Leaf vegetable orderly harvesting and collecting device

The invention discloses a leaf vegetable orderly harvesting and collecting device which comprises a power crawler walking chassis, a header obliquely arranged on the power crawler walking chassis, a second-stage conveying mechanism and a third-stage conveying mechanism which are sequentially arranged on the rear portion of the power crawler walking chassis from top to bottom, and a cutting component is connected with the second-stage conveying mechanism through an elastic tooth conveying groove. A front profiling mechanism is arranged at the front end of the header, the height of the header is adjusted in real time through the front profiling mechanism, harvested leaf vegetables are conveyed to an elastic claw conveying groove through two sets of special-shaped clamping conveying belts on the header, and the leaf vegetables sequentially enter a secondary conveying mechanism one by one in the elastic claw conveying groove. Leaf vegetables are flatly laid through the second-stage conveying mechanism and enter a
