Description

Technical Field

[0001] This utility model relates to the field of three-dimensional planting device technology, and more specifically, to a three-dimensional planting and transplanting device for forest seedlings. Background Technology

[0002] In large-scale automated forest seedling nurseries, three-dimensional planting and transplanting devices are the core equipment for achieving efficient cultivation, transportation and management of forest seedlings. They drive planting racks or planting trays to circulate in a three-dimensional space via chains, which can make full use of the factory space and increase the seedling density.

[0003] In existing technologies, planting racks are mostly directly mounted on chains via movable connectors, relying solely on their own weight to maintain a stable posture during transport. For example, Chinese patent document CN212259940U discloses a gravity-circulating planting rack device. In this document, the planting rack is raised or lowered along an inclined track, and then naturally falls down by gravity to maintain verticality. However, to prevent the planting rack from shifting or tilting due to inertia, the chain's movement speed is strictly controlled within a low range. In large-scale automated seedling cultivation scenarios, it is necessary to regularly irrigate and fertilize a large number of seedlings. The low-speed chain transport results in excessively long single-operation cycles, restricting the overall efficiency of seedling cultivation. Utility Model Content

[0004] This invention proposes a three-dimensional planting and transplanting device for forest seedlings, which improves the stability of the planting tray during transportation, thereby increasing the chain speed, reducing the cycle time of a single operation, and improving the overall seedling efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a three-dimensional planting and transplanting device for forest seedlings, comprising two chains, with multiple planting trays between the two chains. Each planting tray is fixedly connected to a connecting shaft at both ends. A limiting sleeve is rotatably connected to the outer end of the connecting shaft. A limiting block is fixedly connected to the inner wall of the limiting sleeve. A limiting groove is formed on the outer wall of the connecting shaft. The end of the limiting block extends into the limiting groove and is slidably connected to its inner wall, so that the limiting block can rotate within the angle range defined by the limiting groove. The limiting sleeve is movably mounted on the chain.

[0006] Preferably, one end of the connecting shaft located inside the limiting sleeve protrudes outward to form an extension shaft, and a bearing is fixedly connected to the inner wall of the limiting sleeve. The bearing is sleeved on the extension shaft and fixedly connected to it.

[0007] Through the above technical solution, the bearing reduces the friction between the connecting shaft and the limiting sleeve during rotation. When the chain drives the limiting sleeve to move, and the planting tray needs to adjust its posture according to the movement, the connecting shaft can rotate more smoothly within the limiting sleeve, ensuring the flexibility of the planting tray during movement and reducing jamming caused by poor rotation.

[0008] Preferably, the outer wall of the limiting sleeve has a fixing hole, and the inner wall of the fixing hole has two threaded grooves. The limiting block is inserted into the fixing hole. The top of the limiting block has two mounting holes, and the inner wall of each mounting hole is fitted with a fastening bolt. The ends of the fastening bolts are threadedly connected to the threaded grooves. A fixing shaft is fixedly connected to the end of the limiting sleeve, and the end of the fixing shaft is rotatably connected to the chain connecting plate.

[0009] Through the above technical solution, the limiting block can be securely installed on the limiting sleeve, ensuring the limiting effect of the limiting block on the connecting shaft and ensuring the stable operation of the planting tray during movement. Loosen the fastening bolts, adjust the position of the limiting block in the limiting groove, and then tighten the fastening bolts to facilitate the installation of the limiting block.

[0010] Preferably, the three-dimensional planting and transplanting device for tree seedlings further includes two support frames, with a top beam and a bottom beam fixedly connected between the two support frames. Two first sprockets are rotatably connected to the relatively close sides of the two support frames, and two second sprockets are rotatably connected to the relatively close sides of the two support frames. The first and second sprockets located on the same support frame are used to transport the chain and support the chain in an upwardly convex trapezoidal shape.

[0011] Through the above technical solution, the two support frames are connected by a top beam and a bottom beam, forming a stable frame structure, which enhances the stability and load-bearing capacity of the device. The first and second sprockets are rotatably connected to the support frames, and cooperate with the chain to support the chain in an upwardly convex trapezoidal shape and drive the chain for conveying.

[0012] The beneficial effects of this utility model, achieved through the above technical solution, are as follows: 1. By setting multiple planting trays between two chains and incorporating connecting shafts, limiting sleeves, limiting blocks, and limiting grooves, the shape and size of the limiting grooves limit the rotation angle range of the limiting blocks. When the limiting blocks rotate to the boundary of the limiting grooves, they can no longer rotate, allowing the planting trays to maintain a stable posture during movement. This reduces the offset and tilting of the planting trays due to inertia. Compared to traditional planting racks that rely solely on gravity for stability, this improves the stability of the planting trays during transportation, thereby increasing the chain's operating speed, reducing the cycle time for a single operation, and improving overall seedling efficiency.

[0013] 2. The limiting block can be securely installed on the limiting sleeve, ensuring the limiting effect of the limiting block on the connecting shaft and ensuring the stable operation of the planting tray during movement. Loosen the fastening bolts, adjust the position of the limiting block in the limiting groove, and then tighten the fastening bolts to facilitate the installation of the limiting block.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0017] like Figures 1-3 As shown, a three-dimensional planting and transplanting device for forest seedlings includes two chains 6, with multiple planting trays 7 between the two chains 6. Both ends of the planting trays 7 are fixedly connected to connecting shafts 8. The outer ends of the connecting shafts 8 are rotatably connected to limiting sleeves 9. The inner walls of the limiting sleeves 9 are fixedly connected to limiting blocks 16. The outer walls of the connecting shafts 8 have limiting grooves 11. The ends of the limiting blocks 16 extend into the limiting grooves 11 and are slidably connected to their inner walls, so that the limiting blocks 16 can rotate within the angle range defined by the limiting grooves 11. The limiting sleeves 9 are movably mounted on the chains 6.

[0018] Multiple planting trays 7 are set between two chains 6, and a connecting shaft 8, a limiting sleeve 9, a limiting block 16, and a limiting groove 11 are provided. The shape and size of the limiting groove 11 limit the rotation angle range of the limiting block 16. When the limiting block 16 rotates to the boundary of the limiting groove 11, it can no longer rotate, so that the planting tray 7 can maintain a stable posture during movement, reducing the offset and tilt of the planting tray 7 due to inertia. Compared with the traditional planting frame that relies solely on gravity to maintain stability, the stability of the planting tray 7 during transportation is improved, which in turn can increase the running speed of the chain 6, reduce the single operation cycle, and improve the overall seedling efficiency.

[0019] like Figure 3 As shown, one end of the connecting shaft 8 located inside the limiting sleeve 9 protrudes outward to form an extension shaft 13. A bearing 12 is fixedly connected to the inner wall of the limiting sleeve 9. The bearing 12 is sleeved on the extension shaft 13 and fixedly connected to it.

[0020] The bearing 12 reduces the friction between the connecting shaft 8 and the limiting sleeve 9 during rotation. When the chain 6 drives the limiting sleeve 9 to move, and the planting tray 7 needs to adjust its posture according to the movement, the connecting shaft 8 can rotate more smoothly within the limiting sleeve 9, ensuring the flexibility of the planting tray 7 during movement and reducing jamming caused by poor rotation.

[0021] like Figure 3 and Figure 4 As shown, the outer wall of the limiting sleeve 9 has a fixing hole 14, and the inner wall of the fixing hole 14 has two threaded grooves 15. The limiting block 16 is inserted into the fixing hole 14. The top of the limiting block 16 has two mounting holes 17, and the inner wall of each mounting hole 17 is fitted with a fastening bolt 18. The ends of the fastening bolts 18 are threaded into the threaded grooves 15 respectively. A fixing shaft 10 is fixedly connected to the end of the limiting sleeve 9, and the end of the fixing shaft 10 is rotatably connected to the connecting plate of the chain 6.

[0022] The limiting block 16 can be securely installed on the limiting sleeve 9, ensuring the limiting effect of the limiting block 16 on the connecting shaft 8 and ensuring the stable operation of the planting tray 7 during movement. Loosen the fastening bolt 18, adjust the position of the limiting block 16 in the limiting groove 11, and then tighten the fastening bolt 18 to facilitate the installation of the limiting block 16.

[0023] like Figure 1 As shown, the three-dimensional planting and transplanting device for forest seedlings also includes two support frames 1, with a top beam 2 and a bottom beam 3 fixedly connected between them. Two first sprockets 4 are rotatably connected to the relatively close side of the two support frames 1, and two second sprockets 5 are rotatably connected to the relatively close side of the two support frames 1. The first sprockets 4 and second sprockets 5 located on the same support frame 1 are used to transport the chain 6 and support the chain 6 in an upwardly convex trapezoidal shape.

[0024] The two support frames 1 are connected by a top beam 2 and a bottom beam 3, forming a stable frame structure that enhances the stability and load-bearing capacity of the device. The first sprocket 4 and the second sprocket 5 are rotatably connected to the support frame 1, and cooperate with the chain 6 to support the chain 6 in an upwardly convex trapezoidal shape and drive the chain 6 for conveying.

[0025] This device only shows the structure on one set of support frames 1. However, for large-scale planting, it can be composed of multiple sets of support frames. An external motor drives the second sprocket 5 on one of the support frames 1 to rotate, which in turn drives the chain 6 to rotate.

[0026] When in use, the chain 6 starts to move under the drive of the power device, and the chain 6 drives multiple planting trays 7 to move, realizing the tilting, lifting and lowering movement of the planting trays 7.

[0027] During movement, the planting tray 7 remains stable under its own weight. When the chain 6 drives the limiting sleeve 9 to move, if the planting tray 7 is subjected to external forces, such as during turning, acceleration, or deceleration, the planting tray 7 may tend to tilt or deviate. At this time, the connecting shaft 8 will rotate relative to the limiting sleeve 9, and the limiting block 16 will slide within the limiting groove 11. The shape and size of the limiting groove 11 limit the rotation angle range of the limiting block 16. When the limiting block 16 rotates to the boundary of the limiting groove 11, it can no longer rotate, thereby limiting the further rotation of the connecting shaft 8 and ensuring that the planting tray 7 remains stable within a certain angle range, without excessive tilting or deviation.

[0028] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
