Embodiment Construction

[0024] figure 1 A schematic top view showing the main components of a paving machine F, in particular a paving machine F for work with larger working widths. The tractor 1 has a chassis (not shown in detail) and an undercarriage 2 . On the rear side 3 of the chassis at least one distribution screw 4 is arranged in a vertical rail 8 so that the distribution screw 4 can be adjusted in its height position by means of a remote control drive 7 . The distribution screw support 4 is functionally connected to a rotary drive not shown in detail and carries a distribution screw 6 with a screw shaft 5 , positioning the distribution screw and the screw shaft laterally behind the tractor 1 . Optionally, two adjacent distributing screw supports 4 are provided for the two distributing screw halves, each support being adjustable in its height direction (not shown).

Abstract

A road paver (F) has a paving screed E the working width of which can be adjusted continuously. In order to further enlarge the working width in steps at least one paving screed extension can be mounted. A distributing auger (6) is supported in a distributing auger support (4). Distributing auger extensions (19a, 19b, 19c) can be mounted to the distributing auger (6). Scraper blades (20) are arranged in casting travelling direction behind distributing auger (6). At least a scraper blade section (20a) functionally associated to a mounted paving screed extension (13) is carried by a channel sheet steel plate (15) being part of the mounted distributing auger extension (19a, 19b, 19c). The scraper blade section (20a) can be adjusted in height direction together with the distributing auger support (4) via a drive (7) which can be remotely controlled during a casting process.

Description

technical field [0001] The invention relates to a paving machine according to the preamble of claim 1 . Background technique [0002] It is known in practice for paving machines to initially roughly pre-adjust the height of the paving material in front of the distribution auger. The distribution of the paving material produced by the paving auger is then also precisely adjusted during casting by adjusting the distribution auger and adjusting the helical support in height direction at the rear side of the tractor chassis for passing the paving screed Change the corresponding thickness of the casting layer. In the case of larger working widths, the distribution auger is lengthened by installing a distribution auger extension. The extended screed section of the paving screed is lengthened correspondingly by installing the extension. The distribution screw extension is arranged with the channel-shaped sheet metal and is supported in front of the paving screed in the direction...
