雜交水稻籽粒分選清選機械裝備設(shè)計

摘  要:雜交水稻工程化制種改變了以前雜交水稻母本于父本間行種植的方式，采用母本與父本混合種植的方式，這就造成了收獲后的種子既有母本又有父本；通過實驗研究分析可得，母本籽粒的長度約6mm左右，而父本籽粒大約11-12mm，根據(jù)兩種籽粒的長度的特性的不同，擬設(shè)計以窩眼滾輪筒為主要工作部件的清洗機來清選出所需要的母本籽粒。本設(shè)計根據(jù)當前社會發(fā)展需要，自行設(shè)計了窩眼滾輪筒，介紹了窩眼滾輪筒國內(nèi)外研究情況和研究意義。本窩眼滾輪筒重點對分選筒內(nèi)籽的運動動力學分析，得出了影響籽粒分選的主要因素窩眼分選筒的直徑、角速度及斜置傾角，設(shè)計計算了各主要部件所需參數(shù)并進行了校核，完成了裝備圖及各主要零件的圖紙設(shè)計，進行了自我總結(jié)。

Design Of Grain Scalping Machine

Abstract: Hybrid Rice Seed Production of Hybrid Rice changed the previous inter-row cultivation of the female parent in the way male, female and male parent by way of mixed cultivation, which resulted in the seeds after harvest have both male female parent;analysis can be obtained through experiment, the grain length of about 6mm female parent, while the male seed of about 11-12mm, according to the characteristics of the two grains of different length, to be designed to nest eye roller tube as the main working parts of the washing machine?required to settle the election of the female parent grain.The design based on the current social development, to design a roller tube eye socket, eye socket roller tube introduced the situation and significance of domestic and international research.?The roller tube nest eyes focus on the movement of seed tube sorting dynamic analysis of grains obtained the main factor separating the eye socket diameter tube sorting, angular and oblique angle, design and calculation of the major components required?parameters were checked, completed the plans and major parts and equipment design drawings, were self-summary.
