BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ballast ballast removing machine for excavating and transporting ballast on a railway track to remove it.

[0002]

2. Description of the Related Art As a machine for excavating / transporting and removing ballast on the bed of a railway track, there is known a machine disclosed in JP-A-7-34402. In this machine, an endless chain body is attached to the front part of a vehicle body equipped with a traveling body, a belt conveyor is continuously installed from the discharge part of this endless chain body to the rear part of the vehicle body, and the endless chain body excavates ballast on the roadbed. -It is a machine that conveys and discharges it onto a belt conveyor, and the belt conveyor conveys ballast to the rear part of the vehicle body.

[0003]

In the above-mentioned machine, since the ballast of the roadbed is excavated by the endless chain body and conveyed to the belt conveyor attached to the vehicle body, the endless chain body has a substantially horizontal horizontal portion and a vertical portion. And a shape having a curved portion in which the horizontal portion and the vertical portion are continuous.

Since the above-mentioned endless chain body has a curved portion, the ballast conveyed to the curved portion is likely to be clogged, so that the feeding speed of the endless chain body is slowed and the curvature of the curved portion is increased to the curved portion. I try not to block the ballast. In addition, in order to increase the excavation ability of the endless chain body, it is necessary to increase the curvature of the curved portion to move smoothly while having high strength. As described above, in the conventional machine using the endless chain body, it is necessary to increase the excavation and transfer capability and to increase the curvature of the curved portion in order to continuously transfer the ballast to the conveyor without clogging. When the curvature of the curved portion is large, the lateral portion becomes short if the total length of the endless chain body is the same, and if the lateral portion is lengthened, the total length of the endless chain body becomes long. If the sideways portion is short, the effective excavation range becomes short, and if the total length of the endless chain body is long, the endless chain body protrudes more to the side than the vehicle body.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a ballast removing machine for a roadbed which can solve the above-mentioned problems.
