摘    要:针对玉米收获过程拨禾导向装置存在推倒植株而产生果穗漏摘严重的问题,从农机运用角度,分析了玉米收获的对行方式和拨指作用位置对植株推倒率的影响,结果表明,3行自走式玉米收获机采用中间对行结合提高拨指作用位置的收获方式,可以有效减少植株的推倒率,降低果穗的漏摘损失。对于摘辊间距为68?cm的收获机,在收获种植行距为55?cm的玉米时,采用中间对行收获可将边际行偏差由原来的26?cm降低到13?cm,进一步将拨指高度提高到40~45?cm时,可将植株推倒率降低到1%。

关 键 词:联合收获机,优化,试验,聚拢导向,拨禾链,推倒率,玉米

Abstract:Aimed to the problem of corn leakage picking, which was caused by raking and conveying device in the process of corn harvest, the influence of both the way of harvest in row and the height of raking finger on the plant down rate was studied in the paper. The results showed that the harvesting way combining the harvest in middle row with high raking location of raking finger could effectively decrease the plant down rate and reduce the spike leakage loss for 3-row of self-propelled corn harvester. The deviation between plant row and the snapping rolls of outside of corn harvester could be decreased from 26 to 13 cm when the harvester with group distance between snapping rolls of 68 cm was experimented on the row distance of corn plant of 55 cm, and the plant down rate could be further decreased to 1% when the raking finger height was up to 40-45cm .
Keywords:combines  experiments  optimization  raking and conveying device  conveying chain  plant broken rate  corn
