[0002] With the continuous mining of coal resources, there are more and more application requirements for thin coal seam shearers. At present, the existing airborne coal shearers have some large electronic devices built in the fuselage. Due to the low space for thin coal seam mining, Limits the use of airborne shearers
At the same time, when the shearer is working, the shearer vibrates greatly, and the display and other components are easily damaged by the shock.
[0003] The existing coal shearer uses the control core wire in the power cable of the main power supply to transmit the control signal, which is prone to breakage of the control core wire, and it is difficult to check the breakpoint on site

The invention relates to a non-airborne electric control device of low seam mining machine. Built-in electronic devices of an existing coal cutter are liable to break, large in height and are unsuitable for mining thin seams. The non-airborne electric control device of low seam mining machine comprises an airborne electric control part, a non-airborne electric control part and a plurality of power carrier transceivers, wherein each power carrier transceiver is composed of a transmitting module and a receiving module, the receiving module is arranged in the non-airborne electric control part, the transmitting module is arranged in the airborne electric control part and is used for detecting the starting and stopping signals of the low seam mining machine, detecting a conveyor blocking signal, receiving a signal from a remote control receiving module, a motor temperature signal and a gas alarm signal and transmitting the signals to the corresponding transmitting module by cutting a main cable, and the transmitting module transfers the signals to a main control part. The non-airborne electric control device disclosed by the invention is used for reducing the breakage rate of electric elements and decreasing the height of the low seam mining machine and is suitable for fully-mechanized coal mining work of various coal seams and particularly suitable for the fully-mechanized coal mining work of low seams.
