The first hydraulic cylinder 71 drives the pressure ring 75 to press down to fix the cabbage 6, and then the pressure rod 73 fixed at the lower end of the reader on the grating ruler 76 is pressed down and abuts against the cabbage 6. The diameter of the cabbage 6 can be determined by the vertical displacement of the reader. The current signal emitted by the grating ruler 76 can control the rotation of the second motor 93 and start the first motor 92 at the same time, so that the cutter head 96 in the coring component 9 rotates and rises and falls vertically at the same time. The vertical movement distance of the coring component 9 is controlled by the grating ruler 76, and the coring depth can be adjusted according to the size of the cabbage 6 to ensure complete coring while saving raw materials as much as possible and prevent waste of materials. After the core removal is completed, the rotary conveyor belt 2 continues to rotate, and the cabbage 6 is transported to the bottom of the cutting assembly 8. The second hydraulic cylinder 81 drives the cutter 82 to press down, and the cabbage 6 is cut into multiple portions. Finally, the rotary conveyor belt 2 transports the processed cabbage 6 out of the discharge port 4. The entire core removal process is automated, and the staff only needs to put the cabbage 6 on the rotary conveyor belt 2, which greatly improves production efficiency and saves manpower.
