With a ridge forming device having a ridge body that is formed into ridges while rotating the mud supplied by, a ridge coater in which the ridge body is formed by a conical multi-sided drum,
For example, it is well known from JP 2001-161107 A. As shown in FIGS. 28 to 38, the conical polygonal drum a has an umbrella shape in which a central portion in the radial direction (center portion of the drum) is attached to a horizontal rotation shaft b so as to be eccentrically rotated in the rotation direction. In this case, the ridge line e is formed only by the step portion d or the boundary line in the radial direction to form the eight ridge surfaces c.

28-31, a conical multi-sided drum a
Attaches the drum to the rotating shaft b in an eccentric manner with respect to the rotation direction such that the center of the drum is offset from the axis of the rotating shaft b, and the ridge surface c has a lower front portion in the rotation (arrow) direction. , The rear part is inclined so as to be high, and when the drum a is rotated, the ridge surface c is arranged so that the front half of the radial direction is a non-contact surface with the soil and the rear half is a contact surface. I am trying. The ridge line e has a receding angle in the rotation direction and is linear.
