MIXTURE AGITATOR Russian patent published in 1997 - IPC

FIELD: construction engineering, food processing industry, various mixers. SUBSTANCE: agitator has shell 1 mounted to rotate relative to base 2. The lower portion of the agitator is spherical. The shell accommodates blades 3 of shaft 4 which are installed to rotate round axes perpendicular to the axis of rotation of this shaft secured concentrically in end face cam 5 and provided with roller 6. The roller contacts the end face cam made integral with gear wheel 7 linked kinematically with motor 8 through reduction gear 9. Blades 3 are provided with projections 10 and are adopted to contact spring-loaded ring 11, which interacts with limit switch 12 intended to stop the motor after the stirring of mixture is finished. At the same time spring-loaded ring 11, installed in the shell for forward motion, is linked with leverage system 13 responsible for turning the shell to pour out the stirred mixture. The shell returns into its working position due to displacement of the center of mass of the motor and reduction gear relative to the axis of rotation of the shell. EFFECT: improved efficiency. 1 dwg
