Description

Technical Field

[0001] The present invention relates to the technical field of underground mine filling, in particular to underground filling materials and mixing devices. Background Art

[0002] During coal mining, underground filling projects are often required to maintain the stability of the mine and ensure the safety of workers. The filling materials should have a certain strength and stability, be able to fill the voids and cracks in the mine, form a solid support structure, and prevent collapse and roof subsidence.

[0003] There are some coal mine underground filling materials on the market. However, these materials often use traditional materials such as natural sand, gravel, cement, etc., and cannot fully utilize waste resources such as coal gangue. In addition, there are problems such as poor fluidity and long hardening time during the filling process.

[0004] For example: Chinese invention patent CN109736808B: disclosed "an underground mining process that does not require the construction of a tailings pond", its description discloses: "At this stage, sand and gravel aggregates mainly rely on natural sand and gravel, and the production areas are mainly concentrated in the main stream and tributary basins of the Yangtze River and the Yellow River, which cause serious damage to the ecology. Affected by the ban on river mining, a large number of sand and gravel companies in many areas have been closed down, the supply of sand and gravel has been greatly reduced, and the price of concrete has generally risen. In recent years, with the depletion of natural river sand resources and the introduction of measures to ban river sand mining in various places, machine-made sand and gravel have come into being and gradually replaced natural river sand." The above patents can prove the defects of the existing technology.

[0098] Further, such as Figure 2-5 As shown, the stirring and pushing portion includes a chamber 1 302 provided in a turntable 301 and located on one side of a central hole 1 304. The turntable 301 also has two communication ports 303 extending therethrough, located on either side of the chamber 1 302. A rotating shaft 308 is rotatably connected to each of the two communication ports 303 via a bearing. One end of each of the two rotating shafts 308 extends into the chamber 1 302, and a universal joint 309 is connected between one end of the two rotating shafts 308 located in the chamber 1 302.

A capillary 407 is connected between the two airbags 2 406 and the two airbags 1 404. When the stirring and pushing part stirs the material, the airbag 2 406 extends, causing the airbag 1 404 to shrink, and the protective plate 403 rotates toward the center hole 1 304 driven by the airbag 1 404. At this time, when the turntable 301 rotates, it can assist in stirring the material through the side grooves 402. When the stirring and pushing part is deformed, the airbag 2 406 shrinks and the airbag 1 404 extends. At this time, the protective plate 403 rotates and cooperates with the outer side of the turntable 301 to form a complete circular structure, which can further facilitate the turntable 301 to push the material out.

A second motor 603 is fixedly installed on one side of one of the support seats 601, and the output shaft of the second motor 603 is fixedly connected to one end of the screw rod 602. The screw rod 602 is driven to rotate by the second motor 603 to drive the support plate 502 to move, and the turntable 301 can be driven to move in the mixing tank 1 through the support plate 502, so that the mixing of materials can be more uniform, and the turntable 301 can push the material during discharging;

[0107] The bottoms of both sides of the mixing tank 1 are fixedly connected with discharge pipes 7, so that the two discharge pipes 7 can speed up the discharge of materials. A slot is provided on one side of the top of the discharge pipe 7, and a sealing plate 8 is inserted into the slot. The sealing plate 8 can seal the discharge pipe 7 before discharging the material. Pull the sealing plate 8 upwards and remove it to release the sealing plate 8 from the discharge pipe 7.

[0108] The use process of the downhole filling material and mixing device provided by the present invention is as follows:

[0109] The material is added to the mixing tank 1 through the feeding port 2, and then the motor 1 505 and the motor 2 603 are started. The motor 2 603 drives the screw 602 to rotate, which can drive the support plate 502 to move. The support plate 502 can drive the turntable 301 to reciprocate in the mixing tank 1. The motor 1 505 can drive the transmission shaft 503 to rotate through the cooperation of the synchronous wheel 506 and the synchronous belt 507. The transmission shaft 503 can drive the turntable 301 to rotate. During the rotation of the turntable 301, the stirring blade 307 can stir the material, and the setting of the side groove 402 makes it possible to stir the material when the turntable 301 rotates;

[0110] During discharging, the electric push rod 513 pushes the connecting ring 512 away from the turntable 301, and the connecting ring 512 pushes the insertion rod 508 through the positioning rod 511 and the connecting disk 509, so that the insertion rod 508 is separated from the rack 306. At this time, the force of the spring 408 can drive the rack 306 to move, and the rack 306 drives the universal joint 309 to rotate through the gear 310. The universal joint 309 drives the two rotating shafts 308 connected to it to rotate, so that the stirring blade 307 rotates to block the connecting port 303. At the same time, the piston 405 squeezes the airbag 2 406, so that the air pressure in the airbag 2 406 is transported to the airbag 1 404 through the capillary 407, so that the airbag 1 404 stretches and drives the protective plate 403 to rotate, that is, Figure 9 and Figure 10 As shown, the blocking plate 8 is pulled upward to remove the blocking plate 8, and the second motor 603 drives the screw rod 602 to rotate to drive the support plate 502 to move, and the support plate 502 can drive the turntable 301 to reciprocate in the mixing tank 1, and the turntable 301 pushes the material to the discharge pipe 7, and the material is discharged from the discharge pipe 7;

[0111] When used again, the electric push rod 513 drives the connecting ring 512 to move toward the turntable 301, and the connecting ring 512 drives the insertion rod 508 to be inserted into the middle hole 1 304 through the positioning rod 511 and the connecting disk 509. The insertion rod 508 squeezes the rack 306, causing the rack 306 to move. The rack 306 drives the universal joint 309 to rotate through the gear 310, and the universal joint 309 drives the two rotating shafts 308 connected to it to rotate, so that the stirring blade 307 rotates to be perpendicular to the connecting port 303. At the same time, the piston 405 drives the airbag 2 406 to extend, so that the air pressure in the airbag 2 406 is transported to the airbag 2 406 by the capillary 407, causing the airbag 1 404 to shrink and drive the protective plate 403 to rotate, that is, Figure 3 shown.
