Detailed implementation manners

[0020] The following will cooperate with the drawings and embodiments to elaborate in detail on the implementation manners of the present application, so as to fully understand the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects and implement accordingly.

[0021] As Figure 1 - Figure 4As shown, the medicinal material crushing device provided in this embodiment includes a hopper 2, a crushing structure 3 and a filter plate 6 installed on a crusher 1. A feed box 4 is fixed on one side of the crusher 1. A material port 5 is provided between the crusher 1 and the feed box 4. A feed mechanism is provided inside the feed box 4. The feed box 4 is hollow inside and a maintenance shell is detachably installed on its outer surface. The feed mechanism includes a hydraulic telescopic rod 7 and a feed plate 8 installed inside the feed box 4 and an elastic structure installed between the hydraulic telescopic rod 7 and the feed plate 8. The elastic structure includes a connecting plate 10 fixed on the output end of the hydraulic telescopic rod 7, a first return spring 11 fixed on the lower surface of the feed plate 8, and a first guide rod 12. The bottom end of the first return spring 11 is fixed to the upper surface of the connecting plate 10, and the first guide rod 12 runs through the inside of the connecting plate 10. The first return spring 11 surrounds the outside of the first guide rod 12. The output distance of the hydraulic telescopic rod 7 is adapted to the height of the top material port 5. The number of the elastic structures is two, and the two elastic structures are symmetrically arranged.

[0022] Specifically, there are two material ports 5, and the two material ports 5 are distributed up and down. When the feed plate 8 is not raised or lowered, it is matched with the bottom material port 5. Two baffles 29 symmetrically distributed and arranged in an eight-shaped shape are installed on the upper surface of the feed plate 8. A swinging member is installed on one side of the feed plate 8; the swinging member includes a connecting shaft 13 that rotates on the left side of the feed plate 8 and passes through the inside of the second sliding port 25, an eccentric wheel 14 fixed to the outer surface of the connecting shaft 13, and a transmission gear 15. A first rack 16 meshing with the transmission gear 15 is fixed on the side of the feed box 4 away from the crusher 1. The outer shape of the feed plate 8 is set in an inclined shape, and the side of the feed plate 8 away from the material port 5 is at a high position. The two material ports 5 are matched with the size of the feed plate 8. Since the feed plate 8 is set in an inclined shape, the two sets of baffles 29 are used to limit the material so that the material approaches the material port 5, thereby entering the crusher 1 for secondary crushing. This design allows the material to be limited and guided by the stop bar 29 during the feeding process, so that it can more smoothly approach the material port 5. This optimized feeding process helps to reduce the accumulation and retention of materials in the feeding box 4 and improve the feeding efficiency.

[0023] When the present embodiment is in use, the hydraulic telescopic rod 7 drives the feeding plate 8 to move upward, and the sealing plate 9 is driven to move upward by the same-pole cooperation between the first magnetic block 17 and the second magnetic block 18, so as to cover the bottom material opening 5. When the feeding plate 8 is in the process of rising, when it reaches the top material opening 5, the transmission gear 15 will mesh with the first rack 16 and drive the eccentric wheel 14 to rotate through the connecting shaft 13. The rotation of the eccentric wheel 14 cooperates with the installation of the first return spring 11 and the first guide rod 12 to drive the feeding plate 8 to shake. The limiting function of the two sets of baffles 29 allows the material to approach the material opening 5, thereby entering the crusher 1 for secondary crushing.

[0024] For better feeding, such as Figure 2 -Figure 4 , Figure 6 and Figure 7 As shown in the figure, a shielding structure used in conjunction with the feeding mechanism is arranged inside the material port 5; the shielding structure includes a sealing plate 9 slidably arranged inside the material port 5, a second magnetic block 18 is fixed to the outer surface of the sealing plate 9, and a first magnetic block 17 with the same polarity as the second magnetic block 18 is fixed to the lower surface of the feeding plate 8; through the principle of the same polarity repulsion between the first magnetic block 17 and the second magnetic block 18, when the feeding plate 8 approaches the material port 5, the magnetic repulsion force will push the sealing plate 9 to slide upward and open the material port 5, thereby realizing automatic feeding. This design does not require additional mechanical structures or manual operations, simplifies the feeding process and improves efficiency. Figure 3 and Figure 4 As shown, a receiving groove 19 connected to the bottom material port 5 is provided inside the feeding box 4, and a first sliding opening 20 and a second sliding opening 25 are provided inside the feeding box 4, wherein the first sliding opening 20 and the second sliding opening 25 are located on the left and right sides of the feeding box 4, and the first sliding opening 20 is connected to the receiving groove 19.

[0025] It is worth mentioning that the timely opening and closing of the sealing plate 9, the tilting setting of the feeding plate 8 and the cooperation of the blocking bar 29 together reduce the risk of material accumulation and blockage at the material port 5. This helps to maintain the smoothness and continuity of the feeding process and improve the operating efficiency of the crusher 1. The shielding structure set inside the material port 5 significantly improves the overall performance and operating efficiency of the medicinal material crushing device by improving the sealing performance, automatically controlling the feeding, enhancing the stability and accuracy of the feeding, and reducing the material blockage.

[0026] Specifically, Figure 4 , Figure 6 and Figure 7 As shown, the sealing plate 9 is slidably arranged in the receiving groove 19, and a sealing gasket 24 is fixed on the top of the sealing plate 9. The sliding arrangement of the sealing plate 9 in the material port 5 and the sealing gasket 24 fixed thereon jointly ensure the sealing of the material port 5 during the feeding process. This can effectively prevent the material from leaking out of the material port 5 during the feeding process, and maintain the cleanliness of the inside of the crusher 1 and the integrity of the material. A second guide rod 21 and a second return spring 22 are fixed on the inner bottom wall of the receiving groove 19, the top side of the second return spring 22 is fixed to the lower surface of the sealing plate 9, an extension groove 23 is opened on the bottom side of the sealing plate 9, and the top end of the second guide rod 21 extends into the extension groove 23. The sliding arrangement of the sealing plate 9 and the cooperation of the second guide rod 21 and the second return spring 22 enable the sealing plate 9 to remain stable and accurate when opening and closing the material port 5.

[0027] In order to improve the material crushing efficiency, Figure 1 and Figure 7As shown, an extrusion mechanism is provided on the top side of the feed box 4, and a second rack 28 driving the extrusion mechanism is installed on the side wall of the feed plate 8. A baffle 81 for shielding the second slide 25 is fixed on the side of the feed plate 8 away from the material port 5, and a connecting rod extending to the outside of the second slide 25 and fixed to the bottom side of the second rack 28 is bolted to the outer surface of the baffle 81. The baffle 81 is arranged vertically with the feed plate 8, and can shield the material, thereby preventing the material from leaking from the second slide 25. The extrusion mechanism includes a pushing structure 27 and an extrusion plate 26, and the extrusion plate 26 is located above the feed plate 8, and the shape of the extrusion plate 26 is adapted to the feed plate 8. Specifically, the pushing structure 27 includes two symmetrically distributed support seats 2701, a bidirectional lead screw 2702 with bearings installed between the two support seats 2701, and two sliders 2704 threadedly connected to the outer surface of the bidirectional lead screw 2702 and symmetrically arranged. A fixed plate 2703 is fixed to the upper surface of the extrusion plate 26, and a pushing arm 2705 is hinged between the two sliders 2704 and the fixed plate 2703. The extrusion mechanism can pre-compress the material during the feeding process through the design of the pushing structure 27 and the extrusion plate 26. This pre-compression helps the material to be more densely stacked on the feeding plate 8, so that it can be more effectively crushed when entering the crusher 1. Pre-compression can also reduce the bouncing and splashing of the material during the crushing process, further improving the crushing efficiency. The extrusion plate 26 is smaller than the fixed plate 2703, so that the baffle 81 can be better lifted and extended, and the fixed plate 2703 and the feeding box 4 leave a gap for the baffle 81, and the lifting and lowering of the baffle 81 does not affect the downward movement of the extrusion plate 26.

[0028] In addition, the meshing design of the linkage gear 2706 of the extrusion mechanism and the second rack 28 realizes the automatic linkage control of the feed plate 8 and the extrusion mechanism. When the feed plate 8 rises, the second rack 28 moves accordingly and drives the linkage gear 2706 to rotate, thereby driving the bidirectional lead screw 2702 to rotate. This design does not require additional control devices or manual operation, simplifies the operation process and improves the automation of the equipment.

[0029] Among them, the left end of the bidirectional lead screw 2702 is fixed with a linkage gear 2706 meshing with the second rack 28, and a limit rod penetrating the inside of the two sliders 2704 is fixed between the two support seats 2701. The design of the extrusion mechanism has a certain adaptability and can be adjusted according to the type, size and crushing requirements of the material. For example, the descending speed and pressure of the extrusion plate 26 can be controlled by adjusting the rotation speed of the bidirectional lead screw 2702, so as to meet the crushing requirements of different materials. The position of the second rack 28 is adapted to the lifting height of the feed plate 8, so that the lifting and lowering of the feed plate 8 can be better coordinated with the push structure 27.

[0030] In summary, the crushing device can further refine the material through secondary crushing, making its particle size more uniform, thereby improving the crushing efficiency. After the initial crushing, the material may still contain some larger particles or lumps, and these particles or lumps can be further crushed through secondary crushing to achieve finer particle size requirements. Secondary crushing helps to improve the physical and chemical properties of the material. For medicinal materials, the surface area of ​​the crushed material increases, which is conducive to the extraction and separation of effective ingredients and improves the utilization rate of medicinal materials. At the same time, secondary crushing can also destroy the cell structure in the medicinal materials and release more active ingredients. The secondary crushing capacity enables the crusher 1 to handle more types of materials. Moreover, in the process of medicinal material processing, crushing is one of the key process steps. Secondary crushing can ensure that the material meets the required particle size requirements, thereby improving the quality and stability of the product. This is crucial for the subsequent processing and extraction process of medicinal materials, and it is preferred to improve product quality.

[0031] like Figure 1 - Figure 8 As shown, the principle of the medicinal material crushing device provided in this embodiment is as follows: When in use, first, the hydraulic telescopic rod 7 drives the feeding plate 8 to move upward, and the sealing plate 9 is driven to move upward through the first magnetic block 17 and the second magnetic block 18 with the same pole, so as to cover the bottom material opening 5. When the feeding plate 8 is in the process of rising, when it reaches the top material opening 5, the transmission gear 15 will mesh with the first rack 16 and drive the eccentric wheel 14 to rotate through the connecting shaft 13. The rotation of the eccentric wheel 14 cooperates with the installation of the first return spring 11 and the first guide rod 12 to drive the feeding plate 8 to shake. Since the feeding plate 8 is arranged in an inclined shape, the two sets of baffles 29 are used to limit the material, so that the material is close to the material opening 5, thereby entering the crusher 1 for secondary crushing. When the feeding plate 8 moves upward, the two-way lead screw 2702 is driven to rotate through the meshing of the second rack 28 and the linkage gear 2706. Since the threads on the two-way lead screw 2702 are arranged in opposite directions, the two sliders 2704 move relative to each other. The relative movement of the two sliders 2704 drives the extrusion plate 26 to move downward through the push arm 2705, so that it is close to the feeding plate 8, thereby squeezing the medicinal materials, allowing the medicinal materials to better enter the crusher 1 for crushing, thereby improving the crushing efficiency of the medicinal materials.
