Outward, clean air is finally siphoned away by aerator and is drained in air, eliminates in air because of the impurity damage to aerator
Bad, extend the service life of aerator, strengthen the stability of absorption；Avoid dust and seed pelleting and aerator
The collision friction of fan blade, noise is low.
The further preferred version of this utility model is: described seeder discharge plate inner chamber passes through the first trachea with described
Annular cavity connects, the negative pressure value in annular cavity described in baroceptor detection.Negative pressure value in annular cavity and broadcasting
The negative pressure value planting machine discharge plate inner chamber is equal, and the negative pressure value in detection annular cavity can obtain the negative pressure of discharge plate inner chamber
Value.
The further preferred version of this utility model is: baroceptor connects has the second trachea, the second trachea to extend into institute
In the annular cavity stated.Air and second trachea of annular cavity are connected, and atmospheric pressure value is identical, thus obtains annular cavity
Negative pressure value.
The further preferred version of this utility model is: also include numeral pneumatic indicator and buzzer, described numeral
Pneumatic indicator is connected with control circuit, and described buzzer is connected with control circuit.If being less than or exceeding certain number
Then control buzzer siren to sound a buzzer.Under the high speed rotating of aerator, dust receives bucket to be internally formed high negative pressure,
Dust receives bucket and the inside of the first trachea being attached thereto also forms negative pressure, and seed is adsorbed at seeder by strong negative-pressure
Above discharge plate, known the true negative pressure of the discharge plate of seeder by the reading on baroceptor digital display screen
Value, user can regulate the rotating speed of aerator to adjust the true negative pressure value within seeder, permissible for different crops
Construct by different negative pressure value.
After user uses a period of time, after the dust that Air Filter Filter Core surface adsorption is abundant, dust storage bucket with
And the negative pressure of the first pipe being attached thereto lowers, seed absorption strength is caused to decline and the generation broadcast leakage that comes off, now
Baroceptor is transferred to control circuit dust storage bucket internal gas pressure data by signal of telecommunication mode, and then reports to the police buzzing
Device provides instruction to carry out the buzzing of high-decibel value and reports to the police, and user hears that audio warning stops cleaning Air Filter Filter Core or more
Ventilate filter core.Negative pressure in display device intuitively, can capture the most flexibly with adjust various the most straight
The crop seeds of footpath size sows required various negative pressure value accurately.
The further preferred version of this utility model is: air filtering assembly includes Air Filter Filter Core and frame of filter element, institute
The frame of filter element stated is positioned at the inner side of Air Filter Filter Core.Frame of filter element supports Air Filter Filter Core, helps air filtration
Filter element keeps out the suction of aerator, makes air filtering assembly more stable.
The further preferred version of this utility model is: described aerator is brush DC centrifugal blower.Brush DC
Centrifugal blower can be directly connected to the storage battery of the 12V of agricultural vehicle by brush DC circuit board, it is not necessary to is started by agricultural vehicle
Machine provides electric energy, also can keep stable air force under idle conditions, it is to avoid give because engine speed is fluctuated
The impact that absorption brings, absorption is stably not easily formed broadcast leakage, and noise is low, and volume is little to be easily installed.
Compared with prior art, the utility model has the advantages that baroceptor is within the seeder discharge plate collected
Negative pressure value passes to control circuit, and control circuit regulates the rotating speed of aerator by the size analyzing negative pressure value, arrives
Discharge plate absorption different size, the required negative pressure of variety classes seed, applied widely；When in seeder discharge plate
During the pressure abnormity in portion, power supply can be closed to detect whether equipment breaks down, prevent broadcast leakage.
