Abstract

<P>PROBLEM TO BE SOLVED: To provide a crop cap facilitating watering work, and to provide a cap fixing skewer hard to come off from a seedling bed, and fixing the crop cap to a seedling bed so as not to be blown off by a wind. <P>SOLUTION: This crop cap 10 is obtained by unitedly forming a peripheral wall surface 11 with a cross section of a nearly circular shape, and a ceiling plane 12 continuing from the upper end of the peripheral wall surface 11, in a dome form by a translucent plastic material, and forming a vent hole 12a on the ceiling plane 12. The vent hole 12a is formed near the top of the ceiling plane 12, and the peripheral wall surface 11 and the ceiling plane 12 are formed to continue to each other through a bending part 14. The ceiling plane 12 becomes a recessed form by pushing the central part of the ceiling plane 12 of a projecting form into the inside, and the ceiling plane 12 becomes a projecting form by pushing the central part of the ceiling plane 12 of a recessed form into the outside. Since a projecting part 21c of a skewer piece 21a driven into a seedling bed 22 is caught in soil of the seedling bed 22, dried and hardened after watering or rainfall, the crop caps 10 and 10A are free from coming off from the seedling bed even when a wind pressure acts thereon. <P>COPYRIGHT: (C)2012,JPO&INPIT

作物用キャップを被せた苗に水遣りする際、ドーム型の天井面に多数の小径通気穴を形成した作物用キャップの場合、キャップ固定串を抜いて一々、作物用キャップを地面から取り外さなければならず、水遣り作業が煩わしい。一方、天井面に比較的径の大きな通気穴を形成した作物用キャップの場合、作物用キャップを地面から取り外さずに、ホースを通気穴に通して水遣りできる。しかしながら、多数の苗に水遣りする場合、多数の作物用キャップの通気穴に一々ホースを通さなければならず、やはり水遣り作業が煩わしい。
本発明はかかる問題点に鑑み、水遣り作業が容易な作物用キャップを提供することを目的とする。 When watering seedlings with crop caps, in the case of crop caps with many small-diameter ventilation holes on the dome-shaped ceiling, the cap caps must be pulled out and removed from the ground one by one. The watering work is troublesome. On the other hand, in the case of a crop cap in which a vent hole having a relatively large diameter is formed on the ceiling surface, the hose can be passed through the vent hole and watered without removing the crop cap from the ground. However, when watering a large number of seedlings, it is necessary to pass a hose through the ventilation holes of a large number of crop caps.
The present invention has been made in view of such problems, and an object thereof is to provide a cap for crops that facilitates watering work.

請求項１に記載の発明は、横断面形状が略円形の周壁面と、周壁面の上端部から連続する天井面とを透光性プラスチック材料でドーム型に一体成形し、天井面に通気穴を形成した作物用キャップであって、
天井面の頂部近辺に通気穴を形成し、
周壁面と天井面が屈曲部を介して連続するように形成し、
屈曲部の屈曲変形により天井面全体が外側へ湾曲して膨出する凸形態と、内側へ湾曲して窪む凹形態の何れか一方の形態に択一的に保持され、
かつ凸形態の天井面の中央部を内側へ押し込むと天井面が凹形態となり、凹形態の天井面の中央部を外側へ押し込むと天井面が凸形態となるように構成したことを特徴とする。 According to the first aspect of the present invention, a peripheral wall surface having a substantially circular cross-sectional shape and a ceiling surface continuous from the upper end portion of the peripheral wall surface are integrally formed into a dome shape with a translucent plastic material, and a ventilation hole is formed in the ceiling surface. A cap for crops,
Form a vent hole near the top of the ceiling surface,
The peripheral wall surface and the ceiling surface are formed so as to be continuous through the bent part,
It is alternatively held in one of a convex form in which the entire ceiling surface is curved outward and bulges by a bending deformation of the bent part, and a concave form that is curved inward and recessed,
In addition, when the center portion of the convex ceiling surface is pushed inward, the ceiling surface becomes concave, and when the central portion of the concave ceiling surface is pushed outward, the ceiling surface becomes convex. .

請求項１に係る発明によれば、ドーム型の作物用キャップの天井面を内側へ湾曲して窪む凹形態にすると、天井面が水の受け皿となり、かつ天井面の頂部近辺に形成した通気穴が導水穴となる。そのため、ホースを通気穴に通さなくても天井面にホースから水を注げば通気穴を通って作物用キャップの内部に流入し、苗に水が注がれる。また、天井面に降った雨水も通気穴から効率的に作物用キャップの内部に流入するので、水遣り作業が容易になる。
また、凹形態の天井面に小石等の重石を載せれば、強風時に作物用キャップが吹き飛ばされるのを防止できる。
一方、天井面を凸形態にすれば、地面から天井面までの高さが増大するので、苗の生育に伴い新芽が天井に接触して生育不良となるのを可及的に遅くできる。また、枯れ草等のゴミが天井面に滞留して透光性が低下するのを防止できる。 According to the first aspect of the present invention, when the ceiling surface of the dome-shaped crop cap is concaved to be curved inwardly, the ceiling surface serves as a water tray, and the ventilation formed near the top of the ceiling surface. The hole becomes a water conduction hole. Therefore, if water is poured from the hose to the ceiling surface without passing the hose through the ventilation hole, it flows into the crop cap through the ventilation hole, and water is poured into the seedling. In addition, rainwater that has fallen on the ceiling surface efficiently flows into the crop cap from the vent hole, facilitating watering work.
Moreover, if a heavy stone such as a pebble is placed on the concave ceiling surface, it is possible to prevent the crop cap from being blown off during a strong wind.
On the other hand, if the ceiling surface has a convex shape, the height from the ground to the ceiling surface increases, so that it is possible to slow down as soon as possible that new shoots come into contact with the ceiling and become poorly grown as seedlings grow. In addition, it is possible to prevent dirt such as dead grass from staying on the ceiling surface and reducing the translucency.

以下に本発明を図面に基づき説明するに、図１〜図３には本発明の第１実施例に係る作物用キャップ１０が示されている。当該作物用キャップ１０は横断面形状が略円形の周壁面１１と、周壁面１１の上端部から連続し、湾曲して外側に膨出する天井面１２と、周壁面１１の下端部に形成したフランジ部１３から成り、周壁面１１、天井面１２、フランジ部１３はポリ塩化ビニル、ポリプロピレン等の透光性プラスチック材料でドーム型に一体成形されている。 Hereinafter, the present invention will be described with reference to the drawings. FIGS. 1 to 3 show a crop cap 10 according to a first embodiment of the present invention. The crop cap 10 is formed on a peripheral wall surface 11 having a substantially circular cross-sectional shape, a ceiling surface 12 which is continuous from the upper end portion of the peripheral wall surface 11 and is curved and bulges outward, and a lower end portion of the peripheral wall surface 11. It consists of a flange portion 13, and the peripheral wall surface 11, the ceiling surface 12, and the flange portion 13 are integrally formed in a dome shape with a light-transmitting plastic material such as polyvinyl chloride or polypropylene.

周壁面は複数本の環状の段差面１１ａが形成されている。各段差面１１ａは上下方向に積層され、周壁面１１の下端部側の段差面１１ａから上端部側の段差面１１ａへと各段差面１１ａの径が漸減しているので、周壁面１１は全体として、上部側ほど径が縮小した円筒形状を備えている。 A plurality of annular step surfaces 11a are formed on the peripheral wall surface. Each step surface 11a is laminated in the vertical direction, and the diameter of each step surface 11a gradually decreases from the step surface 11a on the lower end side of the peripheral wall surface 11 to the step surface 11a on the upper end side. As shown in FIG. 2, the upper side has a cylindrical shape with a reduced diameter.

天井面１２は周壁面１１の上端部から連続し、外側へ緩やかに湾曲して膨出した凸形態を備えている。そして、周壁面１１と天井面１２との境界部分が屈曲部１４として形成され、周壁面１１と天井面１２が直角より若干大きな角度、本実施例では凸形態のとき約１００度の角度を形成している。天井面１２の頂部には１個の通気穴１２ａが形成され、通気穴１２ａの周囲に断面半円形の環状リブ１２ｂが形成されている。 The ceiling surface 12 is continuous from the upper end portion of the peripheral wall surface 11 and has a convex shape that gently curves and bulges outward. The boundary portion between the peripheral wall surface 11 and the ceiling surface 12 is formed as a bent portion 14, and the peripheral wall surface 11 and the ceiling surface 12 form an angle slightly larger than a right angle, in this embodiment, an angle of about 100 degrees when convex. doing. One ventilation hole 12a is formed at the top of the ceiling surface 12, and an annular rib 12b having a semicircular cross section is formed around the ventilation hole 12a.

フランジ部１３は周壁面１１の下端開口面１１ｂの外周に沿って形成されている。フランジ部１３には２本の環状リブ１３ａ，１３ｂが形成され、環状リブ１３ａ，１３ｂの間に通気穴１２ｂを中心として等角度間隔で串穴１３ｃが形成されている。 The flange portion 13 is formed along the outer periphery of the lower end opening surface 11 b of the peripheral wall surface 11. Two annular ribs 13a and 13b are formed in the flange portion 13, and skewer holes 13c are formed between the annular ribs 13a and 13b at equiangular intervals with the vent hole 12b as a center.

本実施例に係る作物用キャップ１０の構造は以上の通りであって、図２に示すように苗２０にこの作物用キャップ１０を被せ、フランジ部１３の串穴１３ｃにキャップ固定串２１を通して苗床２２の土に差し込み、作物用キャップ１０を苗床２２に固定する。 The structure of the crop cap 10 according to the present embodiment is as described above. As shown in FIG. 2, the crop cap 10 is put on the seedling 20, and the nursery bed is passed through the cap fixing skewer 21 in the skewer hole 13 c of the flange portion 13. 22 and the crop cap 10 is fixed to the nursery 22.

図４にキャップ固定串２１の詳細を図示する。キャップ固定串２１の材料には針金が使用され、針金を曲げ加工して、２本の串片２１ａと両串片２１ａの上端部を連結する押さえ片２１ｂからなる二股形状に成形されている。そして、両方の串片２１ａの下端部近辺にプレス成型により長方形の凸部２１ｃが形成されている。作物用キャップ１０は、一方の串片２１ａを串穴１３ｃを通して苗床２２に打ち込み、押さえ片２１ｂでフランジ部１３を苗床２２に押さえ着けて苗床２２に固定される。 FIG. 4 shows details of the cap fixing skewer 21. A wire is used as the material of the cap fixing skewer 21, and the wire is bent and formed into a bifurcated shape including two skewer pieces 21a and a pressing piece 21b connecting the upper ends of both skewer pieces 21a. And the rectangular convex part 21c is formed by press molding in the vicinity of the lower end part of both skewer pieces 21a. The crop cap 10 is fixed to the nursery bed 22 by driving one skewer piece 21a into the nursery bed 22 through the skewer hole 13c and pressing the flange portion 13 against the nursery bed 22 with the holding piece 21b.

水遣りを行う場合、作物用キャップ１０の天井面１２の中央部を指で内側へ押し込む。図１に想像線で示すように、屈曲部と天井面１２と周壁面１１が成す角度が約９０度を越えるまで屈曲部１４が屈曲すると、凸形態を保持していた天井部は図３に示すように、内側へ緩やかに湾曲して窪む凹形態となり、凹形態が保持される。このとき屈曲部１４は全周にわたって一平面Ｐに接する。そこで、ホースから凹形態となった天井面１２に水を注ぐと、水が通気穴１２ａを通って作物用キャップ１０の内部に流入し、苗２０の根元に浸透する。 When watering, the center of the ceiling surface 12 of the crop cap 10 is pushed inward with a finger. As shown by an imaginary line in FIG. 1, when the bent portion 14 is bent until the angle formed by the bent portion, the ceiling surface 12, and the peripheral wall surface 11 exceeds about 90 degrees, the ceiling portion maintaining the convex shape is shown in FIG. 3. As shown, it becomes a concave shape that is gently curved inward and recessed, and the concave shape is maintained. At this time, the bent portion 14 is in contact with one plane P over the entire circumference. Therefore, when water is poured from the hose into the concave ceiling surface 12, the water flows into the inside of the crop cap 10 through the vent hole 12 a and penetrates into the roots of the seedlings 20.

本実施例に係る作物用キャップ１０によれば、ドーム型の天井面１２を内側へ湾曲して窪む凹形態にすると、天井面１２が水の受け皿となり、かつ天井面１２の頂部に形成した通気穴１２ａが導水穴となる。そのため、ホースを通気穴１２ａに通さなくても天井面１２にホースから水を注げば通気穴１２ａを通って作物用キャップ１０の内部に水が流入し、苗２０に注がれる。また、天井面１２に降った雨水も通気穴１２ａから効率的に作物用キャップ１０の内部に流入するので、水遣り作業が容易になる。 According to the crop cap 10 according to the present embodiment, when the dome-shaped ceiling surface 12 has a concave shape that curves inward and is recessed, the ceiling surface 12 becomes a water tray and is formed at the top of the ceiling surface 12. The vent hole 12a becomes a water guide hole. Therefore, if water is poured from the hose into the ceiling surface 12 without passing the hose through the vent hole 12a, the water flows into the crop cap 10 through the vent hole 12a and is poured into the seedling 20. In addition, since rainwater that has fallen on the ceiling surface 12 efficiently flows into the crop cap 10 from the vent hole 12a, the watering operation is facilitated.

また、凹形態の天井面１２に小石等の重石を載せれば、強風時に作物用キャップ１０が吹き飛ばされるのを防止することもできる。 Further, if a heavy stone such as a pebbles is placed on the concave ceiling surface 12, it is possible to prevent the crop cap 10 from being blown off in a strong wind.

一方、通気穴１２ａに指を入れて凹形態の天井面の中央部を外側へ引き上げると（外側へ押し込むと）天井面が図２に示す凸形態となってこの凸形態が保持される。天井面１２を図２に示す凸形態にすれば、地面から天井面１２までの高さが増大するので、苗２０の生育に伴い新芽が天井面１２に接触して生育不良となるのを可及的に遅くできる。また、枯れ草等のゴミが天井面の表面に滞留して透光性が低下するのを防止できる。 On the other hand, when the finger is put into the vent hole 12a and the central portion of the concave ceiling surface is pulled outward (pressed outward), the ceiling surface becomes the convex shape shown in FIG. 2, and this convex shape is maintained. If the ceiling surface 12 has the convex shape shown in FIG. 2, the height from the ground to the ceiling surface 12 increases, so that it is possible for the shoots to come into contact with the ceiling surface 12 and cause poor growth as the seedlings 20 grow. Can be as late as possible. Further, it is possible to prevent dust such as dead grass from staying on the surface of the ceiling surface and reducing the translucency.

また、本実施例に係るキャップ固定串２１によれば、作物用キャップ１０に風圧が作用しても、苗床２２に打ち込んだ串片２１ａの凸部２１ｃが、水遣りや降雨の後に乾燥して固まった苗床２２の土に引っ掛かるため、苗床２２から抜け難い。そのため、作物用キャップ１０を風に吹き飛ばされないように苗床２２に固定できる。 Further, according to the cap fixing skewer 21 according to the present embodiment, even if wind pressure acts on the crop cap 10, the convex portion 21c of the skewer piece 21a driven into the seedbed 22 is dried and solidified after watering or raining. Since it is caught in the soil of the seedbed 22, it is difficult to come out of the seedbed 22. Therefore, the crop cap 10 can be fixed to the seedbed 22 so as not to be blown away by the wind.

さらにまた、本実施例に係るキャップ固定串２１は、材質に針金を使用するので、プレス成型で簡単に凸部２１ｃを加工でき、加工コストを低減できる。
なお、本実施例に係るキャップ固定串２１では、長方形の凸部２１ｃを串変２１ａに各１個形成したが、複数個形成すれば、よりキャップ固定串が抜け難くなる。また、材質として、針金の曲げ加工の他、鉄板から打ち抜き加工したり、硬質プラスチックで成型することも可能である。 Furthermore, since the cap fixing skewer 21 according to the present embodiment uses a wire as the material, the convex portion 21c can be easily processed by press molding, and the processing cost can be reduced.
In the cap fixing skewer 21 according to the present embodiment, one rectangular convex portion 21c is formed on each skewer 21a. However, if a plurality of rectangular protruding portions 21c are formed, the cap fixing skewer is more difficult to be removed. In addition to wire bending, the material can be punched from an iron plate or molded from hard plastic.

本発明の第２実施例に係る作物用キャップを図４に示す。第１実施例に係る作物用キャップ１０では天井面１２の頂部に１個の通気穴１２ａを形成したが、第２実施例に係る作物用キャップ１０Ａでは頂部近辺に多数の小径通気穴１２ｃが形成されている。
なお、第２実施例に係る作物用キャップ１０Ａの他の構成は第１実施例に係る作物用キャップ１０と同じであるので、同一の構成要素には同一の符号を付して説明を省略する。 A crop cap according to a second embodiment of the present invention is shown in FIG. In the crop cap 10 according to the first embodiment, one ventilation hole 12a is formed at the top of the ceiling surface 12. However, in the crop cap 10A according to the second embodiment, a large number of small-diameter ventilation holes 12c are formed near the top. Has been.
In addition, since the other structure of the crop cap 10A according to the second embodiment is the same as the crop cap 10 according to the first embodiment, the same components are denoted by the same reference numerals and description thereof is omitted. .

この作物用キャップ１０Ａを使用した場合も、図４に示すように天井面１２を凸形態にすることにより水遣りを容易にできる。 Even when this crop cap 10A is used, watering can be facilitated by making the ceiling surface 12 convex as shown in FIG.
