[0001] The utility model relates to the technical field of powder and particle material transport vehicles, in particular to an unloading auxiliary device of a powder and particle material transport semitrailer. Background Art

[0002] The discharge port of the traditional powder material transport semi-trailer is a simple straight pipe structure. Compressed air enters the fluid material pipe through the pipeline, passes through the pores of the fluid material pipe, and becomes a number of small airflows with a certain speed and impact force, which continuously impact the powder material particles. When the friction between the upward airflow and the powder material particles is greater than the gravity of the powder material particles themselves, the powder material in the entire pipe will be in a suspended state. At this time, the solid particles have the same properties as liquids and can flow under pressure to form fluid materials that are discharged through the discharge pipeline.

[0003] However, during the unloading operation of the existing powder and particle material transport trailer, when the powder is unloaded in large batches, the impact of the transported powder when falling may not only make the existing small blockage more serious, but may also directly cause the powder to be compacted at the outlet, forming a hard blockage, resulting in reduced unloading efficiency. Therefore, it is necessary to propose a new type of unloading auxiliary device for the powder and particle material transport trailer. Utility Model Content

[0007] Preferably, a feed pipe is connected through the central surface of the stabilizing plate, and a side end of the feed pipe is connected to a pneumatic conveying structure, and the feed pipe guides the powder and granular materials inside the semi-trailer through the pneumatic conveying structure.

[0008] Preferably, a mounting plate is fastened to the top of the connecting frame, a pneumatic drive structure is fastened to the top of the mounting plate, and a pneumatic piston rod is connected to the bottom output end of the pneumatic drive structure.

[0010] Preferably, the bottom of the pneumatic piston rod is tightly connected with a piston pressing plate, and the piston pressing plate is sealingly engaged and slidable inside the sleeve.

[0011] Preferably, the bottom end of the sleeve connected to the feed pipe is connected to a guide pipe, and the guide pipe extends to the inside of the sealed discharge groove.
