Description

[Detailed Description of the Invention] (Industrial Application Field) This invention can be used throughout the year to reduce seasonal temperature changes, and to maintain an appropriate environment in hydroponic fields, especially for cultivating wasabi, etc. The present invention relates to an agricultural environment adjustment device that adjusts the environment to a suitable condition.

(Prior art) Devices have been known to protect crops from direct sunlight, rain, wind, frost, snow, birds, insects, etc. by covering fields with nets or sheets. There is.

For example, a large pole set up on the ground is protected from direct sunlight and birds by installing a conical net around it (Utility Model Publication No. 57-37954, Utility Model Application Publication No. 59-1982).
52852 etc.).

In addition, a tea garden frost-proofing cover (Utility Model Application Publication No. 56-66246) has been proposed, in which a lightweight net with a low light shielding rate is stretched over the tea garden in a mountain shape.

(Problems to be Solved by the Invention) All of these conventional protection devices use one type of covering material selected from among nets and sheets. So, for example, if you use a mesh net,
It is suitable for protecting from direct sunlight, frost, snow, birds, etc., but rain and snowmelt water can penetrate through the mesh. In addition, if a waterproof sheet is used, it may be damaged by rain, wind, frost, snow, birds, insects, etc.
While this makes it possible to protect people from such things, there are problems such as a lack of ventilation, which increases the temperature inside and outside.

Furthermore, if the same covering material is used throughout the seasons,
The temperature inside the seat becomes proportional to the environmental temperature around the seat to some extent. Therefore, although the temperature inside the seat is lower than the environmental temperature around the seat, changes in air temperature occur due to temperature differences between the four seasons.

However, wasabi cultivation does not like direct sunlight, and is said to be best in a cool climate (12°C to 15°C) with little seasonal variation in temperature or water temperature. Therefore, when using conventional sheets of this type, depending on the season,
It is necessary to attach and detach the sheet and change it for each purpose, which causes an inconvenience that reduces work efficiency.

Therefore, the present invention was created to solve the above-mentioned problems. - It can be used throughout the year, has good ventilation, and blocks direct sunlight, and is particularly suitable for cultivation of wasabi. The purpose is to provide an agricultural environment adjustment device that can set special environments.

(Means for Solving the Problems) In order to achieve the above-mentioned problems, this invention has the following features: A wire 2 is stretched from the top of a column 1 erected in a field P to the ground around the field P, A waterproof sheet 4 is coated on the wire 2 extending from the top of the body 1 to a proper position downward, a mesh-like net 5 is coated on the wire 2 extending from the waterproof sheet 4 further downward, and a mesh net 5 is placed on the side of the column 1. A water sprinkler 6 forms a support 3 that is fixed and supports the tarpaulin sheet 4 and sprays water on the tarpaulin sheet 4.
A means for solving the problem is to provide this on the top of the waterproof sheet 4.

(Function) According to the present invention, the covering waterproof sheet 4 and the net 5 are supported by the wires 2 stretched from the top of the column 1 erected in the field P to the ground around the field P. Ru.

The tarpaulin sheet 4 has a water sprinkler 6 installed on the top of the tarpaulin sheet 4.
It receives water sprinkled from the waterproof sheet 4 and causes the water to widely flow toward the net 5 below the tarpaulin sheet 4. Furthermore, this water is transmitted from the tarpaulin sheet 4 to the net 5, which adjusts the environmental temperature of the field to a constant level.
It also melts the snow on the water sprinkler 5.

In addition, the waterproof sheet 4 protects the fields from rainwater in addition to the water from the sprinkler 6, and adjusts the amount of sunlight blocking by appropriately selecting the translucency of the waterproof sheet 4.

The net 5 improves ventilation and adjusts the temperature of the outside air passing through the net to the water temperature level by the water from the water sprinkler 6 that passes through the net.

A column 1 erected in a field supports a waterproof sheet 4 and a net 5 via a support 3.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 shown in the figure is a column, and this column 1 is to be erected in a field, and concrete pile is planned to be used as the material of the column 1. This concrete pile has standards such as 12m, 10m, 8m, etc.
Suitable for use depending on the size of the field. The illustrated column 1 has a length of 12 m, and is buried 4 m deep in the ground. Furthermore, in this example, five pillars 1 are used for a field with a width of 20 m and a length of about lll[lrn (see Fig. 1).

Reference numeral 3 indicates the waterproof sheet 4 via the support rod 7 and the wire 2.
and a support for supporting the net 5.

The illustrated support body 3 has support arms extending in all directions from the column body 1 and supporting the upper end of the column body 1 and a pipe-shaped support rod 7 disposed along the long throw direction of the column body 1. 3A, and on the other hand, a connecting member 3B that connects the support rods 7 located apart from the column 1 to each other is formed (see Figs.
(see figure).

At this time, the support arm 3A is provided to be swingable in the vertical direction, and the connecting member 3B is provided to be adjustable in length, thereby facilitating the installation work of the support body 3. The illustrated connecting member 3B connects one rod fixed to the column 1 to the support rod 7.
The part connected to the main body is branched into two parts to form a Y-shape in plan view, and the length of the part is adjusted by forming the part to be slidable. Further, by providing the fixed portions of the support arm portion 3A and the connecting member 3B to the column 1 so as to be slidable with respect to the column 1, there is an advantage that they can be easily adapted to the shape of the field.

Furthermore, in the case of supporting a ring-shaped support rod 7, it is also possible to use a support body 3 that serves as both the support arm portion 3A and the connecting member 3B (see FIG. 4).

The means of fixing the wire 2 uses an anchor 8 driven into the ground (see Figure 2), but is not limited to this fixing means, and conventionally known methods such as using piles can be used depending on the situation of the land. The fixing means can be appropriately selected from among the following fixing means.

The water sprinkler 6 sprinkles water onto the waterproof sheet 4, and it is preferable to use underground water with a constant temperature, but stream water or tap water can also be used.

This water sprinkler 6 uses a predetermined pump 6B to send water to a water pipe 6A disposed on the top of the waterproof sheet 4, and uniformly sprinkles water onto the waterproof sheet 4 from the drain port of the water pipe 6A. This water sprinkling is used not only to extinguish lightning in the winter, but also to suppress temperature rises in the summer.

Note that the illustrated waterproof sheet 4 is a transparent waterproof sheet 4 for purposes of explanation.
However, the transparency of this tarpaulin sheet 4 can be arbitrarily selected depending on the cultivar to be cultivated and location conditions.
In particular, the waterproof sheet 4 with a high light shielding rate is suitable for hydroponic fields where wasabi is cultivated.

(Effects of the Invention) This invention achieves its original purpose by being configured as described above.

In other words, from the top of the column 1 erected in the field P
A wire 2 is stretched toward the ground around the pillar 1, and a waterproof sheet 4 is coated on the wire 2 extending from the top of the column 1 to an appropriate position downward. By covering the net 5 of the shape, the waterproof sheet 4
Since the net 5 blocks rainwater and sunlight and improves ventilation within the field, the environment such as temperature and humidity within the field can be kept constant.

In addition, by forming a support 3 that is fixed to the side of the column 1 and supporting the tarpaulin sheet 4, and by providing a water sprinkler 6 on the top of the tarpaulin sheet 4 for spraying water on the tarpaulin sheet 4, waterproofing in winter can be achieved. It is possible to melt the snow on the sheet 4 and the net 5, and also has the effect of suppressing the rise in temperature in the fields in the summer, and as a result - it is possible to maintain a constant environment in the fields throughout the year. . Therefore, when cultivating wasabi, direct sunlight is not preferred, and a cool climate (12
Even in a special environment where the temperature is 15°C to 15°C and there is little change in temperature or water temperature depending on the season, the environment can be set in any field using the apparatus of the present invention.

As mentioned above, according to the present invention, it can be used throughout the area, and by blocking direct sunlight while providing good ventilation, it is particularly suitable for industrial applications such as setting up special environments such as wasabi cultivation. It has excellent effects.
