Can be easily installed and operated even in a narrow railway track portion without taking up installation space, and the flexibility of the operation can be increased.

In addition, the ballast W continuously scraped from the excavation unit 1 is temporarily removed from the scraper rotor 18 of the scraper 11.
, And the ballast W continuously raked up by the rake 11 is conveyed by the conveyor section 21, so that the rotation of the rake rotor 18 removes large and small crushed stones, gravel, and the like. Even the ballast W can be satisfactorily scraped up and collected, so that the remaining collection can be prevented, the collection efficiency can be increased, and the work efficiency can be further improved.

In particular, a truck 24 connected and towed to the excavation unit 1 is disposed, the conveyor unit 21 is mounted on the truck 24, a crawler crawler track 26 is disposed on the truck 24, and wheels are provided on both left and right sides in the traveling direction. Since the 27 and 27 are provided, the weight of the ballast W conveyed by the conveyor unit 21 can be reliably received by the crawler crawler track 26 and travel.
As a result, the towing traveling of the conveyor portion 21 can be stabilized, and the work can be smoothly progressed. Even if an uneven load is applied to the conveyor portion 21, the wheels 27, 27 on both the left and right sides in the traveling direction can be used.
Can reliably prevent the cart 24 from overturning, and the work efficiency can be further improved accordingly.

In this case, the conveyor unit 21 receives the ballast W picked up by the pick-up rotor 18 and conveys the ballast W. The conveyor unit 21 receives the ballast from the conveyor 22 and conveys the ballast. Since it is composed of the conveyor 29, it is possible to increase the flexibility of the transfer position of the ballast W that is being picked up, and also it is possible to revolve and retract the recovery conveyor 29 during non-operation or the like, thereby increasing the use comfort. In this case, the conveyor 22 is configured so that the turning position can be adjusted. Therefore, by adjusting the turning position of the transport conveyor 22 in conjunction with the turning adjustment of the collection conveyor 29, the further ballast W can be adjusted. The flexibility of the transfer position can be increased.

It should be noted that the present invention is not limited to the structure shown in the above embodiment, and for example, the structure of the scraping rotor 18 is designed by appropriately changing.

[0019]

As described above, since the present invention can be recovered without using human power, it does not force the operator to suffer, and it is possible to remarkably improve the work efficiency. Due to the structure where the upper part and the conveyor part are merged, it is possible to install and work easily even on narrow railway tracks without taking up installation space, to increase the flexibility of work, and to continue from the excavation part The ballast that has been raked out is temporarily lifted up by the rotation of the rake-up rotor above the rake, and the ballast continuously raked up by the rake is transported by the conveyor section. By rotating the upper rotor, even ballasts of various sizes, such as crushed stones and gravel, can be scraped up and collected well, and the collection efficiency can be prevented by preventing the uncollected residue. In particular, a truck connected to the digging part and towed is arranged, the conveyor is mounted on the truck, crawler tracks are arranged on the truck, and wheels are arranged on both left and right sides in the traveling direction. Therefore, the weight of the ballast conveyed by the conveyor section can be reliably received by the crawler crawler track, and the traveling of the conveyor section can be stabilized, and the work can be smoothly performed. Even if an unbalanced load is applied to the conveyor portion, the wheels on the left and right sides in the traveling direction surely prevent the bogie from rolling over, and the work efficiency can be further improved accordingly.

In this case, the conveyor section is constituted by a conveyor for receiving and conveying ballast picked up by the pick-up rotor and a recovery conveyor for adjusting the turning position for receiving and conveying ballast from the conveyor. This makes it possible to increase the flexibility of the transfer position of the ballast that is being scraped up, and at the same time, allows the collection conveyor to revolve and retreat during non-operations, thereby improving the use comfort. Is configured so that the swivel position can be adjusted, and the swivel position of the transport conveyor is adjusted in conjunction with the swivel adjustment of the recovery conveyor, so that the flexibility of the ballast transfer position can be further increased.

As described above, the intended purpose can be sufficiently achieved.
