[0015] A ginseng breeding method, comprising the following steps:

[0016] S1, Gastrodia elata distribution: First, the gastrodia elata is sent into the distribution assembly, so that it is continuously distributed in a circular motion. The distributed gastrodia elata then enters the upward airflow released by the built-in cylinder, and starts to receive the screening process of hollowed gastrodia elata;

[0017] S2, Screening gastrodia elata: Continue the step S1, the gastrodia elata is further classified in the upward airflow released by the built-in cylinder. The normal gastrodia elata is not affected by the upward airflow and falls downward due to its own weight. The hollowed gastrodia elata is lighter due to its internal hollow, so it will remain in a hovering state in the upward airflow.

[0018] S3, Hollowing rejection: The upward airflow released by the built-in cylinder is returned by the return assembly and converted into a horizontal circular airflow. The hollowed gastrodia elata hovering in the upward airflow is blown out by the circular airflow. The blown-out gastrodia elata falls into the space between the built-in cylinder and the outer cylinder. The buffer assembly is used to avoid the impact of the blown-out hollowed gastrodia elata on the inner wall of the outer cylinder. Then the hollowed gastrodia elata falls into the semicircular box at the bottom of the outer cylinder for collection.

[0019] S4, Good product collection: The normal gastrodia elata that falls off enters the funnel plate and rolls down. The lower discharge pipe equipped with flexible hair rings is used for cleaning and buffering output, which slows down the falling speed to reduce damage, and finally falls into the receiving box at the bottom of the lower discharge pipe for collection.

[0020] Advantages: Compared with the prior art, the advantages of the present application are: 1. By setting the built-in cylinder, the inner ring opening, the funnel plate, the annular discharge port and the outer cylinder, the annular upward airflow sprayed by the inner ring opening is used to screen the gastrodia elata, so that the hollowed gastrodia elata hovers, and the high-quality gastrodia elata naturally falls into the funnel plate and is discharged, which significantly improves the screening efficiency and the quality of gastrodia elata breeding.

[0021] 2. By setting the upper cover plate, the lower flow guide umbrella, the skeleton, the flow guide column and the ring air jet, the annular airflow sprayed by the inner ring opening passes through the flow guide space composed of the upper cover plate, the lower flow guide umbrella and the skeleton, and is converted into a horizontal airflow and sprayed by the ring air jet. The hollowed gastrodia elata hovering in the annular upward airflow is effectively blown out, and the screening efficiency is improved.

[0022] 3. By setting the annular air bag, the vertical sliding bar and the vertical sliding groove, the annular air bag is used to effectively reduce the impact of the hollowed gastrodia elata blown out by the return assembly on the inner wall of the outer cylinder. The vertical sliding bar and the vertical sliding groove are set to realize the convenient fixing and installation of the annular air bag, and improve the maintenance efficiency.

[0023] 4. By setting the motor one, the gear, the inner inclined slope ring, the outer tooth ring and the discharge box, the motor one drives the gear to rotate the outer tooth ring, realizes the circular motion of the discharge box, quickly and uniformly discharges the gastrodia elata in the discharge box, and improves the discharge speed and the utilization rate of the annular upward airflow sprayed by the inner ring opening.

[0024] 5. By setting the slope box, inner groove, rubber barrier block, spring column, motor two and cross head, the cross head is driven to rotate by the motor two, so as to magnetically attract and pull the spring column and the rubber barrier block, realize the opening and closing of the interval space between the two slope boxes in the discharge box, control the discharge rhythm of the gastrodipsis, and ensure that the gastrodipsis can adapt to the discharge box of the annular movement.

7. The ginseng screening device for breeding of claim 1, wherein, A lower discharge pipe (13) is fixedly mounted on the bottom end of the funnel plate (5), and a plurality of flexible hair rings (14) are equidistantly mounted on the inner wall of the lower discharge pipe (13).

8. The ginseng screening device for breeding of claim 1, wherein, Half-circle material boxes (15) are arranged on the bottom left and right sides of the outer cylinder (7), and the half-circle material boxes (15) are placed on the top of the outer wall protrusions of the inner cylinder (2). The bottom of the inner cylinder (2) is provided with a material receiving box (16), and the material receiving box (16) is placed on the top middle of the base (1).

9. A method for breeding Gastrodia elata, characterized by, The ginseng screening device for breeding comprises the following steps: S1, ginseng discharging: first, the ginseng is sent into the discharge assembly (12) to continuously discharge the ginseng in a circular motion, and the discharged ginseng then enters the upward airflow released by the inner cylinder (2) to start the screening process of hollowed ginseng; S2, screening ginseng: continuing the step S1, the ginseng is further classified in the upward airflow released by the inner cylinder (2), the normal ginseng is not affected by the upward airflow and falls downward due to its own weight, and the hollowed ginseng remains in a hovering state in the upward airflow due to its lighter weight; S3, hollowing removal: the upward airflow discharged by the inner cylinder (2) is returned by the return assembly (11) and is converted into a horizontal circular airflow, the hollowed ginseng hovering in the upward airflow is blown out by the circular airflow, the blown-out hollowed ginseng falls into the space between the inner cylinder (2) and the outer cylinder (7), and the buffer assembly (9) is used to avoid the impact of the blown-out hollowed ginseng on the inner wall of the outer cylinder (7), and then the hollowed ginseng falls into the half-circle material box (15) at the bottom of the outer cylinder (7) for collection; S4, good product collection: the normal ginseng falls into the funnel plate (5) and rolls down, is cleaned and buffered by the lower discharge pipe (13) provided with flexible hair rings (14), the falling speed is slowed down to reduce damage, and finally falls into the material receiving box (16) at the bottom of the lower discharge pipe (13) for collection.
