Description

Technical Field

[0001] This utility model relates to the field of transfer device technology, specifically a seedling transfer device for agricultural planting. Background Technology

[0002] In agricultural planting, especially in the cultivation of crops such as vegetables, rice, and melons that rely on seedling transplanting, the transportation of seedlings from the seedling shed to the field is crucial, directly affecting seedling survival rate and subsequent planting efficiency. Currently, small and medium-sized growers mostly use manual carrying or simple bamboo or plastic baskets to transport seedlings. This method not only requires a large amount of manpower but also has a limited capacity for each transport, making it difficult to meet the efficiency requirements of large-scale planting. Especially during the busy transplanting season, untimely transportation can easily delay the optimal planting time.

[0003] Traditional transportation methods also have significant shortcomings in seedling protection: simple baskets lack fixed protective structures, and seedlings are prone to leaf breakage, root loosening, or substrate loss due to bumps and collisions during transportation, resulting in decreased seedling vitality, prolonged recovery period after transplanting, and even seedling death; some growers stack seedlings to increase the amount transported at one time, which further aggravates squeezing damage, causes unnecessary seedling loss, and increases planting costs.

[0004] Furthermore, while existing mechanized transport equipment can improve efficiency, it suffers from poor compatibility: most devices can only be used with specific models of agricultural machinery and lack targeted shock absorption designs. When moving on muddy or undulating surfaces in the field, vibrations are transmitted to the seedling-bearing area, still causing damage to the seedlings. At the same time, these devices have complex loading and unloading structures, requiring additional tools for operation, making it difficult to quickly pick up and place seedlings, and thus failing to meet the actual needs of flexible field transport. Based on these pain points, there is an urgent need for an agricultural seedling transport device that balances efficient transport, seedling protection, and ease of operation. Utility Model Content

[0015] 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. Example

[0016] like Figure 1-4 As shown, an embodiment of this utility model proposes an agricultural seedling transfer device, which includes a trailer frame 1. The trailer frame 1 is equipped with a fence 2 on three sides above it. The trailer frame 1 is composed of an interlaced frame and a trailer plate, which serves as the core load-bearing foundation of the device and provides fixed support for the fence 2. A bracket 3 is fixedly connected to the front of the trailer frame 1. The front end of the bracket 3 is connected to the trailer hook 4 through a bolt thread. A plate is fixedly connected to the rear end of the trailer frame 1. A door panel 5 is rotatably connected to the plate through a hinge. A connecting rod 6 is rotatably connected to the door panel 5. The connecting rod 6 is engaged in an L-shaped buckle 7. The rear end plate of the trailer frame 1 provides a base for the rotation of the door panel 5 through a hinge. The door panel 5 can be opened and closed around the hinge. The connecting rod 6 on the door panel 5 cooperates with the L-shaped buckle 7 fixed to the rear end plate of the trailer frame 1. After the door panel 5 is closed, the connecting rod 6 is engaged in the L-shaped buckle 7, which can lock the position of the door panel 5 and form a closed structure at the rear end of the device to prevent the seedlings from falling off. A connecting rod 8 is fixedly connected to the bottom of the trailer frame 1. A leaf spring 9 is rotatably fixedly connected to the bottom of the connecting rod 8. A fastener 10 is fixedly connected to the center of the bottom of the leaf spring 9. A bearing seat 11 is fixedly connected to the bottom of the fastener 10. A rotating shaft 12 is inserted and fixedly connected to the bearing seat 11. Mounting plates 13 are fixedly connected to both ends of the rotating shaft 12. Tires 14 are bolted onto the mounting plates 13. During transport, the traction force of external agricultural machinery is transmitted to the trailer frame 1 through the trailer hook 4. The trailer frame 1 drives the rotating shaft 12 to rotate in sequence through the connecting rod 8, leaf spring 9, fastener 10, and bearing seat 11. The rotating shaft 12 then drives the tires 14 to roll through the mounting plates 13, realizing the overall movement of the device. At the same time, the leaf spring 9 can generate elastic deformation when the road surface is bumpy, buffering the impact of vibration on the seedlings on the trailer frame 1. The multi-structure linkage not only ensures the mobility of the device but also improves the stability of seedling transport.

[0017] The working principle of this seedling transfer device for agricultural planting is as follows: In use, first, rotate the connecting rod 6 on the door panel 5 to detach it from the L-shaped buckle 7 fixed to the rear end plate of the trailer frame 1. After opening the door panel 5, place the seedlings or seedling trays with seedlings onto the trailer frame 1, which consists of an interlocking frame and trailer plates. The three-sided installed fence 2, composed of vertical bars and evenly distributed horizontal bars, prevents the seedlings from falling off the sides during transfer. After loading is complete, close the door panel 5 and reconnect the connecting rod 6 to the L-shaped buckle 7 for sealing and fixation. Then, use the front support of the trailer frame 1... The trailer hook 4 on the trailer frame 3 connects to agricultural machinery such as tractors, which provide traction to move the device. During the movement, the leaf spring 9 connected to the bottom connecting rod 8 of the trailer frame 1 can buffer the impact of road bumps on the seedlings. At the same time, the two rotating shafts 12 set at the bottom, one in front and one behind, are fixed to the bottom of the leaf spring 9 by fasteners 10 through bearing seats 11, so as to rotate flexibly and drive the tires 14 on the mounting plates 13 at both ends of the rotating shafts 12 to roll, thereby completing the stable transfer of seedlings from the seedling area to the planting area. When unloading, the door panel 5 can be opened again to easily take out the seedlings.

[0018] like Figure 4 As shown, in some embodiments, the trailer frame 1 is composed of an interlaced skeleton and trailer plates, with the trailer plates fixedly installed on the skeleton; the interlaced structure is constructed by connecting metal rods to form a frame, which ensures structural stability and reduces its own weight, avoiding excessive weight of the device and increasing the burden of movement.

[0019] like Figure 4 As shown, in some embodiments, the fence 2 consists of vertical bars and horizontal bars, with the horizontal bars evenly distributed on the vertical bars, and the bottom of the vertical bars fixedly connected to the trailer frame 1, forming a grid-like protective structure. This evenly distributed design avoids blind spots while ensuring the overall structural strength of the fence 2, preventing the horizontal bars from deforming or falling off due to excessive local stress.

[0020] like Figure 3 As shown, in some embodiments, the trailer hook 4 is used to connect agricultural machinery, such as tractors; this bolted connection method not only ensures the stability of the trailer hook 4 and the bracket 3, but also facilitates the disassembly, replacement or adjustment of the trailer hook 4 during subsequent maintenance, adapting to the connection needs of agricultural machinery of different specifications.

[0021] like Figure 3 As shown, in some embodiments, the L buckle 7 is fixed to the plate, and the door panel 5 facilitates sealing and unloading; preventing the seedlings from slipping off the rear end during transportation.

[0022] like Figure 4 As shown, in some embodiments, there are two shafts 12, arranged one in front of the other below the trailer frame 1, forming a stable dual-shaft support structure.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
