In the article, a mathematical model of the movement of a water drop flying out of a nozzle with a deflector nozzle during artificial rain was built. The resulting equations were solved by an approximate method using a specially developed program at EHM. The parameters affecting the irrigation process were analyzed based on the obtained results.

The paper is devoted to the study of deflector nozzles of rain irrigation machines. The selection of the parameters of the deflector nozzle of artificial sprinkler irrigation machines on a scientific and practical basis allows for the correct organization of ecologically safe irrigation. The article presents the results of the scientific research of the parameters of a short-distance irrigation nozzle with a deflector.

This work aims to substantiate the effectiveness of the use of an active working body on a front plow. The necessity of using active working bodies is justified, and a front plow with passive and active working bodies is proposed. The efficiency of installing an active working body on a front plow is analyzed. The forces acting on the combined frontal plow are considered. The analysis of the influence of the active working body on the stability of the movement and the traction resistance of the front plow is carried out. The results of experimental studies of a frontal plow with active and passive working bodies are presented. The use of an active working body on the front plow increases the degree of soil crumbling by 8,5%, reduces the traction resistance and specific fuel consumption by 14,7% and 17,2%, respectively, and increases the productivity of the unit by 11,3%.

The technology of sprinkler irrigation has a higher coefficient of land use compared to that of regular irrigation, due to the absence of irrigation erosion, the prevention of unnecessary absorption of water into the soil, the high degree of mechanization and automation of the irrigation process, the saving of equipment and fuel costs, the availability of irrigation in areas with uneven relief, the uniform moistening of the root layer. It has the advantage of achieving the same growth and development of the plant in all parts of the field. At the same time, there are opportunities to achieve savings as a result of giving mineral fertilizers in the form of suspension during irrigation. This article examines the distribution of water droplets on the field surface during sprinkler irrigation and the influence of wind speed on the intensity of irrigation. Water drop motion and wind motion were analyzed in one coordinate system. As a result, a mathematical model of the resistance coefficient of the environment and the movement of a water droplet in a variable environment was developed.
