Patent ID: 8707878

Claim:
A system for forming holes in ground and for controlled delivery of particles into the holes, comprising: a first chamber configured to hold a liquid; a second chamber configured to hold the particles; a first pressure mechanism operable to maintain the liquid in the first chamber at a first pressure level; a first pump operable to transfer the particles from the second chamber to a third chamber; a first valve activated during a first time period to regulate the delivery of the liquid into the third chamber through a first opening; a second opening configured to direct jets of liquid from the third chamber during the first time period to form holes in the ground; a second valve activated during a second time period to regulate the first pump to transfer the particles to the third chamber wherein the first valve is closed during the second time period preventing the liquid from entering the third chamber while the particles are transferred to the third chamber; and the first valve activated during a third time period to regulate the delivery of the liquid to the third chamber through the first opening causing jets of the particles to be directed through the second opening into the holes.
