[0002] When planting crops, chemical fertilizers are applied at the same time in order to increase crop yields. However, long-term use of chemical fertilizers will cause the soil to become compacted, making it difficult to plant crops again. In order to avoid this problem, the use of active fertilizers is becoming more and more widespread.

[0003] Active biofertilizer converts garbage and sludge into biofertilizer through bacteria and microorganisms, but there are large stones and some difficult-to-decompose objects in the sludge and garbage, so they need to be screened.

After the motor 10 is started, its output end drives the rotating rod 11 to rotate, so that the rotating rod 12 rotates accordingly, so that the fixed block 21 and the stirring rod also rotate together to stir the fertilizer. At the same time, when the rotating rod 11 rotates, the bevel gear 16 rotates, driving the bevel gear 2 17 and the fixed shaft 18 to rotate together. When the fixed shaft 18 rotates, the elliptical wheel 19 rotates. When the elliptical wheel 19 rotates, its side wall squeezes the fixed plate 15, so that the fixed plate 15 moves up and down, thereby driving the rotating rod 2 12 to move up and down, so that the screening net 4 moves up and down together with the fixed ring 3, and the fertilizer on the screening net 4 is lifted up. The lifting and falling of the fertilizer can speed up the screening, and at the same time, it is prevented that stones and other debris are gathered on the surface of the screening net 4, so that the screening speed is reduced;

The connecting shaft 23 penetrates the fixed block 22 and extends to the bottom of the fixed block 22. An eccentric wheel 25 is fixedly sleeved on the part of the connecting shaft 23 located below the fixed block 22. When the fixed clamping block 21 rotates, the connecting shaft 23 is driven to rotate, thereby rotating the eccentric wheel 25 together. When the eccentric wheel 25 rotates, the connecting block 24 is squeezed, thereby deforming and moving the connecting block 24, driving the fixed block 22 to move accordingly, causing the screening net 4 to vibrate, speeding up the screening cylinder of the fertilizer, and preventing part of the fertilizer from adhering to the screening net 4 and blocking the screening net 4.

[0025] A collecting box 8 is provided below the fixing ring 3. The size of the collecting box 8 corresponds to that of the screening box 1. A moving wheel 9 is fixedly connected to the bottom wall of the collecting box 8. A moving groove corresponding to the moving wheel 9 is provided on the lower inner wall of the screening box 1. A fixed cover plate 26 is rotatably provided on the side wall of the screening box 1. The position of the fixed cover plate 26 corresponds to that of the collecting box 8. The screened fertilizer finally falls into the collecting box 8. By opening the fixed cover plate 26, the collecting box 8 can be slid out to obtain the screened fertilizer.

[0026] A partition plate 2 is fixedly connected to the inside of the screening box 1, and the partition plate 2 is arranged between the fixed ring 3 and the vibration structure, and the partition plate 2 is penetrated by the rotating rod 12; a baffle is fixedly connected to the top of the screening net 4, and the baffle blocks the sliding groove 6 to prevent fertilizer from entering the sliding groove 6.

[0027] In the present invention, when the device is in use, the fertilizer is first fed into the screening box 1, and then the motor 10 is started, and its output end drives the rotating rod 11 to rotate, so that the rotating rod 12 rotates accordingly, so that the fixed block 21 and the stirring rod also rotate together to stir the fertilizer, and at the same time, when the rotating rod 11 rotates, the bevel gear 16 rotates, driving the bevel gear 2 17 and the fixed shaft 18 to rotate together, and when the fixed shaft 18 rotates, the elliptical wheel 19 rotates, and when the elliptical wheel 19 rotates, its side wall squeezes the fixed plate 15, and the reset spring 14 can make the fixed plate 15 always stick to the surface of the elliptical wheel 19, so that the fixed plate 15 can move up and down, thereby driving the rotating rod 2 12 to move up and down, so that the screening net 4 and the fixed The ring 3 moves up and down together to lift the fertilizer on the screening net 4. The lifting and falling of the fertilizer can speed up the screening process and prevent stones and other debris from gathering on the surface of the screening net 4, thereby reducing the screening speed. When the fixed block 21 rotates, it will drive the connecting shaft 23 to rotate, so that the eccentric wheel 25 rotates together. When the eccentric wheel 25 rotates, it will squeeze the connecting block 24, so that the connecting block 24 deforms and moves, driving the fixed block 22 to move accordingly, so that the screening net 4 vibrates, speeding up the screening cylinder of the fertilizer, and preventing part of the fertilizer from adhering to the screening net 4 and blocking the screening net 4. The screened fertilizer finally falls into the collecting box 8. Open the fixed cover 26, the collecting box 8 can be slid out to obtain the screened fertilizer.
