[0002] Rice seedling raising is a crucial step in the rice planting process. It refers to the technical process of cultivating rice seeds into robust seedlings by artificially controlling environmental conditions, providing high-quality seedlings for subsequent field transplanting or direct seeding. Among them, the double-layer rice seedling tray is a device specifically designed for mechanized rice seedling raising. Its core structure consists of two layers, aiming to improve seedling quality, simplify the tray removal process, and adapt to the needs of mechanized operations.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Due to the many inconveniences in the process of removing the double-layer rice seedling trays that are currently widely used, specifically, when vibrating and knocking to achieve the removal of the tray, irreversible permanent deformation or breakage of the tray body is often caused, resulting in a high scrap rate of the seedling trays, which seriously affects the service life of the seedling trays and increases the seedling raising costs for users. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the double-layer rice seedling trays currently widely used are inconvenient to remove, and the tray body will be irreversibly and permanently deformed when it is shaken or knocked to remove the tray. Therefore, we propose a double-layer rice seedling tray.
[0005] To achieve the above objectives, this application adopts the following technical solution: a double-layer rice seedling tray, including a seedling tray side plate, with first sliding grooves on both sides of the bottom of the seedling tray side plate, a bottom plate slidably connected to the bottom of the seedling tray side plate, a pull plate fixedly connected to one end of the bottom plate, two first sliders fixedly connected to the top of the bottom plate, the surfaces of the first sliders slidably connected to the interior of the first sliding grooves, an inner side plate fixedly connected to the top of the bottom plate, several support plates fixedly connected to the top of the bottom plate, an inner plate installed on the top of the support plates, circular grooves on both sides of the top of the seedling tray side plate, two square grooves on the top of the pull plate, a movable rod slidably connected to the interior of the circular grooves, a limit block fixedly connected to the top of the movable rod, and one end of the limit block slidably connected to the interior of the square groove.
[0006] Preferably, one end of the side plate of the seedling tray is provided with several storage slots, and a first spring is fixedly connected inside the storage slots. The other end of the first spring is fixedly connected to the bottom plate.
[0007] Preferably, three locking blocks are fixedly connected to both sides of the inner side plate of the seedling tray, and the bottom of the locking blocks abuts against the top of the inner plate.
[0008] Preferably, a magnetic absorbing sheet is fixedly connected to the top of the support plate, and a metal sheet is fixedly connected to the bottom of the inner plate, with the magnetic absorbing sheet and the metal sheet being magnetically connected.
[0009] Preferably, a second slide groove is provided on both sides of the first slide groove, and a second slide block is fixedly connected to both sides of the first slide block, with the surface of the second slide block slidably connected to the interior of the second slide groove.

[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, an inner plate is installed inside the side panel of the seedling tray. The inner plate is installed at the top of the support plate. The limiting block is lifted, and one end of the limiting block moves out of the square groove. At this time, the limiting plate of the bottom plate is released by the pull plate. The pull plate can be pulled to move the bottom plate out of the side panel of the seedling tray. At the same time, the bottom plate moves the inner plate out of the side panel of the seedling tray. The seedlings are cultivated on the top of the inner plate. After the bottom plate is moved out of the side panel of the seedling tray, the inner plate can be removed, along with the seedlings cultivated on the top of the inner plate.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0022] Reference Figures 1-5As shown, this utility model provides a technical solution: a double-layer rice seedling tray, including a seedling tray side plate 1, with first sliding grooves 2 on both sides of the bottom of the seedling tray side plate 1, a bottom plate 3 slidably connected to the bottom of the seedling tray side plate 1, a pull plate 4 fixedly connected to one end of the bottom plate 3, two first sliders 5 fixedly connected to the top of the bottom plate 3, the surface of the first sliders 5 slidably connected to the inside of the first sliding grooves 2, an inner side plate 6 fixedly connected to the top of the bottom plate 3, several support plates 7 fixedly connected to the top of the bottom plate 3, an inner plate 8 installed on the top of the support plates 7, and circular grooves 9 on both sides of the top of the seedling tray side plate 1. Two square grooves 10 are opened on the top of the pull plate 4. A movable rod 11 is slidably connected inside the circular grooves 9, and a limit block 12 is fixedly connected to the top of the movable rod 11. One end of the limit block 12 is slidably connected to the inside of the square groove 10. By setting the inner plate 8 inside the seedling tray side plate 1, installing the inner plate 8 on the top of the support plate 7, and raising the limit block 12, the limit... When one end of the positioning block 12 moves out of the inside of the square groove 10, the limiting position of the bottom plate 3 caused by the pull plate 4 is released. The pull plate 4 can be pulled to move the bottom plate 3 out of the inside of the seedling tray side plate 1. At the same time, the bottom plate 3 moves the inner plate 8 out of the inside of the seedling tray side plate 1. The seedlings are cultivated on the top of the inner plate 8. After the bottom plate 3 is moved out of the inside of the seedling tray side plate 1, the inner plate 8 can be removed, along with the seedlings cultivated on the top of the inner plate 8. After the inner plate 8 is removed, it can be flexibly connected to the rice transplanter or manually removed. After the seedlings are removed, the inner plate 8 is put back on the top of the support plate 7, and the bottom plate 3 is reset so that one end of the limiting block 12 returns to the inside of the square groove 10, so that the pull plate 4 and the bottom plate 3 are limited again. This setting makes the seedling removal process more convenient, avoids the deformation of the plastic tray or film residue caused by traditional seedling removal methods such as vibration and knocking, increases the number of times the plastic tray can be reused, and facilitates cleaning and maintenance, extending the service life of the equipment.
[0023] Reference Figure 4 As shown in this embodiment: a plurality of storage slots 13 are provided at one end of the side plate 1 of the seedling tray. A first spring 14 is fixedly connected inside the storage slot 13. The other end of the first spring 14 is fixedly connected to the bottom plate 3. By setting the first spring 14, when the user releases the movement of the bottom plate 3, the elasticity of the first spring 14 will drive the bottom plate 3 to automatically reset, simplifying the operation process.
[0024] Reference Figure 5 As shown in this embodiment: three locking blocks 15 are fixedly connected to both sides of the inner side plate 1 of the seedling tray. The bottom of the locking block 15 abuts against the top of the inner plate 8. By setting the locking block 15, the movement of the inner plate 8 can be restricted, so as to prevent it from falling off during transportation.
[0025] Reference Figure 3As shown in this embodiment: a magnetic suction piece 16 is fixedly connected to the top of the support plate 7, and a metal sheet 17 is fixedly connected to the bottom of the inner plate 8. The magnetic suction piece 16 and the metal sheet 17 are magnetically connected. By making the magnetic suction piece 16 and the metal sheet 17 magnetically connected, the inner plate 8 can be more stable inside the side plate 1 of the seedling tray.
[0026] Reference Figure 2 and Figure 5 As shown in this embodiment: a second slide groove 18 is provided on both sides of the first slide groove 2, and a second slide groove 19 is fixedly connected to both sides of the first slide block 5. The surface of the second slide groove 19 is slidably connected to the inside of the second slide groove 18. By allowing the second slide groove 19 to slide inside the second slide groove 18, the movement of the base plate 3 can be made more stable, and the base plate 3 can be prevented from shaking during movement.
[0027] Reference Figure 4 As shown in this embodiment: a second spring 20 is slidably connected to the surface of the movable rod 11. One end of the second spring 20 is fixedly connected to the bottom of the movable rod 11, and the other end of the second spring 20 is fixedly connected to the top end inside the circular groove 9. By setting the second spring 20, the elasticity of the second spring 20 abuts against the movable rod 11, which can limit the movement of the movable rod 11 and prevent the movable rod 11 from moving due to shaking caused by external transportation.
[0028] Reference Figure 4 As shown in this embodiment: both sides of the surface of the movable rod 11 are provided with irregular grooves 21, and both sides of the top of the circular groove 9 are fixedly connected with irregular blocks 22. The surface of the irregular blocks 22 is slidably connected to the inside of the irregular grooves 21. By allowing the irregular blocks 22 to slide inside the irregular grooves 21, the movement of the movable rod 11 can be linearly guided, avoiding displacement of the movable rod 11 when it moves inside the circular groove 9, so that the movable rod 11 drives the limiting block 12 to accurately enter the inside of the square groove 10.
[0029] Working principle: An inner plate 8 is installed inside the side plate 1 of the seedling tray. The inner plate 8 is installed at the top of the support plate 7. The limiting block 12 is lifted, so that one end of the limiting block 12 moves out of the inside of the square groove 10. At this time, the limiting plate 4 releases the limiting of the bottom plate 3. The pulling plate 4 can be pulled, so that the pulling plate 4 moves the bottom plate 3 out of the inside of the side plate 1 of the seedling tray. At the same time, the bottom plate 3 moves the inner plate 8 out of the inside of the side plate 1 of the seedling tray. The seedlings are cultivated on the top of the inner plate 8. After the bottom plate 3 is moved out of the inside of the side plate 1 of the seedling tray, the inner plate 8 can be removed. The inner plate 8, along with the seedlings cultivated on top of it, is removed. After removing the inner plate 8, it can be flexibly connected to a rice transplanter or manually removed. After all the seedlings have been removed, the inner plate 8 is placed back on top of the support plate 7, and the bottom plate 3 is reset, so that one end of the limiting block 12 returns to the inside of the square groove 10, allowing the pull plate 4 and the bottom plate 3 to be repositioned. This design makes the seedling removal process more convenient, avoiding the deformation of the plastic tray or film residue that can easily occur with traditional seedling removal methods such as vibration and knocking. It also increases the number of times the plastic tray can be reused and facilitates cleaning. Cleanliness and maintenance extend equipment life. By setting the first spring 14, when the user releases the movement of the base plate 3, the elasticity of the first spring 14 will drive the base plate 3 to automatically reset, simplifying the operation process. By setting the locking block 15, the movement of the inner plate 8 can be restricted to prevent it from falling off during transportation. By making the magnetic suction piece 16 and the metal piece 17 magnetically connected, the inner plate 8 can be more stable inside the seedling tray side plate 1. By making the second slider 19 slide inside the second slide groove 18, the movement of the base plate 3 can be more stable, preventing the base plate 3 from shaking during movement. By setting the second spring 20, the elasticity of the second spring 20 abuts against the movable rod 11, which can restrict the movement of the movable rod 11 and prevent the movable rod 11 from driving the limiting block 12 to move due to shaking caused by external transportation. By making the irregular block 22 slide inside the irregular groove 21, the movement of the movable rod 11 can have linear guidance, preventing the movable rod 11 from moving inside the circular groove 9, so that the movable rod 11 drives the limiting block 12 to accurately enter the interior of the square groove 10.
[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
