Description

Technical Field

[0001] This invention relates to the field of combined tillage machine technology, and in particular to a foldable dry-seeding and wet-output split-flow tillage machine. Background Technology

[0002] Combined tillage machines are the core supporting agricultural machinery for the dry-seeding and wet-harvesting cotton planting mode. They are indispensable in the large-scale cotton planting in the main cotton-producing areas of southern Xinjiang Uygur Autonomous Region, my country. With the large-scale promotion of water-saving agriculture and dry-seeding and wet-harvesting technology, tillage equipment technology continues to iterate and upgrade to meet the needs of high-standard cotton field tillage.

[0003] In the mid-to-late 20th century, cotton fields in Xinjiang Uygur Autonomous Region primarily relied on flood irrigation and winter-spring irrigation for soil preparation and sowing. Early tillage machinery was simple in structure and single-function, mostly consisting of single scrapers or single soil-crushing devices. This required multiple machines for harrowing, leveling, and compaction, operating in stages, resulting in cumbersome procedures and severe soil compaction. In the 21st century, the rapid popularization of dry-sowing and wet-emergence water-saving planting techniques led to the elimination of winter and spring irrigation in cotton fields, replaced by dry-sowing and drip irrigation under mulch after sowing. This placed stringent demands on tillage quality, requiring a firm topsoil and loose subsoil, a perfectly level surface, and the elimination of waterlogging. Integrated combined tillage machines gradually became the mainstream model. In recent years, the continuous expansion of large-scale, contiguous cotton fields has led to a surge in demand for wide-width tillage equipment. However, traditional wide-width combined tillage machines generally suffer from drawbacks such as the inability to be folded and high resistance and difficulty in traction on soft soil. In addition, existing conventional wide-span dry-seeding and wet-laying land preparation equipment has the following drawbacks: First, the existing models have separate scraping, soil-breaking, and compaction components, requiring multiple round trips in the field, resulting in low land preparation efficiency. The efficiency of traditional machinery in the field is only 25-32 mu / day. Second, the land preparation effect is poor. A single operation cannot achieve multi-level effective leveling, layered soil breaking, and double compaction. The large differences in land elevation lead to problems such as waterlogging and seedling emergence during drip irrigation, and localized water shortages that prevent seedling emergence, directly causing a decrease in cotton seedling emergence rate of 8%-15%. Third, the fixed frame cannot be adapted to small, scattered cotton fields, resulting in poor equipment versatility, high idle rates, and low return on investment for farmers. Dry-seeding and wet-laying technology can save 100-120 cubic meters of water per mu. 3 With a water-saving rate of over 20%, this technology is currently being promoted in over 10 million mu of cotton fields in Xinjiang Uygur Autonomous Region. However, there is a shortage of mature models that are compatible with foldable and integrated combined tillage systems, and the market urgently needs multi-functional foldable combined tillage equipment. Summary of the Invention

[0004] In view of this, the present invention proposes a foldable dry-seeding and wet-output split-flow land preparation machine, which aims to solve at least one of the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention provides a foldable dry-seeding and wet-output split-flow land preparation machine, comprising: The frame has a traction frame at its front end; The traveling wheel assembly includes a left lifting wheel assembly and a right lifting wheel assembly disposed in the middle of the frame; the left lifting wheel assembly and the right lifting wheel assembly are arranged at intervals along the width direction of the frame and can jointly drive the frame to lift. A flipping frame, which is hinged to the side of the frame in the width direction, and has two usage states: flipped to the top of the frame and flipped to the side in the width direction of the frame; The soil crushing and compaction assembly is provided at corresponding positions at the rear of the frame and the tilting frame; the soil crushing and compaction assembly includes a soil crushing roller, a compactor and a smooth compaction roller arranged sequentially from front to back. The soil scraping assembly is located below the frame, at the front and rear of the traveling wheel assembly.

[0007] This invention employs a folding structure combining a frame and a tilting frame, along with an integrated design of the walking wheel set, soil crushing and compaction components, and soil scraping components. This integrates multiple land preparation processes—scraping, crushing, and compacting—into a single unit, enabling one-time compound operations and reducing the number of times the tractor needs to enter the field. The tilting frame can be flipped to the top or side of the frame, allowing for switching between the machine's working width and transport width, facilitating relocation and adapting to different plot sizes. The frame is raised and lowered via the left and right lifting wheel sets. The machine's depth of penetration into the soil is uniformly adjusted to adapt to different soil conditions. The scraper assembly is located in front of and behind the walking wheel assembly, which can scrape the soil on the path of the parallel walking wheel assembly, reduce the resistance of movement, and fill the wheel tracks formed by the parallel walking wheel assembly. After the smooth roller touches the ground, the frame limits the penetration depth of the compactor and the soil-breaking roller to prevent excessive penetration. At the same time, the rolling friction of the smooth roller facilitates the movement of the whole machine, reduces the resistance of movement in soft soil, and achieves continuous compaction and leveling of the soil after breaking up the soil, thereby improving the surface smoothness.

[0008] As a further improvement to the above technical solution, the soil scraping assembly includes an inner guiding soil scraping assembly and an outer guiding soil scraping assembly; The internal guide soil scraping assembly is arranged parallel to the bottom of the frame and in front of the left and right lifting wheel groups. It can scrape the soil directly in front of the left and right lifting wheel groups to reduce the travel resistance and guide the scraped soil between the left and right lifting wheel groups. The external guide soil scraping assembly is arranged parallel to the bottom of the frame and behind the left and right lifting wheel sets. It can transport the soil guided by the internal guide soil scraping assembly to the rear of the left and right lifting wheel sets to fill the compaction wheel tracks.

[0009] The beneficial effects of the above technical solution are as follows: Through the cooperation of the inner and outer guiding soil scraping components, the inner guiding soil scraping component flattens the soil in front of the left and right lifting wheel sets and guides it between them, reducing the resistance caused by the accumulation of soil in front of the left and right lifting wheel sets, making tractor traction more effortless; the outer guiding soil scraping component transports the soil guided by the inner guiding soil scraping component to the rear of the left and right lifting wheel sets, filling the wheel tracks formed by the traveling wheel sets, avoiding damage to the already leveled surface by the traveling wheel sets, and providing a preliminary flat and uniform working base for the subsequent soil crushing and compaction components, avoiding uneven soil crushing or compaction depth due to wheel track undulations.

[0010] As a further improvement to the above technical solution, the internal guide scraper assembly includes a guide scraper one and a guide scraper two; the guide scraper one and the guide scraper two are both arranged parallel to each other below the frame and are arranged in front of the left lifting wheel group and the right lifting wheel group respectively; the guide scraper one and the guide scraper two are spaced apart along the width direction of the frame, and the distance between their front ends is greater than the distance between their rear ends, so as to form an inward-curving guide structure in the shape of an eight. The external flow guiding scraper assembly includes a third and a fourth flow guiding scraper; the third and fourth flow guiding scrapers are arranged parallel to each other below the frame and are arranged one-to-one with the rear of the left and right lifting wheel sets; the front ends of the third and fourth flow guiding scrapers are joined together to form a closed end, and the rear ends are spaced apart along the width direction of the frame to form an angular external flow guiding structure.

[0011] The beneficial effects of the above technical solution are as follows: the first and second guide scrapers are arranged in a figure-eight shape with the front end spacing greater than the rear end spacing, so that the soil is naturally gathered and converged towards the middle when flowing through the first and second guide scrapers, forming an inward guiding effect, ensuring that the soil is accurately guided between the left and right lifting wheel sets; the front ends of the third and fourth guide scrapers are attached to form a closed end, and the rear ends are spaced to form an angular outward discharge structure, so that the soil guided by the inner guide scraping component is forced to be diverted to both sides, accurately covering the compaction wheel tracks of the walking wheel set, and realizing automatic filling of the soil behind the wheel; the closed end prevents soil from leaking out from the front end of the third and fourth guide scrapers, so as to avoid leaving soil ridges, thereby ensuring that all soil is transported to the wheel track position along the guiding direction and is initially scraped flat.

[0012] As a further improvement to the above technical solution, there are two tilting frames, which are hinged one-to-one on both sides of the frame in the width direction; each of the two tilting frames is provided with a soil crushing and compaction assembly at its rear; the two tilting frames can be independently tilted to the corresponding side of the frame in the width direction, and the soil crushing roller, compactor, and smooth compaction roller at their rear are connected one-to-one with the soil crushing roller, compactor, and smooth compaction roller at the rear of the frame along the width direction of the frame.

[0013] The beneficial effects of the above technical solution are as follows: the two tilting frames are respectively hinged on both sides of the width direction of the frame. After unfolding, the soil crushing roller, compactor and smooth compactor roller at the rear of the two tilting frames are connected one by one with the soil crushing roller, compactor and smooth compactor roller at the rear of the frame along the width direction to form a continuous and uninterrupted working width, ensuring the uniformity of soil crushing and compaction effect across the entire land. After folding, the width of the whole machine is greatly reduced, meeting the width restriction requirements for road transportation. The two tilting frames can be tilted independently, and can be unfolded on one side, unfolded on both sides or folded on both sides according to the operation requirements, adapting to different layout working widths.

[0014] As a further improvement to the above technical solution, the internal guide scraper assembly also includes a guide scraper five and a guide scraper six; the guide scraper five and the guide scraper six are respectively disposed on the bottom surface of the two tilting frames; when the two tilting frames are tilted to the two sides of the width direction of the frame, the guide scraper five can be connected to the front of the guide scraper one along the length direction of the guide scraper one, and the guide scraper six can be connected to the front of the guide scraper two along the length direction of the guide scraper two, so as to widen the width of the figure-eight inward guide structure.

[0015] The beneficial effects of the above technical solution are as follows: When the tilting frame is unfolded to the working state, the guide scraper five and guide scraper six set on the bottom surface of the tilting frame are connected in front of guide scraper one and guide scraper two, which widens the width of the figure-eight inward guide structure to be consistent with the working width of the whole machine, so that the soil on both sides of the frame in the folded state is also included in the guide scraping operation range, ensuring that the guide effect is uniform and consistent throughout the width range; the guide scraper five and guide scraper six can flatten the ground surface and guide and collect soil from the outside to the inside during the movement of the whole machine, so as to initially fill the wheel tracks formed by the tractor wheels.

[0016] As a further improvement to the above technical solution, the soil crushing roller includes a soil crushing roller shaft and a plurality of soil crushing discs; the soil crushing roller shaft is rotatably connected to the corresponding frame or the tilting frame and is arranged along the width direction of the corresponding frame or the tilting frame; the plurality of soil crushing discs are all coaxially fixed on the soil crushing roller shaft and are spaced apart along the length direction of the soil crushing roller shaft.

[0017] The beneficial effects of the above technical solution are as follows: the soil crushing roller adopts a structure in which the soil crushing roller shaft is coaxially fixed with multiple soil crushing discs and arranged at intervals. The soil crushing discs rotate synchronously with the soil crushing roller shaft, forming a multi-stage linear crushing effect on the soil, which can effectively crush compacted soil clods and straw residues; the gaps between each soil crushing disc allow fine soil to pass through naturally, avoiding excessive crushing or blockage, and forming a suitable tillage layer.

[0018] As a further improvement to the above technical solution, the presser includes a press roller shaft and a plurality of press rollers; the press roller shaft is rotatably connected to the corresponding frame or the turning frame and is arranged along the width direction of the corresponding frame or the turning frame; the plurality of press rollers are coaxially rotatably sleeved on the press roller shaft and are arranged sequentially along the length direction of the press roller shaft.

[0019] The beneficial effects of the above technical solution are: the compactor adopts a structure in which the compaction roller shaft and multiple compaction rollers are coaxially rotated and arranged in sequence, and each compaction roller rotates independently. It can automatically adjust the rotation state according to the softness and hardness of the surface soil, so as to uniformly compact the soil after crushing and avoid local insufficient compaction or over-compaction.

[0020] As a further improvement to the above technical solution, the pressing roller includes a hub and a plurality of pressing teeth; the hub is coaxially rotatably sleeved on the pressing roller shaft; a plurality of pressing teeth are uniformly fixed along the circumference on both sides of the outer periphery of the hub.

[0021] The beneficial effects of the above technical solution are: pressing teeth are evenly fixed on both sides of the outer periphery of the pressing roller along the circumferential direction. The pressing teeth are inserted into the soil to achieve deep compaction as the hub rotates. The distribution of double rows of pressing teeth on both sides increases the working width and compaction density of a single pressing, thereby improving the pressing effect and work efficiency.

[0022] As a further improvement to the above technical solution, the smooth pressing roller includes a wheel axle and a pressing roller; the wheel axle is rotatably connected to the corresponding frame or the turning frame, and is arranged along the width direction of the corresponding frame or the turning frame; the pressing roller is coaxially rotatably sleeved on the wheel axle and its outer peripheral wall surface is cylindrical.

[0023] The beneficial effects of the above technical solution are: the smooth roller adopts a cylindrical structure on the outer peripheral wall of the roller, and the roller rolls to finely level the surface soil after it has been compacted by the roller during its forward movement; the cylindrical surface does not adhere to soil or produce furrow marks, effectively eliminating the small unevenness left after the roller operation, achieving a flat surface, and reducing the overall machine's travel resistance.

[0024] As a further improvement to the above technical solution, a soil leveling frame is also included, which is fixed below the traction frame.

[0025] The beneficial effects of the above technical solution are: the soil leveling frame is fixed under the traction frame, and during the movement of the whole machine, it levels the soil ridges formed between the two wheels by the left and right wheels of the traction tractor, creating preliminary leveling conditions for subsequent scraping and compaction operations, reducing the working load of the rear scraping and compaction components, and improving the overall operating efficiency and land leveling quality of the whole machine.

[0026] As a further improvement to the above technical solution, the soil compaction assembly also includes a leveling shovel, which is positioned behind the smooth compaction roller.

[0027] The beneficial effects of the above technical solution are as follows: The leveling shovel is set behind the smooth pressing roller as the last working component of the whole machine. It performs final fine scraping on the surface soil after it has been compacted by the press and leveled by the smooth pressing roller, eliminating any small undulations or soil edges that may remain during the pressing and leveling process, further improving the flatness of the ground surface, and preventing the problem of water seepage or local water accumulation during later drip irrigation.

[0028] As can be seen from the above technical solutions, compared with the prior art, the foldable dry-seeding and wet-output diversion type land preparation machine disclosed in this invention has the following advantages and beneficial effects.

[0029] This invention addresses the stringent land preparation requirements of the dry-seeding, wet-harvesting planting method for cotton fields, demanding a "firm topsoil, loose bottoms, and highly level surface." It integrates four processes—primary soil scraping, soil breaking up, double compaction, and secondary fine scraping—into a single, foldable machine. Through a single field operation, it sequentially removes soil blisters, breaks up compacted soil, deeply compacts the soil, and levels the surface, resulting in a smooth surface and ideal soil structure. Its technological advantages are reflected in the following four aspects.

[0030] First, the process is integrated and sequential. Following the physical logic of soil processing, the functional modules of scraping, breaking up, compacting, and fine scraping are arranged sequentially from front to back. During operation, the broken-up soil layer is double-compacted by a compactor and a smooth compaction roller. The compactor applies pressure to the entire broken-up soil layer, forming a deep, load-bearing, dense layer. Following the compactor, the smooth compaction roller uses its own weight to moderately compact and finely level the surface soil. Its unit area pressure is relatively low and its penetration depth is shallow, so it does not damage the deep, dense structure already formed by the compactor, resulting in a moderately compact, level surface layer, creating a "solid on top, loose on the bottom" soil structure. The entire land preparation process, from coarse to fine processing, is completed step-by-step during the process, enabling the soil to reach sowing standards in a single operation.

[0031] Secondly, the method for adjusting the overall depth of the machine's penetration into the soil. Traditional tillage machines rely on hydraulic cylinders at the front traction frame to drive the rear of the frame to raise and lower, thus adjusting the overall depth of penetration. However, due to the significant increase in weight after adding the two side tilting frames, this traditional adjustment method fails because the drive structure is insufficient to stably drive the rear of the frame after the increased weight. To address this, this invention sets up left and right lifting wheel sets in the middle of the frame, directly supporting and driving the frame's raising and lowering, achieving unified adjustment of the overall depth of penetration. Simultaneously, the compaction tracks formed by the left and right lifting wheel sets during movement are leveled by the inner and outer guide scraping components, organically integrating the wheel set's walking support function, scraping and guiding function, and smooth secondary compaction and drag reduction.

[0032] Thirdly, there is the phased compaction method for soft soil. In relatively soft soil, the compactor embeds itself too deeply, increasing resistance and potentially even causing it to lose its rolling function. Under these conditions, the initial compaction depth can be adjusted using the left and right lifting wheel sets to reduce resistance and ensure normal machine movement and rolling operation. After one compaction operation, the surface soil is initially compacted, improving walking conditions. Subsequent secondary or multiple compaction operations can then be performed to gradually establish a soil structure that is firm on top and loose underneath.

[0033] Fourthly, the machine features a folding switch between transport and operation modes. The double-sided tilting frame is hydraulically driven to unfold to its full width during operation and folds upward and inward during transport, allowing the machine to simultaneously meet the width requirements for large-scale operations and the width restrictions for highway transport. The folding structure also gives the equipment universal adaptability to different-sized plots of land.

[0034] In summary, this invention takes "one-time land entry, step-by-step processing, folding and transfer, and unified control" as its main technical line, and provides a multi-stage land preparation operation mode for soft soil, thus constructing an efficient combined land preparation technology solution suitable for dry-sowing and wet-harvesting cotton fields.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0047] According to embodiments of the present invention, such as Figures 1 to 6 As shown, the foldable dry-seeding and wet-output split-flow land preparation machine includes: a frame 1, a set of walking wheels 2, a tilting frame 3, a soil crushing and compaction assembly 4, and a soil scraping assembly.

[0048] The front end of the frame 1 is equipped with a traction frame 11.

[0049] The traveling wheel set 2 includes a left lifting wheel set 21 and a right lifting wheel set 22 located in the middle of the frame 1; the left lifting wheel set 21 and the right lifting wheel set 22 are arranged at intervals along the width direction of the frame 1 and can jointly drive the frame 1 to lift.

[0050] The flip frame 3 is hinged to the side of the frame 1 in the width direction and has two usage states: flipped to the top of the frame 1 and flipped to the side in the width direction of the frame 1.

[0051] Both the frame 1 and the tilting frame 3 are equipped with soil crushing and compaction components 4 at corresponding positions at the rear. Each soil crushing and compaction component 4 includes a soil crushing roller 41, a compactor 42 and a smooth compaction roller 43 arranged sequentially from front to back.

[0052] Scraping components are provided at the front and rear of the walking wheel set 2 below the frame 1.

[0053] This embodiment employs a folding structure combining the frame 1 and the tilting frame 3, along with an integrated setup of the walking wheel set 2, the soil crushing and compaction component 4, and the soil scraping component. This integrates multiple land preparation processes—scraping, crushing, and compacting—into a single unit, enabling one-time compound operations and reducing the number of times the tractor needs to enter the field. The tilting frame 3 can be tilted to the top or side of the frame 1, allowing for switching between the machine's working width and transport width, facilitating relocation and adapting to different plot sizes. The frame 1 is raised and lowered via the left and right lifting wheel sets 21 and 22. The machine's depth of penetration into the soil is uniformly adjusted to adapt to different soil conditions. The scraping components are set in front of and behind the walking wheel group 2, which can scrape the soil on the path of the parallel walking wheel group 2, reduce the resistance of movement, and fill the wheel tracks formed by the parallel walking wheel group 2. After the smooth pressing roller 43 touches the ground, the frame 1 limits the penetration depth of the compactor 42 and the soil crushing roller 41 to prevent excessive penetration. At the same time, the rolling friction of the smooth pressing roller 43 is conducive to the movement of the whole machine, reduces the resistance of movement in soft soil, realizes continuous compaction and leveling of the soil after crushing, and improves the flatness of the ground surface.

[0054] In some embodiments, the walking wheel set 2 further includes a lifting frame 23 and a lifting drive hydraulic cylinder 24. One end of the lifting frame 23 is hinged to the middle of the frame 1, and the left lifting wheel set 21 and the right lifting wheel set 22 are both installed at the other end of the lifting frame 23. The fixed end of the lifting drive hydraulic cylinder 24 is hinged to the frame 1, and the telescopic end of the lifting drive hydraulic cylinder 24 is hinged to the other end of the lifting frame 23. The lifting drive hydraulic cylinder 24 can drive the lifting frame 23 to rotate, thereby driving the left lifting wheel set 21 and the right lifting wheel set 22 to rotate synchronously to lift off the ground, and can also press against the ground to lift the frame 1.

[0055] In some embodiments, a folding hydraulic mechanism is also included, which is mounted on the frame 1 and its drive end is connected to the tilting frame 3 for driving and controlling the tilting frame 3 to tilt above the frame 1 and to tilt to the side in the width direction of the frame 1.

[0056] In some embodiments, the folding hydraulic mechanism includes a front folding hydraulic mechanism 8 and a rear folding hydraulic mechanism 9; the front folding hydraulic mechanism 8 and the rear folding hydraulic mechanism 9 are located above the frame 1 and are spaced apart along the length of the frame 1; the drive ends of the front folding hydraulic mechanism 8 and the rear folding hydraulic mechanism 9 are both connected to the flipping frame 3 to jointly drive and control the flipping action of the flipping frame 3.

[0057] In some embodiments, the soil scraping assembly includes an inner guide soil scraping assembly 5 and an outer guide soil scraping assembly 6; The internal guide scraper assembly 5 is arranged parallel to the bottom of the frame 1 and in front of the left lifting wheel assembly 21 and the right lifting wheel assembly 22. It can scrape the soil in front of the left lifting wheel assembly 21 and the right lifting wheel assembly 22 to reduce the travel resistance, and guide and transport the scraped soil between the left lifting wheel assembly 21 and the right lifting wheel assembly 22. The external guide soil scraper assembly 6 is arranged parallel to the bottom of the frame 1 and behind the left lifting wheel assembly 21 and the right lifting wheel assembly 22. It can transport the soil guided out by the internal guide soil scraper assembly 5 to the rear side of the left lifting wheel assembly 21 and the right lifting wheel assembly 22 to fill the rolling wheel tracks.

[0058] With the cooperation of the inner guide soil scraper assembly 5 and the outer guide soil scraper assembly 6, the inner guide soil scraper assembly 5 flattens the soil in front of the left lifting wheel assembly 21 and the right lifting wheel assembly 22 and guides it between them, reducing the resistance caused by the accumulation of soil in front of the left lifting wheel assembly 21 and the right lifting wheel assembly 22, making the tractor traction more effortless; the outer guide soil scraper assembly 6 transports the soil guided out by the inner guide soil scraper assembly 5 to the rear of the left lifting wheel assembly 21 and the right lifting wheel assembly 22, filling the wheel tracks formed by the travel wheel assembly 2, avoiding damage to the already leveled ground surface caused by the travel wheel assembly 2, and providing a preliminary flat and uniform working base for the subsequent soil crushing and compaction assembly 4, avoiding uneven soil crushing or compaction depth due to undulating wheel tracks.

[0059] In some embodiments, the internal guide scraper assembly 5 includes a first guide scraper 51 and a second guide scraper 52; the first guide scraper 51 and the second guide scraper 52 are both arranged parallel to each other below the frame 1 and are arranged in front of the left lifting wheel group 21 and the right lifting wheel group 22 respectively; the first guide scraper 51 and the second guide scraper 52 are spaced apart along the width direction of the frame 1, and the distance between their front ends is greater than the distance between their rear ends, so as to form a figure-eight inward guide structure; The external flow guiding scraper assembly 6 includes a third flow guiding scraper 61 and a fourth flow guiding scraper 62. The third flow guiding scraper 61 and the fourth flow guiding scraper 62 are arranged in parallel below the frame 1 and are arranged one-to-one with the rear of the left lifting wheel group 21 and the right lifting wheel group 22. The front ends of the third flow guiding scraper 61 and the fourth flow guiding scraper 62 are joined together to form a closed end, and the rear ends are spaced apart along the width direction of the frame 1 to form an angular external flow guiding structure.

[0060] The first guide scraper 51 and the second guide scraper 52 are arranged in a figure-eight shape with the front end spacing greater than the rear end spacing. This allows the soil to naturally converge and gather towards the center as it flows through the first guide scraper 51 and the second guide scraper 52, forming an inward guiding effect. This ensures that the soil is accurately guided between the left lifting wheel assembly 21 and the right lifting wheel assembly 22. The front ends of the third guide scraper 61 and the fourth guide scraper 62 are fitted together to form a closed end, and the rear ends are spaced apart to form an angular outward discharge structure. This forces the soil guided to the rear by the inner guide scraper assembly 5 to be diverted to both sides, accurately covering the compaction wheel tracks of the walking wheel assembly 2, and achieving automatic filling of the soil behind the wheels. The closed end prevents soil from leaking out from the front ends of the third guide scraper 61 and the fourth guide scraper 62, so as to avoid leaving soil ridges. This ensures that all the soil is transported along the guiding direction to the wheel track position and is initially scraped flat.

[0061] Specifically, the front ends of guide scraper 1 51 and guide scraper 2 52 extend to both ends of the frame 1 in the width direction. The rear ends of guide scraper 3 61 and guide scraper 4 62 extend to both ends of the frame 1 in the width direction.

[0062] In some embodiments, there are two tilting frames 3, which are hinged one-to-one on both sides of the frame 1 in the width direction; each of the two tilting frames 3 is provided with a soil crushing and compaction assembly 4 at its rear; the two tilting frames 3 can be independently tilted to the corresponding side in the width direction of the frame 1, and the soil crushing roller 41, compactor 42 and smooth compaction roller 43 at their rear are connected one-to-one with the soil crushing roller 41, compactor 42 and smooth compaction roller 43 at the rear of the frame 1 in the width direction of the frame 1.

[0063] Two tilting frames 3 are respectively hinged to both sides of the frame 1 in the width direction. After unfolding, the soil crushing roller 41, compactor 42 and smooth compactor roller 43 at the rear of the two tilting frames 3 are connected one by one with the soil crushing roller 41, compactor 42 and smooth compactor roller 43 at the rear of the frame 1 in the width direction to form a continuous and uninterrupted working width, ensuring the uniformity of soil crushing and compaction effect across the entire land. After folding, the width of the whole machine is greatly reduced to meet the width restriction requirements for road transportation. The two tilting frames 3 can be tilted independently. Depending on the operation requirements, one side can be unfolded, both sides can be unfolded or both sides can be folded to adapt to different layout working widths.

[0064] Specifically, there are two sets of front folding hydraulic mechanisms 8 and two sets of rear folding hydraulic mechanisms 9. One set of front folding hydraulic mechanisms 8 and rear folding hydraulic mechanisms 9 are connected to a flipping frame 3 in a one-to-one transmission connection. The other set of front folding hydraulic mechanisms 8 and rear folding hydraulic mechanisms 9 are connected to another flipping frame 3 in a one-to-one transmission connection. They can synchronously or independently drive and control the flipping action of the two flipping frames 3.

[0065] Specifically, both the front folding hydraulic mechanism 8 and the rear folding hydraulic mechanism 9 are hydraulic cylinders, with one end hinged to the upper part of the frame 1 and the other end hinged to the upper part of the tilting frame 3, so as to drive the tilting frame 3 to tilt by extension and retraction.

[0066] In some embodiments, the internal guide scraper assembly 5 further includes a guide scraper five 53 and a guide scraper six 54; the guide scraper five 53 and the guide scraper six 54 are respectively disposed on the bottom surface of the two flipping frames 3; when the two flipping frames 3 are flipped to the two sides in the width direction of the frame 1, the guide scraper five 53 can be connected to the front of the guide scraper one 51 along the length direction of the guide scraper one 51, and the guide scraper six 54 can be connected to the front of the guide scraper two 52 along the length direction of the guide scraper two 52, so as to widen the width of the figure-eight inward guide structure.

[0067] When the tilting frame 3 is unfolded into the working state, the guide scraper five 53 and guide scraper six 54 set on the bottom surface of the tilting frame 3 are connected in front of the guide scraper one 51 and guide scraper two 52, widening the width of the figure-eight inward guide structure to be consistent with the working width of the whole machine, so that the soil on both sides of the frame 1 in the folded state is also included in the guide scraping operation range, ensuring that the guide effect is uniform and consistent throughout the entire width range; the guide scraper five 53 and guide scraper six 54 can scrape the ground surface and guide and collect the soil from the outside to the inside during the movement of the whole machine, so as to initially fill the wheel tracks formed by the tractor wheels.

[0068] Specifically, the front and rear ends of the flow guide scraper 53 and flow guide scraper 654 extend to both ends of the width direction of the flipping frame 3, respectively.

[0069] In some embodiments, the soil crushing roller 41 includes a soil crushing roller shaft 411 and a plurality of soil crushing discs 412; the soil crushing roller shaft 411 is rotatably connected to the support shaft seat at the bottom of the corresponding frame 1 or the tilting frame 3 via a bearing 10, and is arranged along the width direction of the corresponding frame 1 or the tilting frame 3; the plurality of soil crushing discs 412 are all coaxially fixed on the soil crushing roller shaft 411 and are spaced apart along the length direction of the soil crushing roller shaft 411.

[0070] The soil crushing roller 41 adopts a structure in which the soil crushing roller shaft 411 is coaxially fixed and arranged at intervals with multiple soil crushing discs 412. The soil crushing discs 412 rotate synchronously with the soil crushing roller shaft 411, forming a multi-stage linear crushing effect on the soil, which can effectively crush compacted soil clods and straw residues. The gaps between each soil crushing disc 412 allow fine soil to pass through naturally, avoiding excessive crushing or clogging, and forming a suitable tillage layer.

[0071] Specifically, multiple cutting discs 4121 are evenly distributed around the outer periphery of the soil breaking disc 412.

[0072] In some embodiments, the presser 42 includes a press roller shaft 421 and a plurality of press rollers 422; the press roller shaft 421 is rotatably connected to the support shaft seat at the bottom of the corresponding frame 1 or the tilting frame 3 via a bearing 10, and is arranged along the width direction of the corresponding frame 1 or the tilting frame 3; the plurality of press rollers 422 are coaxially rotatably sleeved on the press roller shaft 421 and are arranged sequentially along the length direction of the press roller shaft 421.

[0073] The compactor 42 adopts a structure in which the compactor roller shaft 421 and multiple compactor rollers 422 are coaxially rotated and arranged in sequence. Each compactor roller 422 rotates independently and can automatically adjust its rotation state according to the softness and hardness of the surface soil, so as to uniformly compact the soil after crushing and avoid local insufficient compaction or over-compaction.

[0074] In some embodiments, the pressing roller 422 includes a hub 4221 and a plurality of pressing teeth 4222; the hub 4221 is coaxially rotatably sleeved on the pressing roller shaft 421; a plurality of pressing teeth 4222 are uniformly fixed along the circumference on both sides of the outer periphery of the hub 4221.

[0075] The outer periphery of the pressing roller 422 has pressing teeth 4222 evenly fixed on both sides along the circumferential direction. The pressing teeth 4222 are inserted into the soil to achieve deep compaction as the hub 4221 rotates. The distribution of the double rows of pressing teeth 4222 on both sides increases the working width and compaction density of a single pressing, thereby improving the pressing effect and work efficiency.

[0076] Specifically, multiple pressing teeth 4222 on both sides of the outer periphery of the hub 4221 are staggered along the circumference of the hub 4221. The hub 4221 has a central bushing, and the central bushings of the hubs 4221 of adjacent pressing rollers 422 can make close frictional contact (during maintenance, lubricating grease can be applied between the sleeve hole of the central bushing of the hub 4221 and the pressing roller shaft 421 to improve rotational flexibility); the pressing teeth 4222 of adjacent pressing rollers 422 are designed not to contact each other to avoid mutual interference, thereby improving the independent rotational flexibility of a single pressing roller 422.

[0077] In some embodiments, the smooth pressing roller 43 includes a wheel axle 431 and a pressing roller 432; the wheel axle 431 is rotatably connected to the support shaft seat at the bottom of the corresponding frame 1 or the flipping frame 3 via a bearing 10, and is arranged along the width direction of the corresponding frame 1 or the flipping frame 3; the pressing roller 432 is coaxially rotatably sleeved on the wheel axle 431 and its outer peripheral wall surface is cylindrical.

[0078] The smooth roller 43 adopts a cylindrical structure on the outer peripheral wall of the roller 432. During its forward movement, the roller 432 rolls to finely level the surface soil after it has been compacted by the roller 42. The cylindrical surface does not adhere to soil or produce furrow marks, effectively eliminating the minor unevenness left by the roller 42 after its operation, achieving a smooth surface and reducing the overall resistance of the machine.

[0079] In some embodiments, a soil leveling frame 7 is also included, which is fixed below the traction frame 11.

[0080] The soil leveling frame 7 is fixed below the traction frame 11. During the movement of the whole machine, it levels the soil ridges formed between the two wheels of the traction tractor by the wheels on both sides. This creates preliminary leveling conditions for subsequent scraping and compaction operations, reduces the working load of the rear scraping component and the soil crushing and compaction component 4, and improves the overall working efficiency and land leveling quality of the whole machine.

[0081] In some embodiments, the soil compaction assembly 4 further includes a soil leveling shovel 44, which is disposed behind the smooth compaction roller 43.

[0082] The leveling shovel 44 is located behind the smooth pressing roller 43. As the last working component of the whole machine, it performs final fine scraping on the surface soil after it has been compacted by the presser 42 and leveled by the smooth pressing roller 43. This eliminates any small undulations or soil ridges that may remain during the compaction and leveling process, further improving the flatness of the ground surface and preventing problems such as water seepage or local water accumulation during later drip irrigation.

[0083] Specifically, the leveling shovel 44 is fixed below the rear end of the corresponding frame 1 or tilting frame 3.

[0084] Specifically, when the two tilting frames 3 are symmetrically positioned on both sides of the frame 1 in the width direction, the bottom ends of the tilting frames 3, the soil-breaking disc 412, the pressing roller 422, the pressing drum 432, and the leveling shovel 44 on the frame 1 are all on the same horizontal plane. The lifting drive hydraulic cylinder 24 can drive the lifting frame 23 to tilt, so that the left lifting wheel group 21 and the right lifting wheel group 22 press against the ground and lift the frame 1, so that the tilting frame 3, the soil-breaking disc 412, the pressing roller 422, the pressing drum 432, and the leveling shovel 44 on the frame 1 simultaneously leave the ground; moreover, the lifting drive hydraulic cylinder 24 can drive the lifting frame 23 to tilt, so that the left lifting wheel group 21 and the right lifting wheel group 22 rise away from the ground, so that the tilting frame 3, the soil-breaking disc 412, the pressing roller 422, the pressing drum 432, and the leveling shovel 44 on the frame 1 simultaneously press against the ground.

[0085] Specifically, both the left lifting wheel assembly 21 and the right lifting wheel assembly 22 are rubber-coated wheels.

[0086] Specifically, it also includes a front-mounted frame lifting hydraulic cylinder 12, with the rear end of the traction frame 11 hinged to the front end of the frame 1; the fixed end of the front-mounted frame lifting hydraulic cylinder 12 is hinged to the upper part of the front end of the frame 1, and the telescopic end of the front-mounted frame lifting hydraulic cylinder 12 is hinged to the upper middle part of the traction frame 11; when the front-mounted frame lifting hydraulic cylinder 12 extends and retracts, it can apply a moderate tilting and lifting force to the frame 1, and can also adjust the height of the front end of the traction frame 11.

[0087] Specifically, both the frame 1 and the tilting frame 3 are planar frame structures. The lengths of the guide scrapers 51, 52, 53, and 54 are all parallel to the bottom surface of the frame 1; the lengths of the guide scrapers 61 and 62 are also parallel to the bottom surface of the tilting frame 3. The frame 1 and the tilting frame 3 can be constructed using channel steel or square steel tubing. The left lifting wheel assembly 21 and the right lifting wheel assembly 22 are both rubber-lined wheels. Traction and power can be output by attaching a tractor to the towing frame. The tractor's hydraulic circuits are connected to the front lifting hydraulic cylinder 12, the front folding hydraulic mechanism 8, the rear folding hydraulic mechanism 9, and the lifting drive hydraulic cylinder 24, respectively.

[0088] This invention integrates multiple land preparation processes—folding and transporting, multi-stage scraping, soil breaking, double compaction, and fine leveling—into a single machine, enabling one-time, multi-stage dry-seeding and land preparation in cotton fields. This fundamentally changes the traditional multi-machine, multi-stage land preparation model, increasing overall field preparation efficiency by 35%-55%. Actual test data shows that a standard medium-sized machine can handle 65-85 mu (approximately 4.3-5 hectares) per day, and a single machine can meet the pre-sowing land preparation needs of 200-300 mu (approximately 13-20 hectares) of contiguous cotton fields. It is suitable for large-scale cotton cooperatives and family farms in Xinjiang Uygur Autonomous Region. The machine features integrated hydraulic control of the soil penetration depth, relying on a unified adjustment mechanism via a lifting linkage hydraulic component. This eliminates the need for manual adjustment of individual components, reducing field work and lowering the barrier to entry for manual operation. Ordinary farm machinery operators can easily learn to operate the machine after simple training.

[0089] In terms of site adaptability and transportation costs, the front and rear dual hydraulic folding mechanisms enable the retraction and extension of the double-sided frame. In the working state, it is fully unfolded, and in the transportation state, it is folded inward. The overall transportation width is reduced from 6m to less than 2.6m, which meets the width restriction standards of rural roads and provincial highways in China. It can be directly transported by road without disassembling parts. The time for a single machine to be transferred across regions is shortened from the original 2-3 hours to less than 30 minutes, and the transportation cost is reduced by more than 60%. The folding structure is also suitable for both large contiguous plots and scattered small plots, which broadens the applicable scenarios of the equipment, greatly reduces the idle rate of the equipment, and increases the utilization rate of the machine by farmers by more than 40%.

[0090] In terms of improving the quality and efficiency of dry-seeding and wet-harvesting planting, the machine's combined structure of front-end coarse scraping, end-end fine scraping, soil breaking, and double compaction creates a high-standard cotton field with a firm topsoil and loose bottom, resulting in a level surface. This significantly improves field flatness, ensures even drip irrigation, and prevents localized waterlogging and seed rot, as well as localized water shortages and dry seeds. Cotton seedling emergence rate is increased by 7%-12% compared to traditional land preparation. This high-standard land preparation combined with the water-saving dry-seeding and wet-harvesting mode saves 100-120 cubic meters of water per acre of cotton field. 3 According to the local agricultural water price in Xinjiang Uygur Autonomous Region, each mu of cotton field can save 80-110 yuan in water fees per year. After being promoted on a large scale, it not only saves agricultural water resources, but also alleviates the problem of secondary salinization of farmland in southern Xinjiang, thus improving both ecological and economic benefits.

[0091] Durability and maintenance advantages of the equipment: The whole machine adopts a modular design with a central frame, and each functional component can be disassembled and assembled independently, making it convenient for later maintenance and replacement of parts; the rubber wheels prevent the surface from being compacted due to the hard wheels, reduce soil damage after land preparation, extend the service life of the machine, and comprehensively reduce the maintenance cost of the equipment throughout its entire life cycle.
