Substantiation of the structural and functional scheme of the technical means based on a multi-copter for the introduction of plants protection

Abstract

Annotation Purpose. Improving the quality of distribution of technological material by choosing a rational scheme of the multicopter and technological equipment for it. Reduction of damage to crops by terrestrial technical means in the process of plant protection through the development of a distribution and dosing system for multicopters. Methods. The designs of multicopters are analytically investigated and the construction scheme of the multicopter and technological equipment is determined. Results. The designs of multicopters are analyzed, and the design of the multicopter and the layout of the technological equipment are substantiated. The analysis of technological equipment for application with the use of plant protection multicopters is given. Based on the analysis of multicopter designs and their technological equipment, the advantages of their work are determined: they depend less on weather conditions and plant condition, but have a number of disadvantages, such as insufficient uniformity of material distribution and low productivity. Conclusions 1. It is established that with the appropriate improvement, multicopters will perform the vast majority of work when applying plant protection products, especially on wet soils. 2. During the technological operation of spraying, the performance of the multicopter is reduced by 20 % compared to the AIT due to the cost of working time to replace the battery. 3. The distribution of material on the surface of the field by multicopters, when performing a technological operation has a high unevenness (up to 70 %). 4. To increase the productivity and quality of the working fluid distribution, it is necessary to change the layout of the drive propellers and process equipment in the design of the multicopter.
