Embodiment Construction

[0030] Among them: 1. Middle tank body, 2. Rib plate, 3. Left rail seat assembly, 4. Bending plate assembly, 5. Right rail seat assembly, 6 Lap joint plate, 7. Pin rail, 8. Cylindrical pin, 9. Limiting pin, 10, cable groove, 11, "∑" type shovel plate groove side, 12 "∑" type baffle plate groove side, 13, middle plate, 14, base plate.

[0031]

[0032] The invention provides a middle groove of a scraper conveyor, such as Figure 1~3 As shown, the middle tank body 1 is a cast-welded bottom sealing structure, including: "∑" type shoveling side 11, "Σ" type baffle side 12, middle plate 13, and bottom plate 14. The middle 13 plate is located above the bottom plate 14 , and provided with intervals, the "∑" type shovel side is pivotally connected to the left side of the middle plate 13 and the bottom plate 14, and the "Σ" type baffle side is pivotally connected to the right side of the middle plate 13 and the bottom plate 14. The "∑" type shovel side 11 and the "∑" type baffle si...

Abstract

The invention relates to the technical field of mining extremely thick coal seams of an underground coal mine, in particular to a middle trough and scraper conveyor applied to full-seam mining in extremely thick coal seams. The middle trough comprises a middle trough body, a bend plate assembly, a left rail base assembly, a right rail base assembly, a rib plate and a lap jointed plate. The middle trough body is of a cast-weld sealing bottom structure and comprises an M-shaped cast shovel plate ledge, an M-shaped cast baffle ledge, a middle plate and a bottom plate formed by the adoption of a welding technology. By the adoption of the cast-weld sealing bottom middle trough and a right horizontal type pin rail structure, spatial layout of a high-power coal mining machine can be met, and three-machine mating for full-seam mining in the extremely thick coal seams is benefitted. The width in the middle trough ranges from 1450 mm to 1600 mm, the length ranges from 2050 mm to 2400 mm, the height of the ledges ranges from 435 mm to 465 mm, the area of the middle coal pass fracture surface is larger than 2 m<2>, the conveying ability of the conveyor surpasses 7000 tons per hour, the conveying problem of full-seam mining in the extremely thick coal seams of 8.3-9.2 m is solved, and the utilization rate of coal recovery is increased. Meanwhile, the middle trough and the scraper conveyor fill up the blank at home and abroad and have great significance in future development of full-seam mining in the extremely thick coal seams.

Description

technical field [0001] The invention relates to the technical field of ultra-thick coal seam mining in underground coal mines, in particular to a central trough and a scraper conveyor for full-height mining of extra-thick coal seams at one time. The central trough and scraper conveyor are suitable for 8.3-9.2 m The thick coal seam mining full-height coal mining technology. Background technique [0002] So far, top-coal caving is used for extra-thick coal seams above 8.3m. Due to the low rate of coal recovery and high risk of top-coal caving mining, the development of full-height equipment for one-time mining has become a new topic in the field of fully mechanized coal mining equipment. The present invention can satisfy the space layout of the ultra-high-power coal mining machine by adopting the middle groove of the cast-welded bottom seal and the horizontal pin-rail structure, which is beneficial to the three-machine matching of the full-height mining of the extra-thick coa...
