INSTRUMENT FOR DETERMINING ANGLES OF DEPARTURE OF FLOW TO HORIZON Russian patent published in 2004 - IPC

FIELD: agricultural engineering, in particular, machines for surface application of mineral fertilizer and ameliorants, sprinkler machines etc.

SUBSTANCE: instrument has base, movable plate, regulating screw, column, rocker arm, scales and indicator-pendulum. Scale with rib is pivotally attached to outer end of rocker arm, with rib extending perpendicular to plane of rotation of rocker arm around column. Scale of angle of departure of flow to horizon with indicator-pendulum is pivotally hung to rib by means of rings. Scale of working tool rotation angles and machine inclination angle indicator are mounted on movable plate. Machine inclination angle regulating screw is positioned between base and movable plate at side opposite to horizontal pin. Instrument allows angle of departure of flow from working tool to horizon at different longitudinal side inclinations of machine, angle of design embodiment of working tool, angle of rotation of working tool and modes of departure of flow to be determined. Values of angles of departure of flow to horizon are necessary for calculating distance of departure of particles within spreading sector.

EFFECT: increased efficiency and provision for obtaining of precise data on parameters of agricultural tools.
