US 5,682,829 A · Apparatus for injecting liquid manure into the soil

Abstract

A combination of a wheel supported liquid manure tank having a rearward end and a liquid manure soil injection device secured to the rearward end. The injection device is mounted on the rearward end of the tank and is capable of being raised and lowered by hydraulic cylinders. A plurality of substantially parallel support arms extend rearwardly from the tank and have a disk rotatably supported intermediate the ends thereof. The disk is mounted at an oblique angle with respect to the forward line of travel of the tank, that is, the disk is inclined laterally from a vertical plane approximately 2 degrees and is skewed with respect to the line of travel approximately 5 degrees. The disk is adapted when engaging the soil to open a slit therein. A nozzle operatively connected to the tank has its lower end disposed immediately above the slit. A cleaning knife is secured to the nozzle adjacent the disk on one side thereof to engage the disk and remove particles of earth which might adhere to the disk. A rubber cleaning wheel with a lip thereon engages the opposite side of the disk for the same purpose. That wheel also extends rearwardly from the tank. A closure wheel is mounted on the rearward end of the support arm to rotate over the open slit to close the same.

Dependent claims

A liquid manure soil injection device, comprising,

an elongated support arm having forward and rearward ends,
attachment means on said forward end to secure said support arm to the rearward end of a liquid manure tank adapted to have a forward line of travel,
a hub on said support arm intermediate the forward and rearward ends thereof,
an earth cutting disk rotatably mounted on said hub, and having opposite side surfaces for movement through soil,
said earth cutting disk having an axis of rotation which forms both a lateral and vertical angle with respect to said line of travel as to be obliquely positioned when moved forwardly to open an elongated slit in the soil in which said disk is moving,
and a liquid outlet nozzle on the rearward end of said support arm and adapted for connection to said tank and being positioned rearwardly of said hub and adjacent said disk for delivery of liquid manure into the slit created in the soil by said disk.
