Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an irrigation system for holding an irrigation tube having a pair of ear-shaped portions extending along the length direction and having a plurality of irrigation holes formed in the length direction. The present invention relates to a holder for a tube.

[0002]

2. Description of the Related Art Generally, when cultivating a plant such as a vegetable in an open field or in a plant cultivation house (hereinafter referred to as a house), the cultivated plant is planted by a watering tube (hereinafter referred to as a tube). Water the furrows.
The above-mentioned tubes are arranged at different positions depending on the watering method. However, in order to uniformly water the entire ridge, the tubes are usually provided by a so-called ground installation method or a side nozzle method. In the above-mentioned ground installation method, tubes are laid between ridges or on the ridges, while in the above-described side nozzle method, tubes are arranged on both side walls of a house, for example. Then, by spraying water from a watering hole formed in these tubes, watering is performed on the entire ridge.

Here, in plant cultivation in the open field, when water does not flow through the tube, the tube may be blown off by the wind to shift the installation position, or the tube may be turned upside down by the wind, making it impossible to spray water. This is because the tube becomes flat and light during non-water passage. By the way, at the time of passing water through the tube, the weight of the passed water presses the tube against the ground, so that the tube is not blown off by the wind.

[0004] Therefore, for example, Japanese Utility Model Publication No. 3-39022 and Japanese Utility Model Publication No. 3-41833, a tube for irrigation is held by a holder and fixed to the ground. Specifically, in these conventional techniques, the tube is pressed integrally with the holder by pressing the tube against the gantry by the pressing member, and inserting the insertion portion attached to the opposite side of the gantry from the tube mounting side to the ground. They are fixed to the ground. This avoids the above-mentioned inconvenience when water does not flow through the tube.

The second grooves 2b, 2b are formed below the first grooves 2a, 2a via the side walls 2d, 2d, and have the same structure as the first grooves 2a, 2a. That is, the second groove portions 2b, 2b are formed by making cuts in a horizontal direction so as to allow the pair of ear-shaped portions 31, 31 of the irrigation tube 30 to pass therethrough. The pair of ear-shaped portions 31 are inserted when both water is passed and when water is not passed. In particular, when water is passed through the irrigation tube 30, the second groove portions 2b, 2b allow the irrigation tube 30 to move upwardly from the ear-shaped portions 31, 31 or to be moved upward.
Of the side wall 2d
The irrigation tube 30 is prevented from escaping from between 2d. As a result, the irrigation tube 30
Is held and fixed at a predetermined position and a predetermined angle by the second grooves 2b.

The maximum width D2 of the second groove portions 2b in the cutting direction is the folding diameter W2 of the irrigation tube 30 when water is not passed.
It is formed about 2 mm larger than (see FIG. 2B). Thereby, the irrigation tube 30 in a flat state is formed.
Can be easily inserted into the second grooves 2b, and can be easily extracted from the second grooves 2b.

The concave portion 2c has a concave shape curved along the lower peripheral surface of the irrigation tube 30, for example, and the outer wall 2g forming the concave portion 2c is similarly curved. Thereby, the irrigation tube 30 inserted into the holding part 2 is supported not only by the pair of second grooves 2b and 2b but also by the concave part 2c, so that the holding part 2 is surely and stably held. Become.

One end surfaces of the side walls 2d are formed with a pair of ear portions 21 of the irrigation tube 20 by the first groove portions 2a.
The irrigation tube 20 is curved so as to be in contact with a part of the peripheral surface of the irrigation tube 20 when the irrigation tube 20 is inflated by passing water. As a result, the irrigation tube 20 is supported not only by the first grooves 2a, 2a but also by the side walls 2d, 2d. Further, it can be stably held.

The distance E2 between the side walls 2d is substantially equal to the outer diameter R2 (see FIG. 17) of the irrigation tube 30 excluding the pair of ears 31. Even in this case, the irrigation holes 32a _1.
32b ₁ · 32a ₂ · 32b ₂ are exposed from between the side wall 2d · 2d, even watering tube 30 has been held by the holder 1, it does not occur trouble in watering.

The width F1 of the holding section 2 along the length direction of the irrigation tubes 20, 30 is not particularly limited.

The holder 1 has a flat plate 3. The flat plate portion 3 is a bottom portion of the holding portion 2, that is, the outer wall 2g.
Irrigation tube 2 held by holding section 2 from the bottom of
It is provided to extend in the width direction of 0.30. And
The holding portion 2 and the flat plate portion 3 are connected to each other by a flat plate-shaped connecting portion 4 extending in the vertical direction at a substantially central portion in the insertion direction of the irrigation tubes 20 and 30 other than the bottom portion. Further, a peg portion 5 (insertion portion) to be inserted into the ground or a pipe is provided on a side of the flat plate portion 3 opposite to a side holding the irrigation tubes 20 and 30.

The peg portion 5 is formed integrally with the holding portion 2 and the flat plate portion 3 so as to hang down below the holding portion 2.
The holder 1 body can be fixed to the ground or a pipe. The peg portion 5 is configured by connecting a tip portion 5a and a plurality of columnar portions having different sizes to each other. Specifically, the plurality of columnar portions include a first columnar portion 5b,
It is composed of a second columnar part 5c and a third columnar part 5d, which are connected in this order. . The tip 5a is connected to the first column 5b, while the third column 5d is connected to the flat plate 3. In the present embodiment, the number of columnar portions is three, but the present invention is not limited to this.

The distal end portion 5a has a substantially inverted quadrangular pyramid shape as a whole, but in the vicinity of a connection portion with the first columnar portion 5b, two opposing side surfaces are recessed inside, and a horizontal cross section is formed. Are formed so as to have a substantially “H” shape. On the other hand, the first columnar portion 5b, the second columnar portion 5c, and the third columnar portion 5d each have a substantially square prism shape as a whole, except for the respective ends, similarly to the tip 5a. The two opposing side surfaces are recessed inside, and are formed so that the cross section in the horizontal direction is also substantially “H” shaped.

By forming the peg portion 5 with such a cross-sectional shape, when the peg portion 5 is inserted into the ground, the soil enters each recess, so that the holder 1 is stably fixed to the ground. At the same time, it becomes difficult for the holder 1 to accidentally come off the ground. Note that the overall shape and the cross-sectional shape of the peg portion 5 are merely examples, and are not limited to the above.

Further, the first columnar portion 5b, the second columnar portion 5c,

One of the columnar portion 5b, the second columnar portion 5c, and the third columnar portion 5d abuts on the inner surface of the pipe 6 at the ridge line, and the holder 1 is fixed to the pipe 6. Therefore, it is not necessary to use the holder 1 properly according to the inner diameter of the pipe 6 to which the holder 1 is fixed, and one holder 1 can cope with various pipes 6 having different inner diameters. Note that FIG. 3 shows a state in which the ridge line of the second columnar portion 5c is in contact with the inner surface of the pipe 6.

Next, a case where one of the watering tubes 20 and 30 is held by the holder 1 and the holder 1 is fixed to the ground will be described below.

When holding the irrigation tube 20 with the holder 1, as shown in FIGS. 6 and 7, a pair of ears 21 1
It is inserted into the grooves 2a. At this time, the irrigation tube 20 is flat because water has not been passed yet. Then, as shown in FIG. 8, the peg portion 5 is inserted into, for example, the ground 7 so that the ridges 36 can be irrigated, and the holder 1 is fixed to the ground 7. The holder 1 is inserted into a predetermined place on the ground 7 in advance, and then the watering tube 20 is inserted.
May be inserted into the first grooves 2a of the holder 1.

When water is passed through the irrigation tube 20 in this state, as shown in FIGS.

Water is sprayed at a predetermined angle from 22e ₂ (see FIG. 2A). At this time, the pair of ears 21 are formed in the first groove 2a.
2a, a part of the peripheral surface of the irrigation tube 20 is supported in contact with one end surface of the side walls 2d. 9 and 10 show perspective views of the irrigation tube 20 and the holder 1 during the passage of water. In particular, FIG. 9 shows the holding state of the irrigation tube 20 in the holder 1 in an easily understandable manner. 2 shows a perspective view of the irrigation tube 20 and the holder 1 when the irrigation tube 20 is cut off on the same plane as one end face of the holder 1.

When the predetermined watering by the watering tube 20 is completed, the water supply to the watering tube 20 is stopped, and the watering tube 20 becomes flat again. Therefore, by subsequently winding the irrigation tube 20, the irrigation tube 20 can be easily collected.

On the other hand, when the irrigation tube 30 is used in consideration of the irrigation range or the amount of irrigation, for example, as shown in FIGS. 12 and 13, a pair of ear-shaped portions 31 of the irrigation tube 30 are connected. The holder 1 is inserted into the second grooves 2b. At this time, the irrigation tube 30 is flat because water has not been passed yet. Then, as shown in FIG. 14, the peg portion 5 is inserted into the ground 7 so that the ridges 36 can be watered, and the holder 1 is fixed to the ground 7. In addition,
Insert the holder 1 in a predetermined place on the ground 7 in advance,
Thereafter, the irrigation tube 30 is connected to the second groove 2 b of the holder 1.
2b may be inserted.

When water is passed through the irrigation tube 30 in this state, as shown in FIGS. 15 to 17, the irrigation tube 30 expands and assumes a substantially cylindrical shape, and the irrigation hole 32a of the irrigation tube 30 is formed. ₁ , 32b ₁ , 32a ₂
Water is sprayed at a predetermined angle from 32b ₂ (see FIG. 2 (b)). At this time, the pair of ears 31 is formed in the second groove 2b.
2b, a part of the peripheral surface of the irrigation tube 30 comes into contact with the concave portion 2c and is surface-supported. FIGS. 15 and 16 show the irrigation tube 3 during water flow.
0 and the holder 1 are shown in perspective view, in particular in FIG.
Is a perspective view of the irrigation tube 30 and the holder 1 when the irrigation tube 30 is cut off on the same plane as one end face of the holder 1 in order to make the holding state of the irrigation tube 30 in the holder 1 easier to understand. FIG.

When the predetermined watering by the watering tube 30 is completed, the water supply to the watering tube 30 is stopped, and the watering tube 30 becomes flat again. Therefore, by subsequently winding the irrigation tube 30, the irrigation tube 30 can be easily collected.

As described above, the irrigation tubes 20 and 30
Is selected by the operator according to the irrigation range or the amount of irrigation, etc., but the holder 1 of the present embodiment has:
The first groove portions 2a and 2a and the second groove portions 2b and 2b are provided so that the selected tube can be reliably held regardless of which tube is selected. That is,
In the present embodiment, it is not necessary to use the holder 1 according to the size of the selected tube.

Therefore, regardless of the selection of the irrigation tubes 20 and 30, the same holder 1 can be used by the operator, and the workability in the irrigation operation can be improved as compared with the conventional case. In addition, since various tubes can be held by one holder 1, the number of holders 1 can be reduced as compared with a case where holders corresponding to respective tubes are formed one by one.

When the holder 1 of this embodiment is used, a pair of ears 21 of the irrigation tube 20 are used.
Is simply inserted through the first grooves 2a or 2a, and is removed from the first grooves 2a and 2a, and it is not necessary to perform a complicated attaching and detaching operation of the tube using the pressing member as in the related art. Therefore, also from such a viewpoint, the workability in the watering operation can be improved. Also, there is no need to separately provide a pressing member as described above, and
Since the holder 1 can be obtained by integral molding using a mold or the like, the manufacturing cost and price of the holder 1 can be reduced.

In addition, the above-mentioned conventional holding member is usually made of rubber or plastic having elasticity and elasticity, so that it has poor weather resistance. Therefore, when the holder having the above-described holding member is used particularly in an open field, the holding member is easily deteriorated, and the life of the holding member is shortened.

However, since the holding member 1 of the present embodiment does not use such a holding member having poor light resistance, the holding member 1 can be used relatively longer than a conventional holding member having a holding member.

Note that the holder 1 is, for example, 150c
m at a distance of about 2 m.
0.30 is not twisted by water pressure or the like at the time of passing water, and does not droop drastically between the holders 1.1. This is because the irrigation tubes 20 and 30 are made of a pair of ear-shaped portions 21 and 21 or ear-shaped portions 31.3 that have been heat-sealed or the like.
1 are provided in the length direction and have appropriate rigidity, and the irrigation tube 20 further includes convex portions 23 extending along the length direction. Because it is. Therefore, at the time of water supply, the watering angle is maintained almost accurately over the entire irrigation tubes 20 and 30.

When the cultivated plants 35 planted on the ridges 36 are, for example, green onions, the height of the green onions sharply increases as they grow. Therefore, while the holder 1 is fixed to the ground 7, it is impossible to irrigate the ridges 36 farther away due to the leek in the vicinity.

In such a case, as shown in FIG. 18, for example, the irrigation tube 20 is held by the holder 1, and the holder 1 is connected to a pipe corresponding to the height of the cultivated plant 35. 6 may be fixed. Thereby, the installation height of the irrigation tube 20 is increased.
Can be set appropriately according to the height of the cultivated plant 3
The desired irrigation can be performed irrespective of the type and height of 5 ... Further, since the holder 1 has the peg portions 5 having widths corresponding to the inner diameters of various pipes, it is not necessary to use the holders 1 according to the inner diameter of the pipe 6, and one holder 1 is sufficient. Can be handled.

In this embodiment, the irrigation tube 2
The holder 1 for holding either one of the first and second grooves 0a and 30 has been described. However, as shown in FIG.
· Holder 1 with an increased distance between 2a and second grooves 2b
May be configured.

In this case, since the irrigation operation can be performed by using the irrigation tubes 20 and 30 together, it is very effective in increasing the amount of irrigation. If both of the irrigation tubes 20 and 30 are always held by the holding section 2, desired irrigation can be performed at any time only by passing water through one of them. Further, in this case, it is not necessary to attach and detach the irrigation tubes 20 and 30 to and from the holder 1 each time water is supplied or not. Therefore, workability during watering can be further improved.

If the irrigation tubes 20 and 30 are held by the holder 1 at a time, for example, one of them can be used for watering, or the other can be used for watering. The watering method can be selected according to watering conditions such as watering amount, watering range and the like. as a result,
Irrigation work according to the irrigation conditions can be performed accurately.

In the holder 1 of this embodiment,
A concave portion 2c having a substantially arc-shaped cross section is formed along the lower peripheral surface of the irrigation tube 30, and the peripheral surface is supported by the concave portion 2c. However, the cross section is not limited to the substantially arc shape.

For example, as shown in FIG. 20, the lower peripheral surface of the irrigation tube 30 is supported at two points by the concave portion 2c.
The cross section of the concave portion 2c may be formed in a substantially home base shape or a substantially V shape. Also, as shown in FIG.
The supporting surface of the irrigation tube 30 in the concave portion 2c may be formed horizontally so that the lower peripheral surface of the irrigation tube 30 is supported at one point at c. Even in the shape of the recess 2c as shown in FIGS. 20 and 21, the irrigation tube 30 can be stably held by the second grooves 2b, 2b and the recess 2c.

As shown in FIG. 22, the recess 2c may be formed so as not to contact the lower peripheral surface of the irrigation tube 30. In this case, although the peripheral surface of the irrigation tube 30 is not supported by the concave portion 2c, the pair of second groove portions 2b
Since the pair of ear-shaped portions 31 are securely supported by the, the irrigation tube 30 is surely held by the holder 1.

As described above, the holder for the irrigation tube according to the first aspect of the present invention has a pair of ear-like portions extending along the length direction and a plurality of irrigation tubes extending in the length direction. It is a holder for an irrigation tube for holding an irrigation tube having a perforated hole, wherein a pair of groove-shaped support portions through which the pair of ear-shaped portions are inserted are provided according to the type of the irrigation tube. A plurality of ear-shaped portions are provided and supported by supporting portions corresponding to the ear-shaped portions to hold a watering tube having the ear-shaped portions.

Therefore, since a single holder is provided with a plurality of groove-shaped support portions according to the type of irrigation tube, it is not necessary to use different holders according to the irrigation tube to be used. . As a result, it is possible to hold and fix a plurality of types of irrigation tubes with a single holder.

When holding the irrigation tube,
It is only necessary to insert the ear-shaped part of the irrigation tube through the support. Conversely, when removing the irrigation tube from the holder, the irrigation tube need only be withdrawn from the support.

As described above, according to the above configuration, there is an effect that the workability in the watering operation can be improved. Further, since there is no need to separately provide a pressing member for attaching the irrigation tube to the holder, the number of parts can be reduced, and the manufacturing cost and price of the holder can be reduced.

According to a second aspect of the present invention, in addition to the structure of the first aspect, the holder for the irrigation tube according to the second aspect of the present invention further includes an insertion portion inserted into the ground or a pipe for fixing the holder. The insertion portion has a configuration in which at least a plurality of columnar portions having different sizes are connected, and the width of each columnar portion is a width corresponding to the inner diameter of various pipes.

Therefore, in addition to the effect of the configuration of claim 1, it is not necessary to use different holders according to the inner diameter of the pipe to which the holder is fixed, and one holder can be used for various pipes having different inner diameters. This has the effect of being able to respond.

According to the third aspect of the present invention, as described above, in addition to the configuration of the first or second aspect, the holder for the irrigation tube is in contact with a part of the peripheral surface of the held irrigation tube. This is a configuration further including a unit.

Therefore, an effect that the irrigation tube can be held more stably as compared with the case where only a pair of ear-shaped portions is supported is exerted.
