Abstract
A disc type chipper/mulcher having multi-blade flails in which two or more blades are attached to a sleeve, and the blade/sleeve combination pivots about a post as a single unit. The flails are sharpenable and reversible, and can be mounted on the same side of the disc as the knives. The chipper/mulcher may also include disc mounted fan blades and a screen for governing the size of the processed materials.
Claims27
A chipper/mulcher comprising:
- a rotary disc having a first side;
- a plurality of knives positioned on said first side for reducing materials fed toward said first side;
- and
- a flail comprising a plurality of substantially flat sharpened members spaced from one another and extending from a sleeve, said flail pivotally coupled to said first side.
A chipper/mulcher comprising:
- a housing having an interior;
- a rotary disc positioned within said housing, said rotary disc operatively dividing said interior between a chipping side and a mulching side;
- a knife and a first pivotable flail coupled to said disc on said chipping side;
- a second pivotable flail coupled to said disc on said mulching side, said first and second flails each comprising a sleeve and a plurality of substantially flat sharpened members extending from said sleeve.
In a chipper/mulcher having a frame, a housing attached to the frame, a motor attached to the frame, and a disc rotatably mounted to the frame and housed within the housing, said disc made to rotate by said motor, and said disc having attached thereto on at least one side thereof a plurality of knives and flails, the improvement comprising said flails having a plurality of sharpened blades fixedly attached to a hollow sleeve which is rotatably attached to a post, said post is fixedly attached to, and extends outwardly from, said disc, such that as said disc is rotated, said sleeves pivot about said posts, causing said flails also to pivot.
In a chipper/mulcher having a frame, a housing having an interior attached to the frame, a motor attached to the frame, at least one opening in said housing for receiving reducible material, and a disc rotatably mounted to the frame and housed within the housing, said disc operatively dividing said interior between a chipping side and a mulching side and made to rotate about an axis of rotation by said motor, and said disc having positioned on at least one side thereof a plurality of knives and flails, the improvement comprising said flails having a plurality of sharpened blades, said knives positioned on the same side of the disc as at least one of said flails, and said knives extending a greater distance away from said disc than said same-side flails.
A chipper/mulcher comprising:
- a rotary disc having a first side;
- a plurality of knives positioned on said first side for reducing materials fed toward said first side;
- and
- a flail pivotally coupled to said first side, said flail comprising a sleeve and a plurality of substantially flat sharpened members fixedly mounted on and extending from said sleeve.
