On the inner wall of the crushing box 1, the other end shafts of the crushing rollers 42 penetrate the crushing box 1 and are connected through the transmission structure, and one end shaft of one of the crushing rollers 42 is fixedly connected to the output end of the first motor 41, and the surface of the crushing rollers 42 is welded with a plurality of equally spaced crushing knives 43, and the transmission structure includes a driving wheel 51, a driven wheel 52 and a belt 53, and a plurality of driving wheels 51 are welded on the surface of the shaft of the crushing roller 42 connected to the output end of the first motor 41, and a plurality of driven wheels 51 are welded on the surface of the other crushing rollers 42, and the driven wheels 52 are distributed side by side with the driving wheels 51, and the driven wheels 52 and the driving wheels 51 are respectively connected through belts 53.

[0026] When in use, the operator starts the first motor 41, and when the output end of the first motor 41 rotates, the shaft of the crushing roller 42 connected thereto is driven to rotate accordingly. When the shaft of the crushing roller 42 rotates, the driving wheel 51 rotates accordingly, thereby driving the other crushing rollers 42 to rotate accordingly through the belt 53, and then the crushing roller 42 drives the crushing knife 43 to rotate and operate, thereby performing the initial crushing treatment on the compound fertilizer raw materials.

[0027] A crushing assembly for crushing the compound fertilizer raw materials again is provided inside the crushing box 2, and the crushing assembly includes a second motor 61, a crushing roller 62, an electric push rod 63 and a crushing plate 64. The second motor 61 is installed on one side of the crushing box 2 by bolts, and one end of the rotating shaft of the crushing roller 62 is rotatably connected to one side of the inner wall of the crushing box 2 through a bearing seat, and the other end of the rotating shaft of the crushing roller 62 passes through the crushing box 2 and is fixedly connected to the output end of the second motor 61.

One end of the connecting plate 71 extends out of the interior of the sliding groove 18 and is welded to one side of the filter plate 14. The round rod 72 is used to prevent the connecting plate 71 from escaping from the interior of the sliding groove 18. The other end of the filter plate 14 is slidably connected to the inside of the feeding channel 13. The filter plate 14 is inclined and is used to screen the compound fertilizer raw materials after secondary crushing. The qualified ones will be discharged from the inside of the crushing box 2 through the discharging hopper 11, and the larger compound fertilizer raw materials will slide to the inclined end of the filter plate 14 and enter the next operation through the feeding channel 13.

[0030] The filter plate 14 is located on one side of the feeding channel 13 and is provided with a feeding assembly for feeding and re-crushing the compound fertilizer raw materials that are not completely crushed after screening by the filter plate 14. The feeding assembly includes a third motor 81, a rotating rod 82 and a spiral blade 83. The third motor 81 is installed on the top of the feeding box 3 by bolts. The output end shaft of the third motor 81 extends to the inside of the feeding box 3 and is connected to the rotating rod 82. The surface of the rotating rod 82 is welded with a spiral blade 83. When larger compound fertilizer raw materials enter the feeding box 3 through the feeding channel 13, the third motor 81 is started. When the output end of the third motor 81 rotates, the spiral blade 83 is driven to rotate by the rotating rod 82, thereby conveying the larger compound fertilizer raw materials, so that they enter the inside of the crushing box 1 again through the discharge channel 12 for re-crushing. The effect of automatic cycle crushing can be achieved without manual re-feeding, thereby improving the crushing efficiency of the compound fertilizer raw materials and reducing labor.

The shaking assembly includes a cam 91, a return spring 92, an extrusion block 93, an extrusion rod 94 and a connecting rod 95. The other end of the rotating rod 82 passes through the bottom of the feeding box 3 and is welded with the cam 91. The side of the crushing box 2 close to the cam 91 is welded with a return spring 92. The other end of the return spring 92 is welded to one side of the extrusion block 93. The side of the extrusion block 93 close to the cam 91 is provided with an active groove 19 matching the cam 91. One side of the cam 91 is in contact with the inside of the active groove 19. The side of the extrusion block 93 away from the cam 91 is welded with an extrusion spring 93 that passes through the return spring 92 and extends to the inside of the crushing box 2. Rod 94, one end of the extrusion rod 94 is hingedly connected to a connecting rod 95, and one end of the connecting rod 95 away from the extrusion rod 94 is hingedly connected to the bottom end of the filter plate 14. When in use, when the rotating rod 82 rotates, the cam 91 is driven to rotate accordingly. When the cam 91 rotates, its long end squeezes the extrusion block 93, so that the return spring 92 is compressed and deformed. At the same time, the extrusion rod 94 slides toward the inside of the crushing box 2. When the extrusion rod 94 slides, the filter plate 14 slides up and down inside the crushing box 2 through the hinged connecting rod 95, so that the filter plate 14 vibrates the compound fertilizer raw materials on the surface, quickly screens them, and prevents the accumulated compound fertilizer raw materials from clogging the filter plate 14.

[0032] Working principle: When the compound fertilizer raw material crushing device is ready to be used, the operator first starts the electric push rod 63 to drive the cutting knife 66 to move toward the surface close to the crushing knife 65 through the crushing plate 64, thereby adjusting the particle size of the compound fertilizer raw material to be crushed, and then conveys the compound fertilizer raw material into the crushing box 1 through the feed hopper 10, starts the first motor 41 to drive the crushing assembly to operate through the transmission structure, and performs the initial crushing of the compound fertilizer raw material in the crushing box 1. The compound fertilizer raw material after the initial crushing enters the crushing box 2, and starts the second motor 61 to drive the crushing assembly to operate to crush the compound fertilizer raw material again, so that it is crushed more evenly, and the crushed compound fertilizer raw material falls on the top of the filter plate 14, and at the same time Start the third motor 81 to control the operation of the feeding component. When the feeding component is running, the shaking component is operated through the rotating rod 82, so that the filter plate 14 slides up and down and vibrates inside the crushing box 2, and then the compound fertilizer raw materials crushed on its surface are vibrated and screened. Qualified compound fertilizer raw materials will pass through the filter plate 14 and be discharged from the crushing box 2 through the discharge hopper 11. Larger compound fertilizer raw materials will slide to the inclined end of the filter plate 14 and enter the feeding box 3 through the feeding channel 13. After being transported by the spiral blade 83, they will enter the inside of the crushing box 1 again from the discharge channel 12 for automatic cycle crushing processing. There is no need for manual screening and feeding, which saves time and effort and improves the crushing efficiency of the compound fertilizer raw materials.
