Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a novel no-till seeder. Background Technology

[0002] Conservation tillage is an important agricultural technique in my country, a new agricultural cultivation technique that has developed in recent years. It involves sowing seeds on land that has not been tilled. This cultivation technique can improve soil fertility, improve soil structure, and is beneficial for water retention and moisture conservation. It is currently a widely promoted technique, and no-till seeders are the key to implementing conservation tillage.

[0003] No-till seeding operates on uncultivated land. Due to the hard soil and surface cover such as straw and dry grass, no-till seeders must possess excellent capabilities in cutting through cover and creating furrows. Their structure typically includes a frame, weeding mechanism, fertilizer bin, fertilizer and furrow opener, depth limiting mechanism, four-bar linkage, seed bin, seed metering device, seed and furrow opener, and soil compaction wheel. However, excessively long longitudinal length can lead to poor stability, inadequate force distribution, and an inability to effectively operate on complex, uneven, or poorly shaped terrain, resulting in suboptimal performance. Utility Model Content

[0004] Therefore, one objective of this utility model is to propose a new type of no-till planter to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, this utility model provides a novel no-till seeder, comprising a machine body and a seeding unit. A suspension frame is installed on the upper front of the machine body, and a straw cutting and cleaning device is installed on the lower part of the machine body. The rear of the machine body is rigidly connected to the seeding unit through a pre-compression device. A fertilizer box is provided on the upper part of the machine body, and an electronic fertilizer dispensing device is provided below the fertilizer box.

[0006] Furthermore, the pre-compression device includes an actuator and a vertical slide rail. The vertical slide rail includes an inner slide rail and an outer slide rail. The output end of the actuator is connected to the inner slide rail via a fixing nut. The outer slide rail is sleeved outside the inner slide rail. The inner slide rail is rigidly connected to the seeding unit, and the outer slide rail is rigidly connected to the frame.

[0007] Furthermore, the actuator is a hydraulic cylinder or a pneumatic cylinder, and the hydraulic cylinder or pneumatic cylinder is equipped with a pressure sensor for sensing pressure changes. The pressure sensor monitors the pressure changes in real time. The output end of the hydraulic cylinder or pneumatic cylinder moves to make the outer slide and the inner slide slide relative to each other, thereby driving the seeding unit to move.

[0008] Furthermore, the straw cutting and cleaning device includes a straw cutting blade and a straw throwing wheel. The straw cutting blade is located at the lower front of the machine body, and the straw throwing wheel is located on the machine body and on both sides behind the straw cutting blade.

[0009] Furthermore, the straw cutting blade has a notched disc structure, and the straw throwing wheel has an arc-shaped, finger-like disc structure. The straw throwing wheel is arranged symmetrically in a figure-eight shape, with the two wheels having staggered spring teeth. The straw cutting blade cuts the straw, and the straw throwing wheel throws the cut straw to create a clean seedling strip area.

[0010] Furthermore, the sowing unit includes a sowing furrow opener and a soil covering and pressing wheel. The sowing furrow opener is used to break the soil and open sowing furrows, and the soil covering and pressing wheel is used to cover the sowing furrows with soil after sowing. The sowing furrow opener is located in the formed clean seedling zone area so that the sowing furrows opened by breaking the soil are on the clean seedling zone area.

[0011] Furthermore, the body is an integral frame structure, the suspension frame is used for rigid connection with the tractor's three-point suspension system, and the electronic fertilizer applicator is used to control the amount of fertilizer applied.

[0012] Furthermore, when the straw cutting blade is in operation, the arc-shaped part of the blade enters the soil, and the soil provides resistance to it, driving the straw cutting blade to rotate passively.

[0013] Furthermore, the notch depth of the straw cutter is 20-70mm, and the diameter of the disc is 400-500mm.

[0014] Furthermore, the machine body integrates and connects the straw cutting and cleaning device, the pre-compression device, and the seeding unit to form a single operation unit, and the seeder includes several single operation units arranged side by side.

[0015] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0016] This invention eliminates the four-bar linkage mechanism commonly used in current seeders, and adopts a rigid connection between the frame and the seeding unit, which shortens the length of the machine body, improves the stress on the machine body, and enhances the stability of the seeder during operation.

[0017] This utility model designs a pre-compression device for a seeder, which adopts a constant pressure design of a hydraulic system. Through a vertical slide, it realizes the conformal shape of the seed unit and a constant force on the soil, which improves the machine's responsiveness to complex plots, enhances the stability of the machine structure, and better meets the needs of the machine to operate in complex plots.

[0018] This utility model of machinery completes all sowing operations in one operation, including straw cutting, straw throwing, precise side-deep fertilization, precision sowing, and soil covering and compaction. It reduces the number of operation steps, lowers the operation cost, improves the operation efficiency, and reduces the compaction of the soil by the machinery.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figure 1-9 As shown, this utility model provides a novel no-till seeder, including a body 1 and a seeding unit 2. A suspension frame 3 is installed on the upper front of the body 1, and a straw cutting and cleaning device 4 is installed on the lower part of the body 1. The rear of the body 1 is rigidly connected to the seeding unit 2 through a pre-compression device 5. A fertilizer box 6 is provided on the upper part of the body 1, and an electronic fertilizer discharge device 7 is provided below the fertilizer box 6.

[0034] Understandably, the machine body 1 serves as the skeleton to support all components. The suspension frame 3 is installed at the front and upper part for rigid connection with the tractor's three-point suspension. The straw cutting and cleaning device 4 is located below to handle the surface cover. The pre-compression device 5 is rigidly connected to the seed unit 2 at the rear of the machine body 1. The fertilizer box 6 and the electronic fertilizer dispensing device 7 are placed above the machine body 1 to achieve precise fertilization. This design, by eliminating the traditional four-bar linkage, shortens the longitudinal length of the implement, improves structural rigidity and stability, and ensures effective contact between the seed unit 2 and the soil. It enhances adaptability and operational sensitivity in complex terrains (such as uneven plots), thereby solving the problems of poor force distribution and operational quality caused by excessively long implements in existing technologies.

[0035] Furthermore, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the pre-compression device 5 includes an actuator 8 and a vertical slide 9. The vertical slide 9 includes an inner slide 10 and an outer slide 11. The output end of the actuator 8 is connected to the inner slide 10 through a fixing nut 12. The outer slide 11 is sleeved outside the inner slide 10. The inner slide 10 is rigidly connected to the seeding unit 2, and the outer slide 11 is rigidly connected to the frame.

[0036] Understandably, in terms of function, the vertical slide 9 allows the seeding unit 2 to move up and down, and the actuator 8 (which is a hydraulic or pneumatic system) drives the slide to slide relative to each other, so as to realize the contour movement of the seeding unit 2; by maintaining a constant working pressure (such as real-time monitoring and feedback by a pressure sensor), it ensures that the seeding unit 2 maintains stable contact under complex surface conditions, improves the accuracy of furrowing and sowing, shortens the length of the implement and optimizes the force distribution, and enhances the structural stability and operation quality.

[0037] Furthermore, the actuator 8 is a hydraulic cylinder or a pneumatic cylinder. The hydraulic cylinder or pneumatic cylinder is equipped with a pressure sensor for sensing pressure changes. The pressure sensor monitors the pressure changes in real time. The output end of the hydraulic cylinder or pneumatic cylinder moves to make the outer slide rail 11 and the inner slide rail 10 slide relative to each other, thereby driving the seeding unit 2 to move.

[0038] The seeder operates on uneven soil surfaces, and the force exerted by the seed unit 2 on the soil varies with the undulations of the ground. Consequently, the depth of the furrowing component (furrow opener 15) of the seed unit 2 also varies, making it impossible to guarantee consistent sowing depth and affecting the sowing operation. This device incorporates a pressure sensor in the seeder's pressure system to detect pressure changes in real time and transmit the data to the system's control unit (not shown in the figure). If the pressure change reaches a set value, the control solenoid valve opens, supplementing or releasing pressure on the actuator 8 in the pre-compression device 5, causing the hydraulic (pneumatic) cylinder of the actuator 8 to extend or shorten. The actuator 8 is rigidly connected to the inner slide rail 10 via the actuator 8 fixing nut 12. The inner slide rail 10 is also rigidly connected to the seed unit 2, and the outer slide rail 11 is rigidly connected to the frame. Both the inner and outer slide rails 10 have rectangular cross-sections. Thus, when the actuator 8 operates, the inner slide rail 10 can only move the seed unit 2 vertically along the outer slide rail 11, ensuring a constant force exerted by the furrowing blade of the seed unit 2 on the soil, thereby guaranteeing the consistency of the furrowing depth of the seed unit 2.

[0039] Furthermore, the straw cutting and cleaning device 4 includes a straw cutting blade 13 and a straw throwing wheel 14. The straw cutting blade 13 is located at the lower front of the machine body 1, and the straw throwing wheel 14 is located on the machine body 1 and on both sides behind the straw cutting blade 13.

[0040] Understandably, the cutting blade cuts through the soil and the throwing wheel throws away the residue by rotating, ensuring that the subsequent sowing area is unobstructed. This avoids the problem of straw blockage under no-till conditions, improves the efficiency of ditching and sowing, reduces machine resistance, avoids seed and fertilizer mixing, and improves the cleanliness of the seedling strip to ensure germination rate.

[0041] Furthermore, the straw cutting blade 13 has a notched disc structure, and the straw throwing wheel 14 has an arc-shaped, finger-like disc structure. The straw throwing wheel 14 is arranged symmetrically in a figure-eight shape, with the two wheels having staggered spring teeth. The straw cutting blade 13 cuts the straw, and the straw throwing wheel 14 throws the cut straw away to form a clean seedling belt area.

[0042] Furthermore, such as Figure 7 As shown, the straw cutter 13 includes several arc-shaped portions 17, and a notch 18 structure is provided between adjacent arc-shaped portions 17. The arc-shaped portions 17 of the straw cutter 13 are equipped with cutting edges, and the notch 18 structure is used to collect straw.

[0043] Understandably, the notch 18 structure of the notch-type disc cutter actively collects straw to the notch 18 as it moves forward, and the arc-shaped cutting edge passively rotates and cuts under soil resistance. Compared to traditional straight-blade cutters, it is more labor-saving and particularly suitable for uneven furrow terrain, thus solving the problem of reduced sowing quality caused by incomplete straw collection.

[0044] Furthermore, the straw throwing wheel 14 is an arc-shaped, toothed disc, and one straw cutting blade 13 is provided with two straw throwing wheels 14. The two straw throwing wheels 14 are inclined and arranged symmetrically in a figure-eight shape, with the front narrower and the back wider in the horizontal direction.

[0045] It is understandable that, such as Figure 9 As shown, the figure-eight layout of the arc-shaped toothed disc forms an outward spreading channel. When the toothed disc rotates, it guides the cut straw along the arc surface to the outside of the seedling strip, thus solving the problem of residual straw in the seedling strip affecting ditching.

[0046] Furthermore, the sowing unit 2 includes a sowing furrow opener 15 and a soil covering and pressing wheel 16. The sowing furrow opener 15 is used to break the soil and open sowing furrows, and the soil covering and pressing wheel 16 is used to cover the sowing furrows with soil after sowing. The sowing furrow opener 15 is located in the formed clean seedling zone area so that the sowing furrows opened by breaking the soil are on the clean seedling zone area.

[0047] The seeding unit 2 includes a seeding furrow opener 15 and a soil covering and compaction wheel 16. The seeding furrow opener 15 breaks the soil and opens furrows in the clean seedbed area, and the compaction wheel then covers and compacts the soil. The furrow opener precisely opens furrows and sows in the area cleaned by the straw-throwing wheel 14, and the compaction wheel compacts the soil to cover the seed furrows. By optimizing the position, straw interference is avoided, and furrow opening, sowing, and soil covering are completed in one operation, improving seed germination rate and shortening the operation process to increase efficiency.

[0048] Furthermore, the body 1 is an integral frame structure, the suspension frame 3 is used for rigid connection with the tractor's three-point suspension system, and the electronic fertilizer applicator 7 is used to control the amount of fertilizer applied.

[0049] The body 1 serves as an integrated platform that supports all components. The suspension frame 3 is rigidly connected to the tractor's three-point suspension to ensure stable power transmission. At the same time, the overall frame of the body 1 distributes the stress, avoiding the deformation of traditional segmented structures.

[0050] Furthermore, the straw cutting blade 13 adopts a passive rotation design, relying on soil resistance to drive its rotation.

[0051] Understandably, when the straw cutter 13 is working, the arc-shaped part 17 of the blade enters the soil, and the soil provides resistance, driving the straw cutter 13 to rotate passively. Utilizing the soil reaction force achieves self-driven cutting, reducing additional power requirements, lowering the tractor load, improving cutting efficiency, and adapting to different soil hardness conditions.

[0052] Furthermore, the notch 18 of the straw cutting blade 13 has a depth of 20-70mm, and the disc 19 has a diameter of 400-500mm.

[0053] Understandably, the notch 18 depth of the straw cutter 13 is designed to accommodate various straw thicknesses, and its diameter is designed to balance the cutting range and soil penetration depth. Parametric optimization ensures the versatility of the straw cutter 13 in cutting straw of different diameters.

[0054] Furthermore, the machine body 1 integrates and connects the straw cutting and cleaning device 4, the pre-compression device 5, and the seeding unit 2 to form a single operation unit, and the seeder includes several single operation units arranged side by side.

[0055] This utility model defines a single-operation unit integrated into the body 1 and its side-by-side arrangement. Each unit (including straw processing, pre-compression device 5 and sowing unit 2) independently completes cutting, throwing, fertilizing, sowing and compaction. Multiple units are arranged side by side to achieve wide-area operation. The modular design improves efficiency and supports high-efficiency operation in large-scale farmland.

[0056] like Figure 1As shown, in one embodiment, a seeder has four single-operation units, meaning it can simultaneously sow seeds on four ridges, greatly improving operational efficiency.

[0057] In one embodiment, such as Figure 8 As shown, it also includes structures such as an upper suspension 20, a lower suspension 21, a support arm 22, a suspension beam 23, a seed metering device 24, a seed box 25, a seed pressing wheel 26, a seed guide tube 27, a seed furrow guard plate 28, and a seed furrow opening shovel. Among them, the upper suspension 20 is used to connect to the tractor lifting arm and control the lifting of the whole machine; the lower suspension 21 is fixed to the tractor lower lever and transmits traction force; the support arm 22 is used to connect and install the straw cutter 13; the suspension beam 23 is the main frame for installing the working unit and bears the working parts; the seed metering device 24 is used to control seed dispensing; the seed box 25 is used to store seeds and ensure continuous seed supply; the seed pressing wheel 26 compacts the soil in the seed furrow to ensure that the seeds contact the soil moisture; the seed guide tube 27 guides the seeds from the seed metering device 24 to fall accurately into the seed furrow; the seed furrow opener 15 breaks the soil to open the seed furrow; and the seed furrow guard plate 28 prevents the seed furrow from collapsing and maintains the shape of the furrow.

[0058] Since this application integrates the straw cutting and cleaning device 4 and eliminates the four-bar linkage mechanism of commonly used seeders on the basis of the original seeder (seeding unit 2), the improvement is made by rigidly connecting the machine body 1 and the seeding unit 2 through the pre-compression device 5. The seeding unit 2 is an existing mature machine, and its specific structure and connection method will not be described in detail here.

[0059] Working Principle: The novel no-till seeder without a four-bar linkage is suspended from the rear three-point suspension of a tractor and is towed by the tractor. The implement is connected to the rear three-point suspension of the tractor via the suspension frame 3, which drives the implement's lifting and lowering and operation. During operation, the tractor's forward movement is controlled by the suspension frame 3, which controls the forward and vertical position of the machine body 1. The straw cutting and cleaning device 4, installed on the lower part of the machine body 1, completes the straw cutting and cleaning work, and the seeding furrow opener 15 completes the furrow opening work, providing suitable fertilizer furrows for the electronic fertilizer dispensing device 7, ensuring the completion of precision fertilization. The straw cutting blade 13 has a notched disc structure. During operation, the arc-shaped part 17 of the blade enters the soil, where the soil provides significant resistance, driving it to rotate passively and achieving labor-saving straw cutting. The straw throwing wheel 14 adopts an arc-shaped, finger-like disc structure. The finger-like discs are arranged on both sides behind the straw cutting blade 13 and are in contact with the soil. When the machine moves, the soil resistance drives its rotation. It is inclined, with the two wheels forming a figure-eight shape and the spring teeth of the two wheels arranged in an alternating pattern to ensure the overlap of the spring teeth as they sweep across the ground, allowing it to effectively throw the straw into the seedling belt and ensuring the cleaning effect of the straw in the seedling belt. The seeder pre-compression device 5 is fixed to the rear of the machine body 1 and is rigidly connected to the seeding unit 2. It applies constant pressure to the seeding unit 2, ensuring that the seeding unit 2 has a constant working pressure on the soil, thereby ensuring effective contact between the seeding unit 2 and the soil and ensuring high-quality sowing operations. The seeder pre-compression device 5 consists of a vertical slide 9, a hydraulic (pneumatic) system, and a pressure sensor. During operation, the sensor detects changes in the oil (air pressure) and maintains a constant pressure through the hydraulic (air pressure) system, allowing the seeding unit 2 to move up and down along the vertical slide 9, thus maintaining a constant pressure of the seeding unit 2 on the soil. This structural design effectively ensures that the seeding unit 2 is in good contact with the soil, significantly shortens the machine length, improves the machine's responsiveness to complex plots, enhances the stability of the machine structure, and better meets the operational needs of complex plots.

[0060] No-till planters operate on uncultivated land under complex conditions, such as hard soil and a large amount of straw and dry grass cover. This necessitates excellent capabilities in cutting through cover and creating furrows. Currently, commonly used models are mostly towed or suspended types. The implement structure typically consists of a weeding mechanism, a four-bar linkage, a seed box, a seed metering device, a seed and furrow opener, and a soil covering and pressing wheel. Excessive implement length leads to poor stress distribution and instability. To improve straw cutting and soil penetration, the implement's weight is often increased, resulting in excessive weight that affects maneuverability, leading to inconsistent work quality and unsatisfactory results.

[0061] This invention eliminates the four-bar linkage mechanism commonly found in current seeders, employing a rigid connection between the machine body 1 and the seed unit 2. This shortens the length of the implement, improves its stress distribution, and enhances the stability of the seeder. A pre-compacting device 5 is designed, utilizing a constant-pressure hydraulic (pneumatic) system. Through a vertical slide rail 9, it achieves the contouring of the seed unit 2 and a constant force on the soil, improving the implement's responsiveness to complex terrain and enhancing its structural stability, thus better meeting the needs of the implement in complex field conditions. This invention allows the implement to complete all seeding operations in a single operation, including straw cutting, straw removal, precise side-deep fertilization, precision seeding, and soil covering and compaction. This reduces operational steps, lowers operating costs, increases efficiency, and reduces soil compaction.
