Description

本発明は、塵芥収集車に関わり、特に分別された異なる種類の塵芥を積み込み可能にする塵芥収集車に関する。   The present invention relates to a garbage collection vehicle, and more particularly, to a garbage collection vehicle that enables loading of different types of separated garbage.

一般に、塵芥収集車は、例えば、図１０に概略を示すように車両の中央に塵芥収容箱１０１が設けられ、この塵芥収容箱１０１の後方に塵芥投入箱１０２が配置されている。更に、この塵芥投入箱１０２内には、投入口（図示せず）から塵芥投入箱１０２内に投入された塵芥を塵芥収容箱１０１内に積み込む塵芥積込装置１０３が設けられている。   In general, for example, as shown schematically in FIG. 10, a garbage collection vehicle is provided with a dust container box 101 at the center of the vehicle, and a dust container box 102 is disposed behind the dust container box 101. Further, a dust loading device 103 is provided in the dust throwing box 102 for loading the dust thrown into the dust throwing box 102 from the charging port (not shown) into the dust storage box 101.

この塵芥積込装置１０３は、塵芥投入箱１０２内に車幅方向に沿って設けられた回転軸１０４によって回転自在に軸支される回転板１０５と、回転軸１０４の上方で車幅方向に沿って塵芥投入箱１０２に設けられた押込板支持軸１０６に支持された押込板１０７とを有し、塵芥投入箱１０２に投入された塵芥を回転板１０５によって掻き上げ、この回転板１０５によって掻き上げられた塵芥を押込板１０７によって塵芥収容箱１０１内に押し込むように構成されている。   The dust loading device 103 includes a rotating plate 105 that is rotatably supported by a rotating shaft 104 provided in the dust throwing box 102 along the vehicle width direction, and is disposed above the rotating shaft 104 in the vehicle width direction. And a pushing plate 107 supported by a pushing plate support shaft 106 provided in the dust throwing box 102, and the dust thrown into the dust throwing box 102 is scraped up by the rotating plate 105, and is scraped up by the rotating plate 105. The formed dust is pushed into the dust container 101 by the pushing plate 107.

ところで、環境問題や資源再利用に対する関心の高まりから、例えば段ボール等の再資源化が叫ばれ、再資源材料となる資源ゴミ等の塵芥と、一般の厨雑芥とを分別して回収することが行われている。そこで、この分別された種類の異なる塵芥を効率的に回収するために、塵芥収容箱を複数の収容室に区画した、いわゆる多層型の塵芥収集車が開発されている。   By the way, due to the growing concern about environmental problems and resource reuse, for example, the recycling of cardboard and other materials is called out, and it is possible to separate and collect garbage such as resource trash, which is used as recycled material, and general garbage. Has been done. Therefore, in order to efficiently collect the sorted different types of dust, a so-called multi-layered garbage collection vehicle in which a dust storage box is partitioned into a plurality of storage chambers has been developed.

この多層型の塵芥収集車としては、例えば塵芥収容箱を左右に２分割して並列に配置された各収容室を形成し、各々の収容室の後方に各々塵芥投入室及び塵芥積込装置を配設した圧縮式左右２層型の塵芥収集車がある。   As this multi-layered garbage collection vehicle, for example, a dust storage box is divided into left and right parts to form respective storage chambers arranged in parallel, and a dust input chamber and a dust loading device are respectively provided behind each storage chamber. There is a compression-type left and right two-layer garbage truck that is installed.

また、塵芥収容箱を上下に２分割して積み重ねるように配置された上層及び下層の収容室の後方に各々塵芥投入室及び積込装置を配設した圧縮式水平２層型の塵芥収集車がある。この圧縮式水平２層型の塵芥収集車は、例えば図１１に示すように塵芥収容箱１０１内が上層収容室１０１Ａ及び下層収容室１０１Ｂに上下に区画され、上層収容室１０１Ａ及び下層収容室１０１Ｂの各後方に、各々上層用投入室１０２Ａ及び下層用投入室１０２Ｂが連設されている。   In addition, there is a compression type horizontal two-layer garbage collection vehicle in which a dust input chamber and a loading device are respectively arranged behind the upper layer and lower layer storage chambers arranged so as to divide the dust storage box into two parts. is there. As shown in FIG. 11, for example, as shown in FIG. 11, the inside of the dust storage box 101 is divided into an upper layer storage chamber 101A and a lower layer storage chamber 101B, and the upper and lower storage chambers 101A and 101B. An upper layer input chamber 102 </ b> A and a lower layer input chamber 102 </ b> B are connected to the rear of each.

上層用投入室１０２Ａ内に上層用塵芥積込装置１０３Ａが設けられている。この上層用塵芥積込装置１０３Ａは、上層用投入室１０２Ａ内に回転軸１０４Ａによって回転自在に軸支される回転板１０５Ａと、押込板支持軸１０６Ａに揺動自在に支持された押込板１０７Ａとを有し、上層用投入室１０２Ａに投入された塵芥を回転板１０５Ａによって掻き上げ、回転板１０５Ａによって掻き上げられた塵芥を押込板１０７Ａによって上層収容室１０１Ａ内に押し込むように構成されている。下層用投入室１０２Ｂ内にも同様の下層用塵芥積込装置１０３Ｂが設けられ、下層用投入室１０２Ｂに投入された塵芥を回転板１０５Ｂによって掻き上げ、回転板１０５Ｂによって掻き上げられた塵芥を押込板１０７Ｂによって下層収容室１０１Ｂ内に押し込むように構成されている。   An upper layer dust loading device 103A is provided in the upper layer charging chamber 102A. The upper layer dust loading device 103A includes a rotary plate 105A that is rotatably supported by a rotary shaft 104A in an upper layer input chamber 102A, and a push plate 107A that is swingably supported by a push plate support shaft 106A. The dust thrown into the upper layer loading chamber 102A is scraped up by the rotating plate 105A, and the dust scraped up by the rotating plate 105A is pushed into the upper layer accommodating chamber 101A by the pushing plate 107A. A similar lower layer dust loading device 103B is also provided in the lower layer input chamber 102B. The dust thrown into the lower layer input chamber 102B is scraped up by the rotating plate 105B, and the dust scraped up by the rotating plate 105B is pushed in. The plate 107B is configured to be pushed into the lower layer accommodation chamber 101B.

上記各２層型の圧縮式塵芥収集車にあっては、各々異なる塵芥に応じた各収容室が設けられ、各収容室に対応して投入室及び積込装置を備えることから、１台の塵芥収集車によって分別された２種類の異なる塵芥を同時に回収することが可能になり、回収作業の効率化が得られる。   In each of the above-mentioned two-layer type compression-type garbage collection vehicles, each storage chamber corresponding to each different dust is provided, and since there is a loading chamber and a loading device corresponding to each storage chamber, It becomes possible to simultaneously collect two different types of dust separated by the garbage truck, and the efficiency of the collection work can be obtained.

しかし、前者の圧縮式左右２層型の塵芥収集車は、塵芥収容箱が左右独立した２室構造となっているため、分別収集した塵芥の比重が左右の収容室間で異なると、車両の左右重量分布が偏在して車両姿勢が傾く等、車両の走行安定性に影響を及ぼすことが懸念される。   However, the former compression-type left and right two-layer garbage collection vehicle has a two-chamber structure in which the dust storage box is independent on the left and right, so if the specific gravity of the separately collected dust differs between the left and right storage chambers, There is a concern that the running stability of the vehicle may be affected, for example, the left-right weight distribution is unevenly distributed and the vehicle posture is inclined.

一方、後者の圧縮式水平２層型の塵芥収集車は、塵芥収容箱が上下に独立した２室構造であるため、上記左右２層型の塵芥収集車に比べて、塵芥の左右重量分布の偏在が少なく、荷重の重量バランスに優れ、走行安定性が確保される。   On the other hand, the latter compression type horizontal two-layer garbage truck has a two-chamber structure in which the dust storage boxes are vertically independent. Therefore, compared with the left and right two-layer garbage truck, There is little uneven distribution, the weight balance of the load is excellent, and running stability is ensured.

しかし、収容室を上下に積み重ねるように積層された圧縮式水平２層型の塵芥収集車にあっては、上層の収容室に対応する投入室が高所に配設されることから、作業者が地上から高所の投入室内へ塵芥を投入する必要があり、その作業には極めて大きな労力を要し、かつ作業者が地上から高所の投入室内に設けられた積込装置の作動状況を直視することは困難であり、塵芥投入のタイミングの判断に困難を来たし円滑な塵芥収集作業に影響を及ぼすことが懸念される。   However, in a compression type horizontal two-layer garbage truck that is stacked so that the storage chambers are stacked one above the other, the input chamber corresponding to the upper storage chamber is disposed at a high place. However, it is necessary to throw dust into the input chamber at a high place from the ground, and the work is extremely laborious, and the operator can check the operation status of the loading device installed in the input chamber at the high place from the ground. It is difficult to look directly, and there is a concern that it will be difficult to judge the timing of throwing in dust, and that it will affect smooth dust collection work.

従って、かかる点に鑑みなされる本発明の目的は、荷重の重量バランスに優れた圧縮式水平２層型の塵芥収集車において、特に上層の収容室への塵芥の投入作業に要する労力の軽減及び円滑な塵芥収集作業が得られる塵芥収集車を提供することにある。   Accordingly, an object of the present invention made in view of such a point is to reduce the labor required for throwing dust into the upper storage chamber, particularly in a compression type horizontal two-layer type garbage truck excellent in weight balance of load. An object of the present invention is to provide a garbage truck that can perform a smooth dust collection work.

上記目的を達成する本発明の塵芥収集車は、下層収容室と上層収容室とに区画された塵芥収容箱の後方に、上記下層収容室及び上層収容室に各々対応した下層用投入室及び上層用投入室を有する塵芥投入箱が連接して配置され、上記下層用投入室内及び上層用投入室内に各々投入された塵芥を各々対応する下層収容室内及び上層収容室内に積み込む下層用塵芥積込装置及び上層用塵芥積込装置を備えた塵芥収集車において、上記下層用塵芥積込装置は、上記下層用投入室内に回転自在に設けられて該下層用投入室内に投入された塵芥を掻き上げる下層用回転板を有し、上記上層用塵芥積込装置は、上記上層用投入室内に回転自在に設けられて該上層用投入室内に投入された塵芥を掻き上げる上層用回転板を有し、上記下層用回転板を支持する下層用回転軸及び上記上層用回転板を支持する上層用回転軸が上記下層収容室の床面と略同一高さにあることを特徴とする。   The dust collection vehicle of the present invention that achieves the above object is provided with a lower layer input chamber and an upper layer respectively corresponding to the lower layer storage chamber and the upper layer storage chamber behind the dust storage box partitioned into the lower layer storage chamber and the upper layer storage chamber. A dust loading device for lower layer, in which a dust loading box having a loading chamber is connected and disposed, and the dust loaded into the lower loading chamber and the upper loading chamber is loaded into the corresponding lower and upper storage chambers, respectively. In the garbage truck equipped with the upper layer dust loading device, the lower layer dust loading device is provided in the lower layer charging chamber so as to be rotatable so as to scrape the dust thrown into the lower layer charging chamber. The upper layer dust loading device has an upper layer rotation plate that is rotatably provided in the upper layer charging chamber and scrapes up the dust thrown into the upper layer charging chamber. Support the lower rotating plate Upper rotary shaft for supporting the rotary shaft and the upper rotating plate for the layer is equal to or in the floor surface and substantially the same height of the lower housing chamber.

本発明の塵芥収集車によると、下層収容室と上層収容室とに区画された圧縮式水平２層型の塵芥収集車において、上層収容室に対応する上層用投入室を下層用投入室と略同一高さに配置され、下層用投入室と同じ低い位置からの上層用投入室への塵芥の投入が可能になり、その投入作業が容易になり、投入作業に要する労力の大幅な軽減がもたらされると共に、下層用積込装置及び上層用積込装置等の作動状況を直視することができ、塵芥投入のタイミングの判断が容易になり円滑な塵芥収集作業が可能になる。   According to the garbage collection vehicle of the present invention, in the compression horizontal two-layer type garbage collection vehicle partitioned into the lower layer storage chamber and the upper layer storage chamber, the upper layer input chamber corresponding to the upper layer storage chamber is substantially referred to as the lower layer input chamber. It is arranged at the same height, and it becomes possible to input dust into the upper layer input chamber from the same position as the lower layer input chamber, which makes the input work easier and greatly reduces the labor required for the input operation. In addition, the operating status of the lower layer loading device, the upper layer loading device, and the like can be directly viewed, so that it is easy to determine the timing of throwing dust, and smooth dust collection work is possible.

On the other hand, the dust input box 5 is configured such that the bracket 4 is pivoted with respect to the dust storage box 3 by the expansion and contraction of the lift cylinder 8 installed between the dust storage box 3 and the dust input box 5. It is configured to tilt so as to be in contact with and away from the rear part, and the lower end of the dust input box 5 is locked to the lower rear end of the dust container 3 by a lashing device (not shown) operated by a lock cylinder. Has been.

塵芥投入箱５内は、上記塵芥収容箱３に区画形成された下層収容室１１及び上層収容室２１に対応して図３（ａ）及び（ｂ）に示すように、隔壁９によって左右に２分割されて下層用投入室１２と上層用投入室２２とが同一高さ位置に区画され、下層用投入室１２及び上層用投入室２２に開口する各投入口（図示せず）が略同一高さに設定されると共に、下層用投入室１２内及び上層用投入室２２内に各々下層用塵芥積込装置１３及び上層用塵芥積込装置２３が配設されている。   As shown in FIGS. 3 (a) and 3 (b), the inside of the dust input box 5 is divided into two left and right by the partition wall 9 corresponding to the lower layer storage chamber 11 and the upper layer storage chamber 21 defined in the dust storage box 3. The lower input chamber 12 and the upper input chamber 22 are divided at the same height, and the input ports (not shown) opened to the lower input chamber 12 and the upper input chamber 22 are substantially the same height. The lower layer dust loading device 13 and the upper layer dust loading device 23 are disposed in the lower layer loading chamber 12 and the upper layer loading chamber 22, respectively.

この塵芥収集車１は、予め分別された塵芥、例えば厨雑芥及び資源ゴミを各々別の収容箱に積み込み分別回収するものであり、例えば下層用投入室１２に厨雑芥を投入し、下層用塵芥積込装置１３によって下層収容室１１に積み込まれ、上層用投入室２２に資源ゴミが投入されて上層用塵芥積込装置２３によって、上層収容室２１に資源ゴミが積み込まれる。   This garbage collection vehicle 1 loads and collects separately separated dust, for example, garbage and resource garbage, in separate storage boxes, for example, throws garbage into the lower input chamber 12, and lowers the lower The garbage is loaded into the lower layer storage chamber 11 by the dust loading device 13, the resource garbage is thrown into the upper layer loading chamber 22, and the resource garbage is loaded into the upper layer storage chamber 21 by the upper layer dust loading device 23.

塵芥投入箱５の収集車１の進行方向に向かって塵芥投入箱５の左側に区画形成された下層用投入室１２に配設される下層用塵芥積込装置１３は、図２（ａ）に示すように、下層用投入室１２内に車幅方向に沿って配置された下層用押込板支軸１４に揺動自在に軸支される下層用押込板１５と、下層用押込板１５の下方位置で車幅方向に沿って下層用投入室１２内に配置される下層用回転軸１６に支持される下層用回転板１７とを備えている。   The lower layer dust loading device 13 disposed in the lower layer input chamber 12 defined on the left side of the dust input box 5 in the traveling direction of the collection vehicle 1 of the dust input box 5 is shown in FIG. As shown, a lower push plate 15 pivotally supported by a lower push plate support shaft 14 disposed in the lower input chamber 12 along the vehicle width direction, and below the lower push plate 15. And a lower layer rotating plate 17 supported by a lower layer rotating shaft 16 disposed in the lower layer charging chamber 12 at a position along the vehicle width direction.

下層用押込板１５は、下層用押込板１５の上端と下層用投入室１２の上端との間に架設された押込シリンダ１８の伸縮によって下層用押込板支軸１４を揺動中心に揺動前端位置と揺動後端位置との間を揺動し、下層用回転板１７は、油圧モータ（図示せず）によって下層用回転軸１６を回転駆動することによって回転する。また、下層収容室１１内に塵芥を押し込む下層用押込板１５は、図３（ａ）に示すように、その下層収容室１１内に塵芥を押し込む面に、塵芥の押し込み方向を上記下層収容室１１の中央部へ指向させる傾斜面１５ａを有している。なお、符号１９は、下層用投入室１２内に投入した塵芥が上層用投入室２２内に押し上げられるのを防ぐ仕切板である。   The lower push plate 15 has a swing front end centered on the lower push plate support shaft 14 by the expansion and contraction of the push cylinder 18 installed between the upper end of the lower push plate 15 and the upper end of the lower input chamber 12. The lower layer rotating plate 17 is rotated by rotationally driving the lower layer rotating shaft 16 by a hydraulic motor (not shown). Further, as shown in FIG. 3 (a), the lower layer pushing plate 15 that pushes dust into the lower layer storage chamber 11 has a direction in which dust is pushed into the lower layer storage chamber 11, and the lower layer storage chamber 11 11 has an inclined surface 15a directed toward the center. Reference numeral 19 denotes a partition plate that prevents the dust put into the lower layer input chamber 12 from being pushed up into the upper layer input chamber 22.

ここで、下層用塵芥積込装置１３による塵芥積み込みの作動を図４によって説明する。   Here, the operation of dust loading by the lower layer dust loading device 13 will be described with reference to FIG.

図４（ａ）に示すように、下層用回転板１７の先端が下層収容室１１の床面１１ａの後端と略一致する積込開始位置でかつ、下層用押込板１５が揺動前端位置に各々停止する状態で塵芥、例えば予め分別された厨雑芥を投入口から下層用投入室１２内に投入し、操作盤（図示せず) の作動スイッチ操作により下層用塵芥積込装置１３を作動させる。   As shown in FIG. 4 (a), the lower end rotating plate 17 is at the loading start position where the tip of the lower layer rotating plate 17 substantially coincides with the rear end of the floor surface 11a of the lower layer accommodating chamber 11, and the lower layer pushing plate 15 is at the swing front end position. In the state where each is stopped, dust, for example, pre-sorted dust, is introduced into the lower layer input chamber 12 from the input port, and the lower layer dust loading device 13 is operated by operating the operation switch of the operation panel (not shown). Operate.

この操作盤の作動スイッチ操作により油圧モータが正転して下層用回転軸１６が回転駆動され、下層用回転軸１６に設けられた下層用回転板１７が回転する。そして、図４（ｂ）に示すように、下層用回転板１７が押込板戻り開始位置に達すると、押込シリンダ１８が収縮し、揺動前端位置にある下層用押込板１５を揺動後端位置へ向けて揺動開始させる。   By operating the operation switch on the operation panel, the hydraulic motor is rotated forward to rotate the lower layer rotating shaft 16, and the lower layer rotating plate 17 provided on the lower layer rotating shaft 16 rotates. Then, as shown in FIG. 4B, when the lower layer rotating plate 17 reaches the pushing plate return start position, the pushing cylinder 18 contracts, and the lower layer pushing plate 15 at the swinging front end position is moved to the trailing end. Start swinging toward the position.

下層用回転板１７が更に回転して図４（ｃ）に示す押込板戻り完了位置に達すると、下層用押込板１５が揺動後端位置まで揺動した後、押込シリンダ１８の収縮を停止して下層用押込板１５を揺動後端位置に保持する。一方、油圧モータによる下層用回転板１７の回転は続行されて下層用投入室１２内に投入された厨雑芥を下層用回転板１７によって掻き上げ、下層用回転板１７の先端が下層収容室１１の床面１１ａの後端と略一致する積込開始位置Ｉに達すると、油圧モータが停止して下層用回転板１７が図４（ｄ）に示すように積込開始位置で停止する。   When the lower layer rotating plate 17 further rotates and reaches the pushing plate return completion position shown in FIG. 4C, the lower layer pushing plate 15 swings to the rear end position, and then the contraction of the pushing cylinder 18 is stopped. Then, the lower layer pressing plate 15 is held at the swing rear end position. On the other hand, the rotation of the lower layer rotating plate 17 by the hydraulic motor is continued, and the dust put into the lower layer charging chamber 12 is scraped up by the lower layer rotating plate 17, and the lower end rotating plate 17 has its tip at the lower layer accommodating chamber. 11 reaches the loading start position I substantially coincident with the rear end of the floor surface 11a, the hydraulic motor stops and the lower layer rotating plate 17 stops at the loading start position as shown in FIG.

更に、押込シリンダ１８に油圧が供給されて下層用押込シリンダ１８が伸長し、図４（ｅ）のように揺動後端位置に位置する下層用押込板１５を揺動前端位置まで揺動させて下層用回転板１７によって掻き上げられた厨雑芥を下層収容室１１内に押し込み、押込シリンダ１８の収縮を停止して下層用押込板１５が揺動前端位置に停止した図４（ａ）及び図５に示す１サイクル完了状態に復帰する。   Further, the hydraulic pressure is supplied to the pushing cylinder 18 so that the lower layer pushing cylinder 18 is extended, and the lower layer pushing plate 15 located at the rocking rear end position is swung to the rocking front end position as shown in FIG. 4 (a) in which the dust scraped up by the lower layer rotating plate 17 is pushed into the lower layer accommodating chamber 11, the contraction of the pushing cylinder 18 is stopped, and the lower layer pushing plate 15 is stopped at the swinging front end position. And it returns to the completion state of 1 cycle shown in FIG.

これら図４の（ａ）から（ｅ）に示す各作動を繰り返すことにより投入口から連続的に下層用投入室１２内に投入された厨雑芥を順次下層収容室１１内に押し込み収容する。この際、下層用押込板１５の傾斜面１５ａを介して厨雑芥が下層収容室１１の中央部に向けて押し出されるため、厨雑芥が下層収容室１１内で偏ることなく順次円滑に内部へと押し込まれる。   By repeating each of the operations shown in FIGS. 4 (a) to 4 (e), the dusts continuously introduced into the lower layer input chamber 12 from the input port are sequentially pushed into the lower layer storage chamber 11 and stored. At this time, the dust is pushed out toward the central portion of the lower layer storage chamber 11 through the inclined surface 15 a of the lower layer push plate 15. It is pushed into.

一方、収集車１の進行方向に向かって塵芥投入箱５の右側に区画された上層用投入室２２に配設した上層用塵芥積込装置２３は、図２（ｂ）に示すように、ブラケット４によって塵芥収容箱３の上部後端に揺動自在に軸支されて上層収容室２１の後部開口２１ａを開閉すると共に上層用押込板を兼ねる上層収容室開閉蓋２４と、上層収容室開閉蓋２４の下方位置で車幅方向に沿って上層用投入室２２内に配設される上層用押上板支軸２５に揺動自在に軸支される上層用押上板２６と、上層用押上板２６の下方位置で車幅方向に沿って上層用投入室２２内に配置される上層用回転軸２７に支持される上層用回転板２８とを備えている。なお、上層用回転板２８を支持する上層用回転軸２７は、上記した下層用回転板１７を支持する下層用回転軸１６と同軸として駆動源となる油圧モータを共用してもよい。   On the other hand, as shown in FIG. 2 (b), the upper layer dust loading device 23 disposed in the upper layer input chamber 22 partitioned on the right side of the dust input box 5 toward the traveling direction of the collection vehicle 1 is a bracket. 4 is pivotally supported by the upper rear end of the dust storage box 3 to open and close the rear opening 21a of the upper layer storage chamber 21 and also serves as an upper layer pushing plate, and an upper layer storage chamber opening / closing lid 24. The upper-layer push-up plate 26 pivotally supported by the upper-layer push-up plate support shaft 25 disposed in the upper-layer input chamber 22 along the vehicle width direction at a position below the vehicle 24, and the upper-layer push-up plate 26 And an upper layer rotating plate 28 supported by an upper layer rotating shaft 27 disposed in the upper layer charging chamber 22 along the vehicle width direction. The upper layer rotating shaft 27 that supports the upper layer rotating plate 28 may share a hydraulic motor that serves as a drive source coaxially with the lower layer rotating shaft 16 that supports the lower layer rotating plate 17 described above.

更に、塵芥収容箱３と上層収容室開閉蓋２４の間に開閉蓋用シリンダ２９が架設され、この開閉蓋用シリンダ２９の伸縮によって上層収容室開閉蓋２４がブラケット４を中心に揺動して上層収容室２１の後部開口２１ａを開閉し、かつ上層用押上板２６の中間部と上層用投入室２２の上端との間に押上板駆動部として機能する押上シリンダ３０が架設され、この押上シリンダ３０の伸縮によって、上層用押上板２６が上層用押上板支軸２５を揺動中心として揺動前端位置と揺動後端位置との間を揺動するように構成されている。また、上層収容室２１内に塵芥を押し込む上層収容室開閉蓋２４は、図３（ｂ）に示すように、その上層収容室２１内に塵芥を押し込む面に塵芥の押し込み方向を上層収容室２１の中央部へ指向させる傾斜面２４ａを有している。   Further, an opening / closing lid cylinder 29 is installed between the dust container 3 and the upper layer storage chamber opening / closing lid 24, and the upper layer storage chamber opening / closing lid 24 swings around the bracket 4 by the expansion / contraction of the opening / closing lid cylinder 29. A push-up cylinder 30 that opens and closes the rear opening 21a of the upper-layer storage chamber 21 and functions as a push-up plate driving unit is provided between an intermediate portion of the upper-layer push-up plate 26 and the upper end of the upper-layer throw-in chamber 22. The upper layer push-up plate 26 is configured to swing between the swing front end position and the swing rear end position with the upper layer push-up plate support shaft 25 as the swing center by the expansion and contraction of 30. Further, as shown in FIG. 3B, the upper layer storage chamber opening / closing lid 24 that pushes dust into the upper layer storage chamber 21 changes the direction in which dust is pushed into the surface into which the dust is pushed into the upper layer storage chamber 21. It has the inclined surface 24a to which it points to the center part.

ここで、上層用塵芥積込装置２３による塵芥積み込みの作動を図６及び図７によって説明する。   Here, the dust loading operation by the upper layer dust loading device 23 will be described with reference to FIGS.

先ず、図６（ａ）に示すように上層収容室開閉蓋２４が上層収容室２１の後部開口２１ａを閉鎖した状態において、上層用回転板２８の先端が下層収容室１１の床面１１ａの後端と略一致する積込開始位置でかつ、上層用押上板２６が揺動前端位置に各々停止する状態で予め分別された資源ゴミを投入口から上層用投入室２２内に投入し、上層用塵芥積込装置２３を作動させると、上層用回転軸２７が回転駆動されて上層用回転板２８が回転する。   First, as shown in FIG. 6A, in the state where the upper layer storage chamber opening / closing lid 24 closes the rear opening 21a of the upper layer storage chamber 21, the tip of the upper layer rotating plate 28 is located behind the floor surface 11a of the lower layer storage chamber 11. At the loading start position substantially coinciding with the end, and with the upper layer push-up plate 26 stopped at the swinging front end position, the pre-sorted resource waste is introduced into the upper layer introduction chamber 22 from the introduction port, and the upper layer When the dust loading device 23 is operated, the upper layer rotating shaft 27 is driven to rotate, and the upper layer rotating plate 28 rotates.

そして、図６（ｂ）に示すように、上層用回転板２８が上層用押上板２６の戻り開始位置に達すると、押上シリンダ３０の伸長によって揺動前端位置にある上層用押上板２６を揺動後端位置へ向けて揺動開始させる。次いで、図６（ｃ）に示すように上層用回転板２８が更に回転して上層用押上板戻り完了位置に達すると、上層用押上板２６が揺動後端位置まで揺動して、この位置に保持される。一方、図６（ｄ）に示すように、上層用回転板２８の回転は続行されて、上層用投入室２２内に投入された資源ごみを上層用回転板２８によって掻き上げ、上層用回転板２８の先端が下層収容室１１の床面１１ａのやや上方の押上開始位置に達すると、ここで停止する。   Then, as shown in FIG. 6B, when the upper layer rotating plate 28 reaches the return start position of the upper layer pushing plate 26, the upper cylinder pushing plate 26 at the rocking front end position is swung by extension of the pushing cylinder 30. Start swinging toward the rear end position. Next, as shown in FIG. 6 (c), when the upper layer rotary plate 28 further rotates and reaches the upper layer push-up plate return completion position, the upper layer push-up plate 26 swings to the rear end position. Held in position. On the other hand, as shown in FIG. 6 (d), the rotation of the upper layer rotating plate 28 is continued, and the resource waste thrown into the upper layer charging chamber 22 is scraped up by the upper layer rotating plate 28, whereby the upper layer rotating plate When the tip of 28 reaches the push-up start position slightly above the floor surface 11a of the lower layer storage chamber 11, it stops here.

更に、図７（ｅ）に示すように、揺動後端位置の上層用押上板２６を揺動前端位置まで揺動させると共に、図７（ｆ）のように、上層収容室開閉蓋２４を揺動して上層収容室２１の後部開口２１ａを開放状態とする。そして、上層用回転板２８によって掻き上げられた資源ごみを、上層用押上板２６の揺動によって、上層収容室２１の床面、即ち隔壁１０の後端付近の積込開始位置まで押し上げる。次いで、図７（ｇ）に示すように、上層収容室開閉蓋２４が揺動して上層収容室２１内に資源ごみを押し込みながら上層収容室２１の後部開口２１ａを閉鎖し、図８に示す１サイクル完了状態になる。これらの図６（ａ）から図７（ｇ）各作動を繰り返すことにより、投入口から連続的に上層用投入室２２内に投入された資源ごみを順次上層収容室２１内に押し込み収容する。この際、上層収容室開閉蓋２４の傾斜面２４ａを介して資源ごみが上層収容室２１の中央部に向けて押し出されるため、資源ごみが上層収容室２１内で偏ることなく順次内部に押し込まれる。   Further, as shown in FIG. 7E, the upper layer push-up plate 26 at the swing rear end position is swung to the swing front end position, and the upper layer storage chamber opening / closing lid 24 is moved as shown in FIG. 7F. It swings to open the rear opening 21a of the upper layer accommodation chamber 21. Then, the resource garbage scraped up by the upper layer rotating plate 28 is pushed up to the loading start position near the floor surface of the upper layer accommodating chamber 21, that is, the rear end of the partition wall 10 by the swinging of the upper layer pushing plate 26. Next, as shown in FIG. 7 (g), the upper-layer storage chamber opening / closing lid 24 swings to close the rear opening 21a of the upper-layer storage chamber 21 while pushing the resource garbage into the upper-layer storage chamber 21, as shown in FIG. One cycle is completed. By repeating these operations shown in FIGS. 6 (a) to 7 (g), the resource waste continuously introduced into the upper layer input chamber 22 from the input port is sequentially pushed into the upper layer storage chamber 21 and stored. At this time, since the resource waste is pushed out toward the central portion of the upper layer storage chamber 21 through the inclined surface 24a of the upper layer storage chamber opening / closing lid 24, the resource waste is sequentially pushed into the upper layer storage chamber 21 without being biased. .

このようにして積み込み回収された塵芥は、所定回収場所に塵芥収集車１によって搬送され、 塵芥収容箱３内から排出される。   The garbage collected and collected in this manner is transported to the predetermined collection place by the garbage collection vehicle 1 and discharged from the dust container 3.

この排出作業は、図８に示すように下層収容室１１内の塵芥を回収する回収場所において、上層収容室開閉蓋２４によって上層収容室２１の後部開口２１ａを閉鎖状態に保持すると共に、固縛装置による塵芥投入箱５の下端部の係止を解除する。   As shown in FIG. 8, the discharge operation is performed by holding the rear opening 21a of the upper layer storage chamber 21 in the closed state by the upper layer storage chamber opening / closing lid 24 in the collection place for collecting the dust in the lower layer storage chamber 11, and The lock | rock of the lower end part of the dust input box 5 by an apparatus is cancelled | released.

そして、リフトシリンダ８に油圧を供給して塵芥投入箱５を図９に示すように押し上げると共に、収容箱傾倒シリンダ７に油圧を供給して塵芥収容箱３を傾倒させて下層収容室１１内の塵芥を後部開口１１ａから排出する。   Then, the hydraulic pressure is supplied to the lift cylinder 8 to push up the dust box 5 as shown in FIG. 9, and the hydraulic pressure is supplied to the storage box tilting cylinder 7 to tilt the dust storage box 3 and Dust is discharged from the rear opening 11a.

下層収容室１１内の塵芥の排出が完了した後に、先ず収容箱傾倒シリンダ７を作動してシャシー２上に載置する位置に復帰させた後に、リフタシリンダ８を作動して塵芥投入箱５を塵芥収容箱３の後部に当接するように下げ、かつ固縛装置により塵芥投入箱５の下端部を塵芥収容箱３の下部後端に係止する。   After the discharge of the dust in the lower storage chamber 11 is completed, the storage box tilting cylinder 7 is first operated to return to the position where it is placed on the chassis 2, and then the lifter cylinder 8 is operated to set the dust input box 5. The dust container box 3 is lowered so as to contact the rear part, and the lower end part of the dust container box 5 is locked to the lower rear end of the dust container box 3 by a lashing device.

続いて、上層収容室２１内の塵芥を回収する回収場所に移動し、固縛装置による塵芥投入箱５の下端部の係止を解除する。   Then, it moves to the collection place which collects the dust in the upper layer accommodation chamber 21, and latches the latching of the lower end part of the dust input box 5 by a lashing device.

そして、リフトシリンダ８を作動して塵芥投入箱５を押し上げると共に、収容箱傾倒シリンダ７を作動して塵芥収容箱３を傾倒させ、かつ開閉蓋用シリンダ２９を作動して上層収容室開閉蓋２４を揺動して上層収容室２１の後部開口２１ａを開放して、上層収容室２１内の塵芥を排出する。   Then, the lift cylinder 8 is operated to push up the dust box 5, and the storage box tilting cylinder 7 is operated to tilt the dust storage box 3, and the opening / closing cover cylinder 29 is operated to open the upper layer storage chamber opening / closing cover 24. Is swung to open the rear opening 21a of the upper layer storage chamber 21, and the dust in the upper layer storage chamber 21 is discharged.

このように構成される塵芥収集車１によると、上層収容室２１に対応する上層用投入室２２、特にその投入口を下層用投入室１２と略同一高さに配置され、下層用投入室１２と同じ低い位置からの上層用投入室２２への塵芥の投入が可能になり、その投入作業が容易になり、投入作業に要する労力の大幅な軽減がもたらされると共に、上層用積込装置２３、特に上層用回転板２８等の作動状況を直視することができ、塵芥投入のタイミングの判断が容易になり円滑な塵芥収集作業が可能になる。   According to the garbage collection vehicle 1 configured as described above, the upper layer input chamber 22 corresponding to the upper layer storage chamber 21, in particular, the input port thereof is disposed at substantially the same height as the lower layer input chamber 12, and the lower layer input chamber 12 is disposed. It becomes possible to throw dust into the upper layer loading chamber 22 from the same low position as the above, and the loading work becomes easy, the labor required for the loading work is greatly reduced, and the upper layer loading device 23, In particular, it is possible to look directly at the operating state of the upper layer rotary plate 28, etc., making it easy to determine the timing of throwing in the dust, and enabling a smooth dust collection operation.

また、下層用塵芥積込装置１３が、下層用回転板１７及び下層用回転板１７によって掻き上げられた塵芥を下層用押込板１５によって下層収容室１１に押し込む従来の塵芥積込装置によって構成され、かつ上層用塵芥積込装置２３が、上層用投入室２２内に投入された塵芥を上層用回転板２８によって掻き上げ、この上層用回転板２８によって掻き上げられた塵芥を上層用押上板２６によって押し上げ、押上板２６によって押し上げられた塵芥を上層収容室開閉蓋２４によって上層収容室２１内に押し込むように構成することから、比較的簡単な構成で下層用塵芥積込装置１３及び上層用塵芥積込装置２３が有効的に形成できる。   The lower layer dust loading device 13 is configured by a conventional dust loading device that pushes the dust scraped up by the lower layer rotation plate 17 and the lower layer rotation plate 17 into the lower layer accommodation chamber 11 by the lower layer push plate 15. The upper layer dust loading device 23 scrapes the dust thrown into the upper layer loading chamber 22 by the upper layer rotating plate 28, and the upper layer pushing plate 26 removes the dust scraped up by the upper layer rotating plate 28. Since the dust pushed up by the push-up plate 26 is pushed into the upper-layer storage chamber 21 by the upper-layer storage chamber opening / closing lid 24, the lower-layer dust loading device 13 and the upper-layer dust can be formed with a relatively simple configuration. The loading device 23 can be formed effectively.

更に、下層用押込板１５が塵芥の押し込み方向を下層収容室１１の中央部へ指向させる傾斜面１５ａを有し、かつ上層収容室開閉蓋２４が塵芥の押し込み方向を上層収容室２１の中央部へ指向させる傾斜面２４ａを有することから、下層収容室１１内に下層用押込板１５によって塵芥が下層収容室の中央部に指向されて押し込まれ、下層収容室１１内での塵芥の偏在が回避できて均等な積み込みが実現されると共に、上層収容室２１内に上層収容室開閉蓋２４によって塵芥が上層収容室２１の中央部に指向されて押し込まれ、上層収容室２１内での塵芥の偏在が回避できて積み込まれた塵芥の荷重による重量バランスの均衡が向上して走行安定性が確保される。   Furthermore, the lower layer pushing plate 15 has an inclined surface 15a that directs the dust pushing direction toward the center of the lower layer storage chamber 11, and the upper layer storage chamber opening / closing lid 24 directs the dust pushing direction to the center of the upper layer holding chamber 21. Since the inclined surface 24a is directed toward the bottom, the dust is pushed into the lower layer accommodating chamber 11 by the lower layer pushing plate 15 so as to be directed toward the center of the lower layer accommodating chamber, and the uneven distribution of the dust in the lower layer accommodating chamber 11 is avoided. Evenly loading is achieved, and dust is pushed into the upper layer storage chamber 21 by the upper layer storage chamber opening / closing lid 24 so as to be directed toward the center of the upper layer storage chamber 21, so that the dust is unevenly distributed in the upper layer storage chamber 21. Can be avoided and the balance of the weight balance due to the load of the loaded dust is improved, and traveling stability is ensured.

For example, in the above embodiment, the lower layer pushing plate, the upper layer pushing plate, the upper layer accommodating chamber opening / closing lid are driven by the expansion and contraction of the cylinder, and the lower layer rotating plate and the upper layer rotating plate are each driven by a hydraulic motor. As described above, it can be driven by other driving means, and the lower layer dust loading device and the upper layer loading device can also use other forms as appropriate.
