对一些有特殊要求的农场来说,耕作机具牵引需求数据的有效性对于选择适当的耕作机具是极为重要的。机具宽度、作业深度、前进速度、土壤情况和机具机型都影响着机具的牵引。利用放置在砂壤土中的数字荷重单元对不同前进速度(0.69、1.11和1.52 ms)和耕作深度(100、150和200 mm),两种主要耕作机械牵引的影响进行了研究。采用的工具包括3个底圆盘犁和2个底型铧式犁。在两种方案中,速度和深度都随着工具牵引增加而增加。所有的工具牵引对深度的影响大于对速度的影响。在所有的前进速度和耕作深度的处理中,铧式犁的测量值均大于圆盘犁。基于速度和深度,对两种特殊牵引模拟了一般回归方程。
For some farms with special requirements, the availability of tillage implement pull demand data is extremely important for the selection of the appropriate tillage implement. Machine width, depth of operation, speed of advance, soil conditions and machine models all affect the traction of the machine. The effects of two main tillage machines on traction were studied using digital load cells placed in sandy loam at different speeds of advance (0.69, 1.11 and 1.52 ms) and tillage depths (100, 150 and 200 mm). The tools used included three bottom disc plows and two bottom plowshares. In both scenarios, the speed and depth increase as the tooling increases. All tool traction has greater impact on depth than on speed. Plow measurements were greater for plows than for disc plows at all forward speeds and tillage depths. Based on velocity and depth, the general regression equation was simulated for two special traction.
