Manner of digging out the ballast soil because it is for grooving for ballast removal of roadbed of railroad raceway and the soil and for land ground leveling and one for bench-cut of the slope for housing land development and the like.
Manner of digging out the ballast soil because it is for grooving for ballast removal of roadbed of railroad raceway and the soil and for land ground leveling and one for bench-cut of the slope for housing land development and the like.
PURPOSE: To increase workability by specifying the speed of a chain body when a ballast layer is scraped off by an endless chain band supported pivotally on a V-shaped guide panel body. ;CONSTITUTION: A top end 15 of a guide panel body 12 is made in contact with the side surface of a ballast layer 14, moved in digging direction by a hydraulic cylinder body 9, and ballast is scraped off by an endless chain band supported pivotally inside it. Next the ballast scraped off is discharged from a scraped-off ballast discharge part 17, and transported by belt conveyors 3, 4, and 5. Then the movement speed of the chain band is set to approx. 2m/sec. or over, desirably at approx. 3 to 5m/sec. The chain band is connected to an elliptic chain ring body, and a wide plate body with projected body for soil scraping off is fixed to it. Also, using liftable front wheels 29 and rear wheels 31 on rails 6, and using a caterpillar traveling machine 30 on a general road, traveling is performed. Between these two travel modes, a hydraulic rotating shaft 32 is rotated for transfer. Thus work can be made even in narrow area and work efficiency can be increased.;COPYRIGHT: (C)1995,JPO
