Diseño de una sembradora de disco de tracción automotriz.

Abstract

The present title work presents the design and simulation of a motor drive disc planter, this project was carried out using Autodesk's Inventor software for design, assembly and simulation. The motor drive planter was designed taking references from previous books, theses and projects, to achieve a simple and farmer-friendly model. The hopper was sized from the calculation that was made of the amount of grains with which the hopper will be filled, using values that determine the sowing of the grains such as the area of a hectare 10.000 , the separation distance between rows 0,8 (m), the distance between sown grain 0,15 (m), where a result of 62.500 grains needed to complete the sowing process of 1 hectare was obtained. The number of turns made by the wheel in a linear meter was determined, which was used to calculate the transfer of movement from the wheel to the dispenser, resulting in 1 turn in 1 linear meter, the calculation of alveoli was carried out where obtained a result of 6 alveoli in the dispenser, it was found that in this way a sowing distance of 0,15 (m) between grains is obtained. The cutting force of the soil type loam 362,2 (N) and the pulling force of the tractor of the Johny Deere brand model 5036c 12.025,25 (N) were calculated, which were used for the design of the front and rear furrowers.
