[0021] Embodiment 1, by Figure 1-3The utility model relates to a screening device for fertilizer production, comprising a box body 1, a hopper 2 is fixedly connected to the top of the box body 1, a material pipe 3 is fixedly connected to the bottom of the box body 1, a screening unit 4 is arranged inside the box body 1, a shell 5 and a channel 6 are also fixedly connected inside the box body 1, the inside of the shell 5 is communicated with the inside of the hopper 2 through the channel 6, an end of the channel 6 close to the shell 5 is higher than an end of the channel 6 far from the shell 5, a transfer member 7 is arranged inside the shell 5, and a crushing member 8 is arranged inside the channel 6;

[0022] In this design, the raw materials are poured into the screening unit 4 in the box body 1 through the hopper 2, and screened through the screening unit 4. The raw materials with smaller particles pass through the screening unit 4 and are discharged from the material pipe 3. The raw materials with larger particles remain on the surface of the screening unit 4 and enter the interior of the shell 5 as the screening proceeds. The raw materials with larger particles are transferred to the interior of the channel 6 through the transfer member 7, and the raw materials with larger particles are crushed by the crushing member 8 in the channel 6. The crushed raw materials enter the interior of the hopper 2 for further screening, thereby achieving a full screening and crushing process for the raw materials and ensuring the particle size quality of the raw materials.

[0023] The screening unit 4 includes a plurality of supports 401, each of which is fixedly connected to an elastic member 402, each of which is fixedly connected to a screening net 403, an eccentric roller 404 rotatably connected to the box body 1 is provided below the screening net 403, and one end of the eccentric roller 404 is fixedly connected to an output shaft of a driving motor fixedly provided on the box body 1;

[0024] The eccentric roller 404 is rotatably connected to the cylinder 405, and the cylinder 405 is in contact with the screening net 403;

[0025] This design makes it easy to drive the eccentric roller 404 to rotate through a driving motor. The eccentric roller 404 drives the cylinder 405 to continuously squeeze the screening net 403. With the use of the elastic member 402, the screening net 403 can be continuously vibrated to facilitate screening of raw materials. The elastic member 402 can be a spring, etc., and the cylinder 405 can reduce the wear between the eccentric roller 404 and the screening net 403.

[0026] An end of the screening net 403 away from the housing 5 is higher than an end of the screening net 403 close to the housing 5;

[0027] Such a design can make it easier for the raw material to move toward the shell 5 during the vibration process.

[0028] The screening unit 4 further includes a transmission member 9, and the eccentric roller 404, the transfer member 7 and the crushing member 8 are connected to each other through the transmission member 9;

[0030] The transfer member 7 includes a rotating shaft 701 connected to the housing 5 for relative rotation, and a scraper 702 is evenly fixedly connected to the rotating shaft 701, wherein the housing 5 is a side opening structure;

[0031] This design facilitates the scraper 702 to rotate through the rotating shaft 701, and the scraper 702 cooperates with the shell 5 to realize the transfer process of the raw materials.

[0032] The crushing member 8 includes a crushing shaft connected to the channel 6 for relative rotation;

[0033] This design makes it easy to crush the raw materials again through the crushing blades on the crushing shaft to ensure that the particle size of the raw materials is within a suitable range.
