Collapsible grain chute
View Patent ↗A generally conically-shaped collapsible grain chute removably affixed to the bulk seed distributor of an agricultural planter to provide an effective and efficient apparatus for emptying the bulk seed bin. The chute may include a cinch cord to selectively open and close the chute to control the flow of seed therethrough.
1. An agricultural seed planter, comprising:
a wheel-supported frame adapted for travel across a field and planting a plurality of rows of seeds;
a plurality of row planting units supported by said frame in a generally equally spaced manner transverse to the direction of travel;
each said row planting unit having a hopper associated therewith for feeding seed to the respective row planting unit;
at least one bulk seed storage bin supported on said frame, and having a size greater than that of each said hopper;
a distributor affixed to the bottom of said at least one bulk seed storage bin, said distributor being part of a seed distribution system that moves seeds from said bin to each said hopper such that a constant flow of seeds is maintained to said row planting units, wherein said box-like distributor has an open top in seed flow communication with said bin, and an opposing open bottom; and
a grain chute attached to said distributor, said chute comprised of a flexible truncated funnel-shaped body with a generally rectangular end attached to said distributor, enclosing said open bottom, and a spaced-apart smaller outlet, wherein said outlet is selectively changeable between open and closed conditions, and wherein said outlet has a cinch chord there around for selectively changing said outlet between open and closed conditions.
2. The planter of claim 1 , wherein:
said flexible truncated funnel-shaped body is comprised of canvas.
3. The planter of claim 1 , wherein:
said flexible truncated funnel-shaped body is comprised of nylon.
4. The planter of claim 1 , wherein:
said distributor has at least one pin protruding therefrom on each of two opposing sides adjacent said open bottom; and
said chute includes a metallic frame at least partially enclosing said generally rectangular end and having holes therethrough that may be aligned with said at least one pin to attach said chute to said distributor.
5. The planter of claim 4 , wherein:
said chute is comprised of flexible synthetic material; and
said truncated funnel-shaped body has a vertical axis extending therethrough and said outlet is offset therefrom.
6. The planter of claim 1 , wherein:
said distributor has at least one pin protruding therefrom on each of two opposing sides adjacent said open bottom; and
said chute includes a metallic frame member on two opposing sides of said rectangular end and having top opening with horizontal slots extending therethrough that are configured to receive at least one pin to attach said chute to said distributor.
7. The planter of claim 6 , wherein:
said distributor includes at least one over-the-center latch on each of said two opposing sides; and
each said metallic frame member includes a catch for engaging respective said over-the-center latches.
