Seed tank arrangement and planter
A seed tank arrangement is provided with improved access to seed tanks of an agricultural planter and the contents thereof, while simplifying the manufacturing of such tanks. The seed tank has a fill opening formed in the upper surface of the tank for loading and accessing seeds in the interior of the tank. Features of the tank are mirror images about a diagonal plane of the tank, which enables the same tank to be used for both the left and right sides of the planter. This is achieved by rotating the left tank 90 degrees with respect to the right tank. The design provides improved access to the interior of the tanks for filling and servicing the seed.
1. A left and right seed tank for a planter comprising:
said left and right seed tank supported on a frame;
each left and right seed tank has a shell defining an interior volume configured to receive seeds;
each left and right seed tank has a fill opening formed in an upper surface of the shell for loading seeds into the interior volume, the opening being positioned off-center of the upper surface and equidistant from two adjacent sides of the shell, along a generally vertical diagonal plane bisecting the shell,
a cover disposed over the each fill opening;
wherein each shell has side angled at approximately 45 degrees with respect to two adjacent sides and centered on the vertical diagonal plane, the angled side being configured to be disposed in a rear position and adjacent to a centerline of the planter when installed;
whereby the left and right seed tank are identical and orientated at right angles with respect to one another.
2. The seed tank of claim 1 , wherein each shell has four sides, and the fill opening is positioned equidistant from a rear side and a side configured to lie adjacent to a centerline of the planter when installed.
3. The seed tank of claim 1 , wherein each shell includes a bottom chute disposed symmetrically with respect to the vertical diagonal plane.
4. The seed tank of claim 3 , further comprising an inductor box coupled to the chute, the inductor box having openings for receiving a flow of air and for distributing seeds to row units, the openings being disposed symmetrically with respect to the vertical diagonal plane.
5. A left and right seed tank for a planter comprising:
each left and right seed tank has a shell defining an interior volume configured to receive seeds;
each left and right seed tank has a fill opening formed in an upper surface of the shell for loading seeds into the interior volume, the opening being positioned off-center of the upper surface;
wherein the shell and fill opening are laterally symmetrical about a vertical diagonal plane bisecting the seed tank;
a cover disposed over each fill opening;
wherein the shell has a side angled at approximately 45 degrees with respect to two adjacent sides and centered on the vertical diagonal plane, the angled side being configured to be disposed adjacent to a centerline of the planter when installed;
whereby the left and right seed tank are identical and orientated at right angles with respect to one another.
6. The seed tank of claim 5 , wherein each shell includes a bottom chute disposed symmetrically with respect to the vertical diagonal.
7. The seed tank of claim 6 , further comprising an inductor box coupled to the chute, the inductor box having openings for receiving a flow of air and for distributing seeds to row units, the openings being disposed symmetrically with respect to the vertical diagonal plane.
