Anti-segregation screw distributor and paver

Abstract

The invention discloses a segregation-preventing spiral distributor and a paver, wherein the anti-segregation spiral distributor is arranged on the paver, including left and right spirals and a spiral drive sprocket box, wherein the spiral drive sprocket box A plow-shaped distributing device for distributing the mixed material entering the anti-segregation screw distributor to both sides is arranged in front. The anti-segregation screw distributor and paver of the present invention have the beneficial effects of the following aspects: its plow-shaped material distributor can effectively regulate the flow of the mixture, so that the asphalt mixture can be effectively stirred, and the mixture can be reduced in the spiral. Drive the accumulation and extrusion at the bottom of the sprocket box, reduce the longitudinal segregation of asphalt mixture, and improve the paving quality of the road surface after paving.

Description

technical field [0001] The invention relates to a spiral feeder, in particular to a segregation-preventing spiral feeder and a paver with the segregation-preventing spiral feeder. Background technique [0002] With the continuous improvement of road construction technology and the continuous improvement of road surface quality requirements, the application and status of asphalt concrete paver has been paid more and more attention. more attention. There are many reasons for pavement segregation. Pavement segregation caused by asphalt paver mainly includes hopper segregation, spiral mixing segregation, rammer tamping segregation, screed paving segregation and random segregation. [0003] For the asphalt paver, conveying and distributing the mixture is accomplished by two important components, the scraper and the auger. The scraper is a translational layered conveying device, which will not re-stir and mix the mixture, so the physical and temperature segregation of the mixtur...

AI Technical Summary

Problems solved by technology

This is due to the space interference of the spiral drive sprocket box, so that the left and right spirals are separated by a certain distance at the middle seam. The mixture at this break cannot be evenly spread and stirred by the spiral, and will be at the bottom of the spiral drive sprocket box. Accumulation and extrusion occur, and only rely on the natural flow of the mixture to fill. After paving, the density is very low and the gradation is uneven, forming an obvious strip-shaped segregation zone
