Abstract
A chopper mechanism for chopping stalk-like plant wherein the chopper mechanism includes a plurality of chopping elements that are removably mounted on the pair of chopper drums via associated holders. The chopping elements are mounted on the chopper drums circumferentially spaced apart and define a predetermined radial angle (α) therebetween. Each of the chopping elements having a pair of substantially parallel cutting edges spaced apart by substantially parallel mounting surfaces. One of the cutting edges is selectively engaged in the chopping while the other cutting edge is enclosed within the holder. The parallel cutting edge of the chopping elements facilitates in reversing each chopping element depending on the degree of abrasion of the cutting edge.
Claims10
A chopper mechanism for chopping stalk-like plants, the chopper mechanism comprising:
- a plurality of chopping elements having a pair of spaced apart substantially parallel cutting edges and mounting surfaces substantially perpendicular to the cutting edge, each of the cutting edges being along the plane of at least one of the mounting surfaces, each of the cutting edges being selectively engaged in chopping;
- a plurality of chopper drums defined by a plurality of positioning provisions circumferentially spaced apart;
- and
- at least one holder cooperating with each of the positioning provisions, the holder defining a profiled recess to removably mount the chopping element there within via the mounting surfaces along a mounting plane (A), at least one of the cutting edges adapted to be enclosed within the holder,
- wherein each of the adjacent chopping elements adapted to define a predetermined radial angle (α) therebetween.
