Detailed implementation manners

[0030] The following will describe in detail the specific implementation manners of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific implementation manners.

[0031] As Figures 1 to 4 shown, a traditional Chinese medicine crushing device provided by an embodiment of the present invention includes a first support frame 1, and a crushing cylinder 2 is rotatably arranged on the first support frame 1. As Figure 3 shown, a crushing mechanism 4 for crushing materials is arranged inside the crushing cylinder 2. The crushing mechanism 4 includes a motor 401 fixedly arranged on the crushing cylinder 2. The output end of the motor 401 is fixedly connected to a transmission shaft 402, and a blade 403 for crushing materials is fixedly connected to the lower side surface of the transmission shaft 402. When the motor 401 is started, it drives the transmission shaft 402 to rotate, and the transmission shaft 402 drives the blade 403 to crush the materials. A material lifting plate 404 is fixedly connected to the lower end of the transmission shaft 402. The upper and lower surfaces of the material lifting plate 404 are arc-shaped, and one side is obliquely attached to the bottom of the crushing cylinder 2. When the transmission shaft 402 rotates, it will drive the material lifting plate 404 to rotate. The rotation of the material lifting plate 404 will use the arc-shaped top to strike the materials, and the materials will move up along the top of the material lifting plate 404, so that it is more convenient for the blade 403 to crush the materials and avoid the accumulation of materials at the bottom.

[0032] The lower end of the crushing cylinder 2 is connected to a gas transmission mechanism 3. As Figure 4 shown, the gas transmission mechanism 3 includes a pipe connecting cylinder 302 fixedly arranged at the bottom of the crushing cylinder 2. An air supply port 303 communicating with the crushing cylinder 2 is opened inside the pipe connecting cylinder 302. An air supply spray cylinder 304 is fixedly arranged inside the air supply port 303. The top of the air supply spray cylinder 304 is sealed, and a plurality of groups of spray ports 305 are circumferentially opened on the side surface. A one-way valve is arranged inside each group of spray ports 305. High-pressure gas is output to the bottom of the crushing cylinder 2 through the spray ports 305, and the one-way valve is used to prevent powdery materials from entering the inside of the spray ports 305, so as to maintain the through state of the spray ports 305. The one-way valve can be a ball-type one-way valve. The ball-type one-way valve has a movable sphere inside. The forward air flow pushes the sphere away from the valve seat to conduct, and the reverse pressure or spring makes the sphere reset to block, which belongs to the prior art. A limiting ring 306 is fixedly arranged at the lower end of the air supply spray cylinder 304, and the limiting ring 306 is fixed inside the pipe connecting cylinder 302. AsFigure 4 As shown. One end of the pipe joint 302 away from the crushing cylinder 2 is connected with an air delivery pipe 301. In addition, a notch that is mutually adapted to the shape of the air delivery nozzle 304 is formed at one end of the material lifting plate 404 close to the air delivery nozzle 304, so as to reduce the possibility of materials hiding at the upper end of the air delivery nozzle 304.

[0033] A heating assembly for changing the temperature of the air flow is arranged on the air delivery pipe 301. In this embodiment, the heating assembly includes a metal pipe 7 connected to the air delivery pipe 301, and an electromagnetic heater 9 for heating the metal pipe 7 is fixedly arranged on the metal pipe 7. By heating the metal pipe 7 with the electromagnetic heater 9, the air flow inside the metal pipe 7 is heated. Those skilled in the art can select the size of the hot metal pipe 7 as needed to ensure that the air flow can be fully heated. And other heating assemblies that can realize heating the air flow all fall within the protection scope of this patent.

[0034] In order to prevent the crushing cylinder 2 from rotating due to the vibration generated during crushing, which increases the difficulty for the staff to control the crushing cylinder 2, a connecting plate 101 is fixedly arranged on the first support frame 1, a positioning bolt 102 is threadedly connected to the connecting plate 101, and a positioning groove 201 adapted to the positioning bolt 102 is formed on the crushing cylinder 2. By inserting the positioning bolt 102 into the positioning groove 201, the positioning of the crushing cylinder 2 is realized, and the stable state of the crushing cylinder 2 during crushing is maintained.

[0035] A second support 11 is arranged on one side of the first support frame 1, a second dust collection pipe 6 is fixedly arranged on the second support 11, and the input end of the second dust collection pipe 6 is communicated with the first dust collection pipe 5 or the input end of the second dust collection pipe 6 is communicated with the first dust collection pipe 5 through other components, all of which fall within the protection scope of this patent. The output end of the second dust collection pipe 6 is connected with a dust collection bag 8. The material particles will be blown into the first dust collection pipe 5 and the second dust collection pipe 6 under the action of the air flow, and finally enter the dust collection bag 8, realizing the collection of materials.

[0036] In another specific embodiment, a positioning cylinder 10 is placed at the inner bottom of the second support 11, as Figure 1 and Figure 4 shown. The dust collection bag 8 is located above the center of the positioning cylinder 10. During material collection, the staff places the storage bag inside the positioning cylinder 10, sends the lower end of the dust collection bag 8 into the storage bag, and unties the binding at the lower end of the dust collection bag 8. The materials inside the dust collection bag 8 will fall into the storage bag, realizing the material collection operation. The positioning cylinder 10 can limit the spilling range of the materials, thus facilitating the recycling of the materials and the maintenance of the environment.

[0037] In a specific embodiment, an air pump is connected to the other end of the metal tube 7. The air pump is used to convey gas to the metal tube 7 and the gas transmission pipe 301, so as to transport the material particles that have been crushed to a certain extent inside the collision and crushing cylinder 2 through the collision of airflows, enabling the airflows to drive the material particles into the dust collection bag 8, that is, realizing the collection of the crushed materials.

[0038] In a specific embodiment, since the surface area of the medicinal materials increases after crushing, the active ingredients (such as phenols and flavonoids) exposed to the air are more likely to undergo oxidation reactions. At this time, it is necessary to ensure that the material particles are in contact with oxygen as little as possible. In this embodiment, a nitrogen delivery device is connected to the other end of the metal tube 7. The nitrogen delivery device is used to convey nitrogen gas to the metal tube 7 and the gas transmission pipe 301, so as to squeeze out the oxygen in the collision and crushing cylinder 2, the dust collection bag 8 and each pipeline as much as possible, reduce the possibility of the material particles contacting oxygen, and thus improve the crushing effect.

[0039] This patent also provides a method for using the Chinese medicine collision and crushing device, including the following steps:

[0040] S1. Turn on the gas transmission device. The gas output by the gas transmission device sequentially passes through the metal tube 7, the gas transmission pipe 301, the pipeline joint 302 and the air supply spray tube 304, and finally enters the collision and crushing cylinder 2 through the spray port 305;

[0041] S2. It is necessary to judge whether to heat the materials during the crushing process: If heating is required, turn on the electromagnetic heater 9 to heat the metal tube 7, and heat the internal airflows through the metal tube 7. After preheating the collision and crushing cylinder 2 for a period of time, the materials can be fed; When heating is not required, the electromagnetic heater 9 does not need to be turned on;

[0042] S3. After feeding the materials into the interior of the collision and crushing cylinder 2, close the opening of the collision and crushing cylinder 2, and turn on the motor 401 to realize the crushing of the materials;

[0043] S4. The airflows will drive the material particles that have been crushed into the interior of the dust collection bag 8, realizing the collection of the materials. The staff puts the lower end of the dust collection bag 8 into the interior of the storage bag, and opens the binding opening at the lower end of the dust collection bag 8. The materials inside the dust collection bag 8 will fall into the interior of the storage bag, realizing the material collection operation.

[0044] Working principle: When in use, turn on the gas delivery device. The gas output by the gas delivery device successively passes through the metal pipe 7, the gas delivery pipe 301, the pipe adapter 302, and the air supply nozzle 304, and finally enters the crushing cylinder 2 through the nozzle 305. The staff judges whether to heat the materials during the crushing process according to needs: If heating is required, turn on the electromagnetic heater 9 to heat the metal pipe 7, and heat the internal air flow through the metal pipe 7. After preheating the crushing cylinder 2 for a period of time, the materials can be fed. The flowing air flow can accelerate the heat transfer inside the crushing cylinder 2, making the heat more evenly distributed; when heating is not required, the electromagnetic heater 9 does not need to be turned on, and the air flow drives the heat generated during the crushing process to improve the cooling effect.

[0045] After feeding the materials into the crushing cylinder 2, close the opening of the crushing cylinder 2, turn on the motor 401. The motor 401 drives the transmission shaft 402 to rotate, and the transmission shaft 402 drives the blade 403 to crush the materials. The rotation of the transmission shaft 402 will drive the material lifting plate 404 to rotate, and the rotation of the material lifting plate 404 will use the arc-shaped top to strike the materials. The materials move upward along the top of the material lifting plate 404, which is more convenient for the blade 403 to crush the materials and avoid the accumulation of materials at the bottom.

[0046] When the materials are crushed into flour-like particles, the air flow will drive the material particles to move upward, enter the first dust collection pipe 5 and the second dust collection pipe 6, and finally enter the inside of the dust collection bag 8 to realize the collection of the materials.

[0047] The gas delivery device can be replaced with a nitrogen delivery device, and nitrogen gas is delivered to the metal pipe 7 and the gas delivery pipe 301 through the nitrogen delivery device, so as to squeeze out the oxygen in the crushing cylinder 2, the dust collection bag 8 and each pipeline as much as possible, and reduce the possibility of oxidation reaction of the active ingredients exposed to the air due to the increased surface area of the medicinal materials after crushing.

[0048] The above only discloses several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
