The unique profile structure of body, parallel with direction of advance all the time, upturned soil will not be produced upset, reduce soil and disturb
Dynamic, there is good technique effect.
The forming process of described working curved surface described in detail below:
Described leaning forward is cut soil curve MN and inclination and is lifted soil curve PQ and lay respectively at two orthogonal planes
In.
Lean forward cut soil curve MN along three-dimensional system of coordinate X-direction forward stretch formed curved surface lift with inclination
Soil curve PQ intersects at first in space along the curved surface of the Y direction forward stretching formation of three-dimensional system of coordinate
Curve EF.This first curve EF is the edge of shovel line of described bending-type plough body.
Finally by described first curve along Y direction, after negative sense extends predetermined width, i.e. available described
Working curved surface.
