Abstract
An injection implement for introducing chemicals to subsurface areas which includes a ground penetrating bit and a fluid injector which are hydraulically operated so as to slectively penetrate the earth's surface and which also includes a chemical supply circuit and tamping mechanism for initially introducing chemcials to the injector under pressure and thereafter closing the opening in the earth's surface created by the penetrating bit and fluid injector so as to prevent the escape of chemicals to the atmosphere.
Claims18
An apparatus for injecting chemicals into the earth and which is mounted to a vehicle having a power system comprising an earth penetrating bit mounted to the vehicle, said bit having upper and lower ends and an elongated axis, a dispensing nozzle means mounted to said bit and terminating in spaced relationship from said lower end thereof, power means for selectively moving said bit from a first elevated position to a second position in which said lower end and said dispensing nozzle means penetrates the earth to create a bore therein, chemical supply means, mounting means for mounting said chemical supply means relative to the vehicle, first conduit means connecting said chemical supply means to said nozzle means, tamping means mounted to the vehicle adjacent said bit, means for guiding said tamping means from a first position spaced from the axis of said bit to a second position in contact with the earth and intersecting the axis of said bit so as to close the bore therein, and means for supplying chemical from said supply means and through said first conduit means to said nozzle means, whereby when said bit is in said second position chemical from said supply means may be supplied to said nozzle means and when said bit is elevated to said first position said tamping means may be moved to said second position to close the bore created by said bit.
An apparatus for injecting chemicals into the earth and which is mounted to a vehicle having an auxiliary power system which includes a hydraulic system comprising a first hydraulic cylinder mounted to the vehicle, said first hydraulic cylinder having an extendable rod, a combination earth penetrating bit and fluid nozzle mounted to said extendable rod, said combination bit and nozzle means having upper and lower ends which are aligned along an elongated axis, said bit being movable from a first elevated position to a second position in which said combination bit and nozzle means penetrate the earth to create a bore therein, chemical supply means mounted in fixed relationship to the vehicle, first conduit means connecting said chemical supply means to said combination bit and nozzle means, tamping means mounted the vehicle adjacent said combination bit and nozzle means, guide means for guiding said tamping means from a first position spaced from the axis of said combination bit and nozzle means to a second position in contact with the earth and intersecting the axis of said combination bit and nozzle means, and means for supplying chemical from said supply means and through said first conduit means to said combination bit and nozzle means, whereby when said combination bit and nozzle means are elevated to said first position said tamping means is moved to said second position to close the bore created by said combination bit and nozzle means.
