Description

Technical Field

[0001] The present invention relates to the technical field of coal bunker clearing equipment, and in particular to a shrimp-shaped coal bunker clearing mechanical device and a use method thereof. Background Art

[0002] Most existing coal bunkers are shrimp-shaped bunkers with large volumes, with a feed port and skylight on the top and a conical discharge port at the bottom. However, during use, due to the irregular shape of the solid powder blocks in the bunker and the small size of the discharge port, the following blockage phenomena often occur:

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

[0004] 2. Rathole: The granular material forms a central channel or hole inside the coal bunker, and the surrounding materials are squeezed or stuck together, resulting in uneven flow of materials.

[0005] 3. Wall hanging: The granular materials adhere to the inner wall of the coal bunker, which makes the materials unable to slide down smoothly.

[0006] These phenomena prevent the solid powder blocks from flowing out smoothly, affecting the normal material handling process. When the solid powder blocks in the coal bunker are blocked by bridging, rat holes, and wall hanging, the coal bunker needs to be dredged. Existing dredging 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 blockage caused by rat holes or wall hangings.

[0008] 2. Install air cannons and vibration devices on the warehouse wall: usually used to solve blockages caused by rat holes or wall hangings, but the dredging effect is limited for blockages caused by bridging.

[0009] Therefore, there is currently no coal bunker clearing mechanical device that can comprehensively solve various blockage phenomena, resulting in the need to use multiple devices to deal with different blockage problems. The use of multiple devices will increase the acquisition cost, not only the need to purchase different equipment, but also additional installation and maintenance costs. The operation and maintenance costs of multiple devices are also relatively high, increasing the operating burden of the enterprise.

DETAILED DESCRIPTION

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

[0037] Example 1

[0038] A mechanical device for cleaning a shrimp-shaped coal bunker, see Figure 1-Figure 2, including a servo motor 1, an electric slide rail 2 is connected to the output shaft of the servo motor 1, a mounting plate 3 is connected to the slider of the electric slide rail 2, an electric winding wheel Ⅰ4 is installed on the left side of the mounting plate 3, a pull rope Ⅰ5 is wound around the electric winding wheel Ⅰ4, a connecting column 6 is connected to the pull rope Ⅰ5, the bottom of the connecting column 6 is rotatably connected to a connecting frame 7 through 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 column 6 through 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 through a rotating shaft. The shape of the connecting block 8 is U-shaped. A removable vibrating chisel 9 is installed at the bottom of the U-shaped connecting block 8. The vibrating chisel 9 includes a mounting cylinder 91 connected to the bottom of the U-shaped connecting block 8 by bolts. Four guide rods 92 are connected to the inner bottom of the mounting cylinder 91 at uniform intervals along the circumferential direction. A connecting plate 93 is slidably connected between the four guide rods 92. A spring I 94 is sleeved on the guide rod 92. Both ends of the spring I 94 are respectively connected to the connecting plate The bottom of the connecting plate 93 is connected to the inner bottom of the mounting tube 91, a vibration motor 95 is installed at the bottom of the connecting plate 93, a connecting rod 96 is connected to the vibration motor 95, the bottom of the connecting rod 96 passes through the bottom of the mounting tube 91 and is connected to a chisel head 97, the upper part of the chisel head 97 is circular, the lower part is a flat cone, and the bottom is sharp, which can be inserted into the material more easily, and the circular side wall of the chisel head 97 is evenly opened along the circumference with three receiving ports 98, and the three receiving ports 98 are hinged with a hinge that can rotate up and down. The dredging plate 10 has three accommodating grooves 99 for accommodating the dredging plate 10 evenly spaced along the circumferential direction at the lower part of the connecting rod 96. The upper front part of the V-shaped plate on the connecting frame 7 is rotatably connected with two upper and lower 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 on the lower side of the electric winding wheel I 4. A pull rope II 13 is wound around 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 is connected to the mounting cylinder 91.

[0039] The servo motor 1 is installed in the middle of the top of the inner side of the shrimp-shaped coal bunker. When the coal bunker is blocked and the materials cannot be discharged smoothly downward, the staff holds the imaging scanner and puts the imaging scanner into the coal bunker through the skylight above the coal bunker to detect the blockage in the coal bunker. 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, and the surrounding materials are squeezed or bonded together, resulting in uneven flow of materials) or wall hanging (the granular material adheres to the inner wall of the coal bunker, resulting in the material not being able to slide down smoothly), first control the servo motor 1 to drive the electric slide rail 2 to rotate to the top of the material, and then control the electric slide rail 2 to drive the mounting plate 3 to drive the upper components to move to the top of the material, so that the vibration chisel 9 and the dredging plate 10 move to the top of the material. Then the electric winding wheel Ⅰ4 is controlled to rotate to release the pull rope Ⅰ5. Under the action of gravity, the vibrating chisel 9 moves downward. At the same time, the vibration motor 95 is controlled to work so that the connecting rod 96 drives the chisel head 97 to vibrate up and down. The chisel head 97 moves downward and repeatedly vibrates up and down to chisel and poke the material, so as to dredge the material and realize warehouse clearance. When the materials far away from the inner wall of the coal bin are cleaned up, if it is necessary to clean the materials close to or adhering to the inner wall of the coal bin, the electric winding wheel Ⅱ12 can be controlled to rotate the winding rope Ⅱ13, thereby pulling the entire vibration chisel 9 to rotate upward to an inclined or horizontal state. After the chisel head 97 rotates upward to an inclined or horizontal state, repeated vibration can better clean the materials close to or adhering to the inner wall of the coal bin. By releasing and winding the rope Ⅰ5 through the electric winding wheel Ⅰ4, the vibration chisel 9 can be used to dredge rat holes or wall hangings from top to bottom. The electric slide rail 2 can drive the vibration chisel 9 to move radially along the coal bin to dredge rat holes or wall hangings. The servo motor 1 can drive the electric slide rail 2 to rotate, thereby driving the vibration chisel 9 to rotate circumferentially along the coal bin to dredge rat holes or wall hangings, thereby achieving comprehensive bin cleaning.

[0040] If the blockage at the bottom of the coal bunker is a bridge (the granular material forms an arched structure inside the coal bunker, and the material no longer flows freely), first control the electric winding wheel Ⅱ12 to reverse and release the pull rope Ⅱ13. Under the action of gravity, the vibrating chisel 9 then turns downward back to a vertical state. Then manually rotate the bolts on the connecting block 8 so that the bolts on the connecting block 8 are disengaged from the mounting cylinder 91 to release the connection between the mounting cylinder 91 and the connecting block 8. Then control the electric winding wheel Ⅱ12 to reverse and release the pull rope Ⅱ13. Under the action of gravity, the vibrating chisel 9 moves downward, while the connecting column 6 is pulled by the pull rope Ⅰ5 and will not move downward, thereby pulling the connecting frame 7 and the connecting block 8 to prevent the connecting frame 7 and the connecting block 8 from moving downward and being stuck by the material, thereby avoiding hindering the subsequent up and down movement of the vibrating chisel 9. The vibrating motor 95 can make the chisel head 97 vibrate up and down repeatedly when moving downward, thereby ensuring that the chisel head 97 smoothly passes through the material and moves downward to the bottom of the material. The chisel head 97 moves downward, driving the dredging plate 10 downward. When the dredging plate 10 moves downward, it is pushed by the material to turn upward into the receiving groove 99, thereby reducing the contact area between the dredging plate 10 and the material, so that the dredging plate 10 follows the chisel head 97 and moves smoothly downward to the bottom of the material. After the dredging plate 10 moves downward to the bottom of the material, under the action of gravity, the dredging plate 10 rotates downward and resets, and then the electric winding wheel Ⅱ12 is controlled to rotate the winding rope Ⅱ13 to pull the vibrating chisel 9 to drive the dredging plate 10 to move upward. After the dredging plate 10 moves upward and contacts with the material at the lowest end, it is pushed by the material at the lowest end to rotate downward to a horizontal state. Then the dredging plate 10 continues to move upward to push the material upward, thereby realizing the dredging of the arched material to clear the blockage caused by the bridging phenomenon. In this way, the device can clear blockages caused by rat holes, wall hangings and bridging, achieving the effect of comprehensively solving various blockage phenomena, solving the problem of needing to switch multiple devices to deal with different blockages in the prior art, reducing costs, reducing the operating burden of the enterprise, reducing the complexity and workload of operations, and reducing the complexity and difficulty of maintenance.

[0041] See also Figure 3-Figure 4The connecting rod 96 is provided with a sealing mechanism for sealing the accommodating groove 99, and the sealing mechanism includes a hollow sleeve rod 141 which is slidably sleeved on the connecting rod 96, and three grooves 144 for accommodating the dredging plate 10 are evenly spaced along the circumferential direction at the lower part of the hollow sleeve rod 141, and three wedge blocks 142 are evenly spaced along the circumferential direction at the lower part of the hollow sleeve rod 141, and the wedge blocks 142 are located on the upper side of the grooves 144. The three wedge blocks 142 are respectively in contact with the three dredging plates 10 to push the dredging plates 10 to rotate downward, and a telescopic sleeve 143 is connected to the outer wall of the hollow sleeve rod 141, and 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, so as to prevent the material from entering the gap between the hollow sleeve rod 141 and the mounting cylinder 91 and jamming the hollow sleeve rod 141, thereby ensuring the smooth up and down movement of the hollow sleeve rod 141, A rod frame 145 is connected to the top of the hollow sleeve 141, and the rod frame 145 extends into the mounting tube 91 and slides with the mounting tube 91. The rod frame 145 is composed of two upper and lower round blocks and two front and rear sliding rods. The lower round block is connected to the top of the hollow sleeve 141, and the upper round block is slidably connected to the inner upper part of the mounting tube 91. The upper round block is located above the connecting plate 93, and the two sliding rods are connected between the two round blocks and are slidably connected to the mounting tube 91. A spring II 146 is connected between the top of the upper round block on the rod frame 145 and the inner top of the mounting tube 91. A rubber sleeve 15 for sealing the accommodating opening 98 thereon is connected to the circular side wall of the chisel head 97. The dredging plate 10 extends out of the rubber sleeve 15, and the accommodating opening 98 on the chisel head 97 is sealed by the rubber sleeve 15, which can prevent materials from entering the accommodating opening 98 and jamming the dredging plate 10, thereby ensuring smooth up and down rotation of the dredging plate 10.

[0042] The hollow sleeve rod 141 can seal the receiving groove 99 to prevent the material from entering the receiving groove 99 and jamming the dredging plate 10, thereby ensuring that the subsequent dredging plate 10 can smoothly move upward into the receiving groove 99. When the dredging plate 10 rotates upward, the wedge block 142 is pushed to move upward with the hollow sleeve rod 141, and the rod frame 145 moves upward to compress the spring II 146. When the dredging plate 10 moves down to the bottom of the material, under the reset action of the spring II 146, the rod frame 145 can be pushed to move downward with the hollow sleeve rod 141, and the wedge block 142 moves downward to push the dredging plate 10 to rotate downward, so that the dredging plate 10 can be assisted to rotate downward, and the dredging plate 10 can be prevented from staying in the receiving groove 99 and affecting the blockage of the dredging bridge phenomenon.

[0043] See also Figure 1 and Figure 5A rotation adjustment mechanism is provided on the connecting column 6, and the rotation adjustment mechanism includes a connecting plate 161 connected to the outer wall of the connecting column 6, and the connecting plate 161 is in an I-shape. Two electric winding wheels III163 are symmetrically connected to the mounting plate 3 front and back, and pull ropes III162 are wound around the two electric winding wheels III163. The two pull ropes III162 pass through the connecting plate 161, and 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 vibrating chisel 9 rotates upward to an inclined or horizontal state to clean materials close to or adhered to the inner wall of the coal bin, the front electric winding wheel III163 is controlled to reel in the pull rope III162 thereon, and the rear electric winding wheel III163 is controlled to release the pull rope III162 thereon, so as to pull the connecting frame 7 to rotate with the connecting column 6 as the rotation center. Subsequently, the front electric winding wheel III163 is controlled to release the pull rope III162 thereon, and the rear electric winding wheel III163 is controlled to reel in the pull rope III162 thereon, so as to pull the connecting frame 7 to reverse with the connecting column 6 as the rotation center. The connecting frame 7 rotates alternately forward and reverse with the connecting column 6 as the rotation center, and the entire vibrating chisel 9 is driven to rotate alternately forward and reverse with the connecting column 6 as the rotation center through the connecting block 8. The alternating forward and reverse rotation of the chisel head 97 can increase the cleaning area to improve the cleaning effect and efficiency.

[0045] See also Figure 6-Figure 7 A searchlight mechanism is provided on the outer wall of the mounting tube 91, and the searchlight mechanism includes a cover body 171 connected to the outer wall of the mounting tube 91 by bolts. The cover body 171 is in the shape of a cone with a larger bottom and a smaller top. A transparent sealing plate 172 for sealing the cover body 171 is connected to the inner lower part of the cover body 171. An annular plate 173 is connected inside the cover body 171. The annular plate 173 is slidably sleeved on the outside of the mounting tube 91. Four illuminating lamps 174 are connected to the bottom of the annular plate 173 at even intervals along the circumferential direction. Two cameras 175 are installed at the bottom of the annular plate 173 at even intervals along the circumferential direction, and each camera 175 is located between two adjacent illuminating lamps 174.

[0046] See also Figure 6-Figure 7A cleaning mechanism for cleaning the cover body 171 and the transparent sealing plate 172 is provided on the outer wall of the mounting cylinder 91, and the cleaning mechanism includes a driving motor 181 installed on the outer wall of the mounting cylinder 91 by bolts, and a gear set 182 is provided between the output shaft of the driving motor 181 and the cover body 171, and the gear set 182 is composed of a small gear and a large gear, the small gear is connected to the output shaft of the driving motor 181, and the large gear is rotatably connected to the upper part of the outer wall of the cover body 171, the small gear and the large gear are meshed, and a scraper 183 is connected to the bottom of the large gear, and the scraper 183 is composed of an inclined surface section and a horizontal section. The inclined surface section on the scraper 183 is close to the outer wall of the conical cover body 171, and the horizontal section on the scraper 183 is close to the bottom of the transparent sealing plate 172.

[0047] The vibrating chisel 9 rotates upward to an inclined or horizontal state, driving the cover 171 to rotate upward to an inclined or horizontal state, so that the lighting lamp 174 and the camera 175 face the materials adhering to the inner wall of the coal bunker, and the lighting lamp 174 can provide lighting, and the camera 175 can monitor the cleaning of the rat hole or the wall blockage phenomenon, so that the staff can grasp the cleaning of the rat hole or the wall blockage phenomenon. When cleaning the materials, the materials may fall on the cover 171 and the transparent sealing plate 172, affecting the monitoring and filming of the camera 175. Controlling the driving motor 181 to work can drive the gear set 182 to drive the scraper 183 to rotate, and the rotation of the scraper 183 can clean the materials staying on the cover 171 and the transparent sealing plate 172 to prevent the materials from blocking the monitoring and filming of the camera 175. To clear the blockage caused by the bridging phenomenon, manually turn the bolts on the drive motor 181 and the bolts on the cover 171 to remove the drive motor 181 and the cover 171 from the mounting tube 91 to prevent the drive motor 181 and the gear set 182 from entering the material along with the mounting tube 91, thereby preventing the gear set 182 from being stuck by the material. When the camera 175 needs to be used for monitoring again, the drive motor 181 and the cover 171 can be reinstalled on the mounting tube 91 with the bolts.

Through the cooperation of the silicone sleeve 19 and the wire hole 20, the power cord of the vibration motor 95 can be effectively gathered and limited to avoid the power cord of the vibration motor 95 from being scattered randomly, thereby ensuring the safety and stability of the power cord.
