In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0028] Refer to the attached Figures 1 to 5 As shown, the embodiment of the present application provides a new type of seed drill, including a seed tray and a seed drill body. The seed drill body has a seed rack for installing the seed tray. The seed drill body, the rack, and the installation of the seed tray and the rack are all existing technologies. Please refer to the existing Maschio DAMA type mechanical combined seed drill, which will not be described here.

[0029] In the above, the seeding disc includes a seed chamber disc 7, a seeding disc 1 and an air chamber disc 8. The seeding disc 1 is arranged between the seed chamber disc 7 and the air chamber disc 8 and is rotatable. Among them, a positioning shaft through hole 701 is provided in the center of the seed chamber disc 7, and a hexagonal positioning mounting hole 5 is provided in the center of the seeding disc 1. When the seeding disc is installed, the seed chamber disc 7 is fixed integrally with the seeding rack, and the seeding rack is provided with a hexagonal rotating shaft for driving the seeding disc 1 to rotate. The hexagonal rotating shaft passes through the positioning shaft through hole 701 and is inserted into the hexagonal positioning mounting hole 5. The seeding disc 1 can be driven to rotate by the hexagonal rotating shaft. The seeding disc 1 is connected to the hexagonal rotating shaft by using the hexagonal positioning mounting hole 5. It can transmit power stably, is quick and convenient to install, and does not lose rotation speed. At the same time, if Figure 4 As shown, the interior of the seed chamber disk 7 is divided into a mutually independent feed chamber 703 and discharge chamber 704 by a curved partition. The feed chamber 703 is provided with a feed port 702, and the bottom of the discharge chamber 704 is provided with a discharge port 705. The seeding device sends the seeds into the feed chamber 703 from the feed port 702, and the sowing disc 1 brings the seeds from the feed chamber 703 into the discharge chamber 704, and the seeds are discharged from the discharge port 705 to complete the sowing.

[0030] Among the above, Figure 2 and Figure 3 As shown, a plurality of seed suction holes 101 are arranged in a circumferential array on a certain radial circumference of the sowing disc 1. A plurality of replaceable seed screen sleeves 2 are provided in the seed suction holes 101. The seed screen sleeves 2 have sleeve holes 201 adapted to the particle size of the seeds to be sown. Here, the adaptation of the sleeve holes 201 to the particle size of the seeds to be sown should be understood as the diameter of the sleeve holes 201 being equal to or slightly larger than the particle size of the seeds to be sown. Thus, during the sowing process, as the sowing disc rotates, under the action of the negative pressure in the seed discharge suction chamber, the seed suction holes 101 can absorb a seed onto the seed screen sleeve 2. An annular trough is provided on the radial circumference where the seed suction holes 101 are located. The seed suction holes 101 are arranged at equal intervals along the annular trough, and the sowing disc 1 is provided with a discharge notch 6 from the outer circumference to the annular trough.

[0031] It can be seen that the new type of seeder provided by the embodiment of the present application, by setting a seed screen sleeve 2 adapted to the seeds to be sown in the seed suction hole 101, can select the appropriate seed screen sleeve 2 to be replaced and installed in the seed suction hole 101 according to the different seeds to be sown, so that the sowing tray can sow different types of seeds, thereby greatly improving the versatility of the sowing tray.

[0032] In the above, the seed screen sleeve 2 includes a large diameter section and a small diameter section. The large diameter section and the small diameter section have sleeve holes 201 with the same aperture. The large diameter section and the small diameter section are integrally formed of rubber material. The small diameter section is inserted into the seed suction hole 101 and is sealed in the seed suction hole 101 by utilizing its plastic elasticity. The large diameter section fits onto the disc surface of the sowing disc 1, making it convenient to insert and remove the seed screen sleeve 2.

[0033] Others, such as Figure 3As shown, the seeding disc 1 is also provided with a plurality of stirring claws 3 arranged circumferentially along its radial circumference. These stirring claws 3 are located closer to the center of the disc 1 than the seed suction holes 101. During the seeding process, as the disc rotates, the stirring claws 3, evenly distributed along the circumference, stir the seeds in the feed chamber 703 into a loose state, allowing the seeds to be attracted to the seed screen 2 as single grains. Of course, due to the diameter of the disc, the optimal number of seed suction holes 101 is 12-20. Since the stirring claws 3 are located closer to the center of the disc, the optimal number of stirring claws 3 is 8-16.

[0034] In this embodiment, if Figure 5 As shown, a negative pressure chamber is provided in the air chamber disc 8, and the air chamber disc 8 is equipped with an air chamber tube 801 for connecting to the negative pressure structure of the seeder. The air chamber tube 801 extends into the negative pressure chamber, and a number of air holes are provided on the side wall of the air chamber tube 801 extending into the negative pressure chamber, so that the negative pressure is connected to the negative pressure chamber. A seed stripping disc is provided at one end of the air chamber tube 801 located in the negative pressure chamber. The diameter of the seed stripping disc is smaller than the inner diameter of the negative pressure chamber, so that negative pressure can be generated in the negative pressure chamber so that the seeds are adsorbed onto the seed screen sleeve 2. The seed stripping disc is located on one side of the discharge chamber 704 and is provided with an annular protrusion 803 corresponding to the annular groove. When the seeding disc rotates to one side of the discharge chamber 704, the annular protrusion 803 scrapes the seeds adsorbed on the seed screen sleeve 2 into the discharge chamber 704, and is discharged from the discharge port 705 to complete the sowing.

[0035] To sum up, the embodiment of the present application provides a new type of seeder. During sowing, the seeds are fed into the feed chamber 703 through the seed meter. The rotating sowing disc 1 uses the seed stirring claws 3 to break the seeds into granules. The external negative pressure device on one side of the negative pressure chamber generates negative pressure to adsorb the seeds into the inside of the seed screen sleeve 2 adapted thereto and enter the annular groove 4. As the sowing disc 1 is transferred from the feed chamber 703 to the discharge chamber 704, it is scraped off by the annular protrusion 803 on one side of the discharge chamber 704 and falls into the discharge chamber 704 from the discharge notch 6, and is discharged from the discharge port 705 to complete the sowing.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
