Embodiment Construction

[0011] figure 1 The paving machine shown comprises a frame 1 with a crawler traction assembly (wheel mechanisms can also be additionally provided), the frame has a hopper 3 at the front and a spreader screw conveyor 4 at the rear, between which is arranged a Conveyor (not visible) in the area of ​​conveying the mixed material to be laid out of the hopper 3 into the distribution area screw conveyor 4 by means of a conveying shaft on which an upper layer is arranged.

[0012] A floating paving screed 5 for floating laying of the mixture to be laid is hinged on the frame 1 via a stretching arm 6 . The paving screed 5 is located behind the spreader screw conveyor 4 in the laying direction and may comprise a basic screed 7 and, if desired, an extendable screed 8 which is transversely extendable and independent of each other. The basic screed 7 is divided in the middle in a conventional manner, and the two halves of the screed 7 can be tilted relative to each other in order to prov...

Abstract

The invention relates to a paving screed for a paver, with a basic screed and with at least one lateral extendable screed part which is connected to the basic screed via hydraulically actuable tensioners and the height of which can be adjusted by means of a height setting device which comprises vertical spindles which are coupled to the extendable screed part and are held on the basic screed rotatably relative to the latter, the spindles being adjustable via a common drive motor, it being possible, as a result of the actuation of the drive motor, to trigger a release of the hydraulically actuable tensioners for the duration of actuation and the extendable screed part being additionally connected to the basic screed via spring-biased screws.

Description

technical field [0001] The invention relates to a paving screed for path construction and of a paving machine equipped with a floating screed. Background technique [0002] Where the paving machine is provided with a frame and with a towed floating paving screed articulated to the latter via extension arms, the set angle of said screed relative to the ground can be set by means of an actuating cylinder and comprising at least one surface In the case of ground-based panels, the mix is ​​introduced via the front hopper, conveyed by conveyor into the area in front of the paving screed and distributed over the width of the screed by a distributor screw conveyor to then be laid by the paving screed. [0003] In order to lay larger widths, the basic screed of the paving screed can be widened by an extended extendable screed section and / or by a screed extension connected to the extendable screed section. It is known in this connection that an extendable screed sec...
