Diseño y construcción de una sembradora de papas de dos hileras con un sistema de dosificación de fertilizante

Abstract

The objective of this project was the design and construction of a two-row potato seed drill with a fertilizer dosing system in order to solve the problems of shortage, high cost, and agricultural machinery low development in our country especially for the seeding potatoes. The design of this machine began with the previous studies to determine the characteristics of the potato and the mechanized sowing. Then the conceptual design was made to identify the most appropriate solution, later the elements that make up the potato planter were sized and selected with its respective simulation in the ANSYS software and it was developed its corresponding detail plans, which allowed to execute its construction and assembly. In addition, the maintenance and operation manuals of the machine were elaborated to guarantee its correct operation and durability. Finally, the functional and operating tests were carried out obtaining the following results an adjustable row distance of 1.40 to 1.50 m, a distance between seeds of 25, 30, 35, and 40 cm with a minor error than 1%, a fertilizer dispenser with regulation, and a layer of earth from 10 to 15 cm for the cover of the seed. In conclusion, the potato seed drill complies the strength and rigidity requirements, then it is a reliable and safe machine, which allows to carry out the sowing process satisfactorily. It is recommended to fill the hoppers with the number of seeds and fertilizer that was designed.
