[0012] Preferably, the crushing box and the discharge box are fixedly connected to each other on one side.

[0013] A method of using a bio-organic fertilizer processing and pulverizing device includes the following steps:

[0014] S1: Coarse crushing process: Start the first motor and the second motor. The first motor drives the rotating disk and connecting rod to rotate through the first rotating shaft. The crushing disc rotates at high speed under the action of centrifugal force, which impacts and coarsely crushes the organic fertilizer put into the first crushing chamber. The second motor drives the two sets of second rotating shafts to rotate through the first transmission belt. The rotating rod rotates with the second rotating shaft. The rubber head elastically impacts the filter screen under the action of the spring to prevent the material from clogging the filter screen.

[0015] S2: Material guiding and fine crushing process: After coarse crushing, the material that meets the particle size requirements passes through the filter screen and is guided into the second crushing chamber through the first inclined platform, the connecting groove and the second inclined platform. The third motor is started, and the third motor drives the lower rotating drum on one side to rotate. Through the reversing gear, the third rotating shaft and the second transmission belt, the lower rotating drum on the other side is driven to rotate in the opposite direction. The lower rotating drum drives the upper bevel gear through the lower bevel gear and the reversing bevel gear to drive the upper rotating drum to rotate in the opposite direction. This causes the first crushing plate and the second crushing plate to shear each other. At the same time, the crushing plate and the filter plate rub against each other to achieve fine crushing of the material.

[0016] S3: Screening and Discharging Process: The finely crushed material falls into the discharge box and is guided to the guide plate by the third inclined platform. The guide plate rotates around the fifth rotating shaft under the impact of the material, guiding the material to the screening plate. Qualified fine particles are discharged through the screening plate, while unqualified coarse particles slide along the screening plate into the discharge box for collection. The torsion spring drives the guide plate and the screening plate to rotate back and forth to ensure the flowability of the material.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The present invention achieves coarse crushing and breaks up blocky materials through the hammer-type structure of the first crushing chamber; the second crushing chamber is driven by bevel gears, so that the first crushing plate and the second crushing plate are sheared in opposite directions. Combined with the friction between the crushing plate and the filter plate, the material particle size is uniform and the fine crushing effect is significant, which meets the requirements of fine processing of bio-organic fertilizer.

[0019] 2. The present invention also automatically separates qualified fine particles from unqualified coarse particles by using a guide plate and a screening plate. Qualified materials are discharged directly, while unqualified materials are collected and crushed again without the need for additional screening equipment. The torsion spring drives the guide plate and the screening plate to rotate back and forth, ensuring material flowability, avoiding material accumulation, and improving screening efficiency.

[0037] A method of using a biological organic fertilizer processing and pulverizing device includes the following steps: S1: Coarse pulverizing process: Start the first motor 4 and the second motor 14. The first motor 4 drives the rotating disk 6 and the connecting rod 7 to rotate through the first rotating shaft 5. The pulverizing disc 8 rotates at high speed under the action of centrifugal force to impact and coarsely pulverize the organic fertilizer put into the first pulverizing chamber 3. The second motor 14 drives the two sets of second rotating shafts 10 to rotate through the first transmission belt 12. The rotating rod 11 rotates with the second rotating shaft 10. The rubber head 17 elastically impacts the filter screen 9 under the action of the spring 18 to prevent the material from clogging the filter screen 9.

[0038] S2: Material guiding and fine crushing process: After coarse crushing, the material that meets the particle size requirements passes through the filter screen 9, and is guided into the second crushing chamber 22 through the first inclined platform 23, the connecting groove 20 and the second inclined platform 36. The third motor 40 is started, and the third motor 40 drives the lower rotating drum 27 on one side to rotate. Through the reversing gear 38, the third rotating shaft 37 and the second transmission belt 39, the lower rotating drum 27 on the other side rotates in the opposite direction. The lower rotating drum 27 drives the upper bevel gear 30 through the lower bevel gear 28 and the reversing bevel gear 29 to drive the upper rotating drum 31 to rotate in the opposite direction, so that the first crushing plate 34 and the second crushing plate 35 are sheared alternately. At the same time, the crushing plate and the filter plate 41 rub against each other to achieve fine crushing of the material.

[0039] S3: Screening and Discharging Process: The finely pulverized material falls into the discharge box 2 and is guided to the guide plate 46 by the third inclined platform 48. The guide plate 46 rotates around the fifth rotating shaft 45 under the impact of the material, guiding the material to the screening plate 44. Qualified fine particles are discharged through the screening plate 44, while unqualified coarse particles slide along the screening plate 44 into the discharge box 49 for collection. The torsion spring 47 drives the guide plate 46 and the screening plate 44 to rotate back and forth to ensure the flowability of the material.

[0040] Working principle: When using this invention: the raw materials for bio-organic fertilizer to be crushed are evenly fed into the first crushing chamber 3; the first motor 4 drives the first rotating shaft 5, rotating disk 6, and connecting rod 7 to rotate at high speed, and the crushing blades 8 unfold under the action of centrifugal force to impact and coarsely crush the raw materials, breaking up the lumpy materials; simultaneously, the second motor 14 drives the two sets of second rotating shafts 10 to rotate through the first transmission belt 12, and the rotating rod 11 drives the sliding rod 16 and the rubber head 17 to rotate. Under the elastic action of the spring 18, the rubber head 17 periodically impacts the filter screen 9, shaking off the attached coarse particles and preventing the filter screen from clogging; the coarsely crushed materials that meet the particle size requirements pass through the filter screen 9 and enter the next process; the coarse particles that do not meet the standards are intercepted and continue to be impacted and crushed by the crushing blades 8 in the first crushing chamber 3;

[0041] The coarsely crushed material enters the second crushing chamber 22. The third motor 40 drives the lower rotating drum 27 on one side to rotate, which in turn drives the third rotating shaft 37 to rotate via the reversing gear 38. The second transmission belt 39 drives the lower rotating drum 27 on the other side to rotate in the opposite direction. The lower rotating drum 27 drives the lower bevel gear 28 to rotate, which in turn drives the upper bevel gear 30 to rotate in the opposite direction to the upper rotating drum 31 via the meshing transmission of the reversing bevel gear 29. The first crushing plate 34 and the second crushing plate 35 rotate alternately in opposite directions to shear and crush the material. At the same time, the friction between the outer side of the crushing plate and the filter plate 41 further refines the particle size of the material, completing the fine crushing.

[0042] The finely pulverized material falls into the discharge box 2 and is guided to the guide plate 46 by the third inclined platform 48. The material impacts the guide plate 46, causing it to rotate around the fifth rotating shaft 45, which guides the material evenly to the screening plate 44. Fine particles that meet the particle size requirements are discharged through the sieve holes of the screening plate 44 and collected as finished products. Coarse particles that do not meet the particle size requirements slide along the inclined screening plate 44 into the discharge box 49, are collected, and can be put back into the first pulverizing chamber 3 for secondary pulverization. The torsion spring 47 elastically resets after the material impacts, driving the guide plate 46 and the screening plate 44 to rotate back and forth, preventing material from accumulating on the surface and ensuring flowability.

9. A method of using the bio-organic fertilizer processing and pulverizing device according to claims 1-8, characterized in that: Includes the following steps: S1: Coarse crushing process: Start the first motor (4) and the second motor (14). The first motor (4) drives the rotating disk (6) and the connecting rod (7) to rotate through the first rotating shaft (5). The crushing plate (8) rotates at high speed under the action of centrifugal force to crush the organic fertilizer put into the first crushing chamber (3). The second motor (14) drives the two sets of second rotating shafts (10) to rotate through the first transmission belt (12). The rotating rod (11) rotates with the second rotating shaft (10). The rubber head (17) elastically impacts the filter screen (9) under the action of the spring (18) to prevent the material from clogging the filter screen (9). S2: Material guiding and fine crushing process: After coarse crushing, the material that meets the particle size requirements passes through the filter screen (9), and is guided into the second crushing chamber (22) through the first inclined platform (23), the connecting groove (20) and the second inclined platform (36). The third motor (40) is started, and the third motor (40) drives the lower rotating drum (27) on one side to rotate. Through the reversing gear (38), the third rotating shaft (37) and the second transmission belt (39), the lower rotating drum (27) on the other side is driven to rotate in the opposite direction. The lower rotating drum (27) drives the upper bevel gear (30) through the lower bevel gear (28) and the reversing bevel gear (29) to drive the upper rotating drum (31) to rotate in the opposite direction, so that the first crushing plate (34) and the second crushing plate (35) are interleaved and sheared. At the same time, the crushing plate and the filter plate (41) rub against each other to achieve fine crushing of the material. S3: Screening and Discharging Process: The finely crushed material falls into the discharge box (2) and is guided to the guide plate (46) by the third inclined platform (48). The guide plate (46) rotates around the fifth rotating shaft (45) under the impact of the material, guiding the material to the screening plate (44). Qualified fine particles are discharged through the screening plate (44), and unqualified coarse particles slide into the discharge box (49) along the screening plate (44) for collection. The torsion spring (47) drives the guide plate (46) and the screening plate (44) to rotate back and forth to ensure the flowability of the material.
