[0035] Further, the cross section of the first spiral rod 17 and the second spiral rod 19 is semicircular, so that the first spiral rod 17 and the second spiral rod 19 do not excessively block the seeds, and the comfortable conveying effect of the seeds is ensured.

[0036] Further, the third spiral rod 20 is fixed in the screening body 5, the third spiral rod 20 is intermittently arranged in the screening body 5, and the cross section of the third spiral rod 20 is also semicircular, the rotating direction of the screening body 5 is opposite to the rotating directions of the outer filtering body 16 and the inner filtering body 18, and the fine sand can be moved in the opposite direction of the seeds through the third spiral rod 20 in the screening body 5, so that the fine sand and the seeds can be fully contacted, and the comprehensiveness of the seed surface wear treatment is improved.

[0037] Further, the screening body 5 is provided with a through opening, and the cover plate 8 is installed at the position corresponding to the through opening, and the cover plate 8 is connected with the screening body 5 through bolts, so that the fine sand can be conveniently discharged.

[0038] Working principle: when the gentiana straminea seed screening device is used, first, the cover plate 8 on the screening body 5 is opened, and an appropriate amount of fine sand is added into the screening body 5, then the cover plate 8 is fixed through bolts, and the opening on the screening body 5 is closed, so that the fine sand is prevented from spilling out.

[0039] Then the need to screen the seed of Gentiana crassicaulis is poured into the hopper 10, under the guidance of the guide plate 11 in the hopper 10, Gentiana crassicaulis seed will smoothly into the end of the inner filter body 18, at the same time, start the first motor 4 and the second motor 14, the first motor 4 through the first gear 3 drive gear rail 7 rotation, make the screening body 5 through the drag wheel rail 6 and gear rail 7 on the first gear 3 and the drag wheel 2 on the rack 1 rotation;

[0040] At the same time, the third gear 15 is driven by the second motor 14 to rotate, and the second gear 13 is driven by the third gear 15 to rotate. Since the end of the outer filter body 16 and the inner filter body 18 is integrally arranged and fixedly connected with the second gear 13, the rotation of the second gear 13 can drive the outer filter body 16 and the inner filter body 18 to rotate in the screening body 5;

[0041] When the seed of Gentiana crassicaulis enters the end of the inner filter body 18, the inner filter body 18 is in a rotating state, and the seed of Gentiana crassicaulis is transported forward under the action of the second spiral rod 19. The inner filter body 18 completes the preliminary screening of the seed of Gentiana crassicaulis first, and the large-size impurities are screened out and left in the inner filter body 18, while the seed of Gentiana crassicaulis enters the outer filter body 16. With the rotation of the inner filter body 18, the large-size impurities will be discharged through the first discharge port 9 under the action of the second spiral rod 19;

[0042] The seed of Gentiana crassicaulis in the outer filter body 16 is transported forward under the action of the first spiral rod 17, and fine sand exists in the screening body 5. In the rotating state of the screening body 5, the fine sand is in a turbulent state and can enter the outer filter body 16 and the inner filter body 18 and fully contact with the seed. Therefore, in the process of seed screening, the seed will fully contact with the fine sand, and under the action of the fine sand, the outer surface of the seed can be abraded to facilitate the rapid germination of the subsequent seed;

[0043] In the above process, the rotation direction of the screening body 5 is opposite to the rotation direction of the outer filter body 16. Because the outer filter body 16 and the inner filter body 18 rotate, the fine sand moves and accumulates at the discharge port position. The reverse rotation of the screening body 5 can move the fine sand in the opposite direction of the seed under the action of the third spiral rod 20. In this way, the fine sand can fully contact with the seed, and the abrading quality of the outer surface of the seed can be guaranteed;

[0044] Under the continuous rotating state of the outer filter body 16, the first spiral rod 17 continuously moves the seed forward. When the seed moves to the conical cylinder position at the front end of the outer filter body 16, the seed can be separated from the fine sand, and the smaller-size impurities will also be screened out and stay in the fine sand. The screened seed can be discharged through the second discharge port 12;

[0045] After the device works for a long time, the cover plate 8 on the screening body 5 can be opened, and clean fine sand is replaced, so that the screening work of the seeds is not affected;

[0046] The above is the use process of the screening device, and the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0047] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
