The invention discloses a flexible auger delivery mechanism applied to the industries of electricity, mine, cement and metallurgy, which consists of an auger body, elastic blades and protection chain. The elastic blades and the protection chain are fixed on the auger body; the inside of the auger is used for venting or conveying other media for one time, the outside of the auger is provided with the fixed chain; the elastic blade is made of hard wearing armor plate and is suspended at the offside of the auger body, the elastic blade and the protection chains are flexibly jointed and dischargematerial through rotation; the protection chains are used for connecting the auger body and the elastic blade, so as to make the elastic blade float at the offside of the auger body. By adopting the flexible joint structure, the invention has novel structure, and realizes vertical feeding. The invention further can effectively avoid block which can cause damage to the auger convey mechanism or material block. The materials are made of hard wearing armor plate which provides excellent wearing resistance and long service life.
