绞吸挖泥船及用于绞吸挖泥船的可碎石绞刀装置
摘要：
本申请公开了一种用于绞吸挖泥船的可碎石绞刀装置，其包括吸泥口和设于所述吸泥口外侧的绞刀，所述绞刀包括绞刀轴、绞刀臂和绞刀圈；所述吸泥口中固定设置有用于阻挡大颗粒石块进入所述吸泥口的固定刀片，所述绞刀圈上固定设置有与所述固定刀片相配合、以将阻挡在所述吸泥口外的大颗粒石块破碎的旋转刀片。本申请这种可碎石绞刀装置可自由拆卸，调换方便，在不影响原绞刀的结构上能够有效的防止了石块堵塞现象，对泥泵的吸入效果造成的影响低，避免了停工掏石块工作，保证了绞吸挖泥船的施工效率。
摘要（英）：

This invention discloses a device capable of breaking stones and used for a cutter suction dredger. The cutter device comprises a mud suction port and a cutter arranged on the outer side of the mud suction port; the cutter comprises a cutter shaft, a cutter arm and a cutter ring; the mud suction port is fixedly provided with a fixed blade used for blocking large granular stones from entering the mud suction port; and the cutter ring is fixedly provided with a rotating blade which is in fit with the fixed blade to break the large granular stones blocked outside of the mud suction port. The cutter device capable of breaking the stones can be disassembled freely, replacement is convenient, the phenomenon of stone blocking can be effectively prevented without affecting the structure of an original cutter, the impact on the suction effect of a mud pump is small, the fact that working is stopped for digging the stones is avoided, and the construction efficiency of the cutter suction dredger is guaranteed.
