Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge coating device for mechanically producing ridges in a paddy field.

[0002]

2. Description of the Related Art In this type of ridge coating machine, a parallel link integrally supporting a vibrator with a ridge shaping plate is provided so as to move parallel to the ridge slope.

[0003]

However, in the case of the conventional means as described above, the upper surface of the ridge is satisfactorily followed by strong compaction, whereas the ridge has a followability with respect to the slope side. It has a defect that it becomes bad and the compaction is not sufficiently performed, and when an overload in the direction perpendicular to the slope is applied, the ridge shaping plate or the like is deformed or damaged.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in a structure in which a vibrator for oscillating a ridge shaping plate is movably supported on a body via a parallel link, the parallel link is provided in a direction substantially perpendicular to a ridge slope. In addition to being rotatably provided, one of the parallel links is provided so as to be movable in a direction substantially along the slope of the ridge, thereby improving the followability of the orthopedic plate to both the slope and the upper face of the ridge. A strong ridge is made by applying a strong compaction force to the ridge, and even if an overload is applied from any of these, a parallel link is used without causing any abnormality in the ridge shaping plate or the vibrator suspension spring. It is possible to avoid these and to protect them. In addition, by providing a balance spring on the link that can move in a direction that roughly follows the slope of the ridge,
The ability to follow the ridge upper surface side can be further improved, and the upper surface compaction force can be adjusted appropriately, so that the ridge can be made appropriately corresponding to various conditions and ridge shapes.
