Detailed Description

As shown in the attached drawings 1 and 2, the utility model discloses a proportion mesa 301, be located the dust excluding hood 302 of proportion mesa 301 top, be located the below of proportion mesa 301 and be used for driving the drive arrangement 308 of the vibration of proportion mesa 301 and set up respectively at the play hopper 306 and the lower discharge hopper 307 of two discharge gates under the proportion mesa 301, fixed connection forms sealedly between the corresponding side of the last discharge end of play discharge gate 306 and proportion mesa 301 and dust excluding hood 302, fixed connection forms sealedly between the lower discharge end of play discharge gate 307 and proportion mesa 301 and the corresponding side of dust excluding hood 302. Simultaneously, two side edges of the dust hood 302 are fixedly connected with two side edges of the specific gravity table board 301, so that the dust hood 302 is sealed with four side surfaces corresponding to the specific gravity table board 301, and only the upper discharge hopper 306 and the lower discharge hopper 307 are provided with discharge ports with smaller calibers, so that the sealing degree between the dust hood and the specific gravity table board 301 is greatly improved, the air volume utilization rate is improved, and the dust removal effect is better under the condition of the same air volume. The fish scale sieve is detachably mounted on the specific gravity table-board 301 and the mounting plate 312 of the upper and lower discharge hoppers, so that the fish scale sieve sheets can be conveniently replaced.

As shown in fig. 3, a rotating shaft 314 is arranged in the upper discharging hopper 306, a baffle 313 is fixedly mounted on the rotating shaft 314, the position of the baffle 313 corresponds to the position of the fish scale screen upper discharging port of the specific gravity table 301, a mounting plate 312 for mounting the fish scale screen is further arranged in the upper discharging hopper 306, and the baffle 313 is positioned above the mounting plate 312.
