An eccentrically arranged locking hole 13 is provided on the left side of the main disc. The outer ring 2 is of a circular hollow structure, the inner side wall of the outer ring is in contact with the cylindrical outer wall of the main disc, and the outer ring and the main disc rotate relatively. A plurality of seeding nozzles 3 are uniformly fixed on the outer ring along the circumferential direction, and the seeding nozzles are arranged along the radial direction of the outer ring. The seeding mouth is hinged with a movable mouth 31, a torsional spring is arranged between the movable mouth and the seeding mouth, the movable mouth and the seeding mouth are clamped tightly under the action of the torsional spring, and the movable mouth is arranged on the inner side of the seeding mouth. One end of the seeding nozzle extending out of the outer ring is conical so as to be convenient for inserting into soil. One end of the seeding nozzle extending into the inner side of the outer ring is contacted with the cylindrical outer wall of the main disc, as shown in fig. 9, a seed channel 15 which is obliquely arranged is arranged on the main disc and penetrates through the inner side wall and the outer side wall of the main disc. The relative main disc of outer ring is rotatory, and after the seeding mouth adjusted well with kind, the seed in kind can slide in the seeding mouth. The shifting wheel 32 is arranged on the outer side of the main disc, the shifting wheel is fixedly connected with the movable nozzle, teeth are arranged on the shifting wheel, and after the shifting wheel is contacted with the second end of the driving rod, the driving rod can drive the shifting wheel to rotate, so that the movable nozzle rotates relative to the seeding nozzle, the seeding nozzle is opened, and seeds in the seeding nozzle fall into the seed hole at the moment.

As shown in fig. 1 and 3, a seed storage groove 14 is arranged on the main disc, and an opening of the seed storage groove 14 is communicated with the inner cavity of the main disc. The seed storage groove is communicated with a seed inlet 16 on the front side wall of the main disc, seeds enter the main disc through the seed inlet and then enter the seed storage groove, and the seed taking mechanism takes out the seeds in the seed storage groove. As shown in fig. 2 and 3, the seed taking mechanism comprises a seed taking wheel 4 rotatably mounted on the inner side of the main disc, a sun gear 62 fixedly connected with the seed taking wheel, a gear ring 6 fixedly connected with an outer ring, and a plurality of planet gears 61 arranged between the gear ring and the sun gear, wherein the planet gears are rotatably connected with the main disc, and when the outer ring rotates, the outer ring can drive the gear ring to rotate, so that the planet gears are driven to rotate, and then the sun gear is driven to rotate. Thereby driving the seed-taking wheel to rotate. As shown in fig. 7, a seed taking groove 41 is provided on the cylindrical outer wall of the seed taking wheel, a plurality of partition plates 42 are provided in the seed taking groove, the partition plates divide the seed taking groove into a plurality of independent seed taking cavities, and the seed taking cavities can only contain a fixed number of seeds, such as one seed, two seeds, etc. When the seed taking wheel is rotated to the state that the seed taking groove is communicated with the opening of the seed storage groove, the seeds in the seed storage groove 14 enter the seed taking cavity as shown in figure 9. As shown in fig. 10, with the continued rotation of the seed-taking wheel, the seed-taking cavity moves to communicate with the seed channel, and the seeds 7 in the seed-taking cavity can enter the seed channel under the self-weight. The gear ring, the planet gear and the central gear form a linkage unit which drives the seed taking wheel to rotate along with the outer ring.

For avoiding the inconsistent seeding depth that leads to because of soil surface unevenness, be fixed with on the master plate and smooth the mechanism, as shown in fig. 5, smooth the mechanism and include the articulated installation pole 5 of being connected with the master plate, set up the bolt 51 between installation pole and master plate, with the articulated scraper blade 52 of being connected of installation pole, the first end and the master plate of installation pole are articulated to be connected, the bolt will be installed the pole and the master plate is fixed together, and then make the installation pole keep fixed inclination. The second end of the installation rod is provided with an ear plate 53, the scraper plate is also provided with the ear plate 53, the ear plate on the scraper plate is hinged with the ear plate on the installation rod, a torsion spring is arranged between the scraper plate and the installation rod, and the scraper plate is in end face contact with the second end of the installation rod under the action of the torsion spring. As shown in fig. 4, when the seeding disc moves forward, the scraper contacts with the soil on the surface of the field 9, and at this time, the scraper swings counterclockwise by a certain extent, so as to strike off the soil surface. After the uneven field surface is strickled off, the uniformity of the sowing depth can be realized. As shown in fig. 6, for the convenience of storage, an expansion link 55 may be slidably mounted in the mounting rod, and the scraper may be mounted at the end of the expansion link, and a bolt may be provided between the expansion link and the mounting rod to realize locking and fixing therebetween. The setting of telescopic link can realize the regulation of scraper blade position, and then adjusts the ability of strickleing off of scraper blade. The mounting rod is provided with a positioning hole 54, and a bolt penetrates into the positioning hole to realize locking and fixing of the mounting rod and the main disc.

When the ground surface is hard, in order to ensure that the depth of the sowing nozzles extending into the soil meets the requirement, as shown in fig. 11 and 12, an end cover 21 is installed on the cylindrical outer wall of the outer ring in a threaded mode, and the end cover is positioned between two adjacent sowing nozzles. A handle 22 is provided on the end cap to facilitate mounting and dismounting between the end cap and the outer ring. When the ground is hard, as shown in fig. 13, the end cap is removed and soil 8 is added to the inner cavity of the outer ring to increase the overall weight and facilitate insertion of the seeding nozzle into the soil.

The improved seeder has a simple structure, and the ground is scraped through the flattening mechanism, so that the inconsistency of seeding depth caused by the unevenness of the ground is avoided; get the setting of kind of mechanism, can realize accurately getting kind of and the transfer of seed, realize evenly seeding with the seeding mouth cooperation.
