Abstract

The invention provides a horizontal axial flow threshing device, its control method and a harvester, including a horizontal axial flow threshing drum, several radial balancing devices, axial balancing devices, a horizontal axial flow cover plate, a gravure screen, a displacement sensor and a controller ; The radial balance device is axially installed in the horizontal axial flow threshing drum, the axial balance device is arranged on the axial center line inside the horizontal axial flow threshing drum, and can drive the radial balance device to rotate around the axial balance device, The invention combines the working mode of the transverse axial flow threshing drum with the passive balance technology and the principle of electromagnetic induction. The threshing drum itself is in a relatively balanced and stable working state in real time due to the vibration generated by threshing, thereby reducing the damage of rice seeds during threshing and ensuring the quality and stability of rice seeds after threshing Well, strong reliability.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a transverse axial flow threshing device, a control method thereof and a harvester. Background technique [0002] The working environment of the combine harvester is harsh and the working conditions are complicated. When the threshing drum is working, the threshing drum itself is always in an unbalanced state due to the winding of the rice stalks and the falling of the grains during the threshing process. During the threshing process, the grains are gradually separated along the concave screen of the threshing drum, so that the damping between the threshing drum and the top cover is greater than the damping between the threshing drum and the concave screen, so that the radial vibration of the threshing drum exists when the upper and lower damping is different. At the same time, when the rice stalks move along the axial direction during the threshing pro...
