Description

Technical Field

[0001] This application relates to the technical field of ore mining equipment, and in particular to an automatic conveying device for underground ore crushing. Background Technology

[0002] In today's mineral resource mining field, the efficient processing and transportation of underground ore is a key link in ensuring mine production efficiency and economic benefits. In order to facilitate the transportation of mined ore, it is necessary to crush and centrally transport and collect the mined ore underground. This requires underground ore crushing and conveying equipment to crush the mined ore and put it onto the conveying mechanism for centralized collection.

[0003] Currently, after the ore is crushed by the crushing mechanism, it falls directly onto the conveyor belt for transportation. When special circumstances occur during transportation that cause the conveyor belt to stop working, or when a large amount of ore is fed onto the conveyor belt in a short period of time, a large amount of ore will accumulate on the conveyor belt due to the crushing mechanism, resulting in the ore scattering off the conveyor belt and affecting the efficiency of ore transportation. Utility Model Content

[0004] The purpose of this application is to provide an automatic underground ore crushing and conveying device, which has the advantages of being able to control the amount of crushed ore fed onto the conveyor belt, so that the crushed ore can be evenly fed onto the conveyor belt, and automatically stopping the conveying of ore onto the conveyor belt when the conveyor belt stops working, thus avoiding the situation where a large amount of ore accumulates on the conveyor belt and scatters from the conveyor belt. This solves the problem that currently, after the ore is crushed by the crushing mechanism, it falls directly onto the conveyor belt for conveying. When special circumstances cause the conveyor belt to stop working or when a large amount of ore is fed onto the conveyor belt in a short period of time, a large amount of crushed ore will accumulate on the conveyor belt, resulting in the ore scattering from the conveyor belt and affecting the working efficiency of ore conveying.

[0005] The automatic conveying equipment for underground ore crushing provided in this application adopts the following technical solution: An automatic conveying equipment for underground ore crushing includes a base, and a crushing assembly is provided above the base. The crushing assembly includes a crushing box, and two crushing rollers are provided inside the crushing box. A rotating shaft is provided on the inner wall of the middle portion of each of the two crushing rollers. The outer surfaces of both ends of the rotating shaft are rotatably disposed within the inner walls of both sides of the crushing box. Gears are provided on the outer surfaces of one end of each of the two rotating shafts, and the two gears mesh with each other. One end of one of the rotating shafts is disposed on the first… At one end of the motor output shaft, the first motor is mounted on one side of the crushing box via a fixing bracket. A storage box is provided at the bottom outlet of the crushing box, and a discharge pipe is provided at the bottom outlet of the storage box. A chain conveyor mechanism is provided below the discharge pipe. The chain conveyor mechanism includes a conveyor chain belt. The inner walls of both ends of the conveyor chain belt are sleeved on the middle outer surface of two first drive rollers. The conveyor chain belt is connected to the first drive rollers. Multiple pusher plates are arranged at equal intervals on the outer surface of the conveyor chain belt. The pusher plates are located inside the discharge pipe. The discharge pipe has openings on both sides. A first support shaft is provided within the inner wall of the middle portion of each of the two first transmission rollers. The outer surfaces of both ends of the first support shaft are rotatably mounted within the inner wall of one end of a support rod. The other end of the support rod is located on the top of a support plate. A material conveying mechanism is provided below the discharge end of the conveyor chain belt. The material conveying mechanism includes a conveyor belt. The inner walls of both ends of the conveyor belt are sleeved on the outer surface of the middle portion of the two second transmission rollers. A second support shaft is provided within the inner wall of the middle portion of each of the two second transmission rollers. The outer surfaces of both ends of the second support shaft are rotatably mounted within the inner walls of both sides of the bracket. A first synchronous pulley is provided at one end of a first support shaft near the material conveying mechanism. A second synchronous pulley is provided on the outer surface of one end of a second support shaft near the chain conveying mechanism. The first and second synchronous pulleys are connected by a synchronous belt drive. One end of a second support shaft near the chain conveying mechanism is located at one end of the output shaft of a second motor. The bottom of the second motor is mounted on one side of the bracket via a fixing frame. The bottom of the storage box is mounted on the top of the base via support legs.

[0006] By adopting the above technical solution, when the material conveying mechanism is working, the rotation of the second transmission roller will cause the corresponding second support shaft to drive the second synchronous wheel to rotate, so that the second synchronous wheel drives the first synchronous wheel to rotate synchronously through the synchronous belt, and then drives the first transmission roller to rotate through the first support shaft, so that the conveyor chain belt drives the pusher plate to move, and then the pusher plate pushes the ore in the discharge pipe to be put onto the conveyor belt. When the material conveying mechanism is working, it drives the chain conveyor mechanism to work to put the ore onto it, so that the amount of crushed ore put onto the conveyor belt can be controlled, so that the crushed ore can be evenly put onto the conveyor belt. When the conveyor belt stops working, it can automatically stop conveying ore onto the conveyor belt, avoiding the situation where a large amount of ore will accumulate on the conveyor belt and scatter.

[0007] Preferably, the bottom of the support plate is provided with four support wheels that are rotatably connected by a connecting frame, and the four support wheels are arranged in two rows.

[0008] By adopting the above technical solution, the support wheel can support the chain conveyor mechanism through the support plate. When the parts of the chain conveyor mechanism are severely worn and need to be repaired or replaced, the chain conveyor mechanism can be easily pulled out from under the storage box, thus facilitating the repair and replacement of the chain conveyor mechanism.

[0009] Preferably, the two rows of support wheels are slidably disposed in the middle inner wall of the two positioning grooves, both positioning grooves are disposed on the top of the base, one end of the positioning groove is provided with an opening, and the other end of the positioning groove is provided with a positioning plate.

[0010] By adopting the above technical solution, the travel trajectory of the support wheel can be fixed by setting the positioning groove, thereby fixing the travel trajectory of the chain conveyor mechanism under the storage box. Furthermore, by sealing the end of the positioning groove with the positioning plate, the travel position of the support wheel in the positioning groove can be restricted. This allows the support wheel to drive the chain conveyor mechanism to move and stop at the designated position under the storage box, avoiding trajectory deviation when moving the chain conveyor mechanism under the storage box, and enabling the chain conveyor mechanism to move accurately under the storage box.

[0011] Preferably, the top of the base is provided with two limiting plates, which are located on both sides of the support plate. A limiting rod is inserted into the inner wall of the middle part of the support plate, and the outer surfaces of both ends of the limiting rod are inserted into the inner wall of one end of the two limiting plates.

[0012] By adopting the above technical solution, the two ends of the limiting rod are inserted into the inner wall of one end of the two limiting plates, and the middle part of the limiting rod is inserted into the inner wall of the middle part of the support plate. The position of the support plate can be fixed, and the chain conveyor mechanism can be stably fixed below the storage box to prevent the chain conveyor mechanism from shifting during operation.

[0013] Preferably, the support rod near the material conveying mechanism is inclined.

[0014] By adopting the above technical solution, the inclined support rod close to the material conveying mechanism can leave a certain space for the installation of the material conveying mechanism, and avoid the setting of the support rod from interfering with the installation of the material conveying mechanism, which would prevent one end of the material conveying mechanism from being installed below the discharge end of the chain conveyor mechanism.

[0015] Preferably, the width of the pusher plate is adapted to the distance between the two sides of the inner wall of the discharge pipe, the two outer surfaces of the pusher plate are slidably connected to the two outer surfaces of the inner wall of the discharge pipe, and there is a gap between the end of the pusher plate away from the conveyor chain and the top of the openings on both sides of the discharge pipe.

[0016] By adopting the above technical solution, the pusher plate can stably push the material falling from the discharge pipe onto the conveyor belt, preventing the material from accumulating below the discharge pipe and preventing the ore from leaking out from the gap between the pusher plate and the inner wall of the discharge pipe. The gap between the pusher plate and the top of the discharge pipe opening will not affect the normal movement of the pusher plate, and will also prevent the ore from blocking the opening, ensuring that the pusher plate can smoothly push the ore in the discharge pipe out of the discharge pipe from the opening on the side of the discharge pipe.

[0017] Preferably, a first baffle is provided at the edge of the opening on both sides of the discharge pipe. The first baffle is located on the outside of the conveyor chain belt, and one outer surface of the first baffle is slidably connected to one outer surface of the pusher plate.

[0018] By adopting the above technical solution, the first baffle can block the opening of the discharge pipe to prevent the ore from sliding off the side of the pusher plate. At the same time, the first baffle is slidably connected to the pusher plate, so that the pusher plate can move smoothly between the two corresponding first baffles, ensuring the safety and reliability of the ore conveying process.

[0019] Preferably, a second baffle is provided on both sides of the top of the bracket, and the two second baffles are located on both sides of the conveyor belt.

[0020] By adopting the above technical solution, the second baffle can block the ore on the conveyor belt, prevent the ore from falling from both sides of the conveyor belt during the conveying process, avoid ore waste and impact on the working environment, and improve the efficiency of ore conveying.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This underground ore crushing and automatic conveying equipment, when the material conveying mechanism is working, the rotation of the second transmission roller will cause the corresponding second support shaft to drive the second synchronous wheel to rotate, so that the second synchronous wheel drives the first synchronous wheel to rotate synchronously through the synchronous belt, and then drives the first transmission roller to rotate through the first support shaft. This causes the conveyor chain plate to drive the pusher plate to move, and then the pusher plate pushes the ore in the discharge pipe to be put onto the conveyor belt. The material conveying mechanism works while driving the chain plate conveying mechanism to put ore onto it, so that the amount of crushed ore put onto the conveyor belt can be controlled, and the crushed ore can be evenly put onto the conveyor belt. When the conveyor belt stops working, the equipment can automatically stop conveying ore onto the conveyor belt, so as to avoid the ore accumulating on the conveyor belt and scattering.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0025] Example 1: An automatic conveying device for underground ore crushing, please refer to... Figure 1 , Figure 5 and Figure 6The system includes a base 1, with a crushing assembly 2 positioned above the base 1. The crushing assembly 2 includes a crushing box 201, inside which are two crushing rollers 202. A rotating shaft 205 is mounted on the inner wall of the middle section of each of the two crushing rollers 202. The outer surfaces of both ends of the rotating shafts 205 are rotatably mounted within the inner walls of both sides of the crushing box 201. A gear 203 is mounted on the outer surface of one end of each rotating shaft 205, and the two gears 203 mesh with each other. One end of one rotating shaft 205 is connected to one end of the output shaft of a first motor 204, which is mounted on the crushing box 201 via a mounting bracket. On one side, a storage box 3 is provided at the bottom discharge port of the crushing box 201. A discharge pipe 4 is provided at the bottom discharge port of the storage box 3. A chain conveyor mechanism 5 is provided below the discharge pipe 4. The chain conveyor mechanism 5 includes a conveyor chain belt 501. The inner walls of both ends of the conveyor chain belt 501 are sleeved on the middle outer surface of two first drive rollers 502. The conveyor chain belt 501 is connected to the first drive rollers 502. Multiple pusher plates 506 are arranged at equal intervals on the outer surface of the conveyor chain belt 501. The pusher plates 506 are located inside the discharge pipe 4. Openings are opened on both sides of the discharge pipe 4. Each roller 502 has a first support shaft 503 installed inside its middle inner wall. The outer surfaces of both ends of the first support shaft 503 are rotatably mounted inside the inner wall of one end of a support rod 504. The other end of the support rod 504 is located on the top of a support plate 505. A material conveying mechanism 6 is located below the discharge end of the conveyor chain belt 501. The material conveying mechanism 6 includes a conveyor belt 601. The inner walls of both ends of the conveyor belt 601 are sleeved on the middle outer surfaces of two second drive rollers 602. Each of the two second drive rollers 602 has a second support shaft 603 installed inside its middle inner wall. The outer surfaces of both ends of the second support shaft 603 are rotatably mounted inside its middle inner wall. The first synchronous wheel 7 is provided at one end of a first support shaft 503 near the material conveying mechanism 6, and a second synchronous wheel 8 is provided on the outer surface of one end of a second support shaft 603 near the chain conveying mechanism 5. The first synchronous wheel 7 and the second synchronous wheel 8 are connected by a synchronous belt 9. One end of the second support shaft 603 near the chain conveying mechanism 5 is located at one end of the output shaft of the second motor 605. The bottom of the second motor 605 is fixed to one side of the support 604 by a fixing bracket. The bottom of the storage box 3 is fixed to the top of the base 1 by a support leg.

[0026] Please see Figure 2 , Figure 5 and Figure 6 The support rod 504 near the material conveying mechanism 6 is inclined. The inclined support rod 504 near the material conveying mechanism 6 can leave a certain space for the installation of the material conveying mechanism 6, so as to avoid the setting of the support rod 504 interfering with the installation of the material conveying mechanism 6 and causing one end of the material conveying mechanism 6 to be unable to be installed below the discharge end of the chain conveyor mechanism 5.

[0027] Please see Figure 1 , Figure 3 and Figure 4 The width of the pusher plate 506 is adapted to the distance between the two sides of the inner wall of the discharge pipe 4. The outer surfaces of the two sides of the pusher plate 506 are slidably connected to the outer surfaces of the two sides of the inner wall of the discharge pipe 4. There is a gap between the end of the pusher plate 506 away from the conveyor chain belt 501 and the top of the openings on both sides of the discharge pipe 4. The pusher plate 506 can stably push the material falling from the discharge pipe 4 onto the conveyor chain belt 501 to move, avoiding the accumulation of material under the discharge pipe 4 and preventing the ore from leaking out from the gap between the pusher plate 506 and the inner wall of the discharge pipe 4. The gap between the pusher plate 506 and the top of the opening of the discharge pipe 4 will not affect the normal movement of the pusher plate 506, and will also prevent the ore from blocking the opening, ensuring that the pusher plate 506 can smoothly push the ore in the discharge pipe 4 out of the opening on the side of the discharge pipe 4.

[0028] Please see Figure 1 , Figure 3 and Figure 4 First baffles 14 are provided at the edges of the openings on both sides of the discharge pipe 4. The first baffles 14 are located on the outside of the conveyor chain belt 501. One outer surface of the first baffle 14 is slidably connected to one outer surface of the pusher plate 506. The first baffles 14 can block the openings of the discharge pipe 4 to prevent the ore from sliding off the side of the pusher plate 506. At the same time, the first baffles 14 and the pusher plate 506 are slidably connected, so that the pusher plate 506 can move smoothly between the two corresponding first baffles 14, ensuring the safety and reliability of the ore conveying process.

[0029] Please see Figure 1 , Figure 2 and Figure 4 The support 604 has two second baffles 15 on its top sides. The two second baffles 15 are located on both sides of the conveyor belt 601. The second baffles 15 can block the ore on the conveyor belt 601, prevent the ore from falling from both sides of the conveyor belt 601 during the conveying process, avoid ore waste and impact on the working environment, and improve the efficiency of ore conveying.

[0030] Example 2: An automatic conveying device for underground ore crushing, please refer to... Figure 2 and Figure 3 The bottom of the support plate 505 is rotatably equipped with four support wheels 10 through the connecting frame. The four support wheels 10 are arranged in two rows. The support wheels 10 can support the chain conveyor mechanism 5 through the support plate 505. When the parts of the chain conveyor mechanism 5 are severely worn and need to be repaired or replaced, the chain conveyor mechanism 5 can be easily pulled out from under the storage box 3, so that the chain conveyor mechanism 5 can be easily repaired or replaced.

[0031] Please see Figure 2 , Figure 3 and Figure 5 Two rows of support wheels 10 are slidably disposed within the inner wall of the middle portion of two positioning grooves 11. Both positioning grooves 11 are disposed on the top of the base 1. One end of the positioning groove 11 is open, and the other end of the positioning groove 11 is provided with a positioning plate 16. The positioning groove 11 can fix the travel trajectory of the support wheels 10, thereby fixing the travel trajectory of the chain conveyor mechanism 5 below the storage box 3. Furthermore, the positioning plate 16 can block the end of the positioning groove 11, thus restricting the travel position of the support wheels 10 within the positioning groove 11. This allows the support wheels 10 to drive the chain conveyor mechanism 5 to move and stop at a designated position below the storage box 3, preventing trajectory deviation when the chain conveyor mechanism 5 is moved below the storage box 3. This ensures that the chain conveyor mechanism 5 can move precisely below the storage box 3.

[0032] Please see Figure 1 , Figure 2 and Figure 3 The base 1 has two limiting plates 12 on its top, which are located on both sides of the support plate 505. A limiting rod 13 is inserted into the inner wall of the middle part of the support plate 505. The outer surfaces of both ends of the limiting rod 13 are inserted into the inner wall of one end of the two limiting plates 12. The two ends of the limiting rod 13 are inserted into the inner wall of one end of the two limiting plates 12, and the middle part of the limiting rod 13 is inserted into the inner wall of the middle part of the support plate 505. This can fix the position of the support plate 505, thereby stably fixing the chain conveyor mechanism 5 below the storage box 3 and preventing the chain conveyor mechanism 5 from shifting during operation.

[0033] The implementation principle of this application embodiment is as follows: First, the ore to be crushed is put into the crushing box 201, and the first motor 204 is started. The first motor 204 drives one of the rotating shafts 205 to rotate, which in turn drives the other rotating shaft 205 to rotate through two meshing gears 203. This causes the two crushing rollers 202 to rotate relative to each other to crush the ore. The crushed ore falls into the storage box 3, and the ore in the storage box 3 will fall onto the conveyor chain 501 through the discharge pipe 4. Then, the second motor 605 is started, and the second motor 605 will pass through the corresponding second support... The support shaft 603 drives the corresponding second drive roller 602 to rotate, causing the two second drive rollers 602 to cooperate in driving the conveyor belt 601 to rotate. When the corresponding second support shaft 603 rotates, it drives the second synchronous pulley 8 to rotate, causing the second synchronous pulley 8 to drive the first synchronous pulley 7 to rotate via the synchronous belt 9. The first synchronous pulley 7 drives the corresponding first drive roller 502 to rotate via the corresponding first support shaft 503, causing the two first drive rollers 502 to cooperate in driving the conveyor chain belt 501 to rotate. When the conveyor chain belt 501 rotates, it drives the pusher plate 506 to move. The pusher plate 506 pushes the material falling onto the conveyor belt 501 from inside the discharge pipe 4 to the outside of the discharge pipe 4. When the conveyor belt 501 is running, it works with the pusher plate 506 to continuously feed the ore from the storage bin 3 onto the conveyor belt 501 through the discharge pipe 4. The continuous operation of the conveyor belt 501 pushes the ore onto the running conveyor belt 601, thus ensuring that the ore is evenly fed onto the conveyor belt 601 for transport. When the conveyor belt 601 stops working, the first synchronous pulley 7, the second synchronous pulley 8, and the synchronous belt 9 work together to keep the chain moving. The conveyor plate mechanism 5 then stops working, allowing the ore crushed by the crushing component 2 to be temporarily stored in the storage box 3. The ore in the storage box 3 is temporarily stopped by the conveyor chain 501 and the pusher plate 506. When it is necessary to repair or replace the parts of the conveyor chain mechanism 5, the synchronous belt 9 is removed from the first synchronous pulley 7 and the second synchronous pulley 8, the limit rod 13 is pulled out from the inside of the limit plate 12 and the support plate 505, the fixation of the conveyor chain mechanism 5 is released, and the conveyor chain mechanism 5 is moved away from the bottom of the storage box 3 by the support wheel 10 for repair.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
