Abstract

The invention relates to the technical field of coal cutting equipment, and particularly discloses an efficient coal cutter. The efficient coal cutter comprises a coal cutter body and guiding slidingshoes supporting the coal cutter body; the guiding sliding shoes comprise sliding shoes bodies and abrasion-resistant pieces detachably connected to the sliding shoes bodies; the abrasion-resistant pieces are attached to pin rows, and detecting holes are formed in the abrasion-resistant pieces; one ends of the detecting holes are connected with air pressure switches, and the air pressure switchesand the detecting holes can form closed spaces; the air pressure in the closed spaces is higher than the atmospheric pressure, and the air pressure switches are electrically connected with a controller on the coal cutter; and the air pressure switches are used for emitting an alarm signal to the controller when it is detected that the air pressure is lower than a set value. According to the efficient coal cutter, through cooperation of the air pressure switches and the detecting holes, alarming after the abrasion-resistant pieces are seriously abraded and then generate cracks is achieved, andthe problem of troublesome replacement after breaking of the guiding sliding shoes is avoided.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a high-efficiency coal mining machine. Background technique [0002] The coal shearer is a large and complex system integrating machinery, electricity and hydraulic pressure. The working environment is harsh. If there is a failure, it will cause the interruption of the entire coal mining face and cause huge economic losses. With the development of the coal industry, the shearer has more and more functions, and its own structure and composition are becoming more and more complex, so the reasons for the failure are also complicated. [0003] The shearer is generally composed of a traction unit, a cutting unit, a travel box, a rocker arm and an electric control unit, etc. The bottom of the travel box is equipped with a guide shoe and a support shoe. The traction unit mainly includes a traction motor and a traction transmission system. The main work The principle is th...
