Diseño y construcción de una picadora de papas, zanahoria y plátano para la alimentación de ganado vacuno de capacidad de 20 quintales por hora

Abstract

The surplus production of potatoes, carrots and bananas in rural areas allows farmers to use these previously washed and chopped products in cattle feed. The chopping of these products in safe sizes prevents choking, is executed manually, and is slow process. The processed product should not be stored for long periods of time because the oxide generated affects the health of the cattle, this condition defines the capacity of the machine. Due to the high cost of importing machinery, the increase in milk production and the surpluses of production, the present project is developed. The design and construction of a potato, carrot and banana chopper of 20 quintals per hour, for feeding cattle is necessary using manufacturing processes in our city through a study of alternatives of mechanical components and systems. The main mechanical elements are designed by ASME failure criterion. For generic components, selection tables are used, and for the basic components, only ergonomic dimensions are utilized. As result of capacity, cutting speed, weight, ergonomic and cost analysis, the machine accomplishes the specifications in the design
