[0002] The grain conveyor uses an inclined conveyor belt to transport grain from a low place to a high place and then drop it into the transportation equipment. During use, in order to adapt to transportation equipment of different heights, the height of the conveyor belt needs to be adjusted. For this reason, most grain conveyors use a lifting conveyor belt. During the movement of the grain conveyor, the raised conveyor belt must be laid flat to prevent the fuselage from tilting and tipping over. Grain conveyors in the prior art mostly use a driving motor to drive a steel wire rope to pull the oblique support connecting rod, the oblique support connecting rod drives the bracket to rise and fall, and the bracket drives the conveyor belt to rise and fall. The lifting method of the steel wire rope driven by the driving motor has a slow lifting speed, the stroke length error of the steel wire rope is large during the winding process, and the lifting height of the conveyor belt is difficult to accurately control; during the movement, the steel wire rope shakes and is prone to disordered winding, which requires manual adjustment by the staff, increasing the difficulty of the workers' operation and affecting the work efficiency.
