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

The utility model discloses a self-cleaning auger silt suction device suitable for an underwater desilting robot. According to the technical scheme, an auger structure of an existing underwater dredging robot is improved; namely, the structure of the hollow shaft on the packing auger structure is improved, water flow can pass through the hollow shaft due to the design of the hollow shaft, the spray nozzle on the hollow shaft can spray high-pressure water flow by being connected with an external high-pressure water pump, and therefore the hollow shaft and the first spiral blade and the second spiral blade on the hollow shaft can be 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。
