The invention relates to the technical field of
agricultural machinery, in particular to a small boxing type potato harvesting combined
machine. The small boxing type potato harvesting combined
machine comprises a rack, a traction hanging frame, a composite digging
shovel, a transmission device, a vibration separation device, an eccentric wheel mechanism and a supporting wheel, wherein the composite digging
shovel, the supporting wheel and the vibrating screen are connected to the lower end of the rack correspondingly, and the eccentric wheel mechanism is installed at the upper end of the rack. The eccentric wheel mechanism is used for simultaneously driving the digging
shovel and the vibrating screen, so that the digging shovel and the vibrating screen simultaneously reciprocate in the horizontal direction, and the design concept of coaxial transmission but different amplitudes is adopted, so that the horizontal amplitude of the vibrating screen is increased while the digging resistance is reduced as far as possible, potatoes and soil are separated more thoroughly in addition, a rotary
barrel frame collecting device is designed, and the integrated operation process of digging, soil screening and boxing is achieved, and another function is to further realize potato-soil separation, so that the collected potatoes are cleaner, meanwhile, vibration optimization is conducted on the digging shovel, the resistance of the
machine is reduced, and meanwhile the digging shovel and the vibrating screen are connected more compactly.
