Technical Field

[0001] This invention relates to the field of wheat sowing technology, and more specifically, to a uniform sowing component based on a high-speed pneumatic wheat seeder. Background Technology

This device includes a rear connecting base and a front connecting base, with side baffles fixedly welded to both ends. Handles are fixedly connected to the outer walls of the side baffles. Several seed guiding chambers are installed between the side baffles. An air chamber module and a seeding control module are installed at the upper end of each seed guiding chamber. A fan module is connected to the air inlet of the air chamber module, and an electrically driven control integrated module is installed below the fan module.

This invention meets the different needs of seeders for different wheat seeding rates per acre, improving soil utilization.

[0003] The aforementioned patents still have shortcomings in practical use. Existing airflow seeders typically require wheat seeds to be mixed with insecticides before sowing. However, most of these devices currently only have a single sowing function, making it difficult to simultaneously achieve uniform mixing and precise dispersing of seeds and pesticides during airflow, thus affecting the efficacy of the pesticides and the quality of sowing.

[0004] Based on this, the present invention discloses a uniform seeding component based on a high-speed wheat air-feed seeder. Summary of the Invention

[0005] To address the problem that airflow seeders in the background typically require pre-mixing wheat seeds with insecticides before sowing, but their structures often only support a single sowing function, making it difficult to simultaneously achieve uniform mixing and precise dispersing of seeds and pesticides during airflow conveying, this invention provides a uniform sowing component based on a high-speed airflow wheat seeder. This component includes a mounting frame and a drive unit and a sowing unit mounted thereon. The mounting frame also houses a material storage box and a pesticide storage box. Several sowing components, driven by the drive unit, are located below the material distribution component on the mounting frame. Each sowing component includes a seed plow, and... A seeding pipe connected to the feed inlet; the driving unit includes a driving assembly, the driving assembly includes several sets of rolling wheels, the mounting frame is provided with support arms corresponding to each rolling wheel, the rolling wheels are connected to the mounting frame through the corresponding support arms, the mounting frame is provided with a driving rod, the driving rod is provided with a first gear corresponding to each rolling wheel, the rolling wheel and the first gear are connected by a belt, the mounting frame is also provided with a transmission rod, the end of the driving rod is also provided with a second gear, the end of the transmission rod is provided with a third gear, the second gear and the third gear are connected by a belt; Secondly, the sowing assembly includes a sowing box mounted on a mounting frame, the sowing box being rotatably connected to a transmission rod, a sowing disc being provided inside the sowing box, the sowing disc being fixedly connected to the transmission rod, a discharge trough being provided inside the sowing box, a sowing tube being provided inside the discharge trough, one end of the sowing tube being connected to the discharge trough, and the other end of the sowing tube being mounted on a sowing plow, the sowing plow being fixed on the mounting frame. It should be added that the seeding tray includes a rotating disk fixedly connected to the transmission rod, and the outer edge of the rotating disk is evenly provided with a plurality of receiving grooves, and the outer edge of the receiving grooves is provided with scrapers; moreover, the front of the discharge trough is provided with a notch adapted to the rotating disk, and the end of the seeding tube located in the discharge trough is adapted to the opening direction of the receiving groove.

[0006] Based on this, as a further improvement to this technical solution, the sowing section includes a blower mounted on a mounting frame, with the output end of the blower connected to a material distribution component. The material distribution component includes an air duct connected to the blower, which is connected to a medicine storage tank and a material storage tank along the airflow direction. Specifically, a suction pipe is provided at the bottom of the material storage tank, and the blower is connected to the material storage tank via the suction pipe. Similarly, a medicine suction pipe is provided at the bottom of the medicine storage tank, and the blower is connected to the medicine storage tank via the suction pipe. Furthermore, the inner diameter of the blower is much larger than the inner diameter of the ends of the suction pipe and the suction pipe connected to the blower.

[0007] Secondly, a mixing pipe is installed at the end of the blower pipe, and a spiral guide rail is installed inside the mixing pipe. A distribution pipe is also installed below the blower pipe, and a distribution plate is installed inside the distribution pipe. The distribution pipe is divided into several uniform distribution ports by the distribution plate, and the distribution ports are connected to the seeding components respectively. In addition, the mixing pipe has a conical structure, and the end of the mixing pipe is provided with several vent holes with a diameter smaller than that of wheat, and the end of the spiral guide rail points to the dispensing pipe. In addition, the material distribution plate has a cross-shaped structure, and the bottom of the material distribution plate is flush with the bottom of the material distribution tube, and the height of the material distribution plate is less than the height of the material distribution tube; moreover, the bottom of the material distribution tube is provided with a mounting shell, and the mounting shell is provided with a discharge tube corresponding to the material distribution port. One end of the discharge tube is connected to the corresponding material distribution port, and the other end of the discharge tube is connected to the seeding box.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This uniform seeding component on a high-speed pneumatic wheat seeder utilizes a combination of a blower and a distribution component. The high-speed airflow generated by the blower creates a low-pressure zone in the main pipeline, simultaneously drawing in seeds and insecticide from the storage bins and pesticide bins using Bernoulli's principle. Since the suction port is located upstream of the pesticide suction port, the seeds first enter the airflow channel before merging with the pesticide. In the subsequent mixing pipe, a spiral guide rail guides the seeds to create a rotating flow, ensuring dynamic, continuous, and thorough mixing during transport. This method eliminates the cumbersome manual pre-mixing process required before traditional seeding, improving operational efficiency and significantly enhancing the uniformity and stability of pesticide adhesion. This achieves synchronous mixing and precise proportioning of seeds and pesticide during pneumatic transport.

[0009] 2. In this uniform seeding component of a high-speed air-driven wheat seeder, a cross-shaped distribution plate with a height lower than the pipe wall is installed inside the distribution pipe. Combined with the stable material flow formed after upstream mixing, the seeds fill the upper space after entering the distribution pipe and are then evenly distributed to each distribution port. At the same time, each distribution port corresponds to an independent discharge channel, accurately guiding the mixed material into its respective seeding unit. This structural design effectively overcomes the problem of seeding fluctuation caused by uneven material distribution in air-driven seeding, ensuring the consistency and reliability of multi-row seeding, and facilitating the maintenance of stable seeding density and row spacing accuracy under high-speed operating conditions. 3. In this uniform seeding component of a high-speed air-driven wheat seeder, through the linkage transmission mechanism between the drive unit and the seeding component, the rolling wheel passively rotates with the movement of the whole machine. The power is transmitted sequentially to the transmission rod and each seeding disc through the gear and belt system. The outer edge of the seeding disc is equipped with a quantitative receiving groove and a scraper, which automatically completes the picking up, metering and releasing of seeds during rotation, and achieves fixed-point seeding in conjunction with the fixed seeding plow. This mechanical quantitative seeding structure requires no additional power source, responds quickly, and seeds stably. It also seamlessly integrates with the front-end airflow mixing system, thus ensuring precise control of the seeding amount per hole even when the machine is running at high speed, thereby improving the uniformity of seedling emergence and crop growth in the field.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Existing airflow seeders typically require wheat seeds to be mixed with insecticides before sowing, but their structure usually only supports a single sowing function, making it difficult to achieve uniform mixing and precise sowing of seeds and pesticides simultaneously during airflow.

[0014] Therefore, this invention provides a uniform seeding component based on a high-speed pneumatic wheat seeder, see [link to relevant documentation]. Figure 1 , Figures 5-6As shown, it includes a mounting frame 1 and a drive unit and a sowing unit disposed thereon. The mounting frame 1 is also provided with a storage box 4 and a medicine storage box 5. Several sowing components 7 driven by the drive unit are disposed below the material distribution component 6 on the mounting frame 1. The sowing component 7 includes a sowing plow 75 and a sowing tube 74 communicating with the material distribution port 610. The drive unit includes a drive component 2, which includes several sets of rolling wheels 21. The mounting frame 1 is provided with support arms 22 corresponding to each rolling wheel 21. The rolling wheels 21 are connected to the mounting frame 1 through the corresponding support arms 22. The mounting frame 1 is provided with a drive rod 24. The drive rod 24 is provided with a first gear 23 corresponding to each rolling wheel 21. The rolling wheels 21 and the first gear 23 are connected by a belt. The mounting frame 1 is also provided with a transmission rod 27. A second gear 25 is provided at the end of the drive rod 24. A third gear 26 is provided at the end of the transmission rod 27. The second gear 25 and the third gear 26 are connected by a belt. Secondly, the sowing assembly 7 includes a sowing box 71 mounted on the mounting frame 1. The sowing box 71 is rotatably connected to the transmission rod 27. A sowing disc 72 is provided inside the sowing box 71. The sowing disc 72 is fixedly connected to the transmission rod 27. A discharge trough 73 is provided inside the sowing box 71. A sowing tube 74 is provided inside the discharge trough 73. One end of the sowing tube 74 is connected to the discharge trough 73. The other end of the sowing tube 74 is mounted on the sowing plow 75. The sowing plow 75 is fixed on the mounting frame 1. It should be added that the seeding tray 72 includes a rotating disk 721 fixedly connected to the transmission rod 27. The outer edge of the rotating disk 721 is evenly provided with a plurality of receiving grooves 722, and the outer edge of the receiving grooves 722 is provided with scrapers 723. Moreover, the front width of the discharge trough 73 is provided with a notch that matches the rotating disk 721, and the end of the seeding tube 74 located in the discharge trough 73 matches the opening direction of the receiving grooves 722.

[0015] During operation, after the entire mounting frame 1 is placed on the sowing ground, it is suspended from a tractor or a corresponding trailer. As the roller 21 rolls on the ground, the first gear 23 rotates via a belt, which in turn drives the drive rod 24. The drive rod 24, after being rotated, then drives the transmission rod 27 through the transmission between the second gear 25 and the third gear 26. The rotation of the transmission rod 27 then drives the rotating discs 721 inside several sowing boxes 71 to rotate. After the wheat seeds are evenly fed into the sowing boxes 71, the rotating discs 721 continuously rotate, causing the seeds to spin. The turntable 721 has several uniformly sized receiving grooves 722 on its outer edge, and the receiving grooves 722 are equipped with scrapers 723 for scooping seeds on their outer edge. Therefore, when the turntable 721 rotates, the scrapers 723 scoop the seeds into the receiving grooves 722. Then, when the receiving grooves 722 rotate into the discharge grooves 73, due to gravity and when the angle of the receiving grooves 722 is tilted, the seeds in the receiving grooves 722 will fall into the discharge grooves 73 and slide directly into the sowing tubes 74. Then, the seeds are directly and evenly sprinkled into the seed pits opened by the sowing plow 75 through the sowing tubes 74.

[0016] For details, see Figures 1-4 As shown, the sowing section includes a blower 3 mounted on the mounting frame 1, and the output end of the blower 3 is connected to a material distribution component 6. The material distribution component 6 includes an air pipe 61 connected to the blower 3. The air pipe 61 is connected to the medicine storage box 5 and the material storage box 4 along the airflow direction. Specifically, the bottom of the material storage box 4 is provided with a suction pipe 62, and the blower 61 is connected to the material storage box 4 through the suction pipe 62. The bottom of the medicine storage box 5 is provided with a suction pipe 63, and the blower 61 is connected to the medicine storage box 5 through the suction pipe 63. Moreover, the inner diameter of the blower 61 is much larger than the inner diameter of the suction pipe 63 and the end of the suction pipe 62 connected to the blower 61.

[0017] Secondly, a mixing pipe 64 is provided at the end of the blower pipe 61. A spiral guide rail 65 is provided inside the mixing pipe 64. A distribution pipe 66 is also provided at the bottom of the blower pipe 61. A distribution plate 67 is provided inside the distribution pipe 66. The distribution pipe 66 is divided into several uniform distribution ports 610 by the distribution plate 67. The distribution ports 610 are connected to the seeding components 7 respectively. In addition, the mixing pipe 64 has a conical structure, and the end of the mixing pipe 64 is provided with several exhaust holes with a diameter smaller than that of wheat. The end of the spiral guide rail 65 points to the distribution pipe 66 in the spiral guiding direction. In addition, the material distribution plate 67 has a cross-shaped structure, and the bottom of the material distribution plate 67 is flush with the bottom of the material distribution pipe 66, and the height of the material distribution plate 67 is less than the height of the material distribution pipe 66; moreover, the bottom of the material distribution pipe 66 is provided with a mounting shell 68, and the mounting shell 68 is provided with a discharge pipe 69 corresponding to the material distribution port 610. One end of the discharge pipe 69 is connected to the corresponding material distribution port 610, and the other end of the discharge pipe 69 is connected to the seeding box 71.

[0018] When working, blower 3 starts blowing air. When the strong air blows into the blower pipe 61, according to Bernoulli's principle, when the blower pipe 61 is flowing with high-speed airflow, the static pressure is small. Therefore, a suction-like effect will be generated in the suction pipe 63 and the suction pipe 62. The seeds in the storage box 4 are drawn into the blower pipe 61 through the suction pipe 62 and the relevant drugs in the storage box 5 are drawn into the blower pipe 61 through the suction pipe 63 for mixing. Furthermore, it should be noted that, through Figure 3 As can be seen, the suction pipe 62 is located at the front end of the gas flow direction of the drug suction pipe 63. Therefore, when the seeds flow in the blower pipe 61, they will pass through the drug suction pipe 63 and enter the branch of the blower pipe 61. In this way, the seeds will continue to move forward with the drug and will be pre-mixed during the process. Then they will enter the mixing pipe 64. Since the mixing pipe 64 is equipped with a spiral guide rail 65, the spiral guide rail 65 will guide the seeds to move forward in a spiral shape in the mixing pipe 64, that is, to generate a rotational stirring effect, so that the seeds and the drug are fully mixed. Then they leave the mixing pipe 64. Under the action of gravity and the guidance of the spiral guide rail 65, the seeds will flow out through the distribution pipe 66. Since the distribution pipe 66 is smaller than the blower pipe 61, and given the high-speed airflow within the blower pipe 61, the distribution plate 67 is designed to be smaller than the distribution pipe 66. This design allows the top of the distribution pipe 66 to be filled with seeds first, before reaching the distribution plate 67. As the seeds fill the distribution pipe 66, and are then divided by the distribution plate 67, it ensures that the seeds within the distribution plate 67 are evenly distributed. Therefore, the seeds flowing out of the distribution plate 67 are evenly distributed into their respective seeding boxes 71 through several distribution ports 610. Afterward, they are fed into the seeding plow 75 for sowing via the seeding tray 72. It should be noted that the design of the seeding box 71 takes into account the insertion position of the feed pipe 69 to ensure that the seeds do not scatter when they are blown into the seeding box 71.

[0019] In summary, this effectively solves the problem that existing airflow seeders usually require wheat seeds to be mixed with insecticides before sowing, but their structure mostly only supports a single sowing function, making it difficult to achieve uniform mixing and precise sowing of seeds and agents simultaneously during airflow.
