Description

Detailed Description of the Invention

[0001]

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

[0002]

[Prior Art] A rotary is used to lay the earth on the original ridge,
A tractor-implementing type ridge coating with a ridge coating device that vibrates the ridge shaping plate to continuously form ridges on the left and right sides behind the tractor to perform ridge coating work when the tractor is running. There is an opportunity.

[0003]

However, in the case of such a ridge coater, since only one side of the ridge can be ridged, it is possible to perform ridge coating on both sides of the ridge such as the middle ridge in one stroke. There was a problem of not having. In addition, in the case of single-sided coating, there is a problem that lateral vibration is severe and the running property and workability are impaired, and the left-right balance of the machine body becomes unbalanced, resulting in lack of work stability.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention provides
Equipped with the left and right rotary which performs earthing from the left and right sides of the two original ridges, and the left and right ridge shaping plates that shape the upper and left slopes of the ridge after the earthing at the same time. It is intended to improve efficiency by enabling double-sided coating of ridges.

Further, both sides of the vehicle body of the traveling vehicle are supported by the traveling portion so that the supporting height can be freely adjusted, and even if there is a step on the ground surface of the left and right traveling portions with the ridges in between, a proper double-side coating on the left and right sides is performed. Is what makes it possible.

Furthermore, the left and right rotary and ridge shaping plates are mounted on the front or rear side of the traveling vehicle so that the left and right mounting widths and the vertical support heights can be adjusted to enable double-sided coating appropriately corresponding to the ridge width. At the same time, it is possible to apply ridges on one side.

[0026]

As is apparent from the above-described embodiments, the present invention is based on the left and right rotary (13) for embanking one original ridge (A) from the left and right sides, and the upper and left and right slopes of the ridge after the embankment. Since the left and right ridge shaping plates (15) for simultaneously shaping the vehicle are installed on both the left and right sides of the traveling vehicle respectively, 1
It is possible to apply both sides of the ridge in the process, and it is possible to improve the efficiency in the ridge coating work such as forming the middle ridge.

Since both sides of the vehicle body (3) of the traveling vehicle are supported by the traveling portion (2) so that the supporting height can be adjusted,
Even if there is a step on the ground contact surface of the left and right running portions (2) that are in the ridge, it is possible to apply the both sides in an appropriate manner and to hold the vehicle body (3) horizontally.

Further, since the left and right rotary (13) and the ridge shaping plate (15) are mounted on the front or rear side of the traveling vehicle so that the left and right mounting widths and the vertical supporting heights can be adjusted, the ridge width is large and small. Regardless of the above, it is possible to always apply good double-sided coating that appropriately corresponds to the ridge width, and also to enable single-sided coating of the ridges, improving the workability in this ridge coating work. It has a remarkable effect.
