[0021] The following is combined with Figures 1-4 This application is described in further detail.

[0022] Embodiment 1

[0023] Reference Figure 2 and Figure 3 A particle screening device for compound fertilizer processing includes a cylinder 1, and a feeding port 22 is fixedly arranged on the upper wall of the cylinder 1 and connected to the cylinder 1, and compound fertilizer can be fed into the cylinder 1 through the feeding port 22. A feeding cylinder 9 and a feeding plate 8 are fixedly arranged inside the cylinder 1, and the lower end of the feeding plate 8 is connected to the feeding cylinder 9 and fixedly connected. The upper wall of the feeding plate 8 is an inclined surface, and it slopes from all sides to the connection between it and the feeding cylinder 9, so that the compound fertilizer fed into the cylinder 1 can quickly enter the feeding cylinder 9.

[0024] Reference Figure 2 and Figure 3 A rotating rod 2 is rotatably arranged inside the cylinder 1, and a screw 10 is sleeved and coaxially fixedly connected to the rotating rod 2. The screw 10 is located inside the feeding cylinder 9, and the screw 10 facilitates the breaking up and downward transportation of the compound fertilizer. The rotating rod 2 is coaxially fixedly connected to a breaking knife 11 at the upper end of the feeding cylinder 9, and the breaking knife 11 is rotated for the preliminary breaking up of the compound fertilizer. A screen 14 is slidably connected inside the cylinder 1, and a plurality of evenly distributed screen holes are arranged through the screen 14, and the screen holes are used for screening the compound fertilizer particles.

[0025] Reference Figure 4 Four movable grooves 19 are provided on the side wall of the cylinder 1, and connecting blocks 18 are slidably provided in the movable grooves 19. The lower walls of the connecting blocks 18 are fixedly connected with telescopic columns 20, and the lower ends of the telescopic columns 20 are fixedly connected to the lower walls of the movable grooves 19. The connecting blocks 18 are elastically connected to the lower walls of the movable grooves 19 through springs 21, and the connecting blocks 18 are fixedly connected to the side walls of the screen 14.

[0026] Reference Figures 1-4The lower end of the rotating rod 2 is fixedly connected with a cross bar 12, and the lower end of the cross bar 12 is fixedly connected with a toggle block 13. The two side walls of the toggle block 13 are set as inclined surfaces to facilitate the smooth passage of the toggle block 13. Four fixed blocks 17 are fixedly set on the upper wall of the screen 14. The upper ends of the fixed blocks 17 are all rotatably connected with balls 16. The toggle blocks 13 work in coordination with the balls 16. When the rotating rod 2 rotates, the cross bar 12 drives the toggle block 13 to rotate with the center of the cylinder 1 as the center of the circle. After the fixed block 17 abuts against the balls 16, it continues to rotate and squeezes the balls 16 to drive the screen 14 to descend. After the fixed block 17 passes, the screen 14 moves upward due to the setting of the telescopic column 20 and the spring 21, that is, the rotating rod 2 rotates, driving the screen 14 to move up and down.

[0027] Reference Figure 3 The lower wall of the cylinder 1 is fixedly provided with a discharge port 7 and connected thereto. An inclined plate 15 is fixedly provided on the lower wall of the cylinder 1. The inclined plate 15 slopes toward one side of the discharge port 7 and cooperates therewith. The lower end thereof is flush with the lower wall of the discharge port 7. The screened compound fertilizer particles slide toward the discharge port 7 through the setting of the inclined plate 15 and are discharged through the discharge port 7.

[0028] Reference Figure 1 A fixing plate 5 is fixedly provided on the upper wall of the cylinder 1, and a worm 4 is rotatably provided on the fixing plate 5. A motor 3 for driving the worm 4 to rotate is fixedly provided on the upper wall of the cylinder 1. A rotating rod 2 passes through the upper wall of the cylinder 1 and is rotatably connected thereto. A worm wheel 6 is coaxially fixedly connected to the upper end of the rotating rod 2, and the worm 4 is meshed with the worm wheel 6.

[0029] The implementation principle of a particle screening device for compound fertilizer processing in the embodiment of the present application is:

[0030] First, compound fertilizer particles are put into the barrel 1 through the feeding port 22, and the motor 3 is started to rotate the worm 4, driving the worm gear 6 meshing with it to rotate, so that the rotating rod 2 coaxially fixedly connected with it rotates, and the rotating rod 2 drives the scattering knife 11 to rotate to initially scatter the agglomerated compound fertilizer, and the compound fertilizer is quickly entered into the feeding barrel 9 through the inclined surface setting of the feeding plate 8, and the rotating rod 2 drives the screw 10 to rotate to further scatter the agglomerated compound fertilizer particles, which is convenient for subsequent screening; due to the rotation of the rotating rod 2, the cross bar 12 drives the toggle block 13 to rotate, and the inclined surface setting of the toggle block 13 makes it press the screen 14 downward after it abuts against the ball 16, and the setting of the telescopic column 20 and the spring 21 makes the screen 14 move upward after the toggle block 13 turns away, that is, the rotation of the rotating rod 2 makes the screen 14 move up and down, reducing the possibility of blockage of the screen 14 and improving the working efficiency. For the larger particles retained above the screen 14, the fan can be opened by rotating the side wall of the barrel 1 to take them out.
