Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to a duckbill transplanting structure for transplanting rice seedlings. Background Technology
[0002] In the field of agricultural seedling transplanting, traditional duckbill transplanting structures generally suffer from problems such as high soil penetration resistance, inflexible duckbill opening and closing, and insufficient seedling planting accuracy. Existing equipment typically uses cylindrical or ordinary conical duckbills, resulting in significant soil compression resistance during insertion, which can easily damage seedling roots. Furthermore, the duckbill closure relies on mechanical linkage or gravity, making it prone to seedling leakage or trapping, thus affecting transplanting efficiency. In addition, traditional structures have poor motion coordination, making it difficult to precisely control transplanting depth and spacing, leading to fluctuations in seedling survival rates. Utility Model Content
[0003] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a duckbill transplanting structure for seedling transplanting, including an eccentric plate and a concentric plate assembly fixed on the eccentric plate. The concentric plate assembly has several duckbill connecting assemblies arranged circumferentially. A duckbill transplanting assembly is rotatably connected within each duckbill connecting assembly. The duckbill transplanting assembly includes a seedling receiving port, a soil inserter disposed below the seedling receiving port, and an opening / closing duckbill assembly disposed outside the soil inserter. The soil inserter includes a soil inserting ring that engages with the outlet of the seedling receiving port. The soil inserting ring has two sides respectively... The assembly includes a connecting post, with an installation shaft at the end of the connecting post furthest from the soil entry ring. The opening and closing duckbill assembly includes a first duckbill flap and a second duckbill flap, which are positioned opposite each other on both sides of the soil entry ring and sleeved on the connecting post. A U-shaped connector is provided on the side of the first duckbill flap and the second duckbill flap furthest from the soil entry ring. The U-shaped connector is rotatably connected to the connecting post via a rotating shaft. A torsion spring is provided between the rotating shafts of the first duckbill flap and the second duckbill flap, so that the first duckbill flap and the second duckbill flap are in a closed state when no external force is applied.
[0004] Preferably, the first and second duckbill lobes form a conical duckbill with an opening that gradually decreases from top to bottom. The width of the conical duckbill along the central axis of the connecting post is less than its width along the vertical direction of the central axis of the connecting post, so that the conical duckbill is a flat cone shape.
[0005] Preferably, the upper part of the seedling inlet is an inverted cone-shaped seedling inlet, and the lower part is a seedling outlet corresponding to the soil inserter.
[0006] Preferably, the concentric disk assembly includes an active concentric disk and a passive concentric disk spaced apart, the centers of the active concentric disk and the passive concentric disk are connected by a central shaft, and the active concentric disk is fixed to the surface of the eccentric disk and rotates with the eccentric disk.
[0007] Preferably, the duckbill connecting assembly includes a first connecting plate and a second connecting plate disposed on both sides of the duckbill transplanting assembly. The first connecting plate and the second connecting plate are rotatably connected to the mounting shafts on both sides of the duckbill transplanting assembly via a first bearing. The first connecting plate is rotatably connected to the eccentric disk via a connecting rod assembly.
[0008] Preferably, the linkage assembly includes a linkage arm, one end of which is rotatably connected to the eccentric disk via a second bearing and a pin, and the other end is fixedly connected to the mounting shaft on one side of the duckbill transplanting assembly via a connecting hole.
[0009] Preferably, the length of the connecting arm is equal to the eccentricity length of the concentric disk assembly and the eccentric disk connection.
[0010] Preferably, the mounting shaft is a polygonal shaft, and a pin is inserted into the mounting shaft after it passes through the connecting hole.
[0011] The advantages of this utility model compared with the prior art are as follows: In this invention, the flat conical duckbill is flat and cuts the soil laterally when inserted into the ground, achieving low resistance and high transplanting efficiency. Simultaneously, the flat conical duckbill protects the seedlings while providing sharp penetration. Due to its smooth inner surface, the seedlings are quickly dropped, preventing seedlings from being stuck or trapped. The interconnected design of the eccentric and concentric discs and connecting rods ensures that the seedlings always fall vertically into the soil, improving planting uprightness. Multiple circumferentially distributed duckbill components can adapt to different row spacing requirements. By adjusting the number and spacing of the circumferential duckbill components on the concentric discs, it is suitable for transplanting various seedlings, demonstrating good versatility.

[0024] Example
[0025] Combined with appendix Figure 1-7 This embodiment discloses a duckbill transplanting structure for seedling transplanting, including an eccentric plate 1 and a concentric plate assembly 2 fixed on the eccentric plate 1. Several duckbill connecting assemblies 3 are circumferentially arranged on the concentric plate assembly 2. A duckbill transplanting assembly 4 is rotatably connected within the duckbill connecting assemblies 3. The duckbill transplanting assembly 4 includes a seedling receiving port 401, a soil inserter 402 disposed below the seedling receiving port 401, and an opening / closing duckbill assembly 403 disposed outside the soil inserter 402. The soil inserter 402 includes components connected to the seedling receiving port... The soil-entry ring 402a is connected to the outlet of 401. Connecting posts 402b are respectively provided on both sides of the soil-entry ring 402a. An installation shaft 402c is respectively provided at the end of the connecting posts 402b away from the soil-entry ring 402a. The upper part of the seedling inlet 401 is an inverted conical seedling inlet 401a, and the lower part is a seedling outlet 401b corresponding to the soil-entry device 402. The opening and closing duckbill assembly 403 includes a first duckbill flap 403 that is positioned opposite each other on both sides of the soil-entry ring 402a and sleeved on the connecting posts 402b. a. A second duckbill flap 403b. U-shaped connectors 403c are respectively provided on the side of the first duckbill flap 403a and the second duckbill flap 403b away from the soil-entry ring 402a. The U-shaped connectors are rotatably connected to the connecting post 402b via a rotating shaft 403d. A torsion spring 403e is provided between the rotating shafts 403d of the first duckbill flap 403a and the second duckbill flap 403b, so that the first duckbill flap 403a and the second duckbill flap 403b are closed when no external force is applied. State; The first duckbill petal 403a and the second duckbill petal 403b form a conical duckbill with the opening gradually decreasing from top to bottom. The width of the conical duckbill along the central axis 203 of the connecting post 402b is smaller than its width along the vertical direction of the central axis 203 of the connecting post 402b, making the conical duckbill flat and conical. This shape of duckbill not only protects the seedlings but also has the function of sharply penetrating the soil. Because the inner surface is flat and smooth, the seedlings are dropped quickly, so there will be no seedling-bearing or seedling-clamping phenomena.
[0026] The concentric disk assembly 2 includes an active concentric disk 201 and a passive concentric disk 202 spaced apart. The centers of the active concentric disk 201 and the passive concentric disk 202 are connected by a central shaft 203. The active concentric disk 201 is fixed to the surface of the eccentric disk 1 and rotates with the eccentric disk 1.
[0027] The duckbill connecting assembly 3 includes a first connecting plate 301 and a second connecting plate 302 disposed on both sides of the duckbill transplanting assembly 4. The first connecting plate 301 and the second connecting plate 302 are rotatably connected to the mounting shafts 402c on both sides of the duckbill transplanting assembly 4 via a first bearing 304. The first connecting plate 301 is rotatably connected to the eccentric disk 1 via a connecting rod assembly. The connecting rod assembly includes a connecting rod arm 303. One end of the connecting rod arm 303 is rotatably connected to the eccentric disk 1 via a second bearing 305 and a pin 306, and the other end is fixedly connected to the mounting shaft 402c on one side of the duckbill transplanting assembly 4 via a connecting hole. The mounting shaft 402c is a polygonal shaft, and a pin 307 is inserted into the mounting shaft 402c after it passes through the connecting hole.
[0028] In practical implementation, the eccentric disk rotates with the power unit, driving the concentric disk assembly to move circumferentially. The duckbill transplanting assembly is connected to the concentric disk assembly through the duckbill connecting assembly. The eccentric disk and the active concentric disk have the same radius, and the eccentricity and connecting rod arm length are equal, making the eccentric mechanism composed of the eccentric disk and the concentric disk assembly a parallelogram mechanism. The eccentric disk and the active concentric disk act as two equivalent cranks. During the rotation of the planter, as long as the line connecting the eccentric disk and the active concentric disk remains horizontal, the connecting rod arm can always maintain a translational posture, and the angle between it and the ground remains unchanged. The mounting shaft of the duckbill transplanting assembly is fixed to the connecting rod arm and moves accordingly, so that the duckbill transplanting assembly is always perpendicular to the ground, ensuring that the seedlings always fall into the soil in a vertical posture, which helps to improve the uprightness of the planting.
[0029] When the flat-conical beak of the duckbill transplanting component contacts the soil, the flat-conical beak petals reduce the resistance to soil penetration, allowing the component to quickly insert into the soil. At this time, the lateral pressure of the soil on the beak petals is transmitted through the U-shaped connector and the rotating shaft, overcoming the torsion spring force and forcing the first and second beak petals to open around the connecting column. The soil insertion ring penetrates deeper into the soil with the soil inserter, and the seedling outlet releases the seedling into the pit. When the eccentric disc rotates to the lifting stroke, the duckbill transplanting component moves upward and detaches from the soil. After the soil pressure is lost, the torsion spring force causes the first and second beak petals to return to their original position and close, preventing soil or debris from entering the seedling inlet. Multiple circumferentially distributed duckbill connecting components rotate with the concentric disc, cyclically completing the "seedling inlet-soil insertion-seedling release-reset" process, achieving continuous transplanting operations.
