Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0032] Such as Figure 1 to Figure 7 Shown: This embodiment discloses a telescopic screed, including a base section screed 1, a left first telescopic section screed 2, a right first telescopic section screed 3, a left second telescopic section screed 4, a right The second telescopic segment screed 5, the first left telescopic guide mechanism 6, and the first right telescopic guide mechanism 7.

[0033] The left and right sides of the base section screed 1 are respectively provided with guide holes 2 11, and the left first telescopic guide mechanism 6 and the right first telescopic guide mechanism 7 respectively include a left telescopic suspension 61, a right telescopic suspension 71 and a guid...

Abstract

The invention discloses a telescopic screed and a paver. The telescopic screed comprises a base section screed, a left first telescopic section screed, a right first telescopic section screed, a leftsecond telescopic section screed and a right second telescopic section screed, the left first telescopic section screed and the right first telescopic section screed are connected with the base section screed through a left first telescopic guide mechanism and a right first telescopic guide mechanism respectively and can transversely move relative to the base section screed. According to the telescopic screed, the width of the telescopic screed reaches three times of the basic width when the telescopic screed completely stretches out, so that the requirement for large-width paving can be met only through stretching out and drawing back of the screed plate without disassembling and assembling a lengthened section, and the construction convenience is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of paver, in particular to a telescopic screed and a paver. Background technique [0002] The screed is a very important working device on the paver. It is used for compacting, smoothing and shaping the road surface. It often has devices such as a screed frame, a bottom plate, a vibrating mechanism, and a vibrating mechanism. According to the different ways of width expansion, screeds can generally be divided into hydraulically extendable screeds and mechanical assembled screeds. The mechanical assembled screed achieves different working widths by using fasteners to assemble extensions of different widths, and the hydraulic telescopic screed expands and contracts laterally (that is, perpendicular to the forward direction of the paver) by making the screed of the telescopic section relative to the screed of the basic section The working width can be easily changed. [0003] At present, the width of the most...
