The electric-controlled clamping and rotating mechanism 3 is fixed on the bracket to drive the drill rod 41 to rotate, thereby achieving the function of automatic rod removal. The multi-section threaded cutting drill rod mechanism 4 is connected by a threaded joint to deliver the rod. A soil crushing device is installed inside the drill rod 41 to cut and suck large soil blocks appearing in the loess to prevent the drill rod 41 from being blocked.

The fixed plate 11 is welded to the front end of the base plate, and the fixed plate 11 is bound to the ball screw lifting platform 12 by bolt connection. At the same time, the electric push rod support frame 14 is bolted to the workbench of the ball screw lifting platform 12, and the electric push rod 13 is bolted to the bracket. The pin connects the front end of the electric push rod 13 and the two rigid connection keys 15. Similarly, the pin connects one end of the rigid connection key 15 to the two handle ends of the mechanical scissors 16. The mechanical scissors 16 are composed of two steel plates. By using the up and down movement of the ball screw lifting platform 12, the fixture can be controlled to clamp the drill rod 41 at different positions, and the drill rod 41 can be driven to connect with the reducer 5 to reduce the working time. The electric push rod 13 shrinks the mechanical scissors 16 through telescopic action to form a fixture.

Image preprocessing is performed through Opencv software, including graying, noise removal, and edge detection, so that the outline of the foreign body is clearer. The background is removed by using regional segmentation technology to separate the foreign body from the complex background. The outline of the foreign body is obtained by the Canny edge detection algorithm, and the shape and area of ​​the foreign body are obtained by the contour detection algorithm. The major axis and minor axis of the soil block are calculated to determine whether its size meets the screening criteria. An alarm system with an alarm threshold set according to the size of the foreign body. When a foreign body exceeding the threshold is detected, the signal is sent to the PLC control system for signal processing, and then a light alarm is issued.
