Self-cleaning auger silt sucking device suitable for underwater desilting robot

The invention discloses a self-cleaning auger silt sucking device suitable for an underwater desilting robot. According to the technical scheme, the auger structure of the existing underwater desilting robot is improved, that is, the structure of a hollow shaft on the auger structure is improved, the design of the hollow shaft allows the water flow to penetrate through the hollow shaft, and the hollow shaft is connected with an external high pressure water pump to enable a spraying nozzle on the hollow shaft to spray high pressure water flow, so that the hollow shaft as well as a first screw blade and a second screw blade on the hollow shaft are cleaned. 本申请公开有一种适用于水下清淤机器人的自清洗绞龙吸淤装置。本技术方案通过对现有的水下清淤机器人的绞龙结构进行改进，即：通过对绞龙结构上的空心轴的结构进行改进，空心轴的设计使得其内能够容纳水流通过，通过与外部高压水泵相连，使得空心轴上的喷淋嘴能够喷射高压水流，从而实现对空心轴及其上的第一螺旋叶片和第二螺旋叶片的清洗。
