[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In one embodiment, see Figure 1-Figure 11 A pre-crusher for extracting Chinese medicine comprises a rotating beam 3, a crushing blade 4 is arranged in the middle of the rotating beam 3, guide columns 8 are arranged on both sides of the rotating beam 3, and a sliding plate 9 is slidably connected to the guide column 8. The rotating beam 3 is arranged horizontally, and a high-speed rotating crushing blade 4 is arranged in the middle of the rotating beam 3.

A feeding port 31 of a rectangular structure is arranged in the middle position of the top of the raw material storage tank 30. A feeding drum 32 arranged in a left and right direction is rotatably connected to the middle of the feeding port 31. Feeding notches 33 are arranged on the upper and lower sides of the feeding drum 32. The feeding notches 33 are in an open state. When the raw material is put into the upper feeding notch 33, the feeding drum 32 can be rotated 180°. At this time, the upper feeding notch 33 rotates to a downward state and is located inside the raw material storage tank 30. At this time, the raw material in the feeding notch 33 will fall into the inside of the raw material storage tank 30, thereby achieving the feeding effect.

[0029] The discharge mechanism 11 includes a powder storage tank 13 fixedly connected to the sliding plate 9 below, the side walls on the left and right sides of the powder storage tank 13 are fixedly connected to the two left and right sliding plates 9, and the top of the powder storage tank 13 is in an open state, the powder storage tank 13 and the raw material storage tank 30 have the same outer dimensions, so the powder storage tank 13 and the raw material storage tank 30 can form a complete cylindrical structure when they are close to each other and tightly attached to each other to achieve a sealed effect, and the lower part of the powder storage tank 13 is a conical structure, so that the Chinese medicine stored in the powder storage tank 13 will slide along the inclined surface to the bottom of the powder storage tank 13, and an upwardly protruding cavity is set on the lower surface of the powder storage tank 13, and the cavity is connected to the upper The square conical bottom has a conducting through hole at the intersection, and the upwardly raised cavity is the discharge port 14.

Discharge notches 16 are provided on the upper and lower sides of the discharge drum 15. The discharge notch 16 is in an open state, that is, when the discharge notch 16 is rotated upward, the discharge notch 16 and the through hole above are overlapped, so that the traditional Chinese medicine inside the powder storage tank 13 can slide into the discharge port 14, and when the discharge drum 15 is rotated by an angle, the discharge notch 16 and the through hole are staggered, so that the through hole is blocked, so that the powder storage tank 13 will not have the problem of bottom leakage.

[0030] In one case of this embodiment, the inner wall of the powder storage tank 13 is provided with a block 17, and a screening plate 18 is provided on the block 17 to cooperate with the crushing blade 4. The block 17 is provided on the left and right sides of the inner wall of the powder storage tank 13, and the screening plate 18 is disc-shaped, and the diameter of the screening plate 18 is the same as the inner diameter of the powder storage tank 13, so the screening plate 18 will be blocked by the block 17 after falling into the powder storage tank 13, and the crushed Chinese medicine is filtered through the screening plate 18, so that the crushed powdered Chinese medicine passes through the screening plate 18 and falls to the bottom of the powder storage tank 13, thereby realizing the discharge process.

[0031] In one case of this embodiment, a locking assembly 12 is provided at the end of the guide column 8, and the locking assembly 12 can push the upper sliding plate 9 downward and push the lower sliding plate 9 upward, so that the powder storage tank 13 and the raw material storage tank 30 are tightly attached after the locking assembly 12 presses the sliding plate 9. The locking assembly 12 includes a rotating plate 19 rotatably connected to the end of the guide column 8, and the end of the rotating plate 19 is threadedly connected to a tightening screw 20 that cooperates with the sliding plate 9. A fixing ring 22 is provided on the side of the guide column 8 close to the rotating beam 3, and a return spring 21 is provided between the fixing ring 22 and the sliding plate 9. When the interior of the pulverizer needs to be cleaned, the tightening screw 20 can be loosened and the rotating plate 19 can be rotated to the front-back direction. At this time, the tightening screw 20 is disengaged from the sliding plate 9. At this time, the upper sliding plate 9 is pushed upward by the action of the return spring 21, and the lower sliding plate 9 will slide downward under the action of gravity, that is, the lower return spring 21 is stretched, so that the powder storage tank 13 and the raw material storage tank 30 are separated. At this time, the pulverizer can be cleaned. After the cleaning is completed, the powder storage tank 13 is first pushed upward. The upper surface of the powder storage tank 13 is made to be close to the lower surface of the rotating beam 3, the rotating plate 19 below is rotated to a state parallel to the sliding plate 9, and the tightening screw 20 is tightened, so that the powder storage tank 13 presses against the lower part of the rotating beam 3, and then the raw material storage tank 30 is pressed downward, and the lower part of the raw material storage tank 30 presses against the rotating beam 3, and a clearance gap 34 is set at the left and right ends of the raw material storage tank 30, so that the raw material storage tank 30 can avoid the rotating beam 3 and press against the powder storage tank 13, at this time, the powder storage tank 13 and the raw material storage tank 30 are pressed against each other. A circle of sealing grooves 29 are set at the upper end of the powder storage tank 13, and a sealing ring 35 is set at the bottom of the raw material storage tank 30, so when the raw material storage tank 30 and the powder storage tank 13 press against each other, the sealing ring 35 presses against the sealing groove 29, thereby improving the sealing performance.

[0032] In one case of this embodiment, the two ends of the feed port 31 are provided with first bearing seats 42 fixedly connected to the outer wall of the raw material storage tank 30, the first bearing seats 42 are rotatably connected to the first shaft 41 fixedly connected to the feed drum 32, the first shaft 41 is provided with a first rotating block 40 at one end away from the feed drum 32, the middle part of the first rotating block 40 is slidably connected to a flip rod 39, the end of the flip rod 39 is provided with a ball head 38, and the raw material storage tank 30 is provided with a slot 37 that cooperates with the ball head 38. Figure 3 state, at this time, the flip rod 39 is in the up and down direction, so each time the feed drum 32 flips 180°, the ball head 38 will fall into the slot 37 to achieve a limiting effect, thereby preventing the feed drum 32 from shaking back and forth and achieving a flip limiting effect.

[0033] In one case of this embodiment, the two ends of the discharge port 14 are provided with second bearing seats 27 fixedly connected to the outer wall of the powder storage tank 13, the second bearing seats 27 are rotatably connected to the second shaft 28 fixedly connected to the discharge drum 15, the second shaft 28 is provided with a second rotating block 24 at one end away from the discharge drum 15, the second rotating block 24 is rotatably connected to a U-shaped rotating frame 23, the middle of the rotating frame 23 is provided with a hanging rod 25, and the end of the hanging rod 25 is provided with a counterweight head 26. Under the action of the counterweight head 26, the hanging rod 25 is always in a downward state, and the hanging rod 25 is always in a downward state. Figure 3 In this state, the hanging rod 25 is in a vertical state, so each time the discharging drum 15 flips 180°, the hanging rod 25 will be in a downward state under the action of the counterweight head 26, and still play a limiting effect, so that the discharging drum 15 will not shake autonomously after rotating 180°.

[0034] In one case of the present embodiment, the middle part of the rotating beam 3 is rotatably connected with a main shaft 43, and the main shaft 43 is vertically arranged in the middle part of the rotating beam 3. Crushing blades 4 are arranged on the upper and lower sides of the main shaft 43, so the main shaft 43 can simultaneously drive the crushing blades 4 on the upper and lower sides to rotate at high speed, and the crushing blades 4 can be arranged in an inclined state, so that the crushing blades 4 can generate downward airflow when rotating, so that the internal Chinese medicine will move downward and gather in the middle part of the screening plate 18, so that the Chinese medicine and the crushing blades 4 can be contacted to achieve the crushing process, and it is also convenient for the crushed Chinese medicine to pass through the screening plate 18, and a top head 49 is arranged at the lower end of the main shaft 43, and the top head 49 will press the screening plate 18 tightly, so that the screening plate 18 can press the stopper 17, so as to achieve the effect of fixing the screening plate 18, and the screening plate 18 is also arranged in a state of being concave in the middle, so that the Chinese medicine will gather toward the middle part of the screening plate 18, so that the gathered Chinese medicine can contact the crushing blades 4 more stably to avoid uneven crushing. A fixed block 47 is set on the right side of the upper surface of the rotating beam 3, and the middle part of the fixed block 47 is rotatably connected to the transmission shaft 46 set in the left and right directions. The clearance gap 34 on the right side of the raw material storage tank 30 is also set to meet the size of this fixed block 47, so that the clearance gap 34 can avoid the fixed block 47, ensuring the closed treatment of the raw material storage tank 30 and the powder storage tank 13. A driving motor 48 is set on the right side of the upper surface of the rotating beam 3, and the output shaft of the driving motor 48 is fixedly connected to the right end of the transmission shaft 46. A first bevel gear 45 is set on the left end of the transmission shaft 46. The first bevel gear 45 is meshed with a second bevel gear 44 fixedly connected to the main shaft 43. Therefore, the driving motor 48 can rotate the main shaft 43 through gear transmission to achieve crushing.

[0035] In one case of this embodiment, the two ends of the rotating beam 3 are fixedly connected with the rotating seat 2, the rotating seat 2 is rotatably connected to the end of the support frame 1, the end of the rotating seat 2 is fixedly connected to one end of the rotating plate 7, the other end of the rotating plate 7 is slidably connected to the limiting rod 6, and the support frame 1 is provided with a limiting hole 5 that cooperates with the limiting rod 6. The entire crusher is supported by the support frame 1, and the limiting rod 6 on the right side can limit the rotation of the rotating beam 3 after being inserted into the limiting hole 5, so that stability is maintained during the loading and unloading process.

[0036] During the implementation of this embodiment, the support frame 1 is firstly stably placed on the ground. In order to ensure stability during the crushing process, the bottom of the support frame 1 can also be fixedly connected to the ground by bolt connection.

[0037] For Chinese medicine sample loading, push the powder storage tank 13 upward, and tighten the lower tightening screw 20 against the sliding plate 9, so that the upper end of the powder storage tank 13 presses against the lower surface of the rotating beam 3, press the raw material storage tank 30 downward, so that the raw material storage tank 30 presses against the powder storage tank 13, and tighten the upper tightening screw 20 to press against the sliding plate 9. At this time, the rotating plate 7 can be rotated to a vertical state, and the limiting rod 6 is inserted into the limiting hole 5. At this time, the preparation work is completed, and a part of the Chinese medicine to be crushed is poured into the upper feeding gap 33, pull out the flip rod 39 upward to disengage the ball head 38 from the slot 37, and then rotate the feeding drum 32 180° to rotate the feeding notch 33 filled with Chinese medicinal materials to a facing state, and a triangular protrusion 36 is provided on the inner side wall of the feeding notch 33, so that the triangular protrusion 36 can have a certain blocking effect during the rotation of the feeding notch 33, so that after the feeding notch 33 is rotated to the inside of the raw material storage tank 30, the feeding notch 33 is in a downward state, and the Chinese medicinal materials are now completed.

[0038] The Chinese medicine is crushed and the drive motor 48 is started. The drive motor 48 causes the crushing blade 4 to start rotating at a high speed through a gear transmission. The crushing blade 4 crushes the Chinese medicine raw materials above the screening plate 18. The Chinese medicine crushed into powder will pass through the screening plate 18 and fall to the bottom and finally slide into the discharge gap 16 below. At this time, the hanging rod 25 can be rotated to a horizontal state, and the discharge drum 15 can be rotated 180 degrees, so that the discharge gap 16 storing the powdered Chinese medicine can be rotated to a downward state, realizing the unloading process, and the discharge gap 16 is set The internal space is designed to be large and the opening is small, so that there will be no leakage of traditional Chinese medicine during the flipping process, and the material will not be discharged only when the discharge notch 16 is rotated to a state close to being completely downward. During the entire crushing process, the feeding and discharging operations can be continuously performed, so that the grinder can continue to work, and when the grinder needs to stop after working for a period of time, the limit rod 6 can be pulled out at this time, and the powder storage tank 13 and the raw material storage tank 30 that are tightly attached to each other can be shaken back and forth, so that the traditional Chinese medicine that has not yet been completely crushed can better contact with the crushing blades 4, thereby improving the crushing effect.

[0039] For cleaning of the grinder, stop the driving motor 48, loosen the tightening screw 20, and rotate the rotating plate 19 to the front-to-back direction. At this time, the powder storage tank 13 and the raw material storage tank 30 are disengaged, and the screening plate 18 can be taken out and cleaned. The inside of the powder storage tank 13 and the raw material storage tank 30 can also be cleaned, and the damaged crushing blade 4 can also be replaced, thereby reducing the difficulty of maintenance of the entire grinder.

[0040] The present invention is applicable to a pre-crusher for extracting traditional Chinese medicine. By arranging a feeding drum 32 with a feeding notch 33 and a discharging drum 15 with a discharging notch 16, the discharging and feeding actions can be continuously performed when the crusher is performing a crushing operation, so that the crusher can continuously operate and improve the working efficiency. Moreover, since the discharging drum 15 and the feeding drum 32 are both cylindrical, no leakage problem will occur during the rotation process, which effectively ensures the airtightness of the entire crusher. Moreover, the crushing blades 4 are designed to be in an inclined state so that the airflow continuously flows downward. Therefore, even if a gap appears in the feeding drum 32 when it rotates, the airflow will generate negative pressure in the gap to avoid powder leakage from above. Moreover, the discharging notch 16 below is an upwardly protruding cavity, and the contact area between the discharging notch 16 and the discharging drum 15 is large, which avoids the problem of leakage.

[0041] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
