A first slot is provided on the side of the delivery channel 6 facing the seed box 1, a seed spoon inlet 7 is provided on the upper end of the arc-shaped delivery channel 6, a seed outlet 8 and a seed spoon outlet 16 are provided on the lower end, baffles 9 are provided on the outer sides of the outermost disks 4 at both ends of the rotating shaft 3, a partition 10 is provided between two adjacent disks 4, a second slot 11 is provided on the partition 10, the first slot is aligned with the second slot and is used for the rotation of the disk 4, a material trough 12 is provided on the side of the partition 10 close to the seed box 1, and the material trough 12 is located below the outlet.

[0026] In order to ensure the even distribution of seeds in the trough 12 and prevent the situation where some seed spoons 5 cannot get seeds during sowing, in the present embodiment, the trough 12 includes a plurality of directly arranged hoppers 12-1, the number of hoppers 12-1 is consistent with the number of discs 4, and the inner wall of the hopper 12-1 is inclined inwardly.

[0027] In order to improve the structural strength of the seed box 1 and to preliminarily achieve the effect of evenly distributing the material, in the present embodiment, a plurality of cross beams 13 are provided above the discharge port to divide the discharge port into a plurality of sections, and the number of the divisions is consistent with the number of the hoppers 12-1.

[0028] In order to play a sealing role and prevent the seed material from falling out, in this embodiment, a limiting plate 17 is rotatably provided on the upper part of the material trough 12, and a rotating rod 14 is provided on the upper end of the limiting plate 17. Both ends of the rotating rod 14 are arranged through the baffle 9, and a driving mechanism 15 is connected to one side of the rotating rod 14. In this embodiment, the driving mechanism 15 includes a pull rod 15-1 and a connecting arm 15-2, the lower end of the connecting arm 15-2 is fixedly connected to the rotating rod 14, one end of the pull rod 15-1 is rotatably connected to the operating lever 15-3, and the other end is rotatably connected to the upper end of the connecting arm 15-2.

[0030] The working principle of the above technical solution is:

[0031] When in use, the first step is to select seed spoons 5 of different specifications according to the size of the seeds to be sown, and connect them to the spoon body 5-1 by screws. If the size of the spoon body 5-1 is suitable, there is no need to nest seed spoons 5 of other specifications. The technical solution provided by the utility model can be used for the sowing of crops such as Fritillaria, garlic, and Corydalis; the second step is to pour the seeds to be sown into the material box; the third step is to start the carrier to drive the seed-taking mechanism provided in this embodiment to move in the field, and the power output device of the carrier drives the rotating shaft 3 to rotate through a gear, chain, or belt transmission, thereby driving the disc 4 to rotate. When the disc 4 rotates again, the seed spoon 5 digs the seeds onto the spoon body 5-1, thereby driving the seeds into the arc-shaped conveying channel 6. Under the action of the seed spoon 5 and gravity, the seeds fall out of the seed outlet 8 into the pipeline, and finally fall into the groove opened by the furrow opener set at the bottom of the seeder.

[0032] During use of this embodiment, the opening and closing degree of the limiting plate 17 can be adjusted by pulling the operating lever 15 - 3 , thereby adjusting the falling speed of the seed material in the seed box 1 .

[0033] Compared with the prior art, the beneficial effects of the utility model are:

[0034] 1. The utility model adopts the method of installing the seed spoon 5 on the side of the rotating disc 4 to avoid the defect of the existing method of installing the seed spoon 5 on the chain, which easily causes the chain to clamp the seed material, prevents the seed material from being damaged, and improves the reliability of the equipment.

[0035] Second, the utility model can nest spoon bodies 5-1 of different specifications on the seed spoon 5 according to needs to meet the sowing of seeds of different sizes, and has good applicability.

[0036] 3. The setting of the adjustable material limiting plate 17 of the utility model can effectively prevent the seed material from piling up in the material trough 12 and affecting the normal material taking operation, thereby increasing the service life and reliability of the equipment and improving the work efficiency.
