The purpose of the utility model is realized like this: a chopper with a bundle breaking screw cone and a cutting knife wheel comprises a runoff straw cutter or an axial-flow grass cutter provided with a side inlet, wherein a chopper with the bundle breaking screw cone and the cutting knife wheel is arranged at the end of a grass cutting roller extending out of the side inlet of the runoff straw cutter or the end of an impeller extending out of a feed inlet of the axial-flow grass cutter, a foldable material supporting disc is hinged at the lower part of the outer port of a feed channel connected with the side inlet or the feed inlet, the structure of the chopper is that spiral wales are uniformly distributed on the conical surface of the bundle breaking screw cone, the cutting knife wheel is fixedly connected at the rear end of the bundle breaking screw cone, the cutting knife wheel is uniformly distributed on a hub and mutually cross-shaped knife rests, the knife rest surface of each knife rest forms an inclined included angle with the axis of the cutting knife wheel, one side of the inclined knife rest surface is provided with connecting seats uniformly distributed along the long edges of the knife rests, upright cutting knives are respectively and fixedly connected on the connecting seats through bolts, the tooth-shaped cutting knives of the uniform distribution are parallel to each other, the knife surfaces are vertical to the long edges of the knife rest, the cutting edges are fixedly connected to the other side of the knife rest surface and extend out of the long edges of the knife rest, and the cutting knives are parallel to the long edges of the knife rest.

The utility model discloses can break open the bale that gets into, tie the rope and cut off, the straw splits, cuts up, also can split open, cut up the long corn stalk who gets into, can also install and use on other meadow grass machine, not only can improve other meadow grass machine work efficiency and effect, can save manual work and intensity of labour moreover equally. When the utility model is used for processing pasture or straw, the material supporting disc is firstly opened (the material supporting disc has two functions, namely, a feed inlet which can be covered by the material collecting disc is a cover disc, and a material supporting disc with supporting legs is opened). When the material supporting plate is opened and horizontally placed, power is input by a tractor or a motor, the machine rotates, the rotation speed required by high speed is increased from low speed, the pre-placed straw bundle on the material supporting plate is pushed into a chopper, under the action of the chopper, the straw bundle is screwed in and broken by a rotating bale breaking screw cone, when the straw bundle enters a tooth-shaped cutting knife, the straw bundle rope is cut off by the rotating tooth-shaped cutting knife, then the cut straw bundle rope is pulled out by hand, and at this time, the straw also continuously enters inwards, and the transversely entering straw is cut off by the tooth-shaped cutting knife and the crude straw is split.

The utility model discloses rational in infrastructure, easy operation when smashing the forage grass, has realized breaking bundle, cutting rope, splitting grass, cutting up to the bale, has improved crushing efficiency and effect, has saved the manual work, has reduced workman intensity of labour, has improved the security performance.
