Patent ID: 7775168

Claim:
An apparatus for injecting viscous fertilizer below the surface of the soil, comprising: (a) a container box that is upwardly open; wherein said container box has at least a first, second, and third side wall, said third side wall having an outlet hole through which said viscous fertilizer may pass outside said container box; (b) means for conveying said viscous fertilizer from said container box, comprising (1) a push blade disposed so as to prevent said viscous fertilizer from escaping said apparatus from the side of said container box opposite said third side wall; and (2) a means for moving said push blade at least partially within said container box toward said third side wall to effect exit of contained viscous fertilizer through said outlet hole; (c) pumping means for receiving said viscous fertilizer from said containing means via said conveying means and for displacing said viscous fertilizer under pressure; (d) proportioning means for receiving said viscous fertilizer from said pumping means under pressure and distributing said viscous fertilizer into at least one outlet port under pressure; (e) delivery means for moving said viscous fertilizer from said outlet ports under pressure; and (f) injection means for receiving said viscous fertilizer from said delivery means and injecting said viscous fertilizer below the surface of the soil as said injection means is moved in a forward direction; wherein said third side wall additionally comprises one or more surfaces obliquely facing said push blade so as in operation to direct said viscous fertilizer toward said outlet hole.
