Optimal Design Of Silage Equipment Baling Device Based On Disruptive Innovation Theory

China is a large agricultural province rich in straw resources,but 42 % of the straw has not been effectively utilized.Shandong province is also a big animal husbandry province.The increase of feed grain poses a certain threat to China ’ s food security.The cultivated land area in hilly and mountainous areas of Shandong Province is also prominent,and the supply of agricultural machinery and equipment suitable for hilly and mountainous areas is seriously insufficient.Therefore,the development of small and medium-sized silage equipment is the only way for the development of silage machinery in China.Since the reform and opening up,the ecological environment has been deteriorating.Agricultural machinery exhibits material and energy waste,inconvenient recovery and poor performance,especially silage machinery.In addition,the market is fiercely competitive.Designers need innovative and logical methods to guide product design.This paper combines the TRIZ theory with the WBCSD ecoefficiency factors,and summarizes the ecological design method model based on the innovative method theory.It improves the ecological performance of the product while meeting the functional requirements of the product.This paper summarizes the optimization design process based on disruptive innovation theory through the comprehensive utilization of product technology maturity prediction and user research methods combined with the corresponding relationship between disruptive innovation strategy and engineering parameters and TRIZ problem solving tools.Under the premise of meeting the needs of users,the product can be designed to reduce the dimension and cost of the product,so that the cost of the product is lower,the operation is simpler and the volume is lighter,so that it is favored by users.This can not only effectively solve the problems existing in the current silage equipment bundling device,but also make the silage equipment bundling device have the characteristics of simpler structure,smaller size and cheaper price.In this paper,the silage equipment of the R & D and innovation program of agricultural machinery equipment in Shandong Province is taken as the research object.Through the decomposition of the system function of the silage equipment,the modular structure layout of the whole machine and the destructive innovation design of the key components of the baling device are carried out.The demand evolution law in TRIZ theory is used to analyze the current situation of the baling device of the silage machine and determine the needs of the users.Through the selection of destructive innovation strategies,the functional system problems are found and the parameters that need to be optimized for the baling device are determined.Then,guided by the destructive innovation theory,the overall structure layout of the silage equipment and the optimization design of the key components of the baling device are carried out.Then use the conflict resolution principle to solve the conflict contradictions encountered in the design process.The destructive innovation research is carried out on the rope winding mechanism,the rope cutting mechanism,the pressure bin,the collection box and the conveying mechanism.The key parameters of the above mechanism are selected and calculated through the selection of strategies and the principle of parameter optimization,and then the optimized structure of destructive innovation is obtained by using the principle of conflict resolution.The modeling of the baling device and the simulation analysis of the optimized mechanism are carried out.The simulation results show that the stress deformation and displacement of the mechanism are improved.Finally,the prototype is trial-produced and tested to test the reliability of the prototype and whether the collected relevant data meet the technical indicators.It is verified that the design process based on disruptive innovation theory can optimize the silage equipment reliably.
