Abstract
A finger wheel adapted to follow behind and/or beside a furrow opener at varying angles to the vertical and to the direction of travel. The finger wheel is useful for covering a furrow with loose soil to retain gaseous material such as anhydrous ammonia in the soil. The finger wheel is also useful for removing dry soil from the top of a seed furrow to reduce the effective depth of seeding and improve emergence. Also provided are a gaseous material injector and seeding apparatus using a known double inclined disc in combination with the finger wheel.
Claims18
An apparatus for injecting gaseous material into soil, said apparatus adapted to be mounted on a frame adapted to travel along the ground, said apparatus comprising:
- a rotating furrow opening disc having an axis of rotation firstly inclined from a position perpendicular to the line of travel, such that a leading side of said disc moves soil to the leading side as it travels through the soil making a furrow, said axis of rotation secondly inclined from the horizontal such that said leading side is above a trailing side of said disc;
- means to introduce a gaseous material at a point adjacent to the bottom of the furrow formed by said disc;
- a wheel having a plurality of fingers radially extending from the axis of rotation of said wheel, said wheel adapted to roll along the ground on a path adjacent to the leading edge of said furrow;
- wherein the axis of rotation of said wheel is firstly inclined from a position perpendicular to the line of travel opposite the first inclination of said disc, and secondly inclined from the horizontal.
