Design And Dynamic Research Of Mower

Devote major efforts to developing mechanization of the livestock farming is essential condition about the modern agriculture of our country. Only when the livestock farming accomplish mechanization, the receipts of agriculture can be raised, and the living standard of the people can be improved. The technologies about hay planting, hay reaping and hay storing need improve in the livestock farming. The farmers need mechanisms of the reliable quality and the suitable price. So this can replace to be done by hand, and can raise benefit.The type of mowers is lack, and the structure of mowers is complex, the servicing and the employ of mowers are not convenient for the people. So we want to design the hay mower of the single disc rear mounted rotary and analysis the qualities of dynamic.The research and progress of hay reaping theory has firstly been discussed in this paper, then introduce the developing about foreign country, and cited the research situation in the years, and said the characteristic of quality in the new mower, and raised the developing tendencies about our mower.Secondly the basic structure of the mower has been defined after we discussed and screened, rear mounted rotary and single disc. The tractor can output power to mower. This hay mower has power transport and cushioning spring. Then this paper has studied the reaping practice, and analysis of force and movement of the blade and defined the numerical value.Then all parts are designed, calculated and intended effect. In addition, this paper has carried on the beneficial analysis of the hay mower on the basis of the designed mower, too.This paper has done modeling to analysis force and movement of the every part, and extracted roots. The paper has studied vibration or the mower, and MATLAB dynamic simulation, and raised the quality and speed of design ,and possessed important theory value.
