The invention can organically combine the cutting, the line-dividing clamping and the ordered conveying of the leaf vegetables and the ordered boxing, thereby effectively solving the ordered collection problem after the line-dividing ordered conveying of the leaf vegetables, avoiding the damage of the leaf vegetables caused by multiple times of arrangement, solving the bottleneck of mechanical harvesting of the leaf vegetables, having simple and reliable structure and method, and providing a practical scheme for realizing the same-machine boxing of the ordered harvesting of the leaf vegetables. The same machine is arranged on a harvester, and harvesting, conveying and collecting are carried out simultaneously.
