Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural technology, specifically a seedling transplanting device for agricultural planting. Background Technology
[0002] Seedling transplanting in agricultural planting refers to the agricultural operation technique of removing robust seedlings from their initial seedling environment (seedbed, seedling tray, nutrient pot, etc.) after the crop seedling stage and replanting them in fields, greenhouses, or other cultivation containers according to a certain plant spacing and planting depth. This technique is widely used in the cultivation of vegetables (such as tomatoes, cucumbers, and peppers), cash crops (such as cotton and tobacco), and some food crops (such as rice). The core purpose is to create a more suitable space and environment for seedling growth, avoid the adverse effects of low temperatures, pests, and diseases during the seedling stage, and improve land utilization through reasonable dense planting. Before transplanting, seedlings need to be hardened off according to the characteristics of the crop to enhance their resistance to adverse conditions. During transplanting, care should be taken to maintain the integrity of the root system and reduce mechanical damage. Some crops also require auxiliary measures such as watering, fertilization, and mulching to promote seedling establishment and survival.
[0003] An investigation revealed that a Chinese utility model patent (or invention patent) discloses a seedling transplanting device for agricultural planting (publication number: CN222322187U). The device includes a main structure with a loading structure inside, and a sliding structure at the upper end of the loading structure. A rail is provided at the connection between the main structure and the loading structure. A slide rail is provided at the connection between the main structure and the sliding structure. By energizing a motor to drive a screw to rotate, a first slider moves a nozzle from one side to the other, thus irrigating the plants on the upper part of the planting board. The nozzle slides with the assistance of a second slider and the slide rail, ensuring more even spraying and improving the survival rate of the plants. The device includes a planting board and a collection frame. Multiple groups of plants are arranged inside a groove at the top of the planting board, and a through hole is provided at the bottom of the planting board to allow excess water to fall into the collection frame.
[0004] Although the aforementioned patent achieves this by powering a motor to rotate a screw, causing a first slider to move a nozzle from one side to the other to irrigate the plants on the upper part of the planting board, and the nozzle slides with the assistance of a second slider and a slide rail, resulting in more even spraying and improved plant survival rate, its internal mechanism cannot secure transplanting pots of different sizes. This leads to the transplanting pots tilting or collapsing during transportation, resulting in a reduced survival rate. Therefore, this utility model provides a seedling transplanting device for agricultural planting to solve the above problems. Utility Model Content

[0018] Beneficial effects
[0019] 1. In this utility model, when the worker places the transplanting pot into the placement slot, pulling the pull plate can cause the locking post to move and stretch the second spring, causing the locking post to disengage from its initial limit. Then, pressing the pressing block will push the sliding rod forward inside the transplanting plate, thereby pushing the extrusion plate to slide towards the transplanting pot until it is tightly attached to the outer wall of the transplanting pot. During this process, the sliding plate will compress the first spring and store elastic potential energy, while the locking post will be precisely aligned with the slot in the pressing block. After releasing the pull plate, the second spring releases elastic potential energy, pulling the locking post into the slot, thereby locking the sliding rod and allowing the extrusion plate to maintain a continuous clamping force on the transplanting pot, ensuring the stability of the transplanting pot during the movement and transportation of the device, and reducing the problem of seedling damage caused by the transplanting pot tipping over.
[0020] 2. In this utility model, the starting motor can drive the rotating rod to rotate. With the help of the thread engagement between the external thread and the threaded sleeve, the threaded sleeve will drive the transplanting plate to move synchronously through the connecting block. At the same time, the sliding ring on the right side of the transplanting plate slides smoothly along the upright, ensuring that the transplanting plate remains horizontal and stable during the displacement process. When it is necessary to store or retrieve the transplanting pot, the height of the transplanting plate can be adjusted to leave sufficient operating space around the placement slot. The staff is not limited by a fixed spacing and can more easily put the transplanting pot into the placement slot or take it out of the slot, which greatly reduces the difficulty of operation and improves the efficiency of transplanting work.

[0027] 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.
[0028] This utility model provides a seedling transplanting device for agricultural planting, such as... Figures 1 to 3As shown, the device includes an outer frame 1, which serves as the basic supporting structure for the entire seedling transplanting device used in agricultural planting. Multiple transplanting mechanisms are installed inside the outer frame 1. An adjustment mechanism is located on the left side of the inner side of the outer frame 1, and a closing mechanism is located on the front side of the outer frame 1. Each transplanting mechanism includes a transplanting plate 2, which matches a sliding track inside the outer frame 1 to ensure smooth displacement under the action of the adjustment mechanism. The outer surfaces of the multiple transplanting plates 2 are slidably connected to the inner surface of the outer frame 1. Multiple placement slots 3 are provided inside the transplanting plates 2, serving as the direct support for the transplanting pots. The transplanting plates are evenly distributed to achieve batch transplanting. Multiple sliding rods 4 are slidably connected inside the transplanting plate 2. Workers can control the forward and backward movement of the sliding rods 4 inside the transplanting plate 2 by pressing or releasing the pressing block 9. Each sliding rod 4 has a spring assembly on its rear side, providing power support for the reset and clamping action of the sliding rod 4. Each sliding rod 4 is equipped with a spring assembly on its rear side to ensure stable and reliable movement. Two rotating rods 7 are rotatably connected to the left and right sides of each sliding rod 4. The rotating rods 7 are located away from the sliding rods 4. Each side is rotatably connected to a pressing plate 8. The rotating rod 7 can rotate flexibly, converting the linear motion of the sliding rod 4 into the lateral motion of the pressing plate 8, thereby clamping or releasing the transplanting pot. The pressing plate 8 is slidably connected to the inside of the transplanting plate 2. Pressing blocks 9 are fixedly connected to the front of each of the multiple sliding rods 4. When the sliding rod 4 moves forward, the pressing plate 8 is pushed towards the transplanting pot by the transmission action of the rotating rod 7 until it is in close contact with the outer wall of the transplanting pot, generating a certain amount of squeezing force, thereby stably clamping the transplanting pot in the placement groove 3 and preventing it from moving or being transported. During the transplanting process, if the transplanting pot shakes or tipps over, to ensure the safety of the seedlings, multiple pressing blocks 9 are provided with slots 10 inside. When the sliding rod 4 moves forward to the appropriate position, it drives the pressing plate 8 to clamp and fix the transplanting pot. The slots 10 are then aligned with the positions of the locking posts 11. At this time, the locking posts 11 are locked into the slots 10 under the action of the second spring 12, locking the sliding rod 4 in the current position and preventing the sliding rod 4 from resetting under the action of the first spring 6. This ensures that the clamping force of the pressing plate 8 on the transplanting pot is continuous and ensures the stability of the transplanting pot. Multiple locking components are provided inside the multiple transplanting plates 2.
[0029] like Figure 2 and Figure 3The multiple elastic components shown all include sliding plates 5. The front sides of the multiple sliding plates 5 are respectively fixedly connected to the rear sides of the multiple sliding rods 4. The function of the sliding plates 5 is to transmit the movement of the sliding rods 4 to the springs 6, and also to guide and limit the springs 6 to prevent them from deviating during compression or extension, thus ensuring the normal operation of the elastic components. Each sliding plate 5 has a spring 6 on its rear side. One end of the spring 6 is fixedly connected to the inside of the transplanting plate 2, and the other end of the spring 6 is fixedly connected to the rear side of the sliding plate 5. When the worker presses the pressing block 9 and pushes the sliding rods 4 forward, the sliding rods 4 drive the sliding plates 5 forward synchronously, thereby squeezing the springs 6, causing the springs 6 to undergo compression deformation and store elastic potential energy. When the operator releases the pressing block 9 or removes the external force applied to the sliding rod 4, spring 6 releases its stored elastic potential energy, pushing the sliding plate 5 backward and thus resetting the sliding rod 4, preparing for the next clamping operation. Multiple locking components include locking posts 11, with the external slidable connection of the locking posts 11 to the inside of the transplanting plate 2 and the external slidable connection of the locking posts 11 to the inside of the locking groove 10. By pulling the pull plate 13, the operator can move the locking posts 11 to displace them, thus releasing the lock. Under the elastic force of spring 12, the locking posts 11 always tend to move towards the locking groove 10, ensuring that the locking groove 10 and the locking posts 11 are aligned. The locking mechanism allows for quick and accurate insertion into the slot 10, achieving reliable locking. Multiple locking posts 11 are fitted with springs 2 12. When the operator releases the pull plate 13, the springs 2 12 release their elastic potential energy, pulling the locking posts 11 towards the slot 10 until they are engaged, thus locking the sliding rod 4. Each locking post 11 has a pull plate 13 fixedly connected to its top. By pulling the pull plate 13 upwards, the operator can easily slide the locking posts 11 upwards inside the transplanting plate 2, causing them to slide out of the slot 10 and releasing the lock on the sliding rod 4. This allows the sliding rod 4 to reset under the action of spring 1 6, enabling the transplanting pot to be removed.
[0030] like Figures 2 to 4The adjustment mechanism shown includes a motor 14, which serves as the power source for the adjustment mechanism. The bottom of the motor 14 is mounted on the top left side of the outer frame 1. A rotating rod 15 is fixedly connected to the output end of the motor 14. After the motor 14 starts, it can drive the rotating rod 15 to rotate synchronously. Multiple external threads 16 are provided on the outside of the rotating rod 15. The pitch of the external threads 16 directly affects the displacement speed of the threaded sleeve 17, i.e., the adjustment speed of the transplanting plate 2. The operator can select an appropriate pitch of the external thread 16 according to actual needs to control the adjustment speed of the transplanting plate 2. Multiple threaded sleeves 17 are connected to the external threads of the rotating rod 15. A connecting block 18 is fixedly connected to the outside of each threaded sleeve 17. The right side of the connecting block 18 is fixedly connected to the left side of the transplanting plate 2. The main function of the connecting block 18 is to act as a connecting bridge between the threaded sleeve 17 and the transplanting plate 2, transmitting the linear displacement of the threaded sleeve 17 to the transplanting plate 2, driving the transplanting plate 2 to move synchronously inside the outer frame 1. A vertical rod 19 is fixedly connected to the right side of the inside of the outer frame 1. Multiple transplanting plates 2 are fixedly connected to the right side of each of the two connecting blocks 21. The main function of the upright 19 is to provide guidance and support for the right side of the transplanting plate 2. Together with the rotating rod 15, it ensures that the transplanting plate 2 will not tilt or shake during the displacement process, and ensures that the transplanting plate 2 is always in a horizontal state, providing a stable support environment for the transplanting pots in the placement trough 3. Multiple connecting blocks 21 are fixedly connected to the inside of each of the two connecting blocks 21. The inside of the sliding ring 20 is slidably connected to the outside of the upright 19. The main function of the sliding ring 20 is to connect the right side of the transplanting plate 2 to the upright 19. When the transplanting plate 2 is displaced, it drives the sliding ring 20 to slide synchronously outside the upright 19. The closing mechanism includes two rotating doors 22. The rear side of the two rotating doors 22 is set on the front side of the outer frame 1. The front side of the two rotating doors 22 is fixedly connected to the handle 23. The bottom four corners of the outer frame 1 are fixedly connected to universal wheels 24. The four universal wheels 24 are evenly distributed, which can provide stable support for the device and ensure that the device will not tip over when stationary. The 24 casters have a 360-degree rotation function, allowing workers to easily change the direction of movement of the device. Whether in narrow field paths or spacious greenhouses, the device can be moved flexibly, greatly improving its mobility and ease of use.
[0031] Working Principle: When using this seedling transplanting device for agricultural planting, firstly, the rotating door 22 can be opened by pulling the handle 23, thus exposing the transplanting plate 2 inside the outer frame 1. Then, the motor 14 can be started as needed to drive the rotating rod 15 to rotate. Then, through the threaded connection between the threaded sleeve 17 and the external thread 16, the connecting block 18 can be displaced, thereby realizing the overall displacement of the transplanting plate 2. This allows for adjustment of the internal position of the transplanting plate 2 to accommodate seedlings of different heights. At the same time, it facilitates the placement and removal of the transplanting pots inside the trough 3, leaving sufficient storage and retrieval space. Then, the pull plate 13 can be pulled to move the locking post 11, thereby stretching the spring 12. At this point, the locking pin 11 will slide out from inside the second spring 12, and then the pressing block 9 can be pressed inward, causing the sliding rod 4 to move. At this time, the rotation between the sliding rod 4 and the rotating rod 7 will cause the pressing plate 8 to move, thereby clamping and fixing the transplanting pot, thus ensuring the stability of the transplanting pot. At this time, the sliding plate 5 will move, which will compress the first spring 6, and at the same time, the locking pin 11 will align with the inside of the second spring 12. Then, the pull plate 13 will be released, and the locking pin 11 will engage with the inside of the second spring 12, thereby locking the sliding rod 4. At this time, the transplanting pot can be clamped and fixed. When it is necessary to remove the transplanting pot, the above steps can be reversed.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
