【摘要】 插秧是水稻种植体系中的重要环节之一。近年来,人工插秧与运输秧苗等作业环节易造成劳动强度大、效率低等问题,使得人们对这些环节高效率、智能化的需求愈加迫切。为此,设计了一种结构简单、操作简便、能快速变轨且性价比高的轨道式水稻秧苗运输车。运输车采用SMC薄型液压缸,主要作用是升降轨道;采用奥普特SCI-Q2视觉控制器,可对轨道上的杂物进行识别;采用德马克生产的直流伺服电机,尺寸42mm,功率100W,电压24V,转速0～8000r/min,主要驱动运输车运行。利用SolidWorks软件对秧苗运输车完成三维结构建模,并用Simulation对主要部位进行空载与满载情况下的强度校核,验证其结构的可行性。所设计的轨道式水稻秧苗运输车可自主避障、智能变轨,使运输车往返于不同的轨道上,将秧苗送达插秧机附近,在提高插秧效率的同时降低了农民的劳动强度及水稻种植成本,从而达到水稻的全程机械化种植要求。更多还原

【Abstract】 Transplanting is one of the important links in the rice planting system. In recent years, manual transplanting and seedling transportation are easy to cause problems of high labor intensity and low efficiency, and people’s demand for its high efficiency and intelligence is becoming more and more urgent.This paper mainly designed a simple structure, simple operation, can quickly change the rail, high cost-performance rice seedling transport vehicle.The transporter adopts SMC thin hydraulic cylinder, whose main function is lifting track.The opte SCI-Q2 vision controller is adopted to identify the debris on the track.Dc servo motor produced by demark is adopted, with size of 42 mm, power of 100 W, voltage of 24 V and speed of 0-8000 r/min, mainly driving the transport vehicle.In this paper, SolidWorks software was used to complete the three-dimensional structure modeling of seedling transporter, and Simulation was used to check the strength of main parts under no-load and full-load conditions to verify the feasibility of its structure.In this paper, the design of rail type rice seedling transporter orbit autonomous obstacle avoidance, intelligence, make the truck from different orbit, deliver the seedlings to the transplanter,while improving the efficiency of transplanting rice, the labor intensity of farmers and the cost of rice planting were reduced, so as to meet the requirement of full mechanized rice planting.更多还原
