Abstract

The invention provides an automatic balancing device for a threshing cylinder of a combine harvester and a control method. The automatic balancing device comprises an annular outer shell, a plurality of balance weight sliding blocks, an annular guide rail, an annular inner shell, permanent magnets and a dynamic balance detection system, wherein the annular inner shell is located in the annular outer shell, the annular guide rail is installed between the annular outer shell and the annular inner shell, the balance weight sliding blocks are distributed in the circumferential direction of the annular guide rail, and each balance weight sliding block is provided with an electromagnetic solenoid; the permanent magnets are circumferentially and uniformly arranged on the inner wall of the inner shell; the dynamic balance detection system comprises a detection mechanism and a controller; the detection mechanism is used for measuring vibration signals of a threshing cylinder shaft and the rotating speed of the threshing cylinder; and the controller calculates the unbalance amount of the threshing cylinder, the unbalance amount comprises the phase and the needed balance weight, the current of the electromagnetic solenoids is controlled through wires according to the phase and the result of the needed balance weight, and therefore the balance weight sliding blocks are controlled to move on the annular guide rail, online active dynamic balance adjustment of the threshing cylinder of the combine harvester is achieved, and the threshing effect and the working efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an automatic balancing device and a control method for a threshing cylinder of a combine harvester. Background technique [0002] The rotor is widely used in agricultural machinery, and the unbalanced problem of the rotor aggravates the vibration and noise of the whole machine, which leads to the reduction of working effect, frequent machine failures, and shortened working life of the machine. The threshing drum is the main working part of the combine harvester for threshing and separation. It is usually balanced on a dynamic balancing machine before assembly, but since the dynamic balancing machine cannot ensure that the supporting state is exactly the same as that of the machine, and the boundary conditions of the rotor change after assembly, at the same time It is also affected by the transmission components, so a new imbalance will be generated when...
