ROTARY FEEDER FOR GRANULAR MATERIAL Russian patent published in 2019 - IPC B65G53/46 B65G65/48 

FIELD: machine building.

SUBSTANCE: invention relates to loose materials feeding and batching devices and to continuous action dosing units operating on a volume principle, can be used in food, construction, pharmaceutical, chemical and other industries. Rotary feeder for bulk material includes a housing, a rotating conical rotor installed on the shaft in the housing, which is made cylindrical outside and conical inside. On the cylindrical surface of the housing there is an inlet channel for receiving bulk material from above, and from below an outlet channel is made for unloading loose material from the rotary feeder, as well as sealing flanges. On one end of the shaft, a cylindrical driving gear is rigidly fixed to transfer rotation of the shaft from the drive, wherein rotary rotor is made in form of two connected to each other conical drums, mounted on shaft, which are centered inside housing on one side of bearing unit. Driving gear is made replaceable, and in front of cylindrical driving replaceable gear there is thrust bushing for interaction with end of one of drums for provision of gap between one of flanges and end of this drum at wear of these parts. On surface of conical drums there are dosing holes located at equal distance from each other along circumference and along the length, which are gripping elements.

EFFECT: increase the dispensing efficiency and accuracy.
