Description

Technical Field

[0001] This utility model relates to a tobacco seedling drying tray device, belonging to the field of tobacco floating seedling technology. Background Technology

[0002] In the field of floating seedling cultivation for flue-cured tobacco, drying the seedling trays is a key technical step. Its purpose is to separate the floating seedling trays from the water surface to reduce substrate moisture and promote healthy growth of tobacco seedlings.

[0003] Existing literature (CN217905618U) discloses a pulley-driven lifting drying tray device for seedling greenhouses, comprising: a seedling greenhouse, including seedling pools, columns, and crossbeams, wherein the columns are arranged around the seedling pools, the crossbeams are fixed to the top of the columns, and one crossbeam is provided on each side of each seedling pool; a lifting unit, including a drive mechanism, double pulleys, a pull rope, and a support plate, wherein two sets of double pulleys are provided on the crossbeams corresponding to each side of each seedling pool, one end of the pull rope is connected to the drive mechanism, and the other end of the pull rope passes through the double pulleys and is connected to the support plate. The applicant has found through actual production that the existing drying tray device still suffers from high investment costs for modification, inconvenience in use, and a tendency to cause nutrient solution spillage and waste. Utility Model Content

[0004] Based on the above, this utility model provides a tobacco seedling drying tray device to overcome the shortcomings of the prior art.

[0005] The technical solution of this utility model is: a tobacco seedling drying tray device, comprising:

[0006] The tray unit includes a support frame, a support rod, and tray ropes. The support frame and the support rod are respectively arranged on two opposite sides of the seedling pool. Multiple tray ropes are spaced apart between the support frame and the support rod, and the tray ropes hang down into the seedling pool.

[0007] The push-pull unit includes a drive mechanism connected to the force rod. The drive mechanism can drive the force rod to move back and forth, so that the tray rope moves between the liquid surface and the liquid surface in the seedling pool.

[0008] In one example, one end of the pallet rope is fixed to the support frame by a fixing bolt.

[0009] In one example, the push-pull unit further includes fixed pulleys and a pull rope. The fixed pulleys are spaced apart on the side of the seedling pool. One end of the pull rope is connected to the force rod, and the other end of the pull rope is connected to the drive mechanism after passing through the fixed pulleys.

[0010] In one example, the driving mechanism is a lifting winch, and the connection point between the tray rope and the support frame, the height of the fixed pulley, and the height of the lifting winch are all the same, all higher than the predetermined height of the seedling pond.

[0011] The beneficial effects of this utility model are as follows: This utility model, through a support frame, a support rod, a tray rope, and a drive mechanism, forms a tobacco seedling drying tray device, changing the existing floating seedling greenhouse method to a tidal seedling method. The device lifts the seedling trays, simulating natural tidal phenomena to cultivate high-quality tobacco seedlings. When it is necessary for the seedling trays to leave the water surface, the device uses a lifting winch to tighten the tray rope, causing the trays to rise and leave the water. The device has a simple structure and is easy to operate. The tray rope also reduces the waste of nutrient solution. Attached Figure Description

[0017] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] Please see Figure 1This embodiment discloses a tobacco seedling drying tray device, comprising a tray unit 1 and a push-pull unit 2. The tray unit 1 includes a support frame 11, a support rod 12, and tray ropes 13. The support frame 11 and the support rod 12 are respectively arranged on two opposite sides of the seedling pool 3. Multiple tray ropes 13 are spaced apart between the support frame 11 (fixed to the support frame 11 by fixing bolts) and the support rods 12. The tray ropes 13 hang down in the seedling pool 3, and two tray ropes 13 form a group, with the seedling tray placed above them. The push-pull unit 2 includes a drive mechanism 21, which is connected to the support rod 12. The drive mechanism 21 can drive the support rod 12 to move back and forth, causing the tray ropes 13 to move between below and above the liquid surface in the seedling pool 3, thereby causing the seedling tray to move between floating on the liquid surface and detached from the liquid surface.

[0019] For ease of operation, the push-pull unit 2 also includes fixed pulleys 22 and pull ropes 23. Multiple fixed pulleys 22 are spaced apart and installed along the side of the seedling pool 3. One end of the pull rope 23 is connected to the force rod 12, and the other end of the pull rope 23 is connected to the drive mechanism 21 after passing through the fixed pulleys 22. The drive mechanism 21 is a lifting winch. The connection point between the pallet rope 13 and the support frame 11, the height of the fixed pulleys 22, and the height of the lifting winch are all the same, all 350 mm above the seedling pool. In this embodiment, the lifting winch is an 800-pound one-way self-locking winch, the pallet rope 13 and the pull rope 23 are 4 mm diameter steel wire ropes, and the force rod 12 is a DN20 diameter galvanized steel pipe.

[0020] Installation and use of the above-mentioned tobacco seedling drying trays:

[0021] First, use fixing bolts to secure the tray rope 13 to the support frame 11 on the left aisle of the seedling pond 3. The connection point between the fixing bolts and the tray rope 13 should be 50 mm higher than the embankment of the seedling pond 3. Fix the fixed pulley 22 to the embankment, with the height of the fixed pulley 22 parallel to the connection point of the tray rope 13 and the lifting winch. Fix the lifting winch on the right aisle of the seedling pond 3, 50 mm higher than the right embankment of the seedling pond 3. Shake the lifting winch, and use the force rod 12 to make the multiple tray ropes 13 parallel at the same height. After the tobacco seedling cooling tray device is installed and debugged, use the lifting winch to loosen the tray rope 13 and lower it to the bottom of the seedling pond. When it is necessary for the seedling tray to leave the water surface, tighten the tray rope 13 by using the lifting winch to raise the seedling tray and lift it out of the water surface.

[0022] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
