After that, the knotting motor 401 drives the knotter 402 to rotate counterclockwise for several times, and the margins at the two ends of the iron core tie 411 are withdrawn from the two knotting seams 4024, thus completing the knotting.

The working process of the chive combine harvester is as follows. When the harvester travels in the chive field, the harvested chives are lifted by the seedling supporting guide device 1 and introduced into the clamping entrance of the clamping conveying and laying device 2 to clamp the seedlings; at the same time, the cutting device 14 sticks to the ground to cut off the chive stems, and the cutting height position of the stems can be set by adjusting the height limiting profiling wheel 15. The cut chives are clamped by two flexible clamping conveyor belts 203 and conveyed to the back and up, and the chives are gradually lowered from the upright state to the horizontal during the conveying process, and the chives are thrown horizontally on the horizontal conveyor belt 302 at the rear end of the horizontal conveying device 3. Under the conveying action of the horizontal conveyor belt 302, the vegetables are conveyed above the bundling device, and directly fall into the semicircular buncher 601 under the action of gravity. When the semicircular buncher 601 is fully collected, the horizontal conveying mechanism is suspended, and then the transverse push motor 605 operates; through the engagement between the gear and rack, the rotation of the output shaft of the transverse push motor 605 is converted into the linear motion of the push plate support 604, which slides along the transverse pushing slide rail 608, so that the push plate connecting rod 603 drives the bundling push plate 610 to push the bundled vegetables to the baling mechanism 4; at this time, the output rod of the push-up motor is in a retracted state, and the two strapping claws 403 are in an open state, and the iron core tie 411 is located in the U-shaped openings 4031 at the tops of the two strapping claws 403; at this time, the tie cutter has cut off the iron core tie, so that the iron core tie 411 passes through the U-shaped openings 7501466 4031 and has a certain margin at the outer sides of both openings. After the vegetables are bunched, the transverse push motor 605 rotates reversely, and the push plate connecting rod 603 drives the bundling push plate 610 to reset. The push-up motor 407 pushes the push-up slider 409 to move up along the chute, and pushes the two strapping claws 403 to gather up with the cut iron core tie 411 and the bundled vegetables through the two push-up connecting rods 410; when the U-shaped openings 4031 at the ends of the two strapping claws 403 are opposite, the vegetables have been gathered into bundles, and the margins at both ends of the iron core tie 411 are placed on both sides of the knotting wheel body 4022 under the constraint of the U-shaped openings 4031; then, driven by the knotting motor 401, the knotter 402 rotates both ends of the iron core tie to tie the knot and complete the baling.
