Furrow opener for seeder
First Claim
1. An auxiliary furrow forming plate for an agricultural granular material applicator furrow opening shank include means for mounting the plate on a shank of a granular material applicator at a level adjacent the bottom of a main furrow formed by such shank when working, a major portion of said plate trailing such shank, said plate being below ground level when a shank on which the plate is mounted is at a working depth, said plate having wedge shaped side portions along opposite sides thereof, each wedge shaped side portion having a pair of wedge surfaces that converge downwardly and define edges where the converging surfaces meet that at least have portions that are laterally wider than a furrow opened by a shank mounting the plate, the defined edges being spaced downwardly from the main portion of the plate in rearward direction relative to direction of movement of the plate when working, one of the converging surfaces of each wedged shaped side portions facing a surface on the other wedge shaped side portion at a position below the plate, the first and second surfaces of each wedge shaped side portion diverging in rearward direction so the wedge shaped side portion are wider at their trailing ends, the wedge shaped side portions forming auxiliary furrows laterally of a shank on which the sealer plate is mounted at location below the ground, by packing the earth as the plate moves forwardly to provide a pair of firm beds at the rear of each of the wedge shaped side portions and into which granular material may be deposited.

Abstract
A furrow opener shank for use with seeders has seed outlets and fertilizer outlets at the lower end thereof, and includes a sealer plate which will permit the depositing of anhydrous ammonia or liquid fertilizer in a deep furrow and which positively seals the furrow prior to depositing the seeds in the furrow. The sealer plate has wedges that form a pair of grooves or small furrows spaced laterally of the center line of the furrow to provide pockets for the seeds being deposited. The shank has dual outlets for seed at the lower end so that seed is deposited in each of the furrows that are being formed by the sealer plate to keep the seed separated from the fertilizer to insure good germination and rapid growth as well as insuring placement of the seed in regions that are most likely to have moist soil.

1. An auxiliary furrow forming plate for an agricultural granular material applicator furrow opening shank include means for mounting the plate on a shank of a granular material applicator at a level adjacent the bottom of a main furrow formed by such shank when working, a major portion of said plate trailing such shank, said plate being below ground level when a shank on which the plate is mounted is at a working depth, said plate having wedge shaped side portions along opposite sides thereof, each wedge shaped side portion having a pair of wedge surfaces that converge downwardly and define edges where the converging surfaces meet that at least have portions that are laterally wider than a furrow opened by a shank mounting the plate, the defined edges being spaced downwardly from the main portion of the plate in rearward direction relative to direction of movement of the plate when working, one of the converging surfaces of each wedged shaped side portions facing a surface on the other wedge shaped side portion at a position below the plate, the first and second surfaces of each wedge shaped side portion diverging in rearward direction so the wedge shaped side portion are wider at their trailing ends, the wedge shaped side portions forming auxiliary furrows laterally of a shank on which the sealer plate is mounted at location below the ground, by packing the earth as the plate moves forwardly to provide a pair of firm beds at the rear of each of the wedge shaped side portions and into which granular material may be deposited.
- 2. An auxiliary earth working plate including means for mounting it on a shank of a seeder above the bottom of a main furrow formed by such shank when working, a major portion of said plate trailing such shank, means for positioning said plate below ground level when a shank on which the plate is mounted is at a working depth, said plate having wedge shaped side portions along opposite sides thereof, each wedge shaped side portion having a pair of wedge surfaces that converge downwardly in use and define edges where the converging surfaces meet that are to the exterior of a furrow opened by a shank mounting the plate, the defined edges also tapering downwardly in rearward direction relative to direction of movement of the plate when working, one of the converging surfaces of each wedge shaped side portion facing a surface on the other wedge shaped side portion and the facing surfaces tapering toward each other in rearward direction, the wedge shaped side portions forming small auxiliary furrows laterally of a shank on which the plate is mounted, at location below the ground, by packing the earth to provide a pair of firm seed beds at the rear of each of the wedge shaped side portions into which seed may be deposited.
- 6. An auxiliary furrow forming plate for mounting onto the shank of a seeder, which shank opens a furrow having a first depth, said furrow forming plate including means for mounting the furrow forming plate on such shank for movement below ground level when a furrow is opened by such shank to the first depth, said plate having a leading end and a trailing end in use, said trailing end being wider than the leading end and said plate having side edges extending from the leading end to the trailing end, said plate further having a central downwardly facing substantially flat surface portion and a pair of depending auxiliary furrow forming portions adjacent the opposite lateral side edges thereof positioned on opposite sides of the flat surface portion, with the flat surface portion between said furrow forming portions, said furrow forming portions each having first and second surfaces that taper toward each other from a maximum spacing between the first and second surfaces of each furrow forming portion at the upper edges thereof to a furrow forming lower edge, the lower edges of said furrow forming portions being wider than and extending outside a furrow formed by a shank mounting the plate, and which lower edges further taper downwardly in direction toward the trailing end of the plate, and the first surface of each furrow forming portion facing the first surface of the other furrow forming portion, the upper edges of the first surfaces of the furrow forming portion extending along the central flat surface portion and tapering toward each other in rearward direction, the furrow forming portions thereby packing dirt to form a pair of spaced apart small auxiliary furrows each being a packed preformed bed laterally outwardly of a shank mounting the sealer plate for depositing granular materials thereinto.
