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 continuously forming ridges in a field or the like.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Examined Patent Publication No. 5-9041 or Japanese Patent Laid-Open No. 61-192202, a ridge is formed by a shaping plate when soil is drawn by a rotary, and a shaping roller at the rear of the shaping plate. There was a technique to finish the surface of the ridge.

[0003]

In the above-mentioned prior art, since the shaping roller is always supported in a substantially constant posture with respect to the support member of the shaping plate, it is necessary to change the amount of earthing of the rotary or the nature of the soil forming the ridge. Regardless of this, the static pressing action of the shaping roller becomes almost constant, insufficient ridge tightening in dry fields, and surface peeling or craters (partial depressions) easily occur due to clay ridges, improving the finishing accuracy of ridges. There was a problem that it could not be improved easily.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention provides a ridge coating device for forming soil by a rotary to form ridges by a shaping plate and finishing the ridge surface by a shaping roller at the rear of the shaping plate. A bearing member that is rotatable around the longitudinal axis of the support member is attached to the support member of (1) via an elevating member, and the shaping roller is provided on the bearing member.
Since the shaping roller is supported by the lifting member so that it can be raised and lowered, the static pressing action of the shaping roller can be easily adapted to changes in the amount of soil soiling of the rotary or the nature of the soil forming the ridges, and insufficient tightening in dry fields. In addition, it is possible to easily prevent surface peeling or crater generation on clay ridges, and since the bearing member supports the shaping roller rotatably around the longitudinal axis, it is shaped by tilting the machine horizontally. The roller can eliminate problems such as partial tightening of the ridges and inclination of the ridge surface, and the finishing accuracy of the ridges can be easily improved.
