Agriculture automation special seedling growing device

Abstract

The invention discloses an agriculture automation special seedling growing device. The device includes a seedling growing disc, a culture box, a heat preservation mechanism and an automatic supply mechanism, wherein the culture box, the heat preservation mechanism and the automatic supply mechanism match with the seedling growing disc. Seedling growing cups are arranged on the seedling growing disc. The seedling growing cups are provided with air vents, overlap rings and water holes. The culture box is divided into a gas phase layer and a liquid phase layer. The gas phase layer and the liquidphase layer are separated by a separator plate. The separator plate is provided with overlap ports. The automatic supply mechanism includes a miniature ball float controller, a liquid inlet pipeline and a solenoid valve. The heat preservation mechanism includes a heat preservation box and a heater box. The device of the invention has a simple structure and reasonable design. Compared with a conventional seedling growing disc, the device has a better culture effect. And gas and liquid are separated, which can prevent the volatilization of a nutrient solution and save the seedling growing cost.Compared with a part of integrated culture seedling growing discs, the device has separated design which is more convenient and makes the maintenance more convenient. Meanwhile, the heat preservationmechanism and the automatic supply mechanism match with the device, and so the automatic heating and heat preservation of the nutrient solution can be realized and the nutrient solution can be automatically supplied which improves the automation degree of seedling growing.

Description

technical field [0001] The invention belongs to the field of agricultural automation, and in particular relates to a special seedling raising device for agricultural automation. Background technique [0002] Seedling tray, as an important seedling device, also called plug tray, is an important tool in the industrial seedling production process, and it is also the most fundamental change in modern horticulture, providing a guarantee for fast and mass production. [0003] However, the old-fashioned seedling trays currently used need to be equipped with a cultivation box when cultivating seedlings, and the old-fashioned cultivation boxes lack support for the seedling tray, which may easily cause the seedling tray to collapse from the middle and affect the seedling effect. At the same time, due to the gas-liquid The two phases cannot be effectively separated, the volatilization of the culture solution is very serious, and the cost of seedlings increases; at the same time, some c...

Problems solved by technology

[0003] However, the old-fashioned seedling trays currently used need to be equipped with a cultivation box when cultivating seedlings, and the old-fashioned cultivation boxes lack support for the seedling tray, which may easily cause the seedling tray to collapse from the middle and affect the seedling effect. At the same time, due to the gas-liquid The two phases cannot be effectively separated, the volatilization of the culture solution is very serious, and the cost of seedlings increases; at the same time, some companies have improved the seedling trays and obtained some integrated seedling trays. Combined into one body, the gas-liquid two-phase supply is carried out through the built-in pipeline, which can effectively prevent the volatilization of the culture medium, but there are also some problems. First, the weight is heavy and it is not easy to carry. Secondly, the pipeline is not easy to clean and difficult to maintain.

[0004] Moreover, most of the seedling trays currently used cannot realize the automatic supply of culture fluid, and the degree of automation is low.
