The utility model discloses a working process:

ginseng seeds are stored in a seed box 2-7, a driving device 6 drives a driving wheel 5 to rotate through a chain transmission mechanism I7, the driving wheel 5 drives the whole seeding device to move forward in the field in the seeding process, the rotating driving wheel 5 drives a ditching wheel shaft 4-1 to rotate through a chain transmission mechanism II 8, the ditching wheel shaft 4-1 drives a ditching wheel hub 4-2 arranged on the ditching wheel shaft to rotate in the rotating process, the ditching wheel hub 4-2 drives a ditching cutter wheel 4-3 arranged on the ditching wheel hub to rotate, and the ditching cutter wheel 4-3 presses 28 seed ditches on a ridge bed in the field in the rotating process. The rotating driving wheel 5 drives the brush wheel shaft 2-5 to rotate through the chain transmission mechanism III 9, the brush wheel shaft 2-5 drives the brush wheel 2-10 arranged on the brush wheel shaft to rotate, meanwhile, the brush wheel shaft 2-5 drives the seed shaft 2-4 to rotate through the chain transmission mechanism IV 2-8, the seed shaft 2-4 drives the seed wheel 2-1 arranged on the seed shaft to rotate, the seed wheel 2-1 is in a rotating process, the protrusions 2-1-2 in an arc structure on the seed box 2-7 disturb the ginseng seeds in the seed box 2-7, so that the ginseng seeds can flatly lie down to enter the seed hole 2-1-1 under the combined action of the self gravity and the disturbing middle acting force, when the seeds entering the seed hole 2-1-1 reach the position of the brush wheel 2-10 along with the rotation of the seed wheel 2-1, the brush hair on the brush wheel 2-10 brushes away the seeds which are filled into the seeding hole 2-1-1, and only one seed is left in the seeding hole 2-1-1. When the brush wheel 2-10 rotates to the front side baffle of the seed box 2-7, the front side baffle of the seed box 2-7 clears away the seeds embedded in the brush of the brush wheel 2-10, and the seeds are prevented from being scattered outside the seed box 2-7 by the brush wheel 2-10 in the rotating process. With the continuous rotation of the seed discharging wheel 2-1 on the seed discharging shaft 2-4, after passing through the brush wheel 2-10, the seeds entering the seed discharging holes 2-1-1 enter a seed protecting area formed by the flexible seed protecting plate 2-11, the seeds placed by the flexible seed protecting plate 2-11 fall from the seed discharging holes 2-1-1 without reaching the seeding area, when the seeds entering the seed discharging holes 2-1-1 leave the seed protecting area formed by the flexible seed protecting plate 2-11, the seeds enter the seeding area, and the seeds fall from the seed discharging holes 2-1-1 under the action of self gravity, and then fall from an opening at the bottom of the seed box 2-7 into a seed ditch formed by the ditching wheel 4, so that the seeding is completed.

The utility model aims at the intensive seeding mode of ginseng planting, under the premise of ensuring the seeding density, the uniform grain distance and the consistent seeding depth are realized, the adaptability to the geometric shape and the size of ginseng seeds is strong through the innovative design of the seeding apparatus, the designed ditching wheel can realize the narrow-row ditching requirement of ginseng planting, and the precision dibbling is realized; meanwhile, the damage to the germination accelerating ginseng seeds in the sowing process is avoided, the seed utilization rate is improved, the labor force is saved, and the expenditure cost of ginseng growers is saved.

Finally, it is noted that the above-mentioned embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
