Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of seedling raising, especially to a seedling raising frame. BACKGROUND

[0002] With the continuous development of agricultural planting and the expansion of planting scale, traditional seedling raising methods have been difficult to meet the modern and large-scale planting needs. As a kind of efficient seedling raising tool, seedling raising frame emerges as the times require. Seedling raising frame is usually carefully crafted from sturdy materials, with a stable structure and the ability to carry a large number of seedlings. Its layered design makes full use of vertical space, allowing more seedlings to be cultivated in a limited area. Each layer neatly holds seedling trays containing seeds or seedlings, providing a suitable growing environment for the seedlings. Seedling raising frame not only facilitates the daily management and care of the growers, but also ensures that the seedlings can evenly enjoy important conditions such as light, temperature, and humidity. At the same time, it also provides convenience for growers to control the environment, allowing them to adjust light intensity and time according to different seedling raising needs. In addition, seedling raising frame also has good ventilation, which helps to reduce the breeding of pests and diseases, creating a healthy growing environment for seedlings.

[0003] For example, Chinese utility model patent (CN218550739U) discloses a seedling raising frame, which solves the problem that the prior art requires one by one watering of the seedling raising boxes when watering the seedlings inside the seedling raising boxes, making watering inconvenient.

[0004] The device includes a base, a seedling raising frame one and a seedling raising frame two. The base is fixedly connected with a water storage frame on the upper end surface. The water storage frame is fixedly connected with a hollow column inside. The water storage frame is fixedly connected with a submersible pump inside. The output end of the submersible pump is fixedly connected with a communication pipe fixedly communicated with the inside of the hollow column. The upper end of the seedling raising frame one and the seedling raising frame two is provided with a water spraying pipe with a spray head. The lower end of the water spraying pipe is fixedly connected with a connecting column fixedly connected with the inside of the corresponding seedling raising frame and the seedling raising frame two. The water spraying pipe provided on the upper end of the seedling raising frame one and the seedling raising frame two is fixedly connected with a water delivery pipe fixedly communicated with the inside of the hollow column. The seedling raising frame of the utility model is convenient for watering the seedlings inside each seedling raising frame, thereby reducing the work intensity of the staff and is more practical.

[0005] When using the above-mentioned technology, it is found that the existing technology has the following technical problems: the device cannot rotate bidirectionally, resulting in the seedlings only being able to receive light on one side.
