气动下压式高速取投苗装置与吊杯时空匹配关系研究
Limit of Synchronous Seedling Reaching of Pneumatic Ejecting Type High-speed Transplanter
摘要
Abstract
To explore a technology solution capable of achieving high-speed seedling retrieval followed by uninterrupted rapid seedling deployment and synchronized seedling reception,an analysis was conducted on the four-stage movement process of rapid seedling deployment after high-speed seedling retrieval by using a pneumatic down-press type high-speed seedling retrieval and deployment device,obtaining the movement time of tray seedlings.High-speed photography was used to capture the process of uninterrupted rapid seedling deployment by the research group's custom-built high-speed seedling retrieval and deployment device,with PCC software utilized for capture analysis and calculation,examining the relationship between displacement and time during the continuous seedling throw and deploy process.Through limit analysis and intersection operation of synchronous seedling reception,the range of advance phase angles for hanging cup synchronous seedling reception at different seedling retrieval frequencies was determined,achieving the spatio-temporal matching relationship between high-speed seedling retrieval and deployment device,high-speed seedling retrieval,uninterrupted rapid seedling deployment,and hanging cup synchronous seedling reception.Verification experiments of the hanging cup synchronous seedling reception effect were conducted on a high-speed transplanter prototype,with results showing a success rate of 96.4％for hanging cup synchronous seedling reception at a retrieval frequency of 180 seedlings/min,providing foundational data for the spatio-temporal matching relationship between the high-speed seedling retrieval and deployment device and the hanging cup.关键词
