Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a visual seeder. Background Technology

[0002] With the rapid development of precision agriculture and intelligent agricultural machinery, agricultural production has placed higher demands on sowing equipment, especially in terms of sowing accuracy, operational transparency, and ease of operation. Traditional seeders mostly rely on mechanical structures to control the seed distribution process, lacking real-time monitoring of their internal operating status. This makes it difficult to detect abnormalities such as missed sowing, seed jamming, and uneven seed distribution in a timely manner, affecting sowing quality and germination rate. A search revealed a visual seeder and a seeder containing the same device, disclosed in existing technology announcement number CN220511637U. This device has a video probe on its casing. During the seed adsorption process at the air suction hole, the video probe transmits images to the driver's cab in real time, allowing the sowing personnel to monitor the seed adsorption status and avoid missed or over-sowing, thus improving sowing quality. However, during use, the camera is not completely inside the seeder, making it susceptible to external light brightness during image acquisition, leading to abnormal image exposure and affecting the sowing personnel's ability to monitor seed adsorption.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0014] Beneficial effects:

[0015] 1. By having the first and second acquisition units of the image acquisition component penetrate deep into the first and second sowing chambers respectively, real-time image information inside the sowing chambers can be directly acquired. This effectively avoids interference from external ambient light, significantly improving the clarity and stability of image acquisition. This ensures that operators can accurately and reliably monitor the seeding process (such as seed suction and holding status) and promptly detect abnormalities such as missed sowing or seed jamming. At the same time, the first and second sowing units are horizontally spaced, working in conjunction with the independent first and second acquisition units to achieve independent and synchronous visual monitoring of the double-row sowing operation, improving the overall transparency and monitoring efficiency of the operation.

[0016] 2. The first and second partition plates physically divide the seeding chambers into functionally distinct first seed suction area, second seed suction area, first seed scraping area, and second seed scraping area. This effectively prevents the seeds to be suctioned from mixing and interfering with the seeds to be discharged, and optimizes the flow path and management of the seeds within the chamber. The design of the first and second through channels precisely aligns with the movement trajectory of the first and second seed suction holes, ensuring that the suctioned seeds can be smoothly transferred from the suction area to the scraping area, creating conditions for subsequent seed scraping and discharging, and improving the smoothness and reliability of the seed discharging process.

[0017] 3. Through the elastic force of the first and second scrapers, the first and second scrapers can adaptively move along the first and second slide grooves, always maintaining elastic contact with the first and second seed suction disc bodies. This design can automatically compensate for the working gap between the scraper and the seed suction disc body (e.g., caused by manufacturing tolerances or wear), ensuring that the scraper can effectively and reliably scrape the seeds on the suction hole to the first or second seed outlet under any working condition, preventing missed scraping or incomplete scraping, and improving the accuracy and consistency of seed dispensing. The slide groove structure ensures the straightness and stability of the scraper movement. Attached Figure Description

[0026] By adopting the above technical solution, the first and second acquisition parts of the image acquisition component 3 are respectively inserted into the first and second sowing chambers, enabling direct acquisition of real-time image information inside the sowing chambers. This effectively avoids interference from external ambient light, significantly improving the clarity and stability of image acquisition, thereby ensuring that operators can accurately and reliably monitor the seeding process (such as seed suction and holding status) and promptly detect abnormalities such as missed sowing and seed jamming. At the same time, the first and second sowing parts are horizontally spaced, working in conjunction with the independent first and second acquisition parts to achieve independent and synchronous visual monitoring of the double-row sowing operation, improving the overall transparency and monitoring efficiency of the operation.

[0028] By adopting the above technical solution, the first and second mounting components provide an independent and stable installation environment for the first camera 4 and the second camera 5, ensuring that the core components of the camera are located inside the seeding chamber, maximizing the isolation of the influence of external stray light, and guaranteeing the image acquisition quality. The first camera 4 and the second camera 5 are precisely aligned with their respective first and second seeding chambers, achieving accurate and high-definition imaging of the working status inside the two independent seeding chambers (especially the seed adsorption status at the seed suction hole). The horizontal spacing of the first camera 4 and the second camera 5 matches the position of their corresponding seeding chambers, ensuring the synchronization and independence of the dual-row monitoring.

[0029] Furthermore, both the first camera 4 and the second camera 5 have supplementary lighting capabilities, meaning they can acquire image information even in enclosed spaces.

[0033] By adopting the above technical solution, the second mounting cylinder 9 provides a guide channel for the axial insertion of the second camera 5, facilitating installation and positioning. The cooperation of the two second limiting grooves with the second limiting plate 11 effectively restricts the radial freedom of the second camera 5, preventing rotation or displacement and ensuring that the viewing angle of the second camera 5 is always precisely aligned with the inside of the second seeding chamber. By screwing the second fastener (such as a bolt) into the second threaded hole and abutting against the second limiting plate 11, the second camera 5 can be quickly and reliably fixed and disassembled axially within the second mounting cylinder 9, simplifying the installation, debugging, and maintenance process of the camera and ensuring structural stability. This structural design corresponds to the first mounting component, ensuring the independence and reliability of the second camera 5's installation.

[0036] Please refer to Figure 3 The sowing assembly 2 further includes: a first partition plate 18, which extends radially along the first sowing chamber and divides the first sowing chamber into a first seed-collecting area 19 and a first seed-scraping area 20; a first seed-inlet chamber communicating with the first seed-collecting area 19 to allow seeds from the first seed-inlet chamber to enter the first seed-collecting area 19; a first seed-scraping assembly 14 located in the first seed-scraping area 20; and a first through groove 21 provided on the first partition plate 18, the position of which corresponds to the position of the first seed-collecting hole, the first through groove 21 being used to allow seeds collected by the first seed-collecting disc assembly 13 to pass through the first seed-collecting hole. A seed-collecting area 19 moves to a first seed-scraping area 20; a second partition plate extends radially along the second sowing chamber, dividing the second sowing chamber into a second seed-collecting area and a second seed-scraping area; a second seed inlet chamber communicates with the second seed-collecting area to allow seeds from the second seed inlet chamber to enter the second seed-collecting area; a second seed-scraping assembly is located in the second seed-scraping area; a second through groove is provided on the second partition plate, the position of the second through groove corresponding to the position of the second seed-collecting hole, the second through groove being used to move the seeds adsorbed by the second seed-collecting plate assembly from the second seed-collecting area to the second seed-scraping area.

[0037] By adopting the above technical solution, the first partition plate 18 and the second partition plate physically divide their respective sowing chambers into a first seed-suction area 19, a second seed-suction area, a first seed-scraping area 20, and a second seed-scraping area, which have clearly defined functions. This effectively prevents the seeds to be suctioned from mixing and interfering with the seeds to be discharged, and optimizes the flow path and management of the seeds in the chamber. The design of the first through groove 21 and the second through groove is precisely aligned with the movement trajectory of the first seed suction hole and the second seed suction hole, ensuring that the suctioned seeds can be smoothly transferred from the suction area to the scraping area, creating conditions for subsequent seed scraping and discharging, and improving the smoothness and reliability of the seed discharging process.

[0038] Please refer to Figure 3 The first seed suction plate assembly 13 includes: a first scraper 22, which extends along a first arc-shaped trajectory and is used to scrape the seeds adsorbed on the first seed suction plate body to the first seed outlet; a first base 23, which is mounted on the first outer shell 12 and located in the first seed scraping area 20, and has a first groove extending toward the first outer shell 12; the first scraper 22 is movably disposed in the first groove along the extension direction of the first groove; and a first spring, which is located in the first groove, with its two ends connected to the first base 23 and the first scraper 22, respectively; the first spring is used for... The first scraper 22 abuts against the body of the first seed suction plate; the second scraper extends along a second arc-shaped trajectory and is used to scrape the seeds adsorbed on the body of the second seed suction plate to the second seed outlet; the second base is mounted on the second outer shell 15 and located in the second seed scraping area, and the second base has a second sliding groove extending toward the second outer shell 15; the second scraper is movably disposed in the second sliding groove along the extension direction of the second sliding groove; the second spring is located in the second sliding groove, and the two ends of the second spring are respectively connected to the second base and the second scraper; the second spring is used to make the second scraper abut against the body of the second seed suction plate.

[0039] By adopting the above technical solution, the first scraper 22 and the second scraper can adaptively move along the first and second slide grooves through the elastic force of the first and second springs, always maintaining elastic contact with the first and second seed suction disc bodies. This design can automatically compensate for the working gap between the scraper and the seed suction disc body (e.g., caused by manufacturing tolerances or wear), ensuring that the scraper can effectively and reliably scrape the seeds on the seed suction hole to the first or second seed outlet under any working condition, preventing missed scraping or incomplete scraping, and improving the accuracy and consistency of seed dispensing. The slide groove structure ensures the straightness and stability of the scraper movement.

[0040] Specifically, through the preset arc design of the first scraper 22 and the second scraper, the seeds can be prevented from swinging back and forth during the scraping process, ensuring consistent seed placement.

[0041] Specifically, the first scraper 22 and the second scraper are made of copper.

[0042] By adopting the above technical solution, copper is selected to manufacture the first scraper 22 and the second scraper. The good wear resistance and moderate hardness of copper effectively reduce the wear rate of the scraper during long-term seed scraping operations and extend the service life of the scraper. At the same time, copper has a certain degree of self-lubrication and good thermal conductivity, which helps to reduce the frictional resistance and heat accumulation between the scraper and the seed suction plate body (usually metal or engineering plastic), reduce working noise, and reduce the possibility of seeds adsorbed due to frictional static electricity, further ensuring the smoothness and reliability of the seed scraping action.

[0043] Please refer to Figure 1 The first seed suction plate assembly 13 further includes: a first suction cup housing 24, the first seed suction plate body being rotatably disposed relative to the first suction cup housing 24, and the first suction cup housing 24 being connected to the first housing 12; the second seed suction plate assembly further includes: a second suction cup housing, the second seed suction plate body being rotatably disposed relative to the second suction cup housing, and the second suction cup housing being connected to the second housing 15; an air pump, the input end of which is connected to the first negative pressure chamber and the second negative pressure chamber respectively; the air pump is mounted on an installation reference; the air pump is used to create a negative pressure space in the first negative pressure chamber and the second negative pressure chamber; wherein, the first housing 12, the first seed suction plate assembly 13, and the first seed scraping assembly 14 form a first sowing section; the second housing 15, the second seed suction plate assembly, and the second seed scraping assembly form a second sowing section.

[0044] By adopting the above technical solution, the first suction cup shell 24 and the second suction cup shell provide a stable and sealed rotating support structure (forming the first negative pressure chamber and the second negative pressure chamber) for the first seed suction plate body and the second seed suction plate body, respectively. This is a key basic component for realizing the negative pressure adsorption function. The air pump, as a negative pressure source, is connected to the first negative pressure chamber and the second negative pressure chamber through its output end, providing a stable and consistent negative pressure environment for the two independent sowing sections, ensuring that the first seed suction plate assembly 13 and the second seed suction plate assembly can perform precise adsorption and seed collection operations synchronously and reliably. This integrated air supply design simplifies the system structure and improves efficiency. The first sowing section and the second sowing section each contain a complete shell, a seed suction plate assembly, and a seed scraping assembly, realizing a truly independent dual-row sowing functional unit.

[0045] Working principle:

[0046] First, the seeds are poured into the seeding space of the seeding assembly 2, so that the seeds flow into the first seeding chamber of the first outer shell 12 and the second seeding chamber of the second outer shell 15;

[0047] The seeds enter the first seed-inlet chamber and are separated into the first seed-absorbing area 19 by the first partition plate 18;

[0048] The seeds enter the second seed-absorbing area separated by the second partition plate from the second seed-inlet chamber;

[0049] When the air pump is started, a negative pressure is formed in the first negative pressure chamber of the first seed suction plate assembly 13 and the second negative pressure chamber of the second seed suction plate assembly; this negative pressure environment is transmitted to the first sowing chamber and the second sowing chamber.

[0050] The seeds located in the first seed absorption area 19 are adsorbed onto multiple first seed absorption holes of the rotating first seed absorption disc body under negative pressure.

[0051] The seeds located in the second seed-absorbing area are adsorbed onto multiple second seed-absorbing holes of the rotating second seed-absorbing disc body under negative pressure;

[0052] The first seed suction disc body with seeds adsorbed continues to rotate, carrying the seeds through the first through groove 21 on the first partition plate 18, and from the first seed waiting area 19 into the first seed scraping area 20.

[0053] The second seed-absorbing disc body, which has adsorbed seeds, continues to rotate, carrying the seeds through the second groove on the second partition plate, and from the second seed-to-absorption area into the second seed-scraping area.

[0054] During the seed transfer process, the first camera 4 located inside the first seeding chamber collects real-time images of the seed adsorption status on the first seed suction plate body (such as whether it is adsorbed, whether the adsorption is stable, whether there is excessive or insufficient adsorption) and the internal images of key areas such as the seeds passing through the first through groove 21.

[0055] Meanwhile, the second camera 5 located inside the second seeding chamber collects real-time images of the seed adsorption status on the second seed suction plate body and the seeds passing through key areas such as the second through groove.

[0056] Since the core parts of the first camera 4 and the second camera 5 are both inserted deep into their respective seeding chambers, interference from external ambient light is effectively avoided, ensuring the clarity and stability of the acquired images.

[0057] When the seeds adsorbed on the first seed suction plate body rotate and reach the first seed outlet position located in the first seed scraping area 20, the first scraper 22 of the first seed scraping assembly 14 always maintains elastic contact with the first seed suction plate body under the elastic force of the first spring.

[0058] The first scraper 22 reliably scrapes the seeds adsorbed on the first seed suction hole and discharges them through the first seed outlet, completing the sowing of the first row;

[0059] When the seeds adsorbed on the second seed suction disc body rotate and reach the second seed outlet position located in the second seed scraping area, the second scraper of the second seed scraping assembly always maintains elastic contact with the second seed suction disc body under the elastic force of the second spring.

[0060] The second scraper reliably scrapes the seeds adsorbed on the second seed suction hole and discharges them through the second seed outlet, completing the sowing of the second row;

[0061] The real-time image signals inside the seeding chamber collected by the first camera 4 and the second camera 5 are transmitted to the display equipment in the cab or control center. By observing these clear internal images, operators can intuitively monitor the entire process of seed suction, holding, transfer and dispensing in the first and second rows, and promptly detect and handle abnormal situations such as missed seeding, over-seeding, and seed jamming.

[0062] The above process is carried out cyclically under the continuous rotation of the first seed suction disc and the second seed suction disc, realizing continuous, precise and visualized seeding operations in two rows.
