[0024] Reference Figure 1-Figure 5 , a self-circulating grinding equipment, including an outer shell 1, an inner shell 2 is fixedly inserted through the top of the outer shell 1, and multiple movable wheels 3 are rotatably connected to the inner walls of both sides of the outer shell 1, and the same annular cover 4 is arranged between the multiple movable wheels 3, and the top of the annular cover 4 passes through the inner shell 2, and the outer surface of the annular cover 4 is provided with two annular grooves 5, and the multiple movable wheels 3 roll in the corresponding annular grooves 5 respectively, and the outer surface of the annular groove 5 is clamped with multiple filter screens 6, and the inner surface of the annular cover 4 is fixed with multiple limit frames 7 by bolts. The cross-section of the limit frame 7 is a Y-shaped structure, and the outer surface of the annular groove 5 is fixed with a driven gear 8, and the inner surface of the inner shell 2 is fixed with a support frame 9 by bolts. The upper surface of the support frame 9 An inner motor 10 is fixed to the surface by bolts, a grinding block 11 is fixed to the output end of the inner motor 10 by bolts, an outer motor 12 is fixed to the top of the inner wall of the outer shell 1 by bolts, and a driving gear 13 is keyed to the output end of the outer motor 12, and the driving gear 13 is meshed with the driven gear 8. The rotatable design of the annular cover 4 can transport the unground raw materials to the inner shell 2 again with the cooperation of the limit frame 7, and the raw materials are re-ground by the rotating grinding block 11. The way of rotating the raw materials by the annular cover 4 can avoid the residue of raw materials in the annular cover 4, and avoid the blockage of the annular cover 4, thereby ensuring the cyclic grinding operation of the solid beverage raw materials by the grinding equipment.

[0025] Among them, a feed hopper 14 is fixed to the top of the inner shell 2 by bolts, and the bottom end of the feed hopper 14 is located on one side of the inner motor 10. The feed hopper 14 can guide the feed of the raw materials before grinding.

[0026] At the same time, the inner surface of the inner shell 2 is fixed with an upper material guide cover 15 and a lower material guide cover 16 by bolts, and a storage box 17 is placed at the bottom of the inner wall of the outer shell 1, and the positions of the lower material guide cover 16 and the storage box 17 correspond to each other. Through the design of the upper material guide cover 15, the raw materials falling from the annular cover 4 can be guided to avoid the overflow of the raw materials, and ensure that the raw materials can be concentrated and discharged to the grinding block 11, so that the raw materials can be fully re-grinded, and the lower material guide cover 16 can guide the raw materials filtered out of the filter screen 6, which is convenient for centralized storage in the storage box 17.

[0027] The outer wall of one side of the shell 1 is sealed with a sealing door 18.

At this time, under the action of the inner motor 10, the grinding block 11 is driven to rotate, so that the raw materials fall between the grinding block 11 and the inner shell 2. The rotation of the grinding block 11 is the grinding of the raw materials, and the ground raw materials will be discharged through the bottom of the inner shell 2 and fall into the annular cover 4. The annular cover 4 filters the ground raw materials, and the qualified raw materials pass through the filter screen 6 and pass through the guide of the lower guide cover 16. , gathered in the storage box 17; at this time, due to the start-up of the external motor 12, the annular cover 4 will rotate between the multiple movable wheels 3 under the action of the transmission of the driving gear 13 and the driven gear 8, and the unfiltered raw materials will remain in the annular cover 4, and when the annular cover 4 rotates, the limiting frame 7 can limit the raw materials in the annular cover 4 until the raw materials are transferred to the top of the annular cover 4. At this time, the raw materials will fall under the guidance of the limiting frame 7, and the grinding block 11 can re-grind the raw materials. This is repeated, that is, the raw materials can be self-circulated and ground to ensure the quality of the solid beverage grinding output. The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and its utility model concept of the present invention, which should be covered within the protection scope of the present invention.
