A useful model is applicable to the field of agricultural machinery manufacturing, especially the working mechanism for planting steam tillage crops.;The device contains a spring - shaped working organ The spring axis bends 180 ° along the circular arc and tilts to the opposite position at an angle to the horizontal planeLateral descent. The spring is fixed on the frame and can rotate freely around the axis. One end of the spring is connected to the drive.Let it spin,Contrary to the forward movement of the unit in the ground contact area,The difference isHalf of the spring has a left winding,The other half (II) is right winding.;Therefore, when the device passes through the row of intercropping crops, the soil on both sides of the trench is raked evenly, This can improve the cultivation quality of crops.
