[0050] As shown in the embodiment, the crushing and screening device for fermentation processing of organic nutrient soil comprises a rack 1, a crushing assembly 2 for crushing the nutrient soil into small particles is arranged on the rack 1, and a screening assembly 3 for screening the crushed nutrient soil particles is arranged below the crushing assembly 2; wherein the screening assembly 3 comprises a screening shell 304, a frame 301 is rotatably arranged in the screening shell 304, a sieve plate one 302 and a sieve plate two 303 are arranged on the frame 301, and the sieve surface of the sieve plate one 302 is higher than that of the sieve plate two 303. Figure 2 Figure 3 ​As shown, on the basis of the first embodiment, in order to enable the frame 301 to rotate on the rack 1, one end (close to the first screen plate 302) of the frame 301 is rotatably connected to the side wall of the screening shell 304, and the other end (close to the second screen plate 303) of the frame 301 is rotatably connected to the driving member 4 to reciprocatingly rotate up and down.

[0051] The driving member 4 comprises a rotating rod 401 rotatably connected to the screening shell 304 by a motor 402; the two ends of the rotating rod 401 are respectively provided with an eccentric shaft 403; the two eccentric shafts 403 are rotatably connected with a connecting rod 404, and the lower ends of the two connecting rods 404 penetrate through the screening shell 304 and are rotatably connected to the two sides of the frame 301.

[0052] When the motor 402 drives the rotating rod 401 to rotate, the eccentric shaft 403 rotates around the axis of the rotating rod 401, and in the process of rotation of the eccentric shaft 403, the connecting rod 404 drives the frame 301 to reciprocatingly rotate up and down.

[0053] The end of the first screen plate 302 away from the second screen plate 303 is higher than or equal to the end of the first screen plate 302 close to the second screen plate 303, and the end of the second screen plate 303 close to the first screen plate 302 is higher than or equal to the end of the second screen plate 303 away from the first screen plate 302.

[0056] Working process:

[0057] The nutrient soil is first sent into the crushing assembly 2 and forms fine particles after crushing. These particles then fall on the first screen plate 302 of the screening assembly 3. The first screen plate 302 performs primary screening on the particles, and the qualified particles fall into the lower collecting box 1 5 through the screen holes. At the same time, the larger or un-screened particles are moved along the first screen plate 302 to the second screen plate 303 under the action of the rotation of the frame 301. When the particles fall from the first screen plate 302 to the second screen plate 303, the particles are naturally scattered due to the impact force of the drop, increasing the uniformity and effectiveness of the screening. The second screen plate 303 performs secondary screening on these particles, further separating out the qualified particles, which continue to fall into the collecting box 1 5 through the screen holes. The unqualified larger particles fall into the collecting box 2 6 from one end of the second screen plate 303, and the particles in the collecting box 2 6 are further processed. During the entire screening process, the frame 301 reciprocatingly rotates up and down under the action of the driving member 4, ensuring the sufficient screening and effective conveying of the nutrient soil particles.
