[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0028] like Figure 1 As shown, a straw pushing device for use with a no-till machine according to this application includes a frame 1, a front guide plate 2, a cutting disc assembly 3, a pushing auger, and a counterweight 5, among other main components. This device is designed to effectively chop and forward-convey the straw layer scattered in the field during no-till processing, reducing the impact of crop residues on subsequent operations. Furthermore, by optimizing the structure of each component, it ensures high chopping efficiency without slowing down the overall operation.

[0029] The frame 1 serves as the base of the overall structure, integrating all other components and securely connecting to the agricultural machinery—the no-till machine—through suitable mounting interfaces. This ensures that the device can stably follow the main unit's movement, operating smoothly without deviating from the designated path. Furthermore, to adapt to different machine models or varying operational needs, this support structure can be constructed from high-strength materials such as steel, ensuring strength while minimizing weight, thus achieving a balance between flexibility and stability.

[0030] Located in front of the frame 1 is the front guide plate 2. Its function is to provide preliminary treatment to the large areas of crop residue to be processed, guiding and dispersing it to reduce resistance during subsequent processing. For example, the guide plate features a smooth curved surface that gradually widens to both sides, effectively pushing apart clumps of straw that are difficult to break up. Simultaneously, small holes or textures can be incorporated at the bottom to allow it to grip the ground material more firmly during operation, thus more easily propelling the plant debris forward, improving efficiency and maintaining continuous, smooth operation.

[0031] The cutting disc assembly 3 is the key execution unit of this device, directly related to the quality of the final product. It is fixedly installed behind the front guide plate 2 and tightly integrated with the main beam. The assembly itself mainly consists of several sets of professional-grade cutting blades 31 arranged and embedded in a specific manner. To achieve the ideal crushing effect, a staggered placement pattern is adopted in the design, that is, the spacing between two adjacent blades becomes closer as they move forward from the starting point. At the same time, the shape of each individual component is also finely adjusted to have a certain curvature, which facilitates easier and faster cutting operations when materials are fed in and out, and minimizes the frequency of wear. As for the size of the outer circumference, it is gradually increased in an orderly manner from the middle to both ends according to the actual working conditions, thus forming a stepped segmented processing method, ensuring that the force is evenly distributed at each point, which can both increase the number of force application points and maintain the original path of travel without obstruction.

[0032] The auger is used to complete the final stage of the process. In terms of its structure, it is positioned parallel to the cutting mechanism and fixed to the frame. Power drives the shaft to rotate, creating a periodic, alternating oscillation along its length. This generates continuous propulsion pressure, gradually feeding the biomass pellets, which have just undergone the crushing process, into the forward path, thus achieving a continuous and stable transportation task. Specifically, during manufacturing, wear-resistant and corrosion-resistant materials such as stainless steel can be selected, and parameters such as the screw pitch can be appropriately optimized to improve performance during operation, ensuring that each transmission safely, reliably, and accurately achieves the intended goal.

[0033] The device is equipped with a counterweight 5 at the end to improve balance and prevent tilting caused by the reaction forces generated in the previous processes. This further optimizes the operating environment and provides the necessary compaction force to the farmland surface. In terms of material properties, a high-density metal material that is easy to cut and grind can be selected for filling and reinforcement, such as cast iron. These materials ensure appropriate weight, a scientific layout, and ease of installation, disassembly, replacement, and maintenance.

[0034] A straw pushing device for use with no-till machines cleverly solves the problem of how to improve straw crushing results without affecting the overall travel speed: First, the front guide plate 2 breaks down the accumulated obstacles and distributes them evenly; then, the carefully planned cutting equipment quickly breaks down these loosened stalk fragments down to the smallest size; finally, the pushing system is responsible for clearing the roadway, allowing all the debris to leave the designated location and return to the natural ecosystem. This not only improves the output of a single trip but also creates favorable conditions for the subsequent sowing stage.

[0035] like Figure 1 As shown in one embodiment, a straw pushing device for use with a no-till machine according to this application is characterized in that the spacing between the blades 31 in the cutting disc assembly 3 is largest at the central position and gradually decreases to the minimum value on both sides. This arrangement enables gradient cutting without affecting the pushing speed, further enhancing the straw crushing effect. The different spacing between the blades 31 is carefully arranged according to the working requirements and straw distribution, ensuring a reasonable distribution of cutting force throughout the cutting area and improving the consistency and efficiency of the crushing effect.

[0036] This feature was implemented by rationally adjusting the spatial relationship and connection method of each component. Specifically, the cutting disc assembly 3 is located behind the front guide plate 2 and is fixedly connected to the frame 1. The spacing of the blades 31 is set to decrease from the center to both sides. This arrangement ensures a larger feed gap at the central position and increases the cutting frequency on both sides to improve the crushing capacity. At the same time, the outer diameter of the blades 31 at the outer edge of the cutting disc is arranged to gradually increase from the center to the outside, allowing the equipment to perform effective crushing within a wider working range.

[0037] For example, to achieve this feature, the blades 31 on the cutting disc assembly 3 employ a gradually varying spacing design. A larger spacing is maintained between the blades 31 in the central area to facilitate smooth material passage in the initial stage, while the distance between the blades 31 significantly decreases towards the sides to enhance the secondary refining and crushing effect, thus achieving a continuous cutting process from coarse to fine. The entire process not only considers the directionality of straw entry but also fully integrates the material flow pattern for optimized layout, ensuring smooth operation while improving the reliability and adaptability of agricultural machinery.

[0038] like Figure 2As shown, in one embodiment, a transmission assembly 32 is provided between the cutting disc assembly 3 and the pushing auger 4 of the straw pushing device for use with a no-till machine. This transmission assembly 32 is an electric chain drive mechanism that ensures the cutting disc assembly 3 and the pushing auger 4 can operate synchronously to optimize overall operating efficiency. The electric chain drive mechanism achieves efficient power transmission through precise installation and ensures coordinated movement between the two key components.

[0039] The electric chain drive mechanism is located in the area behind the cutting disc assembly 3 and in front of the push auger, and is fixed to the same frame 1. Specifically, the drive assembly 32 includes an electric motor and a chain connecting the two. The chain tightly meshes with gears on both sides and is respectively mounted on the shafts of the cutting disc assembly 3 and the push auger. This design ensures that the push auger can immediately receive power input when the cutting disc is working, and thus begin to effectively transport the shredded material. In addition, the introduction of the electric chain drive mechanism not only simplifies the power distribution path but also reduces the error risk caused by mechanical transmission, while improving the durability and reliability of the system.

[0040] For example, when the no-till machine is started, the electric chain drive mechanism immediately drives the cutting disc assembly 3 to rotate and cut the straw. At the same time, the chain transmits power at the same rate to the pushing auger, and the two work together. This mechanism effectively solves the problem of asynchrony in the operation of traditional devices, improving the quality and smoothness of straw pushing operations.

[0041] like Figure 3 As shown, in one embodiment, the blade 31 of a straw pushing device for a no-till machine has a parabolic tip. This design ensures that the contact point is minimized during the cutting and pushing processes. Specifically, the parabolic design optimizes the contact between the blade 31 and the straw, reducing frictional resistance to a minimum and thus improving cutting efficiency. Furthermore, this arc-shaped design helps reduce resistance variations during cutting, maintaining consistency in the chopping process and avoiding energy waste caused by an excessively large contact area.

[0042] The blades 31 are mounted on the cutting disc assembly 3 in a staggered arrangement, with the spacing between each adjacent blade 31 gradually decreasing and extending along the forward direction. This arrangement allows the blades 31 to work in a gradient pattern, creating an orderly and efficient cutting mode. The outer diameter of the cutting tool gradually increases from the center to both sides, further ensuring the cutting effect and feed capability of each blade 31, while ensuring that the overall feed speed is not affected.

[0043] To achieve the aforementioned features, the installation angle and shape of the blade 31 must be precisely designed and adjusted. For example, during manufacturing, the tip of the blade 31 can be shaped using specialized tools to precisely conform to parabolic geometry. Furthermore, during assembly, strict control must be exercised over each blade 31 on the cutting disc to ensure that the tip of each blade 31 accurately presents the required parabolic shape. This not only effectively reduces friction but also ensures that the equipment maintains optimal operating conditions throughout the process.

[0044] Return to reference Figure 1 In one embodiment, the front guide plate 2 of the straw pushing device for a no-till machine of this application adopts an inclined design with an angle set between 30 and 45 degrees. This specific angle was determined through precise calculations and multiple rounds of testing, aiming to guide and quickly divert the accumulated straw layer in front, thereby effectively preventing the straw from accumulating in front of the cutting area, and ensuring that the blade 31 can smoothly cut into the material to be processed. The front guide plate 2 is located in front of the frame 1 and is firmly fixed to the frame 1, serving as the primary contact point for interacting with the straw layer.

[0045] Specifically, this inclined design allows the straw to be subjected to a certain downward pressure upon contact with the guide plate, causing it to naturally separate and diffuse to the sides or bottom, reducing the flow density entering the working area and improving the overall processing efficiency of the device. Furthermore, the guide plate can be a smooth curved surface or have guiding patterns to further optimize adaptability to different crop types and the guiding effect.

[0046] For example, in practical applications, the ideal tilt angle can be achieved by precisely adjusting the bending and forming process of the precast metal sheet and the position of the mounting bracket. Furthermore, during processing, the flatness and hardness of the component must meet the usage requirements, thus stably and efficiently supporting and guiding the flow path of agricultural residues. The front guide plate 2 is directly welded to the front end of the frame 1 and reinforced with reinforcing ribs to withstand large frictional torques. Simultaneously, to adapt to different agricultural needs, adjustable support components can be considered for flexible adjustment of the specific tilt angle.

[0047] like Figure 4 As shown, in one embodiment, the pusher auger of the straw pushing device for use with a no-till machine according to this application has an added wear-resistant liner 41. Specifically, this wear-resistant liner 41 is specially designed to protect the surface of the auger blades, preventing wear caused by straw, soil, and other debris during operation, ensuring that the pushing device can maintain long-term high-efficiency working performance in harsh environments and maintain its stable feeding function.

[0048] The wear-resistant liner 41 is made of high-strength wear-resistant material. Through precise cutting and forming processes, it is perfectly matched and fixed to the inner wall of the pushing spiral auger, ensuring tight contact between the two and preventing relative displacement or detachment due to external factors. After installation, the liner not only effectively covers the entire spiral working surface, but also takes additional reinforcement measures in the shaft area, thereby ensuring the safety and durability of the overall structure.

[0049] For example, in one specific implementation, to facilitate assembly and maintenance, the wear-resistant liner 41 can be designed as several segmented modules, each fastened together with screws or other quick-connect methods, and sealed to prevent dust from seeping into the gaps and causing damage. When severe wear necessitates replacement, only the corresponding part needs to be disassembled for local repair, saving costs and improving maintenance efficiency. Furthermore, the edges of the liner are specially processed to reduce interference during material conveying, while ensuring smooth and stable rotation of the auger.

[0050] Return to reference Figure 1 In one embodiment, a guide roller 33 is provided at the front end of the cutting disc assembly 3 of a straw pushing device for use with a no-till machine. The guide roller 33 is located between the cutting disc assembly 3 and the front guide plate 2. The outer surface of the guide roller 33 is provided with several rows of raised particles 34 for processing incompletely cut straw. This structure enables pre-compression of the straw, thereby improving the accuracy of subsequent cutting and crushing.

[0051] Specifically, the guide roller 33 is installed in front of the cutting disc assembly 3, maintaining an appropriate distance between them to ensure smooth entry of straw. The outer diameter of the guide roller 33 is slightly smaller than the gap between the end of the front guide plate 2 and the blade 31 of the cutting disc assembly 3, ensuring that the guide roller 33 can rotate freely without interfering with surrounding components. Multiple rows of raised particles 34 are evenly distributed on the surface of the guide roller 33. As the roller rotates, the straw in contact with it will be subjected to pre-pressure, which will initially straighten and tidy up the originally tangled or intertwined straw, which is beneficial to improving the subsequent chopping effect. The number and arrangement of the raised particles 34 can be adjusted based on different working environments, such as crop type and planting row spacing.

[0052] For example, the rotational speed of the guide roller 33 can be adjusted via a linkage mechanism with the main unit, allowing for optimal matching based on crop growth conditions during actual operation. When the machine starts, the guide roller 33 rotates with the transmission system, and the raised particles 34 pre-compress the incompletely cut straw guided by the front guide plate 2, thus feeding the prepared material into subsequent processes and providing favorable conditions for cutting. The entire process is driven by the no-till machine's power unit, eliminating the need for an additional auxiliary power source, simplifying the mechanical structure and reducing energy consumption.

[0053] In one embodiment, the front guide plate 2 of a straw pushing device for a no-till machine is coated with a Teflon anti-stick coating 21. This coating has excellent hydrophobic and anti-stick properties, significantly reducing the probability of straw and other crop residues remaining on the equipment surface. Teflon coatings are widely used in various industrial equipment. Due to their unique material properties, they effectively prevent substances from adhering to the surface, reducing the need for cleaning the guide plate during routine maintenance. For agricultural machinery, this means significantly shortening cleaning time after each operation and reducing corresponding costs. Analysis of the working conditions of existing agricultural machinery reveals that during long-term operation, especially when handling wet, high-fiber crops, a large amount of residue can accumulate, affecting not only the normal operation of the equipment but also potentially accelerating the wear and tear of parts.

[0054] To achieve this characteristic, spraying or dipping processes are incorporated into the design and manufacturing of the front deflector 2 to evenly distribute and firmly adhere the Teflon material layer. The Teflon anti-stick coating 21 needs to form a continuous, dense film on the surface of the front deflector 2, ensuring it does not easily peel off even after long-term outdoor use, thus guaranteeing its long-term stable performance. For example, in the specific manufacturing process, this coating application step can be completed using professional thermosetting spraying technology before the deflector leaves the factory. Furthermore, selecting appropriate undercoating methods also helps improve the adhesion strength and durability of the Teflon coating; for example, fine sanding or chemical pretreatment can enhance the surface roughness and activity of the substrate, thereby improving the application effect of the anti-stick coating.

[0055] The Teflon anti-stick coating 21 is applied to the entire surface of the front guide plate 2 without requiring additional components. This does not affect the design structure or installation position of the guide plate itself, while effectively preventing sticking. Specifically, the thickness of this coating should be set according to the actual working conditions, and it must ensure sufficient adhesion between the coating and the original metal material to maintain long-term functionality. The front guide plate 2 remains fixedly connected to the front of the frame 1, serving as the first barrier to guide the straw to be processed, thus ensuring smooth subsequent cutting and conveying operations. This setup ensures smooth operation of the entire device while minimizing the potential risk of malfunction due to crop residues, improving the reliability of the equipment.

[0056] Return to reference Figure 2In one embodiment, the counterweight 5 of the straw pushing device for a no-till machine can be adjusted in vertical center of gravity. This function is achieved by setting a connecting screw 51 on the counterweight 5. The screw allows the operator to manually adjust the distance between the counterweight 5 and the ground to change its force point and distribution on the entire device. This design ensures that users can flexibly adjust the device in actual working scenarios to meet different tillage conditions. For example, in areas with hard soil, pressure can be increased to make the machine fit more closely to the ground and improve compaction; conversely, in softer soil, the downforce can be reduced to ensure machine stability and reduce the risk of sinking. The components in the device coordinate with each other: the front guide plate 2 guides the material smoothly into the processing section, while the cutter head system undertakes the cutting task and transfers the chopped contents to the conveying section.

[0057] For example, to precisely adjust the pressure applied to the ground under different terrain conditions, the aforementioned feature allows the connecting screw 51 located at the tail mounting point to be rotated using a tool, thereby directly changing the height of the counterweight 5. Specifically, when it is necessary to increase the pressure on the ground, the counterweight 5 is rotated to lower it; conversely, it is adjusted upwards to an appropriate height, thereby optimizing the overall performance of the device. During the adjustment process, the relative position between the counterweight 5 and the frame 1 changes dynamically without affecting the normal operation of other functional modules, ensuring high efficiency and stability from material input to final output.

[0058] like Figure 3 As shown, in one embodiment, the blade 31 of a straw pushing device for use with a no-till machine is configured with a multi-serrated edge structure 311. This structure not only enhances the effect of the blade 31 when performing arc-shaped cutting, but also forms multiple staggered cutting surfaces. The multi-serrated edge structure 311 increases the number and diversity of cutting points during the cutting process by adding multiple small serrations at intervals to the edge of the original blade 31, resulting in a higher crushing success rate for coarser or complex materials, such as thick straw and grass. In addition, the design of this structure ensures that the working area of ​​each serration is different during cutting, which helps to improve cutting efficiency and reduce cutting resistance, avoiding local accumulation or breakage that may be caused by a single cutting mode.

[0059] For example, in terms of technical implementation, the multi-tooth structure 311 is formed along the entire working edge of the blade 31 through precision casting or machining. Appropriate spacing and angle differences are maintained between each tooth to ensure a continuous and staggered cross-section during cutting. During installation, the multi-tooth structure 311 is fixed to a designated position on the cutting disc assembly 3 along with the blade 31. The multi-tooth structure 311 is designed to work collaboratively with the overall cutting system; that is, during rotation, the multi-tooth structure 311 on each blade 31 contacts the material at a preset angle and path, cutting with uniform pressure and speed, thus ensuring efficient operation under different soil and straw mulch conditions.

[0060] like Figure 5 As shown, in one embodiment, a vibration motor 22 is installed at the rear of the front guide plate 2 of a straw pushing device for use with a no-till machine. Specifically, the vibration motor 22 is installed between the front guide plate 2 and the cutting disc assembly 3, and is securely fixed by a bracket to ensure stable operation and effective vibration transmission during operation. The operating frequency of the vibration motor 22 is precisely calibrated so that the entire straw pushing device can perform slight oscillations of appropriate amplitude and frequency. As the main load-bearing component, the front guide plate 2 has an elastic support structure at its bottom, allowing a certain range of vertical movement, thereby transmitting the vibration generated by the motor to various areas of the guide plate.

[0061] This slight vibration helps prevent crop residue from tangling and accumulating on the surface or in the gaps of the guide plate, while also promoting the even distribution of any remaining material. The slight vibration of the guide plate reduces the adhesion of straw and other plant residues, lowering the risk of them getting stuck or tangled during operation. For example, by adjusting the parameters of the vibration motor 22 and the stiffness of the guide plate's support structure, the desired shaking and dispersing of material can be achieved. Furthermore, this mechanism helps ensure that the material to be cut is more evenly and loosely distributed on the guide plate surface, creating favorable conditions for subsequent cutting processes.

[0062] In one embodiment, the blade 31 of a straw pushing device for use with a no-till machine is equipped with a replaceable blade 312. Specifically, this design allows a particular blade 31 to be replaced individually when severely worn, without requiring a major overhaul or replacement of the entire cutting disc assembly 3. The introduction of the replaceable blade 312 not only reduces maintenance costs but also ensures continuous normal operation of the device, thereby improving maintenance convenience and operational efficiency.

[0063] The replaceable blade 312 is mounted on the base of the fixed blade 31 and secured to a specific position on the cutting disc assembly 3 with special fasteners, ensuring its stability and safety. These special designs allow for quick on-site replacement without the need for additional complex tools and procedures. The connection between the replaceable blade 312 and the fixed blade 31 is precisely designed with excellent sealing and vibration resistance, preventing loosening due to vibration during prolonged use.

[0064] Return to reference Figure 3 In one embodiment, for example, the replaceable blade 312 can be fastened to a mounting slot on the fixed blade 31 by a set of high-strength screws. The mounting slot is located at the end of the blade 31, ensuring a tight fit between the two, thereby effectively reducing blade 31 vibration. The blades 31 are staggered, so the mounting slots are also staggered to adapt to the overall cutting disc design. This not only ensures uniform stress on each part of the blade 31 during cutting, but also helps to extend the overall service life of the replaceable blade 312. In addition, to further improve reliability, a layer of cushioning material can be added between the screws and the mounting slot during installation to absorb stress during operation and improve structural stability.

[0065] In actual operation, when this device is in use, the frame 1 supports and connects to the no-till machine, allowing the entire straw pushing device to move together with the main unit. A front guide plate 2 is positioned in front of the frame 1 to guide and disperse the straw layer to be processed, reducing its accumulation resistance. Subsequently, the cutting disc assembly 3 receives the straw that has been pre-processed by the front guide plate 2 and chops it using blades 31. These blades 31 are arranged in a staggered pattern, with the spacing between adjacent blades gradually decreasing and extending in the forward direction, ensuring efficient chopping. The arc-shaped design at the ends of the blades 31 helps reduce friction during cutting and pushing, while the gradient arrangement of the blade outer diameter, gradually increasing from the center to the sides, enhances the cutting force without interfering with the pushing speed. The chopped material is received by the pushing auger and conveyed forward through its rotation. To ensure overall device balance and increase ground compaction, a counterweight 5 is installed at the rear of the frame 1. This entire process allows the straw to be effectively removed and processed before the no-till machine operates, thereby improving the quality and efficiency of subsequent operations.

[0066] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
