The movable sealing plate 5 is arranged on one side of the rotating rod 6. The movement groove 7 is arranged on the inner side surface of the base 3. Both sides of the movable sealing plate 5 can extend into the movement groove 7 and are rotatably sealed in cooperation. One end of the hydraulic rod 4 is movably connected to the bottom of the movable sealing plate 5 in cooperation. The gear lubrication mechanism includes a lubricating gear 8, a fixing plate 9, an oil storage cavity 10, a support spring 11 and a movable block 12. The oil storage cavity 10 is arranged inside the lubricating gear. The fixing plate 9 is fixedly installed on the lubricating gear. The support spring 11 is installed on the top end face of the fixing plate 9. The movable block 12 movably penetrates through the tooth grooves of the lubricating gear 8, and the other end of the support spring 11 is connected to the movable block 12 in cooperation. The teeth of adjacent lubricating gears 8 mesh and extend into the tooth grooves to press the reciprocating movable block 12 into the cavity, and the lubricating oil in the cavity is taken out.

[0028] In this embodiment, in the initial state, the movable sealing plate 5 is in the closed position, the rotating rod 6 is stationary, and the hydraulic rod 4 is not activated. When it is necessary to discharge the crushed material, the hydraulic rod 4 is activated to push the movable sealing plate 5 to rotate, so that it cooperates with the movement groove 7 to open the flow port at the bottom. The crushed material is discharged through the flow port at the bottom. The hydraulic rod 4 is activated in the reverse direction, the movable sealing plate 5 rotates back to the closed position, the rotating rod 6 returns to the stationary state, and the bottom flow port is closed.

One end of the lubricating oil pipe 13 is fixedly installed on the side of the lubricating gear 8. Both ends of the linkage rod 16 are respectively connected to the pressing plate 14 and the limiting block 18. The pressing plate 14 is movably arranged at the top end of the lubricating oil pipe 13.

[0030] In this embodiment, the pressing plate 14 is located at the top end of the lubricating oil pipe 13, the linkage rod 16 is in a stationary state, and the return spring 17 is not activated. When the pressing plate 14 is pressed, the linkage rod 16 is pushed to compress the return spring 17, causing the pressing plate 14 to move downward. When the lubricating oil pressure decreases, the return spring 17 pushes the pressing plate 14 to move upward. The concave-convex groove 24 and the concave-convex block 23 cooperate for one-way sealing to prevent the lubricating oil from being discharged. When the lubricating oil pressure returns to normal, the linkage rod 16 and the pressing plate 14 return to the initial position, and the sealing mechanism is ready for the next activation.

The driven shaft 28 is movably penetrated through the crushing box 2, and the lubricating gears 8 are installed on the high-speed shaft 1 and the driven shaft 28, and adjacent lubricating gears 8 are meshed and connected. Crushing blades 21 are installed on the high-speed shaft 1 and the driven shaft 28. Matching blades 22 are connected to the inner wall of the crushing box 2. The crushing blades 21 and the matching blades 22 are arranged to cooperate for crushing. A convex-concave block 23 is installed at the top end inside the lubricating oil pipe 13. An uneven groove 24 is formed on the top end face of the pressing plate 14, and the convex-concave block 23 can be embedded into the uneven groove 24 to cooperate for one-way sealing. A penetrating pipe 25 is connected to the bottom of the lubricating oil pipe 13, and one end of the penetrating pipe 25 penetrates through and extends into the side of the lubricating gear 8, and the limiting block 18 can extend into the penetrating pipe 25 to prevent excessive intake of lubricating oil. Legs 26 are installed at the four surrounding positions of the base 3. A feeding hopper 27 is connected to the top end face of the crushing box 2.

[0032] More specifically, the operator adds the material to be crushed into the feeding hopper 27. The crushing blades 21 on the high-speed shaft 1 and the driven shaft 28 rotate and cooperate with the matching blades 22 on the inner wall of the crushing box 2 to crush the material. During the crushing process, the gear lubrication mechanism automatically provides lubricating oil for the gears to ensure their normal operation. The crushed material is discharged through the bottom circulation mechanism, and the one-way sealing mechanism prevents the leakage of lubricating oil and facilitates the addition of oil. The operator continuously adds new material into the feeding hopper 27 as needed, and the device continuously crushes and discharges the material. The crushing device is maintained and cleaned regularly to ensure its long-term stable operation.

[0033] In summary, when the overall equipment is in use or operation: when the bottom circulation mechanism needs to operate, in the initial state, the movable sealing plate 5 is in the closed position, the rotating rod 6 is stationary, and the hydraulic rod 4 is not activated. When it is necessary to discharge the crushed material, the hydraulic rod 4 is activated to push the movable sealing plate 5 to rotate, so that it cooperates with the movement groove 7 to open the bottom circulation port, and the crushed material is discharged through the bottom circulation port. The hydraulic rod 4 is activated in the reverse direction, the movable sealing plate 5 rotates back to the closed position, the rotating rod 6 returns to the stationary state, and the bottom circulation port is closed. By controlling the inclination of the movable sealing plate 5, the discharge flow rate is adjusted.

[0034] When the operation of the gear lubrication mechanism is required, the oil storage cavity 10 is filled with lubricating oil.

When the lubricating gear 8 rotates, the meshing of adjacent gears presses the movable block 12 into the tooth groove, squeezing the lubricating oil in the oil storage cavity 10. When the movable block 12 is pressed in, the lubricating oil is carried out to lubricate the meshing part of the lubricating gear 8. When the gear meshing ends, the support spring 11 pushes the movable block 12 back to the initial position to prepare for the next lubrication cycle.

[0035] When the operation of the one-way sealing mechanism is required, the pressing plate 14 is located at the top of the lubricating pipe 13, the linkage rod 16 is in a static state, and the return spring 17 is not activated. When the pressing plate 14 is pressed, the linkage rod 16 is pushed, compressing the return spring 17, causing the pressing plate 14 to move downward. When the lubricating oil pressure decreases, the return spring 17 pushes the pressing plate 14 upward. The concave-convex groove 24 and the concave-convex block 23 cooperate for one-way sealing to prevent the lubricating oil from discharging. When the lubricating oil pressure returns to normal, the linkage rod 16 and the pressing plate 14 return to the initial position, and the sealing mechanism is ready for the next activation.

[0036] The operator adds the material to be crushed into the adding hopper 27. The crushing blades 21 on the high-speed shaft 1 and the driven shaft 28 rotate and act together with the matching blades 22 on the inner wall of the crushing box 2 to crush the material. During the crushing process, the gear lubrication mechanism automatically provides lubricating oil for the gears to ensure their normal operation. The crushed material is discharged through the bottom flow mechanism. The one-way sealing mechanism prevents the leakage of lubricating oil and facilitates the addition of oil. The operator continuously adds new materials into the adding hopper 27 as needed, and the device continuously crushes and discharges the materials. The crushing device is regularly maintained and cleaned to ensure its long-term stable operation.
