Spray-volume vertical distribution measuring method and special measuring device

Abstract

The invention relates to a spray-volume vertical distribution measuring method and a special measuring device, and belongs to the technical field of agriculture and forestry engineering test. The method comprises the following steps: setting a fog droplet acquisition device and a liquid volume distribution measuring instrument, placing an atomizing machine or a spray head to be measured in front of the fog droplet acquisition device, starting a power device, intercepting droplets after the fog droplets enter the fog droplet acquisition device, depositing the droplets on each layer of liquid accumulating groove from the top to bottom, and reading accumulated liquid volume in each liquid accumulating tube after the droplets enter each liquid accumulating tube of the liquid volume distribution measuring instrument through a guide tube so as to acquire a fog droplet vertical distribution volume measuring result. The fog droplet acquisition device consists of a fog droplet intercepting flow passage, and the lowest part of the fog droplet intercepting flow passage is provided with the liquid accumulating groove; the liquid volume distribution measuring instrument consists of a row of vertical liquid accumulating tubes; and the lowest part of each fog droplet intercepting flow passage is connected to the liquid accumulating tubes through the guide tube in turn respectively. The invention not only provides accurate and efficient detection means for the detection of spray volume performance of plant protection machinery, but also provides scientific basis for the optimization of operation parameters of the atomizing machine.

Description

technical field [0001] The invention relates to a method for measuring the spray amount, in particular to a method for measuring the vertical distribution of the spray amount, and also relates to a special measuring device for the vertical distribution of the spray amount, which belongs to the technical field of agricultural and forestry engineering testing. Background technique [0002] As far as the applicant knows, in various performance tests of the sprayer, the deposition uniformity of the spray droplets in the canopy is an important index to measure the quality of spraying, so it is possible to quickly and accurately detect the droplet (or gas-liquid mixture) on the target The distribution of liquid medicine deposition in the canopy is of great significance to improve the detection technology level of plant protection machinery and optimize the parameters of spraying operations. [0003] At present, there is a set of detailed and accurate measurement methods for the de...

Problems solved by technology

However, the existing test methods cannot be applied to the vertical distribution measurement of the spray volume. Therefore, the vertical distribution of the spray volume on the target is still measured by manual arrangement and sampling. It is difficult to obtain the droplet deposition information accurately and quickly.
