Variable spraying control system testing device

The utility model relates to the technical field of plant protection machinery, and provides a variable pesticide spraying control system testing device which comprises a platform support, a liquid storage tank, a hydraulic pump and a spraying assembly, and the liquid storage tank, the hydraulic pump and the spraying assembly are arranged on the platform support. The liquid storage tank, the hydraulic pump and the spray head are sequentially connected through a pipeline; the platform support is further provided with a flow blocking structure, the flow blocking structure is arranged on one side of the spray head, and fog drops sprayed by the spray head can be condensed on the flow blocking structure. When the variable spraying control system testing device is used for indoor spraying delay time testing, fog drops can be prevented from drifting to other indoor areas, and potential safety hazards caused by the fog drops to electric equipment are reduced. 本实用新型涉及植保机械技术领域，提供一种变量喷药控制系统测试装置，所述变量喷药控制系统测试装置包括平台支架以及分别设
