Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] Such as figure 2 As shown, one aspect of the present invention provides a mechanically extended screed, which includes at least two screed units 1, wherein the mechanically extended screed also includes a magnetic body 2, and the magnetic body 2 is located between two adjacent screed units 1, so that the two adjacent screed units 1 are connected together by the magnetic force of the magnetic body 2.

[0027] Since the adjacent screed units 1 of the mechanically extended screed are connected by the magnetic body 2, as long as the magnetic body 2 generates magnetic force, the adjacent screed units 1 can be firmly connected together, so that the screed uni...

Abstract

The invention discloses a mechanical lengthening type ironing plate. The mechanical lengthening type ironing plate comprises at least two ironing plate units (1), wherein the mechanical lengthening type ironing plate further comprises a magnetic body (2) positioned between two adjacent ironing plate units (1), thus, the two adjacent ironing plate units (1) can be integrally magnetically connected through the magnetic body (2). The invention also discloses a splicing method for the mechanical lengthening type ironing plate. According to the splicing method, the ironing plate units of the mechanical lengthening type ironing plates can be quickly conveniently assembled and disassembled, and therefore, working efficiency is improved, and structure is simple.

Description

technical field [0001] The invention relates to engineering machinery, in particular to a mechanically extended screed and an assembling method for the mechanically extended screed. Background technique [0002] As the working device of the paver, the screed is installed at the rear of the paver. Its main function is to complete the pre-compacting and ironing tasks of the mixture. The operations of the paver are all performed by the screed. Screeds are generally divided into mechanically extended screeds and hydraulically extended screeds. Mechanically extended screeds are composed of a base plate (the base plate is the minimum paving width) and lengthening sections of different widths connected to both sides of the base plate are connected by bolts. To form the required working width; the hydraulic extension screed relies on the expansion and contraction of the hydraulic cylinder to adjust its working width steplessly according to the width of the roadbed to be paved. For ...
