Description

Technical Field

[0001] The utility model relates to the technical field of bulk material conveying, in particular to a quantitative feeding device. Background Art

[0002] The quantitative feeder is an ideal equipment for continuous weighing and feeding of bulk materials. It is a high-tech product integrating transportation, weighing and quantitative control. It is famous for its advanced technology, stability and reliability, high cost performance and durability. It can adapt to various production environments, and continuously feed and measure various block and granular materials (such as limestone, iron powder) and powdered materials (such as fly ash, cement), etc., and provide accurate measurement data for production control and management of various industrial sites. Quantitative feeders are widely used in building materials, metallurgy, electric power, chemical industry, coal, coking, mining, tobacco, food, environmental protection, ports and other industries.

[0003] Announcement No. CN220548517U discloses a quantitative feeding device for kneading machine additives. The additives are poured into the discharge box from the feed hopper, and the discharge tray on the outside of the shaft is driven to rotate by a driving motor. Since the outer surface of the discharge tray abuts against the inner surface of the cavity, the materials fall into the receiving trough of the discharge tray in turn. As the discharge tray rotates, the materials fall from the receiving trough into the cavity and slide out from the corresponding guide trough, thereby achieving the purpose of constant volume feeding.

[0004] However, in the above scheme, since the size of the receiving trough is fixed, it can only feed materials with a size that is a multiple of the receiving trough when in use, and cannot feed materials between multiple sizes, and its scope of application is greatly limited.

[0005] Therefore, we propose a quantitative feeding device to solve the above problems. Utility Model Content
