Air drill apparatus
First Claim
1. Air drill apparatus for towing behind a tractor and for placing particulate material in the ground, comprising:
- wheeled implement means adapted to be towed behind the tractor, said implement means including at least one transversely extending implement mounting bar;
at least one air drill assembly mounted to said implement mounting bar; and
container means for the particulate material to be placed in the ground, said container means including means for creating a positive air pressure to drive particulate material therefrom to said air drill assembly;
said air drill assembly comprising;
an elongated arm pivotally connected to said mounting bar;
a single thin, circumferentially sharp disc wheel rotatably mounted to said arm at a slight angle to the vertical and at a slight angle to the direction of travel for cutting a narrow furrow in the ground;
seed boot means connected to said container means and mounted to said arm adjacent said disc wheel and the ground for depositing particulate material in said furrow;
seed lock wheel means mounted to said arm adjacent and behind said disc wheel for pushing deposited seed or other particulate material deeper into said furrow; and
a single adjustable depth control wheel for controlling the depth of furrow cut by said disc wheel, said depth control wheel means being rotatably mounted to one end of a journal member the other end of which is rotatably mounted to said arm, said journal member including, extending upwardly therefrom, an arcuate portion having a series of equally spaced apart notches therein, said arm carrying a housing with at least one reciprocable latch member therein, said latch member being engageable with a selected one of said notches to adjust the position of said depth control wheel relative to said disc wheel.

Abstract
Air drill apparatus for towing behind a tractor and for placing seed or other particulate material in the ground includes wheeled implement mounting bars adapted to be towed behind the tractor, a plurality of air drill assemblies mounted to the implement mounting bars, and a wheeled towed container for the seed or other particulate material to be placed in the ground, the container including a pump for creating a positive air pressure to drive seed or other particulate material therefrom to the air drill assemblies. Each air drill assembly includes an arm pivotally connected to the mounting bar; a thin, circumferentially sharp disc wheel rotatably mounted to the arm at slight angles to the vertical and the direction of travel for cutting a narrow furrow in the ground; a seed boot connected to the container and mounted to the arm adjacent the disc wheel and the ground for depositing seed or other particulate material in the furrow; a seed lock wheel mounted to the arm adjacent and behind the disc wheel for pushing deposited seed or other particulate material deeper into the furrow; and an adjustable depth control wheel mounted to the arm for controlling the depth of furrow cut by the disc wheel.

12. Air drill apparatus for towing behind a tractor and for placing particulate material in the ground, comprising:
-
leading and trailing wheeled implement mounting bars adapted to be towed behind the tractor; a plurality of leading air drill assemblies mounted to said leading implement mounting bar; a plurality of trailing air drill assemblies mounted to said trailing implement mounting bar; and container means for the particulate material to be placed in the ground, said container means including means for creating a positive air pressure to drive particulate material therefrom to said air drill assemblies; each said air drill assembly comprising; an L-shaped mounting bracket having a horizontal leg thereof secured to one of the implement mounting bars and a vertical leg thereof extending upwardly in front of the one implement mounting bar; a mounting arm pivotally connected to said mounting bracket; tension spring means connected between the front end of said mounting arm and the upper end of said vertical leg of said bracket; a single thin, circumferentially sharp disc wheel rotatably mounted to said mounting arm at a slight angle to the vertical and at a slight angle to the direction of travel of said apparatus for cutting a narrow furrow in the ground; a hollow tube member mounted to said mounting arm, an upper end thereof being connected to said container means and the lower end thereof carrying a seed boot positioned closely adjacent said disc wheel and the ground for depositing particulate material in said furrow; a seed lock wheel mounted to said mounting arm adjacent and behind said single disc wheel for pushing deposited particulate material deeper into said furrow; and a single adjustable depth control wheel for controlling the depth of furrow cut by said single disc wheel, said depth control wheel being rotatably mounted to one end of a journal member the other end of which is rotatably mounted to said arm, said journal member including, extending upwardly therefrom, an arcuate portion having a series of equally spaced apart notches therein, said arm carrying a housing with at least one reciprocable latch member therein, said latch member being engageable with a selected one of said notches to adjust the position of said depth control wheel relative to said single disc wheel. - View Dependent Claims (13, 14, 15, 16, 17)
