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 acylinder 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 onthe 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 frontpart 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 heightof 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 involves the push device between the hydraulic stent and the scraper conveyor of the comprehensive mining of the comprehensive mining, especially for the height of the middle slot of the middle slot of the middle slot on the middle of the slot push of the comprehensive mining of the coal seam comprehensive mining, adjustableThe thin coal seam comprehensive mixing plate conveyor in the bottom of the bottom slot is adjusted. Background technique [0002] Due to the short coal seam coal mining machine, the diameter of the drum is small, the coal selemers have poor effects when the coal seam is mining.In the actual production process, the coal shovel in the middle of the scraper conveyor must be relying on the middle part of the scraper conveyor to put the coal shovel into the scraper conveyor.Due to the small underworld volume of the coal seam coal mining machine, the working surface is often ups and downs, and the phenomenon of fluttering of...
