Abstract:
     It is capable of digging up earth, piling it up on the old ridge and tamping the piled-up earth with pounding plates to make the ridge solid. As a whole, the ridging machine is a forming machine which has an earth-digging and piling-up structure, and shaping plate to shape the piled-up earth. The machine is fitted with a hydraulic pump consisting of a power piston and a hydraulic cylinder, a piston device with a piston and cylinder to make the shaping plate move back and forth freely, and the pipings connecting the hydraulic cylinder and the piston device. The hydraulic pressure produced by advacing and retreating of the piston in the hydraulic pump is transmitted to the piston device by the oil circulation in the pipings.
