Description

Technical Field

[0001] The utility model relates to the technical field of coal mining machines, in particular to a lubricating device for a high-power electric traction coal mining machine with a thin coal seam. Background Art

[0002] A coal mining machine is a coal mining machine that uses a working mechanism to break coal from the coal body (breaking coal) and load it into the working face conveyor (loading coal) at the longwall coal mining face. Electric traction is a form of rail transportation traction power that uses electric energy as power. An electric traction coal mining machine is a coal mining machine that uses electric energy as power for rail transportation traction.

[0003] The electric traction coal shearer is the core equipment of the fully mechanized mining face. The electric traction coal shearer has good traction characteristics, good dynamic performance, sensitive response, reliable operation, high efficiency, long service life, and complete detection and display systems. It can adapt to the gently inclined longwall fully mechanized mining face in medium-hard coal seams and can operate safely in coal mines with explosive mixed gases, gas and coal dust.

[0004] A coal mining machine with automatic centralized lubrication function is disclosed in the patent document with announcement number CN202012347U. The device is easy to install and has low investment cost. It does not require any changes to the structure of the coal mining machine and will not cause any adverse effects on the working performance of the coal mining machine. It is easy to use and operate. The controller can start and stop the electric dry oil pump to achieve the purpose of automatic centralized lubrication of multiple transmission parts on the coal mining machine. The oil filling is fully automated, which greatly reduces the workload of coal mining machine maintenance workers. Since the working cycle sequence of the progressive distributor is in a progressive action, it can ensure that the lubricating grease from the electric dry oil pump is quantitatively delivered to each lubrication point in sequence. The use effect is good. Since the lubricating grease is directly delivered to each transmission part on the coal mining machine through the main oil supply line and the branch oil supply line, it can effectively ensure that the delivered grease will not be contaminated by coal dust, etc., which greatly improves the cleanliness of the grease and the service life of the transmission parts. At the same time, since the lubricating grease is directly delivered to the transmission parts to be lubricated through the pipeline, the amount of grease waste is very small.
