Description

Technical Field

[0001] The utility model relates to the technical field of seedling greenhouses, in particular to a flue-cured tobacco seedling greenhouse with an anti-drip device. Background Art

[0002] Compared with traditional seedling raising methods, greenhouse seedling raising has lower labor input and shorter seedling raising time, which is labor-saving, time-saving and low-cost, and is conducive to commercial seedling raising operations. However, during the greenhouse seedling raising process, due to the sharp drop in temperature at night, the water vapor in the greenhouse condenses on the greenhouse roof film. Because the top space of the greenhouse is large, even if the roof adopts a drip-free film, the path for water droplets to slide to the two sides of the shed wall is far away. During the process of water droplets sliding to the two sides of the shed wall, the adhesion force cannot withstand the gravity of the water droplets, which will still cause water droplets to drip. If it happens to drip into the seedling raising pool, it will have an adverse effect on the tobacco seedlings: on the one hand, the dripping water droplets will splash out the sown seeds, affecting the emergence of the seedlings, and at the same time splash the substrate, covering the germinating seedlings, affecting the normal growth of the seedlings; on the other hand, the dripping water droplets often cause excessive humidity in the dripping place, and the green algae breed seriously, making the entire seedling bed a patch of green algae, affecting the normal growth of the tobacco seedlings. If the prevention and control are not timely, it will cause devastating losses, so it is very necessary to carry out drip prevention treatment for the greenhouse.

[0003] In the related technology, reference can be made to the Chinese patent with the announcement number CN217241711U, which specifically discloses a drip-proof tobacco seedling greenhouse device. When the drip-proof tobacco seedling greenhouse device is in use, the water droplets on the inner wall of the roof will fall on the drainage plate at the lower end of the connecting rod. Through the inclination of the drainage plate itself, the water droplets on the upper end of the drainage plate will fall into the two first water guide grooves, and the water in the first water guide grooves will be transported to the water storage tank through the water pipe. The drainage plate is made of transparent acrylic sheet material, which does not affect the light intensity in the greenhouse. When there are too many water droplets on the inner wall of the roof that affect the light, the staff will drive the blowing component to work, and the water droplets at the center of the roof will be blown to both sides through the blowing component. , so that the water droplets fall quickly on the drainage plate, and by driving the vibration component to work, the flow rate of the water droplets on the upper end of the drainage plate is increased to actively remove water. The water droplets on the inner wall of the drainage plate are transported to the water storage tank through the second guide groove and the water guide pipe, further increasing the anti-drip effect of the greenhouse. When it is necessary to increase the flow speed of the water droplets on the upper end of the drainage plate, the staff drives the vibration motor on the upper end of the mounting rod to work, and the vibration motor drives the mounting rod and the drainage plate to vibrate slightly, thereby increasing the movement speed of the water droplets on the upper end of the drainage plate.

[0004] When active water removal is required, the staff drives the fan in the operating box to transport the gas in the greenhouse to the air blowing pipe through the air inlet, and then transports the gas to the three jet parts through the air blowing pipe, and then transports the gas to the two jet heads through the jet pipe in the jet part, and sprays the gas to both sides through the two jet heads to achieve the purpose of active water removal.

[0005] However, the above-mentioned drip-proof tobacco seedling greenhouse device has shortcomings when used: although the water droplets can be drained and collected, which is not easy to cause adverse effects on the tobacco seedlings, the installation position of the drainage plate is relatively fixed. Since the tobacco seedlings need to carry out photosynthesis during their growth, the drainage plate blocks the light at this time, affecting the photosynthesis of the tobacco seedlings, which is not conducive to the growth and use of the tobacco seedlings.

[0029] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-2 As shown, a flue-cured tobacco seedling shed with an anti-drip device comprises a base 1, a greenhouse frame 2 is installed on the base 1, and a double-slope ceiling 3 is installed on the top of the greenhouse frame 2; connecting seats 6 are installed at the inner top corners of the longitudinal front and rear ends of the main ridge of the ceiling 3, a fixing plate 7 is installed between the lower ends of the two connecting seats 6, and a positioning plate 9 is installed at the bottom of the fixing plate 7 through a connecting guide rod 8, and a movable plate 10 is sleeved on the connecting guide rod 8, and the movable plate 10 is located between the fixing plate 7 and the positioning plate 9, and the positioning plate 9 is provided between the fixing plate 7 and the positioning plate 9. A threaded rod 11 is threadedly connected to the middle part of the plate 9, and the top end of the threaded rod 11 is rotatably abutted against the movable plate 10; drainage racks 12 are rotatably connected to the lateral sides of the fixed plate 7, and angle adjustment plates 16 are rotatably connected to the two sides of the movable plate 10, and the other side of the angle adjustment plate 16 is rotatably connected to the middle and upper part of the drainage rack 12; a drainage groove 13 is provided on the side of the upper end of the drainage rack 12 away from the fixed plate 7, and the drainage groove 13 is connected to a downward drainage pipe 14, and the lower end of the drainage pipe 14 is connected to the water collecting box 5.

[0031] Through the above device, the threaded rod 11 is used to control the up and down movement of the movable plate 10 to adjust the opening angle of the drainage rack 12, so that the drainage rack 12 can be easily unfolded and stored. When the drainage rack 12 is unfolded, it is convenient to drain and collect water droplets, preventing water droplets from dripping and splashing the sown seeds, affecting the emergence of seedlings, and breeding green algae, affecting the normal growth of tobacco seedlings; when the drainage rack 12 is stored, it avoids the drainage rack 12 blocking the sunlight and affecting the photosynthesis of the tobacco seedlings.

[0032] Specifically, the side of the drainage frame 12 connected to the fixing plate 7 is higher than the side of the drainage frame 12 where the drainage groove 13 is provided.

[0033] For example, Figure 2 As shown, the drainage rack is inclined, and the end connected to the fixed plate is higher than the end with the drainage groove. When collecting water droplets, it is convenient for the water droplets to flow to the drainage groove, ensuring that the water droplets can be effectively collected.

[0034] Specifically, an external threaded tube 15 is provided at the upper end of the drainage tube 14 , and the drainage tube 14 is threadedly connected to the interior of the drainage frame 12 through the external threaded tube 15 and communicated with the drainage groove 13 .

[0035] For example, Figure 3-4 As shown, the drainage tube 14 is threadedly connected to the inside of the drainage rack 12 through the external threaded tube 15 set at the top, and is connected to the drainage groove 13. The water droplets collected on the drainage rack 12 enter the drainage tube 14 along the drainage groove 13 and are then stored in the water collection box.

[0036] Specifically, the inner bottom surface of the drainage groove 13 is an inclined structure, and the position connected with the drainage pipe 14 is the lowest point.

[0037] For example, Figure 3 As shown, the inner bottom surface of the drainage groove 13 is sloped, and one end connected to the drainage pipe 14 is at the lowest point of the bottom surface of the drainage groove 13, so that water can automatically flow into the drainage pipe 14 under the action of gravity, which is convenient for drainage.

[0038] Specifically, a planting area 4 is arranged inside the base 1 .

[0039] Specifically, the water collecting box 5 is arranged on both lateral sides of the base 1 and is located directly below the drainage groove 13 .

[0040] Specifically, a through hole adapted to the connecting guide rod 8 is provided at the installation position of the movable plate 10 and the connecting guide rod 8, and the connecting guide rod 8 is inserted into the through hole.

[0041] For example, Figure 2 As shown, the connecting guide rod 8 passes through the matching through hole on the movable plate 10, ensuring that the movable plate 10 moves in the same direction as the connecting guide rod 8 when moving up and down, and at the same time keeping the movable plate 10 stable and not shaking left and right.

[0042] Specifically, the ceiling 3 and the greenhouse frame 2 are detachably installed.

[0043] For example, Figure 2 As shown, the vertical cross-section of the ceiling 3 is a triangular structure, which ensures the stability of the structure; the ceiling 3 and the greenhouse frame 2 are detachably installed, which is convenient for the later maintenance and replacement of the ceiling.

[0044] Specifically, a threaded hole adapted to the threaded rod 11 is opened inside the positioning plate 9, and the threaded rod 11 is threadedly connected in the threaded hole.

[0045] Specifically, a handle is provided at the bottom end of the threaded rod 11 .

[0046] For example, Figure 2 As shown, the threaded rod 11 passes through the threaded hole opened on the positioning plate 9 and rotates to abut against the movable plate 10. When in use, the handle set at the bottom end of the threaded rod 11 is rotated to generate a force through the thread and the positioning plate 9, driving the movable plate 10 to move upward or downward, thereby completing the deployment and storage of the drainage rack; the handle is disc-shaped, and uses the principle of leverage to make it easier and more labor-saving to rotate the threaded rod.

[0047] The working principle of this utility model:

[0048] When the tobacco seedlings do not need to carry out photosynthesis, the threaded rod 11 drives the movable plate 10 to move upward, and the movable plate 10 drives the angle adjustment plate 16 to adjust the angle of the drainage frame 12. When the angle of the drainage frame 12 is adjusted to the maximum position, when water droplets are generated on the inner side of the ceiling 3, the water droplets will fall into the drainage groove 13 through the drainage frame 12, and then the water droplets inside the drainage groove 13 will be drained to the inside of the water collection box 5 through the drainage pipe 14 for storage.

[0049] When the tobacco seedlings need to carry out photosynthesis, the threaded rod 11 drives the movable plate 10 to move downward, and the movable plate 10 drives the angle adjustment plate 16 to adjust the angle of the drainage rack 12. When the angle of the drainage rack 12 is adjusted to the minimum, the drainage rack 12 is stored to prevent the drainage rack 12 from blocking sunlight and affecting the photosynthesis of the tobacco seedlings.
