SYNTHESIS OF THE MODERN AGRICULTURAL MACHINES TECHNICAL MAINTENANCE ORGANIZATION FORM, TAKING INTO ACCOUNT THE PECULIARITIES OF THE OPERATION OF THEIR HYDRAULIC DRIVES IN THE AGRICULTURAL SECTOR OF UKRAINE

Abstract

The domestic scientific and methodical principles of the organization of the system of technical maintenance and repair of agricultural machines today do not fully comply with the established material and technical capabilities and market relations that have developed in the agro-industrial sector of Ukraine, directly in the context of hydraulic machines, which are equipped with modern agricultural machinery. Decomposition of the theoretical structure of the organization of technical maintenance and repair of components of agricultural machines, further analysis of its elements made it possible to identify a number of factors: subjective distribution of service personnel, improperly organized exchange of experience between equipment operators within the enterprise, no reward for independent elimination of equipment failures by own efforts, an unhealthy level of competition between equipment operators during seasonal agricultural works in accordance with the terms of their implementation, which affects the quality of repair and maintenance work of hydraulic equipment. As a result of solving the identified issues of the maintenance and repair system, a system of restrictions has been proposed, which reflects the control of the efficiency indicators of the operators of the equipment due to their compliance with the values of the performance factor of the norms of agricultural technical works, changes in the time of performing agricultural technical works and restoring the efficiency of hydraulic drives. Based on the proposals, an algorithm has also been built to eliminate the failure of machines in the organization of maintenance and repair due to the depersonalization of the items of the machine and tractor fleet. The presented form, to a greater extent, is based on the minimization of the negative effects of the human factor, which prevent the objective organization of the work of equipment operators in the agro-industrial sector of Ukraine, which allows to reduce the average downtime of equipment and the deadlines for performing agricultural technical works due to the reassessment of the role of the qualification of equipment operators in service maintenance aggregates of hydraulic systems. The theoretical efficiency of the developed form of organization of maintenance and repair of agricultural machinery will boost with an increase in the number of machines in the machine fleet of the agricultural sector, and proposals involving a change in the system of exchange of experience between machinery operators require a sufficient number of workers and machinery to ensure the possibility of solving tasks in pairs to avoid working equipment downtime.
