Background Irrigation channels (irrigation channels) are important infrastructure for guaranteeing agricultural production and improving rural economy, and have important supporting effects on realizing farmland drought and waterlogging conservation and stable high yield. The bottom sludge of the irrigation canal is accumulated thicker and in a block shape due to the factors of long-term rain wash, natural dust fall and the like, so that the water grass grows, and the irrigation canal water-passing effect is affected. In addition, when the aquatic weeds are broken or rotten, if the aquatic weeds are not salvaged in time, humus in the channels is increased, and nutrient substances are increased, so that the aquatic weeds grow maliciously, and therefore the aquatic weeds in the irrigation channels need to be cleaned in time. At present, the methods for cleaning the aquatic weeds mainly comprise the following steps: 1. The oil saw, the dry fork and other tools are adopted for manual cleaning, the efficiency of the mode is low, and the consumed labor cost is high; 2. A water weed cleaning device is adopted as the prior patent publication No. CN114885668A, and comprises an engine, a propulsion system, a cutting device, a conveying device, a rolling dehydration device, a catalyst adding device, a stirring device, a compression device, a weed storage bin and the like. Cutting the aquatic weeds by a cutting device, converting the aquatic weeds by rolling and adding a catalyst, and finally conveying the aquatic weeds to a grass storage bin. Because the irrigation canal structure is narrow, influenced by environment and time, the bottom silt is thicker and has hard block shape, but the grass roots of the aquatic weeds cannot be fully cut by the cutting device, so that the aquatic weeds are not thoroughly cleaned. Further, sludge and aquatic weed are treated together, and separate collection cannot be realized.
