Description

Technical Field

[0001] This utility model relates to the field of seeding equipment technology, specifically to a seed guide tube for a double-seedling belt seeder. Background Technology

[0002] The double-seedling belt seeder is a highly efficient agricultural machine capable of simultaneously sowing two different crops, widely used in modern agricultural production. Its working principle involves using a double-seedling belt sowing device to achieve synchronous sowing of two crops, thereby improving sowing efficiency and land utilization. In the double-seedling belt seeder, the seed guide tube is a crucial component, typically connected directly to the output end of the seed metering device. The seed metering device, in turn, is connected to the seed box, used to transfer seeds from the seed box to the individual seeding units, ultimately completing the sowing process. The design and performance of the seed guide tube directly affect the accuracy and efficiency of sowing.

[0003] In existing technologies, the seed guide tube of a double-seedling belt seeder is generally fixedly connected to the bottom of the seed metering device by bolts or screws, or integrally formed with the bottom of the seed metering device's outer shell. This fixing method ensures the stability of the connection between the seed guide tube and the seed metering device to a certain extent.

[0004] However, since different crops have different requirements for sowing depth, the existing seed guide tube fixing method cannot be height adjusted according to actual needs, making it difficult to accurately control the sowing depth and affecting the sowing quality. Furthermore, the limitation of the fixing method makes the replacement or installation of the seed guide tube cumbersome, further reducing sowing efficiency. Therefore, this utility model proposes a single seed guide tube for a double-seedling seeder to solve the above problems. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a seed guide tube for a double-seedling seeder, comprising: a seed guide tube 1, which is curved to allow seeds to fall more smoothly; a seed guide disc 2 is fixedly connected to the top of the seed guide tube 1, the seed guide disc 2 having a large opening area to prevent seeds from flying out of the seed guide tube 1 after falling, and also guiding the seeds; a through hole starting from the center of the seed guide disc 2 communicates with the top of the seed guide tube 1; a quick-release component is connected to one side of the seed guide disc 2 for easy disassembly, which facilitates the disassembly of the seed guide disc 2, thereby facilitating the disassembly of the seed guide tube 1 and subsequent maintenance of the seed guide tube 1; the quick-release component is installed at one end of a lifting plate 3, and an adjustment component is installed at the other end of the lifting plate 3 for adjusting the vertical movement of the lifting plate 3; the height of the seed guide disc 2 is adjusted by adjusting the height of the lifting plate 3 through the adjustment component. The height of the seed guide tube 1 can be adjusted to adapt to the sowing depth requirements of different crops. A seed metering device 4 is provided on the upper side of the seed guide tray 2. The seed metering device 4 is existing technology and will not be described in detail here. One side of the seed metering device 4 is connected to the drive component of the seeder. The upper side of the seed metering device 4 is welded and fixed to the seed box 6 through the connecting frame 5, thereby fixing the seed box 6 through the connecting frame 5. One side of the seed metering device 4 is connected to the bottom output end of the screw conveyor 7. The screw conveyor 7 is existing technology and will not be described in detail here. The top input end of the screw conveyor 7 is connected to the seed box 6. The lower surface of the seed box 6 is fixedly connected to the screw conveyor 7. The screw conveyor 7 is electrically connected to the control equipment of the seeder. A mounting frame 8 is welded and fixed to one side wall of the seed box 6. The setting of the mounting frame 8 facilitates the fixing of the seed box 6, thereby installing it on the double seedling belt seeder, and then fixing the other components through the seed box 6.

[0023] The seed box 6 is fixed to the double-seedling belt seeder via the mounting frame 8, thus providing support for the other components. An appropriate amount of seeds is filled into the seed box 6. By starting the screw conveyor 7, the rotating screw blades feed the seeds from the seed box 6 into the seed metering device 4. The seed metering device 4 controls the separation and quantitative release of seeds, ensuring uniform and efficient sowing. The seeds falling through the seed metering device 4 fall into the seed guide tray 2. Under the limiting action of the seed guide tray 2, the seeds are guided into the seed guide tube 1, and then through the seed guide tube 1, the seeds are guided into the prepared trench. When the seed guide tube 1 needs to be disassembled and reassembled, it can be quickly installed and disassembled using the easy-to-disassemble component, facilitating maintenance. Simultaneously, when the height of the seed guide tube 1 needs to be adjusted, the height of the lifting plate 3 is adjusted using the adjustment component, which in turn moves the seed guide tube 1 up and down, thus adjusting the height of the seed guide tube 1 to adapt to the sowing depth required for different crops.

[0024] The easy-to-disassemble component includes a limiting block 9, with a limiting groove 10 at its bottom. A limiting strip 11 is slidably connected to the limiting groove 10, limiting the limiting block 9. The limiting strip 11 is fixedly connected to the upper surface of one end of the lifting plate 3. One side of the upper surface of the limiting block 9 is welded and fixed to the seed guide plate 2, thereby driving the seed guide plate 2 to move synchronously through the limiting block 9. The seed guide plate 2 then drives the seed guide tube 1 to move synchronously. A limiting hole 12 is provided at the top of the limiting block 9, with one end of a limiting rod 13 slidably inserted into the limiting hole 12, thereby limiting the movement of the limiting rod. Rod 13 limits the limiting hole 12, thereby limiting the limiting block 9 to limit the seed guide plate 2. The other end of the limiting rod 13 is slidably sleeved on the top of the fixed frame 14 and is fixedly connected to the top of the fixed frame 14 by a spring 15. The fixed frame 14 limits the limiting rod 13. One side of the bottom of the fixed frame 14 is fixedly connected to the lifting plate 3. A pressure rod 16 is slidably sleeved in the middle of the fixed frame 14. The pressure rod 16 is arranged perpendicular to the limiting rod 13. The pressure rod 16 is slidably connected to the slider 18 fixedly connected in the middle of the limiting rod 13 through the sliding groove 17 opened in the middle.

[0025] In the initial state, the limiting rod 13 is inserted into the limiting hole 12. When it is necessary to disassemble the seed guide plate 2, the pressure rod 16 is pressed towards the connecting frame 5, causing the pressure rod 16 to move laterally under the limitation of the fixed frame 14. The pressure rod 16 slides between the sliding groove 17 on it and the slider 18 fixedly connected to the limiting rod 13. The limiting compression between the sliding groove 17 and the slider 18 causes the limiting rod 13 to move upward under the limitation of the fixed frame 14. The limiting rod 13 compresses the spring 15, thereby limiting the movement. The bottom of the rod 13 slides out of the limiting hole 12 on the limiting block 9. Then, through the adjustment component, the seed guide plate 2 is adjusted to be lower than the bottom of the seed metering device 4. Then, through the cooperation of the limiting groove 10 and the limiting strip 11, the limiting block 9 is removed, thereby indirectly removing the seed guide tube 1 for easy maintenance of the seed guide tube 1. When it is necessary to install the seed guide tube 1, simply slide the limiting block 9 onto the upper surface of one end of the lifting plate 3, and then, through the reverse elastic force of the spring 15, the limiting rod 13 can be inserted into the limiting hole 12, thereby indirectly fixing and limiting the seed guide tube 1.

[0026] The adjustment assembly includes a set of support plates 19. The tops of the two support plates 19 are fixedly connected to the lower surface of the seed box 6. A threaded rod 20 is rotatably sleeved between the bottoms of the two support plates 19. The support plates 19 limit the threaded rod 20. An adjustment block 21 is symmetrically threaded onto the threaded rod 20. The threaded rod 20 has two threads with opposite directions. An adjustment plate 22 is provided on the lower side of the threaded rod 20. The lower surface of the adjustment plate 22 is fixedly connected to the lifting plate 3. A connecting seat 23 is fixedly connected to the upper surface of the adjustment plate 22. The connecting seat 23 is rotatably connected to one end of the connecting rod 24 through a connecting pin. The other end of the connecting rod 24 is rotatably connected to the adjustment block 21 through a limiting pin.

[0027] When the height of the seed guide tube 1 needs to be adjusted, the handwheel fixedly installed at one end of the threaded rod 20 is turned to make the handwheel drive the threaded rod 20 to rotate in both directions. Under the action of the rotation of the threaded rod 20, the adjusting blocks 21 symmetrically threaded on it are driven. When the two adjusting blocks 21 move in opposite directions, the adjusting plate 22 drives the lifting plate 3 to rise through the rotational cooperation between the limiting pin, connecting rod 24, connecting seat 23 and connecting pin. When the two adjusting blocks 21 move towards each other, the adjusting plate 22 drives the lifting plate 3 to move downward, and then indirectly drives the seed guide tube 1 to rise and fall through the connection of the limiting block 9, so as to adapt to the requirements of different crops for sowing depth.
