Abstract

The utility model disclose a pitch-variable self-dumping device for a motor dumping car, which comprises a frame assembly, a carriage, an oil cylinder, at least two pitch varying plates arranged in a symmetric manner, and an auxiliary device. The mounting shaft of the oil cylinder and the turnover shaft of the carriage are arranged on the frame assembly. The telescopic rod of the oil cylinder is arranged on the carriage. A pitch varying sliding chute is arranged on the pitch varying plate which is arranged on the turnover shaft by the pitch varying sliding chute. The axial line of the pitch varying sliding chute is parallel to the contact surface between the carriage and the frame assembly. With the utility model, a distance from a certain point on the carriage to the turnover shaft can relatively be varied before self-dumping of the carriage and the loaded good so that the carriage, the loaded good and gravity centers thereof relatively move backwards before self-dumping and power consumption are relatively scattered, energy consumption is relatively reduced, and self-dumping is relatively carried out more easily when the oil cylinder acts to lift the carriage and the loaded good to carry out self-dumping. The utility model can perform backward movement, self-dumping, descending, forward movement and returning of the carriage by using a same oily cylinder and has the advantages of simple structure, safety, reliability, low cost and good effect.
