Experiment of collecting performance of vibration Camellia oleifera fruit harvester
摘要
Abstract
Camellia oleifera mainly grows in the high mountains and hilly areas of the subtropical regions in Southern China.It is a unique kind of pure natural high-grade oil in China.In recent years,the scientific researchers in China have conducted a large amount of research on the picking equipment of C.oleifera fruits,and different picking equipment of C.oleifera fruit with various picking methods such as vibration,comb-tooth,and patting have emerged.However,there is limited research on the collection equipment of C.oleifera fruits.The collision characteristics of C.oleifera fruits have great significance for the design and optimization of the collection equipment.To establish the collision model of C.oleifera fruits in the collecting umbrella and conveying mechanism,a test device for the recovery coefficient of C.oleifera fruits was constructed based on the principle of specular reflection and kinematics,and the elastic characteristics of C.oleifera fruit were measured and analyzed.An orthogonal experiment was conducted to determine the collision characteristics of large fruit C.oleifera varieties planted in Liuyang City,Hunan Province,China.The results showed that the primary and secondary order of factors affecting the collision restitution coefficient of C.oleifera fruit were material,collision angle,pulling force and falling height,among which the material was extremely significant,and the collision angle and pulling force were more significant than other two.In order to study the collecting performance of the C.oleifera fruit harvester,the collecting mechanism was simplified,and the effects of different materials,angles,and pull force on the collection rate of C.oleifera fruit were studied.The results of the orthogonal test of collecting performance showed that the material had the greatest impact on the collection rate of C.oleifera fruits,the angle affected the minimum horizontal motion distance of C.oleifera fruits,and the pulling force affected the maximum horizontal motion distance of C.oleifera fruits.When the material was oil cloth,the collision angle was 20°,and the pulling force was 60 N,the collection rate was 95.33%,and the collection effect was the best.The research results can provide a reference for the optimization design of key components of the collecting and conveying device of the C.oleifera fruit harvester.关键词
