On the issue of reducing energy costs for the movement of wide-range sprinklers

The most in demand for irrigation of areas are wide-range sprinklers, for example, sprinkler machine Kuban-LK1, which operates in a circular motion, which occupies more than 15% of the fleet of this type of equipment in the Russian Federation. Their operation in various operating conditions is characterized by complex soil and relief parameters due to high humidity, as well as the movement of running systems along the same trajectory (track) The article notes that the optimization of the parameters of the running systems of the Kuban-LK1 type multi-support sprinkler is based on the optimization of the irrigation surface-sprinkler system, which determines the parameters of track formation under the running systems of the machine, characterized by the height of the profile and types of tread. The issues of the influence of the soil squeezability index and the height of the soil hooks (depending on wear) of the pneumatic tires of sprinkler machine trolleys on the noted characteristics are considered. The data of analytical studies are presented, which make it possible to judge the practical applicability of tires with different profile heights under different operating conditions. At the same time, it is indicated that in order to reduce the energy costs of sprinkler machine movement, it seems advisable to use pneumatic wheels with a "stick" type tread instead of a standard "herringbone" type tread, and the height of the hooks exceeding the irrigation rate.
