DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge coating apparatus for continuously forming ridges in a field or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open Publication No. 3-83003 , a ridge shaping plate is provided behind a rotary claw to vibrate.
There is a technology to form ridges by vibrating up and down with data .

[0003]

The above prior art is based on a ridge arrangement.
The entire shape plate is inclined from front to back and then to low, and the soil compaction part of the ridge shaping plate
The soil is taken directly from the front to the ridge shaping board.
Insufficient soil uptake and ridges that easily collapse
There is a condition. Also, disclosed in JP-A-61-28304.
In this way, the ridge shaping plate is formed in a step-like manner with
There is also technology to compact the soil, but it is better to take in the soil at the front.
By doing well, the stair-like height difference of the ridge shaping board will vibrate.
And pushes mud forward.
And the stair-like height difference of the ridge shaping board is small.
Prevents mud pushing by removing the soil at the front of the ridge shaping board.
The problem that the space for taking in soil is small and the amount of soil taken in is insufficient
There is .

[0004]

Means for Solving the Problems] However, the present invention is low
Provide a ridge shaping plate behind the claw nails and use a vibrator
Vibrates up and down and connects the intake section in front of the compacting section.
In a ridge coating device that is continuously provided to form a ridge shaping plate,
The inclination angle of the intake section that tilts from high to low
Make the compaction part to be inclined larger than the angle of inclination.
The front and rear widths of the intake part and the compaction part are almost equal
Lower than the soil compaction space below the intake section.
Structured so that the soil intake space is formed large
And take in a large amount of soil from the large space at the front
Forward capture that greatly changes the downward pressing force at an angle
Lightly tapping and pressing the soil, and a small inclination angle
The rear compaction part where the downward pressing force gradually increases with
The work of compacting the soil by smashing the soil before and after the ridge shaping board
Since the pressing force is changed steplessly between the widths,
Mud or smooth moving from the only part to the compaction part, ridge shaping board
It is possible to eliminate the problem that mud is extruded at the front intake,
Prevents muddy shortage in the compaction part and tightens well and collapses
It can easily form difficult furrows .
