Description

Technical Field

[0001] This utility model relates to the technical field of tobacco seedling auxiliary equipment, specifically an adjustable tobacco seedling tray support. Background Technology

[0002] A tobacco seedling tray support is an agricultural device specifically designed to support and secure tobacco seedling trays, aiming to provide a stable, efficient, and optimized environment for the growth of tobacco seedlings. It is typically made of corrosion-resistant materials and features adjustable height, multi-layer design, and good ventilation and lighting conditions, making it suitable for tobacco seedling greenhouses or home seedling cultivation settings.

[0003] A search revealed existing technology, specifically Chinese patent application number CN202222426599.8, which discloses a double haploid tobacco seedling cultivation rack. This utility model includes: a seedling component comprising a seedling rack body, a base, a seedling tray, a guide groove, and a slider; and a sowing mechanism comprising a placement plate, a guide rail, a sliding plate, a flexible scraper, through holes, a baffle, and a limiting plate. The base is uniformly fixed to the outer wall of the seedling rack body, and the seedling tray is slidably connected to the upper surface of the base. This utility model places the double haploid tobacco seeds to be cultivated on the placement plate, then moves the sliding plate using the flexible scraper to flatten the seeds and push them into the through holes. Moving the baffle releases the restriction on the double haploid tobacco seeds, allowing the seeds in the through holes to fall into the seedling tray under gravity, thus completing the placement of the double haploid tobacco seeds. This eliminates the need for manual placement, improving work efficiency and saving manpower.

[0004] However, the device also has the following drawbacks:

[0005] Because the tobacco seedling tray support is multi-layered, the lower seedling trays may not receive as much light and ventilation as the upper ones, which could affect the uniformity of seedling growth in the lower layers. Furthermore, during the tobacco seedling cultivation process, aphids and moths are more likely to come into contact with the seedlings, thus affecting their healthy growth. Utility Model Content

[0032] An adjustable tobacco seedling tray support includes a base 1, a first support 2 installed on the top of the base 1, a second support 4 above the first support 2, and a third support 5 above the second support 4. The first support 2, the second support 4, and the third support 5 are arranged in a U-shape.

[0033] The top periphery of the first bracket 2 and the second bracket 4 is provided with adjustment components for adjusting the height of the second bracket 4 and the third bracket 5. The adjustment components include a telescopic seat 3, a telescopic support rod 301, a fixing hole 302 and a locking pin 303. The telescopic seat 3 is fixedly installed around the top periphery of the first bracket 2 and the second bracket 4, and the top of the telescopic seat 3 is provided with a telescopic support rod 301. The bottom of the telescopic seat 3 is slidably connected to the inside of the telescopic seat 3. The front top of the telescopic seat 3 is provided with a locking pin 303. Several sets of fixing holes 302 are sequentially opened on the front of the telescopic support rod 301. One end of the locking pin 303 that penetrates into the inside of the telescopic seat 3 is engaged in the fixing hole 302.

[0034] This utility model uses components such as telescopic seat 3, telescopic support rod 301, fixing hole 302 and locking pin 303 to facilitate height adjustment of the second support 4 and the third support 5, so as to prevent the impact on the tobacco seedlings in the lower layer, thereby improving the light and ventilation effect of the tobacco seedlings in the first support 2 and the second support 4.

[0035] Furthermore, when the height of the second bracket 4 and the third bracket 5 needs to be adjusted, firstly, the support column is removed by hand and moved outward from the telescopic seat 3 to disengage it; then, the second bracket 4 and the third bracket 5 are moved upward in sequence so that the telescopic support rod 301 on its bottom moves upward from the inside of the telescopic seat 3 for adjustment. After adjusting to a suitable height, the locking pin is removed and inserted into the inside of the telescopic seat 3 to lock and fix it in place with the fixing hole 302; thereby improving the effect of light and ventilation on the first bracket 2 and the second bracket 4.

[0036] The inner center of the first support 2, the second support 4 and the third support 5 is provided with a bracket 8, which facilitates the support and placement of the seedling tray 11; the top center of the bracket 8 is provided with a placement groove 10, and the seedling tray 11 for tobacco seedlings is placed inside the placement groove 10; several sets of drainage outlets are provided at the bottom of the placement groove 10, which correspond to the bottom of the seedling tray 11; a water collection shell 12 is provided below the bottom of the bracket 8 for collecting drainage from the seedling tray 11.

[0037] The back ends of the first support 2, the second support 4, and the third support 5 are equipped with insect-repelling components for tobacco seedling control. The insect-repelling components include a mounting frame 16, slots 17, and sticky insect boards 18. The mounting frame 16 is located at both ends of the back of the first, second, and third supports 5. Slots 17 are opened on the inner side of the mounting frame 16, and sticky insect boards 18 for trapping aphids and thrips are inserted into the slots 17. Four sets of symmetrical slots 20 are respectively opened at both ends of the back of the first, second, and third supports 5. Locking blocks 19 are engaged inside the slots 20 and are fixedly installed at both ends of the back of the mounting frame 16.

[0038] This utility model uses a combination of components such as a mounting frame 16, a slot 17, an insect-sticking board 18, a locking block 19, and a locking groove 20 to facilitate the placement of tobacco seedling trays 11 on the support for cultivation, thereby preventing insect infestation and improving the growth of tobacco seedlings. It also makes it convenient to replace the insect-sticking board 18 regularly. In addition, the insect-sticking board 18 is available in yellow and blue colors to facilitate the prevention of aphids and thrips.

[0039] Furthermore, by taking the sticky insect board 18 and unfolding it, and then sliding it into the slot 17 provided inside the mounting frame 16, it can be positioned and suspended. Then, the sticky side of the sticky insect board 18 is facing the seedling tray 11, which facilitates the insect prevention treatment of tobacco seedlings and also makes it convenient to replace it regularly.

[0040] Meanwhile, the set-in locking blocks 19 and locking slots 20 facilitate the removal of the mounting bracket 16 from the tobacco seedling tray 11 support.

A first sliding plate 7 is slidably connected inside the first sliding groove 6, and the first sliding plate 7 is fixedly installed on both sides of the bracket 8. A pull plate 9 for hand grip is installed on the front of the bracket 8.

[0042] By holding the pull plate 9 with your hand, you can move the bracket 8 outward so that the first slide plate 7 on both sides of the bracket 8 can be moved out of the first slide groove 6, making it easier to take out the seedling tray 11 inside, and also making it easier to replace the seedling tray 11.

[0043] The first bracket 2, the second bracket 4, and the third bracket 5 have second sliding grooves 14 on their lower inner sides, and second sliding plates 13 are slidably connected inside the second sliding grooves 14. The second sliding plates 13 are fixedly installed on both sides of the water collecting shell 12, and drain outlets 15 are opened at both ends of the inner bottom of the water collecting shell 12. The drain outlets 15 are sealed with plungers inside.
