Abstract :
Today, the increasing use of chemical fertilizers has caused the destruction of soil structure and water pollution. In order to improve soil quality some methods such as crop rotation, biological control, application of green fertilizers and manure can be used. Adding animal manure to the soil increases the organic matter of soil, absorbable phosphorus, nitrate and other nutrients that are needed by plants. One of the main problems regarding usage of animal manure is its distribution method on the field. Therefore, the purpose of this research is to design and construct a centrifugal manure distributor machine. This machine is drawn and supplied by tractor and consisted of different parts including hopper, chain conveyor, distribution unit, divider plate and axle. The volume of hopper is 6 m3 and the distribution width is designed for 9m and more. The drawbar power requirement and PTO power requirement of this machine are calculated 8.1 and 52.77hprespectively and it can be supplied by conventional tractors like MF-285 or MF-399. CATIAv5 software is used for analysis of the axle system of machine. After modeling and defining the material of axle system, it is analyzed by finite element method. The maximum stress and safety factor are determined to be 139MPa and 1.8, respectively
