Abstract
An auger cutter, windrower and conditioner for standing crops such as hay, a cutter and a feed mechanism for feeding forage harvesters crops such as corn and sorghum, including a cutter auger with cutting teeth attached to the auger flight and a conveyor auger to move the cut crop to a central area to be discharged as a window or as a mass of material to be fed to a second crop processing device such as a forage harvester.
Claims29
A crop processor comprising:
- a support frame coupled to a prime mover;
- a drive system for said processor connected to and powered from said prime mover;
- at least two conveyor augers on a common axis, each including a helical flange thereon, each conveyor auger supported in cantilever fashion on said support frame at opposite ends thereof, each of said conveyor augers being less than half the width of the processor, the helical flange of each conveyor auger wound to move the material toward the center of the processor;
- conveyor auger housings cooperating with said conveyor augers to move the material;
- at least two cutting augers on a common axis;
- support means for each of said cutting augers at the ends and at the center of the processor;
- each of said cutting augers having a helical flange therearound with the flange from the outside turned in the same direction as the conveyor flange for at least a portion of the length of the conveyor auger and a continuation reversely turned flange for the remaining length of the cutting auger to the center of the processor;
- each of said flanges including a plurality of first means for mounting cutting teeth thereon;
- a plurality of cutting teeth;
- second means for mounting each of said cutting teeth to a single one of said first mounting means on said flanges;
- a front cover means pivotally attached to said support means;
- a rear cover means;
- a baffle means attached to and extending from said conveyor auger housing enlarging the volume for conveying the cut crop;
- a center discharge area to discharge cut crop to the rear of said processor;
- means for selecting and maintaining the height of the cutting augers above the ground;
- and
- whereby the crop is cut by the cutting augers and fed by the conveying augers to the center area for discharge.

A crop processor comprising:
- a support frame coupled to a prime mover;
- a drive system for said processor connected to and powered by said prime mover;
- a second crop processor integral with said prime mover a first crop processor including;
- .
- at least two conveyor augers on a common axis, each including a helical flange thereon, each conveyor auger supported in cantilever fashion on said support frame at opposite ends thereof, each of said conveyor augers being less than half the width of the first processor, the helical flange of each conveyor wound to move the material toward the center of the first processor;
- at least two cutting augers on a common axis, each of said cutting augers having a helical flange therearound with the flange from the outside turned in the same direction as the conveyor flange for at least a portion of the length of the conveyor auger and a continuation reversely turned flange for the remaining length of the cutting auger to the center of the processor;
- each of said flanges including a plurality of first means for mounting cutting teeth thereon;
- a plurality of cutting teeth;
- second means for mounting each of said cutting teeth to said first mounting means on said flanges;
- a front cover means pivotally attached to said support means;
- a rear cover means;
- a baffle means attached to and extending from said bottom housing enlarging the volume for conveying the cut crop;
- a center discharge area to discharge cut crop to the rear of said processor;
- a power discharge means in said center discharge area to compress and force the material cut by the processor from said central discharge area;
- and
- means for selecting and maintaining the height of the cutting augers above the ground, whereby the crop is cut by the cutting augers and fed by the conveying augers to the center for discharge.
13 more elements
A crop processor comprising:
- an auger having flighting therearound;
- support means for said auger;
- drive means for rotating said auger;
- teeth for attachment to said flighting on said auger;
- and
- means for attaching said teeth to said flighting, each of said teeth including a metal base plate of essentially horse shoe shape, having a circular portion and converging side portion, a hole toward the circular end of said base plate for attaching to said auger flighting, said base plate having bevels on a major portion of a first flat surface, the base plate being bent in the direction of said first flat surface, and the second flat surface of the base plate being hard surfaced only on the converging side portion.
