Abstract
Abstract A plant picking and boxing apparatus is mounted on a wheeled frame and includes an engine for driving the wheeled frame by a hydraulic system. Parallel mounted endless belts are supported on the frame and grip tomato plants, or the like planted in rows, and transport the plants into a loading mechanism. The plant roots are cleaned by rotatable, flexible flaps hitting the roots of the plants being transported between the parallel belts. The loading box has microswitch to determine when it is filled and ready for shifting to a second box, and to allow the plants to be pushed from the loading box into a packaging container where they can be placed on a conveyor and be conveyed to a closing platform on the wheeled frame.

The machine in accordance with claim 7 in which said power source is operatively connected to hydraulic pumps generating hydraulic pressure for driving said wheeled frame and for operatively driving said parallel mounted endless belt means and said loading box means responsive to controls from a central control box.
Claim 14
Dependent Claim
126 words
In a plant pulling and packing machine having a wheeled frame and a plant pulling and conveying means attached to said wheeled frame for picking plants from the earth and transporting the plants for packaging, wherein the improvement comprises in combination therewith: a plant packing magazine located adjacent one end of said plant conveying means for receiving plants being picked and conveyed, said packing magazine having a receiving container and a backing plate located therein whereby received plants in said magazine are compressed against said backing plate; backing plate actuating means attached to said backing plate for shifting said backing plate in said magazine responsive to predetermined pressure thereagainst by plants being received therein; and means for removing said plants from said magazine into packaging containers.
Claim 15
Dependent Claim
126 words
In a plant pulling and packing machine having a wheeled frame and a plant pulling and conveying means attached to said wheeled frame for picking plants from the earth and transporting the plants for packaging, wherein the improvement comprises in combination therewith: a plant packing magazine located adjacent one end of said plant conveying means for receiving plants being picked and conveyed, said packing magazine having a receiving container and a backing plate located therein whereby received plants in said magazine are compressed against said backing plate; backing plate actuating means attached to said backing plate for shifting said backing plate in said magazine responsive to predetermined pressure thereagainst by plants being received therein; and means for removing said plants from said magazine into packaging containers.
Claim 16
Dependent Claim
