[0018] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in conjunction with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0019] According to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes a device for eliminating blockage at the coal bunker opening, including a base 1, a column 2, a sliding sleeve 3, and a rocker arm 4. The top of the base 1 is fixedly connected to the column 2. The outside of the column 2 is slidably connected to the sliding sleeve 3. The outside of the sliding sleeve 3 is fixedly connected to the rocker arm 4. One end of the rocker arm 4 is provided with a drive box 6. A crushing mechanism is provided on the drive box 6. A locking mechanism is provided inside the sliding sleeve 3. A lifting mechanism is provided at the top of the column 2. A horizontal movement mechanism is provided between the drive box 6 and the rocker arm 4. Install this device at the coal bunker opening. During use, release the restriction of the locking mechanism on the sliding sleeve 3, so that the rocker arm 4 can rotate around the column 2, suspend the crushing mechanism above the coal bunker opening, then the locking mechanism locks the position of the sliding sleeve 3 again, moves it above the crushing area through the horizontal movement mechanism, and the lifting mechanism drives the rocker arm 4 to move downward, so that the crushing mechanism crushes the large pieces of coal, gangue or other sundries blocked below it. At this time, they can slide down along the inner wall of the coal bunker opening, avoiding blockage at the coal bunker opening and consuming less time.

[0020] The locking mechanism includes a hydraulic clamping cylinder 7, a hydraulic pump box 8, and a hydraulic pipe 9. The outside of the rocker arm 4 is fixedly connected to the hydraulic pump box 8. The hydraulic clamping cylinder 7 is provided inside the sliding sleeve 3. The hydraulic pump box 8 and the hydraulic clamping cylinder 7 are interconnected through the hydraulic pipe 9. A control valve and a hydraulic pump are also installed inside the hydraulic pump box 8. When it is necessary to clamp the workpiece, open the control valve, and the hydraulic pump makes the hydraulic oil flow to the sliding sleeve 3, pushing the hydraulic clamping cylinder 7 to move upward, and squeezing the hydraulic clamping cylinder 7 to contract inward through the conical groove at the top of the sliding sleeve 3 to clamp the column 2. Then close the control valve to cut off the liquid flow to maintain the state of clamping the workpiece. When it is necessary to release the clamped workpiece, open the control valve again to make the hydraulic oil flow back to the hydraulic pump box 8, no longer push the hydraulic clamping cylinder 7 to move upward, and the hydraulic clamping cylinder 7 and the conical groove are separated from each other, thereby realizing the contraction of the hydraulic clamping cylinder 7 and the release of the clamping mechanism, so as to adjust the drive box 6 to be above the coal bunker opening.

[0021] The crushing mechanism includes a driving motor 10 and a drill bit 11. The driving motor 10 is fixedly installed on the top of the driving box 6. The bottom end of the driving box 6 is rotatably connected to the drill bit 11. The output end of the driving motor 10 is fixedly connected to the top end of the drill bit 11. The driving motor 10 can drive the drill bit 11 to rotate at the bottom of the driving box 6. When the swing arm 4 moves downward, the drill bit 11 also moves downward following the swing arm 4, playing an impact role on large pieces of coal, gangue or other sundries to crush them.

[0022] The horizontal movement mechanism includes a rack 16, a rotating motor 17 and a second gear 18. The rack 16 is fixedly connected to the top of the swing arm 4. The rotating motor 17 is fixedly installed on the back side of the driving box 6. The output end of the rotating motor 17 is fixedly connected to the second gear 18. The second gear 18 meshes with the rack 16. The rotating motor 17 drives the second gear 18 to rotate on the top of the driving box 6. The second gear 18 meshes with the rack 16, which can convert the rotational movement of the second gear 18 into the linear movement of the driving box 6. And the forward and reverse rotation of the rotating motor 17 controls the moving direction of the driving box 6 to drive the driving box 6 to reciprocate horizontally on the swing arm 4 and adjust the driving box 6 to be above the blocked position.

[0023] One side of the driving box 6 is threadedly connected with a threaded rod 19. One end of the threaded rod 19 is rotatably connected to a limiting plate 20. One end of the limiting plate 20 penetrates between two meshing teeth on the rack 16. After adjusting the position of the driving box 6, rotating the threaded rod 19 forward drives the limiting plate 20 to move towards the rack 16 until the limiting plate 20 is inserted between two meshing teeth to limit the driving box 6. When the driving box 6 needs to move, rotating the threaded rod 19 in the reverse direction drives the limiting plate 20 to withdraw from between two meshing teeth.

[0024] The lifting mechanism includes a housing 12, a lifting motor 13, a first gear 14, and a lead screw 15. The top of the column 2 is fixedly connected to the housing 12. The top of the housing 12 is fixedly installed with the lifting motor 13. One side of the bottom of the housing 12 is rotatably connected to the lead screw 15. The top ends of the lead screw 15 and the output end of the lifting motor 13 are both fixedly connected to the first gear 14. The bottom end of the lead screw 15 penetrates through one end of the rocker arm 4 and is threadedly connected thereto. The outer walls of the two first gears 14 mesh with each other. The interior of the housing 12 encloses the two first gears 14. The lifting motor 13 drives the first gear 14 at its output end to rotate. The two first gears 14 mesh with each other, and the lead screw 15 is also fixed together with another first gear 14. Therefore, the lifting motor 13 can drive the lead screw 15 to rotate. The lead screw 15 is in threaded cooperation with the rocker arm 4, and the sliding sleeve 3 and the column 2 cooperate to limit the rocker arm 4, so that when the lead screw 15 rotates forward and backward, it can drive the rocker arm 4 to move up and down reciprocally, so as to drive the drill bit 11 to move downward to break the blockage and move upward to reset.

[0025] For the device for eliminating the blockage at the coal bunker opening, install this device at the coal bunker opening. When in use, release the restriction of the locking mechanism on the sliding sleeve 3, so that the rocker arm 4 can rotate around the column 2, suspend the crushing mechanism above the coal bunker opening, and then the locking mechanism locks the position of the sliding sleeve 3 again. Move it above the crushing area through the horizontal movement mechanism. The lifting mechanism drives the rocker arm 4 to move downward, so that the crushing mechanism crushes the large pieces of coal, gangue or other sundries blocked below it. At this time, they can slide downward along the inner wall of the coal bunker opening, avoiding blockage at the coal bunker opening and consuming less time.
