[0002] Backfill mining refers to a mining method that uses backfill materials to fill the goaf during ore dropping, transportation and other operations. The purpose of backfilling is to support the rocks on both sides of the goaf and to create a foothold for the continued stratified mining above. The filling method is usually: first, use the roof and the rear tail beam to support the rock layer above the goaf, then place a bag in the goaf at the lower end of the rear tail beam, open the bag and release the paste into the bag, and after the paste solidifies, the roof and the rear tail beam move to the unmined coal seam area to complete the filling of the goaf of the coal mine, and make the lower end of the rear tail beam located in the goaf again.

In this application, the transmission gear motor and the regulating rod motor adopt existing models.

[0024] When preparing for filling, first support the rock wall at the upper end of the goaf with the top plate 102 and the rear tail beam 101, then use several top plates 102 and rear tail beams 101 to arrange to fully support the goaf, and then prepare for filling; first start the transmission component, the transmission component controls the bag opening component to descend to a position close to the ground, and then manually install a bag on the bag opening components of different rear tail beams 101, and then several bag opening components are raised to the lower end of the rear tail beam 101, and the bags are opened while being raised, so that the bags initially fill the goaf of the coal mine, and then fill the paste into the bags, and fully open the bags, so that the paste and the bags completely fill the goaf of the coal mine, and then The cloth bag opening component is then controlled to release the cloth bag, and the cloth bag hook 302 is electrically or pneumatically driven to realize the function of simple opening and closing. When the cloth bag hook 302 is closed, the cloth bag can be fixed, and when the cloth bag hook 302 is opened, the cloth bag can be released. Then the transmission component controls the cloth bag opening component to be retracted into the rear tail beam 101, and at the same time, the two door panels 401 are driven to close during the retraction to ensure the sealing inside the rear tail beam 101. After the paste solidifies, the coal mine goaf is filled. At this time, the roof 102 drives the rear tail beam 101 to move toward the coal mine mining area. The rear tail beam 101 leaves the filled goaf and arrives at the unfilled goaf, preparing for the next filling.

[0025] In order to solve the problem that it is unsafe and inefficient to install the cloth bag manually, and to achieve the effect of manually hanging the cloth bag on the cloth bag opening component and supporting the cloth bag to open, a cloth bag opening component is provided, and the cloth bag opening component includes an adjusting rod 301, and both ends of the adjusting rod 301 are rotatably connected to a fixed block 304, one of the fixed blocks 304 is provided with an adjusting rod motor, the adjusting rod motor can drive the adjusting rod 301 to rotate, and the fixed block 304 is vertically slidably connected to the rear tail beam 101, and a plurality of hook slides 303 are provided on the adjusting rod 301, the same end of the plurality of hook slides 303 is concentratedly distributed, and the other end of the plurality of hook slides 303 is dispersedly distributed, and the hook slide 303 is slidably connected to a cloth bag hook 302, and the cloth bag hook 302 is used to hang the cloth bag.

[0026] When preparing to fill, the transmission assembly drives the fixed block 304 to descend, the fixed block 304 drives the adjusting rod 301 to descend, the adjusting rod 301 drives the cloth bag hook 302 to descend to a position close to the ground of the goaf, and then the cloth bag is installed on the cloth bag hook 302, and then the transmission assembly drives the fixed block 304 to rise, the fixed block 304 drives the adjusting rod 301 to rise, the adjusting rod 301 drives the cloth bag hook 302 to rise, and the cloth bag hook 302 drives the cloth bag to rise. During the process of the fixed block 304 rising, the adjusting rod electric The motor of the adjusting rod drives the adjusting rod 301 to rotate, and the adjusting rod 301 drives the hook slide slot 303 to rotate. The cloth bag hook 302 begins to slide in the hook slide slot 303 under the action of gravity. At the same time, the distance between several cloth bag hooks 302 becomes farther, and the cloth bag hook 302 drives the cloth bag to open; when the cloth bag rises to the bottom of the rear tail beam 101, the paste is filled into the cloth bag, and the paste automatically adapts to the gap between the rear tail beam 101 and the goaf, and the paste drives the cloth bag to fill the gap between the rear tail beam 101 and the goaf.

[0027] In order to achieve the effect of convenient operation of the cloth bag opening assembly, a transmission assembly is provided, which includes a rotating rod 203, which is arranged above the adjusting rod 301, and the rotating rod 203 is rotatably connected in the rear tail beam 101.

[0028] When it is necessary to lower the cloth bag opening assembly, first drive the transmission gear 201 to rotate, the transmission gear 201 drives the driven gear 202 to rotate, the driven gear 202 drives the rotating rod 203 to rotate, the rotating rod 203 drives the spiral gear 204 to rotate, so that the chain 206 rotates and disengages from the spiral gear 204, and the cloth bag opening assembly begins to descend under its own gravity; when it is necessary to raise the cloth bag opening assembly, the transmission gear 201 is driven in the reverse direction to rotate, the transmission gear 201 drives the chain 206 to wrap around the spiral gear 204, and the chain 206 pulls the cloth bag opening assembly to rise. During the winding process of the chain 206, since the tooth top part of the spiral tooth 204 is rounded and the area is small, it can ensure that the chain 206 will not be entangled in the tooth top position of the spiral tooth 204, so that the chain 206 can be well wound in the spiral groove between the spiral teeth 204, avoiding the chain 206 from being entangled in one place and forming accumulation.

When the hook 305 on the fixed block 304 contacts the hook 305 on the linkage rod 402, the two hooks 305 are hooked with each other, and the hook 305 continues to rise. The hook 305 drives the other hook 305 to rotate, and the other hook 305 drives the linkage rod 402 to rotate. The linkage rod 402 drives the connecting rod 405 to rotate. At the same time, the linkage rod 402 drives the torsion spring 403 to undergo elastic deformation, and the connecting rod 405 drives the door panel 401 to move.
