Abstract

A reamer comprises a hub, a bottom ring and a reamer arm structure. The hub is connected with the upper end of the reamer arm structure, and the bottom ring is connected with the lower end of the reamer arm structure. The reamer arm structure comprises reamer arms, a reamer body, reamer teeth and a pin. Compared with the prior art, due to the facts that the number of the reamer arms is increased and the reamer teeth are arranged in a spiral mode, the single cutting output of the reamer teeth is reduced, so that the impact load is reduced, the excavating stability of the reamer is improved, the average effective power is increased, the ground breaking capacity is improved, and the existing capacity of a ship is released.

Description

technical field [0001] The invention relates to the field of reamers, in particular to a reamer. Background technique [0002] The existing reamer equipment is affected by the angle of the reamer teeth when digging compacted sand, and the efficiency of breaking soil is low. [0003] The existing reamer is a 6-arm reamer, and the reamer teeth are staggeredly distributed. When the sand is compacted, the reamer teeth cut a large amount of soil at a time, resulting in a large impact of the reamer. In order to protect the safety of production equipment and avoid overloading of the hydraulic system or electric drive system due to impact, low speed and small cutting volume are adopted. The average effective power of the reamer during construction is only 1 / 3 to 1 / 2 of the installed power. Each knife arm has only the first three effective cutting teeth, resulting in a large waste of power of the reamer and low efficiency of breaking ground. [0004] Therefore, a series of improvem...
