A powder material receiving device includes a feeding device, a transfer cylinder, an adjustment assembly, a receiving plate mounted on the adjustment assembly, a first connecting pipe connecting the transfer cylinder and the feeding device, a second connecting pipe connecting the transfer cylinder and the receiving plate, a support base located below the receiving plate, a transfer tank, a pulse gas generator, and an air pump. The transfer cylinder is equipped with a nozzle and a valve interface. The transfer tank includes a tank body and a breather filter for internal pressure regulation. After receiving the material, before the receiving plate detaches from the transfer tank, the external pulse gas generator injects high-pressure pulse gas into the transfer cylinder through the nozzle. After the pulse gas stops, the external air pump extracts the powder-containing gas from the transfer cylinder, the first connecting pipe, the second connecting pipe, and the space above the tank body through the valve interface. This powder material receiving device effectively improves the working environment, reduces the health hazards to workers during powder material transfer, and increases transfer efficiency, thereby increasing the economic efficiency of enterprises.
