Background technology
At present, with the fast development of science and technology, in the operation of land for growing field crops, big-and-middle-sized mechanization of agriculture dispenser equipment will become
For main flow working equipment.As wind curtain type spray bar type spraying machine has, spraying swath is big, working performance is high, spray effect good, environment is dirty
The features such as dye is few, starts to promote on part farm and uses.The air curtain air bag of wind curtain type boom sprayer is erect by one and is justified
Post air bag and two ends are symmetrical, the orthogonal composition of the circular cone shape air bag of horizontal positioned, and air curtain air bag bottom center is provided with ground
The aperture in face, using the air curtain of aperture blowout, aids in droplet to crop canopies, to reduce float of mist droplet.Air-flow reaches crop
Wind speed profile during top has a significant impact to spraying distribution uniformity, droplet uniformity.If wind speed is too little, air-flow is difficult to
Stir branch and leaf, it is impossible to plant is penetrated, if wind speed is too big, air-flow can penetrate plant, and colliding surface simultaneously rebounds, so as to take away droplet.
The cylinder air bag of existing wind curtain type boom sprayer wants little several times with respect to double cone mesa-shaped air bag, and diffuser is shorter, air-flow
From after the outflow of cylindric air bag, most of air-flow is flowed out so as to cause medial small hole flow velocity relatively fast and two ends from medial small hole
Aperture flow velocity is relatively slow, and this greatly reduces the effect of spraying.It is thus desirable to improve from air curtain spraying the wind speed of air-flow in horizontal stroke
Uniformity upwards.
Chinese patent CN101607236A provides a kind of pulverizer wind cone with flow-guiding structure, changes air-flow stream
To making which reach air curtain two ends, but the Wind cylinder structure is it cannot be guaranteed that air curtain interior air-flow speed is in horizontal uniformity.

Further, the non-homogeneous deflector is connect with air curtain airbags by sewing thread.
Further, the air inlet end of the air curtain air bag is fixed by sealing gasket, gland and bolt and nut and air duct and is connected
Logical.
The design philosophy of the present invention is to improve air-flow uniformity in the horizontal using non-homogeneous deflector, while using bend pipe
Air-flow being imported to air curtain both sides increases both sides air quantity, improves uniformity of the air-flow in cross direction profiles further.Multiple non-homogeneous lead
Circular cone shape air bag is separated into several parts by stream plate, and air enters circular cone shape air bag after axial flow blower acceleration, through multiple
Non-homogeneous deflector gradually improves air-flow uniformity in the horizontal, while importing gas using bend pipe to circular cone shape air bag both sides
Stream increases both sides air quantity, improves air-flow further in cross direction profiles uniformity.Uniform air flow reach air-out hole site, most after through going out
Air holes sprays, and is being transversely formed uniform air curtain.
The blast system of the present invention can apply to wind curtain type boom sprayer, and also apply be applicable to other needs uniform air curtain
Occasion.Beneficial effects of the present invention：A kind of blast system of wind curtain type boom sprayer of the present invention, based on multiple non-homogeneous
Deflector and bend pipe flow-guiding structure make air-flow uniformly reach air-out hole site, form uniform air curtain.It is equal that the blast system is formed
Even air curtain can effectively improve the uniformity of mist droplet deposition, reduce float of mist droplet, increase deposition of the pesticide on target, improve
The effective rate of utilization of pesticide, improves agroecological environment.
