Scraper plate device of spreading machine

Abstract

The invention discloses a scraper plate device of a spreading machine and relates to the technical field of spreading machine manufacturing. The scraper plate device comprises a chain wound on a chain wheel; the chain is formed by alternatively pivoting a plurality of outer chain plates and inner chain plates; each outer chain plate is formed by connecting a sealing plate and outer chain plate side plates arranged at the two sides of the sealing plate, and each sealing plate is arranged at the outer edge of the chain; each chain plate is formed by connecting a bent plate and inner chain plate side plates arranged at the two sides of the bent plate, and each bent plate is arranged at the outer edge of the chain; and the two ends of each inner chain plate respectively stretch into the two ends of the adjacent outer chain plates and are pivoted with the outer chain plates through chain pins which penetrate through a sleeve. Compared with the prior art, the bent plates and the sealing plates are arranged at the outer edge of the chain so that the outer edge and the two side faces of the chain are sealed; and the inner edge of the chain of the upper-row part of the chain is tightly clung to a wear-resisting plate on a frame so as to prevent fine mixtures from entering the chain, greatly reduce the phenomenon of chain clamping and improve the working efficiency of the spreading machine and the reliability of the whole machine.

Description

technical field [0001] The invention relates to the technical field of paver manufacturing, in particular to a scraper device for a paver. Background technique [0002] The paver is mainly a construction equipment used for paving various materials on the base and surface of the expressway. The function of the scraper device is to transport the mixture from the hopper at the front end of the paver to the paving tank at the rear end. Such as figure 1 Shown is a paver scraper device, the paver scraper device includes a chain that surrounds the sprocket, and the chain is alternately pivoted by a plurality of outer chain plates and inner chain plates through chain pins. The outer chain plate and the inner chain plate both have chain plates arranged at both ends of the sleeve; scrapers are distributed at intervals on both sides of the outer chain plate of the chain; A baffle plate is arranged above the outer edge of the part of the chain. This paver scraper device has the follo...

AI Technical Summary

Problems solved by technology

This paver scraper device has the following deficiencies during use: 1. There is a certain distance between the baffle above the chain and the outer edge of the chain. When the paver scraper device is working, small mixture often enters the outside. In the two chain plates of the chain plate and the inner chain plate, the chain is stuck, which reduces the working efficiency of the paver; 2. The installation of the baffle takes up a lot of space and is difficult to maintain
