[0002] Sowing is an essential part of agricultural production. Traditionally, sowing is done manually, which is time-consuming and labor-intensive. Seeders require seed metering before sowing, but existing seed metering devices cannot adjust the amount of seeds dispensed, resulting in seed waste or insufficient sowing requiring secondary sowing by workers, greatly reducing work efficiency. Furthermore, seeds tend to accumulate in the funnel of existing seed metering devices, causing missed sowing, which requires manual re-sowing, affecting sowing efficiency. To address these issues, a precision seed metering device for seeders is needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] For an example, please refer to... Figure 1-5 This utility model provides a technical solution:

[0026] In this embodiment, reference Figure 1 , Figure 2 and Figure 3The stirring and seeding structure 3 includes a drive motor 301, which is connected to the inner cavity of the connecting housing 1 via a connecting seat. The drive end of the drive motor 301 is connected to a drive rod 302 via a coupling. A driven helical gear 304 is meshed with a drive helical gear 303 on the side wall of the drive rod 302. A rotating rod 305 is connected to the center of the driven helical gear 304. An stirring blade 306 is connected to the side wall of the rotating rod 305 and located in the inner cavity of the stockpiling bin 2. A drive sprocket 307 is symmetrically connected to the side wall of the rotating rod 305. A driven sprocket 309 is meshed with a drive chain 308 on the side wall of the drive sprocket 307. A connecting rod 310 is connected to the center of the driven sprocket 309.

[0027] Based on the above structure and the connection relationship of the above structure, the drive motor 301 is controlled by the controller 5 to run. When the drive end of the drive motor 301 rotates, it sequentially drives the drive rod 302, the drive helical gear 303, the driven helical gear 304, the rotating rod 305 and the stirring blade 306 to rotate. When the rotating rod 305 rotates, it sequentially drives the drive sprocket 307, the drive chain 308, the driven sprocket 309 and the connecting rotating rod 310, so that the loading groove 401 on the side wall of the stirring blade 306 and the connecting rotating rod 310 can be rotated at the same time.

[0028] Furthermore, the drive motor 301 is connected to the controller 5 via wires in an electrical connection manner, and the operation of the drive motor 301 can be controlled by the controller 5.

[0029] Furthermore, the drive rod 302 is connected to the inner cavity of the connecting housing 1 through a bearing seat, wherein the drive rod 302 and the bearing seat are connected by a rotatable connection. The rotating rod 305 is connected to the side wall of the connecting housing 1 through a bearing seat, wherein the rotating rod 305 and the bearing seat are connected by a rotatable connection. The connecting rotating rod 310 is connected to the side wall of the connecting housing 1 through a bearing seat, wherein the connecting rotating rod 310 and the bearing seat are connected by a rotatable connection. When the drive rod 302 rotates, it can drive the stirring blade 306 to rotate.

[0030] In this embodiment, reference Figure 1 , Figure 2 , Figure 4 and Figure 5The adjustable quantitative structure 4 includes multiple sets of the same number of loading slots 401 and shielding slots 402. The loading slots 401 and shielding slots 402 are staggered on the side wall of the connecting rotating rod 310. An adjusting rod 403 is connected to the inner cavity of the shielding slot 402. One end of the adjusting rod 403 is connected to a rotating knob 404. The other end of the adjusting rod 403 and located on the side wall of the shielding slot 402 is connected to a shaft retainer 405. Multiple sets of guide slides 406 are opened on the side wall of the adjusting rod 403. A connecting lever 407 is provided in the guide slide 406. One end of the connecting lever 407 is connected to a moving partition 408 in the loading slot 401 through a connecting ring. A limiting slide 409 is connected in the shielding slot 402 and on the moving partition 408.

[0031] Based on the above structure and the connection relationship of the above structure, by rotating the adjusting rod 403 with a wrench, when the adjusting rod 403 rotates, the moving partition 408 is driven to slide on the side wall of the limiting slide rod 409 through the guide slide 406 and the connecting lever 407, thereby adjusting the distance between multiple sets of moving partitions 408.

[0032] Furthermore, the adjusting rod 403 is connected to the side wall of the inner cavity of the shielding groove 402 via a bearing seat. The adjusting rod 403 is rotatably connected to the bearing seat. The rotating knob 404 has a regular hexagonal cross-section. The guide slide 406 and the connecting lever 407 are fitted with clearance. Slide grooves are provided on the side walls of the loading groove 401 and the shielding groove 402, corresponding to the movable partition 408. The movable partition 408 is slidably connected to the slide groove. Slide grooves are also provided on the movable partition 408, corresponding to the limiting slide rod 409. The limiting slide rod 409 is slidably connected to the slide groove. When the adjusting rod 403 rotates, the distance between multiple sets of movable partitions 408 can be adjusted.

[0033] The working process of this utility model is as follows: When using the precision seed metering device for a seeder, first connect the device to the power supply so that the device is in working condition. Then, load the seeds into the stacking bin 2. Then, according to the needs of use, turn the adjusting rod 403 with a wrench. When the adjusting rod 403 is turned, it drives the moving partition 408 to slide on the side wall of the limiting slide rod 409 through the guide slide 406 and the connecting lever 407, thereby adjusting the distance between multiple sets of moving partitions 408, so as to accurately control the number of seeds metered by the seed metering device.

[0034] Finally, the controller 5 controls the operation of the drive motor 301. When the drive end of the drive motor 301 rotates, it drives the drive rod 302 to rotate. The drive rod 302 drives the drive helical gear 303 to rotate. The drive helical gear 303 drives the driven helical gear 304 to rotate. The driven helical gear 304 drives the rotating rod 305 to rotate. The rotating rod 305 drives the stirring blade 306 to rotate. When the rotating rod 305 rotates, it drives the drive sprocket 307 to rotate. The drive sprocket 307 drives the drive chain 308 to rotate. The drive chain 308 drives the driven sprocket 309 to rotate. The driven sprocket 309 drives the connecting rotating rod 310 to rotate. This allows the drive motor 301 to rotate simultaneously after starting the drive motor 301. The loading trough 401 on the side wall of the stirring blade 306 and the connecting rotating rod 310 can rotate at the same time. This makes the seeds in the stockpile 2 more fluid, improves the loading rate of the seeds in the loading trough 401, and improves the accuracy of the seed metering device during seed metering.
