Description

この発明は、海水浴場等の砂地に散在する様々なゴミを回収するビーリクリーナ用のゴミ回収ステーションに関する。   The present invention relates to a garbage collection station for a bee cleaner that collects various kinds of garbage scattered in sand such as a beach.

従来、上記ビーチクリーナは、牽引車両に牽引されて砂地を走行して散在するゴミを回収した後、砂地の所定位置に設置したゴミ回収ステーションに乗り上げることで、ゴミの回収を可能にしている(例えば、特許文献1参照。)。
上記ゴミ回収ステーションは、左右一対の接地部材のそれぞれに緩やかな山形の案内部材を設けると共に、各接地部材間を左右方向に延びる連結部材で一体に連結してなり、例えば各接地部材から下方に突出するフート部材を砂地に差し込んで所定位置に設置される。このゴミ回収ステーションの両案内部材にビーチクリーナの両側部が乗り上げることで、ビーチクリーナが砂地からリフトアップされて集めたゴミの回収が行われる。
特開2002−356827号公報
Conventionally, the beach cleaner has been towed by a towing vehicle, collects trash scattered by running on sand, and then rides on a trash collection station installed at a predetermined position on the sand to enable collection of trash ( For example, see Patent Document 1.)
The garbage collection station is provided with a gentle mountain-shaped guide member on each of the pair of left and right grounding members and integrally connected between the grounding members by a connecting member extending in the left-right direction. The protruding foot member is inserted into the sand and installed at a predetermined position. The both sides of the beach cleaner ride on both guide members of the waste collection station, and the beach cleaner is lifted up from the sand and collected.
Japanese Patent Laid-Open No. 2002-356827

ところで、上記ビーチクリーナ及びゴミ回収ステーションは、所定の作業場所までトレーラに積載された状態で運搬されることから、比較的大型のゴミ回収ステーションは分割可能な構成とすることが望ましい。
しかしながら、上記従来の構成においては、連結部材の左右中間部あるいは接地部材及び案内部材の前後中間部を分割可能な連結部とし、立体的に大型のゴミ回収ステーションを単に前後又は左右に分割する構造としていることから、各分割体がそれぞれ嵩張り易く、その持ち運びやトレーラに対する積み降ろしがし難く、かつ分割体同士の組み付けもし難いという課題があった。
そこでこの発明は、分割後に嵩張り難く、かつ設置作業を容易にできるビーチクリーナ用ゴミ回収ステーションを提供する。
By the way, since the beach cleaner and the garbage collection station are transported in a state where they are loaded on a trailer to a predetermined work place, it is desirable that the relatively large garbage collection station be configured to be split.
However, in the above-described conventional configuration, the right and left intermediate part of the connecting member or the front and rear intermediate part of the grounding member and the guide member is a severable connecting part, and the three-dimensional large garbage collection station is simply divided into the front and rear or left and right. Therefore, there is a problem that each of the divided bodies is easily bulky, is difficult to carry and load and unload from the trailer, and is difficult to assemble the divided bodies.
Therefore, the present invention provides a beach cleaner garbage collection station which is difficult to be bulky after being divided and can be easily installed.

上記課題の解決手段として、請求項1に記載した発明は、一対の接地部材(例えば実施例の接地部材43)のそれぞれに山形の案内部材(例えば実施例の案内部材44)を設けると共に、前記各接地部材間を連結部材(例えば実施例の連結部材42)で一体に連結してなり、牽引車両(例えば実施例の車両1)に牽引されて砂地を走行してゴミを回収するビーチクリーナ(例えば実施例の各ビーチクリーナ20,50)を乗り上げさせて、該ビーチクリーナが集めたゴミの回収を可能とするビーチクリーナ用ゴミ回収ステーション(例えば実施例のゴミ回収ステーション40)において、前記連結部材の端部と接地部材とを着脱可能に連結する連結部(例えば実施例の連結パイプ46)を備え、前記連結部は、前記連結部材の端部を挿入可能な筒状であり、該連結部に連結部材を挿入した状態で、これらを貫通する係止部材(例えば実施例の係止ピン47)が差し込まれると共に、該係止部材が砂地に差し込まれることを特徴とする。 As a means for solving the above problems, the invention described in claim 1 is provided with a mountain-shaped guide member (for example, the guide member 44 of the embodiment) on each of a pair of ground members (for example, the ground member 43 of the embodiment), and Each grounding member is integrally connected by a connecting member (for example, the connecting member 42 of the embodiment), and is a beach cleaner (which is pulled by a towing vehicle (for example, the vehicle 1 of the embodiment) and travels on sand and collects garbage. For example, in the beach cleaner garbage collection station (for example, the garbage collection station 40 of the embodiment) that allows the beach cleaners 20 and 50) of the embodiment to ride and collect the garbage collected by the beach cleaner, the connecting member a connecting portion for connecting the ends of the ground member removably (e.g. coupling of example pipe 46), the connecting portion is insertable end portion of the coupling member A tubular, while inserting the connecting member to the connecting portion, together with the locking member extending therethrough (e.g. engaging pins 47 in the embodiment) is inserted, that the locking member is inserted into the sand Features.

この発明によれば、接地部材及び案内部材を主とする構造体と連結部材とに分割可能とすることで、各分割体がそれぞれ平面的になり、分割後に嵩張り難く、各分割体の持ち運びやトレーラに対する積み降ろしがし易く、かつ分割体同士の組み付けもし易くなり、設置作業を容易にすることができる。 According to the present invention , by allowing the grounding member and the guide member to be divided into the main structure and the connecting member, each divided body becomes planar and difficult to be bulky after being divided. In addition, it is easy to load and unload to and from the trailer, and it is easy to assemble the divided bodies, thereby facilitating the installation work.

この発明によれば、係止部材が連結部材と連結部とを抜き差し不能に連結すると共に、ゴミ回収ステーションの砂地に対する移動を抑制することができる。


According to this invention , while a locking member connects a connection member and a connection part so that insertion / extraction is impossible, the movement with respect to the sandy ground of a garbage collection station can be suppressed.


以下、この発明の実施例について図面を参照して説明する。
図1に示す車両1は、小型軽量に構成された車体の前後に、比較的大径の低圧バルーンタイヤである左右の前輪2及び後輪3を備え、最低地上高を大きく確保して主に不整地での走破性を高めた所謂ATV(All Terrain Vehicle)として構成される。車両1の車体フレーム4は、車幅方向中央部において前後に長いボックス構造を形成し、該車体フレーム4の略中央部には、車両1の原動機としてのエンジン5が搭載される。
Embodiments of the present invention will be described below with reference to the drawings.
A vehicle 1 shown in FIG. 1 includes left and right front wheels 2 and rear wheels 3 that are relatively large-diameter low-pressure balloon tires in front of and behind a vehicle body that is small and light. It is configured as a so-called ATV (All Terrain Vehicle) with improved running performance on rough terrain. The vehicle body frame 4 of the vehicle 1 forms a box structure that is long in the front-rear direction in the center portion in the vehicle width direction.

The engine 5 is, for example, a water-cooled single cylinder engine, and outputs the rotational power of the crankshaft to the front and rear propeller shafts 6a and 6b via a gear meshing type transmission. The rotational power output to the front and rear propeller shafts 6a and 6b is output to the left and right front wheels 2 or the rear wheel 3 via the front and rear speed reduction devices 7a and 7b, respectively.
Here, the vehicle 1 is a so-called semi-automatic vehicle in which the gear ratio of the transmission can be electrically changed. For example, the gear ratio can be changed only by operating a change button or the like without performing clutch operation through a centrifugal clutch. Is possible. Such a vehicle 1 is suitable for traveling with a large traveling load and traveling at a constant speed as compared with a vehicle having a belt-type transmission.

左右前輪2は、車体フレーム4の前部に独立懸架式のフロントサスペンション8aを介して懸架され、左右後輪3は、車体フレーム4の後部に例えばスイングアーム式のリアサスペンション8bを介して懸架される。リアサスペンション8bのスイングアーム9の後端部には、トレーラ牽引用のトレーラヒッチ11が設けられる。なお、図中符号12aは車体フレーム4前部に支持されるフロントキャリアを、符号12bは車体フレーム4後部に支持されるリアキャリアをそれぞれ示す。   The left and right front wheels 2 are suspended from the front portion of the vehicle body frame 4 via an independent suspension type front suspension 8a, and the left and right rear wheels 3 are suspended from the rear portion of the vehicle body frame 4 via, for example, a swing arm type rear suspension 8b. The A trailer hitch 11 for towing a trailer is provided at the rear end of the swing arm 9 of the rear suspension 8b. In the figure, reference numeral 12a denotes a front carrier supported at the front part of the vehicle body frame 4, and reference numeral 12b denotes a rear carrier supported at the rear part of the vehicle body frame 4.

上記車両1は、後述する第一及び第二ビーチクリーナ20,50並びにゴミ回収ステーション40を運搬するトレーラ13を牽引可能である。
トレーラ13は、例えばその車体フレーム14の下部両側に左右一対の車輪15を有すると共に、前記車体フレーム14上には上方に開放する上下に浅い箱型のキャリア16を有し、かつ車体フレーム14の前部下側から前方に向けて牽引アーム17を延出してなる。牽引アーム17の前端部には、前記トレーラヒッチ11に対応するヒッチカプラ17aが設けられる。
The vehicle 1 can pull a trailer 13 that transports first and second beach cleaners 20 and 50 and a garbage collection station 40 described later.
The trailer 13 has, for example, a pair of left and right wheels 15 on both lower sides of the body frame 14, and has a shallow box-shaped carrier 16 that opens upward and downward on the body frame 14. A pulling arm 17 is extended from the lower front side toward the front. A hitch coupler 17 a corresponding to the trailer hitch 11 is provided at the front end portion of the pulling arm 17.

キャリア16前後の左右両側の上縁部には、ゴミ回収ステーション40における後述する各連結パイプ46を支持する受け具16aが設けられる。受け具16aは上方に開放するV字状の凹部を有し、該凹部内に上下を逆にした積載状態のゴミ回収ステーション40における前記連結パイプ46が落とし込まれて保持される。また、前記積載状態のゴミ回収ステーション40上には、例えば後述する接地部材43に係合し移動を規制された状態で第二ビーチクリーナ50が搭載されると共に、例えばキャリア16内に収容された状態で第一ビーチクリーナ20が搭載される。   At the upper edge portions on both the left and right sides before and after the carrier 16, a receiver 16 a that supports each connection pipe 46 described later in the dust collection station 40 is provided. The receptacle 16a has a V-shaped recess that opens upward, and the connecting pipe 46 in the garbage collection station 40 in a stacked state upside down is dropped and held in the recess. On the loaded garbage collection station 40, for example, a second beach cleaner 50 is mounted in a state in which movement is restricted by engaging with a grounding member 43 described later, and accommodated in the carrier 16, for example. The first beach cleaner 20 is mounted in the state.

なお、図1に示す各ビーチクリーナ20,50及びゴミ回収ステーション40はトレーラ13への積載状態を示し、図2以降に示す各ビーチクリーナ20,50及びゴミ回収ステーション40は特に記載がなければ砂地上での使用状態を示す。また、図中線GLは地面(砂地上面)を、図中線CLは車両1及びこれに牽引される各ビーチクリーナ20,50並びにこれらを通過させるゴミ回収ステーション40(以下、車両等という)の左右中心を示し、矢印FRは前記車両等の走行方向(前後方向)における前方を、矢印UPは前記車両等の上下方向における上方を、矢印LHは前記車両等の左右方向における左方をそれぞれ示す。   The beach cleaners 20 and 50 and the garbage collection station 40 shown in FIG. 1 indicate the state of loading on the trailer 13, and the beach cleaners 20 and 50 and the garbage collection station 40 shown in FIG. The usage state is shown above. In addition, the line GL in the figure is the ground (the upper surface of the sand), and the line CL in the figure is the vehicle 1 and the beach cleaners 20 and 50 pulled by the vehicle 1 and the garbage collection station 40 (hereinafter referred to as a vehicle or the like) that passes these. The left and right centers are indicated, the arrow FR indicates the front in the traveling direction (front-rear direction) of the vehicle, the arrow UP indicates the upper direction in the vertical direction of the vehicle, and the arrow LH indicates the left side in the horizontal direction of the vehicle. .

各ビーチクリーナ20,50は、車両1に牽引されて海岸等の砂地(砂浜)を走行しつつ、該砂地に散在する様々なゴミを回収する。各ビーチクリーナ20,50が集めたゴミは、砂地の所定箇所に設置されたゴミ回収ステーション40においてまとめて回収される。各ビーチクリーナ20,50及びゴミ回収ステーション40は、例えばステンレス等の複数種の鋼材を溶接等の結合手段を用いて適宜組み立ててなる。なお、各ビーチクリーナ20,50をトラクターで牽引するようにしてもよい。   Each of the beach cleaners 20 and 50 is pulled by the vehicle 1 and travels on a sandy area (sandy beach) such as a coast, and collects various kinds of garbage scattered on the sandy area. The garbage collected by the beach cleaners 20 and 50 is collected together at a garbage collection station 40 installed at a predetermined location on the sand. Each of the beach cleaners 20 and 50 and the dust collection station 40 are appropriately assembled by using a plurality of types of steel materials such as stainless steel using a joining means such as welding. Each beach cleaner 20, 50 may be pulled by a tractor.

図2,3に示すように、第一ビーチクリーナ20は、前記走行方向に沿って延びる複数(例えば十五本)の縦部材21を互いに幅方向(左右方向)にほぼ等間隔に並べてスノコ状のフレーム22を形成し、かつ各縦部材21に下方に突出する複数のサンドピン23を着脱可能に取り付けてなる。なお、第一ビーチクリーナ20は左右対称の構成を有している。   As shown in FIGS. 2 and 3, the first beach cleaner 20 has a plurality of (for example, fifteen) vertical members 21 extending along the traveling direction and arranged in a width direction (left and right direction) at substantially equal intervals. A plurality of sand pins 23 that form a frame 22 and project downward from each vertical member 21 are detachably attached. The first beach cleaner 20 has a symmetrical configuration.

縦部材21は、例えば円形鋼管(角形鋼管でもよい)を前後方向に沿って配置し、その前後端部を斜め上前方又は後方に屈曲させてなる。この縦部材21が側面視で重なるように左右に複数並置され、その前端を左右方向に沿って延びる例えば角形鋼管からなる前横部材24aに斜め下後方から突き当てて結合されると共に、後端を左右方向に沿って延びる例えば角形鋼管からなる後横部材24bに斜め下前方から突き当てて結合される。
これら各縦部材21及び横部材24a,24bからなる前記フレーム22は、上面視で横長の長方形状に形成される。なお、フレーム22の左右幅は車両1の左右幅に対して同等かやや大きく、かつ後述するゴミ回収ステーション40の左右側部構造体41間の左右幅よりも狭くなるように設定される。
The vertical member 21 is formed, for example, by arranging a circular steel pipe (or a square steel pipe) along the front-rear direction, and bending the front-rear end part obliquely upward forward or rearward. A plurality of the vertical members 21 are juxtaposed side by side so as to overlap in a side view, and the front end of the vertical member 21 is joined to a front horizontal member 24a made of, for example, a square steel pipe extending in the left-right direction obliquely from below and rear, and the rear end Are connected to the rear lateral member 24b made of, for example, a square steel pipe extending in the left-right direction, obliquely from the lower front side.
The frame 22 including the vertical members 21 and the horizontal members 24a and 24b is formed in a horizontally long rectangular shape when viewed from above. The left and right width of the frame 22 is set to be equal to or slightly larger than the left and right width of the vehicle 1 and narrower than the left and right width between the left and right side structures 41 of the dust collection station 40 described later.

各縦部材21の前部、前後中間部、及び後部には、それぞれ前記サンドピン23を取り付け可能とされる。すなわち、複数のサンドピン23を前後三列に配置可能とされる。これにより、低速走行時における走行抵抗が抑えられ、かつ砂地の固さ等に応じてサンドピン23の本数を減らすことでさらに走行抵抗を抑えることが可能である。各サンドピン23のフレーム22下面からの突出長さは、砂地中の生態系への影響を抑えるべく最大100mmとされる。
このような第一ビーチクリーナ20が砂地を走行することで、散在する比較的大型のゴミ(ロープ、網、流木等)が、各サンドピン23に引っ掛かるあるいは絡まるようにして掻き集められる。
The sand pin 23 can be attached to the front part, front-rear intermediate part, and rear part of each vertical member 21. That is, a plurality of sand pins 23 can be arranged in three rows in the front and rear direction. As a result, running resistance during low-speed running can be suppressed, and the running resistance can be further reduced by reducing the number of sand pins 23 according to the hardness of the sand. The protruding length of each sand pin 23 from the lower surface of the frame 22 is set to a maximum of 100 mm in order to suppress the influence on the ecosystem in the sand.
As the first beach cleaner 20 travels through the sand, scattered and relatively large garbage (rope, net, driftwood, etc.) is scraped and collected by being caught or entangled with each sand pin 23.

図4を併せて参照し、サンドピン23は、縦部材21の下部外面に整合するように湾曲した板状部材25と、該板状部材25を上下に貫通するピン本体26と、該ピン本体26の下部と板状部材25の後部との間に跨る筋交い状のサポート部材27とを有してなり、下側ほど細い側面視三角形状に形成される。ピン本体26の上部は雄ネジ部26aとされ、この雄ネジ部26aが縦部材21を下方から貫通しその上方に突出した状態で、板状部材25が縦部材21の下面に当接し、この状態で雄ネジ部26aに袋ナット28を螺着し締め込むことで、サンドピン23が縦部材21に固定される。なお、縦部材21におけるピン本体26が貫通する部位には円筒状のカラー29が挿通固定されている。   Referring also to FIG. 4, the sand pin 23 includes a plate-like member 25 that is curved so as to be aligned with the lower outer surface of the vertical member 21, a pin main body 26 that vertically penetrates the plate-like member 25, and the pin main body 26. A brace-like support member 27 straddling the lower part of the plate-like member 25 and the rear part of the plate-like member 25 is formed in a triangular shape in a side view that is thinner toward the lower side. The upper portion of the pin body 26 is a male screw portion 26a. With the male screw portion 26a penetrating the vertical member 21 from below and protruding upward, the plate-like member 25 contacts the lower surface of the vertical member 21. In this state, the sand pin 23 is fixed to the vertical member 21 by screwing and tightening the cap nut 28 on the male screw portion 26a. A cylindrical collar 29 is inserted and fixed in a portion of the vertical member 21 through which the pin body 26 penetrates.

なお、図5に示すように、角形鋼管からなる縦部材21’に対しては、これに対応するサンドピン23’を用いればよい。すなわち、サンドピン23’は、縦部材21’の下部外面に整合するように断面コ字状をなす板状部材25’を有し、該板状部材25’が縦部材21’の下部に整合した状態で、雄ネジ部26aに袋ナット28を螺着し締め込むことで、サンドピン23’が縦部材21’に固定される。縦部材21’は、その断面形状における左右幅が比較的広く、このような縦部材21’を用いることで、第一ビーチクリーナ20の砂地に対する滑走性が向上する。また、ピン本体26の下端部を前方に屈曲させて折り返し部26bを形成すれば、ゴミ回収能力がさらに向上する。   In addition, as shown in FIG. 5, what is necessary is just to use the sand pin 23 'corresponding to this with respect to the vertical member 21' which consists of a square steel pipe. That is, the sand pin 23 ′ has a plate-like member 25 ′ having a U-shaped cross section so as to align with the lower outer surface of the vertical member 21 ′, and the plate-like member 25 ′ is aligned with the lower part of the vertical member 21 ′. In this state, the sand pin 23 ′ is fixed to the vertical member 21 ′ by screwing and tightening the cap nut 28 onto the male screw portion 26 a. The vertical member 21 ′ has a relatively wide left-right width in the cross-sectional shape, and by using such a vertical member 21 ′, the sliding performance of the first beach cleaner 20 with respect to the sand is improved. Further, if the folded portion 26b is formed by bending the lower end portion of the pin body 26 forward, the dust collecting ability is further improved.

ここで、図6,7に示すように、第一ビーチクリーナ20のフレーム22上には、サンドピン23の砂中への沈み込み量を調整するための錘載せ部31が設置可能である。
図8を併せて参照し、錘載せ部31は、左右に並ぶベース部32を支持ブラケット33を介して一体に結合してなる。各ベース部32は前後に長い縦長のもので、フレーム22における隣り合う縦部材21の左右間隔と同一の左右間隔を有して配置される。各ベース部32の前後端部には、フレーム22に取り付けられて前後に並ぶサンドピン23の雄ネジ部26aを挿通可能な挿通孔32aが形成される。これら各ベース部32の前後中間部間に跨るように、後方に開放する断面コ字状をなして左右に延びる支持ブラケット33が渡設される。
Here, as shown in FIGS. 6 and 7, on the frame 22 of the first beach cleaner 20, a weight mounting portion 31 for adjusting the amount of sinking of the sand pin 23 into the sand can be installed.
Referring also to FIG. 8, the weight mounting portion 31 is formed by integrally joining base portions 32 arranged on the left and right sides via a support bracket 33. Each base portion 32 is long and long in the front-rear direction, and is arranged with the same left-right distance as the left-right distance between adjacent vertical members 21 in the frame 22. At the front and rear end portions of each base portion 32, an insertion hole 32a is formed through which the male screw portion 26a of the sand pin 23 attached to the frame 22 and arranged front and rear can be inserted. A support bracket 33 extending in the left-right direction with a U-shaped cross-section opening rearward is provided so as to straddle between the front and rear intermediate portions of each base portion 32.

このような錘載せ部31は、フレーム22におけるサンドピン23を有する部位に対して、該サンドピン23との共締めにより取り付け可能であり、またサンドピン23を有さない部位に対しても、対応するボルト等により取り付け可能である。すなわち、フレーム22上の任意の部位に任意の数だけ錘載せ部31を設置可能である。   Such a weight mounting portion 31 can be attached to the portion having the sand pin 23 in the frame 22 by co-tightening with the sand pin 23, and the corresponding bolt is also attached to the portion having no sand pin 23. It can be attached by such as. That is, an arbitrary number of weight mounting portions 31 can be installed at an arbitrary site on the frame 22.

図9を併せて参照し、錘載せ部31に支持されるウェイト34は、支持ブラケット33に後方から嵌合する下ブロック34aと、該下ブロック34aに上方から嵌合する上ブロック34bとに分割構成される。
下ブロック34aは、その前端部が支持ブラケット33内に入り込んだ状態で、これらを上下に貫通する係止ピン35aを介して支持ブラケット33に連結固定される。上ブロック34bは、その下部を下ブロック34aの上部に整合させた状態で、これらを上下に貫通する連結ボルト35bを介して下ブロック34aに連結固定される。
Referring also to FIG. 9, the weight 34 supported by the weight mounting portion 31 is divided into a lower block 34 a fitted into the support bracket 33 from the rear and an upper block 34 b fitted into the lower block 34 a from above. Composed.
The lower block 34 a is connected and fixed to the support bracket 33 via a locking pin 35 a that vertically penetrates the lower block 34 a with its front end portion entering the support bracket 33. The upper block 34b is connected and fixed to the lower block 34a via a connecting bolt 35b that vertically penetrates the upper block 34b with its lower part aligned with the upper part of the lower block 34a.

ここで、図10,11に示すように、車両1のフロントキャリア12aには、第一ビーチクリーナ20にウェイト34を搭載する等により走行抵抗が増加した場合にも、前輪荷重を確保して良好な駆動力を得るべく所定の錘載せ部31’が設置可能である。
錘載せ部31’は、フロントキャリア12aの上面に沿うベース部32’上に前記錘載せ部31と同様の支持ブラケット33を一体に設けてなる。ベース部32’は上面視長方形状の板状をなし、その前後下面側がフロントキャリア12aを構成する左右方向に沿うパイプ部材に着脱可能に取り付けられる。
Here, as shown in FIGS. 10 and 11, the front carrier 12a of the vehicle 1 has a good front wheel load even when the running resistance is increased by mounting a weight 34 on the first beach cleaner 20 or the like. In order to obtain a sufficient driving force, a predetermined weight mounting portion 31 ′ can be installed.
The weight mounting portion 31 ′ is formed by integrally providing a support bracket 33 similar to the weight mounting portion 31 on a base portion 32 ′ along the upper surface of the front carrier 12a.

Referring also to FIG. 14, the traction rod 38 extends in a V shape or a Y shape as viewed from above from one end side connected to the trailer hitch 11 toward the left and right traction portion 37. The hitch coupler 17a corresponding to the trailer hitch 11 is provided.

フレーム22の左右外側には、その外側端から左右外方に向けて張り出すリフトアーム39が設けられる。リフトアーム39は、例えば上面視方形状をなす枠型のもので、その左右中間部は略水平とされ、かつ左右内側部が斜め下内側に、左右外側部が斜め下外側にそれぞれ屈曲形成される。これら左右リフトアーム39の外側端間の左右幅は、ゴミ回収ステーション40の左右側部構造体41間の左右幅に対して広く、車両1に牽引された第一ビーチクリーナ20が左右側部構造体41間に進入した際には、左右リフトアーム39が左右側部構造体41に乗り上げることで、第一ビーチクリーナ20が所定量リフトアップされる。なお、左右側部構造体41間の距離は車両1の左右幅よりも大きく、該車両1が左右側部構造体41間を通過可能である。   On the left and right outer sides of the frame 22, a lift arm 39 that protrudes from the outer end toward the left and right outwards is provided. The lift arm 39 is, for example, a frame shape having a top view shape. The left and right intermediate portions are substantially horizontal, the left and right inner portions are bent obliquely inside, and the left and right outside portions are bent obliquely below and outside. The The left and right widths between the outer ends of the left and right lift arms 39 are wider than the left and right widths between the left and right side structure 41 of the garbage collection station 40, and the first beach cleaner 20 pulled by the vehicle 1 has the left and right side structures. When entering between the bodies 41, the left and right lift arms 39 ride on the left and right side structure 41, whereby the first beach cleaner 20 is lifted up by a predetermined amount. The distance between the left and right side structure 41 is larger than the left and right width of the vehicle 1, and the vehicle 1 can pass between the left and right side structure 41.

図13,14に示すように、ゴミ回収ステーション40において、前述の如く第一ビーチクリーナ20がリフトアップされた際には、各サンドピン23が砂地上面から十分に離間すると共に、該各サンドピン23が掻き集めたゴミを砂地上に落下させることができ、もって該ゴミをまとめて回収可能となる。   As shown in FIGS. 13 and 14, when the first beach cleaner 20 is lifted up in the garbage collection station 40 as described above, each sand pin 23 is sufficiently separated from the upper surface of the sand, and each sand pin 23 is The scraped garbage can be dropped onto the sand, so that the garbage can be collected together.

ゴミ回収ステーション40は、左右側部構造体41同士を前後一対の連結部材42により一体的に連結してなるもので、例えば前後対象かつ左右対称の構成を有している。
左右側部構造体41は、前後方向に沿う例えば円形鋼管からなるバー状の接地部材43上に、側面視で略前後対称の緩やかな山形をなす例えば円形鋼管からなる案内部材44を設け、これら各部材43,44の前後端部を互いに一体に結合してなる。
The garbage collection station 40 is formed by integrally connecting the left and right side structures 41 with a pair of front and rear connection members 42, and has, for example, a front-rear object and a symmetrical configuration.
The left-right part structure 41 is provided with, for example, a guide member 44 made of, for example, a circular steel pipe having a gentle mountain shape that is substantially symmetrical in the front-rear direction in a side view on a bar-shaped grounding member 43 made of, for example, a circular steel pipe along the front-rear direction. The front and rear end portions of the members 43 and 44 are integrally connected to each other.

左右接地部材43の前後端部には、上面視で前側又は後側ほど左右外側に位置するように傾斜するフート部材45が着脱可能に取り付けられる。各フート部材45は、各接地部材43と共に砂地上に接地するもので、これにより、ゴミ回収ステーション40がその接地面積を広げた状態で安定して設置される。   A foot member 45 is attached to the front and rear ends of the left and right grounding members 43 so as to be attachable and detachable so as to be positioned on the left and right outer sides as viewed from above. Each foot member 45 is grounded on the sand surface together with each grounding member 43, whereby the dust collection station 40 is stably installed with its grounding area expanded.

図15を併せて参照し、連結部材42は、例えば左右方向に沿う円形鋼管からなるもので、その端部が接地部材43の前部又は後部の下側に設けられた連結パイプ46に着脱可能に差し込まれた状態で、左右側部構造体41を一体的に連結する。すなわち、ゴミ回収ステーション40は比較的大型であることから、複数の分割体(左右側部構造体41及び前後連結部材42)に分割可能とされる。   Referring also to FIG. 15, the connecting member 42 is made of, for example, a circular steel pipe extending in the left-right direction, and its end can be attached to and detached from the connecting pipe 46 provided below the front part or the rear part of the grounding member 43. The right and left side structure 41 is integrally connected in a state of being inserted into the right and left sides. That is, since the garbage collection station 40 is relatively large, it can be divided into a plurality of divided bodies (left and right side structure 41 and front and rear connecting members 42).

接地部材43前後の連結パイプ46は、左右方向に沿う比較的短い円形鋼管からなり、その上部外周を接地部材43下側の切り欠きに整合させるようにしてこれに一体に結合される。すなわち、連結パイプ46は接地部材43下面から下方に突出しており、ゴミ回収ステーション40を砂地上に設置した際には砂中に食い込むことでゴミ回収ステーション40の移動を抑制する。   The connecting pipes 46 before and after the ground member 43 are made of a relatively short circular steel pipe along the left-right direction, and are integrally coupled to the upper outer periphery thereof so as to align with the notch below the ground member 43. That is, the connecting pipe 46 protrudes downward from the lower surface of the grounding member 43, and when the garbage collection station 40 is installed on the sand surface, the movement of the garbage collection station 40 is suppressed by biting into the sand.

連結パイプ46内に連結部材42の端部を所定量挿入した組み付け状態(例えば連結パイプ46及び連結部材42の外側端を一致させた状態)において、連結パイプ46及び連結部材42のそれぞれに形成された上下貫通孔42a,46aが例えば接地部材43の左右外方で重なり、これら各上下貫通孔42a,46aに所定の係止ピン47を差し込むことで、連結部材42及び接地部材43が前記組み付け状態で抜き差し不能に連結される。   In an assembled state in which a predetermined amount of the end of the connecting member 42 is inserted into the connecting pipe 46 (for example, a state where the outer ends of the connecting pipe 46 and the connecting member 42 are matched), the connecting pipe 46 and the connecting member 42 are formed. The upper and lower through holes 42a and 46a overlap, for example, on the left and right outer sides of the ground member 43, and a predetermined locking pin 47 is inserted into each of the upper and lower through holes 42a and 46a, so that the connecting member 42 and the ground member 43 are in the assembled state. It is connected so that it cannot be inserted and removed.

係止ピン47は、連結部材42及び連結パイプ46を貫通してさらに下方に突出して砂中に所定量差し込まれる。すなわち、係止ピン47は、ゴミ回収ステーション40の設置状態における所定位置からの移動を抑制する。そして、係止ピン47を取り外して連結パイプ46から連結部材42を抜き取れば、ゴミ回収ステーション40を左右側部構造体41と前後連結部材42とに分割可能である。   The locking pin 47 penetrates the connecting member 42 and the connecting pipe 46 and protrudes further downward and is inserted into the sand by a predetermined amount. That is, the locking pin 47 suppresses movement from a predetermined position in the installed state of the dust collection station 40. Then, by removing the locking pin 47 and extracting the connecting member 42 from the connecting pipe 46, the dust collection station 40 can be divided into the left and right side structure 41 and the front and rear connecting members 42.

図16,17に示すように、第二ビーチクリーナ50は、車両走行方向に沿って延びる複数(例えば三本)の縦部材51と、これらと略直交して幅方向(左右方向)に沿って延びる前後横部材52a,52bとを主として枠型のフレーム53を形成し、該フレーム53の前部には後述のキール54及びスクレーパ55を、後部には後述の網体56をそれぞれ備えてなる。なお、第二ビーチクリーナ50も左右対称の構成を有している。   As shown in FIGS. 16 and 17, the second beach cleaner 50 includes a plurality of (for example, three) vertical members 51 extending along the vehicle traveling direction, and along the width direction (left-right direction) substantially orthogonal thereto. The extending front and rear lateral members 52a and 52b mainly form a frame-shaped frame 53. A front portion of the frame 53 is provided with a keel 54 and a scraper 55 which will be described later, and a net 56 which will be described later. The second beach cleaner 50 also has a symmetrical configuration.

In the front part of the vertical member 51, the front and rear center parts thereof are gently bent, so that the front half part of the front part is provided to be inclined slightly upward. Hereinafter, the front first half of the vertical member 51 is referred to as a front inclined portion 57. On the other hand, the rear end portion of the vertical member 51 is provided curved upward. The vertical member 51 may be made of a square steel pipe.

この縦部材51が側面視で重なるように左右に複数並置され、その前端を左右方向に沿って延びる例えば角形鋼管からなる前横部材52aに後方から突き当てて結合されると共に、後端を左右方向に沿って延びる例えば円形鋼管からなる後横部材52bに下方から突き当てて結合される。これら各縦部材51及び横部材52a,52bを主とする前記フレーム53は、上面視で略正方形状に形成される。なお、フレーム53の左右幅は前記第一ビーチクリーナ20におけるフレーム22の左右幅と略同一とされる。   A plurality of the vertical members 51 are juxtaposed side by side so as to overlap in a side view, and the front ends of the vertical members 51 are abutted from the rear to a front horizontal member 52a made of, for example, a square steel pipe extending in the left-right direction. The rear transverse member 52b made of, for example, a circular steel pipe extending along the direction is abutted and coupled from below. The frame 53 mainly including the vertical members 51 and the horizontal members 52a and 52b is formed in a substantially square shape in a top view. The horizontal width of the frame 53 is substantially the same as the horizontal width of the frame 22 in the first beach cleaner 20.

左右中央の縦部材51と左右両側の縦部材51とのそれぞれの間には、これらの前部傾斜部57と側面視で重なるように傾斜したスクレーパフレーム58が左右に複数(例えば三本)並設される。スクレーパフレーム58は縦部材51と同径の円形鋼管(角形鋼管でもよい)からなり、その前端を前横部材52aに後方から突き当てて結合される一方、後端は何れの部材にも結合されない自由端とされる。なお、各スクレーパフレーム58と左右中央の縦部材51とはほぼ等間隔に並ぶのに対し、左右最外側のスクレーパフレーム58と左右両側の縦部材51とは間隔を狭めて配置される。   Between each of the vertical members 51 at the center of the left and right and the vertical members 51 on both the left and right sides, a plurality of (for example, three) scraper frames 58 that are inclined so as to overlap with the front inclined portions 57 in a side view. Established. The scraper frame 58 is formed of a circular steel pipe (or a square steel pipe) having the same diameter as that of the vertical member 51, and the front end of the scraper frame 58 is abutted against the front horizontal member 52a from the rear, and the rear end is not connected to any member. The free end. The scraper frames 58 and the left and right central vertical members 51 are arranged at almost equal intervals, whereas the left and right outermost scraper frames 58 and the left and right vertical members 51 are arranged with a small interval.

各縦部材51の前部傾斜部57及び各スクレーパフレーム58には、第二ビーチクリーナ50の牽引走行時に砂及び比較的小さなゴミ(飲料容器、紙屑、タバコの吸殻等)を掻き上げる巻き上げ部としてのキール54及びスクレーパ55が取り付けられる。
図19,20を併せて参照し、キール54は、縦部材51の前部傾斜部57の後部及び各スクレーパフレーム58の後部に着脱可能に取り付けられるもので、前部傾斜部57又はスクレーパフレーム58の下部外面に整合するように湾曲した板状部材61と、側面視で上方に開放するコ字状をなしてその両辺部が板状部材61を貫通するコ字状ピン62と、左右方向と略直交する板状をなして板状部材61の下端縁から下方に向けて延出するキール本体63とを有してなる。
The front inclined portion 57 of each vertical member 51 and each scraper frame 58 serve as a wind-up portion that scoops up sand and relatively small dust (beverage containers, paper waste, cigarette butts, etc.) when the second beach cleaner 50 is pulled. A keel 54 and a scraper 55 are attached.
19 and 20, the keel 54 is detachably attached to the rear portion of the front inclined portion 57 of the vertical member 51 and the rear portion of each scraper frame 58, and the front inclined portion 57 or the scraper frame 58 is attached.

The rear ski support pipe 77 is made of, for example, a square steel pipe that penetrates the extension frame 75 in the vertical direction, and the leg member 78 made of the same square steel pipe in the rear ski leg 76 can be inserted and supported. The rear ski leg 76 has the same configuration and function as the front ski leg 71, and a leg member 78 is erected on the rear ski plate 79.

後スキー支持パイプ77には単一の左右貫通孔77aが形成されると共に、該左右貫通孔77aに対応する左右貫通孔78aが脚部材78に上下に複数(例えば四つ)形成され、該左右貫通孔78aの何れかをスキー支持パイプの左右貫通孔77aに重ねてこれらに所定の係止ピン等を差し込むことで、後スキー脚76に対するフレーム53後部の高さが決定され、もって第二ビーチクリーナ50後部の地上高が所定高さに設定される(すなわち、第二ビーチクリーナ50後部の地上高を調整可能である。)。なお、左右前スキー脚71の前スキー板74外側端間の左右幅は、フレーム53の左右幅と略同一とされ、左右後スキー脚76の後スキー板79外側端間の左右幅は、フレーム53の左右幅よりも狭くされる。   A single left and right through hole 77a is formed in the rear ski support pipe 77, and a plurality of (for example, four) right and left through holes 78a corresponding to the left and right through holes 77a are formed vertically on the leg member 78. The height of the rear portion of the frame 53 with respect to the rear ski leg 76 is determined by overlapping any of the through holes 78a with the left and right through holes 77a of the ski support pipe and inserting predetermined locking pins or the like into these. The ground clearance at the rear of the cleaner 50 is set to a predetermined height (that is, the ground clearance at the rear of the second beach cleaner 50 can be adjusted). The left and right width between the outer ends of the front ski plate 74 of the left and right front ski legs 71 is substantially the same as the left and right width of the frame 53, and the left and right width between the outer ends of the rear ski plates 79 of the left and right rear ski legs 76 is 53 is made narrower than the lateral width of 53.

フレーム53前後の左右外側には、その外側端から左右外方に向けて張り出す前後リフトアーム81a,81bがそれぞれ設けられる。各リフトアーム81a,81bは、例えば上面視で横長の方形状をなす枠型のもので、その左右中間部は略水平とされ、かつ左右内側部が斜め下内側に、左右外側部が斜め下外側にそれぞれ屈曲形成される。これら各リフトアーム81a,81bの外側端間の左右幅は、ゴミ回収ステーション40の左右側部構造体41間の左右幅に対して広く(換言すれば、第一ビーチクリーナ20における左右リフトアーム39の外側端間の左右幅と略同一とされ)、第二ビーチクリーナ50が左右側部構造体41間に進入した際には、各リフトアーム81a,81bが左右側部構造体41に乗り上げることで、第二ビーチクリーナ50が所定量リフトアップされる。   Front and rear lift arms 81a and 81b are provided on the left and right outer sides of the front and rear sides of the frame 53 so as to project from the outer end toward the left and right sides. Each of the lift arms 81a and 81b is a frame-shaped frame having a horizontally long shape when viewed from the top, for example. The left and right middle portions are substantially horizontal, the left and right inner portions are obliquely inward and the left and right outer portions are obliquely downward. Each bend is formed outward. The left and right widths between the outer ends of the lift arms 81a and 81b are wider than the left and right widths between the left and right side structures 41 of the garbage collection station 40 (in other words, the left and right lift arms 39 of the first beach cleaner 20). When the second beach cleaner 50 enters between the left and right side structures 41, the lift arms 81 a and 81 b ride on the left and right side structures 41. Thus, the second beach cleaner 50 is lifted up by a predetermined amount.

ゴミ回収ステーション40において第二ビーチクリーナ50が前述の如くリフトアップされた際には、フレーム53後部の網体56が所定高さまで上昇し、該網体56をその左側のヒンジ82を介して回動させることで(図18参照)、網体56内に集められたゴミの回収作業を容易に行うことが可能となる。なお、第二ビーチクリーナ50においては、リフトアップさせない接地状態においても前記ゴミ収集作業を行うことが可能である。   When the second beach cleaner 50 is lifted up at the garbage collection station 40 as described above, the net 56 at the rear of the frame 53 rises to a predetermined height, and the net 56 is rotated through the hinge 82 on the left side. By moving it (see FIG. 18), it becomes possible to easily collect the dust collected in the net 56. In the second beach cleaner 50, it is possible to perform the dust collection work even in a ground contact state where the lift-up is not performed.

図21,22を併せて参照し、フレーム53左側の後リフトアーム81bには、網体56の左側部を回動自在に支持するヒンジ82の一部を構成する後ヒンジブラケット83が設けられる。後ヒンジブラケット83は、後リフトアーム81b基端側の前後に渡るもので、その前後端には上方に起立する前後壁84を有し、該前後壁84の先端側にはヒンジ軸82a用の前後貫通孔84aを形成してなる。前後壁84間には、後ヒンジブラケット83に対応して網体56左側に設けられた後ヒンジパイプ85が配置され、該後ヒンジパイプ85が前後方向に沿うヒンジ軸82aを介して後ヒンジブラケット83に回動自在に軸支される。   Referring to FIGS. 21 and 22, the rear lift arm 81 b on the left side of the frame 53 is provided with a rear hinge bracket 83 that constitutes a part of the hinge 82 that rotatably supports the left side portion of the net 56. The rear hinge bracket 83 extends in the front-rear direction of the rear end side of the rear lift arm 81b, and has a front-rear wall 84 standing upward at the front-rear end, and a front end side of the front-rear wall 84 for the hinge shaft 82a. A front and rear through hole 84a is formed. A rear hinge pipe 85 provided on the left side of the mesh body 56 corresponding to the rear hinge bracket 83 is disposed between the front and rear walls 84, and the rear hinge pipe 85 is connected to the rear hinge bracket 82 via a hinge shaft 82a along the front and rear direction. 83 is rotatably supported by the shaft 83.

また、上記後リフトアーム81bのやや前方には、該リフトアーム81bに対して左右幅を抑えた枠型の支持アーム86が設けられ、該支持アーム86には、前記後ヒンジブラケット83と同様の構成を有する前ヒンジブラケット87が支持される。前ヒンジブラケット87の前後壁88にはヒンジ軸82a用の前後貫通孔88aが形成される。前後壁88間には、前ヒンジブラケット87に対応して網体56左側に設けられた前ヒンジパイプ89が配置され、該前ヒンジパイプ89が前後方向に沿うヒンジ軸82aを介して前ヒンジブラケット87に回動自在に支持される。なお、各ヒンジパイプ85,89及びヒンジ軸82aは互いに同軸上に設けられる。   Further, a frame-shaped support arm 86 having a lateral width reduced with respect to the lift arm 81b is provided slightly in front of the rear lift arm 81b. The support arm 86 has the same structure as that of the rear hinge bracket 83. A front hinge bracket 87 having a configuration is supported. The front and rear walls 88 of the front hinge bracket 87 are formed with front and rear through holes 88a for the hinge shaft 82a. A front hinge pipe 89 provided on the left side of the net 56 corresponding to the front hinge bracket 87 is disposed between the front and rear walls 88, and the front hinge pipe 89 is connected to the front hinge bracket via a hinge shaft 82a along the front and rear direction. 87 is rotatably supported. The hinge pipes 85 and 89 and the hinge shaft 82a are provided coaxially with each other.

図16,17に示すように、網体56は、前方及び上方に開放する箱型をなし、例えば鋼管を主とする枠型のフレームに所定サイズの網目を有する金網を取り付けてなる。この網体56が、前後方向ではフレーム53前後中央よりもやや前方となる位置からフレーム53後端部近傍に至るまで、左右方向ではフレーム53と略同一の左右幅を有するように設けられる。ここで、網体56の前端位置は、各キール54及びスクレーパ55が巻き上げた砂及びゴミを良好に捕集可能とするべく、各キール54の後端近傍すなわち各スクレーパ55近傍から後方に100〜300mm程離間する。より好ましくは、網体56の前端位置は、各キール54の後端近傍から後方に250mm程離間するのがよい。   As shown in FIGS. 16 and 17, the net body 56 has a box shape that opens forward and upward, and is formed by attaching a wire net having a mesh of a predetermined size to a frame type frame mainly composed of a steel pipe, for example. The net 56 is provided so as to have substantially the same left-right width as the frame 53 in the left-right direction from a position slightly forward of the front-rear center of the frame 53 to the vicinity of the rear end of the frame 53 in the front-rear direction. Here, the position of the front end of the net 56 is 100 to the rear from the vicinity of the rear end of each keel 54, that is, from the vicinity of each scraper 55, so that the sand and dust wound up by each keel 54 and the scraper 55 can be collected well. Separate about 300 mm. More preferably, the front end position of the net 56 is spaced apart from the vicinity of the rear end of each keel 54 by about 250 mm.

図18を併せて参照し、網体56は、上面視で横長の長方形状をなす底壁部92と、該底壁部92の後縁から略垂直に立ち上がる後壁部93と、底壁部92の両側縁から上側ほど左右外側に位置するようにやや傾斜して立ち上がる左右側壁部94とを有してなる。後壁部93及び左右側壁部94は、各キール54及びスクレーパ55が巻き上げたゴミを底壁部92上に収集可能とするべく、底壁部92の周囲を前側のみ開放して取り囲む囲い部91を形成する。   Referring also to FIG. 18, the net 56 includes a bottom wall portion 92 that has a horizontally long rectangular shape in a top view, a rear wall portion 93 that rises substantially vertically from the rear edge of the bottom wall portion 92, and a bottom wall portion. The left and right side wall portions 94 rise up slightly inclined so as to be positioned on the left and right outer sides from the both side edges of 92. The rear wall portion 93 and the left and right side wall portions 94 open and surround the periphery of the bottom wall portion 92 only on the front side so that the dust rolled up by the keels 54 and the scraper 55 can be collected on the bottom wall portion 92. Form.

底壁部92の前部はやや前下がりに傾斜する傾斜部92aとされ、該傾斜部92aよりも後方となる部位は略水平な水平部とされる。この水平部は、左右方向に沿う横部材を境に前水平部92bと後水平部92cとに区画される。
ここで、底壁部92の傾斜部92aには網目サイズ25mmの金網が装着され、前水平部92bには網目サイズ12mmの金網が装着され、後水平部92cには網目サイズ8mmの金網が装着される。
The front portion of the bottom wall portion 92 is an inclined portion 92a that is inclined slightly forwardly downward, and the portion that is behind the inclined portion 92a is an approximately horizontal horizontal portion. The horizontal portion is divided into a front horizontal portion 92b and a rear horizontal portion 92c with a horizontal member extending in the left-right direction as a boundary.
Here, a wire mesh having a mesh size of 25 mm is attached to the inclined portion 92a of the bottom wall portion 92, a wire mesh having a mesh size of 12 mm is attached to the front horizontal portion 92b, and a wire mesh having a mesh size of 8 mm is attached to the rear horizontal portion 92c. Is done.

このように、底壁部92の金網の網目サイズを前側ほど粗く設定することで、各キール54及びスクレーパ55が巻き上げる砂の内、比較的重量のある湿気を含んだ砂等は、底壁部92後側まで至らないことから、底壁部92前側の傾斜部92aにおける粗目の金網を通じて、目詰まり等を起こすことなく良好にふるい落とされる。一方、比較的軽量の乾いた砂等は、ゴミと共に底壁部92後側の水平部まで至り、これに装着される中目及び細目の金網を通じて前記砂等がふるい落とされると共に、前記ゴミは網目から脱落することなく良好に補集される。なお、各金網は、網目サイズ6,8,10,12,25mm程の範囲で適宜交換可能とされる。   In this way, by setting the mesh size of the wire mesh of the bottom wall portion 92 as coarse as the front side, among the sand rolled up by each keel 54 and the scraper 55, sand containing relatively heavy moisture, etc. Since it does not reach the rear side of the 92, it is satisfactorily screened without causing clogging or the like through the coarse wire net in the inclined portion 92a on the front side of the bottom wall portion 92. On the other hand, the relatively light dry sand and the like reach the horizontal portion on the rear side of the bottom wall portion 92 together with the dust, and the sand and the like are screened through the middle and fine wire nets attached thereto. Good collection without dropping off the mesh. Each wire mesh can be appropriately replaced within a range of mesh sizes of 6, 8, 10, 12, 25 mm.

網体56の側壁部94は、底壁部92両側縁の上方に側面視で前後に長い長方形状の側壁本体94aを形成すると共に、該側壁本体94a後側の上方には側面視台形状の後部突出部94bを形成してなる。側壁本体94a及び後部突出部94bの後辺部は側面視略垂直をなして直線状に連なり、これら各後辺部を側辺部として網体56の後壁部93が設けられる。側壁部94(後部突出部94b)の上辺部と後壁部93の上辺部とは略同一高さとされる。   The side wall portion 94 of the net 56 is formed with a rectangular side wall main body 94a that is long in the front-rear direction in the side view above the both side edges of the bottom wall portion 92, and has a trapezoidal shape in the side view above the rear side of the side wall main body 94a. A rear protrusion 94b is formed. The rear side portions of the side wall main body 94a and the rear projecting portion 94b are arranged in a straight line substantially perpendicular to the side view, and the rear wall portion 93 of the net 56 is provided with these rear side portions as side portions. The upper side part of the side wall part 94 (rear protrusion part 94b) and the upper side part of the rear wall part 93 are substantially the same height.

網体56の左側壁部94の前後には、その側壁本体94aの中段及び下段のフレーム部材に跨るように前後ヒンジプレート95a,95bが設けられる。各ヒンジプレート95a,95bは側面視略正方形状をなす板状のもので、その外縁部分及び対角線部分を切り残すように適宜肉抜きが施されると共に、その前後縁部が左右内側に屈曲して補強フランジを形成する。各ヒンジプレート95a,95bの外側面には、前後ヒンジパイプ85,89がそれぞれ一体に接合されている。   Front and rear hinge plates 95a and 95b are provided in front of and behind the left side wall 94 of the net 56 so as to straddle the middle and lower frame members of the side wall body 94a. Each of the hinge plates 95a and 95b is a plate having a substantially square shape when viewed from the side. To form a reinforcing flange. Front and rear hinge pipes 85 and 89 are integrally joined to the outer surfaces of the hinge plates 95a and 95b, respectively.

左右側壁部94の前部上側(左側壁部94においては前ヒンジプレート95aの上方)には、その上縁から上方に突出する持ち手96aが設けられる。持ち手96aは側面視で下方に開放するコ字状をなし、その上辺部を前後方向に沿わせると共に対応する側壁部94よりもやや外側に張り出すように傾斜して設けられる。また、後壁部93の左右上側には、その上縁から上方に突出する持ち手96bが設けられる。持ち手96bは後面視で下方に開放するコ字状をなし、その上辺部を左右方向に沿わせると共に後壁部93と略同一平面上に位置するように略垂直に設けられる。   On the front upper side of the left and right side wall portions 94 (above the front hinge plate 95a in the left side wall portion 94), a handle 96a protruding upward from its upper edge is provided. The handle 96a has a U-shape that opens downward in a side view, and is inclined so that its upper side extends along the front-rear direction and projects slightly outward from the corresponding side wall 94. Further, on the upper left and right sides of the rear wall portion 93, a handle 96b protruding upward from the upper edge thereof is provided. The handle 96b has a U-shape that opens downward when viewed from the rear, and is provided substantially vertically so that its upper side extends along the left-right direction and is positioned substantially on the same plane as the rear wall 93.

網体56の左側部は、前述の如くフレーム53の左側部に前記ヒンジ82を介して回動自在に連結支持されており、このような網体56の右側を上方に持ち上げるように前記ヒンジ82を介して網体56を回動させ、その底壁部92を略垂直にした起立状態とすれば、網体56内に集めたゴミが左側壁部94上に落下し、該左側壁部94沿いに前記ゴミが網体56外に排出される。   As described above, the left side portion of the mesh body 56 is rotatably connected to the left side portion of the frame 53 via the hinge 82, and the hinge 82 is lifted so that the right side of the mesh body 56 is lifted upward. If the net body 56 is rotated through the bottom wall portion 92 so that the bottom wall portion 92 is in an upright state, dust collected in the net body 56 falls on the left side wall portion 94, and the left side wall portion 94. The dust is discharged out of the net 56 along the way.

このとき、網体56の囲い部91の各部(少なくともヒンジ82と反対側の部位)に持ち手96a,96bを設けることで、網体56を回動させてのゴミの回収作業が容易になる。また、横長の網体56における一短辺側(左側)にヒンジ82を配置したことで、網体56を起立させる際の回動軸から操作部(右側の持ち手)までの長さが確保され、網体56の回動操作が容易になる。   At this time, by providing the handles 96a and 96b at each part (at least on the side opposite to the hinge 82) of the surrounding part 91 of the net 56, it is easy to collect dust by rotating the net 56. . In addition, since the hinge 82 is arranged on one short side (left side) of the horizontally long net 56, the length from the rotating shaft when raising the net 56 to the operation unit (right handle) is secured. Thus, the rotation operation of the net 56 is facilitated.

網体56の左側壁部94(換言すれば囲い部91のヒンジ82側の壁部)は、前記ゴミの排出を良好に行うべく板部材が装着された壁部とされる。網体56の左側壁部94の上縁部は、前記起立状態においてゴミ回収ステーション40の外側よりも左方に張り出すように設定され(図18参照)、ゴミ回収ステーション40の左方に隣接してゴミ収集容器を配置すれば、左側壁部94をスロープにして網体56内に収集したゴミを前記容器内に直接投入可能である。なお、網体56の右側壁部94及び後壁部93は、網体56内に投入されたゴミの脱落を防止するべく、例えば粗めの金網がそれぞれ装着された網部とされる。   The left side wall portion 94 of the mesh body 56 (in other words, the wall portion on the hinge 82 side of the enclosure portion 91) is a wall portion on which a plate member is mounted in order to favorably discharge the dust. The upper edge portion of the left side wall portion 94 of the net 56 is set so as to protrude to the left of the outside of the dust collection station 40 in the standing state (see FIG. 18), and is adjacent to the left side of the dust collection station 40. If the waste collection container is arranged, the waste collected in the net 56 can be directly thrown into the container with the left side wall portion 94 as a slope. Note that the right side wall portion 94 and the rear wall portion 93 of the net body 56 are, for example, net portions to which coarse metal nets are attached in order to prevent the dust thrown into the net body 56 from dropping off.

フレーム53における左右両側の縦部材51上には、網体56左右両側の前後端の位置決めを行う左右前端又は後端ストッパ97a,97bがそれぞれ設けられる。各ストッパ97a,97bは、網体56前端又は後端に当接する略垂直な位置規制面と、その上方に仰向けに傾斜して連なる回動ガイド面とを有し、例えばボルト等を用いて縦部材51に着脱可能に取り付けられる。   On the left and right vertical members 51 in the frame 53, left and right front ends or rear end stoppers 97a and 97b for positioning the front and rear ends of the net 56 on both left and right sides are provided. Each stopper 97a, 97b has a substantially vertical position restricting surface that contacts the front end or the rear end of the mesh body 56, and a rotation guide surface that is inclined upwardly and continuously above it. The member 51 is detachably attached.

左右前端ストッパ97aの位置規制面には、使用状態(底壁部92を略水平にしてフレーム53上に当接させた状態)にある網体56の前端両側が当接すると共に、左右後端ストッパ97bの位置規制面には、前記使用状態にある網体56の後端両側が当接し、もって網体56のフレームに対する前後方向での位置決めがなされる。また、網体56を回動させて前記起立状態から使用状態に戻す際には、その前後端両側が各ストッパ97a,97bのガイド面に案内され、フレーム53上の所定位置に網体56がスムースに戻される。   The position restricting surface of the left and right front end stopper 97a is in contact with both sides of the front end of the net 56 in use (a state where the bottom wall portion 92 is substantially horizontal and is in contact with the frame 53). The rear end side of the net 56 in use is in contact with the position restricting surface 97b, so that the net 56 is positioned in the front-rear direction with respect to the frame. Further, when the mesh body 56 is rotated to return from the standing state to the use state, both the front and rear ends are guided by the guide surfaces of the stoppers 97a and 97b, and the mesh body 56 is placed at a predetermined position on the frame 53. Returned to smooth.

なお、図23に示すように、各ストッパ97a,97bの縦部材51への取り付け位置を前後に移動可能としてもよい。このとき、例えば網体56左側の前後ヒンジパイプ85,89の長さを前後ヒンジブラケット83,87の前後壁84,88間の間隔よりも短くする等により、各ストッパ97a,97bの移動に応じて網体56も前後に移動可能となる。このように、網体56の前端位置を砂地に応じて容易に変更可能とすることで、第二ビーチクリーナ50におけるゴミ補集能力の向上を図ることができる。   As shown in FIG. 23, the positions where the stoppers 97a and 97b are attached to the vertical member 51 may be movable back and forth. At this time, for example, the length of the front and rear hinge pipes 85 and 89 on the left side of the net 56 is made shorter than the distance between the front and rear walls 84 and 88 of the front and rear hinge brackets 83 and 87, etc. Thus, the net 56 can also be moved back and forth. Thus, the dust collecting ability of the second beach cleaner 50 can be improved by making it possible to easily change the front end position of the net 56 according to the sand.

次に、上記各ビーチクリーナ20,50を用いて砂浜を清掃する際の手順の概略について説明する。
まず、図1に示す如くトレーラ13に搭載して運搬したゴミ回収ステーション40を砂浜上の所定位置へ設置する。ここで、図1においては、ゴミ回収ステーション40を一体に組み立てた状態でトレーラ13に搭載可能としているが、これを前述の如く各側部構造体41及び連結部材42に分割した状態で搭載するようにしてももちろんよく、この場合、トレーラ13に対する積み降ろしを含めたゴミ回収ステーション40の設置作業が容易になる。なお、図1におけるゴミ回収ステーション40は、前記フート部材45のみ取り外されている。
Next, an outline of a procedure for cleaning the sandy beach using each of the beach cleaners 20 and 50 will be described.
First, as shown in FIG. 1, a garbage collection station 40 mounted on the trailer 13 and transported is installed at a predetermined position on the sand beach. Here, in FIG. 1, the dust collection station 40 can be mounted on the trailer 13 in an assembled state, but this is mounted in a state of being divided into the side structure 41 and the connecting member 42 as described above. Of course, in this case, installation work of the garbage collection station 40 including loading and unloading with respect to the trailer 13 is facilitated. Note that only the foot member 45 is removed from the dust collection station 40 in FIG.

次いで、第一ビーチクリーナ20のサンドピン23の数や第二ビーチクリーナ50の各キール54及びスクレーパ55の砂中への沈み込み量等を決定する基準となる砂浜の硬さを測定する。この測定は、例えば所定サイズの鉄杭を砂浜上に所定高さから自由落下させ、その測定結果の平均値から砂浜の硬さを例えば三段階(柔らかい、標準、硬い)に評価することで行う。このように測定した砂浜の硬さや散在するゴミの状況等に応じて、サンドピン23の数、ウェイト34の重量、各スキー脚の取り付け高さ、及び各牽引部37,67への連結ロッド38の連結位置等を決定する。   Next, the hardness of the sand beach which is a reference for determining the number of sand pins 23 of the first beach cleaner 20 and the amount of each keel 54 and scraper 55 submerged in the sand of the second beach cleaner 50 is measured. This measurement is performed by, for example, allowing a steel pile of a predetermined size to fall freely on a sand beach from a predetermined height, and evaluating the sand beach hardness, for example, in three stages (soft, standard, and hard) from the average value of the measurement results. . The number of sand pins 23, the weight of the weight 34, the height of each ski leg, and the connecting rod 38 to the traction portions 37 and 67 are determined according to the hardness of the sandy beach and the state of scattered dust. Determine the connection position.

次いで、トレーラ13から第一ビーチクリーナ20を降ろし、上記砂浜の硬さの測定結果に基づく設定を施した後、該第一ビーチクリーナ20を車両1により牽引して砂浜上を一定速度で走行させる。このときの車両1及び第一ビーチクリーナ20の走行軌跡は、図24に示すように、砂地上の所定範囲内において、略正方形状に旋回しつつその旋回位置を移動させるもので、前記所定範囲をむらなく確実に清掃可能とされる。第一ビーチクリーナ20は、各サンドピン23を砂中に食い込ませつつ砂浜上の比較的大きなゴミを回収することから、走行抵抗も比較的大きく、その走行速度は5〜10km/h程の低速に設定される。   Next, after the first beach cleaner 20 is lowered from the trailer 13 and set based on the measurement result of the hardness of the sandy beach, the first beach cleaner 20 is pulled by the vehicle 1 and travels on the sandy beach at a constant speed. . As shown in FIG. 24, the traveling trajectory of the vehicle 1 and the first beach cleaner 20 at this time moves the turning position while turning in a substantially square shape within a predetermined range on the sand surface. It can be surely cleaned without unevenness. Since the first beach cleaner 20 collects relatively large garbage on the sand beach while each sand pin 23 is biting into the sand, the running resistance is relatively large, and the running speed is as low as about 5 to 10 km / h. Is set.

上述の如く第一ビーチクリーナ20が砂浜上を走行し、そのフレーム22下に所定量のゴミが収集されると、第一ビーチクリーナ20が一旦ゴミ回収ステーション40に戻り、前記集めたゴミの回収作業が行われる。このとき、ゴミ回収ステーション40の左右側部構造体41間を車両1が通過した後に第一ビーチクリーナ20が左右側部構造体41間に進入すると、その左右リフトアーム39が左右側部構造体41に乗り上げて第一ビーチクリーナ20が所定量リフトアップされる(図13参照)。この状態で車両1及び第一ビーチクリーナ20を停止させ、砂地上に落下させたゴミの回収作業を行った後、再度車両1及び第一ビーチクリーナ20を走行させて前述のゴミ回収作業を繰り返す。   As described above, when the first beach cleaner 20 travels on the sand beach and a predetermined amount of garbage is collected under the frame 22, the first beach cleaner 20 returns to the garbage collection station 40 and collects the collected garbage. Work is done. At this time, when the first beach cleaner 20 enters between the left and right side structures 41 after the vehicle 1 passes between the left and right side structures 41 of the garbage collection station 40, the left and right lift arms 39 are moved to the left and right side structures. 41, the first beach cleaner 20 is lifted up by a predetermined amount (see FIG. 13). In this state, the vehicle 1 and the first beach cleaner 20 are stopped, and after collecting the dust dropped on the sand, the vehicle 1 and the first beach cleaner 20 are run again to repeat the above-described dust collecting operation. .

第一ビーチクリーナ20により所定範囲の清掃を行った後には、次に同一範囲に対して第二ビーチクリーナ50を牽引走行させることで、砂浜上の比較的小さなゴミの回収を行う。このように、第一ビーチクリーナ20の後に第二ビーチクリーナ50を用いることで、細かなゴミに対応するキール54、スクレーパ55、及び網体56等の破損が抑えられる。なお、第二ビーチクリーナ50の走行軌跡も第一ビーチクリーナ20と同様のものとする。また、第二ビーチクリーナ50は、その走行時には第一ビーチクリーナ20の作用により砂浜が掘り起こされて柔らかくなっており、かつ各キール54及びスクレーパ55により砂及びゴミを巻き上げる必要があることから、その走行速度は第一ビーチクリーナ20に対してやや速い15〜25km/h程に設定される。   After the predetermined range of cleaning is performed by the first beach cleaner 20, the second beach cleaner 50 is pulled to the same range to collect relatively small dust on the sand beach. Thus, by using the second beach cleaner 50 after the first beach cleaner 20, damage to the keel 54, the scraper 55, the net 56, and the like corresponding to fine dust can be suppressed. The traveling locus of the second beach cleaner 50 is the same as that of the first beach cleaner 20. Further, the second beach cleaner 50 is softened by digging up the sandy beach by the action of the first beach cleaner 20 during traveling, and it is necessary to wind up sand and dust by each keel 54 and scraper 55. The traveling speed is set to 15 to 25 km / h, which is slightly faster than the first beach cleaner 20.

第二ビーチクリーナ50が砂浜上を走行することで、比較的小さなゴミが砂と共に各キール54及びスクレーパ55により巻き上げられ、これらがフレーム53後部の網体56内に収集される。このとき、網体56の底壁部92前側から順に金網の網目サイズが細かくなるように設定したことで、収集したゴミが落下し難くかつ金網の目詰まりが抑えられる。   As the second beach cleaner 50 runs on the sandy beach, relatively small dust is rolled up by the keels 54 and the scraper 55 together with the sand, and these are collected in the net 56 at the rear of the frame 53. At this time, since the mesh size of the wire mesh is set to become smaller in order from the front side of the bottom wall portion 92 of the mesh body 56, collected dust is difficult to fall and clogging of the wire mesh is suppressed.

上述の如く第二ビーチクリーナ50が砂浜上を走行し、その網体56内に所定量のゴミが収集されると、第二ビーチクリーナ50が一旦ゴミ回収ステーション40に戻り、前記集めたゴミの回収作業が行われる。このとき、ゴミ回収ステーション40の左右側部構造体41間を車両1が通過した後に第二ビーチクリーナ50が左右側部構造体41間に進入すると、その前後の左右リフトアーム81a,81bが左右側部構造体41に乗り上げて第二ビーチクリーナ50が所定量リフトアップされる。この状態で車両1及び第二ビーチクリーナ50を停止させ、網体56を回動させて集めたゴミの回収作業を行った後、再度車両1及び第二ビーチクリーナ50を走行させて前述のゴミ回収作業を繰り返す。   As described above, when the second beach cleaner 50 travels on the sand beach and a predetermined amount of garbage is collected in the net 56, the second beach cleaner 50 returns to the garbage collection station 40, and the collected garbage is collected. Collection work is performed. At this time, when the second beach cleaner 50 enters between the left and right side structures 41 after the vehicle 1 passes between the left and right side structures 41 of the garbage collection station 40, the left and right lift arms 81a and 81b before and after the second beach cleaner 50 move left and right. The second beach cleaner 50 is lifted up by a predetermined amount after riding on the side structure 41. In this state, the vehicle 1 and the second beach cleaner 50 are stopped, the net 56 is rotated, and the collected dust is collected. Then, the vehicle 1 and the second beach cleaner 50 are run again, and the above-described dust is collected. Repeat the collection process.

以上説明したように、上記実施例におけるゴミ回収ステーション40は、左右一対の接地部材43のそれぞれに側面視山形の案内部材44を設けると共に、前記各接地部材43間をバー状の連結部材42で一体に連結してなり、牽引車両1に牽引されて砂地を走行してゴミを回収する各ビーチクリーナ20,50を乗り上げさせて、該各ビーチクリーナ20,50が集めたゴミの回収を可能とするものであって、前記連結部材42の端部と接地部材43とを着脱可能に連結する連結パイプ46を備えるものである。   As described above, the garbage collection station 40 in the above embodiment is provided with the mountain-shaped guide member 44 in the side view in each of the pair of left and right grounding members 43 and the bar-shaped coupling member 42 between the grounding members 43. The beach cleaners 20 and 50, which are integrally connected and are towed by the towing vehicle 1 and run on the sand and collect the garbage, can be picked up, and the garbage collected by the beach cleaners 20 and 50 can be collected. And a connecting pipe 46 that detachably connects the end of the connecting member 42 and the grounding member 43.

この構成によれば、接地部材43及び案内部材44を主とする側部構造体41と連結部材42とに分割可能とすることで、各分割体がそれぞれ平面的になり、分割後に嵩張り難く、各分割体の持ち運びやトレーラ13に対する積み降ろしがし易く、かつ分割体同士の組み付けもし易くなり、設置作業を容易にすることができる。   According to this configuration, by allowing the grounding member 43 and the guide member 44 to be divided into the main side structure 41 and the connecting member 42, each divided body becomes planar, and is difficult to be bulky after the division. In addition, it is easy to carry each segment and load / unload the trailer 13 and to assemble the segments, thereby facilitating the installation work.

また、上記ゴミ回収ステーション40においては、前記連結パイプ46は、前記連結部材42の端部を挿入可能な筒状であり、該連結パイプ46に連結部材42を挿入した状態で、これらを貫通する係止ピン47が差し込まれると共に、該係止ピン47が砂地に差し込まれることで、係止ピン47が連結部材42と連結パイプ46とを抜き差し不能に連結すると共に、ゴミ回収ステーション40の砂地に対する移動を抑制することができる。   In the garbage collection station 40, the connection pipe 46 has a cylindrical shape into which an end of the connection member 42 can be inserted, and penetrates through the connection pipe 42 with the connection member 42 inserted. When the locking pin 47 is inserted and the locking pin 47 is inserted into the sand, the locking pin 47 connects the connecting member 42 and the connecting pipe 46 so that they cannot be inserted and removed, and the dust collection station 40 is connected to the sand. Movement can be suppressed.
