TUBULAR CONVEYOR WITH THE CONVEYOR BELT PROTECTION DEVICE AGAINST THE VOLUME OVERLOAD AND RELEASING SUPPORTING UNIT FOR SUCH A TUBULAR CONVEYOR Russian patent published in 2019 - IPC B65G15/08 B65G43/02 B65G43/08 

FIELD: machine building.

SUBSTANCE: conveyor contains located between the loading (11) and the discharge sections the middle section (13), on which the conveyor belt (15) is rolled into the tubular form under the action of installed on the roller support assemblies the rollers (2). Behind the loading area (11) the measuring supporting unit (5) is located, which includes a stationary frame (53) and capable of turning relative to it the pivoting frame (54). Stationary frame (53) includes mounted under the rolled conveyor belt (15) horizontal transverse axis (h) the lower rollers (22, 24), and the pivoting frame (54) includes mounted over the rolled conveyor belt (15) horizontal transverse axis (h) the upper inclined rollers (23). Conveyor also contains the supporting unit (5), which includes dynamometer (51), enabling the load forces continuous measurement, transmitted from the conveyor belt (15), and characterizing the said load forces signals supply to the control unit (6). Dynamometer (51) contains mounted on the upper roller (21, 23) the weight-sensitive element (52).

EFFECT: enabling the reaction forces from the load measurement during the conveyor belt movement entire period, at that, information on the load forces value is always available.
