Drilling procedure and rod unloading method of the drill:
1, when opening the hole, the first with small impact work, propulsion force and low speed drilling, in order to facilitate the needle positioning,(need to dust, give the appropriate water to reduce dust) when the needle drilling 10 cm or so, and then with the full throttle impact, and appropriately increase the propulsion force, improve the speed,(need to dust the gas water mixture to maintain the appropriate proportion), normal rock drilling work, drill a drill The rod should stop the operation of the wind motor and stop the air and water supply to the impactor. The fork should be inserted into the drill pipe groove of the bracket to make the wind motor reverse and the slide back, so that the joint and the drill pipe can be detached, and then the second drill pipe can be connected for drilling, and so on.
2. Discharge rod method: The discharge rod of drill pipe is semi-automatic, which is realized by the coordination of discharge rod, support and two forks and the reversal of the wind motor. When the rod is discharged, the return transfer moves back when the second slot of drill pipe (drill pipe male joint end by the middle of the drill pipe) and the four square frame of the bracket is opposite, insert the second slot with a fork, and then reverse the motor, when the four square frame of the rod disconnector and the first slot of the drill pipe (drill pipe male joint end by the trough of the drill pipe end) is opposite, insert the second fork firmly, take out the first fork (the fork in the bracket four square frame), The propulsion cylinder is operated, so that the rod disloader drives the drill pipe to move backward. When the second groove of the second drill pipe is in support of the drill pipe groove, the motor is reversed. When the screw buckle of the two drill pipes is removed, the first drill pipe is removed in turn.
