Description

Technical Field

[0001] The invention relates to the technical field of tunnel filling equipment, in particular to a self-propelled tunnel gangue filling device. Background Art

[0002] The waste rock backfill technology is widely accepted because it can control ground subsidence and reduce the rate of waste rock lifting. The waste rock backfill technology is to fill the waste rock produced underground into the excavated coal tunnel to replace the coal pillar. This can not only achieve the goal of not lifting the waste rock to the well, not occupying arable land, protecting the environment, but also extract coal resources that cannot be extracted by conventional methods, thereby increasing the resource output rate;

[0003] When filling the tunnel with gangue, the existing filling method is generally to transport the gangue in a fast motion and throw it into the tunnel. Since the gangue has uneven particle sizes when being transported and thrown, it is easy for larger gangue to fall preferentially into the tunnel under the influence of its own weight when thrown. As a result, when filling, larger gaps are formed between the large pieces of gangue at the bottom due to the falling of larger pieces of gangue, which is easy to cause insufficient filling density during filling due to the existence of larger gaps, thereby affecting the filling stability and the safety of tunnel filling.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, when the conveyor belt drives the gangue to rotate rapidly, the rapid rotation of the conveyor belt will drive the two rollers to rotate synchronously. When the two rollers rotate rapidly, they will drive the crank rod to rotate synchronously. When the crank rod rotates, it will drive the H-plate to shake in the form of an elliptical motion. When the crank rod rotates to the upper fulcrum of the roller, the rotation of the crank rod will drive the H-plate to rotate upward and generate an upward push on the conveyor belt at the bottom center of the conveyor belt. Then, when the crank rod continues to rotate, the rotation of the crank rod will drive the H-plate to slide forward in a certain arc. At this time, when the conveyor belt drives the conveyor belt to shake, the gangue on the conveyor belt It will shake synchronously with the shaking of the conveyor belt. At this time, the larger particles of gangue on the conveyor belt will contact the conveyor belt under their own weight. At the same time, when the conveyor belt shakes, the smaller particles of gangue on the conveyor belt will slide forward in a certain arc with the H-plate under the shaking of the conveyor belt. The smaller gangue will move to the front end of the conveyor belt due to its own fluidity, and thus be thrown first, reducing the uneven filling and insufficient filling density caused by the mixed throwing of large and small gangue, and reducing the settlement or tunnel deformation caused by insufficient gangue filling density after filling, thereby improving the stability of the filling body and the safety of the tunnel.

[0019] 2. In the present invention, when the two rollers are rotating, the two transmission components will be in an up and down rotating state under the rotation of the two rollers as shown in the figure. When one of the transmission components rotates upward, the rotation of the roller will drive the spring rod 2 to rotate upward through the rotating ball on the swash plate. When the spring rod 2 rotates upward, it will drive the limit plate 2 to rotate upward through the limit plate 1 and a plurality of limit shafts. At the same time, when the swash plate rotates, the rotation of the swash plate will squeeze the spring rod 2 through the rotating ball. After the spring rod 2 is squeezed, it will drive the push rod to push the bottom of the triangular frame. When the triangular frame rotates upward, the rotation of the triangular frame will push the conveyor belt upward at the bottom of the conveyor belt. Then, when the swash plate continues to rotate, the transmission component on the other side will The side wall of the conveyor belt is pushed upward at the bottom of the other side of the conveyor belt. At this time, the bottom two sides of the conveyor belt will shake under the up and down rotation of the two transmission components. When the bottom transmission components on both sides of the conveyor belt shake under the rotation, the gangue on the conveyor belt can be gathered to the middle of the conveyor belt, and the concentrated gangue can be thrown centrally under the rapid rotation of the conveyor belt, which helps to fill the gangue into the target area more accurately and reduce the situation where the gangue is scattered on the conveyor belt and accumulates on the edge of the tunnel or around the equipment when thrown. At the same time, it can also reduce the dispersion of gangue during transportation due to the push of the H-plate during the throwing process, thereby improving the concentration and uniformity of filling and throwing.

[0020] When the gear train is in a state of being moved upward, the gear train is moved upwardly and the gear train is moved upwardly, so that the gear train moves relatively smoothly and the gear train is moved along the guide rail, thereby preventing the gear train from moving upwardly and thus causing the gear train to move relatively smoothly.

[0021] 4. In the present invention, when the spring rod 2 is pulled by the rotating ball to reset, the reset movement of the spring rod 2 will squeeze the spring block and drive the spring block to slide inside the long groove when the spring rod 2 is reset. When the spring block slides, it will push the connection end with the arc plate through the middle plate. When the arc plate is pushed, the arc plate will rotate upward under the push of the middle plate. When the arc plate rotates upward, the rotation of the arc plate will push the sliding plate to move upward. When the sliding plate moves upward, several plug rods at its bottom will slide obliquely upward under the guidance of the oblique groove. When the sliding plate slides obliquely upward, it will push the rotating plate through the connecting plate. At the same time, the sliding plate When sliding obliquely upward, the bottom of the conveyor belt will be pushed upward. At the same time, when the rotating plate is pushed by the connecting plate, the rotating plate will rotate under the push of the connecting plate. When the rotating plate rotates, the side wall of the conveyor belt will form a vertical state and block the side wall of the conveyor belt. At this time, the vertical rotating plate combined with the sliding plate pushes the conveyor belt, which can reduce the lateral force exerted on the conveyor belt under the push of the transmission component, and further limit the lateral deviation of the conveyor belt when it is pushed by the transmission component. It can also reduce the falling of gangue due to the deviation of the conveyor belt when the conveyor belt deviates, and at the same time, it can also enhance the stability and throwing effect of the conveyor belt when throwing gangue.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Then, when the motor 205 is started, the conveyor belt 204 will be driven to rotate rapidly through the rotating roller 202. When the conveyor belt 204 rotates rapidly, the gangue will be quickly thrown to the target area to complete the filling purpose.

[0047] When the conveyor belt 204 drives the gangue to rotate rapidly, the rapid rotation of the conveyor belt 204 will drive the two rollers 302 to rotate synchronously.

At this time, the conveyor belt 204 drives the conveyor belt 204 to rotate. During shaking, the gangue on the conveyor belt 204 will shake synchronously with the shaking of the conveyor belt 204. At this time, the larger particles of gangue on the conveyor belt 204 will contact the conveyor belt 204 under their own weight. At the same time, when the conveyor belt 204 shakes, the smaller particles of gangue on the conveyor belt 204 will slide forward in a certain arc with the H-plate 404 under the shaking of the conveyor belt 204. The smaller gangue will move to the front end of the conveyor belt 204 due to its own fluidity, so as to be thrown first, thereby reducing the uneven filling and insufficient filling density caused by the mixed throwing of large and small gangue, and reducing the settlement or deformation of the tunnel due to insufficient gangue filling density after filling, thereby improving the stability of the filling body and the safety of the tunnel.

[0048] When the two rollers 302 rotate, the two transmission components 51 will rotate up and down under the rotation of the two rollers 302. Figure 7When one of the transmission components 51 rotates upward, the rotation of the roller 302 drives the spring rod 2 513 to rotate upward through the rotating ball on the swash plate 511. When the spring rod 2 513 rotates upward, it drives the limit plate 2 516 to rotate upward through the limit plate 1 515 and a plurality of limit shafts. At the same time, when the swash plate 511 rotates, the rotation of the swash plate 511 squeezes the spring rod 2 513 through the rotating ball. After the spring rod 2 513 is squeezed, it drives the push rod 601 to push the bottom of the triangular frame 602. When the triangular frame 602 rotates upward, the rotation of the triangular frame 602 pushes the conveyor belt 204 upward at the bottom of the conveyor belt 204. Then, when the swash plate 511 continues to rotate, the transmission component 51 on the other side of the conveyor belt 204 The bottom pushes the side wall of the conveyor belt 204 upward, and at this time, the two sides of the bottom of the conveyor belt 204 will shake under the up and down rotation of the two transmission components 51. When the bottom transmission components 51 on both sides of the conveyor belt 204 shake under the rotation, the gangue on the conveyor belt 204 can be gathered to the middle of the conveyor belt 204, and the concentrated gangue can be thrown in a concentrated manner under the rapid rotation of the conveyor belt 204, which helps to fill the gangue into the target area more accurately and reduce the situation where the gangue is scattered on the conveyor belt 204 when being thrown. Accumulation at the edge of the tunnel or around the equipment during throwing. At the same time, it can also reduce the dispersion of gangue during transportation due to the push of the H-plate 404 during the throwing process, thereby improving the concentration and uniformity of filling and throwing.

[0049] When one transmission component 51 rotates upward and the other transmission component 51 rotates downward, during the downward rotation of the transmission component 51, the slant plate 511 will pull the second spring rod 513 through the rotating ball on the surface. After being pulled by the rotating ball, the second spring rod 513 will slide in the limit plate 1 515. When the second spring rod 513 slides, it will pull the triangular frame 602 through the push rod 601 to reset it. At the same time, when the second spring rod 513 slides, its surface will squeeze the inclined surface of the triangular frame 602 during the sliding process, and the inclined surface of the triangular frame 602 After being squeezed, the long rod will be driven by the hollow plate 603 to slide upward inside the rectangular groove. When the triangular frame 602 slides upward, it will generate an upward push on the bottom side wall of the conveyor belt 204. When the triangular frame 602 rotates upward, it will provide a certain upward support at the bottom end of the motor 205, which can reduce the deviation when the other transmission component 51 rotates upward and pushes the conveyor belt 204 to concentrate the gangue it transports and transport and throw it, and reduce the situation where the conveyor belt 204 may be affected by the push of the transmission component 51 and the normal transportation and throwing of the gangue may be affected, thereby affecting the working efficiency of this device.

[0050] When the spring rod 513 is pulled by the rotating ball to reset, the reset movement of the spring rod 513 will squeeze the spring block 701 and drive the spring block 701 to slide inside the long groove when the spring rod 513 is reset. When the spring block 701 slides, it will push the connection end with the arc plate 703 through the middle plate 702. When the arc plate 703 is pushed, the arc plate 703 will rotate upward under the push of the middle plate 702. When the arc plate 703 rotates upward, the rotation of the arc plate 703 will push the sliding plate 704 to move upward. When the sliding plate 704 moves upward, several plug rods at its bottom will slide obliquely upward under the guidance of the oblique groove 604. When the sliding plate 704 slides obliquely upward, it will push the rotating plate 706 through the connecting plate 705. At the same time, the sliding plate 70 When the rotating plate 706 is sliding obliquely upward, the bottom of the conveyor belt 204 is pushed upward. At the same time, when the rotating plate 706 is pushed by the connecting plate 705, the rotating plate 706 is rotated under the push of the connecting plate 705. When the rotating plate 706 is rotating, the side wall of the conveyor belt 204 is formed into a vertical state and the side wall of the conveyor belt 204 is blocked. At this time, the vertical rotating plate 706 combined with the sliding plate 704 pushing the conveyor belt 204 can reduce the lateral force on the conveyor belt 204 under the push of the transmission component 51, further limit the lateral deviation of the conveyor belt 204 when it is pushed by the transmission component 51, and reduce the situation that the waste rock falls due to the deviation of the conveyor belt 204 when the conveyor belt 204 deviates, and at the same time, it can also enhance the stability and throwing effect of the conveyor belt 204 when throwing the waste rock.
