When the bucket wheel excavates the sediment in the underwater soil layer, the bucket wheel rotates. When the bottom mud bucket is turned to the lower part, the soil layer sediment is excavated and loaded into the mud bucket. When the bottomless bucket continues to rotate the top part, the dredged sediment contained in the bucket passes through the opening at the bottom end of the bucket (bottomless), and is forced to discharge into the fixed bucket between two rotating rings by the action of a fixed scraper. In this way, it can make each rotating bottomless hopper excavated and carried sediment, almost all can be poured into its fixed hopper, the mixture of sediment and water through the hopper into the suction suction pipe, and finally is sucked by the mud pump. Authoritative statistics based on practical effects , when digging hard soil, the bucket wheel has a 2:1 to 3:1 productivity ratio compared to the basic reamers, and the mud concentration can reach 30 to 33%, while the general reamers are only about 15%.
Bucket wheel and general reamer compared with the following advantages:
(1) the bucket wheel has no bucket bottom, mining performance is good, the cutting force of the bucket wheel is larger than the reaper, suitable for digging hard soil and dense sand, and for all kinds of soil, can obtain continuous high concentration of production.
(2) the bucket wheel dredging flatness is better, the bucket wheel leakage is less.
(3) a scraper is installed on the bucket wheel, which can include the residual soil stuck on the bucket body into the suction chamber.
(4) The dredging is not affected by the change of swing direction, and can be continuously and effectively excavated, and the direction of mud cutting is always bottom-up.
(5) in the dredging operation smooth operation, vibration and noise are very small.
(6) the total installed power can be reduced compared with the general cutter suction dredger.

Bucket wheel dredger not only has the advantages of dredging, transporting and discharging of suction dredger, continuous operation, good construction quality, high productivity and low cost, but also further improves the cutting and digging capacity of the dredger, capable of digging hard soil, and digging the working surface is relatively flat, good quality of construction, but the ability of dredging for the thin layer is poor. Bucket wheel dredger is greatly affected by the row distance, more than the rated row distance of the equipment must increase the relay pump, the cost increases significantly; Floating pipe has a certain impact on the navigation, the use of submerged pipe technology can reduce the impact.
Bucket wheel dredger suitable for dredging soil categories for Ⅱ ~ V, suitable for excavation of a wide range of soil, such as various types of silt, clay, sand and gravel, etc., more used in large rivers and rivers dredging projects and low-lying ponds land blowing project.
