Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a hand-held corn double-row direct seeding and ridge-forming planter without furrowing and a seeding method. Background Technology

[0002] Sowing is a crucial step in agricultural production, and its quality and timeliness directly affect crop emergence, growth, and final yield. Mechanized sowing significantly improves operational efficiency, ensures consistent sowing depth, and enables reasonable planting density, promoting uniform crop emergence and robust growth, thus laying the foundation for high and stable yields. Therefore, mechanized sowing technology has been widely applied in my country.

[0003] Corn, as a major food crop, is mainly planted in two patterns: ridge planting and flat planting, with ridge planting being more common. Traditional ridge planting typically involves two separate steps: first, specialized ridge-forming machinery is used to create ridges on the field, followed by planting machinery to open furrows, sow seeds, cover with soil, and compact the soil. However, in actual planting, because the machinery needs to enter the field multiple times, the process is not only numerous and cumbersome, reducing planting efficiency, but also repeatedly compacts the soil, easily leading to soil compaction, affecting crop growth and development, and increasing the power consumption and operating costs of agricultural machinery. Furthermore, my country's hilly and mountainous areas have a vast area of ​​arable land, with small and irregularly shaped plots. Existing large and medium-sized ridge planting machinery is difficult to widely apply due to its bulky structure and poor adaptability to terrain. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a hand-held corn double-row direct seeding and ridge-forming planter and a seeding method, which solves the problems of cumbersome seeding steps, low efficiency, high cost and difficulty in adapting to hilly and mountainous areas in the prior art.

[0005] To achieve the above and other related objectives, the present invention provides a hand-held corn double-row direct seeding and ridge-forming planter without furrowing, comprising: A walking mechanism, comprising a body, a power assembly fixedly mounted on the body for driving the body to walk, and a handrail mounted on the body; The ridge-forming and sowing mechanism includes a fixed frame fixedly installed in front of the machine body, a ridge-forming component rotatably connected to the machine body, two sowing components, and a soil-covering component; The ridging component includes a drive shaft and two sets of soil-lifting blades.

The two seeding components are respectively located on the front left and right sides of the fixed frame, and the distance between the two seeding components is greater than the distance between the two sets of soil-lifting blades. Two corn seeds are directly sown onto the ground in mid-air by two sowing components to form two rows. The power component drives the machine body to move and transmits power to two sets of soil-lifting blades. The two sets of soil-lifting blades dig up the soil between the two rows of corn seeds and throw it to both sides to form furrows. The soil is thrown out to cover the seeds sown on the ground by the sowing components and to raise the ridges. The soil-covering component is used to adjust the thickness of the soil dug up and thrown by the two sets of soil-lifting blades covering the seeds sown on the ground by the two sowing components.

[0008] Optionally, the ridging assembly further includes soil guides, the number of which is equal to the number of the cutter bodies, and the soil guides are disposed on the opposite side of the digging side of the cutter bodies; The angle between the soil guide and the cutter body is an obtuse angle, and the soil guide and the corresponding cutter body are integrally formed.

[0009] Optionally, the soil covering component includes a main board, which is fixedly connected to the fixing frame and located above the ridging component; The main board has at least two bent cover plates on both sides; The adapter connects the main board to the adjacent bent cover plate, and the adjacent bent cover plates are connected through the adapter. The first driving unit is used to synchronously drive and adjust the angle between the bent cover plates on both sides of the motherboard and the motherboard. At least one second driving unit is provided, which is used to synchronously drive and adjust the angle between adjacent bent cover plates on both sides of the motherboard.

[0010] Optionally, the first drive unit includes two flexible connectors, one end of each of the two flexible connectors being connected to the two bent cover plates via connecting lugs; A linear power component is mounted on the fixed frame via a vertical seat. The linear power component synchronously pulls the two flexible connectors through linear telescopic movement to synchronously control the angle between the two bending cover plates and the main board. An elastic element is provided for resetting the bent cover plate to the side facing the ground.

[0011] Optionally, the first driving unit and the second driving unit have the same structure; The number of the second drive units is less than one of the number of the bent cover plates on one side of the motherboard.

[0012] Optionally, the front end of the fixed frame is provided with an extension arm facing left and right, and the two seeding components are respectively detachably mounted on the extension arm by mounting parts, so that the distance between the two seeding components can be adjusted; The mounting component includes a U-shaped buckle, the open side of which is fastened to the extension arm; A fastening connection unit that connects the seeding assembly and the U-shaped buckle to the extension arm.

[0013] Optionally, the ridge-forming seeding mechanism further includes a stabilizing wheel, which is mounted on the front end of the fixed frame via an adjustable mounting bracket; The adjustable mounting bracket includes an adjusting rod and a T-shaped rod. The horizontal part of the T-shaped rod is rotatably connected to the stabilizing wheel at both ends. The adjusting rod is rotatably connected to the protruding seat at the front end of the fixed frame. The downward end of the adjusting rod is provided with an adjusting thread. The vertical part of the T-shaped rod is provided with a blind hole along its own axial direction. An internal thread that mates with the adjusting thread is formed on the inner arm of the blind hole. A channel for the T-shaped rod to move up and down is formed on the protruding seat.

[0014] A method for sowing corn using a walk-behind double-row direct seeding and ridge-forming machine without furrowing, comprising the following steps: Sowing steps: First, the corn seeds are directly sown onto the ground in two rows using the two sowing components suspended in the air; The ridging process involves the power unit driving the machine to move and transmitting power to the two sets of soil-lifting blades. The two sets of soil-lifting blades dig up the soil between the two rows of corn seeds and throw it to both sides to form furrows. The soil is thrown out to cover the seeds sown on the ground by the sowing component and to raise the ridges. Two rows of corn seeds are sown on the ridges between adjacent furrows. Covering with soil step: The first driving unit drives and adjusts the angle between the bent cover plates on both sides of the main board and the main board. The second driving unit simultaneously drives and adjusts the angle between adjacent bent cover plates on both sides of the main board. Through the cooperation of the first driving unit and the second driving unit, the soil thickness covered by the soil dug up and thrown by the two sets of soil-lifting blades on the seeds sown on the ground by the two sowing components can be adjusted.

[0015] As described above, the hand-held corn double-row direct seeding and ridge-forming planter and method of the present invention have at least the following beneficial effects: By simultaneously driving the walking and ridging components with a power component, the power is split, eliminating the need for an additional ridging power source and achieving high integration and miniaturization. This simplifies the equipment structure, reduces the overall weight and manufacturing cost, making it suitable for small plots in hilly and mountainous areas. As the machine moves forward, two seeding components fixed to the left and right sides at the front of the machine suspend corn seeds and sow them directly onto the uncultivated, level land, forming two rows of seed strips. This suspended sowing prevents clogging of the seed pipes during the sowing process. Two sets of soil-lifting blades follow closely behind, rotating and cutting into the soil between the two seed strips, digging up the soil and throwing it to both sides, creating furrows between the seed rows. The thrown soil then covers the two rows of seeds, completing the covering and naturally raising the soil to form ridges. This facilitates drainage and flood prevention, increases soil aeration, and meets the needs of corn growth. The entire process—sowing, ridging, and covering—is integrated into a single, unified operation, enabling continuous sowing, ridging, and covering. The compact and highly integrated structure reduces the number of times the equipment needs to enter the field, lowers operating time and labor costs, and ultimately improves field efficiency. The soil-covering component fine-tunes the thickness of the covering soil to ensure consistent sowing depth. Attached Figure Description

Detailed Implementation

[0018] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0019] Please see Figures 1 to 9It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0020] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0021] In this embodiment, please refer to Figures 1 to 9 This invention provides a hand-held corn double-row direct seeding and ridge-forming planter without furrowing, comprising: The walking mechanism 1 includes a body 11, a power component 12 fixedly mounted on the body 11 for driving the body 11, and a handrail 13 mounted on the body 11. The body 11 serves as the basic load-bearing structure of the entire device, possessing good stability and mobility, ensuring the stable operation of other mechanisms. The right handrail 13 is equipped with a control button connected to the power component 12 via a cable, and the left handrail 13 is equipped with a handbrake. Operators can operate the body 11 through the handrails 13 to perform various actions such as forward, backward, and turning, greatly improving the convenience and flexibility of operation. The power component 12 is an engine, which can be a diesel engine or a gasoline engine, driving the body 11 to move.

[0022] The body 11 is also provided with a tire, which is located below the body 11. The tire is connected to the body 11 via an axle, and the power unit 12 drives the tire to rotate.

[0023] The ridge-forming and sowing mechanism 2 includes a fixed frame 21 fixedly installed in front of the machine body 11, a ridge-forming component 22 rotatably connected to the machine body 11, two sowing components 23 and a soil-covering component 24; The ridging component 22 includes a drive shaft 221 and two sets of soil-lifting blades 222. The drive shaft 221 is driven to rotate by the power component 12 through a combined transmission of belt and sprocket sets. The drive shaft 221 is connected to the power component 12. A drive pulley is installed on the output shaft of the power component 12, and a driven pulley is installed on the intermediate shaft. The belt connects the two. The intermediate shaft is connected to the drive shaft 221 through a sprocket transmission set. The two sets of soil-lifting blades 222 are symmetrically installed at both ends of the drive shaft 221. The changes in the moving speed of the machine body 11 and the rotational speed of the soil-lifting blades 222 are both achieved through a gearbox. Gear shifting is achieved through a manually operated gear shift lever, which is connected to a gear shifting mechanism inside the gearbox. The gearbox has gear sets with different gear ratios. By changing the meshing state of the gears through the gear shifting mechanism, different transmission ratios are achieved, thus achieving the purpose of speed change. Speed ​​change is a known prior art, so it will not be described in detail here.

[0024] The two sowing components 23 are respectively located on the front left and right sides of the fixed frame 21, and the distance between the two sowing components 23 is greater than the distance between the two sets of soil-lifting blades 222. The sowing component 23 can be an electric-driven seed metering device, with the power supply set on the fixed frame 21 and an encoder or radar speed measurement set to realize real-time speed adjustment of electric seed metering, avoiding missed sowing or double sowing. It can adopt existing technology, which will not be described in detail here.

[0025] The seeding assembly may also include a housing 2321, a seed metering turntable 2322, a compression disc 2323, a pressure regulating part 2324, and an elastic balloon 2325. The seed metering turntable 2322 has an annular cavity 232221 inside. The seed metering turntable 2322 is rotatably mounted in the housing 2321 via a drive shaft. The housing 2321 may be made of a transparent material to facilitate observation of seed adsorption. Between the inner wall of the housing 2321 and the outer wall of the seed metering turntable 2322, a compression zone 23211, a seed filling zone 23212, a seed carrying zone 23213, and a seed metering zone 23214 are formed sequentially. The elastic balloon 2325 is in the states of being compressed and de-exhausted, expanded and inhaled, maintaining negative pressure, and compressed and blown in the compression zone 23211, seed filling zone 23212, seed carrying zone 23213, and seed metering zone 23214, respectively.

[0026] Two extrusion discs 2323 are configured, and the two extrusion discs 2323 are rotatably mounted in the annular cavity 232221 through the pressure regulating part 2324 and are arranged opposite to each other. On the opposite sides of the two extrusion discs 2323, pressure-generating protrusions 23231 are symmetrically formed, and the thickness of the pressure-generating protrusions 23231 increases smoothly and continuously from the seed dispensing area 23214 to the seed filling area 23212. The thickness of the pressure-generating protrusions 23231 forms a fan-shaped structure along the circumference of the extrusion discs 2323.

[0027] Multiple elastic balloons 2325 are configured and installed in the annular cavity 232221 and located between the two extrusion discs 2323. The seed metering turntable 2322 has multiple seed suction holes 232222 arranged at equal intervals on the circumferential side wall. The number of elastic balloons 2325 is equal to the number of seed suction holes 232222 and the two are connected in a one-to-one correspondence. The pressure regulating unit 2324 drives the two extrusion discs 2323 to move in opposite directions or in the opposite direction at the same time, so as to adjust the suction force of the two pressure-generating protrusions 23231 on the elastic balloon 2325 when they suck up seeds.

[0028] The drive shaft, driven by a motor, rotates the seed metering turntable 2322. Seed suction holes 232222 enter the seed filling zone 23212. The elastic balloon 2325 corresponding to the seed suction hole 232222 is located between the thicker parts of the pressure-generating bosses 23231 on the two compression discs 2323. The elastic balloon 2325 is compressed. As the seed metering turntable 2322 continues to rotate, the squeezing force on the elastic balloon 2325 by the two pressure-generating bosses 23231 gradually weakens. The elastic balloon 2325 recovers through its own elasticity, increasing its volume and generating negative pressure, which is then released through the seed suction hole 232222. The negative pressure suction adsorbs the seeds onto the seed suction hole 232222, allowing the pressure-generating boss 23231 to compress the seeds and the elastic recovery of the elastic bulb 2325 to generate negative pressure independently. This significantly reduces energy consumption and equipment complexity, thereby lowering costs. The seed suction hole 232222, after adsorbing the seeds, enters the seed carrying area 23213, where the seeds are stably carried. When the seed discharging turntable 2322 rotates to the seed discharging area 23214, the pressure exerted by the pressure-generating boss 23231 on the elastic bulb 2325 gradually increases. At this time, the volume of the elastic bulb 2325 decreases, generating positive pressure and blowing the seeds off. The pressure regulating unit 2324 drives the compression disc 2323 to move in opposite directions, adjusting the overall compression degree of the elastic bulb 2325 to achieve suction adjustment.

[0029] The elastic balloon 2325 includes a connecting tube 23251 and an elastic balloon body 23252. The elastic balloon body 23252 can be made of rubber or thermoplastic elastomer to meet the hardness and elasticity requirements. One end of the connecting tube 23251 is connected to the seed suction hole 232222, and the diameter of the connecting tube 23251 is larger than the diameter of the seed suction hole 232222. This allows air to be drawn in more quickly through the connecting tube 23251 when the elastic balloon body 23252 recovers its deformation, thereby accelerating the establishment of negative pressure and facilitating timely and reliable seed adsorption. The other end of the connecting tube 23251 is connected to the interior of the elastic balloon body 23252. The side of the housing 2321, corresponding to the position of the compression area 23211, has a venting groove for the elastic bladder 23252 to release air when it is compressed by the pressure-generating boss 23231.

[0030] The pressure regulating part 2324 includes an adjusting sleeve 23241. One end of the adjusting sleeve 23241 is located inside the annular cavity 232221 and is sleeved on the seeding turntable 2322 via a bearing 23242. The other end of the adjusting sleeve 23241 extends to the outside of the housing 2321. Two threads of the same length but different directions of rotation are provided on the side wall of one end of the adjusting sleeve 23241. Adjusting screw holes 23232 with different directions of rotation are respectively formed at the axial positions of the two extrusion discs 2323. These threads are threaded to the threads of different directions of rotation on the adjusting sleeve 23241. A fixing plate 23243 is fixedly installed inside the housing 2321 on one side; Guide shaft 23244 is perpendicular to and fixedly connected to the other side wall of fixed disk 23243. The central axis of guide shaft 23244 is parallel to the central axis of adjusting sleeve 23241. Guide shaft 23244 passes through guide holes 23233 on two extrusion disks 2323.

[0031] By rotating the adjusting sleeve 23241 extending outside the housing 2321, the threads on one end of the adjusting sleeve 23241, with different directions of rotation, engage with the adjusting screw holes 23232 at the shaft centers of the two extrusion discs 2323. This converts the rotational motion of the adjusting sleeve 23241 into the linear motion of the extrusion discs 2323. When the sleeve rotates in one direction, the two extrusion discs 2323 move synchronously towards each other, compressing the elastic bladder 23252 in the middle, increasing its deformation, and thus increasing the generated negative pressure. When the sleeve is rotated in the opposite direction, the two extrusion discs 2323 move synchronously away from each other, releasing the pressure on the bladder and reducing the negative pressure. Furthermore, once adjusted to the correct position, the self-locking characteristic of the threads effectively maintains the current position, ensuring stable pressure.

[0032] The pressure-generating protrusion 23231 is located at one end of the high side of the seed filling area 23212 and has a smooth arc surface 232311 to ensure that the negative pressure generation is stable and controllable and improve the reliability of seed absorption.

[0033] The housing 2321 has an inlet 232121 corresponding to the seed filling area 23212, wherein the inlet 232121 is connected to the storage hopper. The inlet 2321211 is provided with an anti-scratching plate 232122. The anti-scratching plate can be an L-shaped structure. The anti-scratching plate 232122 divides the inlet 232121 into a seed storage cavity 2321221 and a seed transport cavity 2321222. The seed transport cavity 2321222 is the gap between the anti-scratching plate and the side wall of the seed dispensing turntable 2322, so as to prevent seeds that are not sucked by the elastic capsule 23252 from entering the seed carrying area 23213. The housing 2321 has a discharge port 232141 corresponding to the seed dispensing area 23214; The squeezing zone 23211 corresponds to a sector angle of 75° with the seed metering turntable 2322, the seed filling zone 23212 corresponds to a sector angle of 75° with the seed metering turntable 2322, the seed carrying zone 23213 corresponds to a sector angle of 150° with the seed metering turntable 2322, and the seed metering zone 23214 corresponds to a sector angle of 60° with the prime number seed metering turntable 2322.

[0034] Two rows of corn seeds are directly sown onto the ground by the two sowing components 23. The power component 12 drives the machine body 11 to move and transmits power to the two soil-lifting blade groups 222. The two soil-lifting blade groups 222 dig up the soil between the two rows of corn seeds and throw it to both sides to form furrows. The soil is thrown out to cover the seeds sown by the sowing components 23 on the ground and to raise the ridges. The soil-covering component 24 is used to adjust the thickness of the soil dug up and thrown by the two soil-lifting blade groups 222 covering the seeds sown by the two sowing components 23 on the ground.

[0035] The power component 12 simultaneously drives the walking and ridging components 22, thus splitting the power flow. This eliminates the need for an additional ridging power source and is highly integrated and miniaturized, simplifying the equipment structure and reducing the overall weight and manufacturing cost, making it suitable for small plots in hilly and mountainous areas. As the machine body 11 moves forward, two sowing components 23 fixed on the left and right sides in front of the machine body 11 suspend corn seeds and sow them directly onto the uncultivated flat land, forming two rows of seed strips. The suspended sowing of seeds avoids clogging of the seed discharge pipe during the sowing process. Two sets of soil-lifting blades 222 follow closely behind, rotating and cutting into the soil between the two rows of seed strips, digging up the soil and throwing it to both sides, creating furrows between the seed rows. The thrown soil then covers the two rows of seeds that have just been sown, completing the soil covering and naturally piling up to form ridges. This facilitates drainage and flood prevention, increases soil aeration, and adapts to the growth needs of corn. The sowing, ridging, and soil covering are integrated into a single process, achieving continuous operation of sowing, ridging, and soil covering. The compact structure and high integration reduce the number of times the equipment enters the field, reduce operating time and labor costs, and thus improve field operation efficiency. The soil covering component 24 finely adjusts the thickness of the covered soil to ensure consistent sowing depth.

[0036] In this embodiment, please refer to Figures 1 to 3 The soil-lifting blade assembly 222 includes several blades 2221 arranged spirally along the axial direction of the drive shaft 221. This spiral arrangement allows the blades 2221 to sequentially cut into the soil at different phase angles as the drive shaft 221 rotates, resulting in continuous and stable operation, uniform power load, and a pushing force generated along the axial direction that pushes the soil from the center to both sides. This ensures even soil coverage over the seeds, regular ridging formation, and facilitates the breaking up of soil clods, resulting in finer soil after ridging, which is beneficial for seed germination.

[0037] The ridging component 22 also includes a bottom blade 223, which is mounted on the fixed frame 21 and located between the two sets of soil-lifting blades 222, which helps to optimize the quality of the furrows.

[0038] In this embodiment, please refer to Figure 3 The blade body 2221 includes an arc-shaped segment 22211, which is detachably mounted on a mounting base 22215 via at least one fastening part 22214. The mounting base 22215 is fixedly connected to the side wall of the drive shaft 221. The fastening part 22214 includes a connector and a fastener. The mounting base 22215 has a slot for inserting the arc-shaped segment 22211 in a direction perpendicular to the central axis of the drive shaft 221. At least one through hole is formed on the mounting base 22215 and the arc-shaped segment 22211 for the connector to pass through, and the central axis of the through hole is parallel to the central axis of the drive shaft 221. The fastener is used to engage with one end of the connector after the connector passes through the through hole on the mounting base 22215 and the arc-shaped segment 22211. The connector can be a bolt, in which case the fastener is a nut; the connector can also be a U-bolt, in which case the locking part has two nuts and can be detachably connected, which improves the convenience of maintenance and replacement. The bent section 22212 has one end fixedly connected to the arc-shaped section 22211, and the bending direction of the bent section 22212 is towards the side of the seeding component 23. An inclined segment 22213 is fixedly connected to the other end of the bent segment 22212. The arc segment 22211, the bent segment 22212, and the inclined segment 22213 can be integrally formed, thereby improving rigidity.

[0039] The cutter body 2221 is detachably mounted on the drive shaft 221 via the fastening part 22214 on the arc-shaped section 22211, which simplifies the replacement and maintenance process of the cutter body 2221. When the cutter body 2221 is worn or damaged, it is not necessary to disassemble the entire cutter shaft, and the individual cutter body 2221 can be directly replaced, reducing maintenance costs and time.

[0040] In this embodiment, the ridging component 22 further includes soil guides, the number of which is equal to that of the cutter body 2221. The soil guides are disposed on the opposite side of the digging side of the cutter body 2221. The soil guides can be guide plates with a shape similar to that of the cutter body 2221.

[0041] The angle between the soil guide and the blade 2221 is obtuse, and the soil guide and the corresponding blade 2221 are integrally formed. When the machine body 11 moves forward, the high-speed rotating blade 2221 cuts into the soil from below, crushes and throws it up, and the rotating soil guide can carry more soil up and guide it to both sides, improving the quality of soil raising and ridging.

[0042] In this embodiment, please refer to Figures 1 to 4 The soil covering component 24 includes a main board 241, which is fixedly connected to the fixed frame 21 and located above the ridging component 22. The main board 241 has at least two bending cover plates 242 on both sides; the bending cover plate on one side of the main board can initially be set in an arc shape.

[0043] The adapter 243 connects the main board 241 and the adjacent bending cover plate 242. The adapter 243 includes a protruding block, a concave block, and a shaft core. The protruding block is installed on the edge of the main board 241 or the bending cover plate 242, and the concave block is installed on the bending cover plate 242 or the main board 241. Both the protruding block and the concave block have shaft holes for the shaft core to pass through and be movably connected.

[0044] The first driving unit 244 is used to synchronously drive and adjust the angle between the bent cover plate 242 on both sides of the motherboard 241 and the motherboard 241. At least one second driving unit 245 is provided for synchronously driving and adjusting the angle between adjacent bent cover plates 242 on both sides of the motherboard 241.

[0045] The first drive unit 244 and the second drive unit 245 drive the bending cover plates 242 on both sides of the main board 241 and the bending cover plates 242 together, causing the bending cover plates 242 to retract inward or open. This adjusts the soil thickness covering the seeds sown on the ground by the sowing component 23 and the shape of the ridge surface, creating a suitable compacted or loose seedbed environment for seed germination. The soil thrown up and falling can also make close contact with the corn seeds due to its own gravity, ensuring normal seed growth. The soil covering component 24, while adjusting the soil thickness, also ensures that the corn seeds are at the same sowing depth.

[0046] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The first drive unit 244 includes two flexible connectors 2411, one end of each of the two flexible connectors 2411 being connected to the two bent cover plates 242 via connecting lugs 2412; the flexible connectors 2411 can be traction cables made of polymer materials, or plastic-coated steel wire ropes made of weather-resistant and wear-resistant materials.

[0047] A linear power component 2443 is mounted on the fixed frame 21 via a vertical seat 2444. The linear power component 2443 synchronously pulls the two flexible connectors 2411 through linear telescopic movement to synchronously control the angle between the two bending cover plates 242 and the main board 241. The linear power component 2443 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0048] The elastic element 2445 is used to return the bent cover plate 242 to the ground-facing side. The elastic element 2445 can be a torsion spring, which is mounted on the main board 241 or the bent cover plate 242 via mounting lugs to return the bent cover plate 242 to the ground-facing side. The mounting lugs have through holes for flexible connectors to pass through, making the wiring more reasonable and reducing space occupation.

[0049] The linear power component 2443 drives two flexible connectors 2411 to simultaneously pull the bent cover plates 242 on both sides, enabling the angles on both sides to be controlled synchronously by a single power source. The structure is simple, the cost is low, and it can effectively ensure the consistency of the actions on both sides. In cooperation with the elastic component 2445, it can automatically reset the bent cover plates 242 and also play a role in energy absorption and buffering, thus extending the service life.

[0050] In this embodiment, please refer to Figure 2 The first driving unit 244 and the second driving unit 245 have the same structure; The number of second drive units 245 is less than one of the number of bent cover plates 242 on one side of the motherboard 241. When there are two bent cover plates 242 on one side of the motherboard 241, the number of second drive units 245 is one.

[0051] In this embodiment, please refer to Figure 1 and Figure 2 The fixed frame 21 has an extension arm 211 facing left and right at its front end. The two seeding components 23 are respectively detachably mounted on the extension arm 211 via mounting parts 231, so that the distance between the two seeding components 23 can be adjusted. The mounting component 231 includes a U-shaped buckle 2311, the open side of which is fastened to the extension arm 211; A fastening connection unit 2312 connects the seeding assembly 23 and the U-shaped buckle 2311 to the extension arm 211. The fastening connection unit 2312 includes a connecting element and a fastening element. The connecting element is configured to pass through openings in the housings of the U-shaped buckle 2311 and the seeding assembly 23, and engages with the fastening element to achieve clamping and fixation. When the connecting element and the fastening element engage, a preset clamping force is generated between the U-shaped buckle 2311 and the seeding assembly 23, thereby achieving fixation. The connecting element and the fastening element can be bolts and nuts.

[0052] In this embodiment, please refer to Figure 1 The ridge-forming sowing mechanism 2 also includes a stabilizing wheel 25, which is mounted on the front end of the fixed frame 21 via an adjustable mounting bracket 251; The adjustable mounting bracket 251 includes an adjusting rod 2511 and a T-shaped rod 2512. The horizontal ends of the T-shaped rod 2512 are rotatably connected to the stabilizing wheel 25. The adjusting rod 2511 is rotatably connected to the protruding seat at the front end of the fixed frame 21. The adjusting rod 2511 has an adjusting thread at the downward end and a handwheel at the other end for easy and effortless adjustment of the height of the stabilizing wheel 25. The vertical end of the T-shaped rod 2512 has a blind hole along its own axial direction. An internal thread that mates with the adjusting thread is formed on the inner arm of the blind hole. The protruding seat has a channel for the T-shaped rod 2512 to move up and down. The protruding seat is square, and the vertical part of the T-shaped rod 2512 and the channel are also square. By rotating the handwheel to rotate the adjusting rod 2511, the adjusting rod 2511 and the internal thread in the blind hole of the vertical part of the T-shaped rod 2512 are threadedly engaged, so that the T-shaped rod 2512 moves up and down along the channel on the protruding seat, thereby achieving stable contact between the stabilizing wheel 25 and the ground to share the weight of the machine body 11, which helps to reduce traction power consumption.

[0053] In another embodiment, please refer to Figure 5 The seeder also includes two balancing mechanisms 3, which are detachably installed on the left and right sides of the machine body 11 respectively. In actual use, the two balancing mechanisms 3 are located outside the corn seeds sown by the seeding component 23, and the distance between the two balancing mechanisms 3 is greater than the distance between two rows of corn seeds. The balancing mechanism 3 includes a mounting frame 31, with a hanging arm 32 on one side and a roller 33 that rolls in contact with the ground on the other side. The suspension arm 34 is fixedly connected to one side of the machine body 11. The suspension arm 34 has multiple suspension holes 341 along its own height direction, so that the height can be adjusted according to the depth of the furrow. At least two fixed connection assemblies are provided for detachably connecting the mounting arm 32 to the suspension arm 34. Each fixed connection assembly includes a fastener and a fixing member. The fastener is configured to pass through a suspension hole 341 on the suspension arm 34 and an opening on the mounting arm 32, and engages with the fixing member for fixation. When the fastener engages with the fixing member, a preset clamping force is generated between the mounting arm 32 and the suspension arm 34, thereby achieving fixation. The fastener can be a bolt, in which case the fixing member is a nut; the fastener can also be a U-bolt, in which case the fixing member has two nuts, allowing for detachable connection and improving the ease of maintenance and replacement. The balancing body 35 has a receiving cavity on the mounting frame 31 for accommodating it. The balancing body 35 can be a counterweight bucket, which can be filled with water, sand, or iron blocks.

[0054] By symmetrically installing balancing mechanisms 3 on the left and right sides of the machine body 11, the lateral support span of the machine body 11 is increased, which can effectively resist the lateral tilting moment generated by the uneven ground and uneven resistance on one side of the tires during sowing operations, prevent the machine from swaying left and right, and improve the stability of driving and operation.

[0055] In another embodiment, the balancing mechanism 3 further includes a conduit 36, and the balancing body 35 has a liquid storage chamber 351 inside, the liquid storage chamber 351 is used to hold water, and the conduit 36 ​​is connected to the liquid storage chamber 351. The liquid outlet assembly 37 is equipped with multiple outlets 371 facing the direction of the corn seeds being directly sown by the sowing assembly 23. The high-speed solenoid valve and suction pump can be wirelessly controlled via a control unit on the handle 13. Through the conduit 36 ​​and the liquid outlet assembly 37, water can be applied to the freshly sown corn seeds simultaneously with sowing, achieving integrated sowing and hydration, reducing the number of separate operations, improving efficiency, and meeting the needs of different soil moisture conditions to increase germination rate and uniformity.

[0056] The liquid outlet component 37 is an annular pipe, and all the liquid outlets 371 are formed on the downward side of the annular pipe. The annular pipe surrounds the sowing point, and the multiple liquid outlets 371 on its downward side can apply liquid to the soil around the seed in a 360-degree or nearly circumferential direction, which helps to more evenly moisten the seed bed around the seed, forming a moist microenvironment that is conducive to the seed absorbing water and germinating in all directions.

[0057] Alternatively, the liquid outlet assembly 37 is a U-shaped pipe with the opening facing the direction of travel of the body 11. Multiple liquid outlets 371 are formed in a linear array on both sides of the opening of the U-shaped pipe. The liquid outlet direction of the liquid outlet 371 is inclined relative to the vertical direction, and the inclination direction of the liquid outlets 371 corresponding to two opposite liquid outlets 371 is opposite.

[0058] In this embodiment, please refer to Figures 1 to 9 A method for sowing corn using a walk-behind double-row direct seeding and ridge-forming machine without furrowing, comprising the following steps: Sowing steps: First, the corn seeds are suspended in the air and sown directly onto the ground through the two sowing components 23 to form two rows; The ridging process involves driving the machine body 11 through the power component 12 and transmitting power to the two sets of soil-lifting blades 222. The two sets of soil-lifting blades 222 dig up the soil between the two rows of corn seeds and throw it to both sides to form furrows. The soil is thrown out to cover the seeds sown on the ground by the sowing component 23 and to raise the ridges. Two rows of corn seeds are sown on the ridges between adjacent furrows. Covering with soil: The first driving unit 244 drives and adjusts the angle between the bent cover plates 242 on both sides of the main board 241 and the main board. The second driving unit 245 simultaneously drives and adjusts the angle between the adjacent bent cover plates 242 on both sides of the main board 241. Through the cooperation of the first driving unit 244 and the second driving unit 245, the thickness of the soil covered by the soil dug up and thrown by the two sets of soil-lifting blades 222 on the seeds sown on the ground by the two sowing components 23 can be adjusted.

[0059] In summary, the present invention achieves power diversion by simultaneously driving the walking and ridging components 22 through the power component 12, eliminating the need for an additional ridging power source and achieving high integration and miniaturization, simplifying the equipment structure, reducing the overall weight and manufacturing cost, and thus making it suitable for small plots in hilly and mountainous areas. As the machine body 11 moves forward, two sowing components 23 fixed on the left and right sides in front of the machine body 11 suspend corn seeds and sow them directly onto the uncultivated flat land, forming two rows of seed strips. The suspended sowing prevents clogging of the seed discharge pipe during the sowing process. Two sets of soil-lifting blades 222 follow closely behind, rotating and cutting into the soil between the two rows of seed strips, digging up the soil and throwing it to both sides, creating furrows between the seed rows. The thrown soil then covers the two rows of seeds, completing the covering and naturally raising the soil to form ridges. This facilitates drainage and flood prevention, increases soil aeration, and meets the needs of corn growth. The sowing, ridging, and covering processes are integrated into a single process, achieving continuous operation. The compact structure and high integration reduce the number of times the equipment needs to enter the field, lowering operating time and labor costs, thereby improving field operation efficiency. The soil-covering component 24 fine-tunes the thickness of the covered soil to ensure consistent sowing depth. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0060] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
