Scraper conveyor for efficiently conveying materials

Abstract

The invention relates to the technical field of engineering machinery, and discloses a scraper conveyor for efficiently conveying materials, which comprises a conveying chain, a transmission wheel is movably connected to the inner side of the corner of the conveying chain, and scrapers are fixedly mounted on the two axial sides of the conveying chain at equal intervals respectively. The side, facing the conveying direction, of each scraper is fixedly connected with a fixing box, and the inner side of each scraper is slidably connected with a piston plate. A fixed box is arranged on one side of a scraper, the scraper is communicated with the fixed box, a piston plate always moves towards the ground on the inner side of the scraper, airflow in an inner cavity of the scraper enters the inner side of the fixed box through a fixed hole, and a fixed supporting plate on the inner side of the fixed box extends upwards on the inner side of the fixed box; therefore, the one-time transportation effective area of the scraper blade is increased, the materials are prevented from falling back during oblique conveying, the fixed supporting plate which retracts from the upper portion cannot scrape the materials conveyed by the fixed supporting plate below, and the conveying amount is further increased.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a scraper conveyor for efficient material conveying. Background technique [0002] The scraper conveyor is composed of three parts: the nose, the middle part and the tail of the machine. In addition, there are hydraulic jacks for pushing the conveyor and chain tensioners for tightening the chain. The middle part is composed of transitional parts. The trough, the middle trough, the chain and the scraper are composed of components, of which both ends of the middle part, namely the nose and the tail, are devices for the scraper chain to return, and according to the arrangement and structure of the scraper conveyor chute, it can be divided into There are two types of side-by-side and overlapping types. According to the number and arrangement of chains, they can be divided into single-chain, double-sided, double-center and triple-chain. The single-chain chain is located...
