METHOD OF DYNAMIC LEVELLING OF HEAP LAYER WHILE CLEANING GRAIN COMBINE HARVESTER AT WORK ON SLOPES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC A01F12/44 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to agriculture. At work on slopes of a grain combine harvester the cleaner shoe is communicated with the additional lateral oscillations. At the lateral oscillations the joint movement of the heap and the sieve during their movement up the heeling is provided. When movement of the sieve down the heeling the relative sliding of the heap up the sieve is provided. The device for dynamic levelling of heap layer while cleaning grain combine harvester comprises the sidewalls for suspension of sieves, the balancers of the sieve boot, the sieve and the pendulum of the gyroscope. The lateral oscillations are provided to the sieve boot at work on slopes by the vibrators of the right and left heeling, made in the form of a hydraulic cylinder with a rod and having rollers. The sieve boot interacts with spring shock absorbers through the guides. The volumes of the rod and the piston hydraulic cylinder cavities are made in the ratio of 1:2.3.

EFFECT: use of the group of inventions increases the efficiency of grain cleaning at work of the harvester on slopes by levelling the heap layer across the width of the sieve.
