Flexible oil pointer for mining coal cutter

Abstract

The invention discloses a flexible oil pointer for a mining coal cutter. The flexible oil pointer comprises an oil pointer body, a semi-hollow screw, a transparent rubber hose and a color foamed plastic sphere, wherein the oil pointer body is fixedly communicated with an oil tank body wall through the semi-hollow screw, a seal washer is arranged on an abutting joint surface between the oil pointer and the semi-hollow screw and between the oil pointer and the wall of the body of the oil tank, the transparent rubber hose is matched with an oil outlet of the oil pointer, and the color foamed plastic sphere is placed inside the transparent rubber hose; and the oil pointer is sunken into the wall of the body of the oil tank. The flexible oil pointer can be conveniently installed in a narrow space and read, and is free of danger of burst of the oil pointer due to too high temperature; in addition, for the oil pointer is placed inside the wall of the body of the oil tank, the oil pointer can be prevented from being collided and damaged by foreign objects; and as a result, the difficulty of maintenance of equipment and accidents caused by insufficiency of lubricating oil can be reduced.

Description

technical field [0001] The invention relates to an oil standard for a mining coal shearer, in particular to a flexible oil standard for a mining coal shearer. Background technique [0002] At present, there are two kinds of oil marks commonly used for drum shearers, one is a long oil mark and the other is a round oil mark. [0003] Affected by the downhole environment and the equipment itself, the temperature of the gear oil is relatively high, and the accidents that the plexiglass of the long oil standard is scalded and broken often occur. And in the design process of thin coal seam, extremely thin coal seam shearer, be subjected to the limitation of equipment structure and size, often do not have suitable position to place long type oil mark. [0004] Although the round oil scale is small in size and easy to place, it is difficult to read the indication of the oil scale in a relatively narrow space with thin or extremely thin coal seams, and it cannot accurately reflect t...

And in the design process of thin coal seam and extremely thin coal seam shearer, due to the limitation of equipment structure and size, there is often no suitable place to place long oil standard

[0004] Although the round oil scale is small in size and easy to place, it is difficult to read the indication of the oil scale in a relatively narrow space with thin coal seams and extremely thin coal seams, and it cannot accurately reflect the amount of oil in the tank
