Description

Technical Field

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

[0002] There are various methods for tobacco seedling cultivation, including hotbed seedling cultivation, plastic greenhouse seedling cultivation, open field seedling cultivation, and direct-seeding floating seedling cultivation. Among them, direct-seeding floating seedling cultivation involves floating foam trays filled with lightweight seedling substrate on the water surface, sowing seeds in the substrate, and allowing seedlings to take root and grow in the substrate, absorbing water and nutrients from the substrate and waterbed. Compared with traditional seedling cultivation methods, it has advantages such as reducing transplanting labor, saving seedling cultivation land, facilitating tobacco seedling management, promoting the cultivation of strong seedlings, and improving seedling survival rate. However, in the process of tobacco seedling cultivation, it is necessary to strictly control many factors such as seed soaking time, water level, and humidity in the seedling tray, and the waterbed used for seedling cultivation occupies a lot of space.

[0003] Chinese utility model patent with announcement number CN207476368U discloses a tobacco seedling tray. This device can effectively avoid damage caused by manually pulling out seedlings, avoid the waste of resources such as nutrient solution, and can add nutrient solution to some malnourished tobacco seedlings to ensure their survival rate.

[0004] The aforementioned patent employs a method similar to waterbed cultivation. Furthermore, existing technologies offer various applications of waterbed cultivation. For instance, seedling trays containing seeds are placed in a waterbed and moistened for a period, allowing the seeds to absorb some water. The trays are then separated from the water, and after a certain time, the seeds are placed back into the water to slowly absorb more water. This process is repeated, avoiding the strict data control issues inherent in waterbed cultivation and preventing the decay of the seedling medium caused by prolonged soaking. However, this type of cultivation requires different culture solutions for seeds or seedlings at different growth stages, and also necessitates controlling the soaking height to regulate root growth direction. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes the following technical solution:

[0006] A foldable tobacco moist seedling bed includes a rotating frame, a fixed frame, and a seedling tray. The seedling tray has multiple seedling pits, each with a water inlet at the bottom. Both the rotating frame and the fixed frame have foldable support pillars at their bottoms. The rotating frame and the fixed frame are rotatably connected, with the connecting shaft being a rotating shaft. A leak-proof rubber strip is fixedly installed on the rotating frame, allowing it to contact the fixed frame. When in close contact, the rubber strip creates a water reservoir that can be filled with a special nutrient solution for seedling cultivation. A right-hand seedling tray is slidably installed within the fixed frame. The seedling rack includes a right seedling rack that contacts the inner wall of a fixed frame and can contact seedling trays. The right seedling rack is U-shaped and can hold multiple seedling trays. It has multiple slots to restrict the position of the seedling trays. Multiple bottom pressure plates are installed inside the fixed frame, and adjusting screws are rotatably mounted on the bottom pressure plates. The adjusting screws are threadedly connected to the right seedling rack. The adjusting screws and bottom pressure plates are positioned at three locations on the right seedling rack to support it. Rotating the adjusting screws adjusts the distance between the bottom of the right seedling rack and the fixed frame. A left seedling rack is slidably installed inside the rotating frame.

[0007] Furthermore, multiple rotating nuts are rotatably mounted on the rotating frame, and the rotating nuts are symmetrically arranged on the rotating frame. Tightening bolts are rotatably mounted on the outer wall of the fixed frame.

[0008] Furthermore, the rotating nut and the tightening bolt are connected by threads. The tightening bolt and the rotating nut are used to lock the rotating frame and the fixed frame together. The threaded connection between the tightening bolt and the rotating nut further compresses the leak-proof rubber strip, causing the leak-proof rubber strip to deform and fill the gap between the rotating frame and the fixed frame.

[0009] Furthermore, an observation box is fixedly installed on one side of the mounting frame. The observation box is made of glass or plexiglass, and height markings are provided on the outer wall of the observation box.

[0010] Furthermore, a scale is slidably installed inside the observation box, the scale is provided with water level markings, and the scale is also provided with a float. The scale can be used to observe the water level position inside the rotating frame and the fixed frame.

[0011] The advantages of this utility model compared with the prior art are: (1) This device adjusts the distance between the right seedling rack and the bottom of the fixed rack by rotating the adjusting screw, so that the device can cultivate seedlings or seeds of different growth cycles. At the same time, the soaking method of different seedlings or seeds can be controlled by controlling the soaking water level of the seedling tray in the rotating rack and the fixed rack; (2) This device sets an observation box on the side of the fixed rack to observe the height of the adjusting screw in the fixed rack. At the same time, it sets a scale and float in the observation box to observe the water level in the fixed rack, thereby ensuring the precise control of seedlings or seeds during cultivation; (3) This device can be folded and stored by rotating the rotating rack and the fixed rack. At the same time, a rotating shaft is set between the rotating rack and the fixed rack, and the rotating shaft is squeezed by tightening the bolt and rotating nut, so that the device will not leak water during use and achieve the purpose of normal use.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1 to 7 As shown, a foldable tobacco moist seedling bed includes a rotating frame 101, a fixed frame 102, and a seedling tray 103. The seedling tray 103 has multiple seedling pits, each containing seedling substrate. Each seedling pit has a water inlet at its bottom. Both the rotating frame 101 and the fixed frame 102 have foldable support pillars at their bottoms. The rotating frame 101 and the fixed frame 102 are rotatably connected, with a rotating shaft 105 connecting them. The rotating shaft 105 is the rotation center of the rotating frame 101 during rotation, and it is mounted on the fixed frame 102. A leak-proof rubber seal is fixedly installed on the rotating frame 101. The rubber strip 104, which is leak-proof, can contact the fixing frame 102. When the leak-proof rubber strip 104 is in close contact with the fixing frame 102, it is used to make the rotating frame 101 and the fixing frame 102 form a water storage tank. The water storage tank can be filled with seedling-specific nutrient solution. The bottom of the fixing frame 102 is provided with a drain outlet, and a valve is provided at the drain outlet to control the water volume in the fixing frame 102. At the same time, when the nutrient solution is not needed, it can be discharged from the fixing frame 102, so that the nutrient solution can be replaced during tobacco seedling cultivation. It can also achieve dry and wet alternation in the fixing frame 102, and prevent the substrate in the seedling tray 103 from being soaked in water all the time, which would affect the oxygen absorption of the tobacco seedling roots.

[0023] like Figures 1 to 7As shown, a right seedling rack 201 is slidably installed inside the fixed frame 102. The right seedling rack 201 contacts the inner wall of the fixed frame 102 and can contact the seedling trays 103. The right seedling rack 201 is H-shaped and can hold multiple seedling trays 103. The right seedling rack 201 is provided with multiple slots that restrict the position of the seedling trays 103. Multiple bottom pressure plates 204 are installed inside the fixed frame 102. Adjusting screws 202 are rotatably installed on the bottom pressure plates 204. The adjusting screws 202 are threadedly connected to the right seedling rack 201. The adjusting screws 202 and the bottom pressure plates 204 are arranged in the right seedling rack... The three positions of the frame 201 are used to support the right seedling frame 201. After rotating the adjusting screw 202, the gap between the right seedling frame 201 and the fixed frame 102 can be adjusted. The left seedling frame 205 is slidably installed in the rotating frame 101. The left seedling frame 205 is also equipped with multiple adjusting screws 202 and a bottom pressure plate 204 to adjust the gap between the left seedling frame 205 and the bottom of the rotating frame 101. Rotating the multiple adjusting screws 202 can adjust the height of the seedling tray 103 and the right seedling frame 201 in the fixed frame 102. In this way, when planting seedlings or seeds, the depth of immersion of the seedling tray 103 and the seedlings or seeds in water can be controlled, and different heights can be set according to different growth cycles.

[0024] like Figure 1 , Figure 5 , Figure 6 , Figure 8 As shown, a tightening bolt 303 is rotatably mounted on the outer wall of the fixed frame 102, and multiple rotating nuts 304 are rotatably mounted on the rotating frame 101. The rotating nuts 304 are symmetrically arranged on the rotating frame 101, and the rotating nuts 304 are threadedly connected to the tightening bolt 303. The tightening bolt 303 and the rotating nuts 304 are used to lock the rotating frame 101 and the fixed frame 102. The threaded connection between the tightening bolt 303 and the rotating nuts 304 further compresses the leak-proof rubber strip 104, causing the leak-proof rubber strip 104 to deform and fill the gap between the rotating frame 101 and the fixed frame 102 to prevent water leakage. When the device is not in use, the tightening bolt 303 can be rotated to disengage from the rotating nut 304. Then, the rotating frame 101 can be rotated 180 degrees around the rotating shaft 105, and then rotated above the fixed frame 102. At this time, the rotating frame 101 and the fixed frame 102 are locked together. Figure 8 The state shown is the folded state of this device. Figure 8In the displayed state, the folding support on the fixed frame 102 can also be retracted to further reduce space occupation. When in use, the rotating frame 101 is rotated 180 degrees, and then the tightening bolt 303 and the rotating nut 304 are connected by threads. Then, the tightening bolt 303 is rotated continuously to bring the distance between the rotating frame 101 and the fixed frame 102 closer. At this time, the leak-proof rubber strip 104 will be squeezed, thereby filling the gap between the rotating frame 101 and the fixed frame 102. In this way, the rotating frame 101 and the fixed frame 102 will not leak water when storing water.

[0025] like Figure 1 and Figure 2 As shown, an observation box 301 is fixedly installed on one side of the fixed frame 102. The observation box 301 is made of glass or plexiglass. A height scale is provided on the outer wall of the observation box 301. This height scale is used to observe the gap between the bottom of the right seedling rack 201 and the right seedling rack 201. It can also be used to see whether the bottom of the seedling tray 103 will contact the right seedling rack 201. A scale 302 is slidably installed inside the observation box 301. The scale 302 is provided with a water level line and a float. The scale 302 can be used to observe the water level position inside the rotating frame 101 and the fixed frame 102.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
