Abstract

Liquid applications of materials such as herbicides usually are broadcast over the field and then incorporated by harrowing or the like. The present device utilizes a plurality of open based boxes having a rotary cultivator therein with a spray nozzle attached to a supply of liquid chemical under pressure thus restricting the application of the chemical to a band the width of the box and incorporating it at the same time. Rake teeth smooth out the soil behind each applicator and a seeding or planting machine may be hitched behind the incorporator followed by a packer so that the entire chemical treatment, incorporation thereof, planting and packing can be undertaken in one pass over the field.

Claims

1. An agricultural implement for seeding and incorporating chemical in bands spaced laterally of a working direction and movement of the implement, the implement including a frame, a plurality of seeder units mounted on the frame spaced laterally thereof, a plurality of liquid chemical incorporating assemblies each associated with and aligned forwardly relative to a respective one of the seeder units and each comprising an enclosed casing having an open base, means to convey liquid chemical to the casing, nozzle means arranged to spray said liquid chemical on the ground within the casing and soil breaking teeth mounted on an axle fixed to the casing for rotation about a substantially horizontal axis within the casing, the soil breaking teeth including a portion extending radially from said axle and a portion bent relative thereto so as to lie substantially parallel to the axle and radially spaced therefrom, a power source on the frame, flexible coupling means for coupling power from said power source to each of said casings for driving the teeth therein, toothed raking means pivotally mounted on a rear portion of said casing for pivotal movement about a horizontal axis transverse to said casing for smoothing the soil behind said incorporating assembly and means mounting the casing on the frame for floating movement relative to the ground with the open base exposed to the ground, said mounting means comprising strut means extending forwardly and upwardly from the casing to the frame, said strut means being coupled to the frame for pivotal movement thereto so as to allow upward floating movement of the casing relative to the ground, the direction of rotation of said teeth being arranged so as to drive the casing forwardly whereby a reaction from said upwardly and forwardly extending means provides a component of force downwardly on the casing to force said casing against the ground, and a pair of horizontal skids mounted on said casing at lower side edges thereof for running along the ground in contact therewith.

2. The invention according to claim 1 wherein the toothed raking means is formed on the lower edge of a rear plate of said casing, said rear plate inclining rearwardly and downwardly from said casing with at least the raking means being spaced rearwardly from the rear edges of side plates of said casing.

3. The invention according to claim 1 including means for adjusting the angle between the casing and said upwardly and forwardly directed support means.

4. The invention according to claim 1 wherein the height of the skids relative to the side walls of the casing is adjustable so as to adjust the height of the axle relative to the ground.
