多功能组合式小型农机设计

ABSTRACTChina is a major agricultural country,and agriculture is particularly important in productionand daily life.In the cultivation of mountainous areas and household agricultural land,largemachinery is not conducive to entering the cultivation.Some areas often rely on human labor forcultivation,and small rotary tillers and small seeders have emerged.However,in the use of smallrotary tillers and small seeders,a large amount of manpower is often consumed,and the twomachines also cause resource waste,Therefore,how to reduce the consumption of manpowerduring their operation and integrate them into a single machine has become an important researchtopic at this stage.The rotary tiller is an important component of a small rotary tiller,and theditcher is a key component of a small seeder.The selection of the rotary tiller and ditcherdetermines the key to achieving normal cultivation of the machine.The design of multifunctionalcombined small agricultural machinery needs to consider the mechanism design,mechanicaldesign,mechanical principles,and other aspects described in the mechanical design manual.Atthe same time,it is necessary to combine relevant research results for reference and reference,inorder to develop stable,reliable,intelligent,modular,and lightweight multi-functional smallagricultural machinery.Key words:Rotary cultivator;seeder;Rotary tiller;Trencher;small-scale2
