るものである。The above-mentioned prior art has the following problems. Since the purpose of the grader device is to cut and correct the snow-covered road surface, it is appropriate to mount the grader device in accordance with the position of the center of gravity of the snow removal vehicle. However, a change in weight due to an increase or a decrease in the amount of the anti-skid material filled in the anti-skid material tank provided in the snow-plow vehicle greatly affects the axial load of the snow-plow vehicle. Therefore, in the road surface adjustment work of the grader device, the lateral deflection of the snow-removing vehicle due to the imbalance of the front and rear wheel loads is extremely dangerous to other passing vehicles. Furthermore, since the road surface after the road surface adjustment by the grader device becomes a mirror surface state due to friction between the cutting edge and the snow-covered road surface, it becomes very slippery,
It is of great concern to passing vehicles and pedestrians. The present invention has been made in view of such problems of the related art, and the purpose thereof is to:
It seeks to provide: 1. The counterweight is movable so as to prevent an imbalance in the weight on the axle of the snow removal vehicle due to a change in weight due to an increase or decrease in the amount of the anti-slip material in the anti-slip material tank and the amount of replenishment. 2. Equipped with a sensor for detecting the remaining amount of anti-slip material in the lower center of the anti-slip material tank, always detects the amount of anti-slip material in the anti-slip material tank during operation, and detects the operation of each gate on both sides of the lower part of the anti-slip material tank. An opening position detection sensor is attached, the input signal is received by each automatic control device, and based on this signal, taking into account the type of anti-skid material, calculating the moving distance of the counterweight,
By outputting an appropriate command signal to the hydraulic actuator via the hydraulic control unit and moving the counterweight, the axle of the snow removal vehicle can maintain an appropriate load.
