Description

Technical Field

[0001] This utility model relates to the field of ore conveying technology, and in particular to a mining ore conveying equipment. Background Technology

[0002] Mines include coal mines, metal mines, non-metal mines, building material mines, and chemical mines, etc. The scale of a mine (also known as production capacity) is usually expressed in terms of annual output or daily output. In the mining production process, the mining operation is the production link that consumes the most manpower, material resources, and capital, but it also has the greatest potential to reduce mining costs. The main ways to reduce mining costs are to improve labor productivity and product quality, reduce material consumption, and use conveying equipment to transport ore.

[0003] In the prior art, such as Chinese Patent No. CN221115482U, an improved mining ore conveying equipment is disclosed, including two conveyor belts and a cleaning box. The cleaning box is set between the two conveyor belts. Conveyor rollers are evenly arranged inside the cleaning box. Threaded rods are movably installed on both sides of the top of the cleaning box. A first connecting rod and a second connecting rod are respectively threaded onto the outer sides of the two threaded rods. Diverter pipes are fixed to the bottom ends of the first and second connecting rods. Spray nozzles are evenly installed at the bottom ends of the diverter pipes. When the ore passes through the cleaning box, it is transported by the conveyor rollers inside the cleaning box. There is a certain gap between the conveyor rollers to facilitate the falling of stones and particulate impurities in the ore into the bottom of the cleaning box for removal. At the same time, the two diverter pipes on the upper inner side of the cleaning box reciprocate, and the spray nozzles at the bottom ends of the diverter pipes spray water, thereby washing the ore and cleaning the mud on the surface of the ore.

[0004] While the above-mentioned solution has the advantages mentioned above, it also has disadvantages. Although a cleaning box can be set between the two conveyor belts, and the ore is transported by the conveyor rollers inside the cleaning box with certain gaps between them to allow stones and particulate impurities in the ore to fall to the bottom of the cleaning box and be removed, the ore is usually irregularly shaped. When the ore is conveyed by the conveyor rollers, there is a possibility that the ore may get stuck between the two conveyor rollers. This stuck ore may obstruct the subsequent conveying of ore, causing ore accumulation, which may damage the conveying equipment and reduce its service life. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, although a cleaning box can be set between two conveyor belts, and the ore is transported by the conveyor rollers inside the cleaning box with certain gaps between the rollers to facilitate the falling of stones and particulate impurities in the ore to the bottom of the cleaning box for removal, the ore is usually irregular in shape. When the ore is conveyed by the conveyor rollers, there may be situations where the ore gets stuck between the two conveyor rollers. This stuck ore will obstruct the subsequent conveying of ore, causing ore accumulation, which may damage the conveying equipment and reduce its service life.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a mining ore conveying device, comprising: two conveyor belts and a cleaning box, wherein the cleaning box is disposed between the two conveyor belts, and further comprising:

[0007] Multiple conveying rollers are equidistantly rotatably connected to opposite sides of the inner wall of the cleaning box. Multiple sprockets are provided on one side of the cleaning box, with two sprockets fixedly connected to two of the conveying rollers, and the remaining sprockets fixedly connected in pairs to the remaining conveying rollers. Chains mesh between adjacent outer surfaces of the sprockets along different axes. A motor is fixedly connected to one side of the cleaning box, with one end of the motor fixedly connected to one end of a conveying roller. Discs are fixedly connected to both ends of the other two conveying rollers, and round rods are fixedly connected to the eccentric parts of the discs. Multiple sliding grooves are equidistantly formed on opposite sides of the cleaning box, with slide bars slidably connected inside the two sliding grooves. A pusher frame is fixedly connected to the top of each slide bar. Movable frames are fixedly connected to opposite sides of the slide bars, with straight slots formed on the side of the movable frames near the top. The outer surfaces of the two round rods are slidably connected inside the straight slots.

[0008] Preferably, the top of the cleaning box is symmetrically and fixedly connected to two conveying pipes, one end of each conveying pipe is fixedly connected to a guide pipe, and multiple nozzles are fixedly connected at equal intervals on the outer surface of the guide pipe. The conveying pipes, guide pipes, and multiple nozzles are interconnected.

[0009] Preferably, a filter plate two is rotatably connected to the inner wall of the cleaning box near the center via a support rod. An outlet is provided on one side of the cleaning box, and a connecting block one is rotatably connected to the opposite side of the filter plate two near the outlet via a support rod.

[0010] Preferably, the movable frame is rotatably connected to a connecting block two via a support rod on the side near the outlet. A telescopic rod is fixedly connected to the opposite side of the connecting block two and the connecting block one. A spring is provided on the outer surface of the telescopic rod, and the spring is fixedly connected to the connecting block one and the connecting block two respectively.

[0011] Preferably, a collection box is fixedly connected to the side of the cleaning box near the bottom, and a filter plate is fixedly connected to the inner wall of the collection box.

[0012] Preferably, a return pipe is fixedly connected to the bottom of the collection box, and the return pipe is fixedly connected to the cleaning box. The collection box, the return pipe, and the cleaning box are interconnected.

[0013] Preferably, the second filter plate is inclined, and the width of the pusher frame is less than the distance between two adjacent conveyor rollers.

[0014] Preferably, a drain pipe is fixedly connected to the other side of the cleaning box near the bottom, the drain pipe is connected to the cleaning box, and a valve is fixedly connected to the outer surface of the drain pipe.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model utilizes the rotation of the conveying rollers to drive the rotation of the disc and the rod. The rod rotates from bottom to top, sliding inside the straight groove and applying an upward force to the movable frame, causing it to move upward. Simultaneously, the sliding strip moves upward along the inside of the groove, and the pushing frame moves upward, allowing it to insert into the gap between two adjacent conveying rollers, applying an upward thrust to the ore. Then, the rod rotates from top to bottom, applying a downward force to the movable frame, causing the movable frame, sliding strip, and pushing frame to move downward. This process is repeated. In this way, when the conveying rollers transport ore, the ore is prevented from getting stuck between the two conveying rollers, avoiding ore accumulation and thus preventing damage to the conveying equipment, thereby extending the service life of the conveying equipment.

[0017] 2. In this utility model, the reciprocating movement of the movable frame causes the connecting block 2 to move upward, applying a pulling force to the telescopic rod, causing it to extend. Simultaneously, the spring is stretched, applying an upward pulling force to the connecting block 1, causing the filter plate 2 to rotate upward. When the connecting block 2 moves upward, the telescopic rod retracts, compressing the spring and applying a downward pushing force to the connecting block 1, causing the filter plate 2 to rotate downward. This process repeats, and under the restoring force of the spring, the filter plate 2 vibrates reciprocally within a certain range. This causes the stones and particulate impurities filtered on the filter plate 2 to roll along the filter plate 2 towards the discharge outlet and fall into the collection box. This not only separates the stones and particulate impurities from the sewage and allows for separate collection and cleaning of the stones and particulate impurities, but also avoids the situation where some small minerals are difficult to collect again due to falling.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Examples, such as Figure 1-4As shown, this utility model provides a mining ore conveying device, including: two conveyor belts 1 and a cleaning box 2, the cleaning box 2 being disposed between the two conveyor belts 1, and further including: multiple conveying rollers 201, equidistantly rotatably connected to opposite sides of the inner wall of the cleaning box 2, multiple sprockets 202 being disposed on one side of the cleaning box 2, wherein two sprockets 202 are respectively fixedly connected to two of the conveying rollers 201, and the other multiple sprockets 202 are respectively fixedly connected to multiple other conveying rollers 201 in pairs, and chains 203 are meshed on the adjacent outer surfaces of the multiple sprockets 202 along different axes, and a motor 212 is fixedly connected to one side of the cleaning box 2. One end of the motor 212 is fixedly connected to one end of a conveying roller 201. Both ends of the other two conveying rollers 201 are fixedly connected to a disc 204. A round rod 205 is fixedly connected to the eccentric part of the disc 204. Multiple sliding grooves 208 are equally spaced on opposite sides of the cleaning box 2. Sliding strips 209 are slidably connected inside the two sliding grooves 208. A push frame 211 is fixedly connected to the top of the sliding strips 209. A movable frame 206 is fixedly connected to the opposite sides of the multiple sliding strips 209. A straight groove 207 is opened on the side of the movable frame 206 near the top. The outer surfaces of the two round rods 205 are slidably connected inside the straight groove 207.

[0027] Furthermore, such as Figure 1-4 As shown, two conveying pipes 3 are symmetrically fixedly connected to the top of the cleaning box 2. One end of the conveying pipe 3 is fixedly connected to a guide pipe 301. Multiple nozzles 302 are fixedly connected at equal intervals on the outer surface of the guide pipe 301. The conveying pipe 3, the guide pipe 301 and the multiple nozzles 302 are connected. Water is delivered into the conveying pipe 3 by an external water pump. The water passes through the conveying pipe 3, the guide pipe 301 and the nozzles 302 in sequence and is sprayed onto the surface of the mine to wash the soil on the surface of the ore. The stones, particulate impurities and sewage fall down from the gap between the two conveying rollers 201.

[0028] Furthermore, such as Figure 1-4 As shown, a filter plate 402 is rotatably connected to the inner wall of the cleaning box 2 near the center via a support rod. A discharge port 210 is provided on one side of the cleaning box 2. A connecting block 403 is rotatably connected to the filter plate 402 near the discharge port 210 via a support rod. With the above arrangement, the filter plate 402 can be rotated.

[0029] Furthermore, such as Figure 1-4As shown, a connecting block 406 is rotatably connected to the side of the movable frame 206 near the outlet 210 via a support rod. A telescopic rod 404 is fixedly connected to the opposite side of connecting block 406 and connecting block 403. A spring 405 is provided on the outer surface of the telescopic rod 404, and the spring 405 is fixedly connected to both connecting block 403 and connecting block 406. Through this arrangement, when connecting block 406 is moved upwards, it can apply a pulling force to the telescopic rod 404, causing the telescopic rod 404 to... 04 extends, simultaneously stretching the spring 405 and applying an upward pulling force to the connecting block 403, causing the filter plate 402 to rotate upward. When the connecting block 406 moves upward, the telescopic rod 404 retracts, compressing the spring 405 and applying a downward pushing force to the connecting block 403, causing the filter plate 402 to rotate downward. This process is repeated, and under the restoring force of the spring 405, the filter plate 402 can reciprocate within a certain range.

[0030] Furthermore, such as Figure 1-4 As shown, a collection box 4 is fixedly connected to the bottom side of the cleaning box 2. A filter plate 401 is fixedly connected to the inner wall of the collection box 4. The collection box 4 facilitates the collection of stones and particulate impurities, and the filter plate 401 facilitates the filtration of stones and particulate impurities.

[0031] Furthermore, such as Figure 1-4 As shown, a return pipe 407 is fixedly connected to the bottom of the collection box 4. The return pipe 407 is fixedly connected to the cleaning box 2. The collection box 4, the return pipe 407 and the cleaning box 2 are connected. The return pipe 407 facilitates the return of sewage entering the collection box 4 to the cleaning box 2.

[0032] Furthermore, such as Figure 1-4 As shown, the filter plate 402 is set in an inclined shape, and the width of the pusher 211 is less than the distance between two adjacent conveying rollers 201. By setting the filter plate 402 in an inclined shape, it is convenient for stones and particulate impurities to roll to one side, and the pusher 211 can be inserted between two adjacent conveying rollers 201.

[0033] Furthermore, such as Figure 1-4 As shown, a drain pipe is fixedly connected to the other side of the cleaning tank 2 near the bottom. The drain pipe is connected to the cleaning tank 2, and a valve is fixedly connected to the outer surface of the drain pipe. By opening the valve, the sewage inside the cleaning tank 2 can be discharged through the drain pipe.

[0034] Working Principle: In operation, the ore is conveyed via conveyor belt 1. The controller starts motor 212, causing its output shaft to drive the connected conveyor rollers 201 to rotate. This synchronously drives the connected sprocket 202 to rotate. Then, under the meshing action of the sprocket 202 and chain 203, the remaining conveyor rollers 201 rotate in the same direction, conveying the ore. Simultaneously, the disc 204 and the rod 205 rotate, causing the rod 205 to rotate from bottom to top. This allows the rod 205 to slide inside the straight groove 207, applying an upward force to the movable frame 206, causing it to move upwards. Simultaneously, the slide bar 209 moves upwards along the inside of the chute 208, and the pusher frame 211 moves upwards. The pusher frame 211 is inserted into the gap between two adjacent conveyor rollers 201, applying an upward thrust to the ore. Then, the round rod 205 rotates from top to bottom, applying a downward force to the movable frame 206, causing the movable frame 206, slide bar 209, and pusher frame 211 to move downwards. This process is repeated to prevent the ore from getting stuck between the two conveyor rollers 201 when the conveyor rollers 201 are conveying the ore, thus preventing ore accumulation and damage to the conveying equipment, and extending the service life of the conveying equipment. Simultaneously, water is pumped into the conveying pipe 3 by an external water pump, and the water passes through the conveying pipe 3, guide pipe 301, and nozzle 302 in sequence, spraying onto the mine surface to wash away the mud on the ore surface and allow the stones to pass through. Particulate impurities and wastewater flow downwards through the gap between the two conveying rollers 201, and are filtered by the filter plate 402. Wastewater flows into the bottom of the cleaning box 2. Simultaneously, the movable frame 206 moves up and down. When the connecting block 406 moves upwards, it applies a pulling force to the telescopic rod 404, causing it to extend. Simultaneously, the spring 405 is stretched, applying an upward pulling force to the connecting block 403, causing the filter plate 402 to rotate upwards. When the connecting block 406 moves upwards, it retracts the telescopic rod 404, compressing the spring 405 and applying a downward pushing force to the connecting block 403, causing the filter plate 402 to rotate upwards. The filter plate 402 rotates downwards repeatedly, and under the restoring force of the spring 405, the filter plate 402 can reciprocate within a certain range. This causes the stones and particulate impurities filtered on the filter plate 402 to roll along the filter plate 402 towards the discharge outlet 210 and fall into the collection box 4. This not only separates the stones and particulate impurities from the sewage and allows for separate collection and cleaning of the stones and particulate impurities, but also avoids the situation where some small minerals are difficult to collect again after falling. Some sewage will enter the collection box 4 along with the stones and particulate impurities. The stones and particulate impurities can be filtered by the filter plate 401, allowing the sewage to flow into the bottom of the collection box 4 and return to the interior of the cleaning box 2 through the return pipe 407.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
