Its course of work is：
Soil is cut in driving for potato picker and firming adjusting apparatus passes through upper spider 1 and self propelled harvester support body
Connection, and run forward under the induced effect of self propelled harvester support body, hydraulic motor 10 drives two groups to cut native adjustment respectively
Two cutting soil disks 92 that device is connected on same axle rotate, and driving cuts native unit in the presence of hydraulic motor 10 on potato ridge
Both sides of the edge are respectively cut out together " ditch ", to reduce the resistance and upper soil pressure of excavating gear 2, while cut-out seedling vine, weeds are played,
Reduce the effect of later stage potato seedling separation screening burden；The excavating depth of the excavating gear 2 collected is fed back to liquid by sensor 34
Pressure control system, stretches, and then pass through first crossbeam 3, longeron by the way that hydraulic control system regulation hydraulic cylinder 31 is different degrees of
16 and second cross beam 15 drive firming adjustment unit adjusted according to excavating depth and keep certain pressure to be attached to potato ridge surface,
To crush soil block.
Before harvest, set first in excavating depth scope, the application, the device is to excavate deep for potato planting agronomy
Range set is spent in 200-300mm.When sensor 34, which detects actual excavation depth, exceedes the maximum digging depth of setting, pass
Sensor 34 passes it to hydraulic control system, and the expansion link of hydraulic control system control hydraulic cylinder 31 shrinks, under drive
Frame is moved up so that excavating depth shoals, and suspension bracket 17 is close to the lower end of nut 27, and linking arm 19 is around the second bearing pin 24
Rotate up, the forward upward of press wheel 20 movement, adjustment frame 18 is moved forward, the second adjustment linked together with adjustment frame 18
