Description

Technical Field

[0002] The coal mining machine is a large and complex system integrating mechanical, electrical and hydraulic systems. The working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, causing huge economic losses. The machine is used to cut the bottom groove in the coal mining working face of the slow-sloping thin coal seam and extremely thin composite coal seam in general medium and small mines to achieve the purpose of cutting the groove and dropping the coal. The rocker arm is a large equipment for coal mining in coal mines.

[0003] For example, Chinese patent publication number: CN106602795A discloses a dual-motor drive structure for a coal mining machine rocker arm, which is characterized by: comprising two small-volume asynchronous motors arranged on both sides of the output shaft, the torque shaft of each asynchronous motor drives the output shaft through a planetary gear, and the output shaft drives the cutting part through a reduction mechanism; the cooling water paths of the cooling structures of the two asynchronous motors are connected in series.

[0004] The following problems exist in the prior art: when the existing coal mining machine rocker arm is mining, the space in the underground environment is relatively small, the air is not flowing, and the dust is relatively large. When the equipment is used for a long time, a large amount of high temperature environment will be generated on the surface of the equipment. The equipment will cool it down internally, but due to the problem of a lot of dust, while cooling it down, the dust in the outside air will penetrate into the roller inside the rocker arm rotor. As time goes by, the ore dust will cause friction on the rotating shaft, so that the inside of the rotating rod will be damaged. Utility Model Content
