[0016] The beneficial effects of the present invention are as follows: 1. For the mining conveying device with a screening function described in the present invention, by using the discharge orientation control component, during the material conveying process, the baffle and the baffle cloth can be used to block the material to prevent the material from falling off the conveyor belt in advance. At the same time, by adjusting the position of the discharge port, the discharge orientation of the material is controlled, so as to meet different discharge requirements. And when the material is discharged through the discharge port, the discharge range of the material can be controlled to avoid the situation that the material falls outside the receiving port of the receiving device because the area of the receiving port of the receiving device is smaller than the discharge port, which affects the normal material receiving. In addition, the discharge range is reasonably set according to the area of the receiving port of the receiving device, which can maximize the discharge speed on the premise of ensuring that the material can accurately fall into the receiving device. Since the length of the unreeled part of the pushing cloth is the same as the preset length, when the pushing cloth moves horizontally, the situation that the material is squeezed between the pushing cloth and the baffle cloth, resulting in damage to the pushing cloth and the baffle cloth, will not occur, which is beneficial to extending the service life of the pushing cloth and the baffle cloth.

[0017] 2. A mining conveying device with a screening function according to the present invention utilizes a multi-channel discharging assembly. With the cooperation of multiple partition plates and opening plates, multiple discharging channels are formed. Moreover, when the materials are picked up by multiple receiving ports with the same specifications and evenly distributed, the spacing and specifications of the multiple discharging channels can be adjusted according to the number, width of the receiving ports, and the spacing between two adjacent receiving ports, so that the multiple discharging channels correspond to the multiple receiving ports. When the materials are pushed out by the pushing cloth, the materials will evenly fall into the multiple receiving ports through the discharging channels, thereby improving the evenness of material receiving. At the same time, it also avoids the situation where the materials fall into the gap between two adjacent receiving ports when the materials are discharged through the discharging ports, which is beneficial to the subsequent distribution and transfer of the materials.

[0018] 3. A mining conveying device with a screening function according to the present invention utilizes an anti-jamming assembly. According to the angle of the opening plate, the trough plate is parallel to the opening plate, and at the same time, the anti-jamming rod is attached to one side surface of the opening plate. When the materials are discharged through the discharging channel, the anti-jamming rod will move along one side surface of the opening plate, pushing the materials in contact with the opening plate, and then promoting the movement of the attached materials, avoiding the situation where the materials are jammed at the opening plate when discharged due to the non-parallel movement trajectory between the opening plate and the materials, which affects the normal material receiving. In addition, the cylinder two drives the moving block to move, which can adjust the distance between the anti-jamming rod and the opening plate, expand the moving range of the anti-jamming rod, and improve the anti-jamming effect.

[0019] 4. A mining conveying device with a screening function according to the present invention, before the materials are placed on the conveyor belt, the materials are first placed on the screen of the vibrating screen. During the process of the materials sliding down along the screen, the vibrating screen generates vibration to screen out the impurities in the materials and fall into the collection box. Then, after the materials fall on the conveyor belt, the impurities in them have been removed, thereby improving the purity and quality of the materials, which is beneficial to the subsequent processing work.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-11 , the present invention provides a technical solution: a mining conveying device with a screening function, including a frame 1, a conveyor belt 2 is arranged on the frame 1, and a discharge orientation control component is also arranged on the frame 1; The discharge orientation control component includes a baffle 3 fixedly connected to one side of the upper end of the frame 1. First winding and unwinding rollers 9 are rotatably arranged on both sides of the upper end of the frame 1. The same cloth baffle 4 is wound around the two first winding and unwinding rollers 9. A discharge port 28 is arranged on one side of the cloth baffle 4. A cutting plate 7 is slidably connected to the chute on one side of the baffle 3. A threaded block 19 is slidably connected to one side of the cutting plate 7. One side of the upper end surface of the threaded block 19 is fixedly connected to a first cylinder 20. The piston end of the first cylinder 20 is fixedly connected to a lifting plate 21. A second winding and unwinding roller 26 is rotatably arranged on one side of the lifting plate 21. A pushing cloth 27 is wound around the second winding and unwinding roller 26. One end of the pushing cloth 27 is fixedly connected to a rack bar 22, and the rack bar 22 is slidably connected to the lifting plate 21.

[0025] In this embodiment, asFigures 1-8 As shown, on both sides of the upper end of the frame 1, a first motor 8 is fixedly connected. The output end of the first motor 8 is fixedly connected to one end of the winding and unwinding roller 9.

[0026] On one side of the cutting plate 7, a third threaded rod 29 is threadedly connected. Both ends of the third threaded rod 29 are rotatably arranged on the baffle 3. One end of the baffle 3 is fixedly connected to a ninth motor 39. The output end of the ninth motor 39 is fixedly connected to one end of the third threaded rod 29.

[0027] One end of the threaded block 19 is threadedly connected to a second threaded rod 18. Both ends of the second threaded rod 18 are rotatably arranged on the cutting plate 7. On one side of the cutting plate 7, a fifth motor 30 is fixedly connected. The output end of the fifth motor 30 is fixedly connected to one end of the second threaded rod 18. On one side of the lifting plate 21, a fourth motor 25 is fixedly connected. The output end of the fourth motor 25 is fixedly connected to one end of the winding and unwinding roller 26. On one side of the upper end of the lifting plate 21, a gear 23 is rotatably arranged. The gear 23 meshes with the tooth blocks on the rack bar 22. On one side of the upper end of the lifting plate 21, a third motor 24 is fixedly connected. The output end of the third motor 24 is fixedly connected to the gear 23.

[0028] Specifically, when the existing mine belt conveyor is in use, the material to be conveyed is placed at one end of the conveyor belt 2. After the material moves to the other end of the conveyor belt 2, it drops, thereby realizing the conveyance of the material. At the same time, during the conveyance process, the two sides of the material on the conveyor belt 2 can be blocked to prevent the material from dropping. However, in some cases, the receiving device may not be set at the end of the conveyor belt 2, but at any position on the side of the conveyor belt 2. Therefore, it is necessary to unload the material from a non-end position of the conveyor belt 2. In the prior art, the material can only be unloaded from the end of the conveyor belt 2. Therefore, it is difficult to meet different unloading requirements.

[0029] Therefore, to solve the above problems, when this embodiment is in use, the bulk materials such as coal or ore to be conveyed are placed at one end of the conveyor belt 2. According to the position of the receiving equipment, the motors 8 on both sides are started simultaneously. The winding rollers 9 are driven to rotate by the motors 8 on both sides. Since the same baffle cloth 4 is wound around the two winding rollers 9, the two winding rollers 9 cooperate with each other to adjust the position of the discharge port 28 on the baffle cloth 4. Then, by driving the rotation of the threaded rod 29 by the motor 39, the cutting plate 7 slides on the baffle 3 to adjust the position of the cutting plate 7 so that one side edge of the cutting plate 7 coincides with one side edge of the discharge port 28. Then, the conveyor belt 2 is driven to operate, and the conveyor belt 2 drives the materials to move towards the discharge port 28. When the materials are blocked by the cutting plate 7, the motor 30 drives the rotation of the threaded rod 18, so that the threaded block 19 moves horizontally on the cutting plate 7, and the pushing cloth 27 approaches the discharge port 28. Since the initial position of the pushing cloth 27 is at the edge of the baffle 3, the pushing cloth 27 can push the materials within the range of its unreeled part towards the discharge port 28, and the materials can be unloaded through the discharge port 28. Therefore, during the material conveying process, the baffle 3 and the baffle cloth 4 can be used to block the materials to prevent the materials from falling off the conveyor belt 2 in advance, and the unloading orientation of the materials can be controlled by adjusting the position of the discharge port 28, so as to meet different unloading requirements. When the pushing cloth 27 completes a pushing action, the air cylinder 20 drives the lifting plate 21 to rise, so that the bottom of the pushing cloth 27 is far away from the conveyor belt 2, and then the pushing cloth 27 is reset horizontally. When the pushing cloth 27 is at the edge of the baffle 3, the pushing cloth 27 descends again to fit with the conveyor belt 2, which can avoid the situation that when the pushing cloth 27 is reset, the subsequent materials reaching the cutting plate 7 are pushed towards the baffle 3, resulting in the subsequent abnormal operation of the pushing cloth 27. Then, by repeating the above operations, the continuous unloading of the materials can be realized. Although the discharging orientation of the material can be controlled in the above manner, the discharging range of the material is the same as the size of the discharge port 28. In some cases, the receiving port area of the receiving device is smaller than the discharge port 28, which will cause the material to fall outside the receiving port when the receiving device receives the material, thus affecting the normal material receiving. When the discharge port 28 is set too small to avoid the above problems, the discharging speed will be affected. Therefore, to solve this problem, first adjust the position of the material intercepting plate 7 within the discharge port 28, and then according to the length between the material intercepting plate 7 and one side edge of the discharge port 28, and record this length as the preset length. At the same time, start the fourth motor 25 and the third motor 24. The fourth motor 25 drives the second winding and unwinding roller 26 to rotate, and the third motor 24 drives the gear 23 to rotate, so that the rack bar 22 moves horizontally. The rack bar 22 drives the end of the pushing cloth 27 to move. At the same time, in cooperation with the winding and unwinding of the pushing cloth 27, the length of the unreeled part of the pushing cloth 27 is the same as the above preset length. Then when the pushing cloth 27 pushes the material, only the material within the preset length range will be pushed, thus realizing the control of the material discharging range, avoiding the situation that when the receiving port area of the receiving device is smaller than the discharge port 28 and the receiving device receives the material, the material falls outside the receiving port and affects the normal material receiving. In addition, the discharging range depends on the receiving port area of the receiving device, which maximally ensures the discharging speed. And because the length of the unreeled part of the pushing cloth 27 is equal to the preset length, when the pushing cloth 27 moves horizontally, the situation that the pushing cloth 27 and the baffle cloth 4 are damaged due to the material being squeezed between the pushing cloth 27 and the baffle cloth 4 will not occur, which is beneficial to extending the service life of the pushing cloth 27 and the baffle cloth 4.

[0030] In this embodiment, as Figure 4 , Figures 8-11 shown, a multi-channel discharging component is further arranged on the frame 1; The multi-channel discharging component includes a mounting rod 12 slidably connected to one side of the frame 1. A plurality of partition plates 13 are horizontally arranged at equal intervals on the upper side of the mounting rod 12. The leftmost partition plate 13 is fixedly connected to the mounting rod 12, and the rest of the partition plates 13 are slidably connected to the mounting rod 12. An opening plate 14 is rotatably arranged on one side of the partition plate 13, and one side of the partition plate 13 is flush with one side surface of the baffle cloth 4.

[0031] One side of the lower end of the mounting rod 12 is threadedly connected with a first threaded rod 11. Both ends of the first threaded rod 11 are rotatably arranged on the frame 1. A second motor 10 is fixedly connected to one side of the frame 1, and the output end of the second motor 10 is fixedly connected to one end of the first threaded rod 11.

[0032] Two connecting rods one 16 are rotatably arranged at the upper ends of the leftmost and rightmost partitions 13, and two connecting rods two 17 are rotatably arranged at the upper ends of the remaining partitions 13. One end of the connecting rod one 16 is rotatably connected to one end of the connecting rod two 17, and the ends of adjacent two connecting rods two 17 are rotatably connected. One side of the upper end of the mounting rod 12 is fixedly connected with an electric push rod 15, and the piston end of the electric push rod 15 is fixedly connected with one end of the rightmost partition 13. One side of the partition 13 is fixedly connected with a motor eight 38, and the output end of the motor eight 38 is fixedly connected with one end of the opening plate 14.

[0033] Specifically, in the above embodiment, although the control of the discharging position and the discharging range can be realized, in some cases, multiple receiving ports are used simultaneously to receive materials to achieve the distribution of materials. And, in order to improve the uniformity of material receiving and make it more convenient to transfer materials to other processes, multiple receiving ports with the same specifications are used, and these receiving ports are equally spaced. This setting method is relatively common in mining production. If the materials are directly discharged from the discharge port 28, it will cause the materials to fall unevenly into different receiving ports, and the materials are likely to fall into the gap between adjacent two receiving ports, thus affecting the distribution of materials and the subsequent transfer work. Therefore, to solve the above problems, when this embodiment is in use, after the positions of the discharge port 28 and the intercepting plate 7 are determined, the motor two 10 is used to drive the threaded rod one 11 to rotate, so that the mounting rod 12 slides on one side of the frame 1, and the position of the leftmost partition 13 is adjusted to make the edge of this partition 13 align with the left edge of the discharge port 28, and the space between adjacent two partitions 13 serves as a discharge channel. By driving the opening plate 14 to rotate with the motor eight 38, the distance between the end of the opening plate 14 and the partition 13 is adjusted, and then the width of the discharge channel can be adjusted to be equal to the width of the receiving port. Then, according to the spacing of multiple equally spaced receiving ports, the electric push rod 15 is used to drive the rightmost partition 13 to slide on the mounting rod 12. Then, with the cooperation of the connecting rod one 16 and the connecting rod two 17, the distance between adjacent two partitions 13 can be adjusted, and at the same time, the opening plate 14 continuously rotates to adapt to the change of the distance between adjacent partitions 13, so that the width of the discharge channel is always the same as the width of the receiving port. Then, multiple partitions 13 and the opening plate 14 cooperate with each other to form multiple discharge channels at the discharge port 28, and only the discharge channels located on the left side of the intercepting plate 7 are used, while the discharge channels located on the right side of the intercepting plate 7 do not work. At this time, align the leftmost receiving port with the left discharge channel, and the remaining discharge channels will also be aligned with the receiving ports accordingly. At this time, when the materials are pushed out by the pushing cloth 27, the materials will evenly fall into multiple receiving ports through the discharge channels, thus improving the uniformity of material receiving. At the same time, it also avoids the situation that when the materials are discharged from the discharge port 28, the materials fall into the gap between adjacent two receiving ports, which is beneficial to the subsequent distribution and transfer work of the materials.

[0034] In this embodiment, such as Figure 10 、 Figure 11As shown, an anti-jamming component is also provided on the partition plate 13; The anti-jamming component includes a second cylinder 31 fixedly connected to one side of the upper end of the partition plate 13. The piston end of the second cylinder 31 is fixedly connected with a mounting block 32. A groove plate 34 is rotatably arranged on one side of the mounting block 32. An anti-jamming rod 36 is slidably connected to the chute of the groove plate 34.

[0035] One side of the mounting block 32 is fixedly connected with a seventh motor 37. The output end of the seventh motor 37 is fixedly connected to the groove plate 34. The upper end of the anti-jamming rod 36 is threadedly connected with a fourth threaded rod 35. Both ends of the fourth threaded rod 35 are rotatably arranged on the groove plate 34. One end of the groove plate 34 is fixedly connected with a sixth motor 33. The output end of the sixth motor 33 is fixedly connected to one end of the fourth threaded rod 35.

[0036] Specifically, in the above embodiment, although the width of the discharge channel can be adjusted by driving the opening plate 14 to rotate, however, the opening plate 14 will be at different angles due to the adjustment, so the opening plate 14 is not parallel to the moving track of the material. As a result, when the material is discharged through the discharge channel, the material is likely to get stuck at the opening plate 14, affecting normal material receiving; Therefore, to solve this problem, when this embodiment is in use, according to the angle of the opening plate 14, the seventh motor 37 is used to drive the groove plate 34 to rotate, so that the groove plate 34 is parallel to the opening plate 14. And the anti-jamming rod 36 is attached to the surface of one side of the opening plate 14. When the material is discharged through the discharge channel, the seventh motor 37 drives the fourth threaded rod 35 to rotate, so that the anti-jamming rod 36 moves along the surface of one side of the opening plate 14, then the material in contact with the opening plate 14 can be pushed, thus promoting the movement of the material in contact with the opening plate 14, avoiding the situation that the material is stuck at the opening plate 14 when discharged through the discharge channel due to the non-parallel movement track between the opening plate 14 and the material, affecting normal material receiving. At the same time, the second cylinder 31 drives the mounting block 32 to move, which can adjust the distance between the anti-jamming rod 36 and the opening plate 14, thereby expanding the movement range of the anti-jamming rod 36 and further improving the anti-jamming effect.

[0037] In this embodiment, as Figure 3 shown, a collection box 6 is fixedly connected to one end of the frame 1. A vibrating screen 5 is also provided at one end of the frame 1. The collection box 6 is located below the screen of the vibrating screen 5.

[0038] Specifically, before the material is placed on the conveyor belt 2, the material is first placed on the screen of the vibrating screen 5. During the process that the material slides down along the screen, the vibrating screen 5 generates vibration to screen out the impurities in the material and fall them into the collection box 6. The vibrating screen 5 is an existing screening device, and no more details will be described here. Then, after the material falls on the conveyor belt 2, the impurities in it have been removed, thereby improving the purity and quality of the material, which is beneficial to the subsequent processing work.

[0039] Working principle: Place bulk materials such as coal or ore to be conveyed at one end of the conveyor belt 2. According to the position of the receiving equipment, start the motors 8 on both sides simultaneously. Drive the winding and unwinding rollers 9 to rotate through the motors 8 on both sides. Since the same baffle cloth 4 is wound around the two winding and unwinding rollers 9, the two winding and unwinding rollers 9 cooperate with each other to adjust the position of the discharge port 28 on the baffle cloth 4. Then, drive the threaded rod 29 to rotate through the motor 39, so that the cutting plate 7 slides on the baffle 3 to adjust the position of the cutting plate 7, making one side edge of the cutting plate 7 coincide with one side edge of the discharge port 28. Then, drive the conveyor belt 2 to operate. The conveyor belt 2 drives the material to move towards the discharge port 28. When the material is blocked by the cutting plate 7, the motor 30 drives the threaded rod 18 to rotate, causing the threaded block 19 to move horizontally on the cutting plate 7, making the pushing cloth 27 approach the discharge port 28. Since the initial position of the pushing cloth 27 is at the edge of the baffle 3, the pushing cloth 27 can push the material within the range of its unreeled part towards the discharge port 28, and the material can be unloaded through the discharge port 28. Thus, during the material conveying process, the baffle 3 and the baffle cloth 4 can be used to block the material to prevent the material from falling off the conveyor belt 2 in advance, and the discharge orientation of the material can be controlled by adjusting the position of the discharge port 28, thereby meeting different discharge requirements; after the pushing cloth 27 completes a pushing action, the cylinder 20 drives the lifting plate 21 to rise, making the bottom of the pushing cloth 27 away from the conveyor belt 2, and then the pushing cloth 27 is reset horizontally. When the pushing cloth 27 is at the edge of the baffle 3, the pushing cloth 27 descends again to fit the conveyor belt 2, which can avoid the situation that when the pushing cloth 27 is reset, it will push the subsequent material reaching the cutting plate 7 towards the baffle 3, resulting in the subsequent abnormal operation of the pushing cloth 27. Then, repeat the above operations to continuously unload the material; although the discharge orientation of the material can be controlled in the above way, the discharge range of the material is the same as the size of the discharge port 28. In some cases, the receiving port area of the receiving equipment is smaller than the discharge port 28, which will cause the material to fall outside the receiving port when the receiving equipment picks up the material, thus affecting normal material receiving. And when the discharge port 28 is set too small to avoid the above problem, it will affect the discharge speed. Therefore, to solve this problem, first adjust the position of the cutting plate 7 within the range of the discharge port 28, and then according to the length between the cutting plate 7 and one side edge of the discharge port 28, and record this length as the preset length. Start the motor 25 and the motor 24 simultaneously. The motor 25 drives the winding and unwinding roller 26 to rotate, and the motor 24 drives the gear 23 to rotate, making the rack bar 22 move horizontally. The rack bar 22 drives the end of the pushing cloth 27 to move, and at the same time, in cooperation with the winding and unwinding of the pushing cloth 27, the length of the unreeled part of the pushing cloth 27 is the same as the above preset length. Then, when the pushing cloth 27 pushes the material, it will only push the material within the preset length range, thus realizing the control of the material discharge range and avoiding the situation that when the receiving port area of the receiving equipment is smaller than the discharge port 28, the material falls outside the receiving port when the receiving equipment picks up the material, affecting normal material receiving. In addition,The discharging range depends on the area of the material receiving opening of the material receiving device, which maximally ensures the discharging speed. Moreover, since the length of the unreeled part of the pushing cloth 27 is equal to the preset length, when the pushing cloth 27 moves horizontally, the situation where the pushing cloth 27 and the baffle cloth 4 are damaged due to the material being squeezed between the pushing cloth 27 and the baffle cloth 4 will not occur, which is beneficial to extending the service life of the pushing cloth 27 and the baffle cloth 4. After the positions of the discharging opening 28 and the cutting plate 7 are determined, the motor two 10 is used to drive the threaded rod one 11 to rotate, so that the mounting rod 12 slides on one side of the frame 1, and the position of the leftmost partition 13 is adjusted to make the edge of this partition 13 align with the left edge of the discharging opening 28. The space between adjacent two partitions 13 serves as the discharging channel. By driving the opening plate 14 to rotate with the motor eight 38, the distance between the end of the opening plate 14 and the partition 13 is adjusted, and then the width of the discharging channel can be adjusted to be equal to the width of the material receiving opening. Then, according to the spacing of multiple equidistantly arranged material receiving openings, the electric push rod 15 is used to drive the rightmost partition 13 to slide on the mounting rod 12. Then, with the cooperation of the connecting rod one 16 and the connecting rod two 17, the distance between adjacent two partitions 13 can be adjusted. At the same time, the opening plate 14 continuously rotates to adapt to the change in the distance between adjacent partitions 13, so that the width of the discharging channel is always the same as the width of the material receiving opening. Then, multiple partitions 13 and the opening plate 14 cooperate with each other to form multiple discharging channels at the discharging opening 28, and only the discharging channels located on the left side of the cutting plate 7 are used, while the discharging channels located on the right side of the cutting plate 7 do not work. At this time, align the leftmost material receiving opening with the left discharging channel, and the other discharging channels will also be aligned with the material receiving openings accordingly. At this time, the material is pushed out by the pushing cloth 27, and the material evenly falls into multiple material receiving openings through the discharging channel, thereby improving the evenness of material receiving. At the same time, it also avoids the situation where the material falls into the gap between adjacent two material receiving openings when the material is discharged through the discharging opening 28, which is beneficial to the subsequent distribution and transfer of the material. According to the angle of the opening plate 14, the motor seven 37 is used to drive the groove plate 34 to rotate, so that the groove plate 34 is parallel to the opening plate 14. Moreover, the anti-jamming rod 36 is attached to one side surface of the opening plate 14. When the material is discharged through the discharging channel, the motor seven 37 drives the threaded rod four 35 to rotate, so that the anti-jamming rod 36 moves along one side surface of the opening plate 14, and then the material in contact with the opening plate 14 can be pushed, thereby promoting the movement of the material in contact with the opening plate 14. This avoids the situation where the material is stuck at the opening plate 14 when the material is discharged through the discharging channel because the opening plate 14 is not parallel to the movement track of the material, which affects normal material receiving. At the same time, the cylinder two 31 drives the mounting block 32 to move, and the distance between the anti-jamming rod 36 and the opening plate 14 can be adjusted, thereby expanding the movement range of the anti-jamming rod 36 and further improving the anti-jamming effect. Before the material is placed on the conveyor belt 2, the material is first placed on the screen of the vibrating screen 5. During the process of the material sliding down along the screen, the vibrating screen 5 vibrates to screen out the impurities in the material and make them fall into the collection box 6. The vibrating screen 5 is an existing screening device and will not be elaborated here. Then, after the material falls on the conveyor belt 2, the impurities in it have been removed.Thereby, the purity and quality of the material are improved, which is beneficial to subsequent processing work.
