Device for inserting dowels into freshly laid road surfaces
First Claim
1. A device for inserting dowels (2) in the vicinity of transverse expansion joints of freshly laid concrete road surfaces (4), comprisinga machine frame (8) supported by traveling mechanisms (6), at least one storage container (10,12) for the-dowels (2), a smoothing board (20) resting on the road surface (4) and including slots (24) running in a direction of travel and provided for accommodating the dowels (2), a retaining device (28) for the dowels associated with each of the slots (24), a continuous line conveyor device (40) disposed in transverse spanning relationship to the direction of travel and in alignment with a discharge area of said at least one storage container (10, 12), said conveyor device (40) including means (70) for directly receiving dowels (2) from an indiscriminately arranged stack of side-by-side dowels at said storage chamber discharge area along a first run portion of said conveyor device (40) and distributing said dowels (2) to the slots (24) along a second run portion of said conveyor device (40), said conveyor device second run portion extending above said slots (24), and means (34) movable through a plane defined by the conveyor device second run portion for pushing dowels (2) into a freshly laid concrete road surface.

Abstract
In a device for inserting dowels (2) in the vicinity of transverse expansion joints of freshly laid concrete road surfaces (4), comprising a machine frame (8) supported by traveling mechanisms (6), at least one storage container (10,12) for the dowels (2), a smoothing board (20) resting on the road surface (4) and including slits (24) running in a direction of travel and provided for accommodating the dowels (2), a retaining device (28) for the dowels on the slots (24), and a dowel placing device (32), it is provided that a line conveyor device (40) accepts separated dowels (2) in a section (44) of a bottom or lateral area (48,52) of the storage container (10,12) and delivers the dowels (2) to the slots in the smoothing board (20).
