Air seeder/fertilizer apparatus having metering means and distribution manifold with selectively openable ports
First Claim
1. An agricultural implement for injecting at least one type of particulate material namely seed, fertilizer, or inoculant into soil, adapted to travel over an area of ground having both seeded portions which have had said particulate material injected therein and unseeded portions of ground which have not had said particulate material injected therein, and to inject said particulate material only into said unseeded portions of ground, comprising;
- a plurality of soil-engaging members and associated raising means, each raising means when actuated adapted to raise an associated soil-engaging member from a lowered operating position where said soil-engaging member engages soil to a raised inoperative position;
a plurality of material-dispensing means for receiving said particulate material and dispensing said particulate material into furrows created by said soil-engaging members;
a metering means for dispensing said particulate material at a metered rate;
a distribution manifold, having;
(i) an inlet port for receiving metered particulate material from said metering means;
(ii) a plurality of outlet ports, and(iii) valve means on each of said plurality of outlet ports to permit selected opening and closing of said plurality of outlet ports;
said metering means dispensing said particulate material to said distribution manifold at said metered rate proportional to a rate of travel of said implement over the ground.

Abstract
A seeding apparatus having a distribution manifold with selectively openable outlet ports thereon, to permit or stop delivery of seed or fertilizer to soil A meter device, responsive to both the number of selected open ports and the speed of the apparatus over the ground, is provided to regulate supply of seed/fertilizer to a distribution manifold. The distribution manifold has a plurality of outlet ports spaced about a periphery of such manifold, each outlet port having a valve to allow opening and closing of individual outlet ports. Soil engaging members on such apparatus are individually raisable from an lowered operative position to a raised inoperative position, and when moved to such inoperative position, valve associated with an outlet port for providing seed and/or fertilizer to such soil engaging member is closed to prevent supply to the associated soil engaging member.

9. An agricultural implement for injecting particulate material namely seed, fertilizer, or inoculant into soil, towable behind a vehicle such as a tractor, comprising:
-
a wheeled cart having at least one containment bin mounted thereon for containing said particulate material; a tool bar adapted to be operatively coupled to said wheeled cart, comprising a plurality of elongate mounting arms mounted thereto, each mounting arm adapted to be moved from a raised transport position to a lowered operating position, soil engaging means mounted on each of said mounting arms, adapted to engage soil when each of said mounting arms is in said lowered operating position; material-dispensing means on each of said mounting arms, proximate said soil engaging means, for dispensing said particulate material into the soil; a distribution manifold, having; (i) an inlet port for centrally receiving therein metered particulate material; (ii) a plurality of outlet ports, arranged about a circular periphery of said manifold., each in fluid communication with a corresponding one or more of said material-dispensing means; and (iii) valve means on each of said plurality of outlet ports to permit selected opening and closing of said plurality of outlet ports; metering means adapted to distribute said particulate material to said inlet port of said distribution manifold at a metered rate, said metered rate proportional to both a rate of travel of said implement over the ground and a number of outlet ports on said distribution manifold which have been selectively opened. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An agricultural implement for injecting particulate material namely seed, fertilizer, or inoculant into soil, towable behind a vehicle such as a tractor, comprising:
-
a central frame; at least one containment bin mounted on such central frame, for containing said particulate material; a plurality of elongate mounting arms mounted to said central frame, each mounting arm adapted to be moved from a raised transport position to a lowered operating position, soil engaging means mounted on each of said mounting arms, adapted to engage soil when each of said mounting arms is in said lowered operating position; material-dispensing means on each of said mounting arms, proximate said soil engaging means, for dispensing said particulate material into the soil; a distribution manifold, having; (i) an inlet port for receiving metered particulate material; (ii) a plurality of outlet ports, each in fluid communication with at least one material-dispensing means on said soil-engaging members; and (iii) valve means on each of said plurality of outlet ports to permit selected opening and closing of said plurality of outlet ports; metering means adapted to distribute said particulate material to said inlet port of said distribution manifold at a metered rate, said metered rate proportional to both a rate of travel of said implement over the ground and a number of outlet ports on said distribution manifold which have been selectively opened. - View Dependent Claims (18, 19)
