DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below.

[0021] During long-term use, Chinese medicine powder is easily accumulated between the existing crushing roller and the gear ring, resulting in blockage between the two, which will cause a large amount of Chinese medicine powder to accumulate in the crushing chamber, reducing the available space in the crushing chamber, thereby affecting the crushing efficiency and quality of Chinese medicinal materials. For this reason, operators need to frequently disassemble the grinder and clean the inside. However, frequent disassembly and maintenance not only increases the workload, but may also cause the seal of the grinder to fail, thereby causing dust leakage during the Chinese medicine crushing process, resulting in waste of Chinese medicine powder.

[0022] Reference Figure 1-Figure 8The following is an embodiment of the present invention, a Chinese herbal medicine ultrafine grinder, including a frame 1, wherein the internal structure of the frame 1 is not shown in the figure, a pulley is installed at the bottom of the frame 1 to facilitate changing the placement of the device, and a control panel not shown in the figure is arranged on the outside of the frame 1, and a cyclone separator 101 and a pulse dust collector 102 are installed on the frame 1, and the cyclone separator 101 and the pulse dust collector 102 are both electrically connected to the control panel, and the lower side of the cyclone separator 101 is connected to a collecting container, wherein the cyclone separator 101 is connected to the pulse dust collector 102, and the cyclone separator 101 collects the crushed Chinese medicine into the inside thereof through negative pressure, and then uses centrifugal force The heavier particles (i.e., Chinese medicine particles that do not meet the standards) and the lighter particles (i.e., Chinese medicine particles that meet the standards) are collected separately. The Chinese medicine particles that do not meet the standards move toward the cylinder wall under the action of centrifugal force. The Chinese medicine particles that do not meet the standards can be collected separately or transported to the position of secondary crushing through pipelines. The Chinese medicine particles that meet the standards are discharged from the bottom of the cyclone separator 101 and enter the collection container. The pulse dust collector 102 is provided with a filter bag. The dust-containing gas passes through the filter bag, and the dust is trapped on the surface of the filter bag; the feeder 2 is arranged on the frame 1. The feeder 2 has a feed hopper 201 and a conveying pipe 202. The conveying pipe 202 can be provided with a spiral conveying structure (i.e., an auger) or a vibrating conveying structure. In order to transport the Chinese medicine in the feed hopper 201 to the right side of the feed pipeline 202 and maintain the stability of the flow of Chinese medicine to reduce the phenomenon of material blockage in the feed pipeline 202, the feed hopper 201 is connected to the feed pipeline 202; the pulverizer 3 is located on one side of the feed pipeline 202, and the feed pipeline 202 and the cyclone separator 101 are both connected to the pulverizer 3; the trigger component 4 is located in the feed pipeline 202, and is used to detect the accumulation of materials in the feed pipeline 202; the electric control telescopic rod 501, the electric control telescopic rod 501 is at least two, the electric control telescopic rod 501 is electrically connected to the control panel, and all the electric control telescopic rods 501 are circumferentially arranged on the pulverizer 3 to dredge the gear ring 502, the unblocking gear ring 502 is sealingly and slidably connected in the frame 1, the telescopic end of the electric-controlled telescopic rod 501 is fixedly connected to the unblocking gear ring 502, after blockage occurs in the pulverizer 3, the trigger component 4 is triggered and the signal is fed back to the control panel, the control panel controls the telescopic end of the electric-controlled telescopic rod 501 to contract, the telescopic end of the electric-controlled telescopic rod 501 drives the unblocking gear ring 502 to move upward, pushes out the Chinese medicine particles blocked in the pulverizer 3, and dredges the pulverizer 3, ensuring its normal operation without disassembling the pulverizer 3, thereby avoiding frequent disassembly and maintenance of the pulverizer 3 after blockage, resulting in failure of its sealing, and then causing dust leakage during the Chinese medicine pulverization process, resulting in waste of Chinese medicine powder.

[0023] Furthermore, the pulverizer 3 includes: a pulverizing shell 301, which is mounted on the frame 1 by bolts, and an electrically controlled telescopic rod 501 is fixedly connected to the pulverizing shell 301; a plurality of crushing teeth 302, which are circumferentially arranged on the inner wall of the pulverizing shell 301, and the plurality of crushing teeth 302 are increased in size from close to the feeding pipe 202 to far away; a pulverizing roller 303, which is rotatably arranged in the pulverizing shell 301, and the dredging gear ring 502 is sealed and slidably matched with the plurality of crushing teeth 302 and the pulverizing roller 303, and the pulverizing roller 303 is provided with grinding teeth evenly distributed in the circumferential direction. In this embodiment, the lower part of the grinding teeth distributed circumferentially on the pulverizing roller 303 is a pointed end, so that the dredging gear ring 502 can be inserted from bottom to top into the plurality of crushing teeth. Between the crushing teeth 302 and the crushing roller 303, the lower side of the crushing roller 303 can be directly connected to the output shaft of the motor, or driven to rotate by an external pulley. No matter which transmission structure is used, it can be embedded in the frame 1 and electrically connected to the control panel to drive the crushing roller 303 to rotate at a high speed to crush the Chinese medicine. The distribution form of the size of the crushing teeth 302 mentioned above makes the gap between the several crushing teeth 302 and the crushing roller 303 gradually decrease from left to right. The Chinese medicine enters the gap between the left crushing teeth 302 and the crushing roller 303 from the left feeding pipeline 202. With the rotation of the crushing roller 303, the Chinese medicine gradually rotates to the gap between the right crushing teeth 302 and the crushing roller 303, and the Chinese medicine is crushed layer by layer (the above left and right directions are both in Figure 4 As an example); there are several hammer knives 304, and the several hammer knives 304 are evenly arranged on the pulverizing roller 303 in the circumferential direction. The pulverizing roller 303 rotates at a high speed and drives all the hammer knives 304 to rotate, and hits the Chinese medicine, so that when the Chinese medicine enters the gap between the crushing teeth 302 and the pulverizing roller 303, it is initially crushed by the hammer knives 304 to prevent the Chinese medicine raw materials from being too large to enter the gap between the crushing teeth 302 and the pulverizing roller 303. In addition, during the rotation of the pulverizing roller 303, it uses the centrifugal force to throw the larger Chinese medicine particles to the circumferentially distributed hammer knives 304, so that the Chinese medicine The medicine particles continuously impact the crushing teeth 302 and the hammer knife 304 to enhance the degree of crushing of the Chinese medicine. The height of the crushing teeth 302 is X, the height of the crushing roller 303 is Y, and the height of the hammer knife 304 is L, X>Y+L, which is used to increase the roughness of the inner wall of the crushing shell 301. Even if the Chinese medicine is splashed after contacting the hammer knife 304, it will splash upward onto the crushing teeth 302 (in this embodiment, the uppermost side of the crushing teeth 302 can be in contact with the upper side wall of the crushing shell 301), increasing the number of collisions between the Chinese medicine and the crushing teeth 302, thereby enhancing the crushing effect of the Chinese medicine.

[0024] Furthermore, the trigger assembly 4 includes: a sealing ring 401, which is sealingly slidably arranged in the feed pipe 202, and the sealing ring 401 is located on the left side of the connection between the feed hopper 201 and the feed pipe 202 to prevent the Chinese medicine from entering the left side of the sealing ring 401, and an elastic member is fixedly connected between the sealing ring 401 and the feed pipe 202, wherein the elastic member is a compression spring; a pressure sensor 402, which is arranged on the left side of the inner wall of the feed pipe 202, and the pressure sensor 402 is electrically connected to the control panel, and the pressure sensor 402 and the sealing ring 401 are connected. The gap between the crushing teeth 302 and the crushing roller 303 is blocked by the accumulated Chinese medicine particles, and the Chinese medicine in the crushing shell 301 can no longer enter the gap between the crushing teeth 302 and the crushing roller 303. The Chinese medicine is accumulated in the circumferential position of the crushing roller 303 under the action of the centrifugal force of the crushing roller 303, resulting in an increase in the amount of Chinese medicine in the crushing shell 301, and an increase in the amount of Chinese medicine accumulated on the upper side of the crushing roller 303, so that a large amount of Chinese medicine is gradually accumulated at the connecting port of the feeding pipeline 202. The resistance of the Chinese medicine to the connecting port of the feeding pipeline 202 increases, so that the speed of the Chinese medicine in the feeding pipeline 202 is slowed down, the sealing ring 401 is squeezed by the Chinese medicine, the elastic part of the sealing ring 401 is compressed, and the gas in the sealing chamber forms a high pressure, which increases the pressure on the pressure sensor 402. The pressure sensor 402 feeds back the command to the control panel, and the control panel controls the transmission structure of the crushing roller 303 and the conveying structure in the feeding pipeline 202 to stop running. After the conveying structure in the channel 202 stops running, the control panel controls the telescopic ends of the two electrically controlled telescopic rods 501 to shrink at the same time, and the two electrically controlled telescopic rods 501 drive the dredging gear ring 502 to move upward, and the dredging gear ring 502 passes through the gaps between the plurality of crushing teeth 302 and the crushing roller 303, and pushes the Chinese medicine particles accumulated in the gaps to the top of the crushing roller 303, and then the pushed Chinese medicine particles are drawn out by the cyclone separator 101 to the inside thereof, so as to prevent the crushing shell 301 from being blocked, thereby improving the crushing efficiency and crushing quality of the Chinese medicine; Working principle: First, the cyclone separator 101, the pulse dust collector 102, the transmission structure of the crushing roller 303 and the conveying structure in the feeding pipe 202 are turned on through the control panel, and then the Chinese medicine is conveyed to the crushing shell 301 through the feed hopper 201 and the feeding pipe 202. The crushing roller 303 rotates and cooperates with all the crushing teeth 302 to crush the Chinese medicine in the gaps between them. At the same time, the hammer knife 304 rotates and hits the Chinese medicine to perform the initial crushing of the Chinese medicine. The Chinese medicine particles are accumulated in the gap between the crushing teeth 302 and the crushing roller 303, resulting in blockage in the crushing shell 301. The sealing ring 401 slides and the pressure sensor 402 is triggered by pressure. The control panel closes the transmission structure of the crushing roller 303 and the conveying structure in the feeding pipe 202. The control panel turns on two electrically controlled telescopic rods 501, and the electrically controlled telescopic rods 501 drive the dredging gear ring 502 to move upward (in this embodiment, the crushing roller 3 03, the lower part of the grinding teeth distributed circumferentially is a tip, and the dredging gear ring 502 is inserted between the crushing teeth 302 and the crushing roller 303 through its lower tip). The dredging gear ring 502 pushes out the Chinese medicine particles accumulated in the gap between the crushing teeth 302 and the crushing roller 303, and the cyclone separator 101 extracts the pushed out Chinese medicine particles to prevent the gap between the crushing teeth 302 and the crushing roller 303 from being blocked, which will affect the crushing efficiency and crushing quality of the Chinese medicine. After the dredging is completed, the control panel controls the two electric telescopic rods 501 to reset, and the telescopic end of the electric telescopic rod 501 drives the dredging gear ring 502 to move and reset, and the control panel controls the electric telescopic rod 501 to close. After stopping using the device, the operator closes the cyclone separator 101, the pulse dust collector 102, the transmission structure of the crushing roller 303 and the conveying structure in the feed pipe 202 through the control panel, and finally cleans the device for the next use.

[0025] In the above-mentioned embodiment, the lower part of the grinding teeth distributed circumferentially on the pulverizing roller 303 is a pointed end, while in the following embodiment, the lower side of the grinding teeth is a flat surface.

[0026] The above content is Example 1. On the basis of the above, the following is Example 2, which further includes: a flexible gear ring 6, which is arranged at the lower part of the crushing roller 303, and is used to guide the dredging gear ring 502 between the plurality of crushing teeth 302 and the crushing roller 303. Before the dredging gear ring 502 enters the gap between the crushing teeth 302 and the crushing roller 303, the dredging gear ring 502 first passes through the flexible gear ring 6. If the flexible gear ring 6 cannot be completely fitted with the dredging gear ring 502 due to rotation, the dredging gear ring 502 squeezes the flexible gear ring 6 to rotate, so that the flexible gear ring 6 drives the crushing roller 303 to rotate, so that the dredging gear ring 502 fits with the crushing roller 303; In the above solution, a flexible gear ring 6 is added to facilitate the insertion of the dredging gear ring 502 into the gap between the crushing teeth 302 and the pulverizing roller 303 , thereby reducing the friction between the dredging gear ring 502 and all the crushing teeth 302 and the pulverizing roller 303 .

[0027] Further, the crushing roller 303 is provided with an annular cavity. A moving ring 701 is arranged in the annular cavity of the crushing roller 303. The moving ring 701 is provided with a plurality of bumps. The vertical height H that the bumps on the moving ring 701 can move is such that H > L and X < Y + H, which is used to enable the hammer knife 304 to move to the upper surface of the dredging gear ring 502. In this embodiment, there is a gap between the upper side of the crushing tooth 302 and the upper side of the inner wall of the crushing housing 301, but still X > Y + L. After the dredging gear ring 502 moves to contact all the hammer knives 304, the dredging gear ring 502 can drive all the hammer knives 304 to move upward to the upper side of the crushing tooth 302. The hammer knife 304 is fixedly connected to the moving ring 701 through a connecting rod. The hammer knife 304 is in extrusion fit with the dredging gear ring 502. A plurality of arc-shaped grooves are arranged in the crushing roller 303. The bumps of the moving ring 701 slide in adjacent arc-shaped grooves. After the dredging gear ring 502 extrudes all the hammer knives 304 to move upward, the hammer knife 304 drives the moving ring 701 to move upward through the connecting rod. The bumps of the moving ring 701 move along the adjacent arc-shaped grooves, causing the moving ring 701 to rotate. The moving ring 701 drives the adjacent hammer knives 304 to rotate through the connecting rod, so that the hammer knife 304 rotates during the upward movement. A rotating ring 702 that is sealingly matched with the annular cavity is arranged on the crushing roller 303 to prevent Chinese medicine particles from entering the annular cavity. The connecting rod of the hammer knife 304 is slidably connected to the rotating ring 702. A plurality of elastic members are fixedly connected between the moving ring 701 and the rotating ring 702. The number of elastic members is the same as the number of hammer knives 304. Among them, the elastic member is a compression spring. When the moving ring 701 moves upward, this elastic member is compressed. The rotation direction of the crushing roller 303 is from the lower end direction to the upper end direction of the arc-shaped groove of the crushing roller 303, which is used to prevent relative movement between the crushing roller 303 and the moving ring 701 during rotation. A plurality of scraping blocks 801 are arranged on the hammer knife 304. A flexible part is arranged on the lower side of the scraping block 801. The number of scraping blocks 801 is the same as the number of hammer knives 304. The hammer knife 304 rotates during the upward movement. The hammer knife 304 drives the adjacent scraping blocks 801 to rotate. The scraping blocks 801 scrape the Chinese medicine particles attached to the upper side surface of the dredging gear ring 502, thereby preventing the Chinese medicine particles from being compacted by the upper-side Chinese medicine on the dredging gear ring 502. After the dredging gear ring 502 moves downward and resets, the Chinese medicine particles still adhere to the dredging gear ring 502, resulting in a large number of Chinese medicine particles still remaining between the crushing tooth 302 and the crushing roller 303 after cleaning, and further affecting the cleaning effect of the dredging gear ring 502 on the crushing tooth 302 and the crushing roller 303. An elastic member is fixedly connected between the scraping block 801 and the adjacent hammer knife 304. Among them, the elastic member is a蓄力 elastic telescopic rod. The scraping block 801 is initially limited by the adjacent crushing tooth 302, so that the elastic member of the scraping block 801 is in a compressed and蓄力 state. After all the hammer knives 304 move upward to the upper side of the crushing tooth 302, this elastic member pops out and drives the adjacent scraping blocks 801 to move, so that all the scraping blocks 801 are circumferentially dispersed. It should be noted that the term "蓄力" in the original text may not be a standard English word. If there is a more accurate or common English expression for it, it can be adjusted accordingly. Also, some parts of the text seem a bit complex and might need further clarification in the context of the overall patent understanding, but this translation adheres to the requirements as closely as possible.The contact area between the scraper block 801 and the upper side of the dredging gear ring 502 is increased, thereby enhancing the cleaning effect of the scraper block 801 on the dredging gear ring 502 and reducing the amount of Chinese medicine particles attached to the dredging gear ring 502. After cleaning, the dredging gear ring 502 is reset, the elastic part of the moving ring 701 rebounds and drives it to reset, the flexible part on the lower side of the scraper block 801 squeezes the adjacent crushing teeth 302, the scraper block 801 resets and drives its elastic part to reset, the height of the scraper block 801 is less than the height of the adjacent hammer blade 304, and the lower side height of the inner wall of the feeding pipeline 202 is flush with the upper side height of the scraper block 801 to ensure that the material contacts the hammer blade 304 after entering the crushing shell 301.

[0028] Working principle: After the dredging gear ring 502 pushes out the Chinese medicine particles accumulated in the gap between the crushing teeth 302 and the crushing roller 303, the hammer knife 304 drives the moving ring 701 to move through the connecting rod, and the elastic part of the moving ring 701 is compressed. The moving ring 701 cooperates with the protrusion and the arc groove to make the hammer knife 304 rotate during the upward movement. The hammer knife 304 drives the adjacent scraper block 801 to rotate, and scrapes off the Chinese medicine particles attached to the upper side of the dredging gear ring 502 to prevent the Chinese medicine particles from adhering to the dredging gear ring 502 and reset it, resulting in a large number of Chinese medicine particles still existing between the crushing teeth 302 and the crushing roller 303 after cleaning, thereby affecting the cleaning effect of the dredging gear ring 502 on the crushing teeth 302 and the crushing roller 303.

[0029] In summary, the invention includes but is not limited to the above embodiments. Any equivalent substitution or partial improvement made under the spirit and principle of the invention shall be deemed to be within the protection scope of the invention.
