Description

本発明は、ゴルフ場、公園などの芝生に目砂、肥料等を散布する散布機に関するもので、特に、水平に回転するローター上に目砂、肥料等を落下させて、このローターの回転によって目砂、肥料等を円弧状に均一に散布することができる目砂、肥料等の散布機に関する。   The present invention relates to a spreader that spreads sand, fertilizer, etc. on lawns such as golf courses and parks, and in particular, drops sand, fertilizer, etc. on a horizontally rotating rotor, and the rotation of this rotor It is related with spreaders, such as eye sand and manure, which can spread eye sand, fertilizer, etc. uniformly in an arc.

ゴルフ場、公園などでは、芝生の育成のために、芝目間に目土や肥料等を散布することが行われる。その作業には、台車で走行しながら、ホッパー内に収容された目土、肥料等をローターから散布する散布機が用いられることが一般的である。   In golf courses, parks, etc., soil and fertilizer are sprayed between the grasses to cultivate the lawn. For this work, it is common to use a spreader that spreads the soil, fertilizer and the like housed in the hopper from the rotor while traveling on the carriage.

従来のこの種の散布機を図１、図２を使用して説明する。
図１は、従来の目砂、肥料等の散布機の全体平面図であり、後方に設けられたローターが２枚の場合が示されている。図２は、図１の散布機の全体側面図である。 A conventional spreader of this type will be described with reference to FIGS.
FIG. 1 is an overall plan view of a conventional spreader such as mesh sand and fertilizer, and shows a case where there are two rotors provided on the rear side. FIG. 2 is an overall side view of the spreader of FIG.

図において、１はエンジン２により自走する走行台車で、前輪１ａと後輪１ｂを有し、油圧モーター３によって駆動される。４は目砂、肥料等の散布材料を入れるホッパーで、走行台車１の後輪１ｂの上方に設けられる。このホッパー４の下方は開放しており、開放部の下にコンベヤー５が配設される。このコンベヤー５は、ホッパー４の前後方に位置するコンベヤーローラー５ａ、５ｂによりベルト５ｃが後向きに駆動される。６はホッパー４の後面下部に設けられたシャッターで、散布材料の送り出し量を調整する。７は前記シャッター６の調整ハンドルで、リンク機溝８を介して送り出し量が調整される。９はコンベヤー５から送り出された散布材料を回転飛散させるローターで、台車１の後方に位置し、且つコンベヤー５の出口側下方に位置しており、油圧モーター１０により駆動され水平回転する。   In the figure, reference numeral 1 denotes a traveling cart that is self-propelled by an engine 2, which has a front wheel 1 a and a rear wheel 1 b and is driven by a hydraulic motor 3. Reference numeral 4 denotes a hopper for putting spray materials such as mesh sand and fertilizer, and is provided above the rear wheel 1 b of the traveling carriage 1. The lower part of this hopper 4 is open, and the conveyor 5 is arrange | positioned under the open part. In the conveyor 5, the belt 5 c is driven rearward by conveyor rollers 5 a and 5 b positioned in front of and behind the hopper 4. 6 is a shutter provided in the lower part of the rear surface of the hopper 4 and adjusts the amount of sprayed material to be delivered. Reference numeral 7 denotes an adjustment handle for the shutter 6, and the feed amount is adjusted via the link machine groove 8. Reference numeral 9 denotes a rotor for rotating and scattering the sprayed material delivered from the conveyor 5. The rotor 9 is located behind the carriage 1 and below the exit side of the conveyor 5, and is driven by the hydraulic motor 10 to rotate horizontally.

ローター９は円盤９ａと、その上面に回転中心から半径方向放射状に複数個設けられたフィン９ｂで構成される。図では、ローター９が２枚設けられた場合が示され、２枚のローター９が互いに逆方向に回転して台車１の進行方向に向かって、中央から外側に目砂を飛散するようになっている。１１はシュートで、コンベヤー５の後方下端に位置し、且つ前記ローター９の上方の進行方向側に位置している。図では、ローター９が２枚の場合が示されているので、前記シュート１１はコンベヤー５から送り出された散布材料を二分してローター９の上面へ落下させるようになっている。   The rotor 9 includes a disk 9a and a plurality of fins 9b provided on the upper surface thereof in a radial direction from the center of rotation. In the figure, a case where two rotors 9 are provided is shown, and the two rotors 9 rotate in opposite directions and scatter dust from the center toward the outside in the traveling direction of the carriage 1. ing. Reference numeral 11 denotes a chute, which is located at the lower rear end of the conveyor 5 and on the traveling direction side above the rotor 9. In the figure, the case where there are two rotors 9 is shown, so that the chute 11 bisects the sprayed material delivered from the conveyor 5 and drops it onto the upper surface of the rotor 9.

上述の従来の散布機を使用して散布材料を散布する場合、コンベヤー５から送り出された散布材料はシュート１１を介してローター５の上面に落下し、このローター５の水平回転によって円弧状に飛散される。この種のローターからの飛散は、ローターの回転遠心力によって行われるので、図３に示すように、円弧状軌跡を描いてその外周部（イ）に集中し、この飛散軌跡の外周部（イ）の更なる外側（ロ）及び内側（ハ）の飛散量は少なくなる。従って、図１のように２つのローターを持つ散布機の場合、図３に示すように、進行方向に向かって中央部の散布量が少なくなり、外側が多くなる。ローターが１つの散布機の場合も上記と同様の傾向を有し、散布幅の片側で散布量が多く、他方の側で少なくなる。   When spraying the sprayed material using the above-described conventional sprayer, the sprayed material delivered from the conveyor 5 falls onto the upper surface of the rotor 5 via the chute 11 and is scattered in an arc shape by the horizontal rotation of the rotor 5. Is done. Since scattering from this type of rotor is carried out by the rotational centrifugal force of the rotor, as shown in FIG. 3, an arc-shaped locus is drawn and concentrated on the outer peripheral portion (A), and the outer peripheral portion (I) ) Is further scattered outside (b) and inside (c). Therefore, in the case of a spreader having two rotors as shown in FIG. 1, as shown in FIG. 3, the amount of spread in the central portion decreases in the traveling direction, and the outside increases. In the case where the rotor is one spreader, the same tendency as described above is observed, and the spread amount is large on one side of the spread width and decreases on the other side.

このように従来の散布機では、目砂、肥料等の散布材料を均一に散布することができない問題があった。   Thus, in the conventional spreader, there was a problem that it was not possible to uniformly spread spray materials such as mesh sand and fertilizer.

本発明は、かかる従来技術の問題点を解消するために創案されたものであり、その目的は、散布幅方向に対して散布量の少なくなる領域の目砂、肥料等の散布量を増大させて、より均一な散布ができる構成を持つ目砂、肥料等の散布機を提供することにある。   The present invention was devised in order to solve the problems of the prior art, and its purpose is to increase the application amount of the sand, fertilizer, etc. in the area where the application amount decreases in the application width direction. Therefore, it is to provide a spreader for fine sand, fertilizer and the like having a configuration capable of more uniform spraying.

本発明者は、上記目的を達成するために鋭意検討した結果、目砂、肥料等の散布材料を飛散させるローターの構造を工夫することにより、従来に比べて均一な散布を容易に達成できることを見出し、本発明の完成に至った。   As a result of intensive studies to achieve the above object, the present inventor has devised a structure of a rotor that disperses spray materials such as fillers and fertilizers, thereby making it possible to easily achieve uniform spraying compared to the conventional case. The headline, the present invention has been completed.

即ち、本発明は、以下の（１）〜（８）の構成を有するものである。
（１）走行可能な台車と、その台車の後方に設けられた目砂、肥料等の散布材料を収容するホッパーと、このホッパーの下部出口を通ってホッパーから供給される散布材料を後方に搬送するコンベヤーと、このコンベヤーの終端下方に位置して水平回転すると共に、前記コンベヤーの終端から落下する散布材料を受け止めて放射方向に芝生に散布するローターとを備えた散布機において、前記ローターの上面側に半径方向に複数の上部フィンが設けられ、それらの上部フィンの間に開口部が設けられ、上部フィンによるローターの上面側からの散布材料の飛散と、開口部を通るローターの下面側からの散布材料の飛散を達成したことを特徴とする散布機。 That is, the present invention has the following configurations (1) to (8).
(1) A dolly that can travel, a hopper that is provided behind the dolly for containing sprayed material such as sand and fertilizer, and the sprayed material that is supplied from the hopper through the lower outlet of the hopper is transported backward. An upper surface of the rotor, wherein the upper surface of the rotor is provided with a conveyor that rotates and horizontally rotates at a position below the end of the conveyor and receives the sprayed material falling from the end of the conveyor and sprays it on the grass in a radial direction. A plurality of upper fins are provided in the radial direction on the side, and an opening is provided between the upper fins. Scattering of the scattered material from the upper surface side of the rotor by the upper fins, and from the lower surface side of the rotor passing through the opening portion A spraying machine characterized by achieving the scattering of spraying material .

（２）前記ローターの下面側に下部フィンを設けたことを特徴とする（１）に記載の散布機。
（３）前記上部フィンと前記下部フィンが異なる半径方向に設けられていることを特徴とする（２）に記載の散布機。
（４）前記上部フィンと前記下部フィンが同じ半径方向に設けられていることを特徴とする（２）に記載の散布機。
（５）前記下部フィンの半径方向長さが上部フィンのそれより小さいことを特徴とする（２）〜（４）のいずれかに記載の散布機。
（６）前記下部フィンの下端部が回転方向を指向するように折曲げられていることを特徴とする（２）〜（５）のいずれかに記載の散布機。
（７）前記開口部が円盤の１５〜８５％の面積で設けられていることを特徴とする（２）〜（６）のいずれかに記載の散布機。
（８）前記開口部が前記上部フィンより小径で開口し、かつ上部フィンの直前に設けられていることを特徴とする（２）〜（６）のいずれかに記載の散布機。 (2) The spreader according to (1), wherein a lower fin is provided on a lower surface side of the rotor.
(3) The spreader according to (2), wherein the upper fin and the lower fin are provided in different radial directions.
(4) The spreader according to (2), wherein the upper fin and the lower fin are provided in the same radial direction.
(5) The spreader according to any one of (2) to (4), wherein a radial length of the lower fin is smaller than that of the upper fin.
(6) The spreader according to any one of (2) to (5), wherein a lower end portion of the lower fin is bent so as to be directed in a rotation direction.
(7) The spreader according to any one of (2) to (6), wherein the opening is provided in an area of 15 to 85% of a disk.
(8) The spreader according to any one of (2) to (6), wherein the opening has a smaller diameter than the upper fin and is provided immediately before the upper fin.

本発明の散布機は、ローターの上面側に複数のフィンを放射状に設け、それらのフィン間に開口部を設けているので、ローターの上面側からの飛散と下面側からの飛散による散布が可能である。下面側からの飛散は、飛散距離が小さく、散布始点位置高さが上面側より低くなって早く落下するので、散布可能な領域が狭い。従って、下面側からの飛散によって、上面側のフィンによって散布された領域（到達距離が長い軌跡）（図１０のイ）より内側の領域（図１０のニ）にも飛散することになり、即ち、進行方向両側域より内側となる中央部に飛散するので、散布幅に対してより均一な散布を達成することができる。   The spreader of the present invention is provided with a plurality of fins radially on the upper surface side of the rotor, and an opening is provided between the fins, so that dispersion by scattering from the upper surface side of the rotor and from the lower surface side is possible. It is. Scattering from the lower surface side has a small scattering distance, and the spraying start point position height is lower than that of the upper surface side and falls early, so that the region that can be sprayed is narrow. Therefore, scattering from the lower surface side will also cause the region scattered by the fins on the upper surface side (the trajectory having a long reach) (a in FIG. 10) to the inner region (d in FIG. 10). Since it scatters in the central part that is inside from both sides in the traveling direction, it is possible to achieve more uniform spreading with respect to the spreading width.

また、本発明の散布機は、下面側にフィンを設け、下面側のフィンの半径方向長さを上面側のフィンより小さくすることにより、散布飛散の軌跡円弧の半径が小さくなるので、図１０に示すように、上述の中央部の散布領域においてより一層多く散布されることができる。   Further, the spreader of the present invention is provided with fins on the lower surface side, and by making the radial length of the fins on the lower surface side smaller than the fins on the upper surface side, the radius of the locus arc of scatter scattering becomes smaller. As shown in FIG. 5, it is possible to spread more in the above-mentioned central spray area.

本発明の散布機の実施形態を図面に基づいて説明するが、本発明はこれらに限定されるものではない。   Embodiments of the spreader of the present invention will be described with reference to the drawings, but the present invention is not limited thereto.

図４は、本発明の散布機の一実施形態の全体平面図であり、図５は、図４の本発明の散布機の全体側面図である。図４，５は、従来の散布機を示す図１，２とはローターの部分だけが異なる。従って、図において、前述した従来の散布機（図１，図２）と同一又は相当部分は同一符号を付けて説明を省略する。以下においては、本発明の独自の特徴部分であるローターに絞って説明する。   4 is an overall plan view of an embodiment of the spreader of the present invention, and FIG. 5 is an overall side view of the spreader of the present invention of FIG. 4 and 5 differ from FIGS. 1 and 2 showing a conventional spreader only in the rotor portion. Accordingly, in the figure, the same or corresponding parts as those of the above-described conventional spreader (FIGS. 1 and 2) are denoted by the same reference numerals and description thereof is omitted. The following description will focus on the rotor, which is a unique feature of the present invention.

図６は、本発明の散布機の一実施形態を示すローターの平面図であり、図７は、図６のローターの側面図である。図において、ローター９の円盤９ａには、その上面側に半径方向に放射状に複数個（図では４つ）、好ましくは３〜８個の上部フィン９ｂが設けられ、それらの上部フィン９ｂ間に開口部９ｃが設けられている。この開口部９ｃは、扇形、三角形等の形状で作られ、この開口部９ｃからも散布材料が飛散される。円盤９ａ中の開口部９ｃの面積割合は、ローターの上下からの希望の散布量に依存するが、１５〜８５％であることが好ましい。円盤９ａの下面側には、下部フィン９ｄが半径方向に放射状に複数個（図では４つ）、好ましくは上部フィンと同数で配設される。下部フィン９ｄは、飛散方向を安定させるためにその下端部９ｅが回転方向を指向するように折曲げて形成されることが好ましい。   FIG. 6 is a plan view of a rotor showing an embodiment of the spreader of the present invention, and FIG. 7 is a side view of the rotor of FIG. In the drawing, the disk 9a of the rotor 9 is provided with a plurality (four in the figure), preferably 3 to 8 upper fins 9b in the radial direction on the upper surface side, and between these upper fins 9b. An opening 9c is provided. The opening 9c is formed in a fan shape, a triangle, or the like, and the spray material is scattered from the opening 9c. The area ratio of the opening 9c in the disk 9a depends on a desired amount of application from above and below the rotor, but is preferably 15 to 85%. On the lower surface side of the disk 9a, a plurality of lower fins 9d are radially arranged in the radial direction (four in the figure), preferably the same number as the upper fins. The lower fin 9d is preferably formed by bending so that the lower end portion 9e is directed in the rotational direction in order to stabilize the scattering direction.

図８は、本発明の散布機の他の実施形態を示すローターの平面図であり、図９は、図８のローターの側面図である。図８，９は、下部フィンの長さ以外は図６，７の実施形態と同じである。図において、下部フィン９ｄ′は、その半径方向長さが上部フィン９ｂのそれより小さくなるように円盤９ａの下側に取付けられている。これにより、下部フィン９ｄ′より飛散する散布材料は、散布飛散の軌跡円弧が小さくなって飛散するようになっている。   FIG. 8 is a plan view of a rotor showing another embodiment of the spreader of the present invention, and FIG. 9 is a side view of the rotor of FIG. 8 and 9 are the same as the embodiment of FIGS. 6 and 7 except for the length of the lower fin. In the drawing, the lower fin 9d 'is attached to the lower side of the disk 9a so that its radial length is smaller than that of the upper fin 9b. As a result, the scattering material scattered from the lower fin 9d ′ is scattered with the locus arc of the scattering scattering being reduced.

図１１は、本発明の散布機の他の実施形態を示すローターの斜視図である。図において、ローター９は、上部円盤９ａと下部円盤９ｆとそれらを貫通する開口部９ｃとから構成されており、これらの円盤の間に下部フィン９ｄが挟み込まれる形で設けられている。この実施形態は、ローターの構造を強化したい場合に好適である。   FIG. 11 is a perspective view of a rotor showing another embodiment of the spreader of the present invention. In the figure, the rotor 9 is composed of an upper disk 9a, a lower disk 9f, and an opening 9c passing therethrough, and a lower fin 9d is sandwiched between these disks. This embodiment is suitable when it is desired to strengthen the rotor structure.

図１２は、本発明の散布機の他の実施形態を示すローターの平面図であり、図１３は、図１２の側面図であり、図１４は、図１２のＡ−Ａ方向の断面図である。図において、上部フィン９ｂと下部フィン９ｄ，９ｄ′は、円盤９ａを挟んで同位置に対称的に設けられ、開口部９ｃは上下のフィン９ｂ，９ｄ，９ｄ′の直前から開口されている。９ｇは下部フィン９ｄ，９ｄ′への案内板である。開口部９ｃは上部フィン９ｂより小径で開口し、フィン直前に設けられているので、円盤９ａ上に落下した散布材料の一部は上部フィン９ｂに跳ね返り、開口部９ｃ、案内板９ｇによって下部フィン９ｄ，９ｄ′へと容易に導かれる。これにより、円弧状の散布飛散軌跡が二分された上下二段の軌跡となり、均一な散布のより一層の効果が増す。   12 is a plan view of a rotor showing another embodiment of the spreader of the present invention, FIG. 13 is a side view of FIG. 12, and FIG. 14 is a cross-sectional view in the AA direction of FIG. is there. In the figure, an upper fin 9b and lower fins 9d and 9d 'are provided symmetrically at the same position with a disk 9a in between, and an opening 9c is opened immediately before the upper and lower fins 9b, 9d and 9d'. 9g is a guide plate to the lower fins 9d, 9d '. Since the opening 9c has a smaller diameter than the upper fin 9b and is provided immediately before the fin, a part of the sprayed material dropped on the disk 9a bounces back to the upper fin 9b, and the lower fin is formed by the opening 9c and the guide plate 9g. 9d and 9d 'are easily guided. As a result, the arc-shaped scatter scattering trajectory is divided into two upper and lower trajectories, and the effect of uniform scatter is further increased.

本発明の散布機は、ローターの上下二段からの散布ができるので、上段からの散布だけでなく、下段からの散布によって上段の到達距離の長い領域の内側にも散布されることになり、結果として、散布幅方向に対して均一な量の散布を達成できる。また、下段に設けたフィンの半径方向長さを上段のフィンのそれより小さくすることにより、散布軌跡の半径が小さくなるので、更に散布幅方向に対して一層均一な散布を達成できる。従って、本発明の散布機は、ゴルフ場・公園など散布作業に極めて有用である。   Since the spreader of the present invention can spread from the upper and lower two stages of the rotor, it will be spread not only from the upper stage, but also from the lower stage to the inside of the long area of the upper reach, As a result, it is possible to achieve a uniform amount of spreading in the spreading width direction. Further, by making the radial length of the fins provided in the lower stage smaller than that of the upper fins, the radius of the application trajectory is reduced, so that more uniform application can be achieved in the application width direction. Therefore, the spreader of the present invention is extremely useful for spreading work such as golf courses and parks.
