(2) operating current that detects motor by processor detects the tension force of backguy, need not position transducer and position limit switch; When the Electric Machine Control backguy reached the limit of the position, the electric current of motor was also big 2 ~ 3 times than the electric current of proper functioning, and this moment, control circuit cut off the power supply of motor automatically;
(3) when chain is in relaxation state, controlled machinery still can carry out manually-operable, does not influence tractor and crosses the occasion use that ridge, descending etc. need manually control;
(4) speed reducer is band worm screw self locking type, thus when the control motor stops operating, the worm gear braking, thus sprocket wheel is braked.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the internal control circuit theory diagram of the utility model electric control box.
Among the figure: electric control box 1, upper-position unit 1a, processor 1b, motor-drive circuit 1c, direct current generator 2, reducing gear 3, sprocket wheel 4, chain 5, latch 6, clamping plate 7, machinery control backguy 8.
Embodiment
Consult Fig. 1, shown in Figure 2, a kind of backguy electric controller that adopts sprocket wheel of the present utility model, comprise electric control box 1, direct current generator 2, reducing gear 3, sprocket wheel 4 and chain 5, electric control box 1 is connected with direct current generator 2 circuit, the clutch end of direct current generator 2 is connected with the power intake of reducing gear 3, the clutch end of reducing gear 3 is connected with sprocket wheel 4, and chain 5 one ends are fixedlyed connected with sprocket wheel 4 by latch 6, and chain 5 the other ends are fixedlyed connected with machinery control backguy 8 by clamping plate 7.Be provided with upper-position unit 1a, the processor 1b and the motor-drive circuit 1c that connect in regular turn in the electric control box 1; Upper-position unit 1a sends instruction, and treated device 1b handles the back and controls direct current generator 2 by motor-drive circuit 1c; The size that processor 1b detects direct current generator 2 feedback currents judges whether backguy strains and moves the position to, and electric current was less when direct current generator 2 ran well, and load became big and electrorheological is big when direct current generator 2 backguys put in place, need not additional sensor; Processor 1b reacts according to detecting size of current, thereby determines the action of direct current generator 2; Reducing gear 3 is the speed reducer of band worm screw auto-lock function.
When the utility model is used for the control of dilatory machine automatic drive, send command signal by upper-position unit 1a after, be transferred to processor 1b immediately and handle, make corresponding action by motor-drive circuit 1c control direct current generator 2 then, specifically be achieved in that
A. the control motor M 1 (control left steering) of turning left and the control motor M 2(control right steering of turning right):
M1 was to counterclockwise rotating when 1, upper-position unit 1a sent " left-hand rotation " command signal, slow down the back by the 5 pulling tractor left steerings machinery control backguys 8 of sprocket wheel 4 drive chains by reducing gear 3, the M1 load becomes big when moving to, the detection electrorheological is big, processor 1b sends instruction, and M1 is stopped operating.Because reducing gear 3 is band worm screw self locking type, thus when M1 stops operating, the worm gear braking, the left-hand rotation guide line is strained can not playback, thereby the tractor revolver is run out of steam.If the last instruction that upper-position unit sends is " right-hand rotation ", then M1 is when counterclockwise rotating, and M2 clockwise rotates certain hour, and tractor right steering machinery control backguy 8 is playbacked under the effect of inner return spring.When M2 is non-loaded, detect electric current and keep normal, the M2 time-delay stops, thus right wheel does not run out of steam, and still can normal rotation.Because tractor wheel frictional force over the ground when farming is very big, so the revolver that runs out of steam can stop operating tractor left steering at this moment.
M2 was to counterclockwise rotating when 2, upper-position unit sent " right-hand rotation " command signal, pulling tractor right steering machinery control backguy 8, and the M2 load becomes big when moving to, and it is big to detect electrorheological, and processor 1b sends instruction, and M2 is stopped operating.Because reducing gear 3 is band worm screw self locking type, so when M2 stopped operating, the worm gear braking can not be playbacked the tension of right-hand rotation guide line, thereby right wheel of tractor run out of steam.If the last instruction that upper-position unit 1a sends is " left-hand rotation ", then M2 is when counterclockwise rotating, and M1 needs to change clockwise certain hour, and tractor left steering machinery control backguy 8 is playbacked under the effect of inner return spring.When M1 is non-loaded, detect electric current and keep normal, the M1 time-delay stops, thus revolver does not run out of steam, and still can normal rotation.Because tractor wheel frictional force over the ground when farming is very big, so the right side wheel that runs out of steam can stop tractor right steering at this moment.
When 3, upper-position unit sends " advancing " command signal, processor 1b has write down a last instruction: if a last instruction is for rotating to certain direction, the motor that then should control this direction needs to change clockwise certain hour, make this steering mechanical control backguy 8 of tractor be in relaxation state, the control backguy 8 of this direction is playbacked under the effect of the inner return spring of machinery, when this motor is non-loaded, detect electric current and keep normal, this motor time-delay stops.If a last instruction is " stopping ", then two motors all need to change certain hour clockwise, and mechanical guide line playbacks under the effect of inner return spring, make the steering mechanical control backguy 8 of the tractor left and right sides be in relaxation state simultaneously.The event left and right wheels is all rotated, at this moment the tractor straight line motion.
When 4, upper-position unit sends " stopping " command signal, processor 1b has write down a last instruction: if a last instruction is for rotating to certain direction, then this directional steering machinery guide line is in tension, the motor that processor 1b controls other direction changes certain hour counterclockwise, make tractor left and right sides steering mechanical guide line be in tension, when this motor was moved to, it was big to detect electrorheological, and this motor stops operating.Because reducing gear 3 is band worm screw self locking type, so when motor stopped operating, the worm gear braking made two to turn to guide line to strain can not to playback, thereby the tractor left and right wheels is run out of steam.Because tractor wheel frictional force over the ground when farming is very big, so the left and right wheels that runs out of steam can stop tractor stop motion this moment.
B. the clutch motor M 3:
When 1, upper-position unit 1a sent " clutch " command signal, M3 was to counterclockwise rotating, pulling clutch machinery guide line, and the M3 load becomes big when moving to, and it is big to detect electrorheological, and processor 1b sends instruction, and M3 is stopped operating.Because reducing gear 3 is band worm screw self locking type, thus when M3 stops operating, the worm gear braking, the clutch for clutch control line is strained can not playback, thereby makes tractor be in clutch state.
When 2, upper-position unit sent " joint " command signal, M3 rotated to clockwise direction, loosened clutch machinery guide line, guide line playbacks under the effect of the inner return spring of machinery, realizes bonding operation, when this motor is non-loaded, detect electric current and keep normal, this motor time-delay stops.
