Abstract

A shank is used for seeding apparatus and has two passageways for permitting metered seed, and metered fertilizer to be placed into the ground from the same shank. A covering sealer shoe or plate for covering the fertilizer prior to the time that seed is deposited is provided to insure that the seed will be separated from the fertilizer by soil. The shank further includes a kit of attachments to permit easily changing the type of fertilizer applied from liquid to granular fertilizer, and also for changing the location of the depositing of the fertilizer. A further conversion includes the ability to deposit seed and granular fertilizer in one path or furrow, and apply a deep band of liquid fertilizer at the same time below the seed and granular fertilizer.

Claims

1. A planting apparatus comprising:

a tubular shank member having a pair of passageways therethrough extending from an upper end to lower discharge ports in each of said passageways, the port from a first of said passageways opening at a lower level, when the shank is in working position than the port from the second of said passageways;

a furrow opening point mounted on the lower end of said shank member and preceding the passageways in the normal direction of travel of said shank member when in a working position;

the first passageway being immediately to the trailing side of said furrow opening point and its discharge port opening above the lower edge of the furrow opening point, and

a sealer plate mounted on said shank member in position above the discharge port from the first of said passageways, to the rear of said furrow opening point and said first passageway, and below the discharge port of said second passageway, said sealer plate extending laterally outwardly on both sides of said shank member and tapering outwardly from the shank in rearward direction to be substantially wider at the rear than at the front to form rear wing members, the wing members being bent downwardly at the rear portions of the sealer plate along bend lines that extend from the outer edges of the sealer plate inwardly toward the shank in rearward direction so the wing members converge in rearward direction so that when the shank member is in working position the sealer plate is below the surface of the ground and the wing members pack dirt into a furrow opened by said furrow opening point prior to the passage along the furrow of the discharge port of said second passageway.

2. The apparatus specified in claim 1 wherein said sealer plate wing members have a substantially straight edge at the trailing edge thereof, and wherein said trailing edge is immediately ahead of and below the discharge port from the second passageway.

3. A shank for a planter comprising:

an upright support housing;

a furrow opening point mounted at the lower end of said housing, said housing being adapted to be mounted to hold the furrow opening point below the level of the ground to open a furrow, when in a working position;

means for defining a pair of discharge passageways for material defined in said housing, a first of said passageways having a first discharge opening substantially directly behind the furrow opening point and adjacent to the lower portions of the furrow opening point, the second of said passageways having a second discharge opening positioned to the rear of and above the first discharge opening;

a seed bed compaction plate member mounted on said housing above the first discharge opening from the first passageway, and at a level below the second discharge opening from the second passageway, said plate member being positioned to the rear of the first passageway and ahead of the second passageway with respect to the direction of travel, the compaction plate member sloping downwardly to pack the dirt into the lower portion of the furrow, and below the second discharge opening to provide a firm seed bed;

and adaptor means for the top of said shank for effecting the connections opening to each of the passageways, said adaptor means comprising a removable, replaceable cover plate, said cover plate having means for coupling at least one passageway to a source of material to be deposited in a furrow, said cover plate having an elongated tube fixed thereto which extends within one of the passageways to a position below the level of the ground to permit carrying liquid fertilizer into the ground.

4. The apparatus specified in claim 3 wherein said plate member has a trailing edge that is substantially perpendicular to the direction of travel throughout the width of the plate member.

5. A shank for a planter comprising:

an upright support housing;

a furrow opening point mounted at the lower end of said housing, said housing being adapted to be mounted to hold the furrow opening point below the level of the ground to open a furrow, when in a working position;

means for defining a pair of discharge passageways for material defined in said housing, a first of said passageways having a first discharge opening substantially directly behind the furrow opening point and adjacent to the lower portions of the furrow opening point, the second of said passageways having a second discharge opening positioned to the rear of and above the first discharge opening;

a seed bed compaction plate member mounted on said housing above the first discharge opening from the first passageway, and at a level below the second discharge opening from the second passageway, said plate member being positioned to the rear of the first passageway and ahead of the second passageway with respect to the direction of travel, the plate member sloping downwardly to pack the dirt into the lower portion of the furrow, and below the second discharge opening to provide a firm seed bed;

said housing comprising a tubular housing divided into a pair of generally upright passageways forming the first and second passageways; and

support rim means surrounding the passageways at the upper end of said housing, said rim means being adapted to support a removable replaceable cover plate, said lower plate housing comprising a cover plate being removably connectable to said rim means, and connection means on said cover plate for attachment to at least two sources of different materials selectively permitting a desired material to be discharged into selected ones of said passageways.

6. The apparatus of claim 5 wherein said cover plate connection means includes an elongated tube mounted on the cover plate and having a connection end on an upper side of said cover plate when the cover plate is installed on said housing, and said elongated tube having a discharge end that opens through one passageway to a position below the ground level through one of said discharge openings, said elongated tube being adapted to carry liquid fertilizer to discharge liquid fertilizer below the level of the ground in the furrow formed by the furrow opening point.

7. The apparatus of claim 5 wherein said cover plate has an elongated tube for carrying liquid fertilizer mounted on the cover plate and of length to extend through a first of said passageways in the housing, and said cover plate connection means including a connection tube opening into a secoond of said passageways in the housing when the cover plate is attached to said rim means.

8. The apparatus of claim 5 wherein said cover plate has an elongated tube for carrying liquid fertilizer mounted on the cover plate and forming part of the connection means, said tube being of length to extend through one passageway in the housing and through the discharge opening of such one passageway to discharge below the level of the ground when the shank is in working position, and said connection means also including a pair of separate connection tubes mounted on the cover plate and opening to the second passageway in the housing when the cover plate is attached to said rim means.

9. The apparatus of claim 5 wherein said cover plate connection means comprises a pair of connection tubes opening to the same passageway in the housing, said cover plate blocking the opening to the other of the passageways when the cover plate is mounted on said rim means.
