The invention belongs to the technical field of agricultural
tillage whole machinery, particularly relating to a rotary-
cutting and turning type ploughing in green device of
green manure, which comprises a rotary soil-
cutting unit and a soil discharging and green burying unit, wherein, the rotary soil-
cutting unit and the soil discharging and green burying unit are mounted with a certain angle therebetween; the rotary soil-cutting unit comprises two side cutters and a transverse cutter which is Y-shaped and the included angle of which is not larger than 170 degrees; and the soil discharging and green burying unit comprises two lateral plates and a top roll. The device is suitable for the ploughing in
green operation of
milk vetch, hairy vetch, common vetch, white clover,
red clover and other
green manure crops. Particularly, the rotary soil-cutting unit can
cut the soil on which
green manure crops grow into rectangular furrow slices, the furrow slices are turned over by 180 degrees under the auxiliary action of the soil discharging and green burying unit, thereby the green
manure crops are buried into the soil, the
spreadability of ploughing in green of the green
manure is good, thereby the use ratio of the green
manure is greatly improved.
