Repotenciación de una máquina sembradora de maíz de cuatro hileras con dosificador de fertilizante

Abstract

The purpose of this technology work was to repower a 4-row corn sowing machine with fertilizer dispenser of the agricultural Guadalupe S.A. company to improve its production. A matrix of evaluation was made, which allowed to find many findings and through this one the state of each one of the components of the sowing machine was verified with a qualitative approach. Using the diagnosis made to the machine it was proceeded to scan several elements that presented irreversible damage and complex geometry, using the SolidWorks software it was digitalized each one of the elements that conformed it, where the form of each one was established, previous to a calculation made for the selection and redesign of several elements of the machine that allows to fulfill the desired functionality. Using the resistance of materials, the selection of a square profile of steel ASTM A500 was made, which supports all the elements of the sowing machine, the analysis for the selection was made manually and with the help of the Software Ansys, finally the protocol of tests was made obtaining as a result a high efficiency of the sowing cars at different speeds of work, and so that the machine works correctly a plan of maintenance and an operation manual has been made to guarantee that this one works with the highest percentage of yield. In conclusion, the repowering machine has new mechanical elements that can be easily found in the national market, and suitable for the sowing of most of the coarse grains, it is recommended that a more detailed analysis be made to the square profile considering the influence that it could have if the machine had an impact or the vibration caused by the tractor.
