Melhorias no projeto da caçamba de uma máquina colheitadeira de milho

Abstract

Over the years, several technological advances have occurred in the field of agriculture, so that improvements could be made, facilitating the harvest, reducing its costs and execution time, and increasing sales and profits. Thus, companies seek daily ways to further optimize their services to reduce existing competition (already quite fierce), increase the number of customers and, consequently, the number of sales. For this reason, this project aims to propose improvements to a dump box that is coupled to a corn harvester, including increasing the storage volume of this dump box and designing a functional conveyor belt to assist the process of evacuating corn from the dump box. To carry out this project, a corn harvester model already established in the market was taken as a basis, its parts were modeled in SolidWorks software based on real measurements and a dump box format with a larger volume was designed based on empirical observations of improvement for the machine, in addition, a conveyor system was designed to meet the need to improve the evacuation of corn from the dump box. With this project, it was possible to achieve an increase of 3.4 % in the storage volume of the dump box, a structure that safely supports the efforts caused by the new load capacity, absence of interference with the rest of the harvester machine and a conveyor belt design which addresses the difficulty of tipping corn due to its abrasiveness and tendency to pool at the bottom of the dump box during tipping.
