Be applicable to automatic adjusting device of mine production vibratory feeder vibration frequency

The utility model discloses a be applicable to automatic adjusting device of mine production vibratory feeder vibration frequency, solved exist among the prior art carry out second -time breakage intensity of labour is big, equipment wear is serious problem to the raw ore, including setting up the current transformer on the power supply wire of breaker, current transformer still in proper order with the thyristor circuit board, contactor and circuit breaker are connected, the thyristor circuit board still is connected with the vibrator, the circuit breaker is supplied power by power A, currenttransformer detects the real -time electric current of breaker, to detect numerical value through with the parameter in the threshold value relatively, if real -time electric current is greater thanthe threshold value, satisfy adjustment condition control external circuit, the electric current that the messenger inputed vibratory feeder reduces, reduce the material effect that gets into the breaker in order to reach the
