Abstract:
A sub-surface seeding, fertilizing and watering device comprising:an opening blade,said opening blade having first and second sides extending between a leading edge and all aft edge,said first and second sides generally symmetrical to each other on either side of a first plane, said first plane generally bisecting said opening blade, said leading edge and said aft edge lying generally in said first plane,said opening blade mountable to a material feeder so as to be generally vertically disposed when mounted thereon for partial submerging into soil to a first submerged depth during forward translation advancing said leading edge through the soil,said opening blade having an upper surface and a lower surface extending between upper and lower edges respectively of said first and second sides,first and second wings mounted to said first and second sides respectively in generally oppositely disposed relation so as to be cantilevered outwardly therefrom, said first and second wings extending between first and second forward wing edges and first and second aft-opening wing apertures in said first and second wings respectively, said first and second wings mounted to said first and second sides at, respectively, first and second distances from said lower surface measured generally parallel to said first plane,said opening blade having therethrough, and generally lying in said first plane, first and second conduits,said first and second conduits extending from, and cooperating with, at uppermost ends thereof, first and second infeed ports in said upper surface,said first and second conduits cooperating with, at lowermost ends thereof, first and second wing ducts extending aft through said first and second wings respectively between said lowermost ends of said first and second conduits and said first and second aft opening wing apertures,said first and second conduits and corresponding said first and second wing ducts thereby in material flow communication between said first and second infeed ports and corresponding said first and second aft opening wing apertures for seed fertilizer or fluid flow, as fed from said material feeder, therethrough during said forward translation,wherein said first and second distances are less than said first submerged depth so that said first and second wings are submerged in the soil during said forward translation,wherein said first and second sides have upper portions generally located between said first and second wings and said upper surface, and lower portions generally located between said first and second wings and said lower surface,and wherein said lower portions collectively from a waisted shoe sole shape so that a forward width dimension of a forward flared portion of said opening blade and an aft width dimension of an aft flared portion of said opening blade, said forward and aft width dimensions extending between said lower portions of said first and second sides, are greater than an intermediate width dimension of a curvaceously waisted portion longitudinally extending contiguously between and smoothly flaring into said forward and aft flared portions.
