項記載の装置。[Scope of Claim for Utility Model Registration] 1. A removal plate having a lower end in contact with the floor of the loading platform and extending from the lower end above the loading platform and over the entire width of the loading platform, and a loading platform with the removal plate standing approximately upright from the loading platform. A device for removing earth and sand from a loading platform, comprising a removal plate moving mechanism that moves the removal plate back and forth along the road, and a hydraulic circuit that operates the mechanism. 2. The device according to item 1, wherein the lower end of the removal plate includes an extension plate portion extending along the floor surface. 3. The removal plate moving mechanism has a pair of wheels connected to the left and right side edges of the lower end of the removal plate and provided at the front and rear ends of the platform under the floor of the platform. The first chain is connected to the side edge of the removal plate a predetermined distance above the lower end of the removal plate, and is provided at a position corresponding to the front and rear ends of the cargo platform and above the floor surface of the cargo platform by the predetermined length. second
2. The device according to claim 1, comprising: a pair of second chains extending over a pair of wheels; and driving means for interlocking and driving the first chain and the second chain. 4. The hydraulic circuit is a hydraulic pump, a hydraulic motor rotated by pressure oil from the hydraulic pump, and is provided between the hydraulic pump and the hydraulic motor and controls the operation and stopping of the hydraulic motor and the direction of rotation during operation. 2. The apparatus of claim 1, further comprising a directional valve for switching, and wherein the hydraulic motor is coupled to the removal plate moving mechanism. 5. A power rotor balance valve is provided in the oil supply pipe between the hydraulic motor and the directional control valve so as to compensate for the case where the speed of backward movement of the removal plate is too fast.
Apparatus described in section.
