Description

Technical Field

[0001] This utility model relates to the field of agricultural seeding equipment technology, and in particular to a seeding device suitable for seeds of different particle sizes. Background Technology

[0002] In large farms, it can easily handle the large-diameter sowing of seeds such as kenaf, corn, and soybeans, as well as the large-scale sowing of small seeds such as jute, flax, and vegetables, ensuring uniform sowing in each row and increasing overall yield. In small family yards, it can be used to precisely sow flower and herb seeds to meet personalized planting needs and help growers increase their income. It has great practical value in various agricultural planting scenarios.

[0003] In the existing technology, some seeding devices typically consist of a seed storage bin, a seed metering mechanism, a drive device, and a control system, which provide power to the seeding device so that it can move in the field and drive the seed metering mechanism to achieve efficient and precise seeding operations, improve seeding quality and efficiency, and meet the diversified planting needs of modern agriculture.

[0004] However, in actual use, it cannot adapt to the sowing of seeds of different sizes. The limitations of the seed metering system make it difficult to adjust flexibly. Large-diameter seeds are prone to getting stuck in narrow channels, affecting the continuity of sowing. Small-diameter seeds are prone to over-sowing or missed sowing due to excessive spacing, resulting in uneven sowing density. In order to address the above problems, a sowing device suitable for seeds of different sizes is proposed. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 , Figure 4 This utility model provides an embodiment of a sowing device suitable for seeds of different particle sizes, including a support plate 1. The support plate 1 is rectangular and flat, providing a stable support platform for the entire sowing device. Multiple connecting blocks 2 are fixedly connected to the outside of the support plate 1. Telescopic rods 3 are fixedly connected to the outside of the connecting blocks 2. The telescopic rods 3 are composed of multiple nested rod sections and can be extended and retracted according to actual needs. A spring 4 is sleeved on the outside of the telescopic rods 3. The spring 4 is spiral-shaped. When the telescopic rods 3 are extended and retracted by external force, the spring 4 can play a role in buffering and resetting. A connecting plate 5 is fixedly connected to the outside of the telescopic rods 3. A storage bin 6 is fixedly connected to the outside of the connecting plate 5. The storage bin 6 is funnel-shaped, wider at the top and narrower at the bottom, and is used to store a large number of seeds.

[0034] The storage bin 6 is externally fixedly connected to a conveying bin 7. One end of the conveying bin 7 is connected to the storage bin 6, and the other end is used to transport the seeds to the sowing position. The conveying bin 7 is internally fixedly connected to a disassembly mechanism, and the storage bin 6 is internally fixedly connected to an anti-blocking mechanism. The disassembly mechanism includes a follower plate 8, which is rectangular in shape and has a groove inside that is adapted to the installation of a screen 9, so that the screen 9 can be detachably connected to the inside of the follower plate 8. The screen 9 is detachably connected inside the follower plate 8. The screen 9 has a mesh structure, and its mesh size can be changed according to the different seed particle sizes to screen seeds of different particle sizes. The follower plate 8 is externally fixedly connected to a connecting block 10, and the connecting block 10 is externally fixedly connected to a sliding plate 11.

[0035] A connecting rod 12 is fixedly connected to the outside of the sliding plate 11, and an elastic component is fixedly connected to the outside of the connecting rod 12. A limit component is fixedly connected to the inside of the sliding plate 11. The follower plate 8 is slidably connected to the inside of the conveying chamber 7. The elastic component includes a second spring 13, a fixing rod 14 is fixedly connected to the outside of the second spring 13, and a support block 15 is fixedly connected to the outside of the fixing rod 14. The support block 15 is used to fix the position of the second spring 13 so that it remains stable during operation. The second spring 13 is fixedly connected to the outside of the connecting rod 12. The limit component includes a limit block 16, a connecting plate 17 is slidably connected to the outside of the limit block 16, a follower rod 18 is fixedly connected to the outside of the connecting plate 17, and the limit block 16 is fixedly connected to the outside of the sliding plate 11.

[0036] Reference Figure 2 , Figure 3 , Figure 4 The anti-blocking mechanism includes a motor 19. When the motor 19 is turned on, its drive end will drive the active rod 20 to rotate clockwise. The drive end of the motor 19 is fixedly connected to the active rod 20. The active rod 20 is fixedly connected to the outside of the protective shell 21. The motor 19 is fixedly connected to the outside of the connecting plate 5. The active rod 20 is fixedly connected to the outside of the active bevel gear 22. The active bevel gear 22 is shaped like a truncated cone, and its teeth are evenly distributed on the conical surface. The active bevel gear 22 is rotatably connected to the outside of the active bevel gear 22. The driven bevel gear 23 is also shaped like a truncated cone, and its teeth mesh tightly with the teeth of the active bevel gear 22 to realize the transmission of power. The driven bevel gear 23 is rotatably connected to the inside of the protective shell 21.

[0037] A driven rod 24 is fixedly connected to the external of the driven bevel gear 23. The driven rod 24 is cylindrical, coaxial with the driven bevel gear 23, and firmly connected to the driven bevel gear 23. Multiple anti-blocking plates 25 are fixedly connected to the external of the driven rod 24. The anti-blocking plates 25 will rotate in a circular motion. Using the centrifugal force and scraping action generated by their rotation, they can clean up materials that may cause blockage inside the conveying chamber 7 and prevent material accumulation from causing blockage. One end of the second spring 13 is fixedly connected to the external of the connecting rod 12, and the other end of the second spring 13 is fixedly connected to the external of the fixed rod 14. The external of the sliding plate 11 is slidably connected to the external of the support block 15, and the external of the support block 15 is fixedly connected to the internal of the conveying chamber 7.

[0038] Working principle: Through the support plate 1 and the telescopic rod 3 connected by the connecting block 2, and with the spring 4, the height can be adjusted according to actual needs. A large number of seeds are stored in the funnel-shaped storage bin 6, and then conveyed to the sowing position through the conveying bin 7 connected to the storage bin 6. The screen 9 screens the seeds, causing the follower plate 8 to slide in the conveying bin 7, driving the connecting block 10 and the sliding plate 11 to move. Then, the sliding plate 11 causes the spring 13 to extend and retract through the connecting rod 12, causing the sliding plate 11 to drive the limiting block 16 to move, so that the follower rod 18 limits the sliding plate 11, assisting the follower plate 8 to slide smoothly, thereby completing the screening and conveying of seeds of different particle sizes.

[0039] After the motor 19 is powered on and started, the drive rod 20 rotates clockwise due to the sturdy connection structure. This causes the drive rod 20 to drive the drive bevel gear 22 to rotate synchronously. The conical teeth of the drive bevel gear 22 mesh tightly with the teeth of the driven bevel gear 23, allowing the driven bevel gear 23 to rotate stably inside the protective shell 21. When the driven bevel gear 23 rotates, the driven rod 24, which is coaxial with and firmly connected to it, is also driven to rotate. This causes the anti-blocking plate 25 to make a circular motion around the driven rod 24, continuously impacting the material accumulated inside the conveying chamber 7, making it difficult for the material to accumulate and cause blockage.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
