Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention mainly comprises arm-rest frame 1, hand from stopping handle 2, starting panel 3, gear level 4, accumulator 5, diesel powered assembly 6, gear block 7, road wheel 8, resistance rod 9, travel switch 10, chassis 11, transmission assembly 12,
Chassis 11 is fixed diesel powered assembly 6 and transmission assembly 12, diesel powered assembly 6 clutch end connects transmission assembly 12, the walking axle bottom transmission assembly 12 output connecting base plate 11, and walking axle two ends connect a road wheel 8 respectively.Rear end, chassis 11 is provided with resistance rod 9.
Transmission assembly 12 connects arm-rest frame 1, arm-rest frame 1 is provided with hand from stopping handle 2 and starting panel 3.Transmission assembly 12 top is provided with accumulator 5, transmission assembly 12 connects gear block 7, gear block 7 connects gear level 4.Transmission assembly 12 is provided with travel switch 10.
As shown in Figure 2, accumulator 5 one end stops holding with the normally-closed contact of firing switch 13 and is electrically connected, and the stopping end of firing switch 13 is held with operation and is communicated with.Accumulator 5 other end is electrically connected with travel switch 10, and travel switch 10 other end is electrically connected with neutral pilot lamp 14 one end, and neutral pilot lamp 14 other end is electrically connected with the operation end of firing switch 13.
Be electrically connected the coil of relay 15 between the operation end of firing switch 13 and travel switch 10 one end, the two ends, contact of relay 15 connect starting end and the actuating motor 16 of firing switch 13 respectively.Because the electric current amount of bearing of travel switch 10 is less, in electric wiring, connect a high-current relay 15, can play a protective role to electric wiring and other electrical equipments, to ensure the functional reliability of each electrical equipment.
When gear block 7 is positioned at neutral gear position A, gear block 7 presses down travel switch 10 contact, and travel switch 10 place circuit ON, neutral pilot lamp 14 lights.The coil electricity of the relay 15 in parallel with neutral pilot lamp 14 make relay 15 closing of contact switch starting 13 starting end and actuating motor 16.Rotate firing switch 13, the stopping end of firing switch 13 is communicated with starting end, and now electric motor 16 place circuit is communicated with accumulator 5, and actuating motor electromagnetic switch 17 closes, and actuating motor 16 works.When gear block 7 be positioned at a gear put B or two gears put C time, gear block 7 departs from travel switch 10 contact, travel switch 10 place circuit disconnects, actuating motor electromagnetic switch 17 disconnects, neutral pilot lamp 14 does not light, during rotation firing switch 13 to start position, actuating motor 16 cannot switch on power, and user cannot start diesel powered.
Operation principle of the present invention is: user is when operating mini-size tillage machine, as long as by operation gear level 1-4, shift block 1-7 is placed in neutral gear position, makes the contact of shift block 1-7 depression stroke switch 1-10 arrive A point position, trigger relay 2-3 is closed to switch on power, now, neutral pilot lamp 2-2 on the right of firing switch lights, and represents whole electric wiring and switches on power, and rotates firing switch 2-1 to start position, actuating motor 2-4 is switched on power, can normal starting diesel powered.
And when operate gear level 1-4 push ahead into advance one grade or pull back enter advance two file location time, because shift block 7 leaves the contact of travel switch 10, the contact of travel switch 10 is ejected to B electric position, relay 13 is in off-state, now, a dress electric wiring is in off-position, and the neutral pilot lamp on the right of firing switch does not light, rotate firing switch cannot switch on power to actuating motor during start position, user cannot start diesel powered.Because the electric current amount of bearing of travel switch 10 is less, a high-current relay 13 of connecting in electric wiring, can play a protective role to electric wiring and other electrical equipments, to ensure the functional reliability of each electrical equipment.Like this, due to this kind of starting safety and firing mechanism linked with starting device, in whole starting process, the walking of mini-size tillage machine and workpiece, can not oriented before walking or rotation work situation occur, thus avoid the unexpected injury that may cause to user, improve the security performance of mini-size tillage machine operation.
User is when operating mini-size tillage machine, as long as by operation gear level, shift block is placed in neutral gear position, the fast depression stroke switch of gearshift is made to enter on-state, thus trigger relay switches on power, now, the neutral pilot lamp on the right of firing switch lights, represent whole electric wiring to switch on power, rotating firing switch can normal starting diesel powered to start position.And when operate gear level push ahead into advance one grade or pull back enter advance two file location time, because shift block leaves travel switch, travel switch is upspring and is in off-state, now, a dress electric wiring is in off-position, neutral pilot lamp on the right of firing switch does not light, and rotates firing switch and cannot start diesel powered to during start position.Like this, in whole starting process, the walking of mini-size tillage machine and workpiece, can not oriented before the situation of walking or rotation work occur, thus avoid the unexpected injury that may cause to user, improve the security performance of mini-size tillage machine operation.
