Technical Field
[0001] This utility model relates to the field of agricultural equipment technology, specifically to a single-unit integrated seed guide groove for a seeder. Background Technology
[0002] A seeder is a mechanical device used for agricultural sowing operations. Its main function is to evenly sow seeds into the soil according to predetermined row spacing, plant spacing, and depth, thereby improving sowing efficiency and work quality. During the operation of the seeder, seeds are released into the seed guide trough through the seed metering device, and then fall into the soil along the guide trough. As a key component of the seeder, the seed guide trough directly determines the path and stability of the seed's fall, and has a significant impact on sowing accuracy.
[0003] In current technology, the seed guide trough of a seeder is usually located below the seed metering device to receive and guide the seeds as they fall. The connection between the seed guide trough and the seed metering device is mostly secured with small bolts or screws, which to a certain extent ensures the stability and reliability of the seed guide trough.
[0004] However, in actual use, the seed guide trough plate is subjected to high-speed impact and friction from seeds, as well as abrasion from soil particles over a long period. Its surface coating is prone to peeling off, and the trough shape gradually deforms, which seriously affects the seed guiding accuracy and the lifespan of the seeder. Furthermore, some seeds (such as crop seeds with sharp edges or hard shells) may have a cutting effect on the seed guide trough plate, accelerating its material fatigue. Simultaneously, dust, moisture, and other media in the working environment can also accelerate corrosion of the seed guide trough plate surface. When the seed guide trough plate needs replacement, maintenance personnel usually need to disassemble each small bolt or screw to remove it from the seed metering device, and then tighten each bolt or screw individually during reinstallation. This operation is not only time-consuming and labor-intensive, but also extremely inconvenient for maintenance and replacement within the confined space of the seeder, reducing equipment maintenance efficiency and operational continuity. Therefore, this utility model proposes a single-unit integrated seed guide trough for the 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 4This utility model provides a technical solution: a single-unit integrated seed guide trough for a seeder, comprising: a seed guide trough plate 1, the inside of which is arc-shaped to facilitate the smooth falling of seeds; the top of the seed guide trough plate 1 is inserted into the bottom of a seed metering device 2, which is existing technology. The working principle of the seed metering device 2 is to transport seeds from a storage device to the sowing position, and according to the set sowing density and row spacing, use mechanical, pneumatic, or other driving methods to evenly and accurately place the seeds on the soil surface or at a specific depth, so as to ensure... To ensure seed distribution and implantation meet planting requirements, limiting sleeves 3 are fixedly connected to both sides of the seed guide plate 1. A first limiting component is provided on one side of the limiting sleeve 3. The first limiting component limits the limiting sleeve 3, thus initially fixing the seed guide plate 1 to the bottom of the seed metering device 2. A second limiting component is provided at one end of the mounting plate 9 near the side of the seed metering device 2. The mounting plate 9 facilitates the fixing between the seed metering device 2 and the seed box of the seeder. The second limiting component further limits the seed guide plate 1, thereby improving its... For stability during use, the first limiting component includes a limiting rod 4. One end of the limiting rod 4 is slidably inserted into the limiting sleeve 3, and the other end of the limiting rod 4 is fixedly connected to the support frame 5 with a first spring 6. The middle part of the limiting rod 4 is slidably connected to one end of the inclined rod 8 through an inclined hole 7. The limiting rod 4 slides with the inclined rod 8 due to the compression between the inclined rod 8 and the inclined hole 7. The other end of the inclined rod 8 is provided with a pushing component, which drives the inclined rod 8 on the support frame 5 towards the limiting rod 4. The sliding limit rod 4 and the inclined rod 8 are both slidably installed on the support frame 5. The support frame 5 supports and limits the limit rod 4 and the inclined rod 8. The support frame 5 is fixedly installed at the bottom of the seed metering device 2. The second limiting component includes a connecting plate 10. One end of the connecting plate 10 is fixedly connected to the seed guide plate 1. The other end of the connecting plate 10 is slidably inserted with a rod 11. One end of the rod 11 is slidably inserted with the mounting plate 9. The other end of the rod 11 is fixedly connected to the limiting plate 12 through the second spring 13. The limiting plate 12 is fixedly installed on the mounting plate 9.
[0023] The support frame 5 is fixedly connected to the bottom of the seed metering device 2 via an L-shaped plate 14, thereby fixing the support frame 5. The bottom of the L-shaped plate 14 is fixedly connected to a limiting seat 15. The pushing assembly includes a handwheel 16, which is fixedly connected to one end of an adjusting rod 17. The adjusting rod 17 can be rotated by turning the handwheel 16. The other end of the adjusting rod 17 is rotatably sleeved in the end of the inclined rod 8 away from the inclined hole 7. The middle part of the adjusting rod 17 is sleeved in the limiting seat 15 and is threadedly connected to the limiting seat 15. Through the threaded connection between the adjusting rod 17 and the limiting seat 15, the adjusting rod 17 can move along its axis. A limiting frame 18 is fixedly installed on the support frame 5. The limiting frame 18 is slidably connected to the inclined rod 8. The limiting frame 18 is U-shaped, thereby limiting the inclined rod 8 on the support frame 5.
[0024] The connecting plate 10 and the limiting plate 12 are symmetrically arranged about the center plane of the mounting plate 9. The mounting plate 9 has a hole 19 on its side wall that matches the plug rod 11. By plugging the plug rod 11 into the hole 19, the connecting plate 10 can be easily limited to one side of the limiting plate 12. The end of the plug rod 11 away from the hole 19 is fixedly connected to the U-shaped rod 20. The plug rod 11 is slidably connected to the limiting plate 12. The U-shaped rod 20 makes it easy to pull the two plug rods 11 at the same time.
[0025] In actual use, the seed metering device 2 is fixed to the seed box by the mounting plate 9. When it is necessary to install the seed guide plate 1, first pull the U-shaped rod 20 outward to make the U-shaped rod 20 drive the insertion rod 11 to move synchronously. The second spring 13 is stretched, and the insertion rod 11 slides out of the insertion hole 19 under the limit of the limiting plate 12. At this time, the seed guide plate 1 is slid into the seed metering device 2 from the bottom upward, so that the top of the seed guide plate 1 is inserted into the bottom of the seed metering device 2. At the same time, the limiting rod 4 and the limiting sleeve 3 are coaxial. At this point, the U-shaped rod 20 is released. Under the reverse elastic force of the second spring 13, the insertion rod 11 passes through the connecting plate 10 and is inserted into the insertion hole 19 on the mounting plate 9, thereby limiting and fixing one side of the seed guide plate 1. Then, by turning the handwheel 16, the handwheel 16 drives the adjusting rod 17 to rotate. Since the adjusting rod 17 is threadedly connected to the limiting seat 15, the adjusting rod 17 can move upward along its axis. At the same time, one end of the adjusting rod 17 is rotatably inserted into one end of the inclined rod 8. This will push the inclined rod 8 upward under the limitation of the limiting frame 18. The other end of the inclined rod 8 will be squeezed between the inclined hole 7 in the middle of the limiting rod 4 and then slide between the inclined surfaces, so that the limiting rod 4 moves towards the limiting sleeve 3 under the limitation of the support frame 5. At this time, the first spring 6 is compressed until the end of the limiting rod 4 away from the first spring 6 is inserted into the limiting sleeve 3, so as to limit and fix the seed guide plate 1 again. Through the two limiting fixation, the stability of the seed guide plate 1 during use is improved. When the seed guide plate 1 needs to be replaced after a long period of use, the handwheel 16 is turned in the opposite direction to make the adjusting rod 17 move in the opposite direction. Under the action of the reverse elastic force of the first spring 6, the limiting rod 4 slides out of the limiting sleeve 3. At the same time, by pulling the U-shaped rod 20 outward, the U-shaped rod 20 drives the insertion rod 11 to disengage from the insertion hole 19 and the connecting plate 10, thereby releasing the limitation of the seed guide plate 1, so that it can be slid down and pulled out for replacement.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
