Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a soil scraping depth adjustment device for a diversion type land tillage machine and the diversion type land tillage machine. Background Technology

[0002] With the continuous development of agricultural machinery, diversion-type land preparation machines have been widely promoted and applied in agricultural production. They can break up and reorganize land, helping to improve soil fertility, soil structure, and agricultural production efficiency, and creating a favorable soil environment for crop growth. Diversion-type land preparation machines include a soil-breaking module, a soil-guiding module, and a soil-forming module. For example, Chinese patent CN117461409A discloses a diversion-type land preparation machine leveling plate depth adjustment device and a diversion-type land preparation machine. The device includes a leveling plate depth adjustment device comprising a leveling plate fixing beam, a rotating hinge, a leveling plate, a screw lug, and an adjusting screw. One end of the adjusting screw is connected to the leveling plate fixing beam, and the other end is rotatably connected to the leveling plate via the screw lug. One end of the rotating hinge is connected to the lower part of the leveling plate fixing beam, and the other end is rotatably connected to the leveling plate. The leveling plate depth is adjusted by adjusting the connection position between the adjusting screw and the leveling plate fixing beam. In the above-mentioned leveling plate depth adjustment device, the adjusting screw is locked by a locking nut. During operation, the locking nut will loosen due to the frequent impact of soil and rock fragments on the leveling plate, causing the leveling plate depth adjustment function to fail and the stability to be poor. In addition, the leveling plate lacks flexibility and its application scenarios are limited. Utility Model Content

[0003] To address the technical problems of poor stability and insufficient flexibility of the aforementioned leveling plate depth adjustment device, this utility model provides a diversion type land leveling machine scraping depth adjustment device and a diversion type land leveling machine. The depth adjustment function has good stability and is not prone to failure. The scraping plate can be adjusted in height, angle, and front-back position.

[0004] The specific technical solution of this utility model is as follows: a soil scraping depth adjustment device for a diversion-type land preparation machine, comprising a fixed beam, an adjusting component, and a scraping blade. The fixed beam has a first connecting part on its rear side and a second connecting part on its front side. One end of the adjusting component is hinged to the scraping blade, and the end of the scraping blade away from the adjusting component has a connecting component. The connecting component is located on a surface close to the fixed beam. The second connecting part is hinged to the connecting component. An adjustment space is formed between the scraping blade and the fixed beam, and the scraping blade forms an acute angle with the ground. The adjusting component has a plurality of third connecting parts, and the plurality of third connecting parts are matched with the first connecting parts and selectively hinged to the first connecting parts through a hinge structure. Alternatively, the first connecting part has a plurality of third connecting parts, and the plurality of third connecting parts are matched with the adjusting component and selectively hinged to the adjusting component through a hinge structure.

[0005] The aforementioned scraper blade is connected to the fixed beam via a first connecting part and a second connecting part. One end of the adjusting member is hinged to the first connecting part, and the other end is hinged to the scraper blade. The end of the scraper blade away from the adjusting member is hinged to the second connecting part via a connecting member. The adjusting member and the connecting member create an adjustment space between the scraper blade and the fixed beam. The length of the connecting member is fixed and not zero, ensuring a certain gap between the scraper blade and the fixed beam. This allows the scraper blade to have freedom in both the height and front-back directions. The height of the scraper blade is adjusted through the connection between the adjusting member and the first connecting part. The front-back position of the scraper blade is adjusted by rotating the adjusting member and the connecting member in the front-back direction, thus adjusting the depth of the scraper blade. The angle of the scraper blade is adjusted through two hinge points on the scraper blade, thereby preventing soil accumulation. The scraper blade has a large adjustable range, high flexibility, and a wide range of applications. The device has several third connecting parts, i.e., multiple height adjustment points, making adjustment convenient and accurate. The fixed beam, adjusting member, and scraper blade are connected by hinges, ensuring a stable connection that will not loosen due to impact from soil and rock fragments, thus improving the stability of the device.

[0006] Preferably, the third connecting part is an adjustment hole, and a plurality of adjustment holes are spaced apart along the length direction of the adjusting member. The first connecting part is detachably connected to a first hinge shaft, and one of the first hinge shafts passes through the adjustment hole; or, a plurality of adjustment holes are spaced apart along the length direction of the first connecting part, and a first hinge shaft is detachably connected to the adjusting member, and one of the first hinge shafts passes through the adjustment hole.

[0007] In the above technical solution, the height of the scraper blade can be precisely adjusted by inserting the first hinge shaft into different adjustment holes. The adjustment holes have strong limiting capabilities, preventing the scraper blade from shifting or deviating. The first hinge shaft is easy to install and remove, and this adjustment method is simple to operate and can efficiently and stably adjust the scraper blade to the required height.

[0008] Preferably, one end of the first hinge shaft is provided with a limiting shoulder, and the other end is detachably connected to a limiting member, with the adjustment hole located between the limiting shoulder and the limiting member.

[0009] In the above technical solution, under the combined action of the limiting shoulder and the limiting component, the position of the first hinge shaft in the adjusting hole is stable, effectively preventing the first hinge shaft from shifting or shaking during operation, which would affect the operation of the scraper blade. This structure improves the stability and reliability of the device.

[0010] Preferably, the scraper is a flat plate; or, the scraper is an arc plate that protrudes in the direction away from the fixed beam.

[0011] In the above technical solution, the scraper blade is a flat plate or an arc plate, which is simple to process and easy to manufacture. This structure makes the scraper blade bear force evenly and distribute stress during operation, thus improving the durability of the scraper blade.

[0012] Another specific technical solution of this utility model is: a diversion type land preparation machine, including a traction frame and a frame body. The traction frame is arranged in front of the frame body. From front to back, the frame body is provided with a soil-crushing rake group, a transport wheel, a soil-crushing and pressing roller group and a trowel. It also includes the above-mentioned soil scraping depth adjustment device, which is arranged below the frame body and between the transport wheel and the soil-crushing and pressing roller group.

[0013] Preferably, at least two outward-facing inclined beam soil guides and at least two inward-facing inclined beam soil guides are provided below the frame body. The outward-facing inclined beam soil guides are located behind the soil-crushing rake assembly, and the inward-facing inclined beam soil guides are located behind the outward-facing inclined beam soil guides. The soil outlet end of the outward-facing inclined beam soil guide and the soil inlet end of the inward-facing inclined beam soil guide at least partially overlap in the width direction.

[0014] In the above technical solution, multiple outward-facing inclined beam soil guides are used to collect and crush large soil clods remaining from the soil-crushing rake group at higher elevations. The crushed large soil clods then enter the inward-facing inclined beam soil guides through the outlet end of the outward-facing inclined beam soil guides. Multiple inward-facing inclined beam soil guides further break up the soil clods and distribute the soil in various directions, solving the problem of uneven soil surfaces and pits, thus achieving effective land leveling. While there is a tendency or path for the inward-facing and outward-facing inclined beam soil guides to intersect, they do not actually overlap at any point, and a gap always exists between them. By setting up multiple outward-facing and inward-facing inclined beam soil guides in a crisscrossing distribution, the complex soil flow path more effectively breaks up and disperses soil clods, resulting in more soil diversions and better land leveling efficiency.

[0015] Preferably, the outward-facing inclined beam soil guide includes a first outward-facing inclined beam soil guide and a second outward-facing inclined beam soil guide. The soil entry ends of the first outward-facing inclined beam soil guide and the second outward-facing inclined beam soil guide are aligned in the front-to-back direction. The second outward-facing inclined beam soil guide is located in the middle of the first outward-facing inclined beam soil guide and is spaced apart from the first outward-facing inclined beam soil guide.

[0016] In the above technical solution, the second outer V-shaped inclined beam soil guide is located in the middle of the first outer V-shaped inclined beam soil guide, that is, the second outer V-shaped inclined beam soil guide is closer to the central axis of the frame body. This structure improves the soil collection efficiency, so that the soil blocks can be guided more smoothly and more concentratedly to the inner V-shaped inclined beam soil guide, thereby making the soil blocks more efficiently broken by the inner V-shaped inclined beam soil guide.

[0017] Preferably, the soil exit end of the second outward-facing inclined beam soil guide is located in front of the soil exit end of the first outward-facing inclined beam soil guide.

[0018] In the above technical solution, the soil outlet end of the second outward-facing inclined beam soil guide is located in front of the soil outlet end of the first outward-facing inclined beam soil guide, so that the soil outlet end of the second outward-facing inclined beam soil guide has sufficient spacing, preventing soil clods from accumulating at the soil outlet end of the second outward-facing inclined beam soil guide, and further improving the efficiency of soil clod treatment.

[0019] Preferably, the inward-facing inclined beam soil guide includes a first inward-facing inclined beam soil guide and a second inward-facing inclined beam soil guide, wherein the first inward-facing inclined beam soil guide and the second inward-facing inclined beam soil guide are offset in the front-back direction.

[0020] In the above technical solution, the staggered setting means that the first inward-facing inclined beam soil guide and the second inward-facing inclined beam soil guide can partially overlap but not overlap in the front-to-back direction, which extends the path of soil crushing and diversion, realizes multi-stage crushing and diversion, improves the efficiency of soil processing, and makes the land leveling effect better.

[0021] Preferably, the soil entry end of the first inward-facing inclined beam soil guide is located at the front end of the soil entry end of the second inward-facing inclined beam soil guide, the soil entry end of the first inward-facing inclined beam soil guide is open, and the soil entry end of the second inward-facing inclined beam soil guide is closed.

[0022] In the above technical solution, the soil entry end of the first inward-facing inclined beam soil guide is open, which helps to disperse the soil to a wider area, while the soil entry end of the second inward-facing inclined beam soil guide is closed, which enhances the crushing efficiency and further improves the efficiency of soil block processing.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] (1) The soil scraping depth adjustment device has good stability and high flexibility: the fixed beam, the adjusting component and the scraping plate are connected by hinges, which is not easy to loosen and has high stability. The adjusting component and the connecting component make the scraping plate and the fixed beam form an adjustment space. The length of the connecting component is fixed and not zero, so there is a certain gap between the scraping plate and the fixed beam. The height, front and back position and angle can be adjusted to achieve the purpose of adjusting the depth.

[0025] (2) The diversion type land leveling machine has a good land leveling effect: It adopts multiple outward-facing inclined beam soil guides and multiple inward-facing inclined beam soil guides to optimize the efficiency of soil collection, crushing and dispersion. The outward-facing and inward-facing inclined beam soil guides are distributed in a cross pattern. The soil outlet end of the outward-facing inclined beam soil guide and the soil inlet end of the inward-facing inclined beam soil guide at least partially overlap in the width direction. The inward-facing inclined beam soil guides are staggered in the front-back direction, creating a complex soil flow path, which more effectively crushes and disperses soil clods. The soil is diverted multiple times, resulting in a good land leveling effect. Attached Figure Description

[0032] The present invention will be further described below with reference to embodiments. Unless otherwise specified, all devices, connection structures, and methods involved in this invention are known in the art.

[0033] Example 1

[0034] Reference Figures 3 to 5As shown, this utility model provides a soil scraping depth adjustment device for a diversion type land leveling machine, including a fixed beam 11, an adjusting component 14, and a scraping blade 15. The fixed beam 11 is fixedly connected to the frame body 2 of the diversion type land leveling machine by means of U-shaped clips or screws. The fixed beam 11 has a first connecting part 12 on the rear side and a second connecting part 13 on the front side. One end of the adjusting component 14 is hinged to the first connecting part 12, and the other end is hinged to the scraping blade 15. The scraping blade 15 has a connecting component 151 at the end away from the adjusting component 14. The connecting component 151 is located on the side close to the fixed beam 11 and faces the fixed beam 11. The second connecting part 13 is hinged to the connecting component 151. The length of the adjusting component 14 is greater than that of the connecting component 151. An adjustment space 10 is formed between the scraping blade 15 and the fixed beam 11. The scraping blade 15 forms an acute angle with the ground. The adjusting member 14 is provided with a plurality of third connecting parts 16, each of which matches the first connecting part 12. One of the third connecting parts 16 is selectively hinged to the first connecting part 12 via a hinge structure to adjust the height of the scraper blade 15. It can be understood that in another embodiment, the first connecting part 12 is provided with a plurality of third connecting parts 16, each of which matches the adjusting member 14. One of the third connecting parts 16 is selectively hinged to the adjusting member 14 via a hinge structure to adjust the height of the scraper blade 15.

[0035] The adjusting member 14 and connecting member 151 of this device create an adjustment space 10 between the scraper blade 15 and the fixed beam 11. The length of the adjusting member 14 is greater than that of the connecting member 151, and the length of the connecting member 151 is fixed and not zero, resulting in a certain gap between the scraper blade 15 and the fixed beam 11. This allows the scraper blade 15 to have degrees of freedom in both the height and front-back directions. The height of the scraper blade 15 is adjusted through the connection between the adjusting member 14 and the first connecting part 12. The front-back position of the scraper blade 15 is adjusted by rotating the adjusting member 14 and the connecting member 151 in the front-back direction, thereby adjusting the depth of the scraper blade 15. The angle of the scraper blade 15 is adjusted through two hinge points on the scraper blade 15, thus preventing soil accumulation. This device has several third connecting parts 16, i.e., multiple height adjustment points, making adjustment convenient and accurate. The fixed beam 11, adjusting member 14, and scraper blade 15 are connected by hinges, ensuring a stable connection that will not loosen due to impact from soil and rock fragments, thus improving the stability of the device. In the figure, the Z direction represents the length direction.

[0036] The implementation of this device is as follows: The depth of the scraper blade 15 during operation is determined based on soil type, hardness, and moisture. A third connecting part 16 matching this depth is selected on the adjusting member 14 and hinged to the first connecting part 12. Then, according to operational needs, the adjusting member 14 and the connecting part 151 are rotated in the front-back direction to adjust the front-back position of the scraper blade 15, thus completing the scraping depth adjustment. The scraping angle of the scraper blade 15 is adjusted through the two hinge points on the scraper blade 15 to prevent soil accumulation. It can be understood that in another embodiment, the depth of the scraper blade 15 during operation is determined based on soil type, hardness, and moisture. A third connecting part 16 matching this depth is selected on the first connecting part 12 and hinged to the adjusting member 14. Then, according to operational needs, the front-back position and angle of the scraper blade 15 are adjusted.

One end of the first hinge shaft 17, the second hinge shaft 18, and the third hinge shaft 19 is provided with a limiting shoulder, and the other end is detachably connected to a limiting member 8. The limiting member 8 passes through the hinge shaft along its length, and its length is greater than the diameter of the hole at that end of the hinge shaft. The adjusting hole is located between the limiting shoulder of the first connecting shaft and the limiting member 8. The scraper blade 15 is flat.

[0039] In this embodiment, the height of the scraper blade 15 is precisely adjusted by inserting the first hinge shaft 17 into different adjustment holes. The adjustment holes have strong limiting capabilities, preventing the scraper blade 15 from shifting or deviating. The first hinge shaft 17 is easy to install and remove. This adjustment method is simple to operate and can efficiently and stably adjust the scraper blade 15 to the required height. Under the combined action of the limiting shoulder and the limiting member 8, the position of the first hinge shaft 17 in the adjustment hole is stable, effectively preventing the first hinge shaft 17 from shifting or shaking during operation, which would affect the operation of the scraper blade 15 and improve the stability and reliability of the device. The scraper blade 15 is a flat plate, which is simple to manufacture and easy to process. The scraper blade 15 is subjected to uniform force during operation, improving the durability of the scraper blade 15.

[0040] The implementation method of this device is as follows: the depth of the scraper blade 15 during operation is determined according to the soil type, hardness and moisture, an adjustment hole matching the depth is selected on the adjustment member 14, the first hinge shaft 17 is inserted into the adjustment hole, the limiting member 8 is inserted into the first hinge shaft 17, the limiting shoulder and the limiting member 8 limit the first hinge shaft 17, so that the first connecting part 12 is hinged with the adjustment member 14, and then the adjustment member 14 and the connecting member 151 are rotated in the front and back direction according to the operation needs to adjust the front and back position of the scraper blade 15 and complete the scraping depth adjustment. The scraping angle of the scraper blade 15 is adjusted by the rotating hinge 152 on the scraper blade 15 and the hinge point between the connecting member 151 and the second connecting part 13 to prevent soil clogging.

[0041] Example 3

[0042] Based on Example 1, such as Figures 3 to 5As shown, this utility model provides a soil scraping depth adjustment device for a diversion-type land preparation machine.

Each end of the first hinge shaft 17, the second hinge shaft 18, and the third hinge shaft 19 is provided with a limiting member 8. The limiting member 8 passes through the hinge shaft along its length, and its length is greater than the diameter of the hole at that end of the hinge shaft. The adjustment hole is located between the limiting shoulder of the first connecting shaft and the limiting member 8. The scraper blade 15 is an arc-shaped plate that protrudes away from the fixed beam 11.

[0043] In this embodiment, the height of the scraper blade 15 is precisely adjusted by inserting the first hinge shaft 17 into different adjustment holes. The adjustment holes have strong limiting capabilities, preventing the scraper blade 15 from shifting or deviating. The first hinge shaft 17 is easy to install and remove. This adjustment method is simple to operate and can efficiently and stably adjust the scraper blade 15 to the required height. Under the combined action of the limiting shoulder and the limiting member 8, the position of the first hinge shaft 17 in the adjustment hole is stable, effectively preventing the first hinge shaft 17 from shifting or shaking during operation, which would affect the operation of the scraper blade 15 and improve the stability and reliability of the device. The scraper blade 15 is an arc plate, which is simple to process and easy to manufacture.

[0045] Example 4

[0046] Reference Figures 1 to 5 As shown, this utility model provides a diversion type land preparation machine, including a traction frame 3, a frame body 2, a soil-crushing rake assembly 4, a transport wheel 5, a soil-crushing and pressing roller assembly 6, and a trowel 7. The traction frame 3 is located in front of the frame body 2. The soil-crushing rake assembly 4, the transport wheel 5, the soil-crushing and pressing roller assembly 6, and the trowel 7 are arranged sequentially from front to back below the frame body 2. The soil-scraping depth adjustment device 1 described in Embodiment 1 is also provided below the frame body 2. The soil-scraping depth adjustment device 1 is located below the frame body 2 and between the transport wheel 5 and the soil-crushing and pressing roller assembly 6. The frame body 2 includes a left folding frame 26, a right folding frame 25, and a main frame 27. The left folding frame 26 and the right folding frame 25 are located on both sides of the main frame 27 and are hinged to the main frame 27 respectively. The frame body 2 is equipped with a folding hydraulic cylinder 91 to realize the upward lifting and downward lowering of the left folding frame 26 and the right folding frame 25. A crossbeam is provided below the frame body 2, and the soil crushing rake assembly 4 is fixed to the crossbeam by a U-shaped clip. The vertical depth of the soil crushing rake assembly 4 is adjustable, and the front and rear angle is adjustable. The frame body 2 is equipped with a hydraulic cylinder for the transport wheels 5 to realize the raising and lowering of the transport wheels 5.

[0047] At least two outward-facing inclined beam soil guides and at least two inward-facing inclined beam soil guides are provided below the frame body 2. The outward-facing inclined beam soil guides are located behind the soil-crushing rake group 4, and the inward-facing inclined beam soil guides are located behind the outward-facing inclined beam soil guides. The inward-facing and outward-facing inclined beam soil guides are distributed in a crisscross pattern without actual overlap. The soil exit end of the outward-facing inclined beam soil guide and the soil entry end of the inward-facing inclined beam soil guide at least partially overlap in the width direction. In the figure, the X direction is from back to front, the Y direction is the width direction, and the Z direction is the height direction.

[0048] In this embodiment, multiple outward-facing inclined beam soil guides are used to collect and crush excess soil clods remaining from the crushing of the soil by the soil-crushing rake group 4. The crushed soil clods then enter the inward-facing inclined beam soil guides through the outlet end of the outward-facing inclined beam soil guides. The multiple inward-facing inclined beam soil guides further break up the soil clods and distribute the soil in various directions, solving the problem of uneven soil surfaces and pits, thus achieving effective land leveling. The inward-facing and outward-facing inclined beam soil guides are distributed in a crisscross pattern, meaning there is a tendency or path of intersection between them, but there is no actual overlap at any point; a gap always exists between them. By setting multiple outward-facing and inward-facing inclined beam soil guides in a crisscross pattern, a complex soil flow path is created, which more effectively breaks up and disperses soil clods, resulting in more soil diversions and better land leveling.

[0049] The implementation method of this device is as follows: When the diversion type land leveling machine arrives at the work site, the scraper blade 15 is adjusted to a suitable height, the folding hydraulic cylinder 91 controls the left folding frame 26 and the right folding frame 25 to be lowered, the transport wheel 5 hydraulic cylinder controls the transport wheel 5 to be retracted, the traction frame 3 pulls the diversion type land leveling machine forward, the soil crushing rake group 4 breaks the ground into soil clods, some soil clods are crushed by the left folding frame 26, the right folding frame 25 and the main frame 27, and some enter the outer V-shaped inclined beam soil guide for crushing. The crushed soil clods enter the inner V-shaped inclined beam soil guide for crushing and diversion, and are then impacted and leveled by the scraper blade 15 to make the soil evenly distributed. Then, the soil is compacted and leveled by the soil crushing and pressing roller group 6 and the trowel 7 to make the land flat and complete the land leveling. The first inward-facing inclined beam soil guide 23 and the second inward-facing inclined beam soil guide 24 can partially overlap but not overlap in the front-to-back direction, extending the path for soil clod crushing and diversion, realizing multi-stage crushing and diversion, improving the efficiency of soil clod processing, and making the land leveling effect better.

The soil entry ends of the first outward-facing inclined beam guide 21 and the second outward-facing inclined beam guide 22 are aligned in the front-rear direction. The second outward-facing inclined beam guide 22 is located in the middle of the first outward-facing inclined beam guide 21 and is spaced apart from the first outward-facing inclined beam guide 21. The soil exit end of the second outward-facing inclined beam guide 22 is located in front of the soil exit end of the first outward-facing inclined beam guide 21. The central axis of the second outward-facing inclined beam guide 22 and the first outward-facing inclined beam guide 21 coincides with the central axis of the machine frame body 2. The first inward-facing inclined beam soil guide 23 and the second inward-facing inclined beam soil guide 24 are staggered in the front-back direction, and partially overlap or do not overlap in the front-back direction. The soil entry end of the first inward-facing inclined beam soil guide 23 is located in front of the soil entry end of the second inward-facing inclined beam soil guide 24, and the soil entry end of the first inward-facing inclined beam soil guide 23 is open, while the soil entry end of the second inward-facing inclined beam soil guide 24 is closed. The guiding angles of the first outward-facing inclined beam soil guide 21 and the second outward-facing inclined beam soil guide 22 are the same, and the guiding angles of the first inward-facing inclined beam soil guide 23 and the second inward-facing inclined beam soil guide 24 are the same.

[0052] In this embodiment, the second outward-facing inclined beam soil guide 22 is located in the middle of the first outward-facing inclined beam soil guide 21, that is, the second outward-facing inclined beam soil guide 22 is closer to the central axis of the frame body 2. This structure improves soil collection efficiency, allowing soil clods to be guided more smoothly and centrally to the inward-facing inclined beam soil guide, thereby enabling the soil clods to be broken up more efficiently by the inward-facing inclined beam soil guide. The soil outlet end of the second outward-facing inclined beam soil guide 22 is located in front of the soil outlet end of the first outward-facing inclined beam soil guide 21, ensuring sufficient spacing at the soil outlet end of the second outward-facing inclined beam soil guide 22, preventing soil clods from accumulating at the soil outlet end of the second outward-facing inclined beam soil guide 22, and further improving the efficiency of soil clod processing. The first inward-facing inclined beam soil guide 23 and the second inward-facing inclined beam soil guide 24 can partially overlap but not overlap in the front-to-back direction, extending the path for soil clod crushing and diversion, achieving multi-stage crushing and diversion, improving the efficiency of soil clod processing, and resulting in better land leveling. The entry end of the first inward-facing inclined beam soil guide 23 is open, which helps to disperse the soil to a wider area, while the entry end of the second inward-facing inclined beam soil guide 24 is closed, enhancing crushing efficiency and further improving the efficiency of soil clod processing.

[0053] Example 6

[0054] Based on Example 4, such as Figure 2As shown, this utility model provides a diversion type land leveling machine, which is equipped with two outward V-shaped inclined beam soil guides, namely the first outward V-shaped inclined beam soil guide 21 and the second outward V-shaped inclined beam soil guide 22. The first outward V-shaped inclined beam soil guide 21 and the second outward V-shaped inclined beam soil guide 22 are arranged side by side with a gap between them. The first outward V-shaped inclined beam soil guide 21 and the second outward V-shaped inclined beam soil guide 22 are symmetrically arranged along the central axis of the frame body 2. An inward V-shaped inclined beam soil guide is formed between the first outward V-shaped inclined beam soil guide 21 and the second outward V-shaped inclined beam soil guide 22. This device is also equipped with a first inward V-shaped inclined beam soil guide 23 and a second inward V-shaped inclined beam soil guide 24. The first inward-facing inclined beam soil guide 23 and the second inward-facing inclined beam soil guide 24 are staggered in the front-back direction, and partially overlap or do not overlap in the front-back direction. The soil entry end of the first inward-facing inclined beam soil guide 23 is located in front of the soil entry end of the second inward-facing inclined beam soil guide 24, and the soil entry end of the first inward-facing inclined beam soil guide 23 is open, while the soil entry end of the second inward-facing inclined beam soil guide 24 is closed. The guiding angles of the first outward-facing inclined beam soil guide 21 and the second outward-facing inclined beam soil guide 22 are the same, and the guiding angles of the first inward-facing inclined beam soil guide 23 and the second inward-facing inclined beam soil guide 24 are the same.

[0055] In this embodiment, the first outward-facing inclined beam soil guide 21 and the second outward-facing inclined beam soil guide 22 are arranged side by side, forming an inward-facing inclined beam soil guide between them. This enhances the soil-breaking capacity of the outward-facing inclined beam soil guide and improves the efficiency of soil clod processing. The first inward-facing inclined beam soil guide 23 and the second inward-facing inclined beam soil guide 24 can partially overlap in the front-back direction but do not overlap, extending the path for soil clod breaking and diversion, achieving multi-stage breaking and diversion, improving the efficiency of soil clod processing, and resulting in better land leveling. The entry end of the first inward-facing inclined beam soil guide 23 is open, which helps to disperse the soil to a wider area, while the entry end of the second inward-facing inclined beam soil guide 24 is closed, enhancing the breaking efficiency and further improving the soil clod processing capacity.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
