[0022] 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.

[0023] Reference Figure 1 to Figure 8 , which is an embodiment of the present invention, proposes a strip composite planting seeder, including a frame 1 and a furrowing and fertilizing device 2, a sowing device 5 and a covering device 6 which are sequentially arranged on the frame 1, wherein the furrowing and fertilizing device 2 includes: a furrowing device 21, which has a plurality of furrowing devices 21, and the plurality of furrowing devices 21 are all 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 fertilizer applicator 8, which has a plurality of fertilizer applicators, and each fertilizer applicator 8 has a feed port 805 and a discharge port 80 4, each feed port 805 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 805 in sequence, and each discharge port 804 corresponds to a furrow opener 21; a material beating member 9 is slidably arranged in the fertilizer applicator 8, and the material beating member 9 has a plurality of material beating ends 9011, and each material beating end 9011 extends into a fertilizer trough 8061, and the material beating member 9 is used to break up the agglomerated fertilizer.

[0024] In the above scheme, multiple furrow openers 21 in the furrow fertilization device are evenly distributed in front of the frame 1. The shape and size of the furrow opener 21 can be designed according to actual planting needs to ensure that a furrow with appropriate depth and width can be opened on the land. The fertilizer box 3 is firmly mounted on the frame 1 and adopts a large-capacity design to meet the fertilizer needs of large-scale planting. The positions and numbers of the multiple feed ports 301 at the bottom of the fertilizer box 3 correspond to the feed port 805 of the fertilizer applicator 8, ensuring that the fertilizer can be smoothly transported from the fertilizer box 3 to the fertilizer applicator 8.

[0025] There are also multiple fertilizer applicators 8, each of which is equipped with a feed port 805 and a discharge port 804. The feed port 805 is connected to the discharge port 301 of the fertilizer box 3, so that the fertilizer can accurately enter the fertilizer applicator 8. After the fertilizer applicator 8 is started, the multiple fertilizer troughs 8061 inside the fertilizer applicator 8 are sequentially connected to the feed port 805 to achieve quantitative discharge of fertilizer, accurately control the amount of fertilizer, and improve the accuracy and stability of fertilization. Each discharge port 804 corresponds to a furrow opener 21, ensuring that the fertilizer can be accurately discharged into the furrow opened by the furrow opener 21, providing sufficient nutrients for the crops.

[0026] The material-beating member 9 is slidably disposed in the fertilizer applicator 8 and has a plurality of material-beating ends 9011. When fertilizer agglomerates appear in the fertilizer applicator 8, the material-beating member 9 can slide flexibly in the fertilizer applicator 8 and break up the agglomerated fertilizer through the material-beating ends 9011. The material-beating member 9 can be driven by a motor or a hydraulic system to realize automatic material-beating, thereby improving work efficiency and reducing manual intervention.

[0027] The sowing device 5 is mounted on the frame 1 and is located behind the furrowing and fertilizing device 2, which can ensure that the sowing depth and spacing of the seeds are uniform. At the same time, the sowing device 5 can be adjusted according to different crop requirements to adapt to the sowing requirements of corn and soybean strip interplanting mode.

[0028] The soil covering device 6 is installed on the frame 1 and is located behind the sowing device 5. The function of the soil covering device 6 is to cover the seeds after sowing with soil, provide a good growth environment for the seeds, and ensure that the seeds can germinate and grow smoothly. The soil covering device 6 adopts an adjustable design and can be adjusted according to different soil conditions and sowing depths, thereby improving the effect and adaptability of soil covering.

[0029] When the strip composite planting seeder of the present invention is actually used, the fertilizer is first loaded into the fertilizer box 3, and then the seeds are loaded into the sowing device 5. After the seeder is started, the furrow opener 21 opens a furrow on the land, and the fertilizer in the fertilizer box 3 enters the fertilizer applicator 8 through the discharge port 301, and the fertilizer applicator 8 discharges the fertilizer quantitatively into the furrow opened 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 agglomerated fertilizer appears in the fertilizer applicator 8, the material breaking member 9 will automatically break up the agglomerated fertilizer to ensure the smooth progress of the fertilization operation.

[0030] 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 agglomeration through the material beating part 9, ensuring the smooth progress of fertilization operation.

[0031] Furthermore, it also includes: a transmission rod 10, which is rotatably arranged on the fertilizer box 3, and the transmission rod 10 passes through the fertilizer applicator 8; the fertilizer applicator 8 includes: a box body 801, and a feed port 805 and a discharge port 804 are both opened on the box body 801; a rotating member 806, which is rotatably arranged in the box body 801, and the rotating member 806 is arranged on the transmission rod 10, and the transmission rod 10 is used to drive the rotating member 806 to rotate; a plurality of fertilizer troughs 8061 are opened on the rotating member 806 in a circular array with the center of the rotating member 806; a material pipe 802, which is arranged on the box body 801, one end of the material pipe 802 is connected to the discharge port 804, and the other end of the material pipe 802 extends to one side of the furrow opener 21.

[0032] In the above scheme, the transmission rod 10 plays a key transmission role in the fertilization system of the entire strip composite planting seeder. The transmission rod 10 is rotatably arranged on the fertilizer box 3 and passes through the fertilizer applicator 8. The transmission rod 10 can transmit power from the fertilizer box 3 to the inside of the fertilizer applicator 8, so that the fertilizer applicator 8 can operate normally.

[0033] The fertilizer spreader 8 is mainly composed of a box body 801, a rotating member 806, a plurality of fertilizer troughs 8061 and a material pipe 802. The box body 801 is provided with a feed port 805 and a discharge port 804. The feed port 805 is used to receive fertilizers delivered from the fertilizer box 3, and the discharge port 804 discharges the fertilizers into the material pipe 802, and then delivers them to the side of the furrow opener 21 for fertilization.

[0034] The rotating member 806 is rotatably arranged in 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 move regularly. 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 trough 8061 is sequentially connected with the feed port 805 to receive fertilizer, and then connected with the discharge port 804 at an appropriate time to discharge the fertilizer. The amount of fertilizer can be accurately controlled to ensure that the amount of fertilizer discharged from each fertilizer trough 8061 is basically the same, thereby improving the accuracy and stability of fertilization.

[0035] The material pipe 802 is arranged on the box body 801, one end of which is connected to the discharge port 804, and the other end of which extends to one side of the furrow opener 21. The function of the material pipe 802 is to accurately transport the fertilizer discharged by the fertilizer applicator 8 to the furrow opened by the furrow opener 21 to ensure that the fertilizer can be applied to the correct position. The material and diameter of the material pipe 802 should be selected according to the characteristics and flow rate of the fertilizer to ensure smooth transportation of the fertilizer and avoid blockage.

[0036] The transmission rod 10 and the fertilizer applicator 8 cooperate with each other to achieve efficient and accurate fertilization. The transmission function of the transmission rod 10 and the design of the internal rotating member 806 and the fertilizer slot 8061 of the fertilizer applicator 8 make the fertilization process more automated and accurate, provide a suitable fertilizer supply for the growth of crops, and help improve the yield and quality of crops.

[0037] Furthermore, the material-beating member 9 includes: a disk 902, which is slidably mounted on the transmission rod 10, and the disk 902 is located in the box body 801, and the side of the disk 902 away from the rotating member 806 is arranged on the protrusion 903; an elastic member 904, one end of which abuts on the disk 902, and the other end abuts on the rotating member 806, and the elastic member 904 is used to provide a force for the disk 902 to be away from the rotating member 806; a stopper 803, which is arranged on the box body 801, and the stopper 80 One end of the material-beating rod 901 extends into the box body 801 and abuts against the side of the disc 902 and the protrusion 903. After the blocking rod 803 abuts against the surface of the protrusion 903, the blocking rod 803 presses the disc 902 toward the rotating member 806. The material-beating rod 901 has a plurality of material-beating ends 9011 located on the material-beating rod 901. The number of the material-beating rods 901 is the same as the number of the fertilizer troughs 8061. The material-beating rod 901 has a cutting portion, which is used to cut the agglomerated fertilizer.

[0038] In the above scheme, the material beating member 9 is mainly composed of a disc 902, an elastic member 904, a stop rod 803 and a material beating rod 901. The disc 902 is slidably sleeved on the transmission rod 10 and is located in the box 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. 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 external force will exert pressure on the elastic member 904, so that the disc 902 moves to the side of the rotating member 806. The blocking rod 803 is arranged on the box body 801, and one end of the blocking rod 803 extends into the box body 801 and abuts against the side of the disc 902 and the protrusion 903. When the fertilizer applicator 8 is in operation, the blocking rod 803 will contact the disc 902 and the protrusion 903 as the fertilizer applicator 8 moves. After the blocking rod 803 abuts against the surface of the protrusion 903, it will squeeze the disc 902 toward the side of the rotating member 806. This squeezing action makes the disc 902 approach the rotating member 806, thereby triggering the action of the punching rod 901.

[0039] There are several beating rods 901, and beating ends 9011 are located on the beating rods 901. The number of beating rods 901 is the same as the number of fertilizer troughs 8061, which can ensure that each fertilizer trough 8061 can be effectively beaten. The beating rod 901 has a cutting part, which is used to break up the agglomerated fertilizer. When the disc 902 is squeezed by the blocking rod 803 and moves toward the rotating member 806, the beating end 9011 of the beating rod 901 will extend into the fertilizer trough 8061, and the agglomerated fertilizer will be broken up by the cutting part. The cutting part has sufficient sharpness and strength, and can effectively break up fertilizer agglomerates of various hardnesses.

[0040] In summary, the various components of the material-beating member 9 cooperate with each other to achieve the function of breaking up the lumped fertilizer. The coordinated work of the disc 902, the elastic member 904, the blocking rod 803 and the material-beating rod 901 enables the fertilizer spreader 8 to automatically beat the fertilizer when encountering fertilizer lumps, thereby ensuring the continuity and stability of the fertilization operation and providing a reliable fertilizer supply for the growth of crops.

[0041] Furthermore, the furrow opener 21 includes: a furrowing disc 212, which has a plurality of them, and the plurality of furrowing discs 212 are rotatably arranged on one side of the bottom of the frame 1; a fertilizer plowshare 211, which has a plurality of them, and the plurality of fertilizer plowshares 211 are arranged at intervals on the bottom of the frame 1, and the material pipe 802 is arranged on one side of the furrowing disc 212 and / or the fertilizer plowshare 211.

[0042] In the above scheme, first, there are several furrowing discs 212, all of which are rotatably arranged at 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 operating 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 several fertilizer plowshares 211, which are arranged at intervals at the bottom of the frame 1. The function of the fertilizer plowshares 211 is to provide a channel for the discharge of fertilizer while furrowing. The fertilizer plowshares 211 arranged at intervals can ensure that the fertilizer can be evenly distributed in the furrows, thereby improving the effect of fertilization. The shape and size of the fertilizer plowshares 211 can be optimized and designed according to the characteristics of the fertilizer and the soil conditions to ensure that the fertilizer can enter the soil smoothly. Finally, the feed pipe 802 is arranged 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 by the fertilizer applicator 8 to the furrow opened by the furrow opener 21. The position of the feed pipe 802 can be adjusted according to actual conditions to ensure that the fertilizer can accurately fall into the furrow. The material and diameter of the feed pipe 802 can be selected according to the characteristics and flow rate of the fertilizer to ensure smooth transportation of the fertilizer.

[0043] In summary, the various components of the furrow opener 21 cooperate with each other to complete the tasks of furrowing and fertilizing. The rotation design of the furrow opener 212, the spacing setting of the fertilizing plowshare 211 and the reasonable arrangement of the material pipe 802 make the furrow opener 21 more efficient and accurate when working, providing a strong guarantee for the normal operation of the entire strip composite planting seeder.

[0044] Furthermore, the fertilizer applicator 8 also includes: an adjusting member 11 slidably disposed in the box body 801 and located at the discharge port 804 , and the adjusting member 11 is used to block or cancel the blockage of the discharge port 804 .

[0045] 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 encountering special terrain and soil conditions and the amount of fertilizer needs to be adjusted, 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, so that the fertilizer can be smoothly discharged 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, and improves the accuracy and efficiency of fertilization.

[0046] Furthermore, there are several sowing devices 5, and the several sowing devices 5 are arranged on the frame 1 at intervals. The sowing device 5 includes: a drum frame 505, which is arranged on the frame 1; a sowing drum 501, which is rotatably arranged on the drum frame 505, and the sowing drum 501 has several sowing members 502 in the circumferential direction; an air-suction seeder 504, which is arranged on one side of the sowing drum 501; an electric fan 506, which is arranged on the drum frame 505, and the electric fan 506 is connected to the air-suction seeder 504, and the electric fan 506 is used to form a negative pressure on the air-suction seeder 504; a seed storage box 503, which is arranged on the drum frame 505, and the seed storage box 503 is used to store seeds, and the seed storage box 503 is connected to the air-suction seeder 504.

[0047] In the above scheme, the sowing device 5 plays a key role in the strip composite planting seeder to ensure that the seeds can be accurately and evenly sown into the land. There are several sowing devices 5, which are arranged on the frame 1 at intervals. Such a layout can adapt to different planting needs and working widths. First, the sowing device 5 includes a drum frame 505, which is firmly arranged on the frame 1 to provide stable support for components such as the sowing drum 501. The design of the drum frame 505 should have sufficient strength and stability to withstand various forces and vibrations during the sowing process. The sowing drum 501 is rotatably arranged on the drum frame 505 and is the core component of the sowing device 5. Several sowing pieces 502 are distributed on the circumference of the sowing drum 501. The rotation of the sowing drum 501 is driven by the power system of the seeder. During the rotation process, the sowing piece 502 can take out the seeds from the seed storage box 503 and accurately put them on the land. The rotation speed and rotation direction of the sowing drum 501 can be adjusted according to actual conditions to control the speed and density of sowing.

[0048] The air-suction seeder 504 is arranged on one side of the sowing drum 501, and it cooperates with the electric fan 506 and the seed storage box 503. The electric fan 506 is arranged on the drum frame 505, and the electric fan 506 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 absorb 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 the 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 the amount of seeds used to ensure that there is enough seed supply during the sowing process. The seed storage box 503 is communicated with the air-suction seeder 504, so that the 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, and the fluidity and stability of the seeds should be guaranteed at the same time.

[0049] In summary, the various components of the sowing device 5 cooperate with each other to complete the task of sowing seeds. The coordinated work of the drum frame 505, the sowing drum 501, the air-suction seeder 504, the electric fan 506 and the seed storage box 503 enables the sowing device 5 to achieve efficient and accurate sowing operations, laying a good foundation for the growth of crops.

The film spreading roller 703 is rotatably arranged on the connecting end 702, and its function is to unfold the film so that the film can be evenly covered on the land. The rotation of the film spreading roller 703 can be driven by the power system of the seeder, or an independent driving device can be used. During the film spreading process, the film spreading roller 703 should maintain a stable rotation speed and tension to ensure the film spreading effect. There are several film pressing wheels 704, which are symmetrically arranged at both ends of the support plate 701. The function of the film pressing wheels 704 is to press the two sides of the film into the soil to prevent the film from being blown up by the wind or damaged by external forces. The number and position of the film pressing wheels 704 can be adjusted according to the width of the film and the soil conditions to ensure that the film can be firmly covered on the land. The material of the film pressing wheels 704 should have a certain elasticity and wear resistance to adapt to different soil surfaces and working environments.

[0052] In summary, the various components of the film covering device 7 cooperate with each other to complete the land film covering task. The coordinated work of the support plate 701, the film spreading roller 703 and the film pressing wheel 704 enables the film covering device 7 to achieve efficient and stable film covering operation, providing good environmental conditions for the growth of crops.

[0053] Further, the soil covering device 6 comprises: a first soil covering disc 601, which has a plurality of first soil covering discs 601, which are rotatably arranged at the bottom of the frame 1 and located outside the film pressing wheel 704, and the first soil covering disc 601 is used to push soil in the direction of the film pressing wheel 704; an upper soil cylinder 603, which is rotatably arranged on the frame 1, and is located at the rear end of the frame 1, and the upper soil cylinder 603 is hollow inside, and a soil outlet is provided on the outer wall of the upper soil cylinder 603, and the upper soil cylinder 603 is used to cover the surface of the film with soil; a second soil covering disc 602, which has a plurality of second soil covering discs 602, which are symmetrically arranged on both sides of the upper soil cylinder 603, and the second soil covering disc 602 is used to push soil into the upper soil cylinder 603.

The soil covering device 6 is mainly composed 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 plate 601 is to push soil in the direction of the film pressing wheel 704, cover the soil on both sides of the film, further fix the film, and also provide a certain covering layer for the seeds. The number of the first soil covering plates 601 can be adjusted according to actual needs to ensure that the covering effect is uniform. The rotation of the first soil covering plate 601 is driven by the power system of the seeder, and its rotation speed and angle can be optimized according to soil conditions and operation 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 an outlet is provided at intervals on the outer wall. The effect of the upper soil tube 603 is to cover the film surface with soil, providing a thicker covering layer for the seed. The rotation of the upper soil tube 603 can make the soil uniformly discharged from the soil outlet and covered on the film surface. The rotating speed of the upper soil tube 603 and the size of the soil outlet can be adjusted according to the fluidity and covering requirements of the soil to ensure that the covering effect is good. Several second covering plates 602 are symmetrically arranged on both sides of the upper soil tube 603. The effect of the second covering plate 602 is to push soil into the upper soil tube 603 to provide a continuous soil supply for the upper soil tube 603. The number and position of the second covering plate 602 can be adjusted according to the size and soil conditions of the upper soil tube 603 to ensure that the upper soil tube 603 can work normally. The rotation of the second covering plate 602 is also driven by the power system of the seed drill, and its rotating speed and angle can match the working requirements of the upper soil tube 603.

[0055] The pressing assembly 604 is arranged on the frame 1, and is located on the side away from the upper soil cylinder 603. The function of the pressing assembly 604 is to compact the soil, so that the soil covers the seeds and the film more tightly, reduce the air permeability of the soil, maintain the moisture and temperature of the soil, and facilitate the germination and growth of the seeds. The pressing assembly 604 can be in different forms, such as roller type, plate type, etc., and its pressure and compaction degree can be adjusted according to the soil conditions and seed requirements.

[0056] In summary, the various components of the soil covering device 6 cooperate with each other to jointly complete the task of soil covering and compacting. The coordinated work of the first soil covering plate 601, the upper soil cylinder 603, the second soil covering plate 602 and the pressing component 604 enables the soil covering device 6 to achieve efficient and uniform soil covering operations, providing a good soil environment for the growth of crops. The soil covering device 6 not only improves the efficiency and quality of agricultural production, but also can adapt to different soil conditions and planting requirements, bringing more convenience and benefits to farmers.

[0057] Furthermore, the suppression assembly 604 includes: a plurality of swing rods 6044, which are hinged at intervals on the frame 1; a plurality of suppression wheels 6041, each of which is rotatably set on the other end of a swing rod 6044; a fixed rod 6043, which is set on the frame; a spring rod 6042, one end of which is slidably set on the fixed rod 6043 and the other point is hinged on the swing rod 6044, and the spring rod 6042 is used to provide force for the suppression wheel 6041 to stick close to the ground.

[0058] In the above scheme, the pressing component 604 plays an important role in the belt-shaped composite planting seeder, which can compact the soil and provide a good soil environment for the growth of seeds. The pressing component 604 is mainly composed of a swing rod 6044, a pressing wheel 6041, a fixing rod 6043 and a spring rod 6042.

[0059] First, a plurality of swinging rods 6044 are hingedly arranged on the frame at intervals. The number of swinging rods 6044 can be adjusted according to actual needs to ensure that the soil can be fully suppressed. The hinged design of the swinging rods 6044 enables them to swing freely within a certain range, so as to adapt to different terrains and soil conditions. When the seeder is traveling on uneven ground, the swinging rods 6044 can automatically adjust the angle according to the ups and downs of the ground to ensure that the pressing wheel 6041 always maintains good contact with the ground. There are a plurality of pressing wheels 6041, and each pressing wheel 6041 is rotatably arranged on the other end of a swinging rod 6044. The pressing wheels 6041 are the core components of the suppression assembly 604, which are in direct contact with the soil and compact the soil through their own weight and rotation. The number and size of the pressing wheels 6041 can be selected according to the working width of the seeder and the soil compaction requirements. The rotation design of the pressing wheel 6041 can reduce the friction between the soil and improve the suppression efficiency, and at the same time can also avoid excessive damage to the soil. The fixed rod 6043 is arranged on the frame to provide fixed support for the spring rod 6042. One end of the spring rod 6042 is slidably arranged on the fixed rod 6043, and the other end is hinged on the swing rod 6044. The function of the spring rod 6042 is to provide the pressing wheel 6041 with a force close 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.

[0060] Furthermore, it also includes: a drip irrigation frame 4, which is arranged on the frame 1, and the drip irrigation frame 4 is located between the fertilizer box 3 and the sowing device 5. The drip irrigation frame 4 is used to install a drip irrigation pipe.

[0061] In the above scheme, in the strip composite planting seeder, the provision of the drip irrigation rack 4 further improves the scientificity and efficiency of the planting process. The drip irrigation rack 4 is arranged on the frame 1 and is located between the fertilizer box 3 and the sowing device 5. The selection of this position has been carefully considered. On the one hand, the drip irrigation rack 4 is placed after the fertilizer box 3 so that after the fertilization operation is completed, the drip irrigation pipe can be laid immediately. Drip irrigation can achieve precise water supply, cooperate with the application of fertilizers, and better meet the needs of crop growth for water and fertilizer. The drip irrigation method can be accurately adjusted according to the water requirements of different crops, avoiding the waste of water resources in traditional irrigation methods and improving the utilization efficiency of water resources.

[0062] On the other hand, the drip irrigation rack 4 is located before the sowing device 5, so that after sowing, the drip irrigation pipe has been laid in place, which can provide the seeds with the required moisture in time to promote the germination and growth of the seeds. Especially for some crops with high water requirements, drip irrigation can provide them with a stable water supply during the critical period, improve the emergence rate and the growth quality of the crops.

[0063] The main function of the drip irrigation rack 4 is to install the drip irrigation pipe. Its structural design should facilitate the installation and fixation of the drip irrigation pipe to ensure that the drip irrigation pipe will not loosen or fall off during the operation of the seeder. The drip irrigation rack 4 can be adjusted according to different planting needs and drip irrigation pipe specifications to adapt to different operating environments. In short, the addition of the drip irrigation rack 4 adds an important functional module to the strip composite planting seeder, integrates sowing, fertilization and irrigation, and improves the comprehensive benefits of agricultural production.
