[0038] The specific working process is as follows:

[0039] The present application is divided into the feeding stage, the grinding stage and the discharging stage according to the working stages of the grinding equipment; and the feeding stage, the grinding stage and the discharging stage are respectively described, and the specific description process is as follows:

[0040] First step, the feeding stage:

[0041] The staff kill and dry the tea leaves before grinding, so as to remove the water in the tea leaves, and then transport the dried tea leaves to the surrounding of the tea grinding equipment. In the case of loosening the bolt 23, the grinding cylinder 1 is controlled to rotate between the two supports 21. When the first cavity 14 is located directly above the second cavity 15, the movable disc 3 in the first cavity 14 is close to and in contact with the grinding body 12, and the movable disc 3 in the second cavity 15 is away from the grinding body 12, so that the space between the grinding body 12 and the movable disc 3 in the second cavity 15 is maximized. The movable disc 3 is lower than the corresponding material door 19 of the second cavity 15 in the vertical direction. Tighten the bolt 23 to increase the friction between the rotating block 16 and the rotating sleeve 22, so that the grinding cylinder 1 is locked on the support 21. Then open the corresponding material door 19 of the second cavity 15, so that the material port 18 is opened. Then the staff pours tea into the grinding cylinder 1. In order to prevent the tea poured into the grinding cylinder 1 from leaking out, the material port 18 can also be controlled to be inclined upward, and the first cavity 14 can be kept above the second cavity 15. After the tea is poured into the second cavity 15 along the corresponding material port 18 of the second cavity 15, the material door 19 of the corresponding material port 18 of the second cavity 15 is closed. The material door 19 can seal the material port 18 after being closed. The material door 19 is adapted to the inner wall of the grinding cylinder 1. Then loosen the bolt 23, push the grinding cylinder 1 to rotate between the two supports 21, and tighten the bolt 23 after the second cavity 15 is located directly above the first cavity 14.

[0042] Second step, grinding stage:

[0043] The two movable discs 3 in the grinding cylinder 1 move downward under the action of their own gravity. During the downward movement of the movable disc 3 in the first cavity 14, the gas below the movable disc 3 is compressed, so that the gas below the movable disc 3 in the first cavity 14 is pressed into the second cavity 15 above the movable disc 3 along the side pipe 4. The gas pushes the movable disc 3 in the second cavity 15 to move downward. Similarly, the movable disc 3 in the second cavity 15 also moves downward under the action of its own gravity, so that the movable disc 3 in the second cavity 15 moves downward under the double action of gravity and gas pressure. The movable disc 3 in the second cavity 15 compresses the gas and tea material below, so that the material in the second cavity 15 is close to the grinding body 12 during the compression of the movable disc 3 and under the action of its own gravity. In the case that the second cavity 15 is located directly above the first cavity 14, the motor 13 is controlled to rotate by the controller. The rotating motor 13 drives the connected rotating shaft 5 to rotate. Since the movable hole 31 of the movable disc 3 is connected with the sliding strip 51 on the outer wall of the rotating shaft 5 through the sliding groove 32, the rotating shaft 5 rotates to drive the movable disc 3 and the grinding body 12 to rotate. The grinding body 12 rotates relative to the grinding sleeve 11, thereby grinding the tea in the grinding gap 17. The movable disc 3 in the second cavity 15 rotates with the rotating shaft 5. The movable disc 3 in the second cavity 15 drives the push bar 37 close to the grinding body 12 to rotate. The push bar 37 drives the material to move during the rotation of the movable disc 3 in the second cavity 15, so that the material moves close to the inner wall of the grinding cylinder 1 under the centrifugal force during the pushing of the push bar 37, and the grinding gap 17 is close to the inner wall of the grinding cylinder 1. Therefore, the push bar 37 can accelerate the material to move towards the grinding gap 17, thereby improving the grinding efficiency. In addition, as the material in the second cavity 15 is ground, the movable disc 3 in the second cavity 15 gradually moves close to the grinding body 12. The movable disc 3 in the second cavity 15 compresses the tea and gas below, so that the gas drives the tea to flow towards the grinding gap 17, thereby further improving the grinding efficiency.

[0044] And the movable disc 3 in the first cavity 14 will push away the gas below under the action of gravity, and in the case that the movable disc 3 in the second cavity 15 stops moving downward, the movable disc 3 in the first cavity 14 can still move downward, so that the negative pressure is formed between the movable disc 3 in the first cavity 14 and the grinding body 12, the gravity center of the spherical shell 6 is lowered under the action of the gravity block 61, so the one-way hole 62 on the spherical shell 6 is always in a vertical state, and the upper end of the one-way hole 62 can move downward in one direction to discharge from the lower end in the vertical state, so that the gas above the movable disc 3 in the second cavity 15 can pass through the corresponding one-way hole 62 into the space between the movable disc 3 and the grinding body 12 in the second cavity 15, and then flow along the grinding gap 17 into the first cavity 14; after the movable disc 3 in the first cavity 14 moves to the limit position, the rotation of the rotating shaft 5 will drive the movable disc 3 in the first cavity 14 and the connected movable block 33 to rotate, the movable block 33 in the first cavity 14 will contact with the fixed block 34 during the rotation around the rotating shaft 5, the movable block 33 in the first cavity 14 will drive the movable disc 3 to move upward under the extrusion of the fixed block 34, the movable disc 3 in the first cavity 14 will move close to the movable disc 3 in the second cavity 15, and the gas pressure will increase when the distance between the two movable discs 3 decreases, so that the gas between the movable disc 3 in the first cavity 14 and the grinding body 12 will flow out along the one-way hole 62 on the spherical shell 6 in the first cavity 14, and the space below the movable disc 3 in the first cavity 14 will form a negative pressure during the upward movement of the movable disc 3, so that the gas above the movable disc 3 in the first cavity 14 will pass through the one-way hole 62 on the spherical shell 6 in the first cavity 14 under the double actions of the negative pressure and the pressure of the gas itself, and as the rotating shaft 5 continues to drive the movable disc 3 in the first cavity 14 to rotate, the movable block 33 in the first cavity 14 will move downward when the movable block 33 is out of engagement with the fixed block 34, so that the negative pressure is formed above the movable disc 3 in the first cavity 14 while the gas pressure below increases, and the movable disc 3 in the first cavity 14 will move up and down during the rotation of the rotating shaft 5 and move in the gas conveying area 36, so that the gas circulates along the first cavity 14, the side pipe 4, the second cavity 15, the one-way hole 62 on the spherical shell 6 in the second cavity 15, the space between the movable disc 3 and the grinding body 12 in the second cavity 15, the grinding gap 17, the space between the grinding body 12 and the movable disc 3 in the first cavity 14, and the one-way hole 62 on the spherical shell 6 in the first cavity 14; so that the material in the grinding gap 17 can flow in the gas flow during the grinding process, and the grinding efficiency is further improved; the powdered material ground from the grinding gap 17 will fall on the upper surface of the movable disc 3 in the first cavity 14, and as the movable disc 3 also rotates, the material will move away from the one-way hole 62 on the spherical shell 6 in the first cavity 14 under the centrifugal force during the rotation of the movable disc 3 in the first cavity 14, so that the gas can be filtered by the filter screen at the upper end of the one-way hole 62 in the first cavity 14 and then discharged from the lower end of the one-way hole 62 in the first cavity 14.

[0045] After the material in the second cavity 15 is completely ground by the grinding gap 17, loosen the bolt 23, rotate the grinding cylinder 1, so that the grinding cylinder 1 rotates between the two supports 21, and the second cavity 15 is located directly below the first cavity 14, tighten the bolt 23, and the rotating motor 13 continues to drive the grinding body 12 and the two movable discs 3 to rotate, the one-way hole 62 of the spherical shell 6 remains vertical, and changes the direction of the airflow inside the grinding cylinder 1 after the grinding cylinder 1 is turned over, the movable disc 3 in the second cavity 15 cooperates with the fixed block 34, so that the gas flows along the movable disc 3 below the second cavity 15, the side pipe 4, the movable disc 3 above the first cavity 14, the one-way hole 62 on the spherical shell 6 of the first cavity 14, between the movable disc 3 and the grinding body 12 in the first cavity 14, the grinding gap 17, the grinding body 12 and the movable disc 3 above the second cavity 15, and the one-way hole 62 on the spherical shell 6 in the second cavity 15, and then circulates in sequence, the gas flows through the grinding gap 17 with the material, so that the material in the first cavity 14 is ground again and flows into the second cavity 15 through the grinding gap 17; After the second grinding is completed, the grinding cylinder 1 can be continued to be adjusted according to the needs, so that the materials in the first cavity 14 and the second cavity 15 are transferred back and forth and ground, thereby making the tea grinding more sufficient while maintaining high efficiency.

[0046] Third step, discharging stage:

[0047] After the grinding is completed, the motor 13 is stopped to rotate, and the ground material in the second cavity 15 is taken as an example. The bolt 23 is loosened, the grinding cylinder 1 is rotated to drive the material port 18 connected with the second cavity 15 to tilt downward, then the bolt 23 is tightened, the material frame is placed below the material port 18 connected with the second cavity 15, the material door 19 on the material port 18 connected with the second cavity 15 is opened, after the material door 19 is opened, the material in the second cavity 15 flows out along the connected material port 18, the motor 13 drives the rotating shaft 5 to rotate at a low speed, the rotating shaft 5 drives the two movable discs 3 to rotate, the movable disc 3 in the second cavity 15 drives the movable block 33 to contact the fixed block 34, so that the movable disc 3 in the second cavity 15 moves axially in the gas conveying area 36, and the movable disc 3 in the second cavity 15 moves close to the grinding body 12, so that the space below the movable disc 3 in the second cavity 15 becomes larger to form negative pressure, so that the gas between the grinding body 12 and the upper side of the movable disc 3 in the second cavity 15 enters the lower side of the movable disc 3 in the second cavity 15 along the one-way hole 62 on the spherical shell 6 in the second cavity 15, the gas below the movable disc 3 in the second cavity 15 is discharged during the downward movement of the movable disc 3, so that the gas flows in the second cavity 15 in sequence along the lower side of the movable disc 3 in the second cavity 15, the side pipe 4, the upper side of the movable disc 3 in the first cavity 14, the one-way hole 62 on the spherical shell 6 in the first cavity 14, the lower side of the movable disc 3 in the first cavity 14 and the grinding body 12, the grinding gap 17, the upper side of the movable disc 3 in the second cavity 15 and the one-way hole 62 on the spherical shell 6 in the second cavity 15, so that the grinding gap 17 and the residual material in the first cavity 14 are moved to the second cavity 15, and the movable disc 3 rotates during the axial reciprocating movement in the gas conveying area 36, so that the movable disc 3 drives the fixed stirring rod 37 to stir the material in the second cavity 15, and the material discharge and collection process in the grinding cylinder 1 is completed.
