[0035] A partition 125 is provided inside the cylinder 12, the driving motor 2 is installed at the bottom of the cylinder 12, the transmission shaft 21 is installed on the output shaft of the driving motor 2, the transmission shaft 21 passes through the partition 125, and a rotating sealing connection is formed between the transmission shaft 21 and the partition 125; a plurality of crushing pieces 22 are provided on the transmission shaft 21 above the partition 125, a sliding sealing connection is formed between the extension piece 221 and the crushing piece 22, a telescopic chamber 222 is formed between the extension piece 221 and the crushing piece 22, the extension piece 221 and the crushing piece 22 are connected by a spring, a heat-conducting medium 223 is provided in the telescopic chamber 222, and the heat-conducting medium 223 is made of a material that expands when heated, and multiple groups of metal plates 224 are provided on the extension piece 221 and the crushing piece 22 close to the telescopic chamber 222, the multiple groups of metal plates 224 are in contact with the heat-conducting medium 223, and the multiple groups of metal plates 224 are located in the magnetic field of the coil 13.

[0036] The coil 13 and the sleeve 122 are located on the outside of the plurality of crushing pieces 22, and the coil 13 is arranged on the cylinder 12 and the sleeve 122; in the horizontal direction, a pole 131 is arranged on the outside of each turn of the coil 13, and each pole 131 and both ends of the coil 13 are electrically connected to the control system through a wire, and pressure sensors are installed on the plurality of crushing pieces 22, and the pressure sensors are electrically connected to the control system, and the control system obtains the depth of the medicinal material through a plurality of pressure sensors.

[0037] The distance between the crushing piece 22 and the extension piece 221 is designed to be adjustable. The driving motor 2 drives the crushing piece 22 to rotate through the transmission shaft 21. The crushing piece 22 crushes the Chinese medicinal materials. The pressure sensor on the crushing piece 22 hits the Chinese medicinal materials. When the data of the pressure sensor becomes larger, the control system determines that there are Chinese medicinal materials at this depth. When the data of the pressure sensor is almost unchanged, the control system determines that there are no Chinese medicinal materials at this depth. Since a plurality of crushing pieces 22 are arranged on the transmission shaft 21, and each crushing piece 22 is installed with a pressure sensor, the control system obtains the depth of the Chinese medicinal materials by calculation and feeds back the depth data to the control system.

[0038] When the control system obtains the depth data of the Chinese medicinal material, the control system controls the corresponding two groups of poles 131 to connect to the circuit according to the depth data, so that the distance between the two groups of poles 131 is greater than or equal to the depth of the Chinese medicinal material, and the current enters from the upper pole 131, flows through the effective turns of the coil 13 (the turns of the coil 13 between the poles 131 on both sides), and then flows out from the lower pole 131 to the control system. The coil 13 within the effective turns generates a magnetic field, and the driving motor 2 drives a plurality of crushing pieces 22 to rotate through the transmission shaft 21, and the crushing pieces 22 drive the metal plates 224 and The extension piece 221 rotates synchronously, and the metal plate 224 cuts the magnetic flux lines in the magnetic field of the coil 13. Current is generated in the metal plate 224 and heat is generated. The metal plate 224 transfers the heat to the heat-conducting medium 223. The heat-conducting medium 223 expands after absorbing the heat, thereby increasing the pressure in the telescopic chamber 222. The heat-conducting medium 223 pushes the extension piece 221 to move outward from the crushing piece 22. The extension piece 221 stretches the spring at the same time, and the distance from the outermost side of the extension piece 221 to the center of the transmission shaft 21 becomes larger. At this time, the crushing piece 22 and the extension piece 221 simultaneously crush the Chinese medicinal materials.

[0039] The staff flexibly adjusts the distance between the crushing piece 22 and the extension piece 221 according to different types of Chinese medicinal materials to meet different usage requirements. When the size of the Chinese medicinal materials is large, the distance between the crushing piece 22 and the extension piece 221 is adjusted so that the distance between the outermost side of the extension piece 221 and the sleeve 122 is larger than the size of the Chinese medicinal materials, thereby preventing blockage between the crushing piece 22 or the extension piece 221 and the Chinese medicinal materials during the crushing process, thereby helping to reduce the risk of blockage of the Chinese medicinal materials during the crushing process and ensuring the continuous and stable operation of the grinder.

[0040] The distance between the crushing piece 22 and the extension piece 221 is determined by the magnitude of the current passed through the coil 13. When the speed of the driving motor 2 is constant, the greater the current passed through the coil 13, the greater the magnetic field strength generated by the coil 13, the greater the current generated by the metal plate 224 cutting the magnetic flux lines, the greater the heat generated by the metal plate 224, the greater the degree of expansion of the heat-conducting medium 223, the greater the distance that the heat-conducting medium 223 pushes the extension piece 221, and the more the extension piece 221 extends outward from the crushing piece 22, which can meet the needs of different types of Chinese medicinal materials.

[0041] The reciprocating plate 14 is located above the coil 13, and a sliding sealing connection is formed between the reciprocating plate 14 and the inner wall of the cylinder 12 and the outer wall of the sleeve 122.

[0042] A filter plate 231 is slidably mounted on the transmission shaft 21, and a plurality of fan-shaped grooves are arranged on the filter plate 231. A fixing plate 234 is arranged on the filter plate 231 near the fan-shaped groove. The fan-shaped groove and the filter plate 231 are concentrically arranged. A plurality of groups of filter screens 23 are arranged. The plurality of groups of filter screens 23 are respectively arranged in the fan-shaped grooves. The filter screens 23 are mounted on the filter plate 231. A plurality of sliding shafts 232 are arranged on the outer side of the filter plate 231. A plurality of sliding grooves 124 are arranged on the inner wall of the cylinder 12 opposite to the filter plate 231. The sliding shafts 232 are respectively inserted into a plurality of sliding grooves 124, a reset tension spring is connected between the cylinder 12 and the sliding shaft 232, the reset tension spring is located in the sliding groove 124, and a plurality of protrusions are arranged on the lower side of the filter plate 231; the cam 25 is mounted on the transmission shaft 21, and a plurality of protrusions are arranged on the upper side of the cam 25, and a plurality of protrusions on the lower side of the filter plate 231 abut against a plurality of protrusions on the upper side of the cam 25; the cleaning plate 24 is rotatably mounted on the filter plate 231 through a bearing, and a plurality of groups of cross plates 241 are arranged on the outer side of the cleaning plate 24, and the cross plates 241 are arranged on the outer side of the cleaning plate 24. A shielding film 242 is connected between the plate 241 and the fixed plate 234. The shielding film 242 forms a sliding sealing connection with the filter plate 231 on both sides. The shielding film 242 is made of a flexible material. The shielding film 242 shields the filter screen 23 in the fan-shaped groove. A first spring 233 is connected between the horizontal plate 241 and the fixed plate 234. The first spring 233 is located below the shielding film 242. The first spring 233 is electrically connected to the control system; the aperture of the filter screen 23 gradually increases from one side of the fan-shaped groove to the other side. Angle sensor, the angle sensor is electrically connected to the control system, the angle sensor is used to monitor the rotation angle of the horizontal plate 241, the multiple groups of horizontal plates 241 are hollow inside, brushes 244 are arranged on the lower side of the multiple groups of horizontal plates 241, and jet holes 243 are arranged on one side of the multiple groups of horizontal plates 241. The jet holes 243 are connected to the inside of the horizontal plates 241, the jet holes 243 are directly opposite to the filter screen 23, the brushes 244 are in contact with the filter screen 23, the inside of the horizontal plate 241 is connected to the vacuum pump (not shown in the figure) through a pipeline, and the vacuum pump is installed on the base plate 11.

[0043] A telescopic plate is connected between the inner wall of the cylinder 12 near the upper end of the sliding groove 124 and the sliding shaft 232. The telescopic plate is a telescopic structure. The telescopic plate (not shown in the figure) is slidably connected to the cylinder 12. The telescopic plate blocks the sliding groove 124 and the reset spring to prevent Chinese medicinal material powder from entering.

[0044] Working principle: Press the start button on the control panel 1 to start the crusher. The staff sets the required maximum filter aperture through the control panel 1. The control system adjusts the current passed into the first spring 233 according to the maximum filter aperture. After the first spring 233 is energized, a mutually attractive magnetic field is generated between each turn of the first spring 233. The magnetic field compresses the first spring 233, causing the first spring 233 to shorten as a whole. The first spring 233 pulls the cross plate 241 to rotate a certain angle along the center of the filter plate 231. The cross plate 241 drives the shielding film 242 to gradually shrink. The shielding film 242 gradually shrinks and cannot completely block the filter 23, so that the position on the filter 23 corresponding to the maximum filter aperture is not blocked by the shielding film 242, thereby realizing the particle size adjustment of the Chinese medicinal materials after crushing and filtering. The position on the filter 23 that is not blocked by the shielding film 242 is the effective filtering range.

[0045] The effective filtering range of the filter 23 is related to the contraction degree of the shielding film 242, and the expansion and contraction degree of the shielding film 242 is related to the rotation angle of the horizontal plate 241, and the rotation angle of the horizontal plate 241 is related to the contraction degree of the first spring 233. The expansion and contraction degree of the first spring 233 is determined by the magnitude of the current passed through. Therefore, the control system adjusts the effective filtering range of the filter 23 by adjusting the magnitude of the current passed through the first spring 233; the greater the current passed through the first spring 233, the greater the contraction degree of the first spring 233, the shorter the first spring 233 as a whole, the greater the angle at which the first spring 233 pulls the horizontal plate 241 to rotate, the more the horizontal plate 241 drives the shielding film 242 to contract, and the larger the effective filtering range of the filter 23.

[0046] After the effective filtering range of the filter 23 is adjusted, the buzzer in the control panel 1 alarms to remind the staff to put in the Chinese medicinal materials. The staff removes the cover tube 121 and puts the Chinese medicinal materials into the sleeve 122. The control system controls the drive motor 2 to drive the transmission shaft 21 to rotate, and the transmission shaft 21 drives a plurality of crushing pieces 22 and a cam 25 to rotate. The plurality of crushing pieces 22 rotate to crush the Chinese medicinal materials into powder. Smaller powder passes through the filter 23 within the effective filtering range and falls on the partition 125. Powder with larger particles continues to be crushed by the crushing pieces 22.

[0047] During the process of crushing the Chinese medicinal materials by the crushing piece 22, the driving motor 2 drives the cam 25 to rotate, and the protrusion on the upper side of the cam 25 rotates accordingly. When the protrusion on the upper side of the cam 25 contacts the protrusion on the lower side of the filter plate 231, the cam 25 pushes the filter plate 231 to move upward, and the sliding shaft 232 on the filter plate 231 slides upward in the sliding groove 124 and compresses the reset spring. The filter screen 23 moves upward following the filter plate 231. After that, the protrusion on the cam 25 does not contact the protrusion on the lower side of the filter plate 231. When the filter screen 23 is moved downward, the return spring 231 is released, and the return spring pushes the filter plate 231 to move downward, and the filter plate 231 drives the filter screen 23 to move downward. As the cam 25 continues to rotate, the protrusion on the upper side of the cam 25 contacts the protrusion on the lower side of the filter plate 231 alternately, and the filter plate 231 continuously drives the filter screen 23 to vibrate up and down, so that the crushed powder cannot block the filter screen 23. At the same time, the vibration of the filter screen 23 can facilitate the powder to pass through the filter screen 23, thereby accelerating the filtering speed of the filter screen 23 for the Chinese medicinal material powder.

[0048] After the Chinese medicinal materials are filtered through the filter net 23, they are deposited on the partition 125. The staff presses the stop button on the control panel 1 to stop the drive motor 2, removes the plug on the discharge port 123, and adjusts the rotating handle so that the cylinder 12 and the bottom plate 11 can rotate. The staff tilts the cylinder 12 to allow the powder on the partition 125 to be discharged through the discharge port 123.

[0049] After the Chinese medicinal materials are taken out, the staff presses the cleaning button on the control panel 1, and the control system continuously energizes and deenergizes the first spring 233. After the first spring 233 is energized, it pulls the horizontal plate 241 to rotate from one side of the filter 23 to the other side, and the brush 244 on the lower side of the horizontal plate 241 brushes the filter 23 at the same time. The vacuum pump works at the same time, and the vacuum pump pressurizes the external air and transports it to the inside of the horizontal plate 241. The pressurized air passes through the inside of the horizontal plate 241 and is sprayed onto the filter 23 from the jet hole 243. The filter 23 is cleaned by the pressurized air, and cooperates with the brush 244 to form a composite cleaning process, thereby improving the cleaning effect of the filter 23.

[0050] When it is necessary to spray cleaning liquid into the cylinder 12 and the sleeve 122, the control system connects the two ends of the coil 13 to the circuit and the electromagnet 141. After the coil 13 is energized, a magnetic field is generated at both ends. The magnetic field and the magnetic field of the electromagnet 141 on the lower side of the reciprocating plate 14 repel each other. Under the action of the repulsive force, the reciprocating plate 14 moves upward, and the pressure of the cleaning liquid between the reciprocating plate 14, the sleeve 122 and the cylinder 12 increases. The control system simultaneously opens the solenoid valve in the spray port 127, and the cleaning liquid is sprayed into the sleeve 122 and the cylinder 12 through the spray port 127. After that, the staff presses the start button on the control panel 1, and the drive motor 2 drives the plurality of crushing pieces 22 to rotate through the transmission shaft 21. The plurality of crushing pieces 22 drive the cleaning liquid to rotate, and the cleaning liquid impacts the inner wall of the sleeve 122 and the cylinder 12.
