          Abstract

          Resumen: En Ecuador, la producción agrícola destinada al consumo depende en gran medida del cultivo y trasplante de plántulas obtenidas mediante un proceso manual que implica la colocación individual de semillas en las cavidades de almácigos. Esta investigación se enfoca en el diseño de un prototipo de sembradora para la colocación semiautomática de semillas con el objetivo de reducir el tiempo dedicado a esta actividad en el proceso agrícola. El prototipo, que incorpora componentes eléctricos, neumáticos y mecánicos, presenta versatilidad para adaptarse a semillas de cuatro a diez mm. La composición óptima se determinó mediante un enfoque deductivo y exploratorio. Las pruebas confirmaron que el prototipo reduce el tiempo de siembra manual de cinco a tres minutos, especialmente en situaciones que requieren grandes cantidades de almácigos de manera continua, lo que representa una disminución del 40% en el tiempo por bandeja sembrada. Además, es esencial considerar el costo asociado, aproximadamente ochocientos diez dólares, lo que posiciona esta propuesta como una inversión altamente rentable. Este resultado sugiere un beneficio significativo para el sector agrícola al implementar este dispositivo en el proceso de siembra, especialmente para emprendedores y pequeños productores.

          Abstract: In Ecuador, agricultural production destined for consumption relies heavily on the cultivation and transplantation of seedlings obtained through a manual process involving the individual placement of seeds into nursery seedling cavities. This research focuses on designing a seed planter prototype for the semi-automatic placement of seeds, aiming to reduce the time dedicated to this activity in the agricultural process. The prototype, incorporating electrical, pneumatic, and mechanical components, demonstrates versatility in accommodating seeds ranging from four to ten mm. Optimal composition was determined through a deductive and exploratory approach. Trials confirmed that the prototype reduces manual planting time from five to three minutes, particularly in scenarios requiring continuous transplantation of large quantities of seedlings, representing a 40% reduction in time per seeded tray. Additionally, it is crucial to consider the associated cost, approximately eight hundred and ten dollars, positioning this proposal as a highly profitable investment. This outcome suggests significant benefits for the agricultural sector upon implementing this device in the planting process, especially for entrepreneurs and small-scale producers.
