Description

Technical Field

[0001] This invention relates to the field of coal bunker cleaning equipment technology, and in particular to a mechanical device and method for cleaning shrimp-shaped coal bunkers. Background Technology

[0002] Existing coal bunkers are mostly shrimp-shaped bunkers with large volumes, featuring an inlet and skylight at the top, and a conical outlet at the bottom. However, during use, due to the irregular shape of the solid powder and lumps inside the bunker, coupled with the small size of the outlet, the following types of blockages often occur:

[0003] 1. Bridging: When particulate material forms an arched structure inside the coal bunker, the material no longer flows freely.

[0004] 2. Rat hole: The granular material forms a central channel or hole inside the coal bunker, while the surrounding material is squeezed or stuck together, causing the material to not flow evenly.

[0005] 3. Adhesion to the wall: Particles stick to the inner wall of the coal bunker, preventing the material from sliding down smoothly.

[0006] These phenomena prevent solid powder and lumps from flowing out smoothly, affecting normal material handling processes. When solid powder and lumps in the coal bunker cause blockages due to bridging, rodent holes, or adhesion to the walls, it is necessary to unclog the coal bunker. Existing unblocking methods include:

[0007] 1. Install a built-in mechanical dredging machine: It is usually used to solve the blockage of coal bunker caused by bridging, but it is not effective for blockages caused by rat holes or hanging on the wall.

[0008] 2. Install air cannons and vibratory devices on the warehouse walls: These are usually used to solve blockages caused by rat holes or hanging on the walls, but their effect on blockages caused by bridging is limited.

[0009] Therefore, there is currently no comprehensive coal bunker cleaning system capable of resolving all types of blockages, necessitating the use of multiple devices to address different blockage issues. Using multiple devices increases procurement costs, requiring not only the purchase of different equipment but also additional installation and maintenance expenses. The operating and maintenance costs of multiple devices are also relatively high, increasing the operational burden on enterprises. Furthermore, in practice, switching between different devices to address different blockage problems increases operational complexity and workload, and the presence of multiple devices makes maintenance work more complex and difficult. Summary of the Invention

[0010] The purpose of this invention is to provide a mechanical device for cleaning shrimp-shaped coal bunkers that can comprehensively solve various blockage phenomena in order to address the aforementioned problems.

[0011] The present invention achieves the above-mentioned objective through the following technical solution: a mechanical device for cleaning shrimp-shaped coal bunkers, comprising a servo motor, an electric slide rail connected to the output shaft of the servo motor, a mounting plate connected to the slider of the electric slide rail, an electric winding wheel I mounted on the mounting plate, a pull rope I wound on the electric winding wheel I, a connecting column connected to the pull rope I, a connecting frame rotatably connected to the bottom of the connecting column, a connecting block capable of vertical rotation provided at the lower part of the connecting frame, a detachable vibrating chisel mounted at the bottom of the connecting block, a clearing plate capable of vertical rotation evenly spaced along the circumference at the lower part of the vibrating chisel, two fixed pulleys on the upper part of one side of the connecting frame, an electric winding wheel II mounted on the mounting plate, a pull rope II wound on the electric winding wheel II, the pull rope II passing through the connecting column and around the fixed pulleys to connect with the vibrating chisel.

The lower part of the hollow sleeve is connected with wedge blocks evenly spaced along the circumference. The wedge blocks are located on the upper side of the grooves and correspond one-to-one with the drain plate. The wedge blocks and their corresponding drain plates are in contact to push the drain plate to rotate downward. A telescopic sleeve is connected to the outer wall of the hollow sleeve. The telescopic sleeve is connected to the bottom of the mounting cylinder to seal the gap between the hollow sleeve and the mounting cylinder. A rod frame is connected to the top of the hollow sleeve. The rod frame extends into the mounting cylinder and slides with the mounting cylinder. A spring II is connected between the rod frame and the mounting cylinder.

[0014] Preferably, the upper part of the chisel head is connected to a rubber sleeve for sealing its upper receiving opening, and the drain plate extends out of the rubber sleeve.

[0015] Preferably, the connecting column is provided with a rotation adjustment mechanism, which includes a connecting plate connected to the outer wall of the connecting column. Two electric winding wheels III are symmetrically connected to the mounting plate. Each of the two electric winding wheels III is wound with a pull rope III. Both pull ropes III pass through the connecting plate and are connected to the connecting frame to pull the connecting frame to rotate alternately in both directions around the connecting column as the rotation center.

[0016] Preferably, the outer wall of the mounting cylinder is provided with a detection mechanism, which includes a detachable cover connected to the outer wall of the mounting cylinder. The cover is cone-shaped, wider at the bottom and narrower at the top. A transparent sealing plate for sealing the cover is connected to the lower inner part of the cover. An annular plate is connected inside the cover. The annular plate is slidably fitted onto the outside of the mounting cylinder. Lighting lamps are evenly spaced along the circumference at the bottom of the annular plate. Cameras are evenly spaced along the circumference at the bottom of the annular plate. Each camera is located between two adjacent lighting lamps.

[0017] Preferably, the outer wall of the mounting cylinder is provided with a cleaning mechanism for cleaning the cover and the transparent sealing plate. The cleaning mechanism includes a detachable drive motor installed on the outer wall of the mounting cylinder. A gear set is provided between the output shaft of the drive motor and the cover.

The inclined section of the scraper is in close contact with the outer wall of the conical cover, and the horizontal section of the scraper is in close contact with the bottom of the transparent sealing plate.

[0018] Preferably, the top of the mounting cylinder, the connecting frame, and the connecting column are all provided with wire holes for guiding the power cord of the vibration motor, and the connecting frame is provided with a silicone sleeve for securing and limiting the power cord of the vibration motor.

[0019] A method for using a mechanical device for cleaning shrimp-shaped coal bunkers, based on the mechanical device for cleaning shrimp-shaped coal bunkers as described in claim 5, is characterized by comprising the following steps:

[0020] S1. Installation: Install the servo motor in the middle of the top inside the shrimp-shaped coal bunker.

[0021] S2. To clear blockages caused by rat holes or wall adhesion, control the electric winding wheel I to release and retract the pull rope I, causing the vibrating chisel to move downwards and upwards. Simultaneously, control the vibrating motor to drive the connecting rod, causing the chisel head to vibrate up and down. The downward movement and repeated up-and-down vibration of the chisel head can pierce the material, clearing the blockage. Control the electric winding wheel II to retract the pull rope II, pulling the entire vibrating chisel upwards to an inclined or horizontal position. The upward rotation and repeated vibration of the chisel head can better clean materials close to or adhering to the inner wall of the coal bunker. The system controls two electric winding wheels Ⅲ to alternately release and rewind the pull rope Ⅲ on them, thereby pulling the connecting frame through the connecting block to drive the entire vibratory chisel to rotate alternately in both directions around the connecting column as the rotation center, increasing the cleaning area. By releasing and rewinding the pull rope Ⅰ through the electric winding wheel Ⅰ, the vibratory chisel can clear rat holes or blockages caused by hanging on the wall from top to bottom. The electric slide rail can drive the vibratory chisel to move radially along the coal bunker to clear rat holes or blockages caused by hanging on the wall. The servo motor can drive the electric slide rail to rotate, thereby driving the vibratory chisel to rotate circumferentially along the coal bunker to clear rat holes or blockages caused by hanging on the wall.

[0022] S3. To clear blockages caused by bridging, manually rotate the bolts on the connecting block to disengage them from the mounting cylinder, thus detaching the mounting cylinder from the connecting block. Then, control the electric winding wheel II to release the pull rope II. Under the action of gravity, the vibrating chisel moves the clearing plate down to below the material. Subsequently, control the electric winding wheel II to rewind the pull rope II, thereby pulling the vibrating chisel to move the clearing plate up. The upward movement of the clearing plate pushes the material upward, thus clearing the blockage caused by bridging.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The electric winding wheel II can pull the vibratory chisel upwards to a tilted or horizontal position by winding the rope II. After the chisel head on the vibratory chisel rotates upwards to a tilted or horizontal position, it vibrates repeatedly, which can better clean the material close to or adhering to the inner wall of the coal bunker, and unclog blockages caused by rat holes or wall adhesion. The vibratory chisel drives the unblocking plate to move the material upwards, which can unclog blockages caused by bridging. Thus, the invention can unclog blockages caused by rat holes, wall adhesion, and bridging, and achieve the effect of comprehensively solving various blockages. It solves the problem of having to switch between multiple devices to deal with different blockages in the existing technology, reduces costs, reduces the operating burden of enterprises, reduces the complexity and workload of operation, and reduces the complexity and difficulty of maintenance.

[0025] 2. Through the cooperation of the electric winding wheel III and the pull rope III, the vibratory chisel can be driven to rotate alternately in both directions around the connecting column, thereby increasing the cleaning area and improving the cleaning effect and efficiency.

[0026] 3. The lighting can provide illumination, and the camera can monitor the cleaning of rat holes or wall blockages, so that staff can keep track of the cleaning progress. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] Example 1

[0038] A mechanical device for cleaning shrimp-shaped coal bunkers, see [link / reference] Figures 1-2The system includes a servo motor 1, an electric slide rail 2 connected to the output shaft of the servo motor 1, a mounting plate 3 connected to the slider of the electric slide rail 2, an electric winding wheel I 4 mounted on the left side of the mounting plate 3, a pull rope I 5 wound on the electric winding wheel I 4, a connecting post 6 connected to the pull rope I 5, and a connecting frame 7 rotatably connected to the bottom of the connecting post 6 via a rotating shaft. The connecting frame 7 includes an inverted U-shaped plate and a V-shaped plate. The inverted U-shaped plate is rotatably connected to the bottom of the connecting post 6 via a rotating shaft, and the V-shaped plate is connected to the inner top of the inverted U-shaped plate. The lower part of the V-shaped plate on the connecting frame 7 is rotatably connected to a connecting block 8 via a rotating shaft. The connecting block 8 is U-shaped, and a detachable vibratory chisel 9 is installed at the bottom of the U-shaped connecting block 8. The vibratory chisel 9 includes a mounting cylinder 91 bolted to the bottom of the U-shaped connecting block 8. Four guide rods 92 are evenly spaced along the circumferential direction on the inner bottom of the mounting cylinder 91. A connecting plate 93 is slidably connected between the four guide rods 92. A spring I 94 is sleeved on the guide rods 92, and the two ends of the spring I 94 are respectively connected to the connecting plate. The bottom of plate 93 is connected to the inner bottom of mounting cylinder 91. A vibrating motor 95 is mounted on the bottom of plate 93, and a connecting rod 96 is connected to the vibrating motor 95. The bottom of the connecting rod 96 passes through the bottom of mounting cylinder 91 and is connected to a chisel 97. The upper part of the chisel 97 is circular, and the lower part is a flat conical shape with a sharp bottom, which makes it easier to insert into the material. Three receiving ports 98 are evenly opened circumferentially on the circular side wall of the chisel 97. Each of the three receiving ports 98 is hinged to a device that can rotate up and down. The unblocking plate 10 has three evenly spaced receiving slots 99 on the lower part of the connecting rod 96 to accommodate the unblocking plate 10. The upper front part of the V-shaped plate on the connecting frame 7 is rotatably connected to two fixed pulleys 11. An electric winding wheel II 12 is installed on the left side of the mounting plate 3. The electric winding wheel II 12 is located below the electric winding wheel I 4. A pull rope II 13 is wound on the electric winding wheel II 12. The pull rope II 13 first passes through the connecting column 6, then passes between the two fixed pulleys 11, and finally connects to the mounting cylinder 91.

[0039] The servo motor 1 is installed in the middle of the top inner side of the shrimp-shaped coal bunker. When the coal bunker is blocked and the material cannot be discharged smoothly, the staff holds an imaging scanner and places it into the coal bunker through the skylight above the coal bunker to check the blockage. If the blockage at the bottom of the coal bunker is a rat hole (the granular material forms a central channel or hole inside the coal bunker, while the surrounding material is squeezed or stuck together, causing the material to not flow evenly) or a wall-hanging (the granular material adheres to the inner wall of the coal bunker, causing the material to not slide down smoothly), first control the servo motor 1 to drive the electric slide rail 2 to rotate above the material, and then control the electric slide rail 2 to drive the mounting plate 3 to move its upper parts to directly above the material, so that the vibrating chisel 9 and the unblocking plate 10 move directly above the material. Then, control the electric winding wheel I4 to rotate and release the pull rope I5. Under the action of gravity, the vibrating chisel 9 moves down. At the same time, control the vibrating motor 95 to work so that the connecting rod 96 drives the chisel head 97 to vibrate up and down. The chisel head 97 moves down and vibrates up and down repeatedly to chisel and puncture the material, so as to clear the material and achieve the cleaning of the warehouse. After cleaning materials far from the inner wall of the coal bunker, when it is necessary to clean materials close to or adhering to the inner wall, the electric winding wheel II12 can be controlled to rotate and rewind the pull rope II13, thereby pulling the entire vibrating chisel 9 upward to an inclined or horizontal position. After the chisel head 97 rotates upward to an inclined or horizontal position, repeated vibration can better clean materials close to or adhering to the inner wall of the coal bunker. By releasing and rewinding the pull rope I5 through the electric winding wheel I4, the vibrating chisel 9 can be made to unclog rat holes or blockages caused by wall adhesion from top to bottom. The electric slide rail 2 can drive the vibrating chisel 9 to move radially along the coal bunker to unclog rat holes or blockages caused by wall adhesion. The servo motor 1 can drive the electric slide rail 2 to rotate, thereby driving the vibrating chisel 9 to rotate circumferentially along the coal bunker to unclog rat holes or blockages caused by wall adhesion, thus achieving a complete cleaning of the bunker.

[0040] If the blockage at the bottom of the coal bunker is due to bridging (the granular material forms an arched structure inside the bunker, preventing free flow), first, control the electric winding wheel II12 to reverse and release the pull rope II13. Under gravity, the vibrating chisel 9 will rotate downwards back to a vertical position. Then, manually rotate the bolt on the connecting block 8 to disengage it from the mounting cylinder 91, thus detaching the mounting cylinder 91 from the connecting block 8. Next, control the electric winding wheel II12 to reverse and release the pull rope II13. Under gravity, the vibrating chisel 9 will move downwards, while the connecting column 6 will be held back by the pull rope I5, preventing it from moving downwards. This holds the connecting frame 7 and the connecting block 8 in place, preventing them from being jammed by the material and thus avoiding obstruction of the subsequent up-and-down movement of the vibrating chisel 9. The vibrating motor 95 enables the chisel head 97 to vibrate repeatedly up and down during downward movement, ensuring that the chisel head 97 smoothly passes through the material and moves below it. The chisel head 97 moves downward, causing the unblocking plate 10 to move downward as well. As the unblocking plate 10 moves downward, it is pushed upward by the material and rotates into the receiving groove 99, thereby reducing the contact area between the unblocking plate 10 and the material. This allows the unblocking plate 10 to move smoothly downward with the chisel head 97 to below the material. After the unblocking plate 10 moves downward to below the material, it rotates downward to reset under the action of gravity. Then, the electric winding wheel II 12 is controlled to rotate and wind up the pull rope II 13, which pulls the vibrating chisel 9 to move the unblocking plate 10 upward. After the unblocking plate 10 moves upward and contacts the material at the lowest end, it is pushed downward to rotate to a horizontal state by the material at the lowest end. Subsequently, the unblocking plate 10 continues to move upward, pushing the material upward, thereby clearing the arched material and unblocking the blockage caused by bridging. This device can clear blockages caused by rat holes, wall hangings, and bridging, achieving a comprehensive solution to various blockage phenomena. It solves the problem of having to switch between multiple devices to deal with different blockages in existing technologies, reducing costs, decreasing the operational burden on enterprises, reducing operational complexity and workload, and lowering maintenance complexity and difficulty.

[0041] See Figures 3-4The connecting rod 96 is equipped with a sealing mechanism for sealing the receiving groove 99. The sealing mechanism includes a hollow sleeve rod 141 that slides on the connecting rod 96. The lower part of the hollow sleeve rod 141 has three grooves 144 evenly spaced along the circumference to accommodate the drain plates 10. The lower part of the hollow sleeve rod 141 is connected to three wedge blocks 142 evenly spaced along the circumference. The wedge blocks 142 are located on the upper side of the grooves 144. The three wedge blocks 142 contact the three drain plates 10 respectively to push the drain plates 10 to rotate downward. A telescopic sleeve 143 is connected to the outer wall of the hollow sleeve rod 141. The telescopic sleeve 143 is connected to the bottom of the mounting cylinder 91 to seal the gap between the hollow sleeve rod 141 and the mounting cylinder 91, preventing material from entering the gap between the hollow sleeve rod 141 and the mounting cylinder 91 and jamming the hollow sleeve rod 141. This ensures that the hollow sleeve rod 141 can move smoothly up and down. A rod frame 145 is connected to the top of the hollow sleeve rod 141. The rod frame 145 extends into the mounting cylinder 91 and slides with the mounting cylinder 91. The rod frame 145 consists of two upper and lower round blocks and two sliding rods. The lower round block is connected to the top of the hollow sleeve rod 141, and the upper round block is slidably connected to the upper inner part of the mounting cylinder 91. The upper round block is located above the connecting plate 93. The two sliding rods are connected between the two round blocks and are slidably connected to the mounting cylinder 91. A spring II 146 is connected between the top of the upper round block on the rod frame 145 and the top inner side of the mounting cylinder 91. A rubber sleeve 15 for sealing the upper receiving port 98 is connected to the circular side wall of the chisel head 97. The unblocking plate 10 extends out of the rubber sleeve 15. By sealing the receiving port 98 on the chisel head 97 with the rubber sleeve 15, it is possible to prevent material from entering the receiving port 98 and jamming the unblocking plate 10, thereby ensuring that the unblocking plate 10 rotates smoothly up and down.

[0042] The hollow sleeve rod 141 seals the receiving groove 99 to prevent material from entering and jamming the unblocking plate 10, thus ensuring the smooth upward rotation of the unblocking plate 10 into the receiving groove 99. When the unblocking plate 10 rotates upward, it pushes the wedge block 142, causing the hollow sleeve rod 141 to move upward. The rod frame 145 moves upward, compressing the spring II 146. When the unblocking plate 10 moves downward below the material, the spring II 146 resets, pushing the rod frame 145, causing the hollow sleeve rod 141 to move downward. The wedge block 142 moves downward, pushing the unblocking plate 10 to rotate downward. This assists the unblocking plate 10 in rotating downward, preventing it from remaining in the receiving groove 99 and causing blockage due to bridging.

[0043] See Figure 1 and Figure 5The connecting column 6 is equipped with a rotation adjustment mechanism, which includes a connecting plate 161 connected to the outer wall of the connecting column 6. The connecting plate 161 is I-shaped. Two electric winding wheels Ⅲ163 are symmetrically connected to the mounting plate 3. Each of the two electric winding wheels Ⅲ163 is wound with a pull rope Ⅲ162. Both pull ropes Ⅲ162 pass through the connecting plate 161. The pull rope Ⅲ162 on the front electric winding wheel Ⅲ163 is connected to the left rear side of the V-shaped plate on the connecting frame 7, and the pull rope Ⅲ162 on the rear electric winding wheel Ⅲ163 is connected to the right front side of the V-shaped plate on the connecting frame 7.

[0044] When the vibratory chisel 9 rotates upward to an inclined or horizontal position to clean materials close to or adhering to the inner wall of the coal bunker, the front electric winding wheel Ⅲ163 is controlled to wind up the pull rope Ⅲ162 on it, and the rear electric winding wheel Ⅲ163 is controlled to release the pull rope Ⅲ162 on it. This pulls the connecting frame 7 to rotate around the connecting column 6. Then, the front electric winding wheel Ⅲ163 is controlled to release the pull rope Ⅲ162 on it, and the rear electric winding wheel Ⅲ163 is controlled to wind up the pull rope Ⅲ162 on it. This pulls the connecting frame 7 to rotate in reverse around the connecting column 6. The connecting frame 7 rotates alternately in both directions around the connecting column 6. Through the connecting block 8, the entire vibratory chisel 9 rotates alternately in both directions around the connecting column 6. The alternating rotation of the chisel head 97 can increase the cleaning area, thereby improving the cleaning effect and efficiency.

[0045] See Figures 6-7 The outer wall of the mounting cylinder 91 is provided with a detection mechanism, which includes a cover 171 bolted to the outer wall of the mounting cylinder 91. The cover 171 is conical in shape, wider at the bottom and narrower at the top. A transparent sealing plate 172 for sealing the cover 171 is connected to the lower inner part of the cover 171. An annular plate 173 is connected inside the cover 171. The annular plate 173 is slidably fitted onto the outside of the mounting cylinder 91. Four lighting lamps 174 are evenly spaced along the circumference at the bottom of the annular plate 173. Two cameras 175 are evenly spaced along the circumference at the bottom of the annular plate 173. Each camera 175 is located between two adjacent lighting lamps 174.

[0046] See Figures 6-7The outer wall of the mounting cylinder 91 is provided with a cleaning mechanism for cleaning the cover 171 and the transparent sealing plate 172. The cleaning mechanism includes a drive motor 181 that is bolted to the outer wall of the mounting cylinder 91. A gear set 182 is provided between the output shaft of the drive motor 181 and the cover 171. The gear set 182 consists of a small gear and a large gear. The small gear is connected to the output shaft of the drive motor 181, and the large gear is rotatably connected to the upper part of the outer wall of the cover 171. The small gear and the large gear mesh. A scraper 183 is connected to the bottom of the large gear. The scraper 183 consists of an inclined section and a horizontal section. The inclined section of the scraper 183 is in close contact with the conical outer wall of the cover 171, and the horizontal section of the scraper 183 is in close contact with the bottom of the transparent sealing plate 172.

[0047] The vibratory chisel 9 rotates upwards to either an inclined or horizontal position, causing the cover 171 to rotate upwards to either an inclined or horizontal position. This allows the lighting lamp 174 and camera 175 to be aimed at the material adhering to the inner wall of the coal bunker. The lighting lamp 174 provides illumination, and the camera 175 monitors the cleaning progress of rat holes or wall blockages, enabling workers to monitor the cleaning process. During cleaning, material may fall onto the cover 171 and the transparent sealing plate 172, affecting the camera 175's monitoring. Controlling the drive motor 181 causes the gear set 182 to rotate the scraper 183. The rotating scraper 183 cleans the material remaining on the cover 171 and the transparent sealing plate 172, preventing material from obstructing the camera 175's monitoring. To clear the blockage caused by bridging, manually turn the bolts on the drive motor 181 and the cover 171 to remove the drive motor 181 and the cover 171 from the mounting cylinder 91. This prevents the drive motor 181 and the gear set 182 from entering the material along with the mounting cylinder 91, thus preventing the gear set 182 from being jammed by the material. When it is necessary to use the camera 175 for monitoring again, simply reinstall the drive motor 181 and the cover 171 back onto the mounting cylinder 91 using the bolts.

[0048] See Figure 8 The top of the mounting cylinder 91, the inverted U-shaped plate of the connecting frame 7, and the connecting column 6 are all provided with wire holes 20. The wire holes 20 are used to guide the power cord of the vibration motor 95. The bottom left side of the inverted U-shaped plate of the connecting frame 7 is connected to a silicone sleeve 19 for tightening and limiting the power cord of the vibration motor 95. Through the cooperation of the silicone sleeve 19 and the wire holes 20, the power cord of the vibration motor 95 can be effectively tightened and limited to prevent the power cord of the vibration motor 95 from being scattered randomly, thereby ensuring the safety and stability of the power cord.

[0049] A method for using a mechanical device for cleaning shrimp-shaped coal bunkers includes the following steps:

[0050] S1. Installation: Install the servo motor 1 in the middle of the top inside the shrimp-shaped coal bunker.

[0051] S2. To clear blockages caused by rat holes or wall adhesion, control the electric winding wheel I4 to release and rewind the pull rope I5, causing the vibrating chisel 9 to move downwards and upwards. Simultaneously, control the vibrating motor 95 to drive the connecting rod 96 to vibrate the chisel head 97 up and down. The downward movement and repeated up-and-down vibration of the chisel head 97 can pierce the material to clear blockages. Control the electric winding wheel II12 to rewind the pull rope II13, pulling the entire vibrating chisel 9 upwards to an inclined or horizontal position. The upward rotation and repeated vibration of the chisel head 97 can better clean materials close to or adhering to the inner wall of the coal bunker. The system controls two electric winding wheels Ⅲ163 to alternately release and rewind the pull rope Ⅲ162 on them, so as to pull the connecting frame 7 through the connecting block 8 to drive the entire vibrating chisel 9 to rotate alternately in both directions around the connecting column 6 as the rotation center, thereby increasing the cleaning area. The electric winding wheel Ⅰ4 releases and rewinds the pull rope Ⅰ5, which enables the vibrating chisel 9 to clear rat holes or blockages caused by hanging on the wall from top to bottom. The electric slide rail 2 can drive the vibrating chisel 9 to move radially along the coal bunker to clear rat holes or blockages caused by hanging on the wall. The servo motor 1 can drive the electric slide rail 2 to rotate, thereby driving the vibrating chisel 9 to rotate circumferentially along the coal bunker to clear rat holes or blockages caused by hanging on the wall.

[0052] S3. To clear the blockage caused by bridging, manually rotate the bolt on the connecting block 8 to disengage it from the mounting cylinder 91, thus detaching the mounting cylinder 91 from the connecting block 8.
