[0002] The seed tray is a key working component of the seed metering device on an air-suction grain seeder, directly affecting the seeding performance and effectiveness of the air-suction seeder.

[0003] Currently, different seeding trays need to be set up according to different seeds, and seed suction holes adapted to the seed particle size need to be set on the seeding trays. This results in low versatility of seeding trays and increased investment costs for agricultural machinery users. Utility Model Content

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0023] See attached document Figure 1 This application provides a seeding disc for a seeder, including a seeding disc 1. A hexagonal positioning mounting hole 5 is provided at the center of the seeding disc 1. The seeding disc 1 is connected to the seeder's rotating shaft through the hexagonal positioning mounting hole 5, ensuring stable power transmission, quick and convenient installation, and no loss of rotational speed. A plurality of seed suction holes 101 are arranged in a circumferential array on a radial circumference of the seeding disc 1. A plurality of replaceable seed sieve sleeves 2 are provided within the seed suction holes 101. The seed sieve sleeves 2 have apertures 201 adapted to the particle size of the seeds to be sown. Here, "adapted to the particle size of the seeds to be sown" should be understood as the diameter of the aperture 201 being slightly smaller than the particle size of the seeds to be sown. Therefore, during the sowing process, as the seeding disc rotates, under the negative pressure of the seed discharging suction chamber, the seed suction hole 101 picks up a seed onto the seed sieve sleeve 2. When the seed suction hole 101 rotates out of the suction chamber, the negative pressure disappears, and the seed falls freely along the seed guide tube of the seed metering device, completing one sowing process.

[0024] As described above, the seed sieve sleeve 2 includes a large-diameter section and a small-diameter section. The large-diameter section and the small-diameter section have the same aperture 201. 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 its plastic elasticity. The large-diameter section fits the disc surface of the seeding disc 1, making it convenient to insert and remove the seed sieve sleeve 2.

[0025] In a preferred embodiment, such as Figure 1As shown, the sowing disc 1 also has several seed-stirring claws 3 arranged circumferentially on its radial circumference. The seed-stirring claws 3 are closer to the center of the sowing disc 1 than the seed suction holes 101. During the sowing process, as the sowing disc rotates, the seed-stirring claws 3, evenly distributed along the circumference, stir the seeds in the seed filling chamber into a loose state, so that the seeds can be adsorbed into the seed sieve sleeve 2 in the form of individual seeds. Of course, due to the limitation of the diameter of the sowing disc, the optimal number of seed suction holes 101 is 12-20, and since the seed-stirring claws 3 are closer to the center, the optimal number of seed-stirring claws 3 is 8-16.

[0026] In addition, to create a better negative pressure on the seeding disc 1, see [link to relevant documentation]. Figure 1 As shown, an annular groove is provided on the radial circumference of the seed suction hole 101. The annular groove enables the air suction chamber to form a negative pressure airflow on the surface of the seeding disc 1, which facilitates the formation of a good negative pressure to adsorb seeds in the seed suction hole 101.

[0027] In summary, the embodiments of this application provide a seeding tray for a seeder. By setting a seed sieve sleeve adapted to the seed to be sown in the seed suction hole, and selecting and replacing the appropriate seed sieve sleeve in the seed suction hole according to the different seeds to be sown, the seeding tray can sow different types of seeds, greatly improving the versatility of the seeding tray.

[0028] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
