[0002] In the process of preparing Chinese herbal medicines, there are many steps that require attention, especially the powder grinding process in the process of preparing Chinese herbal medicines. When grinding Chinese herbal raw materials, the raw materials need to be ground into powder. In the process of grinding into powder, a large amount of floating tiny particles, namely drug dust, will be generated. These dusts will be blown up and scattered in the working environment in large quantities under the influence of tiny airflows. If the working environment is covered with a large amount of dust, it is very easy to cause dust explosion. Not only will a large amount of floating dust be generated in the process of grinding the raw materials, but when the grinder is opened, a large amount of dust will be blown up by the grinder. When pouring out the powder in the grinder, flying powder will still be generated. In addition, the powder that needs to be ground multiple times to increase the degree of refinement will still generate flying powder when feeding. Therefore, in the process of grinding Chinese herbal raw materials into powder, many steps will generate a large amount of flying dust.

[0003] Therefore, it is necessary to develop a Chinese herbal medicine grinding device that prevents medicine powder from flying to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0035] like Figure 1-Figure 6 As shown, a Chinese medicine decoction piece grinding device for preventing medicine powder from flying comprises a mounting frame 1, a fixing frame 2, a connecting shaft 3, a grinding mechanism 4, a cover mechanism 5, a sealing mechanism 6 and a suction mechanism 7. The mounting frame 1 is a wall-mounted mounting structure. The front side of the mounting frame 1 is fixedly connected to the fixing frame 2. The fixing frame 2 is a U-shaped structure. The U-shaped structure of the fixing frame 2 is rotatably connected to the connecting shaft 3 at both walls. A grinding mechanism 4 is arranged between the connecting shafts 3. The grinding mechanism 4 is used to grind the raw materials of Chinese medicine decoction pieces. A cover mechanism 5 is arranged on the grinding mechanism 4. The cover mechanism 5 is used to be set and docked on the grinding mechanism Above the mechanism 4, a closing mechanism 6 is provided inside the cover mechanism 5, and the closing mechanism 6 is used to controllably close the communication between the cover mechanism 5 and the outside world. The closing mechanism 6 is used to close the communication between the grinding mechanism 4 and the cover mechanism 5, so that the inside of the grinding mechanism 4 is in an independent closed space. The cover mechanism 5 and the closing mechanism 6 can prevent the flying of medicinal powder when the grinding mechanism 4 grinds the medicinal raw materials. A suction mechanism 7 is provided on the rear side of the cover mechanism 5, and the suction mechanism 7 is used to absorb the flying medicinal powder between the cover mechanism 5 and the grinding mechanism 4 to prevent the medicinal powder from being directly discharged to the outside world and causing air pollution.

[0036] When processing Chinese herbal medicine raw materials, there is a process that requires grinding the Chinese herbal medicine raw materials into powder. In order to prevent the flying powder from being generated in the process of grinding into powder and scattering in the external environment, and to prevent the powder from being scattered and not deposited after the powder is ground into powder and scattering out of the external environment, the Chinese herbal medicine grinding device for preventing the flying powder can be used; the Chinese herbal medicine grinding device for preventing the flying powder can be installed in the Chinese herbal medicine production area through the mounting frame 1, and then the power supply and control line pipe are connected, and then the exhaust gas pipeline is connected to the suction mechanism 7; then the Chinese herbal medicine grinding device for preventing the flying powder can be used to grind the Chinese herbal medicine raw materials Grinding, the cover mechanism 5 can be withdrawn from the top of the grinding mechanism 4, and then the Chinese medicine raw materials to be ground are placed inside the grinding mechanism 4, and then the cover mechanism 5 is re-installed and docked on the upper side of the grinding mechanism 4, so that the cover mechanism 5 covers the upper opening of the grinding mechanism 4, and then the closing mechanism 6 is controlled to close the communication between the cover mechanism 5 and the outside, and the closing mechanism 6 closes the communication between the grinding mechanism 4 and the cover mechanism 5, so that the inside of the grinding mechanism 4 is in an independent closed space, and then the grinding mechanism 4 can be started to grind the Chinese medicine raw materials inside it. In the process of grinding the raw materials by the grinding mechanism 4, the connecting shaft 3 can be used to reciprocate and rotate the grinding mechanism 4 at a small angle, so that the powder inside the grinding mechanism 4 can fully participate in the grinding, thereby improving the uniformity of grinding; as mentioned above, in the process of grinding the Chinese medicine raw materials by the grinding mechanism 4, the generated powder will be blocked by the closing mechanism 6 and will not fly to the cover mechanism 5 and the outside space, which can effectively protect the air environment of the outside space; after the grinding of the Chinese medicine raw materials is completed, the closing mechanism 6 can be controlled to operate first, so that the closing mechanism 6 reopens the communication between the cover mechanism 5 and the grinding mechanism 4 At this time, the flying powder will be in the closed space between the grinding mechanism 4 and the cover mechanism 5. At this time, the suction mechanism 7 can be started to make the suction mechanism 7 suck out the flying powder in the closed space between the grinding mechanism 4 and the cover mechanism 5, thereby removing the flying powder in the closed space between the grinding mechanism 4 and the cover mechanism 5. When the cover mechanism 5 is withdrawn later, there will be no flying powder in the space between the grinding mechanism 4 and the cover mechanism 5 to float to the outside space; then the grinding mechanism 4 can be rotated by the connecting shaft 3 to collect the ground powder. Example 2

[0037] like Figure 7As shown, the grinding mechanism 4 includes a mounting ring 41, a grinding cylinder 42, a first docking sleeve 43 and a grinding motor 44. The mounting ring 41 is fixedly connected between the connecting shafts 3 on both sides. The grinding cylinder 42 is fixedly connected between the mounting rings 41. The grinding cylinder 42 is an existing blade powdering mechanism. The first docking sleeve 43 is fixedly connected at the left and right sides of the upper side of the grinding cylinder 42. The first docking sleeve 43 is a nut structure. The grinding motor 44 is fixedly connected to the lower side of the grinding cylinder 42. The output shaft of the grinding motor 44 extends into the lower side wall of the grinding cylinder 42 and is connected to its blade structure.

[0038] The grinding motor 44 is started, and the grinding motor 44 drives the blade structure of the grinding cylinder 42 to rotate, thereby breaking and grinding the Chinese medicine raw materials inside the grinding cylinder 42.

[0039] like Figure 8-Figure 11 As shown, the cover mechanism 5 includes a sealing sleeve 51, a relay cabin 52 and a first docking locking member 53. The sealing sleeve 51 is sleeved on the upper side of the grinding cylinder 42. The sealing sleeve 51 is a structure with a seal at the bottom. The sealing structure of the sealing sleeve 51 contacts the upper edge of the grinding cylinder 42 for sealing. The sealing sleeve 51 is an annular structure. The upper side of the sealing sleeve 51 is fixedly connected with the relay cabin 52. The relay cabin 52 is a circular through-hole liner structure. The closing mechanism 6 is located in the circular through-hole liner structure of the relay cabin 52. The suction mechanism 7 is located at the rear side of the relay cabin 52 and is interconnected with its circular through-hole liner structure. The left and right sides of the sealing sleeve 51 are fixedly connected with the first docking locking member 53. The first docking locking member 53 is a fastening bolt. The first docking locking member 53 cooperates with the first docking sleeve 43.

[0040] After placing the Chinese medicine raw materials to be ground in the grinding cylinder 42, the sealing sleeve 51 can be mounted on the upper side of the grinding cylinder 42, so that the sealing structure of the sealing sleeve 51 contacts the upper edge of the grinding cylinder 42 to complete the sealing, and then the first docking locking member 53 is docked with the first docking sleeve 43 corresponding to the position, so that the sealing sleeve 51 and the relay cabin 52 are sealed and assembled on the upper side of the grinding cylinder 42, and then the closing mechanism 6 is controlled to close the upper side of the grinding cylinder 42, so that an independent closed space is formed inside the grinding cylinder 42; after the grinding of the Chinese medicine raw materials is completed, the closing mechanism 6 can be controlled to reopen the space between the grinding cylinder 42 and the relay cabin 52, and then the suction mechanism 7 is started to suck out the flying powder in the space between the grinding cylinder 42 and the relay cabin 52; then the first docking locking member 53 can be released from the first docking sleeve 43, and then the relay cabin 52 and the sealing sleeve 51 can be withdrawn from the upper side of the grinding cylinder 42.

[0041] like Figure 8-Figure 11 As shown, the closing mechanism 6 includes a bracket 61, an electric push rod 62 and a closing cylinder 63. The bracket 61 is arranged on the upper side of the relay cabin 52. The electric push rod 62 is fixedly connected to the middle part of the bracket 61. The electric push rod 62 is vertically installed. The propulsion member of the electric push rod 62 is vertically arranged downward. The lower side of the propulsion member of the electric push rod 62 is fixedly connected to the closing cylinder 63. The structure of the closing cylinder 63 is a structure with a sealing ring layer on the lower side. The closing cylinder 63 is located inside the circular through hole inner liner structure of the relay cabin 52 and maintains a sealed fit through its sealing ring layer structure.

[0042] After the sealing sleeve 51 and the relay chamber 52 are sealed and assembled on the upper side of the grinding cylinder 42, the electric push rod 62 can be controlled to operate, so that the electric push rod 62 drives its propulsion member to move downward, thereby driving the sealing cylinder 63 to move downward, so that the structural sealing cover with a sealing ring layer on the lower side of the sealing cylinder 63 covers the upper side of the grinding cylinder 42, so that an independent closed space is formed inside the grinding cylinder 42 for grinding the raw materials, thereby preventing the raw materials from flying to the outside during the grinding process; after the powder is ground, , the electric push rod 62 can be controlled to drive its propulsion member to move upward, thereby moving the closing cylinder 63 upward, so that the closing cylinder 63 is out of contact with the upper side of the grinding cylinder 42, so that the flying powder in the grinding cylinder 42 is in the internal space of the relay cabin 52, and the closing cylinder 63 will also block the powder from flying out of the environmental space outside the relay cabin 52, and then the suction mechanism 7 can be started to operate, so that the suction mechanism 7 can suck out the flying powder in the relay cabin 52 and the grinding cylinder 42.

[0043] like Figure 8-Figure 11 As shown, the suction mechanism 7 includes a suction pipe 71 and a suction pump 72. The suction pipe 71 is fixedly connected to the middle position of the rear side of the relay cabin 52. The suction pipe 71 is installed on the rear side of the relay cabin 52 in a sealed flange type. The suction pipe 71 is communicated with the internal space of the relay cabin 52. The rear side of the relay cabin 52 is fixedly connected with a suction pump 72. The suction pump 72 is an air pump. The suction end of the suction pump 72 is connected to the suction pipe 71, and the exhaust end of the suction pump 72 can be connected to the external exhaust pipe.

[0044] The external exhaust pipe is connected to the exhaust end of the suction pump 72; after the raw material is ground, and the electric push rod 62 is controlled to drive the closed cylinder 63 to move upward to a position where it will not block the suction pipe 71, the suction pump 72 can be started to work, and the suction pump 72 will draw air from the space inside the relay cabin 52 and the grinding cylinder 42 to form a negative pressure in the space inside the relay cabin 52 and the grinding cylinder 42, so that the flying powder in the space of the relay cabin 52 and the grinding cylinder 42 is brought out to the suction pipe 71 by the negative pressure, and discharged to the external exhaust pipe by the suction pump 72, so that the flying powder will not be directly scattered in the environmental space, but will be discharged from the external exhaust pipe. Example 3

[0045] like Figure 8-Figure 16 As shown, it also includes a drainage mechanism 8, which includes a drainage cabin 81, a sealing ring 82, a second docking sleeve 83 and a loading assembly 9. The drainage mechanism 8 is arranged on the front side of the relay cabin 52, and the drainage mechanism 8 is generally at an angle of 45 degrees to the relay cabin 52. The drainage mechanism 8 is used to feed and discharge the powder that needs to be further ground after preliminary processing without the powder flying, so as to avoid the powder flying when the powder that needs to be further processed is fed and taken for secondary processing. The front side of the relay cabin 52 is opened, and the front side of the relay cabin 52 is sealed and fixedly connected with the drainage cabin 81, and the drainage cabin 81 is a rear square shell frame structure. The front part of the drainage cabin 81 is a round shell and round hole structure. The square shell frame structure of the drainage cabin 81 is interconnected with the opening structure on the front side of the relay cabin 52, so that the internal space of the drainage cabin 81 is interconnected with the internal space of the relay cabin 52. A sealing ring 82 is fixedly connected to the round shell structure of the drainage cabin 81. The outside of the round shell structure of the drainage cabin 81 is symmetrically fixedly connected with a second docking sleeve 83, and the second docking sleeve 83 is a nut. A loading component 9 is provided at the front end of the round shell structure of the drainage cabin 81. The loading component 9 can be docked with the second docking sleeve 83 for fixation. The loading component 9 is used for secondary placement of traditional Chinese medicine powder and collection of ground medicine powder.

[0046] When the grinding cylinder 42 needs to grind the Chinese medicine raw materials, the loading assembly 9 needs to be assembled on the front side of the drainage cabin 81 through the second docking sleeve 83 to keep the relay cabin 52 and the drainage cabin 81 in a closed state when the grinding cylinder 42 grinds the raw materials; if the ground medicine powder needs to be taken out from the grinding cylinder 42, the electric push rod 62 can be controlled to drive the closing cylinder 63 to move upward, so that the closing cylinder 63 opens the space between the grinding cylinder 42, the relay cabin 52 and the drainage cabin 81 to communicate with each other, and the closing cylinder 63 keeps the suction tube 71 in a closed state. At this time, the opening structure of the relay cabin 52 is interconnected with the through-hole structure of the drainage cabin 81, and then the medicine powder can be taken out through the electric push rod 62. The grinding cylinder 42 and the assembled relay cabin 52 and its accessories are rotated by the connecting shaft 3, so that the drainage cabin 81 is in a vertical downward direction, and then the grinding cylinder 42 is shaken by the connecting shaft 3, so that the powder in the grinding cylinder 42 passes through the relay cabin 52 and is blocked by the closing cylinder 63 and guided to fall into the drainage cabin 81, and then falls into the loading assembly 9 through the drainage cabin 81 for centralized collection. After the powder collection is completed, the operation of the closing cylinder 63 can be controlled to open the connection between the suction tube 71 and the relay cabin 52, so that the flying powder in the relay cabin 52, the drainage cabin 81 and the grinding cylinder 42 can be sucked out, and the flying powder can be sucked out After completion, the loading assembly 9 can be withdrawn vertically downward through the second docking sleeve 83, thereby completing the collection of the ground powder, and ensuring that no powder will fly into the ambient space to pollute the air when the collected powder is dumped; if the initially ground powder needs to be re-ground to increase the fineness of the powder, the drainage cabin 81 can be placed in a vertical downward direction as described above, and the powder to be re-ground can be placed in the loading assembly 9, and then the loading assembly 9 can be vertically assembled on the drainage cabin 81, and the sealing ring 82 will ensure that the space between the loading assembly 9 and the drainage cabin 81 is closed from the outside space, and then the connecting shaft 3 can be rotated to make the grinding cylinder 42 The grinding cylinder 42 is reset to allow the powder in the loading assembly 9 to fall into the grinding cylinder 42. At the same time, the grinding cylinder 42 can be shaken to allow the powder at the loading assembly 9 to completely fall into the grinding cylinder 42. Subsequently, the electric push rod 62 can be operated to drive the closing cylinder 63 to close the grinding cylinder 42 for secondary grinding, so that the feeding process before the secondary grinding of the powder will not generate flying powder and float in the environmental space; in this way, by operating the angle of the grinding cylinder 42 and then changing the angle of the drainage cabin 81, the grinding cylinder 42 can be placed in a closed space during the feeding and unloading processes, so as to ensure that the powder will not generate flying powder and float in the environmental space in the steps before and after the grinding process.

[0047] like Figure 12-16As shown, the loading assembly 9 includes an end cover 91, a loading cylinder 92 and a second docking locking member 93. The end cover 91 is arranged on the front side of the drainage cabin 81. The end cover 91 is a structure with limiting teeth. The limiting tooth structure of the end cover 91 is disposed with a loading cylinder 92. The loading cylinder 92 can contact the sealing ring 82 to achieve a sealed assembly. The end cover 91 is fixedly connected with second docking locking members 93 on both sides. The second docking locking members 93 are fastening bolts. The second docking locking members 93 respectively correspond to the positions of the adjacent second docking sleeves 83, and the second docking locking members 93 cooperate with the second docking sleeves 83.

[0048] The cooperation between the second docking locking piece 93 and the second docking sleeve 83 can be disassembled and docked when the drainage cabin 81 is in a vertically downward state, so that the end cover 91 and the loading cylinder 92 can be docked and withdrawn from the drainage cabin 81 vertically downward; after the powder is ground, the powder will fall into the loading cylinder 92 for collection; when the powder needs to be ground for the second time, the powder can be placed in the loading cylinder 92, and the loading cylinder 92 can be placed between the limiting tooth structure of the end cover 91, and then the end cover 91 can be assembled on the drainage cabin 81.

[0049] like Figure 7 As shown, a servo motor 10 is also included. The servo motor 10 is fixedly connected to the left side of the fixed frame 2. The output shaft of the servo motor 10 is connected to the connecting shaft 3. The servo motor 10 is a model with a self-locking reduction mechanism. The servo motor 10 is a servo sensor system with angle sensing.

[0050] By controlling the operation of the servo motor 10, the grinding cylinder 42 can be rotated at the angle and speed set by the servo program, so as to drive the grinding cylinder 42 to shake to increase the degree of raw material participation in grinding and improve the degree of grinding uniformity; to drive the grinding cylinder 42 to rotate to a set angle to perform other operations; to drive the grinding cylinder 42 to perform high-frequency vibration to cause the powder adhering to the tube wall of the device to fall off.

[0051] Further description, the left and right side walls of the relay cabin 52 and the drainage cabin 81 are structures embedded with tempered glass.

[0052] The structure in which the left and right side walls of the relay cabin 52 and the drainage cabin 81 are embedded with tempered glass allows personnel to conveniently observe the state of the powder in the inner space.
