[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] like Figure 1 As shown, the natural grassland forage seed broadcasting and pressing integrated machine of this application includes a seed storage bin 1, an adjustable broadcaster 2, a pressing roller 3, a frame support structure 4, and a ground wheel 5. Through the reasonable design and combination of each component, the technical problem of uneven seed distribution is solved, and the integrated operation of broadcasting and pressing is realized.

[0029] The seed storage bin 1 is a key component for storing forage seeds to be sown. It is installed in the upper part of the machine and securely connected to the frame support structure 4 via fasteners or welding, ensuring that seeds will not leak during storage and that it has sufficient capacity. The interior is covered with a smooth material coating to reduce resistance, and the exterior is equipped with a visual level gauge or sensor for easy observation and replenishment of seeds by the user.

[0030] The adjustable broadcaster 2 is connected to the seed storage bin 1 by a seed delivery pipe 21, forming a continuous seed supply path. The broadcaster itself mainly consists of an adjusting screw, a multi-stage flow divider 22, and an arc-shaped flow guide shroud 23 (see details). Figure 3 The adjusting screw can be rotated to change the width of the sowing opening to meet different sowing density requirements, thus achieving precise flow control during the sowing process. The multi-stage diverting plate 22 on the inner side can evenly distribute the incoming seeds, avoiding localized dense or sparse distribution. The arc-shaped guide hood 23 at the outlet can effectively guide the seeds to the target sowing area and reduce seed blockage caused by friction or other factors.

[0031] The compaction roller 3 is located directly below the adjustable seeder 2 and is used to compact the soil after seed sowing. It has a cylindrical structure, and its surface can be customized with different groove patterns to improve compaction efficiency and adaptability based on specific terrain conditions. Furthermore, it is connected to the frame support structure 4 via a dedicated connecting rod, allowing for flexible rotation and smoother machine operation. The roller also allows for adjustment of the pressure application angle according to the height of the working surface.

[0032] The frame support structure 4 serves as the main skeleton of the overall machine, providing load-bearing and support functions. It connects and secures all other parts and components to their designated positions, forming a coordinated operating system environment. This structure can be made of high-strength steel and undergoes special anti-rust and anti-corrosion treatment, providing reliable durability under long-term stable working conditions. Simultaneously, appropriate spaces and openings are reserved during assembly to accommodate the connection points between the various parts.

[0033] Ground wheels 5 are directly connected to the frame support structure 4, responsible for providing the overall forward driving force of the equipment and supporting its smooth movement. Torque is transmitted through reduction devices such as gearboxes to drive the machine. The design usually considers the diameter and wheel material (such as toothed rubber tires) to overcome the complex road conditions in the field, ensuring sowing accuracy while maintaining efficient traction performance.

[0034] To address the problem of uneven seed distribution, this application utilizes the unique structural characteristics of the adjustable seeder 2. Firstly, by adjusting the width of the seeding opening, the number of seeds dropped per unit area is precisely controlled. Combined with a multi-stage diverter plate 22, the flowing seeds are further subdivided to achieve a more uniform distribution pattern. Secondly, an arc-shaped guide hood 23 assists in smoothing the transport path and reducing the possibility of accumulation. These combined methods effectively improve the chaotic seed distribution situation existing in current technologies, ensuring planting quality.

[0035] like Figure 2 As shown in one embodiment, the seed storage bin 1 of the natural grassland forage seed broadcasting and compaction integrated machine of this application is equipped with a baffle 11, which is installed in the area near the bottom seed outlet of the seed storage bin 1. This structural design avoids clogging caused by the weight of the seed particles themselves or the angle of accumulation. The baffle 11 is mainly composed of one or more plates with a certain inclination angle. These plates are spaced apart on the inner wall of the bin and maintain a certain angle with the horizontal plane to promote seed flow. The function of the baffle 11 is to change the contact relationship between the airflow and the material in the bin, ensuring that the stored seeds flow evenly to the seed delivery pipe 21, further optimizing the seed delivery capacity of the entire device. The installation of this component does not affect the position and functional compatibility of other systems such as the seed delivery pipe 21, ensuring the consistency and coordination of the overall equipment.

[0036] For example, by fixing the baffle 11 to a specific position inside the seed storage bin 1, with one end connected to the inner wall of the bin and the other end suspended and extending towards the center, the number of baffles can be flexibly adjusted according to the storage bin capacity. Specifically, the edges of the baffles are connected to the bin surface by welding or detachable fixing, and a suitable tilt angle is determined based on experimental data to adapt to the needs of forage seeds with different particle characteristics.

[0037] like Figure 2 As shown, in one embodiment, the seed storage bin 1 of the natural grassland forage seed broadcasting and compaction integrated machine of this application adopts a conical funnel structure 12 at the bottom to optimize the overall function of the equipment. This design ensures that the forage seeds stored in the bin move smoothly downward under their own gravity, thereby effectively avoiding seed retention or blockage caused by accumulation. The design of the seed storage bin 1 fully considers the matching of the structure with the actual working environment. Through the conical funnel structure 12, its opening direction is directly aligned with the seed delivery pipe 21 below, thus forming a continuous channel layout, allowing the seeds to smoothly reach the adjustable broadcaster 2.

[0038] For example, during equipment installation, a conical component with a specific tilt angle can be made of metal or high-strength composite material as the bottom structure and fixedly connected to the main body of the seed storage hopper 1. Specifically, the inner wall surface of this conical structure can be smoothed to further reduce frictional resistance that may occur during seed transport. Furthermore, the height and angle of this conical section can be adjusted to accommodate the sowing needs of forage seeds of different particle sizes. For example, for small forage seeds, appropriately reducing the diameter of the opening at the bottom of the cone can improve their aggregation and transport efficiency.

[0039] like Figure 3 As shown, in one embodiment, the adjustable spreader 2 of the natural grassland forage seed broadcasting and compaction integrated machine of this application is equipped with a functional component for optimizing seed flow distribution. Specifically, a rotatable guide blade 24 is added to the original structure inside the adjustable spreader 2. This component is located in the channel between the multi-stage diversion plate 22 and the outlet, and can adjust the flow guidance of the passing seeds according to actual needs. This design helps to reduce the uneven accumulation or poor dispersion of seeds that may occur during the transport of seeds inside the equipment. In addition, the rotatable guide blade 24 and the multi-stage diversion plate 22 work together to further improve the controllability and uniformity of seed flow, so that each seed can fall more accurately to the designated position after leaving the spreader.

[0040] For example, the aforementioned features can be achieved by fixing a movable shaft in the adjustable spreader 2. The movable shaft connects to the rotatable guide vanes 24 and allows the vanes to rotate around the shaft within a certain angle range. This movable shaft can be fixed to the inner wall of the spreader, while the rotation angle can be controlled by an external adjustment mechanism. Through this technical approach, the coordinated operation of the rotatable guide vanes 24, the multi-stage flow divider 22, and the arc-shaped flow guide shroud 23 can meet the flow rate and direction requirements under specific spreading conditions.

[0041] like Figure 5 As shown, in one embodiment, the sowing device of the integrated natural grassland forage seed sowing and compaction machine of this application effectively improves the problem of seed retention by adding a vibration device 25 to the outside of the arc-shaped guide shroud 23. Specifically, the vibration device 25 is installed in the outer area of ​​the arc-shaped guide shroud 23 and is in close contact with its surface. Since the arc-shaped guide shroud 23 is connected to the outlet of the adjustable sower 2, seeds are prone to accumulation due to friction or moisture when passing through this area. Therefore, the added vibration device 25 can break the static friction between seeds and promote smooth seed falling by applying periodic force. The vibration device 25 itself consists of a shell and an internal power drive mechanism, and the entire structure is firmly installed on the arc-shaped guide shroud 23 by fasteners. Its operation depends on the overall equipment power supply system and can be started and stopped in coordination with the main body of the equipment.

[0042] For example, the vibration device 25 can be a combination of a small motor and an eccentric wheel. The motor is mounted on a support base plate, and the eccentric wheel, acting as a vibration source, is connected to the motor shaft. Rotation generates a stable vibration force, which is then transmitted to the arc-shaped shroud 23. The motor can be fixed to the frame support structure 4 via a bracket structure, and its position can be adjusted to ensure that the vibration force directly acts on the effective area of ​​the arc-shaped shroud 23. This method eliminates the need for complex adjustments to the main design while ensuring that the vibration range is reasonably adapted to the shape and size of the shroud.

[0043] like Figure 4 As shown, in one embodiment, the adjustable spreader 2 of the integrated natural grassland forage seed broadcasting and compaction machine of this application includes a bidirectional synchronous adjustment mechanism 26 for precisely adjusting the width of the broadcasting opening. This mechanism is located inside the adjustable spreader 2 near the broadcasting opening, and its design aims to achieve synchronous adjustment of the components on both sides of the broadcasting opening through mechanical transmission. Specifically, this bidirectional synchronous adjustment mechanism 26 consists of a central drive component and linkage structures at both ends. These linkage structures are connected to the left and right sides of the broadcasting opening respectively to ensure synchronicity and stability during the adjustment process.

[0044] The core component of the bidirectional synchronous adjustment mechanism 26 is a device with symmetrical transmission characteristics. Its central drive component is typically in the form of a screw, which converts mechanical displacement through rotation, thereby driving the linkage structure. In addition, the linkage structure also includes connecting rods and shafts to smoothly and accurately transmit the driving force to both sides of the sowing opening. Specifically, during implementation, these components are fixed to the lower part of the adjustable sower 2 and connected to the movable components on both sides of the sowing opening. To ensure installation reliability and ease of operation, the entire structure needs to be coordinated with the seed delivery pipe 21 and the multi-stage diversion plate 22 to ensure that it does not obstruct the seed flow path and maintains the compact design of the overall equipment.

[0045] For example, a precision-machined threaded rod can be used as the central drive component, paired with a bidirectional threaded sleeve as the linkage component. This not only simplifies the assembly process but also reduces the accumulation of errors during operation. When the operator rotates the external handwheel, the threaded rod drives the two threaded sleeves to move in opposite directions, thus changing the width of the spreading opening. Simultaneously, to ensure synchronization accuracy, guide grooves or guide holes can be added to the linkage structure to limit its range of motion and ensure smooth movement along a predetermined trajectory.

[0046] like Figure 3As shown, in one embodiment, the adjustable spreader 2 of the integrated natural grassland forage seed broadcasting and compaction machine of this application has an elastic baffle 28 on its upper edge. This elastic baffle 28 is installed on the outer edge region of the adjustable spreader 2 and can deform synchronously with the adjustment of the width of the adjustable spreader 2 during the broadcasting process. Specifically, the elastic baffle 28 is made of a material with flexible and tensile properties, and its two ends are firmly connected to corresponding positions on the spreader housing, ensuring that the elastic baffle 28 can automatically adapt to different spreader shape changes when adjusting the broadcasting opening width. Furthermore, to avoid seed leakage during the broadcasting process, the elastic baffle 28 covers the entire outer edge of the spreader, forming a closed barrier.

[0047] For example, the elastic retaining edge 28 can be embedded into the fixing grooves on both sides of the spreader, and flexible sliding interfaces can be provided on both sides to ensure that it always maintains a tight contact during the width adjustment of the spreader. Specifically, this structure uses a combination of elastic material and precise fixing to ensure that the elastic retaining edge 28 fits the outer edge of the spreader consistently.

[0048] In one embodiment, the compaction roller 3 of the integrated natural grassland forage seed broadcasting and compaction machine of this application employs a special structural design. This component is located below the adjustable broadcaster 2, adjacent to the broadcasting area, and is firmly connected to the overall equipment via a frame support structure 4. Specifically, the surface of the compaction roller 3 is specially treated with a plurality of evenly distributed micropores. These micropores enhance the interaction force between soil surface particles during the compaction process. When the equipment moves, the compaction roller 3 rolls and presses against the ground, ensuring that the broadcasted seeds are more tightly embedded in the soil layer. This design effectively improves the seed displacement problem caused by insufficient compaction in traditional equipment.

[0049] To achieve the above features, the press roller 3 can be constructed using the following technical means. For example, microholes with a diameter of approximately 0.5 mm to 1 mm are formed on the surface of the press roller 3 and arranged at equal intervals, with the microhole density adjusted according to actual operational requirements. Furthermore, these microholes can be formed through precision machining or sintering processes, while ensuring the flatness of the outer edge of the press roller 3 to avoid unnecessary damage to the spreading area.

[0050] like Figure 2As shown in one embodiment, the seed delivery pipe 21 of the natural grassland forage seed broadcasting and compaction integrated machine of this application has a built-in filter device, which can effectively intercept larger impurities to improve the seed broadcasting performance of the equipment. Specifically, this filter device is installed inside the seed delivery pipe 21, in the necessary passage between the seed storage bin 1 and the adjustable broadcaster 2. The filter device consists of a filter screen 27 made of flexible material and a fixed frame connected to it, ensuring that it can maintain shape stability and impurity filtering function for a long time during operation. The filter screen 27 is tightly fitted into the fixed frame, and the entire device is assembled into the seed delivery pipe 21 by plugging in, making it easier to disassemble and clean. This layout avoids the problem of additional space occupation and ensures its positive effect on seed delivery efficiency and spreading uniformity.

[0051] For example, a flexible snap-fit ​​structure can be added to the design of the fixed frame to firmly lock the entire filter device into the seed delivery pipe 21 and ensure that the filter screen 27 is flatly attached to the pipe wall. This ensures effective filtration and also allows the user to quickly replace damaged or clogged filter screens 27 as needed. With this installation method, the filter device can operate efficiently and meet actual operational requirements.

[0052] like Figure 5 As shown, in one embodiment, the surface of the ground wheel 5 of the natural grassland forage seed broadcasting and compaction machine of this application is provided with an elastic anti-slip strip 52. The elastic anti-slip strip 52 is installed on the outer periphery of the ground wheel 5, aligned with the radial direction of the ground wheel 5. Specifically, the elastic anti-slip strip 52 is evenly distributed along the surface of the ground wheel 5 and has a certain degree of elasticity and wear resistance. During equipment movement, this design ensures that the friction between the equipment and the ground is effectively improved, making it particularly suitable for muddy or soft natural grassland environments.

[0053] The elastic anti-slip strip 52 is typically made of rubber or silicone, possessing soft and anti-aging properties. It is assembled to the wheel 5 via mechanical inlay or adhesive fastening. This method not only facilitates disassembly and maintenance but also allows for the selection of materials with different hardness and surface textures to meet specific needs based on actual working conditions. For example, in wet and slippery environments, an elastic anti-slip strip 52 with a deep groove design can be selected to enhance grip; in drier areas, the stripe spacing and depth can be adjusted appropriately to balance durability and shock absorption. In terms of connection, the elastic anti-slip strip 52 is directly embedded into the pre-cut groove structure via a snap-fit ​​connector, seamlessly connecting with the wheel 5 to achieve stable structural support and functional expansion.

[0054] In actual operation, when this device is in use, pasture seeds are stored in the seed storage bin 1 and then transported to the adjustable spreader 2 through the seed delivery pipe 21 for uniform spreading. Inside the adjustable spreader 2, the seed flow direction is optimized by a multi-stage diverter plate 22, and blockage is reduced by adjusting the spreading opening width and the arc-shaped guide hood 23 to achieve precise control of the flow distribution. After the seeds are sown onto the grassland soil surface, the compaction roller 3 located below compacts the sown seeds, thereby ensuring effective contact between the seeds and the soil. The overall movement of the equipment is supported by the ground wheels 5, and the frame support structure 4 ensures a stable connection between the components and the smooth operation of the equipment.

[0055] The specific embodiments described above further illustrate the purpose, technical solutions, and beneficial effects of the embodiments of this disclosure. It should be understood that the above descriptions are merely specific embodiments of the embodiments of this disclosure and are not intended to limit the scope of protection of the embodiments of this disclosure.
