Problems solved by technology
However, these excavation chains are relatively simple in operation occasions. Due to the large overall structure, only main line excavation can be carried out, and excavation operations cannot be carried out in occasions such as turnouts, station lines, bridges, tunnels, etc., and the installation method at the chain link is relatively simple. , there is a risk of the chain pin falling off when the whole chain is running, which may easily cause the whole chain to break

The present invention discloses a digger chain applicable to a roadway ballast cleaning machine. The digger chain applicable to the roadway ballast cleaning machine comprises a plurality of first ballast digging rake plates, toothless rake plates, second ballast digging rake plates and intermediate bodies. Ballast digging rake teeth are installed on the first ballast digging rake plates and the second ballast digging rake plates, the first ballast digging rake plates are hinged to the second ballast digging rake plates through the corresponding intermediate bodies and chain pins, the toothless rake plates are hinged to the second ballast digging rake plates through the corresponding intermediate bodies and the corresponding chain pins, and the first ballast digging rake plates, the toothless rake plates and the second ballast digging rake plates are arrayed in sequence to form an annular chain. The digger chain applicable to the roadway ballast cleaning machine is compact in structure, high in wear resistance and safe and reliable.
Description
technical field [0001] The invention relates to a railway ballast cleaning and screening vehicle, in particular to an excavating chain. Background technique [0002] The cleaning truck is a large-scale road maintenance machine used to clean the ballast of the ballast on the railway. Its function is to dig out the dirty and hardened ballast from the bottom of the sleeper, then screen it, and backfill the clean ballast that meets the standard to the ballast. And remove the sieved dirt, crushed ballast, etc. to the outside of the line. The excavation chain is one of the main working devices on the cleaning vehicle, which is responsible for excavating the ballast of the ballast bed. [0003] Documents with Chinese patent numbers 201020642115.8 and 201510953427.8 each mention a kind of excavation chain, which is also assembled in a ring by connecting a number of ballast rake plates and intermediate chain links. The ballast rake plates are also equipped with ballast rake teeth. ...
