METHOD TO ADJUST SPEED OF CONVEYOR WITH LOADING HOPPER Russian patent published in 2017 - IPC B65G43/08 

FIELD: machine engineering.

SUBSTANCE: hopper is loaded regardless of feeder and conveyor operation, if fill level ψ of the hopper does not exceed the hopper fill level limit ψ_n. The conveyor and the feeder are switched on by command of the control system (CS), if hopper filling level ψ exceeds initial hopper filling level ψ₀, then the feeder efficiency W and the conveyor belt speed V are synchronously changed to W_i and V_i, if the hopper filling level ψ corresponds to the condition ψ_i-1<ψ≤ψ_i, and V≠V_i and W≠W_i, i=1…n, where n is the number of speed control stages, ψ_i - value of the i-th level of the hopper filling, V_i - value of the i-th stage of the belt speed, W_i - value of the i-th stage of the feeder efficiency; or provide feeder efficiency W=W_n and the conveyor belt speed V=V_n, if ψ>ψ_n. The feeder is turnred off, and then after removing the load from the belt the conveyor is stopped if the hopper filling level ψ is less than the initial hopper filling level ψ₀ value, or the belt speed V and/or feeder efficiency W do not take the value V_i and W_i during the adjustment time, or the control system has issued a command to stop the conveyor.

EFFECT: increases efficiency of the conveyor with the loading hopper.
