The difference asking (gram/acre) corresponding broadcasts coefficient of discharge, is stored in detection feedback controller 13.
In described step 003, motor 15 Duty ratio control algorithm is: dutycycle=broadcast coefficient of discharge × pulse signal frequency.
In the present embodiment, seeding operation object is Semen Brassicae campestris, and seeder operation railway carriage or compartment face width is 2 meters, sowing line number is 6
OK, the agriculture requirement mu amount of broadcasting in the range of 250-450 gram, tiller operation theory pace 35 meter per second (2.1 kms/little
Time), the mu theoretical pure seeding operation time is about 9.53 minutes, a diameter of 0.5 meter of road wheel, uniform magnet steel 24 on tachometer disk 9
Quantity is 16, and seeder pace detection pulse signal theory arteries and veins frequency is 356.5 beats/min, and motor 15 is 12V, 150W
Direct current generator (rain field motor, 5D150-12), decelerator 25 speed reducing ratio is 10, use rain field motor 5GU10K, drive rotating speed
Scope is 0-330 rev/min；The Brassica campestris L flow rate of centrifugal feed 14 and the right of motor dutycycle is determined by bench test
Should be related to as shown in Figure 4, require and flow rate and motor dutycycle corresponding relation according to the rapeseed cultivation mu amount of broadcasting, choose dutycycle
In 0.10-0.40, flow rate q at 14-58 gram/minute range intervals, opening relationships function, for linear relationship: p=0.0069q+
0.0058, the linear fit coefficient of determination is 0.9976, and its inverse function, i.e. flow rate be: q=144.81p-0.7621.
The Duty ratio control algorithm of motor 15 is: dutycycle=broadcast coefficient of discharge × pulse signal frequency, it is achieved that feed mechanism for seed
Working speed associates control with seeder pace.
When application rate requirement is 250 grams/acre, feed mechanism for seed ideal flow rate should be 26.23 grams, according to dutycycle and seeding
Flow function relation, determines that feed mechanism for seed dutycycle should be 0.1868, and seeder pace detection pulse signal theory arteries and veins frequency is
356.5 beats/min, then broadcasting coefficient of discharge is k=2407 × 10-4.In like manner can determine that application rate requires as 250g-450 gram/acre of scope
The application rate that interior a certain numerical value is corresponding, as the amount of broadcasting requires 260 grams/acre, broadcasting coefficient of discharge is 5.4438 × 10-4；Application rate requirement
270 grams/acre, broadcasting coefficient of discharge is 5.6469 × 10-4... should the amount of broadcasting store above-mentioned in the controller with broadcasting coefficient of discharge.
Before seeding operation starts, seed is loaded in centrifugal feed 14, set on the controller according to agriculture requirement
Good application rate, controller calls corresponding broadcasts coefficient of discharge；The diesel engine 11 that electrically activates of power unit exports power, drives row
Travelling wheel 7, makes seeder advance, charges for accumulator 12 simultaneously, it is ensured that the electric power of accumulator 12 is sufficient；Motor 15 drives centrifugal
Feed mechanism for seed 14, makes seed be discharged by mouth 16 of charging seed under the influence of centrifugal force, at gravity and inertia after part flow arrangement shunts
Moved in the kind ditch that the double-arc spline in plough covering device is outputed by grain conductor 18 under the effect of power, the coverer pair at rear
Seed carries out earthing and completes sowing.
In operation process, when seeder pace is theoretical velocity, dutycycle be call broadcast coefficient of discharge × theory
Umber of pulse, is theoretical dutycycle, and feed mechanism for seed rotating speed is constant, and flow rate is constant, and the pure seeding operation time is constant, and application rate is for wanting
Seek application rate；When seeder operating speed is accelerated, driving wheel faster rotational speed, velocity measuring dish rotates and synchronizes to increase, seeder
Pace detection pulse signal frequency is accelerated, and feed mechanism for seed drives motor dutycycle to increase, rotating speed increases, and feed mechanism for seed rotating speed increases
Adding, unit interval flow rate increases, but unit interval travel distance rises, and application rate still keeps constant；Otherwise when seeder is made
When industry speed declines, flow rate reduces, but unit interval travel distance declines, and flow rate remains in that constant, it is achieved that seeding
Amount is associated with seeder pace, the sowing of the high-quality of application rate precise control.
Being 430 grams/acre with application rate to be analyzed, it broadcasts coefficient of discharge is 8.8969 × 10-4, seeder is with different work speed
When degree advances, theoretical mu application rate and the bench test mu amount of broadcasting as schematically shown in Figure 5, from result of calculation in figure, work as seeder
When operating speed changes in the range of 1.88-2.83 is thousand ms/h, theoretical mu sowing change, within 1%, utilizes feed mechanism for seed to try
Testing platform simulation field test, the actual mu amount of broadcasting changes within 5%, shows that the method achieving flow rate advances fast with seeder
Degree is associated, the sowing of the high-quality of application rate precise control.
