Vibratory paving screed for a paver
View Patent ↗The invention relates to a vibratory paving screed for a paver, comprising a baseplate and a vibration drive therefor and also comprising a front wall which is mounted upstream of the baseplate in the paving direction, is fixed with respect to the baseplate and engages with the baseplate, in which arrangement the baseplate comprises a section of uniform thickness and, in the region of its front edge, a separate, solid strip which is connected to the section and has a metering slope and a flat run-in bevel situated behind.
1. A vibratory paving screed for a paver, comprising
a baseplate
a vibration drive for the base plate, and
a front wall which is mounted upstream of the baseplate in the paving direction, fixed with respect to the baseplate and engaging with the baseplate,
wherein the baseplate comprises
a section of uniform thickness having a front edge and flat run-in bevel extending from the front edge, and
a separate, solid strip disposed in the region of the front edge of the section of uniform thickness, the strip being connected to the section of uniform thickness and having a metering slope and a bottom face disposed behind the metering slope, the bottom face being substantially flush with the run-in bevel at the front edge of the section of uniform thickness, the strip extending over the section and being mounted against the latter, the strip being heatable by a heater disposed inside the solid strip.
2. The vibratory paving screed according to claim 1 , wherein the metering slope has an angle of about 40° to 50° with respect to the underside of the baseplate.
3. The vibratory paving screed according to claim 1 , wherein the solid strip is height-adjustable with respect to the section.
4. The vibratory paving screed according to claim 1 , wherein a sharp-edged transition is provided between the metering slope and run-in bevel.
5. The vibratory paving screed according to claim 1 , wherein the flat run-in bevel is situated in the front region, as seen in the paving direction, of the section.
6. The vibratory paving screed according to claim 1 , wherein the run-in bevel has an angle of about 4° to 10° with respect to the underside of the baseplate.
7. The vibratory paving screed according to claim 1 , wherein the solid strip has, behind the metering slop, as seen in the paving direction, a parallel face with respect to the baseplate.
8. The vibratory paving screed according to claim 7 , wherein the metering slope merges with the parallel face to form a sharp edge.
9. The vibratory paving screed according to claim 1 , wherein the strip is hardened at least in the sides coming into contact with paving material.
10. The vibratory paving screed according to claim 1 , wherein the strip is heatable.
11. The vibratory paving screed according to claim 1 , wherein the section is heatable.
12. The vibratory paving screed according to claim 1 , wherein the strip is replaceable.
13. The vibratory paving screed according to claim 1 , wherein the strip is fastened by way of mounts to the screed body independently of the section.
14. The vibratory paving screed according to claim 1 , wherein the baseplate is adapted to compact a paving material directed under the baseplate, whereby the strip bottom face extends the section of uniform thickness for compaction of the paving material.
