The series of mining rock electric drills (hereinafter referred to as rock electric drills) have the characteristics of reasonable structure, convenient movement, easy operation, safety and reliability. It is suitable for drilling and water exploration in mines with coal dust hazards. It can also be used for drilling in other mines or geotechnical engineering. It can also be used to explore water in coal seams. Its English name is r.
.The strong overload capacity of the rock electric drill can reduce the stuck part of the drill or drill through the gangue to form a high hole rate. The drilling rig needs a drill frame to drill in any direction, such as horizontally forward or tilted upward.
. Water drilling rigs are strictly prohibited from dry drilling (except when using spiral blade drill pipes) and strictly implement the method of first supplying water, then starting drilling, first stopping drilling and then stopping water. During drilling, attention should be paid to the water supply situation. If water suddenly stops, drilling must be stopped immediately to allow the drill bit to leave the bottom of the hole in time to prevent drill bit clogging and drill sticking.

. When drilling a hole, slowly rotate the hand wheel in the direction of the arrow and gently connect the clutch. When the drill bit body is completely drilled into the rock, tighten the clutch one week later, but not too hard. . When drilling to the required depth, quickly turn the handwheel in the reverse direction to stop advancing. Then press the arrow in the opposite direction to tighten the clutch and the main unit quickly retreats. Wait until the drill bit completely exits the hole before stopping drilling. Otherwise, the drill bit and parts will be easily damaged. At this time, turn the handwheel to the neutral position.
If the drill pipe is bent or stuck during the drilling process, the drill should be withdrawn immediately to check whether the drill bit is blunt or chipped, whether it has encountered a hard break, or whether the voltage at the motor incoming line meets the rated voltage. If it is low, The voltage must be adjusted to the rated value.
When drilling a rock hole, the flow rate of water is &;/the pressure is.&;. In order to extend the service life of the drill bit and improve the working conditions of the operator, water-powder-discharging wet drilling is adopted. During the drilling operation, only the handwheel electric drill can be operated to advance and withdraw quickly.
A power tool with a rotary cutting mechanism and an automatic feeding mechanism for medium-hard and rock drilling blastholes.
Operation method: Determine the erection position of the drill frame (homemade) according to the use occasion and the location of the drilling. Install the chain on the main machine and then install the main machine on the runway. Connect both ends of the chain to the runway and adjust the chain pull rod. The chain acquires a certain amount of tension to secure the runway to the drill frame.
