Agricultural dry chemical tube and delivery system
First Claim
Patent Images
1. A chemical delivery system comprising:
- a ground working implement frame coupled to an opener-closer system;
the opener-closer system having a cutting-edge that creates a furrow in a soil;
a tube mounted to the opener-closer system following the cutting-edge of the opener-closer system and arranged rearwardly and proximate a tail member of a boot or scraper;
the tube having an inlet with a circular cross section of a uniform radius;
the tube having an outlet with an oval cross section that is positioned behind a dispensing opening of a liquid chemical tube arranged forward of the tail member of the boot or scraper relative to a direction of travel;
between the inlet and the outlet, a cross section of the tube transitions from circular to oval, wherein a diameter of the cross section of the outlet is smaller in size than a rear edge width of the tail member; and
the tube positioned in the opener-closer system to dispense chemicals into the soil.

Abstract
A dry chemical delivery tube and its surrounding nutrient applicator system are located in a narrow space in a soil working implement in an agricultural setting. Between an inlet end and an outlet end, the chemical delivery tube transitions from a circular cross section to an oval cross section. In one embodiment, the soil working implement includes soil opening/closing disks and liquid or gaseous delivery tubes that closely surround the chemical delivery tube.
