Description

Technical Field

[0001] This invention relates to the field of transportation and transfer technology, and in particular to a transportation and transfer device for open-pit waste in metal mines. Background Technology

[0002] A metal mine open-pit waste transport and transfer device is a mechanical equipment specifically used for transporting and transferring waste during the open-pit mining process of metal mines. The main function of this device is to transport waste generated during the mining process (such as waste rock, slag, etc.) from the mine pit to a designated discharge area or treatment facility.

[0003] In practice, some problems still exist:

[0004] Traditional waste transport systems typically employ fixed or simple adjustment mechanisms, failing to flexibly adjust conveyor belt tension based on the type, size, and weight of the waste. Waste varies significantly in weight and volume, especially in open-pit mines where it may include large pieces of ore, gravel, silt, and other materials. These different types of waste require different conveyor belt tensions when passing through. If the conveyor belt tension is not adjusted in a timely manner according to the characteristics of the waste, the following situations may occur:

[0005] An overly loose conveyor belt can cause waste to slide unsteadily during transportation, increasing friction and leading to waste accumulation, stagnation, or jamming of the conveyor belt, thereby reducing transportation efficiency and even causing equipment shutdown.

[0006] An overly tight conveyor belt can easily increase the load on the shaft and transmission components, causing premature wear or failure. At the same time, an overly tight belt can exert excessive pressure on the waste material, which may also change the shape of the waste material and affect subsequent processing.

[0007] The inability to precisely adjust the tension of this type of conveyor belt significantly reduces the stability and long-term reliability of the equipment, while also increasing maintenance costs and downtime during mine operations.

[0008] Furthermore, during waste transportation, waste often splashes or scatters due to friction, impact, and excessive speed. Traditional equipment designs often lack sufficient protective measures in this regard. For example, waste may splash outside the transport equipment, even polluting the surrounding environment and causing a dirty and unsafe work site. Summary of the Invention

[0038] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Please refer to Figures 1 to 7 As shown, a metal mine open-pit waste transportation and transfer device of the present invention includes a support 1, an adjustment and protection mechanism 2 is provided inside the support 1, and a dustproof mechanism 3 is provided on the top of the support 1.

[0040] The adjustment and protection mechanism 2 includes a rotating shaft 208, a conveyor belt 207, a connector 212, an adjustment frame 209, an adjustment rod 210, a guide rail 213, and a slider 211. The connector 212 is rotatably connected to the outer side of the rotating shaft 208, and the slider 211 is fixedly connected to the outer side of the connector 212. The adjustment rod 210 is rotatably connected to the inner side of the slider 211. The adjustment rod 210 is threadedly connected to the outer side of the adjustment frame 209. The guide rail 213 is fixedly connected to the inner side of the adjustment frame 209, and the slider 211 is slidably connected to the outer side of the guide rail 213.

[0041] The dustproof mechanism 3 includes a connecting rod 307, a lead screw 311, a support 313, a connecting plate 312, a transmission pipe 303, a valve 308, and a transmission plate 309. The lead screw 311 is fixedly connected to the middle of the connecting rod 307. The support 313 is threadedly connected to the middle of the lead screw 311. The connecting plate 312 is fixedly connected to one end of the support 313. The transmission plate 310 is fixedly connected to one end of the connecting plate 312. The valve 308 is connected to the bottom end of the transmission pipe 303. The transmission plate 309 is connected to the middle of the valve 308. The bottom end of the transmission plate 309 is in contact with the top end of the transmission plate 310. In actual implementation, the adjustment and protection mechanism 2, through a series of mechanical components such as the rotating shaft 208, conveyor belt 207, connector 212, adjustment frame 209, adjustment rod 210, guide rail 213, and slider 211, can precisely adjust the tension of the conveyor belt 207 and flexibly adjust it according to the different characteristics of the waste material to ensure smooth waste material transportation. The dust prevention mechanism 3, through the precise cooperation of the connecting rod 307, lead screw 311, support 313, connecting plate 312, transmission pipe 303, valve 308, and transmission plate 309, can effectively control the dust generated during waste material transportation, protect the working environment, ensure the health of operators, and avoid pollution problems caused by excessive dust in the mining area. Through the combination of these designs, the working efficiency, stability, and environmental friendliness of the entire waste material transportation device are further improved.

[0042] Optionally, protective frames 201 are fixedly connected to both sides of the top of the support 1, and a first motor 202 is fixedly connected to the outside of the support 1. A roller 205 is fixedly connected to the output end of the first motor 202. In actual implementation, in order to effectively prevent waste from splashing during transportation, protective frames 201 are fixedly connected to both sides of the top of the support 1. The protective frames 201 can not only effectively protect the conveyor belt 207 and prevent waste from scattering due to gravity or high speed, but also form a barrier during transportation to reduce the pollution of the surrounding environment by waste. Especially for harmful waste such as metal slag, the protective frames 201 effectively protect the safety of operators and the surrounding environment of the mining area. The first motor 202 on the outside of the support 1 is responsible for driving the roller 205, which drives the rotation of the conveyor belt 207 to realize the continuous transportation of waste. The first motor 202 can provide stable power output.

[0043] Optionally, the other end of the roller 205 is rotatably connected to a base 206, and the bottom end of the base 206 is fixedly connected to the inner side of the bracket 1. In actual implementation, to ensure the stable operation of the roller 205, the other end of the roller 205 is rotatably connected to the base 206. This design allows the roller 205 to rotate freely on the base 206, while the bottom end of the base 206 is fixedly connected to the inner side of the bracket 1, thus providing a solid support for the roller 205. This effectively prevents the roller 205 from shifting or loosening under high load conditions. At the same time, through the fixed connection, the base 206 can maintain the stability of the entire device, especially when handling heavier waste materials, the base 206 provides sufficient support for the roller 205.

[0044] Optionally, a limiting component 215 is fixedly connected to the top of the support 1, and a connecting frame 204 is fixedly connected to the top of the limiting component 215. A roller 214 is connected to the inner side of the connecting frame 204. In actual implementation, to prevent the conveyor belt 207 from loosening or derailing during waste transportation due to excessive weight or speed of the waste, the limiting component 215 is fixedly connected to the top of the support 1. The limiting component 215 limits the maximum range of motion of the conveyor belt 207, ensuring the stability of the conveyor belt 207 during waste transportation and preventing equipment failure due to movement exceeding the range. The connecting frame 204 provides additional support for the device, ensuring that the waste moves stably along the predetermined track during transportation. The roller 214 is connected to the inner side of the connecting frame 204. The support of the roller 214 further reduces the friction between the conveyor belt 207 and the limiting component 215, ensuring that the waste can pass smoothly without affecting the operation of the equipment due to excessive friction.

[0045] Optionally, one side of the top of the support frame 1 is fixedly connected to the bottom of the adjusting frame 209. A conveyor belt 207 is sleeved between the rotating shaft 208 and the roller 205, with the bottom of the conveyor belt 207 fitting against the top of the roller 214. In actual implementation, the connection between the adjusting frame 209 and the top of the support frame 1 allows the adjusting frame 209 to be adjusted according to the characteristics of different waste materials, adjusting the tension of the conveyor belt 207 to ensure optimal tension and adapt to waste materials of different weights and volumes. The rotating shaft 208 and the roller 205 are connected by the conveyor belt 207, with the bottom of the conveyor belt 207 tightly fitting against the top of the roller 214. The roller 214 provides necessary support for the conveyor belt 207, ensuring that the conveyor belt 207 remains stable during operation and preventing loosening or displacement of the conveyor belt 207 due to uneven load or excessive weight.

[0046] Optionally, a dustproof plate 203 is fixedly connected to the top of the bracket 1. In actual implementation, the design of the dustproof plate 203 ensures that dust will not leak out during waste transportation, providing a healthier and more environmentally friendly working environment for mining operations. It also reduces the cleaning and maintenance costs of the equipment and improves the operating efficiency and safety of the equipment.

[0047] Optionally, a fixing plate 301 is rotatably connected to one end of the connecting rod 307, the bottom end of the fixing plate 301 is fixedly connected to one side of the top of the dustproof plate 203, and a second motor 302 is fixedly connected to the other side of the top of the dustproof plate 203. The output end of the second motor 302 is fixedly connected to the other end of the connecting rod 307.

[0048] Optionally, the bottom end of the support 313 is slidably connected to the top end of the dustproof plate 203, the middle part of the dustproof plate 203 is fixedly connected to the transmission pipe 303, and the bottom end of the valve 308 is fixedly connected to the water storage box 304. In actual implementation, the bottom end of the support 313 is slidably connected to the top end of the dustproof plate 203, allowing the dustproof plate 203 to be adjusted in height or angle according to actual needs to adapt to different working environments. The middle part of the dustproof plate 203 is fixedly connected to the transmission pipe 303, ensuring that the water source can be stably transported to the waste surface through the transmission pipe 303, effectively reducing dust generated during transportation. The valve 308 controls the opening and closing of the water flow, further improving the dustproof effect. The water source is stored in the water storage box 304 and evenly sprayed onto the waste on the conveyor belt 207 through the spraying system, ensuring that dust can be suppressed in a timely manner during waste transportation.

[0049] Optionally, a nozzle 305 is fixedly connected to the bottom of the water storage box 304, and the nozzle 305 is placed at the top of the conveyor belt 207.

[0050] Optionally, a mounting plate 314 is fixedly connected to the outer side of the support 313, a reset spring rod 315 is fixedly connected to the bottom end of the mounting plate 314, the bottom end of the reset spring rod 315 is attached to the top end of the dustproof plate 203, and a pressing block 306 is fixedly connected to the top end of the dustproof plate 203.

[0051] Working Principle: The core components of the device include a support 1, a rotating shaft 208, a conveyor belt 207, a connector 212, an adjusting frame 209, an adjusting rod 210, a guide rail 213, and a slider 211. These components work in conjunction with the adjusting and protective mechanism 2 to precisely adjust the tension of the conveyor belt 207. Specifically, the adjusting rod 210, through a threaded connection with the adjusting frame 209, drives the slider 211 to slide along the guide rail 213. When the slider 211 moves, it causes a change in the position of the rotating shaft 208, thereby adjusting the tension of the conveyor belt 207. This allows for flexible adjustment of the tension of the conveyor belt 207 according to the different properties of the waste, such as weight and volume, ensuring smooth passage of the waste. The adjustment of the rotating shaft 208 directly affects the tension of the conveyor belt 207. The tension of the conveyor belt 207 is adjusted by the interaction of the adjusting rod 210 and the slider 211, which adjusts the position of the rotating shaft 208 to ensure the smooth conveying of waste. The tension of the conveyor belt 207 can be precisely controlled according to the size and weight of the waste to prevent transportation difficulties or equipment damage caused by excessive weight or looseness of the waste. In addition, through the cooperation of the limiting member 215, the connecting frame 204 and the roller 214, the roller 214 provides effective support for the conveyor belt 207 and reduces the wear of the conveyor belt 207. The limiting member 215 and the connecting frame 204 ensure the stability of the conveyor belt 207 during operation and avoid transportation failures caused by excessive weight of waste. Protective frame 201: Protective frames 201 are fixedly connected to both sides of the top of the bracket 1 of the device. It mainly... To prevent waste from splashing into the surrounding environment during high-speed transport, the protective frame 201 effectively controls the scattering range of waste, reducing environmental pollution. The dustproof mechanism 3, including a connecting rod 307, lead screw 311, support 313, connecting plate 312, transmission pipe 303, valve 308, and transmission plate 309, works as follows: the connecting rod 307 connects to the fixed plate 301, and the other end drives the transmission plate 310. The transmission plate 310 controls the opening and closing of the valve 308, thereby regulating the water supply. Through this regulation, the water supply can be accurately delivered to the waste, effectively reducing dust generated during waste transport. The transmission pipe 303 connects to an external water source, and the valve 308 regulates... The size of the water flow is controlled by the transmission plate 309, which, in conjunction with the support 313, ensures uniform water spraying. The second motor 302 drives the connecting rod 307, which in turn drives the lead screw 311 to rotate, controlling the sliding of the support 313. This, in turn, propels the transmission plate 309 to flow in the water pipe. The water source enters the water storage box 304 through the transmission pipe 303 and is then evenly sprayed onto the conveyor belt 207 through the nozzles 305. This intermittent spraying effectively suppresses dust generated during waste transportation, keeping the air fresh. To ensure a long-lasting and stable dustproof effect, the inner side of the dustproof plate 203 needs to be cleaned regularly. For this purpose, the device is specially designed with a return spring rod 315 and a pressing block 306. The return spring rod 315 is connected to the top of the dustproof plate 203.The other end of the return spring rod 315 is periodically compressed by the compression block 306. Each time the spring rod is compressed, it releases its elasticity, causing the dustproof plate 203 to vibrate and remove any waste or dust that may be adhering to the inside of the dustproof plate 203. The coordinated design of the return spring rod 315 and the compression block 306 ensures that the dustproof plate 203 remains clean during operation, preventing waste accumulation from affecting the dustproof effect. The periodic compression of the compression block 306 effectively prevents waste from accumulating on the inside of the dustproof plate 203, ensuring the continuity of the dustproof function.
