Embodiment Construction

[0031] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited to the following embodiments.

[0032] like figure 1 In the pumping distributor of the pavement paver shown, the rear hopper 1 is placed under the rear end of the scraper conveyor belt 2, and the pavement mixture conveyed by the scraper conveyor belt is loaded into the rear hopper. The width of the upper opening of the rear hopper should be greater than the width of the scraper conveyor belt, and the depth of the hopper should be greater than 400mm; the bottom of the rear hopper is connected to a horizontally arranged semi-circular steel pipe 3. The recommended inner diameter of the semi-circular steel pipe is 300mm, length 1000mm, and wall thickness 10mm. The semi-circular steel pipe is provided with a long groove extending along the busbar (on the cross-section of the semi-circular steel pipe, the central ...

Abstract

The invention relates to construction equipment for public facilities. The purpose is to provide a pumping distributor for road paver, which should be able to effectively solve the problem of lateral segregation of pavement mixture caused by the screw distributor, slow distribution of materials restricting the paving speed, and convenient assembly and disassembly, and simple cleaning. . The technical scheme is: a pumping distributor for a road paver, characterized in that: the distributor comprises a semicircular steel pipe arranged below the rear hopper and arranged horizontally to receive the road mixture released by the rear hopper, and can be arranged along the semicircle. The steel pipe is axially moved to pump the piston of the road mixture, the first hydraulic cylinder that drives the piston, and the two axial ends of the semi-circular steel pipe are connected in series in a coaxial line, and each is provided with an opening extending along the bus bar for conveying the road mixture. Several sections of open steel pipes.

Description

technical field [0001] The invention relates to construction equipment for public facilities, in particular to a road paving machine distributor. Background technique [0002] Asphalt pavement segregation refers to the non-uniformity of the main properties of the asphalt mixture in a certain area of ​​the pavement, including the amount of asphalt, gradation composition, additive content, and uneven porosity of the pavement, which accelerates the damage to the asphalt pavement. Some early damages of highway asphalt pavement, such as network cracks, deformation and potholes caused by water damage, local severe rutting, local oil flooding, many lateral cracks, uneven structural depth of newly laid asphalt pavement, etc., are mixed with asphalt. Segregation of materials. [0003] The pavement is a layered structure, and the pavement structure is mainly paved with paver. At present, pavement structure paver mainly includes asphalt surface layer mixture LT type paver and pavemen...
