Abstract
Official abstract text for this publication.
A mini-hopper for an agricultural row unit that has a fill tube supplying material to a hopper. A backflow preventer is disposed in the fill tube or in a line to the inlet to prevent flow of material from the mini-hopper through the fill tube when the mini-hopper is in a transport position.
First claim
Opening claim text (preview).
What is claimed is: 1. An agricultural planter comprising: a toolbar; a main hopper; and a plurality of row units connected to the toolbar, wherein each row unit comprises: a frame configured to rotate between an operating position and a transport position; a hopper supported by the frame; an inlet connected to the hopper; and a fill tube supplying the hopper via the inlet, the fill tube comprising a first section and a second section connected by a backflow preventer, the backflow preventer comprising a flexible tubular member configured to be in an unflexed state when the frame is in the operating position and in a flexed state when the frame is in the transport position, wherein the backflow preventer permits flow from the fill tube into the inlet when the flexible tubular member is in the unflexed state and prevents flow from the inlet to the fill tube when the flexible tubular member is in the flexed state, wherein the hopper on each row unit is connected via a supply line to the main hopper. 2. The planter of claim 1 , wherein the toolbar has a plurality of sections including at least two wings. 3. The planter of claim 2 , wherein the wings are configured to be folded to reduce a width of the planter.
