Abstract
The utility model provides a small-sized vibrating screen type potato digger, which belongs to the field of agricultural machineries and is suitable for work in small fields like terraces, hills, mountains and others. The small-sized vibrating screen type potato digger comprises a rack (1), an inclined pull bar (3), a digging shovel assembly (7), a swing mechanism (1), a transmission mechanism (8), a spacing mechanism (5), a clutch (6), and a hanging mechanism (4). The rack (2) is hung to a traction box of a tractor through the suspension mechanism (4). The suspension mechanism (4) is provided with a rectangular chute, and a beam frame of the spacing mechanism (6) traverses through the chute. The digging depth can be changed as the position of the beam frame of the spacing mechanism (6) in the chute changes. The digging shovel assembly (7) is fixedly connected to the swing mechanism (1) through a bolt. The transmission mechanism (8) is disposed between the hanging mechanism (4) and the swing mechanism (1). The inclined pull bar is disposed between the swing mechanism (1) and the suspension mechanism (4). The small-sized vibrating screen type potato digger is advantageous in that the function of the digger matches with a small-power hand tractor, meeting the demand of digging work in small fields like terraces, hills, mountains and others; the problems of a conventional small-sized potato digger that digging resistance is large, and digging angle of the digging shovel cannot be adjusted can be resolved.
