Description

Technical Field

[0001] The utility model relates to the technical field of agricultural sowing, in particular to a crop furrow sowing shallow buried drip irrigation seeder. Background Art

[0002] In traditional agricultural seeding and irrigation technology, planters usually rely on simple mechanical devices such as sprocket-driven seed discharge systems that form grooves in the soil and release seeds at the same time. Common irrigation methods include surface irrigation and sprinkler irrigation systems, which provide water by covering a large area rather than specifically targeting the root zone of the crop for water supply.

[0003] These traditional systems have multiple technical problems. First, because the sowing machinery cannot accurately control the depth and spacing between the seeds and the irrigation sprinkler pipes, the seeds are often unevenly watered, affecting the growth quality and yield of the crops. Second, traditional irrigation methods result in a large waste of water resources, because most of the water evaporates or is lost before reaching the roots of the crops, especially in arid areas, and this irrigation efficiency is extremely low. In addition, due to the limitations of sowing and irrigation technology, the growth environment of crops is often not optimized, especially in terms of soil quality and water retention capacity, which further limits the healthy development of crops and yield increases.

[0004] Therefore, a crop furrow sowing shallow buried drip irrigation seeder is proposed to solve the above-mentioned problems. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0039] See also Figure 1-4 , a crop furrow sowing shallow buried drip irrigation seeder according to some embodiments of the utility model is described below.

[0040] The embodiment of the first aspect of the utility model provides a crop furrow sowing shallow buried drip irrigation seeder. In some embodiments of the utility model, such as Figure 1-4 As shown, the crop furrow sowing shallow buried drip irrigation seeder includes:

[0041] The seed bin 1 is installed on the assembly frame 2 along an extension direction, and the assembly frame 2 is used to be assembled and fixed with the agricultural vehicle so that the agricultural vehicle can drive the seed bin 1 to move along the travel direction; the seed bin 1 has a conical cavity 101 inside for storing crop seeds.

[0042] The self-propelled frame 3 is fixed on the assembly frame 2; the self-propelled frame 3 is connected to the seed bin 1 to support the seed bin 1 on the ground where the agricultural vehicle is traveling; the self-propelled frame 3 includes a conical plow 301, and a seed placement cavity 3011 is formed on the conical plow 301; when the conical plow 301 forms a sowing furrow on the ground along the traveling direction, the seed placement cavity 3011 connects the conical cavity 101 and the sowing furrow.

[0043] The winding reel 4 is rotatably mounted on the assembly frame 2; the drip irrigation pipe is wound on the winding reel 4, and the self-propelled frame 3 also includes a pressure wheel 302 for laying the drip irrigation pipe at the bottom of the sowing furrow; the pressure wheel 302 is located behind the conical plow 301 along the travel direction.

[0044] The utility model provides a crop furrow sowing shallow buried drip irrigation seeder, in which the seed bin 1 is a key component, which is used to store crop seeds. A conical cavity 101 is designed inside the seed bin 1, which helps the seeds to move downward evenly by gravity, ensuring a continuous and uniform supply of seeds. The design of the conical cavity 101 avoids the clogging and aggregation of seeds in the bin, thereby improving the accuracy and efficiency of sowing; the assembly frame 2 is a structure for mounting the seed bin 1 on an agricultural vehicle. It enables the seed bin 1 to be installed along an extension direction, ensures the stability of the seed bin 1, and allows the agricultural vehicle to drive the seed bin 1 to move in the direction of travel. This installation method simplifies the mechanical structure and enhances the overall durability and reliability.

[0045] When the agricultural vehicle starts to move, the seed bin 1 mounted on the assembly frame 2 also moves with it, and the seeds are released from the conical cavity 101 through the opening at its bottom. A precisely controlled seed discharge mechanism (such as a roller or a vibration plate) ensures that the seeds are placed into the soil at a constant rate and spacing, and the seeds are precisely placed in the pre-dug grooves through the sowing pipes; while sowing, drip irrigation pipes will also be arranged in the soil next to the seeds. These pipes are usually laid through another set of mechanical devices (which may be another parallel assembly frame 2). The equipment can work synchronously with the movement of the seed bin 1. After the pipes are installed, irrigation can be started immediately to ensure that the soil around the seeds maintains appropriate humidity, thereby promoting rapid germination and growth of the seeds; the drip irrigation system is designed to provide moisture instantly during the planting process, which helps to optimize the use of water resources, especially in arid or water-limited areas. It can be adjusted through a controller to flexibly adjust the amount of water according to climatic conditions, soil type and crop needs.

[0046] By integrating the sowing and irrigation processes, the operating efficiency and crop growth conditions are significantly improved. Precision irrigation that locks in the roots of crops reduces water evaporation losses and improves water utilization efficiency. It is driven by agricultural vehicles and is easy to operate, greatly reducing manpower requirements and operational complexity.

[0047] The self-propelled frame 3 is a key component installed on the assembly frame 2. It directly supports the seed bin 1 and ensures that the seed bin 1 moves smoothly along the travel direction of the agricultural vehicle. The design of the self-propelled frame 3 allows the machine to move autonomously on different terrains, increasing the adaptability and flexibility of the machine; the self-propelled frame 3 is equipped with a conical plow 301, which is a tool for forming a sowing furrow on the ground. The conical plow 301 not only cuts the soil to form a groove, but also has a land preparation function, creating ideal conditions for the sowing and growth of seeds; the conical plow 301 is designed with a seed drop chamber 3011, which is a transmission channel for seeds from the seed bin 1 to the sowing furrow. The design of the seed drop chamber 3011 ensures that the seeds can be accurately transported from the conical cavity 101 of the seed bin 1 to the sowing furrow.

[0048] When the agricultural vehicle starts and pushes the seeder forward, the conical plow 301 on the self-propelled frame 3 cuts into the soil and forms a sowing furrow along the direction of travel. The design of the conical plow 301 enables it to slightly turn the soil while cutting, which helps to increase the looseness and air permeability of the soil and create a better environment for seed growth; the seeds move downward in the conical cavity 101 of the seed bin 1 by gravity, and are accurately placed in the sowing furrow formed by the conical plow 301 through the seed drop cavity 3011. The design of the seed drop cavity 3011 ensures that the seeds will not be blocked or scattered during transportation, and can be evenly sown at a preset depth and spacing; while the seeds are being sown, the drip irrigation pipes are arranged in the soil next to the seeds or directly covering the seeds above the seeds through another set of mechanical devices, which ensures that water is directly transported to the soil near the seeds, improves water utilization efficiency and promotes rapid seed germination.

[0049] By integrating the conical plow 301 and the seed drop chamber 3011, the seeder not only improves the speed of sowing, but also ensures the accuracy of sowing and the optimal growth conditions of seeds. The use of the self-propelled frame 3 reduces the dependence on agricultural vehicles, making the machine operation easier and more automated. The simultaneous installation of the drip irrigation system ensures the effective use of water resources, which is particularly suitable for arid areas or farmland with limited water resources.

[0050] The reel 4 is rotatably mounted on the assembly frame 2 and is used to store the drip irrigation pipe. The reel 4 can automatically release the drip irrigation pipe when the agricultural vehicle is moving, ensuring the smooth deployment and correct laying of the drip irrigation pipe; the pressing wheel 302 is installed on the self-propelled frame 3 and is located behind the conical plow 301. Its main function is to press the drip irrigation pipe into the bottom of the sowing furrow to ensure that the drip irrigation pipe is in close contact with the soil, thereby improving the irrigation efficiency and the direct use of water.

[0051] When the seeder starts to operate, as the agricultural vehicle moves forward, the reel 4 starts to rotate and gradually releases the drip irrigation pipe. The drip irrigation pipe is smoothly unfolded from the reel 4 and passes through a series of guide devices (which may include a guide tube or a guide wheel) to ensure that it is correctly laid in the sowing furrow. After the drip irrigation pipe is placed in the sowing furrow, the pressing wheel 302 then passes through the sowing furrow and rolls along the direction of travel. The function of the pressing wheel 302 is to ensure that the drip irrigation pipe is pressed into the soil and is in close contact with the soil. This not only prevents the displacement of the drip irrigation pipe, but also increases the efficiency of water reaching the roots of plants directly through the drip irrigation pipe. The weight and shape of the pressing wheel 302 are carefully designed to adapt to different soil types and depth requirements, thereby ensuring the best laying effect of the drip irrigation pipe.

[0052] Through the automated winding reel 4 and pressure wheel 302 system, the laying process of the drip irrigation pipe does not require human intervention, which greatly improves the efficiency and accuracy of the operation. Since the drip irrigation pipe is in close contact with the soil, water is directly delivered to the roots of the crops, reducing water evaporation and waste. It is particularly suitable for use in arid areas. Accurate water management helps to improve crop growth conditions, thereby potentially increasing crop yield and quality.

[0053] In summary, by integrating the sowing and drip irrigation systems, the machine can complete the sowing and laying of drip irrigation pipes in the same operation process, which not only improves the operation efficiency, but also reduces the complexity and manpower requirements in the operation process; the conical cavity 101 design inside the seed bin 1 helps to achieve uniform and continuous seed supply, and the seed drop cavity 3011 on the conical plow 301 ensures that the seeds fall accurately in the predetermined sowing furrow. At the same time, the drip irrigation pipe is precisely laid at the bottom of the sowing furrow to ensure that water resources are directly delivered to the surrounding of the seeds. Such a design greatly improves the utilization efficiency of water resources and promotes the healthy growth of crops. By precisely controlling sowing and irrigation, the machine reduces the waste of seeds and water resources. Especially in areas with tight water resources, the drip irrigation system can effectively deliver water directly to the roots of crops, thereby saving water and improving the production efficiency of crops.

[0054] Specifically, the extending direction is the x-axis direction of the plane, and the moving direction is the y-axis direction of the plane.

[0055] In any of the above embodiments, at least one seed bin 1 is arranged along the extension direction, and the extension direction is perpendicular to the traveling direction.

[0056] In this embodiment, the basic function of the seed bin 1 is to store a large amount of seeds and continuously supply these seeds during the sowing process. The design of the seed bin 1 needs to ensure that the seeds can be safely stored without being affected by moisture or other environmental factors; in order to ensure that the seeds are evenly distributed in the soil, the seed bin 1 needs to release the seeds evenly to the designated location through a series of mechanical components (such as a seed wheel or a vibration mechanism).

[0057] The seed bin 1 is arranged along the width direction of the machine (i.e. perpendicular to the direction of travel). This layout allows the machine to cover a wider area in one pass, thereby improving work efficiency. This arrangement allows seeds to be sown at multiple points at the same time, which is suitable for large-scale crop planting, especially in commercial agricultural operations that require rapid coverage of large areas of land. When the seeder starts to move, each seed bin 1 begins to release seeds downward through its internal seeding mechanism. The seeds are evenly discharged through small holes or slots at the bottom of the bin to ensure that each sowing point can receive the right amount of seeds. The position of seed release is precisely controlled to maintain a consistent depth with the soil surface to promote optimal germination and growth of the seeds. While the seeds are being released, other components of the seeder, such as the drip irrigation pipe laying device and the soil treatment tool (such as the conical plow 301), are also working at the corresponding positions. This synchronization ensures that the soil is properly treated while the seeds are being broadcast, and the drip irrigation pipes are properly installed to provide the necessary water resources for the seeds.

[0058] In any of the above embodiments, the crop furrow seeding shallow buried drip irrigation seeder also includes:

[0059] A rotating shaft 5 is rotatably mounted on the assembly frame 2, and the rotating shaft 5 passes through all the seed bins 1 along the extension direction; a seed dropping wheel 6 is fixedly mounted on the portion of the rotating shaft 5 located inside the seed bin 1, and the seed dropping wheel 6 blocks the bottom of the seed bin 1;

[0060] The driving mechanism 7 is assembled on the assembly frame 2 ; the driving mechanism 7 is connected to the rotating shaft 5 to drive the rotating shaft 5 to rotate.

[0061] In this embodiment, the rotating shaft 5 is a long shaft mounted on the assembly frame 2, and passes through all seed bins 1 along the extension direction of the machine. The main function of the rotating shaft 5 is to support and drive the seed dropping wheel 6 in each seed bin 1 to ensure that the seeds are released from the seed bin 1 evenly and continuously; the seed dropping wheel 6 is fixedly mounted on the part of the rotating shaft 5 located in the seed bin 1, close to the bottom of the seed bin 1. The seed dropping wheel 6 is designed to block the opening at the bottom of the seed bin 1, and control the release of seeds through the small holes or grooves 601 thereon when the rotating shaft 5 rotates. This design enables the seed dropping wheel 6 to act as a blocker to prevent seeds from falling freely, and as a regulator to accurately control the release speed and quantity of seeds; the driving mechanism 7 is responsible for providing power to rotate the rotating shaft 5 together with the seed dropping wheel 6 thereon. This is usually achieved by an electric or hydraulic motor, and the rotation of the motor is transmitted to the rotating shaft 5 through a mechanical connecting rod or a direct connection.

[0062] When the seeder starts working, the drive mechanism 7 starts, driving the shaft 5 together with the seed drop wheel 6 above to rotate. The seed drop wheel 6 is designed to release seeds intermittently through specific holes or grooves 601 when it rotates. These openings are precisely aligned with the outlet at the bottom of the seed bin 1, and release seeds into the sowing furrow below as needed; the continuous movement of the shaft 5 ensures the stability of the seed drop wheel 6 and the uniform seed release, which is crucial to maintaining the uniform distribution of seeds in the sowing furrow. The performance of the drive mechanism 7 directly affects the rotation speed of the shaft 5 and the seed drop wheel 6, and then affects the frequency and quantity of seed release. The sowing density can be accurately controlled by adjusting the setting of the drive mechanism 7; while sowing, other systems (such as soil treatment and drip irrigation pipe laying) are also in progress. All these operations need to be closely synchronized with the movement of the shaft 5 and the seed drop wheel 6. This synchronization ensures that the seeds fall into the pre-treated soil and then drip irrigation is carried out to maximize the growth potential of the seeds and the utilization efficiency of water resources.

[0063] In any of the above embodiments, the seed drop wheel 6 is provided with a plurality of grooves 601 along the circumference, and the grooves 601 are used to accommodate crop seeds. The rotation of the seed drop wheel drives the grooves to move circumferentially, accommodating the seeds in the conical cavity, and after a half-circle rotation, the seeds fall out of the corresponding port of the hose by gravity, and enter the sowing furrow through the hose and the seed drop cavity.

[0064] In this embodiment, the seed drop wheel 6 is designed with multiple grooves 601 along the circumference, and the size and shape of these grooves 601 are specifically used to accommodate crop seeds. Such a design ensures that the seeds can be accurately captured and released at the appropriate position; the design of the grooves 601 is not only used to accommodate seeds, but also to control the release rate and quantity of seeds during sowing through the position and depth of the grooves 601. This precise control is achieved by aligning the grooves 601 with the bottom of the seed bin 1 during the rotation of the seed drop wheel 6.

[0065] Before the sowing process begins, the seeds are loaded into the seed bin 1, and the seed drop wheel 6 then starts to rotate. As the seed drop wheel 6 rotates, each groove 601 is dynamically filled with seeds accumulated in the seed bin 1 as it passes through the loading area at the bottom of the seed bin 1. When the groove 601 containing the seeds rotates to the corresponding exit position at the bottom of the seed bin 1, the groove 601 releases the seeds accurately into the sowing furrow below due to gravity and design positioning. The rotation speed of the seed drop wheel 6 and the design of the groove 601 (such as shape, size and spacing) determine the uniformity of seed release and sowing density. By adjusting the settings of the drive mechanism 7 (such as the rotation speed), the rotation speed of the seed drop wheel 6 can be changed, thereby adjusting the frequency of seed release. The size and number of the grooves 601 can also be customized according to the size of different seeds and sowing requirements to meet different crop planting needs. While the seed drop wheel 6 releases the seeds, the seeder may also be equipped with other simultaneous operating functions, such as soil tillage and drip irrigation pipe laying, to ensure that the seeds receive the necessary soil treatment and water supply immediately after landing.

[0066] In any of the above embodiments, a driving wheel 8 is fixedly mounted on the rotating shaft 5, and an elastic sheet 9 matched with the driving wheel 8 is fixed on the assembly frame 2, and the elastic sheet 9 and the driving wheel 8 clamp the drip irrigation pipe.

[0067] The driving wheel 8 is used to drive the drip irrigation pipe between the winding disc 4 and the pressing wheel 302 to move.

[0068] In this embodiment, the driving wheel 8 is fixedly mounted on the rotating shaft 5, and is mainly used to drive the movement of the drip irrigation pipe. The driving wheel 8 directly contacts the drip irrigation pipe through the friction force on its surface, and transmits power to the drip irrigation pipe, so that it moves from the winding disk 4 to the pressing wheel 302; the elastic sheet 9 is fixed on the assembly frame 2, opposite to the driving wheel 8. The main function of the elastic sheet 9 is to clamp the drip irrigation pipe by cooperating with the driving wheel 8, increase the friction between the driving wheel 8 and the drip irrigation pipe, and ensure the stable movement of the drip irrigation pipe.

[0069] When the seeder is started, the driving mechanism 7 causes the driving wheel 8 on the rotating shaft 5 to start rotating. The driving wheel 8 contacts the drip irrigation pipe through the friction material on its surface, driving the drip irrigation pipe to move from the reel 4 to the pressing wheel 302. This movement is continuous, ensuring that the drip irrigation pipe can be continuously laid in the soil during the movement of the seeder; the role of the elastic sheet 9 is to provide the necessary pressure and clamp the drip irrigation pipe together with the driving wheel 8. This clamping method is achieved through the elastic force of the elastic sheet 9, ensuring that the drip irrigation pipe can be evenly and stably transmitted even in the case of uneven ground or machine vibration. The material and design of the elastic sheet 9 enable it to adapt to drip irrigation pipes of different thicknesses and maintain constant pressure without damaging the drip irrigation pipe; while the drip irrigation pipe is driven by the driving wheel 8, the pressing wheel 302 follows behind and presses the drip irrigation pipe into the soil that has just been sown. This synchronous operation ensures that the drip irrigation pipe is placed immediately after the seeds are sown, optimizes the use of water resources, and promotes the rapid germination and growth of seeds.

[0070] In any of the above embodiments, the driving mechanism 7 includes:

[0071] The input shaft 701 is rotatably mounted on the assembly frame 2 ; the input shaft 701 and the rotating shaft 5 transmit torque via the transmission chain 702 .

[0072] The transmission gear 703 is mounted on the input shaft 701 and the rotating shaft 5 respectively; the transmission chain 702 is sleeved on the transmission gear 703 .

[0073] In this embodiment, the input shaft 701 is rotatably mounted on the assembly frame 2 and is the primary power input point of the drive mechanism 7. The input shaft 701 is usually driven by an external power source (such as an electric motor or an internal combustion engine) and is responsible for receiving and transmitting power to the rotating shaft 5. The transmission gears 703 are respectively mounted on the input shaft 701 and the rotating shaft 5. The main function of these gears is to enhance the efficiency and accuracy of torque transmission and ensure the stable transmission of power through the meshing of the gears. The transmission chain 702 is sleeved on the transmission gear 703 and acts as an intermediary connecting the input shaft 701 and the rotating shaft 5. The transmission chain 702 transmits torque from the input shaft 701 to the rotating shaft 5 through the meshing action between the gears.

[0074] When the seed drill is started, the power source drives the input shaft 701 to rotate. The transmission gear 703 on the input shaft 701 rotates with the input shaft 701, and engages with the chain in the transmission chain 702 through the teeth on it, and starts to transmit power. The transmission chain 702 transmits this power to the transmission gear 703 on the rotating shaft 5. Because the transmission chain 702 and the gears are precisely designed, this transmission is very effective and there is almost no power loss; by changing the size ratio of the transmission gear 703, the torque and speed ratio can be adjusted. For example, if the gear on the input shaft 701 is smaller and the gear on the rotating shaft 5 is larger, the torque can be increased and the speed can be reduced to adapt to the situation where a larger force is required but the speed is low. This adjustment function allows the seed drill to be optimized according to different operating requirements (such as soil type, seed type and operating speed); the design of the transmission chain 702 and the gear system ensures the stability and reliability of the entire drive mechanism 7. The transmission chain 702 system has higher wear resistance and load-bearing capacity than belt drive, and is suitable for use in harsh farmland environments; the efficient operation of the drive mechanism 7 ensures the synchronous operation efficiency of the entire seeder, including the coordinated movement of the seed drop wheel 6 of the seed bin 1, the drive wheel 8 on the rotating shaft 5, and possible other supporting mechanical parts.

[0075] In any of the above embodiments, rollers 10 are rotatably mounted on both ends of the assembly frame 2, and the central axis of one roller 10 is connected to the input shaft 701; when the assembly frame 2 moves along the travel direction, the rollers 10 cooperate with the ground to drive the input shaft 701 to rotate.

[0076] In this embodiment, the rollers 10 are mounted at both ends of the assembly frame 2 and directly contact the ground. The rollers 10 not only support the weight of the assembly frame 2 and the entire machine, but are also responsible for rotating when the machine moves forward; in particular, the center axis of one of the rollers 10 is connected to the input shaft 701, so that the roller 10 can directly drive the input shaft 701 when rotating; the input shaft 701, as part of the driving mechanism 7, is usually driven by an external power source. In this design, the input shaft 701 also obtains power through the center axis connected to the roller 10, realizing the function of self-driving.

[0077] When the seeder starts to move in the field, the roller 10 in contact with the ground rotates due to the movement of the machine. Since the central axis of one of the rollers 10 is directly connected to the input shaft 701, the rotation of the roller 10 directly drives the input shaft 701 to rotate. This transmission method fully utilizes the kinetic energy of the machine's movement and converts it into the rotational power of the input shaft 701 without the need for an additional power source; the power generated by the rotation of the roller 10 drives the input shaft 701. This design greatly enhances the energy efficiency of the seeder and reduces the dependence on fuel or electricity. This self-driving mechanism is particularly suitable for farmland with a wide operating area and long-term operation of the machine, which can effectively reduce energy consumption and operating costs; the contact between the roller 10 and the ground ensures stable power input, so that the rotation of the input shaft 701 is smooth and continuous. This is crucial to ensure the synchronous operation of the entire sowing and irrigation system. The rotation of the input shaft 701 not only drives the transmission chain 702 and the gear system connected to it, and then drives the seed drop wheel 6 and other mechanical components in the seed bin 1, but also ensures the accuracy and coordination of the entire sowing and irrigation operation.

[0078] In any of the above embodiments, the self-propelled frame 3 further includes:

[0079] The frame 303 is assembled on the assembly frame 2 and corresponds to the seed bin 1 one by one; the conical plow 301 and the pressure wheel 302 are respectively assembled on the frame 303.

[0080] The hose 304 is installed on the frame 303 ; the hose 304 is used to connect the conical cavity 101 and the seed dropping cavity 3011 .

[0081] In this embodiment, the frame 303 is the main structure of the self-propelled frame 3, which is installed on the assembly frame 2 and corresponds to the seed bin 1 one by one. The frame 303 provides a stable platform for assembling other key components, such as the conical plow 301, the pressure wheel 302 and the hose 304. The conical plow 301 is assembled on the frame 303 to form a sowing furrow in the soil. The design of the conical plow 301 enables it to cut the soil during movement and create a groove suitable for seed placement. The pressure wheel 302 is also assembled on the frame 303 and is located behind the conical plow 301. The main function of the pressure wheel 302 is to compact the soil after the seeds are sown to ensure good contact between the seeds and the soil, thereby promoting the stability and growth of the seeds. The hose 304 is installed on the frame 303 to connect the conical cavity 101 in the seed bin 1 and the seed drop cavity 3011 on the conical plow 301. The main function of the hose 304 is to ensure that the seeds can be smoothly transferred from the seed bin 1 to the sowing furrow.

[0082] When the seeder starts working and moves forward, the conical plow 301 on the frame 303 first cuts into the soil to form a suitable sowing furrow. In this process, the design of the conical plow 301 needs to take into account the type and moisture of the soil to adjust the cutting depth and force; the seeds enter the connected hose 304 through the conical cavity 101 in the seed bin 1. As the seeder moves, the seeds flow smoothly to the seed drop cavity 3011 through the hose 304. The flexibility and wear resistance of the hose 304 ensure that the seeds will not be damaged during the transportation process. The seed drop cavity 3011 is located at the end of the conical plow 301, where the seeds are accurately released into the pre-formed sowing furrow; once the seeds are released in the sowing furrow, the subsequent pressing wheel 302 follows the conical plow 301 to compact the soil on the sowing furrow. This step is crucial to ensure good contact between the seeds and the soil and maintain moisture, which helps the germination and initial growth of the seeds; the coordinated operation of all components on the self-propelled frame 3 ensures the consistency and efficiency of the sowing process. From soil preparation with the Conical Plough 301 to seed delivery and soil compaction, each step is closely linked to optimize the entire sowing process.

[0083] In any of the above embodiments, a pressing plate 11 is mounted on the frame 303 via a chain; the pressing plate 11 is located behind the pressing wheel 302 along the traveling direction so as to backfill the soil excavated by the conical plow 301 into the sowing furrow.

[0084] In this embodiment, the pressing plate 11 is mounted on the frame 303 of the self-propelled frame 3 through a chain and is located behind the pressing wheel 302 along the traveling direction. The main function of the pressing plate 11 is to backfill the soil excavated and turned up by the conical plow 301 into the sowing furrow to ensure that the sowing furrow is evenly covered, thereby protecting the seeds from direct influence of the external environment, such as wind, rain and direct sunlight.

[0085] When the seeder starts to move and work, the conical plow 301 first forms a sowing furrow in the soil and places seeds. As the machine moves forward, the conical plow 301 pushes part of the soil to both sides of the furrow. The pressing plate 11 is located behind the conical plow 301 and the pressing wheel 302. As the self-propelled frame 3 moves, the pressing plate 11 is connected by a chain to maintain a certain height and angle. When the pressing plate 11 passes over the sowing furrow, it pushes the soil turned up by the conical plow 301 back into the sowing furrow; after the soil is backfilled into the sowing furrow by the pressing plate 11, the pressing wheel 302 following closely compacts the backfilled soil. This step is very important because it ensures good contact between the soil and the seeds, promotes water absorption and germination of the seeds, and the compacted soil can also prevent water from evaporating too quickly and protect the seeds from being blown away by the wind or eaten by animals such as birds; the coordinated operation of the pressing plate 11 and the pressing wheel 302 ensures the integrity and efficiency of the sowing process. This synchronous operation mode not only improves the working efficiency of the seeder, but also optimizes the growth environment of the seeds. The pressure plate 11 is installed through a chain to ensure that its height and angle can be adjusted according to different soil conditions and operation requirements to achieve the best backfilling effect.

[0086] In any of the above embodiments, a blocking wheel 12 is rotatably mounted on the frame 303; the blocking wheel 12 is located in front of the conical plow 301 along the traveling direction.

[0087] In this embodiment, the blocking wheel 12 is rotatably mounted on the frame 303 and is located in front of the conical plow 301. The main function of the blocking wheel 12 is to adjust the amount and texture of soil entering the conical plow 301, and to help level and pre-treat the soil so as to create optimal conditions for the digging and seed broadcasting of the conical plow 301.

[0088] When the planter moves in the direction of travel, the blocking wheel 12 first contacts the soil on the ground. Since the blocking wheel 12 is located in front of the conical plow 301, it can effectively adjust the distribution and flatness of the soil. The blocking wheel 12 can flatten large pieces of soil and other obstacles through its rotation, reducing the resistance and potential damage when the conical plow 301 enters the soil. This process ensures that the conical plow 301 can dig more smoothly and effectively; through the pretreatment of the retaining wheel 12, the sowing furrows dug by the conical plow 301 are more regular and uniform, which is crucial to the uniform distribution of seeds and subsequent growth. The adjustment function of the retaining wheel 12 also includes possible depth control, which can help set the depth of the sowing furrow to ensure that the seeds are at the optimal soil depth, thereby optimizing the growth environment of the seeds; the role of the retaining wheel 12 is not limited to the pretreatment of the soil, it also coordinates the conical plow 301 and other components such as the pressure wheel 302 during the entire sowing process to ensure that all components work together to achieve the highest efficiency. During the entire sowing process, the synchronous operation of the retaining wheel 12 and the conical plow 301, pressure wheel 302 and other components ensures that each step from soil treatment to seed broadcasting to soil backfilling is consistent and efficient.
