摘  要：
针对大蒜联合收获机设计时缺乏必要的数据支持等问题,对成熟期大蒜茎秆力学特性进行了试验研究。采用农业田间数理统计方法对大蒜的几何特征进行分析,得出了大蒜主要几何特性指标值的变化区间和分布频率;利用万能试验机及拉伸试验对成熟期大蒜茎秆抗拉强度、挤压强度、起拔力等力学特性进行测试,研究了茎秆直茎、含水率、加载速度对大蒜茎秆拉断力的影响;应用Design-Expert软件分析,得出了松土位置参数优化组合。结果表明:直径对大蒜茎秆的拉断力影响最大,其次是含水率,最后是加载速度;大蒜最小起拔力的最优组合为挖掘深度9~18cm和挖掘距离2~10cm,所需起拔力小于53.1N,不会发生漏收现象;大蒜茎秆的挤压强度平均值是0.78MPa,所以在设计皮带夹持过程中挤压强度最大不能超过0.72MPa,为研制大蒜联合收获机关键装备提供了基础理论依据。

摘  要：
In view of the lack of necessary data support for the design of garlic combine harvester,this paper aims to research 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 9-18 cm and excavation distance of 2-10 cm,the required pull force is less than 53. 1 N,no leakage phenomenon. Garlic stem extrusion strength average is 0. 78 MPa,so in the design of the belt clamping process,the maximum extrusion strength can not exceed 0. 72 MPa,which provided the basic theoretical basis for developing the key equipment of garlic combine harvester.
