土豆采摘装置结构设计

Structure dseign of potato picking deviceAbstractWith the rapid development of mechanical industry,various kinds of equipment havebeen developed and used in production and life to provide convenience for people's life.China is a large agricultural country,and the planting area of agricultural products isrelatively large.The planting area of potatoes is up to 150 million,which is the largest inthe world at present.The area is 8%of the cultivated land in China.And the domestic potatooutput is also the first in the world,with an annual output of 90 million tons.Potatoes arewidely used and have a large output value,which is one of many agricultural products.Sucha huge output of potato harvesting,the workload is very large,especially in the harvestseason every year,the time is relatively compact,the traditional way is mostly manualharvesting,this way is a way that has continued from ancient times to the present,there arelow efficiency problems,so it is suitable for some small farmers in rural areas,for largeplanting bases and potato production enterprises Say.The annual output is relatively large,if only relying on manual picking,it can not meet the requirements of large-scale receiving,and the current labor cost is increasing year by year,for the production unit,it isundoubtedly facing huge economic pressure,so it is urgent to use agricultural machineryinstead of traditional manual operation,to change the labor-intensive production of theproduction and planting enterprises into automatic production of cost machines Increase theproduction capacity and efficiency of the enterprise by a large margin and reduce the laborcost.This design of the potato picker device,mainly for potato harvesting equipment.Through the market investigation and analysis,and query the knowledge of related books,the potato picker program is determined.Through the analysis of potato size,determine thebucket clearance,at the same time,determine the transmission mechanism scheme,makethe corresponding calculation of chain drive,as well as the design and verification oftransmission shaft,the design of key and bearing,etc.And draw the drawing of the potatopicker by CAD software.Key words:Potato picker,scheme determination,chain drive,design check
