A variable spraying effect test device for agricultural spraying equipment

Abstract

The invention discloses a variable spraying effect testing device for agricultural spraying equipment, which belongs to the field of spraying test platforms and includes a test chamber and a door arranged on one side of the test chamber. The inner wall of the bottom side of the test chamber is provided with a measuring Mechanism, the inside of the test chamber is provided with a moving mechanism and a micro-motion mechanism and a clamping mechanism arranged on the moving mechanism. The measuring mechanism includes a thermal imager and a laser particle size analyzer fixed on both sides of the bottom side of the test chamber. The bottom of the test chamber is close to both sides. The positions of the fixed rods are fixedly connected with a fixed rod, and the top of the fixed rod is threaded with two symmetrical fixed screws, and the outer wall of the fixed screw is fixedly connected with a fixed pressure piece, and the two fixed rods are connected by a fixed screw and a The fixed pressing sheet is fixed with a white paper sheet, which can realize, conveniently and reliably test the variable spraying effect of the drone, making the test structure more accurate.

Description

technical field [0001] The invention relates to the field of spraying test platforms, in particular to a variable spraying effect testing device for agricultural spraying equipment. Background technique [0002] At present, there are two main spraying technologies for agricultural plant protection machinery on the market, one is constant spraying technology, and the other is variable spraying technology. Agricultural plant protection machinery needs to turn when flying in the field, and it will generally slow down when turning. If it is a constant spraying technology, the flow rate will not be automatically adjusted as the flight speed slows down, which may cause excessive spraying of crops at the turning point of the field. It will cause phytotoxicity and waste pesticides. With the drone using variable spraying technology, the flow rate can be reduced as the flight speed slows down, so as to ensure that the amount of pesticide applied to every inch of farmland is equal and...

Problems solved by technology

[0003] After the production and configuration of the plant protection UAV, it is necessary to collect and analyze the spraying data under the conditions of the relevant spraying operation parameters, and to test the rationality and reliability of the relevant design of the plant protection UAV under each spraying operation condition. It conducts effect tests. At present, the spraying experiments of plant protection drones are basically completed in the field. There are many uncontrollable environmental variables such as natural wind, temperature difference changes, and humidity changes in field experiments, which have an impact on the experimental results of plant protection drone spraying variables. Therefore, field spraying experiments are not repeatable. For this reason, a convenient and reliable comprehensive plant protection UAV variable spraying test platform is needed
