A circular scraper 7 is dynamically connected, and the circular scraper 7 is provided with grooves 70 equal to the number of the fixed plate 6. The fixed plates 6 are all in adjacent grooves 70, so that the circular scraper 7 is fully in contact with the inner wall of the crushing box 1 and the fixed plate 6, so that the inner wall of the crushing box 1 and the fixed plate 6 can be fully scraped. The fixed plates 6 are all slidably connected to the circular scraper 7. The crushing box 1 is provided with a driving component for making the circular scraper 7 slide up and down and a blowing component for blowing air to the crushing knife 5. The lower part of the electric rotating rod 4 is rotatably connected to a rotating plate 9, and the rotating plate 9 rotates at the bottom of the crushing box 1. A sliding block 10 is slidably connected to the side of the rotating plate 9 close to the inner wall of the crushing box 1. Two compression springs 12 are fixed between the sliding block 10 and the rotating plate 9. A corrugated sleeve 11 is provided at the sliding connection between the rotating plate 9 and the sliding block 10, so as to prevent Chinese medicinal materials from entering the sliding connection between the rotating plate 9 and the sliding block 10.

[0033] refer to Figure 1-Figure 4 The driving assembly includes a telescopic rod 71, a rotating rod 72, a rotating disk 73, a sealing tube 74, a slider 75, a return spring 76 and a sealing ring 78. Four telescopic rods 71 ​​are fixedly connected between the circular scraper 7 and the lower part of the crushing box 1. A sealing ring 78 is fixedly connected between the lower parts of the four telescopic rods 71. The lower part of the crushing box 1 is rotatably connected to the rotating disk 73. The upper part of the rotating disk 73 is provided with an annular groove 77. The sealing ring 78 slides on the upper part of the annular groove 77. The telescopic rod 71 extends into the annular groove 77 through the sealing ring 78. Thereby, a closed space is formed between the annular groove 77 and the telescopic rod 71. A rotating rod 72 is fixedly connected to the lower end of the electric rotating rod 4. The rotating rod 72 passes through the crushing box 1 and the unloading rack 3 and is connected to the rotating disk 73. A plurality of sealing tubes 74 are fixedly connected between the lower part of the rotating rod 72 and the annular groove 77 on the rotating disk 73. Slide blocks 75 are slidably connected in the sealing tubes 74. Reset springs 76 are fixedly connected between the slide blocks 75 and adjacent sealing tubes 74. There is also a closed space between adjacent slide blocks 75 and the annular grooves 77.

[0034] refer to Figure 1 and Figure 5-Figure 8 The blowing assembly includes an air pump 81, a connecting pipe 82, a rotating ring 83 and a turbine 85. The air pump 81 is installed on the upper part of the crushing box 1, and the rotating ring 83 is rotatably connected to the upper part of the electric rotating rod 4. A plurality of air inlet holes 84 are opened on the upper part of the electric rotating rod 4, and the rotating ring 83 just covers the air inlet holes 84. A connecting pipe 82 is fixedly connected between the rotating ring 83 and the air pump 81, and a turbine 85 is fixedly connected to the left part of the rotating plate 9.

[0035] The Chinese medicinal materials that need to be crushed are added from the feeding hopper 2, and the Chinese medicinal materials will fall from the feeding hopper 2 into the crushing box 1. At the same time, the electric rotating rod 4 is controlled so that the electric rotating rod 4 drives the crushing knife 5 to rotate together, and the crushing knife 5 can then crush the Chinese medicinal materials in the crushing box 1, and then through the fixed plate 6 on the inner wall of the crushing box 1, the Chinese medicinal materials in the crushing box 1 can be crushed more completely. After the Chinese medicinal materials are crushed, they will fall onto the unloading rack 3 through the leakage hole 21. Since the upper part of the unloading rack 3 is inclined, the crushed Chinese medicinal materials will slide to the filter screen 31, and then be filtered through the filter screen 31, so as to obtain Chinese medicinal materials of the desired size. At the same time, the Chinese medicinal materials that are not completely crushed will fall from the right part of the unloading rack 3, and then the Chinese medicinal materials that are not completely crushed can be added to the feeding hopper 2 for further secondary crushing.

[0036] The cam 75 is in the state of being moved upward by the push-pull mechanism 71, so that the push-pull mechanism 71 is in a state of being moved upward by the push-pull mechanism 71, and the push-pull mechanism 72 is in a state of being moved upward by the push-pull mechanism 71. When the electric rotating rod 4 stops rotating, the rotating rod 72 and the sealing tube 74 also stop rotating. At this time, there is no centrifugal force, and the reset spring 76 recovers, so that the slider 75 slides along the sealing tube 74 in the direction close to the rotating rod 72 to restore to its original position. At this time, the air in the annular groove 77 no longer squeezes the telescopic rod 71, and the telescopic rod 71 moves downward to recover, so that the circular scraper 7 moves downward to scrape the inner wall of the crushing box 1 and the fixed plate 6 for the second time, thereby ensuring that the inner wall of the crushing box 1 and the fixed plate 6 are completely scraped.

[0037] At the same time, the air pump 81 is controlled so that air enters the rotating ring 83 through the connecting pipe 82, then enters the electric rotating rod 4 through the air inlet 84, and then blows to the adjacent crushing knife 5 through the air outlet pipe 8, thereby blowing off the Chinese medicinal materials remaining on the crushing knife 5. The air entering the electric rotating rod 4 will flow downward, which will cause the turbine 85 to rotate. The rotation of the turbine 85 will drive the rotating plate 9 to rotate together. The rotating plate 9 will rotate together and can scrape and clean the bottom of the crushing box 1, thereby preventing Chinese medicinal materials from remaining at the bottom of the crushing box 1, thereby ensuring that no Chinese medicinal materials will remain in the crushing box 1 after the Chinese medicinal materials are crushed. During the rotation of the rotating plate 9, the sliding block 10 will be driven to rotate together. The rotation of the sliding block 10 will contact the telescopic rod 71 moving upward. At this time, the telescopic rod 71 will squeeze the sliding block 10, so that the sliding block 10 slides in the direction close to the rotating plate 9, the corrugated sleeve 11 contracts, and the compression spring 12 is compressed. The sliding block 10 continues to rotate with the rotating plate 9 and separates from the telescopic rod 71. At this time, the compression spring 12 recovers, the corrugated sleeve 11 recovers, and the sliding block 10 returns to its original position in the direction away from the rotating plate 9, so that the sliding block 10 continues to scrape the bottom of the crushing box 1.

[0038] Example 2: Based on Example 1, refer to Fig.10 and Fig.11 , also includes a knocking mechanism, the knocking mechanism includes a roller 131, a knocking plate 132, a torsion spring 133, a protrusion 134 and a fixed rod 136, the roller 131 is rotatably connected between two adjacent grooves 70 of the circular scraper 7, a plurality of protrusions 134 are fixedly connected on both sides of the roller 131, a fixed rod 136 is also fixedly connected between two adjacent grooves 70 of the circular scraper 7, both ends of the fixed rod 136 are rotatably connected with a knocking plate 132, a torsion spring 133 is fixedly connected between the knocking plate 132 and the adjacent fixed rod 136, the lower part of the knocking plate 132 is in contact with the crushing box 1, the counterclockwise rotation of the protrusion 134 will squeeze the adjacent knocking plate 132, thereby causing the knocking plate 132 to rotate together.

[0039] The clockwise rotation of the roller 131 and the protrusion 134 will squeeze the striking plate 132, but because the striking plate 132 is in contact with the inner wall of the crushing box 1, the roller 131 and the protrusion 134 will not rotate clockwise during the upward movement of the circular scraper 7. When the circular scraper 7 moves upward, the roller 131 will rotate counterclockwise, thereby causing the protrusion 134 to rotate counterclockwise. The counterclockwise rotation of the protrusion 134 will squeeze the striking plate 132, causing the striking plate 132 to rotate clockwise. At this time, the torsion spring 133 is deformed, and the protrusion 134 will separate from the striking plate 132 during the counterclockwise rotation. The protrusion 134 no longer squeezes the knocking plate 132, and the torsion spring 133 recovers, thereby causing the knocking plate 132 to rotate counterclockwise to recover. The knocking plate 132 rotates counterclockwise to knock the inner wall of the crushing box 1, thereby causing the inner wall of the crushing box 1 to vibrate, so that the Chinese medicinal materials remaining on the inner wall of the crushing box 1 can fall off, and the roller 131 and the protrusion 134 continue to rotate counterclockwise, and the next protrusion 134 will squeeze the knocking plate 132 again. Similarly, the inner wall of the crushing box 1 can be knocked multiple times at intervals, so that the Chinese medicinal materials remaining on the inner wall of the crushing box 1 can be fully dropped, and the Chinese medicinal materials remaining in the crushing box 1 can be cleaned.

[0040] refer to Figure 12-14 , and also includes an intermittent feeding mechanism, which includes a blocking plate 141, a rotating ring 142, an extrusion plate 143, a coil spring 144 and an extrusion block 145. The lower part of the feeding hopper 2 is slidably connected with the blocking plate 141, and a coil spring 144 is fixedly connected between the blocking plate 141 and the crushing box 1. The upper part of the blocking plate 141 is fixedly connected to the extrusion block 145 on the side close to the electric rotating rod 4. The upper part of the electric rotating rod 4 is fixedly connected to the rotating ring 142, and the lower part of the rotating ring 142 is fixedly connected to the extrusion plate 143. The extrusion plate 143 is arranged in an arc shape away from the side of the blocking plate 141. When the extrusion plate 143 rotates with the rotating ring 142, the extrusion plate 143 will squeeze the extrusion block 145, so that the extrusion block 145 and the blocking plate 141 slide together in the direction close to the electric rotating rod 4. For details, refer to Fig.14 .

[0041] When the electric rotating rod 4 rotates, it will drive the rotating ring 142 and the squeezing plate 143 to rotate together. Since the squeezing plate 143 is arranged in an arc shape away from the blocking plate 141, the squeezing plate 143 rotates to squeeze the squeezing block 145, so that the squeezing block 145 moves toward the rotating ring 142, and then the blocking plate 141 also moves toward the rotating ring 142. At this time, the coil spring 144 is compressed, and the blocking plate 141 no longer blocks the feeding hopper 2, so that the Chinese medicinal materials in the feeding hopper 2 can fall and be broken. In the box 1, the squeezing plate 143 continues to rotate and will disengage from the squeezing block 145. At this time, the coil spring 144 recovers, causing the blocking plate 141 and the squeezing block 145 to move together in a direction away from the rotating ring 142 until they return to their original positions. At this time, the blocking plate 141 continues to block the feeding hopper 2. The squeezing plate 143 rotates and can intermittently drive the blocking plate 141 to move, causing the Chinese medicinal materials in the feeding hopper 2 to be discharged intermittently, thereby avoiding excessive accumulation of Chinese medicinal materials in the crushing box 1, thereby ensuring the crushing quality of the Chinese medicinal materials.
