Then start the push rod 10 by operating the control panel 17, so that the telescopic end of the push rod 10 extends to push the cutter 7. During the pushing process, the staff needs to use both hands to press the device tightly through the handle 3, and then push the push rod 10 to make the cutter 7 cut the soil around the corn stalk, so that the corn root system can be separated from the entire land.

[0025] Specifically, such as Figure 3 As shown, the sleeve hole 5 is located between the support columns 4, the movable groove 6 is located on the outside of the support columns 4, and the pushing end of the pushing rod 10 is fixedly connected to the top of the limiting plate 8.

[0027] The installation of the anti-slip strip 12 can increase the friction between the clamping plate 11 and the corn stalks, thereby making the clamping of the corn stalks more stable.

[0028] Specifically, such as Figure 4 and Figure 5 As shown, the output end of the rotating motor 13 passes through the interior of the top of the partition plate 9, and a clamping structure is installed at the bottom of the partition plate 9. The clamping structure includes a collar 51 fixedly connected to the middle of the bottom of the partition plate 9. The inner side surface of the collar 51 is provided with a limiting slide groove 52 in an annular array. A lifting rod 53 is sleeved inside the collar 51. The bottom of the lifting rod 53 is fixedly connected to a clamping ring 54.

[0035] Then start the rotating motor 13, so that the rotating motor 13 drives the transmission shaft of its transmission end to rotate. During the rotation process, since the output end of the rotating motor 13 is threadedly connected to the threaded hole 56 at the top of the lifting rod 53, and the limiting slider 55 is adapted to the limiting slide groove 52, the lifting rod 53 and the clamping ring 54 at its bottom can be driven to descend.
