[0003] However, in the current technology, existing vegetable seedlings are generally sprayed with pesticides to prevent and control pests and diseases. Although the effect of preventing and controlling pests and diseases is significant, some pesticide chemical reagents are easily left on the surface of the vegetables, which may affect the food safety of the vegetables themselves. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: In order to prevent and control pests and diseases, insecticides are usually sprayed on vegetable seedlings. Although the effect of preventing and controlling pests and diseases is significant, some chemical reagents used to kill insects are easily left on the surface of the vegetables, which may affect the food safety of the vegetables themselves.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vegetable seedling pest and disease control device, comprising a seedling cultivation platform, wherein a receiving groove is provided at each of the four corner edges of the seedling cultivation platform, and a column is fixed on the surface of the receiving groove. A limiting plate is fixed on the top of the column, and a movable frame is slidably connected to the outer surface of the column by a spring. A mesh cover is fixed at the upper end of the movable frame, and an extension plate is fixed on the front surface of the movable frame. A sliding rod slides through the extension plate, and a pull rod is fixed on one side of the sliding rod. A positioning block is fixed on the front surface of the seedling cultivation platform, and the positioning block and the pull rod are interlocked and engaged.

[0006] In a preferred embodiment, a soft sleeve is fitted onto the surface of the pull rod.

[0007] In a preferred embodiment, several positioning blocks are equidistantly arranged along the surface of the seedling cultivation platform.

[0008] In a preferred embodiment, a locking block is fixedly connected to the lower surface of the movable frame, and the locking block engages with the surface of the seedling cultivation platform.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention provides physical protection for seedlings cultivated on a seedling cultivation platform by placing a net cover over the planting area, effectively preventing pests from approaching and damaging the seedlings. Furthermore, by manually pulling a horizontal lever, the net cover is disconnected from the positioning block, thereby releasing the positioning of the moving frame and net cover on the seedling cultivation platform. The net cover is then pushed upwards by a spring, allowing it to move straight up along the column, thus quickly releasing the physical protection for the seedlings and facilitating daily manual maintenance of the seedlings.

[0016] 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.

[0017] Example 1

[0018] like Figure 1-3As shown, this utility model provides a technical solution: a vegetable seedling pest and disease control device, including a seedling cultivation platform 1. Each of the four corner edges of the seedling cultivation platform 1 has a receiving groove 2. The receiving groove 2 allows the spring 5 compressed by the movable frame 6 to be contained within the mesh cover 7 when it is covering the seedlings on the seedling cultivation platform 1. A column 3 is fixed to the surface of the receiving groove 2, improving the stability of the vertical linear movement of the movable frame 6 and the mesh cover 7. A limiting plate 4 is fixed to the top of the column 3. The 4th setting restricts the movement of the movable frame 6 on the column 3, preventing the movable frame 6 from detaching from the column 3 when it moves upward. A spring 5 is fitted onto the outer surface of the column 3, and the movable frame 6 is slidably connected to it. A mesh cover 7 is fixed to the upper end of the movable frame 6. By covering the planting area of ​​the seedling cultivation platform 1 with the mesh cover 7, the seedlings cultivated on the seedling cultivation platform 1 are physically protected, effectively preventing pests from approaching and damaging them. An extension plate 8 is fixed to the front surface of the movable frame 6, and a sliding plate 8 extends along the extension plate 8. A sliding rod 9 is inserted, and a pull rod 10 is fixed to one side of the sliding rod 9. A positioning block 12 is fixed to the front surface of the seedling cultivation platform 1, and the positioning block 12 is inserted and engaged with the pull rod 10. By manually pulling the pull rod 10 horizontally, the sliding rod 9 moves outward on the extension plate 8, releasing the connection between the pull rod 10 and the positioning block 12. This releases the positioning of the moving frame 6 and the mesh cover 7 on the seedling cultivation platform 1, causing them to be pushed upward by the rebound spring 5, allowing them to move upward in a straight line along the column 3. This quickly releases the physical protection of the seedlings, facilitating daily manual operation. When the maintenance work for seedling cultivation is completed, pull the lever 10 downwards by hand, causing the slide bar 9, extension plate 8, net cover 7, and movable frame 6 to move down along the column 3 and compress the spring 5. When the movable frame 6 moves to be in contact with the surface of the seedling cultivation platform 1, the net cover 7 will provide physical protection for the seedling cultivation area of ​​the seedling cultivation platform 1 again. Then, push the lever 10 inwards by hand to make it re-engage with the positioning block 12, completing the positioning of the movable frame 6 and the net cover 7, so that the net cover 7 can stably protect the seedling cultivation area of ​​the seedling cultivation platform 1.

[0019] Example 2

[0020] like Figure 1-3As shown, a soft sleeve 11 is fitted on the surface of the pull rod 10. The soft sleeve 11 improves the softness of the surface of the pull rod 10. When the user grips the soft sleeve 11 and pulls the pull rod 10, the user's comfort in operating the pull rod 10 is improved. Several positioning blocks 12 are evenly arranged along the surface of the seedling cultivation platform 1. By setting multiple positioning blocks 12, the stability of the pull rod 10 and the positioning blocks 12 when they are engaged can be effectively improved. A locking block 13 is fixedly connected to the lower surface of the movable frame 6, and the locking block 13 is engaged with the surface of the seedling cultivation platform 1. With the setting of the locking block 13, when the net cover 7 covers and protects the seedling area of ​​the seedling cultivation platform 1, the locking block 13 is engaged with the seedling cultivation platform 1, so that the net cover 7 can be more tightly attached to the surface of the seedling cultivation platform 1, providing better and more stable protection for the seedling cultivation platform 1.
