[0002] The screening device is a device used for fine sorting of organic fertilizer, which is usually composed of a feeding system, a screening system, a discharging system, etc. Its working principle is to feed the organic fertilizer raw materials into the screening system through the feeding system, and then the organic fertilizer is divided into products of different particle sizes through screens with different apertures in the screening system, and finally the screened organic fertilizer products are output through the discharging system.

[0003] The traditional vibrating screening device mainly utilizes the vibration generated by a vibrating motor or an exciter to subject the organic fertilizer to vibration and impact force on the screen surface, so that particles smaller than the screen hole pass through the screen, while larger particles are retained on the screen surface, thereby achieving material screening. However, when the vibrating screening device is screening the organic fertilizer, the organic fertilizer may adhere to the screen due to its high humidity, causing clogging of the screen and affecting the normal use of the screening device. In addition, the vibrating screening device will also generate a lot of noise when working, affecting the health of the operator.
