Helical blade, helical material divider and spreading machine

Abstract

The invention discloses a helical blade, a helical material divider, and a spreading machine. The helical blade comprises a helical blade body and wear-resisting pieces in dismountable connection with the helical blade body, wherein the wear-resisting pieces are matched with the helical surface of the helical blade body and are mounted on the helical surface of the helical blade body. According to the helical blade, the helical material divider and the spreading machine provided by the invention, edge wear-resisting tendons easy to replace are mounted on sites which are seriously worn on the edge of the helical blade body; particularly in the seriously-worn construction places wherein broken stones exist, the service life of the helical blade can be greatly prolonged, and the use value is high.

Description

technical field [0001] The invention relates to a spiral blade used for a spiral distributor, in particular to a spiral blade with detachable wear parts, a spiral distributor and a paver. Background technique [0002] Paver is an indispensable special equipment for building general roads and high-grade roads. The spiral blade is an important part of the paver, and its main function is to separate the asphalt mixture sent by the scraper conveyor to the two ends of the trough; among them, the wear resistance of the spiral blade is the main factor to measure the service life of the spiral blade Performance. Usually the reason for replacing the screw blade is that on the one hand, the screw blade is broken and damaged, and on the other hand, the edge of the screw blade is severely worn, and the material cannot be effectively conveyed to both sides of the width to be paved, especially in the asphalt mixture. During the construction process, due to the viscous asphalt mixture st...
