The amount of broadcasting sowing is changed to different needs, but the precise control amount of broadcasting sowing cannot be accomplished, reduced and waste, save seed and fertilizer into
This, and empty van alarm.Such as when operation, general knob position can only be estimated, estimate that discharge velocity control is broadcasted sowing
Value；And, when tractor speed change, when reversing, discharge velocity cannot make corresponding according to the travel speed of tractor
Change, the amount of sowing remained in unit area is constant.In addition, during operation, hopper is at driver rear, and driver is past
Feed toward can not in time find that empty van is shut down.
For problem described above, the current equipment that broadcasts sowing much is unable to reach efficient, accurate, saving, reading intelligent agriculture
The demand of sowing, in the urgent need to a kind of energy follow-up adjustment application rate of exploitation, the seed broadcaster of empty van automatic alarm intelligently controls system.
The content of the invention
The problem to be solved in the present invention cannot be precisely broadcasted sowing to solve existing seed broadcaster, and automatic variable is broadcasted sowing and moveed backward
Break, a series of problems, such as empty van is reported to the police, there is provided it is a kind of can be according to the travel speed of tractor, automatic control motor turns
Speed, so as to keep the amount of broadcasting sowing in unit area constant, and the energy intelligence that automatically empty van is reported to the police broadcasts sowing control system.
To solve above-mentioned technical problem, the technical solution used in the present invention is：A kind of intelligence broadcasts sowing control system, including control
Case processed, it is characterised in that：Radiator is installed in control cabinet touch-screen installed above, operating key, the control cabinet side, described
Operating key is power button, start button, pause button, stops key；
PLC is installed, described PLC one end connects respectively start button, pause button, stopping in the control cabinet
Button, sensor 1, sensor 2；The PLC other end is respectively connected to contactor, touch-screen, driver, buzzer,
The contactor accesses high pressure positive blower, and the driver accesses stepper motor, and the PLC accesses stepup transformer and is connected to electricity
Source button, the sensor 1 is arranged on hopper, and the sensor 2 is arranged on seed broadcaster and seed broadcaster land wheel.
The control system, its contactor is connected to coupling terminal block, connect on the coupling terminal block be respectively connected to it is multiple high
Pressure fan.
The control system, its sensor 1, sensor 2 can be respectively groove type photoelectric switch 1, groove type photoelectric switch 2.
The present invention has the advantages and positive effects that：
1st, seed broadcaster intelligence control system of the present invention is provided with sensor in hopper, when sensor detects hopper without material, Jing PLC controls
Device processed, automatic alarm prompting, and be automatically stopped and broadcast sowing, Based Intelligent Control is realized, eliminate invalid operation.
2nd, the PLC that present invention intelligence broadcasts sowing control system is programming Control system, according on seed broadcaster and land wheel
The sensor of setting detects signal of the tractor in reversing, automatic pause stepper motor and blower fan, stops discharge, prevents down
The repetition that car is caused is sowed, energy saving, reduces fertilizer or seed costs input.
3rd, it is programming Control system that present invention intelligence broadcasts sowing control system Jing PLC, can be detected by sensor
Tractor running signal simultaneously calculates travel speed, and the discharge velocity of automatic accurate adjustment stepper motor is maintained at different travelings
The amount of sowing under speed in unit area is constant, substantially increases the uniformity sowed, and improves the utilization rate of seed or fertilizer,
Reduce fertilizer or seed costs input.
4th, present invention intelligence broadcasts sowing control system Jing PLC, can easily change according to the different demands of different fields
Become the amount of broadcasting sowing, it is only necessary to corresponding numerical value is input in HMI man-machine interfaces, it is easy to adjust flexible, save farming season.

Specific embodiment
In order to be better understood from the present invention, the present invention is further retouched with reference to specific embodiments and the drawings
State.
As shown in Figure 1, 2, the present invention provides a kind of intelligence and broadcasts sowing controller, by control cabinet, touch-screen, power button, opens
Dynamic button, pause button, stop key, stepup transformer, radiator fan, PLC, binding post, wiring groove, sensor, honeybee
Ring device, contactor, high pressure positive blower, driver, stepper motor etc. are constituted.
The touch-screen 1 installed above of control cabinet 2 and operating key, operating key is respectively power button 4, start button 5, time-out and presses
Key 6, stop key 7, the side of control cabinet 2 is provided with radiator 3, and radiator 3 can be that PLC is installed in radiator fan, control cabinet 2
