Abstract (en)
[origin: EP1369535A1] Shovel dredger comprises a shovel having a slotted hole screen base with several sieve bars arranged a distance apart and pivotably mounted at their front ends about a common axis. Adjacent sieve bars oscillate in different directions. The sieve bars oscillating in the same direction belong to a first (1a) or a second group. The sieve bars are hinged in a comb-like manner on fingers (13) forming a holder fixed on a shaft. Each sieve bar has a bearing bushing (1a') positioned on a shaft journal (21) by a needle bearing (25). The shaft journal and the bearing bushing each have a constant diameter. The bearing journal is provided with a central lubricant channel (21.2) leading from the outer periphery of the shaft journal and opening into a radial lubricant bore (21.3). O-ring seals (26) secured against axial displacement are attached by outer-lying adjusting rings (28) to both sides of the needle bearing.
