The invention discloses a light debris collecting device for garbage treatment. The device comprises a vibrating screen, wherein a dust suction hood is mounted on the vibrating screen; a charging portis formed in one side of the vibrating screen from the part between the dust suction hood and the screen box wall to the upper surface of the middle of a sieve plate; a light sieved garbage recoveryreceiving plate is arranged below the sieve plate; coarse waste discharging ports are formed in two ends of the sieve plate respectively; a horn-shaped coarse waste receiving cylinder is arranged on one side below the two coarse waste discharging ports; an induced draft fan is mounted on one side of the vibrating screen; at least two dust collecting boxes are mounted between the induced draft fanand the dust suction hood in series connection through sucking pipes; sieve pores in the sieve plate are distributed like a Chinese character huo (fire). According to the device, mechanical sieving equipment and the dust suction hood are utilized for collecting light garbage debris, so that working efficiency is improved, dust is prevented from polluting surrounding air, and furthermore, labor intensity of a worker is greatly reduced.
