Technical Field

[0001] The utility model relates to a trough box of a heavy scraper feeder for open-pit coal mines, which is used for transferring materials between open-pit mine trucks and long-distance belt conveyors. Background Art

[0002] With the continuous excavation and mining of open-pit coal mines, the problem of transferring materials between open-pit mine trucks and long-distance belt conveyors has become increasingly prominent. The bottleneck of the equipment structure needs to be broken through. It is necessary to develop a transfer equipment suitable for the open-pit coal mine environment, and a trough box of a heavy scraper feeder for open-pit mines is an important part of it. Summary of the Invention

[0003] The purpose of the utility model is to solve the problem of transferring materials between open-pit mine trucks and long-distance belt conveyors, and develop a transfer feeding equipment suitable for the open-pit coal mine environment. A trough box of a heavy scraper feeder for open-pit mines is an important part of it.

[0004] The technical solution of the utility model consists of plate A1, rib plate F2, lifting ring 3, plate C4, side plate 5, rib plate H6, bottom plate 7, cylindrical pin 8, middle plate 9, plate C10, wing plate 11, side blocking plate 12, positioning plate 13, elastic washer 14, bolt 15, wear-resistant guide rail 16, scraper 17, and circular chain 18. Plate A1, rib plate F2, lifting ring 3, plate B4, side plate 5, rib plate H6, bottom plate 7, cylindrical pin 8, middle plate 9, plate C10, and wing plate 11 are welded together as a whole and named the trough body; the side blocking plate 12 and the positioning plate 13 are welded together as a whole and named the side cover plate; the side cover plate is blocked on the side plate 5 and fixed by the elastic washer 14 and the bolt 15; the wear-resistant guide rail 16 is welded on the bottom plate 7 along the length direction of the trough body to support and hold the scraper 17 to prevent wear on the bottom plate 7.

[0005] Furthermore, the scraper 17 and the circular chain 18 run along the J direction on the middle plate 9, which belongs to the material transportation layer; the scraper 17 and the circular chain 18 run in the reverse direction of the J direction on the wear-resistant guide rail 16, which belongs to the empty running return chain layer; setting the J direction as the front, the gap between the end of the scraper 17 and the side plate 5 is small in the front and large in the back, with an oblique angle of about 4°. Hard lumps of materials are squeezed into the gap and are easily discharged backward; the E pick tip can sometimes quickly break up the lumps; the materials flow along the R plow-shaped arc surface in the F direction to the middle of the trough body, which is convenient for transportation; the D surface of the wing plate 11 is an inclined surface that is 9° upward. The lumps of materials remaining under the wing plate 11 can easily slide out under the push of the scraper 17; the plate 10 prevents the materials from entering the dead corner and plays a role in cleaning the root.

[0006] The beneficial effects of the utility model are:

[0007] To solve the bottleneck problem of the transfer between open-pit mine trucks and long-distance belt conveyors, develop a transfer feeding device suitable for the open-pit coal mine environment, and provide a trough box for the heavy-duty scraper feeder in the open-pit mine that is easy to maintain, observe, and wear-resistant.

[0008] The technical solution of the present invention will be described in detail below in conjunction with the drawings and specific embodiments. Description of the Drawings

Specific Embodiments

[0017] As Figure 1 、 2 shown, Plate A1, Rib plate F2, Suspension ring 3, Plate B4, Side plate 5, Rib plate H6, Bottom plate 7, Cylindrical pin 8, Middle plate 9, Plate C10, and Wing plate 11 are welded together as a whole and named the trough body; as Figure 4 shown, Side plug plate 12 and Positioning plate 13 are welded together as a whole and named the side cover plate; as Figure 1 shown, the side cover plate is blocked on the side plate 5 and fixed by Elastic washer 14 and Bolt 15; as Figure 2 、3 As shown, the wear-resistant guide rail 16 is welded to the bottom plate 7 along the length direction of the trough body, supporting the scraper 17 and preventing wear on the bottom plate 7.

[0018] Furthermore, as Figure 3 、 5 shown, the scraper 17 and the endless chain 18 run along the J direction on the middle plate 9, belonging to the material transportation layer; the scraper 17 and the endless chain 18 run in the reverse direction along the J direction on the wear-resistant guide rail 16, belonging to the empty running return chain layer; as Figure 6 shown, setting the J direction as the front, the gap between the end of the scraper 17 and the side plate 5 is small at the front and large at the back, with an inclined angle of about 4°. Hard lumps of material are squeezed into the gap and are easily discharged backward (; The E pick tip can sometimes quickly break up lumps; The material surges along the R-shaped plow surface to the middle of the trough body along the F direction, facilitating transportation; as Figure 7 shown, the D surface of the wing plate 11 is an inclined surface that is 9° upward. The lumps of material remaining below the wing plate 11 can easily slide out under the push of the scraper 17; The plate 10 prevents the material from entering the dead corner and plays a role in cleaning the root.
