Problems solved by technology

At present, there is a certain distance between the last hydraulic support in the upwind roadway and the side of the upwind roadway in the fully mechanized mining face. The gap between the side of the road is affected by the mine pressure. The side of the upwind road and the roof of the coal seam are easily deformed, and then the filling air bag is squeezed. Because the filling air bag lacks the pressure relief function, the filling air bag is prone to damage. At the same time, the filling air bag is inflated Most of them are elliptical, and the stacking stability is not enough

Abstract

The invention provides a filling device for coal mining, comprising a filling air bag and an inflation nozzle installed on one side of the filling air bag. A rubber sleeve and a second rubber sleeve, the outer side of the second rubber sleeve is provided with an external thread cylinder, a cylindrical body is sleeved on the external thread cylinder, and a fixing ring is fixed on the side of the cylinder body away from the internal thread , the side of the fixing ring facing away from the inner thread is provided with a thin iron sheet, and the side of the fixing ring facing the thin iron sheet is installed with a magnet block. Compared with the prior art, the present invention has the following beneficial effects: it has the following advantages It can prevent the filling airbag from being squeezed and damaged, and also achieve the purpose of stably stacking the filling airbag.

Description

technical field [0001] The invention relates to a filling device for coal mining in a coal mine, which belongs to the field of coal mining equipment. Background technique [0002] Comprehensive mechanized coal mining refers to the entire production process of the coal mining face, including coal breaking, coal loading, coal transportation, support, goaf treatment, mining roadway transportation, and excavation. At present, there is a certain distance between the last hydraulic support in the upwind roadway and the side of the upwind roadway in the fully mechanized mining face. The gap between the side of the road is affected by the mine pressure. The side of the upwind road and the roof of the coal seam are easily deformed, and then the filling air bag is squeezed. Because the filling air bag lacks the pressure relief function, the filling air bag is prone to damage. At the same time, the filling air bag is inflated Most of them are oval in shape, and the stacking stability ...
