1收割机的选型与调整油菜籽机械化收获就是利用水稻联合收割机收割,集收割、脱粒、清选、装袋作业一次性完成。由于油菜的植株比水稻高,茎杆直径是水稻杆的5～15倍,不容易切断。因此,要对收割机进行技术改进:加长割台,降低拨禾轮转速,分禾器改装,筛面更换等。但收割机改进需要增加约5000元费用,机手和农民难以接受。
1 harvester selection and adjustment rapeseed mechanization harvest is the use of rice combine harvester harvest, harvesting, threshing, cleaning, bagging operations done in one go. Because rape plants are taller than rice, the diameter of the stalk is 5 to 15 times the diameter of the rice stalk, which is not easily cut. Therefore, the harvester to make technical improvements: longer header, reduce the reel speed, dividend modification, screen surface replacement. However, the improvement of harvesters need to increase the cost of about 5,000 yuan, the hands and farmers unacceptable.
