Along the direction from the upper side plate 112 to the lower side plate 114, the projections of the spiral hollow rod body, the first thickening plate 12 and the second thickening plate 13 do not overlap. At least three circular air holes penetrating the inner and outer walls are arranged along the length extension direction of the spiral hollow rod body, and at least three circular air holes are evenly distributed on the spiral hollow rod body.

At least two groups of magnetic attraction members 41 are connected in series, and at least two groups of magnetic attraction members 41 are electrically connected to the driving assembly 55. Since the driving assembly 55 is electrically connected to the controller 54, the magnetic attraction members 41 can be automatically controlled to be energized through the controller 54 and the driving assembly 55, so that the magnetic attraction members 41 have magnetism. The magnetism of the magnetic attraction members 41 can adsorb the grinding balls 23 in the grinding shell 21, so that the grinding balls 23 are away from the side of the grinding shell 21 close to the lower side plate 114, which is convenient for subsequent cleaning of the inside of the grinding shell 21 and keeps the inside of the grinding shell 21 clean.

[0051] The water-using assembly includes a spray head 42 disposed in the accommodation chamber 101 and a water pump 43 disposed in the upper chamber; the spray head 42 is a side spray type sprinkler head, the material of which can be zinc alloy and the model of which can be AW-SPZ1-H1 / 2; there are at least 2 spray heads 42, and at least 2 spray heads 42 are specifically disposed at one end of the accommodation chamber 101 fixedly connected to the middle side plate 115 and are arranged at the position of the vertical angles in the accommodation chamber 101, and at least 2 spray heads 42 all spray towards the inside of the accommodation chamber 101.

[0057] First, an improved traditional Chinese medicine grinding device provided in this embodiment can be powered on with an external power supply, and traditional Chinese medicines can be placed in the grinding cavity.

[0058] Then, the controller 54 starts to control an improved traditional Chinese medicine grinding device provided in this embodiment to start working; that is, the grinding motor 31 controls the grinding shell 21 to start rotating by itself through the transmission shaft group 32 and the transmission belt group 33, and the grinding balls 23 in the grinding shell 21 start to turn over, thereby pounding and grinding the traditional Chinese medicine materials. At the same time, the stirring rod 22 blows air to promote the turnover of the traditional Chinese medicine materials in the grinding shell 21 and at the same time promotes the discharged of the ground traditional Chinese medicine powder from the grinding shell 21; the filtered traditional Chinese medicine powder falls under gravity and drops between the accommodation cavity 101 and the grinding shell 21; the opening of the accommodation cavity 101 away from the middle side plate 115 can place a storage box to store the traditional Chinese medicine materials.

[0059] Finally, when the improved traditional Chinese medicine grinding device provided in this embodiment that has completed the grinding work needs to be cleaned and automatically stops working, the controller 54 starts to control the cleaning work of the improved traditional Chinese medicine grinding device provided in this embodiment; that is, the magnetic attraction member 41 lifts the grinding balls 23, and at the same time the grinding shell 21 maintains a slow rotation state of being open.

[0085] In the specific operation process, first, the power plug 51 of this embodiment can be externally connected to a power supply for power on, and traditional Chinese medicines can be placed in the grinding cavity.

[0086] Then press the power switch 52 to close the control circuit. Further, set the grinding time and grinding speed on the input component 53. Within 30 s after the setting is completed, the controller 54 starts to control an improved traditional Chinese medicine grinding device provided in this embodiment to start working.

[0088] Through the above - mentioned solution, automatic control can be realized, so that the air pump 24, the water pump 43, the magnetic attracting member 41 and the grinding mechanism 2 can accurately complete various operations, maintain a high level of quality in continuous and uninterrupted operations, and thus improve production efficiency.

The magnetic core is fixedly connected to one side of the middle side plate 115 close to the upper side plate 112, and the wire turns are electrically connected to the magnetic - attracting driving module 552.

[0090] Specifically, the material of the magnetic core can be iron, cobalt or an iron-cobalt-nickel alloy. Its shape is a rectangular block.

The wire turn is formed by multi-layer winding of an insulated wire (such as a copper wire or an aluminum wire), and the surface of the wire is coated with insulating paint to prevent short circuit of the coil after the wire turn and the magnetic attraction driving module 552 are electrified.

[0091] Through the above solution, a strong magnetic field can be generated in the magnetic core after the wire turn is electrified, and then the grinding balls 23 in the grinding shell 21 can be adsorbed, so that the grinding balls 23 are away from the side of the grinding shell 21 close to the lower side plate 114; both the magnetic core and the wire turn are prior arts and are well-known technologies in the art, not the improvement points, nor need to be described in detail. Those skilled in the art can know the above specific structure according to the position and overall structure of this solution, and can clearly know how to implement it.

[0097] Through the above scheme, it can effectively make the traditional Chinese medicine materials enter the grinding shell 21, reduce the splashing or overflow of the unground traditional Chinese medicine during the transfer process; it can simplify the material transfer process, pour the traditional Chinese medicine into the feeding part 141 at one time, reduce the complexity of manual operation, and improve the grinding efficiency; and the funnel-shaped closed design can reduce the exposure of the traditional Chinese medicine during the transfer process and the grinding process, prevent foreign impurities from mixing into the grinding shell 21, and maintain the purity of the traditional Chinese medicine.
