[utility model content]
The technical problems to be solved in the utility model is to provide a kind of boiler mucking machine full-automatic control circuit, and it can realize automation control, reduces electric energy loss, equipment loss, cost of labor.
The utility model is achieved in that a kind of boiler mucking machine full-automatic control circuit, comprise the positive contactor coil of mucking machine KM1, mucking machine counter-rotating contactor coil KM2, electrothermal relay, the anodal end of described electrothermal relay connects live wire, negative pole one end is connected to the counter-rotating start button by stop button, just changeing start button, described counter-rotating start button is by the KM1 normally-closed contact, KM2 is connected to zero line, it also comprises auxiliary reclay KA1, auxiliary reclay KA2, time relay KT1, time relay KT2, described KA1 negative pole one end connects zero line, an anodal end is connected to by the KM2 normally-closed contact and just changes start button, described KM2 normally-closed contact also is connected to stop button by KA1 normally opened contact three, one end of the normally opened contact one of described KA1 connects live wire, the other end connects the normally-closed contact one of KA2 respectively, the normally opened contact of KT1 and the normally opened contact of KA2, described KA2 normally-closed contact one is connected to zero line by KT1, the other end of described KT1 normally opened contact and KA2 normally opened contact is connected respectively to KT2 and KA2 by the KT2 normally-closed contact, negative pole one end of described KT2 and KA2 is connected to zero line, the anodal end of described KM1 is by KA1 normally opened contact two, KA2 normally-closed contact two is connected to live wire, and negative pole one end is connected to zero line.
Advantage of the present utility model is:
Mucking machine is under the effect of auxiliary reclay one, auxiliary reclay two, the time relay one, the time relay two, make the start-stop of mucking machine, just change operation and can realize automatic operation, no longer need manually-operated, significantly reduce mucking machine idle running chance, reduced the electric energy loss of mucking machine, equipment loss, and reduced artificial cost.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the direct start-up control circuit of existing mucking machine.
Fig. 2 is an electrical block diagram of the present utility model.
[specific embodiment]
See also shown in Figure 2ly, embodiment of the present utility model is described in detail.
As Fig. 2, the utility model increases auxiliary reclay 1 (following abbreviation KA1), auxiliary reclay 22 (following abbreviation KA2), the time relay 1 (following abbreviation KT1), the time relay 24 (following abbreviation KT2) on the basis of existing technology.As Fig. 2, the utility model comprises auxiliary reclay KA1, auxiliary reclay KA2, time relay KT1, time relay KT2, the positive contactor coil 5 of mucking machine (following abbreviation KM1), mucking machine counter-rotating contactor coil 6 (following abbreviation KM2).Described electrothermal relay 7 anodal ends connect live wire, negative pole one end is connected to counter-rotating start button 9, just changes start button 10, KA1 normally opened contact 3 13 by stop button 8, described counter-rotating start button 9 is connected to zero line by KM1 normally-closed contact 61, KM2, and the described other end that is just changeing start button 10, KA1 normally opened contact 3 13 is connected to zero line by KM2 normally-closed contact 51, KA1.Normally opened contact one 11 one ends of described auxiliary reclay KA1 connect live wire, the other end connects the normally-closed contact 1 of KA2, the normally opened contact 31 of KT1 and the normally opened contact 23 of KA2 respectively, described KA2 normally-closed contact 1 is connected to zero line by KT1, the other end of described KT1 normally opened contact 31 and KA2 normally opened contact 23 is connected respectively to KT2 and KA2 by KT2 normally-closed contact 41, negative pole one end of described KT2 and KA2 is connected to zero line, the anodal end of described KM1 is connected to live wire by KA1 normally opened contact 2 12, KA2 normally-closed contact 2 22, and negative pole one end is connected to zero line.
