Embodiment Construction

[0027] The present invention is described in further detail now in conjunction with accompanying drawing.

[0028] Such as Figure 1-3 As shown, the droplet generating device includes an emitting end 1, a reflecting end 2, an imaging device 3, a light-emitting backplane 4, an ultrasonic signal generator 5, an auxiliary evaporation system 6 and a driving power supply.

[0029] The transmitting end 1 (ultrasonic piezoelectric transducer) is connected to the ultrasonic signal generator 5, and emits ultrasonic waves vertically downward, and the reflecting end 2 is arranged at the vertical relative position of the transmitting end 1, for reflecting the ultrasonic waves emitted from the transmitting end 1, The space between the emitting end 1 and the reflecting end 2 forms a droplet suspension area 7 . Ultrasonic levitation technology is used here, that is, acoustic levitation technology, which can be divided into standing wave levitation technology (Standing Wave Levitation) and n...

Abstract

The invention discloses a fogdrop generation device and method. The fogdrop generation device comprises a transmitting end, a reflecting end, an imaging device, a light emitting backboard and an ultrasonic signal generator. The transmitting end is connected with the ultrasonic signal generator and used for transmitting ultrasonic waves vertically downwards. The reflecting end is vertically opposite to the transmitting end and is used for reflecting the ultrasonic waves transmitted by the transmitting end, and the space between the transmitting end and the reflecting end forms a fogdrop suspension zone. The imaging device is arranged on the horizontal side of the fogdrop suspension zone and used for imaging fogdrops in real time. The light emitting backboard is horizontally opposite to the imaging device and is used for providing imaging lighting. An auxiliary evaporating system is further arranged on one side of the fogdrop suspension zone and used for accelerating evaporation of fogdrops. A vessel-free evaporation method is adopted, after large fogdrops injected by a traditional injector in a pushed mode are subjected to ultrasonic suspension, the particle size is monitored through an image processing method and is reduced through an accelerated evaporation method, and thus fogdrops with the designated particle size are obtained.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant protection, and in particular relates to a fog drop generating device and method. Background technique [0002] Chemical control is the main means of crop pest control, but the large-scale use of pesticides not only causes phytotoxicity to crops, but also causes serious harm to the environment. Therefore, efficient application reduction is the development direction of agricultural plant protection technology. The drift and deposition process of pesticide droplets is the research focus of efficient application reduction, and the randomness of droplet size has a great impact on the repeatability of experimental research. It is difficult to summarize scientific laws. [0003] The droplet size of the plant protection spray is mostly below 300 μm, and the aviation spray is even below 100 μm. The traditional spraying device has a large spray volume at one time, a large number of droplets, an...
