In the utility model, a screening component is provided, the motor is turned on, and one end of the output shaft of the motor drives the power rod to rotate, and the power rod drives the vibrating screen block to rotate, and the vibrating screen block knocks on the screen to make it vibrate up and down quickly. When the screen moves upward, the screen drives the side plate to move, and the side plate squeezes the pressure plate. The pressure plate also squeezes the first spring to form a compressed state. When the vibrating screen block no longer knocks on the screen, the screen is reset due to the elastic force of the first spring. In this way, the powder is screened reciprocatingly. Through this design, the crushed powder is effectively screened, and there is no need for the staff to screen the powder before unloading, which greatly reduces the manual labor intensity of the staff, improves the work efficiency, and has a good use effect.
