Automatic height adjusting device for root cutter of sugarcane machine

The utility model provides an automatic height adjusting device for a root cutter of a sugarcane machine, which relates to the field of agricultural machinery and comprises a cross beam, a fixing plate, an angle sensor, a connecting shaft, two clamping plates, a rotating wheel and a controller. The rotation angle of the clamping plate is measured through the angle sensor to obtain the fluctuation condition of the ground, and the root cutting device is lifted through the controller, so that the problem that perennial roots are damaged due to the fact that a root cutter cannot be automatically adjusted during harvesting operation of a sugarcane harvester in the prior art is solved, the height of the root cutter can be adjusted in real time according to the fluctuation of the ground, and the service life of the root cutter is prolonged. And the survival rate of perennial roots is improved. 本实用新型提供了一种甘蔗机切根刀高度自动调节装置，涉及农业机械领域，包括横梁、固定板、角度传感器、连接轴、两块夹板、转轮和控制器。通过角度传感器测算夹板转动的角度得出地面的起伏状况，并通过控制器升降切根装置，解决了现有技术中甘蔗收获机在收获作业时，
