[0024] In the above specific technical scheme, the power head mechanism includes a moving cylinder 9 and a power head body 8. Starting the moving cylinder 9 can drive the power head body 8 to move in the horizontal direction, so that the center of the power head main shaft can deviate from the drilling center, which greatly reduces the labor intensity and effectively improves the drilling work efficiency. The boom 3 is driven by the boom lifting cylinder 6 installed on the boom support seat 2 to perform lifting and lowering movements, and the power head mechanism is driven by the power lifting cylinder 4 installed on the boom 3 to perform lifting and lowering movements. The combined guide rail is accurately centered, and the power lifting cylinder 4 and the boom lifting cylinder 6 are distributed up and down. The power head mechanism is symmetrically stressed when lifting and lowering, and the sliding is smooth. The device has a compact structure, reliable operation, and convenient and quick operation.

[0025] A boom diagonal support cylinder 10 is installed on the frame 1, and the output end of the boom diagonal support cylinder 10 is connected to the boom support seat 2. The boom 3 is installed on the boom support seat 2 through a connecting pin 24. The inclination angle of the boom 3 can be adjusted by the boom diagonal support cylinder 10.
