Abstract

PURPOSE:To provide the title mechanism so designed that plural rows of light- transmissible flexible tubes are adjacently arranged, and tubes adjacent to each other are ensured to be mutually adhered when expanded by a fluid, thereby making a ready changeover of the house environment between closed system and open system. CONSTITUTION:A blower 1 and a blowing pipe 2 having plural branch pipes are mutually connected via an electromagnetic valve 7, and flexible tubes 3 through which corresponding number of rays can be transmitted are linked to the branch pipes, respectively. Each tube 3 is suspended with a supporting wire 4 and set up in a stretched manner, forming, in combination with the sidewalls 6, a greenhouse on the ground 9. When each tube 3 is expanded by a fluid, a continuous plane 8 is formed between mutually adjacent tubes, thus forming a closed system. A plural of fluid delivery ports are provided at the lower part of each tube 3, and using these ports, carbon dioxide, fumes for pest control, highly humid air for temperature control, etc., can also be fed.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a greenhouse for agriculture and horticulture, and more specifically, to a greenhouse for expanding the cropping period of field crops and avoiding low-temperature damage, especially in cold regions. This relates to a tube-shaped greenhouse cultivation environment control mechanism.

[Conventional technology]

In general, greenhouses for agriculture and horticulture are made up of a closed system consisting of a framework made up of pillars and other supporting materials, covered with a light-transmitting sheet such as vinyl, but closed greenhouses also have a means for ventilation, that is, an open system. Formation means are essential.

For this reason, ordinary houses are equipped with ventilation fans, skylights, side windows, etc., and tunnel houses are ventilated by lifting vinyl sheets manually, making it difficult to scale up the house. Furthermore, other additional measures and operations are generally required for plant growth control, pest control, and humidity control.

[Problem that the invention seeks to solve]

In view of the above-mentioned circumstances, the present invention allows the formation of an open system to be performed extremely easily and effectively, has a higher heat retention effect, and can automate plant growth control, pest control smoke, humidity control, etc. Furthermore, the present invention aims to provide a house environmental control mechanism that can be made large-scale and still require fewer frame materials such as supports.

[Means for solving problems]

The tube-type house environment control mechanism according to the present invention has a plurality of rows of light-transmitting flexible tubes, such as vinyl films, fixed at least at both ends, so that they are adjacent to each other so as to form a continuous surface when expanded by a filling fluid. and place it,
A fluid is conveyed and supplied from a fluid conveying machine such as a blower through a fluid conveying pipe to inflate the tubes, bringing each adjacent tube into close contact with each other, and constructing a closed system by the continuous surface between the tubes thus formed. If necessary, a plurality of fluid discharge ports with or without valves that open depending on pressure or flow rate may be provided at the bottom of each tube to supply carbon dioxide gas for growth control, mist for pest control, etc. The structure also enables the supply of high-moisture air for humidity control.

The material, thickness, etc. of the tube can be appropriately selected depending on the scale, shape, type, etc. of the house to be formed.

In the present invention, the plurality of rows of tubes are not simply fixed at both ends, but are generally preferably arranged adjacently using tube support wires. The tube support wire may support the upper portion of the tube by any means or manner, or may be disposed at the upper and lower portions of the tube to support the tube on both the upper and lower sides.

If the tube is supported from both sides as in the latter case, it is possible to prevent unexpected accidents such as the tube turning over during strong winds and not being able to form a closed system.

The fluid can be conveyed to each tube arranged adjacently in this way either in parallel, that is, the fluid is conveyed directly from the fluid conveying pipe to each tube, or in series, that is, from the fluid conveying pipe. There may be a method in which the fluid is first conveyed to the first tube, then the fluid is conveyed to the tubes in the adjacent row, and then the fluid is conveyed to the successive tubes to fill the entire tube.

In addition, a fluid outlet may be provided at the end of the tube fluid conveyance system in a series or parallel type, and the size of the fluid outlet may be changed. .

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, non-limiting examples of the tube-type house environment control mechanism of the present invention shown in the accompanying drawings will be described.

First, FIG. 1 (plan view) and FIG. 2 (front view) show a tube-type house environment control device in which tubes are arranged in parallel.

In this device, a blower 1 and a blower pipe 2 having a plurality of branch pipes 2'' are connected via an electromagnetic valve 7, and a corresponding number of vinyl tubes 3 are connected to the branch pipes 2''. Each tube 3 is suspended at both ends by a tube support wire 4 fixed to a wire fixing pipe 5 and a blower pipe 2, and thus the entire vinyl house is placed on the ground 9 together with the side wall vinyl 6. (However, the frame members that assemble the house are not shown).

The tubes 3 are arranged adjacent to each other at such intervals that a continuous surface 8 can be formed between the adjacent tubes when expanded by the filled fluid such as air, and when the continuous surface is formed, the house is closed. Configure the system.

Conversely, when the air supply is stopped and the fluid in the tube is drawn out, for example by opening a fluid outlet (not shown) at the end of the tube, the tube contracts as shown by the dotted line in FIG. , each tube is separated so that there is no longer a continuous surface 8, and the house thus constitutes an open system.

Although not shown, it is possible to provide a tube support wire at the bottom of each tube 3. In that case, the tubes may be inverted during strong winds, preventing the formation of a continuous surface and preventing a closed system from forming. This can prevent the tube from forming or becoming entangled with the support wire.

Furthermore, in FIG. 1, the fluid is conveyed from each branch pipe 2' to the tube 3 as indicated by the arrows.
Instead of such parallel fluid movement, for example, a conveying pipe communicates only with a first tube, a second tube communicates with a first tube at its end and a third tube at its other end, and the following The tubes also communicate with the tubes before and after each,
It is also possible to create a serial fluid movement format in which the fluid that enters the first tube is sequentially sent to the second tube, third tube, and fourth tube, filling each tube with gas. be.

In the house device shown in FIG. 4, for example, a blower pipe 2 and a wire fixing pipe 5 are arranged on adjacent ridges 10, 10 on the ground 9, and a vinyl tube 3 with a plurality of discharge ports is inserted between them. The hanger can be constructed by constantly blowing air through the passing tube to create a house using the tension of the tube 3, or
Alternatively, a fluid ejection support house is constructed by the reaction force of air ejected from the discharge port.

In the figure, 4'' is an auxiliary support member for arranging the tubes 3 or for holding the tubes 3, and does not necessarily have to be a wire.

Figures 5 (a) to (d) show the applied arrangement rows of tubes; (a) is for a flat house, (b) is for a tunnel type house, and (C) and (d) is for a roof type house. It is an example of each arrangement of a tube.

Fig. 5(C) or Fig. 5(d) can be used very conveniently not only as a gardening facility but also as a livestock shed, for example.

Furthermore, the house shown in FIG. 5(d) is suitable for areas with snowfall.

If the tube 3 does not have a discharge port 3', the temperature and humidity inside and outside the house and the pressure inside the tube are detected, and the rotational speed of the blower 1 is controlled to perform optimal environmental control within the device. For example, when the temperature inside the house rises above a certain value, the solenoid valve 7 is opened.
The blower is stopped to stop fluid conveyance, and when the temperature falls below a certain value, the electromagnetic valve 7 is opened and the blower AL is operated to carry out fluid conveyance.

Also, if the temperature is at a pressure below a certain value, fluid transport is performed, but if the pressure inside the tube is below a certain value necessary to maintain the continuous surface 8, fluid transport is performed, and if the pressure is above a certain value, fluid transport is performed. If so, close the solenoid valve and stop fluid transfer.

On the other hand, when the tube is provided with a large number of fluid discharge ports 3 (FIG. 3), the continuous surface 8 can be maintained and the fluid can be supplied into the device by operating the blower 1 and transporting the fluid.

When the carrier fluid can be sent into the device from the tube as in this embodiment, the fluid is circulated by being sent from inside the house to the carrier machine, for example, through the ground. You can.

Further, as shown in FIG. 4, when air is blown out from the discharge port, the tube can be supported by the reaction force like a jet hose head, so a relatively large-scale house can be constructed.

〔effect〕

The present invention is configured as described above, and the house environment can be automatically and easily switched from a closed system to an open system and vice versa. Therefore, simply by changing the house environment to a closed system, the heat retention effect can be increased. By switching to an open system in a timely manner, it is possible to prevent humidity damage or introduce rainwater into the greenhouse in an appropriate amount.Furthermore, when a fluid outlet is provided in the duplex, it is possible to control the growth of plants, It has the effect of automating pest control fumes, humidity control, etc., and making greenhouse cultivation possible on a large scale.
