Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See Figure 1-Figure 3 , a drug crushing and grinding device, comprising:

[0030] The crushing assembly is configured to preliminarily crush the medicinal materials, and includes a crushing box 4 with a conical feed inlet 1 above the crushing box 4, a crushing body, and a crushing channel for the medicinal materials;

[0031] Specifically, the crushing body of the crushing assembly is two crushing rollers 3 arranged in parallel and rotating in opposite directions. Crushing teeth 2 are provided on the outer walls of the two crushing rollers 3. The crushing teeth 2 are raised structures and are used for preliminary crushing of medicinal materials. After the medicinal materials are placed between the two crushing rollers 3, they can be crushed by the two crushing rollers 3, and the crushed medicinal materials fall down from between the two crushing rollers 3. The power source of the two crushing rollers 3 can be two meshing gears set outside the crushing box 4. The gears are respectively connected to the crushing rollers 3, and one of the crushing rollers 3 is connected to the motor. This structure belongs to the conventional structure of the "double-roller crushing equipment" in the prior art and will not be elaborated here.

[0032] Among them, the purpose of setting up the crushing component is to preliminarily crush some large pieces of medicinal materials with long strips and other structures, so as to facilitate transportation on the one hand, and on the other hand, to facilitate small pieces of materials to enter the gap between the upper grinding disk 12 and the lower grinding disk 16, making full preparations for subsequent grinding.

[0033] The feed assembly has a feed channel connected to the grinding channel. It is used to transport the initially ground medicinal materials at a specific speed. The purpose is to match the grinding speed to avoid the grinding area being too full of medicinal materials and unable to grind, and to avoid the grinding area being too empty of medicinal materials and resulting in waste of resources.

[0034] Specifically, the feeding channel of the feeding assembly is a horizontal cylindrical structure, and the medicinal materials dropped from the upper crushing channel can enter the feeding channel. The feeding channel is provided with a spiral blade 7 that is horizontally arranged and rotatable as a whole, and the spiral blade 7 can be used to transport the medicinal materials horizontally.

[0035] Specifically, it also includes a feeding box 5, which is connected to the crushing box 4. A horizontally arranged transmission shaft 6 is installed inside the feeding box 5, and a spiral blade 7 is fixed on the outer wall of the transmission shaft 6. One end of the transmission shaft 6 extends to the outside of the feeding box 5 and is connected to a feeding motor 8 installed outside the feeding box 5.

[0036] Specifically, a discharge port 9 is provided at a lower position at the end of the feeding box 5 , and the medicinal materials transported by the spiral blades 7 can move to the discharge port 9 and fall downward along the discharge port 9 .

[0037] More specifically, the spiral blades 7 and the feeding motor 8 can be used to regularly and purposefully convey the material at a certain speed, thereby avoiding the problem of poor grinding effect caused by the medicinal materials directly entering the grinding area after being crushed.

[0038] The grinding assembly has a grinding channel connected to the feeding channel, including an upper grinding disc 12 and a lower grinding disc 16 that are coaxially arranged and can rotate relative to each other. There is a gap between the upper grinding disc 12 and the lower grinding disc 16 for grinding the medicinal materials and discharging them to the surrounding area. The size of the gap gradually decreases from the center direction of the upper grinding disc 12 to the circumferential edge direction;

[0039] Among them, the grinding component also includes a discharge port 19, which enables the medicinal materials to be continuously fed and ground inside the crushing and grinding device, and during the grinding process, the ground powder can be discharged outward from the discharge port 19 as soon as possible, which is used to replace the blade grinding structure in the existing technology, solves the problem that the medicinal material powder must be shut down during the discharge process, and improves work efficiency.

[0040] Specifically, the grinding assembly includes a grinding box 14, and a sound insulation layer 1402 is provided inside the grinding box 14. More specifically, the grinding box 14 also includes an outer layer 1401 and an inner layer 1403. The sound insulation layer 1402 is located between the outer layer 1401 and the inner layer 1403. The outer layer 1401 and the inner layer 1403 are both made of metal, such as stainless steel. The sound insulation layer 1402 can be sound insulation cotton, which is mainly used to avoid excessive noise generated during the grinding process. The grinding box 14 is located below the feeding box 5, and the upper grinding disc 12 and the lower grinding disc 16 are located inside the grinding box 14. A feeding chamber 11 connected to the feeding channel of the feeding assembly is provided in the middle position of the upper grinding disc 12. The medicinal materials entering the feeding chamber 11 can enter the gap formed between the upper grinding disc 12 and the lower grinding disc 16. Since the size of the gap gradually decreases from the middle to the surrounding direction, the medicinal materials can be ground step by step from large to small, avoiding the problem of jamming, and having the advantage of good grinding quality. The upper grinding disc 12 is fixedly mounted on the raised mounting surface 21 inside the grinding box 14, and a gasket 13 is installed between the upper grinding disc 12 and the mounting surface 21. In practice, gaskets 13 of different thicknesses can be installed between the mounting surface 21 and the upper grinding disc 12, so that the position of the upper grinding disc 12 can be adjusted, thereby adjusting the gap between the upper grinding disc 12 and the lower grinding disc 16, so as to control the size of the ground particles; a trumpet-shaped feeding plate 10 is installed on the top of the upper grinding disc 12, which is used to allow the medicinal materials discharged from the discharge port 9 to completely enter the interior of the grinding box 14.

[0041] Specifically, the lower surface cross-section of the upper grinding disc 12 is an inwardly concave arc structure, and the upper surface cross-section of the lower grinding disc 16 is an arc structure with a center convex upward, so that after the medicinal materials fall on the lower grinding disc 16, they can move around along the arc structure, thereby avoiding the ground medicinal materials from staying too long in the gap between the upper grinding disc 12 and the lower grinding disc 16, which helps to improve work efficiency.

[0042] Specifically, a grinding motor 18 is installed at the bottom of the grinding box 14, and the lower end of the lower grinding disc 16 is connected to the grinding spindle 15. The grinding motor 18 is connected to the grinding spindle 15. The grinding motor 18 can adopt a servo motor, which can realize speed adjustment to meet the grinding needs of different scenarios.

[0043] Specifically, a material guide inclined plate 17 is installed at the bottom of the grinding box 14, and the discharge port 19 is located on one side of the bottom of the grinding box 14 and close to the lowest point of the material guide inclined plate 17, so that the ground medicinal materials move downward along the material guide inclined plate 17 and are finally discharged from the discharge port 19.

[0044] Specifically, the lower surface of the upper grinding disc 12 and the upper surface of the lower grinding disc 16 are both provided with outwardly protruding grinding protrusions 20 for grinding medicinal materials between the two to improve the grinding quality.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
