Embodiment 1

[0028] Reference attached Figure 1 to Figure 5 .

[0029] A reamer with hydraulic characteristics for a dredger, comprising a knife arm, a hub and a big ring. The knife arm 3 has a recess 10 on the inside, the big ring 6 has an inner ring cavity, and the inner recess 10 of the knife arm extends to the ring cavity of the big ring 6 , Plays the role of diversion of mud flowing in the direction of the large ring 6. The inner edge 4 of the knife arm 3 has an arc groove 9. The inner ring cavity structure of the big ring 6 is a wide upper part 7 of the big ring, the lower part 8 of the big ring is narrowed into a bell-shaped cavity structure, and the wide ring cavity of the upper part 7 is received at the end of the knife arm groove 9. Tooth seats are arranged on the outer edge of the knife arm 3, and each tooth seat is equipped with a detachable knife tooth.

Abstract

The invention relates to a reamer with hydraulic characteristic for a dredger, and belongs to the technical field of environment-friendly dredging. The reamer with hydraulic characteristic for the dredger comprises a tool arm, a hub and a big ring. The reamer is characterized in that: a depression (10) is formed at the inner side of the tool arm (3), an inner ring cavity is formed in the big ring(6), and the depression (10) at the inner side of the tool arm (3) is extended and communicated with the ring cavity of the big ring (6) to play a role in guiding mud to flow in the direction of the big ring (6). The reamer has the advantages of simple structure, convenience for implementing, good soil adaptability, no sand leakage, high construction efficiency and the like.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection dredging, and particularly relates to a reamer with hydraulic characteristics for a dredger. Background technique [0002] At present, in the dredging industry, the reamer is mainly used for the excavation of underwater soil, and the most commonly used is the closed reamer equipped with movable teeth. As the tonnage of ocean-going ships is getting bigger and bigger, the draught is getting deeper and deeper, so the depth that the dredger needs to excavate is getting deeper and deeper, and the excavated soil is getting harder and harder. In order to meet the needs of hard soil, the form of the reamer has been changed from high to short. The top was wide and now it is now narrow and the arms have become much thicker and heavier. At the same time, the curve of the reamer arm is gradually improved, which is conducive to the mud entering the inside of the reamer. [0003] The hub of the ream...
