The invention discloses a hydraulic traction coal mining machine. The hydraulic traction coal mining machine comprises a traction part, a motor part, a cutting part, and a coal loading part; the motorpart is arranged between the traction part and the cutting part; the coal loading part is arranged on one side of the cutting part opposite to the motor part; the cutting part comprises a cutting boxassembly; a cutting first shaft assembly, a cutting second shaft assembly, a cutting third shaft assembly, a cutting fourth shaft assembly, a cutting fifth shaft assembly, and a clutch assembly are arranged in the cutting box assembly; the cutting first shaft assembly, the cutting second shaft assembly, the cutting third shaft assembly, the cutting fourth shaft assembly, the cutting fifth shaft assembly, and the clutch assembly are arranged in the cutting box assembly, so that a spiral roller assembly and the coal loading part can be driven to rotate at the same time, coal is cut off from coal body (coal breaking), and is loaded onto a working face conveyer (coal loading); the whole machine strength is high; the reliability is high; the adaptability is high; and requirements on matching equipment are low.
Description
technical field [0001] The invention belongs to the technical field of mining or quarrying equipment, in particular to a hydraulic traction shearer. Background technique [0002] Shearer is one of the main equipment of fully mechanized mining equipment. The coal shearer evolved from the coal cutter. 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. The coal shearer is one of the important equipments to realize the mechanization and modernization of coal mine production. Its working principle is: on the longwall coal mining face, the coal is broken down from the coal body by the working mechanism (broken coal) and loaded into the working face for transportation. machine (charging coal). The shearer walks (tracts) according to the set traction speed, so that the coal breaking and co...
