Research On Innovative Design Of Leek Harvester Based On Situation

With the deepening and advancement of my country’s modern agricultural machinery,crop harvesting and mechanization have gradually become an important part of my country’s agricultural production that cannot be ignored.Due to the fact that crops and vegetables in our country have the characteristics of strong seasonality,tight time,heavy tasks,and susceptibility to rain,snow,wind,and frost,the popularization of mechanization has become particularly urgent.Judging from the current harvesting techniques for leeks,almost all of them are harvested manually,which is time-consuming,exhausting,and slow.Therefore,manual harvesting has always restricted the vigorous development of leek brand cultivation.Since all the leek harvesters on the market only realize the function of cutting leek,their form is relatively simple and does not reduce the labor intensity for laborers.Therefore,it is urgent to design a leek harvester that integrates cutting and bundling.solved problem.In this paper,aiming at the harvesting unit,conveying unit and bundling unit of the leek harvester,using principal component analysis,analytic hierarchy process,product function analysis,triangular fuzzy number and other methods,the existing leek harvester and related harvesting equipment On the basis of this,an innovative design research was carried out on the overall function of the leek harvester.First,based on the relevant information obtained from the related information of the leek harvester,a scenario story board was constructed to obtain the original needs of the user from the actual scenario.Use the KJ method to sort out and refine,summarize and screen to obtain independent user needs;apply principal component analysis to perform dynamic clustering to obtain hierarchical user needs;apply analytic hierarchy process to quantify the importance of multi-level user needs indicators,and establish users Demand model.Secondly,through the functional principle analysis method,the function and structure principle of related typical products are systematically analyzed,the functional principle structure of each product is obtained,the functional principle structure of each product is obtained,and the function of the leek harvester is integrated in the form of a function tree.The functional principle structure diagram of the leek harvester is established,and the functional principle is solved by the morphological matrix,and the output of the functional principle scheme is realized.Finally,the construction of the evaluation index system of the product function principle scheme is realized,and the best scheme is selected according to the relevant application such as analytic hierarchy process and the evaluation index score and decision-making.Using Rhino and Key-shot software,the three-dimensional model construction and appearance expression of the functional principle scheme of the leek harvester are realized.The implementation process of the product function innovation scheme is simulated through situational simulation,and the user demand model is combined again to conduct a comprehensive demand satisfaction evaluation of the final design scheme,and evaluate the effectiveness and feasibility of the scheme.This method proposes a more feasible scheme for the design of the leek harvester,and also provides a reference basis for other types of harvesters.
