Most vegetable production adopts the technology of seedling nursing, but the vegetable transplanter in our country develops slowly and vegetable transplanting is mainly by manual work for a long time. It has seriously hampered the development of vegetable industry in China. So it has become an urgent issue to achieve seedling transplanting mechanization for our vegetable industry. According to the actual situation of Chinese vegetable production, based on the analysis of domestic and foreign transplanter’s general situations, development trends and characteristics of existing models, a new cantilever cup vegetable transplanter is designed and manufactured. It uses a cantilever cup planting apparatus as the key component to load and plant seedlings. To solve the problem that the hanging basket transplanter is apt to impact the seedlings when the seedlings are too high，the cantilever cup vegetable transplanter was designed．The structure and the working principle of whole machine were introduced，and the detailed structure of key components was designed． By using the cantilever cup which splays in the horizontal plane and opens backwards，the rate of damaged seedlings in the process of dropping seedlings was reduced and the whole machine’S planting quality was improved．Because of its cantilever cup opening backwards in the horizontal plane, so when the vegetable transplanter works under the situation of of characteristic coefficients, the opening cup leaves the seedling from the side along whole machine’s forward direction, which effectively solve the problem that the existing hanging basket transplanter is apt to impact the seedlings when the seedlings are too high. Based on the theoretical analysis, the overall configuration of cantilever cup vegetable transplanter and the specific structure of transplanting unit, transmission system, suspension frame, depth wheel, and ground wheel were determined. Three-dimensional model of the machine was established by 3D design software SolidWorks and did the interference checking. Key words：vegetable transplanter；cantilever cup；planting apparatus 目錄 摘要 1 Abstract 2 前言 3 1 蔬菜移栽機(jī)的研究發(fā)展 3 1.1國外移栽機(jī)械的研究概況 3 1.2國內(nèi)移栽機(jī)械的研究概況 3 1.3移栽機(jī)械的主要類型 4 1.4移栽機(jī)械研究存在的問題及發(fā)展趨勢 9 1.4.1移栽機(jī)械研究存在的問題 9 1.4.2移栽機(jī)械研究的發(fā)展趨勢 9 2 懸杯式蔬菜移栽機(jī)的工作機(jī)理 10 2.1栽苗器整體的運(yùn)動軌跡分析 10 2.1.1栽苗器整體的運(yùn)動方程 10 2.1.2栽苗器的運(yùn)動軌跡分析 11 2.2懸杯式蔬菜移栽機(jī)的主要特征參數(shù) 12 3懸杯式蔬菜移栽機(jī)的結(jié)構(gòu)設(shè)計(jì) 14 3.1整機(jī)結(jié)構(gòu)與工作過程 14 3.1.1整機(jī)結(jié)構(gòu) 14 3.1.2整機(jī)工作過程 15 3.1.3性能指標(biāo) 15 3.2栽植單體的設(shè)計(jì) 16 3.2.1栽植輪 16 3.2.2懸杯式栽苗器 18 3.2.3開溝器 23 3.2.4覆土鎮(zhèn)壓輪 23 3.3傳動系統(tǒng) 24 3.4懸掛裝置與機(jī)架 25 3.5限深輪 26 3.6地輪 27 4結(jié)論 28 參考文獻(xiàn) 28 致 謝 30 3
