Abstract: A cleaning system of a header for an agricultural vehicle. The header includes a frame with a floor having at least one cutout therein. The cleaning system includes at least one door, an elongated member operably connected to the at least one door, and at least one actuator connected to the elongated member. The elongated member is rotatable by the at least one actuator to slide the at least one door between a first position for covering the at least one cutout and a second position for at least partially uncovering the at least one cutout and allowing an unwanted material to pass through the at least one cutout.

Abstract: An intake feeder system having a stone separator mounted between a crop elevator and the mouth of a threshing mechanism disposed longitudinally in a combine harvester. The stone separator includes a rotary feed beater and a sump disposed beneath the feed beater. The feed beater serves to advance crop raised by the elevator along a crop flow path towards the mouth of the threshing mechanism and to propel stones in the crop into the sump. A duct is provided in parallel with the crop flow path for connecting a space above the rotary feed beater to the mouth of the threshing mechanism.

Abstract: A combine harvester, has a device for separating out foreign objects, a feed rake with at least one tension mechanism, which is located in a channel and is redirected via at least one upper and one lower tension mechanism guide, at least one foreign-object capture basin, foreign object separating elements that extend through the tension mechanism and assigned to at least the upper tension mechanism guide, the foreign object capture basin is located in the engagement region of the foreign object separating elements.

Abstract: A rock trap disposed in a feeder adapter of a combine directly behind a sickle bar of a combine header and in an area in front of a rearwardly directed conveyor located for receiving cut crop from transversely directed conveyor of the header. The rock trap has a trap door which can be selectively opened so as to drop beneath the header rocks collected therein.

Abstract: An agricultural combine feeder assembly and rotor interface wherein the feeder assembly includes front and rear housing section connected by a pivot. The front section contains a conveyor while the rear section contains a rotating beater. The rearmost extremity of the beater is spaced from 5 to 16 inches from the forwardmost extremity of the impeller blade or blades on the front end of the rotor.

Abstract: A feederhouse on an agricultural combine include a pivoting faceplate between the header and feederhouse. The pivoting faceplate position indicia to assist an operator in properly positioning the faceplate. A front drum adjustment mechanism, which use a cam with cam position indicia to properly position the front drum. A stone roll mount plate permitting the proper adjustment of the stone roll relative to the feederhouse floor. A stone roll position indicia and a pointer to help position the stone roll.

Abstract: A feederhouse on an agricultural combine. Having a first acoustic array having a first sounding board and acoustic sensor positioned beneath the front drum and feederhouse floor. A second acoustic array positioned behind the front drum and between the conveyor chain encircling the front and rear drums. The second acoustic array also has a second acoustic sensor and second sounding plate. The acoustic sensor detects the impact of a stone on the sounding plates. A signal is transmitted via a controller from the sensor to a solenoid controlling a stone trap door latch. When the door opens, a sled also rotates into contact with conveyor chain. This deflects any crop flow containing stones. To close the door, the feederhouse is raised and the door rotates into contact with the latch.

Abstract: A rock guard for a crop harvesting combine header. The guard is attached to the grain table immediately behind the cutter bar and extends vertically upward from the grain table such that the upper edge is spaced below the resilient fingers of the reel when they move over the guard. Gaps formed in the guard register with the joints of the flexible grain table so that the guard will flex with the grain table. Brackets used to mount the guard to the grain table are secured by the exiting cutter bar bolts so that no special mounting holes are needed.

Abstract: 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.

Abstract: A stone trap assembly for inhibiting stones, rocks, and the like from passing into a combine threshing area from a feeder mechanism adapted to advance crop material through a housing. The stone trap assembly includes a stone receiving trough and a rotatable beater mechanism arranged in combination relative to each other. The stone trough and beater mechanism conjunctively extend laterally across the width of the feeder mechanism. The feeder mechanism includes a series of spiral flight sections, with each flight section having a helix configuration between opposite ends thereof to enhance performance of the feeder mechanism by lessening cyclic contact of the beater mechanism with the crop material passing therethrough and providing a generally uniform flow of crop material to the threshing area of the combine.
