Abstract

This application relates to a road paving material feeding device for road construction, comprising: a feeding shell, wherein multiple feeding shafts are equidistantly rotatably arranged in the lower part of the inner cavity of the feeding shell, and a spiral feeding impeller is provided on the outer side of each feeding shaft; a first transmission mechanism is sleeved on the outer side of the feeding shaft. The device provided in this application embodiment enables uniform material feeding, resulting in better road paving levelness. Furthermore, the spiral feeding impellers prevent material from clogging the feeding port. When feeding is completed or needs to be stopped midway, two screw blocks merge together. Then, the transmission motor is started in reverse, driving the second transmission gear to rotate, which in turn drives the transmission screw to rotate. This causes the transmission screw to drive the screw blocks to move the baffle plate to the right until the baffle plate seals the feeding port. Then, the transmission motor is stopped, thus stopping the feeding, making the opening and closing of the feeding port more convenient.
