　　Produced by our factoryKHYDtwo hundred and ninetyRock electric drill for coal minesMainly used for mining tunnel excavation, road construction, water conservancy construction, metallurgical mining, and rock engineering operations, the quality of work determines the quality of products,11kwRock electric drill for coal minesOur company's consistent principle is that product quality determines the rise and fall of an enterprise. Below, I will introduce it to youRock electricity for coal minesdrill.

　　1KHYDtwo hundred and ninetyRock electric drill for coal minesSuitable for drilling and water exploration in mines with methane or coal dust hazards, and can also be used for drilling in other mines or geotechnical engineering. The KHYD series drilling rig has strong overload capacity, which can reduce some stuck or penetrated drilling, and has a high rate of hole formation due to rock inclusion. The KHYD series drilling rig requires a drilling frame to cooperate and can drill holes in any direction such as horizontal forward or inclined upward. In order to extend the service life of the drill bit and improve the working conditions of the operator, wet drilling with water powder discharge is adopted. During the drilling operation, only the handwheel needs to be operated, and the electric drill can advance and quickly retract on its own

　　IIKHYDtwo hundred and ninetyRock electric drill for coal minesWorking Principle:

　　The electric motor of the drilling rig reduces the spindle speed to 230 r/min through two-stage gear reduction; By using a worm gear system, friction clutch, and sprocket chain system, rotational motion is transformed into linear motion; The main engine is slowly advanced on the frame through a single head left-hand worm gear system and a double-sided friction clutch, while the main engine is on the frame through a double head right-hand worm gear system and a double-sided friction clutch Quickly return. When the double-sided friction clutch is engaged, the main engine moves forward or backward; When the double-sided friction clutch is not engaged, the main engine only rotates and does not move forward or backward.

　　When the drilling rig is not in use, it should be placed in a dry place to prevent rusting and damage.

　　Before the drilling rig starts working, butter should be applied once a week to the moving joint surface and surfaces that are prone to rust.

　　3. During shift handover, it is necessary to carefully inspect the integrity and performance of the drilling rig, promptly record and handle any problems found, and the drilling rig must not operate with defects.

　　During the operation of the drilling rig, attention should be paid to the operation of the motor and deceleration parts at all times. If any abnormal noise is found in the motor and deceleration parts, or if the shell temperature exceeds 60 ℃, the machine should be stopped immediately for inspection and analysis of the cause.

　　5. Based on the operating conditions and noise of the drilling rig, timely determine the wear condition of the drill bit in the hole, and replace the drill bit in a timely manner when the wear damage is severe.

　　During use, the drilling rig must not be dropped, smashed, or subjected to gravitational impact.

　　7. Generally, the drilling rig is required to undergo major repairs every six months and minor repairs every three months.
