ОЦЕНКА ПАРАМЕТРОВ ХОДОВОЙ СИСТЕМЫ «КУБАНЬ-ЛК1» ПРИ ЗАРАВНИВАНИИ КОЛЕИ

Abstract

Issues of increasing the reliability of the operation of reclamation systems, using the example of a multi-support sprinkling machine (DM) "Kuban-LK1", operating in motion in a circle, are considered in the work. It has been established that due to the increased mass of the DM structure, it becomes necessary to equip the running systems with propellers with an increased profile width. The use of a disk leveling device is proposed to eliminate the negative impact of the track from the running systems of the DM. It is noted that the Kuban-LK sprinkling machine, whose running systems are equipped with pneumatic tires of size 18.4R24, forms a track of up to 0.30 m or more. Taking into account the constant static pressure on the soil DM, the indicator of movers is justified - the bearing capacity of the soil, determined by the dependence of Professor A.I. Ryazantsev. According to exploratory studies, it was revealed that with an increase in the number of full revolutions of the machine on an irrigated surface, the values of the bearing capacity increase, on average, by 3.5 times, both with and without a leveling device installed, so it becomes necessary to install propellers with an increased specific pressure in comparison with serial samples. It was found in the course of laboratory, as well as laboratory and field tests, that when the DM "Kuban-LK1" moves, one wheel of its running system has a pressure equal to 16 kN, therefore it must be equipped with tires enlarged in profile. It has been experimentally found that the installation of propellers of the specified size reduces the power consumption of gearmotors by 25-26%, and also reduces the area of damage to agricultural products by an average of 33%.
