Vertical spray quantity distribution test device and test method thereof

Abstract

The invention discloses a vertical spray quantity distribution test device and a test method thereof. The test device is provided with a spray drop delamination collector, a liquid collecting unit array, a liquid collecting quantity automatic checking system, an automatic liquid discharge system and a control system, wherein the spray drop delamination collector is provided with a spray drop deposition plate and a horizontal spray collecting range regulator, divides the spray drop deposition region into a plurality of horizontal strips with adjustable horizontal widths, collects the spray drops deposited in each strip, and guides the spray drops into a corresponding liquid collecting unit; the liquid collecting quantity automatic checking system is provided with a plane coordinate shifting mechanism and a non-contact-type liquid level detection device, and can implement the automatic checking of the liquid collecting quantity; the automatic liquid discharging system is provided with a vacuum pump and a main branch liquid absorption pipeline, and can complete the liquid discharge region by region of a liquid collecting unit array; and the control system controls each part to operate coordinately, and sequentially completes the liquid level pre-detection, spray collecting and liquid collecting quantity detection, and liquid discharging and spray quantity distribution information processing. The vertical spray quantity distribution test device and the test method thereof can be widely applied to the automatic testing of vertical spray quantity distribution uniformity of each type of blasting sprayer.

Description

technical field [0001] The invention relates to a vertical fog volume distribution testing device and a testing method thereof, which are used for testing the uniformity of the vertical fog volume distribution of an air-driven sprayer, and belong to the technical field of agricultural engineering testing and measurement. Background technique [0002] The uniformity of fog volume distribution refers to the uniformity of the deposition and distribution of fog droplets on the target during the operation of the spray machine, and is an important indicator to measure the performance of the spray machine. The rapid and accurate detection of the uniformity of fog volume distribution is of great significance to improving the technical level of spraying machinery detection, optimizing the operating parameters of spraying machinery and improving the design level of spraying machinery.
