In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0047] In the specific use of this embodiment, when it is necessary to cut the stems of vegetables, the staff first drives the entire device to move by using the two handles 14, the two push-pull rods 13 and the plurality of universal wheels 12. After the entire device is moved to a suitable position, the rotating motor 64 is started by the external PLC. The output shaft of the rotating motor 64 rotates to drive the rotating shaft 63 coaxially connected thereto to rotate. The rotating shaft 63 rotates to drive the turntable 62 coaxially fixed thereto to rotate. The rotation of the turntable 62 drives the lifting plate 5 fixed thereto to rotate. The rotation of the lifting plate 5 drives the clamping mechanism 7 on its top surface to rotate, thereby driving the two clamping rods 75 and the two protective plates 76 to rotate. When the two protective plates 76 rotate to a suitable angle position, the rotating motor 64 is turned off by the external PLC and the electric cylinder 81 is started. The piston rod of the electric cylinder 81 moves to drive the fixed box 61 fixed thereto through the gasket 82 to be lifted and lowered. The lifting and lowering of the fixed box 61 also indirectly drives the two clamping rods 75 and the two protective plates 76 to be lifted and lowered.

[0048] When the two guard plates 76 and the two clamping rods 75 move to a suitable height position, the electric cylinder 81 is closed and the clamping motor 710 is started through the external PLC, and the output shaft of the clamping motor 710 rotates to drive the rotating shaft 711 coaxially connected thereto to rotate, and the rotating shaft 711 rotates to drive the same-side gear 79 coaxially fixed thereto to rotate, and the rotation of the gear 79 drives another gear 79 meshing therewith to rotate, and the rotation of the other gear 79 drives the rotating rod 78 coaxially fixed thereto to rotate, and the rotation of the rotating rod 78 drives the same-side rotating column 72 coaxially fixed thereto to rotate, and the rotation of the rotating column 72 drives the two-way screw rod 73 coaxially fixed thereto to rotate, and the rotation of the two-way screw rod 73 drives the two moving rods 74 threadedly connected thereto to approach each other, and the moving rod 74 moves under the guidance of the guide block 77 on the same side and the guide groove on the top surface of the lifting plate 5, and the two moving rods 74 approach each other, thereby driving the two clamping rods 75 and the two guard plates 76 to approach each other, and when the guard plates 76 are in close contact with the vegetable stems, the clamping motor 710 is closed through the external PLC;

[0049] Then, the harvesting motor 97 is started through the external PLC. The output shaft of the harvesting motor 97 rotates to drive the roller 92 on the same side connected thereto coaxially. The rotation of the roller 92 drives the screw 93 coaxially fixed thereto to rotate. The rotation of the screw 93 drives the connecting rod 94 threadedly connected thereto to move. The connecting rod 94 moves under the guidance of the slider 96 and the guide groove on the left surface of the working plate 1. The movement of the connecting rod 94 drives the cutting knife 95 fixed thereto to move. The cutting knife 95 can cut the stems of the vegetables during the movement. When the cutting is completed, the harvesting motor 97 is turned off through the external PLC. Then, the electric cylinder 81 and the rotating motor 64 are started through the external PLC. According to the above, the harvesting motor 97 can be turned off through the external PLC. The angle and height position of the two protective plates 76 and the two clamping rods 75 are adjusted. When the two protective plates 76 and the two clamping rods 75 move to the top of the conveyor 2, the electric cylinder 81 and the rotating motor 64 are closed by the external PLC, and the conveyor 2 and the packaging machine body 3 are started. At the same time, the output shaft of the clamping motor 710 is started and controlled to reverse by the external PLC. The output shaft of the clamping motor 710 is reversed so that the two protective plates 76 and the two clamping rods 75 can be moved away from each other, so that the harvested vegetables can be transported to the top surface of the conveyor belt 22, and then the vegetables can be transported. During the transportation process, the vegetables can be initially packaged by the packaging machine body 3, and the packaged vegetables can be collected by the collection box 4.
