Description

この発明は、汚泥掻寄装置に関する。 The present invention relates to a sludge scraping device.

矩形沈澱池は、矩形の短辺を前後の端壁とし長辺を幅方向に対向する左右の側壁とするとともに底壁を備えこの底壁の汚泥掻寄方向である前側の端壁側に汚泥ピットを備えて立体躯体構造としたものでなる。沈澱池のピットの上方に対応する前側の端壁が上流側とされてその上側には沈澱池外から導かれてきた汚水が導入される流入渠が設けられるとともに同流入渠の池内への出口に横断状に設けた多孔状の整流壁(板)の整流孔を通じて汚水を整流化しながらごく緩徐な流れにして沈澱池内に送り込みそのまま下流側へゆっくりと流すことにより沈降を促進して底壁上に汚泥を沈澱させるようにしてある。底壁上に沈澱した汚泥は、汚泥掻寄装置により汚泥ピットまで掻き寄せられ回収されピット外に排出されるようにしてある。
前記汚泥掻寄装置には種々のものがあるが、ここではその一例として特許文献1を示す。
The rectangular sedimentation pond has the short side of the rectangle as the front and rear end walls and the long side as the left and right side walls facing each other in the width direction, and also has a bottom wall, and sludge is provided on the front end wall side, which is the sludge approaching direction of the bottom wall. It has a three-dimensional skeleton structure with pits. The front end wall corresponding to the upper part of the pit of the sedimentation basin is regarded as the upstream side, and an inflow culvert for introducing sewage guided from the outside of the sedimentation basin is provided on the upper side, and the outlet of the inflow basin into the pond While rectifying sewage through the rectifying holes of the porous rectifying wall (plate) provided in a transverse manner, the sludge is sent into the sedimentation basin in a very slow flow and slowly flows downstream as it is to promote sedimentation on the bottom wall. The sludge is settled in the water. The sludge that has settled on the bottom wall is scraped up to the sludge pit by a sludge scraping device, collected, and discharged to the outside of the pit.
There are various sludge scraping devices, and Patent Document 1 is shown here as an example.

特開2017−148791JP 2017-148791

特許文献1に開示された汚泥掻寄装置は、池底の池幅中央を通るようにガイドレールを固定して備え、このガイドレールには、前後一対ずつの車輪を介して進退するようにした機体を備える。この機体は、丸パイプを長尺状にした機体本体を備え、その機体本体の前端には前取付台がまた後端には後取付台が設置され、それぞれに左右一対の軸受を固定するとともに、これらにスクレーパ軸を介して前後に汚泥スクレーパを備えている。そして、汚泥スクレーパは、例えば、リンクチェーン駆動方式により後退したのちに垂直な汚泥掻寄姿勢とされて機体とともに前進されて前方のピット方向に汚泥を掻き寄せることでピットに汚泥を落とし込むようにされ、前進して掻寄を終えると汚泥スクレーパは掻き戻しをしない持上状態にしてその状態を保ったまま後方の元の位置まで復帰運動をするようになっている。
しかし、前記特許文献1における駆動手段は、駆動ホイール付き駆動源とヘッド側ホイールとテール側ホイールを回転駆動系として有し、これらに伝導条材を巻き掛けてその端部間には連結ロッドが連結されている。そして、装置後部においては、丸パイプ状の機体(本体)の後部に後取付台を結合し、その上に左右一対の軸受を備え、この軸受を介してスクレーパ軸を支持して汚泥スクレーパを取り付け、さらにスクレーパ軸の周りには後レバー(後軸周りレバー)が前下がり状に突設されて連結ロッド(進退切換連動材)の後端が連結されている。
こうした構造のものでは、汚泥スクレーパが持ち上がったままハンチ上に戻され、さらに連結ロッド(進退切換連動材)の前進方向への切換により汚泥スクレーパがハンチを掻き落とすようにスイングすることによりハンチ上に溜まった汚泥を前下方向に掻き降ろすようにすることが汚泥を残さずピット側へ掻き寄せることから水質向上につながるのである。そのためには、汚泥スクレーパを一杯に戻す必要がある訳であるが、従来の方式では、テール側ホイールをハンチ側に一杯まで奥寄りに配置したとしても、連結ロッド(進退切換連動材)の末端がテール側ホイールの周位点を越えるところまでは後退することができず、従って、汚泥スクレーパは、手前までしか充分余裕をもって後退させることができなかった。
The sludge scraping device disclosed in Patent Document 1 is provided with a guide rail fixed so as to pass through the center of the pond width at the bottom of the pond, and the guide rail is moved forward and backward via a pair of front and rear wheels. Equipped with an aircraft. This machine is equipped with a body with a long round pipe, and a front mount is installed at the front end of the body and a rear mount is installed at the rear end, and a pair of left and right bearings are fixed to each. , These are equipped with sludge scrapers in the front and rear via a scraper shaft. Then, for example, the sludge scraper is set to a vertical sludge scraping posture after retreating by a link chain drive system, is advanced together with the aircraft, and is made to drop sludge into the pit by scraping sludge toward the front pit. When the sludge scraper advances and finishes scraping, the sludge scraper is put into a lifting state without scraping back, and while maintaining that state, it returns to the original position behind.
However, the drive means in Patent Document 1 has a drive source with a drive wheel, a head-side wheel, and a tail-side wheel as a rotary drive system, and a conductive strip is wound around them, and a connecting rod is formed between the ends thereof. It is connected. Then, at the rear of the device, a rear mounting base is connected to the rear of the round pipe-shaped body (main body), a pair of left and right bearings are provided on the rear mounting base, and a sludge scraper is mounted by supporting the scraper shaft via these bearings. Further, a rear lever (lever around the rear shaft) is projected so as to descend forward around the scraper shaft, and the rear end of the connecting rod (advance / retreat switching interlocking material) is connected.
In such a structure, the sludge scraper is returned to the haunch while being lifted, and the sludge scraper swings on the haunch by switching the connecting rod (advance / retreat switching interlocking material) in the forward direction so as to scrape off the haunch. By scraping the accumulated sludge downward and forward, the sludge is scraped toward the pit side without leaving any sludge, which leads to improvement in water quality. For that purpose, it is necessary to return the sludge scraper to full, but in the conventional method, even if the tail side wheel is placed as far back as possible on the haunch side, the end of the connecting rod (advance / retreat switching interlocking material) However, it was not possible to retract beyond the peripheral point of the tail wheel, so the sludge scraper could only retract to the front with sufficient margin.

この発明は、上記問題を解決しようとするもので、後部の汚泥スクレーパが復帰したときにハンチ上の汚泥を掻き落とすに充分なところまで後退可能とされることでハンチ上に沈降した汚泥は何時も汚泥スクレーパで掻き落とされるとともにピットへと掻き寄せることができて水質向上の一助となるようにした汚泥掻寄装置を提供することを目的とする。 The present invention is to solve the above problem, and when the rear sludge scraper returns, the sludge settled on the haunch can always be retracted to a sufficient extent to scrape off the sludge on the haunch. It is an object of the present invention to provide a sludge scraping device that can be scraped off by a sludge scraper and can be scraped into a pit to help improve water quality.

Reference numeral 13 denotes a SUS machine body, which has two front and rear body bodies 14, 14 and a front mounting base 15, an intermediate mounting base 16, and a rear mounting base 17.
The machine body 14 may be a round pipe, but in consideration of the fact that sludge tends to collect on the upper peripheral surface of the round pipe, in this embodiment, as shown in FIG. 4, a long quadrangle made of SUS is used. The basic rule is that one vertex (ridge angle) is directly above. In particular, the airframe body 14 has side bodies 20 and 20 made of a pair of left and right angle members, and is divided into left and right parts, and is provided with projecting pieces 21 that also serve as reinforcement above and below the side bodies 20 and 20. ing. The left and right projecting pieces 21 and 21 are integrally arranged so as to face each other over the entire length of the side body 20 with a slight gap, but they are connected via a joining spacer 22 ... Except for a part in the front-rear direction between them. ing. On the upper side, the front and rear two front and rear switching upper protrusions 59 and 59, which will be described later, advance and retreat.
On the lower side, the front and rear forward / backward switching lower protrusions 64 and 64, which will be described later, are the front and rear, respectively.
Corresponds to this. All of the upper and lower sides except for them are in a state of being joined by the joining spacer 22 ... With the fastener 23, but in particular, the lower projecting pieces 64 and 64 move forward and backward.

側体20の前後各端部には、四角形をした端板25が設けられ、止着具26を介して後述する端取付枠に脱着自在に取り付けられるようになっている。端取付枠の止着具26の通される孔はボルトを移動調節可能な大孔とされている。
前後各機体本体14の内部には、機体本体14よりも少し小さい四角筒型をした進退切換連動材28が機体本体14と同芯状をなすようにして前後に進退自在に設けられている。
A quadrangular end plate 25 is provided at each of the front and rear ends of the side body 20 so that the side body 20 can be detachably attached to an end mounting frame described later via a fastener 26. The hole through which the fastener 26 of the end mounting frame is passed is a large hole in which the bolt can be moved and adjusted.
Inside each of the front and rear body 14, a square cylinder-shaped advance / retreat switching interlocking member 28, which is slightly smaller than the body 14, is provided so as to be concentric with the body 14 so as to be able to move forward and backward.

前取付台15および中間取付台16は同じ構造であり後取付台17は一部(取付台本体の向き)を除いて前記取付台15,16と同じ構造であるので、これらは全て同じ構造であるとして以下に説明する。

前記端取付枠30は、図4の右上欄に示すように溝開口を外側に向けたものにしてもよいし、その下欄に示すように四角筒状にしてもよい。これらの場合、後述する取付台本体37は溝内に挿し込んで固着するのでなく、端取付枠30の内側面に固着したものにする。
The front mounting base 15 and the intermediate mounting base 16 have the same structure, and the rear mounting base 17 has the same structure as the mounting bases 15 and 16 except for a part (direction of the mounting base main body), so that they all have the same structure. If there is, it will be described below.
The front mounting base 15 has a pair of left and right end mounting frames 30. The end mounting frame 30 has a groove-shaped frame shape having an outer side vertical plate portion 31 and front and rear vertical plate portions 32, 32 integrally, and a scraper shaft passes through the upper portion of the side vertical plate portion 31.

Downward steady rest members 35, 35 are fixed to the left and right ends of the bottom receiving plate 34.
The end mounting frame 30 may have a groove opening facing outward as shown in the upper right column of FIG. 4, or may have a square tubular shape as shown in the lower column thereof. In these cases, the mounting base body 37, which will be described later, is not inserted into the groove and fixed, but is fixed to the inner surface of the end mounting frame 30.

37は取付台本体で、同本体37は、上面板38と立面板39とを有するアングル型とされて、その左右端部が両端取付枠30,30の底受板34より下側にあるようにして固着されている。立面板39の左右間下部39aは下向きに広く伸びており、その部分に前記端板25が取り付けられるようになっている。底受板34は省略して取付台本体37の上面板38を底受板34に代えて構成してもよい。 Reference numeral 37 denotes a mounting base body, and the main body 37 is an angle type having a top plate 38 and an elevation plate 39 so that the left and right ends thereof are below the bottom receiving plates 34 of the mounting frames 30 and 30 at both ends. It is fixed. The lower portion 39a between the left and right sides of the elevation plate 39 extends widely downward, and the end plate 25 is attached to that portion. The bottom receiving plate 34 may be omitted, and the upper surface plate 38 of the mounting base body 37 may be replaced with the bottom receiving plate 34.

41は固定蓋で、扁平溝型材でなって端取付枠30の上端にタップねじなどの止着具42により固定されるようになっている。この固定蓋41の左右にも上振れ止め材43の一対が固着されている。45は車輪で、端取付枠30のスクレーパ軸下方に対応する位置の下部内に車軸46を介して回転自在に取り付けられている。 Reference numeral 41 denotes a fixing lid, which is made of a flat groove type material and is fixed to the upper end of the end mounting frame 30 by a fastener 42 such as a tap screw. A pair of upper steady rest members 43 are also fixed to the left and right sides of the fixing lid 41. Reference numeral 45 denotes a wheel, which is rotatably mounted via the axle 46 in the lower portion of the end mounting frame 30 at a position corresponding to the lower side of the scraper shaft.

50は1本の丸パイプでなるSUS製のスクレーパ軸で、池幅よりは少し短めとされ、その中央2個所には左右の底受板34,34上に合致するようにして上下分割合わせ型の樹脂ブロック製軸受51が装備されるようになっている。軸受51は、特許公報1に示すボルト止め式のものに比べてボルト止め構造としない分可成り短くコンパクトに造られている。軸受51の数は前部に左右2個ずつで合計4個であり、後部も4個で、さらに中間には最低4個、スクレーパが中間に多い場合は8個あるいは12個などのように全体として非常に個数が多くなることから前記のように特殊樹脂を小さくコンパクト化することは非常にコストダウンにつながる。スクレーパ軸50の直径(65mm)より前後がそれぞれ20〜30mm長い程度の例えば、105ないし125mmの前後長とされる。 50 is a scraper shaft made of SUS made of one round pipe, which is slightly shorter than the width of the pond, and is divided into upper and lower parts so that it matches the left and right bottom bearing plates 34 and 34 at the two central points. The resin block bearing 51 of the above is equipped. The bearing 51 is made considerably shorter and more compact than the bolted type shown in Patent Publication 1 because it does not have a bolted structure. The number of bearings 51 is 4 on the left and 2 on the front, 4 on the rear, at least 4 in the middle, 8 or 12 if there are many scrapers in the middle, and so on. As the number of special resins becomes very large, making the special resin smaller and more compact as described above leads to a great cost reduction. The front-rear length is about 20 to 30 mm longer than the diameter (65 mm) of the scraper shaft 50, for example, 105 to 125 mm.

軸受51は底受板34の下振れ止め材35,35間に相当して嵌め込まれるようになっており、その嵌め込まれた軸受51は固定蓋41の取り付けにより上から押さえ付けられながら上振れ止め材43,43間で左右振れおよび前後振れ、上下振れなどないように位置規制されるものとなる。底受板34上面と端取付枠30の上端との内部高さは、軸受51の高さと基本的に同じかあるいは軸受51の方が微少に高い設定とされる。 The bearing 51 is fitted between the bottom steady rest members 35 and 35 of the bottom receiving plate 34, and the fitted bearing 51 is pressed from above by the attachment of the fixed lid 41 to prevent the upward runout. The position is regulated between the materials 43 and 43 so as to prevent left-right runout, front-back runout, and up-down runout. The internal height of the upper surface of the bottom receiving plate 34 and the upper end of the end mounting frame 30 is basically the same as the height of the bearing 51, or the bearing 51 is set to be slightly higher.

スクレーパ軸50の回りには軸受51の左右動を規制するずれ止めリング52が左右一対溶接固定されている。また、スクレーパ軸50の下部には、汚泥スクレーパ53がまた上部には補助スクレーパ54が設けられるとともに仕切り板55が設けられている。スクレーパ軸50の左右の軸受51間に相当する中間位置には、軸周りレバー57が突設され、このレバー57に前端が連結された連動リンク58はその後端を進退切換上突片59に連結されている。 A pair of left and right anti-slip rings 52 that regulate the left-right movement of the bearing 51 are fixed by welding around the scraper shaft 50. A sludge scraper 53 is provided at the lower part of the scraper shaft 50, and an auxiliary scraper 54 is provided at the upper part, and a partition plate 55 is provided. An axial lever 57 is projected at an intermediate position corresponding to the left and right bearings 51 of the scraper shaft 50, and the interlocking link 58 having a front end connected to the lever 57 connects the rear end to the advance / retreat switching upper protrusion 59. Has been done.

進退切換上突片59は進退切換連動材28の上稜角部に突設されている。進退切換連動材28は、単一本でなりその外周側辺に滑動自在な樹脂製ライナー62を備えて機体本体14内で切換ストロークSのもとで進退滑動自在に装備されている。図1から図7は、進退切換連動材28は前進のため前側の機体本体14の前端(端板25)に先端が当たって前進力を機体に与えるようになっている。機体本体14は前取付台15と中間取付台16との間に1本連結され、中間取付台16と後取付台17との間にも次の1本が連結されている。中間取付台16の立面板39には、前後から端板25,25が連結されているが、その板面には進退切換連動材28が進退自在に通されるための通口(図示省略)が開けられている。後取付台17の取付台本体37は他の取付台のそれとは異なり立面板39が前側にくるようにして設けられている。後で説明する後部の池幅間中央の軸周りレバー57が復帰時に持ち上げ回転する際に干渉しないようにするためである。 The advance / retreat switching upper projecting piece 59 is projected from the upper ridge angle portion of the advancing / retreating switching interlocking member 28. The advancing / retreating switching interlocking member 28 is a single piece and is provided with a slidable resin liner 62 on the outer peripheral side thereof, and is slidably mounted in the machine body 14 under the switching stroke S. In FIGS. 1 to 7, the advance / retreat switching interlocking member 28 is adapted so that the tip of the advancing / retreating switching interlocking member 28 hits the front end (end plate 25) of the front body 14 for advancing to give a forward force to the airframe. One of the machine body 14 is connected between the front mounting base 15 and the intermediate mounting base 16, and the next one is also connected between the intermediate mounting base 16 and the rear mounting base 17. The end plates 25 and 25 are connected to the elevation plate 39 of the intermediate mounting base 16 from the front and rear, and the advancing / retreating switching interlocking member 28 is passed through the plate surface freely (not shown). Is open. The mounting base body 37 of the rear mounting base 17 is provided so that the elevation plate 39 is on the front side, unlike that of other mounting bases. This is to prevent the lever 57 around the axis at the center between the widths of the rear pond, which will be described later, from interfering with the lifting and rotating at the time of return.

進退切換連動材28の前部の上突片59の下方に対応する個所には、進退切換下突片64が突設され、その下端には前伝導アンカー65が取り付けられている。上突片59および下突片64はSUS製であるが、機体本体14に対して滑り易いように左右両面に樹脂板を重ね付けてもよい。前記前伝導アンカー65にはリンクチェーンやワイヤロープなどの伝導条材66の一端が連結されている。
伝導条材66は、ガイドレール7の先端に渡した受板68に配備した左右一対のヘッド側ホイール70,71のうち左側ホイール70を経由して上方の駆動部75へと導かれている。図2においてヘッド側ホイール70,71は実際にはガイドレール7の先端上に設けられているが、図面では後述する反転切換機構の作用部が同じ個所に図示されて重複表示になるのでそれを避けるため左側にずらせて表示してある。図1ではホイール70,71は実際の位置表示になっている。
A forward / backward switching lower protrusion 64 is projected at a position corresponding to the lower part of the upper protrusion 59 at the front portion of the advance / retreat switching interlocking member 28, and a front conduction anchor 65 is attached to the lower end thereof. Although the upper projecting piece 59 and the lower projecting piece 64 are made of SUS, resin plates may be laminated on both the left and right sides so as to be slippery with respect to the machine body 14. One end of a conductive strip 66 such as a link chain or a wire rope is connected to the front conductive anchor 65.
The conductive strip 66 is guided to the upper drive unit 75 via the left wheel 70 of the pair of left and right head side wheels 70 and 71 arranged on the receiving plate 68 passed to the tip of the guide rail 7. In FIG. 2, the head-side wheels 70 and 71 are actually provided on the tip of the guide rail 7, but in the drawing, the action part of the reversing switching mechanism described later is shown at the same place and the display is duplicated. It is displayed by shifting it to the left to avoid it. In FIG. 1, the wheels 70 and 71 are actual position displays.

駆動部(駆動手段の要部)75は、図18および図19にも図示されており、池上壁76上にモルタル基盤77を介して矩形枠状の駆動基台78を緩衝材79で緩衝作用するようにして固定して備える。駆動基台78内には池の左右に対応する側に一対の渡架板80を固定してその上に緩衝材79を介して受版81を高さ調節ボルト82にて高さ変更可能に取り付けてある。この受版81上には、減速機付きモーターである駆動源83がその底盤部を介して高さ調節可能な状態で取付けられている。 The drive unit (main part of the drive means) 75 is also shown in FIGS. 18 and 19, and the rectangular frame-shaped drive base 78 is cushioned by the cushioning material 79 on the pond wall 76 via the mortar base 77. Fix and prepare as you do. A pair of bridge plates 80 are fixed in the drive base 78 on the left and right sides of the pond, and the height of the receiving plate 81 can be changed by the height adjusting bolt 82 via the cushioning material 79. It is installed. A drive source 83, which is a motor with a speed reducer, is mounted on the plate 81 in a height-adjustable state via a bottom plate thereof.

85は駆動軸、86は駆動ホイールで、前記ヘッド側ホイールの左側のもの70を経由した伝導条材66は図2および図19の手前側から駆動ホイール86周りに掛けられ、その向こう側に回された伝導条材66はヘッド側ホイールの右側のもの71を経由して図1のテール側ホイール88に回されたのち図8および図9のように後連動リンク89に連結されている。ここで、後連動リンク89の後端は前記伝導条材66の端部に連結されている他に後軸周りレバー90の下端にも連結されている。 85 is a drive shaft, 86 is a drive wheel, and the conductive strip 66 via the one 70 on the left side of the head side wheel is hung around the drive wheel 86 from the front side of FIGS. 2 and 19, and is rotated to the other side. The conductive strip 66 is turned to the tail side wheel 88 of FIG. 1 via the one 71 on the right side of the head side wheel, and then connected to the rear interlocking link 89 as shown in FIGS. 8 and 9. Here, the rear end of the rear interlocking link 89 is connected to the end portion of the conductive strip 66 and also to the lower end of the lever 90 around the rear axle.

このように後連動リンク89の後端に伝導条材66の端部の他に後軸周りレバー90を平行関係に分けて連結したのは、次の理由による。
図14・図15は復帰前(終端より少し手前)時の状態をまた図16・図17は復帰終端時の様子を示す従来の比較例を示すものである。従来は、丸パイプの機体本体120にローラー121で進退切換連動材122を前後に進退駆動自在とし、その左端に伝導条材123の一端がまた右端には伝導条材123の他端(図示の部分)が接続される。この場合、進退切換連動材122はスクレーパ軸124周りの軸周りレバー125に後端手前部分が結合されるとともに、さらに進退切換連動材122の後端は後方へ伸びた形にされてその後端に伝導条材123が接続されたものとなっている。
The reason why the rear axle lever 90 is connected in parallel to the rear end of the rear interlocking link 89 in addition to the end of the conductive strip 66 is as follows.
14 and 15 show a state before the return (slightly before the end), and FIGS. 16 and 17 show a conventional comparative example showing the state at the end of the return. Conventionally, a roller 121 is used to drive the advancing / retreating switching interlocking member 122 back and forth on the body 120 of a round pipe, and one end of the conductive strip 123 is at the left end and the other end of the conductive strip 123 is at the right end (not shown). Part) is connected. In this case, the advancing / retreating switching interlocking member 122 has a rear end front portion coupled to an axial lever 125 around the scraper shaft 124, and the rear end of the advancing / retreating switching interlocking member 122 is further extended rearward to the rear end. The conductive strip 123 is connected.

こうした構造のものでは、汚泥スクレーパ126が持ち上がったままハンチ127上に戻され、さらに進退切換連動材122の前進方向への切換により汚泥スクレーパ126がハンチ127を掻き落とすようにスイングすることによりハンチ127上に溜まった汚泥を前下方向に掻き降ろすようにすることが汚泥を残さずピット側へ掻き寄せることから水質向上につながるのである。そのためには、汚泥スクレーパ126を図17に右端に示したように一杯に戻す必要がある訳であるが、従来の方式では、テール側ホイール128をハンチ127側に一杯まで奥寄りに配置したとしても、図16のように、進退切換連動材122の末端がテール側ホイール128の周位点aを越えるところまでは後退することができず、従って、汚泥スクレーパ126は、図17の手前bまでしか充分余裕をもって後退させることができなかった。 In such a structure, the sludge scraper 126 is returned onto the haunch 127 while being lifted, and the sludge scraper 126 swings so as to scrape off the haunch 127 by switching the advancing / retreating switching interlocking member 122 in the forward direction. By scraping down the sludge accumulated on the top in the forward and downward directions, the sludge is scraped toward the pit side without leaving any sludge, which leads to improvement in water quality. For that purpose, it is necessary to return the sludge scraper 126 to the full position as shown at the right end in FIG. 17, but in the conventional method, assuming that the tail side wheel 128 is arranged as far back as possible on the haunch 127 side. However, as shown in FIG. 16, the end of the advance / retreat switching interlocking member 122 cannot be retracted to the point where it exceeds the peripheral point a of the tail side wheel 128. Therefore, the sludge scraper 126 reaches the front b of FIG. However, I was able to retreat with sufficient margin.

そこで本実施形態では、図8ないし図13(図8・図9は前進時、図10・図11は復帰途中時、図12・図13は復帰終端時(掻寄態勢移行前))に示すように、後連動リンク89の後端に伝導条材66の端部の他に後軸周りレバー90を平行関係に分けて連結した。そうすると図12(復帰終端時)に示すように、復帰終端において進退切換下突片64に連結された後連動リンク89が後軸周りレバー90を一杯まで押して汚泥スクレーパ53をハンチ部8上まで一杯に持ってきたとしても、伝導条材66末端の方は後連動リンク89の後端(図右端)とは別の後側に少し遅れた位置に移動してなくてテール側ホイール88の周位点近くまで余裕長さcがあることになり、その結果、汚泥スクレーパ53は充分余裕をもってハンチ部8上で掻寄方向に下げスイングすることができていつもハンチ部8上の汚泥を掻き落としながら掻寄態勢に移行させることができるようになる。91はヘッド側ホイール71とテール側ホイール88間で進退移動する伝導条材66を案内する条材ガイドで、アングル状の本体とボルトおよびケミカルアンカーなどで構成してある。92は浮き上がり防止ローラーで、端取付枠30に取り付けたブラケット93を介してガイドレール7に接触し浮き上がり防止可能にしている。 Therefore, in the present embodiment, FIGS. 8 to 13 (FIGS. 8 and 9 are in the forward direction, FIGS. 10 and 11 are in the middle of the return, and FIGS. 12 and 13 are in the end of the return (before the transition to the scraping posture)). As described above, in addition to the end portion of the conductive strip 66, the rear shaft peripheral lever 90 was connected to the rear end of the rear interlocking link 89 in a parallel relationship. Then, as shown in FIG. 12 (at the end of return), the rear interlocking link 89 connected to the advance / retreat switching lower projectile 64 at the end of return pushes the lever 90 around the rear axle to the full extent to fill the sludge scraper 53 to the top of the haunch portion 8. Even if it is brought to, the end of the conductive strip 66 does not move to a position slightly behind the rear end (right end in the figure) of the rear interlocking link 89, and the peripheral position of the tail side wheel 88. There is a margin length c close to the point, and as a result, the sludge scraper 53 can swing down on the haunch portion 8 in the scraping direction with sufficient margin, always scraping off the sludge on the haunch portion 8. You will be able to shift to a sludge posture. Reference numeral 91 denotes a strip guide for guiding the conductive strip 66 that moves back and forth between the head side wheel 71 and the tail side wheel 88, and is composed of an angle-shaped main body, bolts, chemical anchors, and the like. Reference numeral 92 denotes a floating prevention roller, which comes into contact with the guide rail 7 via a bracket 93 attached to the end mounting frame 30 to prevent lifting.

一方、駆動部75側においては、図2、図18、図19に示すように池上壁76に通口95が開けられており、その通口95を通じて伝導条材66の上部が通されているが、その通口95を同じく利用して反転切換機構96の一部である伝達材97が通されている。この実施形態では、伝達材97が通るところに渡架板80があることからこの渡架板80に挿通孔80aを開けておくことでそれに通すようにしてある。伝達材97は、ワイヤロープやリンクチェーンなどでなり、駆動部カバー98で密閉化された空間内に回転自在に設けられた転換ホイール99に掛け回されている。伝達材97の一方である下端には、昇降ロッド100を介してウエイト機能をもつ応動ローラー101が設けられて受板68上に立設された長孔付きローラーガイド102に沿って上下し得る状態にしてある。このローラーガイド102は前取付台15側の取付台本体37から水平向きに突設された先端楔型をしたアクチュエータである作用部材103の進出により掻寄終端において持ち上げ作用されるようになっている。 On the other hand, on the drive unit 75 side, as shown in FIGS. 2, 18, and 19, a through port 95 is opened in the pond upper wall 76, and the upper portion of the conductive strip 66 is passed through the through port 95. However, the transmission material 97, which is a part of the reversing switching mechanism 96, is passed through the through port 95 in the same manner. In this embodiment, since there is a transfer plate 80 where the transmission material 97 passes, an insertion hole 80a is formed in the transfer plate 80 so that the transfer member 80 can pass through the transfer plate 80. The transmission material 97 is made of a wire rope, a link chain, or the like, and is hung on a conversion wheel 99 rotatably provided in a space sealed by a drive unit cover 98. A response roller 101 having a weight function is provided at one lower end of the transmission material 97 via an elevating rod 100, and can move up and down along a roller guide 102 with an elongated hole erected on a receiving plate 68. It is set to. The roller guide 102 is lifted at the scraping end by advancing the working member 103, which is a tip wedge-shaped actuator projecting horizontally from the mounting base body 37 on the front mounting base 15 side. ..

一方、伝達材97の転換ホイール99を越えた部分には、長孔付きで縦長状の昇降応動材105がウエイト機能をもって設けられ、この昇降応動材105は受板81上に突設したガイド板106に添ってガイドローラー107で軽快に昇降案内されるようになっている。109は昇降応動材105に突設したスイッチ作動子、110は反転検知スイッチ、111はスイッチ取付バーであり、111は反転補助スイッチであり、反転検知スイッチ110への作用によって駆動源83は反転応動して伝導条材66は掻寄方向Xであった牽引作用であったものが復帰方向Yへの牽引作用に切り換えられる。作用部材103が後退して応動ローラー101が下がることによりローラーガイド102は持ち上がるが駆動源83の反転状態は図示しない保持回路により維持されるものとなる。従来はスクレーパ軸の外側一端に作用部材を設けて池側壁側に対向状に設置した反転切換機構を構成してなるものであったので、反転切換が不安定な作動をするものとなっていたのに対し、本実施形態のように機体の幅間中央近くの前の誤作動しにくい位置に作用部材103を設置するとともに反転切換機構96もそれに対応した位置に設置して作動させるようにしたので、反転応動が場合によって不安定になりかつ誤作動の原因ともなっていた。尚、沈澱池下流側においても駆動源は構成されないが同様の反転切換機構が構成されるものとする。 On the other hand, in the portion of the transmission material 97 beyond the conversion wheel 99, a vertically long elevating and lowering reaction material 105 with a long hole is provided with a weight function, and the elevating and lowering reaction material 105 projects from the receiving plate 81. Along with 106, the guide roller 107 can easily guide the vehicle up and down. 109 is a switch actuator projecting from the elevating reaction member 105, 110 is a reversing detection switch, 111 is a switch mounting bar, 111 is a reversing auxiliary switch, and the drive source 83 is reversing and responding by acting on the reversing detection switch 110. Then, the conductive strip 66, which had a traction action in the scraping direction X, is switched to a traction action in the return direction Y. The roller guide 102 is lifted by retracting the working member 103 and lowering the response roller 101, but the inverted state of the drive source 83 is maintained by a holding circuit (not shown). In the past, a working member was provided at the outer end of the scraper shaft to form a reversing switching mechanism installed so as to face the side wall of the pond, so that the reversing switching was unstable. On the other hand, as in the present embodiment, the working member 103 is installed at a position near the center of the width of the machine where malfunction is unlikely to occur, and the reversing switching mechanism 96 is also installed at a position corresponding to the operating member 103 to operate. Therefore, the reversal response became unstable in some cases and caused a malfunction. It should be noted that a drive source is not configured on the downstream side of the sedimentation basin, but a similar reversal switching mechanism is configured.

図1から図7は、前後3枚の汚泥スクレーパ53…を垂直に下げた姿勢にするとともに車輪45…をガイドレール7上に機体13を前進させ前進端がピット6の手前2m前後にきた際の様子を示している。伝導条材66は駆動部75によるX方向への牽引により前伝導アンカー65を前向きに牽き、それにより進退切換連動材28を前進させて端板25に当てて前進力を与えるようにするとともに上突片59から連動リンク58と軸周りレバー57を介して汚泥スクレーパ53を垂直な掻寄状態にするようにしてある。中間の汚泥スクレーパ53も上突片59・連動リンク58・軸周りレバー57を介して同じように垂直な掻寄状態にされる。後部の汚泥スクレーパ53は、下突片64・後連動リンク89・後軸周りレバー90を介して図2のような掻寄状態とされる。3枚の汚泥スクレーパ53…の前後間隔に対し機体の進退ストロークはやや長く設定され、このような設定にしておくことで、例えば、後部の汚泥スクレーパ53の前進(掻寄)により掻き寄せられた汚泥位置は、中間の汚泥スクレーパ53が持ち上げられて復帰して掻寄状態とされた際の位置よりも少し前になるようにされるので、複数の汚泥スクレーパ53…の進退により後の汚泥が次々と前方へと掻き進めて最後には前部の汚泥スクレーパ53により汚泥ピット6内に掻き落とされるという繰り返しで全体サイクルがなっている。 1 to 7 show when the three sludge scrapers 53 ... in the front and rear are in a vertically lowered posture and the wheels 45 ... are advanced on the guide rail 7 and the forward end is about 2 m in front of the pit 6. It shows the state of. The conductive strip 66 pulls the front conductive anchor 65 forward by being pulled in the X direction by the drive unit 75, whereby the advance / retreat switching interlocking member 28 is advanced and applied to the end plate 25 to give a forward force. The sludge scraper 53 is brought into a vertical scraping state from the projecting piece 59 via the interlocking link 58 and the shaft circumference lever 57. The sludge scraper 53 in the middle is also brought into a vertical scraping state via the upper projecting piece 59, the interlocking link 58, and the shaft rotation lever 57. The sludge scraper 53 at the rear is brought into a scraping state as shown in FIG. 2 via the lower projectile piece 64, the rear interlocking link 89, and the lever 90 around the rear axle. The advance / retreat stroke of the aircraft is set to be slightly longer with respect to the front-rear distance between the three sludge scrapers 53 ... By setting such a setting, for example, the sludge scraper 53 at the rear is scraped by advancing (scratching). Since the sludge position is set to be slightly before the position when the intermediate sludge scraper 53 is lifted and returned to the state of being scraped, the sludge afterwards is moved by the advancement and retreat of the plurality of sludge scrapers 53. The whole cycle is repeated by scraping forward one after another and finally scraping into the sludge pit 6 by the sludge scraper 53 at the front.

作用部材103が前進して反転切換機構96の応動により駆動源83が反転駆動されると、伝導条材66がXとは逆のY方向に駆動され、その結果、後部の汚泥スクレーパ53は後軸周りレバー90が後方向に牽かれることで上昇し、また進退切換連動材28が後向きに牽かれて中間と前部の上突片59が後向きに牽かれることで中間および前部の汚泥スクレーパ53,53が前上がりに上昇することになるとともに前記進退切換連動材28が後部の取付台本体37前の端板25に当たることで機体13を後向きに牽き戻し復帰態勢となる。 When the working member 103 advances and the drive source 83 is reversely driven by the reaction of the reverse switching mechanism 96, the conductive strip 66 is driven in the Y direction opposite to X, and as a result, the rear sludge scraper 53 is rearward. The shaft circumference lever 90 is pulled backward to raise it, and the advance / retreat switching interlocking member 28 is pulled backward, and the middle and front upper projecting pieces 59 are pulled backward to cause sludge scrapers in the middle and front. As 53 and 53 rise forward, the advance / retreat switching interlocking member 28 hits the end plate 25 in front of the rear mounting base main body 37, so that the machine body 13 is pulled back and returned.
