Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an air-blowing seed metering device. Background Technology

[0002] In agricultural production, seeders are crucial planting equipment, enabling large-scale operations to be completed in a short time. Moreover, seeding machinery not only improves planting efficiency and production benefits but also reduces planting costs and soil pollution and damage. Simultaneously, the use of seeders saves human resources, allowing farmers to focus more on crop planting and management, thus increasing their labor productivity and income levels. Furthermore, the development of seeders can further promote agricultural mechanization and accelerate the modernization of agriculture. With the development of social productivity, the application of mechanization will have even broader prospects for development in the future.

[0003] Grains are one of the important food sources for mankind. With the development of technology, people's demand for efficient sowing is increasing. However, the sowing effect of most seed metering devices is difficult to guarantee, and blockages may occur and are difficult to clean, which is not conducive to related agricultural planting work. Summary of the Invention

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] To achieve the above objectives, the first aspect of this utility model proposes an air-blowing seed metering device, comprising: a housing, an air inlet, a seed metering disc, a rubber roller, a seed cleaning wheel, an adjusting handle, and a seed scraper roller. The air inlet is located on one side of the housing. The seed metering disc is rotatably disposed within the housing, and a seed suction hole is circumferentially arranged on the seed metering disc. The rubber roller and the seed cleaning wheel are both rotatably disposed within the housing and located beside the seed suction hole. The adjusting handle is connected to the seed scraper roller, which is disposed inside the housing and coaxial with the seed suction hole.

[0006] In addition, the air-blowing seed metering device proposed above according to this utility model may also have the following additional technical features:

[0007] Furthermore, a baffle is provided on the housing to block the feeding port.

[0008] Furthermore, a cleaning plate is provided on the housing to facilitate subsequent cleaning.

[0009] Furthermore, the housing is provided with a discharge port for discharging materials.

[0010] Furthermore, the seed scraper roller is disposed within the housing via a spring plate.

[0011] According to the present invention, the air-blowing seed metering device drives the seed metering disc through air pressure. The rubber roller can seal the seed metering disc to ensure the integrity of the device. The seed cleaning wheel can clean the seed metering disc to avoid clogging. The position of the seed scraper roller can be adjusted by adjusting the handle to scrape off excess seeds and ensure planting effect.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The air-blowing seed metering device of this utility model is described below with reference to the accompanying drawings.

[0020] like Figures 1 to 2 As shown, the air-blowing seed metering device of this utility model embodiment may include a housing, an air inlet 1, a seed metering disc 2, a rubber roller 3, a seed cleaning wheel 4, an adjusting handle 5, and a seed scraper roller 6.

[0021] The shell is equipped with a baffle 7 to block the feeding port, a cleaning plate 8 for easy cleaning, and a discharge port 9 for discharging materials.

[0022] It should be noted that the baffle 7, cleaning plate 8, and discharge port 9 can perform loading and unloading and cleaning work inside the shell, ensuring the integrity of the device.

[0023] Air inlet 1 is located on one side of the housing.

[0024] It should be noted that air inlet 1 is connected to a high-speed fan to facilitate the introduction of air pressure.

[0025] The seed metering disc 2 is rotatably mounted inside the housing, and seed suction holes are provided around the circumference of the seed metering disc 2.

[0026] It should be noted that the seed suction hole facilitates the seed metering disc 2 for seed metering.

[0027] Both the rubber roller 3 and the seed cleaning roller 4 are rotatably mounted inside the housing and are located next to the seed suction hole.

[0028] It should be noted that the rubber roller 3 and the seed cleaning roller 4 can be used for sealing and cleaning respectively, which is convenient for use.

[0029] The adjusting handle 5 is connected to the seed scraper roller 6, which is set inside the housing by a spring plate and is on the same axis as the seed suction hole.

[0030] It should be noted that the connection via spring plates prevents the seed scraper roller 6 from sticking too tightly to the seed metering disc 2, reducing wear on the seed metering disc and ensuring its service life. Furthermore, the seed scraper roller 6 maintains a suitable gap with the seed metering disc under the force of the spring plates to prevent seed jamming. At the same time, the appropriate elasticity ensures relative movement between the roller and the seed metering disc 2, ensuring one seed per hole and reducing the replanting rate.

[0031] Specifically, when relevant personnel need to carry out relevant sowing work, they can first open the baffle 7 to add seeds into the shell, and then add air pressure into the air inlet 1 through the fan, thereby driving the seed metering disc 2 to rotate. Under a certain air pressure, the seeds are adsorbed onto the seed metering disc 2, and the seeds will be rotated together with the seed metering disc 2.

[0032] The greater the air pressure inside the shell, the stronger the ability of the seed metering disc 2 to adsorb seeds and the lower the empty hole rate. However, the probability of each seed suction hole on the seed metering disc 2 adsorbing multiple seeds increases, and the reseeding rate increases. At this time, rotate the adjusting handle 5 to adjust the position of the seed scraper roller 6 so as to scrape off excess seeds, ensuring one seed per hole, and reducing the reseeding rate.

[0033] When the seeds are discharged from the discharge port 9, the rubber roller 3 will close the seed dispensing disc 2, and the seed cleaning wheel 4 will clean up the broken seeds adsorbed by the seed dispensing disc 2, so as to facilitate the new round of sowing.

[0034] In summary, according to the air-blowing seed metering device of this utility model embodiment, the seed metering disc is driven by air pressure, the rubber roller can seal the seed metering disc to ensure the integrity of the device, the seed cleaning wheel can clean the seed metering disc to avoid clogging, and the position of the seed scraper roller can be adjusted by adjusting the handle to scrape off excess seeds and ensure planting effect.
