Disclosed is an automatic pushing-rolling control method for a thin coal seam. A hydraulic support electrohydraulic control system with the automatic following function is adopted. A hydraulic support set is composed of a plurality of hydraulic supports. An inclination adjusting jack is designed on each hydraulic support so as to be linked with pushing-rolling actions. The three functions of inclination adjustment, linkage and multi-wheel pushing-rolling can be selected to be enabled according to site condition execution. The linkage function of the inclination adjustment action and the pushing-rolling action is achieved, and the problems of bottom pricking and floating rolling of a scraper conveyor in the thin coal seam environment are effectively solved; the front bottom pricking function of the scraper conveyor is achieved through inclination adjustment before pushing-rolling, and the problems of float coal removal and scraper conveyor floating are solved; the multi-wheel pushing-rolling action strategy is achieved, coal mining and coal transportation flow are balanced, and the problem that mining and transportation are not matched is solved; the multi-wheel pushing-rolling strategy is applied to automatic following, the problem that full-automatic mining cannot be achieved due to the fact that mining and transportation are not matched in the following process is solved, and automatic mining of the thin coal seam is achieved.

An electronic device with a battery buckle mechanism includes a body, an elastic buckle mechanism and a battery. The main body has a receiving groove, and the elastic buckle mechanism includes a first guiding surface and a second guiding surface connected adjacently, and the first guiding surface and the second guiding surface are located in the receiving groove and are connected to the receiving groove. There is a gap between the side walls. When the battery is put into the accommodating slot, the battery pushes against the first guiding surface, so that the first guiding surface and the second guiding surface move closer to the side wall of the accommodating slot. When the battery leaves the accommodating slot, the battery pushes against The two guide surfaces make the first guide surface and the second guide surface away from the side wall of the accommodating groove.

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.
