在室内土槽中对13种不同结构参数的全方位深松部件的土壤阻力和碎土质量进行了试验测定。经分析提出,全方位深松部件的合理结构参数为水平刀起土角30°,侧刀切土角25°,侧刀在横垂面内的倾角45°,侧刀在纵垂面内的后倾角30°;水平刀与左、右侧刀均采取下磨刃方式。侧刀切土角和侧刀在横垂面内的倾角对碎土效果有影响,但水平刀起土角、侧刀在纵垂面内的后倾角和水平刀长度对碎土效果没有影响。
The soil resistance and soil quality of all-round subsoiling parts with 13 different structural parameters were tested in an indoor soil tank. According to the analysis, the reasonable structural parameters of all-round subsoiler components are: 30 ° for horizontal cutter, 25 ° for side knife cutting, 45 ° for side knife in horizontal cross-section, After the inclination of 30 °; horizontal knife and the left and right knife are taken under the grinding way. The side cutter angle and the side cutter angle in the vertical plane have an impact on the crushing effect. However, the horizontal cutter angle, the side cutter in the vertical plane and the horizontal cutter length have no effect on the crushing effect.
