Definitions
- the present disclosure relates to a system and method to unload grain from a grain tank on an agricultural harvester to a transport vehicle, and specifically to the use of a diagonally-disposed drag auger and gravity sump for more evenly unloading grain from the grain tank.
- the presently disclosed articulated combine is based on obtaining more even grain outflow from the grain bin, provision for a side-discharge chaff spreader assembly, a unique unloading arm assembly, and additional features disclosed herein.
- a forward grainhead carried by a forward bogey devoid of grain storage and operated by an operator and a rear grain storage bogey.
- the rear bogey carries a grain unload arm.
- a diagonal grain auger assembly is disposed within the rear bogey and transfers grain from at least the front area of the rear bogey into the grain unload arm.
- a grain unload arm assembly is carried by the rear bogey and is composed of a moveable upper grain unload arm and a fixed lower grain unload arm whose proximal end is at a corner of the rear bogey, not at the center which lowers the angle, and which is connected by a slew bearing assembly matable to a rack for rotating.
- a grain unload auger is disposed within each of the upper grain unload arm and a lower grain unload arm.
- the moveable upper unload arm assembly is lifted from a storage position and rotates via the slew bearing assembly to mate with the lower fixed grain unload arm assembly.
- FIG. 1 is an overhead view of the disclosed articulated harvester and a grain hauling semi vehicle with the rear harvester bogey crabbed for unloading grain into the grain hauling semi vehicle and showing the proximity sensors and cameras carried by the disclosed harvester;
- FIG. 2 is a rear view of the disclosed harvester and a grain hauling semi vehicle of Fig. 1 ;

- the articulated agricultural harvester or combine (these terms being synonymous and used interchangeably) in the drawings is a TribineTM harvester (Tribine Industries LLC, Logansport, IN) having a grain bin capacity of 1 ,000 bushels of clean grain and unloads the clean grain at a rate of 500 bushels per minute.
- TribineTM harvester Tribine Industries LLC, Logansport, IN
- Normal grain removal from an elevated grain bin uses an unload auger running from the back to the front of the grain bin for transferring grain to the unload arm assembly.
- grain preferentially is removed from the rear of the grain bin; thus, leaving the remaining grain in the front of the grain bin.
- This can cause weight on the tongue (articulation joint) to increase from near zero to around 8,600 lbs.
- the disclosed diagonal drag auger evens out grain removal so that the grain is removed fairly uniformly from the front as well as the rear of the grain bin; thus, not placing any significant increase on the tongue.
- an articulated harvester, combine, or harvesting combine, 10 is fitted with a 16-row cornhead, 12, and consists of a forward bogey, 14, and rear bogey, 16. While combine 10 is fitted with wheels, it could be a tracked combine.
- Forward bogey 14 is fitted with an operator cab, engine, grain cleaning and handling, and similar capability, but for grain storage, which it is devoid of.
- rear bogey 16 is fitted with a grain bin and unloading capability, for example, a grain-unloading arm, 18, housing a conveyor (e.g., a screw conveyor), such as is described in commonly-owned U.S. Patent No. 8,286,984.
- Adjacent to combine 10 is a grain hauling vehicle, 20, consisting of a forward cab with engine, 22, towing a grain trailer, 24, capable of holding 1 ,000 bushels of clean grain.
- a grain hauling vehicle consisting of a forward cab with engine, 22, towing a grain trailer, 24, capable of holding 1 ,000 bushels of clean grain.
- Such vehicle also could be a grain cart, gravity wagon, or other grain storage vehicle.
- combine 10 unloads its clean grain from rear bogey 16 while the combine is in the field harvesting grain; thus, the need to unload its grain bin very rapidly.
- vehicle 20 is parked next to combine 10 and combine 10 moves over adjacent to semi vehicle 20.
- Rear bogey 16 then can be crabbed to move its unloading arm 18 to a position such that the discharge end, 26, is centered over grain trailer 24 and clean grain unloading proceeds. Since the combine operator needs to steer combine 10 while simultaneously pulling over close to vehicle 20 and crabbing rear bogey 16, anything to aid the combine operator in knowing precisely where forward bogey 14 and rear bogey 16 are relative to grain hauling semi vehicle 20 would be greatly appreciated by the combine operator.
- forward bogey 14 is fitting with cameras, 28, on its unload left side and optionally on its right side.
- Rear bogey 14 also is fitted with camera, 32, at its upper front center looking into the grain storage bin. Each of these cameras feeds a video image to the combine operator so he can see grain hauling semi vehicle disclosed harvester and a grain-hauling vehicle 20.
- Rear bogey 16 also is fitted with a proximity sensor, 34, at its left rear.
- Discharge end 26 of grain unloading arm 18 also is fitted with a camera, 38.
- An additional camera, 39 is carried by rear bogey 16 at its upper rear.
- cornhead 12 is fitted with a proximity sensor, 40 at its left side. All proximity sensors also feed their data to the combine operator.
- the cameras may be Agcam cameras (Dakota Micro, Inc., Cayuga, ND) and the sensors may be Senix TSPC-155 ultrasonic distance sensors (Senix Corporation, Hinesburg, VT).
- Harvesting combine 10 unloads clean grain only on its left side in the embodiment in the drawings.
- the cameras and sensors could be located only on the right side for unloading clean grain on the right side or located on both sides for providing unloading of clean grain on both sides.
- the use of such proximity sensors and cameras is disclosed in commonly-owned application identified by Attorney Docket No. DIL2015PC, filed on even date herewith.
- unloading arm is seen to consist of a moveable upper section, 18A, and a fixed lower section, 18B, connected by a slew bearing assembly, 44, seen in an exploded view in Fig. 4 wherein bellows, 49, has been removed.
- the slew bearings rotate against a rack assembly, 47, when unloading arm 18A is raised by a cylinder assembly, 46 (see Fig. 2), with rotation of upper unload arm 18A powered by a rotation hydraulic motor, 49 (see Fig. 5).
- upper unload arm 18A must be both lifted up and rotated to mate with lower unload arm 18B.
- Slew bearings, collectively, 51 rotate against rack assembly 47 when upper unload arm 18A rotates after being lifted into position.
- the upper end of fixed lower unloading arm 18B is fixed at an upper corner of rear bogey 16.
- Moveable upper unload arm assembly 18A is lifted from a storage position and rotates via slew bearing assembly 44 to mate with the lower fixed grain unload arm assembly 18B.
- An auger, 48 (Fig. 4), disposed in upper unloading arm 18A has a bearing, 50, at its lower end that seats against a bearing, 52, disposed at the upper end of an auger, 68 (see Fig. 14), inside lower unloading arm 18B.
- power supplied by motor 54 (see Fig. 2), to the unseen auger in lower unloading arm 18B transfers its rotation to auger 48 in upper unloading arm 18A for unloading of grain.
- Figs. 5 and 6 show unload arm 18 is an extended position for unloading of grain from rear bogey 16 in which harvested grain is stored.
- Chaff spreaders, 56A and 56B receive chaff from forward bogey 14 and distribute the chaff sideways from the direction of travel of harvesting combine 10.
- Wheels, 58A and 58B are turned to the side, as rear bogey 14 is in a crabbed position for unloading of grain (see Fig. 1 ).
- a tongue, 57 is connected to an articulation joint assembly, not specifically seen in the drawings.
- Articulation cylinders, 60 and 62 are part of the articulation joint assembly, as more fully described in the commonly-owned patents cited above.
- Figs. 9 and 10 show rear bogey 16 with unload arm assembly 18 in a stowed position.
- FIG. 7 and 8 rear bogey 16 is seen from above to reveal diagonal grain movement auger assembly with a fixed upper cover or hogback, 64, in position in Fig. 7 and removed in Fig. 8 to reveal diagonal drag auger, 66.
- Hogback 64 covers the top and upper sides of diagonal drag auger 66; thus, permitting grain to enter diagonal drag auger 66 at the lower side areas.
- Diagonal auger 66 draws grain from the front of rear bogey 16 to even out grain removal both front and back.
- the front pitch of diagonal auger 66 is closer together and the pitch opens up or widens towards the rear. The close pitch will only hold so much grain.
- rear bogey 16 grain removal system consists of the sump auger that draws grain from the rear are of the grain bin and diagonal drag auger 66 that draws grain from the front area of the grain bin; thus, resulting in even grain removal from the grain bin carried by rear bogey 16.
- a framework assembly, 68 supports auger 66, as seen in Figs. 1 1 and 12.
