The invention relates to the technical field of track maintenance equipment, and discloses an excavation chain structure of a ballast cleaning machine for railways, which comprises a chain frame, a mounting rake plate is fixedly mounted on the upper surface of the chain frame, and a connecting piece is movably mounted on one side of the chain frame in a sleeving manner. According to the excavationchain structure of the ballast cleaning machine for the railway, the rake teeth and the mounting sleeve are movably sleeved, the rake teeth achieve the reciprocating telescopic excavation process under the combined action of the elastic action of the spring and the shape and size of stones, a wavy excavation face is formed on the surface of ballast, and the sliding rod is pushed to extend out along a vertical hole of the mounting sleeve under the transmission action of the rocker; the raking tooth has the impact loosening effect on the digging surface of the raking tooth, so that the subsequent digging surface of the raking tooth is loosened, large instantaneous impact force is not needed, the service life of the raking tooth is prolonged, and meanwhile, due to the wavy digging surface, the pushing force for pushing ballast and the rolling of the ballast, the subsequent raking tooth still has a relatively strong telescopic function, and the sliding rod can extend out and loosen.
本发明涉及轨道养路设备技术领域，且公开了一种铁路用道碴清筛机的挖掘链结构，包括链架，所述链架的上表面固定安装有安装耙板，所述链架的一侧活动套装有连接件。该铁路用道碴清筛机的挖掘链结构，通过耙齿与安装套活动套装，并受弹簧的弹性作用和石子形状尺寸共同作用，耙齿达到往复伸缩挖掘过程，在道碴表面形成波浪状挖掘面，并在摇杆的传动作用下推动滑杆沿着安装套的垂孔伸出，对耙齿的挖掘面具有撞击疏松的作用，从而使得后续的耙齿挖掘面疏松，不需要很大的瞬时撞击力，延长耙齿的使用寿命，同时由于挖掘面的波浪状，和推动道碴的抵推力以及道碴的翻滚，使得后续的耙齿仍具有较强的伸缩功能，保证滑杆可以伸出疏松。
