Description
Technical field
The utility model relates to a kind of spray amount determinator, and especially a kind of spray-volume vertical distribution measuring device belongs to agricultural Engineering Testing Technique field.
Background technology
Understand according to the applicant; in the various performance tests of spraying machine; the deposition uniformity of droplet in canopy is to weigh an important indicator of dispenser quality, and it is significant to improving equipment for plant protection detection technique level and optimizing the spraying job parameter therefore to detect the soup deposition distribution of drop (or gas-liquid mixture) in the target canopy quickly and accurately.
At present domestic horizontal distribution to spray amount measure an existing cover in detail, accurate assay method, the Chinese patent application that for example application number is 200520077300.6, name is called " spray nozzle integrative performance microtest platform " promptly discloses a kind of device of realizing the spray nozzle integrative performance test.Therefore yet existing method of testing can't be applied to the vertical distribution measuring of spray amount, and droplet spray-volume vertical distribution measuring on target is still taked the mode of manually layouting, sampling so far, is difficult to obtain quickly and accurately mist droplet deposition information.
The utility model content
The technical matters that the utility model mainly solves is: a kind of spray-volume vertical distribution measuring device is provided, thereby is to determine the means that drop (or gas-liquid mixture) mist amount distribution in vertical direction provides science fast, accurately.
Technical solution of the present utility model is: the spray-volume vertical distribution measuring device comprises fog droplet acquisition device and liquid measure distribution recognizer, described fog droplet acquisition device is by constituting by the gas-liquid separation runner of measuring the requirement arrangement from top to bottom, and the lowest part of described gas-liquid separation runner has the hydrops ditch; Described liquid measure distribution recognizer is made of the vertical liquid trap of a row, and the quantity of the quantity of described liquid trap and described gas-liquid separation runner is corresponding; The lowest part of described each gas-liquid separation runner is connected to each liquid trap according to the order of sequence by skirt respectively.
During mensuration, before spraying machine to be measured (or single shower nozzle) placed fog droplet acquisition device, device turns on the power, after droplet enters fog droplet acquisition device, because the flow field structure of the inner gas-liquid separation runner of fog droplet acquisition device and the physical characteristics of drop itself, smooth and easy the passing through of air-flow energy, (loss) quilt that splashes is effective to be tackled in each the lamination liquid ditch that is deposited on from top to bottom and drop does not have substantially, enter into each liquid trap of liquid measure distribution recognizer by skirt, thereby make droplet vertical distribution amount on analyzer, obtain showing.
This shows that the utility model not only provides precisely for spray volume performance detects, detection means efficiently, and provide scientific basis for the optimization of spraying machine job parameter.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the cross section structure for amplifying synoptic diagram of gas-liquid separation runner among Fig. 1.
Embodiment
Embodiment one
The spray-volume vertical distribution measuring device of present embodiment comprises fog droplet acquisition device 1 and liquid measure distribution recognizer 2 as shown in Figure 1.Fog droplet acquisition device 1 is by being supported on the two side stand 1-1, from top to bottom by measuring the gas-liquid separation runner 1-2 formation that requirement is arranged, each gas-liquid separation runner as shown in Figure 2, on V-shaped adjacent in cross section, bottom guide 1-3,1-4 constitutes, the lowest part of gas-liquid separation runner 1-2 forms circular arc hydrops ditch, the lower surface of upper guide plate 1-3 is positioned at hydrops ditch top place and forms that shape is curved prolongs and opening cuts liquid fork 1-5 facing to first circular arc of airflow direction down, and the upper surface of bottom guide 1-4 is positioned at contiguous exit and forms curved prolong and opening cuts liquid fork 1-6 facing to second circular arc of airflow direction up.Has one group of section liquid rib 1-7 that is parallel to hydrops ditch length direction in the hydrops ditch.By the V-shaped flow road of bending and cut structure such as liquid fork, airflow smooth is passed through, and the lossless substantially quilt of drop effectively interception be deposited in the hydrops ditch, thereby realize and will effectively separate through the gas-liquid of runner.
The hydrops groove is formed on the bottom that first circular arc cuts liquid fork 1-5, and the bottom land place of hydrops groove is positioned at 1/2nd places of gas-liquid separation runner 1-2 Width, and separating effect is ideal like this.
Liquid measure distribution recognizer 2 is made of to the vertical liquid trap 2-1 in support 2-1 a socket as shown in Figure 1, and the quantity of liquid trap 2-1 equates with the quantity of gas-liquid separation runner.
The all contiguous side stand 1-1 of the hydrops ditch of gas-liquid separation runner and the lowest part of hydrops groove, connection is drawn out to skirt 3 from here, and is connected to each liquid trap 2-2 according to the order of sequence by each skirt respectively.
During mensuration, spraying machine to be measured (or single shower nozzle) is placed preceding 1.5-2 rice of fog droplet acquisition device, device turns on the power, (or air-flow is auxiliary at fluid power for droplet, wind speed is not more than 5m/s) effect under, after entering fog droplet acquisition device, because the flow field structure of the inner gas-liquid separation runner of fog droplet acquisition device and the physical characteristics of drop itself, smooth and easy the passing through of air-flow energy, (loss) quilt that splashes is effective to be tackled in each the lamination liquid ditch that is deposited on from top to bottom and drop does not have substantially, enter into each liquid trap of liquid measure distribution recognizer by skirt, thereby make droplet vertical distribution amount on analyzer, obtain showing.
