Rotary knife axis is mutually perpendicular to rotary cultivator direction of advance so that rotary blade during advance be easy winding field weeds and
Sundries needs artificially to cut off and remove twining grass, causes operating personnel's labor when twining careless quantity excessively influences rotary blade normal work
Fatigue resistance is big, while reducing soil cultivation efficiency.The second is existing rotary blade this reaction force of farming marshy land relatively
When small soil, the reaction force that rotary blade generates is so small that will to generate when enough dragger devices do not move ahead and get deeply stuck in, once occurring
It gets deeply stuck in and has nothing for it in addition to manually suing and labouring, and small part is equipped with the rotary cultivator of the traction mechanisms such as traction wheel, the axis of rotary blade
Horizontally disposed along direction of advance, traction wheel is also easily trapped into rotten ground or deep paddy field, since its rotary blade can not be rotary cultivator
Upward liter lifting force is provided, therefore, when traction wheel is got deeply stuck in, can only also rely on and manually sue and labour.
Therefore, in order to solve the above problem, a kind of wetland Rotary tillage blade is needed, helical blade is provided on the blade, can have
Effect avoids rotary cultivator from getting deeply stuck in farming marshy land, deep paddy field.
Summary of the invention
In view of this, providing a kind of wetland Rotary tillage blade, the knife the purpose of the present invention is overcoming defect in the prior art
On piece is provided with helical blade, can effectively avoid rotary cultivator and gets deeply stuck in farming marshy land, deep paddy field.
