Pneumatic system and method for a folding toolbar and seed planter assembly

摘要

A pneumatic manifold is provided for a folding toolbar for use with seed planters having pneumatic seed metering devices. The manifold is formed within the tubular center section and opposite folding wings of the toolbar. A flexible coupler is provided at each wing hinge juncture to provide air flow through the toolbar wings and the center section, while allowing the toolbar to fold and unfold between the transport and field positions.

主权项

1. In combination, an improved folding toolbar and a plurality of seed planters, the toolbar having:
a frame including a center tube and opposite left and right wing tubes pivotally attached to the center tube for movement between a folded transport position and an unfolded field position;
the improvement comprising:left and right flexible bellows each having opposite ends so as to extend between the center tube and the left and right wing tubes, respectively, such that that left and right wing tubes move between the transport and field positions without decoupling the bellows from the left and right wing tubes and the center tube;a plurality of hoses each extending between one of the wing tubes and one of the seed planters to provide air flow between the one wing tube and the seed planter; andan air source on the frame to move air through the plurality of hoses, the left and right wing tubes, the left and right bellows, and the center tube to dispense seeds from the plurality of seed planters.
