现在作为深耕时加深耕层之鬆土铲在农业机械学,机制百科全书,及大专学校的教科书都介绍的是标准化的双翼铲,只不过有几种不同的工作宽度,而现有深耕犂则有的国家用双翼、有的用单翼,在我院对畜力深耕犂的试验研究过程中,我们用了华东农科所的双翼铲(宽18cm)和双铧犂犁铲(单翼铲)作了比较,从多次记录中看出,在同样工作宽度时,单翼比双翼拉力轻20～30%,性能也好,我们建议各
Now, as a shovel for deepening deep plowing during deep plowing, textbooks on agricultural mechanics, encyclopaedias of machinery, and tertiary schools all introduce standardized shovels with only a few different working widths, whereas the existing deep plow In some countries, we used two shovel wings (width 18 cm) and double-plow plow shovels (one wing shovel) in the experimental study of deep plowing in our hospital with wings and some with wings. Made a comparison, seen from many records, at the same working width, wing 20 ~ 30% lighter than the bicep, the performance is good, we suggest that each
