Embodiment Construction

[0036] 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.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0038] The present invention firstly provides a telescopic screed structure, including a main screed 10 and an auxiliary screed 20 that can be mutually retracted, and the telescopic screed structure also includes a floating baffle 30, a guide 40 and an elastic member 50, so The guide 40 is arranged on the main screed 10 , the floating baffle 30 is slidably arranged along the guide 40 , and is biased by the elastic member 50 and abuts against the auxiliary screed 20 superior.

[0039] In the above technical solution, because the floating ba...

Abstract

The invention provides a retractable screed plate structure which comprises a main screed plate (10), an accessory screed plate (20), a floating barrier (30), a guide component (40) and an elastic component (50), wherein the main screed plate (10) and the accessory screed plate (20) are mutually retractable; the guide component (40) is arranged on the main screed plate (10); the floating barrier (30) is slidably arranged along the guide component (40), and biased and abutted against the accessory screed plate (20) by virtue of the elastic component (50). The invention also provides a paver with the retractable screed plate structure. By using the retractable screed plate structure and spreader provided by the invention, a mixture in front of the accessory screed plate can be effectively prevented from leaking into the main screed plate, thereby improving the paving quality of a road surface.

Description

technical field [0001] The invention relates to the field of road construction machinery, more specifically, to a telescopic screed structure and a paver with the telescopic screed structure. Background technique [0002] At present, the retractable screed structure of the paver usually adopts such as figure 1 As shown in the font layout, the main screed 10 is in front, and the left and right auxiliary screeds 20 are behind. Front sides of the main screed 10 and the left and right auxiliary screeds 20 respectively have tamper system front baffles (may be simply referred to as front baffles) 12 and 22 . [0003] Since the auxiliary screed 20 needs to move telescopically relative to the main screed 10 within a certain range, there is a certain gap between the main screed 10 and the auxiliary screed 20 (such as figure 2 Gap A and Gap B shown). [0004] In order to prevent the mixture in front of the auxiliary screed 20 from leaking into the back of the main screed 10 from t...
