[0023] The feeding assembly includes two vertically arranged first electric push rods 7. The electric push rod is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. The bottom of the first electric push rod 7 is fixed to the top of the top plate 5. The output shaft of the first electric push rod 7 vertically penetrates the top plate 5, and a lifting plate 8 is fixed to the bottom end of the output shaft of the first electric push rod 7. Specifically, when the first electric push rod 7 is in operation, it can drive the lifting plate 8 to rise and fall.

[0024] The driving assembly includes a motor box 9, the bottom of which is fixed to the middle of the top of the lifting plate 8, a driving motor 10 is fixed inside the motor box 9, the bottom end of the output shaft of the driving motor 10 vertically penetrates the lifting plate 8, and a reducer 11 is fixed to the middle of the bottom of the lifting plate 8. The reducer is a transmission device for low speed and high torque. The power of the electric motor, internal combustion engine or other high-speed operation is meshed with a large gear on the output shaft through a gear with a small number of teeth on the input shaft of the reducer to achieve the purpose of deceleration. The bottom end of the output shaft of the driving motor 10 is fixedly connected to the input shaft of the reducer 11, and the output shaft of the reducer 11 is fixed with a first mounting plate 12. The top of the drill rod 6 is fixedly connected to the first mounting plate 12 through a first fixing bolt 13, that is, the drill rod 6 can be conveniently disassembled and assembled. Specifically, under the deceleration effect of the reducer 11, when the driving motor 10 is running, the drill rod 6 can be driven to rotate, and then when the first electric push rod 7 is running to drive the lifting plate 8 to rise and fall, the rotating drill rod 6 can be driven to rise and fall synchronously, so that the drill rod 6 can pass through the through hole 2 and make a feeding movement downward, thereby drilling and sampling the rock and soil;

[0027] The use process of the utility model is as follows: the staff first moves the device to the desired position, and then fixes the base 1 by inserting the ground rod 20 into the ground, and then runs the drive motor 10. When the drive motor 10 is running, it can drive the drill rod 6 to rotate, and then the rotating drill rod 6 is controlled by the first electric push rod 7 to move downward for feeding movement, so as to perform drilling and sampling operations on the rock and soil. When the drilling of the drill rod 6 is completed, the first electric push rod 7 drives the rotating rod 6 to move upward. At this time, the staff turns on the second electric push rod 14. When the second electric push rod 14 is running, it can drive the two arc plates 16 to move toward each other, so that a number of bristles 17 can brush the surface of the drill rod 6 in the rising stage. That is, the device has the function of drilling and sampling the rock and soil, and can also timely clean the rock and soil adhered to the surface of the drill rod just unearthed, and is convenient to use.
