Abstract

The invention discloses an apparatus for testing a spray drift distance of a plant-protection unmanned aerial vehicle. The apparatus includes a frame. A fan, a spray head, a wind sensor, a fan regulation control button, a water collection plate, a collecting tank, a flowmeter, a variable frequency pump, and a water tank are disposed on the frame. The wind sensor monitors a wind scale of the fan. The fan regulation control button controls start and stop of the fan and a wind magnitude. A middle cross bar is disposed between the top and the bottom of the frame, the water collection plate is disposed on the middle cross bar, the collecting tank is installed outside the middle cross bar, and an end of the water collection plate extends into the collecting tank. A baffle is disposed at the topof the frame and around the middle cross bar to the top of the frame except a side on which the collecting tank is installed. The apparatus realizes a spray drift distance test of an unmanned aerial vehicle spray head under different scales of wind indoors, avoids complexity and result uncertainty of an outdoor flight test, and provides effective test data for spray performance and a wind resistance class of the unmanned aerial vehicle spray head. In addition, the invention further discloses a method for testing the spray drift distance of the plant-protection unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the manufacturing and testing technology of agricultural intelligent equipment, and in particular relates to a spray volume drift testing device and method of a plant protection drone. Background technique [0002] With the development of drones, more and more industries have begun to use drones for related operations, and plant protection drones have strong adaptability, high work efficiency, save labor, and reduce the risk of pesticide poisoning of operators. And many other advantages, it has a good development prospect in the field of agriculture, forestry, aviation and plant protection at home and abroad. However, during the actual operation, it was found that the plant protection drone will be disturbed by the external wind force during the spraying operation, which will cause the sprayed spray to drift, so that the amount of spray applied to the plants will be reduced, resulting in a waste of spray. Therefore, the nozzle...
