摘要:
The present invention concerns a self-aligning coupling structure for releasably connecting a rear end of a feeder assembly to a frame of an agricultural harvester such as a combine and the like. The self-aligning coupling structure includes a pair of releasable couplings laterally spaced from each other on opposite sides of the feeder assembly and combine frame. Each releasable coupling includes first and second apertured coupling elements. One of the apertured coupling elements is provided on and extends from the combine frame while the other apertured coupling element is provided on and extends from a housing of the feeder assembly. The coupling elements each have complementary guide surfaces provided thereon. When the feeder assembly is to be coupled to the combine frame, the guide surfaces on the respective coupling elements of each releasable coupling cooperate with each other to self-align both horizontally and vertically the apertures in the coupling elements relative to each other thereby facilitating the passage of a pivot pin through the aligned apertures so as to releasably connect the feeder assembly to the combine frame for pivotal movement about the axis of the pivot pins.

A foreign object detection and removal system for an agricultural combine is provided. The system includes a controller operatively connected to a feederhouse and a chopper assembly. The feederhouse includes an acoustic element for detecting foreign objects and an actuator for opening and closing a door of the feederhouse to remove foreign objection. The chopper assembly includes an actuator to retract a knife bank to allow for the passage of foreign objects through the chopper assembly without causing damage to the chopper assembly.

A safety stand is provided for minimizing the effect of hydraulic failure in an agricultural harvester. The safety stand has a series of notches along a longitudinal edge of the safety stand which are designed to accept and received a protrusion affixed to a cylinder of a hydraulic cylinder which raises and lowers a feeder arm. When the feeder arm is raised, the hydraulic cylinder is in the full upright position, the safety stand can be lowered such that the protrusion enters and is held within a notch to prevent accidental downward movement of the feeder arm. If the notch fails, or the safety stand is not properly engaged, the longitudinal edge of the safety arm is allowed to follow the protrusion, until a subsequent notch is reached, which then engages the protrusion, safely stopping the downward path of the feeder arm.

A rotary element and a rotary element balancing system of a combine harvester. The rotary element includes a rotary member that rotates during operation and one or more blade mount assemblies. The rotary element also includes one or more auto-balance assemblies mounted to the rotary member to compensate for a mass offset on the rotary element due to the one or more blade mount assemblies being dislodged or broken. The one or more auto-balance assemblies include one or more tracks and one or more spheres located inside the one or more tracks and in contact with first and second bearing race edges. Loads are transferred from at least one of the first bearing race edge and the second bearing race edge, when the rotary member rotates, to the one or more spheres that self-align within the track to compensate for the mass offset on the rotary element.

A rotary combine including a feeder mechanism and a rotor assembly having an impeller assembly arranged at a forward end of a rotor. The feeder mechanism includes a housing which is pivotally connected to the combine about a transverse axis. The feeder mechanism housing envelops a conveyor assembly used to impart linear movements to the crop materials as they are advanced toward the rotor assembly. Prior to their introduction to the rotor assembly, the linearly advancing crop materials are discharged from a rotary member. A salient feature of the present invention involves the communicative relationship established between the rearmost rotary member from which the crop materials are discharged and the foremost end of the impeller assembly. The longitudinal spacial relationship therebetween is such that the crop material flow is permitted to transmute from the linear flow imparted thereto as the materials moved toward the rotor assembly and a rotary or circulatory flow imparted thereto as the materials are introduced to the whirling blades of the impeller assembly.

A cleaning system for use in a combine harvester including an auger bed mounted within a frame such that when the combine harvester is laterally inclined from the horizontal, the cleaning system, including the auger bed and a sieve, may be leveled or substantially leveled to a generally horizontal position. The auger bed can include a plurality of augers located side by side with their axes positioned generally longitudinally in the combine harvester.

A combine feeding system includes a lower conveyor roller configured to rotate around a lower conveyor roller axis, an upper conveyor roller configured to rotate around an upper conveyor roller axis and a drive shaft configured to rotate around a drive shaft axis. The lower conveyor roller axis, upper conveyor roller axis and drive shaft axis are substantially perpendicular to first and second housing walls. The feeding system also includes at least one chain configured to move over the drive shaft, the lower conveyor roller and the upper conveyor roller. The feeding system further includes at least one lower support arm coupled to the drive shaft and the lower conveyor roller and configured to pivot about the drive shaft axis. At least one force mechanism is configured to apply a force to the at least one chain in at least one of a first direction and a second direction.

A combine threshing system includes a rotor having and in-feed area at a front end of the rotor and a rotor body configured to convey material along a helical path from the front end of the rotor body to a rear end of the rotor body. The system also includes a substantially cylindrical threshing chamber positioned circumferentially around and spaced apart from the rotor body. The threshing chamber includes a lower portion substantially concentric with the rotor body and having an inner surface positioned a first distance from an outer surface of the rotor body and an upper portion having a first inner surface substantially concentric with the rotor body and positioned the first distance from the outer surface and a second inner surface that is substantially concentric with the rotor body, positioned a second distance from the outer surface and is greater than the first distance.

A spreader assembly for a combine harvester is disclosed, the assembly including a pair of disks configured to be rotated such that chaff material dropped onto the disks is spread about the combine harvester, wherein each disk is operably connected to its own motor and a spreader frame assembly. The spreader frame assembly includes a first side support pivotably connected to a frame of the combine harvester, a second side support pivotably connected to the frame of the combine harvester, and at least one disk support configured to support at least one of the pair of disks. The spreader frame assembly further defines an opening configured such that when the combine harvester is windrowing material, no portion of the spreader frame assembly interferes with the flow of windrowing material.
