Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0021] Referring to Figures 1 - 3 , the present invention provides an energy-saving crushing device for processing traditional Chinese medicine decoction pieces, including a main body 1 of the crushing box. A rotating shaft 2 is rotatably arranged in the main body 1 of the crushing box. A plurality of first crushing knives 3 are fixedly connected to the periphery of the rotating shaft 2. A grinding block 4 is rotatably connected in the main body 1 of the crushing box. A grinding seat 5 corresponding to the grinding block 4 is fixedly connected in the main body 1 of the crushing box. A driving component for controlling the rotation of the rotating shaft 2 and the grinding block 4 and a moving component for driving the rotating shaft 2 to move up and down are installed on the top of the main body 1 of the crushing box. A feeding port 6 is opened on the top of the main body 1 of the crushing box. The bottom of the main body 1 of the crushing box is communicated with a filter box 7 through a connecting pipe. A filter plate 8 is fixedly connected in the filter box 7. A vibration component is installed on the filter plate 8. A discharge port 9 is opened on the side wall of the filter box 7. By driving the rotating shaft 2 to rotate through the driving component, and then driving the first crushing knives 3 to move, the traditional Chinese medicine in the main body 1 of the crushing box can be broken. At the same time, the driving component drives the grinding block 4 to rotate. Through the cooperation of the grinding block 4 and the grinding seat 5, the broken traditional Chinese medicine can be ground to make it fully crushed. The driving component in the present invention can drive the moving component to move, and then drive the rotating shaft 2 to move up and down, so that the first crushing knives 3 move up and down during the circular motion along with the rotating shaft 2, and can fully break the traditional Chinese medicine in the main body 1 of the crushing box. The vibration component can increase the vibration of the filter plate 8, thereby increasing the filtering efficiency of the filter plate 8 and preventing the filter plate 8 from being blocked.

[0022] Further optimization solution: The driving component includes a driving box 10 fixedly connected to the top of the main body 1 of the crushing box. A mating gear 11 is rotatably connected to the top wall of the main body 1 of the crushing box. The mating gear 11 is located inside the driving box 10. The top end of the rotating shaft 2 penetrates the top wall of the main body 1 of the crushing box and the mating gear 11 and is slidably engaged with the mating gear 11 along its axial direction. A driving motor 12 is fixedly connected inside the driving box 10. The output shaft of the driving motor 12 is fixedly connected with a driving gear 13. The driving gear 13 meshes with the mating gear 11. A groove 14 is formed inside the grinding block 4. The bottom end of the rotating shaft 2 is slidably located inside the groove 14. A transmission shaft 15 is rotatably connected inside the main body 1 of the crushing box. The transmission shaft 15 penetrates the rotating shaft 2 and is slidably connected with the rotating shaft 2 along its axial direction. The top end of the transmission shaft 15 is rotatably connected to the top wall of the driving box 10. The transmission shaft 15 is fixedly connected with the grinding block 4. The driving motor 12 drives the driving gear 13 to rotate, and then drives the mating gear 11 to rotate. The mating gear 11 cooperates with the rotating shaft 2 along its axial direction, and can drive the rotating shaft 2 to rotate while not affecting the movement component to drive the rotating shaft 2 to move up and down. Further, vertical grooves are formed along the axial direction on the peripheral side of the rotating shaft 2, and sliding protrusions corresponding to the vertical grooves are formed on the inner side of the mating gear 11. The sliding protrusions are slidably located inside the vertical grooves to achieve sliding fit in the axial direction.

[0023] Further optimization solution: The movement component includes a rotating plate 16 located inside the driving box 10 and fixedly connected to the top end of the rotating shaft 2. The transmission shaft 15 penetrates the rotating plate 16. A lifting plate 17 is slidably connected inside the driving box 10. A through hole 18 is formed in the middle of the lifting plate 17. The rotating shaft 2 penetrates the through hole 18 and there is a gap between the rotating shaft 2 and the inside of the through hole 18. The lifting plate 17 is located on the bottom surface of the rotating plate 16 and is rotatably engaged with the rotating plate 16. A control component for driving the lifting plate 17 to reciprocate is installed inside the driving box 10. By driving the lifting plate 17 to reciprocate through the control component, the rotating plate 16 is driven to move up and down, and then the first crushing knife 3 is driven to move up and down during the rotation along the rotating shaft 2, so as to fully crush the traditional Chinese medicine in the main body 1 of the crushing box.

[0024] For a further optimized solution, the control component includes a moving block 19 located on the top wall of the crushing box main body 1 and slidably connected to the top wall of the crushing box main body 1. An opening is provided on the side wall of the driving box 10, and the moving block 19 is located within the opening. Connecting columns are respectively fixedly connected to the side wall of the moving block 19 and the end face of the driving gear 13. A first connecting plate 20 is rotatably connected between the two connecting columns. A second connecting plate 21 is rotatably connected between the top surface of the moving block 19 and the bottom surface of the lifting plate 17. The driving motor 12 drives the driving gear 13 to rotate. During the rotation of the driving gear 13, the moving block 19 is driven to slide through the first connecting plate 20. Further, the moving block 19 can only perform reciprocating linear motion in the direction away from or close to the driving gear 13. During the movement of the moving block 19, the lifting plate 17 is continuously pushed and pulled through the second connecting plate 21, thereby driving the lifting plate 17 to perform reciprocating motion in the vertical direction.

[0025] For a further optimized solution, a gap is left between the grinding block 4 and the grinding seat 5. The gap between the grinding block 4 and the grinding seat 5 gradually decreases from top to bottom, and the gap between the grinding block 4 and the grinding seat 5 is communicated with the communicating pipe.

[0026] For a further optimized solution, the vibration component includes an installation box 22 located within the filtering box 7 and fixedly connected to the filtering plate 8. The top surface of the installation box 22 is fixedly connected to the bottom wall of the crushing box main body 1. The transmission shaft 15 passes through the bottom wall of the crushing box main body 1, the installation box 22, and the filtering plate 8 and is rotatably connected to the bottom wall of the filtering box 7. A connecting seat 23 is fixedly connected to the circumferential side of the part of the transmission shaft 15 located within the installation box 22. A receiving groove 24 is provided within the connecting seat 23. A sliding plate 25 is slidably connected within the receiving groove 24. A striking block 26 is fixedly connected to the sliding plate 25. The striking block 26 passes through the side wall of the connecting seat 23 and is in contact with the inner wall of the installation box 22. A return spring 27 is fixedly connected between the sliding plate 25 and the side wall of the receiving groove 24. The transmission shaft 15 drives the connecting seat 23 to rotate, and then under the action of centrifugal force, the striking block 26 is thrown out, causing it to collide with the inner wall of the installation box, thereby causing the installation box 22 and the filtering plate 8 to vibrate, and fully screening the traditional Chinese medicine. After the striking block 26 impacts the installation box 22, it returns to its initial position under the combined action of the impact reaction force and the return spring 27, and then is thrown out again due to centrifugal force, continuously applying vibration.

[0027] For a further optimized solution, the filtering plate 8 is inclined, and a waste outlet 28 is provided on the side wall of the filtering box 7. The waste outlet 28 is correspondingly arranged at the lower end of the filtering plate 8.

[0028] For a further optimized solution, a second crushing knife 29 is fixedly connected to the middle of the first crushing knife 3. The second crushing knife 29 is vertically arranged and perpendicular to the first crushing knife 3, and the second crushing knife 29 is located at the top of the gap between the grinding block 4 and the grinding seat 5. A third crushing knife 30 is fixedly connected to the side wall of the main body 1 of the crushing box. There is a gap between the end of the third crushing knife 30 and the first crushing knife 3. By vertically fixing the second crushing knife 29 in the middle of the first crushing knife 3, the traditional Chinese medicine in the main body 1 of the crushing box can be crushed more fully. At the same time, the second crushing knife 29 at the bottom can cut the top of the gap between the grinding block 4 and the grinding seat 5 to prevent the traditional Chinese medicine from accumulating and blocking the gap. The third crushing knife 30 can cut the medicinal materials that have been rotating with the first crushing knife 3 all the time to ensure the full crushing of the traditional Chinese medicine.

[0029] The working process of the present invention: When in use, start the driving motor 12, and then pour the traditional Chinese medicine to be crushed into the feeding port 6. The driving motor 12 drives the driving gear 13 to rotate, and then drives the mating gear 11 to rotate electrically, thereby driving the rotating shaft 2 to rotate, so that the first crushing knife 3 drives the second crushing knife 29 to rotate in the main body 1 of the crushing box to crush the traditional Chinese medicine. At the same time, during the rotation of the driving gear 13, the moving block 19 is driven to move through the first connecting plate 20. In the linear motion of the moving block 19 approaching or departing from the driving gear 13, the lifting plate 17 is driven to reciprocate up and down through the second connecting plate 21, and then drives the rotating plate 16 to move up and down, so that the first crushing knife 3 and the second crushing knife 29 can move up and down during the rotation with the rotating shaft 2 to fully crush the raw materials in the main body 1 of the crushing box.

[0030] The traditional Chinese medicine crushed by the first crushing knife 3 and the second crushing knife 29 moves between the grinding block 4 and the grinding seat 5. The grinding block 4 is driven to rotate by the transmission shaft 15, and the crushed traditional Chinese medicine is fully ground by the gradually decreasing gap, and then falls into the filtering box 7.

[0031] When the crushed traditional Chinese medicine falls on the filter plate 8 in the filtering box 7, the transmission shaft 15 drives the connecting seat 23 to make a circular motion. The striking block 26 is thrown out under the action of centrifugal force and collides with the inner wall of the installation box 22, so as to apply vibration to the installation box 22 and the filter plate 8. Then it is retracted under the action of the impact and the return spring 27, and then thrown out again due to centrifugal force, continuously applying vibration to the filter plate 8 to facilitate the filtering of the traditional Chinese medicine by the filter plate 8. The traditional Chinese medicine passing through the filter plate 8 is collected through the discharge port 9, and the unqualified traditional Chinese medicine is collected through the waste port 28 and poured into the feeding port 6 together with the next batch of traditional Chinese medicine.
