US Patent:

6668738, Dec 30, 2003

Filed:

Mar 21, 2002

Appl. No.:

10/101877

Inventors:

Laurence K. Lee - Darien IL
Guntis Ozers - Woodridge IL

Assignee:

Case, LLC - Racine WI

International Classification:

A01C 704

US Classification:

111175, 111174

Abstract:

A particulate distribution system for transporting seed or other particulate from a source into a plurality of metering bins, the system including a forced air source, a converter for splitting air form the source into separate flows in converter outlet lines, venturis for receiving the air flows and entraining particulate from a main hopper therein and a manifold delivery system that directs the entrained particulates to mini-hoppers and that opens at an outlet end back into the main hopper.

Assignee:

Case, LLC - Racine WI

International Classification:

A01C 718

US Classification:

111200, 111925, 220562, 220475

Abstract:

A method and apparatus for use with a planting assembly including a first mounting member having first and second horizontally separated ends, the apparatus comprising first and second rigid support members that extend in the same direction from and substantially perpendicular to the first and second ends of the mounting member and that form first and second support surfaces, respectively, a hopper including first and second lower wall members that together define an upwardly facing cavity and form first and second downward and oppositely facing external surfaces, respectively, the external surfaces sloping downward toward a hopper opening along first and second trajectories, respectively, the hopper positioned on the support members such that the first and second external surfaces are received on the first and second support surfaces, respectively, the first external surface forming a first hopper coupler having an engaging length dimension along the first trajectory and a first locking member having a first locking coupler formed to be received by the first hopper coupler at various juxtapositions along the engaging length, the first locking member further including a first engager integrally formed with the first locking coupler and operable to lock the first locking coupler to the first support member.

Appl. No.:

10/101873

Inventors:

Laurence K. Lee - Darien IL
Guntis Ozers - Woodridge IL

Assignee:

Case, LLC - Racine WI

International Classification:

A01C 718

US Classification:

111 63, 111200, 111925, 111175, 221174, 221278, 222630

Abstract:

A particulate distribution apparatus for receiving seed or other particulate from a pneumatic source and temporarily storing the seed for subsequent use by a metering device where the particulate is characterized by a particulate size, the apparatus comprising a housing including walls that form a cavity, a hopper inlet linkable to the duct outlet and a hopper outlet linkable to the metering device inlet, at least one of the housing walls forming vent apertures that are generally smaller than the particulate size.

Assignee:

Case Corporation - Racine WI

International Classification:

A01C 2300

US Classification:

111174, 111118, 111925, 220562, 220475

Abstract:

An apparatus for use with a planting assembly including a mounting member and comprising a hopper including first and second wall members that form first and second hopper external surfaces wherein first and second forces applied perpendicular to the first and second surfaces include at least components along first and second opposing trajectories, respectively, a first elongated bearing member rigidly linked to the mounting member and forming a first bearing surface that applies a first applied force to the first hopper surface wherein the first applied force includes at least a first compressing component along the first trajectory, a second elongated bearing member forming a second bearing surface and having a first end and a retainer linked to the first end of the second bearing member and rigidly linking the second bearing member to the mounting member in any of several different positions relative to the first bearing member so that the second bearing surface applies a second applied force to the second hopper surface wherein the second applied force includes at least a second compressing component along the second trajectory.

International Classification:

A01C001/00

US Classification:

111/200000

Abstract:

A particulate distribution system for transporting seed or other particulate from a source into a plurality of metering bins, the system including a manifold duct that begins and ends at the source and an air delivery system mounted to the duct to transport particulate there through and a plurality of particulate flow diverting structures that extend from the manifold into each metering bin, whereby each metering bin is filled in accordance with the flow of air available thereto.
