Self-discharging semi-trailer with lifting loading and unloading platform

Abstract

This utility model discloses a self-unloading semi-trailer with a lifting loading and unloading platform, including a semi-trailer cargo box. A fixed cylinder is fixedly connected to the surface of the semi-trailer cargo box, and an adjusting plate is slidably connected to the inner wall of the fixed cylinder. Multiple unloading plates are fixedly connected to the surface of the adjusting plate, and multiple unloading holes are opened on the surface of the semi-trailer cargo box. Multiple sets of guide plates are fixedly connected to the inner bottom wall of the semi-trailer cargo box, and multiple cargo boxes are placed between a pair of guide plates. In this utility model, the adjusting plate slides upward under the action of a lead screw. When the height of the color sensor corresponds to the height of the color mark, the color sensor senses the color at the color mark position and, through an electrical signal, controls the output end of the multi-stage electric telescopic rod to drive the push plate to send the cargo box onto the unloading plate. At this time, the output end of the forward and reverse motor drives the lead screw to reverse, driving the adjusting plate and the unloading plate to descend as a whole. The advantage of this is that it realizes rapid and automatic lifting and unloading operations.
