塵芥収集装置及びそれを備えた塵芥収集車Waste collection device and waste collection vehicle equipped with the same

　本発明は、塵芥投入箱の投入口から投入された塵芥を圧縮して塵芥収容箱へ押し込む塵芥積込機構を備えた塵芥収集装置及びそれを備えた塵芥収集車に関するものである。 The present invention relates to a dust collecting device including a dust loading mechanism that compresses dust thrown from a dust inlet into a dust container and pushes it into a dust container, and a dust collecting vehicle equipped with the dust collecting device.

　従来より、塵芥収容箱の後方開口部に連接された塵芥投入箱と、この塵芥投入箱の前側に設けられた仕切板と、塵芥投入箱に設けられ、塵芥投入箱の投入口から投入された塵芥を圧縮して仕切板下方から塵芥収容箱へ押し込む塵芥積込機構とを備えた塵芥収集車は知られている。 Conventionally, the dust input box connected to the rear opening of the dust storage box, the partition plate provided on the front side of the dust input box, and the dust input box, which is input from the input of the dust input box. 2. Description of the Related Art There is a known dust collection vehicle including a dust loading mechanism that compresses dust and pushes it into the dust container from below the partition plate.

　例えば、特許文献１では、塵芥収容箱の後方開口部に連接した塵芥投入箱と、この投入箱の側壁に軸着された回転体（押込板）と、回転体を回転駆動装置によって回転運動させる第１の動力伝達機構と、回転体の軸着部と偏心した位置で回転可能に回転体に立設支持される押込板と、回転体と同方向かつ回転体の回転数の１／２の回転数となるように押込板を回転体に対して相対的に回転運動させる第２の動力伝達機構とを備え、押込板を公転自転運動させる塵芥収集車が知られている。この塵芥収集車では、塵芥投入箱の前側上部に固設された仕切板（固定プレート）の下部に噛み込み防止手段を設けている。 For example, in Patent Document 1, a dust input box connected to a rear opening of a dust storage box, a rotating body (pushing plate) pivotally attached to a side wall of the input box, and the rotating body are rotated by a rotary drive device. A first power transmission mechanism, a pushing plate that is erected and supported on the rotating body so as to be able to rotate at a position eccentric with respect to the shaft-attached portion of the rotating body, the same direction as the rotating body, and half the number of rotations of the rotating body There is known a garbage collection vehicle that includes a second power transmission mechanism that rotates a push plate relative to a rotating body so as to have a rotational speed, and that rotates and rotates the push plate. In this garbage collection vehicle, the biting prevention means is provided at the lower part of the partition plate (fixed plate) fixed to the front upper part of the dust input box.

　しかしながら、上記特許文献１の塵芥収集車では、噛み込み防止手段として、仕切板の下部に噛み込み防止用のローラ及びローラ駆動専用のモータを設ける例が開示されているが、このような構成では専用のモータを設ける分、故障の可能性や製造費用が増加するという問題がある。また、特許文献１では、他の噛み込み防止手段として、押込板の表面に常時接する遮蔽板及びそれを付勢するスプリングを設ける例が開示されている。この例では、押込板の表面は、滑らかな曲面に形成されている。また、遮蔽板はスプリングの付勢力によってその先端縁が押込板に接触している。このような構成の場合、例えばビニールシートのような、シート状で水分が付着した塵芥が押込板に張り付くと、押込板の表面（特に押込板の先端縁）と遮蔽板先端縁との間に塵芥が引っかかり、そのまま塵芥が押込板に引きずられて遮蔽板を通過してしまうという問題がある。 However, in the garbage collection vehicle of Patent Document 1, an example in which a biting prevention roller and a motor dedicated to driving the roller are provided as a biting prevention unit at the lower part of the partition plate is disclosed. As a dedicated motor is provided, there is a problem that the possibility of failure and the manufacturing cost increase. Patent Document 1 discloses an example in which a shielding plate that is always in contact with the surface of the pushing plate and a spring that biases it are provided as other biting prevention means. In this example, the surface of the pushing plate is formed into a smooth curved surface. Further, the tip edge of the shielding plate is in contact with the pushing plate by the biasing force of the spring. In the case of such a configuration, for example, when a sheet-like dust adhering to moisture sticks to the pressing plate, such as a vinyl sheet, the surface of the pressing plate (especially the leading edge of the pressing plate) and the leading edge of the shielding plate There is a problem that the dust is caught and the dust is dragged to the pushing plate as it is and passes through the shielding plate.

　本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、簡単な構成で、塵芥の逆流及び噛み込みを防止しながら塵芥を効率よく塵芥収容箱へ押し込むようにすることにある。 The present invention has been made in view of such points, and an object of the present invention is to push the dust efficiently into the dust storage box while preventing the dust from flowing back and biting with a simple configuration. It is in.

　上記の目的を達成するために、この発明では、押込板を、公転速度と自転速度が２：１となるように回転可能に支持させ、押込板の厚さ方向に対向する各表面に複数の突条を設けた。 In order to achieve the above object, according to the present invention, the pressing plate is rotatably supported so that the revolution speed and the rotation speed are 2: 1, and a plurality of surfaces are opposed to each other in the thickness direction of the pressing plate. A ridge was provided.

　具体的には、第１の発明では、塵芥収容箱の開口部に連接した塵芥投入箱と、該塵芥投入箱の該開口部と対向する側に設けられた仕切板と、該塵芥投入箱に設けられ、該塵芥投入箱の投入口から投入された塵芥を圧縮して上記仕切板下方から上記開口部側へ押し込む塵芥積込機構とを備えた塵芥収集装置を対象とする。 Specifically, in the first aspect of the present invention, a dust input box connected to the opening of the dust storage box, a partition plate provided on the side of the dust input box facing the opening, and the dust input box The present invention is directed to a dust collecting device that is provided with a dust loading mechanism that is provided and compresses dust thrown from the throwing port of the dust throwing box and pushes the dust into the opening side from below the partition plate.

　そして、上記塵芥積込機構は、
　　上記塵芥投入箱の一対の対向側壁にそれぞれ回転可能に支持された一対の回転支持部材と、
　　上記一対の回転支持部材間に延びると共に該回転支持部材の回転中心と偏心して設けた回転軸を中心に回転可能に支持され、上記回転支持部材が１回転する間に同方向に１／２回転する押込板とを備え、
　上記押込板における厚さ方向に対向する一対の表面には、それぞれ上記回転軸の軸心方向に間隔をあけて複数の突条が配置され、
　上記仕切板の下端部には、各突条が通過する切欠部が形成されている。 And the dust loading mechanism is
A pair of rotation support members rotatably supported on a pair of opposing side walls of the dust box,
The rotation support member extends between the pair of rotation support members and is supported so as to be rotatable about a rotation shaft provided eccentrically with respect to the rotation center of the rotation support member. And a pushing plate that
On the pair of surfaces facing the thickness direction in the push plate, a plurality of protrusions are arranged at intervals in the axial direction of the rotating shaft, respectively.
At the lower end of the partition plate, a notch through which each protrusion passes is formed.

　上記の構成によると、回転支持部材が１回転する間に押込板が同方向に１／２回転し、塵芥投入箱の投入口から投入された塵芥が仕切板の下方を通って塵芥収容箱に押し込まれる。続けて、回転支持部材が１回転する間に押込板が同方向に１／２回転し、押込板の反対側の面で塵芥投入箱の投入口から投入された塵芥が仕切板の下方を通って塵芥収容箱に押し込まれる。このように押込板が連続的に回転して塵芥の押込作業を行うので、いわゆるプレス式塵芥収集装置や回転板式塵芥収集装置のような、圧縮、押込等各工程に切り換わるときの切換音が発生しない。そして、突条を押込板の各表面から突出させることで、押込板が回転する際に生じる仕切板の下端と押込板との隙間を押込板の表面が埋める一方、一度塵芥収容箱側へ押し込まれた塵芥は、突条に押されて押込板の表面から浮いた状態にできる。また、突条は、仕切板の切欠部内を移動するので、突条を大きくしても押込板の回転を阻害しない。従って、押込板の表面に塵芥が張り付くことを防いで塵芥の塵芥投入空間部への逆流や噛み込みを防止することができる。また、シート状で水分が付着した塵芥の場合であっても、隣り合う突条間にシート状の塵芥が吊り下げられ、その吊り下げ部分の噛み込みと塵芥投入空間部側への移動とを、仕切板の隣り合う切欠部間の壁面によって効果的に規制することができる。即ち、仕切板をスクレーパとして有効利用できる。 According to the above configuration, the pushing plate rotates in half in the same direction while the rotation support member makes one rotation, and the dust thrown in from the throwing-in port of the dust throwing box passes through the lower part of the partition plate to the dust containing box. Pushed in. Subsequently, while the rotation support member makes one rotation, the pushing plate makes a half turn in the same direction, and the dust thrown in from the throwing-in port of the dust throwing box on the opposite side of the pushing plate passes under the partition plate. And pushed into the dust bin. In this way, the pushing plate rotates continuously to perform dust pushing work, so that the switching sound when switching to each process such as compression, pushing, etc., as in the so-called press type dust collecting device and rotating plate type dust collecting device is generated. Does not occur. And by projecting the ridge from each surface of the push plate, the surface of the push plate fills the gap between the lower end of the partition plate and the push plate that is generated when the push plate rotates, and once pushed into the dust box The dust which has been pushed can be brought into a state where it is pushed by the protrusions and floats from the surface of the pushing plate. Further, since the ridge moves in the notch portion of the partition plate, even if the ridge is enlarged, the rotation of the pushing plate is not hindered. Therefore, it is possible to prevent dust from sticking to the surface of the pushing plate and prevent the dust from flowing back into and getting into the dust input space. In addition, even in the case of a sheet-like dust adhering to moisture, the sheet-like dust is suspended between adjacent ridges, and the suspended portion is bitten and moved toward the dust input space. It can be effectively regulated by the wall surface between the adjacent notches of the partition plate. That is, the partition plate can be effectively used as a scraper.

　また、従来のように噛み込み防止手段に専用のモータを設けることなく、簡単な構成で、塵芥の逆流及び噛み込みを防止することができる。 Also, it is possible to prevent dust from flowing back and biting with a simple configuration without providing a dedicated motor as a biting prevention means as in the prior art.

　第２の発明では、第１の発明において、
　上記突条は、上記回転軸の軸心方向と直交する方向に延びるように形成されており、軸心方向から見て押込板の表面からの高さが緩やかに変化する外周縁を有する。 In the second invention, in the first invention,
The ridge is formed so as to extend in a direction orthogonal to the axial direction of the rotating shaft, and has an outer peripheral edge whose height from the surface of the pushing plate gradually changes when viewed from the axial direction.

　上記の構成によると、押込板が回転しても突条は押込板の回転軸の軸心方向に移動することがない。これにより、切欠部を軸心方向に移動させるための機構を設ける必要がないので、仕切板の切欠部周辺の構造の簡素化を図ることができる。なお、「緩やかに変化する外周縁」とは、屈折部や不連続部がない外周縁、又は、屈折部を有しているがその屈折部が鈍角に形成された外周縁であることを意味する。 According to the above configuration, even if the pushing plate rotates, the protrusion does not move in the axial direction of the rotating shaft of the pushing plate. Thereby, since it is not necessary to provide a mechanism for moving the cutout portion in the axial direction, the structure around the cutout portion of the partition plate can be simplified. The “peripheral edge that changes gently” means an outer peripheral edge that does not have a refracting part or a discontinuous part, or an outer peripheral edge that has a refracting part but is formed at an obtuse angle. To do.

　また、突条が押込板の表面からの高さが緩やかに変化する外周縁を有することにより、押込板の回転に伴い、仕切板の切欠部を通過する突条の通過領域を連続的に変化させることができる。従って、突条が、仕切板の塵芥収容箱側に張り付いた塵芥を仕切板に対して上下に移動させることができる。これにより、切欠部において突条の非通過部分が存在してもその部分に塵芥が入り込むことを抑制して塵芥の噛み込みを防止することができる。 In addition, since the protrusion has an outer peripheral edge whose height from the surface of the pushing plate changes gently, the passage area of the protruding piece passing through the notch portion of the partition plate is continuously changed as the pushing plate rotates. Can be made. Therefore, the ridges can move the dust attached to the dust storage box side of the partition plate up and down with respect to the partition plate. Thereby, even if there is a non-passing portion of the protrusion at the notch, it is possible to prevent dust from entering the portion and prevent the dust from being caught.

　第３の発明では、第１又は第２の発明において、
　上記押込板の一対の先端縁を結ぶ方向から見た上記複数の突条の上記回転軸の軸心からの最大高さは、該回転軸の軸心方向中央の該突条で最も高く、中央から離れるにつれて低くなっている。 In the third invention, in the first or second invention,
The maximum height of the plurality of protrusions from the axial center of the rotating shaft viewed from the direction connecting the pair of tip edges of the pushing plate is the highest at the protrusion in the center in the axial direction of the rotating shaft. It gets lower as you move away from.

　上記の構成によると、回転軸の軸心方向中央に偏って塵芥投入空間部底方に投入された塵芥が突条によって両側壁側へ掻き分けられ、塵芥収容箱に均等に押し込まれる。このため、複数の突条に高さの変化をもたせない場合と比較して、塵芥収容箱に積載できる塵芥の量を増やすことができる。 According to the above configuration, the dust thrown to the bottom of the dust throwing space portion while being biased toward the center of the axis of the rotating shaft is scraped to the both side walls by the ridges and is pushed evenly into the dust containing box. For this reason, compared with the case where a height change is not given to a some protrusion, the quantity of the dust which can be loaded in a dust storage box can be increased.

　第４の発明では、第１又は第２の発明において、
　上記押込板の一対の先端縁を結ぶ方向から見た上記複数の突条の上記回転軸の軸心からの最大高さは、該回転軸の軸心方向中央の該突条で最も低く、中央から離れるにつれて高くなっている。 In the fourth invention, in the first or second invention,
The maximum height from the axial center of the rotating shaft of the plurality of protrusions viewed from the direction connecting the pair of tip edges of the pushing plate is the lowest at the protrusion in the axial center of the rotating shaft, It gets higher as you move away from.

　上記の構成によると、側壁側に偏って塵芥投入空間部底方に投入された塵芥が突条によって回転軸の軸心方向中央に掻き集められ、どちらかの側壁側に偏らず、塵芥収容箱に均等に押し込まれる。このため、複数の突条に高さの変化をもたせない場合と比較して、塵芥収容箱に積載できる塵芥の量を増やすことができる。 According to the above configuration, the dust thrown to the bottom of the dust throwing space portion is biased to the side of the side wall and is scraped to the center in the axial direction of the rotating shaft by the ridges, and is not biased to either side of the side wall, but to the dust containing box. It is pushed evenly. For this reason, compared with the case where a height change is not given to a some protrusion, the quantity of the dust which can be loaded in a dust storage box can be increased.

　第５の発明では、第１又は第２の発明において、
　上記押込板の一対の先端縁を結ぶ方向から見た上記複数の突条の上記回転軸の軸心からの最大高さは、該回転軸の軸心方向中央の該突条で最も低く、中央から離れるにつれて一端高くなり、再び低くなっている。 In the fifth invention, in the first or second invention,
The maximum height from the axial center of the rotating shaft of the plurality of protrusions viewed from the direction connecting the pair of tip edges of the pushing plate is the lowest at the protrusion in the axial center of the rotating shaft, As it gets away from it, it gets higher and lower again.

　上記の構成によると、塵芥投入空間部底方に投入された塵芥が突条によって両側壁側及び回転軸の軸心方向の中央に掻き分けられ、塵芥収容箱に均等に押し込まれる。このため、複数の突条に高さの変化をもたせない場合と比較して、塵芥収容箱に積載できる塵芥の量を増やすことができる。 According to the above configuration, the dust thrown into the bottom of the dust throwing space is scraped by the ridges to the both side walls and the center in the axial direction of the rotary shaft, and evenly pushed into the dust container box. For this reason, compared with the case where a height change is not given to a some protrusion, the quantity of the dust which can be loaded in a dust storage box can be increased.

　第６の発明では、第１又は第２の発明において、
　上記押込板の一対の先端縁を結ぶ方向から見て、上記押込板の一方の表面に設けた上記複数の突条の上記回転軸の軸心からの最大高さは、該回転軸の軸心方向中央の該突条で最も高く、中央から離れるにつれて低くなり、
　上記押込板の一対の先端縁を結ぶ方向から見て、上記押込板の他方の表面に設けた上記複数の突条の上記回転軸の軸心からの最大高さは、該回転軸の軸心方向中央の該突条で最も低く、中央から離れるにつれて高くなっている。 In a sixth invention, in the first or second invention,
The maximum height of the plurality of protrusions provided on one surface of the push plate from the axis of the rotary shaft, as viewed from the direction connecting the pair of tip edges of the push plate, is the axis of the rotary shaft. It is the highest at the ridge in the center in the direction, and becomes lower as it goes away from the center.
The maximum height of the plurality of protrusions provided on the other surface of the push plate from the axis of the rotary shaft when viewed from the direction connecting the pair of leading edges of the push plate is the axis of the rotary shaft. It is the lowest at the ridge at the center in the direction, and becomes higher as the distance from the center increases.

　上記の構成によると、塵芥投入空間部底方に投入された塵芥は、押込板が回転するごとに交互に一方の面の突条によって両側壁側へ掻き分けられ、他方の面の突条によって回転軸の軸心方向の中央側へ掻き集められ、塵芥収容箱に均等に押し込まれる。このため、複数の突条に高さの変化をもたせない場合と比較して、塵芥収容箱に積載できる塵芥の量を増やすことができる。 According to the above configuration, the dust thrown into the bottom of the dust throwing space is scraped to both side walls alternately by the ridges on one surface each time the push plate rotates, and rotated by the ridges on the other surface. It is scraped to the center side in the axial direction of the shaft and pushed evenly into the dust container. For this reason, compared with the case where a height change is not given to a some protrusion, the quantity of the dust which can be loaded in a dust storage box can be increased.

　第７の発明では、第１又は第２の発明において、
　上記押込板の一対の先端縁を結ぶ方向から見て、上記押込板の一方の表面に設けた上記複数の突条の上記回転軸の軸心からの最大高さは、該回転軸の軸心方向一端側の該突条で最も高く、他端側へ向かうにつれて低くなり、
　上記押込板の一対の先端縁を結ぶ方向から見て、上記押込板の他方の表面に設けた上記複数の突条の上記回転軸の軸心からの最大高さは、該回転軸の軸心方向他端側の該突条で最も高く、上記一端側へ向かうにつれて低くなっている。 In the seventh invention, in the first or second invention,
The maximum height of the plurality of protrusions provided on one surface of the push plate from the axis of the rotary shaft, as viewed from the direction connecting the pair of tip edges of the push plate, is the axis of the rotary shaft. It is the highest at the ridge on one end of the direction, and becomes lower toward the other end.
The maximum height of the plurality of protrusions provided on the other surface of the push plate from the axis of the rotary shaft when viewed from the direction connecting the pair of leading edges of the push plate is the axis of the rotary shaft. It is the highest at the protrusion on the other end side in the direction, and becomes lower toward the one end side.

　上記の構成によると、塵芥投入空間部底方に投入された塵芥は、押込板が回転するごとに一方の面の突条によって一方の側壁側へ掻き集められ、他方の面の突条によって他方の側壁側へ掻き集められ適度に振り分けられるので、塵芥収容箱に均等に押し込まれる。このため、複数の突条に高さの変化をもたせない場合と比較して、塵芥収容箱に積載できる塵芥の量を増やすことができる。 According to the above configuration, the dust thrown into the bottom of the dust throwing space portion is scraped to one side wall by the protrusion on one surface each time the pushing plate rotates, and the other protrusion by the protrusion on the other surface. Since it is scraped to the side wall and properly distributed, it is pushed evenly into the dust bin. For this reason, compared with the case where a height change is not given to a some protrusion, the quantity of the dust which can be loaded in a dust storage box can be increased.

　第８の発明では、第１又は第２の発明において、
　上記複数の突条は、上記回転軸の軸心方向から見て、上記押込板の厚さ方向に対向する一対の表面における、一方の表面の長手方向一端側と他方の表面の長手方向他端側とに該押込板の先端縁が塵芥投入空間部の底部を形成する壁面に沿って移動するときに上記投入口側となるようにそれぞれ形成され、かつ、該各突条は、上記各表面の上記長手方向中央から上記一端側又は上記他端側へ向かうにつれて該各表面から離れるように傾斜する傾斜面を有する。 In the eighth invention, in the first or second invention,
The plurality of protrusions are one end in the longitudinal direction of one surface and the other in the longitudinal direction of the other surface in a pair of surfaces opposed to the thickness direction of the pressing plate when viewed from the axial direction of the rotating shaft. And the leading edge of the pushing plate is formed so as to be on the charging port side when moving along the wall surface forming the bottom of the dust charging space portion, and each protrusion is formed on each surface. And an inclined surface that is inclined so as to be separated from each surface as it goes from the center in the longitudinal direction toward the one end side or the other end side.

　上記の構成によると、押込板の先端縁が塵芥投入空間部の底部を形成する壁面に沿って移動するときに突条が投入口側となるように配置されているので、押込板における下方に位置する表面と、その上方に位置する突条の傾斜面との間で塵芥が圧縮されながら塵芥が効率的に仕切板の下方を通って塵芥収容箱へ押し込まれるようにできる。 According to the above configuration, the protrusion is arranged on the inlet side when the leading edge of the pushing plate moves along the wall surface forming the bottom of the dust throwing space portion. While the dust is compressed between the surface located and the inclined surface of the ridge located above the dust, the dust can be efficiently pushed into the dust container box under the partition plate.

　第９の発明では、第１乃至第８のいずれか１つの発明において、
　上記仕切板には、上記各突条が上記各切欠部を通過するのに伴って開閉すると共に該各切欠部における該各突条の非通過部分を塞ぐシャッター部材が設けられている。 In a ninth invention, in any one of the first to eighth inventions,
The partition plate is provided with a shutter member that opens and closes as the ridges pass through the notches, and closes non-passing portions of the ridges at the notches.

　上記の構成によると、突条が切欠部を通過するときに突条の通過部分のみシャッター部材を開き、突条の通過後にシャッター部材が閉じるので、切欠部から塵芥が逆流したり切欠部に塵芥が噛み込んだりすることはない。 According to the above configuration, when the ridge passes through the notch, the shutter member is opened only at the passage portion of the ridge, and the shutter member is closed after passing the ridge, so that dust flows backward from the notch or the dust enters the notch. Will not bite.

　第１０の発明では、第９の発明において、
　上記シャッター部材は、付勢部材によって上記仕切板に沿って該仕切板の下端に向けて付勢されている。 In a tenth aspect, in the ninth aspect,
The shutter member is urged by the urging member toward the lower end of the partition plate along the partition plate.

　上記の構成によると、突条が切欠部を通過するときに付勢部材の付勢力に抗してシャッター部材を持ち上げ、通過後に付勢部材によってシャッター部材が押されて切欠部が閉じられる。これにより、切欠部に対する突条の動きとシャッター部材の動きとを確実に連動させることができ、切欠部における突条の非通過部分を確実に塞ぐことができる。その結果、切欠部への塵芥の噛み込みをより防ぐことができる。 According to the above configuration, when the ridge passes through the notch, the shutter member is lifted against the urging force of the urging member, and after passing, the shutter member is pushed by the urging member to close the notch. Thereby, the movement of the ridge with respect to the notch can be reliably interlocked with the movement of the shutter member, and the non-passing portion of the ridge in the notch can be reliably closed. As a result, it is possible to further prevent the dust from being caught in the notch.

　第１１の発明の塵芥収集車は、第１乃至第１０のいずれか１つの発明の塵芥収集装置を車台上に備える構成とする。 The refuse collection vehicle of the eleventh aspect of the invention is configured to include the dust collection device of any one of the first to tenth aspects of the invention on a chassis.

　上記の構成によると、日本で一般的なプレス式塵芥収集車や回転板式塵芥収集車と比較した場合、アクチュエータの数を減らすと共に圧縮，押込等各工程に切り換わるときの切換音の発生や各行程の制御をなくすことによって軽量化、構造の簡素化及び低騒音化を図りつつ、さらに、塵芥の逆流や噛み込みを防止してトラブルの少ない塵芥収集車が得られる。 According to the above configuration, when compared with press-type garbage trucks and rotating-plate-type garbage trucks that are common in Japan, the number of actuators is reduced and switching sounds are generated when switching to each process such as compression and pushing. By eliminating the stroke control, weight reduction, simplification of the structure, and noise reduction can be achieved, and further, a dust collection vehicle with less trouble can be obtained by preventing backflow and biting of the dust.

　以上説明したように、本発明によれば、一対の回転支持部材間に、この回転支持部材の回転中心に対して偏心して延びる回転軸を中心に押込板を回転可能に支持し、回転支持部材が１回転する間に押込板を同方向に１／２回転させ、押込板における厚さ方向に対向する一対の表面にそれぞれ回転軸の軸心方向に間隔をあけて複数の突条を配置し、仕切板の下端部に各突条が通過する切欠部を形成したことにより、簡単な構成で、塵芥の逆流及び噛み込みを防止しながら塵芥を効率よく塵芥収容箱へ押し込むことができる。 As described above, according to the present invention, the push plate is supported between the pair of rotation support members so as to be rotatable about the rotation axis extending eccentrically with respect to the rotation center of the rotation support member. The push plate is rotated 1/2 turn in the same direction during one rotation, and a plurality of protrusions are arranged on the pair of surfaces facing the thickness direction of the push plate at intervals in the axial direction of the rotation shaft. By forming the cutout portion through which each protrusion passes at the lower end of the partition plate, the dust can be efficiently pushed into the dust container box while preventing the dust from flowing back and biting with a simple configuration.

　以下、本発明の実施形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

　　－塵芥収集車の構造－
　図２は本発明の実施形態にかかる塵芥収集装置を備えた塵芥収集車１を示し、この塵芥収集車１の車台２上に塵芥収容箱３が搭載されている。車台２の前側には、運転室２ａが設けられている。塵芥収容箱３の後方開口部４には、その上方で投入箱支持ピン５により軸支された塵芥投入箱６が設けられている。詳しくは図示しないが、この塵芥投入箱６は、塵芥収容箱３と塵芥投入箱６との間に設けられた油圧シリンダ（電動シリンダでもよい）である回動シリンダ９（図３等に示す）により、投入箱支持ピン５を中心に回動自在に構成されている。塵芥収容箱３は、車台２に設けた傾動シリンダ１２（図６にのみ示す）を伸縮させることにより、車台２後側の傾動軸を中心に傾動可能（ダンプ可能）に構成されている。 -Structure of garbage truck-
FIG. 2 shows a refuse collection vehicle 1 provided with a dust collection device according to an embodiment of the present invention. A dust storage box 3 is mounted on a chassis 2 of the dust collection vehicle 1. A driver's cab 2 a is provided on the front side of the chassis 2. The rear opening 4 of the dust container 3 is provided with a dust input box 6 that is pivotally supported by an input box support pin 5 above it. Although not shown in detail, the dust input box 6 is a rotating cylinder 9 (shown in FIG. 3 and the like) that is a hydraulic cylinder (or an electric cylinder) provided between the dust storage box 3 and the dust input box 6. Thus, it is configured to be rotatable around the input box support pin 5. The dust container 3 is configured to be tiltable (can be dumped) around a tilting shaft on the rear side of the chassis 2 by extending and contracting a tilting cylinder 12 (shown only in FIG. 6) provided on the chassis 2.

　図１に示すように、塵芥投入箱６の後部には投入口７が開口され、その内部には塵芥積込機構２０が装備されている。塵芥積込機構２０は、塵芥投入箱６内に投入口７を通じて投入された塵芥５５を圧縮して塵芥収容箱３内に積み込むためのものである。 As shown in FIG. 1, a throwing port 7 is opened at the rear of the dust throwing box 6, and a dust loading mechanism 20 is provided in the inside. The dust loading mechanism 20 is for compressing and loading the dust 55 put into the dust throwing box 6 through the loading port 7 into the dust containing box 3.

　塵芥投入箱６における後方開口部４と対向する側には、仕切板２１が上方から延びるように設けられている。この仕切板２１は、塵芥投入箱６内の塵芥投入空間部６ｄと塵芥収容箱３の内部とを仕切るものであり、例えば、塵芥収容箱３の後方開口部４の約上半分を覆う連接部２１ａと、この連接部２１ａに連続し、下方に向かって後方へ傾斜する下端部２１ｂとを備えている。塵芥５５は、この仕切板２１の下端部２１ｂの下端２１ｃよりも下方から塵芥積込機構２０によって圧縮されて後方開口部４側へ押し込まれるようになっている。 A partition plate 21 is provided on the side facing the rear opening 4 in the dust box 6 so as to extend from above. The partition plate 21 partitions the dust input space 6d in the dust input box 6 and the inside of the dust container 3 and, for example, a connecting portion that covers the upper half of the rear opening 4 of the dust container 3. 21a and a lower end portion 21b which is continuous with the connecting portion 21a and is inclined rearwardly downward. The dust 55 is compressed by the dust loading mechanism 20 from below and below the lower end 21c of the lower end 21b of the partition plate 21 and is pushed into the rear opening 4 side.

　そして、図３～図５に示すように、塵芥積込機構２０は、塵芥投入箱６の一対の対向側壁６ａにそれぞれ回転可能に支持された、円形の一対の回転支持部材２２を備えている。この回転支持部材２２を回転させる方法としては種々の構成が考えられるが、例えば本実施形態では、油圧モータよりなる駆動モータ１４を塵芥投入箱６の左右一方の側壁６ａの内側に取り付け、この駆動モータ１４の出力軸１４ａに設けた駆動スプロケット３１と、回転支持部材２２の側壁６ａ外側（左右外側）の外側面に設けた回転支持部材側スプロケット３２との間に減速機構２４を設けている。これにより、駆動モータ１４が所定の減速割合で回転支持部材２２を回転するように構成されている。 As shown in FIGS. 3 to 5, the dust loading mechanism 20 includes a pair of circular rotation support members 22 that are rotatably supported by the pair of opposed side walls 6a of the dust throwing box 6 respectively. . Although various configurations are conceivable as a method of rotating the rotation support member 22, for example, in this embodiment, a drive motor 14 made of a hydraulic motor is attached to the inside of the left and right side walls 6a of the dust box 6, and this drive is performed. A speed reduction mechanism 24 is provided between the drive sprocket 31 provided on the output shaft 14 a of the motor 14 and the rotation support member side sprocket 32 provided on the outer surface of the side wall 6 a of the rotation support member 22. Accordingly, the drive motor 14 is configured to rotate the rotation support member 22 at a predetermined deceleration rate.

　円形の回転支持部材２２の円周面には、小径部２２１と大径部２２２からなる段付部２２３が形成されている。また、回転支持部材２２の外側面には、その回転中心に孔部２２４が設けられている。この回転支持部材２２の孔部２２４には、回転支持部材側スプロケット３２に設けた中央孔３２ａを通じて中心軸２２ａが嵌め込まれ、回転支持部材２２は、中心軸２２ａに回転可能に支持される。 A stepped portion 223 including a small diameter portion 221 and a large diameter portion 222 is formed on the circumferential surface of the circular rotation support member 22. In addition, a hole 224 is provided at the center of rotation on the outer surface of the rotation support member 22. A center shaft 22a is fitted into the hole 224 of the rotation support member 22 through a center hole 32a provided in the rotation support member side sprocket 32, and the rotation support member 22 is rotatably supported by the center shaft 22a.

　中心軸２２ａの左右外側には、円板状の鍔部２２ｂが一体に形成され、この鍔部２２ｂには、例えば４つのネジ穴２２ｃが形成されている。左右の側壁６ａには、中心軸２２ａと同心に回転支持部材２２の外径よりも若干大きい内径を有する貫通孔６ｂがそれぞれ形成され、この貫通孔６ｂ内に回転支持部材２２の段付部２２３の小径部２２１が収容されている。側壁６ａにおける貫通孔６ｂの周辺には、側面視でＴ字状の固定ブラケット２３（図４では二点鎖線で示す）が固定され、この固定ブラケット２３のボルト穴２２ｄにボルト２２ｅを挿通してネジ穴２２ｃに締結することで、中心軸２２ａが側壁６ａに対して固定されている。これにより、回転支持部材２２は、段付部２２３の小径部２２１が貫通孔６ｂ内で回転可能となるように、側壁６ａに直接支持される。また、回転支持部材２２は、側壁６ａに、固定ブラケット２３及び中心軸２２ａを介して間接支持されている。また、回転支持部材２２は、段付部２２３の大径部２２２と中心軸２２ａによって左右方向への移動が規制されている。 Disc-shaped flange portions 22b are integrally formed on the left and right outer sides of the central shaft 22a, and for example, four screw holes 22c are formed in the flange portions 22b. Through holes 6b having an inner diameter slightly larger than the outer diameter of the rotation support member 22 are formed in the left and right side walls 6a concentrically with the central axis 22a, respectively, and a stepped portion 223 of the rotation support member 22 is formed in the through hole 6b. The small-diameter portion 221 is accommodated. A T-shaped fixing bracket 23 (indicated by a two-dot chain line in FIG. 4) is fixed around the through hole 6b in the side wall 6a, and a bolt 22e is inserted into a bolt hole 22d of the fixing bracket 23. The central shaft 22a is fixed to the side wall 6a by fastening to the screw hole 22c. Thereby, the rotation support member 22 is directly supported by the side wall 6a so that the small diameter part 221 of the stepped part 223 can be rotated in the through hole 6b. Moreover, the rotation support member 22 is indirectly supported by the side wall 6a via the fixed bracket 23 and the center shaft 22a. Further, the rotation support member 22 is restricted from moving in the left-right direction by the large-diameter portion 222 of the stepped portion 223 and the central shaft 22a.

　減速機構２４は、例えば駆動スプロケット３１よりも外径の大きい減速スプロケット２４ａを備え、駆動スプロケット３１と減速スプロケット２４ａとの間が第１減速チェーン２４ｂで連結されている。減速スプロケット２４ａの側壁６ａ側（左右内側）のスプロケット２４ｃ（図４に破線でのみ示す）と回転支持部材側スプロケット３２との間が第２減速チェーン２４ｄで連結されている。 The reduction mechanism 24 includes, for example, a reduction sprocket 24a having an outer diameter larger than that of the drive sprocket 31, and the drive sprocket 31 and the reduction sprocket 24a are connected by a first reduction chain 24b. A sprocket 24c (shown only by a broken line in FIG. 4) on the side wall 6a side (right and left inner side) of the speed reduction sprocket 24a and the rotation support member side sprocket 32 are connected by a second speed reduction chain 24d.

　一対の回転支持部材２２間には、中心軸２２ａと偏心した位置に１本の回転軸２５が回転可能に支持されている。この回転軸２５には、左右の側壁６ａ間に延びる押込板２６が回転一体に取り付けられている。図１に示すように、押込板２６は、断面について両端が尖った木の葉状の概ね平板状形態を有し、厚さ方向に対向する一対の表面２６ａには、それぞれ回転軸２５の軸心方向（車幅方向、左右方向）に間隔をあけて複数の（本実施形態では１４枚の）突条３３が配置されている。本実施形態では、各突条３３は略同形状のもので、回転軸２５の軸心方向と直交する方向に延びるように形成されている。また、突条３３は、軸心方向から見て押込板２６の表面２６ａからの高さが緩やかに変化する外周縁を有する。具体的には、突条３３は弧状の外周縁を有している。これに対応させて仕切板２１の下端部２１ｂには、各突条３３が通過する切欠部３４が形成されている。本実施形態の突条３３の断面形状は薄板状としているが、これに限定されず、強度を向上させるために断面形状を三角形や台形としてもよい。また、押込板２６の表面に凹凸を一体に形成し、その凸部分で突条３３を構成してもよい。 Between the pair of rotation support members 22, one rotation shaft 25 is rotatably supported at a position eccentric from the center shaft 22a. A push plate 26 extending between the left and right side walls 6a is attached to the rotary shaft 25 so as to be integrally rotated. As shown in FIG. 1, the pushing plate 26 has a leaf-like substantially flat plate shape with both ends sharpened with respect to the cross section, and a pair of surfaces 26 a facing in the thickness direction are respectively axial directions of the rotary shaft 25. A plurality of (in the present embodiment, 14) protrusions 33 are arranged at intervals in the vehicle width direction and the left-right direction. In this embodiment, each protrusion 33 has substantially the same shape, and is formed so as to extend in a direction orthogonal to the axial direction of the rotating shaft 25. Further, the protrusion 33 has an outer peripheral edge in which the height from the surface 26a of the pushing plate 26 gradually changes when viewed from the axial direction. Specifically, the protrusion 33 has an arcuate outer peripheral edge. Correspondingly, a notch 34 through which each protrusion 33 passes is formed at the lower end 21 b of the partition plate 21. The cross-sectional shape of the protrusion 33 of the present embodiment is a thin plate shape, but is not limited to this, and the cross-sectional shape may be a triangle or a trapezoid in order to improve the strength. Alternatively, the protrusions 26 may be integrally formed on the surface of the push plate 26 and the protrusions 33 may be formed by the protrusions.

　押込板２６は、例えば、鋼板の製缶品によって構成されている。図３及び図４に示すように、回転軸２５は、その端部に設けた押込板用減速機構２７により、回転支持部材２２が１回転する間に同方向に１／２回転するように構成されている。具体的には、押込板用減速機構２７は、中心軸２２ａに回転一体の第１スプロケット２７ａと、回転軸２５に回転一体の第２スプロケット２７ｂと、オートテンショナ２８のアイドラスプロケット２８ａとが回転調整用チェーン２７ｃで連結されている。オートテンショナ２８のレバー形状のオートテンショナ本体２８ｂが回動ピン２８ｃを中心に回転支持部材側スプロケット３２に回動可能に支持され、回動量調整ボルト２８ｄを調整することで回転調整用チェーン２７ｃの張力を調整可能となっている。オートテンショナ本体２８ｂは、張力調整後に固定ナット２８ｅによって回転支持部材側スプロケット３２に固定されるようになっている。第１スプロケット２７ａのピッチ円直径と、第２スプロケット２７ｂのピッチ円直径との比は、１：２となっている。なお、図面においては各チェーン及び各スプロケットを簡略化して描いている。 The push-in plate 26 is constituted by, for example, a steel plate can product. As shown in FIGS. 3 and 4, the rotation shaft 25 is configured to rotate half in the same direction while the rotation support member 22 makes one rotation by the pushing plate reduction mechanism 27 provided at the end thereof. Has been. Specifically, in the push-in plate speed reduction mechanism 27, a first sprocket 27a that is rotated and integrated with the central shaft 22a, a second sprocket 27b that is rotated and integrated with the rotary shaft 25, and an idler sprocket 28a of the auto tensioner 28 are adjusted for rotation. It is connected by a chain 27c. A lever-shaped auto tensioner main body 28b of the auto tensioner 28 is rotatably supported on the rotation support member side sprocket 32 around the rotation pin 28c, and the tension of the rotation adjusting chain 27c is adjusted by adjusting the rotation amount adjusting bolt 28d. Can be adjusted. The auto tensioner body 28b is fixed to the rotation support member side sprocket 32 by a fixing nut 28e after tension adjustment. The ratio of the pitch circle diameter of the first sprocket 27a and the pitch circle diameter of the second sprocket 27b is 1: 2. In the drawings, each chain and each sprocket are depicted in a simplified manner.

　このことで、図７～図１１に示すように、回転軸２５の軸心から見た押込板２６の一対の先端縁軌跡が、それぞれいわゆる略カージオイド曲線２９を描くようになっている。略カージオイド曲線２９は、心臓型の軌跡であり、この軌跡を、塵芥投入空間部６ｄの底部を形成すると共に車両の左右側面から見て円弧状の壁面６ｃに対し、沿うように配置することで、押込板２６が塵芥投入空間部６ｄの底部に投入された塵芥５５を圧縮しながら確実に仕切板２１の下方へ押し込むように構成されている。 Thus, as shown in FIGS. 7 to 11, the pair of tip edge trajectories of the pushing plate 26 viewed from the axis of the rotating shaft 25 draws a so-called substantially cardioid curve 29, respectively. The substantially cardioid curve 29 is a heart-shaped trajectory, and this trajectory is formed so as to form the bottom of the dust throwing space 6d and to follow the arcuate wall 6c as viewed from the left and right side surfaces of the vehicle. Thus, the pushing plate 26 is configured to be surely pushed down the partition plate 21 while compressing the dust 55 thrown into the bottom of the dust throwing space 6d.

　上述のように本実施形態では、押込板２６の先端縁に略カージオイド曲線２９を描かせるための機構に、側壁６ａの貫通孔６ｂに嵌め込まれる円形の回転支持部材２２を、使用している。円形の回転支持部材２２が貫通孔６ｂに嵌められることにより、側壁６ａと押込板２６との間に棒状の回転支持部材を取り付ける場合（特許文献１参照）と比較して、次の課題が解決されている。即ち、棒状の回転支持部材では押込板の回転軸心方向の有効長が短いという課題があるが、円形の回転支持部材２２では、この有効長を長くとることができる。また、棒状の回転支持部材では側壁６ａと押込板２６との間に隙間ができて塵芥が逆流しやすいという課題があるが、円形の回転支持部材２２では、側壁６ａと押込板２６との間の隙間をできるだけ小さくできる。また、棒状の回転支持部材ではねじれやすいという課題があるが、円形の回転支持部材２２では、ねじれが生じにくく、押込板２６の回転を安定させることができる。 As described above, in the present embodiment, the circular rotation support member 22 fitted into the through hole 6b of the side wall 6a is used as a mechanism for drawing the substantially cardioid curve 29 at the tip edge of the pushing plate 26. . The circular rotation support member 22 is fitted into the through-hole 6b, so that the following problem is solved as compared with a case where a rod-shaped rotation support member is attached between the side wall 6a and the pushing plate 26 (see Patent Document 1). Has been. That is, the rod-shaped rotation support member has a problem that the effective length of the pushing plate in the direction of the rotation axis is short, but the circular rotation support member 22 can increase the effective length. Further, in the rod-shaped rotation support member, there is a problem that a gap is formed between the side wall 6a and the pushing plate 26, and the dust easily flows backward. However, in the circular rotation support member 22, there is a gap between the side wall 6a and the pushing plate 26. Can be made as small as possible. In addition, the rod-shaped rotation support member has a problem of being easily twisted, but the circular rotation support member 22 is less likely to be twisted, and the rotation of the pushing plate 26 can be stabilized.

　次に、略カージオイド曲線２９は１箇所凹んだ部分（凹部２９ａ）を有するが、本実施形態では、この凹部２９ａが仕切板２１の下端部２１ｂの下端２１ｃとほぼ一致する位置に配置されている。このため、例えば図７に示す待機状態においては、回転軸２５の軸心方向から見た押込板２６の長手方向中央が下端２１ｃに近接し、図１０に示す状態では、押込板２６の先端縁が下端２１ｃに近接し、押込板２６の回転中にできるだけ下端２１ｃとの間の隙間がなくなるようになっている。このようするためには、仕切板２１の下端２１ｃの位置や押込板２６の形状について、所定の関係式を考慮しなければならない。 Next, the substantially cardioid curve 29 has a recessed portion (recessed portion 29a). In this embodiment, the recessed portion 29a is disposed at a position substantially coincident with the lower end 21c of the lower end portion 21b of the partition plate 21. Yes. Therefore, for example, in the standby state shown in FIG. 7, the longitudinal center of the pushing plate 26 viewed from the axial direction of the rotating shaft 25 is close to the lower end 21 c, and in the state shown in FIG. 10, the leading edge of the pushing plate 26 Is close to the lower end 21c, and the gap with the lower end 21c is eliminated as much as possible during the rotation of the pushing plate 26. In order to do this, a predetermined relational expression must be considered for the position of the lower end 21c of the partition plate 21 and the shape of the push plate 26.

　次に、詳しくは図示しないが、塵芥収集車１の全体構成について説明する。塵芥収集車１は、車両エンジンに駆動される発電機を備え、この発電機で得られた電力又は蓄電装置に蓄えた電力が電動モータ４６に供給されるように構成されている。図６に塵芥収集車１の油圧機器６０の油圧回路６１を示す。油圧機器６０は、電動モータ４６に駆動される油圧ポンプ４７を備えている。作動油タンク６２内の作動油は、油圧配管６４を通して油圧ポンプ４７で吸い上げられて供給側の油圧配管６１ａに流通されてコントロールバルブ６３に供給されるように構成されている。各シリンダ９，１２及び駆動モータ１４は、油圧配管６１ｂを介してコントロールバルブ６３に接続されている。コントロールバルブ６３は、図示しない複数の電磁弁を備え、電磁弁の開閉ポートを切り替えることにより、電動モータ４６を駆動して回転させた油圧ポンプ４７から吐出された作動油を所望のシリンダ９，１２又は駆動モータ１４に対して供給するように構成されている。このことで、コントロールバルブ６３を介してシリンダ９，１２の伸縮動作の切換及び駆動モータ１４の回転が制御され、又は運転が停止されるようになっている。なお、本実施形態の塵芥収集車１では、塵芥の積み込み作業時に駆動させるアクチュエータは１つの駆動モータ１４のみであり、一般的なプレス式塵芥収集車や回転板式塵芥収集車のように塵芥の積み込み作業時に複数のアクチュエータを必要とする、ということがない。 Next, although not shown in detail, the overall configuration of the garbage truck 1 will be described. The garbage collection vehicle 1 includes a generator driven by a vehicle engine, and is configured such that electric power obtained by the generator or electric power stored in a power storage device is supplied to the electric motor 46. FIG. 6 shows a hydraulic circuit 61 of the hydraulic device 60 of the garbage truck 1. The hydraulic device 60 includes a hydraulic pump 47 that is driven by the electric motor 46. The hydraulic oil in the hydraulic oil tank 62 is configured to be sucked up by the hydraulic pump 47 through the hydraulic pipe 64, distributed to the supply-side hydraulic pipe 61 a, and supplied to the control valve 63. The

cylinders

9 and 12 and the drive motor 14 are connected to the control valve 63 via a hydraulic pipe 61b. The control valve 63 includes a plurality of solenoid valves (not shown), and by switching the open / close ports of the solenoid valves, the hydraulic oil discharged from the hydraulic pump 47 rotated by driving the electric motor 46 is supplied to the desired

cylinders

9 and 12. Alternatively, it is configured to supply to the drive motor 14. Thus, the switching of the expansion and contraction operations of the

cylinders

9 and 12 and the rotation of the drive motor 14 are controlled via the control valve 63, or the operation is stopped. In the garbage collection vehicle 1 of this embodiment, only one drive motor 14 is driven during the dust loading operation, and the dust is loaded like a general press-type dust collection vehicle or a rotary plate-type dust collection vehicle. There is no need for multiple actuators during work.

　　－塵芥収集車による塵芥の収集方法－
　まず、塵芥収集車１は、塵芥５５の収集場所へ移動し、投入口７を開く。 -How to collect garbage with a garbage truck-
First, the refuse collection vehicle 1 moves to the collection place of the dust 55 and opens the insertion port 7.

　次いで、図７に示すように、押込板２６の軸心方向から見た長手方向中央の表面２６ａが仕切板２１の下端２１ｃに近接し、押込板２６の一方の先端縁が壁面６ｃの奥側端近傍に位置した状態が待機状態となっている。この待機状態で、仕切板２１の下方が塞がれているので、塵芥収容箱３に押し込まれた塵芥５５が再び塵芥投入箱６側に逆流することはない。そして、この状態で、塵芥５５を塵芥投入空間部６ｄの底部、即ち押込板２６の下方へ投入する。このとき、回転軸の位置が一定の回転板式塵芥収集車と異なり、塵芥５５の投入時には押込板２６の回転軸２５が塵芥収容箱３側へ移動し、押込板２６が投入口７から遠い位置に配置されるので、回転板式塵芥収集車よりも容積の大きい塵芥５５を投入できる。また、押込板２６の軌跡を調整することで投入口７の底辺が低く設定されているので、塵芥５５が投入しやすい。 Next, as shown in FIG. 7, the center surface 26 a in the longitudinal direction viewed from the axial direction of the push plate 26 is close to the lower end 21 c of the partition plate 21, and one tip edge of the push plate 26 is the back side of the wall surface 6 c. The state located near the end is the standby state. In this standby state, the lower part of the partition plate 21 is blocked, so that the dust 55 pushed into the dust container 3 does not flow back to the dust input box 6 again. In this state, the dust 55 is thrown into the bottom of the dust throwing space 6 d, that is, below the pushing plate 26. At this time, unlike the rotary plate-type dust collecting vehicle in which the position of the rotary shaft is constant, when the dust 55 is thrown in, the rotary shaft 25 of the push plate 26 moves to the dust container 3 side, and the push plate 26 is far from the feed port 7. Therefore, it is possible to throw in the dust 55 having a larger volume than the rotating plate type garbage truck. Moreover, since the bottom of the insertion port 7 is set low by adjusting the trajectory of the pushing plate 26, the dust 55 is easily introduced.

　次いで、駆動モータ１４を回転させると、回転支持部材２２が図７において時計回りに回転すると共に、押込板用減速機構２７の作用により、その１／２のスピードで押込板２６が時計回りに回転する。すると、図８及び図９に示すように、押込板２６が投入口７側へ回転する。このとき、略カージオイド曲線２９の凹部２９ａが仕切板２１の下端２１ｃと略一致しているため、下端２１ｃと押込板２６の表面２６ａとの間に塵芥５５が噛み込み難くなっている。しかも、突条３３が塵芥５５を押して下端２１ｃに近付けないので、さらに効果的に塵芥５５の噛み込みが防止される。 Next, when the drive motor 14 is rotated, the rotation support member 22 rotates clockwise in FIG. 7, and the pushing plate 26 rotates clockwise at half the speed by the action of the pushing plate reduction mechanism 27. To do. Then, as shown in FIG.8 and FIG.9, the pushing board 26 rotates to the insertion port 7 side. At this time, since the concave portion 29 a of the substantially cardioid curve 29 substantially coincides with the lower end 21 c of the partition plate 21, the dust 55 is difficult to bite between the lower end 21 c and the surface 26 a of the pushing plate 26. In addition, since the protrusion 33 pushes the dust 55 and does not approach the lower end 21c, the dust 55 is prevented from being bitten more effectively.

　さらに押込板２６が回転すると、図１０及び図１１に示すように、突条３３により塵芥５５が仕切板２１の下端２１ｃの下方を通って後方開口部４から塵芥収容箱３に確実に押し込まれる。このとき、塵芥投入空間部６ｄの底部を形成する壁面６ｃに対して近付くように押込板２６及び突条３３が動くので、押込板２６の回転運動のみでありながら、塵芥５５を圧縮する機能が発揮される。 When the pushing plate 26 further rotates, as shown in FIGS. 10 and 11, the dust 55 is reliably pushed into the dust container 3 from the rear opening 4 through the lower side 21 c of the partition plate 21 by the protrusion 33. . At this time, the pushing plate 26 and the ridge 33 move so as to approach the wall surface 6c forming the bottom of the dust throwing space portion 6d, so that the function of compressing the dust 55 can be achieved while only rotating the pushing plate 26. Demonstrated.

　このように、突条３３を押込板２６の各表面２６ａから突出させることで、押込板２６が回転する際に仕切板２１の下端２１ｃと押込板２６との隙間を押込板２６の表面２６ａが埋める一方、一度塵芥収容箱３側へ押し込まれた塵芥５５は、突条３３に押されて押込板２６の表面２６ａから浮いた状態にできる。また、突条３３は、仕切板２１の切欠部３４内を移動するので、突条３３を大きくしても押込板２６の回転を阻害しない。 Thus, by projecting the protrusion 33 from each surface 26a of the pushing plate 26, when the pushing plate 26 rotates, the surface 26a of the pushing plate 26 forms a gap between the lower end 21c of the partition plate 21 and the pushing plate 26. On the other hand, the dust 55 once pushed into the dust container 3 side can be pushed by the ridge 33 and floated from the surface 26 a of the pushing plate 26. Moreover, since the protrusion 33 moves in the notch 34 of the partition plate 21, even if the protrusion 33 is enlarged, the rotation of the pushing plate 26 is not hindered.

　次いで、押込板２６が１／２回転して図７の状態に戻り、反対側の表面２６ａ側で図７からの作業が繰り返される。 Next, the pushing plate 26 makes a half turn to return to the state of FIG. 7, and the operation from FIG. 7 is repeated on the opposite surface 26a side.

　本実施形態は、塵芥５５を押し込むための押込板及び塵芥５５を掻き上げるための回転板を有する一般的な回転板式と比較すると、１つの押込板２６で掻き上げ機能と押し込み機能とを発揮できるので、油圧シリンダなどのアクチュエータの数を減らすことができる。アクチュエータの数が減ることによって装置重量が軽くなり、装置重量が軽くなる分、積載容量を増やすことができる。 In this embodiment, compared with a general rotary plate type having a push plate for pushing in the dust 55 and a rotary plate for scraping up the dust 55, a single push plate 26 can exert a scraping function and a push function. Therefore, the number of actuators such as hydraulic cylinders can be reduced. By reducing the number of actuators, the weight of the apparatus is reduced, and the load capacity can be increased by the reduction in the weight of the apparatus.

　なお、これまでの一般的な回転板式塵芥収集車は、押込板と回転板という２つの部材で塵芥５５を積み込んでいたが、本実施形態のいわば遊星回転押込板式塵芥収集車１では、１枚の押込板２６だけで塵芥５５を積み込むので、同じサイクル時間では、回転板式塵芥収集車に比べて押込板２６の回転スピードを遅くすることができる。また、従来のプレス式塵芥収集車の反転下降動作や回転板式塵芥収集車の押込板の押込動作がないので、塵芥５５の積込作業で待機時間が生じないようになっている。 In addition, in the conventional rotating plate type garbage truck until now, the dust 55 was loaded by two members, the pushing plate and the rotating plate, but in the so-called planetary rotating pushing plate type garbage collecting vehicle 1 of this embodiment, there is one sheet. Since the dust 55 is loaded only by the pushing plate 26, the rotation speed of the pushing plate 26 can be reduced in the same cycle time as compared with the rotating plate type garbage truck. Further, since there is no reversing and lowering operation of the conventional press-type dust collecting vehicle and pushing-in operation of the pushing plate of the rotary plate-type dust collecting vehicle, no waiting time is generated in the loading operation of the dust 55.

　また、本実施形態は回転運動のみなのでシリンダを使用するプレス式や回転板式と比較してショックが少なく、低騒音になると共に、積込動作中電磁弁の切換がないので、低騒音になり、効率がよい。しかも、ショックレス制御、切換制御等の複雑な制御が不要であるというメリットがある。 In addition, since this embodiment is only a rotary motion, there is less shock and lower noise compared to the press type and rotary plate type using a cylinder, and since there is no switching of the solenoid valve during loading operation, it becomes low noise, Efficiency is good. In addition, there is an advantage that complicated control such as shockless control and switching control is unnecessary.

　従って、簡単な構成で、塵芥５５の逆流及び噛み込みを防止しながら塵芥５５を効率よく塵芥収容箱３へ押し込むことができる。 Therefore, with a simple configuration, the dust 55 can be efficiently pushed into the dust storage box 3 while preventing the dust 55 from flowing back and biting.

　－変形例１－
　図１２～図１５は本発明の実施形態の変形例１を示し、この変形例１は、仕切板２１の下端部２１ｂにシャッター部材３５が設けられている点で上記実施形態と異なる。なお、以下の各変形例では、図１～図１１と同じ部分については同じ符号を付してその詳細な説明は省略する。 -Modification 1-
12 to 15 show a first modification of the embodiment of the present invention, which is different from the above-described embodiment in that a shutter member 35 is provided at the lower end portion 21b of the partition plate 21. FIG. In the following modifications, the same parts as those in FIGS. 1 to 11 are denoted by the same reference numerals, and detailed description thereof is omitted.

　即ち、図１２に示すように、下端部２１ｂの各切欠部３４は、各突条３３が通過するのに伴って開閉するシャッター部材３５で覆われている。例えば、シャッター部材３５は、平板状のシャッター本体３６と、このシャッター本体３６が上下にスライドする一対のレール部材３７とを含む。シャッター本体３６の少なくとも先端（下端）側は、例えば耐摩耗性の高い樹脂成形品よりなる。各レール部材３７は、仕切板２１及び側壁６ａの少なくとも一方に取り付けられている。シャッター本体３６は、自重によりレール部材３７内を昇降してもよいが、レール部材３７の上側に付勢部材としての圧縮コイルバネ３８などを設け、シャッター部材３５を仕切板２１に沿って下端２１ｃに向けて付勢するのが望ましい。 That is, as shown in FIG. 12, each notch 34 of the lower end 21b is covered with a shutter member 35 that opens and closes as each protrusion 33 passes. For example, the shutter member 35 includes a flat shutter body 36 and a pair of rail members 37 on which the shutter body 36 slides up and down. At least the front end (lower end) side of the shutter main body 36 is made of a resin molded product having high wear resistance, for example. Each rail member 37 is attached to at least one of the partition plate 21 and the side wall 6a. The shutter main body 36 may move up and down in the rail member 37 by its own weight, but a compression coil spring 38 or the like as an urging member is provided on the upper side of the rail member 37, and the shutter member 35 is arranged on the lower end 21 c along the partition plate 21. It is desirable to urge toward.

　具体的には、図１３に示す待機状態では、突条３３が最も切欠部３４の奥深くまで入り込む。このとき、シャッター部材３５も最も高い位置まで押し上げられ、圧縮コイルバネ３８は最も圧縮される。 Specifically, in the standby state shown in FIG. 13, the protrusion 33 enters the deepest part of the notch 34. At this time, the shutter member 35 is also pushed up to the highest position, and the compression coil spring 38 is compressed most.

　そして、押込板２６が９０度回転すると、図１４に示すように、押込板２６の一端が下端２１ｃの位置に移動する。このとき、圧縮コイルバネ３８に押されたシャッター部材３５は、下端２１ｃまで下降して切欠部３４略全体を覆う。圧縮コイルバネ３８は最も伸びた状態となる。 Then, when the pushing plate 26 rotates 90 degrees, as shown in FIG. 14, one end of the pushing plate 26 moves to the position of the lower end 21c. At this time, the shutter member 35 pushed by the compression coil spring 38 descends to the lower end 21c and covers substantially the entire notch 34. The compression coil spring 38 is in the most extended state.

　次いで、図１５に示すように、さらに押込板２６が回転すると、シャッター部材３５が再び押し上げられる。 Next, as shown in FIG. 15, when the pushing plate 26 further rotates, the shutter member 35 is pushed up again.

　このように、突条３３が切欠部３４を通過するときにシャッター部材３５を押し上げて開き、通過後にシャッター部材３５が自重及び圧縮コイルバネ３８の付勢力で確実に閉じるので、切欠部３４から塵芥５５が逆流することはない。 Thus, when the protrusion 33 passes through the notch 34, the shutter member 35 is pushed up and opened, and after passing, the shutter member 35 is securely closed by its own weight and the urging force of the compression coil spring 38. Will not flow backwards.

　－変形例２－
　図１６～図１８に示すように、突条３３の回転軸２５の軸心からの最大高さＨｍａｘを回転軸２５の軸心方向（左右方向）中央で最も高く、中央から離れるにつれて低くしてもよい。図１７に示すように、最大高さＨｍａｘは、押込板２６の一対の先端縁を結ぶ方向（図１７の手前）から見て回転軸２５の軸心から突条３３の頂点までの高さを意味する。このように構成することで、左右方向中央に偏って塵芥投入空間部６ｄの底方に投入された塵芥５５が突条３３によって両側壁６ａ側へ掻き分けられるので、塵芥収容箱３に均等に押し込まれる。このため、複数の突条３３に高さの変化をもたせない場合と比較して、塵芥収容箱３に積載できる塵芥５５の量を増やすことができる。 -Modification 2-
As shown in FIGS. 16 to 18, the maximum height Hmax of the protrusion 33 from the axis of the rotating shaft 25 is the highest in the center in the axial direction (left-right direction) of the rotating shaft 25, and is lowered as the distance from the center increases. Also good. As shown in FIG. 17, the maximum height Hmax is the height from the axis of the rotary shaft 25 to the apex of the ridge 33 as seen from the direction connecting the pair of tip edges of the push plate 26 (front of FIG. 17). means. With this configuration, the dust 55 that is biased to the center in the left-right direction and is thrown into the bottom of the dust throwing space 6d is scraped to the side walls 6a by the protrusions 33, so that it is equally pushed into the dust storage box 3. It is. For this reason, compared with the case where the height change is not given to the some protrusion 33, the quantity of the dust 55 which can be loaded in the dust storage box 3 can be increased.

　そして、図１９に示すように、上記変形例１と同様にシャッター部材１３５を設けてもよい。例えば、各突条３３に対応させて分割されたシャッター部材１３５を設け、各シャッター部材１３５を個別に上下スライド可能に構成してもよい。この場合、隣り合うシャッター部材１３５間は、図示しない連結レール部にて連結されており、相互に相対的スライド移動可能に連結されている。また、圧縮コイルバネ３８を各レール部材３７に設け、各シャッター部材１３５の上端をベルトなどの帯状体（図示せず）で押さえ付けるようにすれば、各シャッター部材１３５のスライド量が異なっても全てのシャッター部材１３５が下方へ付勢される。 And as shown in FIG. 19, you may provide the shutter member 135 similarly to the said modification 1. As shown in FIG. For example, the shutter member 135 divided | segmented corresponding to each protrusion 33 may be provided, and each shutter member 135 may be comprised so that an up-down slide is possible individually. In this case, the adjacent shutter members 135 are connected to each other by a connecting rail portion (not shown) and are connected to each other so as to be capable of relative sliding movement. Further, if a compression coil spring 38 is provided on each rail member 37 and the upper end of each shutter member 135 is pressed by a belt-like body (not shown) such as a belt, all the slide members 135 have different slide amounts. The shutter member 135 is urged downward.

　－変形例３－
　図２０及び図２１に示すように、押込板２６の一対の先端縁を結ぶ方向（図２１の手前）から見た突条３３の回転軸２５の軸心からの最大高さＨｍａｘを、左右方向中央で最も低く、中央から離れるにつれて高くしてもよい。このように構成すれば、側壁６ａ側に偏って塵芥投入空間部６ｄの底方に投入された塵芥５５が突条３３によって左右方向中央に掻き集められるので、左右のバランスが保たれ、塵芥収容箱３に均等に押し込まれる。このため、塵芥収容箱３に積載できる塵芥５５の量が増える。 -Modification 3-
As shown in FIGS. 20 and 21, the maximum height Hmax from the axis of the rotation shaft 25 of the ridge 33 viewed from the direction connecting the pair of tip edges of the push plate 26 (front of FIG. 21) is determined in the left-right direction. It may be the lowest at the center and higher as the distance from the center increases. With this configuration, the dust 55 that is biased toward the side wall 6a and is thrown into the bottom of the dust throwing space 6d is scraped to the center in the left-right direction by the protrusion 33, so that the left-right balance is maintained, and the dust storage box 3 evenly. For this reason, the quantity of the dust 55 which can be loaded in the dust storage box 3 increases.

　本変形例でも上記変形例２のようにシャッター部材１３５を設けてもよい。 In the present modification, the shutter member 135 may be provided as in the second modification.

　－変形例４－
　図２２及び図２３に示すように、押込板２６の一対の先端縁を結ぶ方向（図２３の手前）から見た突条３３の回転軸２５の軸心からの最大高さＨｍａｘを左右方向中央で最も低く、中央から離れるにつれて一端高くなり、再び低くしてもよい。このように構成すれば、塵芥投入空間部６ｄの底方に投入された塵芥５５が突条３３によって両側壁６ａ側及び左右中央に掻き分けられるので、塵芥収容箱３に均等に押し込まれる。このため、複数の突条３３に高さの変化をもたせない場合と比較して、塵芥収容箱３に積載できる塵芥５５の量を増やすことができる。 -Modification 4-
As shown in FIGS. 22 and 23, the maximum height Hmax from the axis of the rotating shaft 25 of the ridge 33 viewed from the direction connecting the pair of tip edges of the pushing plate 26 (front of FIG. 23) is the center in the left-right direction. It may be the lowest at a certain point, become higher as it goes away from the center, and lower again. If comprised in this way, since the dust 55 thrown into the bottom of the dust throwing-in space part 6d will be scraped off into the both-side wall 6a side and the left-right center by the protrusion 33, it will be equally pushed into the dust storage box 3. For this reason, compared with the case where the height change is not given to the some protrusion 33, the quantity of the dust 55 which can be loaded in the dust storage box 3 can be increased.

　－変形例５－
　図２４及び図２５に示すように、押込板２６の一対の先端縁を結ぶ方向（図２５の手前）から見て、押込板２６の一方の表面２６ａに設けた突条３３の回転軸２５の軸心からの最大高さＨｍａｘを左右方向中央で最も高く、中央から離れるにつれて低くし、他方の表面２６ａに設けた突条３３の回転軸２５の軸心からの最大高さＨｍａｘを左右方向中央で最も低く、中央から離れるにつれて高くしてもよい。このように構成すると、塵芥投入空間部６ｄの底方に投入された塵芥５５は、押込板２６が回転するごとに一方の面の突条３３によって両側壁６ａ側へ掻き分けられ、次ぎに他方の面の突条３３によって左右中央側へ掻き集め、さらにこの順番で振り分けが繰り返されるので、塵芥５５が塵芥収容箱３に均等に押し込まれる。このため、複数の突条３３に高さの変化をもたせない場合と比較して、塵芥収容箱３に積載できる塵芥５５の量を増やすことができる。 -Modification 5-
As shown in FIGS. 24 and 25, the rotating shaft 25 of the protrusion 33 provided on one surface 26 a of the pushing plate 26 is viewed from the direction connecting the pair of leading edges of the pushing plate 26 (front side in FIG. 25). The maximum height Hmax from the shaft center is the highest at the center in the left-right direction, and is lowered as it goes away from the center, and the maximum height Hmax from the shaft center of the rotating shaft 25 of the protrusion 33 provided on the other surface 26a is the center in the left-right direction. It may be the lowest and the higher it is from the center. If comprised in this way, the dust 55 thrown into the bottom of the dust throwing-in space part 6d will be scraped off to the both-side wall 6a side by the protrusion 33 of one side, whenever the pushing plate 26 rotates, and then the other side. The surface protrusions 33 scrape up the left and right central sides, and the sorting is repeated in this order, so that the dust 55 is pushed evenly into the dust container 3. For this reason, compared with the case where the height change is not given to the some protrusion 33, the quantity of the dust 55 which can be loaded in the dust storage box 3 can be increased.

　－変形例６－
　図２６及び図２７に示すように、押込板２６の一対の先端縁を結ぶ方向（図２７の手前）から見て、押込板２６の一方の表面２６ａに設けた突条３３の回転軸２５の軸心からの最大高さＨｍａｘを左右方向一端側が最も高く、他端側へ向かうにつれて低くし、押込板２６の他方の表面２６ａに設けた突条３３の回転軸２５の軸心からの最大高さＨｍａｘを左右方向他端側が最も高く、一端側へ向かうにつれて低くしてもよい。 -Modification 6-
As shown in FIGS. 26 and 27, the rotating shaft 25 of the protrusion 33 provided on the one surface 26 a of the pushing plate 26 is viewed from the direction connecting the pair of leading edges of the pushing plate 26 (front side in FIG. 27). The maximum height Hmax from the shaft center is the highest at one end in the left-right direction and is lowered toward the other end, and the maximum height from the shaft center of the rotating shaft 25 of the ridge 33 provided on the other surface 26a of the pushing plate 26. The height Hmax may be highest at the other end in the left-right direction, and may decrease as it goes toward one end.

　このように構成すると、塵芥投入空間部６ｄの底方に投入された塵芥５５は、押込板２６が回転するごとに一方の面の突条３３によって一方の側壁６ａ側へ掻き集められ、他方の面の突条３３によって他方の側壁６ａ側へ掻き集められるので、塵芥収容箱３に均等に押し込まれる。このため、複数の突条３３に高さの変化をもたせない場合と比較して、塵芥収容箱３に積載できる塵芥５５の量を増やすことができる。 If comprised in this way, the dust 55 thrown into the bottom of the dust throwing-in space part 6d will be scraped up to the one side wall 6a side by the protrusion 33 of one side, whenever the pushing board 26 rotates, and the other side Since the ridges 33 are scraped to the other side wall 6a, they are evenly pushed into the trash storage box 3. For this reason, compared with the case where the height change is not given to the some protrusion 33, the quantity of the dust 55 which can be loaded in the dust storage box 3 can be increased.

　－変形例７－
　図２８及び図２９に示すように、回転軸２５の軸心方向（図２９の左右方向）から見て、複数の突条３３を押込板２６の厚さ方向に対向する一対の表面２６ａにおける、一方の表面２６ａの長手方向一端側と他方の表面２６ａの長手方向他端側とに設けてもよい。この突条３３は、押込板２６の先端縁が塵芥投入空間部６ｄの底部を形成する壁面６ｃに沿って移動するときに投入口７側となるようにそれぞれ形成されている。そして、各突条３３は、各表面２６ａの長手方向中央から一端側又は他端側へ向かうにつれて該各表面２６ａから離れるように傾斜する傾斜面３３ａを有する。 -Modification 7-
As shown in FIGS. 28 and 29, when viewed from the axial direction of the rotating shaft 25 (the left-right direction in FIG. 29), the plurality of protrusions 33 on the pair of surfaces 26 a facing the thickness direction of the pushing plate 26, You may provide in the longitudinal direction one end side of the one surface 26a, and the longitudinal direction other end side of the other surface 26a. Each of the protrusions 33 is formed so that the leading edge of the pushing plate 26 is on the inlet 7 side when it moves along the wall surface 6c that forms the bottom of the dust inlet space 6d. And each protrusion 33 has the inclined surface 33a which inclines so that it may leave | separate from each said surface 26a as it goes to the one end side or the other end side from the longitudinal direction center of each surface 26a.

　言い換えれば、例えば図３３に示す垂直状態の押込板２６を回転軸２５の軸心方向から見て、一対の表面２６ａにおける車両前方側の表面２６ａの上端側と、車両後方側の表面２６ａの下端側とに同形の突条３３がそれぞれ軸心方向に間隔をあけて配置されている。そして、各突条３３は、車両前方側の表面２６ａの上下方向中央から上端側へ又は車両後方側の表面２６ａの上下方向中央から下端側へ向かうにつれて各表面２６ａから離れるように傾斜する傾斜面３３ａを有する。 In other words, for example, when the pushing plate 26 in the vertical state shown in FIG. 33 is viewed from the axial direction of the rotary shaft 25, the upper end side of the surface 26a on the vehicle front side and the lower end of the surface 26a on the vehicle rear side of the pair of surfaces 26a. On the side, protrusions 33 having the same shape are arranged at intervals in the axial direction. Each protrusion 33 is an inclined surface that is inclined so as to be separated from each surface 26a from the center in the vertical direction of the surface 26a on the front side of the vehicle toward the upper end side or from the center in the vertical direction of the surface 26a on the vehicle rear side toward the lower end side. 33a.

　このように構成すれば、図３２に示すように、下側に表面２６ａと、その表面２６ａに連続する上側の突条３３の傾斜面３３ａとで塵芥５５を押さえ付けながら、図３３のように塵芥が圧縮され、図３４に示すように、塵芥５５が塵芥収容箱３に押し込まれる。このように、本変形例の突条３３は、塵芥５５の圧縮効果を発揮することができる。 If comprised in this way, as shown in FIG. 32, pressing down the dust 55 with the surface 26a on the lower side and the inclined surface 33a of the upper protrusion 33 continuing to the surface 26a, as shown in FIG. The dust is compressed, and the dust 55 is pushed into the dust container 3 as shown in FIG. Thus, the protrusion 33 of this modification can exhibit the compression effect of the dust 55.

　（その他の実施形態）
　本発明は、上記実施形態について、以下のような構成としてもよい。 (Other embodiments)
The present invention may be configured as follows with respect to the above embodiment.

　即ち、上記実施形態では、塵芥収集装置を電動の塵芥収集車１に備えた例を示したが、この塵芥収集装置は、ビルや工場などの床に固定設置するものであってもよい。具体的には、塵芥収集装置を車体フレーム２ｂ上ではなく床に載置されるフレーム上に載置すればよい。 That is, in the above-described embodiment, the example in which the dust collecting device is provided in the electric dust collecting vehicle 1 is shown, but this dust collecting device may be fixedly installed on the floor of a building or a factory. Specifically, the dust collecting device may be placed not on the body frame 2b but on a frame placed on the floor.

　上記実施形態では、押込板２６を駆動させる機構は、チェーン機構で構成しているが、歯車を直結して駆動させるようにしてもよい。 In the above embodiment, the mechanism for driving the pushing plate 26 is a chain mechanism, but it may be driven by directly connecting gears.

　上記実施形態では、電動モータを用いて油圧ポンプを駆動させる塵芥収集車１の例を示しているが、塵芥収集装置は、電動モータではなく、エンジンの駆動力を動力取り出し装置（ＰＴＯ）を介して油圧ポンプに伝達するものでもよい。回転支持部材２２の駆動方法についても、本実施形態では、油圧の駆動モータ１４の動力を減速させて駆動しているようにしているが、電動モータ４６の動力を用いてもよい。これら駆動モータ１４や電動モータ４６の動力源も特に限定されない。 In the above embodiment, an example of the dust collection vehicle 1 that drives the hydraulic pump using an electric motor is shown. However, the dust collection device is not an electric motor, but uses the driving force of the engine via a power take-out device (PTO). And may be transmitted to a hydraulic pump. Regarding the method for driving the rotation support member 22, in the present embodiment, the driving force of the hydraulic drive motor 14 is decelerated, but the driving force of the electric motor 46 may be used. The power source of these drive motor 14 and electric motor 46 is not particularly limited.

　また、上記実施形態では、駆動モータ１４を左右一方の側壁の内側に取り付けたが、駆動モータは左右の側壁の両方に設けてもよい。また、駆動モータ１４の出力軸１４ａと駆動スプロケット３１との間に遊星歯車減速機ユニットを介してもよい。 In the above embodiment, the drive motor 14 is attached to the inside of one of the left and right side walls, but the drive motor may be provided on both the left and right side walls. Further, a planetary gear reducer unit may be interposed between the output shaft 14 a of the drive motor 14 and the drive sprocket 31.
