两段式花生摘果特性试验研究
Study on Properties of Two-step Type Peanut Stripping
摘要
Abstract
In order to prove properties of peanut stripping of two stage harvesting conditions , improve the quality of pea-nut combine harvester .In this paper , the types of Tianfu 9 in Suqian , Jiangsu Province were regarded as test materials . Based on the method of combining field experiment with laboratory , the electronic universal testing machine , 4 HJL-8 type peanut combine harvester and other equipment were applied to study on the main factors influencing the properties of fruit stripping at harvest period , and reveal internal relation among moisture percentage of peanut , drying time , mechani-cal properties of stalk and quality of fruit stripping .The results show that the breaking force of peanut stalk varies with different test conditions , but change trend is consistent with drying time ( moisture percentage ) and stipe tensile force reached its peak during the time of previous 2-3 days after digging .The result also shows that stem root node is greater than the tensile strength of root nut node .From the point of increasing the quality of peanut stripping , it was put forward that the most suitable time for mechanical stripping up was about 5-6 days after sunning , which was tested by the peanut combine harvester .The above results provide the direct basis for structure and motion parameters of peanut stripping de -vice , and provide the necessary reference for best stripping time of two-stage harvesting type , as well as deeply research peanut stripping efficiency and stripping loss .关键词
