Detailed description of the invention
This wind curtain type air-flow auxiliary flow guide system is further illustrated below in conjunction with accompanying drawing.
In detailed description of the invention as shown in Figure 1, Figure 2, Figure 3 shows, a kind of wind curtain type air-flow auxiliary flow guide system, is made up of frame 1, converter 2, wind speed wind direction sensor 3, axial flow blower 4, air curtain air bag 5, Weight plate 6, motor 7, flow controlling bar 8, sealing gasket 9, gland 10, clip 11, little gear 12, gear wheel 13 and ventilating duct 14; Converter 2, wind speed wind direction sensor 3, axial flow blower 4 and motor 7 are arranged in frame 1 by bolt, flow controlling bar 8 is arranged in frame 1 by bearing, the air inlet end of air curtain air bag 5 passes through sealing gasket 9, gland 10 and clip 11 to be fixed with axial flow blower 3 and connects, little gear 12 is arranged on motor 7 by key, gear wheel 13 is arranged on flow controlling bar 8 by key, borehole jack on flow controlling bar 8 is on ventilating duct 14, and one_to_one corresponding.
This wind curtain type air-flow auxiliary flow guide system work process: first record the wind speed and direction of natural wind in working environment according to wind speed wind direction sensor 3, operator manually adjust the operating frequency (0��50Hz) of converter 2 and change the rotating speed of axial flow blower 4, change the air outlet wind speed (0��17m/s) of ventilating duct 14, driven the rotation of flow controlling bar 8 by the engaged transmission of the little gear 12 on motor 7 with gear wheel 13, change the air motion direction of ventilating duct 14; Determine that the frequency of converter 4 and flow controlling bar 8 are after correct position, proceed by operation, undertaken obliquely or Jet with downward flow direction by air-flow in ventilating duct 14 in wind curtain type air-flow auxiliary flow guide system, air-flow is pushed crop canopies open and is produced gap, intercept the natural wind interference to droplet simultaneously, droplet can be made to enter in crop canopies gap inside crop canopies on the one hand, droplet can be made to increase in the area coverage of crop on the other hand, thus being effectively improved the penetration capacity of droplet and reducing float of mist droplet.
One section of article of experimental verification: Wang Junfeng was mentioned a kind of air curtain airbag structure (agricultural mechanical journal: wind curtain type strength auxiliary electrostatic sprayed deposit characteristic, in February, 2012), the apparatus structure difference of documents: 1, do not have Weight plate below air curtain air bag, it is impossible to enough make air curtain guarantee stability and the spraying accuracy of air bag; 2, ventilating duct cylindrically shaped in document, neither the ventilating duct top of the present invention is divided into cone, bottom to be divided into cylinder, this structure more can make ventilating duct air-flow out more uniform; The contrast present invention and the air curtain air bag impact on float of mist droplet in disclosed document, test and be made up of collection mist testing & measuring system and spraying system, can float of mist droplet rate be detected; Collection mist testing & measuring system is made up of a folding mist type collecting tank, container and electronic balance, and spraying system is sequentially connected with by medicine-chest, membrane pump, pressure regulator valve and Fan spray head and forms; Refer to Fig. 4.
It is 0.5MPa and natural wind blows to air curtain air bag front at atomisation pressure, under the impact of wind speed average out to 4m/s, measures the drift rate of droplet and carry out Data Comparison. The present invention is according to the wind speed and direction recording natural wind, the operating frequency manually adjusting converter 2 changes the rotating speed of axial flow blower 4, change the air outlet wind speed (0��17m/s) of ventilating duct 14, the rotation of flow controlling bar 8 is driven by the engaged transmission of the little gear 12 on motor 7 with gear wheel 13, change the air motion direction of ventilating duct 14, wherein DfRepresent that the droplet gross mass sprayed by shower nozzle deducts the float of mist droplet rate of the droplet gross mass gained that the deposition collecting droplet sprays divided by shower nozzle; Q represents the droplet gross mass sprayed, the deposition of D droplet, is expressed as:
Observing the present invention and the impact on float of mist droplet rate of the disclosed document, table 1 is the float of mist droplet rate data recorded. Draw by comparing: the float of mist droplet rate of the present invention is less than the float of mist droplet rate of disclosed document, it is believed that: in the present invention, air curtain air-flow is can better to improve float of mist droplet rate situation.
In sum: in this patent air curtain air-flow can make that float of mist droplet rate becomes less, illustrate that anti-drift performance is better. Owing to always having natural wind when field rotating medicine, the twice air curtain formed with the boom sprayer of air curtain apparatus can prevent the interference of natural wind effectively, to reduce drift; Perturbation action is played in crop blade face by air curtain air-flow simultaneously, enhances penetration performance and the droplet area coverage of droplet.
