Open-pit coal mining machine capable of effectively crushing coal briquettes

Abstract

The invention provides an open-pit coal mining machine capable of effectively crushing coal briquettes, and relates to the technical field of engineering machinery. The open-pit coal mining machine comprises a working platform; a control chamber is arranged at the top of the working platform; a coal pressing roller power box is arranged on one side of a coal pressing roller; the coal pressing roller power box is connected with a main power machine box through a connecting arm; a hydraulic piston rod is arranged at the bottom of the coal pressing roller power box; a fan-shaped stirring block isarranged on the surface of a coal bucket; a stirring box is arranged on one side of the fan-shaped stirring block; a conveyor belt is arranged on one side of the stirring box; the device is an open-pit coal mining machine capable of effectively crushing coal briquettes and is provided with the stirring box; the coal briquettes are rolled and crushed through a stirring disc inside the stirring box, so that fine particle of the coal briquettes entering a coal outlet channel can be effectively guaranteed, and the blockage of the coal briquettes which causes the problem that the working efficiency is low can be avoided; and the open-pit coal mining machine capable of effectively crushing coal briquettes is provided. The open-pit coal mining machine capable of effectively crushing coal briquettes is reasonable in design, simple in structure, capable of being safe, reliable, convenient to use, easy to maintain, good in popularization and application value.

Description

technical field [0001] The invention relates to a coal shearer, in particular to an open-pit coal shearer for effectively crushing coal blocks. Background technique [0002] The coal shearer is a large complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. Shearer is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve high output, high efficiency, and low consumption. Coal shearer is divided into four types: sawing type, planing type, drilling type and milling type: coal shearer is a large and complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. The interruption of coal mining will cause huge economic losses. With the development...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a surface coal mining machine that effectively crushes coal blocks. However, in the current market, when the existing surface coal mining machines are mining coal, some coal blocks are often large, and when passing through the conveyor belt When transported to the coal outlet channel, the coal block will be too large to block the coal outlet channel, which will affect the work efficiency and waste time, which is very inconvenient to use
