Embodiment Construction

[0042] figure 1 An inventive road finishing machine 100 is shown according to one embodiment of the invention.

[0043] A road finishing machine generally includes a tractor 102 with a screed 110 attached to the tractor, and a distribution screw 116 . The embodiment of the towing vehicle or tractor 102 should be understood as an example only. The screed can be used with any suitable towing vehicle or tractor used for road improvement.

[0044] In the exemplary embodiment, towing vehicle 102 includes a hopper 121 in which is stored material to be applied to the subsoil, such as asphalt. A conveying system not shown in detail here, optionally with one or more scraper belts, can convey the material from the hopper 121 via the traction vehicle to the screed 110, where the material passes transversely to the direction of travel and in front of the screed. distribution screw for distribution.

[0045] The tow vehicle 102 may also include a cab 122 in which a driver may sit. An ...

Abstract

The invention relates to a channel plate arrangement (101) for a road finishing machine (100), an extension device (115) being arranged on the channel plate arrangement, the extension device comprising a first channel plate (151) which is movably mounted in a horizontal direction with respect to the channel plate arrangement (101) in order to variably adjust an effective width of the channel plate arrangement (101), and wherein the extension device (115) comprises a second channel plate (152) which is movably mounted in a horizontal direction with respect to the channel plate arrangement (101) in order to variably adjust the effective width of the channel plate arrangement (101). A second channel plate (152) is connected to the first channel plate (151), and the second channel plate is pivotally arranged at the first channel plate to variably adjust an effective width of the channel plate arrangement (101).

Description

technical field [0001] The invention relates to a channel plate arrangement for a road finishing machine according to claim 1 and to a road finishing machine according to claim 12 . Background technique [0002] Road finishing machines are well known in the art. In order to increase its applicability, screeds have been designed which can be varied with respect to their working width. The working width is the width across which the screed spreads material over the subsoil. [0003] For example, EP 2 169 117 A1 discloses a corresponding screed whose working width is continuously variable. [0004] Since by adjusting the working width of the screed, the width of the applied material also changes, it is possible to over-apply material ahead of the distribution screw in the direction of travel of the road finishing machine with which the screed is used. [0005] To avoid this, EP 2 169 117 A1 proposes a mountable channel plate, which can be provided, for example, as part of a ...
