The invention discloses a cooling device for a rocker arm of a coal mining machine and the coal mining machine. The cooling device comprises a connecting shell, an inner gear ring, a first flow guidehole and guide pipes, wherein the connecting shell is connected with a rocker arm shell of the coal mining machine and is arranged close to a cutting part transmission gear; the inner gear ring is located in the connecting shell, and a first water channel is formed between the inner gear ring and the inner wall of the connecting shell; a first flow guide hole is formed in the inner gear ring and communicates with the first water channel; and the guide pipes communicate with the first flow guide hole and are connected with a circulating pump located on the outer side of the rocker arm shell, and the circulating pump enables cooling water to circulate among the first water channel, the first flow guide hole and the guide pipes so as to cool the rocker arm of the coal mining machine. According to the cooling device, the first flow guide hole communicating with the guide pipes is formed in the inner gear ring, so that the first water channel, the first flow guide hole and the guide pipes can be in communication, then the circulating pump connected with the guide pipes can circulate cooling water among the first water channel, the first flow guide hole and the guide pipes, and therefore, the cutting part transmission gear can be cooled.
Description
technical field [0001] The invention belongs to the technical field of coal shearers, and in particular relates to a cooling device for a rocker arm of a coal shearer and a coal shearer. Background technique [0002] The transmission gear of the cutting part on the rocker arm of the coal mining machine will generate a lot of heat during long-term work, which is sealed in the cavity and difficult to discharge. And in the prior art, generally adopt natural cooling or adopt the mode of internal perforation to do cooling channel to cool the rocker arm of coal mining machine. The natural cooling method, when used for a long time, will cause the internal temperature of the gearbox to rise, resulting in poor lubrication, which will affect the life of the transmission gear. The method of internally opening the circulating water channel will not only increase the processing workload of the rocker arm, but also weaken the strength of the shaft and shell of the rocker arm to a certain...
