 from its field operating mode.
shown in solid lines in Figures l and 2 to its transport mode, shown in broken lines in Figures 1 and 2 comprise coupling means.
generally designated by the numeral 45 The coupling means 45 enable the pick-up 22 to be detachably mounted rearwardlv of the crop processing means 12, on the transverse hitch beam 11 with the major axis of the pick-up 22 transverse to the direction of forward travel of the machine such that the overall width of the forage harvester 10 in its transport mode is less than the width of the forage harvester 10 in its field operating mode.
The coupling means 45 include a subframe 46 (best shown in Figure 4 and 5) and mounting means in the form of two spaced plates 47 for mounting the subframe 46 on the right-hand side of the transverse hitch beam 11 inwardly of the crop processing means 12 and rearwardly of the tractor T.
The subframe 46 includes a main body portion in the form of two spaces angle bars 48 a top lateral brace 50 interconnecting the upper ends of the bars 48 (considering the subframe 46 in the position shown in full lines in Figures 4 and 5) and a cross brace 51 spanning the midpoints of the bars 48 The subframe 46 further includes a pair of elongated side plates 52 which are respectively secured to ends of the angle bars 48 in the angular disposition shown in Figure 4.
The other end of each side plate 52 extends along the outer side of the respective mounting plate 47 and is pivotally connected thereto by a suitable fastening device, such as a pin 53 so that the subframe 46 can be moved relative to the transverse hitch beam 11 between a raised storage position and a lowered coupling position Diagonal braces 54 extending between the midsection of the angle bars 48 adjacent the cross brace 51, and the rear section of the mounting plates 47 are provided to add rigidity to the subframe 46 The corners of the side plates 52 nearest to the hitch beam 11 are shaped to conform to the outer profile of the transverse hitch beam 11 as shown in Figure 4.
The subframe 46 is pivotable about the mounting pin 53 between a lowered coupling position shown in solid lines in Figures 4 and 5 to a raised storage position.
shown in broken lines To maintain the subframe 46 in either the raised or lowered position a U-shaped bracket 55 supporting a spring-engaging fastening pin 56 is secured to the right-hand side plate 52 The fastening pin 56 has a handle portion 57 and a plunger portion 58 which extends through a hole 60 in the side plate 52 The right-hand mounting plate 47 is provided with first and second holes 61 62 into which the pin 56 extends in the raised and lowered positions, respectively A spring 63 is coiled about the plunger portion 58 between the bracket 55 and a washer 64 secured to the plunger portion 58 adjacent the side plate 52.
To move the subframe 46 from its raised storage position, the fastening pin 56 is pulled outwardly from left to right in Figure 5, thereby withdrawing the plunger portion 58 of the pin 56 from the hole 61 and the subframe 46 is lowered to its coupling position The spring 63 now under compression urges the plunger portion 58 inwardlv to seat within the hole 62 in the mounting plate Thus, the subframe 46 is maintained in its lowered coupling position by the fastening pin 56 and is prevented from further downward movement by the abutting engagement of the corners of the side plates 52 and the transverse beam hitch 11.
The coupling means 45 further include a coupling support hook 65 which is similar to the support member 40 of the processing means 12 and which extends generally outwardly and upwardly from the top fateral brace 50 of the main body portion of the subframe 46 The coupling support hook 65 is adapted to be received within the discharge opening 28 o the pick-up 22 for supporting the latter rearwardlv of the processing means 12 in a transport mode.
Aligning means are provided in the form of a pair of aligning pegs 66 each of which is 1 568 783 secured to and projects outwardly from a respective end of the cross brace 51 The aligning pegs 66 are so positioned on the cross brace 51 as to be received by the aligning holes 34 when the machine 10 is in the transport mode in which the inner sidewall 24 is disposed inwardly from the outer sidewall of the processing means 12.
Latching holes 67 are also provided near the lower ends of the angle bars 48 to coincide with the latching holes 35 on the pick-up 22 when the pick-up is coupled to the subframe 46.
The pick-up 22, in the transport mode shown in broken lines in Figures 1 and 2, is coupled to the subframe 46 by the interengagement of the coupling hook 65 around the cross-brace 33 The aligning pegs 66 extend into the complementary aligning holes 34, and bolts 68 are passed through the cooperating latching holes 35, 67 Most of the weight of the pick-up 22 is supported by the coupling hook 65; however, part of the weight is taken by the ground engaging wheel 36.
Converting the forage harvester 10 from the field operating mode, wherein the forage harvester is of a predetermined width.
to a transport mode, wherein the forage harvester is of a width less than the predetermined width, is a very simple operation.
When the forage harvester 10 is in the field operating mode, the pick-up 22 is attached forwardly of the processing means 12 and is disposed a predetermined distance outwardly from the right-hand wheel W of the tractor T The width of the harvester 10 is effectively the transverse distance between the outer sidewall 23 of the pick-up 22 and the extreme left portion of the tractor T which ordinarily would be the left-hand rear tractor wheel W In this mode, the subframe 46 is normally carried in its raised storage position.
To uncouple or detach the pick-up 22 from the processing means 12, the bolts 44, are first released The pick-up 22 is then raised upwardly to slide the cross-bar 33 out of engagement with the hook support member 40 Instead of raising the pick-up 22 for the disengagement of the hook support member 40 and the cross-bar 33, the transverse hitch beam 11 and thus the processing means 12 may be lowered by the hydraulics of the tractor T through the 3-point hitch arrangement.
Once uncoupled, the pick-up 22 is moved to its transport location rearwardly of the tractor in a coupling relationship with the subframe 46 In the relocating step the operator either pulls or pushes the pick-up 22 on the ground engaging wheel 36 to the rear of the processing means 12 The pickup 22 is then rotated 180 degrees such that the discharge opening 28 faces the coupling hook 65 of the subframe 46 Changing the orientation of the pick-up 22 through 180 degrees from its field operating location can either be done prior to the relocating step or after it has been moved to its transport location Further, it is apparent that instead of moving the pick-up 22 around to the rear of the harvester, one could just as well reverse the orientation of the harvester.
Prior to coupling the pick-up 22 to the subframe 46, the subframe must first be lowered to its coupling position if it is in the raised storage position To lower the subframe 46 from the raised storage position to the lowered coupling position, the fastening pin 56 is pulled outwardly, the subframe is lowered and the fastening pin 56 is released whereby the coil spring 63 forces the plunger portion 58 thereof into engagement with the hole 62 The subframe 46 is now secured in its lowered coupling position by the fastening pin 56 and by the abutting engagement of the lower rearward corners of the side plates 52 with the top edge portion of the tranverse hitch beam 11.
Now, in the transport location, the pickup 22 is tilted forward towards the subframe 46 and raised slightly upwardly to guide the discharge opening 28 over the coupling hook 65 The aligning pegs 66 are located in the corresponding aligning holes 34 whereby the pick-up 22 is properly positioned on the subframe 46 and then the bolts 68 are passed through the matching latching holes 35, 67 to secure the pick-up 22 on the subframe 46.
Thus, in the transport mode, the pick-up 22 is disposed rearwardly of the processing means 12 partially supported on the ground engaging wheel 36 and has its major axis still transverse to the direction of forward travel of the machine Further, the inner sidewall 24 of the pick-up 22 is disposed inwardly from the outer sidewall of the processing means 12 thereby substantially decreasing the width of the machine in the transport mode.
