Opencast coal mining machine capable of effectively crushing coal briquettes and usage thereof

Abstract

The invention provides an opencast coal mining machine capable of effectively crushing coal briquettes and usage thereof, which relate to the technical field of machinery. The opencast coal mining machine comprises a coal mining machine body, a coal-crushing roller power box is arranged on one side of a coal-crushing roller, the coal-crushing roller power box is connected with a main power case through a connecting arm, a hydraulic piston rod is arranged on the bottom of the coal-crushing roller power box, fan-shaped stirring blocks are arranged on the surface of a coal-shoveling bucket, a stirring tank is arranged at one side of the fan-shaped stirring blocks, a conveyer belt is arranged at one side of the stirring tank, a control room is electrically connected with the main power case, the coal-crushing roller power box, the fan-shaped stirring blocks, a rotary motor and travelling pedrails are all electrically connected with the control room, and the hydraulic piston rod is electrically connected with the coal-crushing roller power box. The opencast coal mining machine is an opencast coal mining machine which can effectively crush coal briquettes; since the stirring tank is arranged, coal briquettes can be rolled and crushed by stirring disks in the stirring tank, consequently, the opencast coal mining machine can effectively ensure that coal briquette particles getting intoa coal outlet passage are fine, and thereby coal briquette blockage is prevented; and the invention has high 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...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a surface coal mining machine for effectively pulverizing coal blocks and its use method, which solves the problem that the existing surface coal mining machines in the market mentioned above often have some problems when mining coal. The coal block is relatively large. When it is transported to the coal outlet channel through the conveyor belt, the coal block is too large to block the coal outlet channel and affect the work efficiency.
