[0037] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] This application provides a dry direct seeding device for rice, used for ditching, sowing, and covering with soil to complete the dry direct seeding of rice. The specific implementation process of this application is described below.

[0039] Please see Figs. 1-3 This application provides a dry direct seeding device for rice, comprising:

[0040] Suspension mechanism, ditching mechanism, sowing mechanism, frame 01, and soil covering mechanism;

[0041] The suspension mechanism is mounted on frame 01 and is used to connect to an external power mechanism.

[0042] The trenching mechanism is connected to the frame 01 and is located below the suspension mechanism;

[0043] The sowing mechanism is mounted on the frame 01, and the soil covering mechanism is connected to the frame 01, with the soil covering mechanism located below the sowing mechanism.

[0044] The device is connected to an external power source (such as a tractor) via a suspension mechanism, which provides power to propel the entire device forward. As the device moves forward, a furrowing mechanism located below the suspension mechanism creates furrows on the ground for sowing. The furrowing mechanism may consist of rotating blades or plowshares; as the device moves, the blades or plowshares turn over the soil, forming neat furrows and providing suitable positions for subsequent sowing.

[0045] The sowing mechanism is mounted on frame 01. After furrowing is completed, the sowing mechanism evenly sows rice seeds into the furrows according to a specific sowing rate and spacing. The sowing mechanism stores the seeds and discharges a measured amount of seeds into the furrows. Below the sowing mechanism, the soil covering mechanism covers the seeds with soil turned over during furrowing after sowing, completing the soil covering operation. The soil covering mechanism can be devices such as scrapers or rollers that scrape soil back or roll it onto the seeds, covering them to protect them and promote germination.

[0046] In this embodiment, multiple processes such as ditching, sowing, and covering are integrated into one operation, completing several key steps of rice sowing in a single pass. Compared to traditional manual or step-by-step sowing methods, this significantly reduces working time and labor input, improves sowing efficiency, and facilitates mechanized operations for large-scale dryland rice cultivation. The ditching mechanism creates furrows of relatively uniform depth and width, providing a good implantation environment for the seeds. The sowing mechanism controls the amount and spacing of seeds, ensuring even distribution and promoting the later growth and development of rice. The covering mechanism evenly covers the seeds with a relatively consistent soil thickness, aiding seed germination and growth, and reducing problems such as seed exposure or excessive depth caused by uneven soil covering. The suspension mechanism allows the device to adapt well to different external power sources and terrain conditions.

[0047] In an optional embodiment, the trenching mechanism includes a trencher 02, a fixing block 03, and a first retaining plate 04;

[0048] The first retaining plate 04 is connected to the frame 01, and the trencher 02 is fixed to the side of the first retaining plate 04;

[0049] The fixing block 03 is connected to the rear of the trencher 02 and the top of the first retaining plate 04 respectively. The fixing block 03 is used to provide support for the trencher 02.

[0050] The first retaining plate 04 is connected to the frame 01, and the trencher 02 is fixed to the side of the first retaining plate 04 to ensure that the trencher 02 is kept in the correct position during operation, so that the trencher 02 can accurately cut into the soil to carry out trenching operations.

[0051] As the direct seeding device moves forward under the drive of an external power mechanism, the furrow opener 02 cuts into the soil along with the device. The shape and structure of the furrow opener 02 are designed to effectively cut the soil and push it to the sides or rear, forming furrows for sowing. The end of the furrow opener 02 that contacts the soil has a certain degree of curvature and is not perpendicular to the soil. During furrowing, the furrow opener 02 controls the furrow depth to a relatively shallow range (10-15 cm), ensuring that the rice seeds are in a shallow soil layer after being covered with soil, facilitating germination. The end of the furrow opener 02 that does not contact the soil also has a certain degree of curvature, allowing the soil to be pushed backward along the furrow opener 02 after it has cut the soil.

[0052] The fixing block 03 is connected to the rear of the end of the trencher 02 that is not in contact with the soil and above the first retaining plate 04, respectively, and serves to support the trencher 02. During the trenching process, the trencher 02 will be subject to the resistance and reaction force of the soil. The fixing block 03 can transfer these forces to the first retaining plate 04 and the frame 01, ensuring the stability of the trencher 02 and preventing it from shaking or shifting during operation, thereby ensuring that the depth and width of the trench are uniform.

[0053] In this embodiment, the trenching function is achieved through a simple combination of the first retaining plate 04, the trench opener 02, and the fixing block 03. Meanwhile, the design of the trench opener 02 being fixed to the side of the first retaining plate 04 allows it to cut into the soil in a stable posture, resulting in neater trench walls and better control over the depth and width of the trench, which is beneficial for subsequent sowing and covering operations.

[0054] The first retaining plate 04 not only provides installation support for the trencher 02, but also serves as a soil retainer. During the trenching process, it can prevent excessive soil accumulation around the trencher 02, and at the same time, it can guide the soil to the sides or rear, creating favorable conditions for subsequent backfilling operations.

[0055] In an optional embodiment, the dry direct seeding device further includes support wheels 05;

[0056] The support wheel 05 is located on the side of the first retaining plate 04 and is used to support the first retaining plate 04 and the trencher 02.

[0057] Support wheels 05 are mounted on the side of the retaining plate. When the trencher 02 cuts the soil, the support wheels 05 bear part of the weight of the retaining plate and the trencher 02, preventing the first retaining plate 04 from contacting the ground and the trencher 02 from sinking too deep into the soil, thus ensuring the stability of the retaining plate and the trencher 02 during operation. The support wheels 05 also assist the dry direct seeding device in its movement. Simultaneously, the relatively fixed position of the support wheels 05 ensures that the trencher 02 moves in the predetermined direction, creating straight and uniform trenches.

[0058] In this embodiment, the support wheel 05 provides stable support on the side, reducing swaying and offset, keeping the trencher 02 in the correct working position, and ensuring a more uniform trench depth and width. The support wheel 05 can automatically adjust its height according to the undulation of the ground, enabling the trencher 02 and the retaining plate to maintain a relatively stable working state under different terrain conditions.

[0059] In an optional embodiment, the seeding mechanism includes a seeding tube 06 and a seeding box;

[0060] The seed box is fixed on the frame 01, and the seed tube 06 is set on one side of the seed box;

[0061] The seeding tube 06 is tilted downwards and its opening faces the furrowing mechanism.

[0062] The seeding box is fixed on the frame 01 and is used to store a large number of rice seeds. The seeding tube 06 is located on one side of the seeding box, and its downward tilt design allows the seeds to slide down naturally along the seeding tube 06 under the action of gravity. Since the opening of the seeding tube 06 faces the furrowing mechanism, the sliding seeds will fall accurately into the furrows opened by the furrowing mechanism, thereby achieving precise seeding.

[0063] In this embodiment, the tilt angle and opening direction of the sowing tube 06 ensure that the seeds are accurately sown into the pre-drilled furrows by the furrowing mechanism, achieving precise positioning sowing. The sowing box can store a sufficient number of seeds, reducing the frequency of seed additions and improving sowing efficiency. The sowing box provides a relatively enclosed storage environment for the seeds, preventing them from being affected by external environmental factors such as wind, rain, and sun exposure, thus protecting the quality and viability of the seeds. Simultaneously, during the sowing process, the seeds slide down the sowing tube 06, avoiding excessive collisions and friction with external objects, reducing the possibility of seed damage.

[0064] In an optional embodiment, the seeding box includes a box body 07 and a box cover 08;

[0065] The box 07 is fixed on the frame 01, and the box cover 08 is set on the box 07. The box 07 is used to hold the seeds to be sown.

[0066] The container 07 is fixed to the frame 01, forming a stable container structure that provides storage space for the rice seeds to be sown. Because the container 07 is firmly connected to the frame 01, the container 07 remains relatively stationary during the operation of the dry direct seeding device, ensuring that the seeds will not spill out due to shaking.

[0067] The lid 08 is located on the box body 07. Seeds can be added to the box body 07 by opening the lid 08, or the lid 08 can be opened when it is necessary to clean or inspect the inside of the box body 07. When the lid 08 is closed, it fits tightly with the box body 07, sealing the seeds inside the box body 07 and preventing external factors from affecting the seeds.

[0068] In this embodiment, the operator only needs to open the lid 08 to pour the seeds into the container 07, eliminating the need for complicated procedures. Simultaneously, the lid 08 can be easily opened before or during sowing to check the remaining seed quantity and replenish seeds as needed. When the lid 08 is closed, it effectively prevents external dust, debris, rainwater, etc., from entering the container 07, avoiding seed contamination, dampness, or spoilage. Furthermore, the lid 08 can also reduce the impact of light and temperature changes on the seeds to a certain extent, providing a relatively stable storage environment.

[0069] In an optional embodiment, a seed metering wheel 09 is provided at the connection between the seeding tube 06 and the box 07. The seed metering wheel 09 is used to evenly discharge the seeds in the box 07.

[0070] The seed metering wheel 09 is installed at the connection between the seeding tube 06 and the box 07. When the seed metering wheel 09 rotates, its teeth or grooves contact the seeds inside the box 07. As the seed metering wheel 09 rotates continuously, the teeth or grooves pick up a certain amount of seeds one by one and carry them into the seeding tube 06. Because the rotation speed of the seed metering wheel 09 is relatively stable, and the size and spacing of the teeth or grooves are uniform, the amount of seeds picked up and discharged each time is also relatively uniform, thus achieving the goal of evenly distributing the seeds in the box 07 into the seeding tube 06, and finally evenly sowing them into the prepared furrows.

[0071] In this embodiment, the seed metering wheel 09 can control the number of seeds discharged each time, ensuring a uniform sowing amount and avoiding the problem of uneven sowing amount that may occur with manual sowing or other simple sowing methods.

[0072] In an optional embodiment, the seeding tube 06 is tilted downwards at 30 to 45 degrees.

[0073] The seeding tube 06 is tilted downwards at an angle of 30 to 45 degrees. This is mainly due to gravity, allowing the seeds to slide naturally down the inclined inner wall of the seeding tube 06 under their own weight. This angle range ensures that the seeds have sufficient gravitational force to slide smoothly without causing them to slide too fast. This allows the seeds to be discharged from the opening of the seeding tube 06 at an appropriate speed and posture, accurately falling into the furrows prepared by the furrowing mechanism.

[0074] In this embodiment, an inclination angle of 30 to 45 degrees allows the seeds to form a more stable parabolic trajectory during their descent, resulting in a more even distribution of seeds within the furrow. A suitable inclination angle also reduces the mutual compression and jamming of seeds within the sowing tube 06, effectively preventing seed blockage.

[0075] In an optional embodiment, the suspension mechanism includes a suspension arm 10 and a connecting portion 11;

[0076] The bottom end of the suspension arm 10 is connected to the frame 01, and the top end of the suspension arm 10 is connected to the connecting part 11, which is used to connect to an external power mechanism.

[0077] The bottom end of the suspension arm 10 is connected to the frame 01, and the top end is connected to the external power mechanism through the connecting part 11. When the external power mechanism is started, the generated power is transmitted to the suspension arm 10 through the connecting part 11, and then transmitted from the suspension arm 10 to the frame 01, thereby driving the entire dry direct seeding device to move.

[0078] In some cases, the suspension arm 10 can be adjusted at a certain angle relative to the connecting part 11 or the frame 01. This allows the dry direct seeding device to adjust the tilt angle of the device according to different terrain conditions, such as the slope and undulation of the field, to ensure that the sowing, ditching and other operating components maintain a suitable angle and distance from the ground.

[0079] In this embodiment, the connecting part 11 provides a connection interface for an external power mechanism, enabling the dry-seeding device to connect to an external power mechanism, such as a tractor. The suspension arm 10 securely connects the frame 01 to the external power mechanism through the connections at both ends.

[0080] In an optional embodiment, the soil covering mechanism includes a leveling wheel 12 and tracks 13;

[0081] The leveling wheel 12 is connected to the frame 01, and the track 13 is fitted on the surface of the leveling wheel 12.

[0082] As the direct seeding device moves through the field, the leveling wheel 12 connected to the frame 01 rolls with the device. The track 13, fitted onto the surface of the leveling wheel 12, also rotates and contacts the ground. During the device's movement, the track 13 compacts and levels the soil after furrowing and sowing, ensuring close contact between the soil and seeds and creating a favorable soil environment for germination and growth.

[0083] In this embodiment, the compaction of the soil by the track 13 makes the soil around the seeds more compact, reducing the gaps between the seeds and the soil. The rolling of the track 13 can smooth the soil surface, making the soil cover thickness uniform and avoiding situations where the soil cover is too thick or too thin. The structure of the leveling wheel 12 and the track 13 can adapt to soils of different textures and moisture levels. Whether it is clay soil or sandy soil, a better soil cover effect can be achieved by adjusting the pressure of the leveling wheel 12 and the rotation speed of the track 13.

[0084] In an optional embodiment, a second retaining plate 14 is provided between the soil covering mechanisms, and the second retaining plate 14 is connected to the frame 01.

[0085] The second retaining plate 14 is connected to the frame 01 and is located between the soil covering mechanisms. During the soil covering operation, as the leveling wheel 12 and the track 13 compact and level the soil, the soil tends to flow to both sides. The function of the second retaining plate 14 is to block this soil flowing to both sides, keeping it within the range of the sowing row, preventing excessive soil dispersion, and ensuring that the soil covering is concentrated above the seeds, forming a uniform and regular soil covering layer.

[0086] In this embodiment, the second retaining plate 14 prevents soil from flowing to both sides, enabling the soil to cover the seed area more accurately and avoiding uneven soil coverage or seed exposure.

[0087] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
