Description

TECHNICAL FIELD

[0001] The utility model belongs to tobacco seedling technique field, concretely relates to a tobacco seedling device. BACKGROUND

[0002] In recent years, tobacco seedling technology gradually marches towards the direction of intensification, standardization and high efficiency. Traditional field seedling methods (such as bare ground sowing) are gradually replaced by modern technology, among which facility seedling technology represented by floating seedling and plug seedling becomes the mainstream. These technologies rely on greenhouse or greenhouse environment, combined with temperature and humidity control, nutrient solution circulation system and automatic equipment, which significantly improves the seedling efficiency.

[0003] Tobacco seedling mainly uses seedling tray as carrier to ensure single seed sowing, high emergence rate, water saving and fertilizer saving, but the seed sowing is a very difficult process. Since tobacco seeds are spherical bodies with a diameter of only about 1mm, artificial twisting is required to put one by one into the seedling hole of the seedling tray, and the sowing speed is slow. Moreover, if not careful, multiple seeds can be easily put into one seedling hole, so that the tobacco seedlings grown from them compete with each other for nutrients, and finally all cannot absorb enough nutrients, with weak growth and cannot meet the transplanting standard. At the same time, the number of seeds required is large, about 3000 to 5000 tobacco plants per mu of land, which corresponds to more than 5000 seedling holes for putting tobacco seeds. For farmers, the workload is very large, and it is very easy to be tired, and it is time-consuming and laborious, so it is urgent to provide farmers with an auxiliary tool for rapid sowing to enable farmers to quickly complete the sowing and seedling work.

Seed cylinder 4; the flat plate 12 has a flat plate hole 121, the upper slide plate 2 has an upper slide plate hole 21, the lower slide plate 3 has a lower slide plate hole 31, and the top plate 13 has a top plate hole 131; the rear plate 15 and the inner side of the front plate 16 have corresponding square grooves 151, the center of the square groove 151 has a gear 24, the two sides of the upper slide plate 2 have upper racks 23, and the two sides of the corresponding lower slide plate 3 have lower racks 32. The upper racks 23 and lower racks 32 mesh with the gear 24 in the middle at the same time, and the upper slide plate 2 and the lower slide plate 3 are staggered from each other in the cavity 101.

[0034] It should be noted that, for reference Figure 1 , Figure 2 , Figure 4As shown, the device has a simple structure. The two side plates 14 are fixed to the side with bolts. When assembling the device, first fix the gear 24 to the middle position of the square groove 151, then place the lower slide plate 3 into the flat plate 12, and then place the upper slide plate 2 above the lower slide plate 3, ensuring that the lower slide plate hole 31 of the lower slide plate 3 is aligned with the flat plate hole 121. When installing the upper slide plate 2 and the lower slide plate 3, both are pushed by translation, so that the upper rack 23 and the lower rack 32 can mesh with the gear 24 in the middle at the same time. Finally, install and fix the side plates 14 to the side. After completing the above work, put the seed cylinder 4 upside down into each top plate hole 131 of the top plate 13. The basic assembly work is then completed.

[0035] In this embodiment, the upper slide plate 2 is provided with a pull tab 22 on its side. In the initial state, the upper slide plate hole 21 is aligned with the top plate hole 131. Pulling the pull tab 22 causes the upper slide plate 2 to move to the left. At the same time, the upper rack 23 moves to the left, driving the gear 24 to rotate. The gear 24 drives the lower rack 32 to move to the right, pushing the lower slide plate 3 to move to the right. The left side of the upper slide plate 2 stops against the side plate 14. At this time, the lower slide plate hole 32 is aligned with the flat plate hole 121.

[0036] In this embodiment, when the upper sliding plate 2 and the lower sliding plate 3 move relative to each other, the upper sliding plate hole 23 and the lower sliding plate hole 32 are aligned and connected in the middle of the path during the movement.

[0037] In this embodiment, the bottom of the seed tube 4 is aligned with the top plate hole 131 and the two holes have the same diameter.

[0038] In this embodiment, a receiving groove 102 is formed between the base plate 11 and the flat plate 12. A seedling tray 5 is provided in the receiving groove 102. The seedling tray 5 is slidably installed in the receiving groove 102. At the same time, the height, width and length of the receiving groove 102 are the same as those of the seedling tray 5. When the seedling tray 5 abuts against the back plate 15, the seedling holes 51 in the seedling tray 5 are located directly below each flat plate hole 121.

[0039] It should be noted that, for reference Figure 3 , Figure 6 , Figure 9 , Figure 11 As shown, the working process of this device is as follows:

[0040] First, place the seedling tray 5 into the receiving groove 102, aligning the seedling hole 51 with the plate hole 121. At this time, the upper sliding plate hole 21 aligns with the top plate hole 131. Tobacco seeds in the seed tube 4 fall from the top plate hole 131 into the upper sliding plate hole 21. Pull the pull tab 22 to move the upper sliding plate 2 to the left. At the same time, the upper rack 23 moves to the left, driving the gear 24 to rotate. The gear 24 drives the lower rack 32 to move to the opposite right, while the lower sliding plate 3 moves to the right. During the movement, the upper sliding plate hole 21 and the lower sliding plate hole 31 align and connect, and tobacco seeds fall from the upper sliding plate hole 21 into the lower sliding plate hole 31. Then continue... Move the upper slide plate 2 against the side plate 14 and stop. The lower slide plate 3 also stops moving. At this time, the upper slide plate hole 21 is aligned with the flat plate hole 121. The tobacco seeds fall from the upper slide plate hole 21 through the flat plate hole 121 into the seedling hole 51, thus completing the seeding work. In this way, the sowing work of the entire seedling tray 5 is completed in one go. Then, take out the seedling tray 5 and push the pull plate 22 back. The right end of the upper slide plate 2 against the side plate 14. The upper slide plate 2 stops moving and returns to the initial position. The upper slide plate hole 21 is aligned with the top plate hole 131 to receive new tobacco seeds. Then put in a new seedling tray 5 and repeat the above operation to fill the seedling tray 5 again. With a simple pull and push, the entire seedling tray 5 can be quickly sown, which is dozens of times faster than manually sowing seeds one by one. Moreover, only one tobacco seed can pass through the hole in the device, which avoids sowing multiple tobacco seeds in one seedling hole 51 during the sowing process. In this way, only one tobacco seedling will grow in each seedling hole 51, which will have sufficient nutrition and grow well. All seedlings can be transplanted into the field, reducing the waste of tobacco seedlings.

[0041] In this embodiment, arc-shaped grooves 141 are provided on both sides of the receiving groove 102 near the opening.

[0042] In this embodiment, a strip groove 111 is linearly formed on the base plate 11, and the distribution area of ​​the strip groove 111 is located directly below the receiving groove 102.

[0043] In this embodiment, a groove 142 is provided on the left side plate 14, and the pull tab 22 extends out from the groove 142.

[0044] It should be noted that, for reference Figure 4 , Figure 5 As shown, the arc-shaped groove 141 facilitates the removal of the seedling tray 5 from the receiving groove 102, and the strip groove 111 facilitates material leakage. When the substrate in the seedling tray 5 is pushed into the receiving groove 102, it may be scraped out. This substrate piles up in the receiving groove 102 and is difficult to clean. The strip groove 111 allows this substrate to leak from the bottom, preventing the side of the seedling tray 5 from not being able to abut against the side plate 14 and the back plate 15. This would also prevent the seedling hole 51 from aligning with the flat hole 121. The strip groove 111 solves these problems.

[0045] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
