Crop fertilizer machine developed
The dossifier machine helps apply fertilizer directly to the root system and may be used on sloped or flat grounds. Farmers may carry it manually.Palmira, 30 de marzo de 2016 — Agencia de Noticias UN-
The equipment has a lever which adjusts to the height of the user and also has subsoil ploughs to help till the soil and a 20 liter tank, hoses for fertilizer distribution into the soil, tires for rugged terrain and a cushioned back plate.
The fertilizer machine which costs COL $300,000 (USD $97.66) could be sold for COL $200,000 (USD $65.10) or even less according to volume sales.
The item combines the functionality of a fertilizer machine and a backpack fertilizer sprayer. This helps apply the liquid fertilizer directly to the root system and optimize application, reducing waste and improving the occupational conditions of farmers. The item may be used in flat or slopped terrain without the need of a tractor.
As claimed by Universidad Nacional de Colombia (UNal) in Palmira Industrial Design senior Alejandro Arias Arango, who along with fellow undergraduate Erika Reina developed this idea as a solution for the needs of small Colombian farmers and for the design and production project node course headed by Professors David Ríos and Raúl Antonio Díaz.
In summary, the project was developed taking into account a case event of a firm in the Province of Valle del Cauca which provided liquid fertilizer services for large farms such as sugarcane crops. This firm hopes to enter the market with a new product directed to small farmers and this is how they came to this fertilizer sprayer to help market the product and also provide adequate application.
The main issue was to improve farmer fertilizer use through sprayers, backpack sprayers, etc. which wasted much of the fertilizer due to evaporation or the fertilizer blown by the wind; added by the fact that by foliar application, the fertilizer was not absorbed appropriately.
The students worked on a design method which combined procedures such as field visits, problem analyses and needs of the benefited parties, design, validation and testing the proposal as well as socializing the project.
The initiative was hand-drawn and later designed with help of a software program known as Rhinoceros® and the blueprint was produced in AutoCad™. To build the model they used elements such as high carbon steel to avoid oxidation and impacts.
The container is made of high-density polypropylene, injection levers and PVC tubing. Furthermore subsoil ploughs are made of aluminum, therefore the machine is lighter. The backpack is made of cushioned foam material and a strap-on Velcro® belt to avoid hernias.(Por: Fin/HAA/MLA/APBL
