Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine grinding and processing technology, and specifically relates to a grinding device, grinding method and traditional Chinese medicine processing technology. Background Technology

[0002] Pinellia ternata, also known as Diwen or Shoutian, is a medicinal plant belonging to the order Araceae, family Araceae, and genus Pinellia. It is used to treat boils and carbuncles, and is also used in veterinary medicine to treat phlegm and throat congestion. It is widely distributed in the Yangtze River basin, Northeast China, North China, and Tibet, growing at altitudes below 2500 meters. To ensure its full utilization, Pinellia ternata is usually ground into powder. The initial processing of Pinellia ternata typically involves grinding it using a grinder.

[0003] In existing grinding machines, to ensure grinding efficiency, the pinellia is filtered and screened after one grinding. After grinding, there are fibrous fragments of pinellia that are not completely ground into powder. Subsequent grinding work is more complicated. Usually, the fragments that are not ground into powder are processed in other ways. The pinellia is not fully ground and utilized, resulting in waste and reduced grinding efficiency. After the equipment filters the pinellia, some pinellia powder remains on the filter screen, which is also wasteful and affects the next grinding operation of the sieve plate. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the problems in related technologies, this invention proposes a grinding device, grinding method, and traditional Chinese medicine processing technology. It features the ability to continue grinding unfiltered Pinellia ternata, ensuring it passes the final screening, thus increasing the grinding effect, reducing processing time for unfiltered Pinellia ternata, and improving grinding efficiency. It also cleans residual Pinellia ternata powder from the filter screen, preventing excessive powder residue and waste, and avoiding impact on subsequent grinding operations. This invention improves equipment applicability and solves the technical problems of insufficient grinding and utilization of fibrous Pinellia ternata fragments, resulting in waste, reduced grinding efficiency, and residual Pinellia ternata powder on the filter screen, which affects subsequent grinding operations.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a grinding device, a grinding method, and a traditional Chinese medicine processing technology, which have the following beneficial effects:

[0020] 1. The grinding column rotates and moves downward, causing the straight-toothed rack to move downward, which in turn drives the rotating support plate to rotate and fit against the filter screen plate. The grinding column continues to move downward to grind the Pinellia ternata on the filter screen plate. After grinding, the grinding column moves upward, causing the straight-toothed rack to move upward and drive the rotating support plate to rotate to a vertical position. The ground Pinellia ternata passes through the filter screen plate and enters the collection box. The Pinellia ternata that does not pass through remains on the filter screen plate. The grinding column moves downward again, repeating the above work to continue grinding the Pinellia ternata that does not pass through the filter, so that it finally passes through the filter. This increases the grinding effect of Pinellia ternata, reduces the processing time of the Pinellia ternata that does not pass through the filter, and improves the efficiency of the grinding work.

[0021] 2. The lifting hydraulic cylinder drives the grinding column to move downwards until it contacts the accumulated Pinellia ternata at the bottom of the grinding column. The lifting cylinder drives the fixed plate to move, which in turn moves the crushing blade downwards out of the cavity. The crushing blade rotates with the grinding column to initially cut and crush the Pinellia ternata. Using the crushing blade to initially crush the Pinellia ternata reduces the difficulty of grinding the Pinellia ternata by the grinding column and improves the extrusion and grinding effect of the grinding column.

[0022] 3. When grinding is finished, the cleaning cylinder drives the lifting baffle to move upward along the lifting groove, and the cleaning electric push rod drives the mounting plate to move, which in turn moves the cleaning plate into the grinding barrel. When the cleaning motor moves to the center position of the filter screen plate, the cleaning motor drives the cleaning plate to rotate. The cleaning plate sweeps the residual Pinellia powder on the filter screen plate, allowing the powder to enter the collection box through the filter holes. This prevents excessive Pinellia powder residue on the filter screen plate, which would cause waste and affect the next grinding operation, thus improving the applicability of the equipment.

Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0038] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0039] Please see Figure 1-10 As shown, the present invention is a grinding device, including a grinding barrel 1, a collection box 2 disposed below the grinding barrel 1, a filter screen plate 3 disposed at the bottom of the grinding barrel 1, and a grinding assembly 4 disposed inside the grinding barrel 1.

[0040] The grinding column 401 is rotatable and can move vertically to contact the top of the filter screen plate 3;

[0041] In use, the Pinellia ternata to be ground is poured into the grinding bucket 1, where it accumulates on the filter screen plate 3. The grinding column 401 rotates and moves downward, causing the connecting plate 402 and connecting rod 403 to move downward. The connecting rod 403 then moves the spur rack 404 downward, which in turn drives the rotating gear 405 to rotate. The rotating gear 405 then drives the rotating support plate 406 to rotate and fit against the filter screen plate 3 for support. The grinding column 401 continues to move downward, grinding the Pinellia ternata on the filter screen plate 3. After grinding, the grinding column 401 moves upward, causing the straight toothed rack 404 to move upward, which in turn drives the rotating gear 405 to rotate. The rotating gear 405 drives the rotating support plate 406 to rotate to a vertical position. The ground Pinellia ternata enters the collection box 2 through the filter sieve plate 3. The Pinellia ternata that does not pass through the filter sieve plate 3 remains on the filter sieve plate 3. The grinding column 401 moves downward again, and the above work is repeated to continue grinding the Pinellia ternata that does not pass through the sieve until it finally passes through the sieve. This increases the grinding effect of Pinellia ternata, reduces the processing time of the Pinellia ternata that does not pass through the sieve, and improves the efficiency of the grinding work.

[0043] In use, the grinding motor 413 drives the transmission gear 412 to rotate the grinding ring 411, which in turn drives the lifting hydraulic cylinder 410 to rotate. The lifting hydraulic cylinder 410 drives the grinding column 401 to move downward until the bottom of the grinding column 401 contacts the accumulated Pinellia ternata. The lifting cylinder 409 drives the fixing plate 407 to move, which in turn moves the crushing blade 408 downward out of the cavity. The crushing blade 408 rotates with the grinding column 401 to initially cut and crush the Pinellia ternata. After crushing, the lifting cylinder 409 drives the fixing plate 407 to move, which in turn moves the crushing blade 408 upward until the bottom of the blade is level with the grinding column 401. The lifting hydraulic cylinder 410 drives the grinding column 401 to move downward to grind the Pinellia ternata. The crushing blade 408 is used to initially crush the Pinellia ternata, improving the crushing effect of the grinding column 401.
