A mechanism for manually and automatically adjusting the front support drum of an endless conveyor within the feederhouse of an agricultural combine. The front drum is rotatably affixed to the remote end of a pivot arm that is pivotably affixed to the side sheet of the feederhouse. The relative position of the drum to the floor of the feederhouse is manually adjustable by manipulation of a cam that moves the pivot arm toward and away from the floor to preset positions. In combination with the adjustment mechanism, is a pivot mounting for the pivot arm that allows the drum to move upwardly and rearwardly when a bulk or lump of crop material enters the opening between the drum and the floor, thereby preventing damage to the components of the feederhouse.

Front drum adjustment mechanism for a feederhouse on an agricultural combine

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.

Stone roll mount plate for a feederhouse on an agricultural combine

The apparatus is an improvement to a feederhouse on an agricultural combine. The apparatus has a first acoustic array having a first sounding board and acoustic sensor positioned beneath the front drum and feederhouse floor. There is 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 raise and the door rotates into contact with the latch.
