Description

Technical Field

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

[0002] Tobacco is a plant of the Solanaceae family, mainly used to produce tobacco products such as cigarettes, cigars, chewing tobacco, and snuff. Tobacco seedling devices are specialized equipment or systems used to cultivate seedlings from tobacco seeds. They can provide a suitable growth environment, ensure healthy and uniform growth of seedlings, and improve transplant survival rate.

[0003] A multi-layer seedling raising device is described in the existing patent document with authorization announcement number CN221598877U. The described solution involves setting two U-shaped plates on the frame, and setting two side plates, two bottom plates and two blades between the two U-shaped plates. When the user cultivates bean sprouts through the frame and seedling tray, the bean sprouts can be directly cut and harvested by the blades after they mature without removing the seedling tray, which is convenient and quick.

[0004] The aforementioned technology has the problem of not being able to retrieve and place seedling trays at heights. Operators generally have a height limit, and beyond a certain point, it becomes inconvenient to retrieve and place the trays. In this case, operators need to climb ladders or shelves to retrieve and place the seedling trays, which can easily lead to accidents such as falls, falls, and crushing injuries. If the seedling trays accidentally fall while operating at heights, they may damage the seedlings or injure the staff. In addition, the aforementioned technology also has the problem of not being able to water the seedlings at each layer. The seedlings at the top layer may suffer from water shortage or drought because they cannot receive water in time. Furthermore, if the seedling roots cannot absorb enough water, it will lead to the roots being unable to absorb nutrients from the soil normally, resulting in slow growth or cessation of growth.

By inserting the tray-retrieving fork 504 into the hollow block 507, and then placing the support rods 506 at the bottom of the seedling trays 400 into the limiting grooves 505, the seedling trays 400 can be stacked.

[0031] In one embodiment, such as Figure 2 As shown, the rotating assembly includes a support plate 601, which is disposed on one end of the sliding sleeve 300. A first motor 602 is provided at the bottom of the support plate 601. The output end of the first motor 602 passes through the support plate 601 and is provided with a second rotating gear 603. The second rotating gear 603 meshes with the first rotating gear 502. By starting the first motor 602, it drives the second rotating gear 603 to rotate, thereby driving the first rotating gear 502 to rotate.

[0032] In one embodiment, such as Figure 1 and Figure 2As shown, the lifting assembly includes a rack 701, which is mounted on one side of the support column 200.

[0038] The above embodiments disclose a multi-layer tobacco seedling raising device. In this device, the fork 504 is inserted into the hollow block 507. Then, the second motor 703 is started, causing the worm gear 704 to rotate, which in turn rotates the worm wheel 705 and the rotating rod. This, in turn, drives the third rotating gear 706 and the rack 701 to mesh, thereby raising and lowering the support box 702 and the sliding sleeve 300. Next, the third motor 902 is started, causing the threaded rod 903 to rotate, which in turn moves the slider 901 and the support column 200, thus moving the seedling tray 400 above the bottom seedling tray 400. Then, the second motor 703 is started again, placing the support rod 506 at the bottom of the seedling tray 400 on a limit... Inside the slot 505, the seedling trays 400 are stacked. When watering the seedlings inside the seedling trays 400 is required, the third motor 902 can be started again to move the support column 200 away from the seedling trays 400. Then, the first motor 602 is started to drive the second rotating gear 603 to rotate, which in turn drives the first rotating gear 502 to rotate, thereby moving the water outlet pipe 802 closer to the seedling trays 400. Then, the water pump 804 is started to deliver water to the hose 805, which then reaches the water outlet pipe 802. The water is then discharged through several spray heads 803. Then, the third motor 902 is started again to move the spray heads 803 above the seedling trays 400 and spray water.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
