One end of a vertical air chamber front plate 19 is welded to the inner plate 17 at a position substantially corresponding to the front end 18 a of the outer plate 18. The air chamber front plate 19 is formed in a rear bent plate portion 20 bent rearward at a position recessed by a predetermined amount from the outer plate 18 in the vehicle width direction, and then bent outward again to be formed in the outer plate connecting plate portion 21. The outer plate connecting plate portion 21 is welded to the outer plate 18. The outer plate connecting plate portion 21 is inclined forward from a substantially middle position in the vertical direction. The upper end of the air chamber front plate 19 is connected to the top plate 12, and the bottom plate 22 is welded to the lower end of the air chamber front plate 19 between the inner and outer plates 18 and 19. An air outlet 24 is formed between the inner and outer plates 17 and 18 between the rear edge of the bottom plate 22 and the wind direction member 23 provided at the lower end of the rear plate 16. The inner space of the suction hood 11 formed by the top plate 12, the air chamber front plate 19, the inner and outer plates 17 and 18, and the rear plate 16 is divided into an upper air chamber 25 and a lower dust collection space 26 by the bottom plate 22.

内側板17の下端にはゴム製の側フラップ29とダートシュー30、外側板18の下端にはダートシュー31、底板22の前端にはゴム製の前フラップ32、後側板16の下端にはゴム製の後側フラップ33、天板12の前方傾斜部14の下方屈曲部14aにはゴム製の前側フラップ34が夫々取り付けられている。このことから、路面Rに接地した吸引フード11の内側空間は略密閉状態となるので、ブロア5の駆動によりホッパ7内の空気が、吐出ダクト6a、吸引フード11の内側空間、吸引ダクト8、ホッパ7と循環する循環空気流となり、その空気流による気流搬送によって路面R上の塵埃がホッパ7に回収されることになる。また、ホッパ7内の空気がブロア5に吸い込まれることでホッパ7を介して吸引ダクト8には吸引気流が作用するようになっている。   A rubber side flap 29 and a dirt shoe 30 are provided at the lower end of the inner plate 17, a dirt shoe 31 is provided at the lower end of the outer plate 18, a rubber front flap 32 is provided at the front end of the bottom plate 22, and a rubber is provided at the lower end of the rear plate 16. A rubber front flap 34 is attached to the rear flap 33 made of the product and the downward bent portion 14a of the front inclined portion 14 of the top plate 12, respectively. Therefore, the inner space of the suction hood 11 grounded to the road surface R is in a substantially sealed state, so that the air in the hopper 7 is driven by the blower 5 so that the discharge duct 6a, the inner space of the suction hood 11, the suction duct 8, A circulated air flow that circulates with the hopper 7, and dust on the road surface R is collected by the hopper 7 by airflow conveyance by the air flow. Further, the air in the hopper 7 is sucked into the blower 5 so that a suction airflow acts on the suction duct 8 through the hopper 7.

前記外側板18は、空気室前板19の外側板接続板部21との接合位置まで、空気室前板19の上下長さより少し狭い上下幅で前端18aから切り欠かれており、側ブラシ53が、空気室前板19の前方にある側ブラシ収容空間35に格納された時に、側ブラシ支持機構50の揺動ブラケット51と平行リンク52との干渉を避ける逃げ空間が形成されている。外側板接続板部21からは外側に向けてブラケット36が固着してある。ブラケット36の先端は外側板18よりも側方に突出している。側ブラシ支持機構50の揺動ブラケット51が前記ブラケット36に垂直軸回りに揺動するように支持されている。揺動ブラケット51には、駆動モータMにより回転する側ブラシ53を備えた取付ブラケット54が上下の平行リンク52により昇降可能に支持されている。揺動ブラケット51と下側の平行リンク52との間には側ブラシ53を持ち上げる方向に荷重を付与するスプリング55が介装されている。下側の平行リンク52と吐出ダクト8の下側部分との間には、側ブラシ53の張り出し量を定めるチェン56が連結されている。   The outer plate 18 is cut out from the front end 18a with a vertical width slightly narrower than the vertical length of the air chamber front plate 19 up to the joining position of the air chamber front plate 19 with the outer plate connecting plate portion 21, and the side brush 53 However, when it is stored in the side brush housing space 35 in front of the air chamber front plate 19, a clearance space is formed to avoid interference between the swing bracket 51 of the side brush support mechanism 50 and the parallel link 52. A bracket 36 is fixed outwardly from the outer plate connecting plate portion 21. The tip of the bracket 36 protrudes laterally from the outer plate 18. A swing bracket 51 of the side brush support mechanism 50 is supported by the bracket 36 so as to swing around a vertical axis. A mounting bracket 54 having a side brush 53 that is rotated by a drive motor M is supported on the swing bracket 51 so as to be movable up and down by upper and lower parallel links 52. A spring 55 is provided between the swing bracket 51 and the lower parallel link 52 to apply a load in the direction of lifting the side brush 53. Between the lower parallel link 52 and the lower portion of the discharge duct 8, a chain 56 that determines the amount of protrusion of the side brush 53 is connected.

吸引フード11の内、外側板17,18は、図3,5に示すように、空気室25と対応する部分の上端部が天板12より上方に突出した突出部60に形成されている。内側板17と外側板18の突出部60は横枠61で接続されている。この横枠61と車体4下部に設けたブラケット62との間は、夫々横枠61とブラケット62との接続部をボールジョイントとした一対の支持リンクからなる平行リンク63で接続されている。こうして、吸引フード11は、車体4に対して上下と張り出し方向内外に移動可能に支持されている。   As shown in FIGS. 3 and 5, the outer plates 17 and 18 of the suction hood 11 are formed in a protruding portion 60 whose upper end portion corresponding to the air chamber 25 protrudes upward from the top plate 12. The protrusions 60 of the inner plate 17 and the outer plate 18 are connected by a horizontal frame 61. The horizontal frame 61 and the bracket 62 provided at the lower part of the vehicle body 4 are connected by a parallel link 63 including a pair of support links in which a connection portion between the horizontal frame 61 and the bracket 62 is a ball joint. Thus, the suction hood 11 is supported so as to be movable up and down and in and out of the vehicle body 4.

次に側ブラシ53の昇降張出装置70を説明する。前記天板12の前方傾斜部14の上側に、側ブラシリフトシリンダ(駆動源)71が取り付けてある。側ブラシリフトシリンダ71のピストンロッド72先端には動滑車73が回転自在に設けてある。天板12上には、プーリブラケット74が固着してあり、プーリブラケット74には水平軸線回りに回転自在なガイドプーリ75と車幅方向内方に向けて傾斜した軸線回りに回転自在な傾斜プーリ76とが設けてある。天板12の下方において、一端を前記取付ブラケット54に連結された引っ張り索(ワイヤ)77は、天板12に設けた貫通孔78を通って天板12上方に引き出され、傾斜プーリ76、ガイドプーリ75、動滑車73を経て、その他端がプーリブラケット74に連結されている。側ブラシリフトシリンダ71のピストンロッド72を後退端まで引き込むと、ワイヤ77を介して側ブラシ53は吸引フード11の側ブラシ収容空間35に収容される収容位置P1に位置する。一方、ピストンロッド72を前進端まで突出すると、前記ワイヤ77は弛むので、吸引フード11が後述の格納位置S1に持ち上げられている時には側ブラシ53は接地するまで下方に下降し、清掃作業時に吸引フード11が接地しているときには、側ブラシ53が回転されることで前記チェン56により制限される張り出し位置P2まで側ブラシ53が吸引フード11の側方に張り出すことになる。   Next, the raising / lowering extension apparatus 70 of the side brush 53 is demonstrated. A side brush lift cylinder (drive source) 71 is attached to the upper side of the front inclined portion 14 of the top plate 12. A moving pulley 73 is rotatably provided at the tip of the piston rod 72 of the side brush lift cylinder 71. A pulley bracket 74 is fixed on the top plate 12. The pulley bracket 74 has a guide pulley 75 rotatable around a horizontal axis and an inclined pulley rotatable around an axis inclined inward in the vehicle width direction. 76 is provided. Below the top plate 12, a pulling cord (wire) 77, one end of which is connected to the mounting bracket 54, is pulled out above the top plate 12 through a through hole 78 provided in the top plate 12, and an inclined pulley 76, a guide The other end is connected to the pulley bracket 74 via the pulley 75 and the moving pulley 73. When the piston rod 72 of the side brush lift cylinder 71 is retracted to the retracted end, the side brush 53 is located at the accommodation position P <b> 1 accommodated in the side brush accommodation space 35 of the suction hood 11 via the wire 77. On the other hand, when the piston rod 72 protrudes to the forward end, the wire 77 is loosened. Therefore, when the suction hood 11 is lifted to the storage position S1, which will be described later, the side brush 53 descends downward until it contacts the ground, and suction is performed during the cleaning operation. When the hood 11 is grounded, the side brush 53 projects to the side of the suction hood 11 to the projecting position P2 limited by the chain 56 by rotating the side brush 53.

天板12の前方傾斜部14の車幅方向外側には、側ブラシ53の前方に位置する揺動カバー80の基端部が垂直軸線回りに回動するように枢着してある。この揺動カバー80は、弾性部材81によって側方外側に開くように付勢されている。また、揺動カバー80は、図3,4に示すように、張り出し位置P2にある側ブラシ53の前方に立ち塞がるように形成され、揺動カバー80の下部にはゴム製の揺動フラップ82が取り付けられている。揺動カバー80と取付ブラケット54とはワイヤ等の連結部材83で連結されており、側ブラシ53が収容位置P1に向けて移動すると、連結部材83により揺動カバー80が引っ張られて側ブラシ収容空間35に接近して略吸引フード11の側面に沿う状態となり、また、その状態から側ブラシ53が張り出し方向に移動すると、揺動カバー80は弾性部材81のばね力で外方に揺動する。前記連結部材83の長さは、側ブラシ53が張り出し位置P2にある時、揺動カバー80が吸引フード11の側面に対して直交する位置となるように設定されている。   On the outer side in the vehicle width direction of the front inclined portion 14 of the top plate 12, a base end portion of the swing cover 80 positioned in front of the side brush 53 is pivotally attached so as to rotate about the vertical axis. The swing cover 80 is urged so as to open laterally outward by an elastic member 81. 3 and 4, the swing cover 80 is formed so as to stand in front of the side brush 53 at the overhanging position P <b> 2, and a rubber swing flap 82 is formed below the swing cover 80. Is attached. The swing cover 80 and the mounting bracket 54 are connected by a connecting member 83 such as a wire. When the side brush 53 moves toward the storage position P1, the swing cover 80 is pulled by the connecting member 83 and the side brush is stored. When the side brush 53 moves in the projecting direction from the state close to the space 35 and substantially along the side surface of the suction hood 11, the swing cover 80 swings outward by the spring force of the elastic member 81. . The length of the connecting member 83 is set so that the swing cover 80 is perpendicular to the side surface of the suction hood 11 when the side brush 53 is in the overhanging position P2.

吸引フード11は、天板12の前後に昇降チェン84が連結され、その昇降チェン84を、車体4側に設けたフードリフトシリンダ85に接続している。また、吸引フード11の内側板17には、車体4から垂下されたブラケット86に一端を上下方向に揺動するように軸支した張り出しシリンダ87のピストンロッド88先端が水平軸回りに回動自在に連結されている。フードリフトシリンダ85により昇降チェン84を引き上げて吸引フード11を路面Rから離間し、かつ、フード張り出しシリンダ87のピストンロッド88先端を後退端まで引き込むと、吸引フード11は車体4の内方となる格納位置S1に格納される。また、フードリフトシリンダ85により昇降チェン84を緩め、図5のように、フード張り出しシリンダ87のピストンロッド88先端を前進端に突出させると、吸引フード11が車体4の側方に張り出して接地する接地位置S2に位置する。   In the suction hood 11, a lifting chain 84 is connected to the front and rear of the top plate 12, and the lifting chain 84 is connected to a hood lift cylinder 85 provided on the vehicle body 4 side. Further, on the inner plate 17 of the suction hood 11, the tip of the piston rod 88 of the overhanging cylinder 87 that is pivotally supported on a bracket 86 suspended from the vehicle body 4 so as to swing up and down is rotatable about a horizontal axis. It is connected to. When the lift hood 84 is pulled up by the hood lift cylinder 85 to separate the suction hood 11 from the road surface R and the front end of the piston rod 88 of the hood overhanging cylinder 87 is pulled to the retracted end, the suction hood 11 is inward of the vehicle body 4. Stored in storage position S1. Further, when the elevating chain 84 is loosened by the hood lift cylinder 85 and the tip of the piston rod 88 of the hood overhanging cylinder 87 protrudes to the forward end as shown in FIG. 5, the suction hood 11 overhangs to the side of the vehicle body 4 and is grounded. Located at the ground contact position S2.

次に、中央ごみ収集装置100について説明する。中央ごみ収集装置100は、左,右側板101,102の間に、屈曲前板103と後方部分をコ字状に屈曲した上板104とが溶着されたものである。前記屈曲前板103と上板104の長手方向(車幅方向)長さは、上記左右のごみ収集装置10の吸引フード11が車体4の側方に張り出した状態で左右の吸引フード11と重なり合う長さである。上板104の下方には左,右側板101,102間にわたって仕切板105が溶着されている。また、仕切板105の後端縁と上板104の後方下端に設けた風向部材106との間には、左,右側板101,102間にわたって空気噴出口107が形成されている。屈曲前板103にはゴム製の前フラップ108、風向部材106にはゴム製の後フラップ109、左,右側板101,102の下端にはダートシュー110,111が夫々取り付けられている。上板104、左,右側板101,102、前フラップ108、後フラップ109により形成される中央ごみ収集装置100の内側空間は、仕切板105によって上側の空気室112と下側の塵埃回収空間113に仕切られている。   Next, the central waste collection device 100 will be described. The central waste collection device 100 is formed by welding a front plate 103 and a top plate 104 whose rear portions are bent in a U shape between left and right plates 101 and 102. The longitudinal direction (vehicle width direction) length of the front bending plate 103 and the upper plate 104 overlaps with the left and right suction hoods 11 in a state where the suction hoods 11 of the left and right garbage collection devices 10 protrude to the side of the vehicle body 4. Length. A partition plate 105 is welded between the left and right plates 101 and 102 below the upper plate 104. An air jet 107 is formed between the left and right plates 101 and 102 between the rear edge of the partition plate 105 and the wind direction member 106 provided at the rear lower end of the upper plate 104. A rubber front flap 108 is attached to the bent front plate 103, a rubber rear flap 109 is attached to the wind direction member 106, and dirt shoes 110, 111 are attached to the lower ends of the left and right plates 101, 102, respectively. The inner space of the central waste collection device 100 formed by the upper plate 104, the left and right plates 101 and 102, the front flap 108, and the rear flap 109 is divided into an upper air chamber 112 and a lower dust collection space 113 by the partition plate 105. It is divided into.

上板104に設けた貫通孔には、吐出ダクト6の他端側6cが空気室112に連通するように連結されている。仕切板105に設けた貫通孔114には、吸引ダクト8の他端が上板104を貫通して塵埃回収空間113に連通するように連結されている。また、吸引ダクト8には、ホッパ7と塵埃回収空間113の連通を開閉する開閉手段40が備えられている。このことから、路面Rに接地した中央ごみ収集装置100の内側空間は略密閉状態となるので、ブロア5の駆動によりホッパ7内の空気が、吐出ダクト6c、中央ごみ収集装置100の内側空間、吸引ダクト8、ホッパ7と循環する循環空気流となり、その空気流による気流搬送によって路面R上の塵埃がホッパ7に回収されることになる。また、ホッパ7内の空気がブロア5に吸い込まれることで、ホッパ7を介して吸引ダクト8には吸引気流が作用するようになっている。尚、中央ごみ収集装置100は図示しない昇降装置により、路面Rから離れた格納位置S1aと路面Rに接した接地位置S2aとの間で昇降するようになっている。   The other end side 6 c of the discharge duct 6 is connected to the through hole provided in the upper plate 104 so as to communicate with the air chamber 112. The other end of the suction duct 8 is connected to the through hole 114 provided in the partition plate 105 so as to pass through the upper plate 104 and communicate with the dust collection space 113. The suction duct 8 is provided with an opening / closing means 40 for opening / closing communication between the hopper 7 and the dust collection space 113. From this, the inner space of the central garbage collector 100 grounded to the road surface R is substantially sealed, so that the air in the hopper 7 is driven by the blower 5 so that the discharge duct 6c, the inner space of the central garbage collector 100, A circulating air flow circulates between the suction duct 8 and the hopper 7, and dust on the road surface R is collected by the hopper 7 by airflow conveyance by the air flow. Further, the air in the hopper 7 is sucked into the blower 5, so that a suction airflow acts on the suction duct 8 through the hopper 7. The central waste collection device 100 is moved up and down between a storage position S1a away from the road surface R and a grounding position S2a in contact with the road surface R by an elevator device (not shown).

各吸引ダクト8に備えた開閉手段40について説明する。各開閉手段40は全て同じ構造であるので、左側のごみ収集装置10に備えた開閉手段40について説明する。開閉手段40は貫通孔41a,42aを備えた第1連結部材41と第2連結部材42とから成るダクト連結機構43と、ホッパ7とごみ収集装置10の連通を遮断する遮蔽板44とから成る。吸引ダクト8はホッパ側ダクト8aとごみ収集装置側ダクト8bとに分割されており、第1連結部材41はホッパ側ダクト8a端面に固着され、第2連結部材42はごみ収集装置側ダクト8b端面に固着されている。第1連結部材41の端部は第2連結部材42の端部に設けた軸部材45に回動自在に支持されている。第1連結部材41の上面にはトグルクランプ46が設置され、下面には弾性部材から成る押付部材47が固着されている。押付部材47には、前記貫通孔41aと同径の貫通孔47aが設けてある。第2連結部材42の上面にはフック部材48が設置されている。よって、第1連結部材41の押付部材47を第2連結部材42の上面に当接させた後、クランプ46の引掛け部材46aをフック部材48に引掛け、クランプ46のレバー46bを回動すると、第1連結部材41が第2連結部材42に引き寄せられ、押付部材47が第2連結部材42の上面に押し付けられることで第1連結部材41と第2連結部材42が連結したことになる。この状態では、第1,2連結部材41,42に備えた貫通孔41a,42aを介してホッパ側ダクト8aとごみ収集装置側ダクト8bは連通している。
また、図7,8に示すように、第2連結部材42の上面に遮蔽板44を載置する。遮蔽板44は第2連結部材42に設けたガイド部材49によって位置決めされている。この状態で、上記のように第1連結部材41と第2連結部材42とをクランプ46によって連結すると、ごみ収集装置側ダクト8bが遮蔽板44により塞がれるので、ホッパ7とごみ収集装置10の連通が遮断されることになる。尚、ホッパ7とごみ収集装置10との連通を遮断しない場合には、遮蔽板44は車体4に設けた図示しないフック部材に引掛けてある。
The opening / closing means 40 provided in each suction duct 8 will be described. Since all the opening / closing means 40 have the same structure, the opening / closing means 40 provided in the left-side dust collection device 10 will be described. The opening / closing means 40 includes a duct connecting mechanism 43 including a first connecting member 41 and a second connecting member 42 having through holes 41 a and 42 a, and a shielding plate 44 that blocks communication between the hopper 7 and the dust collecting device 10. . The suction duct 8 is divided into a hopper side duct 8a and a dust collector side duct 8b, the first connecting member 41 is fixed to the end surface of the hopper side duct 8a, and the second connecting member 42 is an end surface of the dust collector side duct 8b. It is fixed to. The end of the first connecting member 41 is rotatably supported by a shaft member 45 provided at the end of the second connecting member 42. A toggle clamp 46 is installed on the upper surface of the first connecting member 41, and a pressing member 47 made of an elastic member is fixed to the lower surface. The pressing member 47 is provided with a through hole 47a having the same diameter as the through hole 41a. A hook member 48 is installed on the upper surface of the second connecting member 42. Therefore, after the pressing member 47 of the first connecting member 41 is brought into contact with the upper surface of the second connecting member 42, the hooking member 46a of the clamp 46 is hooked on the hook member 48, and the lever 46b of the clamp 46 is rotated. The first connecting member 41 is attracted to the second connecting member 42, and the pressing member 47 is pressed against the upper surface of the second connecting member 42, whereby the first connecting member 41 and the second connecting member 42 are connected. In this state, the hopper side duct 8a and the dust collection device side duct 8b communicate with each other through the through holes 41a, 42a provided in the first and second connecting members 41, 42.
Further, as shown in FIGS. 7 and 8, a shielding plate 44 is placed on the upper surface of the second connecting member 42. The shielding plate 44 is positioned by a guide member 49 provided on the second connecting member 42. In this state, when the first connecting member 41 and the second connecting member 42 are connected by the clamp 46 as described above, the dust collecting device side duct 8b is blocked by the shielding plate 44, so the hopper 7 and the dust collecting device 10 are closed. Will be cut off. When the communication between the hopper 7 and the dust collecting device 10 is not blocked, the shielding plate 44 is hooked on a hook member (not shown) provided on the vehicle body 4.

上記構成の路面清掃車1における路面清掃について説明する。路面Rの路肩側のみを清掃する場合には、図9に示すように、予め遮蔽板44を用いてホッパ7と右側のごみ収集装置10、ホッパ7と中央ごみ収集装置100との連通を遮断すると共に、吐出ダクト6に備えた切換手段9によりブロア5の空気吐出側5aと右側のごみ収集装置10、中央ごみ収集装置100の連通を遮断する。
路面清掃車1が清掃場所に移動すると、フードシリンダ85により昇降チェン84を緩めると共にフード張り出しシリンダ87のピストンロッド88先端を前進端に突出させると、格納位置S1にある左側の吸引フード11は、車体4の側方に張り出して路面Rに接地する接地位置S2に位置する。略同時に、側ブラシリフトシリンダ71のピストンロッド72を前進端まで突出してワイヤ77を緩めて側ブラシ53を接地状態とする。次いで側ブラシ53を回転すると、その回転による路面Rからの回転反力で側ブラシ53は張り出し位置P2まで吸引フード11の側方に張り出す。側ブラシ53が側方に張り出すと、揺動カバー80は弾性部材81のばね力で側ブラシ53の前方に移動する。その後、側ブラシ53の回転により路肩部分の塵埃が車体4内方に掃き寄せられる。その塵埃はブロア5の駆動によりホッパ7内の空気が吐出ダクト6a、吸引フード11の内側空間、吸引ダクト8、ホッパ7と循環する空気流によってホッパ7に回収される。また、清掃途中において、路肩部分に障害物Tがあると、図12(a)〜(b)に示すように、障害物Tに押されて揺動カバー80は後方に揺動して逃げ、同様に、側ブラシ53も障害物Tにより吸引フード11側面に向けて揺動して逃げるようになっている。
The road surface cleaning in the road cleaning vehicle 1 having the above configuration will be described. When only the road shoulder side of the road surface R is cleaned, as shown in FIG. 9, the communication between the hopper 7 and the right side dust collecting device 10, and the hopper 7 and the central waste collecting device 100 is blocked using a shielding plate 44 in advance. At the same time, the switching means 9 provided in the discharge duct 6 blocks communication between the air discharge side 5a of the blower 5 and the right-side dust collection device 10 and the central waste collection device 100.
When the road surface cleaning vehicle 1 moves to the cleaning place, the suction hood 11 on the left side in the storage position S1 is moved by loosening the lifting chain 84 by the hood cylinder 85 and projecting the tip of the piston rod 88 of the hood overhanging cylinder 87 to the forward end. It is located at a ground contact position S2 that projects to the side of the vehicle body 4 and contacts the road surface R. At substantially the same time, the piston rod 72 of the side brush lift cylinder 71 protrudes to the forward end and the wire 77 is loosened to bring the side brush 53 into a grounded state. Next, when the side brush 53 is rotated, the side brush 53 projects to the side of the suction hood 11 to the projecting position P2 by the rotational reaction force from the road surface R due to the rotation. When the side brush 53 protrudes to the side, the swing cover 80 moves to the front of the side brush 53 by the spring force of the elastic member 81. Thereafter, the dust at the road shoulder is swept into the vehicle body 4 by the rotation of the side brush 53. The dust is collected in the hopper 7 by the air flow circulating in the discharge duct 6 a, the inner space of the suction hood 11, the suction duct 8, and the hopper 7 by driving the blower 5. Further, when there is an obstacle T on the shoulder portion during the cleaning, as shown in FIGS. 12A to 12B, the swing cover 80 is pushed backward by the obstacle T and swings backward to escape. Similarly, the side brush 53 swings toward the side surface of the suction hood 11 by the obstacle T and escapes.

次に、車幅全体の清掃をする場合には、図10に示すように、予め遮蔽板44を用いてホッパ7と右側のごみ収集装置10との連通を閉鎖すると共に、吐出ダクト6に備えた切換手段9によりブロア5の空気吐出側5aと右側のごみ収集装置10の連通を遮断する。
路面清掃車1が清掃場所に移動すると、フードシリンダ85により昇降チェン84を緩めると共にフード張り出しシリンダ87のピストンロッド88先端を前進端に突出させると、格納位置S1にある左側の吸引フード11は、車体4の側方に張り出して路面Rに接地する接地位置S2に位置する。略同時に、側ブラシリフトシリンダ71のピストンロッド72を前進端まで突出してワイヤ77を緩めて側ブラシ53を接地状態とする。更に、中央ごみ収集装置100を昇降装置により格納位置S1aから接地位置S2aに移動させる。次いで側ブラシ53を回転すると、その回転による路面Rからの回転反力で側ブラシ53は張り出し位置P2まで吸引フード11の側方に張り出す。側ブラシ53が側方に張り出すと、揺動カバー80は弾性部材81のばね力で側ブラシ53の前方に移動する。その後、側ブラシ53の回転により路肩部分の塵埃が車体4内方に掃き寄せられる。その塵埃はブロア5の駆動によりホッパ7内の空気が吐出ダクト6a、吸引フード11の内側空間、吸引ダクト8、ホッパ7と循環する空気流によってホッパ7に回収される。また、左右のごみ収集装置10の間(車体4の下側)にある路面R上の塵埃は、ブロア5の駆動によりホッパ7内の空気が吐出ダクト6c、中央ごみ収集装置100、吸引ダクト8、ホッパ7と循環する空気流によってホッパ7に回収される。
Next, when the entire vehicle width is to be cleaned, as shown in FIG. 10, the communication between the hopper 7 and the dust collecting device 10 on the right side is closed in advance using a shielding plate 44 and the discharge duct 6 is provided. The switching means 9 shuts off the communication between the air discharge side 5a of the blower 5 and the dust collecting device 10 on the right side.
When the road surface cleaning vehicle 1 moves to the cleaning place, the suction hood 11 on the left side in the storage position S1 is moved by loosening the lifting chain 84 by the hood cylinder 85 and projecting the tip of the piston rod 88 of the hood overhanging cylinder 87 to the forward end. It is located at a ground contact position S2 that projects to the side of the vehicle body 4 and contacts the road surface R. At substantially the same time, the piston rod 72 of the side brush lift cylinder 71 protrudes to the forward end and the wire 77 is loosened to bring the side brush 53 into a grounded state. Further, the central waste collection device 100 is moved from the storage position S1a to the grounding position S2a by the lifting device. Next, when the side brush 53 is rotated, the side brush 53 projects to the side of the suction hood 11 to the projecting position P2 by the rotational reaction force from the road surface R due to the rotation. When the side brush 53 protrudes to the side, the swing cover 80 moves to the front of the side brush 53 by the spring force of the elastic member 81. Thereafter, the dust at the road shoulder is swept into the vehicle body 4 by the rotation of the side brush 53. The dust is collected in the hopper 7 by the air flow circulating in the discharge duct 6 a, the inner space of the suction hood 11, the suction duct 8, and the hopper 7 by driving the blower 5. In addition, dust on the road surface R between the left and right dust collection devices 10 (below the vehicle body 4) causes the air in the hopper 7 to be discharged into the discharge duct 6c, the central dust collection device 100, and the suction duct 8 by driving the blower 5. The hopper 7 is recovered by the air flow circulating with the hopper 7.

更に中央分離帯側を清掃する場合には、図11に示すように、予め遮蔽板44を用いてホッパ7と左側のごみ収集装置10、ホッパ7と中央ごみ収集装置100との連通を遮断すると共に、吐出ダクト6に備えた切換手段9によりブロア5の空気吐出側5aと左側のごみ収集装置10、中央ごみ収集装置100の連通を遮断する。
路面清掃車1が清掃場所に移動すると、上記路肩側の清掃時と同様に右側のごみ収集装置10を介して中央分離帯側にある塵埃がホッパ7に回収される。以上のことから、路面清掃車1に左右のごみ収集装置10と中央ごみ収集装置100を備え、これらを単独で、または組み合わせて路面Rに接地させることで、路肩側清掃、中央分離帯側清掃、車幅全体の清掃と、路面清掃部位を自由に設定できる。また、路面Rに接地したごみ収集装置10,100のみに循環空気流を作用させることで、路肩側のみ、中央分離帯側のみ等を清掃する際には確実に塵埃を回収することができる。更に、中央ごみ収集装置100を車体4の側方に張り出した状態の左右のごみ収集装置10に重なり合うように配置したので、路肩(中央分離帯)側の清掃時に、車体4の下側にある路面Rの清掃も行なえるから、一度に広い幅の路面清掃ができる。加えて、左右のごみ収集装置10に備えた側ブラシ53がごみ収集装置10の側方に張り出すようにしたことで、非常に広い幅の路面清掃ができる。
Further, when cleaning the side of the central separator, as shown in FIG. 11, the communication between the hopper 7 and the left side garbage collector 10 and the hopper 7 and the central garbage collector 100 is blocked using a shielding plate 44 in advance. At the same time, the switching means 9 provided in the discharge duct 6 blocks communication between the air discharge side 5a of the blower 5 and the left-side dust collection device 10 and the central waste collection device 100.
When the road surface cleaning vehicle 1 moves to the cleaning place, the dust on the central separator side is collected in the hopper 7 through the right-side dust collecting device 10 as in the case of the road shoulder side cleaning. From the above, the road cleaning vehicle 1 is provided with the left and right garbage collection devices 10 and the central garbage collection device 100, and these are grounded on the road surface R alone or in combination, thereby cleaning the road shoulder and cleaning the median strip side. The entire vehicle width and the road surface cleaning part can be set freely. Further, by allowing the circulating air flow to act only on the dust collectors 10 and 100 that are grounded to the road surface R, dust can be reliably collected when cleaning only the road shoulder side, only the central separation belt side, and the like. Further, since the central waste collection device 100 is arranged so as to overlap the left and right waste collection devices 10 in a state of projecting to the side of the vehicle body 4, the central waste collection device 100 is located below the vehicle body 4 when cleaning the road shoulder (central separation band) side. Since the road surface R can also be cleaned, a wide width road surface can be cleaned at a time. In addition, since the side brushes 53 provided on the left and right garbage collection devices 10 project to the side of the garbage collection device 10, road surfaces with a very wide width can be cleaned.
