DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] The present utility model provides a new type of flue-cured tobacco seedling tray transportation device, as Figures 1-4 shown, which includes a bottom plate 1. A side baffle 2 is installed on the top side of the bottom plate 1. A pressing assembly 3 is installed on the top of the side baffle 2. A locking shaft 21 is installed on the side of the pressing assembly 3. Threaded ends 23 are provided at both ends of the locking shaft 21. Through holes are provided at the top of the side baffle 2. The threaded ends 23 pass through the through holes and are locked and fixed by locking nuts 24.
[0023] In this embodiment, a pull rod 4 is installed at one end of the bottom plate 1, and a handle 41 is installed at the outer end of the pull rod 4, which is convenient for manually pulling the bottom plate 1 to move.
[0024] Specifically, a plurality of universal wheels 11 are installed at the bottom of the bottom plate 1, which is convenient for the flexible movement of the device.
[0025] Furthermore, the bottom end of the side baffle 2 is rotatably connected to the side of the bottom plate 1 through a rotating shaft, which is convenient for the side baffle 2 to flip. When loading and unloading, unlock the locking shaft 21 and then open the side baffle 2 to the horizontal position.
[0026] Furthermore, the pressing assembly 3 includes an upper plate 31 and a lower plate 32. The middle of the locking shaft 21 is rotatably connected to both ends of the upper plate 31 through a bearing 22. A threaded hole 311 is provided in the middle of the upper plate 31. A threaded rod 33 is threadedly connected in the threaded hole 311. A turntable 331 is installed at the top end of the threaded rod 33, and a pressing plate 332 is installed at the bottom end of the threaded rod 33.
[0027] Furthermore, guide posts 321 are installed on both sides of the top of the lower plate 32. Guide sleeves 322 are inserted at the top of the guide posts 321. The bottom ends of the guide posts 321 are welded and fixed to the lower plate 32, and the top ends of the guide sleeves 322 are welded and fixed to the bottom of the upper plate 31.
[0028] Furthermore, anti-slip lines are provided on the surface of the side baffle 2, which has a good anti-slip effect and avoids the sliding of the side of the seedling tray.
[0029] Furthermore, the pull rod 4 is of a V-shaped structure, and both ends of the pull rod 4 are hinged to one end of the bottom plate 1, which is convenient for adjusting the position of the pull rod 4, convenient for manually pulling the pull rod 4, and thus driving the bottom plate 1 for transportation.
[0030] It should be noted that when folding is required, first disassemble the pressing assembly 3 and place it on the bottom plate 1. Then, flip and fold the side baffle 2 on the side of the bottom plate 1, and then flip and fold the pull rod 4 on the bottom plate 1, so as to realize the folding and storage of the whole device.
[0031] When the novel tobacco seedling raising tray transporting device of the utility model is in use, first place the tobacco seedling raising tray on the bottom plate 1 to ensure that the position of the seedling raising tray is centered and stable. Then, flip the side baffle 2 to the vertical state through the hinge so that it closely adheres to the side of the seedling raising tray, playing a role in limiting and fixing. At this time, the anti-slip pattern on the surface of the side baffle 2 can effectively prevent the seedling raising tray from slipping sideways during transportation.
[0032] Next, by rotating the locking nuts 24 at both ends of the locking shaft 21, the threaded end 23 of the locking shaft 21 is tightly locked in the through hole of the side baffle 2, thereby fixing the side baffle 2 in the vertical state and ensuring the stability of the seedling raising tray during transportation.
[0033] Subsequently, by rotating the turntable 331 on the pressing assembly 3, the threaded rod 33 moves downward in the threaded hole 311, and then drives the pressing plate 332 to move downward until the pressing plate 332 closely adheres to the top of the seedling raising tray, firmly fixing it on the bottom plate 1. During this process, the plug-in structure of the guide post 321 and the guide sleeve 322 plays a good guiding and stabilizing role, ensuring that the pressing assembly 3 does not shift when moving up and down.
[0034] Finally, by pulling the handle 41 at the outer end of the pull rod 4, the bottom plate 1 can be easily pushed or pulled to move. Since universal wheels 11 are installed at the bottom of the bottom plate 1, the device can be flexibly moved in different directions, facilitating the transportation of the seedling raising tray to the designated position. During transportation, since the seedling raising tray is firmly fixed on the bottom plate 1, it can effectively prevent the seeds from shifting or being damaged due to vibration or extrusion.
[0035] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art of this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection claimed by the utility model is defined by the appended claims and their equivalents.
