Abstract

A harvesting aid for fruit, particularly vine-borne fruit such as grapes, includes a steerable, self-propelled vehicle configured for straddling the row and supporting workers on either side of the vines. Workers sever the fruit and deposit it on a conveyor assembly which moves the fruit to a discharge point. The conveyor assembly includes a right angle conveyor segment for changing the direction of the movement of the fruit. Workers on one side deposit fruit directly onto a conveyor belt. Workers on the other side deposit fruit onto downwardly sloping pivotal diverter plates, positioned along the center line of the vehicle, having lower, outer ends above the conveyor belt. The diverter plates pivot out of the way when a vine trunk or stake is encountered as the vehicle moves down a row in either direction. The wheels of the vehicle are independently steerable over at least 90.degree. for maneuverability and for allowing the vehicle to maintain a constant azimuthal orientation.

Claims5

Dependent claims

A method for harvesting fruit from rows of plants comprising the following steps:

directing a self-propelled vehicle in a first direction along a first row of plants from a first row end to a second row end, the vehicle straddling the first row and pointing in a chosen direction as the vehicle leaves the second row end of the first row;
positioning a working on the vehicle on each side of the row;
removing the fruit by the workers from the plants;
depositing the removed fruit onto a conveyor;
conveyor the removed fruit to a discharge point on one side of the vehicle;
substantially stopping the vehicle once the vehicle passes the second row end;
moving the vehicle in a second direction generally perpendicular to the first direction;
substantially stopping the vehicle when the vehicle is aligned with the second end of a second row;
directing the vehicle in a third directon along the second row from the second row end to the first row end of said second row with the vehicle straddling the second row;
keeping the vehicle pointed in the chosen direction during the first substantially stopping step, the moving step, the second substantially stopping step and the directing step so the discharge point is on the same side of each of said rows;
and
repeating the fruit removing, depositing and conveying steps.
