改善したものに関する。[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 leveled up soil is compacted by a vibrating device. The present invention relates to a rectifying plate having improved motion behavior.
従来の技術 田圃には畦を作り、水を堰して蓄えたり、他人の田圃と

ある。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.
このことから、起振装置を用いて整畦板を振動させる型
の整畦機も開発されている。For this reason, a type of leveling machine that uses a vibrating device to vibrate the leveling plate has also been developed.
