Abstract

The invention relates to a screening device for railway ballasts, which comprises a rack, a first vibrating screen, a second vibrating screen, a mixed ballast conveyor A, a mixed ballast conveyor B, a cleaning ballast conveyor, a waste ballast conveyor, a first ballast separating bucket, a second ballast separating bucket and a swinging conveyor, wherein the first vibrating screen and the second vibrating screen are arranged on the rack in the same direction; the mixed ballast conveyor A and the mixed ballast conveyor B are arranged above the first vibrating screen and the second vibrating screen to form a railway ballast feeding system; and the cleaning ballast conveyor and the waste ballast conveyor are arranged below the first vibrating screen and the second vibrating screen. According to the screening device for the railway ballasts, which is disclosed by the invention, the double screens are arranged in the same direction in a limited space so that the railway ballasts are screened efficiently and the separated railway ballasts are respectively conveyed; and through a leveling oil cylinder connected between the rack and a bogie, the vibrating screens can be leveled in a screening process of railway curve ballasts, the requirement of operation on a curve is met, and the application range is wide.

Description

technical field [0001] The invention relates to a railway line maintenance machine, in particular to a device for screening track ballast. Background technique [0002] For the existing ballast cleaning machines, most of them are single vibrating screens with low screening efficiency, and the existing double screens are arranged in reverse, which cannot completely ensure that the ballast feeding direction is consistent with the ballast flow direction on the screen surface. affect the screening efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of low screening efficiency in the prior art and to provide a ballast screening device which utilizes two vibrating screens arranged in the same direction to realize high-efficiency screening of ballast, and can clean the cleaned road after screening Ballast, under-sieve soil and waste ballast are transported separately. [0004] The technical solution of the present in...
