Abstract
Description
Technical Field
[0001] This invention relates to the field of corn planting technology, specifically to a corn planter with adjustable spacing. Background Technology
[0002] Corn ranks third in planting area among grain crops, after rice and wheat. With the gradual development of society, agricultural production increasingly relies on agricultural machinery. A corn planter is a planting machine that sows corn seeds. Planters are often named after the crop, such as corn planter, grain row planter, corn hill planter, cotton planter, and pasture spreader. Corn planters are characterized by uniform sowing depth, stable row spacing, good soil covering, seed saving, and high work efficiency.
[0003] Chinese patent CN221829436U discloses a corn planter with adjustable spacing, which can improve the ease of equipment movement, but cannot achieve rapid spacing adjustment, inconvenient seed storage, or reduce the blockage of seed delivery pipes. Summary of the Invention
[0004] To address the aforementioned problems, the present invention provides the following technical solution: a corn planter with adjustable spacing, comprising a support frame for supporting and bearing the load of equipment components. A support rod is fixedly connected to one side of the top of the support frame, and a stabilizing component is slidably connected to the outer side of the support rod to provide shock absorption and buffering, reducing vibrations generated by the mixing of the feeding components and minimizing the amplitude of vibrations during equipment movement, thereby improving the stability of the equipment operation. A foot assembly is fixedly connected to the bottom side of the stabilizing component away from the support rod to roll the covering soil. This improves the contact density between seeds and soil, reduces soil porosity, minimizes water loss to the air, and reduces soil moisture evaporation. It also prevents seeds from shifting due to water flow or soil movement during rainfall, irrigation, or field work after sowing, stabilizing the sowing depth. Rolling ensures a more uniform soil thickness within the seed furrow, preventing fluctuations in actual sowing depth caused by loose soil and ensuring consistent seedling emergence. A feeding component is fixedly connected to the inner side of the stabilizing component for storing corn seeds, facilitating subsequent seed feeding and enabling continuous equipment operation, thus improving equipment efficiency. The feeding component agitates the corn seeds inside, reducing material adhesion or sticking, thus avoiding impact on planting quality and minimizing resource waste. A seed metering device, employing a pneumatic suction type, is fixedly connected to the bottom of the feeding component for convenient quantitative seed dispensing, ensuring the equipment's operational quality. A conveying pipe is fixedly connected to the outside of the seed metering device, allowing seeds to move from the seed metering device to the conveying pipe for sowing. A pneumatic component is fixedly connected to the outside of the conveying pipe. A hydraulic rod is fixedly connected to the bottom of the stabilizing assembly, controlling the lifting of the irregularly shaped housing to facilitate stabilization. The components slide on the support rod to adjust the position of the equipment, thereby adjusting the sowing spacing. The bottom of the hydraulic rod is fixedly connected to an irregularly shaped shell. When the mobile carrier moves the equipment, the irregularly shaped blocks at the bottom of the shell cultivate the soil. A bulldozer is fixedly connected to one side of the shell, with a structure that is wider on the outside and narrower on the inside. Through rotational friction with the soil, it pushes the soil to accumulate, thereby covering the seeds. A buckle is fixedly connected to one side of the support bracket, which connects to the mobile carrier, facilitating the movement of the equipment by the mobile carrier. The tripod assembly includes a connecting end, with a tripod bracket hinged to the inner side of the connecting end. A roller is rotatably connected to the side of the tripod bracket away from the connecting end. A first electric push rod controls the extension and retraction of the tripod bracket. This raises the component, reducing friction with the ground and facilitating subsequent adjustments to its position. Furthermore, the extension and retraction controls the contact distance between the roller and the soil, adjusting the rolling pressure. This rolling process ensures a more uniform soil thickness in the planting furrow, preventing fluctuations in actual sowing depth due to loose soil and ensuring consistent corn seedling emergence time. A first electric push rod is fixedly connected between opposite outer surfaces of the tripod bracket.
[0005] Preferably, the stabilizing component includes a sliding block, with a ring-shaped base fixedly connected to the inner side of the sliding block. A telescopic rod is fixedly connected to the top of the ring-shaped base. The telescopic rod compresses and contracts the spring strip, thereby playing a role in shock absorption and buffering. On the one hand, it reduces the amplitude of the component itself, avoiding affecting the mixing effect of the equipment; on the other hand, it reduces the vibration caused by external pressure, avoiding external vibration affecting the internal operation of the equipment. This reduces the shaking effect of the equipment and improves the stability of the equipment operation. A spring strip is sleeved on the outer side of the telescopic rod, and a ring-shaped top block is fixedly connected to the top of the telescopic rod.
[0006] Preferably, the feeding component includes a feeding housing, with a receiving end fixedly connected to the top of the feeding housing. A cover plate is snapped onto the inner side of the receiving end, and pulling the cover plate facilitates disassembly and installation on the receiving end, making subsequent cleaning of the equipment interior convenient. A motor is fixedly connected to the top of the cover plate, and the motor controls the rotation of the connecting shaft. The connecting shaft drives the stirring component to stir the corn seeds, thereby breaking up seed clumps, preventing conveying blockages, avoiding localized empty material, ensuring uniform seed supply, reducing seed bridging, and maintaining continuous seed supply. A connecting shaft is fixedly connected to the output end of the motor, and a stirring component is fixedly connected to the outer side of the connecting shaft. A friction component is fixedly connected to the bottom of the inner wall of the feeding housing. The rotation of the connecting shaft drives the friction component to rotate, causing the friction component to rub against the inner wall of the housing, thereby reducing seed residue, facilitating cleaning, reducing seed adhesion, and reducing resource waste. A control valve is fixedly connected to the middle of the bottom of the feeding housing to control seed discharge and reduce the entry of external impurities, preventing seed contamination. A feed pipe is fixedly connected to the upper side of the outer side of the feeding housing.
[0007] Preferably, the mixing assembly includes a connecting column, and a mixing bracket is fixedly connected to the outside of the connecting column. The mixing bracket controls the mixing plate to mix the corn seeds, thereby breaking up seed clumps, preventing conveying blockages, avoiding local empty material, ensuring uniform seed supply, reducing seed bridging, maintaining continuous seed supply, preventing the equipment from being too wet and causing seeds to stick together, and preventing the equipment's operating efficiency from being affected. A mixing plate is fixedly connected to one side of the outside of the mixing bracket.
[0008] Preferably, a silicone pad is fixedly connected to the side of the mixing plate away from the mixing support. The silicone pad is made of silicone material and has a certain degree of wear resistance, thereby reducing wear between the components and the seeds, avoiding damage to the seeds, preventing seed sowing quality issues, and avoiding affecting seed germination. An arc-shaped groove is formed on the side of the silicone pad away from the mixing plate to enhance the deformation performance of the components, further improve the buffering effect of the components, reduce the kinetic energy between the materials and the components, and play a certain protective role for the seeds.
[0009] Preferably, the friction assembly includes a fixed frame, with a rotating shaft rotatably connected to the inner side of the fixed frame. A second electric push rod is fixedly connected to the top of the rotating shaft. The second electric push rod can be raised and lowered to align with the bottom of the connecting shaft, thus facilitating rotation with the connecting shaft. A scraper bracket is fixedly connected to the outer side of the second electric push rod. By rotating, the scraper bracket controls the scraper plate to rub against the inner wall of the housing, thereby reducing seed residue, facilitating cleaning, reducing seed adhesion, reducing resource waste, preventing seeds from corroding and contaminating the equipment due to prolonged lack of cleaning, and preventing contamination of other corn seeds. A scraper plate is fixedly connected to one side of the outer side of the scraper bracket.
[0010] Preferably, the pneumatic component includes a first interface through which air is supplied to the inside of the delivery pipe. On the one hand, the air force washes over the inner wall of the pipe, thereby cleaning impurities and preventing excessive accumulation of impurities that could cause blockage. On the other hand, the air force washes away any seeds that may be attached, reducing the difficulty of cleaning the equipment. A first pipe is fixedly connected to one side of the first interface. A grid plate is fixedly connected to the inner wall of the first pipe near the first interface to prevent external impurities from entering. A cleaning component is fixedly connected to the inner side of the first pipe. The cleaning component rubs against the grid plate to remove impurities through friction, preventing soil and dust from clogging the holes and hindering airflow. A first fan is fixedly connected to the outer side of the first pipe away from the grid plate.
[0011] Preferably, a connecting frame is fixedly connected to the top of the first interface, and a second interface is fixedly connected to the side of the connecting frame away from the first interface. A second pipe is fixedly connected to the side of the second interface. A second fan supplies air into the second interface, and the airflow flushes from the top of the delivery pipe, further improving the cleaning efficiency of the pipe. A second fan is fixedly connected to the side of the second pipe away from the second interface. The first fan and the second fan use alternating airflow to keep the inner wall of the pipe clean. The bidirectional flushing breaks down impurities and deposits, cleans without dead corners, covers the entire area of the pipe wall, extends the service life of the seed delivery pipe, and reduces maintenance costs.
[0012] Preferably, the cleaning assembly includes a cleaning frame. A receiving shaft is fixedly connected to one side of the outer side of the cleaning frame. An outer column is rotatably connected to the outer side of the receiving shaft. A paddle is fixedly connected to one side of the outer column. The paddle drives the outer column to rotate, causing the square frame to control the friction column to rub against the surface of the grid plate, thereby cleaning impurities through friction, removing stubborn adhering impurities, preventing clogging of the grid holes, breaking up impurity clumps, restoring the screening function, cleaning without dead angles, and covering the entire area of the grid. A square frame is fixedly connected to the outer side of the outer column away from the paddle. A friction column is rotatably connected to the inner side of the square frame. A rubber block is fixedly connected to the outer side of the friction column. The rubber block is made of rubber and provides protection for the components during friction, reducing wear on the grid plate, extending its service life, and reducing wear between components. The outer side of the rubber block has a surface cut to enhance the deformation performance of the component and further improve the working effect of the component.
[0013] This invention provides a corn planter with adjustable spacing. It has the following beneficial effects: I. This adjustable-spacing corn planter, through its stabilizing component design, uses a telescopic rod to compress and shrink the spring strip when the internal mixing of the feeding components or the movement of the equipment causes vibration. This serves to reduce vibration and buffer the impact. On the one hand, it reduces the amplitude of the components themselves, preventing them from affecting the mixing effect of the equipment. On the other hand, it reduces the vibration caused by external pressure, preventing external vibration from affecting the internal operation of the equipment. This reduces the shaking effect of the equipment and improves the stability of the equipment operation.
[0014] II. This adjustable-spacing corn planter features a feeding component design. Pulling the cover plate facilitates easy disassembly and installation at the receiving end, simplifying subsequent internal cleaning. The cover plate drives the connecting shaft to connect with the friction assembly. The motor controls the rotation of the connecting shaft, which in turn drives the mixing assembly to agitate the corn seeds. This breaks up seed clumps, prevents conveying blockages, avoids localized empty feed, ensures uniform seed supply, reduces seed bridging, and maintains continuous seed supply. The control valve controls seed discharge and reduces the ingress of external impurities, preventing seed contamination. The feed pipe feeds the seeds, and the rotation of the connecting shaft drives the friction assembly to rub against the inner wall of the casing, reducing seed residue, facilitating cleaning, minimizing seed adhesion, and reducing resource waste.
[0015] Third, this adjustable-spacing corn planter, through the design of a friction component, has a rotating shaft that rotates inside the fixed frame to support the second electric push rod. The second electric push rod can be raised and lowered to align with the bottom of the connecting shaft, thus facilitating rotation with the connecting shaft. This rotation causes the scraper bracket to control the scraper plate to rub against the inner wall of the casing, thereby reducing seed residue, facilitating cleaning, reducing seed adhesion, reducing resource waste, preventing seeds from decaying and contaminating the equipment due to prolonged lack of cleaning, and also preventing contamination of other corn seeds.
[0016] IV. This adjustable-spacing corn planter, through its pneumatic component design, uses a first fan to generate airflow, which is then delivered into the conveying pipe through the first interface. This airflow serves two purposes: firstly, it flushes the inner wall of the pipe, cleaning impurities and preventing blockages caused by excessive accumulation; secondly, it washes away any seeds that may be attached, reducing the difficulty of cleaning the equipment. The second grid plate acts as a barrier to prevent external impurities from entering. The airflow acts on the cleaning components, which rub against the grid plate to remove impurities, preventing soil dust from clogging the holes and ensuring smooth airflow.
[0017] V. This adjustable-spacing corn planter features a cleaning component design. Wind power acts on the paddles, which rotate the external columns, causing the square frame to control the friction columns to rub against the surface of the grating. This friction cleans impurities, removing stubborn, adhered impurities to prevent clogging of the grating holes, breaking up accumulated impurities, restoring the screening function, and providing thorough cleaning covering the entire grating area. The rubber blocks are made of rubber to protect the components during friction, reducing grating wear, extending service life, and minimizing wear between components. The cuts on the blocks enhance the deformation performance of the components, further improving their operational efficiency. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] First embodiment, such as Figures 1 to 3As shown, the present invention provides a technical solution: a corn planter with adjustable spacing, including a support bracket 1, a support rod 2 fixedly connected to one side of the top of the support bracket 1, a stabilizing component 4 slidably connected to the outer side of the support rod 2, a foot assembly 3 fixedly connected to the bottom side of the stabilizing component 4 away from the support rod 2, a feeding component 5 fixedly connected to the inner side of the stabilizing component 4, a seed metering device 6 fixedly connected to the bottom of the feeding component 5, a conveying pipe 7 fixedly connected to the outer side of the seed metering device 6, a pneumatic component 8 fixedly connected to the outer side of the conveying pipe 7, a hydraulic rod 10 fixedly connected to the bottom of the stabilizing component 4, and a shaped shell fixedly connected to the bottom of the hydraulic rod 10. The body 9, with a bulldozer 11 fixedly connected to one side of its outer shell, and a buckle 12 fixedly connected to one side of its outer support bracket 1; the support bracket 1 is used to support and bear the load of the equipment components, and is connected to the mobile carrier through the buckle 12, facilitating the mobile carrier to move the equipment for operation. The feeding component 5 is used to store corn seeds, which facilitates subsequent feeding of seeds, thereby facilitating continuous operation of the equipment and improving its operating efficiency. Secondly, the feeding component 5 stirs the corn seeds inside, thereby reducing material adhesion or sticking, avoiding affecting planting quality, and reducing resource waste. The bottom of the feeding component 5 is connected to a seed metering device 6 for seed metering. The device 6 employs an air-suction seed metering device to facilitate subsequent quantitative seed collection and ensure the quality of equipment operation. Seeds move from the seed metering device 6 to the conveying pipe 7, thus achieving the sowing effect. When the moving carrier moves the equipment, the irregularly shaped blocks at the bottom of the irregularly shaped shell 9 open up the soil, and the seeds enter the soil from the conveying pipe 7. The bulldozer 11 adopts an outer-wide and inner-narrow structure, and pushes the soil to accumulate through rotational friction with the soil, thus covering the seeds. Then, the foot assembly 3 rolls the covered soil to increase the contact density between the seeds and the soil, reduce soil porosity, reduce water loss to the air, and reduce soil moisture. Evaporation prevents seeds from shifting due to water flow or soil movement during rainfall, irrigation, or field operations after sowing, stabilizing the sowing depth. Rolling ensures a more uniform soil thickness in the seed furrow, preventing fluctuations in actual sowing depth caused by loose soil and ensuring consistent emergence time for corn seedlings. The stabilizing component 4 acts as a shock absorber, reducing vibrations generated by the mixing of the feeding component 5 and minimizing amplitude during equipment movement, thus improving the stability of equipment operation. The hydraulic rod 10 controls the lifting of the irregularly shaped housing 9, facilitating the sliding of the stabilizing component 4 on the support rod 2, thereby adjusting the equipment position and thus regulating the sowing spacing.
[0022] The tripod assembly 3 includes a connecting end 31, with a tripod bracket 32 hinged to the inner side of the connecting end 31. A roller 34 is rotatably connected to the inner side of the tripod bracket 32 away from the connecting end 31. A first electric push rod 33 is fixedly connected between the opposite outer surfaces of the tripod bracket 32. The first electric push rod 33 controls the extension and retraction of the tripod bracket 32. This raises the component, reducing friction with the ground and facilitating subsequent adjustments to its position. Furthermore, the extension and retraction controls the contact distance between the roller 34 and the soil, thus adjusting the rolling pressure. This rolling ensures a more uniform soil thickness in the planting furrow, preventing fluctuations in actual sowing depth due to loose soil and ensuring consistent emergence time for corn seedlings.
[0023] The stabilizing component 4 includes a sliding block 42, with a ring-shaped base 41 fixedly connected to the inner side of the sliding block 42. A telescopic rod 43 is fixedly connected to the top of the ring-shaped base 41, and a spring strip 44 is sleeved on the outer side of the telescopic rod 43. A ring-shaped top block 45 is fixedly connected to the top of the telescopic rod 43. When the feeding component 5 vibrates due to internal mixing or equipment movement, the telescopic rod 43 compresses and contracts the spring strip 44, thereby reducing vibration and buffering. This reduces the amplitude of the component itself, preventing it from affecting the mixing effect of the equipment, and also reduces vibration caused by external pressure, preventing external vibration from affecting the internal operation of the equipment. This reduces the shaking effect of the equipment and improves the stability of the equipment operation.
[0024] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 4 to 6 As shown, the feeding component 5 includes a feeding housing 51, a receiving end 52 fixedly connected to the top of the feeding housing 51, a cover plate 53 snapped onto the inner side of the receiving end 52, a motor 54 fixedly connected to the top of the cover plate 53, a connecting shaft 56 fixedly connected to the output end of the motor 54, a stirring assembly 57 fixedly connected to the outer side of the connecting shaft 56, a friction assembly 58 fixedly connected to the bottom of the inner wall of the feeding housing 51, a control valve 59 fixedly connected to the middle of the bottom of the feeding housing 51, and a feed pipe 55 fixedly connected to the upper side of the outer side of the feeding housing 51. Pulling the cover plate 53 facilitates disassembly and installation on the receiving end 52, making subsequent internal cleaning of the equipment easier. The cover plate 53 drives the connecting shaft 56 to connect with the friction component 58. The motor 54 controls the rotation of the connecting shaft 56, which in turn drives the stirring component 57 to stir the corn seeds, thereby breaking up seed clumps, preventing conveying blockages, avoiding localized empty material, ensuring uniform seed supply, reducing seed bridging, and maintaining continuous seed supply. The control valve 59 controls seed discharge and reduces the entry of external impurities to prevent seed contamination. The feed pipe 55 serves as the feed pipe. The rotation of the connecting shaft 56 drives the friction component 58 to rotate, causing the friction component 58 to rub against the inner wall of the shell, thereby reducing seed residue, facilitating cleaning, reducing seed adhesion, and reducing resource waste.
[0025] The mixing assembly 57 includes a connecting column 571, with a mixing bracket 572 fixedly connected to the outer side of the connecting column 571. A mixing plate 573 is fixedly connected to one side of the outer side of the mixing bracket 572. By rotating the connecting shaft 56, the mixing bracket 572 controls the mixing plate 573 to mix the corn seeds, thereby breaking up seed clumps, preventing conveying blockages, avoiding localized empty material, ensuring uniform seed supply, reducing seed bridging, maintaining continuous seed supply, preventing excessive moisture in the equipment that could cause seed adhesion, and preventing any impact on equipment operating efficiency.
[0026] A silicone pad 574 is fixedly connected to the side of the mixing plate 573 away from the mixing support 572. An arc-shaped groove 575 is formed on the side of the silicone pad 574 away from the mixing plate 573. The silicone pad 574 is made of silicone, which has a certain degree of wear resistance, thereby reducing wear between the components and the seeds, preventing damage to the seeds, ensuring seed sowing quality, and avoiding affecting seed germination. The arc-shaped groove 575 enhances the deformation performance of the components, further improving the buffering effect, reducing the kinetic energy between the materials and the components, and providing a certain degree of protection for the seeds.
[0027] The friction assembly 58 includes a fixed frame 581. A rotating shaft 585 is rotatably connected to the inner side of the fixed frame 581. A second electric push rod 582 is fixedly connected to the top of the rotating shaft 585. A scraper bracket 583 is fixedly connected to the outer side of the second electric push rod 582. A scraper plate 584 is fixedly connected to one side of the outer side of the scraper bracket 583. The rotating shaft 585 rotates inside the fixed frame 581, supporting the second electric push rod 582. The second electric push rod 582 can be raised and lowered to engage with the bottom of the connecting shaft 56, thus facilitating rotation with the connecting shaft 56. Through rotation, the scraper bracket 583 controls the scraper plate 584 to rub against the inner wall of the housing, thereby reducing seed residue, facilitating cleaning, reducing seed adhesion, reducing resource waste, preventing seeds from corroding and contaminating the equipment due to prolonged lack of cleaning, and preventing contamination of other corn seeds.
[0028] The third embodiment is based on embodiments one and two; please refer to [link / reference].

The first fan 84 generates airflow, which is delivered into the conveying pipe 7 through the first interface 81. On one hand, the airflow flushes the inner wall of the pipe, cleaning impurities and preventing excessive accumulation that could clog the pipe. On the other hand, the airflow also washes away any seeds that may be attached, reducing the difficulty of cleaning the equipment. The second grid plate 83 prevents external impurities from entering. The airflow acts on the cleaning component 85, which rubs against the grid plate 83, thus cleaning impurities through friction and preventing soil and dust from clogging the holes and hindering airflow.
[0029] A connecting bracket 86 is fixedly connected to the top of the first interface 81. A second interface 87 is fixedly connected to the side of the connecting bracket 86 away from the first interface 81. A second pipe 88 is fixedly connected to the side of the second interface 87. A second fan 89 is fixedly connected to the side of the second pipe 88 away from the second interface 87. The second fan 89 supplies air into the second interface 87. The airflow flushes from the top of the delivery pipe 7, further improving the cleaning efficiency of the pipe. The first fan 84 and the second fan 89 use alternating airflow to keep the inner wall of the pipe clean. The bidirectional flushing breaks down impurities and deposits, cleans without dead corners, covers the entire area of the pipe wall, extends the service life of the seed delivery pipe, and reduces maintenance costs.
[0030] The cleaning component 85 includes a cleaning frame 851. A receiving shaft 852 is fixedly connected to one side of the cleaning frame 851. An external column 853 is rotatably connected to the outside of the receiving shaft 852. A paddle 854 is fixedly connected to one side of the outside of the external column 853. A square frame 855 is fixedly connected to the outside of the external column 853 away from the paddle 854. A friction column 856 is rotatably connected to the inside of the square frame 855. A rubber block 857 is fixedly connected to the outside of the friction column 856. A block surface cutout 858 is opened on the outside of the rubber block 857. Wind power acts on the paddle plate 854, which drives the external column 853 to rotate. This causes the square frame 855 to control the friction column 856 to rub against the surface of the grating plate 83, thereby cleaning impurities through friction, removing stubborn adhering impurities, preventing clogging of the grating holes, breaking up impurity clumps, restoring the screening function, cleaning without dead angles, and covering the entire grating area. The rubber block 857 is made of rubber, which protects the components during the friction process, reduces wear on the grating plate 83, extends its service life, and reduces wear between components. By opening the block surface cuts 858, the deformation performance of the components is enhanced, further improving the working effect of the components.
[0031] In use, the support bracket 1 supports and bears the equipment components. It is connected to the mobile carrier via the buckle 12, facilitating the mobile carrier to move the equipment. The feeding component 5 stores corn seeds, facilitating subsequent seed feeding and enabling continuous operation, thus improving the equipment's efficiency. The feeding component 5 also stirs the internal corn seeds to reduce material adhesion or sticking, preventing impact on planting quality and minimizing resource waste. The bottom of the feeding component 5 is connected to the seed metering device 6, which is an air-suction type, facilitating quantitative seed dispensing and ensuring the quality of equipment operation. Seeds move from the seed metering device 6 to the conveying pipe 7, achieving the sowing effect. When the mobile carrier moves the equipment, the irregularly shaped blocks at the bottom of the irregularly shaped shell 9 till the soil, allowing seeds to enter the soil through the conveying pipe 7. The bulldozer 11, with its wide outer and narrow inner structure, rotates with the soil... Friction causes the soil to accumulate, thus covering the seeds. The covered soil is then rolled by the foot assembly 3 to increase the contact density between the seeds and the soil, reduce soil porosity, reduce water loss to the air, and reduce soil moisture evaporation. This prevents seeds from being displaced by water flow or soil movement during rainfall, irrigation, or field operations after sowing, stabilizing the sowing depth. Rolling also makes the soil thickness in the seed furrow more uniform, preventing fluctuations in actual sowing depth due to loose soil and ensuring consistent emergence time for corn seedlings. The stabilizing component 4 acts as a shock absorber, reducing vibrations generated by the mixing of the feeding component 5 and the amplitude of vibrations during equipment movement, thus improving the stability of equipment operation. The hydraulic rod 10 controls the lifting of the irregularly shaped shell 9, allowing the stabilizing component 4 to slide on the support rod 2, thereby adjusting the position of the equipment and thus adjusting the sowing spacing.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
