As shown in FIG. 1, when the screening device for food purchase of the present invention is used, first, the grip bar 80 is held, so that the third filter net 81 rotates around the sixth bracket 83 and then falls into the third frame 71. The food to be screened is then returned to the original position by holding the grip bar 80, and then the cylinder 61 and the first fan 691 are activated, and the first fan 691 is electrically connected to the power source. The cylinder 61 drives the push rod 64 to move up and down, thereby driving the shunting block 66 and the third filter ring to move up and down, so that the grain on the third filter ring moves up and down, thereby separating the grain from the dust therein. Then, the second fan 89 is activated. The first fan 691 filters the outside air through the first filter ring 54 and enters the first pipe 69. After filtering through the third through hole 671 and the second filter 68, the third fan is filtered. The gas is ejected from the frame 71. At this time, since the grain is separated from the dust and impurities therein, the separated dust can be blown upward during the movement of the grain up and down, and the second fan 89 is activated to cause the inside of the cover frame 86. The dust can enter the second duct 88 and then be discharged.

The screening effect is better. Then, the first motor 41 is activated, so that the first rotating shaft 42 drives the first frame 43 to rotate, so that the grain is centrifugally moved in the first frame 43 so that the food required in the first frame 43 is concentrated to the first frame. Inner surface of body 43 Up and at the upper surface of the first frame body 43, and then rotating the second roller 36, the first fixing block 33 is moved downward by the cooperation of the first saw tooth 37 and the second saw tooth 331, and the first vertical rod The lower end of the 34 abuts against the cushion pad 15, and the cushion pad 15 is elastically deformed to support the first upright rod 34. The first vertical rod and then the lifting plate 31 are moved downward, so that the first motor 41 moves downward, thereby causing the first frame 43 to move downward, and the upper surface of the first frame 43 and the second frame 51 are at this time. The lower surface is no longer in contact, and then the required food is swept around the upper surface of the first frame 43 and passes through the concentrated action of the third frame 76 to enter the lower portion, and enters the receiving box 23 through the fourth through hole 761. Then, the first baffle 24 is taken out by holding the grip frame 25, so that the grain in the receiving box 23 is discharged through the second through hole 231 after being concentrated by the collecting ring 26, thereby facilitating collection of the screened grain. . So far, the use process of the screening device for food purchase of the present invention has been described.
