The flexible inner clamping mechanism is located between the two rows of cabbage. The two flexible outer clamping mechanisms are respectively located on the outer sides of the two rows of cabbage. The two cutting discs 2403 are respectively located below the two flexible outer clamping mechanisms. After the roots of the cabbage are cut off by the multiple blades 2404 on the cutting discs 2403, the cut cabbage is conveyed toward the conveyor through the flexible inner clamping belt 2309 and the flexible outer clamping belt 2306. The frame 20 is used for conveying, and during this process, the lifting plate 26 plays a role in raising the height of the cabbage to ensure that the cabbage can fall smoothly onto the chain conveyor 17. At this time, the chain conveyor 17 plays a conveying role and conveys the cabbage to the lower end of the lifting device 11. At this time, the lifting device 11 plays a conveying role.

The platform 18 moves with the main frame 9, which is convenient for the staff to follow the operation.

[0047] In a further embodiment of the utility model, the loading and conveying device 13 can be designed as a conveyor belt mechanism, or only a supporting cross plate with a relatively smooth upper surface can be used, and the staff can stand on the transport vehicle to grab the cabbage and place it.

[0052] In a further embodiment of the utility model, the lifting cylinder 10, the loading cylinder 12, and the depth control cylinder 27 are all connected to the double pump 6 through hydraulic pipelines and controlled on and off by electromagnetic control valves.
