Definitions
- the present disclosure relates to harvesting articulated (jointed) combines and more particularly to improved an improved feeder assembly having lateral tilt and carried by the forward tractor or crop processing power unit (hereinafter, “PPU”).
- PPU crop processing power unit
- the weight of the header is applied to the top outside portions of the feeder house front structure
- the weight is typically carried by either the top middle, or bottom middle of the structural rectangle where it is “pinned” to provide the pivot for the tilting of the load carrying front face adaptor of the feeder front face.
- this requires significant structural strength to provide a beam (top or bottom) that supports the heavy header in the middle, and then severely weakens the beam by cutting a hole in it to allow the pin hinge.
- the heavier the prospective load the larger the hinge pin must be, and so the beam gets deeper and deeper for structural strength in an area where that depth is a deterrent to good overall design practice.
- this disclosure proposes to solve the problem of unfortunate cylinder force vectors by applying the lift forces of the cylinders to the top-front area of the feeder instead of to the bottom front structures. Also, by anchoring the cylinders significantly forward (versus typical designs) of the front axle location, the net effect is to have lift cylinders that are significantly more vertical in their applied force to the feeder house structure. This also is a good configuration given that the heavy weight of the header is supported at the top of the front of the feeder in the “cradle” that engages the top beam of the header. Such cylinder lift configuration also could have use for swathers, forage harvesters, and other crop cutting assemblies carried on the front of a tractor.
- the disclosed feeder assembly will support the header and allow side-to-side oscillation (lateral tilt) by means of allowing a curved top surface on the front of the feeder to be saddled by a curved dome that sets down atop and around the curved top of the feeder front; thus, describing an arc of curvature as the dome is pushed to one side or another.

- feeder assembly 50 rollers and belts The direction of travel of feeder assembly 50 rollers and belts is in a direction such that harvested grain is located on the bottom of feeder assembly 50 .
- One of the unique properties of feeder assembly 50 is that it is pushed relatively far back into PPU 12 and closer to the concaves assembly than is seen in traditional harvesting combines.

Description
- This application claims benefit of provisional application Ser. No. 62/358,618 filed on Jul. 6, 2017; and is cross-referenced to applications Ser. No. 14/946,827 filed Nov. 20, 2015; Ser. No. 14/946,842 filed Nov. 20, 2015; and Ser. No. 14/967,691, filed on Dec. 14, 2015.
- Not applicable.
- The present disclosure relates to harvesting articulated (jointed) combines and more particularly to improved an improved feeder assembly having lateral tilt and carried by the forward tractor or crop processing power unit (hereinafter, “PPU”).
- As the typical commercial combine harvester gets ever larger, it is asked to lift wider and wider headers on its front via the feeder house. The increased weight of the headers with increased size can challenge the header lift, lateral tilt, and fore/aft mechanisms, as well as the feeder house structure in general. Aggravating these structures and applied force situations is the lift geometry of the hydraulic lift cylinders that typically are configured such that when pushing the feeder house upward they actually will apply a larger proportion of their force in a horizontal direction (horizontal force vector) versus the vertical component of the force (vertical force vector) that is causing vertical movement or lift of the feeder house.
- With respect to the side-to-side tilting mechanisms common to the industry and with reference to the feeder house lift condition explained above, while the weight of the header is applied to the top outside portions of the feeder house front structure, the weight is typically carried by either the top middle, or bottom middle of the structural rectangle where it is “pinned” to provide the pivot for the tilting of the load carrying front face adaptor of the feeder front face. As the feeder house gets wider, this requires significant structural strength to provide a beam (top or bottom) that supports the heavy header in the middle, and then severely weakens the beam by cutting a hole in it to allow the pin hinge. Of course, the heavier the prospective load, the larger the hinge pin must be, and so the beam gets deeper and deeper for structural strength in an area where that depth is a deterrent to good overall design practice.
- Accordingly, this disclosure proposes to solve the problem of unfortunate cylinder force vectors by applying the lift forces of the cylinders to the top-front area of the feeder instead of to the bottom front structures. Also, by anchoring the cylinders significantly forward (versus typical designs) of the front axle location, the net effect is to have lift cylinders that are significantly more vertical in their applied force to the feeder house structure. This also is a good configuration given that the heavy weight of the header is supported at the top of the front of the feeder in the “cradle” that engages the top beam of the header. Such cylinder lift configuration also could have use for swathers, forage harvesters, and other crop cutting assemblies carried on the front of a tractor. Concurrently, the disclosed feeder assembly will support the header and allow side-to-side oscillation (lateral tilt) by means of allowing a curved top surface on the front of the feeder to be saddled by a curved dome that sets down atop and around the curved top of the feeder front; thus, describing an arc of curvature as the dome is pushed to one side or another.

- One aspect of this disclosure, then, is a lifting assembly for a crop severing assembly forwardly carried by a tractor having a frame and an axle assembly carrying front wheel assemblies. The crop severing assembly has a forward end and a rear end. The disclosed lifting assembly includes a pair of bracket assemblies located at the forward end and atop the crop severing assembly. A pair of lift cylinder assemblies each has a lower end and a top end. The cylinder lower ends are located at either side of the rear end of the crop severing assembly and are attached to bottom brackets extending from the tractor frame forward of the tractor axle assembly. Each cylinder top end is attached to a trunnion carried by one of the crop severing bracket assembly for pivotally raising and lowering of the forward end of the crop severing assembly.
- Concurrently, this disclosure supports the header and allows side-to-side oscillation (lateral tilt) by means of allowing a curved top surface on the front of the feeder to be saddled by a curved dome that sets down atop and around the curved top of the feeder front; thus, describing an arc of curvature as the dome is pushed to one side or the other.
- Disclosed, then, is a feeder house assembly for accepting severed crop for processing by a harvesting combine having a front axle assembly and a frame. The feeder house assembly has a forward assembly at its forward end, a rear end, a lengthwise extent, a width, a top sheet, and a bottom sheet. The forward assembly supports a grainhead and has a front opening for receiving crop material severed by the grainhead and a rear opening at its rear end for passing severed crop material to within the harvesting combine for threshing of the severed crop material. A conveyor assembly extends from the front opening to the rear opening for moving severed crop material along the lengthwise extent between a counter-clockwise moving conveyor assembly and the bottom sheet. A pair of cylinders are attached at either side of the feeder house assembly at the top of the front of the feeder house and to bottom brackets extending from the harvesting combine frame forward of the harvesting combine axle assembly for pivotally raising and lowering of the forward end of the feeder house assembly.

- Referring initially to
FIGS. 1, 2, 3, and 4 , an articulated harvester, 10, consists of a forward powered PPU, 12, a rear grain cart, 14, and an articulation joint, 16, that connectsPPU 12 withrear grain cart 14. The details of articulation joint 16 are disclosed in commonly owned application Ser. No. 14/946,827 filed Nov. 20, 2015.PPU 12 carries a grainhead, 18, shown in a down harvesting position inFIG. 1 and in an up non-harvesting position inFIG. 3 , operator's cab, 20, grain cleaning and handling assembly, and engines.PPU 12 is devoid of any grain storage, such being exclusive inrear grain cart 14. While bothPPU 12 andrear grain cart 14 are shown being carried by wheel assemblies, one or both could be tracked. A screened air inlet, 15, is located atopPPU 12 where the air likely is the cleanest around harvestingcombine 10. - An off-loading auger assembly, 22, is in the folded home position and is carried by
rear grain cart 14.Grain cart 14 also supports a foldable roof, 24, shown in an open position, but which can fold inwardly to cover grain stored inrear grain cart 14.Foldable roof 24 may be made of metal, plastic, or other suitable material, but may be made of durable plastic for weight reduction and easy folding/unfolding. A grain storage bin, 28, is housed withingrain cart 14 and also may be made of plastic also in keeping with desirable weight reduction; although, it could be made of metal at the expense of weight. All plastic parts may be filled with particulate filled or fiber reinforced in conventional fashion and could be laminate in construction. Further details onrear grain cart 14 can be found commonly owned application Ser. No. 14/946,842 filed Nov. 20, 2015. - The operator is granted access to
cab 20 by a stair assembly, 30, that extends upwardly from just above the ground and will be more fully disclosed in commonly owned application serial number _____, filed _____ (U.S. 62/375,986, filed Aug. 17, 2016; attorney docket DIL 2-035). The skin or shell has been removed inFIG. 6 to reveal components housed withinPPU 12. A fan assembly, 32, is located centrally for air to enter through screenedair inlet 15. This location was chosen, as it arguably will be the cleanest flow of air aroundPPU 12. Radiators, as typified by a main cooling system air box, 34, surroundfan assembly 32 and are coolingly connected with a pair of engines, 36 and 38, located on either side of main coolingfan assembly 32.Engine 36 powers the hydraulics for articulatedcombine 10, whileengine 38 powers all other components of articulatedcombine 10. Exhaust after treatment assembly, 40, cleans air for emission control. When firing up the engines, which typically will be diesel engines,engine 38 is started first so that coolant flowing throughengine 38 will warm upengine 36 and the hydraulic fluid for articulatedcombine 10. The twin engines aspect will be described in detail in commonly owned application serial number _____, filed _____ (U.S. 62/358,629 filed Jul. 6, 2016; attorney docket DIL 2-040) and the airflow will be described in detail in commonly owned application serial number _____, filed _____ (U.S. 62/358,629 filed Jul. 6, 2016; attorney docket DIL 2-032). Other components visible inFIG. 6 will be described in detail in the referenced applications. - Grainhead 18 (see
FIGS. 1-3 ) typically will be between about 30 and 50 feet wide and severs the crop in various fashions from its stalk or its attachment to earth.Grainhead 18 is carried by a feeder assembly, 50, which conveys the severed crop consisting of both stalk and grain. By convention in the industry and herein, all material that is not grain is referred to as “Material Other than Grain” or, simply, “MOG”. - Progressing rearwardly and looking to
FIG. 7 , the crop material reaches the end offeeder assembly 50 at velocity and is projected rearwardly and upwardly onto the walls of a transition cone, which is a robust structure that describes shape and direction of material flow and generally funnels the flow of crop material toward both sides and the bottom of a rotor inlet. The remaining details of the concaves assembly will be found in commonly owned application Ser. No. 14/967,691, filed on Dec. 14, 2015.Feeder house assembly 50 is described in great detail in commonly owned application serial number _____, filed _____ (U.S. 62/358,618 filed Jul. 6, 2017; attorney docket DIL 2-029). - Returning to
FIG. 6 , a pulley assembly, 56, that includes a clutch and gearbox assembly, 58, is driven byengine 38 and provides power tofeeder assembly 50. A reverser motor, 59, is located adjacent to clutch andgearbox assembly 58 for reversingfeeder 50. Referring also toFIG. 8 , a shaft assembly (drive shaft and u-joints and a transfer case) is revealed in the interior ofPPU 12, and includes drive shafts, 60 a-60 d, and U-joints cases, 61 a-61 d, and a gearbox/transfer case, 62. Of course, the number of drive shafts and U-joints could be greater or less in number. Regardless, power tofeeder assembly 50 fromengine 38 is achieved in this fashion; although, other schemes and assemblies could provide power tofeeder assembly 50, as is appreciated by the skilled artisan. The drive shaft assemblies terminate atgearbox 62 from where power tofeeder house 50 is obtained and described later herein. - Referring now to
FIG. 7 , crop material severed bygrainhead 18 is conveyed upward and rearward byfeeder assembly 50, which consists of a rear roller assembly, 52, rockbeater roller assembly 54, and a front roller assembly, 55. In the embodiment in the drawings, 3 equally spaced-apart belts, 56 a, 56 b, and 56 c (seeFIGS. 8 and 16 also), fit over the 3 roller assemblies and carry transversely (transverse with reference to the direction of travel of harvesting combine 10) mounted flights, with a transverse flight, 64, being typical of such transverse flights, whose purpose includes to pull along the harvested grain material, which effectively forms a mat. The direction of travel offeeder assembly 50 rollers and belts is in a direction such that harvested grain is located on the bottom offeeder assembly 50. One of the unique properties offeeder assembly 50 is that it is pushed relatively far back intoPPU 12 and closer to the concaves assembly than is seen in traditional harvesting combines. Another uniqueness is that the rock beater assembly is pulled relatively forward of its traditional location, making it much easier to access for discharging accumulated rocks and debris, servicing, and repair. A rock beater roller assembly, 54, is located in front of the wheels ofPPU 12 and in a relatively open location. While 3 belts carrying cleats or slats, typified by a cleat, 57, (seeFIG. 16 ), that span laterally across the 3 belts are shown in the drawings, a current embodiment uses 4 such belts with a staggered pattern of cleats, each spanning between only 2 belts. It will be appreciated that the number of belts and pattern or cleats is a matter of design choice and not a limitation of the present disclosure. - Because harvesting combine 10 will be used in fields that undulate in both directions, grainhead 18 will need to be adjustable both side-to-side and heel-to-toe (forward and backward tilting) in order to keep on the ground for maximizing grain harvesting. This need translates into
feeder assembly 50 needs to tilt side-to-side and heel-to-toe, as indicated byarrows FIG. 11 . -
FIG. 8 reveals cylinder assemblies, 68 and 70 (seeFIG. 9 ), that provide the lift movement offeeder assembly 50 for raising and loweringgrainhead 18. Liftcylinder assembly 68 is pivotally attached at its bottom to a bracket assembly, 76, and liftcylinder assembly 70 is attached at its bottom to a bracket assembly, 78; and at their tops, respectively to bracket assemblies, 80 and 82.Bracket assemblies PPU 12, whilebracket assemblies feeder assembly 50 at its forward end.Bracket assemblies PPU 12, providing an anchor location to be closer to the front offeeder assembly 50. Sincebracket assemblies PPU 12, there is a more direct transfer of the lifting forces offeeder house assembly 50 fromcylinder assemblies 68/70 through frame 17 andPPU 12 wheel assemblies to the ground.Bracket assemblies feeder assembly 50, also making the top anchor location forcylinder assemblies 68/70 relatively close to the forward end offeeder assembly 50. Coincidentally and necessarily, such design requires the use trunnions, 81 and 83, to mountcylinder assemblies 68/70, wherebracket assemblies 80/82 carrytrunnions 81/83. Moreover,trunnions 81/83, respectively, are connected tocylinder assemblies 68/70 not at the cylinder ends, but are located some distance down on the cylinder tube, as can be seen in, for example,FIGS. 8 and 9 . Thus, the stroke length of thecylinder assemblies 68/70 can be much greater than the actual length of the cylinders compared anchoring the upper ends of the cylinders at their ends. The net of such design is thatcylinder assemblies 68/70 are oriented more vertically than conventional cylinder mounting designs. Such more nearly perpendicular cylinder mounting tofeeder assembly 50 and, therefore, the force exerted onfeeder assembly 50 bycylinder assemblies 68/70, has a much greater percentage of its linear force being used to vertically liftfeeder assembly 50, as opposed to pushingfeeder assembly 50 horizontally away fromPPU 12. - Referring additionally to
FIGS. 9 and 12 , pulley assemblies, 84, 86, and 88, are revealed with a belt, 90, fitting overpulley assemblies pulley assemblies pulley assemblies pulley assemblies Tension pulley assembly 96tensions belt 92 whilefeeder assembly 50 is taking in cut material or running in a feeding direction. Should feeder assembly become clogged, for example, the belts can be run in a reverse direction to clear the clog, as described above, usingreverse motor 59. While running in a reverse direction,tension pulley assembly 97tensions belt 92. - Of course roller assemblies span transversely across
feeder assembly 50 from each of the pulley assemblies, as described above. It should be noted thatpulley assembly 84 has two different sized pulleys for speed adjustment, as doespulley assembly 86. By relieving the tension onbelt 90, it can be moved between the two different sized pulleys, as described. A tension assembly, 98 (seeFIGS. 7 and 12 ), movesroller assembly 55 forward and backward to adjust the tension ofroller belts rear roller assembly 52 receives power frombelts roller belts - An alternative embodiment for the belt drive system is seen in
FIGS. 21 and 22 , which alternative belt drive system uses a single belt, 158. InFIG. 21 , the arrows indicate the direction of travel ofbelt 158 for feeding severed crop intofeeder assembly 50 betweenbottom sheet 113 and cleated/slatted belts 56.Belt 158 surmounts pulley assemblies, 160, 162, and 164. Idler rollers, 166 and 168, are used to ensure sufficient contact ofbelt 158 against the lower portion ofpulley assembly 162 for adequate rotation ofdrive roller 54.Pulley assemblies drive rollers rod 174 and levers 171/175, the tension pulley assemblies alternatively exert pressure onbelt 158 depending upon the direction of travel ofbelt 158. For example, as shown inFIG. 21 ,belt 158 is moving in the direction of the arrows, which causes severed crop to be fed intofeeder house assembly 50 andpulley assembly 172 to press againstbelt 158 andpulley assembly 170 is not press againstbelt 158. As shown inFIG. 21 ,belt 158 is moving in the direction of the arrows, which causes any severed crop insidefeeder house assembly 50 that might be causing a clog to be moved forward and out of feeder house assembly. In such unclog mode,pulley assembly 170 presses againstbelt 158 andpulley assembly 172 does not press againstbelt 158. - In
FIG. 11 , we also see a gear box platform, 100, forgearbox 62;tension assembly 98; a hook assembly, 102, forgrainhead 18; and pin holders, 104a and 104b, for lockinggrainhead 18 in position with pins (seeFIGS. 18 and 19 ). Additionally, we see the sheet metal in whichfeeder assembly 50 is housed, as illustrated by sheet metal pieces, 106, 108, and 110 (seeFIG. 12 ; bottom sheet (e.g. metal), 113,FIG. 16 ). Additionally, openings, 112A and 112B, provides access to rockbeater roller assembly 54, such as in case removal of an object is required. -
FIGS. 12, 13, 14, and 15 , show a front-end assembly, 114, that provides a variety of functions or capabilities forfeeder assembly 50, including, inter alia, side-to-side rotation ofgrainhead 18, heel-to-toe movement ofgrainhead 18, and retention/securing ofgrainhead 18 in position for grain harvesting. Front-end assembly 114 is composed of multiple components to be described below. - Tilting of front-
end assembly 114 and, thus,grainhead 18 is achieved by use of cylinder assemblies, 118 and 120 (FIGS. 13 and 14 ), which use tube assemblies, 122 and 124 (FIG. 13 ), as the pivot point for such tilting. As best seen fortube assembly 124, such assembly consists of two concentric tubes placed within an aperture with one of the tubes being fixed while the other tube is free to rotate. The apertures actually are in a both fixed support or frame, 126, and a moving support or frame, 128, as seen inFIG. 14 . The third major support of front-end assembly 114 is a frame, 130, which carriesgrainhead 18.Frames end frame assembly 114.Frame 128 a offrame 128 has an arched saddle or curved dome, 131, at its top, which is coated with a friction-reducing material, such as a high-density polyolefin, that nests on frame 138 b of arched ordomed top 133.Frames Frame 128 a is movable, whileframe 128 b is stationary. A pair of cylinders or linear actuators, 132 and 134, attached between frames 130 a and 130 b, so thatframe 128 a moves relative to frame 128 b. Frame 130 carriesgrainhead 18, which concurrently rotates side-to-side along withframe 128 a. Along with this rotation, the lower flat areas also move relative to each other, so a friction promoting material sheet, 136 (such as a high-density polyolefin, seeFIG. 14 ), is placed therebetween also. - With respect to the movement of
frames Cylinders 132/134 can be placed tangent to the arc of rotation, easing their power requirements. This is significant considering modern grain heads can be 50 feet (15+ meters) or more in length. - Looking now to
FIG. 16 , a joint assembly, 138, is connected togearbox assembly 62. A rotating shaft, 53, housed within a tube, 140, connectsgear 138 with pulley assembly 84 (seeFIG. 12 ). The components housed withinfeeder assembly 50 also are revealed inFIG. 16 . Rotatingshaft 53 receives power from the drive shaft assembly. Belts driverear roller 52 that power the feeder house conveyer assembly described herein. - In
FIGS. 17 and 18 , mid-mounted rockbeater roller assembly 54 is revealed in greater detail. Housed beneath such assembly is a reservoir, 66, usually formed from metal that accumulates rock and debris forced downwardly thereinto by rockbeater roller assembly 54, as described above. A cylinder assembly, 142, operable remotely by the operator is actable to open the reservoir to dump its contents, such as at the end or side of the field being harvested. The forward position of the mid-mountedrock beater assembly 54 permits such easy dumping of its contents. Moreover, should debris become lodged withinrock beater assembly 54, the operator can easily reach thereinto to remove such lodged rocks and debris. - As described in reference to
FIG. 13 ,grainhead 18 can be locked into position and unlocked usingpin holders FIGS. 19 and 20 show the locking mechanism therefor. In particular, the locking mechanism includes a linear actuator, 144, and a pair of elongate pins, 146 and 148.Linear actuator 144 is fixed at each end to one of thepins 146/148, but is otherwise unattached or free-floating. The other or free end ofpin 146 can extend throughpin holder 104 a, while the free end ofpin 148 can extend throughpin holder 104 b (not seen). A plate, 148 having an elongate slot is fixed to a bottom plate, 150, and is located adjacent to pin 146. A plate, 152, having an elongate slot is fixed to a bottom plate, 150, and is located adjacent to pin 148. Pin 146 carries a shorter pin, 154, that extends through the aperture inpin 148; whilepin 148 carries a shorter pin, 156, that extends through the aperture inplate 152. Such short pins and apertured plate pairs preventelongate pins 146/148 andlinear actuator 144 from rotating. Whenlinear actuator 144 is in an unextended or active state, elongate pins orrods 146/148 are in a retracted position so thatgrainhead 18 can pivot, as described above. However, whenlinear actuator 144 is in an extended or home state,elongate pins 146/148 extend throughpin holders 104 a/ 104 b and lockgrainhead 18. - While the device, assembly, and method have been described with reference to various embodiments, those skilled in the art will understand that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope and essence of the disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof.
