[0002] During the maintenance of railways, the gravel under the old railway roadbed needs to be replaced regularly. Before replacing and laying new gravel, a railway ballast cleaning device is needed to clean the gravel on the railway roadbed.

[0003] In the prior art, after searching, the utility model patent with Chinese patent publication number CN216765445U discloses a railway slag cleaning machine, such as Figure 1 As shown, it mainly includes a slag chain part a, a slag cleaning plate part b, a mounting part d and a connecting part c. The mounting part d is arranged on the upper part of the slag chain part a and is used to connect with the excavator. The slag cleaning plate part b is arranged at the tail end of the slag chain part a. The slag cleaning plate part b and the mounting part d are connected through the connecting part c. The slag chain part a includes a chain, an upper plate, a lower plate, a skeleton and other structures. The pick includes a plurality of single picks and double picks, and the plurality of single picks and double picks are arranged at intervals. The ballast lifter includes a ballast retaining shell b2, a rotary motor, a rotary shaft b3 and a ballast retaining claw b1 on the rotary shaft. The rotary motor is connected to the rotary shaft and drives the rotary shaft to rotate. When working, the slag chain extends into the lower part of the rails and sleepers in the railway roadbed, and removes stones to one side. The stones move toward the slag cleaning plate part driven by the chain and are thrown to the outside by the ballast retaining claw on the slag cleaning plate part.

[0004] In the actual implementation process of the railway ballast cleaning device similar to the above-mentioned technical solution in the prior art, it was found that there are areas that need to be improved: the slag cleaning plate part (ballast lifter) is set as a structure of a rotating shaft and a ballast blocking claw on the rotating shaft. The ballast blocking claw is circular with the rotating shaft. During the rotation process, the stones are thrown to the outside. The radius of the stone throwing movement is small, which easily causes stone blockage at the ballast lifter. Utility Model Content
