Abstract

The invention discloses a telescopic screed and a paver, comprising a base section screed, a left first telescopic section screed, a right first telescopic section screed, a left second telescopic section screed, and a right second telescopic section screed flat plate, the left first telescopic section screed and the right first telescopic section screed are respectively connected to the base section screed through the left first telescopic guide mechanism and the right first telescopic guide mechanism, and can move laterally relative to the base section screed . The invention provides a telescopic screed whose width when fully extended reaches three times of the basic width, so that the need for large-width paving can be met only through the expansion and contraction of the screed without disassembling and assembling the extension section, and the construction convenience is remarkably improved. sex.

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 to compact, smooth and shape the road surface. According to the different ways of width expansion, screeds can usually be divided into hydraulic expansion screeds and mechanically assembled screeds. The mechanically assembled screed realizes different working widths by assembling lengthened sections of different widths with fasteners, and the hydraulic telescopic screed is made to expand and contract laterally (that is, perpendicular to the advancing direction of the paver) relative to the base section screed. The working width can be easily changed. [0003] The most common telescopic screed at present has a width of about twice the width of the base when fully extended. The screed includes a base section screed and a base section screed on the sa...
