Therefore, when the seed enters the duckbill tube through the transparent tube, the duckbill tube moves down to its lowest point. At this time, the pointed part at the bottom of the duckbill tube is inserted into the soil, allowing the seed to be accurately sown into the soil under the guidance of the duckbill tube. Through the angular difference when the first ball head shaft and the second ball head shaft rotate synchronously, the seed is pushed into the soil without the duckbill tube damaging the seed. At the same time, only one set of power output mechanism is needed to drive the roller, duckbill tube and seed conveying mechanism to run simultaneously, improving the seed sowing accuracy, reducing the labor intensity of workers and improving sowing efficiency.
[0019] 2. When the engine is running, the first drive shaft is driven to rotate via the transmission belt. When the first drive shaft rotates, the second drive shaft and rollers are driven to rotate simultaneously via the first and second gearboxes at both ends, thereby moving the seeder forward as a whole while performing the sowing operation.
[0020] 3. The height of the connecting block can be adjusted by rotating the threaded rod, thereby adjusting the overall height of the second drive shaft, which in turn allows for fine-tuning of the depth of the duckbill tube inserted into the soil. This improves the overall applicability of the seeder and enables it to accurately deliver seeds to the standard depth. After adjustment, the threaded rod can be fixed with a nut.

Detailed Implementation
[0029] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0030] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.
[0031] Example 1
[0032] A type of seeder, such as Figure 1-7 As shown, the device includes a mounting frame 1. A support frame 11 is fixed to the top outer wall of the mounting frame 1. A seed conveying device 9 and a set of connecting frames 14 are fixed to the top outer wall of the support frame 11. A connecting block 19 is slidably connected to the inner wall of the connecting frame 14. A second drive shaft 21 is rotatably connected to the inner wall of the connecting block 19 through a bearing. A power output mechanism is provided on the top outer wall of the mounting frame 1. The second drive shaft 21 is connected to the power output mechanism through a transmission chain. A first connecting handle 18 is fixed to both ends of the second drive shaft 21. A first ball head shaft 28 is fixed to one side outer wall of the first connecting handle 18. A first push rod 16 is universally connected to the outer wall of the first ball head shaft 28. A first movable frame 26 is rotatably connected to the outer wall of the first push rod 16. The first movable frame 26 is slidably connected to one side outer wall of the support frame 11. Multiple duckbill tubes 2 are fixed to one side outer wall of the first movable frame 26.
[0033] One end of the first ball head shaft 28 is fixed with a second connecting handle 17. A second ball head shaft 29 is fixed to one side of the outer wall of the second connecting handle 17. A second push rod 15 is universally connected to the outer wall of the second ball head shaft 29. A second movable frame 23 is rotatably connected to the bottom outer wall of the second push rod 15. A plurality of spring pieces 32 are fixed to the bottom outer wall of the second movable frame 23. The spring pieces 32 are inserted into the inner wall of the duckbill tube 2. The second movable frame 23 is slidably connected to one side of the outer wall of the first movable frame 26. The top end of the duckbill tube 2 is connected to the feeding pipe on the seed conveying device 9 through a transparent flexible tube.
[0034] The second drive shaft 21 has a second drive gear 13 fixed at one end, and the second drive gear 13 is connected to the seed conveying device 9 in a transmission connection.
[0035] In this utility model, the seed conveying device 9 is the seed conveying device described in patent number CN2025100459434.
[0036] A set of rollers 10 are rotatably connected to the inner wall of the mounting frame 1. One end of each roller 10 is fixed with a first transmission gear 12. The rollers 10 are connected to the power output mechanism via a transmission chain. The two first transmission gears 12 are connected to each other via a transmission chain.
[0037] After the power output mechanism is started, it will drive the second drive shaft 21 and the roller 10 to rotate through the transmission chain. When the roller 10 rotates, it will drive the seeder to move forward at a uniform speed. When the second drive shaft 21 rotates, it will first drive the seed conveying device 9 to run through the second transmission gear 13 on one side, thereby conveying the seeds in the seed bin out one by one through the feeding pipe and into the corresponding duckbill tube 2 through the transparent hose.
[0038] When the second drive shaft 21 rotates, it simultaneously drives the first connecting handle 18 at one end to rotate. When the first connecting handle 18 rotates, it pushes the first movable frame 26 to move up and down under the guidance of the inner wall of the support frame 11 via the first push rod 16 on the outer wall. At the same time, when the first ball head shaft 28 rotates with the first connecting handle 18, it drives the second connecting handle 17, which is fixed at one end, to rotate. When the second connecting handle 17 rotates, it drives the second push rod 15 to rotate up and down via the second ball head shaft 29 on the outer wall. This pushes the second movable frame 23 to slide up and down on one side of the first movable frame 26 via the second push rod 15, thus allowing the duckbill tube 2 on one side of the first movable frame 26 to move up and down cyclically. Since the second drive shaft 21 is connected to the seed conveying device 9 via the second drive gear 13, the frequency at which the seed conveying device 9 conveys seeds outward can match the frequency at which the duckbill tube 2 moves up and down. Therefore, when the seed enters the duckbill tube 2 through the transparent tube, the duckbill tube 2 moves downward to its lowest point. At this time, the pointed part at the bottom of the duckbill tube 2 is inserted into the soil. Through the angular difference when the first ball head shaft 28 and the second ball head shaft 29 rotate synchronously, the seed is pushed into the soil without being crushed by the duckbill tube 2. At the same time, the second movable frame 23 will also drive the bottom spring piece 32 to move downward, thereby opening the duckbill opening at the bottom of the duckbill tube 2, allowing the seed to be smoothly discharged into the soil through the bottom opening of the duckbill tube 2. Thus, the seed can be accurately sown into the soil under the guidance of the duckbill tube 2. At the same time, only one power output mechanism is needed to drive the roller 10, the duckbill tube 2 and the seed conveying mechanism to operate simultaneously, improving the seed sowing accuracy, reducing the labor intensity of the workers and improving the sowing efficiency.
[0039] like Figure 6-7 As shown, multiple seed conveying devices 9 can be combined and installed on one side of the support frame 11 according to actual needs, thereby improving the applicability of the seeder.
[0040] like Figure 1-3 As shown, the power output mechanism includes an engine 7, a mounting plate 5, a first drive shaft 6, a first gearbox 4, and a second gearbox 8. The engine 7 is fixed to the top outer wall of the mounting frame 1, and a set of mounting plates 5 are fixed to the top outer wall of the mounting frame 1. The first gearbox 4 and the second gearbox 8 are respectively fixed to the top outer wall of the mounting plate 5. The two ends of the first drive shaft 6 are respectively connected to the input ends of the second gearbox 8 and the first gearbox 4. The first drive shaft 6 is connected to the output shaft of the engine 7 via a drive belt. The output shaft of the second gearbox 8 is connected to the roller 10 via a drive chain. The output shaft of the first gearbox 4 is connected to the second drive shaft 21 via a drive chain.
[0041] When the engine 7 is running, it drives the first drive shaft 6 to rotate via the transmission belt. When the first drive shaft 6 rotates, it can drive the second drive shaft 21 and the roller 10 to rotate simultaneously via the first gearbox 4 and the second gearbox 8 at both ends, thereby driving the seeder to move forward as a whole while performing the sowing operation.
[0042] like Figure 4 As shown, a tensioning wheel 27 is rotatably connected to one side of the outer wall of the support frame 11; the tensioning wheel 27 can tension the transmission chain connecting the second transmission shaft 21 and the output shaft of the first gearbox 4.
[0043] like Figure 4 As shown, a set of pulleys 25 are rotatably connected to one side of the outer wall of the second movable frame 23. The pulleys 25 are rolled on one side of the outer wall of the guide plate 24. When the second movable frame 23 moves up and down on one side of the guide plate 24, it can drive the pulleys 25 to roll up and down on both sides of the guide plate 24, thereby guiding the second movable frame 23 when it moves up and down and improving the stability of the second movable frame 23 when it drives multiple duckbill tubes 2 to move up and down.
[0044] like Figure 4 As shown, the inner wall of the connecting frame 14 is connected to a threaded rod 20 by a thread. The bottom outer wall of the threaded rod 20 is rotatably connected to the top outer wall of the connecting block 19. The overall height of the connecting block 19 can be adjusted by rotating the threaded rod 20, thereby adjusting the overall height of the second drive shaft 21, and thus fine-tuning the depth of the duckbill tube 2 inserted into the soil, improving the overall applicability of the seeder. After the adjustment is completed, the threaded rod 20 can be fixed with a nut.
[0045] like Figure 4 As shown, a support bearing 22 is rotatably connected to the outer wall of the second drive shaft 21. A telescopic rod 33 is fixed to the bottom outer wall of the support bearing 22. The telescopic end of the telescopic rod 33 is fixed to the top outer wall of the first movable frame 26. When the first movable frame 26 moves up and down under the push of the first push rod 16, it can push the telescopic end of the bottom of the telescopic rod 33 to extend and retract up and down, thereby guiding the first movable frame 26 when it moves up and down through the telescopic rod 33.
[0046] like Figure 1-2 As shown, a set of U-shaped tubes 3 are fixed on the top outer wall of the mounting frame 1, and a generator 31 is fixed on the top outer wall of the mounting frame 1. The input end of the generator 31 is connected to the output shaft of the engine 7. The seeder can be easily lifted and turned and moved through the U-shaped tubes 3, and plays a role in carrying and guiding during operation. The generator 31 can provide power to drive the vacuum pump on the seed conveying device 9.
[0047] like Figure 5The support frame 11 has a set of springs 30 fixed on one side of its outer wall. One end of the springs 30 is fixedly connected to one side of the outer wall of the guide plate 24. The springs 30 can limit the movement of the first movable frame 26 and the guide plate 24 as a whole when they swing up and down by their own elasticity. At the same time, the springs 30 can pull the first movable frame 26 and the guide plate 24 as a whole to swing back by their own elasticity, thereby improving the stability of the first movable frame 26 and the guide plate 24 as a whole when they swing up and down under the push of the first push rod 16.
[0048] Working principle: After the power output mechanism is started, it will drive the second transmission shaft 21 and the roller 10 to rotate through the transmission chain. When the roller 10 rotates, it will drive the seeder to move forward at a uniform speed. When the second transmission shaft 21 rotates, it will first drive the seed conveying device 9 through the second transmission gear 13 on one side, thereby conveying the seeds in the seed bin out one by one through the feeding pipe and into the corresponding duckbill tube 2 through the transparent hose.
[0049] When the second drive shaft 21 rotates, it will simultaneously drive the first connecting handle 18 at one end to rotate. When the first connecting handle 18 rotates, it will push the first movable frame 26 to move up and down under the guidance of the inner wall of the support frame 11 through the first push rod 16 on the outer wall. At the same time, when the first ball head shaft 28 rotates with the first connecting handle 18, it will drive the second connecting handle 17, which is fixed at one end, to rotate. When the second connecting handle 17 rotates, it will drive the second push rod 15 to rotate up and down through the second ball head shaft 29 on the outer wall. Thus, the second movable frame 23 will be pushed up and down on one side of the first movable frame 26 through the second push rod 15, so that the duckbill tube 2 on one side of the first movable frame 26 will move up and down in a cycle.
[0050] When the seed enters the duckbill tube 2 through the transparent tube, the duckbill tube 2 moves downwards to its lowest point. At this time, the pointed part at the bottom of the duckbill tube 2 is inserted into the soil. Through the angular difference when the first ball head shaft 28 and the second ball head shaft 29 rotate synchronously, the seed is pushed into the soil without being crushed by the duckbill tube 2. At the same time, the second movable frame 23 will also drive the bottom spring piece 32 to move downwards, thereby opening the duckbill opening at the bottom of the duckbill tube 2, allowing the seed to be smoothly discharged into the soil through the bottom opening of the duckbill tube 2. Thus, the seed can be accurately sown into the soil under the guidance of the duckbill tube 2.
[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
