The invention provides a self-propelled potato
combine harvester with a residual film
recovery device, belongs to the technical field of
agricultural machinery, and solves the problems of high soil carrying amount, residual film winding, large potato block damage and the like in film-covered potato harvesting. The
machine comprises a main
machine frame, a crawler belt walking mechanism, a power
system and a harvesting mechanism, a secondary soil shaking conveying mechanism, a secondary soil shaking screening mechanism, a lifting conveying mechanism, a cleaning conveying mechanism and a bag hanging mechanism which are arranged in the advancing direction, and a
continuous operation chain is formed. The core is that the harvesting mechanism is integrated with a residual film
recovery device, and the front
recovery of the residual film is realized through film guiding, film pressing, reciprocating film pulling and winding. The whole
machine is of a multi-stage soil shaking and screening and low-damage conveying structure, a power
system achieves power distribution and speed regulation through a hydraulic
electromagnetic valve set, and all the mechanisms are assembled in a modularized mode to adapt to different soil textures and
ridge types. The potato harvester integrates harvesting and residual film recycling, is high in potato cleaning rate, low in potato block damage, high in
continuous operation capacity and convenient to maintain, and meets the large-scale and green potato production requirements.
