Abstract

Device for eliminating oversize pellets from balling disks, includes a plow-like tool defined by a series of cylindrical rods that are coplanar and parallel to each other and incorporated into a horizontal plate, whose medial portion incorporates a vertical tubular arm that protrudes vertically and upwards to pass axially through and be selectively and adjustably attached to a vertical sleeve that is incorporated in a distal portion of an extensible arm, which composes a trussed structure that is adjacently attached to a balling disk and protrudes over its area of operation.

Claims (7)

1. Device for eliminating oversize pellets from balling disks, said device comprising

a plow tool including

cylindrical rods that are coplanar and parallel to each other and incorporated into a horizontal plate,

the horizontal plate incorporating a vertical tubular arm in a medial portion, the vertical tubular arm protruding vertically and upwardly axially into and through a vertical sleeve so as to be selectively and adjustably attached to the vertical sleeve,

the vertical sleeve being incorporated into an extremity portion of an extensible arm of a fixed trussed structure adjacently fixedly attached to a balling disk and the extensible arm protruding over an area of operation of the balling disk,

said vertical sleeve being provided with at least two internally threaded radial bores having screwed corresponding clamp bolts extending radially through said radial bores of said vertical sleeve with said clamp bolts operating directly and radially on the vertical tubular arm of the plow tool, and with the vertical tubular arm being axially slidable within and through the vertical sleeve for fixing of a positioning of the plow tool with respect to the balling disk so that the rods and plate together move vertically and angularly in relation to a plane of the balling disk and with respect to the fixed trussed structure until locked in position by the clamp bolts.

2. Device for eliminating oversize pellets from balling disks in accordance with claim 1 , wherein the extensible arm is adjacently attached to the balling disk.
