The timing of the electrified time delay relay KT1 is started, the KM coil is electrified to enable the normally open main contact KM-2 to be connected with a motor wire, the motor runs, and the speed reducer drives the stirring blade 4 to run and stir mortar. Meanwhile, the normally open auxiliary contact KM-1 is switched on, and the motor operation indicator lamp HL is lightened. The normally closed contact KA1-4 is opened to cut off the circuit of the electrified delay relay KT2, namely, a coil of KT2 cannot be electrified, so that the two electrified delay relays are interlocked. When the motor runs for a preset time, namely the timing of the electrified delay relay KT1 is completed, the normally closed contact KT1-1 is opened, the normally open contact KT1-2 is closed, namely the relay KA1 loop is in series connection with the normally closed contact KT1 to enable the KA1 coil to lose power, the contact of the relay is reset, the normally closed contact KA1-4 is closed, and the normally open contact KA1-1 is opened to the normally open contact KA 1-4. When the KM coil loses power, the normally-open auxiliary contact KM-1 and the normally-open main contact KM-2 are disconnected, a motor circuit and a motor operation indicator lamp HL are cut off, the motor stops operating, meanwhile, the KA2 coil is electrified, and the normally-open contact KA2-1 and the normally-open contact KA2-2 are closed. The coil KA2 realizes self-locking, keeps always electrified, a normally open contact KA2-2 is closed to switch on the coil KT2, and the electrified time delay relay KT2 starts to time.
