CAM DEVICE OF GRAIN COMBINE HARVESTER FOR DYNAMIC ALIGNMENT OF LAYER OF GRAIN HEAP DURING CLEANING WHEN WORKING ON SLOPES Russian patent published in 2014 - IPC A01D41/12 A01D75/28 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural engineering. The grain combine harvester device for dynamic alignment of layer of grain heap on the cleaning sieve when working on slopes comprises an automatic tracking system of side rolls of the combine, the hydraulic motors, cams, compression springs and pushers. The cleaning sieve is attached to the sidewalls of the harvester thresher through suspensions. The tracking system of side rolls of the harvester comprises a pendulum connected with the lever to the rotary valve-throttle. The cams of the right and left rolls are made with the phase angle of rotation for providing the joint motion along the roll of the grain heap with the cleaning sieve and the phase angle of rotation for the motion of the sieve down the roll with relative sliding of the grain heap up the roll. Comparison of phase angles of rotation of the cams when moving the sieve up and down the roll is about 2.3:1.

EFFECT: use of invention provides an alignment of layer of grain heap on the width of the sieve and reduction of grain losses.
