SUMMARY OF THE INVENTION The prior art described above has a
Is it a structure that mainly removes the upper side of the former ridge by using nails?
On the former ridge where the soil has been lowered due to rainwater
Surface becomes even lower, and a large amount of mud for new ridges is required.
And the amount of mud placed by the rotary claw tends to be insufficient.
There is a problem, and mud flows down from the top surface,
The problem that the shaving amount of the layered ridge slope tends to be insufficient
There is. Therefore, Japanese Patent Application Laid-Open No. 62-190002 discloses
As shown in FIG.
No. 903, the length of the pre-processed nail is about twice or more.
It is necessary to provide a rotary claw.
While it is not easy to simplify the nail mounting structure,
Improvement of pretreatment claw function and lifting of mud by rotary claw
There is a problem that the function cannot be easily improved .

[0004]

Means for Solving the Problems However, the present invention is based on the original row.
Pre-processing claw that performs pre-processing work to remove
Rotary claw to put mud on ridge surface and mud on original ridge surface
In addition to providing a ridge shaping member to form a new ridge by shaping,
Take one end of the preprocessing drive case into the body case via the support shaft.
Attach and pre-process the other end of the drive case via the claw shaft
In the ridge coating device that supports the nails, the pretreatment drive case
Pre-processing drive between the support shaft and claw shaft when in a substantially horizontal posture
Place the rotary pawl shaft at approximately the same height as the case,
The claw shaft is arranged in the rotation trajectory of the rotary claw when viewed from the front.
And a substantially horizontal straight line connecting the support shaft and the claw shaft and the upper surface of the former ridge.
Are arranged so that they are approximately the same height.
Attach the end of the pretreatment nail of the drive case to the shoulder of the former ridge.
Can be translated along the part, mainly the shoulder or slope of the original ridge
Pretreatment nails can be applied to the original ridge to scrape off, such as rainwater
This reduces the amount of soil shaving on the upper side of the base ridge where the soil flows,
And the amount of soil removal on the side of the original ridge slope where the soil on the top side is laminated
Increase the amount of mud necessary for the formation of new ridges on the rotary claw.
Supply and the lack of mud that forms the upper surface of the new ridge
It can be easily prevented and a set of pretreatment nails
Pretreatment can be performed properly, and it is less than twice the length of pretreatment nails.
