Embodiment Construction
[0021] Rock soil excavation device 1 comprises frame 2 and chain 3, and chain 3 is made up of chain piece 4 and pin shaft 5; Chain piece 4 comprises two kinds of structures of common chain piece 4-1 and the chain piece 4-2 that contains digging knife 6, The length of the chain piece 4-1 and the chain piece 4-2 is equal to or slightly less than twice the chain pitch, so that the granularity of rock and soil entering through the chain piece 4-1 and the chain piece 4-2 can be controlled within the design value.
[0022] The chain pieces 4 in the width direction of the chain 3 are densely distributed.
[0023] The chain pieces 4 densely distributed in the width direction are composed of several chain pieces 4-1 and several chain pieces 4-2.
[0024] The chain pieces 4 - 2 are arranged at intervals along the length direction of the chain 3 .
[0025] The chain 3 includes several standard segments, and on the horizontal projection of each standard segment, the knives 6 on the chain...
