THEORETICAL STUDIES ON STUDYING SPHERICAL AND TOROIDAL BODIES ROLLING ON THE EXAMPLE OF CUCURBITS FRUIT
Harvesting melon fruit is a complex process. Automation of the technological process of harvesting is one of the promising areas in this field of agriculture. Two ways of moving fruit are considered they are sliding and rolling. Two types of interaction of passive and active types of swath maker elements with fruit for their movement are presented. Passive type swath maker is designed to move fruit into a roll by sliding and active type swath maker by rolling. The design of the melonfield combine with active working bodies of the swath maker is the most promising. Theoretical studies are aimed at proving the hypothesis that the harvesting of fruit and loafs of cabbage should be carried out using rolling to create optimal parameters of the technological process. Theoretically, for the condition of the capture and rolling of the fetus in constant motion it is necessary that the sum of the moments relative to the point O be equal to zero. Rolling of the fetus will occur only if the offset is not less than the length of the segment of the recess: from the center of the fruit to the edge of the hole. The process of rolling fruit of various shapes along the surface of the field with the displacement of the contact point of the interaction between the fruit and the soil is considered.
