Design of Cutting Coal and Wireless Tracking Dust Removal System of Shearer in Fully Mechanized Mining Face
In order to effectively solve the problems of hard installation,broken wire and cumbersome maintenance among the equipment of the coal cutting tracking and dust removal system of fully mechanized face shearer,a coal cutting tracking and spraying system based on wireless communication is designed.The general structure of the system is described,the design principle of the shearer positioning transmitter and positioning receiver is introduced,and the hardware design,software design and low power design process of the spray control box are emphasized.The simulation system was set up in the laboratory,and the spray function experiment was carried out.The results showed that wireless communication was adopted between the devices of the system,which reduced the intermediate line connection,and the installation and maintenance were simple.The system could control the opening and closing of the electric ball valve according to the set system spray parameters,and realize the spray dust removal near the shearer drum.
