.Rock Drilling Rig
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, and can also be used for drilling in other mines or geotechnical engineering. It can also be used for water exploration in coal seams. Its English name is
. The rock electric drill has strong overload capacity, which can reduce part of the drill stuck or drill through, and has a high porosity rate due to gangue inclusions. The drilling rig needs to be equipped with a drilling frame, and can drill holes in any direction, such as horizontally forward or tilted upward.
. Dry drilling is strictly prohibited with water exploration drilling rigs (except when using spiral blade drill pipes). The method of water supply first, then drilling, and first stopping drilling and then stopping water is strictly implemented. Pay attention to the water supply situation during drilling. If the water suddenly stops, you must stop drilling immediately to make the drill bit leave the bottom of the hole in time to prevent the drill bit from being blocked and stuck.

.When drilling a hole with a soil drilling rig, slowly rotate the handwheel 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 machine will quickly retreat. 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.
During the drilling process, if the drill pipe is bent or stuck, the drill should be withdrawn immediately to check whether the drill bit is blunt or chipped, whether it encounters a hard fault or whether the voltage at the motor incoming terminal meets the rated voltage. If the voltage is lower than the rated value, it must be adjusted to the rated value.
When drilling a rock hole, the flow rate of water is the pressure. In order to extend the service life of the drill bit and improve the working conditions of the operator, water-discharged or wet drilling is used. During the drilling operation, the electric drill can advance by itself and quickly retreat by simply operating the handwheel.
It is an electric tool with a rotary cutting mechanism and an automatic feeding mechanism, used for medium-hard and rock drilling blastholes.
Operation method: Determine the erection position of the drill frame (self-made) according to the use occasion and the location of the drilling. Install the chain on the main machine, then install the main machine on the runway, connect both ends of the chain to the runway, and adjust The chain tie rod is used to obtain a certain tension on the chain and fix the track to the drill frame.
