Benefits of technology

The present invention is designed to operate in different soil types and heavy residue. It uses two conical shaped wavy blades to provide openings side-by-side. The front coulter creates a slot and moves soil laterally while the second rear blade moves soil laterally in the opposite direction. This allows liquid to fill in the voids between the two paths. One conical wavy blade system can also be used to reduce the amount of liquid used. The slurry delivery tube is mounted to the rear coulter hub support arm. The front coulter can be operated at the same depth as the rear coulter or shallower if desired. The coulter application has limitations regarding gallons per acre depending on soil moisture. The shank that the rear coulter and the closer blades are mounted to can be removed to install a curved shank for sweeps. The high gallon per acre sweeps can accommodate a 20,000 gallon application rate, providing a wide range of application.

Problems solved by technology

This coulter application has limitations regarding gallons per acre.

Embodiment Construction

[0020]Referring to FIG. 1, there is shown a right side elevation view of the overall rotary applicator unit for spreading dry fertilizer or livestock waste in the form of a slurry. Reference number 1 generally designates a spring reset mechanism for a single row unit of a slurry applicator. As is known, a number of such applicator units are mounted on a wagon with a tool bar 27 drawn by a tractor (not shown). The applicator units are mounted in side-by-side relation and in a spaced manner. The tool bar 27, or frame, may have its own support wheels, or may be mounted to a wagon carrying the slurry. In any case, tool bar 27 trails a slurry wagon, or container, (also not shown for convenience) for a large amount of slurry fertilizer which is to be applied to a field. A coiled spring 73 is compressed (i.e. preloaded) and pivotally connected to a main shank 5 by bolt 55. When a rock or other obstruction is encountered by the rear conical coulter blade 21, the main shank 5, the rear conic...

Abstract

An applicator for applying dry fertilizer or livestock waste in the form of a slurry beneath the soil surface with minimum soil displacement includes a leading spring-cushioned, conical-shaped, wavy coulter angularly offset from the direction of travel which displaces soil laterally in forming a furrow adapted to receive fertilizer. The coulter is trailed by a single, or a pair of, rotary blade(s) which fill the furrow, covering the deposited fertilizer. A second embodiment includes a second wavy coulter disposed between the leading coulter and the trailing rotary blades for directing soil in a laterally opposed direction from the soil displaced by the leading coulter in forming a wider furrow. The single conical coulter and dual conical coulter embodiments are easily interchangeable in the applicator, and are easily removed and replaced with a curved shank and sweep assembly to convert to sweep fertilizer application.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 U.S.C. §119 from prior provisional application No. 61 / 609,037 which was filed on Mar. 9, 2012, herein incorporated by reference.FIELD OF THE INVENTION[0002]The present invention relates to agricultural fertilizer applicators; and more particularly, it relates to apparatus for subsoil application of dry fertilizer or livestock waste in the form of slurry (that is, a freely flowable mixture of liquids and solids).BACKGROUND OF THE INVENTION[0003]Historically, livestock waste, particularly in solid form, has been spread on the surface of the soil by a manure spreader using a flail to fling the material to the rear. A more modern side-discharge spreader also deposits the material on the surface of the soil.[0004]The advent of confinement systems for animals which include pits below the confinement area produces a large amount of animal waste in a slurry form which must be handled and disposed of Typica...
