[0002] With the economic development of our country, the requirements for the management of water environment are getting higher and higher. In particular, in the management of coastal tidal flats, sea reclamation projects and saline-alkali land transformation, excavation and dredging in silt removal, and the removal of aquatic plants in rivers, traditional excavators or engineering work vehicles cannot enter the water surface, and it is necessary to design a new type of amphibious excavator or work vehicle to solve the above problems. The core component of the amphibious work vehicle is the water garbage collection net bag. In the prior art, water garbage collection devices mostly use fixed-length filters or steel forks, which cannot have both filtering and shoveling functions. For small floating objects on the water surface, their collection volume and floating efficiency are low, especially when it comes to the removal of aquatic plants in rivers, they cannot efficiently collect plants such as reeds, water hyacinths, and cattails.
