When drilling to a certain depth, the adjusting motor 4 is turned off and the sampling motor 8 is turned on to rotate the sampling motor 8 360 degrees, thereby driving the plurality of sampling buckets 10 to rotate out of the drill rod 6 and complete the sampling work. Then the adjusting motor 4 is rotated forward, which is convenient for lifting the drill rod 6 upward, and then for pulling the drill rod 6 out of the borehole. Then the sampling motor 8 is rotated by a certain angle, which is convenient for taking samples of different depths out of the plurality of sampling buckets 10.

By extending the electric push rod 15, the roller 16 is easily separated from the contact with the ground, and the equipment is easily locked in position. The base plate 1 slides with the drill rod 6 through the rubber ring pad 18, so that the soil adhering to the side wall of the drill rod 6 can be cleaned.

The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control.

[0022] In summary, the working principle and working process of the geological survey drilling equipment are as follows: when in use, the geological survey drilling equipment is first moved to the surveyed location through the roller 16, and the electric push rod 15 is extended to facilitate the roller 16 to be out of contact with the ground, so as to facilitate the position locking of the equipment, and the adjusting motor 4 is connected to the forward and reverse circuit according to the instructions, and the adjusting motor 4 is turned on to reverse the adjusting motor 4, and the conveyor belt 12 is used to drive the multiple screws 3 to reverse, and the multiple screws 3 are meshed with the adjusting plate 5 to drive the adjusting plate 5 to move downward, thereby driving the drill rod 6 to move downward, and drilling is performed downward through the drill bit 7, and the drilling is performed downward. Through the rotation coordination of the drill rod 6 and the adjusting plate 5, the drill rod 6 is driven to rotate downward to drill a hole. When drilling to a certain depth, the adjusting motor 4 is turned off and the sampling motor 8 is turned on to rotate the sampling motor 8 360 degrees, thereby driving multiple sampling buckets 10 to rotate out of the drill rod 6 and complete the sampling work. Then, the adjusting motor 4 is rotated forward, which makes it easy to lift the drill rod 6 upward, and then it is easy to pull the drill rod 6 out of the borehole. Then, the sampling motor 8 is rotated by a certain angle to facilitate taking samples of different depths out of multiple sampling buckets 10. Then, the electric push rod 15 is shortened to make the roller 16 contact the ground, and the equipment is moved to the next survey location to continue to repeat the above operations.
