[0002] Agricultural fertilizers are substances that provide the nutrients needed for plant growth, improve soil properties, and increase crop yield and quality. They are one of the core inputs in agricultural production. Agricultural fertilizer raw material crushing equipment is a machine used to crush various fertilizer raw materials into smaller particles or powders to meet the requirements of subsequent fertilizer production processes. However, when raw materials are put into the existing agricultural fertilizer raw material crushing equipment, they tend to fall into the dead corners of the crushing wheel. The position of the raw materials needs to be manually adjusted for crushing. Moreover, after crushing the raw materials, debris tends to stick to the crushing teeth, which affects subsequent crushing processing. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a raw material crushing equipment for agricultural fertilizer production, which solves the problems of existing agricultural fertilizer raw material crushing equipment where raw materials are easily put into the edge dead corner of the crushing wheel when the equipment is put in, requiring manual adjustment of the raw material position for crushing, and the crushing wheel easily sticking to the crushing teeth after crushing the raw materials, affecting subsequent crushing processing.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a raw material crushing device for agricultural fertilizer production, comprising a processing box, an inlet fixedly installed on the top of the processing box, two guide plates rotatably connected to the top two sides of the inlet via pins, two rotating seats symmetrically fixedly installed on the bottom of the guide plates and the inner side of the inner wall of the inlet, a damping telescopic rod fixedly connected between each pair of opposing rotating seats, a buffer spring sleeved on the surface of the damping telescopic rod between the two rotating seats, an outlet provided on one bottom side of the processing box, and the inner wall of the processing box... Two crushing wheels are rotatably connected by bearings. Three guide rods slide through each side of the processing box. A limit plate is fixedly connected to one end of each guide rod on the outside of the processing box. A mounting frame is fixedly installed on the side of each guide rod away from the limit plate, and the two ends of the mounting frame slide between the inner walls of the processing box. A compression spring is sleeved between the guide rod and the inner wall of the processing box and the mounting frame. A cleaning brush is rotatably connected between the inner walls of the mounting frame and the crushing wheels through a rotating shaft. The inner walls of the processing box are symmetrically provided with sliding grooves on both sides, and the mounting frame slides inside the sliding grooves.
[0005] As a further embodiment of this utility model: a connecting seat is fixedly installed at the bottom of the processing box, and a material collection bin is slidably installed inside the connecting seat, with the material collection bin corresponding to the position of the discharge port.
[0006] As a further embodiment of this utility model: rolling wheels are fixedly installed at the four corners of the bottom of the collection bin, and two rolling grooves are provided at the bottom of the connecting seat, and the rolling wheels roll inside the rolling grooves.
[0007] As a further embodiment of this utility model: mounting blocks are symmetrically and fixedly installed on one side of the collection bin, and a snap-fit plate is slidably connected inside the mounting block. Snap-fit blocks are fixedly installed at both ends of one side of the connecting seat, and the positions of the snap-fit blocks and the snap-fit plates correspond to each other.
[0008] As a further embodiment of this utility model: the middle of the snap-fit plate is rotatably connected to a rotating snap-fit plate via a pin shaft, and the rotating snap-fit plate is snapped onto the surface of the mounting block.
[0009] As a further embodiment of this utility model: three telescopic connecting rods are fixedly installed on one side of the inner wall of the connecting seat, and a push plate is fixedly connected to one end of the three telescopic connecting rods. The push plate is in close contact with one side of the collection bin, and a return spring is sleeved on the surface of the telescopic connecting rod between the push plate and the connecting seat.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This raw material crushing equipment for agricultural fertilizer production, by setting up a guide plate, a cleaning brush, and a clamping spring, allows fertilizer raw materials to be poured into the processing box. When the raw materials pass through the guide plate, the buffer spring is compressed. At the same time, the damping telescopic rod consumes the elastic potential energy of the buffer spring, buffering the guide plate and allowing it to smoothly guide the raw materials between the two crushing wheels. When the crushing teeth of the crushing wheels roll, they pass through the cleaning brush, causing the cleaning brush to squeeze the clamping spring. This causes the clamping spring to press against the mounting frame, making the cleaning brush stick to the surface of the crushing wheel and sweeping away impurities on the surface of the crushing wheel, thereby improving the crushing efficiency of the device.
[0011] 2. This raw material crushing equipment for agricultural fertilizer production, by setting up a collection bin and rolling wheels, allows the crushed raw materials to fall into the collection bin through the discharge port. Rotating the rotating clamping plate away from the bottom of the mounting block and pulling the clamping plate away from the top of the clamping block, and then snapping the rotating clamping plate into the top of the mounting block, causes the return spring to return and push the push plate to pop the collection bin out of the connecting seat. The rolling wheels slide inside the rolling groove, reducing the resistance to the movement of the collection bin and making it easier for workers to pull the collection bin out of the connecting seat to collect the crushed raw materials.

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0014] like Figure 1-3 As shown, this utility model provides a technical solution: a raw material crushing device for agricultural fertilizer production, including a processing box 1. A feed inlet 2 is fixedly installed on the top of the processing box 1. Two guide plates 5 are rotatably connected to the top two sides of the feed inlet 2 via pins. Two rotating seats 4 are symmetrically fixedly installed on the bottom of the guide plates 5 and the inner side of the inner wall of the feed inlet 2, respectively. A damping telescopic rod 3 is fixedly connected between each pair of opposite rotating seats 4. A buffer spring 8 is sleeved on the surface of the damping telescopic rod 3 between the two rotating seats 4. A discharge port 6 is provided on one bottom side of the processing box 1. Two crushing wheels 9 are rotatably connected to the middle of the inner wall of the processing box 1 via bearings. With the guide plates 5, the fertilizer raw materials fall into the processing box 1 through the guide plates 5, making it easier for the raw materials to fall between the two crushing wheels 9 for crushing, avoiding manual adjustment of the raw material position inside the processing box 1, thereby reducing the risk of injury during operation.
[0015] Three guide rods 10 slide through both sides of the processing box 1. One end of each guide rod 10 located on the outside of the processing box 1 is fixedly connected to a limiting plate 11. A mounting bracket 12 is fixedly installed on the side of each guide rod 10 away from the limiting plate 11, and both ends of the mounting bracket 12 slide between the inner walls of the processing box 1. A compression spring 14 is sleeved between the guide rod 10 and the inner wall of the processing box 1 and the mounting bracket 12. A cleaning brush 13 is rotatably connected between the inner walls of the mounting bracket 12 via a rotating shaft, and the cleaning brush 13 is in close contact with the crushing wheel 9. Sliding grooves 7 are symmetrically provided on both sides of the inner wall of the processing box 1, and the mounting bracket 12 slides inside the sliding grooves 7. By providing the guide rods 10 and allowing them to slide inside the processing box 1, the mounting bracket 12 moves within the sliding grooves 7, thus preventing the cleaning brush 13 from shifting during movement.
[0016] A connecting seat 15 is fixedly installed at the bottom of the processing box 1. A material collection bin 17 is slidably installed inside the connecting seat 15, and the position of the material collection bin 17 corresponds to that of the discharge port 6. By providing the material collection bin 17, the material collection bin 17 stores the crushed raw materials falling from the discharge port 6, which is convenient for periodically taking out the crushed raw materials for the next step of processing.
[0017] Rolling wheels 18 are fixedly installed at the four corners of the bottom of the collection bin 17. Two rolling grooves 16 are provided at the bottom of the connecting seat 15, and the rolling wheels 18 roll inside the rolling grooves 16. By providing the rolling wheels 18, when the collection bin 17 is pulled out from the inside of the connecting seat 15, the rolling wheels 18 roll inside the rolling grooves 16, reducing the friction between the collection bin 17 and the connecting seat 15, thereby making the movement of the collection bin 17 smoother and less labor-intensive.
[0018] A mounting block 19 is symmetrically fixedly installed on one side of the collection bin 17. A snap-fit plate 20 is slidably connected inside the mounting block 19. Snap-fit blocks 22 are fixedly installed at both ends on one side of the connecting seat 15, and the snap-fit blocks 22 correspond to the snap-fit plates 20. By providing snap-fit plates 20, the snap-fit plates 20 are snapped into the snap-fit blocks 22, thus fixing the collection bin 17 inside the connecting seat 15 and ensuring that the collection bin 17 does not easily slide out of the connecting seat 15.
[0019] The snap-fit plate 20 is rotatably connected to the rotating snap-fit plate 21 through a pin shaft in the middle, and the rotating snap-fit plate 21 is snapped onto the surface of the mounting block 19. By providing the rotating snap-fit plate 21, the rotating snap-fit plate 21 is fastened to the bottom of the mounting block 19, making it difficult for the snap-fit plate 20 to move inside the mounting block 19, and making the snap-fit plate 20 more stable when it is fastened into the snap-fit block 22.
[0020] Three telescopic connecting rods 23 are fixedly installed on one side of the inner wall of the connecting seat 15. One end of the three telescopic connecting rods 23 is fixedly connected to a push plate 25, and the push plate 25 is close to one side of the collection bin 17. A return spring 24 is sleeved on the surface of the telescopic connecting rod 23 between the push plate 25 and the connecting seat 15. By providing a return spring 24, the return spring 24 rebounds, causing the push plate 25 to push the collection bin 17 out of the connecting seat 15, assisting the collection bin 17 to move and making it easier to remove the collection bin 17.
[0021] The working principle of this utility model is as follows: When fertilizer raw materials are poured into the feed inlet 2, the pressure spring 8 and damping telescopic rod 3 are compressed when the raw materials are at the top of the guide plate 5. At this time, the damping telescopic rod 3 resets, consuming the elastic potential energy of the pressure spring 8, thus buffering the guide plate 5 and stabilizing it. This allows the raw materials to fall steadily between the two crushing wheels 9 for crushing. Simultaneously, as the crushing wheels 9 rotate, the cleaning brush 13 rubs against the surface of the crushing wheels 9. The crushing wheels 9 press against the moving mounting bracket 12, causing the compression spring 14 to compress. This causes the compression spring 14 to rebound and push the mounting bracket 12, making the cleaning brush 13 adhere to the surface of the crushing wheels 9. The cleaning brush 13 then cleans the debris adhering to the surface of the crushing wheels 9, improving the crushing efficiency of the crushing wheels 9. To extend the service life of the device, after the raw material is crushed and processed, the crushed raw material falls into the collection bin 17 through the discharge port 6. Rotate the rotating clamping plate 21 away from the bottom of the mounting block 19, pull the clamping plate 20 away from the top of the clamping block 22, and then rotate the rotating clamping plate 21 into the top of the mounting block 19 to prevent the clamping plate 20 from slipping. At this time, the return spring 24 returns to its original position, causing the telescopic connecting rod 23 to extend and push the push plate 25 to move, so that the push plate 25 pushes the collection bin 17 away from the inside of the connecting seat 15. At the same time, the rolling wheel 18 rolls inside the rolling groove 16, making it easier to pull the collection bin 17. Then, the raw material inside the collection bin 17 is transported to the next processing step to complete the collection of crushed raw materials.
