Abstract
This invention is a separator-conveyor that uses a scissors action to cut stems, roots, vines and other debris from a crop being harvested and processed. This is accomplished by providing a plurality of multi-sided rollers having sharp edges disposed alternately at an angle to adjacent rollers causing a scissors type cutting action that starts at one end of such rollers and continues to the other end. A plurality of the scissors action separator-conveyors can be used in conjunction with drying systems on a crop harvester-processor. This harvester-processor allows root crops such as peanuts to be harvested, cleaned, dried and graded in one continuous operation.
Claims16
The method of harvesting root type crops comprising:
- passing the crop through a crop intake of a harvester-processor:
- conveying said crop across at least on separator-conveyor including a plurality of multi-sided cylindrical rollers having sides intersecting at sharp corners that are mounted alternately at an angle to an adjacent roller at a distance that allows scissors action cutting contact between the sharp corners of the adjacent rollers as they are rotated to remove dirt, stems, roots, vines, and other debris from the crop;
- and passing the crop through at least one drying area to reduce moisture content to a marketable level.
A separator-conveyor for separating a crop into desirable product and undesirable material comprising:
- a support frame having laterally spaced sides;
- a plurality of cylindrical rollers including a first set and a second set, said rollers being rotatably supported on said sides of said support frame in longitudinally spaced alternating order and having rotational axes in parallel spaced relationship, said first set having rotational axes in a first plane and said second set having rotational axes in a second plane inclined with respect to said first plane, said cylindrical rollers being multisided with adjacent sides thereof intersecting at a corner, the longitudinal spacing between adjacent rollers establishing a cutting action between adjacent corners;
- and
- means for cojointly rotating said first set and said second set whereby a crop fed onto said rollers is rotated and fed therealong with said desirable product being separated from said undesirable material by said cutting action.
The method of harvesting root type crops comprising the steps of:
- removing the above ground foliage from the crop;
- digging said crop;
- conveying the crop across a separator-conveyor including two sets of multisided rollers mutually inclined in alternating order to establish a scissors type cutting action therebetween as said rollers are rotated whereby dirt, stems, roots, vines and other debris can be removed from the crop being harvested;
- and transferring said crop from the separator-conveyor for further processing.
