[0028] The motor 7 drives the rotating grinding head 6 to rotate, and cooperates with the feeding hopper 3 to feed materials, so that the rotating grinding head 6 and the fixed grinding head 4 can grind the input Chinese medicine particles conveniently, reduce the use of manpower, and improve the grinding efficiency.

[0029] The upper cover chamber 2 and the grinding chamber 1 are fixedly installed by connecting flanges 8 and fixing bolts 9, so that they can be easily disassembled, thereby facilitating internal cleaning and maintenance of the upper cover chamber 2 and the grinding chamber 1.

[0030] A connecting tube 10 is fixedly connected to the circumference of the bottom surface of the grinding chamber 1, and the bottom end of the connecting tube 10 is fixedly connected to a collecting chamber 11. A mesh tube 12 is fixedly connected to the bottom surface of the collecting chamber 11. The setting of the mesh tube 12 pads the bottom of the collecting chamber 11 to facilitate the installation of the negative pressure fan 19 and facilitate ventilation.

[0031] A support ring 14 is fixedly connected to the inner side of the lower part of the collecting chamber 11, and threaded columns 15 are evenly fixedly connected to the support ring 14. A frame 16 is provided above the support ring 14. The threaded columns 15 penetrate the frame 16 and are threadedly connected to a hand-tightened nut 17.

[0032] A negative pressure fan 19 is fixedly mounted on the bottom surface of the collecting chamber 11 , and an air inlet of the negative pressure fan 19 is communicated with the collecting chamber 11 .

[0033] The negative pressure fan 19 generates negative pressure suction, and the powder generated by grinding is continuously sucked into the dust filter bag 18 for collection, which effectively prevents the powder from diffusing during the processing and affecting the surrounding environment. At the same time, the negative pressure suction facilitates the ground powder to enter the collection chamber 11 from the grinding chamber 1.

[0034] See also Figure 3 A scraper 13 is fixedly connected to the outer side of the rotating grinding head 6 , and the scraper 13 is in contact with the inner wall of the grinding chamber 1 .

[0035] By setting the scraper 13 , the scraper 13 is driven to clean the inner wall of the grinding chamber 1 synchronously during the rotation of the rotating grinding head 6 , so that the ground powder can fall into the collecting chamber 11 through the connecting pipe 10 .

[0036] See also Figure 4 A grinding gap is provided between the fixed grinding head 4 and the rotating grinding head 6, and a gasket 20 is provided between the connecting flanges 8. There are five types of gaskets 20, and the thicknesses of the five types of gaskets 20 are 0.01mm, 0.02mm, 0.03mm, 0.04mm, and 0.05mm, respectively.

[0037] By setting the gasket 20, the installation gap between the upper cover cavity 2 and the grinding cavity 1 can be increased, so as to control the grinding gap between the fixed grinding head 4 and the rotating grinding head 6, so as to adapt to the requirements of different coarse and fine grinding.

[0038] See also Figure 5 An opening is provided on the front side of the collecting chamber 11, and a sealing plate 21 is provided on the outer side of the opening. The sealing plate 21 is fixedly installed with the collecting chamber 11 by means of mounting bolts 23.

A switch 22 is fixedly installed on the outer wall of the collecting chamber 11, and the motor 7 and the negative pressure fan 19 are electrically connected to the switch 22 through a wire, and the switch 22 is externally connected to a power supply.

[0039] The upper part of the collecting chamber 11 can be opened by setting the sealing plate 21, and the frame 16 can be disassembled by cooperating with the threaded column 15 and the hand-tightening bolt 17, so that the dust filter bag 18 can be removed conveniently, thereby facilitating the material removal.

[0040] The working principle of the utility model is:

[0041] During use, the motor 7 and the negative pressure fan 19 are started through the switch 22, the motor 7 drives the rotating grinding head 6 to rotate, and the negative pressure fan 19 drives the air to circulate through the feeding hopper 3, the feed port 5, the grinding gap, the connecting pipe 10, the collecting chamber 11, the dust filter bag 18 and the mesh tube 12. At this time, the medicinal material particles to be ground are put into the feeding hopper 3 on the upper cover cavity 2, and the medicinal material falls into the feed port 5. The fallen medicinal material is ground by the rotating grinding head 6 and the fixed grinding head 4. At this time, the ground powder is driven by the flowing air into the dust filter bag 18 for filtration, thereby collecting the powder.

[0042] During use, the grinding head 6 is rotated to drive the scraper 13 to continuously clean the inner wall of the grinding chamber 1, so that the Chinese medicine powder can be easily dropped from the connecting tube 10.

[0043] When in use, the fixing bolts 9 are removed, the required gaskets 20 are placed between the connecting flanges 8, and then installed through the fixing bolts 9, so as to control the grinding gap between the fixed grinding head 4 and the rotating grinding head 6.

[0044] After using for a period of time, the mounting bolts 23 on the sealing plate 21 can be removed to open the upper part of the collecting chamber 11, and the hand nut 17 can be unscrewed to remove the frame 16, thereby taking out the dust filter bag 18 and the ground Chinese medicine powder.
