Introduction

GB/T 20183 "Mechanical spray equipment for plant protection" is intended to describe the test methods for mechanical spray equipment for plant protection. It is planned to consist of four parts.

Grouped into.

--- Part 1: Test method for spray nozzles for sprayers. The purpose is to describe the test method for the spray accuracy of hydraulic nozzles for sprayers.

--- Part 2: Test methods for evaluating the horizontal lateral distribution of hydraulic sprayers. The purpose is to describe three test methods to evaluate the horizontal lateral distribution of hydraulic sprayers.

Horizontal distribution of the amount of pesticide applied by the same type of sprayers.

--- Part 3: Test method for evaluating the performance of the system for regulating the amount of liquid applied per unit area. The purpose is to describe the amount of liquid applied per unit area.

Test conditions, test methods and calculation methods for quantity regulation systems.

--- Part 4: Test method for stirring the liquid tank. The purpose is to describe the performance of the stirring system in the liquid tank of plant protection machinery.
