Water surface plastic garbage collecting device

According to the water surface plastic garbage collecting device provided by the invention, the vacuum pump and the vacuum generator work cooperatively, the spray pipe of the vacuum pump sprays compressed air, jet flow is formed at the outlet of the spray pipe, entrainment flow is generated, and air around the outlet of the spray pipe is sucked away under the entrainment effect; the pressure in the adsorption cavity of the vacuum generator is reduced to be below the atmospheric pressure, a certain vacuum degree is formed, negative pressure is provided for the suction cup through pipeline connection, plastic garbage is adsorbed accordingly, and then the garbage is placed in the collection box. The plastic garbage adsorption device is suitable for adsorbing various plastic garbage such as plastic bags, plastic bottles and plastic foam, the structure is simple and stable, the immersion depth is reduced, and the situation that the garbage is stranded or wound by underwater plants during operation is avoided. 本发明提
