Innovation Design Of The Suction Grain Sampler Based On TRIZ Theory

The suction grain sampler is an important equipment for carrying out deep sampling inside the granary.With the popularization of hybrid rice cultivation in various provinces of China,the grain output is showing a good trend.Under the current state control strictly over construction land conditions,grain warehousing companies still increase the number of granaries in order to meet the demand for grain storage,and further increase the height of the granaries on the basis of the original ancestors.The original suction type sampler can no longer meet the needs of the existing market.In order to meet the current deep grain sampling needs after the increase of the grain store height,based on the original suction grain sampler put into low cost in the short term to improve the existing suction grain sampler increase the sample depth and sample efficiency,has become the most important issue facing grain storage companies.The TRIZ theory is a systematic and innovative method,it has a complete set of tools from the analysis of innovation problems to corresponding solutions based on the types of problems,which can solve a variety of innovative technical problems encountered in the process of product innovation.Patent analysis can help companies capture the development trend of products and help companies formulate corresponding development plans to increase their competitiveness in the industry and maintain their advantages in the market.This paper uses the patent to analyze the development trend of the grain sampler industry,and according to the current grain storage companies face the problem that the existing suction grain sampler with sampling depth not enough and the sampling efficiency is low,applied the TRIZ theory improve the existing suction grain sampler to improve the sample depth and improve the sample efficiency.In this paper,the patent technology life cycle combined with the patent sample data analysis was first applied to determine preliminarily the technology life cycle and research trends of the grain sample,and based on TRIZ causal chain to analyze the impact of the reason of the sample efficiency.According to the results of the preliminary causal analysis,the results of the preliminary causal analysis confirmed that the suction pipe,the system connection structure,and the sample collection device in the suction type grain sampler were the innovations and improvement object,and by improving suction pipe,the system connection structure,and the sample collection device of the suction type grain sampler to increase the sample depth and enhance the sample efficiency;Then,for the low efficiency caused by the insufficient sampling depth of the suction type grain sampler caused by the sampling tube structure,the causal chain analysis was used to find out the root cause of defects in the sampling tube structure,and the existing technology and knowledge were used to select the causal chain analysis.Influencing factors Construct the TRIZ conflict model,apply the TRIZ conflict resolution process to solve the contradictions caused by various influencing factors;and then apply the TRIZ causal chain to analyze the problem of low sample efficiency due to the tightness of the suction grain sampler connection structure.The root cause and function analysis of system connection leaks determine the existence of under-connected components and harmful functions in the system,and establish the corresponding contradictory problem model and substance-field model for the inadequacy of the connection structure of the system connection structure due to different causes,applying the TRIZ theory tool to solve the problem;Finally,with regard to the problem of low sample efficiency due to the structure design of the sample bucket of the sampling device for the sample suction device for grain sampling,the resource analysis of the suction grain sampler was performed using the TRIZ theoretical resource analysis,and the sampling tank was selected as the system for functional analysis and trimming design,the secondary contradiction caused by trimming design combined with the technological evolution life cycle and the TRIZ technical evolution theory use the corresponding evolution rule to solve the secondary contradiction caused by trimming design.Based on the TRIZ theory to improve the existing suction type grain sampler’s manifold,system connection structure,and sample collection device,which could be further applied to other relevant products in this industry’s industry,enabling rapid iteration and sustainable and efficient innovation of products.
