Abstract

PROBLEM TO BE SOLVED: To efficiently push refuse into a refuse storage box while preventing a backflow and biting of refuse with a simple configuration.SOLUTION: A partition plate 21 is disposed between a refuse cast box and the refuse storage box, and a refuse loading mechanism 20 is disposed for compressing the refuse input from a cast port 7 of the refuse cast box and pushing the compressed refuse from below the partition plate 21 to the rear opening side. The refuse loading mechanism 20 rotatably supports a pair of rotation support members 22 on a pair of side walls 6a of the refuse input box respectively, and rotatably supports a pushing plate 26 around a rotary shaft 25 provided between the rotation support members 22 eccentrically between the pair of the rotation support members 22. While each of the rotation support members 22 makes 1 revolution, the pushing plate 26 makes 1/2 of a revolution in the same direction, causing a leading edge locus as viewed from the direction of the shaft center of the rotary shaft 25 to draw a cardioid curve. A swelling part 26a is formed in the pushing plate 26 so as to fill a gap between the lower end 21c of the partition plate 21 and the middle in a longitudinal direction of the pushing plate 26 as viewed from the direction of the shaft center of the rotary shaft 25.

Description

本発明は、塵芥投入箱に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 put into a dust throwing box and pushes the dust into a dust containing box, and a dust collecting vehicle equipped with the dust collecting device.

従来より、塵芥収容箱の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、塵芥投入箱に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 opening of the dust storage box, the partition plate provided on the front side of this dust input box, and the dust input to the dust input box are compressed. There is known a garbage truck equipped with a dust loading mechanism that pushes into the dust container box 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装設している。   For example, in Patent Document 1, a dust input box connected to a rear opening of a dust storage box, a rotating body pivotally attached to a side wall of the input box, and a first power for rotating the rotating body by a rotation driving device. The transmission mechanism, the pushing plate that is erected and supported on the rotating body so as to be rotatable at a position eccentric to the shaft attachment portion of the rotating body, and the rotational speed in the same direction as the rotating body and 1/2 of the rotational speed of the rotating body. As described above, there is known a garbage collection vehicle that includes a second power transmission mechanism that rotates the pushing plate relative to the rotating body and causes the pushing plate to revolve and rotate. In this garbage collection vehicle, a biting prevention means is installed at the lower part of a partition plate (fixed plate) fixed to the upper part of the dust input box.

特開昭55−44476号公報JP 55-44476 A

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専用の駆動用モータを設けたり、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たりしなければならず、その分だけ部品が増え、故障の可能性や製造費用が増加するという問題がある。   However, in the garbage collection vehicle of the above-mentioned Patent Document 1, as a biting prevention means, a biting prevention roller and a dedicated drive motor are provided at the lower part of the partition plate, or a shielding plate that is always in contact with the surface of the pushing plate and There is a problem that a spring for energizing must be provided, and the number of parts increases accordingly, which increases the possibility of failure and the manufacturing cost.

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、押込板の軸心方向から見て先端縁がカージオイド曲線を描くように回転可能に支持させ、仕切板下端と押込板の長手方向中間との間を埋める膨出部を設けた。   In order to achieve the above object, according to the present invention, the push plate is rotatably supported so that the tip edge draws a cardioid curve when viewed from the axial direction of the push plate, and the lower end of the partition plate and the length of the push plate are supported. The bulging part which filled between the direction middle was provided.

具体的には、第1の発明では、塵芥収容箱と、該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 invention, a dust container box, a dust container box connected to the opening part of the dust container box, a partition plate provided on the side of the dust container box facing the opening part, An object of the present invention is a dust collecting apparatus provided with a dust loading mechanism that is provided in the dust throwing box and compresses the dust thrown from 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回転し、上記回転軸の軸心方向から見た一対の先端縁の軌跡がそれぞれカージオイド曲線を描く押込板とを備え、
上記軸心方向から見て、上記仕切板の下端と上記押込板の長手方向中間との隙間を埋めるように該押込板には膨出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 in which the trajectories of the pair of leading edges viewed from the axial direction of the rotating shaft each draw a cardioid curve,
As seen from the axial direction, a bulging portion is formed on the pushing plate so as to fill a gap between the lower end of the partition plate and the middle in the longitudinal direction of the pushing plate.

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、仕切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、押込板の膨出部が、回転軸の軸心方向から見て仕切板の下端と押込板の長手方向中間との隙間を埋めるので、一度塵芥収容箱側へ押し込まれた塵芥は、膨出部があるために塵芥投入箱側へ逆流しない。   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 surface of the partition 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 switching sounds are generated when switching to each process such as compression and pushing, as in the so-called press dust collecting device and rotating plate collecting device. do not do. Since the bulging part of the pushing plate fills the gap between the lower end of the partition plate and the middle in the longitudinal direction of the pushing plate when viewed from the axial direction of the rotating shaft, the dust once pushed into the dust container box side is swollen. Due to the exit, it does not flow backward to the dust box.

第2の発明では、第1の発明において、
上記膨出部は、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、該膨出部は、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 second invention, in the first invention,
The bulging portion includes a longitudinal direction one end side of one surface and a longitudinal other end side 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. The leading edge of the pushing plate is formed so as to be on the inlet side when moving along the wall surface forming the bottom of the dust throwing space portion, and the bulging portion is formed on the surface of the surface. It has an inclined surface which inclines so that it may leave | separate from each said surface as it goes to the said one end side or the said other end side from a longitudinal direction center.

上記の構成によると、押込板の厚さ方向に対向する一対の表面に、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、膨出部をそれぞれ設けることにより、押込板における下方に位置する表面と上方に位置する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。   According to the above configuration, when the leading edge of the push plate moves along the wall surface forming the bottom of the dust throwing space portion on the pair of surfaces opposed to the thickness direction of the push plate, the push plate comes to be on the inlet side. In addition, by providing each of the bulging portions, the dust is efficiently passed between the lower surface of the pushing plate and the inclined surface positioned on the upper side while the dust is efficiently passed through the lower portion of the partition plate. Is pushed into.

第3の発明の塵芥収集車は、第1又は第2の発明の塵芥収集装置を車体後部に備える構成とする。   The refuse collection vehicle of 3rd invention sets it as the structure which equips the vehicle body rear part with the dust collection apparatus of 1st or 2nd invention.

上記の構成によると、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, the number of actuators is reduced and switching sound is generated when switching to each process, such as compression and pushing, as compared with a general press-type dust collection vehicle and a rotating plate-type dust collection vehicle. By eliminating the control, it is possible to reduce the weight, simplify the structure and reduce the noise, and further prevent the dust from flowing back and biting into the dust collecting vehicle with less trouble.

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、回転軸の軸心方向から見て一対の先端縁の軌跡がカージオイド曲線を描くようにし、回転軸の軸心方向から見て仕切板の下端と押込板の長手方向中間との隙間を埋めるように押込板から膨出部を膨出させたことにより、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. Rotate the pusher plate in half in the same direction during one rotation of the shaft so that the locus of the pair of tip edges draws a cardioid curve when viewed from the axial direction of the rotating shaft. By bulging the bulging part from the pushing plate so as to fill the gap between the lower end of the partition plate and the longitudinal direction of the pushing plate, the dust can be removed while preventing the dust from flowing back and biting with a simple structure. It can be pushed into the waste storage box efficiently.

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の車体2上に塵芥収容箱3が搭載されている。車体2の前側には、運転台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、車体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、車体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 equipped with a dust collection device according to an embodiment of the present invention. A dust storage box 3 is mounted on a vehicle body 2 of the dust collection vehicle 1. A driver's cab 2 a is provided on the front side of the vehicle body 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 axis on the rear side of the vehicle body 2 by extending and contracting a tilt cylinder 12 (shown only in FIG. 6) provided in the vehicle body 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 therein. The dust loading mechanism 20 is for compressing and loading the dust 55 put into the dust throwing box 6 through the throwing 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、例えは、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 container 6 so as to extend from above. The partition plate 21 separates the dust throwing space 6 d in the dust throwing box 6 from the inside of the dust receiving box 3. For example, the connecting plate 21 covers the upper half of the rear opening 4 of the dust receiving box 3. It includes a portion 21a and a lower end 21b that 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、例えば円板よりなる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 rotation support members 22 made of, for example, discs, which are rotatably supported by the pair of opposed side walls 6 a of the dust box 6. I have. 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.

円板状の回転支持部材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 disk-shaped 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。   A disc-shaped flange 22b is 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 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. 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。押込板26は、概ね平板状形態を有し、例えば図10に示す上下に立った状態において回転軸の軸心方向から見て、厚さ方向に対向する一対の表面26bにおける車両前方側の表面26bの上端側と、車両後方側の表面26bの下端側とに回転軸25に沿って(奥行き方向に)それぞれ膨出した膨出部26aが形成されている。そして、膨出部26aは、車両前方側の表面26bの上下方向中央から上端側へ又は車両後方側の表面26bの上下方向中央から下端側へ向かうにつれて各表面26bから離れるように傾斜する傾斜面26cを有する。言い換えれば、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側となるように膨出部26aがそれぞれ膨出している。   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. The pushing plate 26 has a substantially flat plate shape. For example, when viewed from the axial direction of the rotating shaft in the state of standing up and down as shown in FIG. A bulging portion 26a that bulges along the rotation shaft 25 (in the depth direction) is formed on the upper end side of the vehicle 26b and the lower end side of the surface 26b on the vehicle rear side. And the bulging part 26a is an inclined surface which inclines so that it may leave | separate from each surface 26b as it goes to the upper end side from the vertical direction center of the surface 26b of the vehicle front side, or the vertical direction center of the surface 26b of the vehicle rear side. 26c. In other words, each of the bulging portions 26a bulges so that the leading edge of the push-in plate 26 moves along the wall surface 6c forming the bottom of the dust throwing space portion 6d so as to be on the loading port 7 side.

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。このことで、図7〜図13に示すように、回転軸25の軸心から見た押込板26の先端縁軌跡が、それぞれいわゆるカージオイド曲線29を描くようになっている。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。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 pushing plate 26 is made of, 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. As a result, as shown in FIGS. 7 to 13, the tip edge trajectory of the pushing plate 26 as viewed from the axis of the rotating shaft 25 draws a so-called cardioid curve 29. The cardioid curve 29 is a heart-shaped trajectory, and this trajectory is formed by forming the bottom of the dust throwing space 6d and along the arcuate wall 6c when viewed from the left and right side surfaces of the vehicle. The 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. In the drawings, each chain and each sprocket are depicted in a simplified manner.

本実施形態では、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、この凹部29aは、仕切板21の下端21cから若干ずれた位置に配置されている。このため、仕切板21の下端21cと押込板26の長手方向中間との間には、図11に示すように、隙間cが形成されている。この隙間cは、膨出部26aが押込板26の各表面26bに回転軸25を中心に180°ずれた位置に形成されていることによって、押込板26の回転に合わせて塞がれるようになっている。   In the present embodiment, the cardioid curve 29 has a recessed portion (recessed portion 29 a), but this recessed portion 29 a is disposed at a position slightly shifted from the lower end 21 c of the partition plate 21. Therefore, a gap c is formed between the lower end 21c of the partition plate 21 and the middle in the longitudinal direction of the pushing plate 26, as shown in FIG. The gap c is formed so that the bulging portion 26 a is formed on each surface 26 b of the push plate 26 at a position shifted by 180 ° about the rotation shaft 25, so that it is closed in accordance with the rotation of the push plate 26. It has become.

一方、詳しくは図示しないが、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。   On the other hand, although not shown in detail, the garbage truck 1 includes a generator driven by a vehicle engine so that electric power obtained by the generator or electric power stored in the power storage device is supplied to the electric motor 46. It is configured. 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.

−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 dust 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がほぼ水平になった状態で、塵芥55を押込板26の下方へ投入する。このとき、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 dust 55 is thrown into the lower side of the pushing plate 26 in a state where the pushing plate 26 is substantially horizontal. At this time, since the bottom of the insertion port 7 is set low by adjusting the trajectory of the push-in 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において時計周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の平坦な表面26bで塵芥55を下方へ押し込み、さらに上方にある傾斜面26cで塵芥55の上方が押さえ込まれるので、塵芥55が適度に圧縮されながら塵芥収容箱3側へ移動する。   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 dust 55 is pushed downward by the flat surface 26b of the pushing plate 26, and the upper portion of the dust 55 is pushed by the upper inclined surface 26c. It moves to the dust container 3 side while being compressed.

次いで、図10に示すように、押込板26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に押し込まれる。   Next, as shown in FIG. 10, the dust plate 55 is pushed into the dust container box 3 from the rear opening 4 through the lower side 21 c of the partition plate 21 by the push plate 26.

次いで、図11に示すように、塵芥55が表面26b及び傾斜面26cで効果的に圧縮されながら押し込まれる。同時に膨出部26a(傾斜面26c)の頂点がほぼ仕切板21の下端21cまで移動するので、押し込まれた塵芥55が逆流してくることはない。   Next, as shown in FIG. 11, the dust 55 is pushed in while being effectively compressed by the surface 26b and the inclined surface 26c. At the same time, the apex of the bulging portion 26a (inclined surface 26c) moves to almost the lower end 21c of the partition plate 21, so that the pushed-in dust 55 does not flow backward.

次いで、図12及び図13に示すように、押込板26の先端で塵芥55をさらに塵芥収容箱3側へ押し込む。この間に新たに押込板26の下方へ塵芥55を投入する。   Next, as shown in FIGS. 12 and 13, the dust 55 is further pushed into the dust container 3 side at the tip of the pushing plate 26. In the meantime, the dust 55 is newly put below the pushing plate 26.

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26bで図6からの作業が繰り返される。   Next, the pushing plate 26 rotates 1/2 and returns to the state of FIG. 7, and the operation from FIG. 6 is repeated on the opposite surface 26b.

このように押込板26が連続的に回転して塵芥の押込作業を行うので、日本で一般的なプレス式塵芥車や回転板式塵芥車のように各工程に切り換わるときの切換音が発生しない。そして、押込板26の膨出部26aが、回転軸の軸心方向から見て仕切板21の下端21cと押込板26の長手方向中間との隙間cを埋めるので、一度塵芥収容箱3側へ押し込まれた塵芥は、膨出部26aがあるために塵芥投入箱6側へ逆流しない。   In this way, the pushing plate 26 is continuously rotated to perform the dust pushing operation, so that the switching sound is not generated when switching to each process as in the case of a press-type dust wheel and a rotary plate-type dust wheel that are common in Japan. . Since the bulging portion 26a of the pushing plate 26 fills the gap c between the lower end 21c of the partition plate 21 and the middle in the longitudinal direction of the pushing plate 26 when viewed from the axial direction of the rotation shaft, the bulging portion 26a once moves toward the dust container 3 side. The pushed-in dust does not flow backward to the dust input box 6 because of the bulging portion 26a.

したがって、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。   Therefore, with a simple configuration, the dust can be efficiently pushed into the dust container box while preventing the dust from flowing back and biting.

However, the 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. However, the gear may be driven directly.

However, the dust collection device may be one that takes out the output of the engine from the hydraulic pump via a power take-out device (PTO) instead of being electrically driven. Regarding the method for driving the rotation support member 22, in this embodiment, the power of the drive motor 14 is decelerated and driven, but the power of the electric motor 46 may be used.

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.

上記実施形態のように傾動シリンダ12を設けて塵芥収容箱3をダンプ可能に構成するのではなく、塵芥収容箱3に塵芥収容箱3内の塵芥を排出する排出装置を設けてもよい。具体的には、塵芥収容箱3内に排出板を前後方向に摺動自在に配設し、排出シリンダの伸縮動作により塵芥収容箱3内を前後に摺動するようにすればよい。   Instead of providing the tilt cylinder 12 and dumping the dust storage box 3 as in the above embodiment, the dust storage box 3 may be provided with a discharge device for discharging the dust in the dust storage box 3. Specifically, a discharge plate may be slidable in the front-rear direction in the dust storage box 3, and may be slid back and forth in the dust storage box 3 by an expansion / contraction operation of the discharge cylinder.

上記実施形態では、回転支持部材を円板で構成しているが、棒状、板状のリンクで構成してもよい。要は、中心軸22aを中心に回転し、この中心軸22aから偏心した位置で回転軸25を支える剛性の高い部材であればよい。   In the said embodiment, although the rotation support member is comprised with the disc, you may comprise with a rod-shaped and plate-shaped link. In short, any member may be used as long as it rotates around the central axis 22a and supports the rotary shaft 25 at a position eccentric from the central axis 22a.
