成熟期大蒜茎秆力学特性的试验研究
Experimental Research on Mechanical Properties of GarlicIn Mature Period
摘要
Abstract
In view of the lack of necessary data support for the design of garlic combine harvester,this paper aims to re-search the mechanical properties of garlic in mature period.The geometric characteristics of garlic were analyzed by means of mathematical statistics in agricultural field,and the range and frequency of the main geometric characteristics of garlic were obtained;To test the maturity of garlic stalks tensile strength, compressive strength, pulling force of mechanical properties by using universal testing machine and tensile experiment, studied the effect of stem straight stems, moisture content, loading rate on the tensile force.Design-Expert software analysis was used to get the optimum combination of soil position parameters,which provided the basic theoretical basis for developing the key equipment of garlic combine harvester.The results show that the tensile strength of garlic stem diameter of the biggest influence, followed by water content,finally loading speed;The optimum combination of garlic minimum pulling force is excavation depth of 9-18cm and excavation distance of 2-10cm,the required pull force is less than 53.1N,no leakage phenomenon.Garlic stem ex-trusion strength average is 0.78MPa,so in the design of the belt clamping process,the maximum extrusion strength can not exceed 0.72MPa,which provided the basic theoretical basis for developing the key equipment of garlic combine har -vester.关键词
