BACKGROUND ART Conventionally, in hoses for spraying powdered agricultural chemicals, etc., wear of the hose body that occurs when spraying the agricultural chemicals has been a problem. In particular, spraying hoses that have a conductive layer such as aluminum foil formed on the inner surface of the hose in order to prevent blocking of powdered agricultural chemicals due to electrostatic charging have a problem in that the aluminum foil peels off due to wear and the antistatic effect is lost. Therefore, in an attempt to prevent this wear, for example,
Technical means as described in Publication No. 1461 have been proposed.

したものである。 As shown in FIGS. 3 and 4, a conductive intermediate layer A3 such as aluminum foil is replaced with a highly wear-resistant synthetic resin film A1 such as nylon or polyester.
A three-layer structure sandwiched between an inner layer and an outer layer of a synthetic resin film A2 having good thermal fusion properties such as polypropylene or polyethylene is formed, and dispersion holes 1 are bored at predetermined intervals. Roll up this band-shaped body A with the inside layer, and overlap and heat-seal the edges of the outer layer as shown in Fig. 3, or as shown in Fig. 4.
A band-shaped bonded film C is heat-sealed so as to extend over opposite side edges by rolling it into a cylindrical shape.
このように、ホースを三層構造とし、しかも、
内側を耐摩耗性の大きい合成樹脂フイルムＡ１と
することにより、ホースの耐摩耗性はやや向上し
ているものの未だ十分でない。
In this way, the hose has a three-layer structure, and
Although the abrasion resistance of the hose is slightly improved by using synthetic resin film A1 with high abrasion resistance on the inside, it is still not sufficient.

しまうという問題がある。 In other words, wear progresses rapidly in the first part of the spray hole where the powdered pesticide passes through at high speed and turbulence is likely to occur.Especially, in hoses with a conductive layer such as aluminum foil in the middle layer, the wear progresses rapidly from the interface between each layer. There is a problem in that it often peels off and one part of the dispersion hole becomes tattered.
また、ホース本体２内が目視できず残留農薬等
の有無に確認も困難である。 Furthermore, the inside of the hose body 2 cannot be visually inspected, making it difficult to confirm the presence or absence of residual agricultural chemicals.
本考案は、このような問題点に鑑みなされたも

In the present invention, a transparent synthetic resin film A2 with good heat-sealing property provided on the inside and a transparent synthetic resin film A1 having a stronger strength than the synthetic resin film A2 are arranged around the dispersion hole 1. A three-layer hose body 2 is formed with a conductive intermediate layer A3 in between, and the spray holes 1 of this hose body 2 are
A transparent reinforcing film B was adhered to the inner peripheral part of the hose to form a spraying hose for powdered pesticides, etc.

する方が、筒状にする前に散布孔１を穿設でき、
製造しやすい。 Looking at the present invention more specifically, the hose main body 2 may be formed into a cylindrical shape from the beginning, but the synthetic resin film A is rolled up in the form of a belt, and the synthetic resin film A is thus made to face each other. A band-shaped bonded film C is formed by overlapping both longitudinal edges of the film A, or by straddling both longitudinal edges of the film A.
may be pasted and joined to form a cylindrical shape. By forming the belt-shaped synthetic resin film A into a cylindrical shape, the dispersion holes 1 can be drilled before forming the cylindrical shape.

た方がより好適である。 In this case, the bonded film C may be attached to the outside of the cylindrical hose body 2, but it is also possible to attach it from the inside. However, if it is pasted on the outside, there is a risk that obstacles, etc. may get caught on the edge of the bonded film C during spraying work such as pesticides, and the bonded film C may be peeled off from there, so it is better to paste it from the inside. More suitable.

電しない。 Furthermore, the conductive intermediate layer A3 includes an aluminum layer deposited on either the strong synthetic resin film A1 or the synthetic resin film A2 with good thermal adhesiveness, or a conductive material layer such as coated carbon. Alternatively, it may be a film containing carbon or the like.
Static electricity generated by friction with the air passing through the hose body 2 is grounded by this conductive intermediate layer A3, and no static electricity is generated.
また、前記散布孔１はランダムに穿設すること

所定間隔毎、例えば、等間隔毎、あるいは散布孔
１の開口面積が小から大となるように勾配を持た

まうおそれがあるので、内側から貼り付ける。 Furthermore, this reinforcing film B is pasted onto the hose body 2 from the inside. As in the case of bonded film C, if it is pasted from the outside, there is a risk that obstacles, etc. will get caught on the edge of reinforcing film B during spraying of pesticides, etc., and reinforcing film B may be peeled off from there. So, paste it from the inside.
また、散布孔１の周辺部分の導電中間層Ａ３を
削除しているので、この部分の各層の界面剥離が
生じにくくなる。 Further, since the conductive intermediate layer A3 in the area surrounding the dispersion hole 1 is removed, interfacial peeling of the layers in this area is less likely to occur.
そして、合成樹脂フイルムＡ１，Ａ２は透明

除してある。 A transparent nylon film A1 (thickness 15μ) is used as a film with high strength, and a transparent polypropylene film A2 (thickness 25μ) coated with aluminum is used as a film with good heat fusion bonding.The aluminum vapor deposition layer is a conductive intermediate layer. A three-layer belt-shaped synthetic resin film A is formed by stacking the films A3 in between. This three-layer belt-shaped synthetic resin film A has a conductive intermediate layer A3 at the center line portion in the longitudinal direction.
, and the conductive intermediate layer A3 on both longitudinal side edge portions are removed.

長手方向に沿つて等間隔に穿設されている。 Further, a reinforcing film B is pasted along the longitudinal direction of the belt-shaped synthetic resin film A on the polypropylene film A2 side by heat fusion, corresponding to the longitudinal center line portion where the conductive intermediate layer A3 has been removed. Reinforcement film B and the band-shaped synthetic resin film A
Spreading holes 1 are drilled through the belt-shaped synthetic resin film A at equal intervals along the longitudinal direction thereof.

ている。 Then, the belt-shaped synthetic resin film A is rolled up with the polypropylene film A2 side on the inside, and the longitudinal side edges of the belt-shaped synthetic resin film A, which are opposite to each other by rolling, are formed into a belt-shaped bonded film C that straddles these both side edges. to form a cylindrical hose body 2. This bonded film C is formed into four layers by sequentially stacking a polypropylene film C1 (thickness 25μ), a nylon film C2 (thickness 15μ), and an aluminum vapor-deposited polyester film C4 (thickness 12μ), with the aluminum vapor-deposited layer serving as a conductive intermediate layer C3. The polypropylene film C1 side is attached to the polypropylene film A2 of the band-shaped synthetic resin film A from the inside of the hose body 2 by heat fusion.

Ａ３を削除してあるが、この程度では帯電防止作
用に影響はない。 Static electricity generated by air friction during spraying is grounded through the conductive intermediate layer A3 of the hose body 2 and the conductive intermediate layer C3 forming the bonded film C, so that electrification is prevented and the powdered pesticide is transferred to the hose body. 2. There is no risk of it adhering to the inner walls, etc. Although the conductive intermediate layer A3 is partially removed from the hose body 2, this extent does not affect the antistatic effect.

接接着されているため、界面剥離しにくく散布孔
１部分から各フイルム層が剥がれてぼろぼろにな
ることがなく、強度が大きくなつた。 In addition, the conductive intermediate layer A3 is removed from the part of the hose body 2 where the spray hole 1 is formed, and the polypropylene film A2 and the nylon film A1 are directly bonded, making it difficult for the interface to peel off from the spray hole 1 portion. Each film layer did not peel off and become tattered, and the strength was increased.

面剥離しやすく、散布孔部分からホース本体が破
壊されるので、このように導電中間層Ａ３を部分
的に削除した利益は大きい。 If the conductive intermediate layer A3 is located in this area, since the conductive intermediate layer A3 is an aluminum layer, its adhesive strength with the polypropylene film A2 is weak, and therefore it is likely to peel off at the interface, and the hose body will be destroyed from the spray hole area. , the benefits of partially eliminating the conductive intermediate layer A3 in this way are great.
また、導電中間層Ａ３を散布孔１部分から削除
したことにより、この部分が透明なポリプロピレ

度はさらに大きくなる。 Furthermore, the reinforcing film B attached to the dispersion hole 1 portion is easy to heat-seal because the polypropylene film B1 forming the reinforcing film B and the polypropylene film A2 forming the hose body 2 are heat-sealed to each other. The adhesive strength after fusion is strong and it is difficult to peel off. Therefore, the strength of the one portion of the dispersion hole is further increased.
