Paver head assembly
This application is for an improved paver head for smoothing and finishing poured concrete surfaces. It includes a strike-off plow for initial leveling of concrete, an auger for mixing and smoothing surface imperfections, a roller for smoothing and leveling, and a finish blade for final surface finishing of a poured concrete surface.
1. A paver head for use with a concrete screeder for screeding poured concrete to produce a level finished surface comprising:
a mounting assembly having a frame for securing said paver head to said concrete screeder;
a plow secured to said frame at a rear portion thereof for initial grading of said concrete;
an auger secured to said frame forward of and adjacent to said plow, said auger journaled for rotation around a central longitudinal axis;
a roller secured to said frame forward of and adjacent to said auger and journaled for rotation around a central longitudinal axis to smooth said concrete; and
a finish blade secured to said frame forward of and adjacent to said roller, said finish blade having a finish surface for contacting and smoothing said concrete.
2. A paver head as claimed in claim 1 wherein said finish blade comprises:
a vibration system secured to said finish blade for smoothing said concrete.
3. A paver head as claimed in claim 1 wherein said roller is secured to said frame adjacent to said plow and said auger is secured to said frame between said roller and said finish blade.
4. A paver head as claimed in claim 1 wherein said finish blade is secured to said frame by a plurality of brackets that permit adjustment of the height and angle of said finish blade surface relative to said concrete.
5. A paver head as claimed in claim 1 wherein said auger comprises:
a cylinder having a helical blade secured to and extending therefrom.
6. A paver head as claimed in claim 1 wherein said auger comprises:
a cylinder having a first helical blade secured to and extending therefrom along substantially the length of said cylinder; and
a second helical blade secured to and extending from said cylinder along a portion thereof.
7. A paver head as claimed in claim 1 comprising:
a drive motor secured to said frame at an end thereof, said drive motor rotating a shaft secured to a sprocket;
a sprocket secured to each of said auger and said roller; and
a chain connecting said drive motor sprocket to said auger and roller sprockets, thereby providing rotation to said roller and auger.
8. A paver head as claimed in claim 2 comprising:
a vibration rod secured to said finish blade and journaled for rotation;
at least one eccentric weight secured to said vibration rod; and
a vibrator motor having a shaft secured to said vibration rod for rotating said rod and thereby providing vibratory force to said finish blade.
9. A paver head as claimed in claim 7 wherein said drive motor is an hydraulic motor.
10. A paver head as claimed in claim 8 wherein said vibrator motor is an hydraulic motor.
11. A paver head for use with a concrete screeder for screeding poured concrete to produce a level finished surface comprising:
a frame for securing said paver head to said concrete screeder;
a plow vertically adjustably secured to said frame at a rear portion thereof for initial grading of said concrete;
an auger having an helical blade extending therefrom, said auger rotatably secured to said frame forward of and adjacent to said plow;
a cylindrical roller rotatably secured to said frame forward of and adjacent to said auger to smooth said concrete; and
a finish blade adjustably secured to said frame forward of and adjacent to said roller, said finish blade having a finish surface for contacting and smoothing said concrete.
12. The paver head of claim 11 wherein said auger and said roller are comprised of hardened steel.
13. The paver head of claim 11 further comprising:
a vibration system secured to said paver head for imparting vibratory force to said finish blade.
14. A paver head for use with a concrete screeder for screeding poured concrete to produce a level finished surface comprising:
a frame for securing said paver head to said concrete screeder;
a plow adjustably secured to said frame at a rear portion thereof for initial grading of said concrete;
an auger having an helical blade extending therefrom, said auger rotatably secured to said frame forward of and adjacent to said plow;
a cylindrical roller rotatably secured to said frame forward of and adjacent to said auger to smooth said concrete;
a drive motor having a rotating shaft and concomitant sprocket, said sprocket connected to said rotatable auger and roller to provide rotation thereto; and
a finish blade adjustably secured to said frame forward of and adjacent to said roller, said finish blade having a finish surface for contacting and smoothing said concrete.
