THEORETICAL JUSTIFICATION OF DESIGN AND OPERATING-TECHNOLOGICAL PARAMETERS OF AUTOMATED SEPARATING WORKING UNITS OF A POTATO HARVESTING MACHINE

Abstract

 The modern market for agricultural machinery is saturated with a large number of machines, both domestic and mainly imported. Consequently, this circumstance indicates the need to develop and select scientifically based machine systems, including the technological provision of machine complexes with digital equipment that allows monitoring the quality of a certain technological operation and interpreting the received information with a technical means to change the initial state of the affected object, which is current scientific problem. Purpose of the study. Justification of the design, operational and technological parameters of automated separating working bodies of a potato harvester. Material and methods. A systematization and generalization of modern technological processes for harvesting potatoes in seed production was carried out in a digital agricultural production system with elements of robotization of the separation process. A technology has been developed for automated potato harvesting technology in seed production. Research results. A structural and technological separating system for a potato harvester with a digital cleaning control system, a block diagram of an automated separating system for a potato harvester with a digital control system have been developed, the impact of a remote finger hump with an adjustable angle of inclination of the blade with elements of artificial intelligence has been simulated, ensuring the recognition of soil lumps and their separation from commercial potato products to tuberous heap in order to substantiate the design and technological parameters that ensure high separation completeness and minimal damage to commercial products. Discussion and conclusion. The theoretical principles of automated potato harvesting technology in seed production have been established.
