Description

[Detailed Description of the Invention] Conventional Technology The present invention relates to a leveling machine, in which a mud is dug up to build up on an old ridge, and the leveling machine for compacting the built up soil is vibrated using a vibrating device. It relates to an improved ridge board.

2. Description of the Related Art Conventionally, paddy fields are used to make ridges, to store water by damming them, to serve as a boundary with other people's rice fields, or as a sidewalk for agricultural work.

Conventionally, as a machine for making ridges, various things such as hitting ridges using a lever-crank mechanism, hitting ridges using hydraulic pressure, etc. are known, but these are strokes of the ridge hitting plate when hitting ridges, for example, 100 mm. It was also large, and the repetition frequency was also relatively small. This type of ridge trimming machine is suitable for making sturdy ridges, but for example, partition ridges and sidewalks are provided to prevent seedlings from falling due to ripples in rice fields that have grown due to recent ground improvement. For ridges that do not need to be combined, the ridge striking machine with a shorter stroke and a higher frequency may have better workability.

For this reason, a type of leveling machine that uses a vibrating device to vibrate the leveling plate has also been developed.

Problems to be solved by the invention However, since the ridge plate of this vibration type ridge trimmer has the ridge surface portion of the soil piled up by the rotor as it is, the effect of vibration is obtained when the soil is a large lump. There is a problem that soil compaction due to becomes insufficient.

In addition, the ridge plate of the vibration type ridge trimmer has its ridge surface portion formed in parallel with the length direction of the ridge, and since the soil piled up by the rotor is prepared as it is, all the piled up soil is It was inefficient because it could not enter under the trim surface, and it could escape above the trim surface. Also,
The strength of compacting the soil on the ridge was the same before and after the ridge surface, and the compaction was sometimes insufficient.

Means for Solving the Problems In order to solve the above problems, the present invention oscillates by a mud raising means for digging up mud in a machine frame and raising it to a ridge, and a vibrating device for adjusting the mud raised by the earth raising means. In a trimming machine equipped with a trimming plate having a freely adjustable trimming surface part, the trimming plate rotatably supports a shaft in the machine frame in the width direction of the ridge and in a substantially horizontal direction, and vibrates on the shaft. A vibrating plate equipped with a device is connected so as to be integrally rotatable in the length direction of the ridge, and the ridged surface portion is attached to the vibrating plate so as to be integrally rotatable in the length direction of the ridge. Further, a rotation angle fixing mechanism for fixing the rotation angle to the machine frame is provided so that the inclination angle with respect to the length direction of the ridge can be adjusted, and a rising wall is provided on the front side of the ridge surface portion, The part that touches the raised soil and the front side of the ridge surface part The present invention provides a leveling machine, characterized in that at least one of them is provided with a crushed earth projecting piece for crushing soil.

Action Since the crushed soil projecting piece is provided on either the ridged surface of the ridged plate or its rising wall, the coarse soil raised by the rotor etc. is also crushed and thinned, and the soil enters the ridged surface and tightens due to vibration. Can be effectively consolidated.

In addition, since the slope angle of the ridge surface part with respect to the length direction of the ridge can be adjusted, it is possible to increase the penetration angle of the soil piled up on the ridge by the rotor or the like into the ridge surface part and Since the soil can be squeezed and sent to the rear while vibrating, the compaction can be made stronger toward the rear.
