Description

[Detailed Description of the Invention] The present invention relates to a side curtain opening/closing device for a plant cultivation house, and an object of the present invention is to make it possible to open and close two side curtains with one prime mover, simplify the opening/closing device, and reduce costs. That is.

Generally, plant cultivation greenhouses are covered with vinyl sheets or the like to keep the inside of the greenhouse warm, but when the temperature inside the greenhouse rises or in the summer, the sheets are opened to adjust the temperature. This sheet is normally opened and closed by opening and closing a sheet that covers the side of the house (hereinafter referred to as a side curtain). Manually opening and closing the side curtains requires a considerable amount of effort, so in many cases an electric motor is used to open and close the side curtains in a roll-up manner.
By the way, when opening and closing the side curtains of a plant cultivation house, there are cases where opening and closing the side curtains on only one side is insufficient.
It may be more effective to open and close two side curtains. Moreover, in the case of a multi-building type plant cultivation house, it is preferable that at least two side curtains are opened and closed. Opening and closing such two side curtains requires two prime movers, which increases the size of the equipment and increases costs.

The present invention relates to a side curtain opening/closing device for a plant cultivation house that solves the above-mentioned problems, and will be described below based on drawings showing one embodiment.

In the figure, reference numerals 1 and 1' indicate plant cultivation houses constructed in a multi-building type, each having side curtains 2 and 2' whose upper ends are fixed to the sides and which hang down. Long rod-shaped winding shafts 3, 3' are fixed to the lower ends of the side curtains 2, 2', and the winding shafts 3, 3' are used to wind up and unwind the side curtains 2, 2'. ，
2' opens and closes. Driving tapered drums 4, 4' and guiding tapered drums 5, 5' are attached to the ends of the winding shafts 3, 3' with their taper directions being the same. Further, one prime mover 6 is provided near the joint between the plant cultivation houses 1 and 1'. This prime mover 6 is composed of a motor and a speed reducer, and has two output shafts 7, 7' which protrude in the same direction via appropriate gears. is installed. Note that the output shaft 7 and the output shaft 7' have opposite rotation directions. That is, if the output shaft 7 rotates in the direction of arrow A, the output shaft 7' rotates in the direction of arrow A', which is opposite to the direction of arrow A.

The drive drums 8, 8' are provided with winding ropes 9,
One end of the winding rope 9' is connected to the winding rope 9,
9' is a roller 1 installed at the upper part of the side curtain 3, 3' of the plant cultivation house 1, 1'.
0 and 10', and the ends thereof are fixed by wrapping an appropriate amount around the larger diameter of the driving tapered drums 4 and 4' than the smaller diameter. Further, guide ropes 11, 11' and unwinding ropes 12, 12' are wound around the guide tapered drums 5, 5'. That is, one end of the guide ropes 11, 11' is fixed to a lower member, and the guide ropes 11, 11' are fixed by wrapping an appropriate amount around the larger diameter guide tapered drums 5, 5' than the smaller diameter one. The winding direction is the driving rope 9,
9' is wound in the opposite direction. One end of the unwinding ropes 12, 12' is fixed to the upper part of the plant cultivation house 1 where the side curtains 2, 2' are installed, and the ropes 12, 12' are connected to the guide tapered drums 5, 5' with the smaller diameter one first. It is wrapped around the larger one in an appropriate amount, and its ends are fixed to guide tapered drums 5, 5'. The winding direction is opposite to the winding direction of the guide ropes 11, 11' around the guide tapered drums 5, 5'. In addition, 13,1 in the figure
Reference numeral 3' denotes a rocking prevention member for preventing rocking when the winding shafts 3, 3' rotate, and is arranged as follows.

That is, as shown in FIGS. 1 to 3, the rocking prevention member is arranged such that the winding shafts 3, 3' are interposed between the side columns 14, 14' of the plant cultivation houses 1, 1'. 13 and 13' are arranged. With this arrangement, even if the winding shafts 3, 3' swing when the side curtain is opened and closed, the range of the swing is limited to the side columns 14, 14' and the swing prevention members 13, 1.
3' and does not swing significantly, the opening and closing operations described above can be performed smoothly.

The side curtain opening/closing device for the plant cultivation house of the present invention is configured as described above, and when opening the side curtains 2, 2', the output shaft 7 of the prime mover 6,
Turn 7' in the directions A and A' shown in the illustration. Due to this operation, the winding ropes 9, 9' are pulled in the direction of the arrow, and the winding shafts 3, 9' are pulled through the drive tapered drums 4, 4'.
3' is rotated in the direction B, B', so that the side curtains 2, 2' are wound around the winding shafts 3, 3'. It rises while winding up '. At this time, the winding ropes 9, 9' and the guide ropes 11,
11' is unwound around the driving tapered drums 4, 4' and the guiding tapered drums 5, 5'. Since there is appropriate tension in the winding ropes 9, 9', the winding shafts 3, 3' move smoothly. Also,
The unwinding ropes 12, 12' support the load of the winding shafts 3, 3' and prevent the side curtains 2, 2' from elongating. The reason why each drum has a taper is due to the change in the winding thickness of the side curtains 2, 2' wound around the winding shafts 3, 3'. This is to compensate for changes in the amount of movement. Next, side curtains 2, 2'
When closing, by reversing the prime mover 6,
Do the opposite of the above.

The side curtain opening/closing device for a plant cultivation house of the present invention performs the above-described operation, and a plurality of side curtains are remotely controlled to open/close by one prime mover, thereby reducing equipment costs.
In addition, the side curtains are opened and closed using a tapered drum.
This can be carried out smoothly using a guide rope, an unwinding rope, and a swing prevention member, and has a great practical effect.

In addition, in this example, the main shaft of the prime mover is 2.
However, as shown in Figure 4, it may be made into one rope, and the two guide ropes may be wound in common and unwound. Therefore, the main shafts of the prime mover are reduced to two. It is not limited.
