Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a high-performance ditching and wide-width combined seeding tractor-mounted machine. Background Technology
[0002] Agricultural mechanization is an inevitable trend in modern agricultural development, with sowing being a key component. Traditional sowing typically involves multiple steps, including fertilization, rotary tillage, land preparation, furrowing and compaction, sowing, covering with soil, and compaction, each performed by different agricultural machinery. This step-by-step approach suffers from low production efficiency, long operating cycles, high fuel consumption, high labor costs, and severe soil compaction due to multiple field visits, making it difficult to meet the demands of modern large-scale agriculture for high efficiency, low cost, and high quality.
[0003] To address these issues, combined seeders have emerged. Most existing combined seeders integrate fertilization, rotary tillage, and sowing functions into one unit, enabling multiple tasks to be completed in a single operation, effectively improving work efficiency. However, in practical applications, these existing combined seeders still have many shortcomings. For example, land preparation is often unsatisfactory, with insufficient soil breaking up and uneven surfaces affecting the consistency of subsequent furrowing and sowing depths; the furrowing device is poorly designed, easily catching weeds and accumulating soil, making it difficult to form regular planting furrows; the post-sowing compaction process often lacks coordination with the sowing unit, resulting in poor soil covering and compaction, affecting seed germination rates. Furthermore, the power transmission system of existing equipment is not compact and efficient enough, with limited wide-area operation capabilities, making it difficult to adapt to depth and row spacing adjustments under different agronomic requirements.
[0004] Therefore, there is an urgent need to develop a high-performance wide-span combined seeder that integrates efficient fertilization, precision rotary tillage, land leveling, smooth ditching, accurate sowing, and effective compaction to overcome the shortcomings of existing technologies and meet the needs of modern agricultural production.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] according to Figure 1 As shown, a high-performance ditching and wide-width combined seeding tractor-mounted machine includes: a frame 1, a suspension frame 2 at the top front end of the frame 1, and a tractor connected to the tractor vehicle via the suspension frame 2; the frame 1 is provided with a fertilizer application device 3, a rotary tillage device 4, a land preparation device, a ditching device, a vibratory roller 5, a seeder 6, and a rubber pressure roller 7 in sequence from front to back.
[0019] The rotary tillage device 4 is fixedly installed at the bottom of the suspension frame 2, and the fertilizer application device 3 is fixedly installed at the front end of the suspension frame 2; the top of the rotary tillage device 4 is provided with a transfer case 8, the transfer case 8 has an input shaft and multiple output shafts, and the input shaft is connected to the drive shaft of the tractor through a transmission shaft; the rotary tillage device 4 and the fertilizer application device 3 are respectively connected to the corresponding output shafts of the transfer case 8 through driven shafts.
[0020] The land preparation device includes a ground-simulating soil-smoothing plate 9, the top of which is hinged to the tail of the rotary tiller 4 via a horizontal shaft, and a spring support rod 10 is hinged between the ground-simulating soil-smoothing plate 9 and the rotary tiller. The ditching device consists of multiple dovetail soil-dividing plates 11 fixedly installed at the bottom of the ground-simulating soil-smoothing plate 9, with each dovetail soil-dividing plate 11 spaced apart along the length of the ground-simulating soil-smoothing plate 9.
[0021] The rotary tillage device 4 has rearwardly extending support arms 12 on both sides of its top. Each support arm 12 has a positioning plate 13 at its tail. Each support arm 12 has a swing arm 14 hinged to its middle section. The two swing arms 14 have an adjustment plate 15 that cooperates with the positioning plate 13 in their middle sections. The vibrating roller 5 is located at the free end of the swing arm 14.
[0022] The frame 1 has a vertically mounted lifting screw 16 at its rear. The lifting screw 16 has a handwheel 17 at its top and a horizontal sowing beam 18 at its bottom. Multiple seeders 6 are configured, each connected to the sowing beam 18 via a bracket 19. A seed metering device 20 is located at the top of the frame 1, and the seed metering device 20 has multiple seed metering hoses 21, each connected to a corresponding seeder 6. Each seeder 6 has a trailing arm 22 at its rear, and a rubber pressure roller 7 is located at the end of the trailing arm 22.
[0023] This technical solution provides a high-performance wide-width combined seeding tractor. Its core design concept is to complete all seeding operations, including fertilization, rotary tillage, land preparation, ditching and compaction, seeding, and soil covering and compaction, in one pass through a highly integrated structure and optimized component layout. It aims to solve the problems of low efficiency, poor effect, and insufficient adaptability of traditional step-by-step operations and existing combined seeders.
[0024] The machine frame 1 serves as the main load-bearing structure, connected to the tractor unit via a suspension frame 2 at its front end. During operation, the tractor unit provides power and pulls the machine forward. The operation process strictly follows the agronomic requirements: the fertilization device 3 first applies fertilizer to the surface, the rotary tillage device 4 then tills and breaks up the soil, initially mixing the fertilizer into the soil, the land preparation device scrapes and levels the tilled soil, and the furrowing device creates neat planting furrows on the leveled land. The vibrating roller 5 lightly vibrates and compacts the bottom of the planting furrows, preparing an ideal seedbed for sowing. The subsequent seeder 6 precisely sows the seeds into the compacted planting furrows, and the rubber roller 7 finally covers the soil and compacts it to ensure close contact between the seeds and the soil. Both the fertilization device 3 and the seed metering device use an air-blowing electronic control system for more precise operation.
[0025] This sequential layout ensures that each process is carried out under the optimal conditions created by the previous process, achieving highly efficient assembly-line operations. Completing all tasks in a single site visit greatly improves production efficiency, shortens the work cycle, reduces fuel consumption and labor costs, and avoids soil compaction caused by multiple site visits.
[0026] The transfer case 8 is the core power distribution hub. Its input shaft is connected to the drive shaft of the tractor via a transmission shaft to obtain power. The multiple output shafts of the transfer case 8 then transmit power separately and synchronously to the rotary tiller 4 and the fertilizer 3 through universal joints and other structures, driving them to work. By concentrating the power source near the suspension frame 2 and distributing it uniformly through the transfer case 8, complex and lengthy transmission chains are avoided, resulting in a more compact overall structure, higher power transmission efficiency, and reduced power loss. This design ensures that the operating speed of the two major power-consuming units, fertilization and rotary tillage, is synchronized with the machine's forward speed, guaranteeing the stability of fertilizer application and tillage depth.
[0027] The rotary tiller 4 breaks up the soil. Following closely behind is the articulated ground-shaping plate 9, which uses its plate-like structure to scrape and initially level the soil clods raised by the rotary tiller. A spring strut 10 provides downward pressure to the ground-shaping plate 9 and provides elastic cushioning according to ground undulations, allowing the plate to adhere closely to the ground and adapt to uneven terrain. The design of the ground-shaping plate 9 solves the problem of "unsatisfactory land preparation effect" in traditional combined seeders 6. It effectively breaks up large clods of soil after rotary tillage and achieves surface leveling, providing a flat working surface for subsequent furrowing operations, thus ensuring consistency in furrowing and sowing depth. Multiple dovetail-shaped soil-dividing plates are fixed at a certain interval to the bottom of the ground-shaping plate 9. As the machine moves forward, these plates enter the soil like plowshares, using their unique dovetail shape to smoothly divert the soil to the sides and forward, forming a neat and smooth planting furrow. The streamlined design of the dovetail shape greatly reduces resistance and effectively avoids grass snagging and soil clogging. Furthermore, it ensures that the seed furrows are stable in shape and consistent in depth, creating excellent conditions for precise sowing and promoting uniform seedling emergence.
[0028] After furrowing and before sowing, the vibrating roller 5 lightly compacts the bottom of the furrow, ensuring the seeds settle firmly at a uniform depth and resulting in better germination. It is mounted on a hinged mechanism consisting of a support arm 12, a swing arm 14, an adjusting plate 15, and a positioning plate 13. By changing the connection positions of different holes on the adjusting plate 15 and the positioning plate 13, the angle of the swing arm 14 can be altered, thereby precisely adjusting the height of the vibrating roller 5 above the ground. This controls the intensity of the compaction and the depth of the furrow, preventing seeds from sinking too deeply after sowing and ensuring a uniform sowing depth.
[0029] Multiple seeders 6 are mounted on a seeding beam 18 via brackets 19. By rotating the top handwheel 17 and adjusting the lifting screw 16, the height of the seeding beam 18 can be adjusted uniformly across all seeders 6, achieving a consistent furrowing depth. A seed metering device 20 delivers seeds to each seeder 6 via a flexible hose. Each seeder 6 has a rubber pressure roller 7 connected to its tail via a drag arm 22, with a space of less than one centimeter, providing excellent compaction and preventing soil adhesion. The seeding beam 18 is designed for multi-row seeding, and its overall lifting mechanism ensures consistent seeding depth between rows. The spacing between the seeders 6 is adjustable to meet the row spacing requirements of different crops. The drag arm 22 structure ensures that the rubber pressure roller 7 closely follows each seeder 6, achieving instantaneous linkage between seeding and compaction. This results in timely and uniform compaction, effectively ensuring close contact between seeds and soil and significantly improving germination rate.
[0030] The working principle of this technical solution is to form a coherent and efficient operation system through a highly integrated and sequential layout, combined with innovative designs such as efficient central power distribution, flexible leveling, smooth ditching, adjustable seedbed pretreatment, and linked sowing and compaction. This system achieves precise sowing and effective compaction with fine land preparation, standardized ditching, and consistent depth, significantly improving sowing quality.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
