Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine processing, in particular to a traditional Chinese medicine processing and crushing device with easy-to-replace blades. Background Art

[0002] During the processing of traditional Chinese medicine, it is usually necessary to crush the Chinese herbal medicine slices to obtain powdered medicine. The powder is generally used to make Chinese medicine dosage forms such as powders, pills, tablets, and suspended granules. Most of the existing crushing methods use high-speed rotating blades to crush the Chinese herbal medicine slices. However, the sharpness of the blades decreases after being used for a period of time. Especially when the grinder is used for a long time, the frequency of blade replacement and maintenance needs to be increased. The existing replacement method usually involves disassembling the entire blade and then replacing the blade. This method of blade replacement is more complicated and has low replacement efficiency. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a Chinese medicine processing and crushing device with easy replacement of blades, so as to solve the existing replacement method of usually disassembling the entire blade before replacing the blade. This method of blade replacement is relatively complicated and has low replacement efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a traditional Chinese medicine processing and crushing device that is easy to replace blades, comprising a crushing chamber and a knife seat, a driving motor is installed below the crushing chamber, and a driving shaft is connected to the top of the driving motor, a knife seat is installed through the driving shaft, a cutting protrusion is integrally formed on the outer side of the knife seat, a guide rod is integrally formed above the knife seat, and an expansion spring is connected to the top of the guide rod, an installation slot is provided on the knife seat, a bottom blade, a crushing straight blade and an upper blade are sequentially inserted and installed in the middle part of the knife seat, and a fixing nut is threadedly connected to the top of the drive shaft.

[0005] The beneficial effects of the present invention are as follows: the fixing nut is unscrewed, and the spring is expanded to push the knife seat to expand. After expansion, the mounting slot is disengaged from the blade, and the blade to be replaced can be taken out as needed, and then the blade can be installed inside the mounting slot. This replacement method can replace the blade at a fixed point without completely disassembling the blade, which simplifies the steps of blade replacement and ensures replacement efficiency.

[0006] To facilitate sealing of the device:

[0007] As a further improvement of the above technical solution: the top of the crushing chamber is connected to a cover plate via a hinge, and a locking bolt is installed on the side of the cover plate away from the hinge, and a support frame is provided on the outside of the crushing chamber.

[0008] The beneficial effect of this improvement is that the cover can be opened and closed easily by the hinge in conjunction with the locking bolt, thereby ensuring the airtightness of the device when in use.

[0009] To increase crushing efficiency:

[0010] As a further improvement of the above technical solution: the cutting protrusions are circumferentially distributed on the outer side of the tool holder.

[0011] The beneficial effect of this improvement is that the circumferentially distributed cutting bumps can assist the blades in crushing the Chinese herbal medicine slices, thereby increasing the crushing efficiency of the device.

[0012] To facilitate the fixing of the blade:

[0013] As a further improvement of the above technical solution: a through hole is formed on one end of the bottom blade, the crushing straight blade and the upper blade close to the blade seat.

[0014] As a further improvement of the above technical solution: a cylindrical protrusion is integrally formed on the installation slot.

[0015] The beneficial effect of this improvement is that the through holes on the bottom blade, the crushing straight blade and the upper blade can cooperate with the cylindrical protrusions to form a limit when the blade holder clamps the blade, fix the position of each blade, and ensure the stability of the blade when in use.

[0016] To facilitate the insertion of the knife holder:

[0017] As a further improvement of the above technical solution: the guide rod is symmetrically arranged about the center line of the tool holder.

[0018] The beneficial effect of this improvement is that the symmetrically arranged guide rods can guide the tool holder during installation, thereby facilitating the installation of the tool holder.

[0019] To facilitate the deployment of the knife block:

[0020] As a further improvement of the above technical solution: the guide rod and the expansion spring are arranged with their axes coincident.

[0021] The beneficial effect of this improvement is that the expansion springs arranged with the axes coinciding can push the guide rod and thus drive the knife holder to expand.

[0022] To increase the sealing of the device:

[0023] As a further improvement of the above technical solution: a sealing ring is installed at the connection between the cover plate and the crushing chamber.

[0024] The beneficial effect of this improvement is that the sealing ring can ensure the sealing of the connection between the cover plate and the crushing chamber, thereby preventing the crushed traditional Chinese medicine powder from escaping. BRIEF DESCRIPTION OF THE DRAWINGS
