A drilling device for geotechnical engineering survey, comprising: a connecting frame 1, and also comprising fixed shells 2 arranged on both sides of the connecting frame 1, the top of the connecting frame 1 is fixedly connected with a hydraulic rod 3, the bottom of the hydraulic rod 3 penetrates through the bottom of the connecting frame 1 and is fixedly connected with a movable plate 4, the positions of the movable plate 4 and the limit frame 5 are adjusted by the hydraulic rod 3, and the bottom of the movable plate 4 is fixedly connected with the limit frame 5;

[0023] A first motor 6 is fixed inside the limiting frame 5, and an auger 7 is installed at the bottom of the output end of the first motor 6. The auger 7 can be rotated by turning on the first motor 6, and then the auger 7 can be drilled into the ground for drilling by coordinating with the descent of the hydraulic rod 3. The tops of the two fixed shells 2 are fixedly connected with an auxiliary component 8 for use with the moving and connecting frame 1. The auxiliary component 8 includes a second motor 801 and a gear 802. A push handle 9 is fixedly connected between the rear sides of the two fixed shells 2.

[0024] The top and bottom of the connecting frame 1 are fixedly connected with reinforcing ribs 10. By fixing the reinforcing ribs 10 between the fixed shell 2 and the connecting frame 1, the connection strength between the two can be improved. The side of the reinforcing rib 10 close to the fixed shell 2 is fixedly connected to the fixed shell 2. Both sides of the top of the movable plate 4 are fixedly connected with limiting rods 11. The cooperation between the limiting rods 11 and the positioning rings 12 can improve the stability of the movable plate 4 during lifting and moving. The top of the limiting rod 11 passes through the top of the connecting frame 1 and is fixedly connected with the positioning ring 12.

[0025] The second motor 801 is fixed to the top of the fixed shell 2, and the gear 802 is installed on the front and rear sides of the inner cavity of the fixed shell 2 through bearings. The output end of the second motor 801 passes through the inner cavity of the fixed shell 2 and is installed with a threaded rod 803. The top of the surface of the threaded rod 803 is sleeved with a guide plate 804. The front and rear sides of the guide plate 804 are fixedly connected with a first meshing plate 805. The opposite sides of the two first meshing plates 805 are meshed with the gear 802. The side of the gear 802 away from the first meshing plate 805 is meshed with a second meshing plate 806. The bottom of the second meshing plate 806 is installed with a universal wheel 807. When the device needs to be moved, the threaded rod 803 is rotated by driving the second motor 801. At this time, the guide plate 804 will assist in moving on the surface of the sliding rod 808, and at the same time drive the first meshing plate 805 to rise and mesh the gear 802 to rotate. At this time, the second meshing plate 80 6 will drive the slider 809 to move in the slide groove 810 and make the universal wheel 807 drop down and contact the ground, so as to facilitate the movement of the device body.

The interior of the extension plate 811 is slidably connected to the surface of the slide bar 808, and the two sides of the bottom of the extension plate 811 are fixedly connected with the cone rod 812.

[0026] The working principle of a drilling device for geotechnical engineering investigation provided by the utility model is as follows: first, the second motor 801 can be driven to rotate the threaded rod 803. At this time, the guide plate 804 will assist in moving on the surface of the slide bar 808, and at the same time drive the first meshing plate 805 to rise and rotate the meshing gear 802. At this time, the second meshing plate 806 will drive the slider 809 to move within the slide groove 810 and make the universal wheel 807 descend and contact the ground, so as to facilitate the movement of the device body. After moving to the required position, when the universal wheel 807 is reversed and retracted by the second motor 801, the extension plate 811 will be affected by the rotation of the threaded rod 803 and limit on the surface of the slide bar 808 to drive the cone rod 812 to descend and cone into the ground, thereby positioning the fixed shell 2, and then open the hydraulic rod 3 to make the movable plate 4 drive the limit frame 5 to descend, and at this time, turn on the first motor 6 to cooperate with the auger 7 to rotate, so as to carry out drilling work.
