Abstract
The article notes the importance of developments aimed at expanding the functionality of multi-support sprinkler machines, based on the bridge design and layout scheme of their spans. The main features of bridge units are similar in many ways to those of wide-reach sprinkler machines of the Kuban-LK1 type, a basic element that (a truss span with a support cart) can be taken as a separate module. At the same time, it is proved that the effectiveness of the design and application of a single-span circular bridge module is determined, to a large extent, based on its main purpose (sprinkling), the types and schemes of placement of rain-forming devices, as well as the design of running systems. Justified and recommended for use on the Kuban-LK1 DM irrigation of soil-seeing schemes of placement of sprinklers with the results of a positive assessment as an example of one of the methods (scheme 1) in the field are given. Based on the above, the driving systems for the self-propelled DM bridge trolley of circular action on moderate rigid wheels, pneumatic tires (figures 6,7,8 and 9), and crawler and walking engines were proved and tested positively. The analysis of technical solutions for running systems of sprinkler machines "Kuban-LK1" and the development of technical proposals on the basis of it to reduce their compacting effects on the soil allowed us to tentatively determine, based on the strength characteristics of the surface of the soil, the zones of their application. The experience of creating, on the basis of the above studies, an experimental section with a module based on the DM "Kuban-LK1", a bridge type with a preliminary expert assessment of its work is given. Analysis of search studies has shown that electrified multi-support sprinkler machines of the Kuban-LK1 type, when optimizing their rain-forming and running systems, can serve as a base and be fully used when creating multi-support bridge units with minor design modifications. In addition, the machine can be used as a power supply system to power other means of mechanization that work in the same process with it.
