Description

Technical Field

[0001] The utility model relates to the technical field of gangue bin construction in coal mines, metal mines and non-metallic mines, and in particular to a gangue bin anti-blocking and dredging system. Background Art

[0002] During the construction of a waste rock silo, one or more rectangular holes are typically drilled in the center of the silo. Excavation is then carried out from top to bottom, allowing the waste rock to flow through the holes and into a tunnel connected to the silo floor. Professional workers then gradually expand the silo downward along this chute. Through a rigorous construction process, the silo is completed to meet the design requirements and meet the full dimensions. Furthermore, the bottom of the silo is designed with a tapered opening, primarily to prevent blockage during the transportation of waste rock or coal stone. During the construction of the silo, waste rock that falls from the silo walls naturally falls through the chute into the underground tunnel below. This design facilitates the timely transfer and transportation of this waste rock.

[0003] However, waste rock and other debris can easily clog the waste chute during transportation. Once blocked, the waste rock cannot be smoothly transferred. This situation not only seriously impacts construction progress but also poses a significant threat to worker safety. Currently, the most common method for clearing the blockage is to use air cannons to blast the blocked waste rock. This method is not only somewhat dangerous but also has limited effectiveness.

[0020] See also Figures 1 to 3A gangue silo anti-blocking and dredging system is provided with a mobile base 1, a lifting mechanism 2 and a dredging and collecting component 3. When gangue is blocked during transportation at the gangue chute, the mobile base 1 is moved to a shaft connected to the bottom of the gangue chute through the existing conveying equipment, and then the dredging and collecting component 3 is moved to the location where the blockage occurs in the gangue chute through the lifting mechanism 2. Finally, the dredging and collecting component 3 dredges the blocked location.

[0021] The lifting mechanism 2 for driving the dredging and collecting assembly 3 to move up and down is composed of a first driving member 4 and a support frame 6 arranged on the mobile base 1, a lifting frame 7 vertically slidingly arranged in the support frame 6, a moving frame 8 vertically slidingly arranged in the lifting frame 7, and a jacking block 9 vertically slidingly arranged in the moving frame 8; in order to adapt to the environment in the mine tunnel, the first driving member 4 is preferably a pneumatic press or a gas-liquid booster, but a reciprocating motor, a cylinder, an electric push rod, etc. can also be used as a replacement. The output shaft of the first driving member 4 passes through the support frame 6 and is connected to the lifting frame 7. When the lifting frame 7 is driven vertically by the first driving member 4 to move upward, the first gear 11 hinged on both sides of the lifting frame 7 rotates under the meshing transmission with the first rack 10 vertically arranged on both sides of the inner wall of the support frame 6, thereby driving The moving frame 8, which is also meshed with the first gear 11 through the second rack 12, moves up. When the moving frame 8 moves up, the second gear 13 rotates under the action of the first rack 10 vertically provided on both sides of the inner wall of the lifting frame 7, thereby driving the jacking block 9 with the second rack 12 to move up. Since a mounting seat 14 is provided on the jacking block 9, and the mounting seat 14 is rotationally connected to the dredging collection component 3, when the jacking block 9 moves up, the dredging collection component 3 is driven to move up synchronously to move the dredging collection component 3 to the blocked position for dredging. After the dredging is completed, the output shaft of the first driving member 4 is moved down to reset the position of the dredging collection component 3 so as to transport the waste rock sent into the dredging collection component 3 during dredging to prevent it from affecting the subsequent dredging operation.

[0022] The dredging and collecting assembly 3 for dredging blocked gangue consists of a rectangular collecting frame 15 rotatably connected to the mounting seat 14, a second driving member 16 arranged at the bottom of the rectangular collecting frame 15, and a dredging block 17 vertically slidingly arranged in the rectangular collecting frame 15; the second driving member 16 adopts the same equipment as the first driving member 4 to adapt to the construction environment in the mine tunnel. The output shaft of the second driving member 16 passes through the rectangular collecting frame 15 and is connected to the dredging block 17. When dredging, the dredging block 17 is driven up and down by the second driving member 16, and the end of the dredging block 17 is set to be conical to reduce the contact area and better dredge the gangue. A vertical limiting rod 20 is also provided on the rectangular collecting frame 15, so that the dredging block 17 slides and cooperates with the limiting rod 20 to increase the stability of the dredging block 17 when moving. After the gangue is loosened, it falls into the rectangular collecting frame 15 and waits for dredging. After completion, the rectangular collecting frame 15 containing the gangue is driven by the lifting mechanism 2 to move down to detach from the gangue bin. Since the rectangular collecting frame 15 is rotatably connected to the mounting seat 14 and a limit block is provided on one side to prevent the rotation of the rectangular collecting frame 15, the rectangular collecting frame 15 can only rotate to one side, and the rectangular collecting frame 15 has a certain slope, with the lower part located on the rotatable side, and an opening is provided at the lower part of the rectangular collecting frame 15. Therefore, when the rectangular collecting frame 15 detaches from the gangue bin, under the action of gravity, the gangue slides to the lower part of the rectangular collecting frame 15 and falls into the bin of a special gangue transport vehicle from the opening. Finally, a torsion spring is provided at the connection between the mounting seat 14 and the rectangular collecting frame 15 so that the rectangular collecting frame 15 can be reset after the gangue is cleared. It is also used to slow down the speed at which the gangue falls into the transport vehicle, thereby improving the safety of the staff.

[0023] The mobile base 1 used to drive the movement of the equipment consists of a base 18 and a universal wheel 19 arranged at the bottom of the base 18. The first driving member 4 is arranged on the base 18, and the support frame 6 is arranged on the base 18 through the column 5 to complete the connection. When the gangue bin needs to be dredged, the equipment can be moved to a suitable position by connecting the base 18 to equipment such as a tractor.

[0024] The working principle of the utility model is as follows: when the gangue bin is blocked and needs to be unblocked, the device is moved to the bottom shaft connected to the gangue chute, and then the lifting frame 7 is driven to move upward by the first driving member 4. Since the first rack 10 on the support frame 6 is engaged with the first gear 11 on the lifting frame 7, the first gear 11 is driven to rotate. Since the first gear 11 is engaged with the second rack 12 on the moving frame 8, the moving frame 8 is synchronously driven to move upward. When the moving frame 8 moves upward, under the action of the first rack 10 on the lifting frame 7, the second gear 13 rotates, driving the jacking block 9 Move upward and adjust the lifting height of the first driving member 4 according to the actual blockage situation. When the lifting block 9 drives the rectangular collecting frame 15 to move to the blocked position, start the second driving member 16, and the second driving member 16 drives the dredging block 17 to move up and down, so that the blocked gangue is loosened until it falls into the rectangular collecting frame 15. After the dredging is completed, the first driving member 4 drives the rectangular collecting frame 15 to reset. Under the action of gravity, the gangue slides to the lower part of the rectangular collecting frame 15 and falls into the bin of a special gangue transport vehicle from the opening so that the staff can collect and transport it.
