SELECTION AND JUSTIFICATION OF THE THE SHORT-BOTTOM NOZZLES- PARAMETERS FOR SURFACE RAIN BY THE SPRINKLER MACHINE -KUBAN-TK-

G. V. Mishchenko

Abstract

In recent years, research and development works have been carried out in our country to create a modification of the sprinkler machine ?Kuban-L? with a set of equipment for controlling the sprinkling height (including the surface one), which allows reducing the average rain intensity and reducing the loss of irrigation water for evaporation and demolition by the wind. There are a number of issues that need to be clarified, despite the large degree of this product?s development such as the distribution of the quality of the rain?s spray along the length of the machine, the formation of parameters for reducing the intensity of rain, its energy characteristics, etc. The object of research is a set of equipment for controlling the height of the sprinkling of the sprinkler machine ?Kuban? (?Kuban-TK?). The purpose of the research is to substantiate and clarify the technical and agrotechnical parameters of this equipment. In the course of the research work, the collection, analysis, and previous studies were carried out, engineering calculations and variant studies of the most important parameters of the equipment?s set for sprinkling height control were carried out. As a result of the researches, the following parameters were established: the consumption of the sprinkler machine ?Kuban-TK? equipped with the kit - 200 l/s, the average rain intensity - up to 0.8 mm / min., the diameter of the rain drops - up to 1 mm. The results of the research work can be used in the finalisation of the specified set of equipment.
