the cutting mechanism (Z) moves and cuts in a farmland for planting soybeans, the root pressing roller (Q) is driven to roll through the roller (C) in the cutting process, so that the upper end of a soybean rod is extruded downwards, the root of the soybean rod is contacted with the offset plate (Z78), the traction elastic rods (Z74) on two sides exert pressure to draw elastic force, so that the angle of the offset plate (Z78) is changed, elastic shaking is further carried out, soil in the farmland is shaken down from the drain hole (Z76), meanwhile, the blocking piece (Z71) extends out of the offset plate (Z78) to block the soil, and the contact between the soil and the cutting mechanism (Z72) is reduced, then the half-tooth rotating wheel (2 s) rotates in the tooth frame (2 w) so as to drive the tooth frame (2 w) to repeatedly move left and right, at the moment, the sliding cutter (2 h) repeatedly moves at the upper end of the fixed cutter (2 v), so that the cutting force is generated between the sliding cutter (2 h) and the fixed cutter (2 v) to cut the root of the soybean rod, a gap is generated between the sliding cutter (2 h) and the fixed cutter (2 v) in the cutting process, at the moment, the soil at the front end of the gap is blocked by the shielding frame (k 7), meanwhile, the soil impacts the shielding frame (k 7), the telescopic hose (k 4) stretches and contracts due to the extrusion force to generate air pressure, the air pressure pushes the opening and closing piece (k 2), the opening and closing piece (k 2) rotates forwards around the torsion shaft (k 9) to open, the soil at the front end is sprayed, the soil is prevented from staying at the front end of the shielding frame (k 7), the soil is prevented from being blocked in the shell (2 x), and therefore the soybean stem root is effectively cut between the sliding cutter (2 h) and the fixed cutter (2 v); after the soybean pole cutting is accomplished, roll the soybean from the soybean pole through the roll of root pressing roller (Q), at this moment bull stick (z 22) rotate and make helical blade (z 29) carry the soybean, bull stick (z 22) are carrying out pivoted in-process simultaneously, clamp plate (c) rotate with soybean shell, extrusion contact takes place for clamp plate (c) and soybean shell, extrusion in-process clamp plate (c) applys reverse extrusion force to trace (z 26), at this moment trace (z 26) are carried out the interlock and are made articulated sliding block (z 24) carry out direction elasticity slip on direction elastic rod (z 21), thereby make cushion between clamp plate (c) and the soybean shell, avoid clamp plate (c) to crush the soybean of inside when crushing the soybean shell, ball (t) in the clamp plate (c) outside roll simultaneously, not only provide sliding force for clamp plate (c) in the in-process of rolling, can rotate extrusion to the soybean shell, accelerate soybean shell to break, discharge inside soybean shell, make soybean shell and soybean card separate from extrusion nozzle (m), avoid blowing out the soybean shell from the inside, blow out the soybean shell from the surface.
