The first end that contact KM1-T1 is opened with Dynamic Contact device KM1 is connected, second end of Dynamic Contact device KM1 and the second of control power supply
End is connected.
It is understood that Dynamic Contact device KM1 is connected with the first time delay break contact KM1-T1 electromagnetism.Activate switch is closed
After conjunction, device KM1 is powered for Dynamic Contact, and electric motor of shaker is started working, after continuing the first Preset Time, the first time delay break contact
KM1-T1 disconnects, and Dynamic Contact device KM1 power-off, electric motor of shaker quit work.Therefore this utility model can automatically control rapping electricity
The continuous working period of machine, it is to avoid the too high situation of temperature that electric motor of shaker is caused long lasting for work occurs.
It is shown in Figure 2, the Rapping Motors Control circuit of another kind of bunker wall vibration device that Fig. 2 is provided for this utility model
Electrical block diagram.
Preferably, the circuit also includes locking relay KA1, the second time delay that delay time is the second Preset Time
When break contact KA1-T, locking normally-closed contact KA1-2, the normally opened auxiliary contact KA1-1 of locking and delay time are first default
