理论研究的目的,是论证整地用各种工作装置在整地时的牵引阻力达到最小化的配置次序。在中耕机上配置工作装置可有3种方案,在中耕机的各排上安装箭型中耕铲;在第一排安装深松铲,第二排安装箭型中耕铲;在第一排安装箭型中耕铲,在第二排安装深松铲。研究表明,在中耕机第一排安装箭型中耕铲为最佳方案,因为在农机允许速度(2.22~3.33m/s)范围内,其牵引阻力比在第一排安装深松铲的中耕机牵引阻力低17%～21%。
The purpose of the theoretical study is to demonstrate the order of arrangement for minimizing the drag resistance during land preparation with various working equipment for site preparation. There are three options to configure the working device on the cultivator, install the arrow tillage shovel on each row of the cultivator, install the deep shovel shovel on the first row, install the arrow tillage shovel on the second row, install the arrow type Cultivation shovel, in the second row to install deep shovel. The research shows that the best option is to install arrow tillage shovels in the first row of cultivator because the towing resistance is higher than the tillage cultivator with the deep shovel in the first row in the allowable speed of agricultural machinery (2.22 ~ 3.33m / s) Traction resistance low 17% ~ 21%.
