Potato cleaning table
First Claim
1. A cleaning table assembly for separating newly harvested vegetables from associated debris, comprising:
- a cleaning table having a deck inclined from a first end downward toward a second end including a plurality of parallel spaced apart cleaning rollers assembled in generally coplanar relationship, and means for rotation of the rollers;
conveyor means having a material discharge end poised over the first end of the cleaning table deck for discharge of vegetables and associated debris onto the cleaning table deck proximate the first end thereof for discharge of the vegetables from the cleaning table deck off of the second end thereof;
connecting means connecting the cleaning table to the conveyor means, said connecting means including pivot means pivotally connecting a first portion of the conveyor means proximate the discharge end to a first portion of the cleaning table, and adjustable linkage means connected between a second portion of the conveyor means upwardly spaced from the first portion and a second portion of the cleaning table upwardly spaced from the first portion whereby the inclination of the cleaning table deck is adjustable by adjustment of the adjustable linkage means.

Abstract
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.

13. A cleaning table assembly for separating newly harvested vegetables from associated debris, comprising:
-
a cleaning table having an inclined deck including a plurality of parallel spaced apart cleaning rollers assembled in generally coplanar relationship, and means for rotation of the rollers, a frame having longitudinal side members and a forward transverse member and a rearward transverse member, said rollers being connected between the forward and rearward transverse frame members parallel to the longitudinal side frame members, a first side plate extending upward from a first of said longitudinal side frame members, a second side plate extending upward from a second of said longitudinal side frame members, a transverse brace extending laterally across the top of the frame and connecting the first and second side frame members; conveyor means having a conveyor means housing, and a material discharge end for discharge of vegetables and associated debris onto the cleaning table deck proximate a first end thereof for discharge of the vegetables from the cleaning table deck off of a second end thereof with the deck inclined downwardly from the first end toward the second end; connecting means connecting the cleaning table to the conveyor means with said discharge end of the conveyor means poised over the first end of the cleaning table deck, said connecting means including pivot means pivotally connecting a portion of the conveyor means to a portion of the cleaning table, and adjustable linkage means comprising a first turnbuckle assembly connected to said transverse brace at one end and connected to the conveyor means housing at the other end, a second turnbuckle assembly connected to the transverse brace at one end and connected to the conveyor means housing at the opposite end, said pivot means including a pair of brackets each secured at one end to the conveyor means housing and pivotally connected at the opposite end to the cleaning table proximate the first end thereof whereby the inclination of the cleaning table deck is adjustable by adjustment of the adjustable linkage means. - View Dependent Claims (14)
