At this time, the material enters the middle gap between the limiting ring and the conical block along the inclined edge of the support ring, and then the material is crushed. The material moves inside the gap along the guide groove, so that the material can be evenly distributed in the crushing area. The guide groove can play a role of regularization and guidance, making the feeding smoother, and can guide the material to flow more orderly on the surface of the conical block, avoiding uneven distribution or local accumulation of the material during the crushing process. This helps to improve the crushing efficiency, so that the material can contact the crushing component more fully, and achieve a more uniform crushing effect. The large diameter of the discharge point through the guide groove , to avoid the crushed materials being blocked in the discharge gap and affecting the work efficiency. At the same time, the diameter gradually decreases from top to bottom, so that materials of different sizes can be guided to stay in the crushing chamber, to avoid insufficient crushing of some materials, and to effectively improve the work efficiency.

The two limiting rings 32 are symmetrically arranged with the positioning ring 31 as the center. The inner sides of the limiting rings 32 and the positioning rings 31 increase in diameter from top to bottom. A conical block 35 is fixedly connected to the outer side of the rotating shaft 7. The material is added to the interior of the shell 21 through the feed pipe 5. The motor 6 is connected to an external power supply to work, and the motor 6 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the conical block 35 to rotate. At this time, the material enters along the inclined edge of the support ring 29.

The outer side of the spring plate 341 is fixedly connected to the limiting plate 342. In the initial state, under the action of the self-weight of the limiting ring 32 and the elastic force of the spring plate 341, the limiting ring 32 maintains a balanced state. When the rotating shaft 7 drives the conical block 35 to rotate, the conical block 35 drives the round rod 37 to rotate, and the round rod 37 contacts the upper half of the rotating rod 345. The round rod 37 collides with the rotating rod 345 and exerts a force. The rotating rod 345 drives the extension rod 344 to rotate. At this time, under the support of the connecting rod 343, the two limiting plates 342 are close to each other. As a result, the spring plate 341 is stretched and deformed by the force, so that the limit ring 32 twists and moves downward, and then the crushing plate 39 located on the limit ring 32 is staggered and meshed with the crushing plate 39 located on the positioning ring 31, so as to crush large pieces of material and prevent large pieces of material from being stuck in the crushing chamber. The round rod 37 and the limit plate 342 are configured as L-shaped plates, and the end of the limit plate 342 away from the spring plate 341 is rotatably connected to the connecting rod 343, and the limit plates 342 are symmetrically arranged with the connecting rod 343 as the center. The two ends of the connecting rod 343 are rotatably connected to the two ends of the two limit plates 342, and the middle part of the connecting rod 343 is fixedly connected to the extension rod 344, and the end of the extension rod 344 away from the connecting rod 343 is fixedly connected to the rotating rod 345.

[0017] The third embodiment is based on the first and second embodiments. Figures 8 to 9 As shown, the shell 2 includes an outer shell 21, which is fixedly connected to the frame 1. A support ring 29 is fixedly connected to the inner wall of the outer shell 21. A scraper 22 is fixedly connected to the outer side of the rotating shaft 7. The buffer rod 23 is set to be inclined, and the buffer rod 23 is elastic. The material is added to the interior of the shell 2 through the feed pipe 5. The motor 6 is connected to an external power supply to work, and the motor 6 drives the rotating shaft 7 to rotate, so that the rotating shaft 7 drives the scraper 22 and the buffer rod 23 to rotate. The material contacts the top of the buffer rod 23, and the material moves downward along the buffer rod 23. By setting the buffer rod 23, a buffering effect is played to prevent the material from directly contacting the crushing component, resulting in damage to the crushing component, thereby poor crushing effect. At the same time, the scraper 22 cleans the surface of the support ring 29 to avoid In order to prevent dust from accumulating on the support ring 29 and affecting the material discharge rate, the outer side of the scraper 22 contacts the inner wall of the support ring 29, the top plate of the scraper 22 is fixedly connected with a buffer rod 23, the inner wall of the shell 21 is fixedly connected with a fixing ring 24, the crushing assembly 3 is located between the support ring 29 and the fixing ring 24, the inner wall of the fixing ring 24 is provided with a groove 25, the bottom of the shell 21 is fixedly connected with a discharge hopper 28, the inner wall of the shell 21 is fixedly connected with a circular plate 26, the top of the circular plate 26 is provided with a circular groove 27, and the inner wall of the circular groove 27 is provided with filter holes.

[0018] The grinding assembly 4 includes a connecting ring 41, which is fixedly connected to the outer side of the rotating shaft 7. A fixing rod 42 is fixedly connected to the outer side of the connecting ring 41. There are three fixing rods 42, which are evenly distributed around the connecting ring 41. One end of the fixing rod 42 away from the connecting ring 41 is slidably connected to a sliding block 43. The sliding block 43 and the fixing ring 24 are located on the same horizontal plane. A through hole 412 is provided on the inner wall of the sliding block 43. After the material is crushed, it falls into the circular groove 27. The rotating shaft 7 drives the connecting ring 41 to rotate, and the connecting ring 41 drives the fixing rod 42 to rotate. The fixed rod 42 drives the roller 48 to grind the material inside the circular groove 27, so that the material that meets the standard passes through the filter hole at the bottom of the circular groove 27 and is discharged from the lower hopper 28. At the same time, the sliding block 43 exerts force on the spring 44 under the action of centrifugal force. The spring 44 is stretched and deformed under the force, so that the sliding block moves away from the fixed rod 42, so that the sliding block 43 drives the limit frame 45 at the bottom to move. At this time, the cylinder 46 drives the fixed seat 47 to tilt under the limit of the limit frame 45. At the same time, the sliding block 43 slides inside the fixed ring 24. The groove 25 is uneven, so the sliding block 43 drives the limit frame 45 to move in the radial direction, thereby driving the roller 48 to tilt left and right. By setting the convex strips 410 on the side, the crushing effect is better. The fixing rod 42 is fixedly connected to the inner wall of the through hole 412 with a spring 44. The end of the spring 44 away from the fixing rod 42 is fixedly connected to the sliding block 43. The bottom of the sliding block 43 is fixedly connected to the limit frame 45.

The bottom of the positioning rod 413 is fixedly connected to A fixed seat 47, one end of the fixed seat 47 away from the positioning rod 413 is rotatably connected to a roller 48, and a square plate 49 is fixedly connected to the middle of the outer side of the roller 48. When the roller 48 rotates and grinds, the square plate 49 is deformed by force, thereby increasing the squeezing force between the roller 48 and the material, thereby improving the grinding and crushing effect. At the same time, a cleaning plate is provided to clean the material powder remaining on the surface of the roller 48. A convex strip 410 is fixedly connected to the outer edge of the roller 48, and a cleaning plate 411 is fixedly connected to the outer side of the fixed seat 47, and the cleaning plate 411 is in contact with the outer side of the roller 48.

[0019] When in use, the material is added to the interior of the outer shell 21 through the feed pipe 5, the motor 6 is connected to an external power supply to work, the motor 6 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the conical block 35 to rotate. At this time, the material enters the middle gap between the limit ring 32 and the conical block 35 along the inclined edge of the support ring 29, and then the material is crushed. The material moves inside the gap along the guide groove 36, so that the material can be evenly distributed in the crushing area. The guide groove 36 can play a role in regularization and guidance, making the feeding smoother and guiding the material to flow more orderly on the surface of the conical block 35.

[0020] When the rotating shaft 7 drives the conical block 35 to rotate, the conical block 35 drives the round rod 37 to rotate, the round rod 37 contacts the upper part of the rotating rod 345, and the round rod 37 exerts a force on the rotating rod 345. The rotating rod 345 drives the extension rod 344 to rotate. At this time, under the support of the connecting rod 343, the two limit plates 342 approach each other, so that the spring plate 341 is stretched and deformed by force, so that the limit ring 32 twists and moves downward, and then the crushing plate 39 located on the limit ring 32 is staggered and meshed with the crushing plate 39 located on the positioning ring 31, so as to crush large pieces of material and prevent large pieces of material from being stuck in the crushing chamber.

[0021] After the material is crushed, it falls into the circular groove 27. The rotating shaft 7 drives the connecting ring 41 to rotate, and the connecting ring 41 drives the fixing rod 42 to rotate. The fixing rod 42 drives the roller 48 to grind the material inside the circular groove 27, so that the material that meets the standards passes through the filter holes at the bottom of the circular groove 27 and is discharged from the lower hopper 28. At the same time, the sliding block 43 exerts force on the spring 44 under the action of centrifugal force. The spring 44 is stretched and deformed under the force, so that the sliding block moves in the direction away from the fixing rod 42, so that the sliding block 43 drives the limit frame 45 at the bottom to move. At this time, the cylinder 46 drives the fixing seat 47 to tilt under the limit of the limit frame 45. At the same time, the sliding block 43 slides inside the fixing ring 24. Because the groove 25 is uneven, the sliding block 43 drives the limit frame 45 to move in the radial direction, thereby driving the roller 48 to tilt left and right.
