Abstract

In a tomato field in which the tomato plants are grown in a plurality of substantially parallel rows an apparatus is advanced along a predetermined one of the rows. The apparatus cuts the tomato plants in the row, carries the cut plants rearwardly and discharges them onto a transverse conveyor. The transverse conveyor transfers and deposits the cut plants laterally onto a parallel row of uncut plants in a row located at a predetermined distance from the row being cut, thereby uniting two rows of plants for subsequent harvesting by a mechanical tomato harvester.

Claims3

Dependent claims

Apparatus for facilitating the harvesting of tomatoes comprising:

a. a fore and aft frame;
b. means for supporting said frame on the ground as said apparatus is advanced along one row of a plurality of substantially parallel rows of tomato plants, said frame supporting means being a pair of skids straddling the plants in said one row;
c. knife means mounted on the forward end of said frame and projecting forwardly for cutting the plants in said one row ahead of said apparatus;
d. fore and aft conveyor means mounted on said frame for transporting the cut plants rearwardly toward the after end of said frame, said conveyor means including,
1. a main fore and aft power driven endless chain conveyor having an upper run mounted for movement from a forward location adjacent said knife means to receive the plants cut thereby rearwardly and upwardly toward said after end of said frame, and
2. a secondary fore and aft endless chain conveyor having a lower run movable in a rearward and upward direction and spaced above said upper run of said main conveyor a distance such as to engage the subjacent plants cut by said knife means and carried rearwardly and upwardly by said upper run of said main conveyor;
and,
e. elongated transverse conveyor means removably connected at one end to said after end of said frame and extending laterally to another one of said plurality of rows for transferring the cut plants from said one row toward said other row, said transverse conveyor means including,
1. a power driven endless belt, and
2. a supporting dirigible wheel mounted adjacent the other end of said transverse conveyor means, said dirigible wheel being mounted for movement along a path separating an adjacent pair of said plurality of rows as said apparatus is advanced along said one row,
said transverse conveyor means being of a predetermined length such that as the cut plants from said one row are discharged at said other end of said transverse conveyor means the cut plants from said one row are united with the plants in said other row and in which the united plants in said other row are capable of being harvested by a mechanical harvester.
