Ratio-switchable pesticide mixing device suitable for plant protection unmanned aerial vehicle

Abstract

The invention relates to a ratio-switchable pesticide mixing device suitable for a plant protection unmanned aerial vehicle. The ratio-switchable pesticide mixing device comprises a liquid storage tank, a liquid supply tank, a mixing tank and a buffer tank, a high-concentration liquid medicine is injected into a first chamber, water or an additive aqueous solution is injected into a second chamber, the proportion of the liquid in the first chamber and the liquid in the second chamber entering the mixing box is controlled by opening and closing the valve, therefore, pesticides with three proportions can be formed by mixing in the mixing tank, in practical operation, the weight of the liquid storage tank and the liquid in the liquid storage tank is far greater than that of other parts such as the liquid supply tank and the mixing tank, the load of the unmanned aerial vehicle is not obviously increased, the internal spaces of the mixing tank and the buffer tank are small, the pesticide liquid with the preset concentration can be sprayed on the target land block by arranging a narrow transition zone between different test land blocks, the pesticide liquid with different concentrationsdoes not need to be stirred in batches, and heavy-load operation of a large number of invalid strokes is not needed.

Description

Technical field [0001] The invention relates to a switchable pesticide mixing device suitable for plant protection drones. Background technique [0002] Due to the continuous outbreak of rice pests, the amount and frequency of pesticide application in rice fields have increased sharply, and the safety of rice is of concern. On the one hand, chemical residues are related to pesticides, and more importantly, they are caused by unscientific application and backward application technology and equipment. In order to explore scientific time, scientific methods and suitable pesticide application, aviation pesticides need to be studied. In the spraying operation, the low-volume application technology, the deposition law of pesticides on the leaf surface of the rice, compared the high-concentration reduction aerial spraying method and the conventional spraying method, to study the impact of the two operation methods on the quality of rice. In the prior art, when implementing spraying ope...

AI Technical Summary

Problems solved by technology

In the prior art, when carrying out spraying operations with different concentrations, different batches of pesticides with different concentrations need to be carried on the plant protection drones and then sprayed. Inject another concentration of liquid medicine into the container. In addition, the drone needs to rise and fall multiple times, and repeatedly fly over some plots to generate a large number of invalid trips; the test cost is high and the efficiency is low
