Abstract
In view of the high labor intensity of sweet potato vine removal and harvesting,and the existing hilly sweet potato harvester generally has the problems of large excavation resistance,more power consumption,messy shape and low safety.Firstly,AHP and entropy weight method were used to obtain the comprehensive weight of user needs to determine the design focus.Secondly,the AD theory was used to complete the mapping of the user domain,functional domain and structural domain of the sweet potato harvester,and the design parameter sets such as the imitation ridge-shaped crushing knife roller assembly mechanism,soil scraping mechanism,and soil breaking and excavation mechanism were obtained.Finally,the TRIZ theory is used to resolve the contradictions and conflicts in the mapping process and realize the optimal design of the product structure.The harvesting equipment suitable for hilly hills integrates sweet potato vine removal and excavation.The theoretical integration method of AHP,AD and TRIZ effectively overcomes the contradiction between user needs and product function and structural design in the improvement design of agricultural machinery and equipment,so as to obtain a reasonable improvement design scheme of sweet potato vine removal and excavator,and at the same time provides a feasible idea for the further design of hilly sweet potato harvesting equipment.关键词
