Description

  The present invention relates to a greenhouse curtain opening / closing device.

  Conventionally, as shown in FIG. 11, the framework of the greenhouse 100 includes a central pillar 101 built at intervals in the ridge direction, side pillars 102 built on both sides thereof, and a purlin that connects the central pillars 102. The roof material 103 that connects the purlin and the side pillar 102 and the reinforcing staff 104 disposed between the central pillar 101 and the roof material 103 are often used (see Patent Document 1).

  When installing a curtain opening / closing device in this type of greenhouse, since the central pillar 101 and the cane 104 are present in the greenhouse, the curtain opening / closing device must be separated for each central pillar 101 and It must be configured at a position lower than the cane 104.

  Then, the drive shaft 303 of the drive wire 302 that drives the curtain 301 can be one in the ridge direction of the greenhouse 100, but the drive wire is connected to each of the curtain opening / closing devices divided for each central pillar 101. 302, its winding drum, pulleys for changing the direction of the drive wire, and the like are required, and the number of parts as a whole is required, and the installation cost of the curtain opening / closing device becomes enormous.

On the other hand, as shown in FIG. 12, a curtain opening and closing device that opens and closes by moving a curtain in a greenhouse ridge direction has been proposed (see Patent Document 2).
Since this type of curtain opening and closing device only needs to place the drive shaft on the surface of the greenhouse, it is possible to reduce the number of components such as the drive wire, its winding drum, and direction change pulley. The installation cost of the curtain opening and closing device can be considerably reduced.

However, since this greenhouse is provided with a large number of beams that are spaced in the ridge direction and parallel to the wife surface, the curtain opening and closing device must be flattened along the lower surface of these beams. In a low greenhouse, the problem remains that the cultivation space is narrowed with the curtains closed, which reduces the work efficiency of the grower.
On the other hand, in order to ensure workability, it is necessary to set the height of the greenhouse above a certain level, which causes a problem that the construction cost of the greenhouse itself increases.
