Abstract
Description
Technical Field
[0001] This utility model relates to the field of seedling tray technology, and in particular to a rice seedling tray. Background Technology
[0002] In the development of modern agriculture, rice cultivation has always occupied an important position. In the early days, traditional rice seedling raising mostly adopted the field-based method, which directly divided areas in the field for seedling raising. However, this method has many drawbacks. On the one hand, the field environment is difficult to control precisely, as temperature, humidity, and light conditions fluctuate significantly with changes in natural weather. In cold seasons, seedlings are susceptible to frost damage, affecting germination rate and healthy seedling growth; while in hot and rainy seasons, they may face problems such as waterlogging, frequent pests and diseases, leading to poor seedling growth or even death. On the other hand, the uneven distribution of seedlings in field-based raising makes it difficult to achieve standardized and large-scale production, which is not conducive to subsequent mechanized transplanting operations. Manual transplanting is labor-intensive and inefficient, and cannot meet the needs of large-scale, high-efficiency production in modern agriculture.
[0003] The existing rice seedling trays have a relatively simple and open internal space. The seedlings are planted in a large space, making it difficult to provide an independent growth area for each seedling. As a result, it is difficult to accurately control the growth environment of each seedling during the seedling raising process. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a rice seedling tray.
[0005] This utility model is achieved by the following technical solution: a rice seedling tray, including a main body, a lifting mechanism is provided on the top of the main body, and a protective mechanism is provided on one side of the lifting mechanism;
[0006] The main structure includes a body, the top of which has a groove, a shelf is fixedly connected in the groove, a grid is fixedly connected to the top of the shelf, a partition is provided on one side of the grid, and the partition is fixedly connected to the shelf.
[0007] As a further improvement to the above solution, a handle is fixedly connected to the top of the body, and the handles are symmetrically distributed along the body, with two handles in total.
[0008] Through the above technical solution, the main structure, the storage board, and the grid provide an independent and regular space for rice seedling cultivation. Each grid can cultivate a single seedling, which helps to precisely control the growth environment of the seedlings and ensure that each seedling receives relatively consistent nutrients, water, and light conditions, thereby cultivating more uniform and robust seedlings. The partition further separates adjacent grids, avoiding interference between the seedling substrates in different grids and also enhancing the structural stability to a certain extent.
[0009] As a further improvement to the above solution, the lifting mechanism includes a pad plate, a pad block is fixedly connected to the top of the pad plate, a sliding groove is opened on the top of the pad block, a limiting shaft is fixedly connected in the sliding groove, a sliding block is sleeved on the surface of the limiting shaft, a first fixed shaft is fixedly connected to the top of the sliding block, a connecting plate is sleeved on the surface of the first fixed shaft, and a second fixed shaft is sleeved on the side of the connecting plate away from the first fixed shaft.
[0010] As a further improvement to the above solution, the pad and the pad block are symmetrically distributed through a connecting plate, and there are two of each type of pad and pad block.
[0011] Through the above technical solution, the lifting mechanism allows the seedling tray to adjust its height according to actual needs, driving the sliding block to slide on the limit shaft, thereby achieving the adjustment of the overall height of the seedling tray. By raising the seedling tray, the seedlings can receive more sunlight. When it needs to be used in conjunction with specific irrigation or fertilization equipment, it can also be adjusted to a suitable height, improving the adaptability and controllability of the seedling raising process.
[0012] As a further improvement to the above solution, the protective mechanism includes a first lifting block, a second lifting block is sleeved inside the first lifting block, the second lifting block extends to the top of the first lifting block, and both the first lifting block and the second lifting block are fixedly connected to the pad block.
[0013] As a further improvement to the above solution, a first protective plate is fixedly connected to one side of the first lifting block, and a second protective plate is sleeved on the top of the first protective plate.
[0014] Through the above technical solution, the protective mechanism ensures a tight connection between the protective mechanism and the lifting mechanism, and allows for synchronous movement as the height of the lifting mechanism is adjusted. The first protective plate on one side of the first lifting block and the second protective plate fitted on the top form a multi-layered protection. The first protective plate prevents the sides of the seedling tray from being hit and scratched by external objects, protecting the main structure of the seedling tray. The second protective plate protects the top of the seedling tray, preventing foreign objects from falling into the holes and contaminating the seedling substrate or damaging the seedlings, thus providing a reliable protective barrier for the growth of the seedlings.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention provides an independent and orderly space for rice seedling cultivation through its main structure, a storage plate, and a grid of holes. Each hole can cultivate one seedling individually, facilitating precise control of the seedling's growth environment and ensuring that each seedling receives relatively consistent nutrients, water, and light conditions, resulting in more uniform and robust seedlings. The partition further separates adjacent holes, preventing interference between the seedling substrates in different holes and enhancing structural stability to some extent. A lifting mechanism allows the seedling tray to be adjusted in height according to actual needs, moving a sliding block along a limit shaft to adjust the overall height of the tray. Raising the tray allows the seedlings to... To obtain more sunlight, and when used in conjunction with specific irrigation or fertilization equipment, the height can be adjusted to a suitable level, improving the adaptability and controllability of the seedling raising process. Through the set protective mechanism, it is ensured that the protective mechanism and the lifting mechanism are closely integrated, and can move synchronously with the height adjustment of the lifting mechanism. The first protective plate on one side of the first lifting block and the second protective plate fitted on the top form a multi-layer protection. The first protective plate can prevent the side of the seedling tray from being hit and scratched by external objects, protecting the main structure of the seedling tray. The second protective plate plays a protective role on the top of the seedling tray, preventing foreign objects from falling into the holes and contaminating the seedling substrate or damaging the seedlings, providing a reliable protective barrier for the growth of seedlings.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0024] Example:
[0025] Please combine Figure 1-4 A rice seedling tray according to this embodiment includes a main body 1, a lifting mechanism 2 is provided on the top of the main body 1, and a protective mechanism 3 is provided on one side of the lifting mechanism 2.
[0026] The main body 1 includes a body 101. A groove is provided on the top of the body 101. A shelf 102 is fixedly connected in the groove. A grid 103 is fixedly connected on the top of the shelf 102. A partition is provided on one side of the grid 103. The partition is fixedly connected to the shelf 102.
[0027] A handle 104 is fixedly connected to the top of the body 101. The handles 104 are symmetrically distributed through the body 101, and there are two handles 104.
[0028] The lifting mechanism 2 includes a pad plate, a pad block 201 is fixedly connected to the top of the pad plate, a sliding groove is provided on the top of the pad block 201, a limiting shaft 202 is fixedly connected in the sliding groove, a sliding block 203 is sleeved on the surface of the limiting shaft 202, a first fixed shaft is fixedly connected to the top of the sliding block 203, a connecting plate 204 is sleeved on the surface of the first fixed shaft, and a second fixed shaft is sleeved on the side of the connecting plate 204 away from the first fixed shaft.
[0029] The pads and blocks 201 are symmetrically distributed through the connecting plate 204, and there are two of each pad and block 201.
[0030] The protective mechanism 3 includes a first lifting block 301, a second lifting block 302 is sleeved inside the first lifting block 301, the second lifting block 302 extends to the top of the first lifting block 301, and both the first lifting block 301 and the second lifting block 302 are fixedly connected to the pad block 201.
[0031] A first protective plate 303 is fixedly connected to one side of the first lifting block 301, and a second protective plate 304 is sleeved on the top of the first protective plate 303.
[0032] The implementation principle of this utility model is as follows: When the lifting mechanism 2 is activated, the operator manually operates the connecting plate 204 to rotate it around the first fixed axis and the second fixed axis. As the connecting plate 204 rotates, the sliding block 203 slides along the slide groove on the limiting shaft 202, and the overall height of the seedling tray gradually changes until the required height position is reached. During this process, the first lifting block 301 and the second lifting block 302 of the protective mechanism 3 will rise or fall synchronously with the change of the height of the seedling tray to ensure that the protective function is always effective. As the seedlings grow, it may be necessary to make a fine adjustment to the height of the seedling tray according to the changes in light and temperature. The lifting mechanism 2 is used again to make a slight adjustment to the height of the seedling tray to meet the needs of different growth stages of the seedlings.
