Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and in particular to a seeder and a seeding method. Background Technology

[0002] For vegetable cultivation in clay soil, existing technologies mainly employ direct seeding and transplanting. The drawbacks of these technologies are that clay soil is uneven in texture and prone to clumping, leading to inconsistent sowing depths and a seedling survival rate of only 70-85% with direct seeding. Transplanting requires additional costs for seedling trays and potting soil, and the root damage rate can reach 40%. Traditional seeders require separate steps for soil breaking and furrowing, resulting in low efficiency, reliance on manual labor, significant pollution from fuel-powered machines, limited range of ordinary electric vehicles, and a disconnect between irrigation and sowing, necessitating separate irrigation equipment and low resource utilization. Summary of the Invention

It is highly efficient, with irrigation and sowing occurring simultaneously. Furthermore, the seedlings are covered with substrate soil, which improves seed germination and seedling survival rates. It also eliminates the costs associated with seed trays and nutrient soil.

[0039] Reference Figure 1 , Figure 2 and Figure 4 According to an embodiment of the present invention, a seeder includes a body 100, a hydrogen-powered power unit 200, a soil-crushing device 500, a ditching device 600, a synchronous soil-covering, sowing, and drip irrigation device 700, a compaction device 800, and a control system. The hydrogen-powered power unit 200 is connected to the body 100 and is used to drive the body 100 to move. The soil-crushing device 500 is connected to the body 100. The ditching device 600 is connected to the body 100 and is located behind the soil-crushing device 500. The synchronous soil-covering, sowing, and drip irrigation device 700 is connected to the body 100 and is connected to the hydrogen-powered power unit 200. The synchronous soil-covering, sowing, and drip irrigation device 700 is located behind or inside the ditching device 600. The compaction device 800 is connected to the body 100 and is located behind the synchronous soil-covering, sowing, and drip irrigation device 700. The control system is connected to the hydrogen-powered power unit 200 and the body 100.

[0040] The machine body 100 specifically includes a frame 110, a housing 120, and wheels 130. The housing 120 is connected to the frame 110, and the wheels 130 are connected to the underside of the frame 110. The frame 110 is the main component of the machine body 100, mainly used to support and fix the installation of other components. The housing 120 is used to enclose the machine body 100 and isolate other components from the outside world. The wheels 130 are rotatably connected to the frame 110 and can roll on the ground, thereby driving the machine body 100 to move. It should be understood that the machine body 100 is generally also equipped with a steering component (refer to the vehicle steering component in the prior art). The steering component is connected to the wheels 130 and the frame 110, assisting the wheels 130 in steering. Moreover, the control system (control element) can be connected to the steering component, thereby intelligently controlling the steering of the seeder, which is conducive to the intelligent and automatic operation of the seeder. Furthermore, the machine body 100 also includes tracks 140, which are connected to the outer circumference of the wheels 130, thereby enabling the seeder to move more smoothly on agricultural land and preventing the wheels 130 from sinking into soft soil. It should be understood that, unless otherwise specified, the front and rear directions in this invention refer to the position of the front of the machine body 100 as "front" and the rear as "rear." The direction from the front to the rear of the machine body 100 is the front-to-back direction. The direction in which the seeder and machine body 100 sow seeds is generally forward (without turning). Therefore, the various devices arranged from front to back will sequentially pass through the same area, allowing for sequential soil breaking, furrowing, covering, sowing, drip irrigation, and compaction. The up-down direction is the conventional up-and-down direction, or the direction of gravity is vertically downward. The left-right direction is perpendicular to both the front-to-back and up-and-down directions. It should be understood that device A is located behind (in front of, inside of, etc.) device B, and device A may be wholly or partially located behind (in front of, inside of, etc.) device B. The same applies to other similar descriptions in this invention.

[0041] The hydrogen energy power unit 200 (fuel cell, hydrogen fuel cell) specifically involves the reaction of hydrogen and oxygen in a proton exchange membrane fuel cell (PEMFC) reactor. The resulting pure water is condensed, purified, and then delivered via a synchronous soil covering and seeding drip irrigation device 700 for simultaneous sowing and irrigation. The fuel cell has an energy conversion efficiency of 60-80%, zero carbon emissions, and completes a double closed-loop resource utilization process: "hydrogen energy → electrical energy → mechanical energy" and "reacting water → irrigation water." The hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis. Hydrogen and oxygen are supplied to the anode and cathode, respectively. Hydrogen diffuses outward through the anode and reacts with the electrolyte, releasing electrons that travel through an external load to the cathode. In this process, hydrogen and oxygen react to produce water, generating electricity as a byproduct. Its characteristics include no pollution, no noise, and high efficiency.

[0042] The soil-breaking device 500 is used to break up and loosen the soil clods in the field beforehand, reducing the resistance of the subsequent furrowing device 600. The furrowing device 600 separates the broken soil to both sides, creating a furrow of a certain depth to facilitate subsequent seed sowing. It is important to understand that since the furrowing device 600 is fixed to the frame 110 of the machine body 100, it will not move arbitrarily. Therefore, the depth and width of the furrow it creates will remain essentially constant, enabling precise sowing and ensuring that the sowing depth is basically uniform. This is beneficial for improving seed germination rate and seedling survival rate; in particular, it can solve the problem of inconsistent sowing depth caused by the uneven texture and tendency of clay soil to clump together, which is common in traditional methods.

[0043] The synchronous soil covering and sowing drip irrigation device 700 can simultaneously sow seeds, drip irrigate, and continue soil covering after soil covering (i.e. covering with substrate soil), thus synchronizing irrigation and sowing. Furthermore, the substrate soil is pre-covered at the bottom of the field furrows, and the seeds are sown on the substrate soil and then covered with substrate soil, which can improve the seed germination rate and seedling rate, and also save the cost of seed trays, nutrient soil, etc. Substrate soil, also known as base soil or soilless cultivation medium, is a synthetic soil material. It possesses excellent aeration and water retention, providing a favorable growing environment for plants. Its loose structure and high porosity facilitate air circulation and root respiration. Simultaneously, the inorganic substances in substrate soil have good water retention, ensuring plants receive sufficient moisture during growth. Substrate soil can replace traditional soil, providing a more stable and cleaner growing environment. Furthermore, its excellent aeration and water retention reduce the occurrence of pests and diseases, improving plant survival rates. Particularly for clay soils, substrate soil can improve aeration and drainage, reducing secondary salinization.

[0044] The 800 compaction device can compact the soil to a certain extent to ensure that the seeds, substrate soil and the original field soil are in close contact and stabilize the topsoil.

[0045] The control system, connected to the hydrogen energy power unit 200 and the machine body 100, can intelligently control the seeder to operate automatically, saving manpower and making sowing more precise and stable. It's important to understand that the control system typically contains intelligent control components, such as chips, microprocessors, CPUs, and microcontrollers. It can control the operation of the hydrogen energy power unit 200 and the machine body 100 through intelligent control programs. Furthermore, the control system can also connect to other devices, such as a synchronous soil covering, sowing, and drip irrigation device 700, thereby enabling more precise and stable control of sowing, soil covering, and drip irrigation.

[0046] Therefore, the seeder of this invention is equipped with a soil-crushing device 500, a ditching device 600, a synchronous soil-covering, sowing, and drip irrigation device 700, and a compaction device 800, which can complete soil crushing, ditching, soil covering, sowing, drip irrigation, and compaction in one go, resulting in high efficiency. Irrigation and sowing are synchronized, and the seedlings are covered with substrate soil, which improves the seed germination rate and seedling survival rate, and also saves the cost of seed trays and nutrient soil. It is equipped with a hydrogen energy power unit 200, which uses hydrogen energy. Hydrogen energy has zero carbon emissions, and the reaction water can be recycled and purified for drip irrigation, which meets the requirements of green and sustainable development. The control system is connected to the hydrogen energy power unit 200 and the machine body 100, which can intelligently control the seeder to operate automatically and sow, saving manpower and making sowing more precise and stable.

[0047] Reference Figure 1 and Figure 7 In some embodiments of the present invention, the hydrogen energy power unit 200 includes a liquid hydrogen storage tank 210, a fuel reactor 220, a battery 230 and an electric motor. The liquid hydrogen storage tank 210 and the fuel reactor 220 are connected, the fuel reactor 220 and the battery 230 are connected, the battery 230 and the electric motor are electrically connected, the electric motor is driven to the body 100, and the fuel reactor 220 and the synchronous soil covering, seeding and drip irrigation device 700 are connected.

[0048] The liquid hydrogen storage tank 210 is used to store liquid hydrogen. Hydrogen and oxygen (the hydrogen energy power unit 200 may also include an oxygen storage cylinder connected to the fuel reactor 220; or it may extract or directly use external air to react with hydrogen) enter the fuel reactor 220. The generated electrical energy is input into the battery 230 to power components such as the electric motor (fan 710). The water produced after the reaction can be treated by the synchronous soil covering and seeding drip irrigation device 700 and then delivered to the seeds in the field for drip irrigation. Specifically, the fuel reactor 220 can be the reactor of a proton exchange membrane fuel cell (PEMFC).

[0049] It should be understood that the synchronous soil covering and seeding drip irrigation device 700 may include a drain pipe 430, a cooling component 410 and a filter component 420. One end of the cooling component 410 is connected to the fuel reactor 220, thereby condensing and cooling the water generated by the fuel reactor 220, and some gaseous impurities can be directly separated and removed. The other end of the cooling component 410 is connected to one end of the filter component 420, thereby filtering out other impurities in the water and preventing impurities from contaminating the soil and seeds. The other end of the filter component 420 is connected to one end of the drain pipe 430, and the other end of the drain pipe 430 is generally connected to the mixing discharge component 760 (first channel 761). The cooling assembly 410 may further include a cooling pipe 411, one end of which is connected to the fuel reactor 220, and the other end of which is connected to one end of the filter assembly 420. A portion of the cooling pipe 411 (or, in other words, the cooling pipe 411 is provided with an air-cooled pipe section 411a) may be positioned in front of the fan 710 (in front of the seeder; behind the direction of the fan 710's airflow), thereby utilizing the airflow brought by the fan 710 to assist in heat dissipation. Moreover, the air blown out by the fan 710 can carry a portion of heat (by reasonably setting the distance between the air-cooled pipe section 411a and the fan 710, the amount of heat and the temperature at which the seeds are heated can be controlled), thereby heating the seeds to a certain extent, assisting in seed germination and growth, and improving the seed germination rate and seedling rate. Another part of the cooling pipe 411 (or, the cooling pipe 411 with a substrate soil heat exchange section 411b) can be fitted with a substrate soil storage component 740 (a soil storage cylinder; generally passing through the bottom, and the substrate soil storage component 740 has a substrate soil delivery outlet at the bottom, so that the delivered substrate soil can be heated). This allows for both heat exchange and cooling with the substrate soil, while also appropriately heating the substrate soil (soil has poor heat exchange capacity, and short-term contact will not cause the substrate soil to heat up excessively), thereby assisting seed germination and growth, and improving seed germination rate and seedling rate. Furthermore, other sections of the cooling pipe 411 (non-air-cooled section 411a, non-substrate soil heat exchange section 411b) can continue to use other cooling methods, such as dedicated cooling fans, semiconductor cooling chips, etc. The filter component 420 can specifically include graphene composite filter elements, HEPA filters, activated carbon, and other filter components.

[0050] The synchronous soil covering and seeding drip irrigation device 700 may also include a pump. The pump's inlet is connected to the fuel reactor 220, and the pump's outlet is connected to the drain pipe 430 (or other components, such as the cooling assembly 410, cooling pipe 411, filter assembly 420, etc.). The pump transports the water vapor generated by the fuel reactor 220. In some embodiments, the synchronous soil covering and seeding drip irrigation device 700 may not include a pump. The fuel reactor 220 continuously generates water vapor, which accumulates at one end of the drain pipe 430 (or other pipeline components). Because the water vapor carries a certain amount of heat and has a high temperature, it expands in volume, resulting in a higher pressure at one end of the drain pipe 430. Therefore, the water vapor naturally flows towards the lower pressure section of the pipeline. As long as the water vapor does not condense into water, it can continue to flow. Therefore, other cooling structures that ultimately condense the water vapor into water, such as cooling fans and semiconductor cooling chips, can be located at the very end of the cooling assembly (or cooling pipeline system) and at a high position. The subsequent condensate can be transported naturally by gravity.

[0051] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the soil crushing device 500 includes a soil crushing wheel 510, which is rotatably connected to the machine body 100.

[0052] The soil-crushing wheel 510 has multiple soil-crushing teeth evenly distributed around its outer circumference. The sharp tips of these teeth allow it to easily penetrate the field, breaking up soil clods and loosening the soil, thus facilitating the subsequent ditching operation by the ditching device 600. The soil-crushing wheel 510 is rotatably connected to the machine body 100. As the machine body 100 moves forward, it naturally drives the soil-crushing wheel 510 to rotate, thereby breaking up soil clods and leveling the field surface through rotational force, creating a loose topsoil layer that aids in subsequent sowing and crop growth. The ditching device 600 is located behind the soil-crushing wheel 510. It should be understood that multiple soil-crushing wheels 510 (soil-crushing devices 500) can be provided, with multiple soil-crushing wheels 510 spaced apart in the left-right direction (with a predetermined distance between adjacent soil-crushing wheels 510). Correspondingly, behind each soil-crushing wheel 510 (soil-crushing device 500), a furrowing device 600 (two opposing furrowing discs 610), a synchronous soil covering and sowing drip irrigation device 700 (a mixing and discharging component 760), and a compaction device 800 (a compaction wheel 810) and other supporting components are provided. The predetermined distance between each soil-crushing wheel 510 allows for precise control of the spacing and sowing amount, reducing missed sowing and double sowing. Providing multiple soil-crushing wheels 510 and other supporting components can improve the sowing operation effect. In this embodiment, six are provided, so soil can be covered and sown in six furrows simultaneously, ensuring uniform coverage of the base soil, while precisely controlling the spacing and sowing amount, reducing missed sowing and double sowing.

[0053] Reference Figure 2 and Figure 5 In some embodiments of the present invention, the trenching device 600 includes two trenching discs 610 arranged opposite to each other, both of which are fixedly connected to the machine body 100; the distance between the two trenching discs 610 gradually increases along the front-to-back direction.

[0054] Both furrowing discs 610 are located behind the soil-breaking device 500, and the synchronous soil-covering seeding drip irrigation device 700 (mixing and discharging component 760) is located between the two furrowing discs 610. At the very front and front of the two furrowing discs 610, the distance between the two furrowing discs 610 is very small, even to the point that the two furrowing discs 610 are directly touching (zero distance). As the machine body 100 (seeder) moves forward, the front part of the furrowing discs 610 cuts into the soil in a certain area, forming a soil crack. As the machine body 100 continues to move forward, the rear parts of the two furrowing discs 610 gradually cut into the soil in that area, thereby widening the soil crack and forming a furrow. Since the furrowing disc 610 is fixedly connected to the machine body 100, its depth of penetration into the soil (depth of the furrow) and the width of the furrow separating the soil (width of the furrow; approximately the maximum distance between the two furrowing discs 610, which remains constant since both are fixedly connected to the machine body 100) remain unchanged. This ensures precise sowing, resulting in a similar sowing depth, which improves seed germination and seedling rates. In particular, it solves the problem of inconsistent sowing depth caused by uneven clay soil texture and tendency to clump. Specifically, in this embodiment, the furrowing device 600 penetrates the soil, creating a furrow 12cm deep and 15cm wide.

[0055] Reference Figure 3 , Figure 5 and Figure 7 In some embodiments of the present invention, the synchronous soil covering and sowing drip irrigation device 700 includes a fan 710, a seed storage component 720, a seed dispensing pipe 730, a substrate soil storage component 740, a soil discharge pipe 750, a drainage pipe 430, and a mixing and discharging component 760. One end of the seed dispensing pipe 730 is connected to the fan 710, and the other end of the seed dispensing pipe 730 is connected to the mixing and discharging component 760. The seed storage component 720 is connected to the seed dispensing pipe 730 through an opening in the pipe wall of the seed dispensing pipe 730. One end of the soil discharge pipe 750 is connected to the substrate soil storage component 740, and the other end of the soil discharge pipe 750 is connected to the mixing and discharging component 760. One end of the drainage pipe 430 is connected to the hydrogen energy power unit 200 (fuel reactor 220), and the other end of the drainage pipe 430 is connected to the mixing and discharging component 760.

[0056] The seed storage component 720 is mainly used for storing seeds. Seeds in the seed storage component 720 fall into the seed dispensing pipe 730 through an opening in the pipe wall (by gravity or driven by other components, such as a motor-driven seed dispensing wheel or by being sucked down by the low pressure generated by the fan 710). Driven by the airflow from the fan 710, the seeds move along the seed dispensing pipe 730 and eventually enter the mixing and dispensing component 760. It should be understood that the seed storage component 720 may include a seed storage box specifically for storing seeds, and may also include other components such as a seed dispensing box, a seed dispensing wheel, and a seed metering device. The upper end of the seed metering box is connected to the opening at the bottom of the seed storage box, and the lower end of the seed metering box is connected to the seed metering pipe 730 through an opening in the pipe wall of the seed metering pipe 730. The seed metering wheel is set inside the seed metering box and is rotatably connected to the seed metering box. The seed metering motor is driven by the seed metering wheel and is electrically connected to the control system (control element). Seeds in the seed storage box fall into the seed metering box by gravity. The seed metering motor actively controls the seed metering wheel to rotate or stop, achieving intelligent seed metering, thereby controlling the specific time and amount of seed metering, and thus metering in batches to accurately control the seed sowing spacing and the amount of seeds sown each time. Alternatively, the fan 710 is electrically connected to the control system (control element). It should be understood that the seed metering pipe 730 can also be equipped with a main seed metering pipe section 732, a seed distributor 733, and multiple sub-seed metering pipe sections 734. The mixing and discharging components 760 are correspondingly equipped with multiple sub-seed metering pipe sections 732. One end of the main seed metering pipe section 732 is connected to a ventilator 710 (one end and front end of the seed suction pipe section 731 are connected to the ventilator 710, and the other end and rear end are connected to one end of the main seed metering pipe section 732). The other end of the main seed metering pipe section 732 is connected to the inlet of the seed distributor 733. The seed distributor 733 has multiple outlets, each outlet corresponding to one end of a sub-seed metering pipe section 734. The other end of the sub-seed metering pipe section 734 is correspondingly connected to a mixing and discharging component 760. Through this arrangement, seeds can be evenly distributed to each sub-seed metering pipe section 734 and the mixing and discharging component 760. Within 60, multi-row synchronous sowing is achieved, improving sowing efficiency. Furthermore, the height of the other end of the main seeding tube 732 is higher than the height of one end of the seeding tube 730 (or, the main seeding tube 732 is provided with an upwardly curved section). This allows some heavier materials (clods of soil, clustered seeds, larger insects) in the seed storage component 720 (seed storage box) to be prevented by wind from being carried through the other end of the main seeding tube 732 into the seed divider 733 due to their greater gravity. This allows impurities and unsuitable parts of the seeds to be separated in advance, preventing these materials from being sown and improving sowing quality. Of course, this setting is suitable for sowing lighter seeds, such as chili seeds.

[0057] The substrate soil storage component 740 (soil storage cylinder) is mainly used to store substrate soil. Under the action of gravity, the substrate soil in the substrate soil storage component 740 moves along the soil discharge pipe 750 and eventually enters the mixing discharge component 760. It should be understood that the substrate soil storage component 740 may include a soil storage cylinder specifically for storing substrate soil. The substrate soil storage component 740 may also include other components, such as a soil discharge door that is movably connected to the bottom opening of the soil storage cylinder. The soil discharge door is connected to a soil discharge motor, a soil discharge cylinder, and other drive components (which are connected to the control elements of the control system) to control the opening or closing of the bottom opening of the soil storage cylinder, thereby realizing intelligent interval soil discharge.

[0058] The drain pipe 430 is connected to the hydrogen energy power unit 200 (fuel reactor 220), so that the water produced by the reaction of the hydrogen energy power unit 200 can be used for drip irrigation of seeds, increasing the seed germination rate and seedling rate. The other end of the drain pipe 430 can be connected to the first channel 761 of the mixing and discharge component 760, or the mixing and discharge component 760 can also have a third channel, with the other end of the drain pipe 430 connected to the third channel.

[0059] It is important to understand that soil removal can continue as the seeder moves forward, or it can continue for a period of time before and after seed removal. After a period of soil removal (pre-covering soil operation), seed removal, drip irrigation, and soil removal can be carried out simultaneously, so that the removed seeds fall on the pre-laid substrate soil (covering soil). Then, water is dripped onto the seeds, and the substrate soil continues to cover the seeds, giving them a thin layer of soil. This setup allows sowing and drip irrigation to be carried out simultaneously, and the presence of substrate soil both under and above the seeds can increase the seed germination rate and seedling survival rate.

[0060] Reference Figure 5 and Figure 6 In some embodiments of the present invention, a first channel 761 and a second channel 762 are provided in the mixing and discharging component 760. A spiral conveying shaft 770 is provided in the second channel 762. The other end of the seed discharge pipe 730 (drainage pipe 430) is connected to the first channel 761 (inlet), and the other end of the soil discharge pipe 750 is connected to the second channel 762 (inlet). The spiral conveying shaft 770 is disposed in the second channel 762 and is rotatably connected to the mixing and discharging component 760.

[0061] The spiral conveyor shaft 770 is configured to break up the substrate soil and make the base soil coverage more uniform. Specifically, the spiral conveyor shaft 770 includes a rotating shaft 771 and a spiral belt 772 extending downward around the rotating shaft 771. The inner side (or inner edge, inner end) of the spiral belt 772 is connected to the outer wall of the rotating shaft 771. The rotating shaft 771 is rotatably connected to the mixing and discharging component 760. The mixing and discharging component 760 is also provided with a spiral drive component, which is pulverizedly connected to the rotating shaft 771. The spiral drive component is used to drive the rotating shaft 771 to rotate, thereby driving the spiral belt 772 to rotate. Furthermore, the mixing and discharging component 760 is also provided with a first bevel gear and a second bevel gear. One end of the first bevel gear is pulverizedly connected to the spiral drive component, and the other end of the first bevel gear meshes with one end of the second bevel gear. The other end of the second bevel gear is connected to the rotating shaft 771.

[0062] When the spiral conveyor shaft 770 rotates, on the one hand, the uppermost end of the spiral belt 772 acts like a continuously rotating cutter, which can cut and impact the falling substrate soil, thereby breaking and scattering the substrate soil. Especially for large pieces of substrate soil, if the approximate diameter of the large pieces of substrate soil is larger than the interval between the spiral belts 772 (similar to the pitch of a screw thread), they cannot enter the spiral belt 772 and can only remain at the uppermost end of the spiral belt 772, where they are continuously cut and impacted, eventually being broken into smaller pieces of substrate soil before entering the spiral belt 772. On the other hand, at the lowermost end of the spiral belt 772, due to the continuous rotation of the spiral belt 772, the outlet of the substrate soil from the spiral belt 772 is constantly changing. Combined with a certain degree of centrifugal force provided by the spiral belt 772, the substrate soil that comes out can be scattered in a certain area below the second channel 762, rather than completely accumulating under the second channel 762 to form a soil mound. Therefore, the substrate soil can be covered more evenly, which is convenient for seed planting and improves the seed germination rate and seedling rate.

[0063] Furthermore, a sonar sensor 780 is also installed on the mixing and emission component 760, which is located between the two furrowing discs 610. The sonar sensor 780 is electrically connected to the control element of the control system. The sonar sensor 780 can measure the furrowing depth of the furrowing device 600 and the depth of the substrate soil pre-covered by the synchronous soil covering and sowing drip irrigation device 700. Based on the furrowing depth of the furrowing device 600, the thickness of the substrate soil pre-covered by the synchronous soil covering and sowing drip irrigation device 700 is controlled, and the depth after covering the substrate soil is detected in real time. After reaching the predetermined sowing depth, the sowing, drip irrigation, and continued soil covering are controlled in a timely manner, thereby achieving precise sowing and ensuring that the sowing depth is basically the same, which is beneficial to improving the seed germination rate and seedling rate; in particular, it can solve the problem of inconsistent sowing depth caused by the uneven texture and easy clumping of clay soil in traditional methods.

[0064] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the seed metering tube 730 is provided with a seed suction tube section 731 (the seed suction tube section 731 extends from front to back). Along the direction from front to back, the inner diameter of the seed suction tube section 731 first decreases and then increases. The seed storage component 720 communicates with the seed metering tube 730 through an opening in the middle tube wall of the seed suction tube section 731.

[0065] The inner diameter of the seed suction tube section 731 first decreases and then increases. The opening in the middle of the tube wall of the seed suction tube section 731 is roughly located in the area where the inner diameter of the seed suction tube section 731 is the smallest. Therefore, the Bernoulli principle can be used to make the seeds discharged by the seed storage component 720 more easily sucked into the seed suction tube section 731, and they are less likely to get stuck or stick to the side wall of the component or the connecting tube wall.

[0066] Furthermore, the seed storage component 720 is connected to the seed discharging pipe 730 through an opening on the top of the middle section wall of the seed suction pipe segment 731. A cleaning opening is provided on the bottom of the middle section wall of the seed suction pipe segment 731, and a cleaning door 735 is installed at the cleaning opening. The cleaning door 735 is movably connected to the seed suction pipe segment 731, and can close or open the cleaning opening. The cleaning opening and cleaning door 735 allow for timely cleaning when too many seeds fall or accumulate excessively over a long period, preventing blockage of the seed suction pipe segment 731. Heavier substances (debris) accumulated in the seed discharging pipe 730 can also be cleaned through this opening. For example, the fan 710 can rotate in the opposite direction to suck them in, or water or air can be used to backwash the other end of the seed discharging pipe 730, causing the debris to move towards one end of the seed discharging pipe 730 (the end connected to the fan 710) and eventually fall out when passing through the cleaning opening, thus completing the cleaning process.

[0067] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the pressing device 800 includes a pressing wheel 810, which is rotatably connected to the machine body 100.

[0068] The press roller 810 is located behind the synchronous soil covering and sowing drip irrigation device 700 (mixing and discharging component 760). In some embodiments, a V-shaped annular groove is provided on the outer peripheral surface of the press roller 810, which can push the soil on both sides to the middle and also prevent the seeds in the middle from being crushed to a certain extent.

[0069] It should be understood that the compaction device 800 may also include a scraper 820, one end of which is threadedly connected to the frame 110 of the machine body 100, and the other end of which is located on the outer side of the outer circumferential surface of the compaction wheel 810 (i.e., along the radial direction of the compaction wheel 810, on the side away from the center of the compaction wheel 810). One end of the scraper blade 820 is threadedly connected to the frame 110 of the machine body 100. Specifically, the frame 110 of the machine body 100 is equipped with a threaded rod, and one end of the scraper blade 820 is equipped with a connecting through hole. The threaded rod passes through the connecting through hole and is threadedly connected to a nut. Therefore, by loosening the nut, the scraper blade 820 can rotate, thereby adjusting the height of the other end of the scraper blade 820 from the ground. The other end of the scraper blade 820 is located on the outer side of the outer circumference of the press wheel 810. By lowering the other end of the scraper blade 820, when the seeder (machine body 100) moves forward, it can scrape a certain depth (or a layer) of soil into the trench, that is, above the substrate soil and seeds. Covering the seeds with an additional layer of native soil increases their protection, especially preventing weed seeds, insects, and other pests from falling directly onto the surface of the substrate soil, using it for growth, damaging the nutrients in the substrate soil, and affecting seed growth. Furthermore, it cleans the outer surface of the roller 810, particularly useful in clay soil areas where clay soil is highly adhesive and some clay from the outer side of the substrate soil easily adheres to the outer surface of the roller 810, affecting its compaction. The scraper 820 can scrape off the thicker layer of clay from the outer surface of the roller 810 as it rotates, preventing it from interfering with the roller's operation.

[0070] Reference Figure 1 In some embodiments of the present invention, the control system includes a GPS locator, radar, a vision sensor, and a control element, wherein the GPS locator, radar, vision sensor, and hydrogen energy power unit 200 (electric motor) are all electrically connected to the control element.

[0071] GPS locators enable automatic positioning, facilitating navigation and route planning to prevent missed planting. Radar and vision sensors can detect obstacles in a timely manner, allowing for obstacle avoidance or emergency stopping to prevent damage to the seeder and to protect animals and personnel in the field. Furthermore, the control components can connect to other parts, such as a 780 sonar sensor for real-time measurement and calibration of planting depth, a seed metering motor (fan) for intelligent seed metering control, and a steering assembly for intelligent steering. By incorporating these devices, largely unmanned and intelligent operation can be achieved, improving planting efficiency, reducing operating time, and lowering labor costs.

[0072] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, the sowing method using the aforementioned seeder includes the following steps:

[0073] Replenish the hydrogen-powered device 200 with liquid hydrogen;

[0074] The synchronous soil covering and sowing drip irrigation device 700 is loaded with crop seeds (hereinafter referred to as seeds) and substrate soil;

[0075] The control system drives and controls the machine body 100 to move forward via the hydrogen energy power unit 200. When the machine body 100 moves forward, the soil breaking device 500 breaks up the field soil, the ditching device 600 cuts into the broken field soil to open a ditch, and the synchronous soil covering and sowing drip irrigation device 700 covers a layer of substrate soil (a thicker layer of soil) in the ditch. The synchronous soil covering and sowing drip irrigation device 700 sows crop seeds on the substrate soil, and at the same time continues to cover the substrate soil (a thin layer of soil), and simultaneously uses water transmitted from the hydrogen energy power unit 200 to drip irrigate the crop seeds. The compaction device 800 compacts the soil.

[0076] In a specific embodiment, before operation, hydrogen is charged into the four liquid hydrogen storage tanks 210 at the rear of the seeder to ensure that the fuel cell can work continuously for more than 8 hours. The seedling substrate soil is loaded into the substrate soil storage component 740 (soil storage cylinder), and the seeds are loaded into the seed storage component 720. The GPS positioning, radar obstacle avoidance and other sensors are adjusted on the APP, and the preset planting depth is 10cm, row spacing is 50cm and hole spacing is 20cm. During operation, the equipment automatically checks itself and starts. The front soil crushing wheel 510 breaks up soil clods and levels the field surface to form a 15cm loose tillage layer. The ditching disc 610 cuts into the soil to open a 12cm deep and 15cm wide ditch. The soil discharge pipe 750 outputs a 2cm thick substrate layer through the six independent mixing discharge components 760 at the rear and the spiral conveyor shaft 770. The seed discharge pipe 730 releases pepper seeds. At the same time, the water purified by the fuel cell reaction is drip-irrigated and covered with a thin layer of substrate soil. Finally, the compaction wheel 810 compacts the soil.

[0077] The sowing method of this invention completes the soil breaking, ditching, covering, sowing, drip irrigation, and compaction operations in one go, which is highly efficient. Irrigation and sowing are synchronized, and the seed germination rate and seedling rate are improved by covering with substrate soil, which also saves the cost of seed trays and nutrient soil. The sowing process uses hydrogen power, which has zero carbon emissions, and the reaction water can be recycled and purified for drip irrigation, which meets the requirements of green and sustainable development. The control system is connected to the hydrogen power unit 200 and the machine body 100, which can intelligently control the seeder to operate automatically and sow, saving manpower and making sowing more precise.

[0078] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
