Vibratory pothole packer

摘要

A vibratory pothole packer includes a frame that supports an engine and a rotatable drum, and a rotatable eccentric shaft is supported within the drum. The eccentric shaft may be a drum shaft with a mass welded to its surface. The eccentric shaft is supported within the drum by bearings, and is also supported on the frame by bearings. The engine shaft can be selectively linked with eccentric shaft to selectively effect vibrational rotation of the eccentric shaft. The small, lightweight pothole packer is manually movable on a surface by one person, and can be moved along a surface either while the eccentric shaft rotates or while the eccentric shaft is not rotating. The center of mass of the eccentric shaft is offset towards one end of the shaft to allow the vibratory pothole packer to be easily moved in a straight line along a surface.

主权项

1. A vibratory pothole packer, comprising:
a frame having an outer frame wall, the frame further having a mounting channel, and the outer frame wall further comprising at least one side plate secured to the mounting channel; an engine secured to the mounting channel, the engine further comprising an engine shaft; at least one shock absorber secured to the at least one side plate; at least one shock absorber plate secured to the at least one shock absorber; at least one set of shock absorber plate bearings secured to the at least one shock absorber plate; a drum, the drum having an outer wall with a substantially cylindrical outer surface, the outer wall having an inner surface that defines a cavity within the drum; an eccentric shaft, the eccentric shaft having a first end and a second end, the eccentric shaft having a center of mass that is positioned closer to the first end of the eccentric shaft than to the second end of the eccentric shaft, the eccentric shaft being supported within the cavity of the drum by at least one set of drum bearings that are secured to the drum; and the eccentric shaft being supported by the shock absorber plate bearings, whereby the at least one shock absorber and at least one shock absorber plate prevent vibration from the centrifugal force of the eccentric shaft to travel into the frame and the engine wherein the rotation of the engine shaft can be selectively linked to the rotation of the eccentric shaft.
