The working principle of the invention is as follows:
during operation, firstly, the bucket wheel connecting arm swings to extend out of the excavating mechanism, the bucket wheel descends and rotates to excavate ballast at the end of the sleeper, and the ballast gradually descends to a corresponding excavating depth; in the descending process of the bucket wheel, the ballast scraping device at the bottom of the sleeper ascends relative to the bucket wheel to avoid the sleeper; when the bucket wheel rotates, the whole machine drives the whole machine to move forward through the walking device, a groove is dug out for a ballast at the end of the sleeper, and the length of the groove can accommodate a ballast raking device at the bottom of the sleeper; extending the bucket wheel outwards, and lowering the sleeper bottom ballast raking device into the corresponding groove; starting a scraper chain to cut the track bed, pushing a ballast scraping device at the bottom of the sleeper to gradually cut into the track bed at the bottom of the sleeper from the sleeper end by a rotating mechanism, scraping out the ballast by the scraper chain while cutting, conveying the ballast to a bucket wheel, digging up the scraped ballast and the ballast of the line side slope by the bucket wheel, and lifting and conveying the ballast to a belt conveying device; when the bucket wheel and the ballast raking device at the bottom of the sleeper work, the walking device drives the whole machine to move forward, so that railway ballasts can be continuously dug out and conveyed to the ballast mixing conveying device, the ballast blocking device is mounted at the head of the ballast mixing conveying device, the railway ballasts can be conveyed into the vibrating screen to be screened, the screened clean railway ballasts fall into the ballast separating bucket from the ballast outlet of the vibrating screen, then the ballast separating bucket is backfilled to a railway bed through swinging, and the dirt soil under the screen is thrown off through the dirt soil conveying device and the rotary conveying device. Under the action of the ballast blocking device, the railway ballast can be directly thrown onto the dirty soil conveying belt and thrown off. The new ballast can be conveyed to the ballast distributing hopper and the swing conveyor belt by the new ballast conveying device to be filled into the ballast bed. The complete machine can realize the ballast supplementing operation on the track bed while performing the ballast cleaning operation, can directly throw away the track bed ballast, and simultaneously fills the new ballast into the track bed to realize the ballast replacing operation on the track bed.
