Abstract
The present invention relates to a tool and method of using the same for pushing or pressing rods into the earth. A moveable pusher body is mounted on an elongated, slotted mast, and is provided with several pivotal pusher plates which are implemented one at a time so as to press a rod into the ground, in incremental fashion, under the force of a downward stroke from a prime mover. A coupling tool may also be provided so that several lengths of rods can be inserted into the ground.
Claims19
A method of inserting a rod into the earth using a tool having a hollow pusher body, a hollow elongated mast slidably received within said pusher body and provided with an elongated slot extended axially along said mast and a plurality of pivotally mounted pusher plates spaced along said pusher body, comprising the steps of:
- (i) loading an elongated rod into said mast;
- (ii) pivoting a first pusher plate through said slot of said mast to enable engagement of the pusher plate and an end of the rod;
- (iii) applying a downstroke from a prime mover to said pusher body enabling said first pusher plate to push the rod into the earth a first distance;
- (iv) retracting said pusher body so that the end of the rod is adjacent a second pusher plate;
- (v) pivoting said second pusher plate through said slot in said mast to enable engagement of said second pusher plate and the end of the rod;
- (vi) applying a second downward stroke from the prime mover to said pusher body enabling said second pusher plate to push the rod into the earth a second distance;
- (vii) retracting said pusher body so that the end of the rod is adjacent a third pusher plate;
- (viii) pivoting said third pusher plate through said slot in said mast to enable engagement of said third pusher plate and the end of the rod;
- and
- (ix) applying a downstroke from the prime mover to said pusher body enabling said third pusher plate to push the rod into the earth a third and final distance.
A tool for pushing a rod into the earth, said tool comprising:
- pusher body;
- an elongated, slotted hollow mast positioned within said pusher body and sized and configured so that said pusher body may slide along said mast, said mast being adapted to receive the rod to be pushed into the earth;
- at least one pusher plate connected with said pusher body;
- said pusher plate being pivotable inwardly of said elongated, slotted mast to engage the rod so that a downwardly directed force applied to said pusher body causes said pusher plate to press the rod into the earth.
