Desenvolvimento de um mecanismo puncionador para dosagem de adubos

Abstract

Agricultural mechanization has been developed since the origins of agriculture, as there is a need for strength to carry out agricultural activities of soil turning, sowing or incorporation of organic matter, and over the centuries, instruments and mechanisms that farmers have improved they used animal power for agricultural activities In the 19th century, the development of new technologies in the production of agricultural machines and implements gave an exponential boost in agricultural productivity, and they became more present in agricultural properties. In Brazilian agriculture, agricultural mechanization is an essential factor for competitiveness in the world agricultural market, as it presents greater productivity and reduced production costs per area. One of the great benefits of mechanization is the introduction of new production technologies that allow better management of agricultural inputs, avoiding waste. At the same time, the machines are tools for collecting and processing data, allowing for a diagnosis of the conditions faced in the field. Fertilizer is one of the most expensive agricultural inputs, representing 25 to 35% of the cost of agricultural inputs and considering that 70-80% of mineral fertilizers consumed in Brazil are imported (ANDA, 2021) and their purchase price in dollars, we owe use this resource with maximum efficiency to avoid waste and optimize production. For this, a virtual prototype was developed to meet the agronomic requirements, a punching mechanism designed in an INVENTOR CAD software system. After developing the components made in CAD drawings, they were converted into 3D printing codes, where it was possible to manufacture the components in a 3D printer using thermoplastic polymer (PLA). In order to develop a mechanism capable of carrying out the fertilizing operation as efficiently as possible, we sought to develop a solid fertilizer metering punching mechanism that punctually applies the right fertilizer dosage at the right distance in the correct spacing with inside operation speeds of the field application reality. The main objective of the pit punching fertilizer project is to study new solutions for applying granular solid fertilizers with minimal soil disturbance.
