The invention belongs to the technical field of material level detection, and particularly relates to a sliding way with a sliding cover plate. The sliding way is an annular sliding way and is coaxially arranged on the lower end of a stock bin, the two sides of the stock bin are each provided with a stand column, the lower ends of the stand columns are in sliding connection to the sliding way, thesliding cover plate is arranged on the sliding way, side face sliding wheels are arranged on the contact faces of the sliding cover plate and the two side walls of the sliding ways, annular teeth arearranged on the inner side of the contact face of the upper surface of the sliding way and the sliding way cover plate, the annular teeth are engaged with a gear, the gear is connected with a slidingmotor, a top sliding groove is formed in the outer side of the contact face of the upper surface of the sliding way and the sliding way cover plate, a top sliding wheel is arranged in the top slidinggroove, a sliding motor drives the engaged gear to rotate, the sliding cover plate drives the stand columns to rotate, setting of a charge level indicator in the circumferential direction of the stock bin can be achieved, the top sliding wheel bears longitudinal pressure, friction resistance is reduced, the two side sliding wheels slide in sliding grooves in the side face of the sliding way, shaking is avoided, and meanwhile, friction force is reduced.
