Description

Technical Field

[0001] This utility model relates to the field of unloading devices, specifically to a bottom unloading structure for a ash-loading semi-trailer. Background Technology

[0002] A semi-trailer is a trailer whose axle is located behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers and are heavy-duty transportation vehicles connected to the semi-trailer head by a towing pin. A ash-carrying semi-trailer is a semi-trailer used to transport powdery materials such as cement.

[0003] Chinese utility model patent CN210366084U discloses a bottom unloading structure for a ash-discharging semi-trailer. This structure includes a box body, with a support column fixedly mounted at the center of the top of the box body. One end of the support column is fixedly connected to an inlet pipe via a fixing bracket. An inlet port is fixedly installed at one end of the inlet pipe, and a high-pressure water gun is movably connected to the center of the inlet port via Velcro. A high-pressure water pump is fixedly installed inside the box body. The output flange of the high-pressure water pump is connected to a water inlet pipe, and the input flange of the high-pressure water pump is connected to a water guide pipe. One end of the water guide pipe passes through the box body and connects to the high-pressure water gun. However, the height of the inlet port of this bottom unloading device cannot be adjusted, making it difficult to seal with the semi-trailer's unloading port. This results in dust being emitted during the unloading of powdery materials, damaging the surrounding environment and affecting the health of workers.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem that the inlet height of the bottom unloading structure in the prior art cannot be adjusted, this utility model provides a bottom unloading structure for a ash-loading semi-trailer.
