一、旋耕机近年来,在苏联推广一种被称作土壤旋耕机的整地机。它的基本工作装置是一个装有刀片的辊子(图1),辊子由拖拉机的发动机来带动。机器运转时,辊子上的刀片连续不断地按规定的深度将土壤打碎,并向后抛去。这样把土壤打碎和搅拌,旋耕机通过以后,土壤不再需要任何的辅助加工。 First, rotary cultivator In recent years, in the Soviet Union to promote a known as soil rotary cultivator machine. Its basic working unit is a blade-mounted roller (Figure 1) driven by the tractor’s engine. When the machine is running, the blades on the rollers break the soil continuously and at a specified depth and throw it backwards. This smashes and agitates the soil so that the soil does not require any additional processing after it has passed.
