Sleeper bottom ballast screen scarifier capable of automatically supplementing ballast and using method

Abstract

The invention discloses a sleeper bottom ballast screen scarifier capable of automatically supplementing ballast, and belongs to the technical field of ballast cleaning machines. The sleeper bottom ballast screen scarifier comprises a front traction head, a lower plate is fixedly connected to the side wall of the front traction head, an upper plate is connected to the top of the lower plate in anattached manner, and a rear connecting plate is connected to the end, away from the front traction head, of the upper plate; consistent through holes are longitudinally formed in the upper plate and the lower plate in a penetrating manner, inserting columns are movably inserted into inner cavities of the through holes, the top ends and the bottom ends of the inserting columns extend out of the inner cavities of the through holes, top plates are arranged at the tops of the inserting columns, screw rods are fixedly connected to the bottoms of the inserting columns, and the peripheries of the screw rods are sleeved with nuts; and moving wheels are evenly arranged at the bottom of the rear connecting plate, a transverse plate is arranged at the top of the rear connecting plate, and a verticalplate is connected to one side of the top of the transverse plate. In the using process of the sleeper bottom ballast screen scarifier, the ballast can be cleaned, and the new ballast obtained after ballast cleaning can be automatically supplemented back to a ballast bed.

Description

technical field [0001] The invention relates to the technical field of ballast cleaning and screening machines, in particular to a bed ballast cleaning and screening machine capable of automatically replenishing ballast and a method of use thereof. Background technique [0002] Ballast cleaning and screening is to excavate and screen the dirty ballast from the bottom of the pillow to a depth of 30-40cm. After screening, the qualified ballast is backfilled on the track, and some new ballast is added to form a clean ballast bed. Screen cleaning is an important means to restore the performance of the ballast bed, especially in the long-term passage of freight trains such as mud pumping and transportation of coal and ore, it must be cleaned regularly. [0003] However, most of the existing ballast cleaning machines cannot automatically replenish new ballast to the ballast bed during the working process, but a large amount of smaller ballast and coal ash will be discharged during...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing ballast cleaning machines cannot automatically replenish new ballast to the ballast bed during the working process, but a large amount of smaller ballast and coal ash will be discharged during the dirty ballast cleaning process. The amount of ballast after cleaning is not up to the standard, and the ballast bed needs to be repaired again. Repeated operations reduce production efficiency. Therefore, a bed ballast cleaning machine that can automatically replenish ballast and its use method is of great practical value.
