A 3D cleaning system with lateral vibration device and combine harvester

Abstract

The present application relates to the field of harvesting machines, in particular to a 3D cleaning system with a transverse vibration device and a combine harvester. Since the sensor directly detects the transverse amplitude value of the upper sieve box component, the error caused by detecting intermediate variables is avoided, and the accuracy and reliability of obtaining the transverse amplitude data are improved. The controller determines the difference between the transverse amplitude value and the theoretical amplitude value. In the case where the difference is greater than the preset value, the sensor controls the linear drive to drive the transverse vibration assembly to rotate. In this process, the telescopic end of the linear drive produces linear telescopic motion, thereby pushing the transverse vibration assembly connected thereto to rotate around the connection point, so that the transverse amplitude value is equal to the theoretical amplitude value. By adopting the closed-loop control mode to adjust the transverse amplitude value, the amplitude control precision of the transverse vibration assembly is improved, so that the material is more evenly distributed on the screen surface of the upper sieve box component, thereby enhancing the cleaning effect of the upper sieve box component.
