Abstract
A forage chopping and propelling device including a casing having an inclined bottom and disposed therein a chopper rotor and a booster impeller that operate as an integrated assembly to receive forage from an inlet, chop the forage and eject the chopped forage out a discharge chute. The forage travels along a rectilinear path from the inlet to the discharge chute and undergoes recutting by at least one recutting bar disposed between the chopper rotor and the booster impeller.
Claims11
A forage chopping and propelling device comprising, in combination:
- a. a casing having an inlet at one end, a discharge chute at the other end and a bottom section that is inclined from the discharge chute to the inlet;
- b. means for feeding the forage into the inlet of the casing;
- c. a chopper rotor having a first axis of rotation disposed within the casing for chopping the forage fed into the inlet thereof;
- d. means disposed between the feeding means and chopper rotor for cooperation with the chopper rotor in chopping the forage;
- e. a booster impeller disposed within the casing adjacent the chopper rotor for receiving the chopped forage directly from the chopper rotor and propelling the chopped forage through the discharge chute, said impeller having a second axis of rotation spaced from and parallel to the first axis of rotation to provide rectilinear movement of the forage from the inlet of the casing to the discharge chute;
- and
- f. at least one recutting bar adjustably mounted to the casing and disposed between the first and second axes of rotation for further cutting the forage chopped by the chopper rotor.
