A spray drift performance test device

Abstract

The invention relates to a spray drift performance testing device. The spray drift performance testing device comprises a simulation chamber, a gas rectifier, an atomizing nozzle, a measuring module, a drift acquisition unit and a control cabinet. Both ends of the simulation chamber are provided with an air inlet and an air outlet. The gas rectifier is arranged on the side close to the air inlet in the simulation chamber to form a uniform air field in the simulation chamber. The upper portion of the simulation chamber is provided with a guide rail. The atomizing nozzle and the measuring module are slidably arranged on the guide rail. The drift acquisition unit is arranged on the side close to the air outlet in the simulation chamber. The measuring module is connected to the control cabinet. The control cabinet is connected to the drift acquisition unit, an air inlet mechanism and an air outlet mechanism. The spray drift performance testing device can establish a controllable standard test environment for testing the drift performance of droplet and collected related data can provide accurate set parameters for actual operations of a sprayer, so that spray liquid waste is reduced and pesticide pollution to the environment is accordingly reduced.

Description

technical field [0001] The invention relates to the field of plant protection equipment, in particular to a spray drift performance test device. Background technique [0002] In the application of chemical pesticides, drift is always an important factor affecting the application effect and causing environmental pollution. Large-scale aircraft spraying or ground mechanical spraying will inevitably cause environmental pollution because a certain proportion of droplets cannot reach the target. The purpose of improving the spray mechanical test is how to reasonably select the use parameters of the spray device and effectively control the spray conditions, reduce the amount of drift, and minimize the harm caused by drug drift. Although the field drift test is closer to the actual situation, the factors affecting the droplet drift cannot be controlled in the field. The momentary variation of wind speed and direction in the field makes it quite difficult to obtain an accurate dat...

Although the drift test in the field is closer to the actual situation, the factors that affect the drift of droplets cannot be controlled in the field

The momentary variation of wind speed and direction in the field makes it quite difficult to obtain an accurate data, and these uncertain factors make there are considerable differences between repeated experiments
