[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention discloses a mining conveyor with a screening function. A discharge position control assembly utilizes a baffle and a cloth to block material during conveying, preventing it from prematurely falling off the conveyor belt. Furthermore, by adjusting the position of the discharge port, the material discharge position is controlled to meet varying discharge requirements. Furthermore, as material is discharged through the discharge port, the discharge range is controlled to prevent the receiving device from receiving material outside the receiving port when receiving it, potentially affecting normal material delivery, due to the receiving device's smaller receiving port area. Furthermore, the discharge range is appropriately set based on the receiving device's receiving port area, maximizing discharge speed while ensuring that material accurately enters the receiving device. Because the unwound portion of the pusher cloth is the same length as the preset length, material is prevented from being squeezed between the pusher cloth and the cloth during transverse movement, potentially damaging the pusher cloth and the cloth. This helps extend the service life of the pusher cloth and the cloth.

[0022] 2. The mining conveying device with a screening function described in the present invention utilizes a multi-channel discharging assembly to form multiple discharging channels with the cooperation of multiple partitions and opening plates, and when multiple receiving ports of the same specifications and equidistant distribution are used to receive materials, the spacing and specifications of the multiple discharging channels can be adjusted according to the number and width of the receiving ports, as well as the spacing between two adjacent receiving ports, so that the multiple discharging channels correspond to the multiple receiving ports. When the material is pushed out by the push cloth, the material will fall evenly into the multiple receiving ports through the discharging channel, thereby improving the uniformity of the material receiving. At the same time, it also avoids the situation where the material falls into the gap between two adjacent receiving ports when the material is discharged through the discharging port, which is beneficial to the subsequent distribution and transfer of the material.

[0023] 3. The mining conveying device with a screening function described in the present invention utilizes an anti-stuck component to align the trough plate with the opening plate according to the angle of the opening plate, while also allowing the anti-stuck rod to contact the surface of one side of the opening plate. When the material is discharged through the discharge channel, the anti-stuck rod will move along the surface of one side of the opening plate, pushing the material in contact with the opening plate, thereby causing the contacted material to move, thereby preventing the material from being stuck at the opening plate during discharge due to the opening plate being non-parallel to the moving trajectory, thereby affecting normal material connection. In addition, the second cylinder drives the installation block to move, which can adjust the distance between the anti-stuck rod and the opening plate, expand the movement range of the anti-stuck rod, and enhance the anti-stuck effect.

[0024] 4. The mining conveying device with screening function described in the present invention places the material on the screen of the vibrating screen before placing it on the conveyor belt. As the material slides down along the screen, the vibrating screen vibrates, screening out impurities in the material and dropping them into a collection box. After the material falls on the conveyor belt, the impurities in the material have been removed, thereby improving the purity and quality of the material and facilitating subsequent processing work.

[0038] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Please refer to Figures 1-11 The present invention provides a technical solution: a mining conveying device with a screening function, comprising a frame 1, a conveyor belt 2 is provided on the frame 1, and a discharge direction control component is also provided on the frame 1;

[0040] The discharging direction control component includes a baffle 3 fixedly connected to one side of the upper end of the frame 1, and a retracting roller 9 is rotatably provided on both sides of the upper end of the frame 1. The same baffle cloth 4 is wrapped around the two retracting rollers 9, and a discharging port 28 is provided on one side of the baffle cloth 4. A material cutting plate 7 is slidably connected to the slide groove on one side of the baffle 3, and a threaded block 19 is slidably connected to one side of the material cutting plate 7. A cylinder 20 is fixedly connected to one side of the upper end face of the threaded block 19, and a lifting plate 21 is fixedly connected to the piston end of the cylinder 20. A retracting roller 26 is rotatably provided on one side of the lifting plate 21, and a pushing cloth 27 is wrapped around the retracting roller 26. One end of the pushing cloth 27 is fixedly connected to a rack rod 22, and the rack rod 22 is slidably connected to the lifting plate 21.

[0041] In this embodiment, Figures 1-8 As shown, motor 18 is fixedly connected to both sides of the upper end of the frame 1, and the output end of motor 8 is fixedly connected to one end of the retractable roller 19.

[0042] One side of the cutting plate 7 is threadedly connected to a threaded rod three 29, both ends of the threaded rod three 29 are rotatably set on the baffle 3, one end of the baffle 3 is fixedly connected to a motor nine 39, and the output end of the motor nine 39 is fixedly connected to one end of the threaded rod three 29.

[0043] One end of the threaded block 19 is threadedly connected to the threaded rod 2 18, and both ends of the threaded rod 2 18 are rotatably set on the cutting plate 7. One side of the cutting plate 7 is fixedly connected to the motor 5 30, and the output end of the motor 5 30 is fixedly connected to one end of the threaded rod 2 18. One side of the lifting plate 21 is fixedly connected to the motor 4 25, and the output end of the motor 4 25 is fixedly connected to one end of the retracting roller 2 26. A gear 23 is rotatably set on one side of the upper end of the lifting plate 21, and the gear 23 is engaged with the tooth block on the rack rod 22. A motor 3 24 is fixedly connected to one side of the upper end of the lifting plate 21, and the output end of the motor 3 24 is fixedly connected to the gear 23.

[0044] Specifically, when the existing mining belt conveyor is in use, the material to be conveyed is placed at one end of the conveyor belt 2, and the material moves to the other end of the conveyor belt 2 and then falls, thereby realizing the transportation of the material. At the same time, the materials on both sides of the conveyor belt 2 can be blocked during the transportation process to prevent the materials from falling. However, in some cases, the material receiving equipment 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 the non-end position of the conveyor belt 2. In the existing technology, the material can only be unloaded from the end of the conveyor belt 2, so it is difficult to meet different unloading requirements.

[0045] When the material is blocked by the cutting plate 7, the motor 5 30 drives the threaded rod 2 18 to rotate, so that the threaded block 19 moves horizontally on the cutting plate 7, so that the pushing cloth 27 is close to the discharging port 28. The material that has not been rolled up is pushed to the discharge port 28 by the pusher 27, so that the material can be discharged through the discharge port 28. In this way, the baffle 3 and the baffle 4 can be used to block the material during the material transportation process, so as to prevent the material from falling off the conveyor belt 2 in advance. The discharge port 28 can also be used to control the discharge direction of the material, thereby meeting different discharge requirements. When the pusher 27 completes one pushing action, the cylinder 1 20 drives the lifting plate 21 to rise, so that the bottom of the pusher 27 is away from the conveyor belt 2, and then the pusher 27 is reset horizontally. When the pusher 27 is at the edge of the baffle 3, the pusher 27 is lowered again to fit the conveyor belt 2, which can avoid the pusher 27 from pushing the subsequent material reaching the cutting plate 7 to the baffle 3 when the pusher 27 is reset, thereby causing the pusher 27 to fail to work normally. Then repeat the above operation to achieve continuous unloading of the material.

[0046] Although the material discharge direction can be controlled by the above method, the material discharge range is the same size as the discharge port 28. In some cases, the receiving port area of ​​the receiving device is smaller than the discharge port 28. This will cause the material to fall outside the receiving port when the receiving device receives the material, thereby affecting the normal material receiving. In order to avoid the above problem, setting the discharge port 28 too small will affect the unloading speed. Therefore, in order 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 the edge of one side of the discharge port 28, and calculate this length as the preset length, start motor four 25 and motor three 24 at the same time, motor four 25 drives the retracting roller two 26 to rotate, and motor three 24 drives the gear 23 to rotate, so that the rack rod 22 moves horizontally, and the rack rod 22 drives the end of the push cloth 27 The material is then pushed by the push cloth 27 so that it can be retracted and extended to allow the material to pass through the bag 22. The push cloth 27 is moved horizontally and the length of the unwound portion of the push cloth 27 is the same as the preset length. When the push cloth 27 pushes the material, it will only push the material within the preset length range, thereby realizing the control of the material unloading range and avoiding the situation where the receiving port area of ​​the receiving equipment is smaller than the discharge port 28 and the material falls outside the receiving port when the receiving equipment receives the material, thereby affecting the normal material receiving. In addition, the discharge range depends on the receiving port area of ​​the receiving equipment, which guarantees the unloading speed to the greatest extent. Moreover, since the length of the unwound portion of the push cloth 27 is equal to the preset length, the material will not be squeezed between the push cloth 27 and the blocking cloth 4 when the push cloth 27 moves horizontally, thereby causing damage to the push cloth 27 and the blocking cloth 4. This is beneficial to extending the service life of the push cloth 27 and the blocking cloth 4.

[0047] In this embodiment, Figure 4 、 Figures 8-11 As shown, the frame 1 is also provided with a multi-channel discharge assembly;

[0048] The multi-channel discharging assembly includes a mounting rod 12 slidably connected to one side of the frame 1, and a plurality of partitions 13 are arranged equidistantly laterally on the upper side of the mounting rod 12. The leftmost partition 13 is fixedly connected to the mounting rod 12, and the remaining partitions 13 are slidably connected to the mounting rod 12. An opening plate 14 is rotatably provided on one side of the partition 13, and one side of the partition 13 is flush with the surface of one side of the cloth 4.

[0049] One side of the lower end of the mounting rod 12 is threadedly connected to a threaded rod 11, and both ends of the threaded rod 11 are rotatably set on the frame 1. One side of the frame 1 is fixedly connected to a motor 2 10, and the output end of the motor 2 10 is fixedly connected to one end of the threaded rod 11.

[0050] Two connecting rods 16 are rotatably provided on the upper ends of the leftmost and rightmost partitions 13, and two connecting rods 2 17 are rotatably provided on the upper ends of the remaining partitions 13. One end of connecting rod 16 is rotatably connected to one end of connecting rod 2 17, and the ends of two adjacent connecting rods 2 17 are rotatably connected. An electric push rod 15 is fixedly connected to one side of the upper end of the mounting rod 12, and the piston end of the electric push rod 15 is fixedly connected to one end of the rightmost partition 13. A motor 8 38 is fixedly connected to one side of the partition 13, and the output end of the motor 8 38 is fixedly connected to one end of the opening plate 14.

[0051] Specifically, in the above embodiment, although the control of the unloading position and the unloading range can be achieved, in some cases, multiple receiving ports will be used to receive the material at the same time to achieve the distribution of the material. In addition, in order to improve the uniformity of receiving the material and to facilitate the transfer of the material to other processes, multiple receiving ports of the same specifications will be used, and these receiving ports will be equidistantly distributed. This setting is more common in mining production. If the material is discharged directly from the discharge port 28, it will be difficult for the material to fall evenly in different receiving ports, and the material will easily fall in the gap between two adjacent receiving ports, thereby affecting the distribution of the material and the subsequent transfer work.

[0052] Therefore, in order to solve the above problem, when the present embodiment is in use, after the positions of the discharge port 28 and the cutting plate 7 are determined, the motor 2 10 is used to drive the threaded rod 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 so that the edge of this partition 13 is aligned with the left edge of the discharge port 28, and the space between the two adjacent partitions 13 serves as a discharge channel. The motor 8 38 drives the opening plate 14 to rotate, and the distance between the end of the opening plate 14 and the partition 13 is adjusted, so that the width of the discharge channel can be adjusted so that this width is equal to the width of the receiving port. Then, according to the spacing of multiple equidistant receiving ports, the electric push rod 15 is used to drive the rightmost partition 13 to slide on the mounting rod 12, and the two adjacent partitions 1 can be adjusted with the cooperation of the connecting rod 16 and the connecting rod 2 17. 3, and at the same time, the opening plate 14 continues to rotate to adapt to the change in the distance between adjacent partitions 13, so that the width of the discharge channel is always the same as the width of the material receiving port, then multiple partitions 13 and opening plates 14 cooperate with each other to form multiple discharge channels at the discharge port 28, and only the discharge channel located on the left side of the cutting plate 7 is used, and the discharge channel located on the right side of the cutting plate 7 is not working. At this time, align the leftmost material receiving port with the discharge channel on the left, and the remaining discharge channels are also aligned with the material receiving port. At this time, the material is pushed out by the push cloth 27, and the material falls evenly into multiple material receiving ports through the discharge channel, thereby improving the uniformity of the material receiving. At the same time, it also avoids the situation where the material falls into the gap between the two adjacent material receiving ports when the material is discharged through the discharge port 28, which is beneficial to the subsequent distribution and transfer of the material.

[0053] In this embodiment, Figure 10 、Figure 11 As shown, an anti-stuck component is also provided on the partition 13;

[0054] The anti-stuck component includes a cylinder 2 31 fixedly connected to one side of the upper end of the partition 13, and the piston end of the cylinder 2 31 is fixedly connected to a mounting block 32. A slot plate 34 is rotatably provided on one side of the mounting block 32, and an anti-stuck rod 36 is slidably connected to the sliding groove of the slot plate 34.

[0055] A motor seven 37 is fixedly connected to one side of the mounting block 32, and the output end of the motor seven 37 is fixedly connected to the slot plate 34. The upper end of the anti-stuck rod 36 is threadedly connected to a threaded rod four 35, and both ends of the threaded rod four 35 are rotatably set on the slot plate 34. One end of the slot plate 34 is fixedly connected to a motor six 33, and the output end of the motor six 33 is fixedly connected to one end of the threaded rod four 35.

[0056] Specifically, in the above embodiment, although the width of the discharge channel can be adjusted by driving the opening plate 14 to rotate, the opening plate 14 will be at different angles due to the adjustment, and the opening plate 14 and the moving trajectory of the material are not parallel, resulting in the material being easily stuck at the opening plate 14 when being discharged through the discharge channel, affecting normal material reception;

[0057] Therefore, in order to solve this problem, when this embodiment is in use, the motor seven 37 is used to drive the slot plate 34 to rotate according to the angle of the opening plate 14, so that the slot plate 34 is parallel to the opening plate 14, and the anti-stuck rod 36 is in contact with the surface of one side of the opening plate 14. When the material is discharged through the discharge channel, the motor seven 37 drives the threaded rod four 35 to rotate, so that the anti-stuck rod 36 moves along the surface of one side of the opening plate 14, which can push the material in contact with the opening plate 14, thereby prompting the material in contact with the opening plate 14 to move, avoiding the situation where the material is stuck at the opening plate 14 when discharged through the discharge channel due to the opening plate 14 being not parallel to the material movement trajectory, thereby affecting the normal material connection. At the same time, the cylinder two 31 drives the mounting block 32 to move, and the distance between the anti-stuck rod 36 and the opening plate 14 can be adjusted, thereby expanding the moving range of the anti-stuck rod 36 and further improving the anti-stuck effect.

[0058] In this embodiment, Figure 3 As shown, a collecting box 6 is fixedly connected to one end of the frame 1 , and a vibrating screen 5 is also provided at one end of the frame 1 , and the collecting box 6 is located below the screen of the vibrating screen 5 .

[0059] Specifically, before the material is placed on the conveyor belt 2, the material is first placed on the screen of the vibrating screen 5. While the material slides down along the screen, the vibrating screen 5 vibrates, screens out impurities in the material, and drops them into the collection box 6. The vibrating screen 5 is an existing screening equipment and will not be described in detail here. After the material falls on the conveyor belt 2, the impurities therein have been removed, thereby improving the purity and quality of the material, which is beneficial to subsequent processing work.

[0060] Working principle: put the bulk materials such as coal or ore to be transported at one end of the conveyor belt 2, and start the motors 18 on both sides at the same time according to the position of the material receiving equipment, and drive the reel-in roller 19 to rotate through the motors 18 on both sides. Since the same blocking cloth 4 is wound around the two reel-in rollers 9, the two reel-in rollers 9 cooperate with each other to adjust the position of the discharge port 28 on the blocking cloth 4, and then drive the threaded rod 3 29 to rotate by the motor 9 39 to make the cutting plate 7 slide on the baffle 3, adjust the position of the cutting plate 7 so that the edge of one side of the cutting plate 7 coincides with the edge of the one side of the discharge port 28, and then drive the conveyor belt 2 to operate, and the conveyor belt 2 drives the material to move to the discharge port 28. When the material is blocked by the cutting plate 7, the motor 5 30 drives the threaded rod 2 18 to rotate. The pattern block 19 moves horizontally on the material cutting plate 7, so that 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 material within the unwound part to the discharge port 28, and the material can be unloaded through the discharge port 28. Therefore, during the material transportation process, the baffle 3 and the blocking cloth 4 can be used to block the material to prevent the material from falling from the conveyor belt 2 in advance, and the unloading direction of the material can be controlled by adjusting the position of the discharge port 28, thereby meeting different unloading requirements; when the pushing cloth 27 completes a pushing action, the cylinder 20 drives the lifting plate 21 to rise, so that the bottom of the pushing cloth 27 is 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 is pushed. The cloth 27 is lowered again to fit with the conveyor belt 2, which can prevent the material that has subsequently arrived at the cutting plate 7 from being pushed to the baffle 3 when the pushing cloth 27 is reset, thereby causing the pushing cloth 27 to fail to work normally. Then, the above operation can be repeated to achieve continuous unloading of the material. Although the unloading direction of the material can be controlled by the above method, 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 material receiving device is smaller than the discharge port 28, which will cause the material to fall outside the receiving port when the material receiving device receives the material, thereby affecting the normal material receiving. In order to avoid the above problem, setting the discharge port 28 too small will affect the unloading speed. Therefore, in order to solve this problem, the cutting plate 7 is first adjusted to the range of the discharge port 28. The position within the range is determined according to the length between the cutting plate 7 and the edge of one side of the discharge port 28, and this length is counted as the preset length. At the same time, the motor 4 25 and the motor 3 24 are started, and the motor 4 25 drives the retracting roller 26 to rotate, and the motor 3 24 drives the gear 23 to rotate, so that the rack bar 22 moves laterally, and the rack bar 22 drives the end of the pushing cloth 27 to move, and at the same time cooperates with the retraction and extension of the pushing cloth 27 to make the length of the unwound part of the pushing cloth 27 the same as the above-mentioned preset length. When the pushing cloth 27 pushes the material, it will only push the material within the preset length range, thereby realizing the control of the material unloading range, avoiding the situation that the material receiving port area of ​​the receiving device is smaller than the discharge port 28, and the material falls outside the receiving port when the receiving device receives the material, affecting the normal material receiving. In addition,The discharge range depends on the receiving port area of ​​the receiving equipment, which ensures the unloading speed to the greatest extent. In addition, since the length of the unwound part of the push cloth 27 is equal to the preset length, the push cloth 27 will not be squeezed between the push cloth 27 and the blocking cloth 4 when the push cloth 27 moves horizontally, thereby causing damage to the push cloth 27 and the blocking cloth 4, which is beneficial to extending the service life of the push cloth 27 and the blocking cloth 4. After the positions of the discharge port 28 and the cutting plate 7 are determined, the motor 2 10 is used to drive the threaded rod 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 so that the edge of this partition 13 is aligned with the left edge of the discharge port 28, and the space between the two adjacent partitions 13 serves as a discharge channel. The motor 8 38 is used to drive the opening plate 14 to rotate, and the distance between the end of the opening plate 14 and the partition 13 is adjusted. The width of the discharge channel can be adjusted so that this width is equal to the width of the receiving port. Then, according to the spacing of multiple equidistant receiving ports, the electric push rod 15 is used to drive the rightmost partition 13 to slide on the mounting rod 12. The distance between the two adjacent partitions 13 can be adjusted with the cooperation of the connecting rod 16 and the connecting rod 2 17. 4 continues to rotate to adapt to the change in the distance between adjacent partitions 13, so that the width of the discharge channel is always the same as the width of the material receiving port, then the 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 channel located on the left side of the cutting plate 7 is used, and the discharge channel located on the right side of the cutting plate 7 is not working. At this time, the leftmost material receiving port is aligned with the discharge channel on the left, and the remaining discharge channels are also aligned with the material receiving port. At this time, the material is pushed out by the push cloth 27, and the material falls evenly into the multiple material receiving ports through the discharge channel, thereby improving the uniformity of the material receiving. At the same time, it also avoids the situation where the material falls into the gap between two adjacent material receiving ports when being discharged through the discharge port 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 slot plate 34 to rotate so that the slot plate 34 is parallel to the opening plate 14, and the anti-stuck rod 36 is in contact with the surface of one side of the opening plate 14. When the material is discharged through the discharge channel, the motor seven 37 drives the threaded rod four 35 to rotate, so that the anti-stuck rod 36 moves along the surface of one side of the opening plate 14, which can push the material in contact with the opening plate 14, thereby prompting the material in contact with the opening plate 14 to move, avoiding the situation where the material is stuck at the opening plate 14 when discharged through the discharge channel due to the opening plate 14 being not parallel to the material movement trajectory, thereby affecting the normal material connection. At the same time, the cylinder two 31 drives the mounting block 32 to move, and the distance between the anti-stuck rod 36 and the opening plate 14 can be adjusted, thereby expanding the moving range of the anti-stuck rod 36 and further improving the anti-stuck effect. Before the material is placed on the conveyor belt 2, it is first placed on the screen of the vibrating screen 5. As the material slides down the screen, the vibrating screen 5 vibrates, screening out impurities in the material and dropping them into the collection box 6. The vibrating screen 5 is an existing screening device and will not be described in detail here. After the material falls on the conveyor belt 2, the impurities in the material have been removed.This improves the purity and quality of the material and is beneficial to subsequent processing.
