特許文献1に記載の塵芥収集車において、積込装置の押込板は、前プレートのうち下端寄りの領域を主な押込み面として塵芥を前方へ押すよう、揺動中心軸回りに揺動される。また、積込装置の押込板では、後プレートの下端と下方補強部材の上角部とが溶接されて一体化されている。 In the dust collecting vehicle described in Patent Document 1, the pushing plate of the loading device is swung around the swing center axis so as to push the dust forward with the region near the lower end of the front plate as the main pushing surface. .. Further, in the push-in plate of the loading device, the lower end of the rear plate and the upper corner portion of the lower reinforcing member are welded and integrated.

特許文献1に記載の塵芥収集車の積込装置において、押込板が揺動中心軸回りに揺動して塵芥を前方へ押す動作に伴い、塵芥により前プレートの押込み面が反力としての負荷を受ける。そして、この負荷により前プレートとともにこれに一体化されている下方補強部材および後プレートが撓むように変形すると、下方補強部材の上角部と後プレートの下端との溶接部分に応力が集中して、溶接部分が破損してしまう。 In the loading device of the dust collecting vehicle described in Patent Document 1, as the pushing plate swings around the swing center axis and pushes the dust forward, the pushing surface of the front plate is loaded as a reaction force by the dust. Receive. Then, when the lower reinforcing member and the rear plate integrated with the front plate are deformed so as to bend due to this load, stress is concentrated on the welded portion between the upper corner portion of the lower reinforcing member and the lower end of the rear plate. The welded part will be damaged.

そこで本発明は、積込装置における、補強部材と後プレートの溶接部分の破損を防止し得る塵芥収集車の提供を目的とする。 Therefore, an object of the present invention is to provide a dust collecting vehicle capable of preventing damage to the welded portion between the reinforcing member and the rear plate in the loading device.

本発明の塵芥収集車は、塵芥を収容する収容空間を有した塵芥収容箱と、塵芥の投入口を有して前記塵芥収容箱の後方に連接された塵芥投入箱と、前記投入口から投入された塵芥を前記収容空間へ移動させる積込装置とを備え、該積込装置は、前記塵芥投入箱に投入された塵芥を掻上げるよう移動させるべく回転する回転板と、該回転板によって掻上げられた塵芥を前記収容空間に押込むよう移動させる押込板とを備え、前記回転板および押込板は、塵芥を移動させる方向である前方に配置されて前記塵芥投入箱の幅方向に延長された前プレートを備え、前記回転板および押込板のうちの少なくとも一方は、前プレートの背面側に固定されて幅方向に延長された補強プレートを有する一対の補強部材と、前記補強プレートどうしに渡して固定され幅方向に延長された後プレートとを備え、該後プレートは、前記補強プレートの間にあって幅方向に亘って折曲した折曲部を備えるとともに、前記補強部材側の端部が、前記一対の補強部材のうちの少なくとも一方の補強部材の補強プレートの背面に平行な状態で重ねられて前記補強プレートに溶接されていることを特徴としている。 The dust collecting vehicle of the present invention includes a dust storage box having a storage space for storing dust, a dust storage box having a dust charging port and connected to the rear of the dust storage box, and loading from the loading port. The loading device is provided with a loading device for moving the collected dust to the accommodation space, and the loading device includes a rotating plate that rotates to move the dust charged into the dust loading box so as to scrape it up, and a rotating plate that is scratched by the rotating plate. A push plate for moving the raised dust to push it into the storage space is provided, and the rotating plate and the push plate are arranged in the front direction in which the dust is moved and extended in the width direction of the dust input box. At least one of the rotating plate and the push-in plate is provided with a front plate, and is passed to a pair of reinforcing members having a reinforcing plate fixed to the back side of the front plate and extended in the width direction, and the reinforcing plates. The rear plate is provided with a rear plate that is fixed and extended in the width direction, and the rear plate is provided with a bent portion that is bent over the width direction between the reinforcing plates, and an end portion on the reinforcing member side is provided. It is characterized in that at least one of the pair of reinforcing members is overlapped with the back surface of the reinforcing plate in a parallel state and welded to the reinforcing plate.

上記構成を備えた、本発明の塵芥収集車における積込装置では、後プレートにおける補強部材側の端部を、補強部材の補強プレートの背面に平行な状態で重ねて補強プレートに溶接したことで、塵芥の移動による反力としての負荷が積込装置に働き、回転板あるいは押込板の前プレートとともにこれに固定されている補強部材が撓むように変形した際でも、後プレートと補強プレートとの溶接部分に応力が集中せず、しかも後プレートは、補強プレートの間にあって幅方向に亘って折曲した折曲部を有しているから、補強部材の撓みに応じた後プレートにおける撓みが折曲部の変形として吸収されて、その分だけ溶接部分に働く負荷を軽減させられる。 In the loading device in the dust collecting vehicle of the present invention having the above configuration, the end portion of the rear plate on the reinforcing member side is overlapped in a state parallel to the back surface of the reinforcing plate of the reinforcing member and welded to the reinforcing plate. , Even when the load as a reaction force due to the movement of dust acts on the loading device and the reinforcing member fixed to the front plate of the rotating plate or the pushing plate is deformed so as to bend, the rear plate and the reinforcing plate are welded together. Since the stress is not concentrated on the portion and the rear plate has a bent portion that is bent in the width direction between the reinforcing plates, the bending of the rear plate according to the bending of the reinforcing member is bent. It is absorbed as deformation of the part, and the load acting on the welded part can be reduced accordingly.

本発明の塵芥収集車では、前記補強部材は、前記前プレートの背面に立上げられるよう基端を固定されたフランジを備え、前記補強プレートは前記フランジの先端に一体的に形成されて該補強プレートとフランジの連続部分が角部とされており、前記折曲部は前記角部に対応する部位に形成された構成を採用できる。 In the dust collecting vehicle of the present invention, the reinforcing member includes a flange whose base end is fixed so as to be raised on the back surface of the front plate, and the reinforcing plate is integrally formed at the tip of the flange to reinforce the reinforcement. The continuous portion between the plate and the flange is a corner portion, and the bent portion can adopt a configuration formed at a portion corresponding to the corner portion.

上記構成の塵芥収集車において、積込装置に、塵芥の移動による反力としての負荷が働き、回転板あるいは押込板の前プレートとともにこれを補強している補強部材が撓むように変形した際でも、後プレートでは折曲部が角部に対応する部位に形成されていることで、折曲部は、後プレートと補強プレートとの溶接部の近傍において変形して、溶接部に働く負荷が抑えられる。 In the dust collecting vehicle having the above configuration, even when a load as a reaction force due to the movement of the dust acts on the loading device and the reinforcing member reinforcing the rotating plate or the front plate of the pushing plate is deformed so as to bend. Since the bent portion of the rear plate is formed at the portion corresponding to the corner portion, the bent portion is deformed in the vicinity of the welded portion between the rear plate and the reinforcing plate, and the load acting on the welded portion is suppressed. ..

本発明によれば、塵芥収集車の積込装置において、補強部材と後プレートの溶接部分の破損を防止し得る。 According to the present invention, it is possible to prevent damage to the welded portion between the reinforcing member and the rear plate in the loading device of the dust collecting vehicle.

以下、本発明の一実施形態に係る塵芥収集車を、図面を参照しつつ説明する。なお、以下の方向の特定において、前後方向とは塵芥収集車の前後方向であり、幅方向とは塵芥収集車を前方または後方から見た場合の左右方向である。 Hereinafter, the dust collecting vehicle according to the embodiment of the present invention will be described with reference to the drawings. In specifying the following directions, the front-rear direction is the front-rear direction of the dust collecting vehicle, and the width direction is the left-right direction when the dust collecting vehicle is viewed from the front or the rear.

図1に示すように、本実施形態における塵芥収集車1は、回転板式の塵芥収容方式を用いている。この塵芥収集車1は、車体1a上に搭載された塵芥収容箱2と、その後部に連接された塵芥投入箱3とを備えている。 As shown in FIG. 1, the dust collecting vehicle 1 in the present embodiment uses a rotating plate type dust collecting system. The dust collecting vehicle 1 includes a dust storage box 2 mounted on the vehicle body 1a and a dust charging box 3 connected to the rear portion thereof.

塵芥投入箱3の後部には、塵芥を投入するための投入口3aが形成されている。塵芥投入箱3の前方下部には、塵芥投入箱3に投入された塵芥を塵芥収容箱2の収容空間2Aに収容するために塵芥収容箱2から移す開口部3dが設けられている。 At the rear of the dust input box 3, an input port 3a for charging dust is formed. An opening 3d is provided in the lower front portion of the dust storage box 3 to move the dust charged into the dust storage box 3 from the dust storage box 2 in order to store the dust in the dust storage box 2 in the storage space 2A.

塵芥投入箱3には、投入口3aを開閉可能なカバー部材39が設けられている。このカバー部材39は、投入口3aの上部を開閉する上部カバー40と、投入口3aの下部を開閉する下部カバー41とを備えている。 The dust input box 3 is provided with a cover member 39 capable of opening and closing the input port 3a. The cover member 39 includes an upper cover 40 that opens and closes the upper part of the insertion port 3a, and a lower cover 41 that opens and closes the lower part of the insertion port 3a.

下部カバー41は、投入口3aの下部に回動可能に取付けられており、起立姿勢と水平姿勢(図1の破線位置)とに切替えることができる。この下部カバー41は、車幅方向のほぼ全長に亘って延長されている。下部カバー41の水平姿勢では、作業者が塵芥を投入口3aから投入する際に、下部カバー41に塵芥を一旦載置させることで、塵芥投入の作業性を高めることができる。 The lower cover 41 is rotatably attached to the lower part of the insertion port 3a, and can be switched between a standing posture and a horizontal posture (broken line position in FIG. 1). The lower cover 41 is extended over almost the entire length in the vehicle width direction. In the horizontal posture of the lower cover 41, when the operator throws the dust through the charging port 3a, the dust can be once placed on the lower cover 41 to improve the workability of the dust feeding.

塵芥投入箱3内には、塵芥収容箱2の収容空間2Aへ塵芥を移動させ積込装置が設けられている。積込装置は、塵芥投入箱3内で回転中心軸である下部支持軸54回りに回転する回転板52と、回転板52によって塵芥投入箱3内で掻上げられた塵芥を前方へ押すべく、揺動中心軸である上部支持軸55回りに前後方向に揺動する押込板53とを備える。 Inside the dust input box 3, a loading device is provided for moving the dust to the storage space 2A of the dust storage box 2. The loading device pushes forward the rotating plate 52 that rotates around the lower support shaft 54, which is the central axis of rotation in the dust loading box 3, and the dust that has been picked up in the dust loading box 3 by the rotating plate 52. A push plate 53 that swings in the front-rear direction around the upper support shaft 55, which is the swing center axis, is provided.

回転板52は、塵芥投入箱3に投入された塵芥を、塵芥投入箱3内に形成された円弧状の底部(「ホッパ」ともいう)3eから前方上部に掻上げるよう移動させる部材である。回転板52は、幅方向に延びる下部支持軸54と一体であり、下部支持軸54とともにその中心軸線回りに回転可能である。下部支持軸54(回転板52)は、図示しない油圧モータに減速機構を介して連結されている。下部支持軸54は油圧モータの駆動によって、360゜正逆転可能に回転駆動され、油圧モータの駆動により下部支持軸54が回転駆動することで、下部支持軸54と一体である回転板52が回転する。なお、図1において矢印で示す時計回り方向が回転板52の正転方向である。 The rotary plate 52 is a member that moves the dust thrown into the dust throwing box 3 so as to be scraped up from the arcuate bottom (also referred to as “hopper”) 3e formed in the dust throwing box 3 to the front upper part. The rotating plate 52 is integrated with the lower support shaft 54 extending in the width direction, and can rotate together with the lower support shaft 54 around its central axis. The lower support shaft 54 (rotary plate 52) is connected to a hydraulic motor (not shown) via a reduction mechanism. The lower support shaft 54 is rotationally driven so as to be able to rotate 360 ° forward and reverse by the drive of the hydraulic motor, and the lower support shaft 54 is rotationally driven by the drive of the hydraulic motor, so that the rotary plate 52 integrated with the lower support shaft 54 rotates. To do. The clockwise direction indicated by the arrow in FIG. 1 is the forward rotation direction of the rotating plate 52.

押込板53は、回転板52により掻上げられて回転板52上にある塵芥を、塵芥投入箱3の前方に連接する塵芥収容箱2内(収容空間2A)に移動させて押込むための部材である。押込板53は、幅方向に延びる上部支持軸55と一体であり、その軸線回りに、前方および後方揺動可能である。押込板53は、押込駆動手段として、幅方向に一対で設けられた押込シリンダ57の伸縮により、上部支持軸55回りに前方および後方揺動される。この押込シリンダ57は、塵芥投入箱3の左右両側に配置した側壁3cに対し、幅方向外側に配置されている。押込シリンダ57のシリンダ側端部は、ピン58により側壁3cの両側に取付けられており、ピストン側端部はピン59により、押込板53の上端部に接続されている。 The push-in plate 53 is a member for moving and pushing the dust on the rotary plate 52, which is scraped up by the rotary plate 52, into the dust storage box 2 (storage space 2A) connected to the front of the dust input box 3. .. The push plate 53 is integrated with the upper support shaft 55 extending in the width direction, and can swing forward and backward around the axis. The push plate 53 swings forward and backward around the upper support shaft 55 as a push drive means by expanding and contracting a pair of push cylinders 57 provided in the width direction. The push cylinder 57 is arranged outside in the width direction with respect to the side walls 3c arranged on both the left and right sides of the dust input box 3. The cylinder-side ends of the push-in cylinder 57 are attached to both sides of the side wall 3c by pins 58, and the piston-side ends are connected to the upper end of the push-in plate 53 by pins 59.

下部支持軸54および上部支持軸55は、塵芥投入箱3内を幅方向に延びるように互いに平行に配置され、その各軸の両端部が塵芥投入箱3の左右両側壁3cにそれぞれ軸受(図示せず)を介して回転自在に貫通支持されている。なお、下部支持軸54および上部支持軸55は、1本の軸であることは必須でなく、軸受に支持される部分が左右側に離間した2本の軸とすることができる。 The lower support shaft 54 and the upper support shaft 55 are arranged in parallel with each other so as to extend in the dust loading box 3 in the width direction, and both ends of the shafts are bearing on the left and right side walls 3c of the dust loading box 3, respectively (FIG. It is rotatably penetrated and supported via (not shown). The lower support shaft 54 and the upper support shaft 55 do not necessarily have one shaft, and the portion supported by the bearing may be two shafts separated from each other on the left and right sides.

図2(a)〜(d)は、回転板52、押込板53および押込シリンダ57のみを抜き出して示した動作説明図である。本実施形態では、矢印方向への円軌跡Rにて示す回転板52の回転動作と、両矢印方向への円弧軌跡Sにて示す押込板53の揺動動作により、塵芥投入箱3内に投入された塵芥が塵芥収容箱2に収容される。すなわち、回転板52は、図2(a)に示す回転板52が図示における略9時の位置を原位置として、油圧モータが駆動することにより時計回り方向に回転する「回転」工程を開始する。 2 (a) to 2 (d) are operation explanatory views showing only the rotating plate 52, the pushing plate 53, and the pushing cylinder 57 extracted. In the present embodiment, the rotating plate 52 is thrown into the dust input box 3 by the rotating operation of the rotating plate 52 indicated by the circular locus R in the direction of the arrow and the swinging operation of the pushing plate 53 indicated by the arc locus S in the direction of the double arrow. The collected dust is stored in the dust storage box 2. That is, the rotating plate 52 starts a "rotation" process in which the rotating plate 52 shown in FIG. 2A rotates clockwise when the hydraulic motor is driven with the position at about 9 o'clock in the drawing as the original position. ..

回転板52が図2(b)に示す略12時の位置(起立位置)に達すると、押込板53の先端部53aは押込シリンダ57の収縮動作により後方(矢印Sr方向)へ揺動する「後退」行程を行い、この先端部53aが図2(c)に示す位置(後退終了位置)まで後方揺動すると、押込板53の後方揺動が停止する。その際、回転板52は押込板53の後退中も継続して回転しているため、当該後退中に押込板53と回転板52との干渉が防止される。 When the rotating plate 52 reaches the position (standing position) at approximately 12 o'clock shown in FIG. 2B, the tip portion 53a of the pushing plate 53 swings backward (in the direction of arrow Sr) due to the contraction operation of the pushing cylinder 57. When the "backward" stroke is performed and the tip portion 53a swings backward to the position shown in FIG. 2C (backward end position), the backward swing of the push plate 53 stops. At that time, since the rotating plate 52 continues to rotate even while the pushing plate 53 is retracting, interference between the pressing plate 53 and the rotating plate 52 is prevented during the retracting.

その後、回転板52が回転を継続し、図2(d)に示す原位置(略9時の位置)に戻ると回転板52の回転が停止するとともに、押込シリンダ57が伸長動作することで、押込板53の先端部53aが前方(矢印Sf方向)へ揺動する「押込」行程を行う。押込板53の先端部53aが図2(a)に示す位置(押込終了位置P)まで前方揺動すると、押込板53の前方揺動が停止する。 After that, when the rotating plate 52 continues to rotate and returns to the original position (position at about 9 o'clock) shown in FIG. 2 (d), the rotation of the rotating plate 52 is stopped and the pushing cylinder 57 is extended. A "pushing" stroke is performed in which the tip end portion 53a of the pushing plate 53 swings forward (in the direction of arrow Sf). When the tip portion 53a of the push plate 53 swings forward to the position shown in FIG. 2A (push end position P), the forward swing of the push plate 53 stops.

このように油圧モータおよび押込シリンダ57が協働して動作することにより、回転板52の回転および押込板53の後退・押込による1サイクルの行程動作が行われる。換言すれば、回転・後退・押込による1サイクル工程とは、最初に回転板52が原位置から回転を開始し、その回転途中に押込板53が後退終了位置まで後退し、さらに回転板52が原位置に戻って回転停止した後に、押込板53が後退終了位置から押込終了位置Pまで押込を行う一連の動作である。この一連の動作中には、回転板52の回転動作および押込板53の後退・押込動作が協働することで、両者が干渉しない。 By operating the hydraulic motor and the push cylinder 57 in cooperation with each other in this way, a one-cycle stroke operation is performed by rotating the rotary plate 52 and retracting / pushing the push plate 53. In other words, in the one-cycle process of rotation, retreat, and pushing, the rotating plate 52 first starts rotating from the original position, the pushing plate 53 retreats to the retreating end position during the rotation, and the rotating plate 52 further retreats. This is a series of operations in which the push plate 53 pushes from the retracted end position to the pushed end position P after returning to the original position and stopping the rotation. During this series of operations, the rotating operation of the rotating plate 52 and the retreating / pushing operation of the pushing plate 53 cooperate with each other so that they do not interfere with each other.

下部支持軸54および上部支持軸55の近傍には、回転板52および押込板53の動作位置をそれぞれ電気的に検知する、第一近接スイッチないし第四近接スイッチ(60,61,62a,62b)が配置されている。第一近接スイッチ60および第二近接スイッチ61は、下部支持軸54回りの回転板52の動作位置を検知する。第三近接スイッチ62aおよび第四近接スイッチ62bは、押込板53の動作位置を検知する。 In the vicinity of the lower support shaft 54 and the upper support shaft 55, a first proximity switch or a fourth proximity switch (60, 61, 62a, 62b) that electrically detects the operating positions of the rotating plate 52 and the push plate 53, respectively. Is placed. The first proximity switch 60 and the second proximity switch 61 detect the operating position of the rotating plate 52 around the lower support shaft 54. The third proximity switch 62a and the fourth proximity switch 62b detect the operating position of the push plate 53.

第一近接スイッチ60は、回転板52が前記原位置(略9時の位置)から前記起立位置(略12時の位置)へ回転するまで、下部支持軸54に取付けられたドグ80を検知することにより、回転板52が前記原位置(略9時の位置)から起立位置(略12時の位置)までの位置にあることを検知する。 The first proximity switch 60 detects the dog 80 attached to the lower support shaft 54 until the rotating plate 52 rotates from the original position (position at about 9 o'clock) to the standing position (position at about 12 o'clock). As a result, it is detected that the rotating plate 52 is in a position from the original position (position at about 9 o'clock) to the standing position (position at about 12 o'clock).

ドグ80は、下部支持軸54の軸中心と略同心の扇形状に形成されており、第一近接スイッチ60は、回転板52の先端部52aが原位置から前記起立位置の時計回りにおける直前位置へ回転するまでドグ80を検知する。これにより第一近接スイッチ60は、前記原位置で検知状態に、前記起立位置で非検知状態となる。 The dog 80 is formed in a fan shape substantially concentric with the axis center of the lower support shaft 54, and the first proximity switch 60 is a position immediately before the tip portion 52a of the rotating plate 52 is clockwise from the original position to the standing position. The dog 80 is detected until it rotates to. As a result, the first proximity switch 60 is in the detection state at the original position and in the non-detection state at the upright position.

第二近接スイッチ61は、ドグ80を検知することにより、回転板52が略6時の位置にあることを検知する。第二近接スイッチ61は、回転板52が略6時の位置から前記原位置(略9時の位置)の直前位置へ回転するまでドグ80を検知する。これにより、第二近接スイッチ61は、前記原位置で非検知状態となる。 The second proximity switch 61 detects that the rotating plate 52 is in the position of about 6 o'clock by detecting the dog 80. The second proximity switch 61 detects the dog 80 until the rotating plate 52 rotates from the position at about 6 o'clock to the position immediately before the original position (position at about 9 o'clock). As a result, the second proximity switch 61 is in the non-detection state at the original position.

第三近接スイッチ62aは、上部支持軸55に取付けられたドグ55aを検知することにより、押込板53が前記後退終了位置(図2(c))に達したことを検知する。押込終了検知手段である第四近接スイッチ62bは、前記ドグ55aを検知することにより、押込板53が前記押込終了位置(図2(a))に達したことを検知する。前記第一近接スイッチないし第四近接スイッチのうち、第三近接スイッチ62aおよび第四近接スイッチ62bは、塵芥投入箱3の側壁3cの外側面に固定的に取付けられている。 The third proximity switch 62a detects that the push plate 53 has reached the retracted end position (FIG. 2C) by detecting the dog 55a attached to the upper support shaft 55. The fourth proximity switch 62b, which is the push-in end detecting means, detects that the push-in plate 53 has reached the push-in end position (FIG. 2A) by detecting the dog 55a. Of the first proximity switch to the fourth proximity switch, the third proximity switch 62a and the fourth proximity switch 62b are fixedly attached to the outer surface of the side wall 3c of the dust input box 3.

塵芥収集車1は、第一近接スイッチないし第四近接スイッチからの検知信号が入力される制御装置を備えている。制御装置は、車体1aの左舷下部に配置されている。制御装置は、第一近接スイッチないし第四近接スイッチからの検知信号に応じて、前述の1サイクル工程を行うよう、油圧モータ(回転板52)および押込シリンダ57(押込板53)の駆動を制御する。 The dust collecting vehicle 1 includes a control device to which a detection signal from the first proximity switch or the fourth proximity switch is input. The control device is arranged at the lower port side of the vehicle body 1a. The control device controls the drive of the hydraulic motor (rotary plate 52) and the push cylinder 57 (push plate 53) so as to perform the above-mentioned one-cycle process in response to the detection signal from the first proximity switch or the fourth proximity switch. To do.

上記構成を備えた塵芥収集車では、油圧モータの駆動に伴い下部支持軸54が減速されるよう回転するとともに、回転板52が下部支持軸54回りに回転し、下部支持軸54回りにおける回転板52の位置を、下部支持軸54とともに回転するドグ80の位置として、第一近接スイッチ60および第二近接スイッチ61が電気的に検出する。これにより、投入口3aから塵芥投入箱3内に投入され回転板52の回転により押上げられた塵芥を、押込板53が上部支持軸55回りに前方へ向けて揺動することで、塵芥収容箱2の収容空間2Aへ向けて押すよう、回転板52と押込板53とが干渉することなく協働して動作する。 In the dust collecting vehicle having the above configuration, the lower support shaft 54 rotates so as to be decelerated as the hydraulic motor is driven, and the rotating plate 52 rotates around the lower support shaft 54, so that the rotating plate around the lower support shaft 54 rotates. The first proximity switch 60 and the second proximity switch 61 electrically detect the position of 52 as the position of the dog 80 that rotates with the lower support shaft 54. As a result, the push-in plate 53 swings forward around the upper support shaft 55 to accommodate the dust that has been thrown into the dust-filling box 3 from the throw-in port 3a and pushed up by the rotation of the rotating plate 52. The rotating plate 52 and the pushing plate 53 operate in cooperation with each other so as to push toward the accommodation space 2A of the box 2.

ここで、回転板52、押込板53の構成を説明する。なお、回転板52、押込板53の単独の構成の説明において、前方とは塵芥を移動させる方向とする。背面とは、塵芥を移動させる方向と反対方向を向いた面のことである。はじめに回転板52について説明する。図3ないし図5に示すように、回転板52は、回転板用前プレート4、回転板用補強部材、および回転板用後プレート8を備える。回転板52は、これら回転板用前プレート4、回転板用補強部材、および回転板用後プレート8を幅方向両側で支持する回転板用支持部9,9を、さらに備える。 Here, the configurations of the rotating plate 52 and the pushing plate 53 will be described. In the description of the independent configuration of the rotating plate 52 and the pushing plate 53, the front is the direction in which the dust is moved. The back surface is a surface facing in the direction opposite to the direction in which the dust is moved. First, the rotating plate 52 will be described. As shown in FIGS. 3 to 5, the rotary plate 52 includes a rotary plate front plate 4, a rotary plate reinforcing member, and a rotary plate rear plate 8. The rotary plate 52 further includes a front plate 4 for the rotary plate, a reinforcing member for the rotary plate, and support portions 9 and 9 for the rotary plate that support the rear plate 8 for the rotary plate on both sides in the width direction.

As shown in FIGS. 4 and 5, the rotary plate front plate 4 has a plurality of bent portions extending in the width direction, and is formed in a curved shape as a whole so as to be convex toward the rear. With such a curved shape, when the rotating plate 52 rotates around the lower support shaft 54, it is easy to scrape up all the dust placed on the arcuate bottom portion 3e formed in the dust input box 3. ..

回転板用補強部材は、回転板用前プレート4の背面(裏面)に固定されている。回転板用補強部材は下部支持軸用ボス部12,12に近い方から回転板用第一補強部材5、回転板用第二補強部材6、回転板用第三補強部材7とされている。 The rotary plate reinforcing member is fixed to the back surface (back surface) of the rotary plate front plate 4. The reinforcing members for the rotating plate are the first reinforcing member 5 for the rotating plate, the second reinforcing member 6 for the rotating plate, and the third reinforcing member 7 for the rotating plate from the side closer to the lower support shaft boss portions 12 and 12.

便宜上、回転板用第二補強部材6の構成を説明する。回転板用第二補強部材6は、回転板用支持部9,9の間に亘って延長されている。回転板用第二補強部材6は、回転板用前プレート4の背面に、該背面から立上るように基端(前方側の端部)を固定された一対のフランジ6F,6Fと、このフランジ6F,6Fの先端(後方側の端部)にあって両フランジ6F,6F間に一体的に形成された回転板用第二補強プレート6Pとを備える。回転板用第二補強プレート6Pは平板状に形成されており、フランジ6F,6Fと回転板用第二補強プレート6Pとの連続部分は角部6Bとされている。 For convenience, the configuration of the second reinforcing member 6 for the rotating plate will be described. The second reinforcing member 6 for the rotary plate extends between the support portions 9 and 9 for the rotary plate. The second reinforcing member 6 for the rotating plate includes a pair of flanges 6F and 6F having a base end (front end) fixed to the back surface of the rotating plate front plate 4 so as to rise from the back surface, and the flanges. A second reinforcing plate 6P for a rotating plate, which is located at the tip (rear end) of the 6F and 6F and is integrally formed between the flanges 6F and 6F, is provided. The second reinforcing plate 6P for the rotating plate is formed in a flat plate shape, and the continuous portion between the flanges 6F and 6F and the second reinforcing plate 6P for the rotating plate is a corner portion 6B.

回転板用第三補強部材7は、回転板用第二補強部材6に離間して、回転板52の先端側に配置されており、回転板用前プレート4の背面に幅方向に亘って設けられている。回転板用第三補強部材7は、回転板用前プレート4の背面に、該背面から立上るように基端(前方側の端部)を固定された一対のフランジ7F,7Fと、このフランジ7F,7Fの先端(後方側の端部)にあって両フランジ7F,7F間に一体的に形成された回転板用第三補強プレート7Pとを備える。回転板用第三補強プレート7Pは平板状に形成されており、フランジ7F,7Fと回転板用第三補強プレート7Pとの連続部分は角部7Bとされている。 The third reinforcing member 7 for the rotary plate is arranged on the tip end side of the rotary plate 52 separated from the second reinforcing member 6 for the rotary plate, and is provided on the back surface of the front plate 4 for the rotary plate in the width direction. Has been done. The third reinforcing member 7 for a rotating plate includes a pair of flanges 7F and 7F having a base end (front end) fixed to the back surface of the rotating plate front plate 4 so as to rise from the back surface, and the flanges. It is provided with a third reinforcing plate 7P for a rotating plate, which is located at the tip of the 7F and 7F (the end on the rear side) and is integrally formed between the flanges 7F and 7F. The third reinforcing plate 7P for the rotating plate is formed in a flat plate shape, and the continuous portion between the flanges 7F and 7F and the third reinforcing plate 7P for the rotating plate is a corner portion 7B.

回転板用第一補強部材5は、回転板用支持部9,9の間に亘って延長されている。回転板用第一補強部材5は、回転板用第二補強部材6および回転板用第三補強部材7に比べて、回転板用前プレート4の背面の下部支持軸用ボス部12,12に近い側に配置されている。回転板用第一補強部材5は、回転板用前プレート4の背面に、該背面から立上るように基端(前方側の端部)を固定された一枚のフランジ5Fと、このフランジ5Fの先端(後方側の端部)にあってフランジ5Fの端部から回転板用第二補強プレート6Pに向けて折曲された回転板用第一補強プレート5Pとを備える。 The first reinforcing member 5 for the rotary plate extends between the support portions 9 and 9 for the rotary plate. The first reinforcing member 5 for the rotating plate has boss portions 12 and 12 for the lower support shaft on the back surface of the front plate 4 for the rotating plate, as compared with the second reinforcing member 6 for the rotating plate and the third reinforcing member 7 for the rotating plate. It is located on the near side. The first reinforcing member 5 for the rotating plate is a single flange 5F having a base end (front end) fixed to the back surface of the front plate 4 for the rotating plate so as to rise from the back surface, and the flange 5F. The first reinforcing plate 5P for a rotating plate is provided at the tip (rear end) of the flange 5F and bent toward the second reinforcing plate 6P for the rotating plate.

回転板用第一補強プレート5P、回転板用第二補強プレート6P、および回転板用第三補強プレート7Pは何れも平板状に形成されている。回転板用第二補強部材6における回転板用第二補強プレート6Pとフランジ6F,6Fとの連続部分、および回転板用第三補強部材7における回転板用第三補強プレート7Pとフランジ7F,7Fとの連続部分は何れも折曲されて形成された角部6B,7Bである。回転板用第二補強プレート6P、および回転板用第三補強プレート7Pは互いに平行ではなく、例えば、垂直方向に対する傾斜角度が異なる。 The first reinforcing plate 5P for the rotating plate, the second reinforcing plate 6P for the rotating plate, and the third reinforcing plate 7P for the rotating plate are all formed in a flat plate shape. The continuous portion between the second reinforcing plate 6P for the rotating plate and the flanges 6F, 6F in the second reinforcing member 6 for the rotating plate, and the third reinforcing plate 7P and the flanges 7F, 7F for the rotating plate in the third reinforcing member 7 for the rotating plate. The continuous portions with and are the corner portions 6B and 7B formed by bending. The second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate are not parallel to each other, and for example, the inclination angles with respect to the vertical direction are different.

回転板用第一補強部材5において、フランジ5Fと回転板用第一補強プレート5Pとの連続部分は、折曲された曲板部5Bである。この曲板部5Bが形成されていることにより、回転板用第一補強プレート5Pと回転板用第二補強プレート6Pとは平行に形成されている。回転板用第一補強プレート5Pの先端側は、回転板用第二補強プレート6Pの回転板用第一補強プレート5P側の一部の表面(背面)に、その幅方向に亘って重なる重合部5Sである。この重合部5Sは、回転板用第二補強プレート6Pの幅方向に亘ってその表面に溶接により固定されている。回転板用第一補強部材5の回転板用第一補強プレート5Pにおいて、その曲板部5Bは、回転板用第二補強プレート6Pから離間して、下部支持軸用ボス部12,12の近傍に配置されている。重合部5Sにおいて、溶接されている先端とは、曲板部5Bを含まず、曲板部5Bよりも先端側の領域部分である。 In the rotating plate first reinforcing member 5, the continuous portion between the flange 5F and the rotating plate first reinforcing plate 5P is a bent plate portion 5B. Since the curved plate portion 5B is formed, the first reinforcing plate 5P for the rotating plate and the second reinforcing plate 6P for the rotating plate are formed in parallel. The tip side of the first reinforcing plate 5P for the rotating plate is a superposed portion that overlaps a part of the surface (back surface) of the second reinforcing plate 6P for the rotating plate on the first reinforcing plate 5P side for the rotating plate over the width direction. It is 5S. The overlapping portion 5S is fixed to the surface of the second reinforcing plate 6P for a rotating plate by welding over the width direction. In the rotary plate first reinforcing plate 5P of the rotary plate first reinforcing member 5, the curved plate portion 5B is separated from the rotary plate second reinforcing plate 6P and is in the vicinity of the lower support shaft boss portions 12 and 12. Is located in. In the polymerization portion 5S, the welded tip does not include the curved plate portion 5B and is a region portion on the tip side of the curved plate portion 5B.

回転板用後プレート8は、離間して配置されている回転板用第二補強部材6および回転板用第三補強部材7の間に塵芥が侵入することを阻止する部材である。回転板用後プレート8は、互いに離間した回転板用第二補強プレート6Pおよび回転板用第三補強プレート7Pに渡すよう設けられている。 The rotary plate rear plate 8 is a member that prevents dust from entering between the rotary plate second reinforcing member 6 and the rotary plate third reinforcing member 7 that are arranged apart from each other. The rotary plate rear plate 8 is provided so as to pass to the rotary plate second reinforcing plate 6P and the rotary plate third reinforcing plate 7P which are separated from each other.

回転板用後プレート8は、塵芥投入箱3の幅方向に亘る板状部材である。回転板用後プレート8は、回転板用第二補強プレート6Pおよび回転板用第三補強プレート7Pの表面(背面)に、塵芥投入箱3の幅方向に亘って重ねられる重合部8S,8Sと、両重合部8S,8Sの間の架渡部8Hとを一体的に備えている。重合部8S,8Sは回転板用第三補強プレート7Pの表面と接触している。架渡部8Hは、回転板用第三補強プレート7Pとの接し終わりから回転板用第二補強プレート6Pまでの間の領域である。 The rear plate 8 for the rotating plate is a plate-shaped member extending in the width direction of the dust input box 3. The rear plate 8 for the rotating plate is formed by overlapping the overlapping portions 8S and 8S over the surface (back surface) of the second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate in the width direction of the dust input box 3. , A bridge portion 8H between both polymerization portions 8S and 8S is integrally provided. The overlapping portions 8S and 8S are in contact with the surface of the third reinforcing plate 7P for the rotating plate. The overhanging portion 8H is a region from the end of contact with the third reinforcing plate 7P for the rotating plate to the second reinforcing plate 6P for the rotating plate.

ここで、前述したように、回転板用第二補強プレート6P、および回転板用第三補強プレート7Pは互いに平行ではなく、例えば、垂直方向に対する傾斜角度が異なる。しかしながら、回転板用後プレート8における架渡部8H(回転板用第二補強プレート6Pと回転板用第三補強プレート7Pとの間)に、折曲された折曲部8B,8Bが形成され、この折曲部8B,8Bは、回転板用第二補強部材6、および回転板用第三補強部材7における角部6B,7Bに対応する部位に形成されている。折曲部8B,8Bは、回転板用第二補強部材6、および回転板用第三補強部材7の表面の、後方への延長線から重合部8S,8Sまでの間の領域とされている。すなわち、角部6B,7Bに対応する前記部位とは、角部6B,7Bを後方に投影させた領域内のことである。この折曲部8B,8Bが形成されていることにより、一方の重合部8Sと回転板用第二補強プレート6Pの表面(背面)とが平行とされ、他方の重合部8Sと回転板用第三補強プレート7Pの表面(背面)とが平行とされている。 Here, as described above, the second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate are not parallel to each other, and for example, the inclination angles with respect to the vertical direction are different. However, the bent portions 8B and 8B are formed on the crossing portion 8H (between the second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate) in the rear plate 8 for the rotating plate. The bent portions 8B and 8B are formed at portions corresponding to the corner portions 6B and 7B of the second reinforcing member 6 for the rotating plate and the third reinforcing member 7 for the rotating plate. The bent portions 8B and 8B are regions between the rear extension lines of the surfaces of the second reinforcing member 6 for the rotating plate and the third reinforcing member 7 for the rotating plate and the overlapping portions 8S and 8S. .. That is, the portion corresponding to the corner portions 6B and 7B is in the region where the corner portions 6B and 7B are projected rearward. By forming the bent portions 8B and 8B, one of the overlapping portions 8S and the surface (back surface) of the second reinforcing plate 6P for the rotating plate are made parallel to each other, and the other overlapping portion 8S and the second reinforcing plate for the rotating plate 6P are parallel to each other. The front surface (back surface) of the three reinforcing plates 7P is parallel to each other.

これら重合部8S,8Sの先端は、その幅方向に亘って回転板用第二補強プレート6P、回転板用第三補強プレート7Pの表面に溶接により固定されている。なお、折曲部8Bは、後方へ向けて凸となるよう折曲されている。つまり、両プレートが平行に重なり合っていることで、前プレートが撓んで補強プレートが動くときに、重なり合ったまま動き、両プレートの相対位置が変わらないので、溶接部にかかる負荷を抑制でき、溶接部の破損を防止できる。 The tips of the overlapping portions 8S and 8S are fixed to the surfaces of the second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate by welding over the width direction thereof. The bent portion 8B is bent so as to be convex toward the rear. In other words, because both plates overlap in parallel, when the front plate bends and the reinforcing plate moves, it moves while overlapping, and the relative positions of both plates do not change, so the load on the weld can be suppressed and welding can be performed. It is possible to prevent damage to the part.

上記構成の積込装置において、回転板52の正転方向への回転により、塵芥投入箱3内に形成された円弧状の底部3eから、塵芥を前方上部に掻上げるよう移動させると、回転板52に対し塵芥の重さに応じた反力が負荷として働く。塵芥による負荷が大きいと、回転板用前プレート4が下部支持軸54を中心として後方へ撓むよう変形することが考えられる。 In the loading device having the above configuration, when the rotating plate 52 is rotated in the forward rotation direction to move the dust from the arcuate bottom portion 3e formed in the dust input box 3 so as to scrape the dust toward the front upper part, the rotating plate A reaction force corresponding to the weight of the dust acts as a load on the 52. When the load due to the dust is large, it is conceivable that the front plate 4 for the rotating plate is deformed so as to bend backward about the lower support shaft 54.

そうなると、回転板用前プレート4に一体化されている回転板用第一補強部材5ないし回転板用第三補強部材7が、回転板用前プレート4の変形に応じて変形する。しかしながら、これら回転板用第一補強部材5ないし回転板用第三補強部材7の剛性により、回転板52の過度の変形が抑制される。 Then, the first reinforcing member 5 for the rotating plate or the third reinforcing member 7 for the rotating plate, which is integrated with the front plate 4 for the rotating plate, is deformed according to the deformation of the front plate 4 for the rotating plate. However, due to the rigidity of the first reinforcing member 5 for the rotating plate and the third reinforcing member 7 for the rotating plate, excessive deformation of the rotating plate 52 is suppressed.

ところで、回転板用第二補強プレート6Pおよび回転板用第三補強プレート7Pには回転板用後プレート8が渡され、回転板用後プレート8は折曲部8B,8Bを形成して、重合部8S,8Sの先端が回転板用第二補強プレート6Pおよび回転板用第三補強プレート7Pに溶接されている。 By the way, the rear plate 8 for the rotating plate is passed to the second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate, and the rear plate 8 for the rotating plate forms bent portions 8B and 8B and overlaps with each other. The tips of the portions 8S and 8S are welded to the second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate.

この構成の回転板52において、塵芥による反力が負荷として回転板用前プレート4に働くことで、回転板用第二補強部材6および回転板用第三補強部材7が変形して回転板用第二補強プレート6Pおよび回転板用第三補強プレート7Pが変形すれば、その変形に応じて回転板用後プレート8も変形する。しかしながら、回転板用後プレート8には折曲部8B,8Bが形成されている。このため、回転板用後プレート8の撓み(撓み量)は、折曲部8B,8Bの変形として吸収される。回転板用後プレート8においては、折曲部8B,8Bが変形することにより、その分だけ重合部8S,8Sにおける溶接部分に働く負荷が抑えられ、溶接部分の破損が防止できる。 In the rotary plate 52 having this configuration, the reaction force generated by dust acts on the rotary plate front plate 4 as a load, so that the rotary plate second reinforcing member 6 and the rotary plate third reinforcing member 7 are deformed for the rotary plate. If the second reinforcing plate 6P and the third reinforcing plate 7P for the rotating plate are deformed, the rear plate 8 for the rotating plate is also deformed according to the deformation. However, the bent portions 8B and 8B are formed on the rear plate 8 for the rotating plate. Therefore, the bending (deflection amount) of the rear plate 8 for the rotating plate is absorbed as the deformation of the bent portions 8B and 8B. In the rear plate 8 for the rotating plate, since the bent portions 8B and 8B are deformed, the load acting on the welded portions in the polymerized portions 8S and 8S can be suppressed by that amount, and the welded portions can be prevented from being damaged.

そして、回転板用後プレート8の重合部8S,8Sの先端は、回転板用第二補強プレート6Pおよび回転板用第三補強プレート7Pの表面に平行な状態で重ねられて溶接され、折曲部8B,8Bは回転板用第二補強部材6および回転板用第三補強部材7の角部6B,7Bに対応する部分に形成されている。この構成によれば、回転板用後プレート8の折曲部8B,8Bは、一方の重合部8Sと回転板用第二補強プレート6Pとの溶接部分、他方の重合部8Sと回転板用第三補強プレート7Pとの溶接部分の近傍において変形して、折曲部8B,8Bよりも先端側の変形が抑えられる。このため、溶接部分に働く負荷が抑えられ、いっそう確実に溶接部分の破損が防止できる。 Then, the tips of the overlapping portions 8S and 8S of the rear plate 8 for the rotating plate are overlapped and welded in parallel with the surfaces of the second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate, and are bent. The portions 8B and 8B are formed in portions corresponding to the corner portions 6B and 7B of the second reinforcing member 6 for the rotating plate and the third reinforcing member 7 for the rotating plate. According to this configuration, the bent portions 8B and 8B of the rear plate 8 for the rotating plate are welded portions of one overlapping portion 8S and the second reinforcing plate 6P for the rotating plate, and the other overlapping portion 8S and the second reinforcing plate for the rotating plate. (3) Deformation occurs in the vicinity of the welded portion with the reinforcing plate 7P, and deformation on the tip side of the bent portions 8B and 8B is suppressed. Therefore, the load acting on the welded portion is suppressed, and damage to the welded portion can be prevented more reliably.

溶接部分の破損が防止できれば、回転板用第二補強部材6、回転板用第三補強部材7の間への塵芥の侵入が防止できる。また、回転板用第二補強プレート6P、および回転板用第三補強プレート7Pは互いに平行ではなく傾斜角度が異なる。しかしながら、回転板用後プレート8に折曲部8B,8Bを形成したことにより、重合部8S,8Sを回転板用第二補強プレート6P、および回転板用第三補強プレート7Pに平行な状態で重ねることができ、これにより重合部8S,8Sでの溶接作業が容易になる。 If the welded portion can be prevented from being damaged, it is possible to prevent dust from entering between the second reinforcing member 6 for the rotating plate and the third reinforcing member 7 for the rotating plate. Further, the second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate are not parallel to each other and have different inclination angles. However, by forming the bent portions 8B and 8B on the rear plate 8 for the rotating plate, the overlapping portions 8S and 8S are parallel to the second reinforcing plate 6P for the rotating plate and the third reinforcing plate 7P for the rotating plate. It can be stacked, which facilitates the welding work in the overlapping sections 8S and 8S.

次に、押込板53の構成を説明する。図6ないし図8に示すように、押込板53は、押込板用前プレート13、押込板用補強部材、および押込板用後プレート17を備える。押込板53は、これら押込板用前プレート13、押込板用補強部材、および押込板用後プレート17を幅方向両側で支持する押込板用支持部18,18を、さらに備える。 Next, the configuration of the push-in plate 53 will be described. As shown in FIGS. 6 to 8, the push plate 53 includes a push plate front plate 13, a push plate reinforcing member, and a push plate rear plate 17. The push plate 53 further includes a front plate 13 for the push plate, a reinforcing member for the push plate, and support portions 18 and 18 for the push plate that support the rear plate 17 for the push plate on both sides in the width direction.

押込板用支持部18,18は、押込板53において幅方向両側に配置されており、それぞれ幅方向に離間して平行に配置された一対の押込板用支持プレート19,19を備える。この押込板用支持プレート19,19は、側壁3cに平行に配置されている。押込板用支持プレート19,19どうしの後部に、押込板用連結プレート20が渡されて、各押込板用支持部18,18の押込板用支持プレート19,19どうしが押込板用連結プレート20を介して固定されている。押込板用支持部18,18の一方側寄り位置に、上部支持軸55の各端部側を挿通支持する上部支持軸用ボス部21,21が一体的に挿通支持される。 The push plate support portions 18 and 18 are arranged on both sides in the width direction of the push plate 53, and include a pair of push plate support plates 19 and 19 arranged in parallel with each other separated in the width direction. The push plate support plates 19 and 19 are arranged in parallel with the side wall 3c. The push plate connecting plates 20 are passed to the rear portions of the push plate support plates 19 and 19, and the push plate support plates 19 and 19 of the push plate support portions 18 and 18 are connected to each other. It is fixed via. The upper support shaft boss portions 21 and 21 that insert and support each end side of the upper support shaft 55 are integrally inserted and supported at positions closer to one side of the push plate support portions 18 and 18.

押込板用前プレート13は、押込板用支持部18,18(押込板用支持プレート19,19)の前側端面に渡すように押込板用支持部18,18に固定され、塵芥投入箱3の幅方向に延長されて略幅方向全長に亘る。図7および図8に示すように、押込板用前プレート13は幅方向に亘る複数箇所の屈曲部を有して、全体として前方へ向けて凸となるよう構成されている。このような形状とすることにより、押込板53が上部支持軸55回りに回転した際に、塵芥を押し易い。 The push plate front plate 13 is fixed to the push plate support portions 18 and 18 so as to pass over the front end faces of the push plate support portions 18 and 18 (push plate support plates 19 and 19), and is fixed to the push plate support portions 18 and 18 of the dust input box 3. It is extended in the width direction and extends over the entire length in the width direction. As shown in FIGS. 7 and 8, the push plate front plate 13 has a plurality of bent portions extending in the width direction, and is configured to be convex toward the front as a whole. With such a shape, when the push plate 53 rotates around the upper support shaft 55, it is easy to push the dust.

押込板用補強部材は、押込板用前プレート13の背面(裏面)に固定されている。押込板用補強部材は、上部支持軸用ボス部21,21の前側に配置された押込板用第一補強部材14および押込板用第二補強部材15と、押込板用前プレート13の下寄り位置に配置された押込板用第三補強部材16とされる。 The push plate reinforcing member is fixed to the back surface (back surface) of the push plate front plate 13. The push plate reinforcing members are the push plate first reinforcing member 14 and the push plate second reinforcing member 15 arranged on the front side of the upper support shaft boss portions 21 and 21, and the push plate front plate 13 below. It is a third reinforcing member 16 for a push plate arranged at a position.

押込板用第一補強部材14の構成を説明する。押込板用第一補強部材14は、押込板用支持部18,18の間に亘って延長されている。押込板用第一補強部材14は、押込板用前プレート13の背面に、該背面から立上るように基端(前方側の端部)を固定された一対のフランジ14F,14Fと、フランジ14F,14Fの先端(後方側の端部)にあって両フランジ14F,14Fの間に一体的に形成された押込板用第一補強プレート14Pとを備える。押込板用第一補強プレート14Pは平板状に形成されており、フランジ14F,14Fと押込板用第一補強プレート14Pとの連続部分は角部141Bとされている。 The configuration of the first reinforcing member 14 for the push plate will be described. The first reinforcing member 14 for the push plate extends between the support portions 18 and 18 for the push plate. The first reinforcing member 14 for the push plate is a pair of flanges 14F and 14F having a base end (front end) fixed to the back surface of the front plate 13 for the push plate so as to rise from the back surface, and a flange 14F. , 14P is provided with a first reinforcing plate 14P for a push plate, which is located at the tip (rear end) of 14F and is integrally formed between both flanges 14F and 14F. The first reinforcing plate 14P for the push plate is formed in a flat plate shape, and the continuous portion between the flanges 14F and 14F and the first reinforcing plate 14P for the push plate is a corner portion 141B.

押込板用第二補強部材15は、押込板用前プレート13の背面に、該背面から立上るように基端(前方側の端部)を固定された一個のフランジ15Fと、フランジ15Fの先端(後方側の端部)にあってフランジ15Fに一体的に形成された押込板用第二補強プレート15Pとを備える。押込板用第二補強プレート15Pは平板状に形成されており、フランジ15Fと押込板用第二補強プレート15Pとの連続部分は角部15Bとされている。 The second reinforcing member 15 for the push plate has one flange 15F having a base end (front end) fixed to the back surface of the front plate 13 for the push plate so as to rise from the back surface, and the tip of the flange 15F. It is provided with a second reinforcing plate 15P for a push plate, which is located (at the end on the rear side) and is integrally formed with the flange 15F. The second reinforcing plate 15P for the push plate is formed in a flat plate shape, and the continuous portion between the flange 15F and the second reinforcing plate 15P for the push plate is a corner portion 15B.

押込板用第二補強プレート15Pは、押込板用第一補強プレート14Pと平行に形成され、且つ押込板用第一補強プレート14Pに平行な状態で重なる重合部15Sを有する。重合部15Sは、その幅方向に亘って押込板用第一補強プレート14Pの表面(背面)に接触している。この重合部15Sの先端は、押込板用第一補強プレート14Pに溶接されている。 The second reinforcing plate 15P for the push plate has a superposed portion 15S formed in parallel with the first reinforcing plate 14P for the push plate and overlapping in a state parallel to the first reinforcing plate 14P for the push plate. The polymerization portion 15S is in contact with the surface (back surface) of the first reinforcing plate 14P for the push plate over the width direction thereof. The tip of the polymerization portion 15S is welded to the first reinforcing plate 14P for the pressing plate.

押込板用第三補強部材16は、押込板用第二補強部材15に離間して、押込板53の先端側に配置されており、押込板用前プレート13の背面に幅方向に亘って設けられている。押込板用第三補強部材16は、押込板用前プレート13の背面に、該背面から立上るように基端(前方側の端部)を固定された一対のフランジ16F,16Fと、フランジ16F,16Fの先端(後方側の端部)にあって両フランジ16F,16Fの間に一体的に形成された押込板用第三補強プレート16Pとを備える。押込板用第三補強プレート16Pは平板状に形成されており、フランジ16F,16Fと押込板用第三補強プレート16Pとの連続部分は角部16Bとされている。 The third reinforcing member 16 for the push plate is arranged on the tip end side of the push plate 53 separated from the second reinforcing member 15 for the push plate, and is provided on the back surface of the front plate 13 for the push plate in the width direction. Has been done. The third reinforcing member 16 for the push plate includes a pair of flanges 16F and 16F and flanges 16F having base ends (front ends) fixed to the back surface of the front plate 13 for the push plate so as to rise from the back surface. , A third reinforcing plate 16P for a push plate, which is located at the tip of 16F (the end on the rear side) and is integrally formed between both flanges 16F and 16F. The third reinforcing plate 16P for the push plate is formed in a flat plate shape, and the continuous portion between the flanges 16F and 16F and the third reinforcing plate 16P for the push plate is a corner portion 16B.

押込板用第二補強プレート15P、および押込板用第三補強プレート16Pは互いに平行ではなく、例えば、垂直方向に対する傾斜角度が異なる。具体的に、押込板用第二補強プレート15Pは上下方向に沿い、押込板用第三補強プレート16Pは下方側が前方に向けて傾斜するよう形成されている。 The second reinforcing plate 15P for the push plate and the third reinforcing plate 16P for the push plate are not parallel to each other, and for example, the inclination angles with respect to the vertical direction are different. Specifically, the second reinforcing plate 15P for the push plate is formed along the vertical direction, and the third reinforcing plate 16P for the push plate is formed so that the lower side is inclined toward the front.

押込板用後プレート17は、押込板用第二補強プレート15Pおよび押込板用第三補強プレート16Pに亘るように設けられている。また、押込板用後プレート17は、離間して配置されている押込板用第二補強部材15および押込板用第三補強部材16の間に塵芥が侵入することを阻止する部材である。 The rear plate 17 for the push plate is provided so as to extend over the second reinforcing plate 15P for the push plate and the third reinforcing plate 16P for the push plate. Further, the push plate rear plate 17 is a member that prevents dust from entering between the push plate second reinforcing member 15 and the push plate third reinforcing member 16 that are arranged apart from each other.

押込板用後プレート17は、押込板用第二補強部材15の幅方向に亘る板状部材である。押込板用後プレート17は、押込板用第二補強プレート15Pおよび押込板用第三補強プレート16Pの表面に、押込板用第二補強プレート15Pの幅方向に亘って重ねられる重合部17S,17Sと、重合部17S,17Sの間の架渡部17H(押込板用第二補強プレート15Pと押込板用第三補強プレート16Pとの間)とを一体的に備えている。重合部17S,17Sのうち、押込板用第三補強プレート16P側の重合部17S付近の架渡部17Hに折曲部17Bが形成されている。 The rear plate 17 for the push plate is a plate-shaped member extending in the width direction of the second reinforcing member 15 for the push plate. The rear plate 17 for the push plate is laminated on the surfaces of the second reinforcing plate 15P for the push plate and the third reinforcing plate 16P for the push plate over the width direction of the second reinforcing plate 15P for the push plate. And a bridge portion 17H (between the second reinforcing plate 15P for the pushing plate and the third reinforcing plate 16P for the pushing plate) between the overlapping portions 17S and 17S are integrally provided. Of the polymerized portions 17S and 17S, the bent portion 17B is formed in the overhanging portion 17H near the polymerized portion 17S on the third reinforcing plate 16P side for the push plate.

ここで、前述したように、押込板用第二補強プレート15P、および押込板用第三補強プレート16Pは互いに平行ではなく傾斜角度が異なる。しかしながら、押込板用後プレート17における架渡部17H(押込板用第二補強プレート15Pと押込板用第三補強プレート16Pの間)に折曲された折曲部17Bが形成され、折曲部17Bは押込板用第三補強部材16における角部16Bに対応する部位に形成されている。この対応する部位とは、回転板52で説明したのと同様に、角部16Bを後方に投影させた領域内のことであるから詳しい説明を繰返さない。この折曲部17Bが形成されていることにより、一方の重合部17Sと押込板用第三補強プレート16Pの表面(背面)とが平行とされている。 Here, as described above, the second reinforcing plate 15P for the push plate and the third reinforcing plate 16P for the push plate are not parallel to each other and have different inclination angles. However, a bent portion 17B is formed in the bridge portion 17H (between the second reinforcing plate 15P for the pushing plate and the third reinforcing plate 16P for the pushing plate) in the rear plate 17 for the pushing plate, and the bent portion 17B is formed. Is formed at a portion corresponding to the corner portion 16B of the third reinforcing member 16 for the push plate. Since the corresponding portion is in the region where the corner portion 16B is projected rearward, as described with the rotating plate 52, detailed description will not be repeated. Since the bent portion 17B is formed, one of the overlapping portions 17S and the surface (back surface) of the third reinforcing plate 16P for the pressing plate are parallel to each other.

重合部17S,17Sの先端は、それぞれ押込板用第二補強プレート15P、押込板用第三補強プレート16Pに溶接されて固定されている。なお、折曲部17Bは後方へ向けて凸となるよう折曲されている。つまり、両プレートが平行に重なり合っていることで、前プレートが撓んで補強プレートが動くときに、重なり合ったまま動き、両プレートの相対位置が変わらないので、溶接部にかかる負荷を抑制でき、溶接部の破損を防止できる。 The tips of the overlapping portions 17S and 17S are welded and fixed to the second reinforcing plate 15P for the pressing plate and the third reinforcing plate 16P for the pressing plate, respectively. The bent portion 17B is bent so as to be convex toward the rear. In other words, because both plates overlap in parallel, when the front plate bends and the reinforcing plate moves, it moves while overlapping, and the relative positions of both plates do not change, so the load on the weld can be suppressed and welding can be performed. It is possible to prevent damage to the part.

ところで、回転板52は、塵芥を掻上げて押込板53で塵芥収容箱2内に塵芥を押すとき、回転板52の回転板用前プレート4と、押込板53の先端との隙間をできるだけ小さくして塵芥の掻込みを抑制するために、回転板用前プレート4は、上部支持軸55回りの、押込板53の先端の軌跡に沿うよう湾曲させている。このため、回転板用前プレート4の背面に設けられる補強部材における補強プレートは、補強部材を設ける位置により角度を異ならせている。 By the way, when the rotary plate 52 picks up the dust and pushes the dust into the dust storage box 2 by the push plate 53, the gap between the rotary plate front plate 4 of the rotary plate 52 and the tip of the push plate 53 is made as small as possible. In order to suppress the entrainment of dust, the rotary plate front plate 4 is curved so as to follow the trajectory of the tip of the push plate 53 around the upper support shaft 55. Therefore, the angle of the reinforcing plate in the reinforcing member provided on the back surface of the rotary plate front plate 4 is different depending on the position where the reinforcing member is provided.

一方で、押込板53においては、上部支持軸55回りに回転する動作により塵芥を押し易くするために、押込板用前プレート13は前述したように、複数箇所において屈曲させている。このため、押込板用前プレート13の背面に設けられる補強部材における補強プレートは、補強部材を設ける位置により角度を異ならせている。そして、押込板53は、全体として塵芥投入箱3を幅方向(側方)から見て、揺動中心軸である上部支持軸55回りのモーメントの少ない先端ほど先細る形状に形成されており、先細りとしたスペース内に補強部材が納められた構成となっている。 On the other hand, in the push plate 53, the push plate front plate 13 is bent at a plurality of places as described above in order to facilitate pushing the dust by the operation of rotating around the upper support shaft 55. Therefore, the angle of the reinforcing plate in the reinforcing member provided on the back surface of the push plate front plate 13 is different depending on the position where the reinforcing member is provided. As a whole, the push-in plate 53 is formed so that the tip of the dust input box 3 with less moment around the upper support shaft 55, which is the swing center axis, is tapered when viewed from the width direction (side). Reinforcing members are housed in a tapered space.

上記構成の積込装置において、押込板53が上部支持軸55回りに前方に移動することにより、回転板52により掻上げられた塵芥が前方へ押される。この際、押込板53に対し塵芥の重さに応じた反力が負荷として働く。塵芥による負荷が大きいと、押込板用前プレート13が上部支持軸55を中心として後方へ撓むよう変形することが考えられる。 In the loading device having the above configuration, the pushing plate 53 moves forward around the upper support shaft 55, so that the dust scraped up by the rotating plate 52 is pushed forward. At this time, a reaction force corresponding to the weight of the dust acts as a load on the pushing plate 53. When the load due to the dust is large, it is conceivable that the push plate front plate 13 is deformed so as to bend backward about the upper support shaft 55.

そうなると、押込板用前プレート13に一体化されている押込板用第一補強部材14ないし押込板用第三補強部材16が、押込板用前プレート13の変形に応じて変形する。しかしながら、これら押込板用第一補強部材14ないし押込板用第三補強部材16の剛性により、押込板53の過度の変形が抑制される。 Then, the push plate first reinforcing member 14 or the push plate third reinforcing member 16 integrated with the push plate front plate 13 is deformed according to the deformation of the push plate front plate 13. However, due to the rigidity of the first reinforcing member 14 for the push plate or the third reinforcing member 16 for the push plate, excessive deformation of the push plate 53 is suppressed.

ところで、押込板用第二補強プレート15Pおよび押込板用第三補強プレート16Pには押込板用後プレート17が渡され、押込板用後プレート17は折曲部17Bを形成して、重合部17S,17Sの先端が、それぞれ押込板用第二補強プレート15P、押込板用第三補強プレート16Pに溶接により固定されている。 By the way, the rear plate 17 for the push plate is passed to the second reinforcing plate 15P for the push plate and the third reinforcing plate 16P for the push plate, and the rear plate 17 for the push plate forms the bent portion 17B, and the overlapping portion 17S , 17S are fixed to the second reinforcing plate 15P for the push plate and the third reinforcing plate 16P for the push plate by welding, respectively.

この構成の押込板53において、塵芥による反力が負荷として押込板用前プレート13に働くことで、押込板用第二補強部材15および押込板用第三補強部材16が変形して押込板用第二補強プレート15Pおよび押込板用第三補強プレート16Pが変形すれば、その変形に応じて押込板用後プレート17も変形する。しかしながら、押込板用後プレート17には折曲部17Bが形成されている。このため、押込板用後プレート17の撓み(撓み量)は、折曲部17Bの変形として吸収される。押込板用後プレート17においては、折曲部17Bが変形することにより、その分だけ重合部17S,17Sにおける溶接部分に働く負荷が抑えられ、溶接部分の破損が防止できる。 In the push plate 53 having this configuration, the reaction force due to dust acts on the push plate front plate 13 as a load, so that the push plate second reinforcing member 15 and the push plate third reinforcing member 16 are deformed for the push plate. If the second reinforcing plate 15P and the third reinforcing plate 16P for the push plate are deformed, the rear plate 17 for the push plate is also deformed according to the deformation. However, a bent portion 17B is formed on the rear plate 17 for the push plate. Therefore, the bending (deflection amount) of the rear plate 17 for the push plate is absorbed as the deformation of the bent portion 17B. In the rear plate 17 for the push-in plate, since the bent portion 17B is deformed, the load acting on the welded portions in the polymerized portions 17S and 17S can be suppressed by that amount, and the welded portion can be prevented from being damaged.

そして、押込板用後プレート17の一方の重合部17Sの先端は、押込板用第三補強プレート16Pの表面に平行な状態で重ねられて溶接され、折曲部17Bは押込板用第三補強部材16の角部16Bに対応する部分に形成されている。この構成によれば、押込板用後プレート17の折曲部17Bは、重合部17Sと押込板用第三補強プレート16Pとの溶接部分の近傍において変形して、折曲部17Bよりも先端側での変形が抑えられることで、溶接部分に働く負荷が抑えられ、いっそう確実に溶接部分の破損が防止できる。 Then, the tip of one overlapping portion 17S of the rear plate 17 for the push plate is overlapped and welded in a state parallel to the surface of the third reinforcing plate 16P for the push plate, and the bent portion 17B is the third reinforcement for the push plate. It is formed in a portion corresponding to the corner portion 16B of the member 16. According to this configuration, the bent portion 17B of the rear plate 17 for the push plate is deformed in the vicinity of the welded portion between the overlapping portion 17S and the third reinforcing plate 16P for the push plate, and is on the tip side of the bent portion 17B. By suppressing the deformation in the welded portion, the load acting on the welded portion can be suppressed, and the welded portion can be prevented from being damaged more reliably.

溶接部分の破損が防止できれば、押込板用第二補強部材15、押込板用第三補強部材16の間への塵芥の侵入が防止できる。また、押込板用第二補強プレート15P、および押込板用第三補強プレート16Pは互いに平行ではなく傾斜角度が異なる。しかしながら、押込板用後プレート17に折曲部17Bを形成したことにより、重合部17S,17Sを押込板用第二補強プレート15P、および押込板用第三補強プレート16Pに平行な状態で重ねることができ、これにより重合部17S,17Sにおける溶接作業が容易になる。 If the welded portion can be prevented from being damaged, it is possible to prevent dust from entering between the second reinforcing member 15 for the push plate and the third reinforcing member 16 for the push plate. Further, the second reinforcing plate 15P for the push plate and the third reinforcing plate 16P for the push plate are not parallel to each other and have different inclination angles. However, by forming the bent portion 17B on the rear plate 17 for the push plate, the overlapping portions 17S and 17S are overlapped with the second reinforcing plate 15P for the push plate and the third reinforcing plate 16P for the push plate in a parallel state. This facilitates the welding work in the polymerized portions 17S and 17S.

以上、本発明につき一実施形態を取り上げて説明した。しかしながら、本発明は前記実施形態に限定されない。例えば、押込板53は前記実施形態では上部支持軸55を中心に揺動するものとしたが、これに限られず、例えば押込板53が直線方向や円弧方向に往復動したり、回転移動したりするように構成することもできる。 In the above, one embodiment of the present invention has been taken up and described. However, the present invention is not limited to the above embodiment. For example, in the above embodiment, the push plate 53 swings around the upper support shaft 55, but the present invention is not limited to this, and for example, the push plate 53 reciprocates or rotates in a linear direction or an arc direction. It can also be configured to do so.

上記実施形態において、回転板用後プレート8における折曲部8B,8Bは二箇所に形成され、押込板用後プレート17における折曲部17Bは一箇所に形成された場合を例示した。しかしながら、折曲部は、三箇所あるいはそれ以上の箇所で折曲することもできる。上記実施形態において、折曲部は後方へ向けて凸とする構成とした。しかしながら、回転板用補強部材の回転板用補強プレート、押込板世補強部材の押込板用補強プレートの傾斜方向に応じて、場合によっては折曲部を前方へ向けて凸とする構成とすることもできる。 In the above embodiment, the case where the bent portions 8B and 8B of the rotating plate rear plate 8 are formed at two locations and the bent portions 17B of the push plate rear plate 17 are formed at one location is illustrated. However, the bent portion can also be bent at three or more points. In the above embodiment, the bent portion is configured to be convex toward the rear. However, depending on the inclination direction of the reinforcing plate for the rotating plate of the reinforcing member for the rotating plate and the reinforcing plate for the pushing plate of the pushing plate world reinforcing member, the bent portion may be convex toward the front in some cases. You can also.

上記実施形態では、全ての重合部を、これが重ねられる補強プレートに溶接した場合を例示した。しかしながら、回転板用後プレート8、押込板用後プレート17における何れかの重合部のうちの一方は、補強プレートに溶接されていなくておらず、補強プレートの表面に重ねられている構成であってもよい。また、折曲部は、角部に対応する部位以外の架渡部にあってもよい。何れにしても、折曲部を形成することにより、補強プレートと後プレートとを平行に重ね易いため、補強プレートに後プレートを重ねた状態で溶接作業がし易く、補強プレートと後プレートとの間に隙間が生じた状態で溶接されてしまう場合に比べて、溶接部分の破損を効果的に抑制し得る。つまり、両プレートが平行に重なり合っていることで、前プレートが撓んで補強プレートが動くときに、重なり合ったまま動き、両プレートの相対位置が変わらないので、溶接部にかかる負荷を抑制でき、溶接部の破損を防止できる。 In the above embodiment, the case where all the polymerized parts are welded to the reinforcing plate on which they are overlapped is illustrated. However, one of the overlapping portions of the rear plate 8 for the rotating plate and the rear plate 17 for the push plate is not welded to the reinforcing plate, but is overlapped on the surface of the reinforcing plate. You may. Further, the bent portion may be located in a connecting portion other than the portion corresponding to the corner portion. In any case, by forming the bent portion, the reinforcing plate and the rear plate can be easily stacked in parallel, so that the welding work can be easily performed with the rear plate stacked on the reinforcing plate, and the reinforcing plate and the rear plate can be stacked. Damage to the welded portion can be effectively suppressed as compared with the case where the weld is welded with a gap between them. In other words, because both plates overlap in parallel, when the front plate bends and the reinforcing plate moves, it moves while overlapping, and the relative positions of both plates do not change, so the load on the weld can be suppressed and welding can be performed. It is possible to prevent damage to the part.

上記実施形態では、積込装置において、回転板52および押込板53の双方に、補強部材の補強プレートに平行な状態で重ねられる重合部、および折曲部を形成した後プレートを設け、重合部の端部を補強プレートの表面に溶接した構成を例示した。しかしながら、このような後プレートは、回転板52および押込板53の何れか一方にのみ設ける構成としてもよい。 In the above embodiment, in the loading device, both the rotating plate 52 and the pushing plate 53 are provided with a superposed portion to be stacked in parallel with the reinforcing plate of the reinforcing member and a post-plate formed with a bent portion, and the superposed portion is provided. The configuration in which the end portion of the sword is welded to the surface of the reinforcing plate is illustrated.
