能率向上に極めて有効である。(Effects of the Invention) As described in detail above, in the present invention, the excavation blade is formed into a pocket shape, so that the loose material scraped into the excavation blade is reliably guided to the bucket side without leaking from the excavation blade. Ru. Therefore, as in the past, when loose materials are scraped toward the bucket side,
The driven chain wheel no longer experiences resistance from loose objects, and there is no longer a need for a larger drive source.
Regardless of front or side excavation of the elevator, the clearance angle formed on the excavation blade reduces the resistance caused by contact with bulk materials, which not only improves excavation performance but also reduces wear on the excavation blade. Moreover, since the excavated bulk material is reliably guided to the bucket side, it is extremely effective in improving the efficiency of the unloader.
