Abstract: A device for feeding sheet material into a granulator and particularly scrap plastic sheet material of the type wherein a plurality of such sheets are normally twisted together to form a composite rope which is fed between opposed feed rolls and subsequently into a granulation chamber. The present feed device includes a pair of cooperating rolls, each of which is provided with a plurality of longitudinally spaced, radially inwardly extending grooves. The grooves of each roll are adapted to mesh or interdigitate with a resultantly formed ridge on the opposing roll such that the sheet material fed therebetween is forced into a sinuous cross sectional configuration and subjected to differing roll surface velocities. Both of the above-described conditions imparted to the sheet material are believed to contribute to trouble free positive feeding especially when feeding individual, i.e. single sheet material thicknesses.

Abstract: In a forage harvester having a rotatable cutterhead and adjacently-positioned shearbar, an upper feed roll assembly comprising at least one upper feed roll mounted above and forwardly of the shearbar for movement by a pair of arms. A lower feed assembly cooperates with the upper feed roll assembly to convey crop material to the cutterhead across the shearbar. A tensioning assembly is coupled to the mounting arms for upper feed roll. First and second positions of the tensioning assembly provide a first condition in which the upper feed roll assembly is biased toward a lower operative position adjacent the cutterhead and shearbar and a second condition in which the bias on the upper feed roll assembly is relaxed, permitting movement to an upper inoperative position generally remote from the cutterhead and shearbar to thereby expose and render the shearbar readily accessible for servicing.

A lower feed assembly cooperates with the upper feed roll assembly to convey crop material to the cutterhead across the shearbar. A tensioning mechanism is coupled to mounting arms for the upper feed roll assembly. First and second positions of the tensioning mechanism provide for a first condition in which the upper feed roll assembly is biased toward a lower operative position adjacent the cutterhead and shearbar and a second condition in which the bias on the upper feed roll assembly is relaxed, permitting movement to an upper inoperative position generally remote from the cutterhead and shearbar to thereby expose and render the shearbar readily accessible for servicing. In the second condition the tensioning mechanism spring is fully compressed and used to directly transfer force used to lift the upper feed roll assembly.

Abstract: A tire is placed upon an infeed support which initiates movement of a spindle to extend longitudinally through the tire, then expand radially to engage the tire beads and then retract longitudinally to clamp the beads together. One of a pair of power driven rolls having roughened, wear resistant surfaces, then is moved toward the fixed roll of a pair to grip the tire between them and rotate the tire and spindle assembly. The spindle and drive roll assembly, together with the rotating tire, then is moved by a common support carriage toward a rotary flywheel type cutter assembly which operates on the tire in the radial direction inward from the tread area to an area closely adjacent the metal beads, reducing the tire to small pieces. An air fan is integrated with the flywheel of the cutter assembly to minimize heating of the flywheel and cutter mechanism. A metal sensor on the infeed support prevents operation of the apparatus if the tire contains steel belts.

Abstract: Harvested crop material is fed to the cylindrical cutter-head of a forage harvester by a feeding assembly consisting of opposed pairs of upper and lower feed rolls. The articulated upper roll assembly floats to accommodate variations in the flow of crop material. The downstream upper feed roll is carried on a pair of opposite radius arms which are rigidly coupled by a transverse leveler shaft, providing a stable frame and minimizing cocking or twisting of the roll. A second pair of feed roll arms is pivotally connected to the radius arms and extends forward to support the upstream feed roll which is journaled on a shaft rigidly connected between the feed roll arms. A stop and biasing arrangement provides that each upper roll may float independently, the articulation of the feed roll assembly being such that upward movement of either roll or the rolls together is subject to the restoring force of a tension spring.

Abstract: A forage harvester has a rotary cylinder type cutterhead mounted in a housing with opposite side walls, crop material being fed into the cutterhead in a generally radial direction over a shear bar adjacent the cutterhead periphery. The shear bar is mounted for fore and aft adjustment toward and away from the cutterhead periphery to maintain the optimum clearance between the cutterhead and the shear bar by means of a mechanism that includes a pair of bell cranks respectively pivotally mounted to support members on the opposite walls, with one end of each bell crank being connected to the shear bar through a fore and aft link while the other end of the bell crank threadably receives the threaded portions of a vertically elongated rod that is rotatably supported adjacent the housing side wall and has an easily accessible head adjacent the top of the housing, whereby rotation of the rod causes the bell crank to rock on its pivot to cause linear fore and aft adjustment of the shear bar.

Abstract: A forage harvester has a cutterhead housing with a rotary reel type cutterhead mounted therein, the cutterhead having a plurality of knives parallel to the cutterhead axis at the cutterhead periphery, the knife edges generating a cylinder as the cutterhead rotates. The cutterhead reduces crop material that is fed into the housing and discharges the reduced material through a discharge opening to a conveying system that conveys the crop material to a crop-receiving vehicle. Removably mounted over the discharge opening is a recutter screen that has an arcuate shape generally concentric with and adjacent to the cutterhead periphery and a plurality of elongated apertures, each aperture having parallel longitudinal edges that extend diagonally relative to the knife cutting edges.

Abstract: This invention relates to size reduction apparatus and particularly to a novel feed device thereof and method of feeding sheet material thereto. A first baffle is adapted to extend into the cutting chamber simultaneously towards the cutting rotor and a downstroke wall portion from which a bed knife is adapted to extend into cutting contact with knife means mounted on the rotor. Such construction, in effect, enables the simultaneous formation of a variable width sheet feed opening to the granulator as well as means for restraining a portion of already granulated material on the upstroke side of the rotor from contacting the sheet material as it is fed between the rotor and bed knife. A secondary baffle may in turn be disposed in contact with the first baffle so as to close a secondary or housing opening disposed between the first baffle and a pair of upwardly spaced feed rolls.

Abstract: The present disclosure relates to a knife construction adapted for positioning within cut out seat portions of a rotor. The base of the knife is provided with a downwardly extending relatively narrow leg at the front face thereof which is adapted to engage base portions of the rotor seat so as to form an area of high sealing contact between the engaging surfaces and thus prevent liquified, i.e. fluid acting under high pressures, plastic material from flowing underneath the knife and thus undesirably altering its position vis-a-vis the rotor. A further embodiment includes an elevated or stepped pad forming the seat for receipt of the knife, the stepped or elevated front face of the pad forming a continuation of the blade face of the knife so as to distribute the forces imparted by such liquified plastic material over a larger combined area and thus reduce the force thereof upon the knife/seat interface.

The cutting head is used in combination with a material infeed mechanism that maintains a steady, positive feed of material to reduce the elastomeric material into uniform small chunks that can be used for fuel, or otherwise more readily disposed than the present large size tires or similar articles.

Abstract: The cutting cylinder has knife segments extending across its periphery in a staggered pattern so that each row winds essentially helically from end to end of the cylinder, thereby providing an effective shearing action as the knife segments cooperate with a stationary shear bar to sever incoming crops into countless short lengths. Air and crop cups located directly below the knife segments capture the short lengths before they can enter the interior of the cylinder and sweep the same through the cutting chamber, blasting them out the discharge spout without the assistance of an auxiliary fan. By keeping the elongated cups substantially parallel to the axis of rotation of the cylinder and perpendicular to the path of travel of the entering crops, regardless of whether the cutting edges of the knife segments are arranged parallel to or slightly oblique to the axis of the cylinder, the full thrust of the spinning cylinder is utilized to propel the crop pieces up the spout for maximum efficiency.

Abstract: The present disclosure relates to a size reduction apparatus such as a granulating machine of the type for cutting plastics and the like. The granulating machine includes a chamber provided with a driven rotor having a plurality of cutting elements mounted on the periphery thereof, each cutting element having in turn a plurality of spaced cutting knives. The cutting knives cooperate with stationary bed knives to comminute materials fed into the cutting chamber. The downstroke side of the cutting chamber is further provided with an access opening normally closed during cutting operations by a cover, which may be of particularly heavy slotted construction and which provides a backup surface for the material being comminuted. The disclosed granulating machine is particularly useful in comminuting large chunks of plastic material such as heavy purging, thick sheet and cast blocks. Machines of this type are designated as hog type granulators in the industry.
