Device of testing horizontal fog scale distribution and method thereof

Abstract

The invention discloses a device of testing horizontal fog scale distribution and a method thereof. The device comprises a horizontal fog collecting box array, a longitudinal and horizontal displacement mechanism, a partition liquid absorption type automatic liquid discharging system, a control system and a non contact type liquid level detection device; the horizontal fog collecting box array is formed in a manner that a plurality of square fog collecting boxes are arranged seamlessly in a form of line and column matrixes, and a corresponding liquid collecting unit array is arranged under the horizontal fog collecting box array; routing inspection of liquid collecting quantity is finished before fog scale distribution test; the horizontal fog collecting box array is used as a fog drip deposition plane for fog spraying, and the fog drips are collected in the corresponding liquid collecting unit; routing inspection of liquid collecting quantity of the liquid collecting unit array is carried out again, and a central processing unit (CPU) automatically calculates difference between detection results of the two liquid collecting quantities as the final liquid collecting quantity of each liquid collecting unit; and the automatic liquid discharging system is used to discharge collected liquid in each liquid collecting unit, and the CPU minimum system arranges fog scale distribution test results to obtain two-dimensional fog scale distribution information, so that the device and the method can be widely applied to automatic test of horizontal fog scale distribution uniformity of various fog spraying machineries.

Description

technical field [0001] The invention relates to a horizontal fog volume distribution testing device and a testing method thereof, which are used for testing the uniformity of the horizontal fog volume distribution of a spraying machine, 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.

Problems solved by technology

However, the disadvantages of these two test benches are: the horizontal fog collecting trough can only provide one-dimensional cumulative distribution information of fog droplets on the strip-shaped area, while the distribution of fog droplets on the horizontal target is a two-dimensional distribution. Therefore, Can not fully reflect the deposition distribution of droplets on the target
