Fig. 2 discloses a first embodiment of the present invention: the utility model provides a take dust collector 9's rice classifying screen, includes sieve case 1, sets up the material loading mouth 2, the setting at sieve case 1 top are in sieve ship 3 in the sieve case 1, and set up the vibrating device 4 of sieve ship 3 bottom, its key lies in, follows sieve ship 3's direction of height has arranged multistage oblique screen cloth 5 down in parallel, screen cloth 5's sieve mesh top-down reduces step by step, and its end links up one respectively and connects hopper 6 still be provided with first suction hood 7 in the sieve case 1, first suction hood 7 has dust collector 9 through 8 intercommunications of first dust absorption pipeline. The sieve vessel 3 is supported at the bottom wall of the sieve box 1 by means of an elastic support 16. The vibrating device 4 comprises an eccentric 17 rotatably connected to the bottom of the sieve vessel 3, which eccentric 17 is driven in rotation by a drive motor 18.

In specific implementation, a dust removal box 10 is integrated on the outer side wall of the screen box 1, and the dust removal device 9 is arranged in the dust removal box 10. First dust excluding hood fixed mounting be in the inside wall of sieve case 1, and follow the direction of height of sieve case 1 extends. Preferably, the dust removing device 9 is a cyclone dust remover.

In order to absorb the raised dust generated during the rice feeding, a second dust hood 11 is arranged on the feeding port 2, and the second dust hood 11 is communicated with the dust removal device 9 through a second dust collection pipeline. In the case of providing a second dust suction pipeline, the air outlets of the first dust suction pipeline 8 and the second dust suction pipeline may be communicated with the air inlet of the dust removing device 9 at the same time.

In order to facilitate workers to clean rice bran powder and dust adsorbed by the dust removal device 9, a dust collection groove 12 is movably connected to the bottom of the dust removal box 10, and an opening of the dust collection groove 12 corresponds to an ash outlet of the dust removal device 9.
