Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, and in particular to grinding equipment for extracting traditional Chinese medicine. Background Art

[0002] Traditional Chinese medicine is a drug that is collected, processed, and prepared based on the theories of traditional Chinese medicine, explains its mechanism of action, and guides its clinical application. Traditional Chinese medicine mainly comes from natural medicines and their processed products, including botanicals, animal medicines, mineral medicines, and some chemical and biological drugs. Since traditional Chinese medicine is mostly botanical, there is a saying that "all medicines are based on herbs". Medicinal materials need to be ground before use so that their medicinal properties can be better exerted.

[0003] Most of the existing Chinese medicine grinding equipment consists of a stationary grinding tank and a high-speed rotating grinding assembly, and the grinding requirements of different mesh sizes are achieved by changing the distance between the grinding assembly and the grinding tank. Due to the limitation of this structure, it is easy for the grinding tank to have grinding dead corners that cannot be eliminated by the grinding assembly, and the grinding and crushing capacity of the cutter head in the grinding assembly is usually unadjustable. Therefore, during the Chinese medicine grinding process, it is difficult for this type of grinding equipment to make the particle size of the obtained product fully meet the requirements, especially when the Chinese medicine raw materials contain some difficult-to-crush components, which often leads to repeated grinding of all the Chinese medicine raw materials, thereby reducing the grinding efficiency of the Chinese medicine. Summary of the invention

[0004] The present invention provides a grinding device for extracting traditional Chinese medicine, which limits the only discharge path of the raw materials of traditional Chinese medicine through structural improvement, thereby ensuring that the particle size of the final grinding product meets the set standard. In addition, compared with the traditional grinding device, the fixed grinding cavity is replaced by grinding rings with different rotation directions, so there is no grinding dead angle, ensuring the output rate.

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.

[0020] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a grinding device for extracting traditional Chinese medicine comprises: an upper shell 1, wherein a grinding assembly is arranged inside the upper shell 1, and a feed hopper 13 corresponding to the grinding assembly is arranged at the top, and the bottom end of the upper shell 1 is an open structure; the grinding assembly is arranged in multiple layers, and each layer is composed of a grinding ring 2 and a grinding core 3 adapted in the grinding ring 2, and a first transmission gear set is arranged between the grinding core 3 and the grinding ring 2, and the grinding ring 2 and the grinding core 3 of the same layer are rotated in opposite directions by the first transmission gear set; a sieve plate 4, wherein the sieve plate 4 is horizontally clamped to the bottom of the upper shell 1, and the center of the bottom of the sieve plate 4 A driving unit 8 is provided, and a nested shaft group penetrating the sieve plate 4 is provided at the top of the driving unit 8, and the nested shaft group is composed of a solid shaft 6 and a plurality of nested hollow shafts 7, and a second transmission gear group is provided in the driving unit 8, and the nested shaft group makes any two adjacent hollow shafts 7 rotate in opposite directions through the second transmission gear group, and each of the grinding cores 3 is respectively fitted on the corresponding hollow shaft 7 through its own spline; the sieve plate 4 is provided with a penetrating discharge window corresponding to the grinding assembly, and a filter screen 5 is adapted in the discharge window; a collecting trough 9, and the collecting trough 9 is clamped to the bottom of the sieve plate 4 through the top opening.

[0021] Among them, a crushing wheel 12 is provided in the center of the top of the upper shell 1, the top of the crushing wheel 12 cooperates with the upper shell 1 through the shaft head, and the bottom of the crushing wheel 12 is provided with an axis groove 14; the driving unit 8 includes a reduction motor 23, the solid shaft 6 is connected to the output shaft of the reduction motor 23, and the top of the solid shaft 6 cooperates with the axis groove 14 through a spline; the first transmission gear set includes a driving gear 15 arranged at the top of the crushing wheel 12, and a pair of intermediate gears 16 meshing with the driving gear 15 in sequence, and also includes a pair of side shaft gears 17 meshing with each other, any one of the side shaft gears 17 is meshed with the intermediate gear 16 away from the driving gear 15, and the bottom of each side shaft gear 17 is respectively provided with a side shaft 18 extending downward; the outer edge of the top of each grinding ring 2 is respectively provided with a gear ring 19, and any two adjacent gear rings 19 are respectively matched with different side shafts 18 through driven gears 20.

[0022] The second transmission gear set includes a gear pot 21 arranged at the bottom end of the solid shaft 6 and each of the hollow shafts 7, and any adjacent gear pots 21 are meshed with each other through bevel gears 22, and each of the bevel gears 22 is respectively arranged on the inner wall of the driving unit 8.

[0023] The grinding equipment for extracting Chinese medicine is used to crush and grind a variety of Chinese medicine raw materials, and extract the powder after grinding and crushing. When working, the staff puts the Chinese medicine raw materials into the feed hopper 13 and starts the reduction motor 23. The reduction motor 23 drives the solid shaft 6 to rotate, and drives each grinding core 3 and each grinding ring 2 to rotate respectively under the action of the first transmission gear set and the second transmission gear set. At this time, the Chinese medicine raw materials are initially crushed by the crushing wheel 12, fall into the grinding gap between the grinding ring 2 and the grinding core 3 on the top layer, and are initially ground. Then, the Chinese medicine raw materials are ground into coarse particles. The Chinese medicine raw materials are ground step by step by the grinding rings 2 and the grinding cores 3 of each layer in turn, and finally fall into the collection tank 9 through the filter screen 5, thereby completing the grinding of the Chinese medicine raw materials. This structure defines the only discharge path of the Chinese medicine raw materials. Any raw material particles that do not meet the grinding standard in a certain grinding layer cannot fall further due to the limitation of the gap between the grinding ring 2 and the grinding core 3, thereby ensuring that the particle size of the final grinding product meets the set standard. In addition, compared with the traditional grinding equipment, the fixed grinding chamber is replaced by the grinding ring 2 with different rotation directions, so there is no grinding dead angle, which ensures the output rate.

[0024] Each of the grinding cores 3 is a truncated cone structure and is arranged from small to large from top to bottom. The outer side wall of each grinding core 3 is provided with an outer grinding tooth 10; each of the grinding rings 2 is matched with the corresponding grinding core 3, and the inner side wall of each of the grinding rings 2 is provided with an inner grinding tooth 11 corresponding to the outer grinding tooth 10. The outer grinding teeth 10 and the inner grinding teeth 11 are both helical tooth structures, and the outer grinding teeth 10 and the inner grinding teeth 11 of the same layer are inclined in opposite directions; the outer grinding teeth 10 and the inner grinding teeth 11 of adjacent layers are inclined in opposite directions. In addition, the outer grinding teeth 10 and the inner grinding teeth 11 are arranged from large to small from top to bottom. The discharge window annular structure corresponds to the matching area of ​​the grinding ring 2 and the grinding core 3. A bracket is provided at the bottom of the discharge window, and the filter screen 5 is an annular structure adapted to the discharge window.

[0025] The grinding ring 2 and the grinding core 3 in the grinding device for extracting traditional Chinese medicine are both detachable structures, so the grinding core 3 can be selectively removed, and the filter screens 5 with different mesh sizes can be used to grind powders with different particle sizes.

[0026] In addition, the sieve plate 4 is provided with a wire groove along the radial direction, and the power line of the reduction motor 23 in the drive unit 8 is connected to the external control power supply through the wire groove, so as to realize the control of the rotation direction of the reduction motor 23. During the operation of the reduction motor 23, the solid shaft 6 connected thereto drives the first transmission gear set and the second transmission gear set through the driving gear 15 and the gear basin 21, respectively, so as to realize that each grinding ring 2 and the grinding core 3 rotate in opposite directions respectively, and improve the stirring and grinding effect, and at the same time, with the help of the inclined outer grinding teeth 10 and the inner grinding teeth 11, the raw materials in the grinding process are assisted to turn up and down, so as to achieve the effect of rolling and changing the grinding angle of the raw materials that are difficult to grind. The distribution of the grinding core 3 with a small top and a large bottom not only improves the torque during the initial grinding of the raw materials of traditional Chinese medicine, but also provides a larger grinding area for the final powder grinding process, so its working efficiency is higher.

[0027] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
