Vertical shaft.
The working part is a rotary cultivator with 2 ~ 3 spiral cutters. During the operation, the rotary plougher rotates on a vertical axis and the cutter cuts up the soil. It is suitable for paddy field hydroploughing, with strong soil crushing and slurry function, but poor mulching performance. It is widely used in Japan.
In order to enhance the tillage effect of the rotary tiller, various additional devices are installed on the rotary tiller in some countries. If be in behind rotary tiller hang nail tooth rake in order to enhance broken earth action, add load loose earth shovel to deepen plough layer to wait.
The diagonal.
The rotary tillage working parts of the inclined rotary tiller are inclined in the horizontal plane. The rotary tillage knife's rotary plane is at a certain Angle with the forward direction of the machine -- the oblique Angle. When the rotary tillage blade cuts soil, it has a relative axial movement. The arrangement of single row rotary tillage blades on the cutter shaft is related to the forward speed of the unit, the rotary speed of the cutter roller and the width of the blade. There is a certain phase difference between two adjacent rotary blades on the same helix. Inclined rotary tiller works without heavy tillage, which removes soil constraints, thus reducing power consumption and tillage resistance.
