Concrete finishing machine with vibrating compactor unit

In a concrete finishing machine of the type embodying an elongated main frame adapted for movement longitudinally along a roadway or the like being surfaced, a surfacing unit for finishing a concrete surface, the surfacing unit being adapted for movement back and forth along the main frame laterally of the roadway and including first and second finishing cylinders each rotatably mounted to said main frame and extending in a parallel speed relation, and first and second augers mounted for rotation with said first and second finishing cylinders, respectively and extending in a parallel spaced relation, compacting means comprising:

• a sub-frame;
• first and second compacting rollers;
• vibrating means;
• and mounting means;
• said sub-frame including means for rotatably mounting said compactor rollers in a parallel spaced relation adjacent to said auger, said compacting rollers each comprising an elongated cylinder having projections extending radially from the peripheral edge of said cylinder in a spaced relation around the peripheral edge of the cylinder, each of said projections having first and second generally planar surfaces extending the length of said cylinder,
• said vibrating means coupled to said sub-frame for vibrating same and said compacting rollers supported thereby,
• and said mounting means including suspension means mounting said sub-frame to the main frame of the concrete finishing machine, and isolating means interposed between said suspension means and said sub-frame for preventing transmission of vibrations from said sub-frame to the main frame as said sub-frame is vibrated.

In a concrete finishing machine including frame means supporting a surfacing apparatus for finishing a concrete surface and having means for establishing a desired grade for the finished concrete surface, compacting means comprising:

• a sub-frame;
• at least one compacting roller;
• vibrating means;
• and mounting means;
• said sub-frame including means for rotatably mounting said compacting rollers, said compacting roller comprising an elongated cylinder having projections extending radially from the peripheral edge of said cylinder in a spaced relation around the periphery of said cylinder, each of said projections having first and second generally planar surfaces extending the length of said cylinder,
• said vibrating means coupled to said sub-frame for vibrating same and said compacting roller supported thereby,
• and said mounting means including suspension means mounting said sub-frame to the frame means of the concrete finishing machine with said compacting roller suspended at a height above the concrete surface being finished to provide a desired depth of penetration of said projections into the concrete surface, and isolating means interposed between said suspension means and said sub-frame for preventing the transmission of vibrations from said sub-frame to the frame means of the concrete finishing machine as said sub-frame is vibrated.

In a concrete finishing machine of the type embodying an elongated main fram eadapted for movement longitudinally along the roadway or the like being surfaced and a surfacing unit for finishing a concrete surface, the surfacing unit being adapted for movement back and forth along the main frame laterally of the roadway and including finishing cylinder means rotatably mounted to the main frame, compacting means comprising:

• a sub-frame;
• a plurality of compacting rollers;
• vibrating means;
• and mounting means;
• said sub-frame including means for rotatably mounting said compacting rollers in a parallel spaced relation,
• said compacting rollers each comprising an elongated cylinder having projections extending outward radially from the peripheral edge of said cylinder in a spaced relation around the peripheral edge of the cylinder and extending the length of said cylinder,
• said vibrating means coupled to said sub-frame for vibrating same and said compacting rollers supported thereby,
• and said mounting means including suspension means mounting said sub-frame to the main frame of the concrete finishing machine with said compacting rollers suspended at a height above the concrete surface being finished to provide a desired depth of penetration of said projections into the concrete surface, and isolating means interposed between said suspension means and said sub-frame for preventing the transmission of vibrations from said sub-frame to the main frame as said sub-frame is vibrated.
