ABSTRACT:
An apparatus for plucking tobacco leaves has a pair of supporting members. These members are positioned on either side of a row of tobacco plants and extend parallel to this row and can move along the row. Two front arms are pivotally connected at the upper end to the supporting members. Two rear arms are pivotally connected at the upper end to the supporting members. A leaf-plucking arm is pivotally connected at both ends to the lower ends of the front and rear arms connected to one of said supporting members, whereby the leaf-plucking arm, the front and rear arms and the supporting member form a parallel linkage. Another leaf-plucking arm is pivotally connected at both ends to the lower ends of the front and rear arms connected to the other support member, whereby this leaf-plucking arm, the front and rear arms and the supporting member form another parallel linkage. The leaf-plucking arms extend parallel to each other and are spaced apart, forming a gap wide enough to allow the passage of a tobacco stalk and to provide a gap between the stalk and either leaf-plucking arm. Further, wheels are rotatably attached to each of said leaf-plucking arms and arranged at regular intervals in the lengthwise direction of the leaf-plucking arm. Each wheel has spokes extending into the gap between said leaf-plucking arms. A crank mechanism is provided to move the rear arms back and forth.
