Fertilizer spike injection tool

A tool for injecting solid fertilizer spikes into soil for tree and plant root nutrition utilizing elongated brackets, comprising:

• an elongated hollow handle shaft tube having an upper end and a lower end;
• a handle or end cap formed around the outer surface of the upper end of said elongated hollow handle shaft tube or alternatively an end plug inserted into the upper end of said elongated hollow handle shaft tube;
• two identical diametrically opposing elongated brackets having an upper end connected to the lower end of said handle shaft tube such that the lower end of said brackets extend thereupon a distance to form an open-ended elongated hexagonal shaped fertilizer spike chamber;
• a flat base plate having an elongated hexagonal shaped aperture located in the center for loading therethrough a solid fertilizer spike is fixed to the lower end of said elongated brackets;
• said elongated hexagonal shaped aperture in said base plate is fixed directly over and inline with the lower end of said open-ended elongated hexagonal shaped fertilizer spike chamber formed by said two identical diametrically opposing elongated brackets;
• a foot bar being adapted to be longitudinally moveable between said two diametrically opposing elongated brackets from the uppermost position at the bottom of the lower end of said handle shaft tube, for the purpose of loading of the fertilizer spike, to the lowest position on top of said base plate at which point the fertilizer spike has been fully injected into the soil simultaneously with being fully ejected from said fertilizer spike chamber;
• an elongated rigid injector tube, having an upper end and a lower end disposed and longitudinally reciprocally moveable within said elongated handle shaft tube and said elongated brackets wherein the lower end of said elongated rigid injector tube extends perpendicularly through and beyond an accommodating aperture in said foot bar where it is fixed thereto dividing said foot bar such that a foot ledge extends equally on each side of said injector tube so as to provide a platform against which a person exerts force with both feet simultaneously, at the lower end terminates with a force-fitted plug or end cap to engage the top contact surface of a fertilizer spike;
• a ridged rod passes perpendicularly through compliant holes at the lower end of said injector tube and is fixed thereto such that equal lengths extend outwards adjacent to the inside corners of said brackets such that said rod facilitates concentric longitudinal reciprocal movement of said integrated foot bar and said injector tube;
• said ridged rod alternatively is a formed spacer around the peripheral edge of the lower end of said injector tube to facilitate concentric longitudinal reciprocal movement of said integrated foot bar and said injector tube;
• said ridged rod alternatively is adapted with a spacer to fit between said two diametrically opposing elongated brackets and said foot bar to facilitate concentric longitudinal reciprocal movement of said foot bar;
• a spring, having an upper end secured to the side wall of said handle shaft tube and a lower end of size and shape to engage said rigid rod when said foot bar is raised by a person upward towards said handle or end cap of said handle shaft tube, causing said injector tube and said foot bar to be held in place until released by downward force by a person on the top of said foot bar;
• said spring alternatively having an upper end secured to the side wall of the upper end of said injector tube and a lower end of size and shape to engage with a pin, rod or bolt fixed to said handle shaft tube when said foot is raised by a person upward towards said handle or end cap of said handle shaft tube causing said injector tube and said foot bar to be held in place until released by downward force by a person on the top of said foot bar;
• a fertilizer spike retention mechanism, fixed onto said base plate within the open sides spaces formed by said two diametrically opposing elongated brackets such that the underside foot bar flanges of said foot bar are longitudinally moveable over said fertilizer spike retention mechanism down to the topside of said base plate, by design and mechanical nature receives and sufficiently holds a fertilizer spike within said fertilizer spike chamber until ejected by said injector tube;
• said fertilizer spike retention mechanism alternatively incorporated into said identical diametrically opposing elongated bracket(s);
• said tool being fully operable in an upright position wherein a fertilizer spike is left embedded in the ground and detached from said tool without the need to remove said tool from the ground in a manner where, with one process of downward movement of said foot bar, two functions occur simultaneously, namely;
• the full injection of the fertilizer spike into the soil concurrent with the full release of the fertilizer spike from said tool by the complete ejection of the fertilizer spike from said fertilizer spike load chamber and said fertilizer spike retention mechanism of said tool.
