Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a seed-supporting device and a seed-seeding device for hill seeders. Background Technology

[0002] In modern agricultural production, the seeder, as a key piece of agricultural machinery, directly determines agricultural production efficiency and operational quality through its design and performance. With the development of large-scale agriculture and the continuous improvement in sowing efficiency requirements, the structural design of seeders faces new challenges and demands. The hill-seeder, as a core component of the seeder, has a significant impact on the seeder's operating speed, sowing accuracy, operational stability, and structural simplicity.

[0003] Existing seeders' hill-seeders struggle to accurately pick and sow irregularly shaped seeds such as corn, nuts, and beans, which have poor uniformity. Therefore, designing a new type of hill-seeder is crucial for achieving precise seeding of these seeds. Utility Model Content

[0004] In view of this, in order to solve the technical problem that existing seeders have poor adaptability to irregularly shaped seeds and seeds of uneven size, this utility model provides a seed-supporting device and a seeder for seeders. By optimizing the seed picking, transporting and dispensing mechanism, it can achieve precision sowing of various types of seeds and improve sowing stability and reliability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: In a first aspect, this utility model provides a seed-supporting device for a hill-planting device, comprising: The seed-collecting ring is fixed to the outer periphery of the seed-collecting assembly. It is a ring with a notch, and the seed-collecting area has a through hole for the seeds to pass through. The inner sealing plate of the locator is fixed to the inside of the locator assembly and covers the inner surface of the locator; The push rod box retaining ring has a circular structure and is concentrically fixed to the inner side of the moving plate assembly; A push rod box is fixed to the push rod box fixing ring; A push rod is located inside the push rod box, and is equipped with rollers and can move along the push rod box; A spring is located inside the push rod box, with its two ends respectively abutting against the inner wall of the push rod box and one end of the push rod; The seed support device, fixed outside the push rod box, is used to hold the seeds to prevent them from falling backward, and works with the push rod to push the seeds to the sowing area; The push rod plate, which is crescent-shaped, is fixed to the lower part of the inner sealing plate of the fixed plate and is located in the seed picking area of ​​the seed chamber. It is used to drive the roller to move the push rod upward to pick up the seed. After the roller is disengaged, the push rod resets and presses the seed through the through hole to put the seed in.

[0006] Secondly, this utility model provides a seeding device, including a fixed disc assembly, a moving disc assembly, a duckbill assembly, and the above-mentioned seed-supporting device for seeding devices.

[0007] Compared with the prior art, this utility model has the following beneficial effects: (1) Precision seed collection is accurate and stable, and adaptable to a variety of seeds. Push rod-compression spring coordinated mechanism: The push rod slides inside the push rod box, and the compression spring always applies pre-pressure to the push rod, pressing the seeds tightly onto the circular track of the seed pick-up guard ring of the fixed plate, preventing them from falling off during transportation, especially for irregularly shaped or unevenly sized seeds, such as corn and beans.

[0008] Seed guide: Supports and assists in seed separation from behind, ensuring each seed moves stably along the track and preventing missed or duplicate seeding. Significantly improves seed collection success rate and is adaptable to most irregularly shaped seeds, solving the problem of poor adaptability to irregularly shaped seeds in traditional hill seeders.

[0009] (2) The seed transport process is reliable and the anti-drop design is significant. The seed-collecting ring is shaped like a notched ring with a smooth surface and a seed-feeding hole. The seeds slide along its circular track under the pressure of the push rod and the push of the seed-support device, and the movement path is fixed.

[0010] The roller works in conjunction with the push rod plate: when the roller contacts the crescent-shaped push rod plate, it moves upward to create a seed-picking gap. After disengaging from the plate, the spring returns to its original position and presses the seed firmly, ensuring no loosening throughout the process. This significantly reduces the seed loss rate during seed transport.

[0011] (3) Instantaneous seeding is highly efficient, and seed delivery is timely with no residue. Spring-powered ejection: When the seed moves to the through-hole position of the seed-collecting guard ring, the spring instantly releases energy, and the push rod "ejects" the seed into the duckbill assembly, significantly shortening the seeding time. The seed-collecting through-holes of the seed-collecting guard ring correspond one-to-one with the duckbill assembly, ensuring that the seed falls vertically into the inner cavity of the duckbill without deviation or residue.

[0012] (4) The planting and seeding are completed simultaneously, improving work efficiency. The duckbill assembly corresponds one-to-one with the push rod: the number of duckbills is installed in the groove of the moving plate as many as the push rods. They enter the soil synchronously with the rotation of the moving plate. The moving nozzle opens automatically due to soil resistance, and the seeds fall directly into the hole.

[0013] Continuous rotation operation: The moving disc assembly rotates around the fixed disc via the seeder shaft, so that the seed picking, seeding and sowing processes are continuous and uninterrupted, without the need for interruption.

[0014] In summary, this utility model organically combines components such as a push rod, push rod box, and compression spring to firmly press the retrieved seeds onto the track to prevent them from falling off. The seeds are then lifted from the seed chamber and moved upwards along the track to the seed outlet. The compression spring releases stored energy, instantly dropping the seeds into the duckbill assembly cavity to complete the seed retrieval process. Under the constraint of the push rod box, the spring's stored energy maintains pressure on the seeds during transport, preventing them from falling off. A seed-supporting device is installed on the back side in the direction of movement to ensure that the seeds pressed by the push rod fall backwards during track movement, coordinating with the push rod to complete the entire seed transport process. The seed-supporting device ensures the reliability and stability of seed retrieval and dispensing, while also providing seed sorting and selection functions throughout the transport process. It is significantly superior to traditional seeders in terms of adaptability to irregularly shaped seeds, operational efficiency, and reliability, providing a highly efficient solution for precision seeding in modern agriculture.

[0019] like Figure 1-5 As shown, this utility model provides a seed-supporting device for a hill-planting machine, comprising: The seed-collecting guard ring 12 is fixed to the outer periphery of the inner surface of the seed-collecting plate assembly 1. It is a notched annular ring with a through hole in its seed-collecting area for the seeds 8 to pass through. Preferably, the through hole is square. The seed-collecting guard ring 12 is preferably fixed to the seed-collecting plate by bolts. It guides the seeds 8 along its annular track and prevents them from falling off. The through hole serves as the seed-collecting channel. Under the action of the push rod and the seed-supporting device 13, the seeds 8 slide along its surface and fall into the through hole, allowing the seeds 8 to enter the inner cavity of the duckbill assembly 7 of the seed planter.

[0020] The inner sealing plate 4 is fixed to the inside of the plate assembly 1, covering the inner surface of the plate. Preferably, it is fixed to the plate in the plate assembly 1 by bolts, and its lower part is used to install the push rod plate 18 described below. It encloses the internal space of the plate, forming the upper boundary of the seed chamber 9; the push rod plate 18 supports the movement of the push rod. Specifically, the push rod plate 18 contacts the rotating roller 15, driving the push rod to move upwards to pick up seeds.

[0021] The push rod box fixing ring 5, with a circular structure, is concentrically fixed to the inner side of the moving plate assembly 3. Preferably, it is fixed to the moving plate of the moving plate assembly 3 by bolts, with equally spaced fixing holes for installing the push rod boxes. The push rod boxes 14 are evenly distributed to ensure consistent seed-taking spacing, causing the push rod boxes to rotate synchronously with the moving plate. With the rotation of the moving plate assembly 3, the push rod boxes sequentially complete seed taking, transporting, and dispensing along a circular trajectory.

[0022] A push rod box 14 is fixed to the push rod box fixing ring 5. A push rod 6 is located inside the push rod box 14, and is equipped with rollers 15, allowing it to move along the push rod box 14. A spring 16 is located inside the push rod box 14, with its two ends respectively abutting against the inner wall of the push rod box 14 and one end of the push rod 6. A seed support 13 is fixed outside the push rod box 14, used to hold the seeds 8 to prevent them from falling backward, and works with the push rod 6 to push the seeds 8 to the sowing area.

[0023] The push rod box 14 is preferably a hollow structure, fixed to the push rod box fixing ring 5, and is used to house the push rod and the spring 16. It is preferably connected to the push rod box fixing ring 5 by bolts, internally constraining the sliding of the push rod and externally fixing the seed support 13. The guide push rod 6 slides up and down, with the spring 16 providing preload and fixing the seed support 13. As the follower disc rotates, the push rod reciprocates under the action of the push rod lever plate 18 and the spring 16, completing the seed picking and dispensing.

[0024] The push rod is located inside the push rod box 14 and can slide up and down. It is equipped with a roller 15 on the outside. One end of the push rod 6 is connected to the spring 16, and the other end is pressed against the inner wall of the push rod box 14. The roller 15 is in contact with the push rod lever plate 18.

[0025] Seed extraction stage: The push rod is driven upward by the push rod lever plate 18 to create a gap for the seed 8 to enter.

[0026] Seed transport stage: Spring 16 applies pressure to press the seeds 8 firmly onto the seed-collecting guard ring 12 of the fixed plate.

[0027] Seeding stage: When passing through the through hole, the spring 16 releases energy to eject the seed 8 into the duckbill assembly 7.

[0028] The push rod rotates with the moving plate. When the roller 15 contacts the push rod lever plate 18, it moves upward. After disengaging, it resets and presses down under the action of the spring 16, completing the "seed picking-seed pressing-seed placement" action.

[0029] The spring 16 is preferably a compression spring, which is compressed within the push rod box 14 to provide continuous downward preload to the push rod 6. It is installed between the push rod box 14 and the push rod 6, with both ends abutting against the inner wall of the push rod box 14 and the push rod 6 respectively, and is in a compressed state. The stored energy provides the preload, causing the push rod to press firmly against the seed 8. During seeding, the energy is released, instantly pushing the seed 8 into the through hole. The roller 15 drives the push rod 6 to compress and store energy; after disengaging from the push rod deflector 18, the pressure is released, driving the push rod downwards to seed.

[0030] The push rod box has a fixing hole 17, which corresponds to the fixing hole on the push rod box fixing ring 5. The push rod box 14 is fixed to the push rod box fixing ring 5 by bolts, ensuring that the push rod boxes 14 are evenly distributed and firmly connected, and rotate synchronously.

[0031] The push rod plate 18, which is crescent-shaped, is fixed to the lower part of the inner sealing plate 4 of the fixed plate and is located in the seed picking area of ​​the seed chamber 9. It is used to drive the roller 15 to move the push rod 6 upward to pick up the seed. After the roller 15 is disengaged, the push rod 6 resets and presses the seed through the through hole to put the seed in.

[0032] The push rod lever plate 18 is preferably fixed to the inner sealing plate 4 of the fixed plate by bolts, located in the seed-taking area of ​​the seed chamber 9. The roller 15 on the drive rod rotates and compresses the spring 16, causing the push rod 6 to move upward, opening the seed-taking gap, and allowing the seeds to enter below the push rod 6. When the roller 15 rotates to contact the push rod at this point, it is forced to move upward, and after disengaging, the push rod returns to its original position under the action of the spring 16.

[0033] In this invention, the seed support device 13 has a concave shape at the seed-taking position. As the seed-taking device rotates with the push rod, it always blocks the seed 8 behind it and works with the push rod to push the seed to the seeding area.

[0034] In this invention, the inner surface of the fixed plate assembly 1, the partial inner plane of the moving plate assembly 3, and the outer circular surface of the push rod box fixing ring 5 are combined to form the seed chamber 9, and the lower space of the chamber is used to store the seeds quantitatively filled into the seed inlet 2.

[0035] The seed chamber 9 has a seed inlet 2 at the top and stores seeds at the bottom, housing the seed-collecting area for a push-rod seed collector. This provides seed storage space to ensure continuous seed collection by the push-rod collector. Seeds are continuously carried out of the lower space by the rotation of the push-rod. The seed inlet 2 is typically located outside the inoculation box and communicates with the seed chamber 9, quantitatively filling it with seeds. This controls the flow rate of seeds entering the seed chamber 9, ensuring a stable seed supply. Seeds fall into the lower space of the seed chamber 9 by gravity through the seed inlet 2.

[0036] Secondly, this utility model provides a seeder, including a fixed disc assembly 1, a moving disc assembly 3, a duckbill assembly 7, and the aforementioned seed-supporting device for seeders. Preferably, a plurality of duckbill assemblies 7 and seed-supporting devices are arranged along the circumference, with each duckbill assembly 7 and seed-supporting device corresponding to the other on the circumference.

[0037] Among them, the fixed plate assembly 1, the moving plate assembly 3, and the duckbill assembly 7 are conventional components in the art. For example, the fixed plate assembly 1, as the fixed core component of the seed planter, is connected to the seed planter shaft 10 and is located inside the device. It has a fixed plate, which is fixed to the seed planter shaft 10. The fixed plate provides a fixed support structure, forming part of the boundary of the seed chamber 9.

[0038] The moving plate assembly 3 is located outside the fixed plate assembly 1 and is connected to the seeder shaft 10 via a bearing, allowing it to rotate relative to the fixed plate.

[0039] It includes a moving plate and a pressing plate; the moving plate and the pressing plate are connected by bolts, and the duckbill assembly 7 is fixed in a slot. It rotates around the seeder shaft 10, so that the seed-raising device passes through the seed chamber 9 to pick up seeds and the seeding area to place seeds in sequence, and the duckbill assembly 7 is simultaneously inserted into the soil for sowing.

[0040] In this invention, the moving disc assembly 3 is provided with a corresponding annular groove, the duckbill assembly 7 is locked in the groove, the duckbill assembly 7 corresponds to the through hole, so that the seed 8 is pushed into the through hole by the push rod 6 and directly enters the inner cavity of the duckbill assembly 7 to complete the precise seeding.

[0041] The seed-supporting device for hill seeders provided by this utility model is assembled on the hill seeder, and its working principle is as follows: like Figure 1-5 As shown: When the push rod rotates to the seed chamber 9 stage, the push rod deflector 18 contacts the roller 15. Due to the action of the push rod deflector 18, the roller 15 drives the push rod to move upward. The gap between the push rod and the seed picker ring 12 of the fixed plate will increase so that the seed can pass through. At this time, the seed 8 enters the lower part of the push rod. At the same time, the seed support 13 close to the rear of the push rod 6 blocks the seed. During the forward rotation, the seed support 13 always blocks the seed below the push rod 6. When the push rod 6 and the seed support device 13 rotate to near the seed chamber 9, the roller 15 on this group disengages from the push rod lever plate 18. Under the pressure of the energy stored in the spring 16, the push rod 6 presses the seeds below tightly onto the seed picker ring 12. The seed support device 13 follows behind, pushing the seeds to rotate on the seed picker ring 12 until it reaches the position where the square hole is set in the seed picker ring 12. When passing through the square hole, due to the energy stored in the push rod 6 by the spring 16, the seeds are instantly pushed into the square hole by the push rod 6 and directly enter the inner cavity of the duckbill assembly 7, completing the precise seeding. As the moving disc assembly 3 and the duckbill assembly 7 continue to rotate forward, the duckbill assembly 7 enters the soil and enters the sowing soil layer of the working surface 11. The moving nozzle is forced open, and the seeds fall into the holes made by the duckbill assembly 7, thus completing the whole process of seed picking, seed transportation, instant sowing, hole formation, and timely sowing into the holes.

[0042] The above description is merely a preferred embodiment of this utility model. However, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art based on the technical solution and improved concept of this utility model should be covered within the scope of protection of this utility model.
