Description

Technical Field

[0001] The utility model relates to the technical field of ore mining, in particular to a device for preventing ore blockage and clearing and dredging a high chute. Background Art

[0002] In the mining process of non-coal mines at home and abroad, especially the mining of large mines, due to the large mining volume and frequent transportation, in order to save transportation costs and improve production efficiency, the chute mining method is adopted. A vertical pipeline from top to bottom is drilled in the mine, that is, a chute. The ore reaches the underground transportation channel directly through the chute to achieve the purpose of rapid transportation. The chute mining method has a simple structure, small workload and is easy to master. However, precisely because of the importance of the chute, it is a key link in the entire mining system and the throat of the mine for transporting ore. Once the chute is blocked, the entire production line will be paralyzed, seriously affecting production.

[0003] In the prior art, when the high chute of underground mines is draining tidal ore, powder ore, and mud ore, the chute is often blocked, which seriously affects the production of the mine. Some mines have invented "small rockets" to blast the chute, but because of their poor effect, they have been abandoned. Some mines have also adopted the method of pouring water on the top of the chute and relying on water to penetrate downward to dredge the chute, but the effect is also not ideal. Another method is to use artificial blasting to dredge the chute. Although it can also solve this problem, this method has four disadvantages: 1. Human It is necessary to drill into the blocked chute through the opening of the vibrating ore-discharging machine at the bottom of the shaft, and use tools such as bamboo poles to place explosives. If the ore blocking the shaft falls when placing explosives, people will have nowhere to run, posing a major safety hazard. 2. The explosives cause great damage to the chute structure during the explosion. Over time, the shaft wall, vibrating ore-discharging machine and foundation are all damaged, affecting the ore discharge. 3. The consumption of explosives is large, and sometimes a chute needs to be blasted multiple times to be blown down, which is costly. 4. The effect of blasting the chute is often not ideal, and in most cases it has to be blasted repeatedly.

[0004] At present, there is no ready-made machinery at home and abroad that can effectively solve the problem of chute blockage, and the solutions adopted have obvious shortcomings. At present, most of them rely on manual labor to conduct in-depth observation and operation of the chute. The chute blockage cleaning work mainly relies on people entering the chute to observe and then place explosives for blasting. When workers operate, they are in great danger, inefficient, difficult to place explosives, and inaccurately locate them. At the same time, they are also unable to grasp the real-time status and existing safety hazards in the chute. Many mines have suffered casualties when dealing with chute blockages. Therefore, traditional chute blockage cleaning is very dangerous and endangers the lives of mine workers.

[0005] Therefore, we have made improvements to this and proposed a high chute anti-ore blockage and blockage cleaning and dredging device. Summary of the Invention

The mounting assembly 3 includes a first motor 301, which is fixedly mounted on the front side of the mounting plate 2. A rotating rod 302 is fixedly mounted on the output end of the first motor 301.

A rotating gear 306 is fixedly mounted on the bottom of the support rod 305. The rotating gear 306 is meshed with tooth plates 307 on the front and rear sides. Baffles 308 are fixedly mounted on the opposite sides of the two tooth plates 307. Two plug rods 309 are fixedly mounted on the opposite sides of the two baffles 308. A fixed plate 310 is sleeved on the surface of the first motor 301. The fixed plate 310 is fixedly connected to the mounting plate 2 on the side close to the mounting plate 2.

Both sides of the sliding rod 312 are fixedly mounted on the inner cavity of the mounting plate 2 .

[0041] During the implementation process, the first motor 301 is started. When in use, the first motor 301 drives the rotating rod 302 to rotate. When the rotating rod 302 rotates, the worm 303 is driven to rotate. When the worm 303 rotates, the worm gear 304 is driven to rotate. When the worm gear 304 rotates, the support rod 305 is driven to rotate. When the support rod 305 rotates, the rotating gear 306 is driven to rotate. When the rotating gear 306 rotates, the two tooth plates 307 are driven to move in opposite directions. When the tooth plate 307 moves, the baffle 308 is driven to move. When the baffle 308 moves, the insertion rod 309 is driven to move. The rod 309 moves to the groove on the limit plate 5, so that the limit plate 5 can be quickly installed. When the limit plate 5 needs to be disassembled, the first motor 301 is started again to disengage the insertion rod 309 from the inside of the limit plate 5, so as to disassemble the limit plate 5. The connecting plate 4 is installed on the limit plate 5 and will be installed and disassembled along with the limit plate 5. The protective shell 6, the drive assembly 7, the first fixing frame 8 and the first pulley 9 are all installed on the connecting plate 4 and will be installed and disassembled along with the connecting plate 4, which is more convenient when the device needs to be maintained or replaced. Example

[0042] The drive assembly 7 includes a second motor 701, which is fixedly mounted on the front side of the protective shell 6. A transmission rod 702 is fixedly mounted on the output end of the second motor 701. Two first sprockets 703 are fixedly mounted on the surface of the transmission rod 702. A chain 704 is engaged with the surface of the first sprocket 703. A second sprocket 705 is engaged with one side of the inner cavity of the chain 704. A connecting rod 706 is fixedly mounted in the inner cavity of the second sprocket 705. The front and rear sides of the surface of the connecting rod 706 are respectively fixedly connected to the inner cavities of the two first pulleys 9. The side of the connecting rod 706 near the first fixed frame 8 is movably connected to the first fixed frame 8. A stabilizing plate 707 is sleeved on the surface of the second motor 701. The side of the stabilizing plate 707 near the protective shell 6 is fixedly connected to the protective shell 6.

[0043] During the implementation process, when the high chute wellhead 10 is not blocked, the ore falls through the grid screen 11, and part of the ore collides with the wire rope 12 in the wellbore, disrupting the movement trajectory of the ore. Tide ore, powder ore, and mud ore will be scattered everywhere, and the blockage situation will be greatly reduced, which can effectively prevent the occurrence of ore blockage. When the high chute wellhead 10 is blocked by ore, the fixed clamp 14 is released and the second motor 701 is started. When in use, the second motor 701 drives the transmission rod 702 to rotate, and the transmission rod 702 rotates to drive the two first sprockets 703 to rotate. The first sprocket 703 rotates and drives the second sprocket 705 to rotate through the chain 704. The two second sprockets 705 rotate to drive the two connecting rods 706 to rotate. The two connecting rods 706 rotate to drive the four first pulleys 9 to rotate. The rotation of the first pulley 9 drives the wire rope 12 to move vertically up and down. In this case, the wire rope 12 that passes around the first pulley 9 and the second pulley 19 is passed through the high chute wellhead 10 and extended to the bottom of the high chute wellhead 10. In this way, in the process of shoveling ore into the high chute wellhead 10, the rotation of the second motor 701 drives the wire rope 12 to move vertically up and down, and the ore collides and rubs against the wire rope 12, which will also cause shaking and vibration. In this way, by lifting or lowering the wire rope 12 back and forth, the ores rub against each other, move, loosen, and continuously produce gaps and collapse downward, which effectively reduces the accumulation of wet ore and powder ore in the high chute wellhead 10, prevents the occurrence of blockage problems at the high chute wellhead 10, and efficiently dredges the blockage of the high chute wellhead 10, thereby achieving the purpose of dredging the high chute wellhead 10.

[0044] When in use, by starting the first motor 301, the first motor 301 drives the rotating rod 302 to rotate when in use, and the rotating rod 302 drives the worm 303 to rotate when the rotating rod 302 rotates, and the worm 303 drives the worm gear 304 to rotate when the worm gear 304 rotates, and the support rod 305 drives the rotating gear 306 to rotate when the support rod 305 rotates, and the rotating gear 306 drives the two tooth plates 307 to move in opposite directions when the tooth plate 307 moves, and the baffle 308 moves when the baffle 308 moves, and the insertion rod 309 moves, and the insertion rod 309 is moved into the groove on the limit plate 5, so that the limit plate 5 can be quickly installed. When the positioning plate 5 is disassembled, the first motor 301 is started again to disengage the insertion rod 309 from the inside of the limiting plate 5, thereby disassembling the limiting plate 5. The connecting plate 4 is installed on the limiting plate 5 and will be installed and disassembled along with the limiting plate 5. The protective shell 6, the driving assembly 7, the first fixing frame 8 and the first pulley 9 are all installed on the connecting plate 4 and will be installed and disassembled along with the connecting plate 4. It is more convenient when the device needs to be maintained or replaced. When the high chute wellhead 10 is not blocked, the ore falls through the grid screen 11, and part of the ore collides with the wire rope 12 in the wellbore. The movement trajectory of the ore is disrupted, and the wet ore, powder ore and mud ore will be scattered everywhere, and the blockage will be The situation of ore blockage is greatly reduced, and the situation of ore blockage can be effectively prevented. When the high chute wellhead 10 is blocked by ore, the fixed clamp 14 is loosened and the second motor 701 is started. The second motor 701 drives the transmission rod 702 to rotate when in use. The transmission rod 702 rotates to drive the two first sprockets 703 to rotate. The first sprocket 703 rotates to drive the second sprocket 705 to rotate through the chain 704. The two second sprockets 705 rotate to drive the two connecting rods 706 to rotate. The two connecting rods 706 rotate to drive the four first pulleys 9 to rotate. The first pulley 9 rotates to drive the wire rope 12 to move vertically up and down. In this case, by bypassing the first pulley 9 The steel wire rope 12 of the second pulley 19 passes through the high chute wellhead 10 and extends to the bottom of the high chute wellhead 10. In this way, in the process of shoveling ore into the high chute wellhead 10, the rotation of the second motor 701 drives the steel wire rope 12 to move vertically up and down, and the ore collides and rubs against the steel wire rope 12, which will also cause shaking and vibration. In this way, by lifting or lowering the steel wire rope 12 back and forth, the ores rub against each other, move, loosen, and continuously produce gaps and collapse downward, which effectively reduces the accumulation of wet ore and powder ore in the high chute wellhead 10, prevents the occurrence of blockage problems at the high chute wellhead 10, and efficiently dredges the blockage of the high chute wellhead 10, thereby achieving the purpose of dredging the high chute wellhead 10.

Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
