Slope adjusting device for middle trough of fully-mechanized scraper conveyor for thin seam

Abstract

The invention relates to a slope adjusting device for a middle trough of a fully-mechanized scraper conveyer for a thin seam, comprising a middle trough pushing and connecting device 8, a base lifting device, a supporting mechanism, and the like, wherein the middle trough pushing and connecting device 8 is arranged at the side of a middle trough baffle; except for an original middle trough pushing lug plate 3, the middle trough pushing and connecting device 8 is additionally provided with a middle articulating piece and an outside articulating piece; the base lifting device mainly comprises a cylinder 9; the supporting mechanism mainly comprises a supporting beam 10; the cylinder is positioned in the middle of the middle trough pushing lug plate; the body of the cylinder is articulated on the middle articulating piece of the middle trough pushing and connecting device; the head of a piston rod of the cylinder is articulated with the middle articulating piece in the middle of the front part of the supporting beam directly or through a connecting rod; and front ends at two sides of the supporting beam 10 extend forwards and are then articulated to the outside articulating piece of the middle trough pushing and connecting device. The slope adjusting device improves the bottom rolling capacity of pushing the middle trough by controlling the cylinder to stretch to adjust the height of the middle trough baffle side of the scraper conveyer and well solves the problem that the middle trough of the pushing scraper conveyer of a fully-mechanized working face of the thin seam frequently drifts.

Description

technical field [0001] The utility model relates to a pushing device between a hydraulic support of a fully mechanized mining face and a scraper conveyor, in particular to a fully mechanized mining face of a thin coal seam, which can adjust the side height of the middle groove of the scraper conveyor to increase the height of the push middle groove Slope adjustment device in the middle of the scraper conveyor for thin coal seam fully mechanized mining with bottom rolling capacity. Background technique [0002] Due to the short body of the thin coal seam shearer and the small diameter of the drum, the coal loading effect of the shearer drum is poor when the thin coal seam is mined. In the actual production process, the coal must be shoveled into the scraper conveyor by relying on the coal shovel plate in the middle groove of the scraper conveyor. Due to the small undercover capacity of the thin coal seam shearer, the working face is often undulating, and the hydraulic suppor...
