[0060] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0061] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0062] Reference Figures 1 to 8 , is an embodiment of the present invention, which proposes a corn and soybean strip composite planting seeder, including a frame and a furrowing and fertilizing device 2, a sowing device 5 and a soil covering device 6 arranged on the frame in sequence, and the sowing device 5 has several sowing devices 5, and the several sowing devices 5 are arranged on the frame at intervals; it also includes: a covering device 7, which is arranged at the bottom of the frame, and the covering device 7 is located between the furrowing and fertilizing device 2 and the sowing device 5; the covering device 7 includes: a support plate 701, which is arranged on the frame 1, and the support plate 701 has a connecting end; a film spreading roller 703, which is rotatably arranged on the connecting end; a film pressing wheel 703, which has several, and the several film pressing wheels 704 are symmetrically arranged at both ends of the support plate 701, and the film pressing wheels 704 are used to press the two sides of the film into the soil; a pressing component 604, which is arranged on the frame, and the pressing component 604 is arranged at the end of the frame 1, and the pressing component 604 is used to compact the two sides of the film and the soil covering the film.

[0063] In the above scheme, the operation begins with the furrowing and fertilizing device 2 located at the front of the frame 1. It creates a fertilizer furrow of appropriate depth and width in the soil. The fertilizer applicator then accurately applies fertilizer into the furrow, providing sufficient nutrients for the subsequent growth of corn and soybeans. Subsequently, the film covering device 7 begins operation. The film spreading roller 703 on the support plate 701 rotates slowly, smoothly unrolling the film roll. As the planter advances through the field, the film gradually covers the soil. Simultaneously, the film pressing wheels symmetrically positioned at each end of the support plate firmly press the film's edges into the soil. This not only provides excellent insulation, maintaining a stable soil temperature and facilitating seed germination and growth, but also effectively retains moisture, reducing evaporation and providing a suitable moisture environment for crop growth. It also inhibits weed growth and reduces competition for crop nutrients. Next, several seeding devices are spaced apart on the frame 1 according to the strip planting requirements for corn and soybeans. The seed meter dispenses a fixed amount of corn or soybean seeds from the seed box and then accurately sows them into the soil through the seeding tube. This allows for precise control of seed sowing rates, row spacing, and plant spacing, ensuring a rational spatial mix of corn and soybeans, giving full play to interspecific mutualism and efficiently utilizing resources such as light, heat, water, and fertilizer. After sowing, the covering device quickly follows. The covering plate cleverly guides the soil over the sown seeds, covering them. The covering wheel then further compacts the soil, bringing the seeds into close contact with the soil, creating favorable conditions for seed germination and growth. Finally, the pressing assembly at the end of frame 1 compacts both sides of the film and the soil covering it. Pressing wheel 6041 is connected to the frame via a pressing spring, which automatically adjusts pressure according to the hardness of the soil. This operation ensures that the film is firmly covered on the ground, preventing it from being blown away by the wind, while also making the soil more compact, which is beneficial for moisture conservation and seed growth.

[0064] Beneficial Effects: First, it can complete multiple operations simultaneously, including seedling strip preparation, fertilization, corn and soybean strip sowing, soil covering, and compaction. This significantly reduces the number of operations and time required, significantly improving planting efficiency. Second, the design of the seeding device allows precise adjustment of row and plant spacing according to strip planting requirements, achieving a rational spatial balance between corn and soybeans, fully utilizing resources such as light, heat, water, and fertilizer, and ultimately improving yield and quality. Third, the synergistic effect of the soil covering and compaction components ensures close contact between seeds and soil, ensuring optimal soil compaction and ensuring strong support for seed germination and growth. Furthermore, the film covering device creates an optimal environment for crop growth, ensuring high-quality planting. Fourth, the planter's rational design and easy operation significantly reduce labor intensity. Farmers can simply drive the planter across the field to complete a series of planting operations, eliminating the need for tedious manual operations. Fifth, its high adaptability allows it to adapt to varying soil conditions and planting requirements, enabling smooth corn and soybean strip planting in both plains and mountainous areas.

[0065] Furthermore, the covering device includes: a first covering plate 601, which has several first covering plates 601 and is rotatably set at the bottom of the frame 1 and is located outside the film pressing wheel 704, and the first covering plate 603 is used to push soil toward the film pressing wheel; an upper soil cylinder 603, which is rotatably set on the frame 1, and the upper soil cylinder 603 is located at the tail end of the frame. The upper soil cylinder 603 is hollow inside, and soil outlets are spaced apart on the outer wall of the upper soil cylinder 603. The upper soil cylinder 603 is used to cover the surface of the film with soil; a second covering plate 602, which has several second covering plates 602, which are symmetrically set on both sides of the upper soil cylinder 603, and the second covering plate 602 is used to push soil into the upper soil cylinder 603.

[0066] In the above scheme, the soil covering device 6 plays a vital role in the strip composite planting seeder. It can ensure that the seeds are covered with soil and provide a good environment for the germination and growth of the seeds. The soil covering device 6 mainly consists of a first soil covering plate 601, an upper soil cylinder 603, a second soil covering plate 602 and a suppression assembly 604. First, a plurality of first soil covering plates 601 are rotatably arranged at the bottom of the frame 1 and are located outside the film pressing wheel 704. The function of the first soil covering plates 601 is to push soil toward the film pressing wheel 704, covering the soil on both sides of the film, further fixing the film, and also providing a certain covering layer for the seeds. The number of first soil covering plates 601 can be adjusted according to actual needs to ensure a uniform covering effect. The rotation of the first soil covering plates 601 is driven by the power system of the seeder, and its rotation speed and angle can be optimized according to soil conditions and operating requirements. The upper soil cylinder 603 is rotatably arranged on the frame 1 and is located at the rear end of the frame 1. The upper soil cylinder 603 is hollow inside, and a soil outlet is spaced apart on the outer wall. The effect of upper soil barrel 603 is to cover the surface of film with soil, providing a thicker covering layer for seeds. The rotation of upper soil barrel 603 can make soil be discharged from the unearthing opening evenly, covering the surface of film. The rotating speed of upper soil barrel 603 and the size of unearthing opening can be adjusted according to the fluidity and covering requirements of soil to ensure good covering effect. Several second covering discs 602 are symmetrically arranged on both sides of upper soil barrel 603. The effect of second covering discs 602 is to push soil into upper soil barrel 603, providing continuous soil supply for upper soil barrel 603. The number and position of second covering discs 602 can be adjusted according to the size of upper soil barrel 603 and soil conditions to ensure that upper soil barrel 603 can work normally. The rotation of second covering disc 602 is also driven by the power system of seed drill, and its rotating speed and angle can match the working requirements of upper soil barrel 603.

[0067] In summary, the various components of the soil covering device 6 cooperate with each other to accomplish the tasks of soil covering and compaction. The coordinated operation of the first soil covering plate 601, the upper soil cylinder 603, the second soil covering plate 602, and the suppression assembly 604 enables the soil covering device 6 to achieve efficient and uniform soil covering, providing a favorable soil environment for crop growth. The soil covering device 6 not only improves the efficiency and quality of agricultural production but also adapts to varying soil conditions and planting requirements, bringing greater convenience and benefits to farmers.

[0068] Furthermore, the suppression assembly includes: a plurality of swing rods, which are hinged at intervals on the frame; a plurality of suppression wheels, each of which is rotatably set on the other end of a swing rod; a fixed rod, which is set on the frame; a spring rod, one end of which is slidably set on the fixed rod and the other point is hinged to the swing rod, and the spring rod is used to provide force for the suppression wheel to stick to the ground.

[0069] In the above scheme, the pressing assembly 604 plays an important role in the strip composite planting seeder. It can compact the soil and provide a good soil environment for seed growth. The pressing assembly 604 mainly consists of a swing rod 6044, a pressing wheel 6041, a fixed rod 6043 and a spring rod 6042.

[0070] First, several swing arms 6044 are hingedly mounted on the frame at intervals. The number of swing arms 6044 can be adjusted according to actual needs to ensure comprehensive soil compaction. The hinged design of the swing arms 6044 allows them to swing freely within a certain range, adapting to varying terrain and soil conditions. When the planter travels over uneven ground, the swing arms 6044 automatically adjust their angles based on the surface's undulations, ensuring that the pressing wheels 6041 maintain good contact with the ground. There are multiple pressing wheels 6041, each pivoted on the other end of a swing arm 6044. The pressing wheels 6041 are the core component of the pressing assembly 604. They come into direct contact with the soil, compacting it through their own weight and rotation. The number and size of the pressing wheels 6041 can be selected based on the planter's operating width and soil compaction requirements. The rotating design of the pressing wheels 6041 reduces friction with the soil, improving compaction efficiency while also preventing excessive soil damage. The fixed rod 6043 is set on the frame to provide fixed support for the spring rod 6042. One end of the spring rod 6042 is slidably set on the fixed rod 6043, and the other end is hinged to the swing rod 6044. The function of the spring rod 6042 is to provide force for the pressing wheel 6041 to stick to the ground. When the planter is driving, the spring rod 6042 will automatically adjust its length according to the ups and downs of the ground, so that the pressing wheel 6041 always maintains a certain pressure in contact with the ground. The elastic design of the spring rod 6042 can adapt to different soil hardness and terrain changes, ensuring the stability and consistency of the pressing effect. When encountering harder soil, the spring rod 6042 will be compressed, increasing the pressure of the pressing wheel 6041 to achieve a better compaction effect; when encountering softer soil, the spring rod 6042 will extend, reducing the pressure of the pressing wheel 6041 to avoid excessive compaction of the soil.

[0071] Furthermore, the trenching and fertilizing device includes: a plurality of trench openers 21, each of which is arranged at the front of the frame 1; a fertilizer box 3, which is arranged on the frame 1, and the fertilizer box 3 has a plurality of discharge ports 301; a plurality of fertilizer applicators 8, each of which has a feed port and a discharge port, each feed port is connected to a discharge port 301, and the fertilizer applicator 8 has a plurality of fertilizer troughs 8061 inside. After the fertilizer applicator 8 is started, the plurality of fertilizer troughs 8061 are connected to the feed port in sequence, and each discharge port 804 corresponds to a trench opener 21; a feeding member 9, which is slidably arranged in the fertilizer applicator, and the feeding member 9 has a plurality of feeding ends 9011, each feeding end 9011 extends into a fertilizer trough 9061, and the feeding member 9 is used to break up the agglomerated fertilizer.

[0072] In the above scheme, the multiple furrow openers 21 in the ditch fertilization device are evenly distributed in front of the frame 1. The shape and size of the furrow openers 21 can be designed according to actual planting needs to ensure that a trench of appropriate depth and width can be opened in the soil. The fertilizer box 3 is securely mounted on the frame 1 and adopts a large-capacity design to meet the fertilizer needs of large-scale planting. The position and number of the multiple discharge ports 301 at the bottom of the fertilizer box 3 correspond to the feed port 805 of the fertilizer applicator 8, ensuring that fertilizer can be smoothly transported from the fertilizer box 3 to the fertilizer applicator 8.

[0073] There are multiple fertilizer applicators 8, each equipped with a feed port 805 and a discharge port 804. The feed port 805 communicates with the discharge port 301 of the fertilizer bin 3, allowing fertilizer to enter the fertilizer applicator 8 accurately. After the fertilizer applicator 8 is activated, multiple fertilizer troughs 8061 within the fertilizer applicator 8 sequentially connect to the feed port 805, enabling quantitative fertilizer discharge. This allows for precise control of the fertilizer application rate and improves the accuracy and stability of fertilization. Each discharge port 804 corresponds to a furrow opener 21, ensuring that fertilizer is accurately discharged into the furrow created by the furrow opener 21, providing sufficient nutrients for the crops.

[0074] A knockout member 9 is slidably disposed within the fertilizer applicator 8 and has multiple knockout ends 9011. When fertilizer clumps form within the fertilizer applicator 8, the knockout member 9 flexibly slides within the applicator 8, breaking up the clumped fertilizer with the knockout ends 9011. The knockout member 9 can be driven by a motor or hydraulic system, achieving automatic knockout, improving work efficiency and reducing manual intervention.

[0075] The sowing device 5 is mounted on the frame 1 and located behind the furrowing and fertilizing device 2 to ensure uniform seeding depth and spacing. At the same time, the sowing device 5 can be adjusted according to different crop requirements to meet the sowing requirements of corn and soybean strip intercropping modes.

[0076] The soil covering device 6 is mounted on the frame 1, behind the sowing device 5. Its function is to cover the seeds with soil after sowing, providing a favorable growth environment for the seeds and ensuring successful germination and growth. The soil covering device 6 is adjustable and can be adjusted to suit different soil conditions and sowing depths, improving the effectiveness and adaptability of the soil covering.

[0077] When using the strip-shaped composite planting seeder of the present invention, fertilizer is first loaded into the fertilizer box 3, and then seeds are loaded into the sowing device 5. After the seeder is started, the furrow opener 21 creates a furrow in the soil. The fertilizer in the fertilizer box 3 enters the fertilizer applicator 8 through the discharge port 301. The fertilizer applicator 8 then discharges a fixed amount of fertilizer into the furrow created by the furrow opener 21. The sowing device 5 sows the seeds into the furrow, and the covering device 6 covers the seeds with soil. If fertilizer clumps form in the fertilizer applicator 8, the breaking element 9 automatically breaks up the clumps, ensuring smooth fertilization.

[0078] In summary, the strip composite planting seeder of the present invention has significant advantages in the corn and soybean strip interplanting mode. It can not only meet the requirements of fertilization and sowing, improve the efficiency and quality of fertilization and sowing, but also effectively solve the problem of fertilizer caking through the material-beating part 9, ensuring the smooth progress of fertilization operation.

[0079] Furthermore, it also includes: a transmission rod, which is rotatably arranged on the fertilizer box and passes through the fertilizer spreader; the fertilizer spreader includes: a box body, on which the feed port and the discharge port are both opened; a rotating member, which is rotatably arranged in the box body, and the rotating member is arranged on the transmission rod, and the transmission rod is used to drive the rotating member to rotate; a plurality of fertilizer troughs are opened on the rotating member in a circular array with the center of the rotating member; a material pipe, which is arranged on the box body, one end of the material pipe is connected to the discharge port, and the other end of the material pipe extends to one side of the furrow opener.

[0080] In the above scheme, the transmission rod 10 plays a key role in the fertilization system of the strip-shaped composite planting and seeder. The transmission rod 10 is rotatably mounted on the fertilizer tank 3 and extends through the fertilizer applicator 8. This allows the transmission rod 10 to transmit power from the fertilizer tank 3 to the fertilizer applicator 8, ensuring its normal operation.

[0081] The fertilizer spreader 8 mainly consists of a housing 801, a rotating member 806, several fertilizer troughs 8061, and a feed pipe 802. The housing 801 is provided with a feed port 805 and a discharge port 804. The feed port 805 is used to receive fertilizer delivered from the fertilizer box 3, and the discharge port 804 discharges the fertilizer into the feed pipe 802, and then transports it to the side of the furrow opener 21 for fertilization.

[0082] The rotating member 806 is rotatably disposed within the housing 801 and is mounted on the transmission rod 10. The transmission rod 10 drives the rotating member 806 to rotate, thereby driving the fertilizer trough 8061 to perform regular movement. A plurality of fertilizer troughs 8061 are arranged on the rotating member 806 in a circular array with the center of the rotating member 806, so that the fertilizer applicator 8 can achieve continuous and uniform fertilization. As the rotating member 806 rotates, the fertilizer troughs 8061 are sequentially connected to the feed port 805 to receive fertilizer, and then connected to the discharge port 804 at the appropriate time to discharge the fertilizer. The amount of fertilizer applied can be precisely controlled to ensure that the amount of fertilizer discharged by each fertilizer trough 8061 is substantially the same, thereby improving the accuracy and stability of fertilization.

[0083] Feed pipe 802 is mounted on housing 801. One end is connected to discharge port 804, and the other end extends to the side of furrow opener 21. Feed pipe 802 accurately delivers fertilizer discharged from fertilizer applicator 8 to the furrow created by furrow opener 21, ensuring that the fertilizer is applied to the correct location. The material and diameter of feed pipe 802 should be selected based on the characteristics and flow rate of the fertilizer to ensure smooth fertilizer delivery and avoid blockage.

[0084] The transmission rod 10 and the fertilizer applicator 8 cooperate to achieve efficient and precise fertilization. The transmission function of the transmission rod 10 and the design of the internal rotating member 806 and the fertilizer trough 8061 of the fertilizer applicator 8 make the fertilization process more automated and precise, providing a suitable fertilizer supply for the growth of crops, and helping to improve the yield and quality of crops.

[0085] Furthermore, the beating member includes: a disc, which is slidably mounted on the transmission rod, and the disc is located in the box body, and the side of the disc away from the rotating member is arranged on the protrusion; an elastic member, one end of which abuts on the disc, and the other end abuts on the rotating member, and the elastic member is used to provide a force for the disc to move away from the rotating member; a baffle rod, which is arranged on the box body, one end of the baffle rod extends into the box body and abuts on the side of the disc and the protrusion, and after the baffle rod abuts on the surface of the protrusion, the baffle rod squeezes the disc toward the side of the rotating member; there are several beating rods, and the beating ends are located on the beating rods. The number of beating rods is the same as the number of fertilizer troughs, and the beating rod has a cutting part, which is used to chop up the agglomerated fertilizer.

[0086] In the above scheme, the material-beating member 9 is mainly composed of a disc 902, an elastic member 904, a blocking rod 803 and a material-beating rod 901. The disc 902 is slidably mounted on the transmission rod 10 and is located in the box body 801. The sliding of the disc 902 on the transmission rod 10 enables it to move under certain circumstances, thereby realizing the function of beating the material. One end of the elastic member 904 abuts on the disc 902, and the other end abuts on the rotating member 806. The function of the elastic member 904 is to provide a force for the disc 902 to move away from the rotating member 806. Under normal circumstances, the elastic member 904 is in a natural state, so that a certain distance is maintained between the disc 902 and the rotating member 806. When it is necessary to beat the material, the pressure exerted by the external force on the elastic member 904 causes the disc 902 to move toward the rotating member 806. A blocking rod 803 is mounted on the housing 801, with one end extending into the housing 801 and contacting the side of the disc 902 and the protrusion 903. When the fertilizer spreader 8 is in operation, the blocking rod 803 contacts the disc 902 and the protrusion 903 as the fertilizer spreader 8 moves. Once the blocking rod 803 contacts the surface of the protrusion 903, it presses the disc 902 toward the rotating member 806. This squeezing action forces the disc 902 toward the rotating member 806, thereby triggering the action of the driving rod 901.

[0087] There are several beating rods 901, each with a beating end 9011 located on each rod. The number of beating rods 901 is the same as the number of fertilizer troughs 8061, ensuring that each fertilizer trough 8061 is effectively fed. The beating rods 901 have a cutting portion for breaking up clumped fertilizer. When the disc 902 is pressed by the blocking rod 803 toward the rotating member 806, the beating end 9011 of the beating rod 901 extends into the fertilizer trough 8061, using the cutting portion to break up clumped fertilizer. The cutting portion is sufficiently sharp and strong to effectively break up fertilizer lumps of various hardnesses.

[0088] In summary, the various components of the dispersing member 9 cooperate with each other to achieve the function of breaking up fertilizer clumps. The coordinated operation of the disc 902, elastic member 904, retaining rod 803, and dispersing rod 901 enables the fertilizer applicator 8 to automatically disperse fertilizer clumps when encountering fertilizer clumps, ensuring the continuity and stability of the fertilization operation and providing a reliable fertilizer supply for crop growth.

[0089] Furthermore, the furrow opener includes: a plurality of furrowing discs, which are all rotatably arranged on one side of the bottom of the frame; a plurality of fertilizer plowshares, which are all spaced apart and arranged on the bottom of the frame, and a material pipe is arranged on one side of the furrowing disc and / or the fertilizer plowshare.

[0090] In the above scheme, first, there are a plurality of furrowing discs 212, all of which are rotatably arranged on one side of the bottom of the frame 1, so that the furrowing discs 212 can cut into the soil more smoothly during operation, reduce resistance, and improve furrowing efficiency. The number of furrowing discs 212 can be adjusted according to actual planting needs to adapt to different working widths and soil conditions. The setting of multiple furrowing discs 212 can open multiple furrows at the same time, which provides convenience for subsequent fertilization and sowing. Secondly, there are also a plurality of fertilizer plowshares 211, which are arranged at intervals at the bottom of the frame 1. The function of the fertilizer plowshare 211 is to provide a channel for the discharge of fertilizer while opening the furrow. The fertilizer plowshares 211 arranged at intervals can ensure that the fertilizer can be evenly distributed in the furrow, thereby improving the effect of fertilization. The shape and size of the fertilizer plowshare 211 can be optimized according to the characteristics of the fertilizer and the soil conditions to ensure that the fertilizer can enter the soil smoothly. Finally, a feed pipe 802 is positioned on one side of the furrowing disc 212 and / or the fertilizer plowshare 211. The function of the feed pipe 802 is to guide the fertilizer discharged from the fertilizer applicator 8 into the furrow created by the furrow opener 21. The position of the feed pipe 802 can be adjusted based on actual conditions to ensure that the fertilizer accurately falls into the furrow. The material and diameter of the feed pipe 802 can be selected based on the characteristics and flow rate of the fertilizer to ensure smooth fertilizer delivery.

[0091] In summary, the various components of the furrow opener 21 cooperate with each other to complete the tasks of furrowing and fertilizing. The rotational design of the furrow opener 212, the spacing of the fertilizing plowshares 211, and the rational arrangement of the feed pipe 802 make the furrow opener 21 more efficient and accurate during operation, providing a strong guarantee for the normal operation of the entire strip composite planting seeder.

[0092] Furthermore, the fertilizer applicator also includes: an adjusting member, which is slidably arranged in the box body and located at the discharge port, and the adjusting member is used to block or cancel the blockage of the discharge port.

[0093] In the above scheme, the adjusting member 11 is slidably arranged in the housing 801 of the fertilizer applicator 8 and is located at the discharge port 804. Its main function is to be able to block or cancel the blockage of the discharge port 804 according to actual needs. When it is necessary to control the discharge of fertilizer, the adjusting member 11 can slide to the position of the discharge port 804 and block the discharge port 804. In this way, the discharge of fertilizer can be suspended under certain circumstances. For example, when the seed drill needs to temporarily stop the fertilization operation, or when the amount of fertilizer needs to be adjusted due to special terrain or soil conditions, the discharge port 804 can be blocked in time by the adjusting member 11 to achieve precise control of the fertilization process. When it is necessary to continue fertilizing, the adjusting member 11 can slide away from the discharge port 804, cancel the blockage of the discharge port 804, and allow the fertilizer to be discharged smoothly from the fertilizer applicator 8 and enter the groove opened by the furrow opener 21. This flexible adjustment method enables the fertilizer applicator 8 to adapt to different planting environments and fertilization requirements, thereby improving the accuracy and efficiency of fertilization.

[0094] Furthermore, the sowing devices are provided in a plurality of ways, and the plurality of sowing devices are arranged at intervals on the frame. The sowing devices include: a drum frame provided on the frame; a sowing drum rotatably provided on the drum frame, and the sowing drum has a plurality of sowing parts in the circumferential direction; an air-suction seeder provided on one side of the sowing drum; an electric fan provided on the drum frame, the electric fan being connected to the air-suction seeder, and the electric fan being used to form a negative pressure in the air-suction seeder; a seed storage box provided on the drum frame, the seed storage box being used to store seeds, and the seed storage box being connected to the air-suction seeder.

[0095] In the above scheme, the sowing device 5 plays a key role in the strip composite planting seeder, ensuring that seeds can be accurately and evenly sown on the soil. There are several sowing devices 5, which are arranged at intervals on the frame 1. Such a layout can adapt to different planting needs and working widths. First, the sowing device 5 includes a roller frame 505, which is firmly set on the frame 1 and provides stable support for components such as the sowing roller 501. The design of the roller frame 505 should have sufficient strength and stability to withstand various forces and vibrations during the sowing process. The sowing roller 501 is rotatably set on the roller frame 505 and is the core component of the sowing device 5. Several sowing parts 502 are distributed around the circumference of the sowing roller 501. The rotation of the sowing roller 501 is driven by the power system of the seeder. During the rotation process, the sowing parts 502 can take seeds out of the seed storage box 503 and accurately place them on the soil. The rotation speed and rotation direction of the sowing roller 501 can be adjusted according to actual conditions to control the speed and density of sowing.

[0096] The air-suction seeder 504 is arranged on one side of the sowing drum 501, and it works in conjunction with the electric fan 506 and the seed storage box 503. The electric fan 506 is arranged on the drum frame 505 and is connected to the air-suction seeder 504. Through the operation of the electric fan 506, the air-suction seeder 504 can form a negative pressure. Under the action of the negative pressure, the air-suction seeder 504 can suck seeds from the seed storage box 503 and accurately transfer the seeds to the sowing member 502 on the sowing drum 501. The air-suction sowing method has the advantages of high sowing accuracy and strong adaptability, and can effectively avoid blockage and waste of seeds. The seed storage box 503 is arranged on the drum frame 505 for storing seeds. The capacity of the seed storage box 503 can be designed according to the planting area and seed dosage to ensure that there is a sufficient supply of seeds during the sowing process. The seed storage box 503 is communicated with the air-suction seeder 504 so that seeds can smoothly enter the air-suction seeder 504 from the seed storage box 503. The structure of the seed storage box 503 should be convenient for adding and cleaning seeds, while ensuring the fluidity and stability of the seeds.

[0097] In summary, the various components of the sowing device 5 cooperate with each other to accomplish the task of sowing seeds. The coordinated operation of the drum frame 505, sowing drum 501, air-suction seeder 504, electric blower 506, and seed storage box 503 enables the sowing device 5 to achieve efficient and precise sowing operations, laying a good foundation for crop growth. This sowing device 5 not only improves sowing quality and efficiency but also adapts to different planting environments and seed types.

[0098] Furthermore, it also includes: a drip irrigation rack, which is arranged on the frame and located between the fertilizer box and the sowing device, and is used for installing a drip irrigation pipe.

[0099] In the above scheme, the placement of the drip irrigation rack 4 behind the fertilizer tank 3 allows the drip irrigation pipe to be laid immediately after fertilization. Drip irrigation enables precise water supply, which, in conjunction with fertilizer application, better meets the water and fertilizer needs of crop growth. Drip irrigation can be precisely adjusted to the water requirements of different crops, avoiding the water waste associated with traditional irrigation methods and improving water utilization efficiency.

[0100] On the other hand, the drip irrigation rack 4 is located before the sowing device 5. In this way, after sowing, the drip irrigation pipe has been laid in place, which can provide the seeds with the required moisture in time, promoting seed germination and growth. Especially for some crops with high water requirements, drip irrigation can provide them with a stable water supply during the critical period, improving the emergence rate and growth quality of the crops.

[0101] The main function of the drip irrigation rack 4 is to install drip irrigation pipes. Its structural design facilitates the installation and securing of the drip irrigation pipes, ensuring they do not loosen or fall off during seed drill operation. The drip irrigation rack 4 can be adjusted to suit different planting requirements and drip irrigation pipe specifications, adapting to various operating environments. In short, the addition of the drip irrigation rack 4 adds a significant functional module to the strip-type composite planting seeder, integrating sowing, fertilization, and irrigation, and improving the overall efficiency of agricultural production.
