Description

Disc coal feeder Technical Field The invention relates to the field of coal transportation, in particular to a disc coal feeder. Background The coal feeder is a key hub for connecting the coal storage unit and subsequent processing equipment in the full-automatic coal sample preparation system, and the feeding performance of the coal feeder directly determines sample preparation effectiveness and analysis result representativeness. According to the relevant national standard, the sample preparation has severe requirements on uniformity and flow control of coal feeding, and in the relevant technology, coal feeding equipment has the problems of coal blocking, coal sticking and the like, and cannot meet the requirements of unmanned and high reliability of an intelligent laboratory. Disclosure of Invention The present invention has been made based on the findings and knowledge of the inventors regarding the following facts and problems: in the related art, coal feeding equipment mainly comprises a disc, a belt and scraper feeding, and the technical limitations are that a CN 202210145679.8 disc feeder is used for processing high-moisture/high-adhesion coal samples and is easy to adhere and a runner is invalid depending on friction force between materials and disc surfaces, and a discharging slide carriage flow guiding effect of the CN202422726393.6 disc feeder is influenced by material flowability and is easy to cause slide carriage blockage.
