Abstract
A seeding implement which includes a cylindrical container having a bottom with a centrally located opening therein. A metering plate is located beneath said container, preferably defining a plurality of different sized orifices that are locatable beneath and concentric to the bottom wall opening of the container. An elongated, adjustable seed metering rod is provided which includes a flattened tip that resides within said bottom wall opening, and eccentric thereto, and with the rod being mounted for oscillatory motion. Removable mounting of a plurality of seeding implements on a soil renovating implement is also disclosed and claimed.
Claims20
An improved agricultural seeder implement comprising:
- (a) a container for seed to be metered onto the ground, said container including a bottom wall that defines an opening therein;
- (b) metering means located adjacent said bottom wall of said container, said metering means defining at least one orifice therein, said orifice being smaller than said opening in said bottom wall and concentric with respect thereto, said opening and said orifice cooperating to define a dispensing outlet for seed from said container;
- and
- (c) positive feed means received in said bottom wall opening and along an axis eccentric to a central axis through said orifice in said metering means, said feed means being adapted for arcuate motion about its axis whereby during said arcuate motion of said feed means, seed are positively metered through said orifice.
An improved agricultural seeding implement comprising:
- (a) a support means, said support means being adapted for transport by a motive power source;
- (b) a plurality of seed metering units provided on said support means in spaced apart relation, said seed metering units comprising a seed container, said container including a bottom wall that defines an opening therein, a metering plate located beneath said container and defining at least one orifice therin, said orifice being smaller than said opening in said bottom wall and being locatable concentric thereto, said opening and said orifice cooperating to define a dispensing outlet for seed from said container, and seed metering means received in said bottom wall opening and eccentric to said orifice, said metering means being mounted for oscillating motion thereat;
- and
- (c) drive means associated with all of said metering means for imparting oscillatory motion thereto.
A renovator-seeder implement comprising:
- (a) a main frame,
- (b) means received on said frame for connecting said implement to a motive power source;
- (c) a plurality of elongated elements secured to said frame in spaced relation, said elongated elements having means secured to a lower end of same for penetrating the soil during renovation;
- and
- (d) a plurality of seeder implements secured to said main frame in spaced relation, one said seeder implement being provided adjacent and rearward of each elongated element, said seeder implements comprising a container for seed to be metered onto the ground, said container including a bottom wall which defines an opening therein, metering means located adjacent said bottom wall of said container, said metering means defining at least one orifice therein, said orifice being smaller than said opening in said bottom wall and concentric with respect thereto, said opening in said orifice cooperating to define a dispensing outlet for seed from said container, and positive feed means received in said bottom wall opening and along an axis eccentric to a central axis through said orifice in said metering means, said feed means being adapted for arcuate motion about its axis whereby during said arcuate motion of said feed means, seed are positively metered through said orifice, said positive feed means of said seeder implements being oscillated by a common drive means.
