[0019] The embodiment of the present application discloses a drilling device for geotechnical exploration.

[0020] Reference Figure 1 A drilling device for geotechnical exploration includes a base 1, which is arranged in a rectangular frame shape, and the lower surface of the base 1 is arranged in a wavy shape. The base 1 is rotatably connected to a bracket 2 in the middle, and support assemblies 3 are respectively arranged at both ends of the base 1. The two support assemblies 3 are located on both sides of the bracket 2, and the support assemblies 3 are connected to the bracket 2. The bracket 2 is slidably connected to a horizontal lifting platform 4, and the lifting platform 4 is fixedly installed with a drilling motor 41 by bolts. The output shaft of the drilling motor 41 is fixed with a first flange 42, and the first flange 42 is fixedly connected with a second flange 43 by bolts, and the second flange 43 is fixedly connected with a drill rod 44, so that the drill rod 44 can be replaced according to different drilling needs.

[0021] Reference Figure 1 The bracket 2 is provided with a lifting assembly 5 for lifting the lifting platform 4. The lifting assembly 5 includes an upper cross bar 51 and a lower cross bar 52 respectively welded to the upper and lower ends of the bracket 2. A vertical screw rod 53 is rotatably connected between the upper cross bar 51 and the lower cross bar 52 through a bearing. The lifting platform 4 is threadedly connected to the screw rod 53. A lifting motor 54 is fixedly installed on the upper cross bar 51. The output shaft of the lifting motor 54 is coaxially fixed to the upper end of the screw rod 53 downward, thereby driving the lifting platform 4 to drive the drilling motor 41 to move up and down.

[0022] Reference Figure 1 The support assembly 3 includes a support rod 31 rotatably connected to the base 1, the support rod 31 is hollow and has an open end, a telescopic rod 32 is threadedly penetrated at the open end of the support rod 31, one end of the telescopic rod 32 is threadedly connected to the support rod 31, and a pin rod 33 is slidably penetrated at the other end of the telescopic rod 32, and the bracket 2 is provided with a plurality of pin holes 34 for positioning the pin rod 33, and the plurality of pin holes 34 are arranged equidistantly along the length direction of the bracket 2.
