Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural planting technology, specifically to a device for removing aquatic roots from the bottom of a floating tobacco seedling tray. Background Technology
[0002] During the floating seedling cultivation of tobacco, long aquatic roots often grow from the drainage holes at the bottom of the seedling tray. While these aquatic roots reflect the seedling's growth vitality to some extent, they consume a large amount of nutrients that should be used for the main growth parts of the seedling. More importantly, these aquatic roots cannot be transported to the field with the seedlings during transplanting, thus wasting the nutrients and photosynthetic products consumed during their growth. To reduce nutrient consumption in the nutrient solution and improve the transplant survival rate of tobacco seedlings, these aquatic roots need to be removed periodically.
[0003] Traditionally, the floating trays are manually removed from the nutrient tank, then scraped along the bottom of the trays with bamboo strips before being placed back into the seedling tank. This method is not only time-consuming and labor-intensive, but also extremely inefficient in large seedling factories. Furthermore, because aquatic roots are very fragile and easily broken, they are often not completely removed during the scraping process, potentially damaging the floating trays.
[0004] Therefore, this utility model proposes a submerged floating tobacco seedling tray bottom aquatic root removal device to solve the above problems. Utility Model Content
[0005] To address the aforementioned issues, this invention provides a submerged floating tobacco seedling tray bottom aquatic root removal device, designed to efficiently and accurately remove aquatic roots from the bottom of the floating seedling tray while protecting the structural integrity of the floating seedling tray and nutrient pool, reducing labor costs, and improving seedling efficiency.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a floating tobacco seedling tray bottom aquatic root removal device, including a frame, a collection component and a cutting component installed on the frame, the collection component including a storage box, the storage box being detachably connected to the frame, the side sectional view of the storage box being a trapezoidal structure, and a collection port being opened on the inclined surface of the storage box.
[0007] The cutting assembly includes a cutting blade, which is fixedly connected to a buoyancy plate. The buoyancy plate is fixedly connected to the top of the storage box, and the cutting blade is located above the collection port. A traction assembly is also installed on one side of the storage box.
[0008] The above approach has the following beneficial effects:
[0009] 1. Efficient Removal of Aquatic Roots: This solution utilizes a cutting component design to efficiently and accurately remove aquatic roots from the bottom of the floating seedling tray, avoiding the tedious and time-consuming manual removal. Furthermore, because the cutting blade is located above the collection port, the removed aquatic roots fall directly into the collection box.
[0010] 2. Protection of Floating Seedling Trays and Nutrient Pools: The buoyancy plate design of this device allows it to fit snugly against the bottom of the floating seedling trays without causing damage. Simultaneously, the entire device is suspended in the seedling pool, preventing friction with the waterproof membrane at the bottom and thus protecting the structural integrity of the tobacco seedling nutrient pool.
[0011] 3. Easy to clean and maintain: The detachable connection between the storage box and the frame makes cleaning simple and quick. Operators can easily disassemble the storage box to remove the aquatic roots and other impurities. Furthermore, the design of the traction component makes the device's movement and positioning more flexible and convenient.
[0012] 4. Cost savings and increased efficiency: Compared to traditional manual removal methods, this device can significantly improve the efficiency of removing aquatic roots and reduce labor costs. At the same time, its compact structure and simple operation also reduce the failure rate and maintenance costs during use.
[0013] Furthermore, the traction assembly includes a connecting rod and a drag rope. The connecting rod is fixedly connected to one side of the storage net box, and the drag rope is connected to the end of the connecting rod away from the storage box.
[0014] Beneficial effects: The device allows operators to easily drag it along the bottom of the floating seedling tray using a tow rope, thus removing aquatic roots. The flexibility of the tow rope ensures easy movement of the device in different working environments, improving work efficiency.
[0015] Furthermore, a protective layer is installed at the bottom of the frame to protect the waterproof membrane at the bottom of the tobacco seedling nutrient pool.
[0016] Beneficial effects: The protective layer design protects the waterproof membrane at the bottom of the nutrient tank from friction and damage during device movement. This ensures the structural integrity and normal function of the nutrient tank, prevents leakage of water and nutrients, and is beneficial to the growth of tobacco seedlings.
[0017] Furthermore, the bottom and side walls of the storage box are provided with several drainage holes, which are used to drain the water that enters the storage box, and the drainage holes penetrate the protective layer.
[0018] Beneficial effects: By promptly draining water, the storage box can make fuller use of its internal space, more effectively collecting and storing debris such as cut aquatic roots. This increases the storage capacity of the box and facilitates subsequent cleaning and disposal. The drainage holes also help reduce resistance when the box moves in water. When too much water accumulates inside the box, its overall weight and resistance increase, affecting the device's speed and maneuverability. The drainage holes allow this excess water to drain away promptly, reducing the box's weight and resistance, enabling the device to move more easily on or underwater.
[0019] Furthermore, the cutting blade has a serrated, sharp structure on the side away from the buoyancy plate.
[0020] Beneficial effects: The serrated, sharp structure enhances the cutting ability of the cutting blade, enabling it to remove aquatic roots more effectively. This design improves removal efficiency and reduces resistance and energy consumption during the removal process.
[0021] Furthermore, both the buoyancy plate and the protective layer are made of materials with a density less than water to provide buoyancy.
[0022] Beneficial effects: The material, with a density less than water, allows the buoyancy plate and protective layer to float easily on the water surface, providing the necessary buoyancy for the device. This ensures that the device can maintain close contact with the floating seedling trays without sinking into the nutrient tank. This design improves the stability and efficiency of the device.
[0023] Furthermore, a U-shaped channel is provided at the connection between the buoyancy plate and the cutting blade. One end of the U-shaped channel is the water inlet, and the other end is the water outlet. The length of the channel at the water inlet end is the same as the length of the channel at the water outlet end, and the height of the water outlet is equal to the installation height of the cutting blade.
[0024] Beneficial effects: The U-shaped channel design allows water from the nutrient tank to enter the channel through the inlet and exit at the outlet with a certain speed and pressure. This flushing action helps remove residual aquatic roots and impurities from the cutting blades, preventing them from entangled or clogging them. Simultaneously, the outlet height is equal to the installation height of the cutting blades, ensuring that the flushing water directly acts on the blades, improving the cleaning effect. This design extends the service life of the cutting blades and improves the reliability and durability of the device.
[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] The following detailed description illustrates the specific implementation method:
[0033] Example 1:
[0034] As attached Figure 1As shown: A submerged floating tobacco seedling tray bottom aquatic root removal device. The frame is equipped with a collection component and a cutting component. The collection component includes a storage box 1, which is detachably connected to the frame via straps for easy cleaning and replacement. The side sectional view of the storage box 1 shows a trapezoidal structure. A collection opening 2 is provided on the inclined surface of the storage box 1, allowing the cut aquatic roots to fall smoothly into the box. This allows the storage box 1 to utilize gravity to allow the cut aquatic roots to naturally slide to the bottom, preventing accumulation and blockage. Several drainage holes 8 are provided on the bottom and side walls of the storage box 1 to drain water entering the box, preventing moisture accumulation from affecting the collection effect.
[0035] The cutting assembly includes a cutting blade 3, to which a buoyancy plate 4 is bonded. The side of the cutting blade 3 away from the buoyancy plate 4 has a serrated, sharp structure, enabling it to cut aquatic roots more effectively and improving cutting efficiency. The buoyancy plate 4 is fixedly connected to the top of the storage box 1, and the cutting blade 3 is located above the collection port 2. A protective layer 7 is installed at the bottom of the frame, which protects the waterproof membrane at the bottom of the tobacco seedling nutrient pond. Both the buoyancy plate 4 and the protective layer 7 are made of materials with a density less than water, such as foam plastic, to provide buoyancy, allowing it to float in the seedling pond and maintain close contact with the floating seedling tray above the tobacco seedling nutrient pond.
[0036] A traction assembly is also installed on one side of the storage box 1. The traction assembly includes a connecting rod 5 and a drag rope 6. The connecting rod 5 is fixedly connected to one side of the storage box, and the drag rope 6 is connected to the end of the connecting rod 5 away from the storage box 1. With the drag rope 6, the operator can easily drag the entire device to move it at the bottom of the floating seedling tray to remove aquatic roots.
[0037] The specific implementation process is as follows: During the floating seedling cultivation of tobacco, long aquatic roots often grow in the small water holes at the bottom of the seedling trays in the tobacco seedling nutrient pool. Their growth consumes a large amount of nutrients but is not conducive to the survival of transplanted tobacco seedlings; therefore, they need to be removed from time to time to reduce the consumption of nutrients in the nutrient solution. Assemble the device completely, ensuring that all components are firmly connected. Check whether the storage box 1 is dry and clean, and whether the cutting blade 3 is sharp.
[0038] Place the device in the nutrient tank, ensuring it floats on the surface. Use the tow rope 6 to move the device below the floating seedling tray, allowing it to make close contact with the tray using its buoyancy. The operator holds the tow rope 6 and slowly drags the device along the bottom of the floating seedling tray. The cutting blade 3 effectively cuts off the aquatic roots during this sliding motion and transfers them to the collection box 1 through the collection port 2.
[0039] After cleaning, remove the device from the nutrient tank, disassemble the storage box 1, and clean out the aquatic roots. Inspect the wear of the cutting blade 3 and replace it if necessary. Regularly inspect all components of the device to ensure they are in good condition. Clean the storage box 1 and the protective layer 7, and keep them dry and clean.
[0040] In summary, the floating seedling trays do not need to be removed from the nutrient tank, greatly saving time and effort. The device operates while suspended in the seedling tank, preventing damage to the waterproof membrane at the bottom. The storage box 1 is detachably connected to the frame for easy cleaning and replacement. The device has a simple structure, is easy to operate and maintain, and is suitable for tobacco seedling nutrient tanks of various sizes.
[0041] Example 2:
[0042] As attached Figure 2 As shown, the difference from Embodiment 1 is that a U-shaped channel 9 is provided at the connection between the buoyancy plate 4 and the cutting blade 3. One end of the U-shaped channel 9 is a water inlet and the other end is a water outlet. The length of the channel at the water inlet end is the same as the length of the channel at the water outlet end, and the height of the water outlet is equal to the installation height of the cutting blade 3.
[0043] The specific implementation process is as follows: The operator holds the towing rope 6 and slowly drags the device along the bottom of the floating seedling tray. During the sliding process, the cutting blade 3 effectively cuts off the aquatic roots. At the same time, liquid in the nutrient tank enters through the inlet of the U-shaped channel 9.
[0044] When the liquid reaches the outlet through the U-shaped channel 9, it rushes out at a certain speed and pressure, directly impacting the cutting blade 3. This flushing action effectively removes the aquatic roots attached to the cutting blade 3, preventing them from tangling on the blade and thus maintaining the sharpness and working efficiency of the cutting blade 3.
[0045] Obviously, the above embodiments are merely examples for clarity and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
