[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1-2 A novel single-unit seed metering device for a seeder includes a fixed frame 1 and a seed guide groove 2. The seed guide groove 2 is fixedly installed at the bottom end of the fixed frame 1. The device also includes a seed metering component 3, an air-tightening component 4, and a connecting component 5. The seed metering component 3 is fixedly installed on the fixed frame 1. The air-tightening component 4 is fixedly installed on the seed metering component 3, and the connecting component 5 is installed at the end of the air-tightening component 4.

[0022] The seed metering assembly 3 has a feed inlet 302 at the end of the seed metering housing 301 and a seed tray 303 at the inner end of the seed metering housing 301.

[0023] In use, seeds enter the seed tray 303 inside the seed metering device housing 301 through the feed inlet 302. The seed tray 303 rotates, precisely guiding the seeds to fall into the seed guide groove 2 along a predetermined trajectory. Subsequently, the seeds fall into the seed furrow through the seed guide groove 2, achieving uniform distribution, ensuring appropriate plant and row spacing, reducing missed sowing and double sowing, improving sowing quality and land utilization, and benefiting crop growth and later management and harvesting. At the same time, different types of seeds, regardless of size, can enter smoothly, reducing jamming and blockage during the seed guiding process and enhancing adaptability to different crop seeds.

[0024] Example 2: Based on Example 1, please refer to... Figures 2-3 The seed tray 303 in the seed metering assembly 3 is provided with a seed tray sealing ring 304 on one end, and the seed tray 303 is fixedly mounted on the seed tray support 305.

[0025] The fastening head 401 in the air-tightening component 4 is fixedly mounted on the seed tray 303, and the other end of the fastening head 401 is provided with an air-tightening end 402, which is fixedly mounted on the seed tray support 305.

[0026] During use, the seed tray sealing ring 304 ensures the sealing of the seed tray 303, reducing the risk of seed leakage. The fastening head 401 and the air-sealing end 402 of the air-sealing component 4 work together to ensure stable air pressure inside the seed metering component 3, which facilitates the accurate discharge of seeds under the action of the seed tray 303. The seeds move in the smooth seed guide groove 2 with minimal collision and friction with the groove wall, effectively reducing damage caused by collision and friction, ensuring seed integrity, and improving seed germination rate and seedling growth.

[0027] Example 3: Based on Example 2, please refer to... Figures 3-4 The seed metering bearing 501 in the connecting assembly 5 is fixedly provided with a seed metering chain plate 502 at its end, and the seed metering chain plate 502 is fixedly connected by fastening screws 503.

[0028] The other end of the seed metering chain plate 502 in the connecting component 5 is fixedly mounted on the seed metering mounting base 504, and the seed metering mounting base 504 is fixedly connected to the seed metering housing 301 by screws.

[0029] During use, the seed metering bearing 501 drives the seed metering chain plate 502 to operate, ensuring the stable operation of the seed metering assembly 3. The entire seed metering structure is installed inside the seed metering mounting base 504, making installation and disassembly convenient. This reduces the overall structural complexity of the seeder, facilitates maintenance and upkeep, and ensures good stability during operation, reducing the likelihood of malfunctions. It effectively improves the efficiency of the seeder and shortens the sowing time. Especially in large-scale agricultural production, it can accelerate the sowing progress and ensure timely planting. At the same time, the seeds can be accurately introduced into the prepared seed furrows, making full contact with the soil, which is conducive to the absorption of water and nutrients, creating a good soil environment. Combined with the soil covering device, the soil covering is even, further conserving moisture and fertilizer, and promoting crop growth. Moreover, the integrated design reduces the number of parts, lowers manufacturing and procurement costs, and improves sowing accuracy and efficiency, reducing seed waste and reseeding costs. Overall, it reduces agricultural production costs and improves economic benefits.
