Abstract
A forwards and reversible vibratory pothole packer includes a rotatable eccentric element shaft; a number of pulleys and linkages connected to the shaft; the pulleys and linkages changing the direction of the shaft. As a result, clockwise direction rotation of the shaft causes the drum to rotate in a counter clockwise direction thereby providing reverse direction of the unit and also counter-clockwise rotation of the shaft causes the drum will be propelled forwards. Thus, linear motion of the unit is reversed.
Claims7
A forward and reversible self-propelled vibratory pothole packer, comprising:
- a drum;
- a rotatable eccentric element shaft disposed within the drum;
- and
- a plurality of pulleys and linkages connected to the shaft, the pulleys and linkages changing the direction of the shaft;
- wherein clockwise direction rotation of the shaft causes the drum to rotate in a counter clockwise direction thereby providing reverse direction of the unit as a function of an angular velocity of the shaft;
- wherein counter-clockwise rotation of the shaft causes the drum to be propelled forwards as a function of the angular velocity of the shaft;
- wherein rotation of the eccentric element shaft creates a vibratory force on the drum;
- and
- wherein the drum is not driven directly by the engine.
