| Product usage The machine is mainly used for coal roadway , semi-coal rock roadway and soft rock roadway and tunnel excavation, which coal rock hardness f≤8 ,to help realize continuous cutting, loading and transportation operations.The maximum ]positioning cutting section can reach 22m2and the gradeability is ±18°.
1.The cutting part has internal and external spray, water leakage detection and protection functions, the cutting motor has thermal protection, the cutting head has a truncated cone shape, and the tooth holder is arranged in a spiral shape.The internal spray seal adopts the world's leading sealing surface compensation technology with independent property rights, which completely solves the problem of unreliability of internal spray in the tunneling machine; 2.The plate working surface adopts double-sided inclination angle, which is convenient for shipping and clearing the bottom. The overall design make machine strength is higher. The charging device is directly driven by the low-speed high-torque motor by the curved three-toothed star wheel; 3.The transport plane adopts middle double-chain, bilateral chain transport structure, which is suitable for the transport of coal, semi-coal rock and rock materials. The base plate is linear and the transport is smooth. The scraper transport is directly driven by two low-speed and high-torque hydraulic motors; 4.The walking part adopts a highly integrated structure of the reducer and the hydraulic motor,small volume and high reliability, and the tensioning device adopts a combined structure of the tightening cylinder and the adjusting pad; 5.The electrical system is controlled by programmable controller and has the functions of new comprehensive protection system module to realize protection, dynamic display of liquid crystal Chinese characters, thermal protection of cutting motor, automatic system fault detection and memory. 6.The pump and operating valve of the hydraulic system adopt the world advanced unit import from German , which has the functions of constant power control, pressure cutting and load sensitive. 7.The rear support device realizes the long span support and improves the machine stability. 8.The walking part adopts a highly integrated structure of the reducer and the hydraulic motor to solve the problem of host self-moving when driving up and down the mountain;The gear ring of reducer box drives the sprocket directly, the volume is small, the torque is big, the tightener device USES the tightener oil cylinder and the adjustment mat composite structure. 9.The strength can be effectively guaranteed by using the military enterprises' matching caterpillar plate, and it can be customized according to different geological conditions. 10.The electrical system is controlled by PLC programming, and the dynamic display of liquid crystal Chinese characters has the function of automatic fault detection and memory, as well as the functions of voltage loss, short-circuit, motor overload, temperature, leakage detection, high and low speed interlocking of cutting motor. 11.The hydraulic system is a crossflow system with good energy saving effect and stable quality. The hydraulic system is equipped with German imported equipment and constant power control. It has pressure cutting and load-sensitive technical functions.The hydraulic valve selects the German import hydraulic control pilot proportion multi-way valve, the quality is reliable, the operation simple saves the effort. 12.Automatic lubrication device is selected for effective lubrication of rotating parts such as pin shaft to guarantee the service life of the equipment.
