The outfan of described ignition key switch 10 normally opened contact a: road and time-delay relay 15 are connected, is connected with described electromagnetic gas valve 4 after another road series diode I 17. Described ignition key switch 10 has three gears, left gear to be power-off gear, and namely normally opened contact and normally-closed contact are all opened, and are in released state; Intervening gears is operation range, i.e. normally-closed contact Guan Bi, and normally opened contact is opened; Right gear is igniting gear, and normally opened contact and normally-closed contact all close, in an ON state. Fig. 1 show intervening gears state.
Described Vehicular accumulator cell 1 is connected with the normally-closed contact of described two four-ways interlocking button 2 after being connected with the time-delay relay contact 16 of described time-delay relay 15 by electric wire again, and the outfan of the normally-closed contact of described two four-ways interlocking button 2 is by ground connection after the coil of starting relay 3; Normally opened contact one end of described two four-ways interlocking button 2 is connected Vehicular accumulator cell 1 one end and is connected on electromagnetic gas valve 4 by diode III 14.
Described Vehicular accumulator cell 1 is connected by the positive pole of the contact of starting relay 3 with described startup motor 12, the negative pole end ground connection of described startup motor 12.
Described Vehicular accumulator cell 1 is connected with described electronic flame-out device 13 positive terminal by electric wire, the negative pole end ground connection of described electronic flame-out device 13.
Described electromagnetic gas valve 4 is connected with described cylinder 5 by gas circuit; The clutch of the clutch 6 controlled by cylinder 5, the power output pulley 7 connected with clutch 6 is connected with blower fan belt wheel 9 by power output belt 8, described cylinder 5 is additionally provided with the single-way gas-discharge valve making piston rod slowly retract, when the expansion link of electromagnetic gas valve 4 power-off exhaust hood is slowly retracted.
When pavement cleaning starts normal operation, keeping two four-way interlocking buttons 2 is the state of upspringing, as shown in Figure 1, it is open mode that two four-ways interlocking button 2 connects the normally opened contact of electromagnetic gas valve 4, the normally-closed contact connected between starting relay 3 is closure state, now, with key starting ignition key switch 10, ignition key switch 10 is made to be in right gear, namely the normally opened contact of ignition key switch 10 and normally-closed contact are closure state, fuel oil on-off valve 19 is opened, fuel oil is carried to assistant engine, time-delay relay 15, electromagnetic gas valve 4 simultaneously electric (diode I 17 is in the conduction state), the piston rod of cylinder 5 stretches out, clutch 6 is made to disengage, power output pulley 7 can not rotate, after screwing key two seconds, time-delay relay 15 action, time-delay relay contact 16 closes, and starting relay 3 obtains electric, and assistant engine starts motor 12 and must electrically activate, so that assistant engine 11 No Load Start. the adhesive action delay time of this time-delay relay 15 is set as two seconds, and after namely time-delay relay 15 obtains electric two seconds, time-delay relay contact 16 just closes. after assistant engine 11 has started, unclamp key, ignition key switch 10 is made to be placed in intervening gears, the i.e. normally-closed contact Guan Bi of ignition key switch 10, normally opened contact disconnects, as shown in Figure 1, now electromagnetic gas valve 4, time-delay relay 15 dead electricity, time-delay relay contact 16 disconnects, the piston rod of cylinder 5 is slowly retracted under the effect of single-way gas-discharge valve, clutch 6 is made slowly to engage, power output pulley 7 is driven to rotate, and impart power to blower fan belt wheel 9 by power transmission belt 8, thus driving blower fan to rotate, realize the band load non-impacting start of assistant engine 11.
During engine misses, closing ignition key switch 10 so that it is be placed in left side gear, namely the normally opened contact of ignition key switch 10 and normally-closed contact all disconnect, and now, fuel oil on-off valve 19 is closed, and assistant engine stops working because interrupting fuel oil conveying; The IN end dead electricity of electronic flame-out device 13 simultaneously. After electronic flame-out device 13 power-off, the output end signal time delay of electronic flame-out device 13 was closed after 1 minute. Now; the OUT terminal of electronic flame-out device 13 has output in one minute; namely electromagnetic gas valve 4 obtains electric one minute; the piston rod of cylinder 5 stretches out and makes clutch 6 disengage; assistant engine 11 and blower fan freely stop by rotator inertia; electromagnetic gas valve 4 power-off after one minute, the piston rod of cylinder 5 is slowly retracted, and is achieved in that the non-loaded shutdown of assistant engine.
The occasion of blower fan operating is not needed dump rubbish, traffic congestion etc., press two four-way interlocking buttons 2, making its normally-closed contact open, normally opened contact closes, and namely cuts off while assistant engine starting relay 3 ignition circuit, electromagnetic gas valve 4 is connected by diode III 14, electromagnetic gas valve 4 energized action, connects the gas circuit of cylinder 5, so that the piston rod of cylinder 5 stretches out, open clutch 6, so that blower fan shuts down. Restart blower fan, then perform contrary operation, again press two four-way interlocking buttons 2.
When power belt conveyor 8 changed by needs, two four-way interlocking buttons 2 are pressed under the flame-out stopped status of assistant engine, connect electromagnetic gas valve 4, i.e. electromagnetic gas valve 4 energized action under assistant engine 11 stopped status, connects the gas circuit of institute's cylinder 5, so that the piston rod of cylinder 5 stretches out, open clutch 6, making power output pulley 7 freely rotatable, conveniently dismounting and installation power belt conveyor 8, improve work efficiency; Cut off the ignition circuit of assistant engine starting relay 3 simultaneously, stopped the hidden danger that maloperation ignition key switch 10 makes assistant engine 11 start, ensure the safety of maintainer.
