Description

Technical Field

[0001] The present invention belongs to the field related to agricultural machinery equipment, and more specifically, it is a three-axis rotary tillage fertilizing and seeding machine. Background Art

[0002] A fertilizing and seeding machine is an agricultural machine that applies fertilizers during the seeding process. It is usually composed of adding corresponding fertilizer discharging devices, fertilizer conveying pipes, fertilizing furrow openers and other components to a cereal drill or a row crop planter. This kind of machine can provide sufficient nutrition for seedlings at the same time, ensuring that the seedlings are neat and strong, and is one of the effective measures for increasing agricultural production.

[0003] The prior art CN103053251A discloses a fertilizing and seeding machine, including walking wheels, a container box and a hand push rod installed on the container box. A plurality of partition plates are horizontally arranged in the container box, and a plurality of circulation holes are evenly arranged on the partition plates. The bottom of the container box is provided with a sprinkling pipe, the sprinkling pipe is connected with a spray pipe, and a plurality of nozzles are arranged on the spray pipe. The bottom of the container box is connected with a walking frame through a spring steel plate, the bottom of the walking frame is movably connected with the walking wheels, the front end of the walking frame is connected with a rotary tillage roller through a movable bracket, and the rear end of the walking frame is connected with a plurality of brackets, and a combing blade perpendicular to the ground is arranged on each bracket; through the layers of partition plates and circulation holes, the mixing is more uniform. When the fertilizing and seeding machine works, through the vibration of the vibrator and the elastic action of the spring steel plate on the walking frame, the seeds and fertilizers in the container box are not adhered, which is beneficial to the spraying of the fertilizers and seeds from the sprinkling pipe and the spray pipe, and the spraying effect is good.

[0004] The above-mentioned equipment has certain deficiencies in the fertilizing and seeding operations. It adopts a single-axis structure design. When in use, due to a series of reasons such as operation rolling, soil compaction caused by the application of chemical fertilizers and pesticides, a lot of rain in autumn, and high soil humidity, when sowing, soil and weeds are piled up, and mud adheres to the seed discharging legs and the pressing rollers, resulting in the inability to sow smoothly; secondly, the environment where the seeds are located is not good, such as a low rate of soil crumbling, the phenomenon that wheat seedlings are pressed by large soil clods and do not emerge, the phenomenon that wheat seedlings are hanged due to straw buried in the soil, and the phenomenon of soil compaction after the pressing roller of the seeding machine presses, which will greatly reduce the use effect of the fertilizing and seeding machine and reduce the seed survival rate; at the same time, during the use of the above-mentioned equipment, its seeding structure is prone to blockage during the falling process of the seeds, making the seeds unable to be discharged normally, without a synchronous feeding structure, reducing the use effect of the fertilizing and seeding machine. Summary of the Invention

[0005] The purpose of the present invention is to provide a three-axis rotary tillage fertilizing and seeding machine, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. The traditional equipment adopts a single-axis structure design, which causes soil and weeds to accumulate during sowing, and soil to stick to the seed-dropping legs and the press roller, resulting in unsuccessful sowing.

[0008] 2. Secondly, the soil-breaking rate of the traditional equipment is low. Problems such as wheat seedlings being crushed by large soil clods and unable to emerge, wheat seedlings being strangled due to straw being buried in the soil, and soil hardening after being pressed by the press roller of the seeder will greatly reduce the use effect of the fertilizer seeder and the seed survival rate.

[0009] 3. At the same time, during the use of the above equipment, the sowing structure is prone to blockage during the seed dropping process, making the seeds unable to be discharged normally. Without a synchronous feeding structure, the use effect of the fertilizer seeder is reduced.

[0010] The object of the present invention can be achieved by the following technical solutions:

[0011] A three-axis rotary tillage fertilizer seeder includes a housing and a sowing hopper. The sowing hopper is fixedly installed on the upper outer surface of the housing. Inside the housing, a first cutter shaft, a second cutter shaft, and a third cutter shaft are sequentially movably installed. The first cutter shaft, the second cutter shaft, and the third cutter shaft are arranged side by side. Between the first cutter shaft and the second cutter shaft, several groups of seed-dropping legs are provided. Between the second cutter shaft and the third cutter shaft, a press roller is provided. A seeder is provided between the sowing hopper and the seed-dropping legs. On the outer surface of the second cutter shaft, several groups of short rotary tillage cutters are provided. The short rotary tillage cutters are located on one side of the seed-dropping legs. Inside the housing, an inclined surface clamping plate is installed above the press roller. The housing and the inclined surface clamping plate are fixedly connected through a clamping seat.

[0012] As a further technical solution of the present invention, several groups of seven-character cutters are fixedly installed on the outer surface of the first cutter shaft, and one end of the seven-character cutter is in an arc-shaped bent structure. The first cutter shaft and several groups of seven-character cutters are connected through a rotating disk. A connecting frame is provided at the rear ends of the housing and the sowing hopper. When the fertilizer seeder moves under the traction of a tractor, the seven-character cutters of the first cutter shaft contact the soil, and the soil is rotary tilled by the seven-character cutters. In addition to the rotary tillage effect, the seven-character cutters can also crush the residual straw and spread it deep under the soil layer, converting the straw into fertilizer for use.

[0013] As a further technical solution of the present invention, the first blade shaft, the second blade shaft, the pressing roller and the third blade shaft are all connected by a toothed chain structure. The outer surface of the short rotary blade is an arc structure, and the outer surface of the pressing roller is provided with a toothed structure. The second blade shaft is used to drive the short rotary blade to rotate. When the short rotary blade contacts the soil, the soil in the sowing layer is tilled for the second time, and the soil crushing rate is further improved, providing a better environment for the seeds and ensuring the germination rate. At the same time, because the short rotary blades on the second blade shaft are placed on both sides of the seeding legs, when the short rotary blades rotate, the soil and straw attached to the seeding legs are scraped to ensure smooth sowing. The pressing roller rolls the soil after sowing to compact the soil.

[0014] As a further technical solution of the present invention, the seven-shaped knife and the rotating disk are docked and fixed by a splicing card seat, and a plurality of groups of scraping knives are fixedly installed on the outer surface of the third knife shaft. When the pressing roller rotates, the plurality of groups of scraping knives are synchronously driven to rotate. The plurality of groups of scraping knives scrape the soil on the surface of the pressing roller and loosen the soil on the surface pressed by the pressing roller.

[0015] As a further technical solution of the present invention, a feeding pipe is fixedly installed at the lower end of the seeder, a rotating scraper is movably installed inside the seeder, the seeder and the seeder bucket are docked and fixed by a fixed base, and the quantitative feeding of seeds in the seeder bucket can be completed by the rotation of the rotating scraper in the seeder, and a certain number of seeds can be fed every time the rotating scraper rotates one circle.

[0016] As a further technical solution of the present invention, the seeder and the rotating scraper are movably connected via a rotating wheel, several groups of seeder wheels are connected via a docking rotating rod, one end of the docking rotating rod and the pressing roller are connected via a toothed chain structure. When the pressing roller rotates, the toothed chain structure is used to drive the docking rotating rod to rotate, and the docking rotating rod simultaneously drives several groups of wheels, so that the rotating wheel drives the rotating scraper, causing the rotating scraper to rotate in the seeder to complete the quantitative delivery of seeds.

[0017] As a further technical solution of the present invention, a material receiver is installed at the upper end of the seeding leg, and the seeding leg and the material receiver are movably connected, and a lifting hopper is installed on the inner side of the material receiver at the end of the seeding leg, and a feeding pipe is placed on the inner side of the material receiver. The seeds are fed into the material receiver by the feeding pipe. In order to avoid blockage of seeds during the feeding process, the seeding legs are set in an active state so that the seeding legs move up and down when in contact with the soil, and the seeding legs are used to drive the lifting hopper, so that the lifting hopper drives the seeds in the material receiver to move up and down, thereby avoiding seeds being blocked inside the material receiver.

[0018] As a further technical solution of the present invention, a limiting ring is sleeved on the outer surface of the seed metering leg, and the seed metering leg and the limiting ring are butt-jointed by threads. A protective pad is fixedly installed at the lower end of the seed metering leg, and a soil breaker is fixedly installed on one side of the seed metering leg. The setting of the soil breaker can reduce the resistance when the seed metering leg moves. At the same time, the protective pad plays a protective role in the bottom of the seed metering leg, and the setting of the limiting ring can limit the lifting range of the seed metering leg, so that it can be adaptively adjusted according to the soil conditions.

[0019] As a further technical solution of the present invention, a telescopic plate is movably installed at the lower end of the inclined surface clamping plate, and the inclined surface clamping plate and the telescopic plate are locked and fixed by a fastening bolt. A plurality of groups of tooth grooves for cooperating with the pressure roller are arranged at the lower end of the telescopic plate. With the setting of the tooth grooves, when the pressure roller rotates, the tooth-shaped structure on its surface can pass through the tooth grooves. At the same time, the obliquely arranged telescopic plate can clean the soil on the surface of the pressure roller, so that the pressure roller maintains a good use effect.

[0020] As a further technical solution of the present invention, a partition is arranged inside the sowing hopper, and feeding grooves are arranged on both sides of the partition inside the sowing hopper. Linkage members are fixedly installed on both sides of the outer housing. The linkage member is a housing structure, which is mainly used to protect the tooth chain structure of the equipment. In the case of good soil moisture, a fertilizer application leg is arranged in front of and below the seed metering leg, and a fertilizer applicator is added. Using the two feeding grooves, the common discharge of fertilizer and seeds is realized, and the fertilizer is placed below the seeds, which can make full use of chemical fertilizers and avoid the situation of burning seedlings.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. By setting the second cutter shaft, the third cutter shaft and the inclined surface clamping plate, when the three-axis rotary tillage fertilizing and sowing machine is used, in cooperation with the use of the first cutter shaft, it has a three-axis rotary tillage structure, improves the use effect of the fertilizing and sowing machine, and avoids the seed metering leg and the pressure roller from sticking with soil, weeds and mud, and has a synchronous cleaning structure;

[0023] During operation, the user docks the connecting frame with the tractor and places the seeds inside the sowing hopper. When the fertilizing and sowing machine moves under the drag of the tractor, the seven-shaped knives of the first cutter shaft come into contact with the soil, and the seven-shaped knives are used to perform rotary tillage on the soil. In addition to the rotary tillage function, the seven-shaped knives can also crush the remaining straw and spread it deep under the soil layer, converting the straw into fertilizer for use. Secondly, the tooth chain structure is used to make the first cutter shaft, the second cutter shaft, the pressing roller and the third cutter shaft rotate synchronously. The second cutter shaft drives the short rotary tillage knives to rotate. Since the short rotary tillage knives on the second cutter shaft are placed on both sides of the seed discharging leg, when the short rotary tillage knives rotate, they scrape the soil and straw attached to the seed discharging leg, preventing the soil and straw from adhering to the seed discharging leg, reducing the moving resistance of the seed discharging leg, and ensuring the smooth progress of sowing. The pressing roller is used to roll and press the soil after sowing to compact the soil. When the pressing roller is continuously used, a large amount of soil will adhere to the surface of the pressing roller, affecting its use effect. When the pressing roller rotates, it synchronously drives several groups of scraping knives to rotate. The several groups of scraping knives play the role of scraping the soil on the surface of the pressing roller and loosening the ground surface pressed by the pressing roller. At the same time, the telescopic plate can make the tooth-shaped structure on its surface pass through the tooth grooves when the pressing roller rotates by using the setting of the tooth grooves. At the same time, the inclined telescopic plate can clean the soil on the surface of the pressing roller, enabling the pressing roller to maintain a good use effect. The use height of the telescopic plate can be adjusted by using the fastening bolt in cooperation with the inclined clamping plate.

[0024] 2. By setting the seven-shaped knives and the short rotary tillage knives, when the three-axis rotary tillage, fertilizing and sowing machine is in use, it has multiple soil crushing structures, enabling the soil in the planting area to be fully crushed, keeping the soil soft during the planting process, and improving the sowing effect of the fertilizing and sowing machine.

[0025] During use, the first cutter shaft drives the seven-shaped knives to rotate. One end of the seven-shaped knife is designed with an arc-shaped bent structure, so that when the seven-shaped knives rotate, they can not only break the soil, but also cut the straw in the soil, thus completing the preliminary soil loosening operation. This step can break the cloddy soil. Secondly, due to the design of the tooth chain structure, the second cutter shaft and the third cutter shaft are synchronously driven to rotate. The second cutter shaft drives the short rotary tillage knives to rotate. When the short rotary tillage knives come into contact with the soil, the soil in the sowing layer is subjected to secondary rotary tillage, and the soil fragmentation rate is further improved, providing a better environment for the seeds and ensuring the emergence rate. After the pressing roller rolls and presses the soil after sowing, several groups of scraping knives can loosen the ground surface pressed by the pressing roller.

[0026] 3. By setting the lifting hopper, when the three-axis rotary tillage, fertilizing and sowing machine is in use, the use of the seed discharging leg is optimized, and it has a synchronous feeding structure, avoiding the seeds from being blocked inside the seed discharging leg and improving its sowing stability.

[0027] During operation, seeds are put into the feeder through the feeding pipe. To prevent the seeds from being blocked during the feeding process, by setting the seed discharging legs in an active state, the seed discharging legs move up and down when contacting the soil, and the seed discharging legs are used to drive the lifting hopper, so that the lifting hopper drives the seeds in the feeder to move up and down, thus preventing the seeds from being blocked inside the feeder. Secondly, the setting of the soil breaker can reduce the resistance when the seed discharging legs move, and at the same time, the protective pad plays a protective role for the bottom of the seed discharging legs, while the setting of the limit ring can limit the lifting range of the seed discharging legs, enabling it to make adaptive adjustments according to the soil conditions.

[0036] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific embodiments, structures, features and their effects of the present invention as follows.

[0037] like Figure 1 As shown, a three-axis rotary tillage fertilization seeder comprises an outer shell 1 and a seeding bucket 6, wherein the seeding bucket 6 is fixedly mounted on the outer surface of the upper end of the outer shell 1, and a first cutter shaft 14, a second cutter shaft 12 and a third cutter shaft 2 are movably mounted in sequence inside the outer shell 1, wherein the first cutter shaft 14, the second cutter shaft 12 and the third cutter shaft 2 are arranged side by side, a plurality of groups of seeding legs 13 are arranged between the first cutter shaft 14 and the second cutter shaft 12, and a pressing roller 10 is arranged between the second cutter shaft 12 and the third cutter shaft 2; a seeder 9 is arranged between the seeding bucket 6 and the seeding legs 13, a plurality of groups of short rotary tillage knives 11 are arranged on the outer surface of the second cutter shaft 12, and the short rotary tillage knives 11 are located on one side of the seeding legs 13, and an inclined clamping plate 16 is installed above the pressing roller 10 inside the outer shell 1, and the outer shell 1 and the inclined clamping plate 16 are fixed by docking with a clamping seat.

[0038] To solve the problem of poor soil crushing effect of the seeder, Figure 3 As shown, a plurality of groups of seven-shaped knives 5 are fixedly mounted on the outer surface of the first knife shaft 14, and one end of the seven-shaped knives 5 is in an arc-shaped bent structure. The first knife shaft 14 and the plurality of groups of seven-shaped knives 5 are connected by a rotating disk 18. A connecting frame 7 is provided at the rear end of the outer shell 1 and the seeding bucket 6. When the fertilizer seeder moves under the towing of the tractor, the seven-shaped knives 5 of the first knife shaft 14 come into contact with the soil, and the soil is rotary tilled by the seven-shaped knives 5. In addition to the function of rotary tillage, the seven-shaped knives 5 can also crush the remaining straw, scatter it and bury it deep under the soil layer, and convert the straw into fertilizer for use.

[0039] like Figure 2 As shown, the first blade shaft 14, the second blade shaft 12, the pressing roller 10 and the third blade shaft 2 are all connected through a toothed chain structure. The outer surface of the short rotary blade 11 is an arc structure, and the outer surface of the pressing roller 10 is provided with a toothed structure. The second blade shaft 12 is used to drive the short rotary blade 11 to rotate. When the short rotary blade 11 contacts the soil, the soil in the sowing layer is rotary tilled for the second time, and the soil crushing rate is further improved, providing a better environment for the seeds and ensuring the germination rate. At the same time, because the short rotary blades 11 on the second blade shaft 12 are placed on both sides of the seeding legs 13, when the short rotary blades 11 rotate, the soil and straw attached to the seeding legs 13 are also scraped to ensure smooth sowing, and the pressing roller 10 rolls the soil after sowing to compact the soil.

[0040] To solve the problem of poor looseness of the single-axis structure of the seed drill, Figure 2 As shown, the seven-shaped knife 5 and the rotating disk 18 are fixed together by a splicing seat 17, and a plurality of groups of scraping knives 3 are fixedly installed on the outer surface of the third knife shaft 2. When the pressing roller 10 rotates, the plurality of groups of scraping knives 3 are synchronously driven to rotate. The plurality of groups of scraping knives 3 scrape the soil on the surface of the pressing roller 10 and loosen the soil on the surface pressed by the pressing roller 10.

[0041] As Figure 4 shown, a feeding pipe 20 is fixedly installed at the lower end of the seeder 9. A rotary scraper 19 is movably installed inside the seeder 9. The seeder 9 and the seeding hopper 6 are butt-jointed and fixed through a fixed card seat 22. By rotating the rotary scraper 19 inside the seeder 9, quantitative feeding of the seeds in the seeding hopper 6 can be completed. Each rotation of the rotary scraper 19 can feed a certain number of seeds.

[0042] The seeder 9 and the rotary scraper 19 are movably connected through a runner 21. The runners 21 of several groups of seeders 9 are connected through a docking rod 8. One end of the docking rod 8 and the press roller 10 are driven by a chain structure. When the press roller 10 rotates, the docking rod 8 is driven to rotate by the chain structure. The docking rod 8 simultaneously drives several groups of runners 21, so that the runners 21 drive the rotary scraper 19, causing the rotary scraper 19 to rotate inside the seeder 9 and completing the quantitative feeding of the seeds.

[0043] To solve the problem of blockage of the seed metering structure of the seeder, as Figure 5 shown, a material receiver 27 is installed at the upper end of the seed discharging leg 13. The seed discharging leg 13 and the material receiver 27 are movably butted. And a lifting hopper 25 is installed inside the material receiver 27 at the end of the seed discharging leg 13. The feeding pipe 20 is placed inside the material receiver 27. The seeds are fed into the material receiver 27 by the feeding pipe 20. To avoid blockage of the seeds during feeding, by setting the seed discharging leg 13 in a movable state, the seed discharging leg 13 moves up and down when contacting the soil. The seed discharging leg 13 drives the lifting hopper 25, so that the lifting hopper 25 drives the seeds in the material receiver 27 to move up and down, thereby avoiding blockage of the seeds inside the material receiver 27.

[0044] A limiting ring 26 is sleeved on the outer surface of the seed discharging leg 13, and the seed discharging leg 13 and the limiting ring 26 are butted through threads. A protective pad 23 is fixedly installed at the lower end of the seed discharging leg 13. A soil breaker 24 is fixedly installed on one side of the seed discharging leg 13. The setting of the soil breaker 24 can reduce the resistance when the seed discharging leg 13 moves. At the same time, the protective pad 23 protects the bottom of the seed discharging leg 13. The setting of the limiting ring 26 can limit the lifting range of the seed discharging leg 13, enabling it to be adaptively adjusted according to the soil conditions.

[0045] As Figure 6As shown in the figure, a telescopic plate 29 is movably installed at the lower end of the inclined surface clamping plate 16. The inclined surface clamping plate 16 and the telescopic plate 29 are locked and fixed through a fastening bolt 30. A plurality of groups of tooth grooves 28 for cooperating with the pressing roller 10 are arranged at the lower end of the telescopic plate 29. By providing the tooth grooves 28, when the pressing roller 10 rotates, the tooth-shaped structure on its surface can pass through the tooth grooves 28. At the same time, the inclined telescopic plate 29 can clean the soil on the surface of the pressing roller 10, so that the pressing roller 10 maintains a good use effect.

[0046] A partition is provided inside the seeding hopper 6, and feeding grooves 15 are arranged on both sides of the partition inside the seeding hopper 6. Linkage members 4 are fixedly installed on both sides of the outer housing 1. The linkage member 4 is of a housing structure and is mainly used to protect the tooth chain structure of the equipment. In the case of good soil moisture, a fertilizer discharging leg is arranged in front of and below the seed discharging leg 13, and a fertilizer applicator is added to utilize the two feeding grooves 15 to realize the common discharge of fertilizer and seeds, so that the fertilizer is located below the seeds, which can make full use of chemical fertilizers and avoid the situation of burning seedlings.

[0047] During use, the traditional equipment adopts a single-axis structure design, which causes soil and weeds to accumulate during sowing, and soil adheres to the seed discharging leg 13 and the pressing roller 10, resulting in unsuccessful sowing.

[0048] Therefore, by providing the second cutter shaft 12, the third cutter shaft 2 and the inclined surface clamping plate 16, when the three-axis rotary tillage fertilizing seeder is used, in cooperation with the use of the first cutter shaft 14, it has a three-axis rotary tillage structure, improves the use effect of the fertilizing seeder, avoids the adhesion of soil and weeds to the seed discharging leg 13 and the pressing roller 10, and has a synchronous cleaning structure.

[0049] During operation, the user docks the connecting frame 7 with the tractor and places the seeds inside the seeding hopper 6. When the fertilizer seeder is moving under the drag of the tractor, the L-shaped blade 5 of the first cutter shaft 14 contacts the soil, and the L-shaped blade 5 is used to perform rotary tillage on the soil. In addition to the function of rotary tillage, the L-shaped blade 5 can also crush the remaining straw and spread it deep under the soil layer, converting the straw into fertilizer for use. Secondly, the tooth chain structure is used to make the first cutter shaft 14, the second cutter shaft 12, the pressing roller 10 and the third cutter shaft 2 rotate synchronously. The second cutter shaft 12 drives the short rotary tillage blades 11 to rotate. Since the short rotary tillage blades 11 on the second cutter shaft 12 are placed on both sides of the seed discharging leg 13, when the short rotary tillage blades 11 rotate, they scrape the soil and straw attached to the seed discharging leg 13, avoiding the adhesion of soil and straw to the seed discharging leg 13, reducing the moving resistance of the seed discharging leg 13, and ensuring the smooth progress of seeding. The pressing roller 10 is used to roll and press the soil after seeding to compact the soil. When the pressing roller 10 is continuously used, a large amount of soil will adhere to the surface of the pressing roller 10, affecting its use effect. When the pressing roller 10 rotates, it synchronously drives several groups of scraping blades 3 to rotate. The several groups of scraping blades 3 play the role of scraping the soil on the surface of the pressing roller 10 and loosening the ground surface pressed by the pressing roller 10. At the same time, the telescopic plate 29 can make the tooth-shaped structure on the surface of the pressing roller 10 pass through the tooth grooves 28 during rotation by setting the tooth grooves 28. At the same time, the inclined telescopic plate 29 can clean the soil on the surface of the pressing roller 10, enabling the pressing roller 10 to maintain a good use effect. The use height of the telescopic plate 29 can be adjusted by cooperating with the inclined surface clamping plate 16 using the fastening bolt 30;

[0050] Secondly, the soil crushing rate of traditional equipment is low, there are phenomena such as wheat seedlings being pressed by large soil clods and not emerging, wheat seedlings being hanged due to straw buried in the soil, and soil compaction after the pressing roller 10 of the seeder passes, etc., which will greatly reduce the use effect of the fertilizer seeder and reduce the seed survival rate;

[0051] Therefore, by setting the L-shaped blade 5 and the short rotary tillage blades 11, when the three-axis rotary tillage fertilizer seeder is in use, it has a multiple soil crushing structure, enabling the soil in the planting area to fully complete the soil crushing operation, keeping the soil soft during the planting process, and improving the seeding effect of the fertilizer seeder;

[0052] In use, the first cutter shaft 14 drives the seven-character cutter 5 to rotate. One end of the seven-character cutter 5 is designed with an arc-shaped bending structure, so that when the seven-character cutter 5 rotates, it can not only break the soil, but also cut the straw in the soil, thus completing the preliminary soil loosening operation. This step can break the lumpy soil. Secondly, due to the design of the tooth chain structure, the second cutter shaft 12 and the third cutter shaft 2 are synchronously driven. The second cutter shaft 12 drives the short rotary tillage cutter 11 to rotate. When the short rotary tillage cutter 11 contacts the soil, the soil in the seeding layer is rotary tilled for the second time, and the soil fragmentation rate is further improved, providing a better environment for the seeds and ensuring the emergence rate. After the pressing roller 10 rolls the sown soil, several groups of scraping knives 3 can loosen the surface of the soil pressed by the pressing roller 10;

[0053] At the same time, during the use of traditional equipment, its seeding structure is prone to blockage during the falling process of seeds, making the seeds unable to be discharged normally. It does not have a synchronous feeding structure, reducing the use effect of the fertilizer seeding machine;

[0054] Therefore, by setting up the lifting hopper 25, when this three-axis rotary tillage fertilizer seeding machine is in use, the use of the seed discharging leg 13 is optimized to make it have a synchronous feeding structure, avoiding the blockage of seeds inside the seed discharging leg 13 and improving its seeding stability;

[0055] During operation, the seeds are put into the feeder 27 through the feeding pipe 20. To avoid the blockage of seeds during the feeding process, by setting the seed discharging leg 13 in a movable state, the seed discharging leg 13 moves up and down when it contacts the soil, and the seed discharging leg 13 drives the lifting hopper 25, so that the lifting hopper 25 drives the seeds in the feeder 27 to move up and down, thus avoiding the blockage of seeds inside the feeder 27. Secondly, the setting of the soil breaker 24 can reduce the resistance when the seed discharging leg 13 moves, and at the same time, the protective pad 23 plays a protective role at the bottom of the seed discharging leg 13, while the setting of the limit ring 26 can limit the lifting range of the seed discharging leg 13, making it adaptively adjusted according to the soil conditions.

[0056] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
