Technical Field

[0001] The utility model relates to the technical field of strip tillage machines, in particular to a combined wide and narrow row straw strip tillage machine. Background Art

[0002] In the traditional agricultural production process, the straw left in the field after the fruit is harvested is often crushed and covered with land by a field return machine. This treatment method can increase the organic matter in the soil and retain moisture. However, this method has shortcomings in actual operation, because after returning the straw to the field, only a simple compaction treatment is usually used, which makes it difficult for the operator to accurately understand the density of the soil surface in the subsequent strip tillage operation, making it difficult to grasp the depth of the strip tillage. In addition, the independent steps of straw processing and soil preparation require repeated mechanical operations, which increases the number of operations and further leads to an increase in labor and time costs.

[0003] For this reason, a combined wide and narrow row straw strip tillage machine is proposed to solve the above-mentioned problems. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0030] See also Figure 1-4 , a combined wide and narrow row straw strip tiller according to some embodiments of the utility model is described below.

[0031] The embodiment of the first aspect of the utility model provides a combined wide and narrow row straw strip tiller. In some embodiments of the utility model, such as Figure 1-4 As shown, the tillage machine includes:

[0032] A crushing shell 1 is provided with a crushing roller which is rotatably installed inside the crushing shell 1; the crushing shell 1 is installed on an external carrier to drive the crushing shell 1 to move along a travel direction; along the travel direction, two ports which are connected with the interior are formed on the crushing shell 1, and the crushing roller is located between the two ports to crush the straw passing through the two ports.

[0033] At least one tilling roller is located behind all ports along the traveling direction; the tilling rollers are connected in sequence along the traveling direction and installed on the crushing shell 1; tilling wheels 3 are installed on the tilling rollers; along the traveling direction, the tilling wheels 3 on the tilling rollers gradually increase, and the tilling wheels 3 on adjacent tilling rollers are staggered along the traveling direction.

[0034] The driving mechanism 5 is installed on the upper surface of the crushing shell 1 ; the driving mechanism 5 is connected to the crushing roller through the transmission mechanism 6 to drive the crushing roller to rotate relative to the crushing shell 1 .

[0035] The utility model provides a combined wide and narrow row straw strip tiller, the core part of which is a crushing shell 1, which is a solid shell with a crushing roller installed inside. The crushing shell 1 is designed to withstand high loads and resist various physical impacts in the field; the crushing roller is a heavy cylindrical roller with cutting or crushing blades on the surface. These blades are used to efficiently cut and crush the straw entering through the ports at both ends of the crushing shell 1. The roller is driven by a motor and can rotate at a high speed to ensure continuous and uniform straw crushing.

[0036] As the tiller moves along the field, the straw is introduced through the ports at both ends of the crushing shell 1. These ports are designed to be of moderate width to effectively introduce straw in different positions without manual sorting; once the straw enters the crushing shell 1, the crushing rollers start working. The high-speed rotation of the rollers and the cutting force of the blades quickly crush the straw. In this process, the straw is cut into small pieces, which is convenient for subsequent soil mixing and organic matter decomposition; the crushed straw is output from the other end of the crushing shell 1 and is directly distributed on the soil surface or slightly mixed into the surface soil. This helps to maintain soil moisture and increase soil organic matter.

[0037] The strip tillage roller is one or more rollers installed behind the crushing shell 1, which are arranged along the travel direction of the machine. The main function of the strip tillage roller is to further organize the crushed straw and soil to provide an ideal soil structure for growing crops; multiple tillage wheels 3 are installed on each strip tillage roller. The tillage wheel 3 is a round or cylindrical element fixed to the strip tillage roller, which has the ability to till the soil. In the length direction of the strip tillage roller, the number of tillage wheels 3 gradually increases, which means that from the front end to the rear end of the strip tillage machine, the density of the tillage wheels 3 gradually increases to provide deeper or more detailed soil tillage; the tillage wheels 3 on adjacent strip tillage rollers are staggered along the travel direction. This design can ensure uniform treatment of soil and straw, avoid missing uncultivated strips, and thus enhance the coverage and effect of tillage.

[0038] After the straw crushed by the crushing shell 1 is mixed with the soil, the strip tillage roller starts to work. The main task of the strip tillage roller is to refine and further organize these materials, ensure that the straw is fully mixed into the soil, and enhance the ventilation and water retention of the soil; due to the increasing number and staggered arrangement of the tillage wheels 3 on the strip tillage roller, the machine can gradually deepen the tillage depth during the process of traveling, and the staggered tillage wheel 3 design ensures the uniformity of tillage. This helps to achieve a more uniform seed sowing bed and improve the consistency of crop germination and growth; through the continuous action of the strip tillage roller, the soil structure is optimized, the looseness and air permeability of the soil are increased, which is conducive to the expansion of the root system and the absorption of water and nutrients.

[0039] The drive mechanism 5 is usually composed of one or more electric motors or internal combustion engines, mounted on the surface of the crushing shell 1. The choice of these drive sources depends on the overall design of the machine and the expected operating load; the transmission mechanism 6 connects the drive mechanism 5 and the crushing roller. It may include elements such as belts, chains, gears or couplings, which are designed to effectively transmit power. The design of the transmission mechanism 6 ensures smooth power transmission and reliability of operation.

[0040] The electric motor or internal combustion engine of the drive mechanism 5 generates rotational power after starting. This power is the basis for all mechanical operations of the strip tiller, especially the rotation of the crushing roller; the generated power is transmitted to the crushing roller through the transmission mechanism 6. For example, if a belt drive system is used, the pulley on the motor shaft is connected to the pulley on the crushing roller shaft through a belt, and when the motor starts to rotate, the power is transmitted to the crushing roller through the belt to rotate it; once the power is received, the crushing roller starts to rotate at the set speed. The cutting blades on the roller rotate at a high speed, effectively crushing the straw that passes through the end of the crushing shell 1.

[0041] In summary, in traditional methods, straw processing and soil preparation are carried out separately, requiring multiple mechanical operations. The present invention integrates straw crushing and soil strip tillage into the same process through an integrated design, effectively reducing the number of mechanical operations; in traditional straw processing, it is difficult to control the depth and quality of strip tillage because straw processing and soil preparation are separated. The present invention makes the mixing of soil and straw more uniform and the tillage depth more precise through the design of the strip tillage roller; through the efficient drive and transmission mechanism 6, the present invention optimizes the use of energy and reduces energy consumption, while improving the overall operating efficiency by reducing the number of operations.

[0042] Reducing the number of mechanical operations directly reduces labor and fuel costs. In addition, the integrated processing increases the operating speed and land utilization, further increasing economic benefits; because the straw is effectively cut and evenly mixed into the soil, this increases the organic matter content of the soil, improves the soil's water and fertilizer retention capacity, which is beneficial to the growth of crops and improves the yield and quality of crops; the present invention reduces the impact of agricultural activities on the environment. By effectively utilizing straw, the discharge of agricultural waste is reduced, while soil erosion is reduced, which contributes to sustainable land protection; the design of the strip tiller allows the operator to adjust the depth and density of tillage according to specific conditions, providing greater operational flexibility. This is especially important for adapting to different crops and soil conditions.

[0043] Furthermore, the crushing shell 1 includes a circumferential shell, sealing plates 102 respectively mounted on both ends of the shell, and an assembly rod 103 mounted on the shell, and the assembly rod 103 is responsible for fixing and assembling with an external carrier.

[0044] As can be seen from the above, the circumferential shell is the main body of the crushing shell 1, which is usually cylindrical and made of materials with high strength and wear resistance, such as steel or reinforced plastic, to withstand mechanical stress and prevent wear; a baffle plate 102 is installed at each end of the shell, which closes the opening of the shell to prevent straw and debris from flying out during the crushing process, while supporting internal components such as crushing rollers; the assembly rod 103 is installed on the shell, and its main function is to fix and assemble the crushing shell 1 with an external carrier (such as a tractor or other mobile machinery). The assembly rod 103 ensures the stability and correct working position of the crushing shell 1 during the mechanical movement.

[0045] The straw is fed into the shell through the inlet end of the crushing shell 1. The shape and structure of the circumferential shell are designed to effectively guide the straw into the working area of ​​the crushing roller; the crushing roller built into the shell starts to rotate, and its surface is equipped with cutting blades or crushing teeth, which quickly crush the straw passing through. The crushed straw fragments are further processed or directly used for soil covering; the assembly rod 103 stably connects the crushing shell 1 to the external carrier to ensure that the crushing shell 1 moves synchronously with the movement of the carrier. This stable connection also contributes to the effective transmission of power, because the external carrier usually provides the required power. In addition to closing the shell, the baffle 102 also plays a protective role to ensure safe operation, prevent the escape of fragments or dust during the crushing process, and protect the safety of operators and the environment.

[0046] Specifically, along the traveling direction, all the tilling wheels 3 are located between the two blocking plates 102 .

[0047] In any of the above embodiments, the crushing roller includes a primary transmission shaft 2 and a plurality of first cutters 201 mounted on the primary transmission shaft 2, and the first cutters 201 are used to cut the straw entering the crushing shell 1 through the port.

[0048] In this embodiment, the primary transmission shaft 2 is the main shaft of the crushing roller, which supports and drives all the cutters mounted thereon. This shaft obtains power through the main drive mechanism 5 of the machine (such as an electric motor or an internal combustion engine) and transmits the power to the cutters; a plurality of first cutters 201 are mounted on the primary transmission shaft 2, which are specially designed for cutting straw. Each cutter is usually made of a hard material (such as steel or other wear-resistant materials), has a sharp edge, and can effectively cut straw of different thicknesses and types.

[0049] As the tiller moves along the field, the straw enters the crushing shell 1 through the ports of the crushing shell 1. These ports are located at the front end of the machine and are designed to accommodate and guide the straw directly into the working area of ​​the cutter; the primary drive shaft 2 begins to rotate by activation of the drive mechanism 5. This rotation is directly converted into a cutting action by the first cutter 201 mounted on the shaft. As the shaft rotates, the cutter continuously cuts the incoming straw at high speed, dividing it into small pieces for subsequent processing and mixing with the soil; the cut straw is further processed inside the crushing shell 1 and broken into finer pieces. This process ensures that the straw can be mixed with the soil more easily, while also speeding up the decomposition process of the straw and increasing the organic matter in the soil.

[0050] The straw is effectively cut by high-speed rotating knives, which greatly improves the processing speed and efficiency; the straw cut into small pieces is easier to mix with the soil, increasing the organic matter content of the soil and facilitating the growth of crops; the design allows the type and configuration of the knives to be adjusted to suit different types and conditions of straw, providing a wide range of applications and flexibility.

[0051] In any of the above embodiments, a plurality of second cutters 101 are installed on the inner wall of the crushing shell 1 along the circumference of the primary transmission shaft 2 , and gaps are formed between adjacent second cutters 101 for the first cutter 201 to pass through.

[0052] In this embodiment, the second cutters 101 are mounted on the inner wall of the crushing shell 1 and are evenly distributed along the circumference of the primary transmission shaft 2. These cutters are usually fixed and do not rotate with the shaft, but are designed to interact with the rotating first cutters 201; between adjacent second cutters 101, gaps are formed for the first cutters 201 to pass through. These gaps are precisely calculated to ensure that the first cutters 201 can pass through unhindered when rotating, while interacting closely with the second cutters 101 to achieve effective cutting.

[0053] When the straw enters through the port of the crushing shell 1, it first encounters the rotating first cutters 201. These cutters begin to cut the straw quickly, dividing it into larger segments; the cut straw segments continue to move forward and enter the gap between the first cutter 201 and the second cutter 101. At this stage, the rotating first cutter 201 and the fixed second cutter 101 work together to cut the straw more finely and deeply. This double cutting action ensures that the straw is effectively broken into smaller fragments; the finely cut straw fragments are finally discharged from the outlet of the crushing shell 1 and then mixed with the soil. These small fragments are more easily combined with the soil, accelerating the decomposition of organic matter and improving soil structure.

[0054] Through the cooperation of the first and second cutters 101, the straw crushing efficiency is significantly improved, ensuring the rapid processing of large amounts of straw; smaller straw fragments are conducive to rapid decomposition, increase soil organic matter, improve soil water retention and air permeability, and are beneficial to crop growth; efficient straw processing reduces the energy consumption required for mechanical operations and reduces the impact on the environment.

[0055] In any of the above embodiments, the transmission mechanism 6 includes:

[0056] The first pulley 601 is connected to the driving mechanism 5 .

[0057] The second pulley 602 is fixedly assembled with the primary transmission shaft 2 , and the second pulley 602 is located outside the crushing shell 1 .

[0058] The first belt 603 is sleeved on the first pulley 601 and the second pulley 602 to transmit the torque of the first pulley 601 to the second pulley 602 .

[0059] In this embodiment, the first pulley 601 is directly connected to the driving mechanism 5 (usually an electric motor or an internal combustion engine). The main function of this pulley is to receive the rotational power from the driving mechanism 5 and transmit it to the second pulley 602; the second pulley 602 is fixedly assembled on the primary transmission shaft 2 and is usually located outside the crushing shell 1. The function of this pulley is to receive the torque from the first pulley 601 and convert it into the rotational power of the primary transmission shaft 2; the first belt 603 is a strong transmission belt, which is sleeved on the first and second pulleys 602. Its main function is to transmit torque and power, ensuring that the energy flow from the driving mechanism 5 to the primary transmission shaft 2 is continuous and stable.

[0060] When the driving mechanism 5 is started, it generates rotational power, which is first transmitted to the first pulley 601 directly connected thereto. In this process, the first pulley 601 begins to rotate at a certain speed and force; the rotation of the first pulley 601 is transmitted to the second pulley 602 through the first belt 603. Since the belt is designed to minimize energy loss and maintain the efficiency of the transmission, the power transmission at this stage is efficient and smooth; the second pulley 602 directly converts the received rotational power into the rotation of the primary transmission shaft 2. Since the second pulley 602 is fixedly connected to the primary transmission shaft 2, the crushing roller on the primary transmission shaft 2 immediately begins to rotate and performs its function of crushing the straw.

[0061] Belt drive systems can effectively transmit large amounts of torque and power while reducing energy losses due to factors such as friction; belt drive systems generally have better running smoothness and lower maintenance requirements than gear or direct drive systems; by replacing belts and pulleys of different specifications, the transmission ratio and power output can be adjusted to increase the applicability and flexibility of the machinery.

[0062] In any of the above embodiments, the transmission mechanism 6 further includes a tensioning wheel 604 rotatably mounted on the side wall of the crushing shell 1 , and the side wall of the tensioning wheel 604 is in contact with the outer wall of the first belt 603 .

[0063] In this embodiment, the tension wheel 604 is generally a smaller wheel, which is rotatably mounted on the side wall of the crushing shell 1. Its position and mounting method make its side wall fit with the outer wall of the first belt 603, thereby applying appropriate pressure to the belt.

[0064] The main function of the tensioner 604 is to maintain the proper tension of the transmission belt (first belt 603). During the operation of the machine, the belt may become loose due to temperature changes, wear or long-term use. The tensioner 604 ensures that the belt maintains proper tension by applying constant pressure to the belt to avoid slipping or jumping; during straw crushing and strip tillage operations, the machine will experience varying degrees of vibration and impact. The tensioner 604 can absorb the impact caused by these power changes, protect the belt and transmission system from damage, and extend the service life of the equipment; the position of the tensioner 604 can be fine-tuned as needed, which allows the operator or maintenance personnel to adjust the stroke and tension of the belt. This adjustment function is very important for maintaining the optimal working condition of the transmission system; by maintaining the correct tension of the belt, the tensioner 604 helps improve the efficiency of the entire transmission system. Correct tension can reduce energy loss and ensure smooth transmission of power, thereby improving overall mechanical efficiency.

[0065] By maintaining constant tension, the tensioner 604 ensures stable operation of the transmission system and avoids failures caused by belt slack; reduces mechanical wear caused by vibration or incorrect tension, and helps to extend the life of the belt and related transmission components; the design of the tensioner 604 generally allows quick and easy adjustment, making daily maintenance more convenient.

[0066] In any of the above embodiments, the driving mechanism 5 includes:

[0067] The first driving shaft 501 is connected to the power end of the external carrier; the first driving shaft 501 is rotatably mounted on the outer wall of the crushing shell 1 , and a first bevel gear 503 is fixedly mounted on the first driving shaft 501 .

[0068] One end of the second drive shaft 502 is fixedly connected to the first pulley 601 ; the second drive shaft 502 is rotatably mounted on the outer wall of the crushing shell 1 , and the other end of the second drive shaft 502 is fixedly mounted with a second bevel gear 504 ; the second bevel gear 504 is meshed with the first bevel gear 503 .

[0069] In this embodiment, the first drive shaft 501 is directly connected to the power end on the external vehicle (such as the motor on the tractor). The drive shaft is rotatably mounted on the outer wall of the crushing shell 1, and a first bevel gear 503 is fixedly mounted on the shaft; the first bevel gear 503 located on the first drive shaft 501 is responsible for receiving the rotational power from the first drive shaft 501 and transmitting it to the second bevel gear 504; one end of the second drive shaft 502 is fixedly connected to the first pulley 601, which provides an interface for connecting to the transmission belt system. The second drive shaft 502 is also rotatably mounted on the outer wall of the crushing shell 1, and a second bevel gear 504 is fixedly mounted on the other end; the second bevel gear 504 is mounted on the second drive shaft 502 and meshes with the first bevel gear 503. This configuration allows power to be transmitted from the first drive shaft 501 to the second drive shaft 502 through the bevel gears.

[0070] The power is first transmitted to the first drive shaft 501 through an external carrier. As the first drive shaft 501 rotates, the first bevel gear 503 mounted thereon also starts to rotate; the rotation of the first bevel gear 503 causes the second bevel gear 504 meshing therewith to also start to rotate. The meshing between the bevel gears allows the power to be transferred with high efficiency and accuracy, while allowing a certain angle adjustment to adapt to different installation and operating conditions; after the second drive shaft 502 receives the rotational power through the second bevel gear 504, it transmits this power to the transmission belt system through the first pulley 601. Thus, the power is finally transmitted to the primary transmission shaft 2 and the crushing roller to realize the straw crushing operation.

[0071] The use of bevel gear systems can efficiently transmit power on different axes and adapt to the spatial layout and design requirements of the mechanical structure; bevel gears have high reliability and durability due to their large contact area and high torque transmission efficiency; the design of bevel gears allows a certain deviation in the axial position, which makes the entire transmission system have better adaptability and adjustment space.

[0072] In any of the above embodiments, the driving mechanism 5 further includes a protective cover installed on the outer wall of the crushing shell 1 , and the first bevel gear 503 and the second bevel gear 504 are accommodated inside the protective cover.

[0073] In this embodiment, the protective cover is usually made of a strong material (such as steel plate or heavy plastic) and is designed to accommodate and cover the first and second bevel gears 504. It is mounted on the outer wall of the crushing shell 1, ensuring that all important transmission components are safely enclosed inside.

[0074] The main function of the protective cover is to protect the bevel gears from external physical influences such as collisions, dust, water and other factors that may cause wear or damage. By maintaining the integrity of these critical components, the protective cover helps improve the reliability and durability of the entire drive system; bevel gears may pose a safety risk to operators or nearby objects when in operation. The protective cover effectively prevents accidental contact and reduces safety risks at work by physically isolating these rotating parts; the protective cover design usually takes into account easy maintenance and cleaning. For example, it may be equipped with parts that can be opened or disassembled, allowing operators to easily access internal components when performing routine inspections, maintenance or replacing parts; the protective cover can also reduce the noise and vibration generated by the operation of the bevel gears. The sturdy structure helps absorb and isolate noise, providing a quieter working environment.

[0075] By protecting key transmission components from contamination and physical damage, protective covers extend the service life of equipment; protective covers ensure the safety of operators and prevent accidents that may occur due to contact with rotating parts; protective covers designed to be easy to remove and install make routine maintenance more convenient, reducing downtime and maintenance costs; by reducing noise and vibration, protective covers help create a more comfortable working environment and improve work efficiency.

[0076] In any of the above embodiments, each tillage roller comprises:

[0077] Two corresponding assembly plates 7, at least one assembly plate 7 of a tillage roller is fixedly connected to the side wall of the crushing shell 1; and the assembly plates 7 of adjacent tillage rollers are fixedly assembled.

[0078] The secondary transmission shaft 4 is rotatably mounted on the side wall of the mounting plate 7 ; the tiller wheel 3 is fixedly mounted on the circumferential side wall of the secondary transmission shaft 4 .

[0079] In this embodiment, each tillage roller comprises two corresponding mounting plates 7, which are fixedly connected and fixedly connected to the side walls of the crushing shell 1. The mounting plates 7 provide structural support for the tillage roller and ensure stable installation and operation of the roller; the secondary drive shaft 4 is rotatably mounted on the side walls of the mounting plates 7. This shaft is responsible for supporting and driving the tillage wheel 3 mounted thereon, and is a key part in realizing the tillage function; the tillage wheel 3 is fixedly mounted on the circumferential side walls of the secondary drive shaft 4. The design and layout of the tillage wheel 3 are optimized for specific soil processing requirements and can be of various shapes and sizes to accommodate different tillage depths and soil types.

[0080] The secondary drive shaft 4 is rotatably mounted via a bearing on the mounting plate 7, which ensures its smooth operation during tillage. The transmission system (which may include a belt, chain or gear) transmits power from the main drive mechanism 5 to the secondary drive shaft 4, driving the tillage wheel 3 to rotate; as the secondary drive shaft 4 rotates, the tillage wheel 3 mounted on the shaft begins to work in the soil. The rotation of the tillage wheel 3 cuts, turns or compacts the soil, and can achieve different tillage purposes according to its design, such as deep loosening, leveling or cutting the soil; the mounting plates 7 of adjacent strip tillage rollers are fixedly assembled, which means that they form a group of coordinated tillage units in the direction of travel. This design ensures uniform treatment of the soil throughout the tillage width, avoids treatment gaps, and improves work efficiency and the quality of soil treatment.

[0081] By cultivating the soil evenly and effectively, the soil structure is improved, which helps the development of crop roots and the retention of water and nutrients. Due to the coordinated design of the tillage rollers, a large area of ​​soil can be processed in one process, reducing repetitive work and saving time and resources. By replacing different types of tillage wheels 3, the machine can easily adapt to different soil conditions and tillage needs.

[0082] In any of the above embodiments, a third pulley 8 is rotatably mounted on the side wall of each mounting plate 7 , and the secondary transmission shaft 4 passes through the side wall of the mounting plate 7 and is fixedly connected to the third pulley 8 .

[0083] Along the traveling direction, adjacent third pulleys 8 are commonly sleeved with a second belt 9 .

[0084] In this embodiment, the side wall of each mounting plate 7 is rotatably mounted with a third pulley 8, which is fixedly connected to the secondary transmission shaft 4. The design of the third pulley 8 allows it to carry and transmit power, so that the secondary transmission shaft 4 can drive the tilling wheel 3 to cultivate the soil; the secondary transmission shaft 4 passes through the side wall of the mounting plate 7 and is fixedly connected to the third pulley 8. This fixed connection ensures the synchronous rotation between the pulley and the transmission shaft; along the direction of travel, adjacent third pulleys 8 are connected by a second belt 9. This configuration allows a plurality of continuous tilling rollers to work together and share the power from the upstream drive source.

[0085] When the main drive source (such as a tractor or the main power mechanism on the body) is activated, the power is first transmitted to the first and second drive shafts 502 and their associated pulleys. Subsequently, the power is transmitted to the third pulley 8 on each assembly plate 7 through the second belt 9; since the second belt 9 is connected to a series of third pulleys 8, when any third pulley 8 receives power, the power is transmitted to other adjacent pulleys along the second belt 9. This ensures that the tilling wheels 3 of all the tilling rollers can rotate synchronously, thereby evenly processing the soil; through the synchronous movement of multiple tilling wheels 3, the tiller can perform uniform and effective soil cultivation on a wider travel path. This design avoids the need for work gaps and repeated work, and increases work efficiency.

[0086] The use of a belt and pulley system can effectively transmit power, reduce mechanical complexity and maintenance requirements; since the tilling wheels 3 of the strip roller operate synchronously, the continuity and uniformity of soil treatment can be ensured, and the quality of the crop growth environment can be improved; the continuous power transmission system reduces the impact of a single component failure on the overall operation, and improves the operational reliability and durability of the machinery.

[0087] In any of the above embodiments, a plurality of baffles 10 are rotatably mounted on a port of the crushing shell 1 away from the secondary transmission shaft 4 .

[0088] In this embodiment, the baffle 10 is generally composed of a plurality of solid plates, which are rotatably mounted on one end of the crushing shell 1. The design of the baffle 10 allows them to be rotated or fixed when necessary to adapt to different operating requirements.

[0089] The main function of the baffle 10 is to control the flow and output of the crushed straw. After the straw is processed by the crushing rollers in the crushing shell 1, the baffle 10 helps guide the crushed straw towards a specific output direction to prevent the straw from being scattered randomly and ensure that it is evenly distributed in the farming area; by adjusting the position and angle of the baffle 10, the output and discharge speed of the straw can be accurately controlled. This is critical to ensure the uniformity of soil coverage and the rational use of straw; the baffle 10 also helps prevent the machine from getting blocked during operation. During the crushing process, larger straw blocks may be generated, and the baffle 10 can be adjusted to help export these materials more smoothly and reduce mechanical failures caused by excessive straw accumulation.

[0090] The baffle 10 improves the efficiency of the operation and the quality of soil treatment by controlling the flow direction and distribution of the straw; the adjustability of the baffle 10 allows the machine to adapt to different working conditions and requirements, such as straw treatment of different crops and different soil covering requirements; by reducing blockage and maintaining straw fluidity, the baffle 10 helps maintain the long-term stable operation of the machine and reduce downtime and maintenance costs.

[0091] Working principle:

[0092] The straw enters the machine through the port of the crushing shell 1 and encounters the rotating crushing roller. The crushing roller is equipped with a cutting tool to quickly cut the incoming straw and break it into small pieces; the inner wall of the crushing shell 1 is equipped with a second tool 101, which cooperates with the first tool 201 on the crushing roller to further refine the crushed straw. This step ensures that the straw is effectively cut and prepared for the next step of soil mixing.

[0093] The external carrier provides power, which is transmitted to the first bevel gear 503 through the first drive shaft 501, and then transmitted to the second drive shaft 502 through the meshing second bevel gear 504. This system ensures the stable transmission of mechanical power to various parts of the machine; the first pulley 601 and the second pulley 602 are connected by the first belt 603 to transmit power from the main drive shaft to the secondary drive shaft 4. The tensioner 604 ensures that the belt maintains appropriate tension to maintain transmission efficiency.

[0094] The secondary drive shaft 4 drives the tilling wheel 3 on the tilling roller to rotate and till the soil. The design of the tilling wheel 3 is optimized according to the soil type and crop requirements to achieve the best soil treatment effect; the broken straw is guided by the baffle 10 and evenly distributed on the tilled soil. The adjustable design of the baffle 10 allows the distribution of the straw to be controlled according to the operation requirements to ensure uniform soil coverage.
