Description

Technical Field

[0001] This utility model belongs to the field of raw material mixing technology, and in particular relates to an efficient mixing and stirring device for raw materials used in mine backfilling. Background Technology

[0002] Backfilling mining has advantages such as low loss rate, low dilution rate, and high safety, and it is also a mining method that can effectively control mine ground pressure activity. With the increasing development of backfilling mining technology, especially cemented backfilling mining technology, many complex technical problems in mines have been well solved. It has played a significant role in deep mining, surface protection, "mining rich mines while protecting poor mines", "mining underground", reducing dilution and loss rates, preventing internal fires, mitigating rock bursts, and effectively controlling ground pressure activity.

At the same time, the efficiency is very poor when used directly after mixing, and some material will remain inside when discharging the material, which will also lead to waste. Therefore, we propose an efficient mixing and stirring device for raw materials used in mine backfilling. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The mixing mechanism includes an L-plate, which is fixedly connected to the top of the mixing box. A motor is fixedly connected to the outer wall of the L-plate. A rotating shaft is fixedly connected to the bottom output end of the motor via a coupling. Several mixing plates are fixedly connected to the outer wall of the rotating shaft. A fixed rod is fixedly connected to the outer wall of each mixing plate. A rotating plate is slidably connected to the outer wall of the fixed rod.

A mixing blade is rotatably connected to the outer wall of the fixed shaft. A screening mechanism is provided on the outer wall of the rotating shaft.

[0008] Furthermore, the screening mechanism includes a pulley, which is fixedly connected to a rotating shaft. A belt is driven to the outer wall of the pulley, and a second pulley is driven to the inner wall of the belt. A worm gear is fixedly connected to the inner wall of the second pulley, and a fixing block is fixedly connected to the outer wall of the mixing box. The fixing block is rotatably connected to the worm gear.

[0009] Furthermore, a handle is fixedly connected to the outer wall of the baffle, a scraper is fixedly connected to the inner wall of the mixing box, the scraper is in contact with the outer wall of the baffle, and a discharge pipe is fixedly connected to the top inner wall of the mixing box.

[0010] Furthermore, a rotating rod is rotatably connected to the inner wall of the mixing box, a turbine is fixedly connected to the outer wall of the rotating rod, the turbine meshes with a worm gear, a top plate is fixedly connected to the outer wall of the rotating rod, and several moving slots are provided on the inner wall of the mixing box.

[0012] Furthermore, the inner wall of the mixing tank is provided with a cleaning mechanism, which includes a moving rod. The inner wall of the mixing tank is provided with a U-shaped groove, and the moving rod is slidably connected to the U-shaped groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model incorporates an L-plate on the mixing chamber. When the equipment is needed, the materials to be mixed are added to the mixing chamber through the feeding pipe and then fall onto the baffle. The motor is then started, driving the rotating shaft to rotate, which in turn drives multiple mixing plates to move. As the mixing plates move, multiple fixed rods rotate around the rotating shaft. During this rotation, the rotating plates begin to sway slightly or rotate due to centrifugal force. The movement of the rotating plates also causes multiple connecting blocks to move along with the fixed shaft, resulting in a more thorough mixing of the internal materials. Furthermore, the centrifugal force and friction between the materials enhance the mixing effect, reducing unnecessary power waste and minimizing material waste during subsequent processing.

[0016] 2. This utility model incorporates a turbine on a worm gear. During operation, the material falls onto the sieve plate. Simultaneously, the rotating shaft drives a pulley, which in turn drives the worm gear, causing the turbine to rotate. The rotating rod's rotation continuously lifts the sieve plate from the top plate. As the sieve plate moves, multiple sliders slide within the moving groove, compressing multiple springs. Once the top plate is no longer in contact with the sieve plate, the sliders quickly return to their original position, allowing the sieve plate to rapidly sieve the internal material. This enables sieving after mixing, reducing subsequent processing time. The sieved material also performs better in use and prevents waste caused by residual material during discharge.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] Please see Figure 1-5 As shown, this utility model is a high-efficiency mixing and stirring device for raw materials used in mine backfilling, including a mixing box 1.

When the motor 202 starts, it drives the rotating shaft 203 to rotate, which in turn drives multiple mixing plates 209 to move and mix the internal materials. The bottom output end of the motor 202 is fixedly connected to the rotating shaft 203 via a coupling. Several mixing plates 209 are fixedly connected to the outer wall of the rotating shaft 203. A fixing rod 204 is fixedly connected to the outer wall of the mixing plates 209. A rotating... When the fixed rod 204 rotates, the rotating plate 205 will be driven to rotate due to the centrifugal force generated.

A mixing blade 208 is rotatably connected to the outer wall of the fixed shaft 207. When the rotating plate 205 rotates, the multiple connecting blocks 206 will drive the fixed shaft 207 to rotate. At the same time, the internal material friction will drive the mixing blade 208 to strengthen the mixing of the internal material. A screening mechanism 3 is provided on the outer wall of the rotating shaft 203.

[0029] The screening mechanism 3 includes a pulley 301, which is fixedly connected to the rotating shaft 203. A belt 302 is driven to the outer wall of the pulley 301, and a second pulley 303 is driven to the inner wall of the belt 302. When the rotating shaft 203 rotates, it will drive the pulley 301 to move. A worm gear 304 is fixedly connected to the inner wall of the second pulley 303. A fixing block 305 is fixedly connected to the outer wall of the mixing box 1. The fixing block 305 is rotatably connected to the worm gear 304. A handle 107 is fixedly connected to the outer wall of the baffle 106. A scraper 108 is fixedly connected to the inner wall of the mixing box 1.

The scraper 108 is attached to the outer wall of the baffle 106. A feed pipe 109 is fixedly connected to the top inner wall of the mixing box 1.

[0030] A rotating rod 306 is rotatably connected to the inner wall of the mixing box 1. A turbine 307 is fixedly connected to the outer wall of the rotating rod 306. The turbine 307 meshes with a worm gear 304. When the worm gear 304 rotates, it will drive the turbine 307 to move, thereby driving the rotating rod 306 to rotate. A top plate 308 is fixedly connected to the outer wall of the rotating rod 306. Several moving grooves 310 are opened on the inner wall of the mixing box 1. A second slider 311 is slidably connected to the inner wall of the moving groove 310. A sieve plate 309 is fixedly connected to the outer wall of the second slider 311. When the rotating rod 306 rotates, it will drive the top plate 308 to continuously lift the sieve plate 309 and drive the second slider 311 to move. Several springs 312 are fixedly connected to the outer wall of the second slider 311. The springs 312 are fixedly connected to the moving grooves 310.

[0031] The inner wall of the mixing box 1 is provided with a cleaning mechanism 4, which includes a moving rod 402. The inner wall of the mixing box 1 is provided with a U-shaped groove 401. The moving rod 402 is slidably connected to the U-shaped groove 401. The outer wall of the moving rod 402 is fixedly connected with a scraper 403. When the moving rod 402 is moved, it will slide in the U-shaped groove 401, and at the same time drive the scraper 403 to clean the bottom of the equipment. The scraper 403 is in contact with the inner wall of the mixing box 1. The outer wall of the moving rod 402 is fixedly connected with a handle 404. The bottom inner wall of the mixing box 1 is fixedly connected with a discharge box 405.

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed, the materials to be mixed are added to the mixing box 1 through the feed pipe 109, and then fall onto the baffle 106. The motor 202 is then started, which drives the rotating shaft 203 to rotate, thereby causing multiple mixing plates 209 to move. As the mixing plates 209 move, they cause multiple fixed rods 204 to rotate around the rotating shaft 203. During this rotation, multiple rotating plates 205 may begin to sway slightly or rotate due to centrifugal force. 5. During movement, multiple connecting blocks 206 will drive the fixed shaft 207 to move together. Simultaneously, the friction between the connecting blocks and the internal material will cause the mixing blades 208 to further mix the material. After the internal material is fully mixed, pulling the handle 107 will cause the baffle 106 to move. As the baffle 106 moves, multiple sliders 105 will slide within the second groove 104. Then, as it is gradually pulled outwards, the internal scraper 108 will scrape the top surface of the baffle 106, removing material from its surface to prevent... Waste occurs when material falls onto the sieve plate 309. Simultaneously, the rotating shaft 203 rotates, driving pulley 301, which in turn drives belt 302 to pulley 303. This movement, in turn, drives worm gear 304, which in turn drives turbine 307 to rotate rod 306. As rod 306 rotates, top plate 308 continuously lifts sieve plate 309. As sieve plate 309 moves, multiple sliders 311 slide within moving grooves 310, simultaneously compressing multiple springs 312. The material then stops contacting sieve plate 309 with top plate 308. After 09, the slider 311 will quickly reset, allowing the sieve plate 309 to quickly perform a simple sieve on the internal material, reducing the time required for subsequent processing. After sieving, the discharge box 405 is opened to discharge the material. After discharge, multiple handles 404 are pulled to move the moving rod 402. When the moving rod 402 moves, it will simultaneously drive the scraper 403 to clean the bottom inner wall of the mixing box 1, quickly discharging the residual material and preventing it from sticking to the equipment and causing waste.
