Design of a mechanical seeder

Abstract

In the agricultural production processes that are carried out in most of the Colombian regions, some deficiencies can be observed in the way in which the seeds are sown. This is a task that is carried out manually, generating physical problems in the workers due to the enormous effort that they must make, in addition to the precariousness in how these works are carried out. The long periods that are involved in sowing greatly hinder its efficiency, something that directly affects the economy of the farmers. The purpose of this work is to design a mechanical seeder that facilitates the work of the operators by eliminating the manual operation of it and equipping them with equipment that performs the furrows in the ground and at the same time sows the seed. The results obtained corroborate that there is an adequate structural design, which will support the forces to which the machine will be subjected. In this way, it will be possible to contribute to the improvement of the sowing conditions of the farmers of the region. This design takes into account the number of seeds sown per hectare, which is about 20 kg. These data were obtained from farmers belonging to the Universidad Francisco de Paula Santander seccional Ocaña. Additionally, maximum deformation analysis was performed on the chassis, obtaining values of 1.791×10−4 m, as well as structural analysis using the Solidworks drawing tool.
