All-weather efficient solar drying box and greenhouse

Abstract

The invention relates to an all-weather efficient solar drying box and greenhouse, in particular to an all-weather efficient solar drying box used for a greenhouse and an all-weather efficient solar greenhouse adopting the drying box. The all-weather efficient solar drying box comprises a tunnel type casing mounted on a base, wherein a drying frame is arranged in the casing, a first air vent is formed in the upper part of the front part of the casing, a front door is mounted at a front end port of the casing, a fan corresponding to the front end port is arranged on the front side of the casing, a second air vent is formed in the upper part of the rear part of the casing, a control valve is arranged at the second air vent, a rear end port of the casing is closed by an air source heat pump, and an air outlet of the air source heat pump is communicated with the casing. According to the all-weather efficient solar greenhouse, at least one set of all-weather efficient solar drying box is longitudinally arranged in the drying chamber. All-weather use requirements are met, the drying effect is good, energy loss is low, the building cost of the greenhouse is low, and the economic benefit is good.

Description

technical field [0001] The invention relates to an all-weather solar high-efficiency drying box and a greenhouse, in particular to an all-weather solar high-efficiency drying box for greenhouses and an all-weather solar high-efficiency greenhouse using the drying box. Background technique [0002] my country is a large agricultural country, and agriculture is the primary industry. With the continuous progress of society, the traditional agricultural production mode can no longer meet the needs of the development of modern civilization. New agricultural facilities continue to develop. Greenhouses are not limited by time and space. , can carry out agricultural production in special environments such as plateaus, deep mountains, and deserts, and is favored by people. [0003] Due to its good heat absorption effect, warm greenhouses are usually divided into a drying room on the upper part of the greenhouse. A drying rack is placed in the drying room, and plants that need to be dr...

Problems solved by technology

However, when encountering continuous rainy days or snowing in winter, on the one hand, due to lack of sunlight, the temperature in the drying room cannot meet the requirements, and the drying cannot be completed; on the other hand, due to the relatively humid air, the air flow in the drying room is poor , causing moisture to be difficult to volatilize, causing the plants to be dried to become moldy and reduce production, causing losses to growers

[0004] The drying room in some greenhouses is heated by electric heating or hot water. Although it is not affected by the climate, it has high energy consumption, high cost and no ventilation effect.
