DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0030] It also includes a lower hopper 4, a grinding bin 5, an inclined plate 6, a rotating motor 7, a grinding roller 8 and a collecting box 9; the outer shell 1 is fixedly connected to the lower hopper 4, and the lower hopper 4 is located below the crushing roller 3; the outer shell 1 is bolted to the grinding bin 5, and the grinding bin 5 is located below the lower hopper 4; the grinding bin 5 is provided with two inclined plates 6; the outer shell 1 is fixedly connected to the rotating motor 7; the outer shell 1 is rotatably connected to the grinding roller 8, and the grinding roller 8 is fixedly connected to the output shaft of the rotating motor 7, and the grinding roller 8 is located in the grinding bin 5, and the surface of the grinding roller 8 is provided with grinding teeth for grinding materials; a collecting box 9 is provided at the bottom of the outer shell 1.

[0031] The grinding chamber 5 and the grinding roller 8 are both configured to have a small diameter in the middle and a large diameter at both ends, and the bottom of the grinding chamber 5 is inclined downward from the middle to both ends, and the inclination angle of the bottom of the grinding chamber 5 is less than thirty degrees. When grinding medicinal materials, the ground medicinal material powder can be discharged to the left and right along the inclined bottom of the grinding chamber 5, so that the medicinal material powder can be automatically discharged during the grinding process.

[0032] A cover plate 111 is also included; a cover plate 111 is fixedly connected to the left and right sides of the grinding chamber 5, and the cover plate 111 is inclined toward the middle of the grinding chamber 5.

[0033] It also includes a ventilation pipe 112, an arc pipe 113 and a blowing pipe 114; the grinding chamber 5 is fixedly connected with the ventilation pipe 112, and the ventilation pipe 112 is connected to the external pump; three arc pipes 113 are arranged at the bottom of the cover plate 111, and the arc pipes 113 are all connected to the ventilation pipe 112; each arc pipe 113 is connected to a plurality of blowing pipes 114.

[0034] The scraper 115 is also included; the cover plate 111 is fixedly connected with the scraper 115, and the scraper 115 is in contact with the grinding roller 8, and the contact portion of the scraper 115 and the grinding roller 8 is set to a deformable silicone rubber material, which can fit the grinding teeth on the surface of the grinding roller 8.

[0035] The air blowing pipes 114 are arranged to be inclined from both ends of the grinding roller 8 toward the middle, and all the air blowing pipes 114 are located above the rear side of the grinding roller 8 .

[0036] The rotating assembly includes a rotating motor 101, a gear 102 and a gear 2 103; the housing 1 is fixedly connected to the rotating motor 101; the output shaft of the rotating motor 101 is fixedly connected to the gear 1 102; each crushing roller 3 is fixedly connected to a gear 2 103, and all gears 2 103 are meshed with each other, and gear 2 103 is meshed with gear 1 102.

[0037] The working steps of the above embodiment are as follows: during the specific operation, the rotating motor 101 is first controlled to drive the gear 102 to rotate, and the gear 102 drives the gear 2 103 and the crushing roller 3 to rotate, and then the medicinal materials to be crushed are manually put into the feed nozzle 2, and the medicinal materials enter the shell 1 through the feed nozzle 2, and then fall on the crushing roller 3, and the medicinal materials are preliminarily crushed by the crushing roller 3 to break the medicinal materials into small pieces, and the small pieces of medicinal materials fall downward through the crushing roller 3, and then guided by the lower hopper 4, so that the broken medicinal materials fall into the grinding chamber 5 and the surface of the grinding roller 8, and then the rotating motor 7 is controlled to drive the grinding roller 8 to rotate clockwise from left to right, and as the grinding roller 8 rotates, the small pieces of medicinal materials on the surface of the grinding roller 8 fall between the grinding chamber 5 and the grinding roller 8, and the small pieces of medicinal materials are ground by the continuous rotation of the grinding roller 8 to grind them into medicinal powder;

[0038] However, during the grinding process, the ground medicinal material powder cannot be discharged in time, resulting in continuous accumulation in the grinding equipment, thereby reducing the overall grinding efficiency; therefore, by setting the grinding chamber 5 and the grinding roller 8 to have a small diameter in the middle and a large diameter at both ends, when the grinding roller 8 rotates to grind the medicinal material, the ground medicinal material powder can be discharged along the inclined bottom of the grinding chamber 5 to the left and right sides of the grinding chamber 5 respectively, and finally fall into the collection box 9 below for collection, so that during the grinding process, the ground medicinal material powder can be automatically discharged from the grinding chamber 5 , which not only makes it easy to discharge the medicinal material powder, but also realizes its automatic discharge, so that in the process of grinding, the ground medicinal material powder can be discharged in time, which greatly improves the grinding efficiency of the medicinal material; it should be noted that the bottom inclination angle of the grinding chamber 5 is less than 30 degrees, and during grinding, small pieces of medicinal materials are stuck between the grinding roller 8 and the grinding chamber 5. Only when the small pieces of medicinal materials are ground into powder or smaller pieces of medicinal materials, can the medicinal materials be discharged outward through the grinding roller 8 and the grinding chamber 5, ensuring that in the process of grinding, the medicinal materials can be fully ground by the grinding chamber 5 and the grinding roller 8;

[0039] And through the cooperation of the grinding roller 8 and the grinding chamber 5, the medicinal materials are ground and automatically discharged, so that the grinding roller 8 and the grinding chamber 5 can continuously grind the medicinal materials, which is different from the existing ones and solves the problem that the medicinal materials can only be ground quantitatively;

[0040] When the rotating motor 7 drives the grinding roller 8 to rotate, and in the process of grinding the small pieces of medicinal materials that fall on the surface of the grinding chamber 5 and the grinding roller 8, some of the small pieces of medicinal materials located on the left and right sides of the surface of the grinding roller 8 are ground, and these small pieces of medicinal materials will directly fall on the left and right sides of the grinding chamber 5 for grinding, and their grinding positions are near the edges of the left and right sides of the grinding chamber 5, and the medicinal materials will move to the left and right sides of the grinding chamber 5 during the grinding process, so that the small pieces of medicinal materials located on the left and right sides of the grinding roller 8 have a short grinding time when they are ground, and there is a situation where they are discharged from the grinding chamber 5 before they are fully ground. When grinding the surface of the grinding roller 8, the left and right sides of the grinding roller 8 are covered by a cover plate 111 which is inclined toward the middle of the grinding chamber 5 to prevent the medicinal materials from falling directly from the left and right sides of the grinding roller 8 into the grinding chamber 5 for grinding, and the medicinal materials falling on the left and right sides of the grinding roller 8 are guided to the middle, so that the small pieces of medicinal materials falling on the grinding chamber 5 and the surface of the grinding roller 8 can only be ground from the middle of the grinding roller 8, so that the medicinal materials move from the middle of the grinding roller 8 to the left or right end when being ground, so that the moving distance of the medicinal materials between the grinding chamber 5 and the grinding roller 8 is increased, thereby increasing the grinding time of the medicinal materials and ensuring that the medicinal materials can be fully ground;

[0041] Furthermore, during grinding, the external pump is controlled to pass gas into the ventilation pipe 112, and the gas is blown out from the air blowing pipe 114 through the arc tube 113, and the air blowing pipe 114 is inclined from both ends of the grinding roller 8 to the middle, and all the air blowing pipes 114 are located above the rear side of the grinding roller 8. The air blowing pipe 114 blows downward from the rear side of the grinding roller 8, and the blown gas can flow downward along the surface of the grinding roller 8, blow the medicinal materials being ground, and move the medicinal materials accumulated at the rear side of the grinding roller 8 to the bottom of the grinding chamber 5. Blowing can prevent the medicinal materials from moving together when the grinding roller 8 rotates clockwise from left to right, so that a large amount of medicinal materials are accumulated at the rear side of the grinding roller 8, reducing the grinding efficiency of the medicinal materials. The blowing pipe 114 is inclined from both ends to the middle, and can also apply a force to the medicinal materials to move toward the middle, slowing down the discharge of the medicinal materials outward, and improving the grinding effect of the medicinal materials between the grinding chamber 5 and the grinding roller 8. It is explained here that when the external pump machine passes the gas into the ventilation pipe 112, the flow rate of the gas passed by the external pump machine is slow, so as to avoid the problem of dust from the medicinal material powder;

[0042] At the same time, during the grinding process of the grinding roller 8, the scraper 115 is in contact with the grinding roller 8, so that the surface of the grinding roller 8 can be scraped off, and the medicinal powder attached to the surface can be scraped off, thereby preventing the ground medicinal powder from adhering to the surface of the grinding roller 8 during the rotation and grinding of the grinding roller 8.

[0043] On the basis of Example 1, Figure 4-5 and Figure 7 As shown, a screen 201 is also included; a screen 201 is fixedly connected to the left and right sides of the grinding chamber 5, and the screen 201 is fixedly connected to the inner wall of the shell 1.

[0044] It also includes a paddle plate 202 and a guide plate 203; a paddle plate 202 is fixedly connected to the left and right sides of the grinding roller 8, and the paddle plate 202 is in contact with the screen 201; each paddle plate 202 is fixedly connected to a guide plate 203, and the guide plate 203 is inclined toward the grinding roller 8, and the guide plate 203 does not contact the screen 201.

[0045] On the basis of the above-mentioned embodiment, when the medicinal material is ground between the grinding chamber 5 and the grinding roller 8, it is still impossible to ensure that the medicinal material can be fully ground. There are always some larger medicinal material particles that have not been fully ground and are discharged from the left or right side of the grinding chamber 5, so that the coarseness of the ground and collected medicinal material powder is different; therefore, when the ground medicinal material powder is discharged from the left or right side of the grinding chamber 5, the medicinal material powder will first fall on the screen 201, and the discharged medicinal material powder will be screened by the screen 201 to screen out the larger medicinal material particles that have not been fully ground, and the medicinal material powder that meets the requirements will pass through the screen 201 and fall and be collected in the collection box 9 below; and as the rotating motor 7 drives the grinding roller 8 to rotate clockwise from left to right, The grinding roller 8 drives the paddle 202 to rotate, and the paddle 202 rotates on the surface of the screen 201 to paddle the medicinal material powder falling on its surface, thereby accelerating the screening of the medicinal material powder and preventing the medicinal material powder from accumulating on the surface of the screen 201 and clogging it. At the same time, through the movement of the paddle 202, the larger medicinal material particles screened out from the surface of the screen 201 can be scraped away, and the larger medicinal material particles are scraped and gathered between the paddle 202 and the guide plate 203. When the paddle 202 rotates to the upper part, the gathered larger medicinal material particles slide back onto the cover plate 111 under the guidance of the guide plate 203, and finally fall back onto the grinding roller 8, and are subsequently re-ground by the grinding roller 8. In this way, it is ensured that all medicinal materials can be fully ground.

[0046] On the basis of Example 2, Figure 2 and Figure 8-9 As shown, it also includes a driving motor 301, a rotating rod 302, a scraper 303 and an air jet 304; the outer shell 1 is fixedly connected to two driving motors 301; the outer shell 1 is rotatably connected to two rotating rods 302, and the rotating rods 302 are fixedly connected to the output shaft of the driving motor 301, and the rotating rods 302 are located above the crushing roller 3; each rotating rod 302 is fixedly connected to a plurality of scrapers 303; each rotating rod 302 is provided with a plurality of air jets 304, and the rotating rod 302 is configured to be hollow and connected to an external gas supply structure.

[0047] It also includes a transmission roller 311, an electric push rod 312 and a cutter 313; the feed pipe mouth 2 is rotatably connected to three transmission rollers 311, and all the transmission rollers 311 are distributed in a stepped manner, and the transmission rollers 311 are configured as electric drive rollers; the feed pipe mouth 2 is fixedly connected to two electric push rods 312; all the telescopic parts of the electric push rods 312 are commonly fixedly connected to a cutter 313, and the cutter 313 is slidably connected to the feed pipe mouth 2.

[0048] On the basis of the above-mentioned embodiment, when it is necessary to crush rattan-like and long-strip medicinal materials, the rattan-like medicinal materials are usually manually held and slowly placed into the feeding nozzle 2. During this operation, it is necessary to pay attention to the feeding of rattan-like medicinal materials at all times, which not only increases the labor cost, but also makes it easy for workers to inhale medicinal material dust when they are close to the equipment, which has an impact on their health. In addition, rattan-like medicinal materials contain more fibers, which are relatively tough. When the crushing roller 3 is rotated and crushed, the fibers are easily entangled on the surface of the crushing roller 3, making it impossible to fully crush them. Therefore, when people When the worker puts the rattan-shaped medicinal material into the feed pipe opening 2, the transmission roller 311 is controlled to rotate to transport the medicinal material downward, and a plurality of transmission rollers 311 distributed in a stepped manner rotate relative to each other to realize automatic downward transportation of the medicinal material. In addition, during transportation, the electric push rod 312 is controlled to drive the cutter 313 to move back and forth in the feed pipe opening 2 to cut the rattan-shaped and long-strip medicinal material transported downward into small segments, so as to avoid the rattan-shaped medicinal material from being entangled when being crushed by the crushing roller 3, so that it cannot be fully crushed;

[0049] Moreover, when the crushing roller 3 rotates to crush the medicinal materials, some of the crushed medicinal materials will adhere to the surface of the crushing roller 3, making it impossible for the medicinal materials to fall to the bottom in time for the grinding process, and too much medicinal materials adhering to the surface of the crushing roller 3 will reduce its crushing effect on the medicinal materials. Therefore, when the crushing roller 3 rotates, the driving motor 301 is controlled to drive the rotating rod 302 and other connected parts to rotate clockwise from left to right, and the rotating rod 302 drives the scraper 303 to rotate, so as to scrape and clean the surface of the crushing roller 3, and scrape off the medicinal materials adhering to the surface, so as to prevent some of the medicinal materials from adhering to the surface of the crushing roller 3 and affecting its normal crushing effect; at the same time, during the rotation of the rotating rod 302, the external gas supply mechanism is controlled to ventilate the rotating rod 302, so that the gas is ejected outward from the nozzle 304 to blow the cleaned scraper 303, so as to prevent medicinal materials from remaining on the scraper 303 when the scraper 303 is working, thereby ensuring that the scraper 303 can be used normally.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
