Further, the biside plate fore-end hollow out of described body forms the native grizzly of leakage.When operation, the potato piece and the soil that are excavated enter elevating chain compass screen surface, and many soil drains into rapidly machine outside from leaking native mesh screen, has reduced the load of elevating chain compass screen surface, has increased and has gone native effect, has improved exposed potato rate, has reduced elevating chain operation power consumption.
Further, described bar strip elevating chain comprises one group of bar strip and the carrier bar that is arranged on bar strip two ends, and described bar strip is by circular gasket and carrier bar pin joint, and whole elevator compass screen surface without knife-edge, has ensured in potato piece course of conveying and has not been scratched, effectively reduced damage ratio.
Further, be fixed with the broken ridge cutter of " < " shape cutting edge on front end two heel posts of described body, when reaping machine previous operation, soil and the weeds of Dao Jianglong side, broken ridge break, and reduce to gather in the crops the resistance that moves ahead, and reduce power consumption.
Further, described body front bottom end is also provided with taper digger blade, and convenient excavation broken ground.
Further, described adjusting screw(rod) rear end is provided with adjusting bolt handle.Can draw complete machine around the rotation of reaping machine power shaft, in the situation that hanger bracket is fixing with tractor, realize the adjustment at reaping machine excavation inclination angle, make it to adapt to the different dark job requirements of digging.
The utility model course of work is: by adjusting screw(rod) handle, whole body can be rotated up and down around hanger bracket, thereby realize the adjustment of complete machine excavation penetrating angle and elevator angle; Body is provided with the input sprocket being connected with side of tractor power take-off, and the output shaft of input sprocket is connected with the second output shaft by dog clutch, and the second output shaft is connected with the bar strip elevating chain of body by driving-belt, realizes the input of tractor dynamic power; The sweet potato having been dug by digger blade and soil block are upwards carried, in course of conveying, part soil is assorted leaks down from the gap of bar strip elevating chain and the leakage of frame front end biside plate soil grid gap, final sweet potato and part soil block drop underground from elevating chain rear end, the tiling of potato piece on the ground; Described frame rear end both sides connect ship type depth stop kickboard by spring flexible, in the time excavating load increase, automatically regulate and excavate penetrating angle and elevator compass screen surface angle, and restriction is dug deeply, accelerate potato soil velocity through screen, reduce excavating resistance.
The beneficial effects of the utility model are: the utility model can effectively alleviate the defeated load up of compass screen surface, increase potato soil separating effect, improves exposed potato rate; Broken ridge moves ahead, reduces resistance; In operation process, automatically adjust and dig deeply, guarantee is dug deeply basically identical, improves operation smoothness, reduces overload power consumption, in addition excavating depth adjusting facility.Abovementioned technology has effectively met hilly upland machine coordination power is little, physical features planarization is poor production feature and job requirements.
