The double-headed motor 64 will drive the belt 58 to rotate at the same time, thereby driving the transmission gear plate 56 and the driven gear plate 57 to rotate with the mechanical energy, so as to achieve the coordinated operation of the baffles 61 in the symmetrical position.

[0058] The working principle of embodiment 1 is: the running conveying structure 1 and the harvesting processing structure 2 are combined and arranged, and the running conveying structure 1 and the harvesting processing structure 2 are connected to an external traction device to drive the running conveying structure 1 and the harvesting processing structure 2 to operate;

[0059] First, the user pre-adjusts the angle of the auxiliary harvesting screw 52, ​​and the third motor 44 drives the motion ring frame 45 and cooperates with the adjustment main rod 46 to rotate, so that the auxiliary harvesting screw 52 is adjusted in angle, and at the same time, the upper docking shaft 50, the first articulated frame 51, and the second articulated frame 53 rotate accordingly to help the auxiliary harvesting screw 52 to support and connect, and at the same time, the auxiliary harvesting screw 52 is driven to operate through the internal driving structure, and the auxiliary harvesting screw 52 rotates at this time;

[0060] At the same time, the double-headed motor 64 works, driving the half gear rack 63 to rotate, driving the active gear rack 66 to rotate accordingly, so that the limit lifting rod 60 and the baffle 61 are adjusted accordingly, and reciprocating cutting is realized. When idling, the limit lifting rod 60 is reset and connected through the reset adjustment seat 59. When the double-headed motor 64 is driven, the belt 58 is driven to rotate accordingly, thereby driving the driven gear disc 57 to rotate. The driven gear disc 57 drives the transmission gear disc 56 to rotate, so that the symmetrical baffle 61 is adjusted accordingly.

[0061] Afterwards, when the conveying structure 1 and the harvesting processing structure 2 are in operation, the harvesting blade 62 cooperates with the blade under the baffle 61 to perform processing to achieve cabbage cutting. At the same time, when the auxiliary harvesting screw 52 rotates, the cabbage can also be harvested so that the cabbage reaches the conveying seat 54.

[0062] At this time, the cabbage reaches the upper part of the power seat 21 and the second peeling gear 22 through the conveying connecting seat 54, the peeling processing component 6 starts working, and the second motor 35 drives the rotating piece 36 to rotate, thereby driving the rotating rod 37 and the push-type connecting frame 38 to move, so as to realize the follow-up adjustment of the sleeve seat 39 and the front sleeve seat 40. The sleeve seat 39 and the front sleeve seat 40 are connected with the first extrusion wheel 29 and the second extrusion wheel 31, so that the first extrusion wheel 29 and the second extrusion wheel 31 change their positions through the universal shaft 27. At the same time, the motor 28 drives the first extrusion wheel 29 and the second extrusion wheel 31 to rotate. When the front sleeve 40 is adjusted, the first connecting frame 32 can be pulled by the hinge rod 33 and the second connecting frame 34 to adjust. The first connecting frame 32 allows the first extrusion wheel 29 and the second extrusion wheel 31 at the upper position to be adjusted accordingly, thereby changing the spacing distance between the ends of the three front sleeves 40. When the first extrusion wheel 29 and the second extrusion wheel 31 rotate, the dead skin and bad skin are removed and preliminary treatment is performed.

[0063] Afterwards, the cabbage reaches the threaded feeding rod 15, and the threaded feeding rod 15 is driven so that the cabbage cooperates with the threaded feeding rod 15 for transportation. At the same time, the first motor 17 drives the first peeling gear 19 to work, and the second peeling process of the cabbage is realized through the contact of the first peeling gear 19;

[0064] Finally, the cabbage arrives at the conveyor belt 10, changes its position through the conveyor belt 10, and then is transmitted to the centrifugal disk 9. The rotation of the centrifugal disk 9 causes the cabbage to move centrifugally, performs the reversing transmission work, and completes the work.
