Discharging-type powder and particle material unloading system

The invention discloses a discharging-type powder and particle material unloading system, and relates to the field of powder and particle material carrier vehicles. The discharging-type powder and particle material unloading system comprises a power takeoff connected with a chassis transmission of a motor tractor. The power takeoff is installed on an air compressor of a chassis longitudinal beam in a driving mode through a transmission shaft. The air compressor communicates with an air pipeline installed outside a tank body through an air inlet pipe. A discharging opening is formed in the bottom of the tank body and is further connected with a discharging pipeline. A pneumatic ball valve which is controlled by a controller to be opened is installed on the discharging pipeline. By means ofthe discharging-type powder and particle material unloading system, the problems that an existing bulk cement semitrailer is high in material remaining ratio and low in discharging speed, and the pipelines can be blocked easi
