Description

Technical Field

[0001] This invention relates to a shuttle conveyor belt machine, and more particularly to a high-efficiency sealing and dust removal device for use in shuttle conveyor belt machines. Background Technology

[0002] Shuttle belt conveyors are mainly used in mining, power, metallurgy, and grain industries. During the material descent process in these fields, dust is generated at the discharge point, causing environmental pollution, material loss, and increased cleaning workload for workers. Furthermore, while the shuttle belt conveyor's hopper moves, the position of the upper funnel is fixed. This causes interference between the top cover of the guide chute and the chute's chute duct. Currently, the solution to this interference problem is to create a long rectangular opening in the top cover of the guide chute, which leads to difficulties in dust removal.

[0003] To solve the aforementioned dust removal problem, one approach is to completely enclose the mobile conveyor belt for dust removal. However, this approach requires significant investment in enclosure and requires a large volume of air for dust removal, and the dust removal effect is unsatisfactory, so it is rarely used. Another approach is to use mobile ventilation ducts for dust removal. This approach requires slightly less investment than the first approach, but the enclosed space between the two unloading points is still relatively large, resulting in a low cost-effectiveness ratio, and it is not widely used in actual production.

[0004] Therefore, with increasingly stringent environmental protection requirements, there is an urgent need for a cost-effective and more efficient sealing and dust removal solution. Summary of the Invention

[0005] To address the aforementioned technical problems, embodiments of the present invention provide a high-efficiency sealing and dust removal device for shuttle conveyor belt machines. The specific technical solution is as follows:

The second tensioning device is located on the side of the second stop position away from the first stop position and is connected to one end of the second flexible sealing strip, the other end of which is connected to the right side of the chute. The second flexible sealing strip covers the right side of the shuttle conveyor belt machine and the second elongated hole. The first and second flexible sealing strips cover the travel distance of the shuttle conveyor belt machine between the first and second stop positions.

[0007] In a first possible implementation of the first aspect, it further includes: a scratch-resistant sealing elastic element disposed around the first elongated hole, and both the first flexible sealing strip and the second flexible sealing strip covering the scratch-resistant sealing elastic element.

[0008] In a second possible implementation of the first aspect, at least one of the left and right sides of the chute is provided with a spout, and the spout is fixedly connected to the other end of the corresponding first flexible sealing strip or the other end of the second flexible sealing strip.

[0009] In conjunction with the second possible implementation of the first aspect, in the third possible implementation of the first aspect, a dust removal and air intake is provided on the chute.

[0010] In conjunction with the second possible implementation of the first aspect, in the fourth possible implementation of the first aspect, the spout is fixed to the roof beam by a hanger.

[0011] In the fifth possible implementation of the first aspect, a first roller group is provided on the left side of the shuttle conveyor, and the middle section of the first flexible sealing belt passes through each roller of the first roller group in sequence to cover the left side of the shuttle conveyor.

[0014] In this embodiment of the invention, an elongated hole is provided at the top of the feed chute of the shuttle conveyor, thus solving the interference problem between the top cover plate of the feed chute and the chute pipe of the funnel. Simultaneously, the invention provides a first tensioning device and a second tensioning device on the outer sides of the first and second parking positions, respectively. A first flexible sealing strip and a second flexible sealing strip cover the travel distance of the shuttle conveyor between the first and second parking positions and the elongated hole at the top of the feed chute.

[0024] Please see Figure 1 and Figure 2 This is a schematic diagram of a high-efficiency sealing and dust removal device applied to a shuttle conveyor belt machine according to an embodiment of the present invention. Figure 2 yes Figure 1A cross-sectional view along line AA; as shown in the figure, the high-efficiency sealing and dust removal device 100 is applied to the shuttle conveyor belt 1 to seal the travel distance between the first parking position S1 and the second parking position S2 of the shuttle conveyor belt 1. In this embodiment, the first parking position S1 is located on the left and the second parking position S2 is located on the right. The high-efficiency sealing and dust removal device 100 in this embodiment includes a first tensioning device 2, a first flexible sealing strip 3, a second tensioning device 4, and a second flexible sealing strip 5. The top of the guide chute 11 of the shuttle conveyor belt 1 is provided with an elongated hole, which is divided into a first elongated hole 111 and a second elongated hole 112 by a chute 12, as shown... Figure 1 As shown, the first elongated hole 111 is located on the left side of the chute 12, and the second elongated hole 112 is located on the right side of the chute 12. By setting the first elongated hole 111 and the second elongated hole 112 on the top of the guide chute 11 of the shuttle conveyor 1, the interference problem between the top cover plate of the guide chute 11 and the chute pipe of the funnel can be solved.

[0025] The first tensioning device 2 is located on the side of the first parking space S1 away from the second parking space S2, such as... Figure 1 As shown, the first tensioning device 2 is located on the left side of the first parking space S1. The first tensioning device 2 is connected to one end of the first flexible sealing strip 3, and the other end of the first flexible sealing strip 3 is connected to the left side of the chute 12. The first flexible sealing strip 3 covers the left side of the shuttle tape machine 1 and the first elongated hole 111. The tension of the first flexible sealing strip 3 is adjusted by the first tensioning device 2 to ensure the sealing of the first flexible sealing strip 3 covering the left side of the shuttle tape machine 1 and the first elongated hole 111. The first tensioning device 2 can be a cylinder, and the first flexible sealing strip 3 can be made of tape, canvas, or other flexible materials, but the invention is not limited to these.

[0026] In this embodiment, a first roller group 13 is arranged on the left side of the shuttle conveyor belt 1, and the middle section of the first flexible sealing belt 3 passes through each roller of the first roller group 13 in sequence to cover the left side of the shuttle conveyor belt 1. Specifically, as Figure 1 As shown, the first roller group 13 includes three first rollers 131, which are located at the upper left, middle and lower left ends of the shuttle belt machine 1, respectively. The first flexible sealing belt 3 and the chute 12 are connected to the upper surface of the first rollers 131 at the upper left and middle ends of the shuttle belt machine 1, and then pass around the first roller 131 at the lower left end of the shuttle belt machine 1 to connect with the first tensioning device 2.

[0027] The second tensioning device 4 is located on the side of the second parking space S2 away from the first parking space S1, such as... Figure 1As shown, the second tensioning device 4 is located on the right side of the second parking space S2. The second tensioning device 4 is connected to one end of the second flexible sealing strip 5, and the other end of the second flexible sealing strip 5 is connected to the right side of the chute 12. The second flexible sealing strip 5 covers the right side of the shuttle conveyor belt 1 and the second elongated hole 112. The tension of the second flexible sealing strip 5 is adjusted by the second tensioning device 4 to ensure the sealing of the second flexible sealing strip 5 over the right side of the shuttle conveyor belt 1 and the second elongated hole 112. The second tensioning device 4 can be a cylinder, and the second flexible sealing strip 5 can be made of tape, canvas, or other flexible materials, but the invention is not limited to these.

[0028] In this embodiment, a second roller group 14 is provided on the right side of the shuttle conveyor belt 1, and the middle section of the second flexible sealing belt 5 passes through each roller of the second roller group 14 in sequence to cover the right side of the shuttle conveyor belt 1. Specifically, as Figure 1 As shown, the second roller group 14 includes three second rollers 141, which are located at the upper, middle and lower right ends of the shuttle belt machine 1, respectively. The second flexible sealing belt 5 and the chute 12 are connected to the upper surface of the second rollers 141 at the upper and middle right ends of the shuttle belt machine 1, and then pass around the second roller 141 at the lower right end of the shuttle belt machine 1 to connect with the second tensioning device 4.

[0029] When the shuttle conveyor belt 1 moves from the first parking position S1 to the second parking position S2, the length of the first flexible sealing belt 3 adjacent to the ground becomes longer, the length on the guide chute 11 becomes shorter, and the total length of the first flexible sealing belt 3 remains unchanged. At the same time, the length of the second flexible sealing belt 5 adjacent to the ground becomes shorter, the length of the guide chute 11 becomes longer, and the total length of the second flexible sealing belt 5 remains unchanged.

[0030] In this embodiment, the first flexible sealing strip 3 and the second flexible sealing strip 5 cover the travel distance of the shuttle conveyor 1 between the first parking position S1 and the second parking position S2, as well as the first elongated hole 111 and the second elongated hole 112. This achieves sealing of the shuttle conveyor 1 with relatively low investment and high cost-effectiveness, making it suitable for widespread application in actual production. Furthermore, when the first flexible sealing strip 3 and the second flexible sealing strip 5 are loose, their tightness can be adjusted by the first tensioning device 2 and the second tensioning device 4 provided on the outside of the first parking position S1 and the second parking position S2, ensuring the sealing performance of the shuttle conveyor 1 and the first elongated hole 111 and the second elongated hole 112.

[0031] Please see Figure 3 See also Figure 2 , Figure 3 yes Figure 2A partial enlarged view of point P; as shown in the figure, the high-efficiency sealing dust removal device 100 also includes a scratch-resistant sealing elastic element 6. The scratch-resistant sealing elastic element 6 is disposed around the elongated hole, surrounding the first elongated hole 111 and the second elongated hole 112. The first flexible sealing strip 3 and the second flexible sealing strip 5 cover the scratch-resistant sealing elastic element 6 to prevent the first flexible sealing strip 3 from being scratched by the guide groove 11 when the shuttle belt conveyor 1 moves. The main body material of the scratch-resistant sealing elastic element 6 can be rubber, but the present invention is not limited thereto.

[0032] See also Figures 1 to 3 As shown, at least one of the left and right sides of the chute 12 is provided with a nozzle 121. The nozzle 121 is fixedly connected to the other end of the corresponding first flexible sealing strip 3 or the other end of the second flexible sealing strip 5. The nozzle 121 is arranged along the material running direction on the shuttle conveyor 1. Since the shuttle conveyor 1 in this embodiment runs in both directions, nozzles 121 are provided on both sides of the chute 12. The nozzle 121 is fixed to the roof beam S3 by a hanger 123. A dust removal suction port 122 is also provided on the nozzle 121, which can be located on the side or top surface of the nozzle 121.

[0033] In summary, this invention provides a high-efficiency sealing and dust removal device for shuttle conveyor belt machines. By providing an elongated hole at the top of the feed chute of the shuttle conveyor belt machine, the interference problem between the top cover plate of the feed chute and the chute's chute is solved. Simultaneously, this invention provides a first tensioning device and a second tensioning device on the outer sides of the first and second parking positions, respectively, and uses a first flexible sealing strip and a second flexible sealing strip to cover the travel distance of the shuttle conveyor belt between the first and second parking positions and the elongated hole at the top of the feed chute. This achieves sealing of the shuttle conveyor belt machine with relatively low investment and high cost-effectiveness, making it widely applicable in actual production.
