After cutting is completed, it is reset by the return spring 408; the clamping and lifting mechanism 500 is installed on the overall lifting mechanism 300 and is located above the cutting mechanism. The clamping and lifting mechanism 500 includes a clamping device 513 installed on the clamping and lifting mechanism 500. The pressure ring 303 descends under the drive of the motor, the clamping device 513 clamps the cabbage, and the cutting mechanism 400 cuts and removes leaves; the mobile transmission mechanism 600 is installed on the fixed frame 100, including a conveyor belt frame 607 and a transmission belt 613. The conveyor belt 613 moves under the drive of the motor to realize the transmission of the cabbage. The overall structure of the present invention is compact, and the machine is small in size. It can be used in narrow fields and is more suitable for flexible operations in small areas. According to the appearance characteristics and physical properties of cabbage, an integrated leaf removal and harvesting process suitable for cabbage is designed, and root cutting is used for refined harvesting to reduce surface damage of cabbage. The multi-stage lifting and spatial interlacing design divides the cabbage transportation into two parts, vertical and horizontal, with high spatial flexibility, which is conducive to freely changing the size and setting different collection areas, reducing spatial interference in field operations.

[0031] like Fig.11As shown, when working, the machine is started, and the machine automatically moves between the ridges. At the same time, the camera starts working to identify the cabbage within the field of view. When the visual recognition module recognizes that the cabbage is in the center of the device, the machine stops moving and starts cutting and harvesting. The overall lifting mechanism descends, and the pressing ring is aligned with the inner core of the cabbage. At the same time, the outer old leaves of the cabbage are flattened to the surroundings, and the cutting wire ring formed by the return spring and the cutting wire reaches the root of the cabbage. Then the clamping claw closes to clamp the inner core of the cabbage, and the first screw slide runs, so that the cutting wire ring shrinks under the action of tension, and the outer old leaves and the roots of the cabbage are cut off and discarded together. The processed cabbage is lifted by the clamping claw lifting mechanism and conveyed by the moving conveyor belt mechanism, and then falls into the harvesting device, thereby realizing the whole process of automated cabbage harvesting and storage.

The first screw slide 301 is installed on the bottom crossbeam of the fixed frame 100, and the upper side is fixed to the door-shaped frame at one end, serving as the main load-bearing and driving structure of the lifting part. The pressure ring 303 is installed on the first screw slide 301 as the base support of the lifting part, and the internal aperture is larger than the inner core of the cabbage. The support plate 305 has a semi-lunar arc structure, which is tangent to the inner and outer circles of the pressing ring, and plays a role of stable support and edge limit, ensuring that the displacement of the cabbage in the working space is not too large. The support plate 305 is installed above the pressing ring 303 through the support column 304 to form a certain vertical cavity.
