Abstract
A vibratory unit interposed between a planetary drive and earth-penetrating device, e.g., an auger, is powered by the hydraulic system of a tractor, skid loader or the like. The unit includes a housing having a base plate with a slidable striker plate mounted therein. A Kelly bar displaces the planetary drive from the auger and through the housing. A rotatable shaft with weights eccentrically mounted thereon produces vibratory forces and urges the striker plate into contact with the base plate to provide hammer-like forces on the auger.
Claims15
A vibratory unit for an earth-penetrating device powered by a drive system, said unit comprising:
- a housing including a base plate;
- a mounting plate within said housing;
- means for slidably moving said mounting plate towards and away from said base plate;
- a rotatable shaft on said mounting plate;
- at least one weight eccentrically mounted about said shaft;
- a motor;
- means for associating said motor with said mounting plate;
- means for coupling said motor to said shaft;
- means for powering said motor whereby to rotate said shaft;
- an extension bar extending through said housing and presenting a first end beyond said housing and a second end beyond said base plate;
- means for coupling said first end of said bar to the drive system;
- means for coupling the second end of said bar to the earth-penetrating device, said housing interposed between the drive system and earth-penetrating device with said extension bar passing therethrough, a powering of the drive system transmitted to the earth-penetrating device coupled thereto by said bar;
- a powering of said motor rotating said shaft and said at least one weight thereon producing vibratory forces and forces for urging said mounting plate into said slidable movement for contact with said base plate, said contact providing an impulse force on the earth-penetrating device whereby said forces enhance penetration.
A vibratory unit for use with an earth-penetrating device and a drive system for operating the device, said unit comprising:
- a base plate;
- a striker plate;
- means for slidably mounting said striker plate towards and away from said base plate;
- a rotatable shaft on said striker plate;
- at least one weight eccentrically positioned on said shaft;
- a motor for rotating said shaft;
- an extension bar extending through said base plate and striker plate and presenting a first end beyond said striker plate and a second end beyond said base plate, said striker plate movable along said extension bar;
- means for coupling said first end of said bar to the drive system;
- means for coupling the second end of said bar to the earth-penetrating device, a powering of the drive system operating the earth-penetrating device coupled thereto by means of said extension bar;
- a powering of said motor rotating said shaft and said at least one weight thereon, said shaft rotation providing vibratory forces and urging said striker plate into said slidable movement for contact with said base plate, said contact providing an impulse force on the earth-penetrating device whereby to enhance its penetration.
A vibratory unit for use with an auger and a drive system for rotating the auger, said unit comprising:
- a housing including a base plate;
- a mounting plate;
- means for guiding said mounting plate in movement towards and away from said base plate;
- a rotatable shaft on said mounting plate;
- at least one weight eccentrically mounted to said shaft relative to a central axis passing through said shaft;
- a motor, said motor rotating said shaft upon operation of said motor;
- an extension bar extending through said housing and presenting a first end and a second end;
- means for coupling said first end of said bar to the drive system;
- means for coupling the second end of said bar to the auger, a powering of the drive system rotating the bar and the auger coupled thereto;
- a powering of said motor rotating said shaft with said at least one weight thereon, said rotation producing forces for urging the mounting plate in said movement towards and away from said base plate, a movement of said mounting plate towards said base plate providing impulse forces for delivery to the auger, whereby to enhance an earth penetration of the auger.
