[0027] The cross section of the stirring blade 43 is a trapezoidal structure, the outer side of the stirring blade 43 is inclined, a through groove is opened on the surface of the stirring blade 43, and a guide plate end is arranged on the side of the through groove.
[0028] The bottom end of the folding sleeve 32 is connected to a frame plate 33 , and the four corners of the bottom end of the frame plate 33 are connected to magnets 34 , and the magnets 34 are magnetically docked with the magnetic interface 22 .
[0029] A partition plate 35 is inserted inside the ash outlet of the feed hopper 31 , a groove is formed on the inner wall of the partition plate 35 , and a plurality of filter holes are formed inside the groove.
[0030] The design of the magnetic interface 22 can facilitate the loading of beans and grains, and then secondary screening can be performed without stopping the machine, thereby improving the screening effect of the beans and grains. The pull-out design of the plug plate 24 can facilitate the concentrated removal of the beans and grains inside the screening cylinder 21, and the stirring blade 43 is closely attached to the inner wall of the screening cylinder 21. When the rotating shaft 42 drives the stirring blade 43 to rotate, the stirring blade 43 pushes and cleans the impurities blocked in the leakage holes of the screening cylinder 21 during rotation, thereby reducing the probability of blockage of the leakage holes of the screening cylinder 21.
