Described band returning straw into field and rotary cultivation fertilising corn drill also comprises press wheel, and described press wheel is positioned at seeding unit rear, has sowed rear kind of a ditch gently to be pressed.
Rotary blade on flail knife and rotary tillage rotor on described straw-returning rotor all adopts compartment to arrange, only the band of needs sowing is carried out to straw-returning and rotary tillage process.
Described frame is connected with the three-point hitch of tractor.
The side of described gear box I and straw-returning cutter shaft is equipped with belt wheel, and belt wheel is with connection by V.
Described gear box II is sent to rotary ploughing cutter shaft by the gear-box of below by power.
Described disc type seeder rear is also provided with covering device.
Described band returning straw into field and rotary cultivation fertilising corn drill also comprises three sprocket wheels, on described press wheel and fertilizer apparatus, is equipped with sprocket wheel, and press wheel is connected with three sprocket wheels by chain respectively with the sprocket wheel on fertilizer apparatus.
Described band returning straw into field and rotary cultivation fertilising corn drill also comprises bigeminy sprocket wheel, and disc type seeder is provided with sprocket wheel, and bigeminy sprocket wheel is connected with the sprocket wheel on three sprocket wheels and disc type seeder by chain respectively.
Rotary ploughing cutter shaft axle center is lower than the axle center of straw-returning cutter shaft.
The beneficial effects of the utility model: the advantage of this utility model is: low in energy consumption, production efficiency is high, sow effectively, can effectively reduce that soil structure that rotary tillage causes destroys and tractor destroys soil packing.
