Embodiment Construction

[0017] like figure 1 and figure 2 Shown, the present invention comprises middle plate, bottom plate 7, the baffle stand plate 4 that is positioned at middle plate both sides, the shovel stand plate 8 that is positioned at the both sides of bottom plate 7 and middle plate and bottom plate 7, is positioned at the shovel stand plate 8 outsides Shovel coal plate 9, above-mentioned shovel vertical board 8 is flat plate. During manufacture, the present invention adopts a forged and welded structure, and all components do not adopt cast products; the structure is simple, easy to manufacture, the contact specific pressure is small, and it is wear-resistant.

[0018] The middle plate is a double-layer structure, including the live middle plate 5 and the lower middle plate 6. The joints of the middle plates adopt a W-shaped structure, which can sacrifice part of the wear of the middle plates to protect most of the joints from wear. The strength of the invention is guaranteed by the f...

Abstract

The invention discloses a forge welding double-middle-plate structure chute, and especially relates to a forge welding double-middle-plate structure chute which is high in working efficiency, small in abrasion and reliable in strength. In order to solve the technical problems that at present, a middle trough is low in cast-weld structure strength, poor in wear resistance, unstable in quality and limited in coal passing amount, the forge welding double-middle-plate structure chute comprises middle plates, a bottom plate, blocking vertical plates located on the two sides of the middle plates, shoveling vertical plates which are located on the two sides of the bottom plate and between the middle plates and the bottom plate, and ramp plates on the outer sides of the shoveling vertical plates. The shoveling vertical plates are flat plates. The forge welding double-middle-plate structure chute is large in coal passing amount, good in wear resistance, simple in structure and high in reliability.

Description

technical field [0001] The invention relates to a middle chute, in particular to a forged-welded double-middle plate structure chute with high working efficiency, less wear and reliable strength. Background technique [0002] At present, the structural type of the middle chute in China is mainly cast-welded structure, which has the following disadvantages: the strength of the chute decreases sharply with the wear of the middle plate; after the middle plate of the chute is worn, it can only be repaired by surfacing welding, which cannot be replaced. The amount of coal passing through the repair is limited; the wear resistance of the shovel plate of the chute is poor, and the shearer cannot be guaranteed to run in the predetermined state; the deflection (vertical and horizontal) of the chute is guaranteed by casting parts, but it is actually unreliable; The plate interface is severely worn; the shape of the bottom plate is not conducive to reducing the wear of the scraper and ...
