Description
【０００１】[0001]
この考案は作物を植えた畦の両側に生える雑草を刈り取る除草機に関する。 The present invention relates to a weeder for cutting weeds growing on both sides of a ridge on which a crop is planted.
【０００２】[0002]
従来、作物を植えた畦の側面に生えた雑草、特に高さが５センチ以下程度の細 かな雑草を刈り取には柳刃式の刃を備えた除草機やロータリー刃を備えた除草機 を用いている。 Conventionally, weeds on the side of ridges on which crops are planted, especially fine weeds with a height of about 5 cm or less, are weeded with a willow blade or a weeder with a rotary blade. I am using.
【０００３】[0003]
柳刃式の刃を備える除草機は、刃によって土を押し上げ、掻き出す為に、刃を 土の中に深く差し込むと刃の側部から掻き出した土が作物の根本に寄り過ぎて埋 没する問題があり、よって刃を土に対して浅く適度に差し込む加減に気を使う必 要があった。 また、ロータリー刃を備えるものは、刃の回転で畦の間に生えた草を効率良く刈 り取ることができるが、刃の回転により作物の根を切断してしまうことがあり、 その為に作物の根元まで除草することが難しかった。 A weeder equipped with a willow blade type pushes up the soil with the blade and scrapes it out.Therefore, when the blade is inserted deeply into the soil, the soil scraped from the side of the blade gets too close to the root of the crop and is buried. Therefore, it was necessary to be careful in inserting the blade shallowly into the soil and appropriately inserting it. In addition, the one equipped with a rotary blade can efficiently mow the grass that has grown between the ridges by rotating the blade, but it sometimes cuts the root of the crop due to the rotation of the blade. It was difficult to weed the roots of crops.
【０００４】 本考案は、作物を植えた畦の側面に生える比較的細かな雑草を作物を傷めるこ となく且つ能率的に刈り取ることのできる草刈手段を提供することを目的とする 。An object of the present invention is to provide a mowing means capable of efficiently mowing relatively fine weeds growing on the side of a ridge where a crop is planted without damaging the crop.

上記した課題を解決する為に本考案の除草機は、自走車の前部若しくは後部に 複数の回転刃を取付支持し、自走車の走行に伴って上記回転刃により地面上の雑 草を刈り取る除草機であって、前記各回転刃は略円錐形若しくは円錐台形に形成 すると共にその外周面に沿って螺旋状の掻刃を突設して構成し、該回転刃を自走 車の幅方向に間隔をおいて複数個並設し、これら各回転刃を同刃の小径側端を走 行方向へ向けた状態で略水平に軸支すると共に、隣合う２個一対の回転刃同士を 所定の間隔をおいて平面視略ハ形に支持してなるものである。 In order to solve the above problems, the weeding machine of the present invention mounts and supports a plurality of rotary blades on the front or rear of a self-propelled vehicle, and the weeds on the ground are moved by the rotary blades as the self-propelled vehicle travels. In the weeding machine, the rotary blades are formed into a substantially conical shape or a truncated cone shape, and spiral scraping blades are provided so as to project along the outer peripheral surface of the rotary blades. Multiple rotary blades are arranged side by side in the width direction, and each rotary blade is supported substantially horizontally with the small-diameter side end of the blade facing in the running direction, and two adjacent rotary blades Is supported at a predetermined interval in a substantially C-shape in a plan view.
【０００６】[0006]
以上の手段によれば、円錐形若しくは円錐台形に形成される回転刃は２個一対 にして自走車の幅方向に所定の間隔、即ち作物が植えられる畦の幅に合わせた間 隔をおいて配設され、小径側の先端を走行方向前方へ向けた状態で回転自在に軸 支される。 ２個一対の回転刃同士は平面視において略ハ形に傾斜するように取り付けられ、 この両回転刃同士により上記した畦を両側から挟むと、両回転刃の側面が各々畦 の両側面の傾斜に沿って宛てがわれる。 そして、自走車の走行に伴って各回転刃を回転されると、該回転刃の周面に突設 した螺旋状の掻刃が回転し、畦の両側面に生える雑草を地表から適度な深さにて 掻き取り、掻き取った雑草と土とを上記螺旋刃に沿って移動させ回転刃大形側端 部から畦の外側へ向けて掻き出す。 According to the above-mentioned means, two rotary blades formed in a conical shape or a truncated cone shape are paired to have a predetermined interval in the width direction of the self-propelled vehicle, that is, an interval corresponding to the width of the ridge on which the crop is planted. And is rotatably supported with the tip of the small diameter side facing forward in the traveling direction. Two pairs of rotary blades are attached so as to incline into a substantially C shape in a plan view, and when the rotary ridges are sandwiched from both sides by the rotary blades, the side surfaces of both rotary blades are inclined on both sides of the ridge. Will be addressed. When each rotary blade is rotated along with the traveling of the self-propelled vehicle, the spiral scraping blade protruding on the peripheral surface of the rotary blade is rotated, and the weeds growing on both sides of the ridge are appropriately removed from the ground surface. Scraped at a depth, move the weeds and soil scraped along the spiral blade, and scrape out from the large side end of the rotary blade toward the outside of the ridge.
【０００７】[0007]
本考案は以上説明したようなものであるから、円錐形若しくは円錐台形に形成 した一対の回転刃が畦の両側面の形状に合わせて必然的に宛てがわれることにな り、また走行車の走行に伴って上記回転刃を回転させることにより螺旋状の掻刃 が畦の両側面の土を適度な深さで掻いて雑草と共に畦の外側へ向けて掻き出すこ とができる。 従って、従来のもののように畦の表面に対する刃の差し込み深さに気を使わずと も畦の両側面に対して回転刃が最適な状態で宛てがわれ、畦の側面を螺旋状の掻 刃により適度な深さで全面的に掻き取って作物の根本付近まで確実に且つ効率的 に除草することがてきる。また、上記した回転刃は畦の側面に宛てがわれた状態 で維持されるので、掻刃により畦の頂上部に植られる作物の根本を切断するよう な心配もない。 Since the present invention is as described above, a pair of conical or frustoconical rotary blades are inevitably addressed according to the shapes of both side surfaces of the ridge, and the traveling vehicle By rotating the rotary blade as the vehicle travels, the spiral scraping blade can scrape the soil on both sides of the ridge at an appropriate depth and scrape it out of the ridge together with the weeds. Therefore, unlike the conventional one, the rotary blade is optimally addressed to both sides of the ridge without paying attention to the insertion depth of the blade with respect to the surface of the ridge, and the side surface of the ridge is spirally scraped. This makes it possible to scrape the entire area at an appropriate depth to weed out reliably and efficiently near the root of the crop. Further, since the rotary blades described above are maintained while being applied to the side surface of the ridge, there is no need to worry about cutting the root of the crop planted on the top of the ridge by the scraping blade.

以下、本考案の一実施を図面に基づいて説明する。 図１及び図２にて示す除草機はゴルフ場の草刈車やトラクター等を利用した自走 車ａの前部に取付支持してあり、４個の回転刃１を備えている。 上記した各回転刃１は図３及び図４にて示すように円錐台形に形成し、その外周 に沿って螺旋状の掻刃３を突設してある。掻刃３は回転刃外周に沿って螺旋状に 巻回する鋼線３ａと、この鋼線３ａに沿って多数取り付ける爪３ｂとから構成し てある。 そして上記した回転刃１はその大径側の基端部から一体的に突出する回転軸１ａ を自走車ａの前部にて水平に支持される支持フレーム２により回転自在に軸支す ることにより小径側の端部を前方へ向けた状態で略水平に支持してある。また、 上記した４個の回転刃１は図１にて示すように支持フレーム２に対して間隔をお いて配置し、右側２個、左側２個の回転刃１を各々一対に成し、それら２個ずつ の回転刃１が平面視ハ形になるような傾斜角度を設けて取り付けてある。また、 一対になる回転刃１同士は図３にて示すように畦ｂの幅に合わせて配置され、両 回転刃１によって一本の畦ｂを挟むように構成してある。 尚、上記した回転刃１の外周に突設する掻刃３は図５及び図６にて示す回転刃１ ３のように所要高さを有する螺旋条板１３ａの縁に沿って凸部１３ｂを形成した ものであってもよい。しかし、上記した掻刃３は掻いた土や雑草を大径側端部へ 向けて送り出す為に適度な高さを有し、且つ線状に連続していることが肝要であ る。 An embodiment of the present invention will be described below with reference to the drawings. The weeding machine shown in FIGS. 1 and 2 is mounted and supported on the front part of a self-propelled vehicle a that uses a mowing car or a tractor on a golf course, and is provided with four rotary blades 1. Each of the rotary blades 1 described above is formed in a truncated cone shape as shown in FIGS. 3 and 4, and spiral scraping blades 3 are provided so as to protrude along the outer periphery thereof. The scraping blade 3 is composed of a steel wire 3a spirally wound around the outer circumference of the rotary blade, and a plurality of claws 3b attached along the steel wire 3a. The rotary blade 1 described above rotatably supports a rotary shaft 1a, which integrally projects from the base end portion on the large diameter side, by a support frame 2 which is horizontally supported at the front of the self-propelled vehicle a. Thus, the end portion on the small diameter side is supported substantially horizontally with the end portion facing forward. As shown in FIG. 1, the above-mentioned four rotary blades 1 are arranged at intervals with respect to the support frame 2, and two rotary blades 1 on the right side and two rotary blades 1 on the left side are formed as a pair. Two rotary blades 1 each are attached with an inclination angle so as to form a C shape in plan view. Further, as shown in FIG. 3, the pair of rotary blades 1 are arranged according to the width of the ridge b, and both rotary blades 1 sandwich one ridge b. Incidentally, the scraping blade 3 protrudingly provided on the outer periphery of the rotary blade 1 has a convex portion 13b along the edge of the spiral strip 13a having a required height like the rotary blade 13 shown in FIGS. It may be formed. However, it is important that the above-mentioned scraping blade 3 has an appropriate height and is linearly continuous in order to send scraped soil and weeds toward the large diameter side end.
【０００９】 一方、各回転刃１を支持する支持フレーム２は自走車ａの幅方向に延びるボッ クス状のフレームであり、その中央部に設けたアームを自走車ａの支持機構に対 して取り付けることにより回転刃１を支持したまま上下に油圧駆動できるように 支持してある。 そして、上記したフレーム２の内部は自走車ａから受けた駆動力を伝達する駆動 歯車４ａと駆動チェーン４ｂとが設けられ、これらの駆動機構４により伝達され る駆動力により各回転刃１が回動するようになつている。On the other hand, the support frame 2 that supports each rotary blade 1 is a box-shaped frame that extends in the width direction of the self-propelled vehicle a, and an arm provided at the center thereof opposes the support mechanism of the self-propelled vehicle a. It is supported so that the rotary blade 1 can be hydraulically driven up and down while being supported. A drive gear 4a and a drive chain 4b for transmitting the driving force received from the self-propelled vehicle a are provided inside the frame 2 described above, and each rotary blade 1 is driven by the driving force transmitted by these driving mechanisms 4. It is designed to rotate.
【００１０】 また、支持フレーム２の両端部からはＬ字形の腕板５が前方へ向けて突出する ように取り付けてあり、この腕板５の下端には各々保持車６が設けてある。 保持車６は支持フレーム６の高さを常に地面から一定に保持するためものであり 、図７及び図８にて示すように腕板５に沿って形成したガイド溝５ａに沿って支 軸６ａを移動可能に軸支することにより、その高さを段階的に調節できるように 構成してある。 尚、回転刃１の駆動機構は図９及び図１０にて示すもののように、自走車ａから 供給される油圧により駆動する油圧モータ８によって直接回動するように構成す ることもできる。Further, an L-shaped arm plate 5 is attached to both ends of the support frame 2 so as to project forward, and a holding wheel 6 is provided at the lower end of each arm plate 5. The holding wheel 6 is for keeping the height of the support frame 6 always constant from the ground, and as shown in FIGS. 7 and 8, the support shaft 6a is formed along a guide groove 5a formed along the arm plate 5. By movably supporting the shaft, its height can be adjusted in stages. The drive mechanism of the rotary blade 1 may be configured to be directly rotated by the hydraulic motor 8 driven by the hydraulic pressure supplied from the self-propelled vehicle a as shown in FIGS. 9 and 10.
【００１１】 上記したように構成した除草機を使用して畦ｂの側面に生える雑草を刈る際に は、走行車ａを畦ｂと平行に誘導すると共に、フレーム２の昇降操作により各回 転刃１を畦ｂの両側部に沿わせるように位置合わせする。 これにより回転刃１は図３、図４にて示すように畦ｂを両側から挟むように配置 される。この時、両回転刃１は円錐台形の外形と平面視ハ形の傾斜角を設けてい るためにその側面が各々畦ｂの両側面の傾斜に沿って必然的に宛てがわれること になる。 そして、自走車ａの走行に伴って各回転刃１を回転されると、該回転刃１の周面 に突設した螺旋状の掻刃３が回転し、畦ｂの両側面に生える雑草を地表から比較 的浅く掻き取り、掻き取った雑草と土とを螺旋状の掻刃３の回転により移動させ 、回転刃１の大形側端部から畦ｂの外側へ向けて掻き出しながら除草が行なわれ る。When mowing the weeds growing on the side surface of the ridge b using the weeding machine configured as described above, the traveling vehicle a is guided in parallel with the ridge b, and the frame 2 is moved up and down to rotate each blade. Align 1 along both sides of ridge b. As a result, the rotary blade 1 is arranged so as to sandwich the ridge b from both sides as shown in FIGS. At this time, since both rotary blades 1 are provided with an outer shape of a truncated cone and an angle of inclination of a C shape in a plan view, their side surfaces are necessarily inscribed along the inclination of both side surfaces of the ridge b. When each rotary blade 1 is rotated as the self-propelled vehicle a travels, the spiral scraping blade 3 protruding from the peripheral surface of the rotary blade 1 rotates and the weeds growing on both sides of the ridge b are rotated. Is relatively shallowly scraped from the ground surface, and the weeds and soil scraped are moved by the rotation of the spiral scraping blade 3, and weeding is performed while scraping from the large-sized end of the rotary blade 1 toward the outside of the ridge b. Is done.
【００１２】 而して、上記した除草機によれば、回転刃１が常に最適な状態で畦ｂの側面に 宛てがわれ、そして螺旋状の掻刃により畦ｂ側面を適度な深さで全面的に掻き取 って作物の根本付近まで全面的に除草することが可能である。 また、上記した回転刃１は図４にて示すように畦ｂの側面に宛てがわれた状態で 維持されるので、走行車ａを畦ｂに沿って走行させていれば掻刃３で畦ｂの頂上 部に植られる作物の根本を切断するようなこともない。[0012] Accordingly, according to the above weeding machine, the rotary blade 1 is always directed to the side surface of the ridge b in an optimal state, and the spiral scraping blade entirely covers the side surface of the ridge b at an appropriate depth. It is possible to completely weed up to near the root of the crop by scraping. Further, since the rotary blade 1 described above is maintained in a state of being directed to the side surface of the ridge b as shown in FIG. 4, if the traveling vehicle a is traveling along the ridge b, the rake blade 3 is used. It also does not cut off the roots of the crops planted at the top of b.
