A cooler for coal mining equipment

Abstract

The invention discloses a cooler for coal mining equipment, belonging to the technical field of coal mining equipment, comprising a rocker arm casing, a gear cavity and a heat conduction cavity. There is a heat conduction cavity, the inner wall of the heat conduction cavity is arranged with a number of fin plates, and the fin plate is also arranged with a guide tube, and the several guide tubes are connected end to end in turn, and the oil outlet and the oil return nozzle are arranged in the gear cavity. The two sides are connected to the oil storage chamber, and the transmission mechanism is arranged on one side of the rocker arm housing to drive the reciprocating motion of the piston in the oil storage chamber to circulate the gear oil. The present invention is independently arranged in the rocker arm housing. The heat transfer component and the pump oil component can make the gear oil circulate continuously in the gear cavity, and conduct non-contact heat exchange with cooling water after heat absorption, so as to circulate the gear oil to dissipate heat and cool down, and heat up the The cooling water is used for the cooling and dust suppression of the coal cutter head, realizing the circulating cooling of the coal mining equipment.

Description

technical field [0001] The invention belongs to the technical field of coal mining equipment, in particular to a cooler for coal mining equipment. Background technique [0002] Shearer is one of the most important equipment in fully mechanized coal mining equipment. Mechanized coal mining can reduce physical labor, improve safety, and achieve the purpose of high output, high efficiency and low consumption. Commonly used coal mining machinery is usually shaken by the shearer. The arm, the left and right walking parts, the left and right walking boxes, the shearer casing, the left and right cutting parts, the electric control part, the left and right traction parts and the shearer drum, etc., also include a double gear pump, a planetary reducer, a shaft Two-axis, three-axis, four-axis, five-axis and other wearing parts. [0003] Because the coal mining environment is closed and the coal mining and cutting work on the coal seam for a long time, the rocker arm and the cutting h...

AI Technical Summary

Problems solved by technology

[0003] Due to the closed coal mining environment and the coal mining and cutting work on the coal seam for a long time, the rocker arm and the cutting head will accumulate a lot of heat, and the high temperature environment will also increase the wear and tear of the transmission gear shaft. The water mist cools the rocker arm and the cutter head, but its cooling effect on the internal gear shaft is limited, and the heat conduction efficiency is low
