Embodiment Construction
[0036] see figure 1 , in an embodiment of the present invention, a multifunctional geological survey high-efficiency drilling device includes a detection assembly 5, a derrick 2, and a sliding mechanism 4, wherein the derrick 2 is rotatably mounted on the base 1 through an adjustment mechanism 9, so that The base 1 can be in the form of a vehicle, and the derrick 2 can be rotated on the base 14 to any angle from horizontal to vertical by the adjustment mechanism 9, so as to facilitate the drilling and turnover of the present invention;
[0037] The sliding mechanism 4 is driven by a motor to move along the derrick 2 in a rack-and-pinion manner, which is a prior art, and will not be repeated here. The sliding mechanism 4 is fixedly connected to the upper end of the drilling rod 3, and the The bottom of the drilling rod 3 is fixed with a detection assembly 5, and there are strong and weak electric wires inside, and the length of the drilling rod 3 is approximately equal to the l...
