Cooler for coal mining equipment

Abstract

The invention discloses a coal mining equipment cooler, and belongs to the technical field of coal mining equipment, the coal mining equipment cooler comprises a rocker arm shell, gear cavities and a heat conduction cavity, a plurality of gear cavities are arranged in the rocker arm shell in an array mode, the heat conduction cavity is further arranged on one side of the rocker arm shell, a plurality of fin plates are arranged on the inner wall face of the heat conduction cavity in a staggered mode, and flow guide pipes are further arranged in the fin plates. The multiple flow guide pipes are sequentially communicated in an end-to-end mode, the oil outlet nozzle and the oil return nozzle are arranged on the two sides of the gear cavity and connected with the oil storage cavity, and the transmission mechanism is arranged on one side of the rocker arm shell and used for driving a piston in the oil storage cavity to do reciprocating motion so that gear oil can circularly flow. According to the gear oil cooling device, the gear oil can continuously and circularly flow in the gear cavity and is subjected to non-contact heat exchange with the cooling water after absorbing heat, so that the gear oil circularly dissipates heat and is cooled, and the cooling water after absorbing heat is used for cooling and dust suppression of a coal mining tool bit, so that circulating cooling of coal mining equipment is realized.

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 mining equipment in coal mines. Mechanized coal mining can reduce physical labor, improve safety, and achieve high output, high efficiency, and low consumption. Commonly used coal mining machinery is usually driven by a shearer. Arm, left and right travel parts, left and right travel boxes, shearer casing, left and right cutting parts, electric control part, left and right traction parts and shearer drums, etc., also includes double gear pump, planetary reducer, one shaft Two-axis, three-axis, four-axis, five-axis and other wearing parts. [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 hi...

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
