以下、本発明に係る苗木等保護具について、添付の図面に基づいて詳しく説明する。なお、以下に説明する実施形態は、本発明を実施するに好ましい具体例であるから、技術的に種々の限定がなされているが、本発明は、以下の説明において特に発明を限定する旨が明記されていない限り、この形態に限定されるものではない。また、図１における上側が上方、下側が下方に相当する。 Hereinafter, the protective equipment such as seedlings according to the present invention will be described in detail with reference to the attached drawings. Since the embodiments described below are specific examples preferable for carrying out the present invention, various technical restrictions are made, but the present invention is intended to particularly limit the invention in the following description. Unless otherwise stated, it is not limited to this form. Further, the upper side in FIG. 1 corresponds to the upper side and the lower side corresponds to the lower side.

苗木等保護具１は、山の傾斜面などに設置され、苗木２の外周を縦長筒状の保護ネット１０で覆うことによって、シカ、イノシシ、ウサギ、ネズミなどの野生動物から苗木２を護り、新芽、葉、樹皮などを食す野生動物の食害から苗木等を保護する装置である。そして、図１から図４に示すように、本実施形態の苗木等保護具１は、主として、保護ネット１０と、支柱２０と、係止部材３０を備える。 The sapling protection device 1 is installed on a slope of a mountain or the like, and protects the sapling 2 from wild animals such as deer, wild boar, rabbit, and rat by covering the outer circumference of the sapling 2 with a vertically long tubular protective net 10. It is a device that protects seedlings from the feeding damage of wild animals that eat sprouts, leaves, bark, etc. Then, as shown in FIGS. 1 to 4, the protective tool 1 for seedlings and the like of the present embodiment mainly includes a protective net 10, a support column 20, and a locking member 30.

保護ネット１０は、縦長筒形状であり、上端部１１と下端部１２を有する。上端部１１と下端部１２は開口している。第一側端部１６と第二側端部１７は保護ネット１０の中心軸を挟んで略平行に形成されている。上端部１１は、保護ネット１０の長手方向に対して、支柱２０によって支持される第一側端部１６から保護ネット１０の中心軸を挟んで反対側の第二側端部１７に向かって、斜め下方に延びる。したがって、上端部１１が斜めにカットされた部分については保護ネット１０を軽量に形成できるため、保護ネット１０を１本の支柱２０によって支持することができる。また、苗木２が成長した場合に、上端部１１は斜めにカットされているため開口しやすく、苗木２の成長を妨げることを防ぐことができる。 The protective net 10 has a vertically long tubular shape and has an upper end portion 11 and a lower end portion 12. The upper end 11 and the lower end 12 are open. The first side end portion 16 and the second side end portion 17 are formed substantially parallel to each other with the central axis of the protective net 10 interposed therebetween. The upper end portion 11 faces the second side end portion 17 on the opposite side of the central axis of the protection net 10 from the first side end portion 16 supported by the support column 20 in the longitudinal direction of the protection net 10. It extends diagonally downward. Therefore, since the protective net 10 can be formed lightweight for the portion where the upper end portion 11 is cut diagonally, the protective net 10 can be supported by one support column 20. Further, when the seedling 2 grows, the upper end portion 11 is cut diagonally so that it can be easily opened, and it is possible to prevent the seedling 2 from being hindered from growing.

保護ネット１０の下端部１２は、上端部１１と略平行に形成されている。保護ネット１０の下端部１２は、上端部１１と同様に、保護ネット１０の長手方向に対して斜めに交差しているため、山の傾斜面に苗木を植える場合、傾斜面の角度に沿わせて苗木等保護具１を設置することができる。つまり、山の傾斜面に合わせて苗木等保護具１を設置することができるため、保護ネット１０と地面との間に隙間が生じず、野生動物が隙間を利用して苗木等保護具１を破壊して苗木を食したり、うさぎやネズミなどの小動物が隙間から苗木等保護具１の内部に侵入して苗木を食すことを防ぐことができる。 The lower end portion 12 of the protective net 10 is formed substantially parallel to the upper end portion 11. Since the lower end portion 12 of the protective net 10 intersects the upper end portion 11 at an angle with respect to the longitudinal direction of the protective net 10, when saplings are planted on the inclined surface of the mountain, the lower end portion 12 is aligned with the angle of the inclined surface. Protective equipment 1 such as seedlings can be installed. That is, since the protective equipment 1 such as seedlings can be installed according to the slope of the mountain, there is no gap between the protective net 10 and the ground, and wild animals can use the gap to install the protective equipment 1 such as seedlings. It is possible to prevent small animals such as rabbits and mice from invading the inside of the protective device 1 such as seedlings through a gap and eating the seedlings by destroying them and eating the seedlings.

保護ネット１０の下端部１２は、本実施形態において、上端部１１と略平行に形成されているが、図５に示すように、第二実施形態において、保護ネット１０の中心軸に対して垂直な方向に形成されてもよい。具体的には、苗木を植える場所が平坦な土地である場合、下端部１２も平坦であると保護ネット１０を取り付けやすく、作業効率も良い。 The lower end portion 12 of the protective net 10 is formed substantially parallel to the upper end portion 11 in the present embodiment, but as shown in FIG. 5, in the second embodiment, it is perpendicular to the central axis of the protective net 10. It may be formed in any direction. Specifically, when the place where the seedlings are planted is a flat land, if the lower end portion 12 is also flat, the protective net 10 can be easily attached and the work efficiency is good.

保護ネット１０は、網目を有するラッセル編みによって成形されていることが好ましい。保護ネット１０の編み方は、本目網など種々の編み方の中でも、結節部がなく強度の高いラッセル編みが好ましい。保護ネット１０の網目の大きさは、０．５〜５ｍｍが好ましく、２〜４ｍｍがさらに好ましいが、日光を遮りすぎない程度で、また、干ばつや強光による被害を防ぐことができれば本実施形態の数値に限定されない。 The protective net 10 is preferably formed by Russell knitting having a mesh. Among various knitting methods such as a main mesh, the protective net 10 is preferably knitted by Russell knitting having no knots and high strength. The mesh size of the protective net 10 is preferably 0.5 to 5 mm, more preferably 2 to 4 mm, but the present embodiment is provided as long as it does not block too much sunlight and can prevent damage caused by drought or strong light. It is not limited to the numerical value of.

保護ネット１０は、内側面１３と外側面１４を有する。苗木２を囲うように保護ネット１０を設置した場合に、内側面１３は苗木２に面する内部側であり、外側面１４は保護ネット１０の外部側である。上述したように、保護ネット１０は編み物であることから表裏の両面の粗さの違いがあり、より平滑な面が内側に位置するように配している。すなわち、内側面１３は外側面１４よりも平滑に形成されている。このため、苗木２の枝葉が成長して内側面１３に接触しても抵抗が少ないので、苗木が成長したときに枝などが滑りやすく網目から突き出ることを防ぐことができる。 The protective net 10 has an inner surface 13 and an outer surface 14. When the protective net 10 is installed so as to surround the sapling 2, the inner side surface 13 is the inner side facing the sapling 2, and the outer side surface 14 is the outer side of the protective net 10. As described above, since the protective net 10 is knitted, there is a difference in roughness on both the front and back surfaces, and the protective net 10 is arranged so that the smoother surface is located inside. That is, the inner surface 13 is formed smoother than the outer surface 14. Therefore, even if the branches and leaves of the seedling 2 grow and come into contact with the inner side surface 13, there is little resistance, so that when the seedling grows, the branches and the like are slippery and can be prevented from protruding from the mesh.

保護ネット１０は、図３に示すように、保護ネット１０の長手方向に対して垂直方向に延びる係止孔１５を有する。係止孔１５は、第一側端部１６における上端部１１近傍に形成されている。本実施形態において、係止孔１５は直線状の孔であるが、他の実施形態において、円形、楕円形、長方形などの形状の孔でもよい。また、係止孔１５を保護強化するため、例えば樹脂製からなる保護部材を係止孔１５の周縁に設けてもよい。 As shown in FIG. 3, the protective net 10 has a locking hole 15 extending in a direction perpendicular to the longitudinal direction of the protective net 10. The locking hole 15 is formed in the vicinity of the upper end portion 11 of the first side end portion 16. In the present embodiment, the locking hole 15 is a linear hole, but in other embodiments, it may be a hole having a shape such as a circle, an ellipse, or a rectangle. Further, in order to protect and strengthen the locking hole 15, for example, a protective member made of resin may be provided on the peripheral edge of the locking hole 15.

保護ネット１０の大きさは、保護ネット１０の中心軸方向、すなわち、図１における上下方向の長さが１５０ｃｍ〜１９０ｃｍが好ましい。これは、シカが苗木に届かない高さである。また、保護ネット１０の上端部１１および下端部１２を開口させ、円柱状に設置した場合の保護ネット１０の径は、２３ｃｍ〜２９ｃｍが好ましい。この大きさは、苗木が伸び伸びと育つ空間を保持するための径である。したがって、野生動物による苗木の食害が生じない程度に成長するまで苗木２を保護することができる。 The size of the protective net 10 is preferably 150 cm to 190 cm in the direction of the central axis of the protective net 10, that is, in the vertical direction in FIG. This is the height at which the deer cannot reach the saplings. Further, when the upper end portion 11 and the lower end portion 12 of the protective net 10 are opened and installed in a columnar shape, the diameter of the protective net 10 is preferably 23 cm to 29 cm. This size is the diameter for holding the space where the seedlings grow and grow. Therefore, the seedling 2 can be protected until it grows to the extent that the seedling is not damaged by wild animals.

図２に示すように、支柱２０は棒状であり、上端面２２は溝２１を有する。溝２１は、上方に開口した略コの字形状の横断面を有する。係止孔１５の周縁を上方より溝２１に案内し、係止孔１５に溝２１の両側の突出部分のうち一方を通すことで、保護ネット１０を支柱２０の上端面２２側に係止することができ、また、係止孔１５を上方へ持ち上げれば取り外すこともできる。このように、保護ネット１０は支柱２０に支持され、支柱２０に着脱可能に取り付けることができる。つまり、支柱２０は、保護ネット１０の内周側面であって第一側端部１６に沿って、保護ネット１０とともに係止部材３０により固定される。また、支柱２０の他端側である下部２３は、鋭角な形状を有しており地中に埋め込まれ、支柱２０が倒れないように固定される。 As shown in FIG. 2, the support column 20 has a rod shape, and the upper end surface 22 has a groove 21. The groove 21 has a substantially U-shaped cross section that opens upward. The protective net 10 is locked to the upper end surface 22 side of the support column 20 by guiding the peripheral edge of the locking hole 15 to the groove 21 from above and passing one of the protruding portions on both sides of the groove 21 through the locking hole 15. It can also be removed by lifting the locking hole 15 upward. In this way, the protective net 10 is supported by the support column 20 and can be detachably attached to the support column 20. That is, the support column 20 is fixed to the inner peripheral side surface of the protective net 10 along the first side end portion 16 by the locking member 30 together with the protective net 10. Further, the lower portion 23, which is the other end side of the support column 20, has an acute-angled shape and is embedded in the ground to prevent the support column 20 from falling over.

支柱２０は、安定性をよくするために、保護ネット１０を覆う部分以外は地中に埋め込まれる。したがって、支柱２０の長さは保護ネット１０よりも長い１９０ｃｍ〜２３０ｃｍであることが好ましい。また、支柱２０の材質は、ステンレスなどの非腐食性の高い金属、または軽量な樹脂などが好ましい。支柱２０は、山中では風雨にさらされるため耐久性に優れ、設置場所まで持ち運びが容易な軽量であることが好ましい。 The support column 20 is embedded in the ground except for the portion covering the protective net 10 in order to improve stability. Therefore, the length of the support column 20 is preferably 190 cm to 230 cm, which is longer than that of the protective net 10. The material of the support column 20 is preferably a highly non-corrosive metal such as stainless steel or a lightweight resin. Since the support column 20 is exposed to wind and rain in the mountains, it is preferable that the support column 20 is lightweight and easy to carry to the installation location.

図１、図２に示すように、係止部材３０は、支柱２０と嵌合して、保護ネット１０を支柱２０と挟み込んで係止する。具体的には、支柱２０を覆う保護ネット１０の上端部１１及び下端部１２において、係止部材３０が、支柱２０に嵌合するに際して、保護ネット１０を間に挟んで係止する。係止部材３０は、本実施形態において、断面が略U字状を有し、外面には弾力性を有する略U字状のバネ部材が取り付けられており、容易に保護ネット１０を支柱２０に嵌合することができる。支柱２０の数カ所に所定の間隔を空けて係止部材３０を取り付けることによって、苗木等保護具１を安定して設置することができる。係止部材３０は、取付け又は取外しを容易にすることができ、軽量なため山中へ持ち運ぶ部材として好適である。 As shown in FIGS. 1 and 2, the locking member 30 fits with the support column 20 and locks the protective net 10 by sandwiching it with the support column 20. Specifically, at the upper end 11 and the lower end 12 of the protective net 10 covering the support column 20, when the locking member 30 fits into the support column 20, the protective net 10 is sandwiched between the locking members 30 and locked. In the present embodiment, the locking member 30 has a substantially U-shaped cross section, and a substantially U-shaped spring member having elasticity is attached to the outer surface thereof, so that the protective net 10 can be easily attached to the support column 20. Can be fitted. By attaching the locking members 30 to several positions of the columns 20 at predetermined intervals, the protective equipment 1 such as seedlings can be stably installed. The locking member 30 can be easily attached or detached, and is lightweight, so that it is suitable as a member to be carried in the mountains.

杭４０は、図１、図４などに示すように、上部に略逆Ｌ字状の突起部４２を有する棒状であって、周面に上方上向きに突出した複数のくさび部４１を有する。杭４０は、保護ネット１０の下端部１２が口開きの状態になるように、下端部１２に杭４０を打ち込んで地面に固定させる。また、杭４０は、突起部４２が略逆Ｌの字状に形成されているため、保護ネット１０を突起部４２と当接させて地面に押し当てるようにして地面に埋設される。したがって、保護ネット１０の下端部１２がしっかりと地面に固定され、保護ネット１０と地面の間の隙間ができず、野生動物によって容易にめくり上げられることを防ぐことができる。本実施形態において、杭４０は２本使用しているが、２本以上でもよく、山の傾斜具合に応じて杭４０の使用数を調節することができる。 As shown in FIGS. 1 and 4, the pile 40 has a rod shape having a substantially inverted L-shaped protrusion 42 at the upper portion, and has a plurality of wedge portions 41 protruding upward and upward on the peripheral surface. The stake 40 is fixed to the ground by driving the stake 40 into the lower end 12 so that the lower end 12 of the protective net 10 is open. Further, since the protrusion 42 is formed in a substantially inverted L shape, the pile 40 is buried in the ground so that the protective net 10 is brought into contact with the protrusion 42 and pressed against the ground. Therefore, the lower end 12 of the protective net 10 is firmly fixed to the ground, and a gap between the protective net 10 and the ground is not formed, so that it can be prevented from being easily turned up by wild animals. In the present embodiment, two piles 40 are used, but two or more piles may be used, and the number of piles 40 used can be adjusted according to the inclination of the mountain.

くさび部４１は、杭４０が打ち込まれる方向に抗う方向に向かって突出して形成された平板状である。したがって、一旦地面に埋設された杭４０は容易に抜けることはなく、苗木等保護具１を設置しにくい山の傾斜面でも効果的に設置することができる。本実施形態において、突起部４２は略Ｌ字状であるが、他の実施形態において、杭４０から斜めに突出した棒状であってもよい。 The wedge portion 41 has a flat plate shape formed so as to project in a direction opposite to the direction in which the pile 40 is driven. Therefore, the pile 40 once buried in the ground does not easily come off, and can be effectively installed even on a mountain slope where it is difficult to install the protective equipment 1 such as seedlings. In the present embodiment, the protrusion 42 is substantially L-shaped, but in other embodiments, the protrusion 42 may be rod-shaped diagonally protruding from the pile 40.

杭４０の長さは、支柱２０の長さから保護ネット１０の長さを差し引いた長さ程度、つまり、２５ｃｍ〜３５ｃｍであることが好ましい。杭４０の材質は、地中で錆びにくい金属製、または軽い樹脂製が好ましい。 The length of the pile 40 is preferably about the length obtained by subtracting the length of the protective net 10 from the length of the support column 20, that is, 25 cm to 35 cm. The material of the pile 40 is preferably a metal that does not easily rust in the ground or a light resin.

以上、図１〜図４を参照して説明したように、本実施形態の苗木等保護具１によれば、苗木等保護具の構成部材を簡素化することによって、人力で運搬せざるを得ないような場所であっても多くの苗木保護具を苗木の植樹場所まで持ち運び易くすることができるとともに、生産コストや、設置の労力を大幅に削減することができ、設置時間も短縮することができるため資材代や人件費を大幅に削減することができる。 As described above with reference to FIGS. 1 to 4, according to the sapling or the like protective tool 1 of the present embodiment, by simplifying the constituent members of the sapling or the like protective device, the sapling or the like must be transported manually. It is possible to easily carry many sapling protectors to the sapling planting place even in places where there is no such thing, and it is possible to significantly reduce production costs and installation labor, and shorten the installation time. As a result, material costs and labor costs can be significantly reduced.
