MATHEMATICAL MODELING AND GRAPHICAL REPRESENTATION WITH AUTOCAD OF THE FUNCTIONING OF VEGETABLE REMAINS SHREDDERS

Abstract

Agricultural work is considered the oldest human occupation, being determined mainly by the need for insurance of the food necessary for survival. The positive evolution of human civilization has generated an increase and diversification of food needs, thus contributing to the improvement of work techniques and the modernization of tools and equipment used in agriculture. One of the current scientific research topics in the agricultural field is related to the problem of clearing land of vegetable remains by cutting, chopping and then uniformly distributing the chopped material on the soil surface in order to ensure optimal conditions for carrying out agricultural work necessary for the future crop on that land. This article presents a mathematical modeling of the operation of a vegetable remains shredder, which aims to permanently verify the characteristic working parameters in accordance with the optimal values indicated by the manufacturers of these machinerys. The equations of the mathematical model allow the calculation of the desired working parameters at different time intervals, for certain values of the machinery's travel speed or drum rotation speed. A scale graphic representation of the cutting elements is also made, as well as a graphic simulation of the operation of the vegetable remains shredders. For this, the facilities offered by the commands in AutoCAD are used, which is a computer application that allows drawing and graphic design aided by computer.
