摘    要:为了改进杆式除草器的入土性能并减少其牵引阻力,在实验室土槽内对四种不同形状的除草器的土壤反作用力进行了测试。本试验采用了裂区实验设计;土壤类型为主区,除草器的形状,转速、前进速度及耕深在小区内。实验数据是由一个计算机化六分力式数据采集系统采集的。在测试的四种形状中,十字形截面的除草器所受到的牵引阻力和垂直支反力最小,具有良好的入土性能,优于圆形、方形和三角形截面的除草器。

关 键 词:杆式除草器  牵引阻力  垂直支反力

Abstract:A rod weeder experiment was conducted in a laboratory soil for the purpose of improving the implement's penetration and reducing its draft. A split -plot experimental design was used with differing soil types in the main plots and differing rod shapes, travel speeds, rod speeds and tillage depths in the sub -plot. The data were collected by a computer based stationary six-cell dynamometer data acquisition system to measure the forces on the rod. Among the four types of rod tested, round, square, triangle and fluted rods, the fluted rod had the least draft and vertical reaction because its fluted shape and relatively smaller effective diameter lowered the plane of separation below which soil must be compacted and, in turn, reduced the compaction and used less energy.
Keywords:rod weeder  draft  vertical reaction force
