The present invention provides a multi-functional screening device for wetland plants having purification function, comprising a bottom plate, moving wheels, a support table, a cylinder, a connecting housing, a rotating electric machine, PLC, key-press, an adjustment fixation connection frame structure, an assembly ring, a mesh, a nonwoven layer, a reinforcement mesh, and a drug storage and delivery box structure, an adjustment storage connection drum structure and a sundries assembly and cleaning frame structure. The moving wheels are bolted to the left and right sides of the lower surface of the bottom plate respectively. The support table is welded to the left and right sides of the upper surface of the bottom plate respectively. The cylinder is bolted to the rear side of the middle part of the lower surface of the support table. The connecting housing is welded to the output shaft of the cylinder. The beneficial effect of the present invention is that providing a sundries assembly and cleaning frame structure can achieve scraping of cleaned sundries on the outer wall of the reinforcement mesh when the reinforcement mesh is raised and avoid effect of residual sundries on water in other environments after the device is transferred and used again.La présente invention concerne un dispositif de tamisage multifonctionnel pour des plantes de milieux humides ayant une fonction de purification, comprenant une plaque de fond, des roues mobiles, une table de support, un cylindre, un boîtier de connexion, une machine électrique rotative, un automate programmable, une touche directe, un bâti de connexion d'ajustement de fixation, une bague d'assemblage, un treillis, une couche non tissée, un treillis de renforcement, une structure de boîte de stockage et de distribution de médicament, une structure de tambour de connexion d'ajustement de stockage de réglage et une structure d'assemblage et de nettoyage d'articles divers.
