Segmented anti-blocking cleaning device with variable roll angle and control method thereof

Abstract

The invention provides a segmented anti-blocking cleaning device with variable roll angle and a control method thereof. The cleaning device comprises weighing sensors, a left sieve plate, a main sieveplate, a motor, cams, roller push rod combination structures, a right sieve plate and a controller. The left sieve plate and the right sieve plate are rotatable relative to the main sieve plate. Thetwo roller push rod combination structures are respectively disposed under the left sieve plate and the right sieve plate, and the two cams are respectively driven by one motor. Rollers under push rods are in contact with the cams through the arc surfaces. The left sieve plate and the right sieve plate are respectively provided with a weighing sensor connected with the controller, and the controller controls start and stop of the two motors according to detection data of the weighing sensors. By means of the cleaning device and the control method, a combined harvester can be effectively prevented from tilting left and right during the slope operation, so that the blockage of materials on one side of a sieve can be avoided. The screening efficiency and the screening effect are improved, andthe cleaning efficiency is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and particularly relates to a material cleaning device used in a combine harvester, which is a segmented anti-blocking cleaning device with a variable side inclination angle and a control method thereof. Background technique [0002] Cleaning is an important link in agricultural production. After the materials are harvested, the grains need to be separated from the mixture to obtain clean grains. When the combine harvester is working on a sloping field, due to the inclination of the working ground and other reasons, the combine harvester is tilted left and right, and it is easy to have too much material on the side of the cleaning screen, resulting in accumulation and blockage; It is also offset when it reaches the screen surface. The above two situations will lead to insufficient utilization of the screen surface and excessive burden on one side of the screen. When one of the above two si...
