Cross the solution inflow hole that perforation is provided on 31 end face of the first fast pulley；It reaches between the first fast pulley 31 and the second fast pulley 49；
While urea flows into the pump housing 2, power distribution cabinet 1 at this time will act on stator winding 16, so that rotor assembly 17 will
It will drive installation set 23 to make rotating motion, installation set 23 will will drive fixed cylinder 19 and make rotating motion, and fixed cylinder 19 will will drive
4th fixing axle 40 movement mounted thereto, the 4th fixing axle 40, which will will drive the 4th bevel gear 39 mounted thereto and do, revolves
Transhipment is dynamic, since the installation site of the soft blade 48 in urea dispenser pump at this time has regulated, so servo electricity at this time
Machine 5 will not move, so that the first fixing axle 22 will not move, the first fixing axle 22 will not drive the 5th bevel gear
38 make rotating motion；Electric machine 10 at this time will will drive 19 rotary motion of fixed cylinder simultaneously, by the 4th bevel gear 39, the
Third hand tap gear 37, second bevel gear 34 move, second bevel gear 34, first bevel gear 33, the 6th bevel gear 42, the 7th bevel gear
43 transmission effect, adjustment gear 30 at this time only can will follow fixed cylinder 19 to make rotating motion, without the axis around itself
Line rotation；So adjustment gear 30 at this time and adjusting opposing stationary between gear ring 20；The fixed cylinder 19 moved in this process
Fixed disc 32 will be will drive to move, fixed disc 32, which will will drive the second fast pulley 49 mounted thereto and do, to be rotated；Second
Fast pulley 49 is moved will drive arc-shaped guide rail 50 mounted thereto, keeps opposite between adjustment gear 30 and adjusting gear ring 20

It is static；The adjusting gear ring 20 moved at this time is moved will drive fixation arc block 47 mounted thereto, and fixed arc block 47 will band
It moves soft blade 48 mounted thereto to move, soft blade 48 will be forced between the first fast pulley 31 and the second fast pulley 49
Urea quickly flow, urea hereafter will be external by the liquid outlet channel efflux pump opened on the pump housing.
When the installation site for needing to adjust soft blade in urea dispenser pump, come when adjusting urea flowing velocity, matching at this time
Electric cabinet 1 will power to servo motor 5；Servo motor 5 will rotate, and the servo motor 5 of movement will will drive the 5th bevel gear
38 movements, in the 5th bevel gear 38, the 4th bevel gear 39, third hand tap gear 37, second bevel gear 34, first bevel gear 33, the
Under six bevel gears 42,43 transmitting of the 7th bevel gear effect, while the movement on electric machine 10 will also pass through the 5th bevel gear
38, the 4th bevel gear 39, third hand tap gear 37, second bevel gear 34, first bevel gear 33, the 6th bevel gear the 42, the 7th bore tooth
43 transmitting effect is taken turns, adjustment gear 30 is moved around own axes under the collective effect of electric machine 10 and servo motor 5；This
When adjustment gear 30 will drive and adjust gear ring 20 and move occur between gear ring 20 and the second fast pulley 49 so that adjusting
Relative rotary motion, so that the fixation arc block 47 being mounted on the second fast pulley 49 will will drive soft blade 48 and the second fast pulley
49 occur relative motion, will be swung by the arc-shaped guide rail 50 that straight pin 51 is mounted on the second fast pulley 49 at this time certain
Angle will adapt to the rotary motion for adjusting gear ring 20 under the soft effect of guide groove 53 and soft blade 48 on arc-shaped guide rail 50,
The installation site between soft blade 48 at this time will change, and the changed soft blade 48 of installation site will push
Urea speed between first fast pulley 31 and the second fast pulley 49 changes, and reaches and adjusts urea dispenser pump to urea promotion
The purpose of speed；As shown in figure 11, it will be flowed out between the first fast pulley 31 and the second fast pulley 49 by the urea of acceleration,
The rotation speed of impeller 8 during this can be adjusted by electric machine 10, will make urea dispenser pump driving urine in this way
The speed of element flowing is adjusted, while will make 48 installation site of soft blade in impeller 8 by the adjusting of servo motor 5
It changes, so that soft blade 48 drives the speed of urea flowing to be adjusted again, by electric machine 10 and servo
The collective effect of motor 5 will make the urea dispenser pump in the present invention opposite with traditional urea dispenser pump in driving flow of urea
It is more accurate on dynamic speed control.
In conclusion it is restricted embodiment of the invention, all those skilled in the art that above embodiment, which is not,
On the basis of substantive content of the invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as this
The protection scope of invention.
