Coal mining face excavator and coal mining device using the excavator

Abstract

The invention provides a coal mining face excavating loader and a coal mining device using the excavating loader. The coal mining device comprises a conveying chute and the coal mining face excavating loader, wherein the excavating loader comprises a base which is arranged on a coal mining face and can move along the movement direction of the conveying chute; the base is fixedly provided with an excavating bucket assembly for excavating a coal layer and filling coal into the conveying chute; the excavating bucket assembly comprises an excavating bucket bracket hinged on the base and an excavating bucket hinged to the excavating bucket bracket; the base is provided with a bracket driving oil cylinder for driving the excavating bucket bracket to move; and the excavating bucket bracket is provided with an excavating bucket driving oil cylinder for driving the excavating bucket to move. The whole structure of the coal mining device provided by the invention is simple and the blasting and coal falling operation does not need to be carried out; the working environment is effectively improved, and coal falling and coal loading mechanical work can be realized; the labor intensity of workers is reduced; and the coal mining device is particularly applicable to 'three-soft' coal layers or medium and small-sized mine mechanical operation with geological conditions similar with the 'three-soft' coal layers.

Description

technical field [0001] The invention relates to a digging machine for a coal mining face and a coal mining device using the digging machine. Background technique [0002] At present, when mining coal in small and medium-sized coal mines, most of the coal is mined by blasting and dropping coal. This production process is referred to as blast mining. Blast mining technology has been widely used because of its low requirements on coal seam storage conditions and strong adaptability. When carrying out blast mining operations, blast holes are drilled on the coal seam first, and the coal is mined by blasting. Then the workers enter the roadway to clean up the fallen coal, and then put the coal into the chute and transport it out. [0003] When mining coal, the first thing to pay attention to is safe production. For small and medium-sized coal mines, it is necessary to pay special attention to the safety support of the roof of the working face. However, when blasting is used, the ...
