    Panda Pneumatic small rock blasting drill rig is a convenient compact electric down-the-hole(DTH) drill, it is used to drill blasting holes like small to medium mining projects, national defense projects, irrigation projects, road construction and etc. Our down-the-hole drill is ideal equipment for down-hole blasting.

    Pneumatic drill rig is suitable for harsh work environment and place that traffic is not convenient. It is a wisdom choice for drilling in hard rock of small and medium-sized mine, earth and rock engineering and so on.

    Features:

    1).Applicable type of down-hole impact with high rock drilling efficiency.

    2).With compressed air as the power source, the power is single, safe and reliable.

    3).Simple structure, easy to use, short auxiliary time and light weight


    Operating procedures

    (1) Transportation preparation work
    1). After the drilling rig is transported to the construction site, inspect the components and whether the parts are defective or not, and then assemble and refuel.
    2). First, the two front legs of the carriage are located at the working position, and the support rod is adjusted to determine the angle of the carriage.
    3). Before connecting the motor and the hose, the hose should be carefully cleaned. The pipeline valve can be opened for a few seconds, and the foreign matter in the
    hose is blown off with compressed air.
    4). Check whether the bolts are tightly connected, whether the pipelines are firmly connected, and there is no leakage or oil leakage.
    5). Install an appropriate amount of 30# oil in the oil mister.
    6). The handles of the pneumatic control valve are all placed in the "stop" position.

    After the preparation is completed, the no-load test can be carried out.


    Work procedures

    1). opening
    Raise the reducer to the upper limit position, tighten the drill rod, and then turn on the air motor. After the normal load is normal, slowly open the engine to advance the
    cylinder, place the drill head on the working surface, close the propulsion cylinder, and then open the impactor and drill. Progress. When the drill head is drilled to about
    100 mm, the drill will always maintain a certain propulsive force. Pay attention to observe whether the oil mister supplies oil and adjust the oil supply.
    2). Install rod
    After drilling the first drill pipe, stop the movement of the air motor, close the impactor to stop feeding, set the reducer to the lower limit position, fix the drill pipe
    in the clamp with a fork, reverse the reducer, and make the drill The rod is disengaged from the joint on the reducer. Then raise the reducer to the upper limit position and insert it into the second drill pipe. After the connection is secure, the drilling operation can be performed.
    3). Unloading rod
    When the drill pipe is drilled into contact with the loader, the rotation is stopped, and a special round bar is inserted into the hole on the outer side of the unloader, and the unloader is rotated to make the second flat groove at the end of the drill pipe be aligned. The rectangular groove of the device, inserting the fork, reversing the motor, disengaging the joint on the reducer from the drill pipe, and adjusting the first flat groove on the tail end of the drill pipe to the rectangular groove of the forward
    unloader, inserting Another fork, then remove the fork in the card holder and let the unloader and the other fork drive the drill rod back. (The motor can be moved slowly
    and can not be reversed.) When the second flat groove at the end of the next drill pipe is aligned with the rectangular groove of the fastener, insert the fork and reverse the motor to make the upper and lower drill pipes After the coupling thread is disengaged, take the upper drill rod, slowly lower the reducer, and align the rectangular groove of the unloader to the first flat groove at the end of the next drill pipe, and then repeat the above actions, in turn Remove the drill pipe.
