555 belt feeder integrated protector circuit
Pressing the starting button QA, 12V voltage is added to IC1, IC2, J1 pulls in, the starting ring makes a sound. Once it is added +12V, IC1 is set, when C1 is charged to 2/3 VDD by R1, IC1 is reset. C1's charge time also is the starting delay time td=1.1R1C1, it is about 5s. T probe in the virtual frame is coal position sensing probe, when the conveyor belt's coal position height touches T probe, it is equal that a no more than 3.2MΩ resistor is between 555's 2 foot and ground , 2 foot's level is lower than 1/3VDD, then IC1 is set, J2 is released, J2-1 is disconnected from the starter, motro M stops running, the electric bell alarms.
