• Abstract:

  This project aims to develop the concept of a mushroom compost turning machine for operation at the Piccoletta Funghi mushroom farm in Goiânia. The scope of the work ranges from the initial sketch, through the selection of mechanical components, estimation of the positioning of each part, and the materials and manufacturing processes for these parts. The project is divided into seven modules: conveyor belt; collection platform; wheel system; vehicle movement; hydraulic system; chassis; and operator cabin. Many of the mechanical components of the final design are inspired by and imported from grain harvesters, such as the collection platform drum and the compost conveyor belt. In addition, the chassis structure is designed to prevent the center of gravity from shifting outside the tractor's stability base, thereby reducing the chances of tipping over, according to a manual from Hazards of Occupations Safety Training in Agriculture. The operator's cab was developed based on anthropometric studies to ensure ergonomic comfort for the operator. This cabin houses the seat and hydraulic controls, which are used to activate the four hydraulic motors that provide the torque and power necessary to operate the conveyor belt, harvesting platform, and rear wheels, which are independent. This project achieves its initial goal, as the machine has the mobility and adaptability necessary for working on small mushroom farms. A step beyond this work would be to build a prototype to analyze the vehicle's strengths and weaknesses and refine the design.
