Problems solved by technology

[0006] In other words, although the existing products have functions of heat preservation and ventilation, there is a problem that the atmosphere in the cover cannot be properly adjusted
[0007] In addition, if a power source is used to control the growth environment of the seedlings, there will be a problem of costing electricity.
And, in this case, the structure of the cover becomes complicated, and it is inconvenient to use in the home vegetable garden etc.

Embodiment Construction

[0046] Next, a preferred embodiment of the present invention will be described with reference to the drawings.

[0047] like figure 1 Shown by etc., the cover of the present invention is provided with a ventilating part 3 on the upper surface 2a of the light-transmitting cover main body 2 that covers the seedlings 1 . The shape of the cover main body 2 is arbitrary, but is formed in a box shape in this embodiment. Furthermore, the cover main body 2 is made of transparent acrylic resin, is provided with an air layer 2b for heat insulation, and is formed in a double layer.

[0048] The ventilation unit 3 described above is formed of a valve member 5 that opens and closes a ventilation port 4 opened on the upper surface 2 a of the cover main body 2 , and an operating device 6 of the valve member 5 . In the case of this embodiment, the valve member 5 is arranged inside the cover main body 2 . In addition, the operating device 6 is formed to include a shape memory alloy member 6...

Abstract

The invention provides a seedling cover utilizing solar heat. It is possible to adjust the internal temperature and other atmospheres with a simple structure without requiring a power supply. A ventilation part (3) is provided on the upper surface (2a) of the translucent cover main body (2) for covering the seedlings (1). The ventilation part (3) is formed by a valve member (5) and an operating device (6) of the valve member (5). The ventilation port (4) is opened and closed. The operating device (6) includes a shape-memory alloy member (6a), which is deformed by heat energy of sunlight to operate the valve member (5). The shape-memory alloy member (6a) is housed in a transparent case (7), which is formed in an upright shape on the upper surface (2a) of the cover main body (2).

Description

technical field [0001] The present invention relates to a cover used for growing seedlings of crops, and more specifically, to a cover for seedlings using solar heat capable of controlling the growth environment of seedlings by using solar heat. Background technique [0002] Conventionally, as such a cover, for example, a cap-shaped transparent plastic sheet is known (see Patent Document 1). [0003] In this conventional product, an openable vent hole is formed at the upper end of the cap so that ventilation can be performed through the hole. [0004] The existing product of Patent Document 1 is simple to set up, can cover one seedling field one by one, and can be suitable for small-scale use such as gardening full of interest. In addition, when the air temperature rises, by opening the vent hole, it is possible to suppress an increase in temperature inside. [0005] However, for example, during the period between March and May, the atmosphere becomes unstable, and the tem...
