Railway ballast bed rock ballast recovery device

Abstract

The invention discloses a railway ballast bed rock ballast recovery device. The device comprises a crawler, a first conveying device, a bucket, a second conveying device, a rotating table, a supporting frame, a discharging opening, an annular bucket and a spiral blade. Firstly, steel rails and sleepers are dismantled by workers; a crawler pushes the bucket to move forwards, rock ballast on the ballast bed is shoveled up, rock ballast is conveyed to the lower end of the second conveying device through the first conveying device, the rock ballast conveyed by the first conveying device is conveyed into a concave groove formed in a carriage of the crawler by the second conveying device, a three-phase alternating-current motor drives the spiral blade to rotationally transport the rock ballast into the annular bucket, so that the rock ballast is transferred, then the rock ballast slides into the rock ballast transport vehicle from a discharge port beside the annular bucket, and the rock ballast transport vehicle transports the recycled rock ballast to a specified position to be stored for secondary utilization.

Description

technical field [0001] The invention relates to the field of track slag recovery, in particular to a railway track bed slag recovery device. Background technique [0002] With the development of high-speed railways, the planning of train routes mostly adopts the scheme of direct instead of curved, which shortens the space-time distance between two points. During this development, some of the original railway lines were used for ordinary trains to continue to use, but some railway lines were abandoned. Abandoned railway track beds occupy a large amount of farmland and cannot be utilized, and a large amount of gravel accumulated on the beds cannot be reused. [0003] With the rapid development of my country's infrastructure, the area of ​​cultivated land is gradually decreasing. If the abandoned railways are dismantled and restored to cultivated land, it will effectively increase the usable land area of ​​our country, and then recycle a large amount of gravel on the bed, whic...

AI Technical Summary

Problems solved by technology

During the demolition process of the railway, the rails and sleepers are relatively easy to remove, but the gravel on the track bed is scattered and not easy to be recycled

[0004] In the prior art, the gravel on the railway track bed is mainly recovered manually. Due to the large amount of gravel on the railway track bed, a large amount of manpower is required, and the gravel compacted by the train is not easy to be dug up, which increases the labor of the staff. strength
