Description

TECHNICAL FIELD The present invention relates to a highly versatile ballast straightening machine that can be used as an accessory or attachment for a road-rail vehicle or a road-rail construction machine.

Ballasted tracks are widely used in railroad trackbeds.
A ballasted track is a structure in which ballast such as crushed stone or gravel is laid, sleepers are arranged on top of the ballast, and rails are laid.
In such a ballasted track, trains repeatedly run on the rails, so that the rails gradually become distorted.
For example, a large vehicle called a multiple tie tamper is used to lift rails, replace sleepers, replenish ballast, and harden the ground.
In such track maintenance work, some ballast is scattered on the rail joints and sleepers, so it is necessary to remove the scattered ballast as a post-treatment, but so far this has been done manually. Therefore, the work was difficult.

Patent Document 1 discloses a ballast in which a first brush and a second brush are attached so as to spread downward from a rotating shaft, and the second brush is attached to the first brush so that the second brush spreads more than the first brush. An organizing device is disclosed.
However, in such a structure in which the brushes are arranged so as to spread downward from the rotating shaft, there is a technical problem that the tip of the brush is difficult to enter into the fastening portion of the rail.
