[0002] Biological organic fertilizer refers to a kind of fertilizer that combines specific functional microorganisms with organic materials mainly sourced from animal and plant residues, which have been harmlessly treated and decomposed, and has the effects of both microbial fertilizers and organic fertilizers.

[0003] After retrieval, the Chinese patent publication number: CN221133136U discloses a screening and filtering device for biological organic fertilizers, including a base, a support structure, a filtering box, a feed hopper, an elastic connection structure, a screening structure, a vibration structure, a transparent glass door and a handle; the support structure is arranged at the four corners of the top of the base, the filtering box is arranged on the top of the support structure, the feed hopper is arranged on the top of the filtering box, the elastic connection structure is arranged on both sides of the inner wall of the filtering box, the screening structure is arranged between the elastic connection structures, the vibration structure is arranged on the top of the base, the transparent glass door is arranged on the front surface of the filtering box, and the handle is arranged on one side of the transparent glass door. The advantages of the utility model compared with the existing technology are as follows: the utility model can not only facilitate the replacement of sieves with different pore sizes according to people's needs, but also vibrate in the up and down direction and the left and right direction simultaneously during the screening process to improve the screening efficiency and avoid sieve blockage. Although this application can solve the problem that the filter plate, sieve and device of the existing screening and filtering device are integrated structures, which makes it inconvenient to replace filter plates and sieves with different pore sizes according to people's needs during use, reducing the application range and flexibility of the device, and when in use, the sieve can only vibrate back and forth left and right, and its vibration amplitude is relatively regular, and the movement trajectory of biological organic fertilizer particles on the sieve is relatively regular. When the mesh of a part of the sieve is blocked, the raw materials in this area are difficult to move to other positions for screening, resulting in easy blockage of the sieve. However, when the sieve vibrates, it will also cause the overall vibration of the device, which will not only generate noise but also shorten the overall service life of the device.
