After the fertilizer enters the screening device together, the large fertilizer particles in the fertilizer cannot pass through the filter plate and are accumulated on the filter plate. The filtration efficiency of small fertilizer particles will be blocked by the large fertilizer particles, thereby affecting its screening efficiency. Utility Model Content

[0009] Wherein, a lower discharge port and an upper discharge port are respectively provided on the outer box body and the support plate, and a docking plate matching the second filter plate is fixedly connected to the top of the outer box body.

[0010] The beneficial effect of the utility model is that small particles in the fertilizer are screened by the second filter plate, and then the push plate and the baffle plate can be driven to rotate by the rotating ring during rotation, so that the fertilizer is moved to the top of the first filter plate, so that large particles in the fertilizer can be limited on the third filter plate, and small particles can return to the second filter plate again, so that when the device screens large and small particles of fertilizer, the screening efficiency of small particles of fertilizer can be increased, and it is avoided that large particles are always blocked and cannot be discharged, which affects the rapid separation of small particles of fertilizer.

[0018] In this embodiment: the bottom plate 1 is a carrier of the bearing device, the installation groove 11 opened at the top of the bottom plate 1 is used to install the fixed rod 12, and the support rod 15 slidably connected to one side of the fixed rod 12 is used to support the outer box body 2, and the fixed rod 12 and the support rod 15 are slid in the inner wall of the installation groove 11, so that the bottom of the bottom plate 1 can be installed on the vibrating screen, and the device as a whole is vibrated, so that the device can increase the screening speed of the biological fertilizer by vibration. The annular grooves 21 opened at both ends of the outer box body 2 are used to install the rotating ring 24, so that the rotating ring 24 rotates on the inner wall of the annular groove 21, and the support plate 22 rotatably connected to the inner wall of the rotating ring 24 can move the first filter plate 3 The third filter plate 32 is supported and fixed, and the second filter plate 31 is supported and fixed on the inner wall of the outer box body 2, and is located on the outer side of the third filter plate 32. The filter holes of the first filter plate 3 are relatively large, so that all kinds of fertilizers can pass through the first filter plate 3 and enter the second filter plate 31, while the third filter plate 32 and the second filter plate 31 can only allow the fertilizer particles that meet the standards to pass through, so that the fertilizer particles that meet the standards enter between the second filter plate 31 and the outer box body 2, and the fertilizers are screened and stored. When the fertilizers are screened, the fertilizers can be added between the third filter plate 32 and the second filter plate 31, and the particles that meet the standards in the fertilizers can pass through the second filter plate 31 and enter through the vibration. The fertilizer particles are then pushed into the inner wall of the outer box 2 to separate the large and small particles. When the large particles are being screened, they are still in the second filter plate 31, which will affect the efficiency of the small particles directly passing through the second filter plate 31 and entering the outer box 2, thereby hindering the rapid screening of the fertilizer particles. At this time, the rotating ring 24 can be controlled to rotate, and one end of the push plate 25 fixedly connected between the rotating rings 24 fits with the inner wall of the second filter plate 31, so that the fertilizer can be pushed to move between the second filter plate 31 and the third filter plate 32, so that the fertilizer can be pushed through the second filter plate 31. At the same time, when the push plate 25 supports the fertilizer particles to the top position of the second filter plate 31, the baffle 26 Under the protection of the filter plate 3, the fertilizer particles are pushed to above the height of the first filter plate 3, at which time the fertilizer can fall on the first filter plate 3, and the large-particle fertilizer and the small-particle fertilizer can enter the third filter plate 32. At this time, some of the fertilizer that has not passed through the first filter plate 3 can be vibrated again to enter between the third filter plate 32 and the second filter plate 31, so that some large-particle fertilizer can be limited in the third filter plate 32 and directly separated from the small-particle fertilizer. Therefore, when the device is screening large and small particles of fertilizer, it can increase the screening efficiency of small-particle fertilizer, avoid large particles being blocked and unable to be discharged, and accumulation affects the small-particle fertilizer passing through the second filter plate 31 and being directly received by the outer box 2.

[0019] Two side blocks 13 are fixedly connected to one side of the two fixed rods 12, and a limiting rod 14 is fixedly connected between the side blocks 13, and an inner spring 141 is sleeved on the outer wall of the limiting rod 14; the two side blocks 13 fixedly connected on one side of the fixed rod 12 are used to install and fix the limiting rod 14, so that the limiting rod 14 can pass through the bottom of the support rod 15 to limit it, so that the fixed rod 12 and the support rod 15 are integrated, and the support rod 15 can slide at the same time, so that when the bottom plate 1 is vibrated, the support rod 15 can increase the vibration effect of the outer box body 2 under the support of the inner spring 141, so that it slides left and right, and at the same time, the fixed rod 12 is supported by the outer spring 121, so that the outer box body 2 can slide back and forth, so that the fertilizer is in the device for rapid displacement, thereby improving the screening efficiency.

[0020] An outer spring 121 is fixedly connected between the fixing rod 12 and the mounting groove 11, and the outer box body 2 and the support plate 22 are connected via a fixing block 23; the fixing rod 12 is supported by the outer spring 121, so that the outer box body 2 can slide back and forth, the fixing block 23 is fixedly connected to the outer box body 2 and the support plate 22, and the fixing block 23 is slidably connected to the rotating ring 24, so that the support plate 22 can fix the support of the first filter plate 3 and the second filter plate 31 without affecting the rotation of the rotating ring 24.

[0021] A limiting groove 221 is provided at the connection between the support plate 22 and the rotating ring 24, and a limiting ring 241 matching the limiting groove 221 is fixedly connected to the inner wall of the rotating ring 24; the limiting groove 221 is used to limit the limiting ring 241 fixedly connected to the inner wall of the rotating ring 24, so that the rotating ring 24 can rotate on the inner wall of the annular groove 21 while the rotating ring 24 will not be separated from the outer box body 2.

[0022] A lower discharge port 27 and an upper discharge port 28 are respectively provided on the outer box body 2 and the support plate 22, and a docking plate 311 matching the second filter plate 31 is fixedly connected to the top of the outer box body 2; the lower discharge port 27 and the upper discharge port 28 are respectively used to remove the small-particle fertilizer and the large-particle fertilizer after screening, and the docking plate 311 fixedly connected to the top of the outer box body 2 is used to cover both sides of the second filter plate 31 to prevent the pushed fertilizer from leaking out.

[0023] The working principle and use process of the utility model are as follows: when screening fertilizers, the staff puts the fertilizers between the third filter plate 32 and the second filter plate 31. When the device vibrates, the qualified particles in the fertilizers can pass through the second filter plate 31 and enter the inner wall of the outer box body 2, so that the large and small particles are separated. Then, by controlling the rotation of the rotating ring 24, the push plate 25 pushes the fertilizer to move, and the fertilizer is pushed above the first filter plate 3. At this time, the fertilizer can fall on the first filter plate 3, and the large and small particles of fertilizer can enter the third filter plate 32. At this time, some of the fertilizers that have not passed through the first filter plate 3 can be vibrated again to enter between the third filter plate 32 and the second filter plate 31, so that some of the large particles of fertilizer can be limited in the third filter plate 32 and directly separated from the small particles of fertilizer. Therefore, when the device is screening the fertilizer particles, it can increase the screening efficiency of the small particles of fertilizer, avoid the large particles being blocked and unable to be discharged, and the accumulation affects the small particles of fertilizer to pass through the second filter plate 31 and be directly received by the outer box body 2.
