Desenvolvimento de protótipo de implemento agrícola para limpeza de pomar de maçã

Abstract

Over the years, the field of agricultural activity has undergone technological innovations to increase work efficiency. In the mid-nineteenth century, the development of technology in the manufacture of implements gained momentum, and they became more present in the properties. As a result, artisanal production became insufficient, resulting in the need for greater investment in manufacturing, in order to meet infinite demands. Thus, following the trends to facilitate work in agriculture, this work aimed to develop a prototype of an agricultural implement for use in apple orchards, which enables the complementation of existing technologies in these environments, being used to aid in cleaning the orchards. After the production of the prototype, which features a rotating bristle system for cleaning, a side opening, tilt and expansion system, facilitating its use in different terrains, it went on to field testing. Thus, it was possible to analyze the operation in different row structures, which resulted in the conclusion of the need to use a motor with a higher torque than that initially tested, an inclination system to compensate for the unevenness of the ground, and a reduction in the length of the bristles, due to the high number of branches and uneven terrain.
