Description

Technical Field

[0001] This utility model belongs to the technical field of flue-cured tobacco planting equipment, specifically relating to a drip-proof device for flue-cured tobacco seedling sheds. Background Technology

[0002] When planting flue-cured tobacco, plastic greenhouses are required for seedling cultivation. During this process, due to a significant drop in nighttime temperature, water vapor condenses on the greenhouse roof film. Water droplets then drip due to gravity, and if these droplets happen to fall directly into the seedling area, they can negatively impact the seedlings. Current technology involves erecting a shade over the seedling area, but this shade is difficult to retract, affecting daytime sunlight and hindering seedling growth. Therefore, a drip-proof device for flue-cured tobacco seedling greenhouses is needed to solve these technical problems. Summary of the Invention

[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides a drip-proof device for tobacco seedling sheds, comprising a support frame. The support frame includes two tripods, the bases of which are fixed to the ground via uprights. A horizontal rod is fixedly connected between the tops of the two tripods. A horizontal guide rod is fixed between the two uprights on the same side of the two tripods. Multiple sliding rings are fitted onto the guide rod. A membrane is mounted on the horizontal rod, with one end of the membrane being fixed and the other end being movable. The fixed end is fixedly connected to the corresponding tripod. Both sides of the membrane are fixedly connected to the sliding rings on the corresponding guide rods. The length of the membrane between adjacent sliding rings is the same, and the even distribution of the sliding rings on the membrane allows for smoother movement. By pulling the movable end of the membrane, it can be unfolded to cover the tobacco seedlings. Water dripping from the seedling shed falls onto the membrane and slides down, preventing it from landing on the seedlings. During the day, the movable end of the membrane moves towards the fixed end, causing the membrane to gather together and preventing insufficient light.

[0004] Preferably, the horizontal rod is a screw, with both ends rotatably connected to corresponding tripods via bearings. One end of the screw passes through the tripod and is connected to a forward / reverse motor. A slider is threaded onto the screw, and the middle portion of the movable end of the membrane fabric is fixedly connected to the slider. A horizontal limiting rod is fixed above the screw, and a limiting groove is provided on the lower surface of the limiting rod. A limiting block slides within the limiting groove, and the limiting block is connected to the top of the slider. By rotating the forward and reverse motor, the slider can pull the movable end of the membrane fabric along the screw, realizing the unfolding and gathering of the membrane fabric, reducing manual operation and improving the degree of automation.

[0005] Preferably, the guide rod is fitted with a U-shaped water collection trough, which is parallel to the guide rod, and the guide rod is positioned inside the water collection trough. The water collection trough can collect the water that slides down, preventing liquid splashing.

[0006] Preferably, one end of the water collection tank is sealed, and the other end is connected to a liquid guide pipe, with the liquid outlet of the liquid guide pipe fitted with a liquid collection bucket. The liquid collection bucket can effectively utilize the collected water, saving resources.

[0007] This utility model also includes other components that enable the anti-drip device for tobacco seedling sheds to function properly, such as the control components for the forward and reverse motors, which are all conventional technologies in the field. Furthermore, devices or components not specified in this utility model, such as membrane cloth and screws, all employ conventional technologies and equipment in the field.

[0008] Working principle: At night, pulling the movable end of the film sheet unfolds it to cover the tobacco seedlings. Water dripping from the seedling shed falls onto the film sheet, which, with the help of the horizontal and guide rods, forms two inclined surfaces. The water slides down these inclined surfaces without landing on the seedlings. During the day, pulling the movable end of the film sheet towards the fixed end causes it to close up, preventing insufficient light.

[0009] The beneficial effects of this invention are: at night, the film can catch the water dripping from the seedling shed and guide the water to avoid adverse effects on the tobacco seedlings; during the day, the film can be folded up to one side without affecting the light, which is conducive to the growth of the tobacco seedlings.

[0013] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0014] Example 1 like Figure 1-3 As shown, this utility model provides a drip-proof device for a tobacco seedling shed, including a support frame. The support frame includes two tripods 2, the bottoms of which are fixed to the ground via columns 1. A horizontal rod 16 is fixedly connected between the tops of the two tripods 2. A horizontal guide rod 14 is fixed between the two columns 1 on the same side of the two tripods 2. Multiple sliding rings 15 are fitted on the guide rod 14. A membrane 4 is laid on the horizontal rod 16. One end of the membrane 4 is fixed, and the other end is movable. The fixed end is fixedly connected to the corresponding tripod 2. The two sides of the membrane 4 are fixedly connected to the sliding rings 15 on the corresponding guide rods 14. The length of the membrane 4 between adjacent sliding rings 15 is the same. The even distribution of the sliding rings 15 on the membrane 4 makes the membrane 4 move more smoothly. By pulling the movable end of the membrane 4, the membrane 4 can be unfolded to cover the tobacco seedlings 9. Water dripping from the seedling shed falls onto the membrane 4 and slides down the membrane 4, preventing it from falling onto the tobacco seedlings 9. During the day, the movable end of the membrane 4 moves toward the fixed end, and the membrane 4 gathers together to avoid insufficient light.

[0015] The guide rod 14 is fitted with a U-shaped water collection tank 6, which is parallel to the guide rod 14 and is located within the water collection tank 6. The water collection tank 6 collects any spilled water, preventing liquid splashing.

[0016] One end of the water collection tank 6 is sealed, and the other end is connected to a liquid guide pipe 7. The outlet end of the liquid guide pipe 7 is fitted with a liquid collection bucket 8. The liquid collection bucket 8 can effectively utilize the collected water, saving resources.

[0017] Example 2 like Figure 4-6As shown, the difference between this embodiment and Embodiment 1 is that the horizontal rod 16 is a screw 10. Both ends of the screw 10 are rotatably connected to connecting plates 12 via bearings. The connecting plates 12 are fixedly connected to the corresponding tripod 2. One end of the screw 10 passes through the tripod 2 and is connected to a forward / reverse motor 5. A slider 13 is threaded onto the screw 10. The middle part of the movable end of the membrane fabric 4 is fixedly connected to the slider 13. A horizontal limiting rod 3 is fixed above the screw 10. The lower surface of the limiting rod 3 has a limiting groove, and a limiting block 11 slides within the limiting groove. The limiting block 11 is connected to the top of the slider 13. By rotating the forward / reverse motor 5, the slider 13 can pull the movable end of the membrane fabric 4 along the screw 10, realizing the unfolding and gathering of the membrane fabric 4, reducing manual operation and improving automation. In this embodiment, the membrane cloth can be set as two pieces, which are respectively placed on both sides of the screw. Each piece of membrane cloth forms a separate inclined surface, so as to avoid the membrane cloth being laid on the screw when the whole membrane cloth is used, and the screw will cause wear to the membrane cloth when the membrane cloth is pulled.

[0018] The forward and reverse motors and membrane cloth (which can be made of plastic film) in the above embodiments are all existing technologies. This application does not make any improvements to them, but only utilizes their existing functions. For their specific structure and principle, please refer to the product manual or existing technical information, which are all existing technologies.

[0019] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments.
