Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, specifically to an automatic unloading device for copper concentrate. Background Technology

[0002] Copper concentrate is a raw material obtained from copper-bearing ore through flotation with a copper content (mass fraction) of not less than 13% for copper smelting. It can be directly supplied to smelters for copper smelting. During the production and processing of copper concentrate, it is necessary to transport the copper concentrate, and the transportation process requires unloading the raw material.

[0003] The existing equipment has the following disadvantages: During the process of transporting ore to the conveyor belt, the impact of the ore on the belt conveyor can easily cause the ore to splash randomly. In addition, there is a certain height difference between the ore feeding device and the mining belt conveyor, which causes the ore to accelerate and impact the surface of the belt conveyor, which can easily damage the conveyor belt and frame. Furthermore, it can cause the material to stick to the conveyor, affecting the conveying efficiency of the conveyor.

[0004] Therefore, this application proposes an automatic copper concentrate unloading device to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic unloading device for copper concentrate to solve the problems mentioned above, which easily cause random splashing of ore and the accelerated impact of ore on the surface of the belt conveyor, which can easily damage the conveyor belt and frame.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic copper concentrate unloading device, comprising a conveyor for transporting copper concentrate, and further comprising:

[0007] A buffer unit is installed on one side of the conveyor feed inlet to buffer the falling copper concentrate material;

[0008] A support unit is disposed on the conveyor below the buffer unit, and is used to support the materials transported on the conveyor.

[0009] A cleaning unit is located on the side of the conveyor away from the buffer unit, and is used to clean impurities on the conveyor.

[0010] The conveyor includes a support frame, a motor fixedly mounted on the support frame, a rotating shaft mounted on the power output end of the motor and passing through the support frame, a transmission roller fixedly mounted on the rotating shaft, and a conveyor belt mounted on the transmission roller and located inside the support frame. The motor and the rotating shaft are connected by a coupling.

[0011] The upper end of the bracket is provided with first trough-shaped idlers for supporting the conveyor belt at intervals;

[0012] The lower end of the support is provided with guide rollers for guiding the conveyor belt.

[0013] The buffer unit includes fixed side plates symmetrically fixed to the support, a hopper for storing copper concentrate material fixed inside the fixed side plates, a buffer device disposed inside the hopper for buffering the impact force of the falling copper concentrate, a material control device disposed inside the hopper and located on one side of the material discharge port of the buffer device for controlling the amount of copper concentrate discharged, and a material guide device disposed inside the hopper and located below the material control device for guiding the copper concentrate. The material control device is connected to the rotating shaft through a first transmission component.

[0014] The buffer device includes a connecting rod fixed to the inner wall of the silo, a buffer plate rotatably sleeved on the connecting rod and inclined, a base plate fixed to the lower end of the buffer plate, and an elastic element inclined between the base plate and the inner wall of the silo.

[0015] The buffer plate is positioned above the material control device and is equipped with chains at intervals for clearing the copper concentrate.

[0016] The material control device includes a feeding plate for concentrating copper concentrate, which is fixed inside the silo and located at the feed inlet of the buffer plate; a connecting shaft passing through the silo; and a spiral blade fixed at the position of the connecting shaft inside the silo. The spiral blade abuts against the silo and the feeding plate.

[0017] A limiting block is fitted in the middle of the connecting shaft, and the spiral blades are symmetrically arranged about the limiting block.

[0018] The first transmission component includes a first driving wheel fixed on the rotating shaft, a first driven wheel fixed on the connecting shaft, and a first belt for transmission sleeved between the first driving wheel and the first driven wheel.

[0019] The material guiding device includes a material guiding plate fixed inside the hopper and located below the material feeding plate and inclined thereon, a triangular limiting block fixed at the upper end of the material guiding plate, and a material pouring side plate fixed at the lower end of the hopper and inclined toward the middle of the conveyor belt. A material feeding trough is provided between the material guiding plate and the material pouring side plate.

[0020] The support unit includes a second trough-shaped roller fixed at a distance from the upper end of the bracket and a buffer pad sleeved on the second trough-shaped roller. The second trough-shaped roller is located below the pouring side plate.

[0021] The cushioning pad abuts against the conveyor belt.

[0022] The cleaning unit includes a fixed base fixed to one side of the bracket, a cleaning rod rotatably passing through the fixed base, a cleaning roller fixedly sleeved on the cleaning rod and located inside the fixed base, a cleaning brush fixedly mounted on the cleaning roller, and a second transmission component for transmitting kinetic energy disposed between the cleaning rod and the rotating shaft, wherein the cleaning brush abuts against the conveyor belt.

[0023] The second transmission component includes a second driving wheel fixed on the rotating shaft, a second driven wheel fixed on the cleaning rod, and a second belt for transmission sleeved between the second driving wheel and the second driven wheel.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] In this invention, when transporting copper concentrate, the copper concentrate is buffered by a buffer unit before falling onto a conveyor. A support unit on the conveyor supports the material falling onto it. When the copper concentrate falls into the hopper, it impacts the buffer plate, causing the buffer plate to rotate along the connecting rod. During the downward swing of the buffer plate, the bottom plate compresses the elastic element, which provides elastic support to the buffer plate, facilitating its return motion. During the up-and-down swing of the buffer plate, the side away from the connecting rod drives the chain to swing, which clears material accumulated above the material control device, reducing [material buildup]. To minimize material accumulation, the guide plate is angled downwards and curved towards the discharge side plate. This allows material falling from the discharge plate to be transported along the guide plate towards the discharge side plate, thus dispersing the copper concentrate during transport. This reduces material accumulation and the distance difference between the copper concentrate falling onto the conveyor belt, thereby reducing the impact force of the copper concentrate on the conveyor belt and minimizing damage to the conveyor. Furthermore, it restrains the falling material, reducing splashing. The cleaning unit cleans the conveyor during transport, reducing material adhesion and improving conveying efficiency.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-10The present invention provides a technical solution: an automatic unloading device for copper concentrate, comprising a conveyor 1 for transporting copper concentrate, and further comprising:

[0039] Buffer unit 2 is located on one side of the feed inlet of conveyor 1 and is used to buffer the falling copper concentrate material;

[0040] Support unit 3 is located below buffer unit 2 on conveyor 1 and is used to support the materials transported on conveyor 1.

[0041] The cleaning unit 4 is located on the side of the conveyor 1 away from the buffer unit 2, and is used to clean impurities on the conveyor 1.

[0042] It should be noted that during operation, when transporting copper concentrate, the copper concentrate is buffered by buffer unit 2 before falling onto conveyor 1. Support unit 3 on conveyor 1 can support the material falling onto conveyor 1. Under the action of buffer unit 2, the copper concentrate material falls slowly onto conveyor 1, reducing the impact force of the material on conveyor 1 and restricting the falling material to reduce material splashing. Cleaning unit 4 can clean conveyor 1 during transportation, which can reduce the material adhering to conveyor 1 and affecting the conveying efficiency of conveyor 1.

[0043] In one embodiment, the conveyor 1 includes a support 11, a motor 12 fixedly mounted on the support 11, a rotating shaft 14 mounted on the power output end of the motor 12 and passing through the support 11, a transmission roller 15 fixedly sleeved on the rotating shaft 14, and a conveyor belt 16 sleeved on the transmission roller 15 and located inside the support 11. The motor 12 and the rotating shaft 14 are connected by a coupling 13.

[0044] The upper end of the support frame 11 is provided with first trough-shaped idlers 17 for supporting the conveyor belt 16 at intervals;

[0045] The lower end of the support frame 11 is provided with guide rollers 18 for guiding the conveyor belt 16.

[0046] With this design, the starting motor 12 drives the rotating shaft 14 to rotate under the action of the coupling 13, which in turn drives the transmission roller 15 fixed on the rotating shaft 14 to rotate. The transmission roller 15 drives the conveyor belt 16 to rotate and transport the copper concentrate. The first trough-shaped idler roller 17 can make the conveyor belt 16 arc-shaped, reducing the leakage of copper concentrate during transportation. The guide roller 18 can guide the transmission conveyor belt 16, so that the conveyor belt 16 is always in a taut state, improving the conveying efficiency of the conveyor belt 16.

[0047] In one embodiment, the buffer unit 2 includes a fixed side plate 27 symmetrically fixed on the support 11, a hopper 21 for storing copper concentrate material fixed inside the fixed side plate 27, a buffer device 23 disposed inside the hopper 21 for buffering the impact force of the falling copper concentrate, a material control device 24 disposed inside the hopper 21 and located on the side of the discharge port of the buffer device 23 for controlling the amount of copper concentrate discharged, and a material guide device 25 disposed inside the hopper 21 and located below the material control device 24 for guiding the copper concentrate. The material control device 24 is connected to the rotating shaft 14 through the first transmission member 22.

[0048] With this design, copper concentrate falls from above into the hopper 21. As the material falls, it comes into contact with the buffer device 23, which can buffer the impact force of the falling copper concentrate. Then, the copper concentrate falls through the discharge port of the buffer device 23 into the control device 24. The control device 24 rotates under the drive of the first transmission component 22, which can evenly and slowly feed the material onto the guide device 25. Then, guided by the guide device 25, the material falls onto the conveyor belt 16. When the material falls onto the conveyor belt 16, the support unit 3 at the lower end of the conveyor belt 16 can support the material and further buffer the impact force of the material.

[0049] In one embodiment, the buffer device 23 includes a connecting rod 232 fixed to the inner wall of the hopper 21, a buffer plate 231 rotatably sleeved on the connecting rod 232 and inclined, a bottom plate 2311 fixed to the lower end of the buffer plate 231, and an elastic element 233 inclined between the bottom plate 2311 and the inner wall of the hopper 21. The elastic element 233 is made of a spring or an elastic pad.

[0050] The buffer plate 231 is located above the material control device 24 and is equipped with chains 234 at intervals for clearing the copper concentrate.

[0051] With this design, when copper concentrate falls into the hopper 21, it impacts the buffer plate 231, causing the buffer plate 231 to rotate along the connecting rod 232. During the downward swing of the buffer plate 231, the bottom plate 2311 squeezes the elastic element 233, and the elastic element 233 provides elastic support for the buffer plate 231, which can easily drive the buffer plate 231 to perform a reset movement. During the up-and-down swing of the buffer plate 231, the side away from the connecting rod 232 drives the chain 234 to swing. The chain 234 can clear the material accumulated above the material control device 24, which can reduce the phenomenon of material accumulation.

[0052] In one embodiment, the material control device 24 includes a feeding plate 244 for concentrating copper concentrate, which is fixed inside the silo 21 and located at the feeding port of the buffer plate 231; a connecting shaft 241 passing through the silo 21; and a spiral blade 243 fixed to the connecting shaft 241 at the position inside the silo 21. The spiral blade 243 abuts against the silo 21 and the feeding plate 244.

[0053] A limiting block 242 is sleeved in the middle of the connecting shaft 241, and the spiral blades 243 are symmetrically arranged about the limiting block 242.

[0054] With this design, the rotating shaft 14 drives the connecting shaft 241 to rotate through the first transmission component 22 during rotation. The connecting shaft 241 can drive the spiral blades 243 to rotate. During the rotation of the spiral blades 243, the material inside the feed plate 244 falls evenly onto the guiding device 25. The spiral blades 243 are symmetrically arranged about the limiting block 242, which can transport the copper concentrate to the side away from the limiting block 242 during the falling process, thereby improving the conveying efficiency of the falling copper concentrate.

[0055] In one embodiment, the first transmission member 22 includes a first driving wheel 221 fixed on the rotating shaft 14, a first driven wheel 223 fixed on the connecting shaft 241, and a first belt 222 for transmission sleeved between the first driving wheel 221 and the first driven wheel 223.

[0056] With this design, the rotating shaft 14 drives the first driving wheel 221 to rotate, which in turn drives the first driven wheel 223 to rotate via the first belt 222. The first driven wheel 223 then drives the connecting shaft 241 to rotate. This allows the same motor 12 to drive multiple devices for transportation, improving equipment efficiency and reducing energy consumption.

[0057] In one embodiment, the material guiding device 25 includes a guide plate 251 fixed inside the hopper 21 at a position below the discharge plate 244 and inclined thereon, a triangular limiting block 252 fixed at the upper end of the guide plate 251, and a discharge side plate 26 fixed at the lower end of the hopper 21 and inclined toward the middle of the conveyor belt 16. A discharge trough 253 is provided between the guide plate 251 and the discharge side plate 26.

[0058] With this design, the guide plate 251 is inclined downward and arc-shaped towards the side of the discharge plate 26, so that the material falling from the discharge plate 244 is transported towards the side of the discharge plate 26 along the guide plate 251 as it falls. This can disperse the transport of copper concentrate, reduce material accumulation, and reduce the distance difference between the copper concentrate falling onto the conveyor belt 16, thereby reducing the impact force of the copper concentrate on the conveyor belt 16.

[0059] In one embodiment, the support unit 3 includes a second grooved roller 31 fixed at a distance from the upper end of the bracket 11 and a buffer pad 32 sleeved on the second grooved roller 31. The second grooved roller 31 is located below the pouring side plate 26.

[0060] The cushioning pad 32 abuts against the conveyor belt 16.

[0061] With this design, the buffer pad 32 can further absorb the impact force of the copper concentrate on the conveyor belt 16, thereby further reducing the damage of the copper concentrate to the conveyor belt 16 and increasing the service life of the conveyor belt 16.

[0062] In one embodiment, the cleaning unit 4 includes a fixed base 41 fixed to one side of the bracket 11, a cleaning rod 42 rotatably passing through the fixed base 41, a cleaning roller 44 fixedly sleeved on the cleaning rod 42 and located inside the fixed base 41, a cleaning brush 45 fixedly disposed on the cleaning roller 44, and a second transmission member 43 disposed between the cleaning rod 42 and the rotating shaft 14 for transmitting kinetic energy. The cleaning brush 45 abuts against the conveyor belt 16, and a scraper 46 for scraping the conveyor belt 16 is fixedly disposed at the lower end of the bracket 11.

[0063] With this design, during the rotation of the rotating shaft 14, the cleaning rod 42 is driven to rotate through the second transmission component 43, which in turn causes the cleaning roller 44 to drive the cleaning brush 45 to rotate. The cleaning brush 45 rubs against the conveyor belt 16 to clean the copper concentrate material adhering to the conveyor belt 16. After the initial cleaning, the conveyor belt 16 moves to the scraper 46 and is cleaned again by the scraper 46, making the conveyor belt 16 even cleaner and improving the conveying efficiency of the conveyor belt 16.

[0064] In one embodiment, the second transmission member 43 includes a second driving wheel 431 fixed on the rotating shaft 14, a second driven wheel 433 fixed on the cleaning rod 42, and a second belt 432 for transmission sleeved between the second driving wheel 431 and the second driven wheel 433.

[0065] With this design, the transmission method is the same as that of the first transmission component 22, which can save energy.

[0066] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
