Symbiotic Design Of Modular Silage Machinery Based On TRIZ Theory

Shandong province is one of the main producing provinces of corn,but also a large province of animal husbandry.With the gradual promotion of the policy of "grain to feed",the demand for silage machinery is also increasing.At present,most of the large silage machines abroad are suitable for large farms,but not suitable for the corn planting sites in the hilly areas of Shandong Province.Although the mechanization level of corn harvesting in China has been significantly improved,most of the functions are relatively single,and the supply of silage equipment suitable for the hilly areas of Shandong province is obviously insufficient,so it is necessary to develop a multi-functional modular silage machine with excellent performance and high adaptability.TRIZ theory believes that product innovation in any field follows certain objective laws,and designers can better grasp the development trend of products by mastering these laws.In today’s market competition,the design cycle is a key element of competition,and modular design is a rapid design method,according to the functional requirements of the various standard components can be rapidly integrated into a new product.Especially in the development of new agricultural equipment in China,a large number of standard parts are used to achieve some specific functions.However,in the process of module integration of various standard components,a series of module mismatch problems will be encountered.Therefore,this article will be introduced to the concept of symbiosis in the field of agricultural machinery design,and combining the theory of TRIZ are summarized five symbiosis principle,then a preliminary explore the modular symbiotic design method based on the theory of TRIZ,the method is divided into modules of the symbiosis between the layout and the module of symbiotic design two stages,guiding the modular design of agricultural machinery products.This method is applied to the design of silage machinery,namely,the modular symbiotic design of silage machinery based on TRIZ theory,which is divided into two stages: symbiotic layout of silage machinery modules and symbiotic design between silage machinery modules.In the symbiotic layout stage of the module,Feicheng city was selected as a typical location for user research.Secondly,the functional unit model is established and the functional modules are divided.Then the symbiotic system evolution of three harvesting functional modules was carried out.Finally,based on the principle of adaptability,the symbiotic layout of the modules is determined.In the phase of symbiotic design between silage machinery modules,the main working parameters of silage machinery are firstly determined.Secondly,optimize the transmission system of each module to ensure that the machine will not idle and material blocking.Then optimize the design of auxiliary symbiosis device between modules,determine the optimal fillet radius of the feeding barrel device,design the expansion device used to install the adjusting bundling device,design the lifting device used to install the adjusting coating device.Finally,modal analysis and optimization of the module frame are carried out to ensure the stability of the machine.Finally,the overall design scheme of silage machinery is obtained through this method.After the design scheme in Feicheng Farmers happy machinery factory for prototype production,and prototype test to verify the feasibility of the scheme.Due to the outbreak of the epidemic and in the non-harvest season,the experiment was carried out by replacing green corn straw with dry yellow corn straw.The prototype test mainly tests the operation of each functional module and the operation parameters of the whole machine.The test results show that all parameters meet the data requirements,which proves the feasibility of the design scheme and the universality of the modular symbiotic design method based on TRIZ theory.
