Description

Technical Field

[0001] The invention belongs to the technical field of mixing equipment, and in particular relates to a mixing device for mine backfill materials. Background Art

[0002] As industry develops faster and faster, people's demand for minerals is getting bigger and bigger. Continuous mining has left many mines on the ground that need to be processed and backfilled. The mine backfill material is not simple soil, but different materials need to be added and mixed.

[0003] In the prior art (Announcement No. CN217016407U, Patent Name: A Mixing Device for Mine Backfill Materials), one side of the fixed plate is fixedly connected to the drive motor through a rotating shaft. When working, the material to be mixed is put from the feed hopper into the mixing box, and then the drive motor is started to drive the fixed plate to rotate. The fixed plate drives the stirring paddle to rotate to mix the material. Under the action of the stirring paddle, the material is stirred while moving forward. When the material moves to the bottom of the conveying blade, the conveying blade quickly falls into the feeding mechanism under the action of the stirring paddle to discharge the material. During the feeding process, the material can be further mixed to make the mixing more uniform, so that the material can be stirred while being discharged when the feeding is not cut off, thereby solving the problem that the transmission mixing device can only stir the same batch and improve the mixing efficiency. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art.

[0004] In the existing device, too much raw material is added at one time during the feeding, and the device needs to stir and mix laboriously, which affects the mixing speed.

[0017] A mixing device for mine backfill materials of the present invention:

[0018] In the mixing device for backfill materials in the mine, the stirring shaft drives the transmission belt to move, and the transmission belt drives the rotating shaft and the half gear to rotate. Because the teeth are meshed with the half gear, the teeth can make the half gear drive the reciprocating plate to reciprocate, and the reciprocating plate drives the plug plate to reciprocate. The plug plate can block the feed inclined box during the reciprocating motion. The feed speed can be effectively controlled by reciprocatingly blocking the feed inclined box, which can meet different feed speeds and avoid the one-time addition of raw materials, which requires laborious stirring and mixing, affecting the mixing speed. The material is fed intermittently to ensure the uniformity of the feed and the stable operation of the equipment. When the material to be mixed is accumulated on the plug plate during the blocking of the feed inclined box, dust will be generated inside the mixing and stirring kettle due to mixing collision. When the blocking of the feed inclined box is completed, the material to be mixed will squeeze the dust floating in the mixing and stirring kettle back into the mixing and stirring kettle to prevent the dust generated during mixing from floating and causing environmental pollution.

[0019] The mixing device for backfill materials in the mine, when the rotating shaft rotates to drive the teardrop-shaped collision block, the teardrop-shaped collision block pushes the arc plate to rise, the arc plate pushes the extrusion plate to rise through the extrusion rod, the extrusion plate squeezes the hydraulic oil in the hydraulic box, the extruded hydraulic oil enters the connecting pipe and pushes the piston plate to move, the piston plate drives the collision ball to collide with the surface of the feed inclined box through the connecting rod, so that the feed inclined box vibrates, prevents material from accumulating in the feed inclined box, realizes the dredging of the material inside the feed inclined box, and realizes the smoothness of feeding.

[0020] The mixing device for backfilling materials in the mine, the collision ball squeezes the gas in the connecting pipe when moving, and the gas enters the expansion bag through the air inlet, thereby expanding the expansion bag. The expansion bag expands back and forth and then shrinks to destroy the accumulation of materials, effectively preventing the materials from adhering to the inner wall of the feed inclined box. At the same time, the squeezing of the materials by the expansion bag during expansion is conducive to the feeding of the materials, thereby improving the overall functionality and practicality of the equipment.

[0021] The mixing device for backfill materials in the mine, when mixing is completed, because the driving rod drives the rotating disc to rotate clockwise, the inclined surface of the pawl cannot drive the ratchet disc to move, so the pawl retracts into the U-shaped frame, and the spiral spring can pull the L-shaped moving rod to retract, and the blocking plate blocks the discharge box to prevent the material from escaping from the discharge box during mixing. When discharging is required, the servo motor drives the driving rod to move counterclockwise, so that the straight surface of the pawl is stuck in the tooth mouth of the ratchet disc, and the pawl drives the ratchet disc to rotate counterclockwise, and the ratchet disc is rotated counterclockwise. The wheel disc drives the annular guide rotating plate to move. Because the L-shaped moving rod is in the reciprocating guide groove on the annular guide rotating plate, the L-shaped moving rod moves back and forth horizontally in the reciprocating guide groove. The L-shaped moving rod pulls the push plate and the I-shaped slide plate to move. The I-shaped slide plate drives the guide slot plate to move. Because the guide slot plate guides the slide rod, the slide rod drives the blocking plate to reciprocate, thereby discharging the material intermittently to ensure the uniformity of the discharging and prevent excessive material from clogging the discharging box and affecting the discharging speed.

[0022] The mixing device for backfill materials in the mine, when the sealing plate performs reciprocating motion, the sealing plate drives the hinge seat one to move, the hinge seat one drives the pulling plate to move, and the pulling plate pulls the V-shaped pressure plate through the hinge seat two to perform reciprocating up and down lifting motion, the V-shaped pressure plate presses down the material falling into the discharge box to prevent excessive accumulation of material affecting the discharge, ensures smooth discharge, increases the discharge speed, ensures the subsequent processing quality, and improves the stability of the device.

These agglomerated raw material particles are often difficult to be effectively dispersed during the mixing process. Even after stirring, the mixed raw materials may still contain a large amount of agglomerates. After mixing, the materials will block the discharge box 11 during the discharge process, which requires manual unblocking. A material discharge mechanism 7 is provided on the top of the blocking plate 609. The material discharge mechanism 7 includes an articulated seat 701 fixedly connected to the top of the blocking plate 609, and the side wall of the articulated seat 701 is rotatably connected to a pull plate 702. The pull plate 702 is away from one end of the articulated seat 701. It is rotatably connected with an articulated seat 2 703, and the side wall of the articulated seat 2 703 is fixedly connected with a V-shaped pressure plate 704. Such an arrangement is that when the sealing plate 609 performs reciprocating motion, the sealing plate 609 drives the articulated seat 1 701 to move, and the articulated seat 1 701 drives the pulling plate 702 to move, and the pulling plate 702 thereby pulls the V-shaped pressure plate 704 through the articulated seat 2 703 to perform up and down reciprocating lifting and lowering motions. The V-shaped pressure plate 704 presses down the materials falling into the discharge box 11 to prevent excessive accumulation of materials affecting the discharge, thereby ensuring smooth discharge, increasing the discharge speed, ensuring the subsequent processing quality, and improving the stability of the device.

[0052] The working principle of a mixing device for backfill materials in a mine pit is as follows: when working, the material to be mixed is put into the feed port 103, and a proper amount of water is added from the water inlet 106, and then the servo motor 202 is started to drive the driving rod 203 to rotate clockwise, and the driving rod 203 drives the belt 205 to move through the first belt pulley 204, so that the belt 205 drives the second belt pulley 206 and the rotating rod 207 to rotate, and the rotating rod 207 drives the driving gear 209 to rotate, and the driving gear 209 drives the driven gear 210 and the stirring shaft 211 to rotate, and the stirring shaft 211 drives the stirring paddle 212 to mix the materials in the mixing and stirring kettle 105;

[0053] The stirring shaft 211 drives the transmission belt 307 to move, and the transmission belt 307 drives the rotating shaft 302 and the half gear 303 to rotate. Because the teeth 304 are meshed with the half gear 303, the half gear 303 can drive the reciprocating plate 305 to reciprocate through the teeth 304, and the reciprocating plate 305 drives the plugging plate 306 to reciprocate. The plugging plate 306 can block the feed inclined box 104 during the reciprocating motion. The feed speed can be effectively controlled by reciprocatingly blocking the feed inclined box 104, and different feed speeds can be met. Avoid adding raw materials at one time, which requires laborious stirring and mixing, affecting the mixing speed, and feed the materials intermittently to ensure the uniformity of the feeding and the stable operation of the equipment. When the materials to be mixed are blocked in the feed inclined box 104, they are piled on the plug plate 306, and dust is generated inside the mixing and stirring kettle 105 due to mixing and collision. When the feed inclined box 104 is blocked, the materials to be mixed squeeze the dust in the mixing and stirring kettle 105 back into the mixing and stirring kettle 105, preventing the dust generated during mixing from floating and causing environmental pollution.

[0054] When the rotating shaft 302 rotates and drives the teardrop-shaped collision block 401, the teardrop-shaped collision block 401 pushes the arc plate 402 to rise, and the arc plate 402 pushes the extrusion plate 407 to rise through the extrusion rod 406. The extrusion plate 407 squeezes the hydraulic oil in the hydraulic box 404. The extruded hydraulic oil enters the connecting pipe 41 and pushes the piston plate 42 to move. The piston plate 42 drives the collision ball 44 to collide with the surface of the feed inclined box 104 through the connecting rod 43, so that the feed inclined box 104 vibrates to prevent materials from accumulating on the feed inclined box 104. In the material inclined box 104, the material inside the feed inclined box 104 is unblocked to achieve smooth feeding. The collision ball 44 squeezes the gas in the connecting pipe 41 when moving, and the gas enters the expansion airbag 46 through the air inlet 45, thereby expanding the expansion airbag 46. The expansion airbag 46 expands back and forth and then shrinks to destroy the accumulation of materials, effectively avoiding the adhesion of materials to the inner wall of the feed inclined box 104. At the same time, the squeezing of materials by the expansion airbag 46 during expansion is conducive to the feeding of materials, thereby improving the overall functionality and practicality of the equipment.

[0055] When the mixing is finished, because the driving rod 203 drives the rotating disk 501 to rotate clockwise, the inclined surface of the pawl 504 cannot drive the ratchet disk 507 to move, and the pawl 504 is thus retracted into the U-shaped frame 502, and the spiral spring 604 can pull the L-shaped moving rod 602 to retract, and the blocking plate 609 blocks the discharge box 11 to prevent the material from escaping from the discharge box 11 during mixing. When discharging is required, the servo motor 202 drives the driving rod 203 to move counterclockwise, so that the straight surface of the pawl 504 is stuck in the teeth of the ratchet disk 507, and the pawl 504 drives the ratchet disk 507 to rotate counterclockwise, and the ratchet disk 507 drives The annular guide rotating plate 506 moves, and because the L-shaped moving rod 602 is in the reciprocating guide groove 601 on the annular guide rotating plate 506, the L-shaped moving rod 602 moves reciprocatingly in the reciprocating guide groove 601, and the L-shaped moving rod 602 pulls the push plate 603 and the I-shaped slide plate 605 to move, and the I-shaped slide plate 605 drives the guide slot plate 607 to move, and because the guide slot plate 607 guides the slide bar 608, the slide bar 608 drives the blocking plate 609 to reciprocate, thereby intermittently discharging the material to ensure the uniformity of the discharging, and prevent the material from clogging the discharging box 11 too much, affecting the discharging speed;

[0056] When the blocking plate 609 performs reciprocating motion, the blocking plate 609 drives the hinged seat 1 701 to move, and the hinged seat 1 701 drives the pulling plate 702 to move, and the pulling plate 702 thereby pulls the V-shaped pressure plate 704 through the hinged seat 2 703 to perform reciprocating up and down motions, and the V-shaped pressure plate 704 presses down the material falling into the discharge box 11 to prevent excessive accumulation of material affecting the discharge, thereby ensuring smooth discharge, improving the discharge speed, ensuring the subsequent processing quality, and improving the stability of the device. The mixed material enters the annular guide rotating plate 506 through the discharge box 11, and the driving rod 203 drives the spiral feed plate 13 to move counterclockwise, so that the material falling into the discharge pipe 12 can be transported.
