Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly to a crushing ore conveyor for mine engineering. Background Art

[0002] In the field of mine engineering, crushing ore conveying is a key link in the ore mining and processing process, and its efficiency and stability directly affect the mine production benefit. Traditional crushing ore conveyors have many limitations in practical applications. First of all, the conveying length of a single crushing ore conveyor is limited, and it is difficult to meet the crushing ore conveying requirements of large mines with long distances and large scales. If long-distance conveying is to be achieved, intermediate transfer points need to be frequently added, which not only increases the equipment investment cost, but also reduces the crushing ore conveying efficiency due to multiple transfers. Moreover, problems such as crushing ore accumulation and blockage are likely to occur during the transfer process, affecting the overall production progress.

[0003] Secondly, the connection method between traditional crushing ore conveyors is relatively fixed, and the angle between adjacent conveyors is difficult to flexibly adjust according to the actual terrain and production layout. In a complex mine environment, such as an area with large terrain undulations or a compact space layout, conveyors with fixed angles cannot fully adapt to the site conditions, restricting the installation and use of equipment, resulting in difficult conveying path planning and unable to achieve efficient crushing ore conveying.

[0004] In addition, during the process of crushing ore transferring from one conveyor to another, due to the lack of effective guiding measures, the crushing ore is extremely easy to splash out from the inclined section of the conveyor frame to the surrounding areas. This not only causes waste of ore resources, but also increases the difficulty and workload of cleaning work. At the same time, the splashed crushing ore may pose a threat to the safety of surrounding equipment and staff. Moreover, the splashed and accumulated crushing ore around the conveyor will also affect the normal operation of the equipment and increase the probability of equipment failures.

[0005] Therefore, developing a crushing ore conveyor for mine engineering that can flexibly extend the conveying length, freely adjust the connection angle, and effectively avoid crushing ore splashing has become an urgent need to improve mine production efficiency, reduce production costs, and ensure production safety.

A rotating plate is rotatably sleeved on the outer side of the fixed shaft, and a dredging rod is fixedly installed on the outer wall of the rotating plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are: When the ore crusher conveyor for mine engineering of the present invention is in operation, the crushed ore is placed on the conveying chain plate. The driving motor serves as the power core. After starting, it drives the transmission shaft to rotate at a high speed. Through a precise transmission structure, the power is efficiently transmitted to the rotating shaft, and then drives the first transmission gear on the outer side of the rotating shaft to rotate synchronously. The first transmission gear is accurately meshed with the conveying chain plate, and drives the conveying chain plate to continuously rotate at a constant transmission ratio, forming a stable conveying power flow. Driven by this power, the crushed ore can smoothly move forward along the horizontal section of the conveying machine frame and successfully transition to the inclined section. The conveying chain plate is made of high-strength and wear-resistant materials. Even in the face of sharp and hard crushed ore materials, it can maintain stable operation for a long time, effectively resisting the risks of wear and fracture. At the same time, to further improve the conveying stability, the ore crusher conveyor is equipped with a tensioning unit. During the conveying process, the tensioning unit can ensure that the conveying chain plate is closely attached to the transmission gear, avoiding slipping, ensuring the continuity and stability of the conveying operation. This precise tensioning adjustment mechanism effectively extends the service life of the conveying chain plate, reduces the equipment maintenance frequency, and lowers the operation cost.

[0013] Furthermore, multiple ore-crushing conveyors can be connected end to end through specially designed connection units. This connection method is easy to operate and firmly connected. After the connection is completed, the crushed ore discharged from the lower row of the inclined section of the previous conveyor frame can accurately fall onto the horizontal section of the next conveyor frame, realizing seamless connection of the conveying process, thus greatly extending the conveying distance of the crushed ore. In large-scale mining projects, the mining area is vast, and the crushed ore needs to be transported from the mining working face to the ore dressing plant or stockyard over a long distance. By connecting multiple ore-crushing conveyors for use, there is no need to rely on complex transfer equipment and a large number of manual transfers, greatly simplifying the conveying process. At the same time, the modular design of the connection unit makes disassembly and assembly very convenient. According to changes in the mine production layout and conveying requirements, the number of conveyors can be increased or decreased at any time, and the conveying line direction can be adjusted, providing strong support for the flexible scheduling of mine production and significantly improving the adaptability and production efficiency of the mine transportation system.

[0014] In the face of the complex and changeable mine operation environment, the angle adjustment function of this ore-crushing conveyor plays a key role. When adjacent ore-crushing conveyors are connected by a connection unit, their angles can be flexibly adjusted according to actual conveying requirements such as the on-site topography and the layout of the plant space, and the optimal conveying path can be planned. This device adopts a unique angle adjustment structure and a precise positioning system. Even if the angle between the conveyors changes significantly, it can ensure that the crushed ore discharged from the lower row of the inclined section of the conveyor frame accurately falls onto the horizontal section of another group of conveyor frames, significantly improving the environmental adaptability and use flexibility of the equipment.

[0015] The present invention also designs a material guiding unit. The material guiding unit is installed below the inclined section of the conveyor frame and can accurately collect the crushed ore falling from the lower row of the inclined section to prevent it from splashing out. This design not only reduces the waste of ore resources, reduces the cleaning workload, but also eliminates the safety hazards caused by the splashing crushed ore to surrounding equipment and personnel, keeps the operation environment clean and orderly, and further improves the overall use effect and safety production level of the ore-crushing conveyor.

Detailed implementation manners

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] As Figures 1-9As shown in the figure, a crushing conveyor for mine engineering provided by an embodiment of the present invention includes a conveyor frame 101 and a driving motor. The conveyor frame 101 is composed of a horizontal section and an inclined section. A rotating shaft 103 is rotatably installed at the top of the conveyor frame 101, and a first transmission gear 104 is fixedly installed on the outer side of the rotating shaft 103. A conveyor chain plate 105 is drivingly connected to the outer side of the first transmission gear 104. The driving end of the driving motor is rotatably connected to a transmission shaft 107, and the transmission shaft 107 and the rotating shaft 103 are connected by a coupling. Universal wheels 102 are fixedly installed at the bottom of the conveyor frame 101. A plurality of baffle plates 106 are fixedly installed on the outer side of the conveyor chain plate 105 at equal intervals. The baffle plates 106 can be used to block the crushed ore, effectively preventing the crushed ore from rolling down when moving upward along the inclined section of the conveyor frame 101. It further includes: a tensioning unit, which is arranged in the conveyor frame 101, and the conveyor chain plate 105 is sleeved on the outer side of the tensioning unit. The tensioning unit is used to control the tension of the conveyor chain plate 105; a connecting unit, which is arranged outside the conveyor frame 101 and is used to connect the heads and tails of different conveyor frames 101; a material guiding unit, which is arranged above the conveyor frame 101 and is used to receive the crushed ore discharged from above and guide it onto the surface of the conveyor chain plate 105.

[0020] When using the crushing conveyor to convey crushed ore, the crushed ore can be placed on the conveyor chain plate 105. Then, the driving motor drives the transmission shaft 107 to rotate, and the transmission shaft 107 drives the rotating shaft 103 to rotate, so that the first transmission gear 104 on the outer side of the rotating shaft 103 drives the conveyor chain plate 105 to rotate, causing the crushed ore to move along the horizontal section of the conveyor frame 101 towards the inclined section, thereby realizing the conveying operation of the crushed ore. And the tensioning unit can control the tension of the conveyor chain plate 105 to ensure that the conveyor chain plate 105 can stably convey. At the same time, different crushing conveyors can be connected end to end through the connecting unit, so that the crushed ore discharged from the inclined section of the conveyor frame 101 can just fall onto the horizontal section of another set of conveyor frames 101, thereby achieving the purpose of extending the conveying length of the crushed ore. Further, when different crushing conveyors are connected end to end through the connecting unit, the angle between adjacent crushing conveyors can be flexibly adjusted according to the conveying needs. At the same time, no matter how the angle between the crushing conveyors is adjusted, it can ensure that the crushed ore discharged from the inclined section of the conveyor frame 101 can fall onto the horizontal section of another set of conveyor frames 101, making it more flexible to use. Further, with the help of the material guiding unit, the crushed ore discharged from the inclined section of the conveyor frame 101 can also be collected and then stably guided onto the surface of the conveyor chain plate 105, effectively preventing the crushed ore from splashing around during the process of guiding the crushed ore from one set of conveyor frames 101 to another set of conveyor frames 101, and the use effect is better.

[0021] As an embodiment of the present invention, please refer to Figure 8, the tensioning unit includes slide rails 201 fixedly arranged on both sides of the conveying rack 101, and a slider 202 is slidably installed in the slide rails 201. An installation shaft 203 is rotatably connected in the slider 202, and a second transmission gear 204 is fixedly installed on the outer side of the installation shaft 203. The second transmission gear 204 is in transmission connection with the conveying chain plate 105. A hydraulic cylinder 205 is also fixedly installed on the outer side of the conveying rack 101, and the telescopic end of the hydraulic cylinder 205 is connected to the outer wall of the slider 202. When the first transmission gear 104 drives the conveying chain plate 105 to rotate, the second transmission gear 204 will rotate accordingly. The hydraulic cylinder 205 can drive the slider 202 to move in the slide rails 201, which is convenient for adjusting the position of the second transmission gear 204, and further achieves the purpose of controlling the tension of the conveying chain plate 105, so as to ensure that the conveying chain plate 105 can stably convey, and the use is more flexible.

[0022] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 , the connecting unit includes a connecting plate 301 fixedly installed at one end of the conveying rack 101, and an arc inner plate 302 is fixedly installed at the end of the connecting plate 301. A limiting plate 303 is fixedly installed on the outer wall of the arc inner plate 302, and a limiting opening 304 is opened in the limiting plate 303. A support plate 305 is fixedly installed at the other end of the conveying rack 101, and an arc outer plate 306 is fixedly installed at the end of the support plate 305. The arc outer plate 306 and the arc inner plate 302 cooperate with each other. A first installation groove is opened on the upper surface of the arc outer plate 306, and a first telescopic rod 307 is fixedly installed in the first installation groove. A second installation groove is opened on the lower surface of the arc outer plate 306, and a second telescopic rod 308 is fixedly installed in the second installation groove. When the head and tail of different conveying racks 101 are docked, the arc outer plate 306 on one side of a group of conveying racks 101 can be attached to the arc inner plate 302 of another group of conveying racks 101, and the arc inner plate 302 is located between the limiting plates 303. Then, the first telescopic rod 307 and the second telescopic rod 308 can be controlled to expand and contract, so that the telescopic ends of the first telescopic rod 307 and the second telescopic rod 308 are inserted into the limiting opening 304 of the limiting plate 303, which can achieve the purpose of connecting the head and tail of different conveying racks 101. At the same time, the arc outer plate 306 can closely adhere to the arc inner plate 302 and rotate, which is convenient for flexibly adjusting the angle between the conveying racks 101, and the use effect is better.

[0023] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 9, a bracket 401 is also fixedly installed on the outer side of the conveying frame 101, and a side baffle 402 is fixedly installed on the outer wall of the bracket 401. The side baffle 402 is located on both sides of the conveying chain plate 105. Under the blocking action of the side baffle 402, the crushed ore can be prevented from falling from both sides of the conveying frame 101 during conveying, and the use effect is better.

[0024] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7, the material guiding unit includes a vertical plate 501 fixedly arranged on the upper surface of the conveying frame 101, and a blanking hopper 502 is fixedly installed at the top end of the vertical plate 501. An annular plate 504 is rotatably installed on the outer side of the blanking hopper 502, and an annular groove 505 is formed on the inner side of the annular plate 504. A limiting ring 503 is also fixedly installed on the outer wall of the blanking hopper 502, and the limiting ring 503 is located in the annular groove 505. A rotating member 506 is rotatably connected to the upper surface of the annular plate 504, and a material blocking cover 507 is fixedly installed on the outer wall of the rotating member 506. A limiting component is also arranged on the side wall of the material blocking cover 507 for limiting the position of the material blocking cover 507. A dredging component is also arranged below the blanking hopper 502 for promoting the dredging component to dredge the blanking hopper 502 when the conveying chain plate 105 moves. A material blocking hopper 508 is also fixedly installed on the inner wall of the material blocking cover 507. Under the blocking action of the material blocking hopper 508, the crushed ore can completely enter the blanking hopper 502, effectively preventing fine crushed ore from entering the gap between the blanking hopper 502 and the annular plate 504 and causing jamming. When the front and rear ends of different conveying frames 101 are butted, the top end of the conveying frame 101 is just directly above the blanking hopper 502. In this way, when the crushed ore is discharged downward through the top end of the conveying frame 101, it will fall into the blanking hopper 502 of another group of conveyors and be guided to the surface of the conveying chain plate 105 through the blanking hopper 502, effectively realizing the stable transfer of the crushed ore from one group of conveyors to another group of conveyors. At the same time, when the front and rear ends of different conveying frames 101 are butted, the axis of the blanking hopper 502 and the axes of the arc outer plate 306 and the arc inner plate 302 are all kept consistent. In this way, no matter how the angle between the conveying frames 101 is adjusted, it can be ensured that the top end of the conveying frame 101 is always directly above the blanking hopper 502 to ensure the stable transfer of the crushed ore. Further, with the help of the material blocking cover 507, it can also play a certain shielding role, effectively preventing the crushed ore from splashing around when falling, so that the crushed ore fully converges into the blanking hopper 502. The annular plate 504 can rotate on the outside of the blanking hopper 502, which will cause the material blocking cover 507 to rotate together. When the angle between the conveying frames 101 is adjusted, the position of the material blocking cover 507 can be adjusted synchronously so that the top end of the conveying frame 101 is always located in the material blocking cover 507. Still further, during the conveying process of the crushed ore, when a certain group of conveyors needs to be repaired due to damage, the limit on the material blocking cover 507 by the limiting component can be released first, and then the material blocking cover 507 can be flipped to be placed horizontally. At this time, the material blocking cover 507 will not block the conveying frame 101, so that the damaged conveyor can be directly removed from between two adjacent groups of conveyors for repair. At this time, a spare conveyor is replaced for the damaged conveyor, greatly reducing the impact of equipment damage on the conveying of the crushed ore, and the use effect is better.

[0025] As an embodiment of the present invention, please refer to Figure 5 , Figure 6 and Figure 7, the limiting component includes a clamping plate 601 fixedly arranged on the side wall of the material baffle 507. A plug pin 602 is movably installed in the clamping plate 601. A stopper 603 is fixedly installed at the top end of the plug pin 602. A grip 604 is fixedly installed on the outer wall of the plug pin 602. A retaining piece 605 is also fixedly installed on the side wall of the plug pin 602, and the retaining piece 605 is located below the clamping plate 601. A jack is also formed on the outer wall of the ring plate 504, and the plug pin 602 is inserted into the jack. When the plug pin 602 is inserted into the jack, it can play a role in limiting the material baffle 507, effectively preventing the crushed ore from hitting the surface of the material baffle 507 and causing the material baffle 507 to turn over. When it is necessary to release the limit on the material baffle 507, the grip 604 can be held to drive the plug pin 602 to move upward until the retaining piece 605 outside the plug pin 602 contacts the clamping plate 601. At this time, the material baffle 507 can be directly turned over to be placed horizontally, which is very convenient to use.

[0026] As an embodiment of the present invention, please refer to Figure 6 and Figure 7 , the dredging component includes an ear seat 701 fixedly arranged on the lower surface of the feeding hopper 502. A fixed shaft 702 is fixedly installed between the ear seats 701. A rotating plate 703 is rotatably sleeved on the outer side of the fixed shaft 702. A dredging rod 704 is fixedly installed on the outer wall of the rotating plate 703. When the crushed ore is discharged downward through the feeding hopper 502, it occasionally occurs that the crushed ore is too concentrated and blocks the discharge port of the feeding hopper 502. When the conveying chain plate 105 is moving, the baffle 106 on the surface of the conveying chain plate 105 will intermittently contact the rotating plate 703, and as the baffle 106 moves, it will push the rotating plate 703 to rotate around the fixed shaft 702. As a result, the dredging rod 704 on one side of the rotating plate 703 enters the feeding hopper 502, which can play a role in dredging the discharge port of the feeding hopper 502 to ensure smooth discharge of the feeding hopper 502 and better use effect.

[0027] It should be specifically noted that although this specification is described according to the implementation manners, not each implementation manner only includes an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
