Description

A type of diversion land preparation machine Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to a diversion-type land preparation machine. Background Technology

[0002] In agricultural production, land preparation is a crucial step. Existing diversion-type land preparation machines have the following shortcomings. First, the machine is relatively large, which not only consumes more materials and increases manufacturing costs during the manufacturing process, but also causes considerable inconvenience in storage, maintenance, and transportation during the off-season. Second, diversion-type land preparation machines basically do not require the functions of existing harrowing and soil-crushing roller devices when operating in sandy soils, as these devices result in excessive pulling resistance for the land preparation machine. Summary of the Invention

[0003] In order to overcome the lack of equipment redundancy in existing land leveling machines when leveling sandy soil, this application provides a diversion-type land leveling machine, which can achieve the advantages of low pulling resistance and low manufacturing cost.

[0004] To achieve the above objectives, this application adopts the following technical solution: a diversion type land preparation machine, including a frame, a traction frame installed at the front of the frame, a transport wheel installed below the frame, a left folding frame and a right folding frame installed on both sides of the frame, an inward-eighths front inner soil guide diverter and an inward-eighths rear inner soil guide diverter arranged sequentially from front to back below the frame, a diversion scraper forming an outward-eighths front outer soil guide diverter arranged below the left and right folding frames, and a scraper plate assembly that can adjust the scraping depth by gradually tilting downward from front to back below the frame, the left folding frame and the right folding frame, the scraper plate assembly being located behind the rear inner soil guide diverter, and a press roller assembly being located behind the scraper plate assembly.

[0005] The working principle of the above technical solution is as follows: When operating in sandy soil, the sand is evenly distributed by installing a front inner soil guide diverter, a rear inner soil guide diverter, and a front outer soil guide diverter under the frame, left folding frame, and right folding frame. During the diversion process, a certain amount of sand is broken up, which helps with subsequent leveling and compaction operations. After the diversion is completed, the soil is first leveled to a certain depth by the scraper assembly, and then the sand is compacted by the compaction roller assembly. This application has the following advantages: Through reasonable structural design, such as the use of folding frames (left folding frame and right folding frame), compared with the existing diversion type land leveling machine, the overall size of the machine can be reduced during transportation. At the same time, the smaller size also makes storage, maintenance, and transportation more convenient during the off-season. Since sandy soil is mainly composed of large-diameter sand particles with large pores and a loose texture, it is relatively easy to cultivate with less resistance. Therefore, when setting up the soil diverter, one set of rear external soil diverters can be reduced compared to existing technologies, while achieving the same tillage effect. Furthermore, by reducing the equipment used in land leveling, the pulling resistance of the tillage machine can be reduced. The soil scraper assembly, which is inclined downwards from front to back and has an adjustable scraping depth, allows the scraper assembly to level different soil types at different depths, reducing soil compaction. The soil scraper assembly is located between the press roller assembly and the rear internal soil diverter, and together with the press roller assembly, it can effectively level and compact the sand after it has been diverted and dispersed, making the land smoother and improving the quality of land leveling.

[0006] Furthermore, the transport wheel is hinged to the frame via a first hydraulic assembly. The first hydraulic assembly has a first state and a second state. When the first hydraulic assembly is in the first state, the front inner soil guide diverter, the rear inner soil guide diverter, and the press roller assembly are all higher than the transport wheel. When the first hydraulic assembly is in the second state, the front inner soil guide diverter, the rear inner soil guide diverter, and the press roller assembly are all lower than or equal to the transport wheel.

[0007] Using the aforementioned technical solution, when the first hydraulic component is in the first state, the front inner soil guide diverter, the rear inner soil guide diverter, and the press roller assembly are all higher than the transport wheel. At this time, the overall height of the tillage machine is reduced, the center of gravity is more stable, and these working parts will not contact the ground, reducing the risk of wear and damage during transportation, facilitating the transportation and relocation of the tillage machine on the road, and improving its mobility and flexibility.

[0008] Furthermore, the left and right folding frames are hinged to both sides of the frame via a second hydraulic assembly. The second hydraulic assembly has a first state and a second state. When the second hydraulic assembly is in the first state, the left and right folding frames are in an unfolded state flush with the frame. When the second hydraulic assembly is in the second state, the left and right folding frames are in a folded state that is lifted inward.

[0009] Using the aforementioned technical solution, when the left and right folding frames are in the folded state (i.e., the second hydraulic component is in the second state), the lateral dimensions of the tillage machine are significantly reduced. This offers a clear advantage during storage, effectively saving storage space, especially in environments with limited space, greatly improving space utilization. Simultaneously, during transportation, the smaller lateral dimensions better comply with traffic regulations regarding the width of transport equipment, facilitating the transport of the entire machine and reducing transportation difficulty and costs. The unfolded left and right folding frames increase the working width of the tillage machine, enabling it to cover a larger work area. A wider area can be tilled in a single operation, improving work efficiency, reducing the number of round trips, and saving time and fuel resources.

[0010] Furthermore, the inclination angles between the front inner soil guide diverter and the rear inner soil guide diverter and the longitudinal beam extending in the front-rear direction are 45° to 60°, respectively, and the inclination angle between the front outer soil guide diverter and the longitudinal beam extending in the front-rear direction is 30° to 50°.

[0011] Using the aforementioned technical solution, an inclination angle of 45° to 60° allows the front and rear inner soil diverters to evenly distribute the soil to both sides. This angle range ensures sufficient lateral thrust to disperse the soil without excessive splashing or loss, achieving efficient and stable diversion and laying a good foundation for subsequent land preparation operations. An inclination angle of 30° to 50° is suitable for treating soil outside the land preparation machine. The relatively smaller angle allows the front outer soil diverter to avoid excessive soil spillage when diverting soil outwards, better controlling the direction and landing point of the soil, ensuring that the outer soil is evenly distributed within the working area, and preventing soil accumulation or loss at the edges.

[0012] Furthermore, there is a gap between the two inclined beams of the front inner soil guide diverter, and the two inclined beams of the rear inner soil guide diverter are connected to each other.

[0013] By employing the aforementioned technical solution, the gap in the middle of the front inner soil guide diverter allows smaller soil clods or particles to pass through during the diversion process, reducing the possibility of soil accumulation and blockage at the front end of the diverter. This design effectively ensures the normal operation of the diverter, especially when dealing with highly cohesive or moist soils, preventing soil blockage from affecting land preparation efficiency. The interconnected inclined beams form a unified structure, better able to withstand the pressure and impact of soil during diversion. This connection structure is less prone to deformation or damage when encountering larger soil clods or harder soil, ensuring the reliability and service life of the diverter. This design allows for different diversion depths for the front and rear diverters, increasing the leveling effect of sandy soil. For example, the depth of the front inner soil guide diverter can be increased, allowing for coarse leveling due to the gap, while the depth of the rear inner soil guide diverter can be decreased for fine leveling.

[0014] Furthermore, the press roller assembly includes a press roller and a leveling trowel disposed on the rear side of the press roller.

[0015] Using the aforementioned technical solution, the compaction roller can compact the soil after it has been treated by the soil guide diverter, making the soil particles more compact and reducing voids in the soil. During the rolling process, the compaction roller can apply pressure to larger soil clods, breaking them into smaller particles, further improving the soil structure and increasing its aeration and permeability. The leveling trowel, located behind the compaction roller, can further refine and level the compacted surface. It can correct any small bumps, depressions, or unevenness that may occur during the compaction process, achieving a higher degree of flatness on the land surface.

[0016] Furthermore, the leveling slab has a soil guiding surface and a flat soil surface, with the soil guiding surface facing forward and the flat soil surface facing the ground.

[0017] Using the aforementioned technical solution, the guide surface faces forward. As the leveling slab moves forward with the tillage machine, this front section of the guide surface can initially impact and compress larger protrusions or clods on the soil surface, breaking them up or leveling them, thus achieving a pre-leveling effect. The leveling surface facing the ground further compacts and levels the soil, making it finer and more uniform, thereby improving the overall leveling effect and making the land surface more suitable for agricultural production.

[0018] Furthermore, the scraper assembly includes a scraper body, an adjusting component, a hinge component, and a fixing component that is fixed to the frame, the left folding frame, or the right folding frame. The fixing component has fixing holes on its front and rear sides. The hinge component is connected to the fixing hole on the front side of the fixing component and one end of the scraper body, respectively. One end of the adjusting component has an installation hole, and the other end has multiple adjusting holes spaced apart along the extension direction of the adjusting component. The adjusting component is connected to the fixing hole on the rear side of the fixing component through one of the adjusting holes, and is connected to the other end of the scraper body through the installation hole.

[0019] By employing the aforementioned technical solution, the angle of the scraper blade and the depth to which it scrapes the soil can be changed through the connection between the adjustable holes spaced apart on the adjustable component and the fixing holes on the rear side of the fixing component. Since different soil conditions and land preparation requirements necessitate the scraper blade to operate at different angles and depths, this adjustability improves the adaptability of the scraper blade to various working conditions, ensuring the quality of land preparation operations.

[0020] Furthermore, the front inner soil guide diverter consists of two symmetrical diverting scrapers located below the frame; the rear inner soil guide diverter consists of two symmetrical diverting scrapers located below the frame; and the diverting scrapers below the left and right folding frames are symmetrical.

[0021] By adopting the aforementioned technical solutions, the front inner soil guide diverter improves the efficiency and uniformity of land preparation. The two symmetrical scrapers can simultaneously divert large areas of soil, reducing soil accumulation in front of the machine frame, lowering the resistance of the tillage machine, and creating favorable conditions for subsequent operations. The rear inner soil guide diverter enhances the soil preparation effect. Through further diversion and preparation, it can effectively eliminate some unevenness that may be left by the compaction roller, making the land surface smoother and finer, which is conducive to the growth and development of crops. The rear outer soil guide diverter improves the adaptability of the tillage machine to different working widths. Through the design of the folding frame, the position of the diverter can be easily adjusted to meet the needs of farmland operations of different sizes and shapes, reducing the extra manual work for edge areas and improving overall operating efficiency.

[0022] Furthermore, the front inner soil guide diverter of the inner eight and the rear inner soil guide diverter of the inner eight gradually extend away from the frame from front to back, while the front outer soil guide diverter of the outer eight gradually extends towards the frame from front to back.

[0023] Using the aforementioned technical solution, the front and rear inner soil diverters of the inner-eighths-section extend gradually from front to back away from the frame, allowing the soil to gradually diffuse outward during the diversion process. This prevents excessive soil accumulation in front of the frame, ensuring a more even distribution of soil within the working area and improving the soil diversion effect. Simultaneously, the front outer soil diverter extends gradually from front to back towards the frame, complementing the extension direction of the inner soil diverters. This allows the outer soil to flow smoothly inward, merging with the soil diverted by the inner soil diverters, further guaranteeing the uniformity of soil distribution across the entire working area.

[0032] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0033] As shown in Figures 1 to 4, this application provides a diversion type land preparation machine, including a frame 1. A traction frame 11 is installed at the front of the frame 1, and a transport wheel 4 is installed below the frame 1. A left folding frame 2 and a right folding frame 3 are respectively installed on both sides of the frame 1. An inward-pointing front inner soil guide diverter 12 and an inward-pointing rear inner soil guide diverter 13 are arranged sequentially from front to back below the frame 1. A diversion scraper is arranged below the left folding frame 2 and the right folding frame 3 to form an outward-pointing front outer soil guide diverter 21. A scraper assembly 5 that can adjust the scraping depth is arranged below the frame 1, the left folding frame 2, and the right folding frame 3 and gradually tilts downward from front to back. The scraper assembly 5 is located behind the rear inner soil guide diverter 13, and a press roller assembly 14 is arranged behind the scraper assembly 5.

[0034] After adopting the above technical solution, the working principle is as follows: When operating in sandy soil, the sand is evenly divided by installing the front inner soil guide diverter 12, the rear inner soil guide diverter 13, and the front outer soil guide diverter 21 under the frame 1, the left folding frame 2, and the right folding frame 3. During the diversion process, a certain amount of sand is broken up, which helps with subsequent leveling and compaction operations. After the diversion is completed, the soil is first leveled to a certain depth by the scraper assembly 5, and then the sand is compacted by the compaction roller assembly 14. This application has the following advantages: Through reasonable structural design, such as the use of folding frames (left folding frame 2 and right folding frame 3), compared with the existing diversion type land leveling machine, the overall size of the machine can be reduced during transportation. At the same time, the smaller size also makes storage, maintenance, and transportation more convenient during the off-season. Since sandy soil is mainly composed of large-diameter sand particles with large pores and a loose texture, it is relatively easy to cultivate with less resistance. Therefore, when setting up the soil diverter, one set of rear external soil diverters can be reduced compared to the existing technology, while achieving the same tillage effect. Furthermore, by reducing the equipment used in land leveling, the pulling resistance of the tillage machine can be reduced. The soil scraper assembly 5, which is inclined downwards from front to back and has an adjustable scraping depth, allows the soil scraper assembly 5 to level different soils at different depths, reducing soil compaction. The soil scraper assembly 5 is located between the press roller assembly 14 and the rear internal soil diverter 13. Together with the press roller assembly 14, it can effectively level and compact the sand after it has been diverted and dispersed, making the land more level and improving the quality of land leveling. This solution has a simpler structure, resulting in lower manufacturing costs and better practicality and applicability for sandy soils.

[0035] Specifically, the angles between the front inner soil diverter 12, the rear inner soil diverter 13, and the front outer soil diverter 21 and the longitudinal beam 8 extending in the front-rear direction can be adjusted according to the working conditions. For example, when performing shallow tillage operations, the soil is turned over at a shallow depth. To ensure that the soil can be fully diverted without being over-scattered, the angle between each soil diverter and the longitudinal beam 8 can be between 35° and 50°. A smaller angle allows the soil to be evenly dispersed in the shallow layer, preventing the soil from being thrown too high or too far due to an excessively large angle, thus affecting the tillage effect. For deep tillage operations, it is necessary to turn over the deep soil and divert it. In this case, to ensure that the deep soil can be smoothly lifted and diverted to both sides, the angle between the soil diverter and the longitudinal beam 8 can be adjusted to 50°-65°. A larger angle can provide greater lifting force and lateral force, ensuring that the deep soil can be effectively dispersed and distributed on the working surface.

[0036] Furthermore, the transport wheel 4 is hinged to the frame 1 via a first hydraulic assembly 6. The first hydraulic assembly 6 has a first state and a second state. When the first hydraulic assembly 6 is in the first state, the front inner soil guide diverter 12, the rear inner soil guide diverter 13, and the press roller assembly 14 are all higher than the transport wheel 4. When the first hydraulic assembly 6 is in the second state, the front inner soil guide diverter 12, the rear inner soil guide diverter 13, and the press roller assembly 14 are all lower than or equal to the transport wheel 4.

[0037] Using the aforementioned technical solution, when the first hydraulic component 6 is in the first state, the front inner soil guide diverter 12, the rear inner soil guide diverter 13, and the press roller assembly 14 are all higher than the transport wheel 4. At this time, the overall height of the tillage machine is reduced, the center of gravity is more stable, and these working parts will not contact the ground, reducing the risk of wear and damage during transportation, facilitating the transportation and relocation of the tillage machine on the road, and improving its mobility and flexibility.

[0038] Specifically, the height comparison method described above involves comparing the lowest point of the front inner soil guide diverter 12, the rear inner soil guide diverter 13, and the press roller assembly 14 with the lowest point of the transport wheel 4. The first hydraulic assembly 6 is fixed to the frame 1 by one end of a hydraulic cylinder, and the end of the telescopic rod on the hydraulic cylinder is fixed to the wheel frame of the transport wheel. The first hydraulic assembly 6 switches between a first state and a second state by extending and retracting the telescopic rod of the hydraulic cylinder, thereby changing the relative height of the front inner soil guide diverter 12, the rear inner soil guide diverter 13, and the press roller assembly 14 with the transport wheel 4.

[0039] Furthermore, the left folding frame 2 and the right folding frame 3 are hinged to both sides of the frame 1 by the second hydraulic assembly 7. The second hydraulic assembly 7 has a first state and a second state. When the second hydraulic assembly 7 is in the first state, the left folding frame 2 and the right folding frame 3 are in an unfolded state flush with the frame 1. When the second hydraulic assembly 7 is in the second state, the left folding frame 2 and the right folding frame 3 are in a folded state that is lifted inward.

[0040] Using the aforementioned technical solution, when the left folding frame 2 and right folding frame 3 are in the folded state (i.e., the second hydraulic component 7 is in the second state), the lateral dimensions of the tillage machine are significantly reduced. This offers a clear advantage during storage, effectively saving storage space, especially in storage environments with limited space, greatly improving space utilization. Simultaneously, during transportation, the smaller lateral dimensions better comply with traffic regulations regarding the width of transport equipment, facilitating the transport of the entire machine and reducing transportation difficulty and costs. The unfolded left folding frame 2 and right folding frame 3 increase the working width of the tillage machine, enabling it to cover a larger working area. A wider area can be tilled in a single operation, improving work efficiency, reducing the number of round trips, and saving time and fuel resources.

[0041] Specifically, the second hydraulic assembly 7 is fixed to the frame 1 at one end via a hydraulic cylinder, and the end of the telescopic rod on the hydraulic cylinder is fixed to the left folding frame 2. The telescopic rod of the hydraulic cylinder extends and retracts to switch the second hydraulic assembly 7 to the first state and the second state, thereby changing the folding state and unfolding state of the left folding frame 2. The second hydraulic assembly 7 is fixed to the frame 1 at one end via a hydraulic cylinder, and the end of the telescopic rod on the hydraulic cylinder is fixed to the right folding frame 3. The telescopic rod of the hydraulic cylinder extends and retracts to switch the second hydraulic assembly 7 to the first state and the second state, thereby changing the folding state and unfolding state of the right folding frame 3. During the folding process of the left folding frame 2 and the right folding frame 3, the scraper assembly 5 and the press roller assembly 14 on them will fold upward together.

[0042] Furthermore, the front inner soil guide diverter 12 and the rear inner soil guide diverter 13 are inclined at angles of 45° to 60° to the longitudinal beam 8 extending in the front-rear direction, respectively, and the front outer soil guide diverter 21 is inclined at angles of 30° to 50° to the longitudinal beam 8 extending in the front-rear direction.

[0043] Using the aforementioned technical solution, an inclination angle of 45° to 60° allows the front inner soil guide diverter 12 and the rear inner soil guide diverter 13 to evenly distribute the soil to both sides. This angle range ensures sufficient lateral thrust to disperse the soil without causing excessive splashing or loss, thus achieving an efficient and stable diversion effect and laying a good foundation for subsequent land preparation operations. An inclination angle of 30° to 50° is suitable for processing the soil outside the land preparation machine. The relatively small angle allows the front outer soil guide diverter 21 to avoid excessive soil spillage when diverting the soil outward, better controlling the direction and landing point of the soil, ensuring that the outer soil is evenly distributed within the working area, and preventing the accumulation or loss of soil at the edges.

[0044] Preferably, the front inner soil guide diverter 12 and the rear inner soil guide diverter 13 are inclined at an angle of 50° to the longitudinal beam 8 extending in the front-rear direction, and the front outer soil guide diverter 21 is inclined at an angle of 45° to the longitudinal beam 8 extending in the front-rear direction.

[0045] Using the aforementioned technical solution, the 50° angle of the inner soil diverter allows the soil to receive a moderate lateral force during diversion, ensuring effective soil dispersion and even distribution within the work area, preventing soil concentration in any one area. The 45° angle of the outer soil diverter complements the inner soil diverter, ensuring that the diversion effect on the outer side matches that on the inner side, further improving the uniformity of soil distribution across the entire work area and creating favorable conditions for subsequent compaction and other operations.

[0046] Specifically, the aforementioned front inner soil guide diverter 12 and rear inner soil guide diverter 13 are inclined at angles of ∠α with the longitudinal beam 8 extending in the front-rear direction, as shown in Figure 3; the front outer soil guide diverter 21 is inclined at angles of ∠β with the longitudinal beam 8 extending in the front-rear direction, as shown in Figure 3.

[0047] Furthermore, there is a gap between the two inclined beams of the front inner soil diverter 12, and the two inclined beams of the rear inner soil diverter 13 are connected to each other.

[0048] By employing the aforementioned technical solution, the gap in the middle of the front inner soil guide diverter 12 allows some smaller soil clods or particles to pass through during the soil diversion process, reducing the possibility of soil accumulation and blockage at the front end of the diverter. Especially when dealing with highly viscous or moist soils, this design effectively ensures the normal operation of the diverter and avoids affecting land preparation efficiency due to soil blockage. The interconnected inclined beams form a unified structure, better able to withstand the pressure and impact of the soil during diversion. When encountering larger soil clods or harder soil, this connection structure is less prone to deformation or damage, ensuring the reliability and service life of the diverter. This design allows for different types of soil guiding depths in the front and rear diverters, increasing the effect of sand diversion and leveling. For example, the depth of the front inner soil guide diverter 12 can be increased, allowing for coarse leveling due to the gap, while the depth of the rear inner soil guide diverter 13 can be decreased for fine leveling. Specifically, the aforementioned inclined beams are used to fix the corresponding soil guide diverters, ensuring that the corresponding soil guide diverters are both interconnected and spaced apart.

[0049] Furthermore, the press roller assembly 14 includes a press roller and a leveling trowel 15 disposed on the rear side of the press roller.

[0050] Using the aforementioned technical solution, the compaction roller can compact the soil after it has been treated by the soil guide diverter, making the soil particles more compact and reducing voids in the soil. During the rolling process, the compaction roller can apply pressure to larger soil clods, breaking them into smaller particles, further improving the soil structure and increasing soil aeration and permeability. The leveling trowel 15, located behind the compaction roller, can further refine and level the compacted ground. It can correct small bumps, depressions, or unevenness that may occur during the compaction process, achieving a higher degree of flatness on the land surface.

[0051] Furthermore, the leveling slab 15 is provided with a soil guiding surface 151 and a flat soil surface 152, with the soil guiding surface 151 facing the front and the flat soil surface 152 facing the ground.

[0052] Using the aforementioned technical solution, the guide surface 151 faces forward. As the leveling slab 15 moves forward with the tillage machine, this part of the guide surface 151 can initially impact and compress some larger protrusions or clods on the soil surface, breaking them or leveling them, thus playing a pre-leveling role. The leveling surface 152 facing the ground can further compact and level the soil surface, making the soil finer and more uniform, thereby improving the overall leveling effect and making the land surface more suitable for agricultural production.

[0053] Furthermore, the scraper assembly 5 includes a scraper body 51, an adjusting member 52, a hinge member 53, and a fixing member 54 fixed to the frame 1, the left folding frame 2, or the right folding frame 3. The fixing member 54 has fixing holes on its front and rear sides. The hinge member 53 is connected to the fixing holes on the front side of the fixing member 54 and fixed to one end of the scraper body 51. The adjusting member 52 has an installation hole on one end and multiple adjusting holes spaced apart along the extension direction of the adjusting member 52 on the other end. The adjusting member 52 is connected to the fixing hole on the rear side of the fixing member 54 through one of the adjusting holes and connected to the other end of the scraper body 51 through the installation holes.

[0054] Using the aforementioned technical solution, the scraper body 51 in the scraper assembly 5 is connected to the fixing hole on the rear side of the fixing member 54 through one of the adjusting holes spaced apart on the adjusting member 52. This allows the height of both ends of the scraper body 51 to be changed, thereby altering the angle of the scraper body 51 and the depth to which the scraper body 51 scrapes the soil. Since different soil conditions and land preparation requirements necessitate the scraper body to operate at different angles and depths, this adjustability improves the adaptability of the scraper body to various working conditions, ensuring the quality of land preparation operations. Specifically, when the scraper assembly 5 is located below the frame 1, the fixing member 54 is fixed to the vertical beam extending downward from the frame 1, and the fixing member 54 extends in the front-back direction and is horizontally mounted on the vertical beam. The fixing holes on the fixing member 54 are located at both ends of the fixing member 54. The fixing member 54 has multiple fixing members, which are spaced apart in the left-right direction so that it can be used to install the hinge member 53 and the adjusting member 52. The fixing holes on the fixing member 54 are connected to the hinge plate 53 and the adjusting member 52 by hinge. The adjusting member 52 is connected to the scraper body 51 by hinge. The hinge connection mentioned above can be made by bolts or other means.

[0055] Furthermore, the front inner soil guide diverter 12 consists of two symmetrical diverting scrapers arranged below the frame 1; the rear inner soil guide diverter 13 consists of two symmetrical diverting scrapers arranged below the frame 1; and the diverting scrapers below the left folding frame 2 and the right folding frame 3 are symmetrical.

[0056] By adopting the aforementioned technical solutions, the front inner soil diverter 12 improves the efficiency and uniformity of land preparation. The two symmetrical scrapers can simultaneously divert a large area of ​​soil, reducing soil accumulation in front of the frame 1, lowering the resistance of the tillage machine, and creating favorable conditions for subsequent operations. The rear inner soil diverter 13 enhances the soil preparation effect. Through further diversion and preparation, it can effectively eliminate some unevenness that may be left by the press roller, making the land surface smoother and finer, which is conducive to the growth and development of crops. The rear outer soil diverter improves the adaptability of the tillage machine to different working widths. Through the design of the folding frame, the position of the diverter can be easily adjusted to meet the needs of farmland operations of different sizes and shapes, reduce the extra manual processing work on the edge areas, and improve the overall operating efficiency.

[0057] Furthermore, the front inner soil guide diverter 12 and the rear inner soil guide diverter 13 of the inner eight extend gradually from front to back away from the frame 1, while the front outer soil guide diverter 21 of the outer eight extends gradually from front to back towards the frame 1.

[0058] Using the aforementioned technical solution, the front inner soil diverter 12 and the rear inner soil diverter 13 extend gradually from front to back away from the frame 1, allowing the soil to gradually diffuse outward during the diversion process. This prevents excessive soil accumulation in front of the frame, ensuring a more even distribution of soil within the working area and improving the soil diversion effect. Simultaneously, the front outer soil diverter 21 extends gradually from front to back towards the frame 1, coordinating with the extension direction of the front inner soil diverter 12. This allows the outer soil to flow smoothly inward, merging with the soil diverted by the inner soil diverter, further ensuring the uniformity of soil distribution throughout the entire working area.

[0059] In addition to the preferred embodiments described above, this application has other implementation methods. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection claimed in this application.
