摘要:
A crop cleaner comprising a generally parallel array of first and second rollers each first roller being scrolled and each second roller generally unscrolled, the first rollers alternating with second rollers with pairs of adjacent rollers being carried on frames with each frame being displaceable relative to an adjacent frame and a drive for independently rotating each pair of rollers.

A cleaning table for sorting newly harvested potatoes or other vegetables from vines, dirt, clods, rocks and other debris. The table includes a deck comprised of a plurality of spaced apart, parallel longitudinal rollers that operate in pairs of counterrotating rollers which rotate toward one another when viewed from the top. The rollers are formed of an elastically deformable material such as rubber, soft plastic or the like. One of each pair of rollers can have an elongate helical rib or flight extending from end to end. As potatoes and associated debris move longitudinally along the rollers, the dirt, vines, clods and other debris are separated from the potatoes and fall between the spaces between the rollers. Hard objects pass between the rollers without damage to the rollers.
摘要:
An improved root crop harvester having a narrow and compact processing chassis adapted to simply and easily receive header assemblies of differing capacities. The header assemblies include a transverse roll conveyor for gathering roots received from the digger wheels into a stream for discharge through a central opening in the transverse conveyor to a fore-and-aft extending roll conveyor carried by the processing chassis. The fore-and-aft roll conveyor is inclined upwardly from front to rear to increase the scrubbing and tumbling action and is also provided with a reversing roll section at its rearward end to discharge the roots to the side. The fore-and-aft conveyor is also sloped across its width at its rearward end to aid in discharging roots transversely to the roll conveyor length. The conveyors on the processing chassis are carried between the support wheels to reduce side drafts, minimize wheel slippage in wet field conditions and improve transport maneuverability.

A cleaning conveyor is illustrated as part of a beet harvester and includes a plurality of transversely extending elongated rollers which move the beets laterally to feed into a vertical auger conveyor. At the vertical auger end, the forwardmost and rearwardmost cleaning rollers are yieldably mounted and the cleaning conveyor is positioned relative to the vertical auger conveyor so that the flow of beets into the vertical auger conveyor is unobstructed by dirt and mud buildup above the cleaning rollers or by the repelling force of the rotating vertical auger.

Sizing screen apparatus is provided with mechanism for enabling the extent of spacings, longitudinally of an elongate sizing screen between transversely extending, individual rows of spacing members, to be adjusted individually. Each transversely extending row of sizing members is mounted on a rotatable shaft journaled at its opposite ends in the lower end portions of a pair of mounting arms that are pivoted at their upper end portions to opposite longitudinal side members of a supporting frame and hang downwardly for back and forth space adjusting movement. The mounting arms of the pair are pivotally interconnected adjacent their lower ends with an elongate connection member of an operating device that is manually or power operated. The connection is made by preferably a pair of rods at opposite sides, respectively, of the sizing screen and having one set of corresponding ends pivotally attached to the respective mounting arms of the pair and the set of opposite ends fixedly attached to the connection member of the operating device in a length adjustable manner, as by providing such opposite ends with screw threading, passing them through respective bracket members of a series of same that are immovably affixed to the connection member, making the lengthwise adjustment by screwing a set of lock nuts at opposite sides of such bracket members, and tightening such lock nuts to lock the adjustments in place.
