Claims (1)

[Scope of utility model registration request] In a ridge shaping machine, the machine frame has an earth raising means for digging up mud and heaping it up into a ridge, and a ridge leveling plate for adjusting the mud piled up by the earth raising means, and the shape of the ridge leveling plate relative to the ridge is adjusted to the top and side surfaces of the ridge. The ridge plate is formed into a nearly curved cross-section with the front side gradually raised, and a vibration generator is installed to allow this ridge plate to vibrate freely, and is supported and fixed to the ridge plate and the machine frame. A telescoping device that expands and contracts at a set position is provided between the base body and a spring that operates as the telescoping device expands and contracts;
A ridge adjustment machine characterized in that the expansion and contraction device and the spring are operated by the vibration of the ridge adjustment plate, and the vibrating device is caused to vibrate the ridge adjustment plate under these operations.
