Description

Technical Field

[0001] This utility model relates to the field of tobacco seedling technology, specifically a tobacco planting seedling device. Background Technology

[0002] Tobacco is an annual herbaceous plant belonging to the genus Nicotiana in the family Solanaceae. It originated in the Americas and is now widely cultivated in countries such as China, Brazil, and India. Yunnan, Guizhou, and Henan provinces in China are the main producing areas. Its core use is in the production of tobacco products such as cigarettes and cigars, and it is also used in medicinal research. Cultivation involves several stages, including seedling raising, transplanting, field management, harvesting, and curing. Tobacco seedling raising is a crucial step in tobacco production, directly affecting the yield and quality of subsequent tobacco leaves. Tobacco seedling raising technology has evolved from traditional direct seeding to a modern seedling raising system that primarily uses floating seedling raising supplemented by other efficient methods. The core objective is to cultivate "strong, uniform, and disease-free seedlings."

[0003] In floating seedling cultivation, foam seed trays filled with lightweight substrate are floated on the surface of water containing nutrient solution. Tobacco seeds are sown in the substrate and, after taking root, absorb nutrients from the substrate and the water bed. However, in actual seedling cultivation, preparation work such as digging seedling beds and constructing greenhouses is required. The excavation depth of the seedling beds must be kept uniform, which hinders the efficient and rapid construction of the seedling platform. Furthermore, the fixed area of ​​the excavated seedling beds lacks flexibility and is detrimental to efficient seedling cultivation. Therefore, we propose a tobacco planting seedling machine. Utility Model Content

[0004] The purpose of this utility model is to provide a tobacco seedling raising device. By using water troughs instead of traditional seedling ponds, it can achieve uniform depth throughout the plant. The number of water troughs can be selected and spliced ​​together according to the seedling quantity to flexibly adjust the seedling area. The water troughs are quickly fixed in the soil by inserting the side tubes, and the support rods can be efficiently fixed and a greenhouse can be built using the tubes. It is easy to disassemble and can be reused, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tobacco planting seedling device, comprising a water trough and a support rod. Three equidistant horizontal plates are welded to both sides of the water trough. A sleeve is welded and fixed to the surface of the horizontal plate and passes through the middle of the horizontal plate. A tube that passes through the horizontal plate is slidably inserted into the sleeve. The bottom of the tube is sealed and the top is open. A first through-hole is opened on the side of the sleeve, and a second through-hole is opened on the upper side of the tube. The support rod is U-shaped and has through-holes at both ends. When the two ends of the support rod are inserted into the tubes on both sides and the height of the tubes is lowered, the through-holes are aligned with the first and second through-holes, and the plug passes through the first through-hole, the second through-hole, and the through-hole to pass through the sleeve, the tube, and the support rod.

[0006] By adopting the above technical solution, a corresponding number of water tanks are selected and spliced ​​together according to the area required for seedling cultivation, and the water tanks are locked by inserting tubes into the soil. At the same time, the greenhouse is built by fixing the support rods with the inserting tubes, which can facilitate the floating seedling cultivation of tobacco seedlings.

[0007] Optionally, the lower sides of the water tank are respectively provided with through holes and connecting pipes that communicate with the inside of the water tank. When adjacent water tanks are spliced, the connecting pipes are inserted into the through holes to achieve the purpose of communication.

[0008] By adopting the above technical solution, when the water tanks are used together, they can be connected through the socket and connecting pipe, making it convenient to add water and fertilizer in a unified manner.

[0009] Optionally, two through-holes and two connecting tubes are provided. A rubber ring is fixedly fitted to the inner ring of the through-hole, and the rubber ring touches the outer surface of the connecting tube when the connecting tube is inserted into the through-hole.

[0010] By adopting the above technical solution, the two connecting channels ensure better flow between adjacent water tanks.

[0011] Optionally, the side of the insertion tube is provided with a vertical limiting strip, which can be vertically slidably placed in a limiting groove provided inside the sleeve.

[0012] By adopting the above technical solution, the insertion tube is prevented from rotating inside the sleeve, and after the insertion tube is lowered, the first insertion port is easily aligned with the second insertion port.

[0013] Optionally, a limiting plate is welded and fixed to the top of the insertion tube, and the middle of the limiting plate is connected to the inside of the insertion tube.

[0014] By adopting the above technical solution, the insertion tube is prevented from sliding down when the water tank is lifted and moved.

[0015] Optionally, a crossbar is fixed laterally on the side of the limiting plate, and the end of the crossbar is connected to the limiting plate by welding.

[0016] By adopting the above technical solution, when it is necessary to pull the inserted tube out of the soil later, it can be easily pulled out with the help of a crossbar.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application uses water troughs instead of traditional seedling ponds, which can achieve uniform depth throughout. The appropriate number of water troughs can be selected and spliced ​​together according to the seedling quantity to flexibly adjust the seedling area. The water troughs are quickly fixed in the soil by inserting the side tubes, and the support poles can be efficiently fixed and a greenhouse can be built with the help of the tubes. It is easy to disassemble and can be reused.

[0019] 2. The technical solution of this application provides connecting pipes and through holes on both sides of the water tank. After splicing, the connecting pipes are inserted into the through holes to connect the adjacent water tanks, which facilitates the synchronous management of water and fertilizer addition in the later stage.

[0020] 3. The technical solution of this application provides a limiting strip on the side of the insertion tube that can be slidably placed in the limiting groove inside the sleeve, which can prevent the insertion tube from rotating inside the sleeve, making it easier to align the first and second insertion ports later. The crossbar also makes it easier to pull out the insertion tube later. Attached Figure Description

[0027] Please see Figure 1-4 This utility model provides a technical solution: a tobacco planting seedling device, including a water trough 1 and a support rod 2. Multiple water troughs 1 are provided and are the same size. When in use, multiple water troughs 1 can be spliced ​​together. The specific number used depends on the amount of seedlings to be cultivated. When splicing, the ends of the water troughs 1 are connected.

[0028] To facilitate unified management after assembly, two through-holes 11 and two connecting pipes 12 are respectively installed on the lower sides of each water tank 1, communicating with the inside of the water tank 1. When assembling, the connecting pipes 12 are inserted into the through-holes 11 to achieve communication. A rubber ring 111 is also fixed to the inner ring of the through-hole 11. When the connecting pipe 12 is inserted into the through-hole 11, the rubber ring 111 touches the outer surface of the connecting pipe 12 to keep the connection sealed and prevent water leakage. During use, the connecting pipes 12 or through-holes 11 at both ends of the water tank 1 need to be sealed with rubber sleeves or rubber plugs. Water containing nutrient solution is located in the water tank 1. Subsequently, foam seedling trays can be floated in the water tank 1 to achieve floating seedling cultivation. Since the water tanks 1 are kept in a connected state, water or fertilizer can be added to any water tank 1 for convenient management.

[0029] Three equidistant horizontal plates 3 are welded to both sides of the water trough 1. A sleeve 31 is welded and fixed to the surface of each horizontal plate 3 and passes through the middle of the horizontal plate 3. A tube 4 that passes through the horizontal plate 3 is slidably inserted into the sleeve 31. The bottom of the tube 4 is sealed and the top of the tube 4 is welded and fixed with a limiting plate 43. The middle of the limiting plate 43 is connected to the inside of the tube 4. When the water trough 1 is assembled on the leveled soil surface, the tube 4 is struck with a hammer to insert the bottom of the tube 4 into the soil, which can achieve the purpose of fixing the water trough 1. Then, the two ends of the U-shaped support rod 2 can be inserted into the tubes 4 on both sides to achieve quick fixation of the support rod. Then, the support rod 2 can be used to build a greenhouse, which is more convenient to use.

[0030] In addition, a first through-hole 311 is provided on the side of the sleeve 31, and a second through-hole 41 is provided on the upper side of the insertion tube 4. At the same time, through-holes 11 are provided at both ends of the support rod 2. When both ends of the support rod are inserted into the insertion tube 4, both ends of the support rod 2 are inserted into the insertion tube 4. The first through-hole 311 on the surface of the sleeve 31 is aligned with the second through-hole 41 on the surface of the insertion tube 4 and the through-hole 11 at the end of the support rod 2. Then, the bolt 5 passes through the first through-hole 311, the second through-hole 41 and the through-hole 11 through the sleeve 31, the insertion tube 4 and the support rod 2, thereby locking the insertion tube 4 and the sleeve 31 and locking both ends of the support rod 2 in the insertion tube, thereby locking the support rod 2.

[0031] Due to the arrangement of the first insertion port 311 and the second insertion port 41, when the insertion tube 4 is knocked downwards into the soil, the insertion tube 4 is prone to rotation, causing the first insertion port 311 and the second insertion port 41 to become misaligned. Therefore, a vertical limiting strip 42 is provided on the side of the insertion tube 4. The limiting strip 42 can slide vertically in the limiting groove 312 provided inside the sleeve 31. The insertion tube 4 will not rotate when it is raised or lowered inside the sleeve 31, so that the first insertion port 311 and the second insertion port 41 can be easily aligned after the insertion tube 4 is lowered.

[0032] Additionally, a horizontal bar 431 is fixed to the side of the limiting plate 43. The end of the horizontal bar 431 is connected to the limiting plate 43 by welding. When it is necessary to pull the insertion tube 4 out of the soil and release the lock on the water tank 1, the horizontal bar 431 can be held directly by hand or the horizontal bar 431 can be clamped with pliers and lifted up to facilitate the extraction of the insertion tube 4 from the soil.

[0033] In use, place the water trough 1 on a leveled soil surface. When multiple water troughs 1 are used together, connect the ends of the water troughs 1 together, and insert the two connecting pipes 12 of adjacent water troughs 1 into the two through holes 11 of the water troughs 1 connected to them, so that the water troughs 1 are in a connected state. Then, use a hammer to tap the top of the insertion pipe 4, which will push the bottom of the insertion pipe 4 into the soil to fix the water trough 1 in position, and align the second insertion hole 41 with the first insertion hole 311. Then, insert both ends of the support rod 2 into the insertion pipes 4 on both sides, aligning the through holes at both ends of the support rod 2 with the first insertion hole 311 and the second insertion hole 41. Finally, insert the plug 5 through the sleeve. The first insertion port 311 of the sleeve 31, the second insertion port 41 of the insertion tube 4, and the through port at the end of the support rod 2 are used to connect and lock the insertion tube 4 with the sleeve 31 and the support rod 2, thereby fixing the support rod 2. Finally, a film is covered on the support rod 2 to form a greenhouse structure, and the connecting pipe 12 or through port 11 located at both ends of the water tank 1 is sealed with a rubber sleeve or rubber plug. Finally, culture medium can be added to the water tank 1, and the foam seedlings planted with tobacco seeds are placed in the water tank 1 so that they float on the surface of the culture medium. Sealing both ends of the greenhouse can achieve the purpose of seedling cultivation, and ventilation and other operations can be performed when needed. During the seedling cultivation process, water or some fertilizer can be added to the water tank 1. After the seedlings are grown, remove the rubber sleeve of the connecting pipe 12 or the rubber plug of the opening 11 on one side of the end water tank 1 to drain the water. Then, remove the film, pull out the plug 5 to remove the support rod 2, and pull out the insertion tube 4 to separate and remove the water tank 1. When pulling out the insertion tube 4, you can use the crossbar 431 to help pull it out. Hold the crossbar 431 and lift it up or use pliers to clamp the crossbar 431 and lift it up to pull out the insertion tube 4.
