可调地隙采摘式菠萝运输车底盘的设计与研究

Design and Research of Chassis of Pineapple Transporter with Plucking and Adjustable Ground Clearance

目前,我国的菠萝的采收与运输主要以人工为主,缺乏机械化,生产效率低,人工成本较高。为此,研制了一款可调地隙采摘式菠萝运输车,并基于实地调研资料,设计了新式的车架与车厢结构,使运输车适应于菠萝种植业作业需求。采用Solid Works进行三维建模,并进行运动仿真,利用Solid Works Simulation软件对车横梁、车架、升降机构等进行有限元受力分析,校核设计机构的合理性,优化设计结构。本产品关键技术为采用了剪叉式液压升降结构,可满足离地间隙可调的性能要求,并采用汽油发电机混合动力提供行驶动力,简化了传动机构且降低了油耗。

At present,the harvest and transportation of pineapple in China are mainly depengding on artificial labor,which lacks mechanization,leading to the low production efficiency and the high labor cost. In order to promote the development of Chinese pineapple industry,realize the mechanization of the pineapple planting industry,improve the efficiency of pineapple transportation as well as reduce the orchardist's laboring intensity,our team designed a type of pineapple transporter with plucking and adjustable to gap. Based on the field investigation data,we designed a kind of new frame and new carriage structure to make the transporter meet the need of pineapple planting industry. With Solid Works3 d modeling and motion simulation,using Solid Works Simulation software to study the car beam,frame and lifting mechanism by finite element stress method,we check the rationality of the design and optimize organization structure of the design. The pivotal technology is using hydraulic scissor lift structure to meet the need of adjustable ground clearance of pineapple transporter,and using gasoline- electric hybrid provides driving force in order to simplify the transmission and reduce the fuel consumption.
