PROBLEM TO BE SOLVED: To reduce damage caused by contact with various films set in/out of an agricultural greenhouse.SOLUTION: The agricultural film support member can reduce damage caused by contact with a film because the friction resistance in a contact part in contact with the film is low. It is important for various equipment used in the agricultural greenhouse to prevent impairment of sunlight conditions caused by setting the equipment, and also for the agricultural film support member, it is desirable that the area of projection of the agricultural film support member when the agricultural film support member is set is as small as possible. Accordingly, the outer diameter (diameter) of the agricultural film support member is desired to be as narrow as possible. However, the narrower the diameter of the agricultural film support member is, the greater the damage to the film caused by local breaking is. As the friction resistance in the contact part is small, the degree of damage to the film caused by the local breaking can be reduced even if the outer diameter is narrow. By using a narrower agricultural film support member, the sunlight conditions can be further improved.

PROBLEM TO BE SOLVED: To provide a greenhouse cultivation system achieving energy-saving and a high yield at a low cost.SOLUTION: The greenhouse cultivation system is formed by arranging in a greenhouse 10, a heat exchange-thermal storage device 30 which is installed on the side, with a heat transfer plate 32 promoting heat exchange between greenhouse air and a thermal storage body filled in the inside, and arranging a heat pump 50. Daytime surplus heat in the greenhouse is efficiently heat exchanged through the heat transfer plate 32 of the heat exchange-thermal storage device 30 by the temperature difference between the thermal storage body filled in the heat exchange-thermal storage device 30 and greenhouse air. As a result of this, it is possible to reduce the operating efficiency of the heat pump 50, contribute to daytime cooling and shortening of the ventilation time, and supply stored heat to heating at night to greatly reduce cooling and heating cost.

PROBLEM TO BE SOLVED: To prevent the damage to a film. SOLUTION: This film-protecting member 50 for a green room, characterized by having a guard portion 51 laminated along a frame member 11 to the frame member-covered portion 12b of a fixed film, in order to prevent the direct contact of a film-rolling pipe 40 with the frame member-covered portion 12b placed on the frame member 11 stably supporting the operation of the rolling pipe 40. Thus, the film-rolling pipe 40 is directly not brought into contact with the frame member-covered portion 12b of the fixed film 12, thereby enabling to prevent the deterioration and damage to the fixed film 12 due to the contact of the rolling pipe 40 with the frame member-covered portion 12b.
Abstract:
PROBLEM TO BE SOLVED: To prevent the meander of a guide pipe followed by heat shrinkage of a curtain. SOLUTION: A long groove 21 is longitudinally formed on the outside of the guide pipe 2 for guiding and opening and closing the curtain 8. A curtain connection tool 3 includes its gripping part 31 having an inner diameter larger than the outer diameter of the guide pipe 2 and the curtain 8 is laid slidably in the length direction of the guide pipe 2 between the curtain connection tool and the guide pipe 2. The curtain connection tool is provided with a linear projected part 32 to be connected to the long groove 21. Consequently, even if the curtain is thermally shrunk, the curtain connection tool 3 is moved with following the thermal shrinkage or only the curtain 8 is moved to prevent the meander of the guide pipe 2.
Abstract:
PROBLEM TO BE SOLVED: To provide a greenhouse curtain device capable of stretching curtain members in double layer with an easy structure, forming an air layer between each curtain member, and further increasing heat insulation effectiveness. SOLUTION: This greenhouse curtain device has a lower rack wire 19 below an upper rack wire 18 which supports an upper layer curtain member 30, and comprises letting the lower rack wire 19 support a lower layer curtain member 40 to form an air layer between the upper layer curtain member 30. The lower layer curtain member 40 is opened and closed together with the upper layer curtain member 30. Since a mechanism to operate the upper layer curtain member 30 functions as a mechanism to open and close the lower layer curtain member 40, it is possible to make a double layer type with a minimal number of parts and increase heat insulation effectiveness by the air layer.

Abstract:
PROBLEM TO BE SOLVED: To decrease a dead space to which a liquid is not supplied by making the length of a series of hose-supporting carriages shorter than that of a conven tional device, when the carriages are brought into contact with each other and ranged in line. SOLUTION: A liquid spraying device is connected to a travel rail 40, and is provided with rails 50 for housing having a plurality of stages of rail parts 53, 58 from the top to the bottom. In addition, this device uses a hose-supporting carriage 20 having auxiliary wheels 30, which rotate independently of travel wheels 21 running on the travel rails 30 and runs only on a rail part 58 of the rails 50 for housing, and a hose-supporting carriage 10 having no auxiliary wheel. As a result, the hose-supporting carriage 20 having the auxiliary wheels 30 and the hose-supporting carriage 10 having no auxiliary wheel can be accommodated in different rail parts 53 and 58 in the rails 50 for housing.
Abstract:
PROBLEM TO BE SOLVED: To enable various kinds of target members of action in a greenhouse to act automatically according to the change of temperature even without an electric source, and simultaneously to enable an electrically driven structure to be switched. SOLUTION: A piston 122 is elongated according to the volume expansion of a driving material to elongate a movable shaft 140 linked to the piston 122. The movable shaft 140 separates a side ventilation window linked through a link structure to the movable shaft 140 from the side surface of the greenhouse. Simultaneously, a pressing part of the movable shaft presses a lever of an operation switch to operate an ventilation fan for exhausting the heat. As a result, a running cost and an installation cost are reduced because the opening and closing of the side ventilation window and the switching of the ventilation fan for exhausting the heat can be carried out automatically according to the change of the temperature even by using no electric source.
