The invention relates to mining industry, objects of building industry. At the terminal of belt conveyor that operates at variable length for control of position of the belt at the middle section of the drum a system of automated belt centering is applied. At going from the middle section of the drum the belt affects the deflector rollers that are kinematically connected to the slide valve that at switch on supplies working fluid from oil station to hydro-cylinder that turns the axle of the drum. At turn the drum affects the belt and displaces it to the middle section, so it terminates effect of the belt on deflector rollers. The drive of the oil station of the system of automated centering of the belt is the axle of the tension drum. |
