ABSTRACT:
A mechanism for adjusting the stalk-receiving gaps between stripper plates in a produce harvester. The mechanism is adapted for use in harvester where a number of pairs of stripper plates are utilized, and where a space is formed between adjacent pairs of stripper plates, and a stalk-receiving gap is formed between the stripper plates within each pair. The mechanism permits all stalk-receiving gaps in the harvester to be adjusted simultaneously and to the same degree. These gaps are adjusted from both sides allowing for optimum centering of the gap to engage the stalks. The mechanism comprises a reciprocating shaft disposed so as to move substantially perpendicular to the movement of the harvester. A number of rotating shafts are connected to the reciprocating shaft and these are disposed within the spaces between adjacent pairs of stripper plates. The rotating shafts are disposed substantially at right angles to the movement of the harvester. Each rotating shaft is connected to the stripper plates on either side of the space between the adjacent pairs of plates by linkage arms. As the reciprocating shaft is moved, the rotating shafts rotate or roll, causing the stripper plates on either side of the spaces between adjacent pairs to move towards or away from each other, depending on the direction of movement of the reciprocating shaft. This movement causes the stalk-receiving gaps to be increased or decreased in size.
