[0027] In summary, the small material mixer for feed production with dust removal function starts the air extraction pump 191 to extract the air in the filter box 10, so that the air containing dust in the mixing box 1 enters the interior of the filter box 10 through the air inlet pipe 12, and then filters the air containing dust through the filter screen 17, so as to perform dust reduction treatment in the mixing box 1, and avoid the pollution of the environment caused by the dust spreading to the outside of the mixing box 1, and the filtered dust will accumulate on the top of the filter screen 17. When the filter screen 17 needs to be cleaned, the two hand wheels 258 can be turned to drive the two worms 257 to rotate, and then the two worm wheels 256 can be used to drive the two threaded rods 252 to rotate, and the two threaded rods 252 will drive the two threaded rods 252 to rotate during the rotation. The slider 254 and the two positioning blocks 255 move away from each other to make the two positioning blocks 255 move out from the inside of the two positioning grooves 24 respectively, thereby releasing the fixation of the two connecting blocks 23. At this time, the cover plate 11 can be lifted up to be removed, and then the mounting frame 16 can be pulled out from the inside of the filter box 10 by the two handles 18 to remove the filter screen 17, thereby facilitating the cleaning of the filter screen 17 and further facilitating the use of the user, and solving the problem that a large amount of dust is often generated when the small materials are stirred during the actual use of the existing small material mixer for feed production, and the existing mixer is unable to carry out dust reduction treatment on the generated dust, allowing the dust to fly out, thereby causing pollution to the production environment.
