A sliding seat 2 is provided on the track 1, an adjusting mechanism 4 is provided on the sliding seat 2, a measuring mechanism 5 is provided on the adjusting mechanism 4, and the driving mechanism 3 is arranged between the track 1 and the sliding seat 2 for driving the sliding seat 2 to move. The driving mechanism 3 includes a rack 31, a motor I 32 and a gear 33. The rack 31 is arranged on the track 1, the motor I 32 is arranged on the sliding seat 2, and a gear 33 meshing with the rack 31 is provided on the rotating shaft of the motor I 32. It further includes a laser rangefinder 6 and a reflector 7. The laser rangefinder 6 is arranged at the front end of the track 1, and a reflector 7 cooperating with the laser rangefinder 6 is provided on the sliding seat 2. The measuring mechanism 5 includes a pulsed light source 51, an image collector 52 arranged corresponding to the pulsed light source 51, and an image processing system 53 connected to the image collector 52. The adjusting mechanism 4 includes two telescopic mechanisms 41 and two support columns 42 respectively arranged at the free ends of the telescopic mechanisms 41. The pulsed light source 51 and the image collector 52 are respectively arranged at the free ends of the two support columns 42. The telescopic mechanism 41 includes a telescopic assembly composed of a plurality of hollow tubes 411 sleeved and combined with diameters decreasing in sequence and a housing 415 communicated with the large end of the telescopic assembly. Adjacent two hollow tubes 411 are slidably and hermetically connected. An installation seat 413 is provided at the outer end of the hollow tube 411 with the smallest diameter, anti - detachment retaining rings 412 are provided at the outer ends of the remaining hollow tubes 411, and a blocking body 414 is provided on the outer peripheral surface of the outer end of each hollow tube 411. A winding mechanism 416 is provided in the housing 415, a pull rope 417 fixedly connected with the installation seat 413 is provided on the winding mechanism 416, an air inlet 418 and an air outlet 419 are provided on the housing 415, and electric valves 4110 are provided on both the air inlet 418 and the air outlet 419. The winding mechanism 416 includes a winding disc 4161 and a motor II 4162 for driving the winding disc 4161 to rotate.

[0020] Working process of the present invention:

[0021] During the working process of a smart measurement device of an air - blown sprayer according to the present invention, when the measuring mechanism needs to adjust its position, the motor I 32 drives the gear 33 to rotate clockwise or counter - clockwise and move forward or backward along the rack 31, thereby driving the sliding seat 2 to adjust its position.

[0022] When the adjusting mechanism 4 works, the electric valve 4110 on the air inlet 418 is opened, compressed gas enters the housing 415 through the air inlet 418. Under the action of air pressure, the telescopic assembly extends, and at the same time, the pull rope 417 is pulled for unwinding. After the telescopic assembly extends to the required length, the electric valve 4110 on the air inlet 418 is closed.

[0023] When the telescopic assembly retracts, the electric valve 4110 on the exhaust port 419 opens, and then the winding mechanism 416 winds the pull rope 417. The pull rope 417 pulls the hollow tube 411 through the mounting seat 413 to perform the retraction operation.

[0024] When the measuring mechanism 5 works, the pulsed light source 51 illuminates the measurement area. The image collector 52 quickly collects the shadow image of the illuminated area. The image processing system 53 analyzes the collected information, calculates the size of the fog droplets through the analysis of the projection contour of the fog droplets, and establishes the fog droplet size distribution spectrum by analyzing multiple images. By using the method of double-pulse illumination, the velocity of the fog droplets can be measured. The principle is that double-pulse illumination can generate two clear projections of each fog droplet at a certain moment, or generate two projections in the same picture, or generate images in two consecutive pictures, and then use a certain algorithm to analyze the images to obtain the velocity of the fog droplets.

[0025] The above embodiments are illustrative of the present invention, rather than limiting the present invention. Any simple transformation of the present invention also falls within the protection scope of the present invention.
