Method and system for high pressure liquid injection of turf seed
First Claim
1. A method for overseeding turf seed into turf grass comprising:
- mixing seed with a liquid to form a seed-liquid mixture;
placing the seed-liquid mixture in an accumulator;
raising the pressure within the accumulator to a predetermined level; and
fluidly coupling the seed-liquid mixture to a nozzle so as to cause the seed-liquid mixture to flow through the nozzle and into the turf grass.

Abstract
A turf care system and method uses simultaneously fired pulses of high-pressure liquid jets of the mixture shot toward the ground. The liquid is mixed with dry grass seed shortly before being delivered to a high-pressure liquid/seed pumping system, which uses an accumulator and sequencing valve to produce at regular repetitive intervals pulses of the liquid/seed mixture under high pressure. The pulses are delivered to an elongated hydraulic manifold having multiple nozzles pointed downwardly, which are spaced from one another and the ground by predetermined distances. The momentum of the high-pressure jet of liquid/seed mixture issuing from each nozzle cuts through overlying vegetation to deposit the seeds into the crown of the soil at predetermined desired depth. Spray patterns are determined by nozzle orifice shape, and are preferably selected to provide a shallow knife slit-like opening or trench in the crown of the turf.

11. The mechanism for injecting a seed-liquid mixture into a turf grass bearing medium having:
-
a nozzle;
an accumulator for storing the seed-liquid mixture under pressure coupled to the nozzle;
a pump for increasing the pressure of the seed-liquid mixture; and
a regulator for regulating the flow of the liquid-seed mixture from accumulator through the nozzle, wherein the nozzle is configured to inject the liquid-seed mixture through the turf grass. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
