Description

Technical Field

[0001] The invention relates to the technical field of mine filling material conveying, in particular to a mine filling material conveying device. Background Art

[0002] Mine filling refers to the process of filling or refilling the voids below the surface with corresponding ore waste or useless ore during mining, so as to maintain the stability of surface or underground projects, reduce surface subsidence and support projects, and achieve the purpose of environmental protection and resource utilization.

[0003] Traditional mine filling is to use filling equipment to mix coal gangue, fly ash and other materials evenly to form filling materials, and then transport the filling materials to the mouth of the cavity to be filled, and then use assembled pipes to transport the filling materials to the depth of the cavity. As the filling area increases, the assembled pipes are dismantled, and the cross-sectional area of ​​the cavity is larger than the cross-sectional area of ​​the pipes. Therefore, it is difficult to gradually fill the cavity using only pipes with fixed angles. A large amount of filling materials accumulates at the pipe mouth and slowly flows to the edge of the cavity over time. Therefore, during the filling process, it is necessary to stop for a period of time after each large amount of filling to give the filling materials time to flow. The entire filling process takes a long time, and after each filling material solidifies, workers are required to gradually dismantle the pipes and pipe support structures, which increases the investment in labor costs and further increases the time spent on filling.

[0039] First, the transport vehicle 11 is transported to the depth of the mine, and the raw materials required for filling are transported to the vicinity of the transport vehicle 11. At this time, the raw materials are sent to the material mixing rack 12 for mixing through the loading rack 13, and the opening and closing rack 14 is opened to transport the completely mixed raw materials to the storage rack 15 for storage, and the raw materials are continued to be mixed and stirred through the material mixing rack 12. The storage rack 15 and the material mixing rack 12 are separated by the opening and closing rack 14, and the mixed raw materials in the storage rack 15 are transported to the conveying telescopic rack 22 through the conveying pump 21, and the raw materials are discharged into the mine through the swinging discharge rack 23. The discharging position of the swinging discharge rack 23 is controlled by the reciprocating pusher and the auxiliary traction rack 24, so that the swinging discharge rack 23 discharges the materials in a serpentine trajectory, and the mine is filled with partitioned materials. When the area is filled, the auxiliary traction rack 24 is connected to the transport vehicle 11.

[0047] See also Figure 2 and Figure 5 The auxiliary traction frame 24 includes a winding drum 241, the top of the storage tank 151 is rotatably connected with the winding drum 241, the rear end of the storage tank 151 is fixedly installed with a motor 242 through a motor seat, the output shaft of the motor 242 is fixedly connected to the winding drum 241 through a coupling, and the surface of the winding drum 241 is symmetrically fixedly connected with a traction wire rope 243, and the ends of the traction wire rope 243 on the front and rear sides are fixedly connected to the upper ends of the front and rear sides of the mobile pipe sleeve 224; the winding drum 241 is driven to rotate by the motor 242, so that the traction wire rope 243 is wound, and the mobile pipe sleeve 224 is pulled to change the discharge position of the mixed raw materials.

[0048] See also Figure 2 and Figure 5The reciprocating pusher is a linkage frame 25, which includes a right-angle bracket 251. The right-angle bracket 251 is fixedly installed on the upper end of the storage tank 151, and an electric telescopic rod 252 is fixedly installed on the lower end of the horizontal section of the right-angle bracket 251. A fixed cylinder 253 is fixedly installed on the telescopic end of the electric telescopic rod 252. A tilting rod 254 is hinged at the lower end of the fixed cylinder 253, and the end of the tilting rod 254 is hinged to the left end of the mobile sleeve 224; the fixed cylinder 253 is driven up and down by the electric telescopic rod 252, thereby driving the tilting rod 254 to move while changing its tilt angle, and the tilting rod 254 drives the mobile sleeve 224 to move right and left.

[0049] See also Figure 2 and Figure 6 A sprocket 1 2321 is fixedly installed at the rear end of the cylindrical cam 233, and a sprocket 2 2322 is fixedly installed at the left end of the winding drum 241. The sprocket 1 2321 and the sprocket 2 2322 are connected to each other through a toothed chain belt 2323. The diameter of the sprocket 2 2322 is larger than the diameter of the sprocket 1 2321. The winding drum 241 drives the sprocket 2 2322 to rotate, and with the cooperation of the toothed chain belt 2323, the sprocket 1 2321 rotates together, thereby driving the cylindrical cam 233 to rotate.

[0050] The reel 241 is driven to rotate forward by the forward rotation of the motor 242, thereby driving the traction wire rope 243 to reel up and driving the mobile sleeve 224 to move rightward. At the same time, the motor 242 drives the sprocket 2322 to rotate. With the cooperation of the toothed chain belt 2323, the sprocket 1 2321 drives the cylindrical cam 233 to rotate, thereby driving the ball head tube 231 to swing back and forth. When the motor 242 rotates in the reverse direction, the electric telescopic rod 252 drives the fixed cylinder 253 to move downward, thereby driving the tilting rod 254 to move and tilt, driving the mobile sleeve 224 to move leftward. Move, and at the same time, the motor 242 continues to drive the ball head tube 231 to swing back and forth. In the whole discharging process, zoned discharging is carried out, and the telescopic conveying frame 22 moves back and forth in the fixed area. At the same time, the swinging discharging frame 23 swings in the front and back directions throughout the whole process to carry out zoned material laying. It should be noted that when the motor 242 rotates forward to drive the traction wire rope 243 to reel in, the electric telescopic rod 252 drives the fixed cylinder 253 to move upward, and correspondingly, when the electric telescopic rod 252 drives the fixed cylinder 253 to move downward, the traction wire rope 243 is unwound.

[0051] In addition, the reciprocating driving member can also adopt a hydraulic push rod, which drives the movable sleeve 224 to move back and forth. When the hydraulic push rod drives the movable sleeve 224 to move slightly left and right, the motor 242 drives the cylindrical cam 233 to rotate, thereby driving the ball head tube 231 to swing back and forth. At the same time, the winding drum 241 winds up the traction wire rope 243 to assist in pulling the movable sleeve 224 to move right.

[0052] Working principle of the present invention: Step 1: First, the device is transported to the deep of the mine by the transport vehicle 11, and the raw materials required for filling are transported to the vicinity of the transport vehicle 11. At this time, the raw materials are sent to the material mixing rack 12 for mixing through the loading rack 13, and the opening and closing rack 14 is opened to transport the completely mixed raw materials to the storage rack 15 for storage, and the raw materials are continued to be mixed and stirred through the material mixing rack 12.

[0053] Step 2: The material storage rack 15 and the material mixing rack 12 are separated by the opening and closing rack 14 , and the mixed raw materials in the material storage rack 15 are transported to the transport telescopic rack 22 by the transport pump 21 .

[0054] The third step: discharge the raw materials into the mine through the swinging discharge rack 23, and control the discharge position of the swinging discharge rack 23 through the reciprocating pusher and the auxiliary traction frame 24, so that the conveying telescopic frame 22 can cooperate with the swinging discharge rack 23 that swings back and forth in the front and rear directions when it is extended and retracted left and right, so as to carry out regional material laying and filling inside the mine. When the area is fully laid, the conveying telescopic frame 22 and the swinging discharge rack 23 are transported to the next area for material laying and filling by the transport vehicle 11 until the mine is completely filled.
