Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an aeration system for a horticultural greenhouse such as a greenhouse or tunnel used for cultivating or growing vegetables, fruits, flowers, etc.

[Conventional technology]

In recent years, the length of gardening greenhouses and gardening tunnels has increased by 1
From around 0m to long ones 100m to 150m
As the length of the room increases, the burden of ventilation operations for controlling the indoor temperature becomes extremely large.

Conventionally, to open and close the ventilation holes in a greenhouse, the side sheets are generally pulled up by hand starting from the end, and tied up in sequence with strings attached to the phalanges at appropriate intervals to open the ventilation holes, and conversely, to let outside air into the room. If you did not want to insert paper, you would tie up the sheet, unravel each piece of paper one by one, and let the sheet hang down to close it. In addition, ventilation operations for tunnels are generally carried out either by folding up one side of the overturned sheet and gathering it on the other side to completely open the tunnel, or by rolling up the sheet from both sides along the entire length of the tunnel and narrowing it to the center of the ceiling. Gather them together and tie them with string. By doing this sequentially at intervals of about 5 to 6 meters from one end of the tunnel to the other, both sides of the tunnel are opened to allow air to pass through. When you want to overturn a sheet for a pen pal, and the sheets are bunched up on the other side, first spread the sheet a little beyond the top of the tunnel, do this over the entire length, and then turn the sheet over to the opposite side in the width direction of the tunnel. Spread the sheet halfway around the area and lower it to cover the soil on one side opposite to the other side.

In addition, as for other conventional tunnel technology, as mentioned above, opening and closing the tunnel is very troublesome and takes a lot of time, so in order to solve this problem, the applicant filed a utility model application. The technology is disclosed in the publication, and the technology involves attaching slide fasteners to the seats of the tunnel along the entire length thereof in the longitudinal direction, and opening and closing the seats using these slide fasteners.

[Problem that the invention seeks to solve]

In the above-mentioned house, the side sheets are manually tucked up from the end and then tied up with strings attached to the phalanges at appropriate intervals, so it is not only necessary to tuck up the sheets.

Even when lowering the vehicle, a large number of strings must be untied one by one, and this operation is extremely troublesome and time-consuming, and also takes a surprisingly large amount of time. This is a house with a length of 100 m or more.
It was especially troublesome and time-consuming for long lengths of 150 meters, and it had the disadvantage that it could not be completed in time if it was urgently needed.

In addition, in the tunnel with the slide fastener,
Although opening and closing the seat is easier and faster than with a tunnel without a slide fastener, the operator has to pick the slider pull of the slide fastener with his/her hand to open and close the fastener, so the height of the tunnel If the width is small, the worker will have to bend down and walk along the side of the tunnel to open and close the zipper.

Furthermore, if the height and width of the tunnel are large, the slide fastener may be difficult to reach depending on its position, making it extremely difficult to open and close the slide fastener. This difficulty becomes more noticeable when the tunnel is long, so it was a major problem that needed to be resolved.

Therefore, the purpose of this invention is to solve the above-mentioned problems.Even in a horticultural greenhouse such as a considerably long greenhouse or tunnel, the greenhouse opening can be opened and closed to adjust the temperature of the greenhouse or exchange the air. The object of the present invention is to provide a ventilation device that can be easily and quickly used.

[Means for solving problems]

The ventilation device for a horticultural greenhouse according to the present invention is a deep horticultural greenhouse in which the frame is covered with a sheet, and the sheet is provided with a long opening/closing opening using a slide fastener along the longitudinal direction of the greenhouse, and the opening/closing opening is A plurality of sliders for opening and closing the zipper are arranged at equal intervals in the longitudinal direction, and each of the sliders is connected to an operating strip that is freely movable along the entire length of the opening/closing opening. be.

By drawing them together, the ventilation 11 can be opened and closed at regular intervals along the entire length of a horticultural greenhouse such as a greenhouse or a tunnel.

〔Effect of the invention〕

The ventilation system for a horticultural greenhouse according to the present invention has the following features: (1) A slider is connected to an operating strip installed along the opening and closing, and by pulling the operating strip, the slider is slid to open and close the ventilation opening. This eliminates the need for workers to walk along the house when opening and closing the openings, and they can open and close the vents on the side of the house along the entire length of the house while standing at one corner of the house. This makes it easy to open and close the opening for ventilation.

(2) When the long opening/closing opening of the seat is opened or closed by pulling the operating rod, each slider slides the long opening/closing opening by the length between adjacent sliders using a plurality of sliders arranged at equal intervals. This allows you to open or close all long openings at once, so even if you have a very long opening in a deep horticultural greenhouse, you can open and close the entire opening over its entire length in a fraction of the time. It can be opened and closed at a speed of one or a few tenths of a second.

Therefore, if the weather suddenly changes (a typhoon suddenly changes direction and approaches, or the wind and rain suddenly become stronger)
The effect is greatly recognized in cases such as when seeds are falling.
