[0005] The application provides a medicinal material grinder, which comprises a feeding box, a grinding cavity and an air chamber which are sequentially connected in communication, a rotating shaft which penetrates the middle and is rotationally connected, the grinding cavity and the air chamber are connected through an annular waist ring, a sleeve ring which is rotationally connected to the outer wall of the waist ring is arranged on the outer wall of the waist ring, a fan blade which blows air towards the outer wall of the grinding cavity is fixed on the sleeve ring, a driving ring which is rotationally connected to the inner wall of the waist ring is attached to the inner wall of the waist ring, the driving ring is fixedly connected to a sleeve which is fixed to the rotating shaft through a connecting rod, permanent magnets which are alternately arranged in two kinds of magnetic poles are arranged in the sleeve ring and the driving ring respectively, and the positions of the opposite magnetic poles of the two kinds of magnetic poles correspond radially and are connected through magnetic force transmission.

[0006] Optionally, an annular water storage layer is arranged in the side wall of the grinding cavity, and a water injection and discharge port which communicates with the water storage layer is arranged on the top and the bottom of the grinding cavity.

[0007] Optionally, a plurality of radially fixed heat dissipation fins are arranged in an annular manner on the outer wall of the grinding cavity.

[0009] Compared with the prior art, the medicinal material grinder provided by the application has the following beneficial effects:

[0010] The rotation of the rotating shaft in the crushing process is used. The drive ring arranged in the waist ring drives the sleeve ring and the fan blade arranged outside the waist ring to rotate through magnetic transmission, and the outer wall of the crushing cavity is air-cooled. Avoid the friction temperature in the crushing cavity being too high during the crushing process of traditional Chinese medicinal materials, which leads to the volatilization of drug components and affects the efficacy.

DETAILED DESCRIPTION

[0019] ​​To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0020] As shown in Figures 1-4 An embodiment of the present application provides a medicinal material grinder, which comprises a feeding box 1, a crushing cavity 2, and an air chamber 3 connected in sequence, a rotating shaft 5 penetrating through the middle of the feeding box 1, the crushing cavity 2, and the air chamber 3 is rotationally connected, and one end of the rotating shaft 5 is driven by being connected to the output shaft of a motor. A tooth plate 4 is fixed on the inner wall of the crushing cavity 2, and a square blade 6 cooperating with the tooth plate 4 is fixed on the rotating shaft in the crushing cavity 2.

[0021] The crushing cavity 2 and the air chamber 3 are connected through an annular waist ring 8, a sleeve ring 9 rotationally connected to the outer wall of the waist ring 8 is sleeved on the outer wall of the waist ring 8, the inner annular surface of the sleeve ring 9 is attached to or connected to the waist ring 8 through ball sliding. A fan blade 10 blowing air towards the outer wall of the crushing cavity 2 is fixed on the sleeve ring 9, a driving ring 13 rotationally connected to the inner wall of the waist ring 8 is attached to the inner wall of the waist ring 8, and the driving ring 13 is fixedly connected to a sleeve 11 sleeved on the rotating shaft 5 through a connecting rod 12. Permanent magnets of two kinds of magnetic poles arranged alternately are respectively arranged in the sleeve ring 9 and the driving ring 13, the positions of the opposite magnetic poles between the sleeve ring 9 and the driving ring 13 correspond in the radial direction, and the sleeve ring 9 and the driving ring 13 are connected through magnetic force transmission.

[0022] In use, the traditional Chinese medicinal materials enter the crushing cavity 2 through the feeding box 1, the motor drives the square blade 6 to rotate through the rotating shaft 5, and the square blade 6 cooperates with the tooth plate 4 to crush the entering traditional Chinese medicinal materials. While the traditional Chinese medicinal materials are crushed, the rotating shaft 5 drives the driving ring 13 to rotate along the inner wall of the waist ring 8 through the sleeve 11 and the connecting rod 12, the driving ring 13 drives the sleeve ring 9 to rotate through magnetic force transmission, and the sleeve ring 9 drives the fan blade 10 to rotate to blow air to the outer wall of the crushing cavity 2 for cooling and temperature reduction.

[0023] In the embodiment, the rotating shaft 5 rotates in the crushing process, the driving ring 13 arranged in the waist ring 8 drives the sleeve ring 9 and the fan blade 10 sleeved outside the waist ring 8 to rotate through magnetic force transmission, and the outer wall of the crushing cavity 2 is air-cooled and temperature-reduced. The temperature in the crushing cavity 2 is prevented from being too high due to friction in the crushing process, so that the evaporation of medicinal ingredients is avoided to affect the medicinal effect.

[0024] The sleeve ring 9 and the fan blade 10 are driven to rotate by magnetic force between the sleeve ring 9 and the driving ring 13, the driving ring 13 is driven to rotate by the rotating shaft 5, therefore, the rotating speed of the fan blade 10 increases or decreases with the rotating speed of the rotating shaft 5. When the rotating speed of the rotating shaft 5 increases to improve the crushing efficiency, the friction temperature of the crushing cavity 2 further rises, at this time, the rotating speed of the fan blade 10 also rises to improve the heat dissipation speed and the heat dissipation effect. Conversely, when the rotating speed of the rotating shaft 5 decreases, the rotating speed of the fan blade 10 also decreases. The effect of following speed regulation can be achieved.

[0026] The water injection and discharge port 14 can be used to inject heat exchange liquid for cooling in the water storage layer 7, the specific heat capacity of the heat exchange liquid is larger, which can quickly absorb the heat generated by friction in the crushing cavity 2, and the heat is cooled by the fan blade 10 to achieve a better effect of continuously cooling the crushing cavity 2.

[0027] In a possible implementation, a plurality of radial fixed heat dissipation fins 15 are annularly arranged on the outer wall of the crushing cavity 2.

[0028] The heat dissipation fins 15 can effectively increase the heat dissipation area and the contact area with the cold air, improve the heat exchange efficiency of the heat conducted out of the crushing cavity 2, and further improve the heat dissipation and cooling effect.

[0029] In a possible implementation, a wind baffle 16 is inserted and fixed at the connection between the feeding box 1 and the crushing cavity 2.

[0030] The wind baffle 16 is fixed between the feeding box 1 and the crushing cavity 2, which is used to shield the mouth of the feeding box 1 to avoid the influence of the blowing of the fan blade 10 on the normal feeding of the feeding box 1.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
