    • In a water jet type underwater ground excavator wherein an underwater pump portion is carried on an excavator body including stabilizer sleds, an excavation portion protrudes downwardly and rearwardly under the excavator body, and water is delivered from the underwater pump portion to the excavation portion and then ejected from jet nozzles of the excavation portion so as to excavate the ground under water, an improvement by a sinker arm erected at a free end of the excavation portion in a manner to ascend and descend with upward and downward motions of the free end, whereby the stability of the excavator is enhanced. By joining to the sinker arm a brake equipment which suppresses the ascent thereof, the stability of the excavator is enhanced.
    • 在水下型水下地面挖掘机中,水下泵部分承载在包括稳定滑车的挖掘机主体上,挖掘部分在挖掘机主体下方向下并向后突出,水从水下泵部分输送到挖掘部分,然后 从挖掘部分的喷嘴喷出,以便在水下挖掘地面,通过以自由端的向上和向下运动的方式上升和下降的方式竖立在挖掘部分的自由端的沉降臂的改进,由此 挖掘机的稳定性得到提高。 通过将沉降片连接到抑制其上升的制动装置,提高了挖掘机的稳定性。
