[0002] The coal mine tunneling machine is a large mechanized equipment used for coal mine construction, which can efficiently and safely complete coal mine excavation, support and slag removal operations.

[0003] The patent with patent announcement number CN222848216U relates to a bottom slag removal device of a tunneling machine, which includes a V-shaped support plate, both ends of which are hingedly connected with turning plates; a plurality of groups of through holes are formed around both ends of the V-shaped support plate, and a corresponding through hole is also formed at one end of the turning plate; a screw is arranged inside the through hole; a support frame is fixedly connected to one side of the turning plate, and a push plate is fixedly connected to one side of the support frame; when the tunneling machine is driving forward, the rubble can be pushed to the sides of the tunnel along the V-shaped slope to reduce the phenomenon of accumulation at the bottom of the track, thereby reducing the possibility of slag accumulation at the bottom of the machine body and ensuring the normal operation and driving efficiency of the tunneling machine. The V-shaped plate bottom contacts the tunnel bottom, which can provide support for the tunneling machine and increase the stability of the machine body, reducing the machine body shaking or tilting caused by uneven or soft ground.

[0030] The circumferential surface of the connecting frame 8 is fixedly installed with a rectangular block 10, the side of the fixed plate 3 close to the rectangular block 10 is fixedly installed with a limiting block 11, a U-shaped groove is formed in the side of the limiting block 11 close to the rectangular block 10, and through unscrewing the screw 5, the slag removal plate 9 can be quickly disassembled, so that the maintenance time can be greatly shortened, and the assembly and disassembly of the slag removal plate 9 can be quickly completed in the space-limited mine.

[0031] ​The fixed plate 3 is fixedly installed with a support plate 12 on one side close to the mounting frame 4, and the slag removal plate 9 is provided with a butt joint groove on one side close to the support plate 12, so that the slag removal plate 9 can efficiently concentrate the slag soil missed by the shovel plate 1 on both sides of the mine during the tunneling process, and the subsequent unified treatment is facilitated.

[0032] During the operation of the embodiment, the worker moves the cylindrical rod 7 downward to drive the connecting frame 8 to move downward, and the connecting frame 8 drives the slag removal plate 9 and the rectangular block 10 to move downward as a whole, and in the moving process, the rectangular block 10 is attached to the U-shaped groove of the limiting block 11, so that the rotation angle of the cylindrical rod 7 is accurately constrained to ensure that it moves downward at the preset angle; when the connecting frame 8 contacts the top of the hollow sleeve 6, the screw 5 is automatically aligned with the internal threaded blind hole, and the worker immediately tightens the screw 5 to make it rotate into the aligned internal threaded blind hole, thereby completing the fixation of the cylindrical rod 7; through the design of the limiting block 11, the positions of the screw 5 and the internal threaded blind hole can be automatically aligned, the time for the worker to repeatedly adjust the angle is saved, and thus the efficiency of the mine slag removal is improved; when the slag removal plate 9 moves downward, the butt joint groove of the slag removal plate 9 is tightly attached to the support plate 12 to form a stable support; when the tunneling machine body advances in the mine, the hydraulic driving device drives the shovel plate 1 to move, and the shovel plate 1 drives the star wheel device 2 and the fixed plate 3 to move as a whole; in this process, the slag removal plate 9 moves synchronously and guides the contacted gravel and soil to the two sides of the shovel plate 1; at this time, the support plate 12 provides continuous support for the slag removal plate 9 to prevent the slag removal plate 9 from deviating under the impact of the slag soil and ensure that it stably pushes the missed gravel and soil of the shovel plate 1 to the two sides of the mine to form a concentrated accumulation zone; through the provision of stable support for the slag removal plate 9, the slag removal plate 9 can efficiently concentrate the missed slag soil of the shovel plate 1 on both sides of the mine during the tunneling process, and the subsequent unified treatment is facilitated; when the slag removal plate 9 needs to be maintained or replaced, the worker first unscrews the screw 5 to make it completely exit the internal threaded blind hole of the cylindrical rod 7 and retreat to the initial position, thereby releasing the fixation of the cylindrical rod 7, and then vertically upwardly extracts the cylindrical rod 7; in this process, the cylindrical rod 7 drives the connecting frame 8 to move upward, and the connecting frame 8 drives the slag removal plate 9 and the rectangular block 10 to move upward as a whole; after the cylindrical rod 7 completely separates from the hollow sleeve 6, the maintenance or replacement of the slag removal plate 9 can be performed; through the unscrewing of the screw 5, the slag removal plate 9 can be quickly disassembled, the maintenance time can be greatly shortened, and the assembly and disassembly of the slag removal plate 9 can be quickly completed in the mine with limited space.

[0033] Please refer to Figure 1 - Figure 8On the basis of the above-mentioned embodiments, in another embodiment of the present application, the support plate 12 is provided with auxiliary devices for improving the efficiency of dismounting the cylindrical rod 7 and reinforcing devices for improving the stability of the slag removal plate 9; the auxiliary devices include a rectangular box 131 fixedly installed on the surface of the support plate 12, a sliding rod 132 slidingly penetrating the top of the rectangular box 131, a sleeve plate 133 fixedly installed on the top of the sliding rod 132, springs 134 provided between the sliding rod 132 and the rectangular box 131, the sliding rod 132 in contact with the inner wall of the circular hole, a circular groove opened in the top of the sleeve plate 133, and the elastic potential energy stored by the springs 134 assisting the dismounting of the slag removal plate 9, which not only reduces the dismounting strength, but also shortens the downtime and reduces the influence of maintenance on the construction progress of the mine.

[0034] A circular rod 135 is fixedly installed on the surface of the sliding rod 132, one side of the rectangular box 131 close to the circular rod 135 is provided with a sliding groove, the circular rod 135 is in contact with the inner wall of the sliding groove, and the circular rod 135 cooperates with the arc-shaped piece 137 to further enhance the stability of the sliding rod 132 during movement, thereby providing reliable auxiliary thrust for the upward movement of the cylindrical rod 7.

[0035] A through groove is opened in the inner wall of the sleeve plate 133, a linking block 136 is fixedly installed on the inner wall of the through groove, the arc-shaped piece 137 is provided on the side of the linking block 136 close to the circular groove, the arc-shaped piece 137 itself has elasticity, the arc-shaped piece 137 is tightly fitted with the circumferential surface of the cylindrical rod 7 under the elastic action, and the sleeve plate 133 can stably push the cylindrical rod 7 to move upward.

[0036] The reinforcing device includes a mounting box 141 fixedly installed on the surface of the support plate 12, a sleeve rod 142 slidingly installed on the inner wall of the mounting box 141, fixed pieces 143 fixedly installed on the circumferential surface of the sleeve rod 142, an L-shaped frame 144 fixedly installed on the side of the mounting box 141 close to the fixed pieces 143, a buffer block 145 fixedly installed on the inner wall of the mounting box 141, the sleeve rod 142 fixedly connected with the circular rod 135, the sleeve rod 142 in contact with the buffer block 145, the fixed pieces 143 in contact with the inner wall of the L-shaped frame 144, and the impact force of the sliding rod 132 on the inner wall of the rectangular box 131 reduced by the deceleration function of the buffer block 145, thereby ensuring the safety and reliability of the entire resetting process.

[0037] A moving rod 146 slidingly penetrates the side of the mounting box 141 away from the L-shaped frame 144, a rubber plate 147 is fixedly installed on the side of the moving rod 146 away from the mounting box 141, springs 148 are provided between the rubber plate 147 and the mounting box 141, an arc surface is opened in the side of the rubber plate 147 away from the mounting box 141, the rubber plate 147 is actively pressed by the slag removal plate 9, the rubber plate 147 applies uniform contact pressure to the slag removal plate 9 under the reverse force, and the installation stability of the slag removal plate 9 is further enhanced.

[0038] When the cylindrical rod 7 moves downward along the hollow sleeve 6, the circumferential surface of the cylindrical rod 7 is in contact with and extrudes the curved surface of the arc-shaped sheet 137, so that the arc-shaped sheet 137 is elastically deformed. Under the elastic action, the deformed arc-shaped sheet 137 is tightly attached to the circumferential surface of the cylindrical rod 7. At this time, the cylindrical rod 7 continues to move downward and is attached to the circular groove of the sleeve plate 133. Then, the cylindrical rod 7 drives the sliding rod 132 to move downward synchronously through the sleeve plate 133. The sliding rod 132 compresses the spring 134, so that the spring 134 is elastically deformed and stores elastic potential energy. When the slag removal plate 9 is disassembled, the worker rotates out the screw 5. At this time, the spring 134 releases the stored elastic potential energy and pushes the sliding rod 132 to move upward. The sliding rod 132 drives the cylindrical rod 7 to move upward through the sleeve plate 133, so that the pulling force required for manually extracting the cylindrical rod 7 is reduced. The elastic potential energy stored by the spring 134 assists the disassembly of the slag removal plate 9. Not only the strength of disassembly is reduced, but also the downtime is shortened, and the influence of maintenance on the construction progress of the mine is reduced. When the sliding rod 132 moves, it drives the circular rod 135 to move along the sliding groove. When the circular rod 135 moves in the sliding groove, the sliding groove provides accurate guidance for the circular rod 135, so that the circular rod 135 always keeps stable during the movement. When the spring 134 restores and pushes the sliding rod 132 to move upward, the movement of the sliding rod 132 is more stable and does not shake or tilt. When the sleeve plate 133 moves upward to the initial position, the cylindrical rod 7 continues to move upward and is completely separated from the circular groove. At the same time, the contact surface between the cylindrical rod 7 and the arc-shaped sheet 137 gradually decreases. Under the action of the elastic restoring force of the arc-shaped sheet 137, the arc-shaped sheet 137 quickly rebounds. Through the cooperation of the circular rod 135 and the arc-shaped sheet 137, the stability of the sliding rod 132 during the movement is further enhanced, so as to provide reliable auxiliary thrust force for the upward movement of the cylindrical rod 7.

[0039] When the round rod 135 moves downward, it drives the sleeve rod 142 to move downward synchronously, so that the sleeve rod 142 is out of contact with the buffer block 145, and at the same time, the sleeve rod 142 drives the fixed plate 143 to move downward along the L-shaped frame 144 smoothly; when the spring 134 releases the elastic potential energy and pushes the sliding rod 132 to move upward, the round rod 135 drives the sleeve rod 142 to move upward synchronously, and the sleeve rod 142 is in contact with the buffer block 145 in the movement, and the buffer block 145 absorbs kinetic energy through elastic deformation, effectively slowing down the moving speed of the sleeve rod 142, and this buffering effect is transmitted to the sliding rod 132 through the round rod 135, so that the sliding rod 132 is smoothly reset to the starting position at a controlled speed, and through the deceleration function of the buffer block 145, the impact force of the sliding rod 132 on the inner wall of the rectangular box 131 is reduced, which not only can avoid damage caused by collision, but also can ensure the safety and reliability of the entire resetting process; when the slag removal plate 9 is installed, the slag removal plate 9 moves downward and is in contact with the arc surface of the rubber plate 147 and applies uniform pressure, forcing the rubber plate 147 to move in the direction of the carrying box 141; in this process, the rubber plate 147 drives the moving rod 146 to move synchronously, and at the same time, the rubber plate 147 moves and compresses the elastic sheet 148, forcing the elastic sheet 148 to elastically deform, and the deformed elastic sheet 148 generates a reverse force, pushing the rubber plate 147 and the slag removal plate 9 to form a tight and flexible fit, providing additional support for the slag removal plate 9, further improving the stability of the fit between the slag removal plate 9 and the support plate 12, and through the active extrusion of the slag removal plate 9 on the rubber plate 147, the rubber plate 147 applies uniform contact pressure on the slag removal plate 9 under the reverse force, further enhancing the installation stability of the slag removal plate 9.
