[0029] The gearbox body 4 and the drilling mechanism 5 are driven to rotate by the rotating mechanism 2 , so that the horizontal angle of the drilling mechanism 5 can be changed to meet the horizontal drilling angle requirement, and the height of the drilling mechanism 5 can be changed by the lifting mechanism 3 .

[0030] like Figure 2 , Figure 3 As shown, the output end of the rotary reducer 21 is fixedly connected to a rotating shaft 22, the outer wall of the rotating shaft 22 is fixedly connected to the rear of the support seat 23, the right part of the rotating shaft 22 is rotatably connected to the top of the mounting plate 1, the right end of the support seat 23 is fixedly connected to a guide block 24, the outer wall of the guide block 24 is slidably connected to the inner wall of the guide groove 12, and the guide block 24 has a T-shaped shape.

[0031] By starting the rotary reducer 21, the rotating shaft 22 is driven to rotate, and the rotating shaft 22 drives the support seat 23 to rotate synchronously. When the support seat 23 rotates, the guide block 24 is driven to slide on the inner wall of the guide groove 12. The guide block 24 guides the support seat 23, so that the support seat 23 rotates more smoothly without deviation.

[0032] like Figure 2 , Figure 3 As shown, the left end of the mounting plate 1 is fixedly connected to a support rod 25, and the left end of the support rod 25 is fixedly connected to a limiting sleeve 26, the shape of the limiting sleeve 26 is arc-shaped, and the inner cavity of the limiting sleeve 26 is movably connected to a limiting rod 27, the shape of the limiting rod 27 is arc-shaped, and the top end of the limiting rod 27 is fixedly connected to the bottom end of the support seat 23.

Subsequently, when working, the lifting cylinder 32 is restricted by the two-way hydraulic lock 34 to prevent hydraulic leakage, thereby ensuring the height stability of the drilling mechanism 5 and increasing the stability. Afterwards, according to the required drilling angle The device is adjusted and the rotary reducer 21 is started to drive the rotating shaft 22 to rotate.
