带翼深松铲的试验研究

Experimental Study on a Type of Subsoiling Shovel with Flank

通过深松铲在南方砂壤土的深松试验,研究带翼深松铲和不带侧翼深松铲的耕作阻力及深松后的土壤剖面。结果表明,深松铲前进方向的阻力随安装角的增加而加大,由于深松铲侧翼的宽度比铲头宽,使土壤内部形成分层构造,扩大深松铲的松土范围,同时提高土壤的保墒蓄水能力。

In the study,experiments of subsoiling shovels working under sandy loam soil in Southern China were done,tillage resistance of shovels with flank wing and without flank wing and profile of soil after subsoling were researched.Results showed that with the increase of subsoiling shovels＇ install angle,their resistance along advancing direction increased.And as the width of flank wing was larger than the shovel head,layered structure was formed after subsoiling,enlarging subsoiling scope of shovels and improving the soil＇s capability of moisture conservation.
