To address the low harvesting and baling efficiency and high labor demand of industrial hemp,this paper de-signs a self-propelled combined harvester-baler integrating picking,baling,belt conveying and tracked traveling func-tions.The whole machine adopts a hydrostatic transmission system composed of an engine,hydraulic pumps,hydraulic motors and hydraulic cylinders to realize efficient power split and independent control of each functional unit.This paper elaborates on the structural composition and working mechanism of the picking system,hemp collecting and baling sys-tem,hemp conveying and bale discharging device,as well as the traveling chassis.The design concepts of key compo-nents are analyzed emphatically,including the crank mechanism of hemp collecting tines,baling mechanism,bale-e-ject spring tines,and lateral belt conveying structure.Field application tests demonstrate that the machine meets the standard requirements for indicators such as picking rate and bale forming rate.With reasonable structure and stable op-eration,it can satisfy the mechanized harvesting demands of industrial hemp.
