Description

Technical Field

[0001] This utility model relates to the field of seedling tray technology, and in particular to a seedling tray that is convenient for injecting nutrient substrate. Background Technology

[0002] The seedling tray is an indispensable component of the rice transplanter. Its main function is to realize the seedling raising process of rice seedlings. The seedling tray is made of polyvinyl chloride as raw material and is processed by special process formula to form a vacuum-formed product. It has the characteristics of being lightweight, easy to transport, easy to store and keep, and low cost of use.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: most existing seedling trays are of an integrated structure, and their seedling holes are usually in a closed or semi-closed state. When injecting nutrient substrate, not only is the efficiency low, but it is also difficult to ensure the uniform distribution of nutrient substrate in each seedling hole, which can easily lead to some seedlings growing poorly due to insufficient or excessive nutrients. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of inconvenient operation and uneven distribution of nutrient substrate when injecting seedling trays. Therefore, we propose a seedling tray that is convenient for injecting nutrient substrate.

[0005] To achieve the above objectives, this application adopts the following technical solution: a seedling tray for convenient injection of nutrient substrate, comprising a seedling tray: the seedling tray consists of two layers, the upper layer being a seedling layer and the lower layer being a liquid storage layer, the liquid storage layer and the seedling layer being rotatably connected by a rotating shaft, the seedling layer being provided with multiple seedling holes, each of the multiple seedling holes being provided with a through hole, the liquid storage layer and the seedling layer being connected through the through hole, handles being provided on both sides of the front end of the seedling layer, a connecting block being fixed to the front end of the seedling layer, a connecting shell being fixed to the front end of the liquid storage layer, and an opening and closing mechanism for opening and closing the liquid storage layer and the seedling layer being provided inside the connecting shell.

[0006] Preferably, the opening and closing mechanism includes a handle threaded to the side wall of the connecting shell, a limit block fixed at one end of the handle inside the connecting shell, two movable plates sliding inside the connecting shell, the two movable plates being located on both sides of the limit block, a locking block fixed at the top of the movable plates, and a locking groove matching the locking block at both ends of the connecting block.

[0007] Preferably, springs are fixed on both sides inside the connecting shell, and the other end of the spring is fixed to the moving plate.

[0008] Preferably, the limiting block is elliptical in shape.

[0009] Preferably, limit rods are fixed on both sides inside the connecting shell, and the surface of the movable plate is provided with limit holes that match the limit rods.

[0010] Preferably, the surface of the long shaft end of the grip is covered with an anti-slip pad.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, the opening and closing mechanism allows the liquid storage layer and the seedling raising layer to open or close quickly, making the operation simple and efficient. Furthermore, the through holes allow the nutrient substrate to slowly permeate into each seedling raising hole of the seedling raising layer, ensuring that each seedling raising hole can absorb the nutrient substrate evenly.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. 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.

[0020] Reference Figures 1-4As shown, this utility model provides a technical solution: a seedling tray for convenient injection of nutrient substrate, comprising a seedling tray: the seedling tray consists of upper and lower layers, the upper layer being a seedling layer 2 and the lower layer being a liquid storage layer 1, the liquid storage layer 1 and the seedling layer 2 being rotatably connected by a rotating shaft, the seedling layer 2 being provided with multiple seedling holes 3, each seedling hole 3 having a through hole 5, the liquid storage layer 1 and the seedling layer 2 being connected through the through holes 5, handles 4 being provided on both sides of the front end of the seedling layer 2, a connecting block 6 being fixed to the front end of the seedling layer 2, and a connecting shell 7 being fixed to the front end of the liquid storage layer 1, the connecting shell 7 having an internal structure for connecting the liquid storage layer 1 and the seedling layer 2. The opening and closing mechanism for the seedling layer 2 includes a handle 8 threaded to the side wall of the connecting shell 7. A limit block 9 is fixed to one end of the handle 8 inside the connecting shell 7. Two movable plates 10 slide inside the connecting shell 7, located on either side of the limit block 9. A locking block 11 is fixed to the top of each movable plate 10. Both ends of the connecting block 6 have slots 12 that match the locking blocks 11. Springs 13 are fixed to both sides inside the connecting shell 7, with the other end of each spring 13 fixed to the movable plate 10. This opening and closing mechanism allows for rapid opening and closing between the liquid storage layer 1 and the seedling layer 2. The system opens and closes quickly, is easy to operate, and is highly efficient. When it is necessary to inject nutrient substrate into the storage layer 1, rotate the handle 8. The handle 8 drives the limiting block 9 to rotate, at which point the limiting block 9 moves away from the two moving plates 10. The moving plates 10 are no longer squeezed by the limiting block 9 and are pushed by the rebound force of the spring 13, causing the locking block 11 to move out of the locking slot 12. Then, rotate the seedling layer 2 through the handle 4 to open the gap between the seedling layer 2 and the storage layer 1, at which point the nutrient substrate can be injected into the storage layer 1. After the nutrient substrate is injected, pull the handle 4 to close the gap between the seedling layer 2 and the storage layer 1. When the tray is closed, the handle 8 is rotated again to drive the limiting block 9 to rotate, which compresses the moving plate 10. The spring 13 begins to contract, and the moving plate 10 is compressed, causing the locking block 11 to engage in the slot 12, thus limiting the seedling layer 2. This ensures that the seedling layer 2 can be stably connected to the liquid storage layer 1, preventing the seedling layer 2 from shaking during transportation. This improves the stability of the seedling tray during use. Furthermore, the through holes 5 allow the nutrient substrate to slowly permeate into each seedling hole 3 of the seedling layer 2, ensuring that each seedling hole 3 can absorb the nutrient substrate evenly.

[0021] Reference Figure 4 As shown in this embodiment, the limiting block 9 is elliptical in shape. The elliptical design allows the limiting block 9 to gradually press the two moving plates 10 during rotation, thereby making the movement of the moving plates 10 more stable and avoiding jamming between the moving plates 10 and the limiting block 9.

[0022] Reference Figure 4As shown in this embodiment: Limiting rods 14 are fixed on both sides inside the connecting shell 7, and limiting holes 15 matching the limiting rods 14 are opened on the surface of the moving plate 10. By setting the limiting rods 14 and the limiting holes 15, the movement trajectory of the moving plate 10 can be limited, avoiding the moving plate 10 from deviating during the movement, and further improving the stability of the opening and closing mechanism.

[0023] Reference Figure 4 As shown in this embodiment, an anti-slip pad 16 is fitted on the surface of the long shaft end of the grip 8. The anti-slip pad 16 increases the firmness between the grip 8 and the connecting shell 7, preventing loosening and affecting the fixing effect.

[0024] Working Principle: The user can quickly open or close the liquid storage layer 1 and the seedling layer 2 using the opening and closing mechanism. The operation is simple and efficient. When it is necessary to inject nutrient substrate into the liquid storage layer 1, rotate the handle 8. The handle 8 drives the limiting block 9 to rotate, at which point the limiting block 9 moves away from the two moving plates 10. The moving plates 10 are no longer squeezed by the limiting block 9 and are pushed by the rebound force of the spring 13, causing the locking block 11 to move out of the slot 12. Then, rotate the seedling layer 2 using the handle 4 to open the connection between the seedling layer 2 and the liquid storage layer 1, allowing nutrient substrate to be injected into the liquid storage layer 1. After the nutrient substrate is injected, pull the handle 4 to close the connection between the seedling layer 2 and the liquid storage layer 1. Then, rotate the handle 8 again to rotate the limiting block 9, squeezing the moving plate 10. The spring 13 begins to contract, and the moving plate 10, under pressure, causes the locking block 11 to engage in the slot 12, limiting the seedling layer 2 and allowing the seedling to grow. The seedling layer 2 can be stably connected to the liquid storage layer 1, avoiding shaking during transportation and improving the stability of the seedling tray during use. The through-holes 5 allow the nutrient substrate to slowly permeate into each seedling hole 3 of the seedling layer 2, ensuring that each seedling hole 3 absorbs the nutrient substrate evenly. The elliptical design allows the limiting block 9 to gradually compress the two moving plates 10 during rotation, making the movement of the moving plates 10 smoother and preventing jamming between the moving plates 10 and the limiting block 9. The limiting rod 14 and limiting hole 15 limit the movement trajectory of the moving plates 10, preventing deviation during movement and further improving the stability of the opening and closing mechanism. The anti-slip pad 16 increases the firmness between the handle 8 and the connecting shell 7, preventing loosening and ensuring a secure fit.

[0025] 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.
