Reamer mechanism for cutter suction dredger

Abstract

The invention discloses a reamer mechanism for a cutter suction dredger, and relates to the technical field of excavating equipment. The reamer mechanism comprises a reamer blade and a plurality of reamer teeth, a plurality of inserting columns are arranged on the reamer blade side by side, and the reamer teeth are inserted into the inserting columns in a one-to-one correspondence mode through inserting grooves. The reamer teeth and the reamer blade are further connected through forced replacement mechanisms, each forced replacement mechanism comprises a connecting rod, one end of the connecting rod is fixedly connected to the hole end wall of the blind hole of the reamer teeth, and the other end of the connecting rod is detachably connected to the reamer blade. The fixed connection positions of the hole end walls of the blind holes and the connecting rods are located at the design abrasion limit positions of the reamer teeth. According to the reamer mechanism, the abrasion of the reamer teeth in use is gradually reduced and shortened, so that the connection effect of the forced replacement mechanisms on the reamer teeth is invalid, the reamer teeth are easily separated from the inserting columns, and related maintenance personnel are prompted to add new reamer teeth in time, so that a good digging effect is kept, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of excavating equipment, in particular to a reamer mechanism for cutter suction ships. Background technique [0002] Cutter suction boat is a common water excavation equipment, through the high-speed rotating reamer mechanism to suck excavated crushed sediment into the hull, the reamer mechanism plays an indispensable and important role in the cutter suction boat. [0003] The existing patent announcement number is: CN204940394U, the name of the patent is "a cutter head for cutter suction dredger", the patent includes the bottom ring of the cutter, on which there are many arc-shaped cutter Knife arms, the tops of multiple reamer arms are fixed on the reamer hub, and there are multiple sets of matching reamer teeth on the reamer arms. The curvature of the reamer arms is divided into four types. The reamer arms contain the same The reamer teeth with adaptive curvature have the effects of small leakage, simple...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, multiple reamer teeth are often fixed on the reamer blade of the cutter suction marine reamer mechanism to increase the sharpness during excavation. Due to the nature of the work, long-term use will cause serious wear or loss of the reamer teeth. Hard objects such as hard rocks are deformed when they are hit by hard objects, so the reamer teeth must be replaced regularly. In order to facilitate replacement, most reamer teeth are detachable on the reamer blade. Due to cost or laziness and dereliction of duty, it is often not timely to replace the reamer teeth that are already in poor condition, resulting in excessive wear of the reamer teeth and a decrease in work efficiency, thereby affecting the actual excavation effect, and even causing further damage to the reamer blade.
