[First Embodiment]
The load discharge auxiliary unit 1 according to the first embodiment of the present invention will be described. 1 and 2, the load discharge assisting unit 1 according to the present embodiment is used by being attached to a dump-type loading platform 9 used for a dump truck D or the like, and is a guide as a partitioning means. The member 2 and one or a plurality of (two in the example of FIG. 1) opening restriction members 4 are provided. As long as the guide member 2 and the opening restriction member 4 have sufficient rigidity, the material thereof is not limited and may be made of wood or steel, or may be made of a synthetic resin such as acrylic resin or ABS resin. . The loading platform 9 includes a pair of left and right side plates 91, 91 (left side plate 91 </ b> L, right side plate 91 </ b> R) and a tilt plate 92 provided at the rear of the loading platform 9, and the rear end of the guide member 2 is one side plate 91 of the loading platform 9. (The left side plate 91L in the example of FIG. 1) is slanted between the other side plate 91 (right side plate 91R in the example of FIG. 1) and the tilt plate 92 so as to be separated by a predetermined distance L1. Thereby, the internal space of the loading platform 9 is partitioned into a loading space S1 in which the width dimension of the rear region gradually decreases toward the rear, and another non-loading space S2.

図3をも参照して、ガイド部材2は一側面が開放された浅箱形に形成されており、ベース板21と、ベース板21の周縁から側方へ延出する4枚の側板22(上板22a、底板22b、後板22c、前板22d)とを備える。ガイド部材2は、開放面が非積載空間S2に面するように配置され、ベース板21の外側の平坦面(積載空間S1側の面)がガイド面21aとして機能する。後板22cは、ベース板21から離隔するにつれて内側へ傾斜するように形成されている。上板22aの前端近傍位置には上板22aを厚み方向に貫通する開口部Hが形成されており、この開口部Hに下向略U字状の係合部材23の一端部が挿通され、その下端部には抜止部材24が設けられている。この係合部材23を荷台9の側板91に係止させることで、係合部材23を介してガイド部材2が荷台9の側板91に連結される。なお、ガイド部材2の高さは、荷台9の側板91とほぼ等しい或いは側板91よりも幾分高く設定するのが好ましく、具体的には35〜45cmであるのが好ましく、40cmであるのが更に好ましい。   Referring also to FIG. 3, the guide member 2 is formed in a shallow box shape with one side open, and includes a base plate 21 and four side plates 22 extending sideways from the periphery of the base plate 21 ( An upper plate 22a, a bottom plate 22b, a rear plate 22c, and a front plate 22d). The guide member 2 is disposed such that the open surface faces the non-loading space S2, and the flat surface outside the base plate 21 (the surface on the loading space S1 side) functions as the guide surface 21a. The rear plate 22c is formed so as to be inclined inward as the distance from the base plate 21 increases. An opening H penetrating the upper plate 22a in the thickness direction is formed in the vicinity of the front end of the upper plate 22a, and one end of a downward substantially U-shaped engaging member 23 is inserted into the opening H, A retaining member 24 is provided at the lower end portion. By engaging the engaging member 23 with the side plate 91 of the loading platform 9, the guide member 2 is coupled to the side plate 91 of the loading platform 9 via the engaging member 23. The height of the guide member 2 is preferably set to be substantially equal to or slightly higher than the side plate 91 of the loading platform 9, specifically 35 to 45 cm, specifically 40 cm. Further preferred.

図4をも参照して、開度規制部材4は、水平方向に延出する第1当接部としてのベース部41と、ベース部41の後端部に設けられた鉤状部42とを備え、鉤状部42は側面視略下向コ字型に形成されている。より具体的に、鉤状部42は、ベース部41の後端部から上方に起立する第2当接部42aと、第2当接部42aと実質上平行に延びる当接部42bと、第2当接部42aの上端と当接部42bの上端とを接続する接続部42cとを備える。本実施形態においては、ベース部41は長尺平板状に形成され、第2当接部42a、当接部42b、及び接続部42cは、角棒状に形成されている。   Referring also to FIG. 4, the opening degree regulating member 4 includes a base portion 41 as a first abutting portion extending in the horizontal direction, and a hook-like portion 42 provided at the rear end portion of the base portion 41. And the hook-like portion 42 is formed in a substantially downward U-shape when viewed from the side. More specifically, the bowl-shaped portion 42 includes a second contact portion 42a that rises upward from the rear end portion of the base portion 41, a contact portion 42b that extends substantially parallel to the second contact portion 42a, 2 includes a connecting portion 42c that connects the upper end of the abutting portion 42a and the upper end of the abutting portion 42b. In the present embodiment, the base portion 41 is formed in a long flat plate shape, and the second contact portion 42a, the contact portion 42b, and the connection portion 42c are formed in a square bar shape.

この開度規制部材4は、図1及び図5に示す様に、ベース部41が荷台9の非積載空間S2に位置すると共に、鉤状部42の第2当接部42aと当接部42bとがアオリ板92を挟んで互いに対向するように設置される。この状態で荷台9を後方に傾斜させる(ダンプアップさせる)と、自重によってアオリ板92が開く。即ち、アオリ板92は回動軸94(図1)を中心に回動し、その下端が荷台9の底板93に対して相対的に後方へ移動し、荷台9の底板93とアオリ板92の間に隙間が生じる。荷台9の底板93とアオリ板92の下端との隙間、即ちアオリ板92の開度は、荷台9の傾斜角度が増すに従い大きくなるが、傾斜角度が所定角度に達すると、アオリ板92の内側上端部(より具体的にはアオリ板92の内面と上面との角部)及び外側下端部(より具体的にはアオリ板92の外面と底面との角部)が開度規制部材4の第2当接部42a及び当接部42bにそれぞれ当接し(図6参照)、またベース部41が荷台9の底面(底板93)に当接することで、アオリ板92のそれ以上の回動(開方向への移動)が阻止される。よって、アオリ板92の内側上端部及び外側下端部が開度規制部材4の第2当接部42a及び当接部42bにそれぞれ当接した状態において、荷台9の底板93とアオリ板92の下端との距離(即ち、アオリ板92の開度)が最大距離L2となる。   As shown in FIGS. 1 and 5, the opening degree regulating member 4 includes a base portion 41 positioned in the non-loading space S <b> 2 of the loading platform 9, and a second contact portion 42 a and a contact portion 42 b of the bowl-shaped portion 42. Are installed so as to face each other across the tilt plate 92. If the loading platform 9 is tilted backward (dumped up) in this state, the tilt plate 92 is opened by its own weight. That is, the tilt plate 92 rotates around the rotation shaft 94 (FIG. 1), and the lower end thereof moves relatively rearward with respect to the bottom plate 93 of the cargo bed 9, so that the bottom plate 93 of the cargo bed 9 and the tilt plate 92 There is a gap between them. The clearance between the bottom plate 93 of the loading platform 9 and the lower end of the tilting plate 92, that is, the opening of the tilting plate 92 increases as the tilting angle of the loading platform 9 increases, but when the tilting angle reaches a predetermined angle, the inner side of the tilting plate 92 is increased. The upper end portion (more specifically, the corner portion between the inner surface and the upper surface of the tilt plate 92) and the outer lower end portion (more specifically, the corner portion between the outer surface and the bottom surface of the tilt plate 92) 2 Abuts against the abutting portion 42a and the abutting portion 42b (see FIG. 6), and the base portion 41 abuts against the bottom surface (bottom plate 93) of the cargo bed 9, thereby further rotating (opening) the tilt plate 92. Movement in the direction) is prevented. Therefore, the bottom plate 93 of the loading platform 9 and the bottom end of the tilt plate 92 in a state where the inner upper end portion and the outer lower end portion of the tilt plate 92 are in contact with the second contact portion 42a and the contact portion 42b of the opening degree regulating member 4, respectively. (That is, the opening of the tilt plate 92) is the maximum distance L2.

このようにアオリ板92の開度を規制することにより、アオリ板92が全開となるのが防止され、荷台9が傾斜した際にガイド部材2が落下するのを防止できる。即ち、ダンプカーDが2トンタイプの場合、アオリ板92を全開させると、荷台9の開口部の高さ(荷台9の底板93からアオリ板92までの距離)は約60cm程度となり、3トンタイプの場合には開口部の高さはそれ以上となるため、ガイド部材2の高さを相当程度高く設定しない限り、荷台9を傾斜させた際にガイド部材2は開口部を介して荷台9から落下してしまう。しかしながら、上述したようにアオリ板92の開度を規制することにより、ガイド部材2は開口部を介して落下することなく、アオリ板92に当接して支持される。   By restricting the opening of the tilt plate 92 in this way, the tilt plate 92 is prevented from being fully opened, and the guide member 2 can be prevented from falling when the loading platform 9 is inclined. That is, when the dump truck D is a 2-ton type, when the tilt plate 92 is fully opened, the height of the opening of the loading platform 9 (the distance from the bottom plate 93 of the loading platform 9 to the tilt plate 92) is about 60 cm. In this case, since the height of the opening is higher than that, unless the height of the guide member 2 is set to be considerably high, the guide member 2 is moved from the load bed 9 through the opening when the load bed 9 is inclined. It will fall. However, by restricting the opening degree of the tilt plate 92 as described above, the guide member 2 is supported in contact with the tilt plate 92 without falling through the opening.

このように形成された荷台9の開口部(荷台9の底板93とアオリ板92の下端との隙間)のうち、積載空間S1と連通する部分、即ちガイド部材2の後端よりも一方の側板91(左側板91L)寄りの部位が荷台9の排出口Pとして機能し、作業者は、この排出口Pを介して積載空間S1に積載された砂等の積荷(図示せず)を運搬具Eへ排出・移載することができる。即ち、作業者は図2に示す様に予め排出口Pの下方位置となる所定位置に運搬具Eを配置させておき、荷台9を傾斜させる。すると、排出口Pが開口すると共に、積荷は自重により排出口Pへ向かって後方へ移動する。よって、作業者は、鍬やホー等の道具(図示せず)を用いて積荷を排出口Pから下方へ落とすようにして運搬具Eへ排出・移載させることができる。また、積荷が積載される積載空間S1は、その後部の幅寸法が排出口Pへ向かって漸減するようにガイド部材2によって規定されているため、積荷をガイド部材2のガイド面21aに沿ってスムーズに排出口P側へ集めることができる。   Of the opening of the loading platform 9 formed in this way (the gap between the bottom plate 93 of the loading platform 9 and the lower end of the tilt plate 92), the side plate that is in communication with the loading space S1, that is, one side plate from the rear end of the guide member 2. A portion near 91 (left side plate 91L) functions as a discharge port P of the loading platform 9, and the operator carries a load (not shown) such as sand loaded in the loading space S1 through the discharge port P. E can be discharged and transferred to E. That is, as shown in FIG. 2, the operator places the transporting device E in a predetermined position that is a position below the discharge port P in advance, and tilts the loading platform 9. Then, the discharge port P is opened, and the load moves rearward toward the discharge port P due to its own weight. Therefore, the operator can discharge and transfer the load to the transport device E by dropping the load from the discharge port P using a tool (not shown) such as a hoe or ho. Further, since the loading space S1 in which the load is loaded is defined by the guide member 2 so that the width dimension of the rear portion thereof gradually decreases toward the discharge port P, the load is loaded along the guide surface 21a of the guide member 2. It can be smoothly collected to the discharge port P side.

なお、荷台9の傾斜角度に制限はないが、荷台9を傾斜させるに従い荷台9の後端部の高さ位置が下降していくため、荷台9を最大傾斜角度まで傾斜させた場合には、排出口Pの下方に運搬具Eとしての一輪車を置くだけの十分なスペースが確保されない場合がある。よって、このような場合には、一輪車を置けるだけのスペースが確保できる範囲内で荷台9を傾斜させればよい。   Although there is no limitation on the tilt angle of the loading platform 9, the height position of the rear end of the loading platform 9 is lowered as the loading platform 9 is tilted. Therefore, when the loading platform 9 is tilted to the maximum tilt angle, There may be a case where a sufficient space for placing the unicycle as the carrier E under the discharge port P is not secured. Therefore, in such a case, the loading platform 9 may be tilted within a range in which a space sufficient for placing a unicycle can be secured.

ここで、ガイド部材2の後端と荷台9の一方の側板91(左側板91L)との間隔(排出口Pの左右幅)L1は、次のように設定するのが好ましい。即ち、図2に示す様に、運搬具Eとして一輪車を用い、一輪車をダンプカーDに対して横向き(図2に示す向き)に置く場合には、排出口Pの左右幅L1は50cm程度であるのが好ましい。50cmを大幅に超えると排出口Pから排出された砂等の積荷が運搬具Eからこぼれてしまい、50cmよりも大幅に小さいと作業効率が悪くなる。同様の理由により、運搬具Eとして一輪車を用い、一輪車をダンプカーDと平行(図2の向きに対して垂直)に置く場合には、排出口Pの左右幅L1は30cm程度であるのが好ましい。更に、運搬具Eとしてバケツを用いる場合には、排出口Pの左右幅L1は約15cmであるのが好ましい。   Here, it is preferable to set the distance (left-right width of the discharge port P) L1 between the rear end of the guide member 2 and one side plate 91 (left side plate 91L) of the loading platform 9 as follows. That is, as shown in FIG. 2, when a unicycle is used as the transporter E and the unicycle is placed sideways with respect to the dump truck D (the direction shown in FIG. 2), the left-right width L1 of the discharge port P is about 50 cm. Is preferred. If it greatly exceeds 50 cm, a load such as sand discharged from the discharge port P will be spilled from the carrier E, and if it is much smaller than 50 cm, the work efficiency will deteriorate. For the same reason, when a unicycle is used as the carrier E and the unicycle is placed parallel to the dump truck D (perpendicular to the direction of FIG. 2), the left-right width L1 of the discharge port P is preferably about 30 cm. . Furthermore, when a bucket is used as the transporting device E, the left-right width L1 of the discharge port P is preferably about 15 cm.

また、排出口Pの前後幅(荷台9の底板93とアオリ板92との最大距離)L2は、10cm〜20cm程度であるのが好ましい。運搬具Eとしてバケツを用いた場合に排出口Pの前後幅L2が20cmを超えると、排出口Pから排出された砂等が運搬具Eからこぼれ易くなってしまう。また、運搬具Eとして一輪車を用いた場合においても、前後幅L2が20cmを超えると、次の様な問題が生じる。即ち、上述したように、荷台9を傾斜させるに従い荷台9の後端の高さ位置が下降していくため、排出口Pの下方に一輪車を配置するスペースを確保する必要性から、荷台9の傾斜角度は制限される。排出口Pの前後幅L2を大きく設定すると、その分だけアオリ板92の下端の高さ位置も低くなり、この場合には荷台9の傾斜角度が更に制限される。すると、荷台9を大きく傾斜させることができなくなり、積荷を自重によって荷台9の後方へ効率良く移動させることができなくなる恐れが生じる。一方、排出口Pの前後幅L2が10cmより小さいと、作業効率が低下するという問題が生じる。   Moreover, it is preferable that the front-rear width (maximum distance between the bottom plate 93 and the tilt plate 92) L2 of the discharge port P is about 10 cm to 20 cm. If a front and rear width L2 of the discharge port P exceeds 20 cm when a bucket is used as the transport device E, sand or the like discharged from the discharge port P is likely to spill from the transport device E. In addition, even when a unicycle is used as the transporter E, the following problems occur when the front-rear width L2 exceeds 20 cm. That is, as described above, since the height position of the rear end of the loading platform 9 is lowered as the loading platform 9 is tilted, it is necessary to secure a space for placing the unicycle below the discharge port P. The tilt angle is limited. When the front and rear width L2 of the discharge port P is set to be large, the height position of the lower end of the tilt plate 92 is also lowered accordingly, and in this case, the inclination angle of the loading platform 9 is further limited. Then, the loading platform 9 cannot be inclined greatly, and there is a possibility that the load cannot be efficiently moved to the rear of the loading platform 9 by its own weight. On the other hand, when the front-rear width L2 of the discharge port P is smaller than 10 cm, there arises a problem that work efficiency is lowered.

ここで、荷台9を傾斜させてアオリ板92が開くと、これに従いアオリ板92の上端が荷台9の側板91から離れるように後方へ移動し、その結果、開度規制部材4も全体的に後方へ移動する(図6参照)。一方で、アオリ板92は所定の厚さを有することから、開度規制部材4の第2当接部42aと当接部42bの距離L3(図4)は、結果的に排出口Pの前後幅L2とほぼ等しくなる。よって、開度規制部材4の第2当接部42aと当接部42bの距離L3も、前後幅L2と同様に、10cm〜20cmに設定するのが好ましく、約15cmとするのが更に好ましい。   Here, when the tilting plate 92 is opened by tilting the loading platform 9, the upper end of the tilting plate 92 moves rearwardly away from the side plate 91 of the loading platform 9, and as a result, the opening degree regulating member 4 is also entirely It moves backward (see FIG. 6). On the other hand, since the tilt plate 92 has a predetermined thickness, the distance L3 (FIG. 4) between the second contact portion 42a and the contact portion 42b of the opening degree restricting member 4 is the front and back of the discharge port P as a result. It becomes substantially equal to the width L2. Therefore, the distance L3 between the second contact portion 42a and the contact portion 42b of the opening degree regulating member 4 is preferably set to 10 cm to 20 cm, and more preferably about 15 cm, similarly to the front-rear width L2.

更に、開度規制部材4の高さは、図5に示す様に開度規制部材4を荷台9に設置した際に、連結部42cの下面がアオリ板92の上端よりも幾分上方に位置するように設定するのが好ましい。このように設定することにより、連結部42cとアオリ板92との間に若干の隙間Gが生じることになり、アオリ板92が図5の状態から図6の状態へ回動する際にアオリ板92の後上角部92Cによって開度規制部材4が上方へ押し上げられるのを防止できる。ここで、ベース部41の底面から連結部42cの底面までの距離L4は45〜50cmに設定するのが好ましい。距離L4を45cm以上とすることにより、開度規制部材4を2トンタイプ及び3トンタイプのダンプカーについて共通に用いることができると共に、50cm以下とすることにより、開度規制部材4が不必要に大型化するのを防止できる。   Further, the height of the opening restriction member 4 is such that the lower surface of the connecting portion 42c is located slightly above the upper end of the tilt plate 92 when the opening restriction member 4 is installed on the loading platform 9 as shown in FIG. It is preferable to set so as to. By setting in this way, a slight gap G is generated between the connecting portion 42c and the tilt plate 92, and when the tilt plate 92 rotates from the state of FIG. 5 to the state of FIG. The opening restriction member 4 can be prevented from being pushed upward by the rear upper corner portion 92C of the 92. Here, the distance L4 from the bottom surface of the base portion 41 to the bottom surface of the connecting portion 42c is preferably set to 45 to 50 cm. By setting the distance L4 to 45 cm or more, the opening degree regulating member 4 can be used in common for 2 ton type and 3 ton type dump trucks, and by making the distance L4 to 50 cm or less, the opening degree regulating member 4 is unnecessary. An increase in size can be prevented.

次に、このように構成された積荷排出補助ユニット1を用いた積荷排出方法について説明する。この積荷排出補助ユニット1を用いて積荷を排出する場合には、荷台9に積荷を積み込む前に、水平状態に保たれた荷台9に対してガイド部材2を所要の通りに予め設置しておく。より具体的に、荷台9が水平の状態では、アオリ板92は荷台9の底板93の後端に当接しており、排出口Pは閉じられている。また、アオリ板92はロック部材(図示せず)により閉状態にロックされている。この状態で、ガイド部材2を荷台9の側板91(他方の側板;右側板91R)からアオリ板92まで斜めに配置し、その前端部と後端部とを当該側板91(91R)とアオリ板92にそれぞれ当接させ、荷台9の内部空間を積載空間S1と非積載空間S2とへ区画する。荷台9の側板91(一方の側板;左側板91L)とガイド部材2の後端との距離L1が、使用する搬送具Eに対応する所定距離となるように位置調整し、係合部材23を側板91(91R)の上端に係止させる。   Next, a load discharge method using the load discharge auxiliary unit 1 configured as described above will be described. When discharging a load using the load discharge assisting unit 1, the guide member 2 is installed in advance as required on the load platform 9 maintained in a horizontal state before loading the load on the load platform 9. . More specifically, when the loading platform 9 is horizontal, the tilt plate 92 is in contact with the rear end of the bottom plate 93 of the loading platform 9 and the discharge port P is closed. Further, the tilt plate 92 is locked in a closed state by a lock member (not shown). In this state, the guide member 2 is disposed obliquely from the side plate 91 (the other side plate; right side plate 91R) of the loading platform 9 to the tilt plate 92, and the front end portion and the rear end portion thereof are connected to the side plate 91 (91R) and the tilt plate. The inner space of the loading platform 9 is partitioned into a loading space S1 and a non-loading space S2. The position is adjusted so that the distance L1 between the side plate 91 (one side plate; left side plate 91L) of the loading platform 9 and the rear end of the guide member 2 is a predetermined distance corresponding to the transport tool E to be used, and the engaging member 23 is moved. The upper end of the side plate 91 (91R) is locked.

このようにガイド部材2が設置された状態で、荷台9の積載空間S1に砂や砂利等の積荷を積載し、建築現場等の目的地へ運搬する。目的地に到達後、非積載空間S2に対応させて、開度規制部材4を荷台9の後端部に設置する。このとき、鉤状部42の第2当接部42aはアオリ板92の内面と当接させるのが好ましい(図5参照)。次に、バケツや一輪車等の運搬具Eを所定位置に配置する。この所定位置の上方に、荷台9の排出口Pが位置することになる。次に、荷台9を後方へ傾斜させる(ダンプアップさせる)と、アオリ板92のロック部材が解除され、排出口Pが開口するので、作業者は鍬やホー等を用いて積荷を排出口Pから下方へ落とすようにして運搬具Eへ排出・移載させる。排出口P付近の積荷をある程度排出させたら、荷台9を更に傾斜させ、残りの積荷を自重によって荷台9の後方へ移動させて、排出口Pから排出させる。以降、同様の作業を繰り返すことにより、作業者は荷台9に登らなくても、全ての積荷を容易に排出させることができる。   With the guide member 2 installed in this way, a load such as sand or gravel is loaded in the loading space S1 of the loading platform 9 and transported to a destination such as a building site. After reaching the destination, the opening degree regulating member 4 is installed at the rear end of the loading platform 9 in correspondence with the non-loading space S2. At this time, it is preferable that the second contact portion 42a of the bowl-shaped portion 42 is in contact with the inner surface of the tilt plate 92 (see FIG. 5). Next, a carrying device E such as a bucket or a unicycle is placed at a predetermined position. The discharge port P of the loading platform 9 is positioned above the predetermined position. Next, when the loading platform 9 is tilted backward (dumped up), the locking member of the tilt plate 92 is released and the discharge port P is opened, so that the operator discharges the load using a hoe, ho, etc. It is discharged and transferred to the carrier E as if it is dropped downwards. When the load in the vicinity of the discharge port P is discharged to some extent, the loading platform 9 is further tilted, and the remaining load is moved to the rear of the loading platform 9 by its own weight and discharged from the discharge port P. Thereafter, by repeating the same operation, the operator can easily discharge all the cargo without climbing on the loading platform 9.

このように、本実施形態の積荷排出補助ユニット1によれば、所定幅L1,L2を有すると共に下方に開口する排出口Pを規定することができるので、この排出口Pから積荷を落とすようにして運搬具Eに積荷を排出・移載させることができ、積荷の排出作業を効率良く行うことができる。また、ガイド部材2によって区画された荷台9の積載空間S1は、排出口Pに向かってその幅寸法が漸減しているため、ガイド部材2のガイド面21aに沿って積荷を排出口Pに向かって容易に集めることができる。更に、ガイド部材2の荷台9への設置は、ガイド部材2を荷台9の底面(底板93)に載置した後に係合部材23を荷台9の側板91に係止させるだけでよく、また開度規制部材4の荷台9への設置も、開度規制部材4を荷台9の所定位置に載置させるだけでよく、工具等を用いなくても極めて容易にガイド部材2及び開度規制部材4の着脱を行うことができる。   Thus, according to the load discharge auxiliary unit 1 of the present embodiment, the discharge port P having the predetermined widths L1 and L2 and opening downward can be defined, so that the load is dropped from the discharge port P. Thus, the load can be discharged / transferred to the transporter E, and the discharge operation of the load can be performed efficiently. Further, since the loading space S1 of the loading platform 9 partitioned by the guide member 2 gradually decreases in width toward the discharge port P, the load is directed toward the discharge port P along the guide surface 21a of the guide member 2. Can be collected easily. Further, the guide member 2 can be installed on the loading platform 9 only by locking the engaging member 23 to the side plate 91 of the loading platform 9 after the guide member 2 is placed on the bottom surface (bottom plate 93) of the loading platform 9. The degree regulating member 4 can be installed on the loading platform 9 only by placing the opening regulating member 4 at a predetermined position on the loading platform 9, and the guide member 2 and the opening regulating member 4 can be very easily used without using a tool or the like. Can be attached and detached.

[第2実施形態]
次に、図7を参照して、本発明の第2実施形態に係る積荷排出補助ユニット101について説明する。なお、上述した第1実施形態に係る積荷排出補助ユニット1と実質同一の構成については同一の符号を付し、詳細な説明は省略する。
[Second Embodiment]
Next, the load discharge assisting unit 101 according to the second embodiment of the present invention will be described with reference to FIG. In addition, about the structure substantially the same as the cargo discharge auxiliary unit 1 which concerns on 1st Embodiment mentioned above, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

本実施形態における積荷排出補助ユニット101は、上述した積荷排出補助ユニット1と実質同一の構成を有するが、区画手段として一対のガイド部材2,2を備える点で異なる。即ち、図7に示す様に、一対のガイド部材2,2は略逆ハ字状となるようにダンプ式の荷台9に設置され、荷台9の内部空間を1の積載空間S1と、積載空間S1の両側後方に位置する2つの非積載空間S2,S2へ区画する。   The load discharge auxiliary unit 101 in this embodiment has substantially the same configuration as the load discharge auxiliary unit 1 described above, but is different in that it includes a pair of guide members 2 and 2 as partitioning means. That is, as shown in FIG. 7, the pair of guide members 2 and 2 are installed on a dump-type loading platform 9 so as to have a substantially inverted C shape, and the interior space of the loading platform 9 is defined as one loading space S1 and a loading space. It is divided into two non-loading spaces S2, S2 located on both sides rear side of S1.

より具体的に、右側のガイド部材2(一方のガイド部材)は、荷台9の右側板91R(一方の側板)から後方に向かって内側へ傾斜して配置され、左側のガイド部材2(他方のガイド部材)は、荷台9の左側板91L(他方の側板)から後方に向かって内側へ傾斜して配置され、右側のガイド部材2の後端と左側のガイド部材2の後端とは所定距離L1だけ離隔し、ここに排出口Pが形成されることとなる。また、右側のガイド部材2の前端部に設けられた係止部材23は右側板91Rの上端に係止され、左側のガイド部材2の前端部に設けられた係止部材23は左側板91Lの上端に係止される。複数の開度規制部材4を用いる場合には、2つの非積載空間S2,S2のそれぞれに対応させて開度規制部材4が設置される。   More specifically, the right guide member 2 (one guide member) is disposed to be inclined inwardly from the right side plate 91R (one side plate) of the loading platform 9 and the left side guide member 2 (the other guide member 2). The guide member is inclined inwardly rearward from the left side plate 91L (the other side plate) of the loading platform 9, and the rear end of the right guide member 2 and the rear end of the left guide member 2 are a predetermined distance. The outlet P is formed at a distance L1 apart. The locking member 23 provided at the front end portion of the right guide member 2 is locked at the upper end of the right side plate 91R, and the locking member 23 provided at the front end portion of the left side guide member 2 is fixed to the left side plate 91L. Locked to the top. When a plurality of opening degree regulating members 4 are used, the opening degree regulating members 4 are installed so as to correspond to the two non-loading spaces S2 and S2.

本実施形態においても、第1実施形態に係る積荷排出補助ユニット1と同様に、排出口Pから積荷を効率良く排出させることができる。   Also in the present embodiment, the load can be efficiently discharged from the discharge port P in the same manner as the load discharge auxiliary unit 1 according to the first embodiment.

ここで、積荷は荷台9の後方部位から順次排出させていくため、荷台9の前方角部付近に積荷が残りやすく、積荷が水分を含んだ砂等の場合には特に、荷台9をある程度傾斜させただけでは排出口Pに向かって落下せず、荷台9の前方角部に積荷が残ってしまうことがある。この場合には、次の手法を採用することにより、積荷の排出を更に効率良く行うことができる。   Here, since the load is sequentially discharged from the rear part of the loading platform 9, the loading tends to remain near the front corner of the loading platform 9, and the loading platform 9 is inclined to some extent, particularly in the case of sand containing moisture. If it just makes it fall, it will not fall toward the discharge port P, but a load may remain in the front corner part of the loading platform 9. In this case, it is possible to discharge the cargo more efficiently by adopting the following method.

まず、排出口Pの近傍位置において、落下防止板5を一対のガイド部材2,2の間に渡すようにして荷台9の底面(底板93)に載置する。ここで、運搬具Eとしての一輪車が排出口Pの下方位置に置かれている場合には、これを一端移動させておき、荷台9を最大傾斜角度まで傾斜させる。一輪車を一端移動させておくのは、荷台9を最大傾斜角度まで傾斜させた際にアオリ板92が一輪車に衝突するのを回避するためである。このように荷台9を最大傾斜角度まで傾斜させると、水分を含んだ砂等であっても自重により落下し、排出口Pから一気に排出されることなく落下防止板5により堰き止められる。ここで、一対のガイド部材2,2は略逆向ハ字状に配置されているため、落下防止板5を一対のガイド部材2,2間に渡しておくだけで、特別な保持具を用いなくても落下防止板5はガイド部材2,2により支持される。その後、荷台9の傾斜角度を緩め、運搬具Eを排出口Pの下方位置へ設置し、落下防止板5を取り外した後に、排出口Pから積荷を排出させればよい。   First, in the vicinity of the discharge port P, the fall prevention plate 5 is placed on the bottom surface (bottom plate 93) of the cargo bed 9 so as to pass between the pair of guide members 2 and 2. Here, when the unicycle as the transporter E is placed at a position below the discharge port P, the unicycle is moved one end, and the loading platform 9 is tilted to the maximum tilt angle. The reason why the unicycle is moved one end is to prevent the tilt plate 92 from colliding with the unicycle when the loading platform 9 is tilted to the maximum tilt angle. When the loading platform 9 is tilted to the maximum tilt angle in this way, even sand containing moisture falls due to its own weight and is blocked by the fall prevention plate 5 without being discharged from the discharge port P at a stretch. Here, since the pair of guide members 2 and 2 are arranged in a substantially reverse C-shape, only the fall prevention plate 5 is passed between the pair of guide members 2 and 2 without using a special holder. Even so, the fall prevention plate 5 is supported by the guide members 2 and 2. Then, the inclination angle of the loading platform 9 is relaxed, the carrier E is installed at a position below the discharge port P, the fall prevention plate 5 is removed, and then the cargo is discharged from the discharge port P.

なお、上述した第1実施形態の積荷排出補助ユニット1を用いた場合であっても、落下防止板5を荷台9の側板91とガイド部材2の間に渡すことにより、これと同様の手法を用いて積荷を荷台9の後方へ集めることもできる。この場合には、固定手段(図示せず)を用いて落下防止板5を荷台9の側板91に固定させればよい。また、第2実施形態においても、固定手段(図示せず)を用いて落下防止板5を一対のガイド部材2,2に固定し、安定性を確保してもよい。   Even when the load discharge auxiliary unit 1 of the first embodiment described above is used, the same method can be used by passing the fall prevention plate 5 between the side plate 91 of the loading platform 9 and the guide member 2. It is also possible to collect the load behind the loading platform 9 by using it. In this case, the fall prevention plate 5 may be fixed to the side plate 91 of the loading platform 9 using a fixing means (not shown). Also in the second embodiment, the fall prevention plate 5 may be fixed to the pair of guide members 2 and 2 using a fixing means (not shown) to ensure stability.

[第3実施形態]
次に、図8及び図9を参照して、本発明の第3実施形態に係る積荷排出補助ユニットについて説明する。なお、上述した第1又は第2実施形態に係る積荷排出補助ユニット1,101と実質同一の構成については同一の符号を付し、詳細な説明は省略する。
[Third Embodiment]
Next, with reference to FIG.8 and FIG.9, the load discharge auxiliary | assistance unit which concerns on 3rd Embodiment of this invention is demonstrated. In addition, the same code | symbol is attached | subjected about the structure substantially the same as the cargo discharge auxiliary units 1 and 101 which concern on 1st or 2nd embodiment mentioned above, and detailed description is abbreviate | omitted.

本実施形態における積荷排出補助ユニット201は、第2実施形態に係る積荷排出補助ユニット101と実質同一の構成を有するが、一対のガイド部材2,2が連結部材6にて連結される点で異なる。この連結部材6は、右側のガイド部材2の後端と左側のガイド部材2の後端との距離を所定距離L1に維持するものであって、所定長さを有する棒状部材61の両端から係止部62,62が下方に延出されて構成されている。また、各ガイド部材2のガイド面21aには略横向U字状の被係止部25が設けられている。この被係止部25に連結部材6の各係止部62を係止することにより、一対のガイド部材2,2が連結部材6にて連結され、所定距離L1を維持しつつ、ガイド部材2,2を安定させることができる。   The load discharge auxiliary unit 201 in the present embodiment has substantially the same configuration as the load discharge auxiliary unit 101 according to the second embodiment, but differs in that a pair of guide members 2 and 2 are connected by a connecting member 6. . The connecting member 6 maintains the distance between the rear end of the right guide member 2 and the rear end of the left guide member 2 at a predetermined distance L1, and is engaged from both ends of the rod-shaped member 61 having a predetermined length. Stop portions 62, 62 are configured to extend downward. Further, the guide surface 21 a of each guide member 2 is provided with a substantially U-shaped locked portion 25. By locking each locking portion 62 of the connecting member 6 to the locked portion 25, the pair of guide members 2 and 2 are connected by the connecting member 6, and the guide member 2 is maintained while maintaining a predetermined distance L1. , 2 can be stabilized.

なお、連結部材6としては、所定距離(即ち排出口Pの左右幅)L1に合わせて長さ50cm程度のもの、長さ30cm程度のもの、及び長さ15cm程度のものを用意し、運搬具Eの種類等に応じて使い分けるようにすればよい。   In addition, as the connection member 6, the thing about 50 cm in length, the thing about 30 cm in length, and the thing about 15 cm in length are prepared according to predetermined distance (namely, left-right width of the discharge port P), and a carrier What is necessary is just to use properly according to the kind etc. of E.

[第4実施形態]
次に、本発明の第4実施形態に係る開度規制部材について説明する。なお、以下の各実施形態において、上述した第1〜第3実施形態と実質同一の構成については同一の符号を付し、詳細な説明は省略する。また、本実施形態に係る開度規制部材及び後述する第5及び第6実施形態に係る開度規制部材は、上述した積荷排出補助ユニット1,101,201において、開度規制部材4に代えて用いることができることは言うまでもない。
[Fourth Embodiment]
Next, the opening degree regulating member according to the fourth embodiment of the present invention will be described. In the following embodiments, the same reference numerals are given to substantially the same configurations as those in the first to third embodiments described above, and detailed description thereof is omitted. Moreover, the opening degree regulating member according to the present embodiment and the opening degree regulating members according to fifth and sixth embodiments to be described later are replaced with the opening degree regulating member 4 in the above-described load discharge assisting unit 1, 101, 201. It goes without saying that it can be used.

図10及び図11を参照して、図示の開度規制部材4Aは、抜止手段を備える点で上述した開度規制部材4と異なる。より具体的に、本実施形態における抜止手段は、当接部42bAに対して上下方向へ位置調整可能に装着された抜止部材71により構成され、当接部42bAには、当接部42bAの長手方向に延びる長孔Haが当接部42bAを貫通して設けられている。抜止部材71は例えばアングル金具から構成され、下向き略L字状の断面形状を有し、当接部42bAに当接する垂下部71aと、垂下部71aの上端から略直角に延びる抜止部71bとを有する。垂下部71aには垂下部71aをその厚み方向に貫通する開口部71cが形成されている。このように構成された抜止部材71は、ボルト72と、ワッシャ73と、ナット74とを用いて当接部42bAへ取り付けられる。即ち、ワッシャ73と、抜止部材71の開口部71cと、当接部42bAの長孔Haとに挿通させたボルト72の先端をナット74に螺着させることで、抜止部材71は当接部42bAに装着される。ボルト72をナット74に強固に締め付けると、抜止部材71は当接部42bAに対して固定され、ボルト72のナット74への締め付けを緩めると、抜止部材71は長孔Haに沿って上下方向へ移動可能とされる。   Referring to FIGS. 10 and 11, the illustrated opening restriction member 4 </ b> A is different from the opening restriction member 4 described above in that it includes a retaining means. More specifically, the retaining means in the present embodiment is configured by a retaining member 71 that is mounted on the abutting portion 42bA so that the position of the abutting portion 42bA can be adjusted in the vertical direction. The abutting portion 42bA includes a longitudinal portion of the abutting portion 42bA. A long hole Ha extending in the direction is provided through the contact portion 42bA. The retaining member 71 is made of, for example, an angle bracket, has a downward substantially L-shaped cross-sectional shape, and includes a hanging portion 71a that abuts against the abutting portion 42bA and a retaining portion 71b that extends substantially at right angles from the upper end of the hanging portion 71a. Have. The hanging portion 71a has an opening 71c that penetrates the hanging portion 71a in the thickness direction. The retaining member 71 configured as described above is attached to the abutting portion 42bA using a bolt 72, a washer 73, and a nut 74. That is, the retaining member 71 is screwed into the nut 74 by screwing the tip of the bolt 72 inserted through the washer 73, the opening 71c of the retaining member 71, and the long hole Ha of the abutting portion 42bA. It is attached to. When the bolt 72 is firmly tightened to the nut 74, the retaining member 71 is fixed to the abutting portion 42bA, and when the bolt 72 is tightened to the nut 74, the retaining member 71 moves vertically along the long hole Ha. It can be moved.

このように構成された開度規制部材4Aは、次のようにして用いることができる。まず、抜止部材71を長孔Haの下方位置に合わせた状態で、開度規制部材4Aを水平状態に保たれた荷台9の後端部に上述のようにして設置する。次に、荷台9を後方へ傾斜させてアオリ板92を開き、アオリ板92の内側上端部及び外側下端部を開度規制部材4Aの第2当接部42a及び当接部42bAにそれぞれ当接させる。この状態で抜止部材71を上方へ移動させ、図12に示す様に、抜止部材71の抜止部71bをアオリ板92の下端部に当接させて位置決めする。ボルト72をナット74に対して強固に締め付けて、抜止部材71を固定する。   The opening degree regulating member 4A configured as described above can be used as follows. First, in a state where the retaining member 71 is aligned with the position below the long hole Ha, the opening degree regulating member 4A is installed at the rear end portion of the cargo bed 9 maintained in a horizontal state as described above. Next, the loading platform 9 is inclined rearward to open the tilt plate 92, and the inner upper end and the outer lower end of the tilt plate 92 are brought into contact with the second contact portion 42a and the contact portion 42bA of the opening degree regulating member 4A, respectively. Let In this state, the retaining member 71 is moved upward, and the retaining portion 71b of the retaining member 71 is brought into contact with the lower end portion of the tilt plate 92 as shown in FIG. The bolt 72 is firmly tightened against the nut 74 to fix the retaining member 71.

これにより、荷台9の傾斜角度が増大しても、当接部42bAひいては開度規制部材4A全体がアオリ板92から浮き上がるのを防止できる。よって、開度規制部材4Aが誤ってアオリ板92から外れてしまうのを防止でき、積荷排出補助ユニットを安全に用いることができる。   Thereby, even if the inclination angle of the loading platform 9 increases, it is possible to prevent the contact portion 42bA and thus the entire opening regulating member 4A from being lifted from the tilt plate 92. Therefore, the opening degree regulating member 4A can be prevented from being accidentally detached from the tilt plate 92, and the load discharge assisting unit can be used safely.

ここで、抜止手段としては、上述した形態に限定されず、例えば次の様に構成してもよい。図13を参照して、開度規制部材4Bの当接部42bBには複数の挿通孔Hbが形成され、何れか1の挿通孔Hbに抜止手段としてのボルト75を挿通させる。このように挿通されたボルト75は、その先端部がアオリ板92の下端部に当接し、当接部42bBひいては開度規制部材4B全体がアオリ板92から浮き上がるのを防止する。また、挿通孔Hbは複数個設けられているので、ボルト75を挿通させる挿通孔Hbを適宜選択することにより、上下方向におけるボルト75の位置を調整することができる。なお、挿通孔Hbに挿通する部材としては、ボルト75の他に、フラットバー等を用いることもできる。   Here, the retaining means is not limited to the above-described form, and may be configured as follows, for example. Referring to FIG. 13, a plurality of insertion holes Hb are formed in the contact portion 42bB of the opening degree regulating member 4B, and a bolt 75 as a retaining means is inserted into any one of the insertion holes Hb. The front end of the bolt 75 inserted in this way abuts against the lower end of the tilt plate 92, and the contact portion 42 b B and thus the entire opening regulating member 4 B is prevented from floating from the tilt plate 92. Since a plurality of insertion holes Hb are provided, the position of the bolt 75 in the vertical direction can be adjusted by appropriately selecting the insertion hole Hb through which the bolt 75 is inserted. In addition to the bolt 75, a flat bar or the like can be used as a member inserted through the insertion hole Hb.

或いは、図14に示す様に、当接部42bの下端部からベース部41に向けて延出する延出部42dを抜止手段として設けてもよい。このような構成によっても、延出部42dがアオリ板92の下端部に当接して、開度規制部材4Cがアオリ板92から外れるのを防止できる。   Alternatively, as illustrated in FIG. 14, an extension portion 42 d that extends from the lower end portion of the contact portion 42 b toward the base portion 41 may be provided as a retaining means. Even with such a configuration, it is possible to prevent the opening restricting member 4 </ b> C from coming off the tilt plate 92 due to the extension 42 d contacting the lower end of the tilt plate 92.

更に、図15に示す様に、当接部42bDの内面下方部位に楔型の切欠き部42eを1又は複数個(図15の例では2個)形成してもよい。このような構成によっても、仮に開度規制部材4Dがアオリ板92に対して浮き上がろうとしても、開度規制部材4Dの切欠き部42eの内面が抜止手段として機能し、アオリ板92の下端部或いは底面に当接して開度規制部材4Dがアオリ板92から外れるのを防止できる。   Furthermore, as shown in FIG. 15, one or a plurality of wedge-shaped notches 42 e (two in the example of FIG. 15) may be formed in the lower portion of the inner surface of the contact portion 42 b D. Even with such a configuration, even if the opening degree regulating member 4D tries to float up with respect to the tilting plate 92, the inner surface of the notch 42e of the opening degree regulating member 4D functions as a retaining means. It is possible to prevent the opening degree regulating member 4 </ b> D from coming off the tilt plate 92 in contact with the lower end portion or the bottom surface.

[第5実施形態]
次に、本発明の第5実施形態に係る開度規制部材について説明する。図16を参照して、図示の開度規制部材4Eは、荷台9の底板93に載置されて第1当接部として機能する支持部材(ベース部)43と、支持部材43に支持された鉤状部材44と、を備える。支持部材43は平板状に形成され、その上面には一対のブラケット43aが立設されている。鉤状部材44は側面視略下向き略コ字型に形成され、支持部材43から上方に延出する棒状の支持部44aと、支持部44aと実質平行に延びる棒状の第3当接部44bと、支持部44aの上端と第3当接部44bの上端とを接続する棒状の接続部44cとを備える。支持部44aの下端は一対のブラケット43aに挿通された支持軸43bを介して支持部材43に取り付けられ、支持軸43bを中心に鉤状部材44全体が回動自在とされている。また、鉤状部材44には、接続部44cの下面から下方に延出する第2当接部44dが設けられている。この第2当接部44dは、支持部44aと第3当接部44bの間であって、やや第3当接部44b寄りの位置に設けられ、第3当接部44bと実質上平行に延びている。
[Fifth Embodiment]
Next, an opening restriction member according to a fifth embodiment of the present invention will be described. With reference to FIG. 16, the opening degree regulating member 4 </ b> E shown in the figure is supported by a support member (base portion) 43 that is placed on the bottom plate 93 of the loading platform 9 and functions as a first contact portion, and the support member 43. And a hook-shaped member 44. The support member 43 is formed in a flat plate shape, and a pair of brackets 43a are erected on the upper surface thereof. The hook-shaped member 44 is formed in a substantially U-shape substantially downward in a side view, a rod-shaped support portion 44a extending upward from the support member 43, and a rod-shaped third contact portion 44b extending substantially parallel to the support portion 44a. And a rod-shaped connection portion 44c that connects the upper end of the support portion 44a and the upper end of the third contact portion 44b. The lower end of the support portion 44a is attached to the support member 43 via a support shaft 43b inserted through the pair of brackets 43a, and the entire hook-shaped member 44 is rotatable around the support shaft 43b. Further, the flange-shaped member 44 is provided with a second contact portion 44d extending downward from the lower surface of the connection portion 44c.

Next, an opening restriction member according to a sixth embodiment of the present invention will be described. Referring to FIG. 17, the opening degree regulating member 4 </ b> F shown in the figure includes a support member 45 placed on the bottom plate 93 of the loading platform 9, and a hook-like member 46 connected to the support member 45. The support member 45 is formed in a substantially L shape in a side view, extends in a horizontal direction in a straight line, and functions as a first contact portion, and substantially upwards from one end of the base portion 45a. It has the 2nd contact part 45b extended perpendicularly. On the other hand, the hook-shaped member 46 includes a third contact portion 46a extending in the vertical direction, an attachment portion 46b extending substantially parallel to the third contact portion 46a, and a lower end portion of the third contact portion 46a and the attachment portion 46b. And a connecting portion 46c for connecting the lower end portion.

また、支持部材45と鉤状部材46とは、連結手段により相互に連結可能とされている。本実施形態においては、支持部材45の第2当接部45bには複数の挿通孔45cが形成され、また鉤状部材46の取付部46bには複数の挿通孔46dが形成され、何れかの挿通孔45c及び挿通孔46dに挿通させたボルト47をナット48に螺着させることで、支持部材45と鉤状部材46とが連結される。   Further, the support member 45 and the hook-shaped member 46 can be connected to each other by connecting means. In the present embodiment, a plurality of insertion holes 45c are formed in the second contact portion 45b of the support member 45, and a plurality of insertion holes 46d are formed in the mounting portion 46b of the bowl-shaped member 46. The bolt 47 inserted through the insertion hole 45c and the insertion hole 46d is screwed to the nut 48, whereby the support member 45 and the hook-like member 46 are connected.

このように構成された開度規制部材4Fは次の様にして用いられる。まず、支持部材45と鉤状部材46とが分解された状態で、支持部材45のみを荷台9に設置する。このとき、ベース部45aの底面が底板93に当接し、第2当接部45bがアオリ板92の内面に沿って上方に延びるようにする。次に、図18(a)に示す様に、荷台9を僅かに傾斜させ、アオリ板92を少しだけ開く。図18(b)に示す様に、第3当接部46aと取付部46bとの間にアオリ板92が介在するように、鉤状部材46の取付部46bをアオリ板92と荷台9の底板93の間へ下方から挿入し、連結手段としてのボルト47を用いて取付部46を支持部材45の第2当接部45bに連結させる。   The opening degree regulating member 4F configured in this way is used as follows. First, in a state where the support member 45 and the bowl-shaped member 46 are disassembled, only the support member 45 is installed on the loading platform 9. At this time, the bottom surface of the base portion 45 a contacts the bottom plate 93, and the second contact portion 45 b extends upward along the inner surface of the tilt plate 92. Next, as shown in FIG. 18A, the loading platform 9 is slightly inclined and the tilt plate 92 is slightly opened. As shown in FIG. 18 (b), the mounting portion 46b of the bowl-shaped member 46 is placed on the bottom plate 92 and the bottom plate of the loading platform 9 so that the tilting plate 92 is interposed between the third contact portion 46a and the mounting portion 46b. The mounting portion 46 is connected to the second contact portion 45 b of the support member 45 using a bolt 47 as a connecting means.

これにより、荷台9を更に傾斜させた場合であっても、アオリ板92の内側上端部及び外側下端部は開度規制部材4Fの第2当接部45b及び第3当接部46aにそれぞれ当接することとなり、アオリ板92の開度を規制できる。また、開度規制部材4Fがアオリ板92から浮き上がっても、連結部46cがアオリ板92の下端部に当接することで開度規制部材4Fがアオリ板92から外れるのを防止でき、連結部46cは抜止手段として機能する。   As a result, even when the loading platform 9 is further inclined, the inner upper end and the outer lower end of the tilt plate 92 respectively contact the second contact portion 45b and the third contact portion 46a of the opening restriction member 4F. The opening of the tilt plate 92 can be regulated. Further, even when the opening degree regulating member 4F is lifted from the tilt plate 92, it is possible to prevent the opening degree regulating member 4F from coming off the tilt plate 92 by the contact of the connecting portion 46c with the lower end portion of the tilt plate 92, and the connecting portion 46c. Functions as a retaining means.

なお、本実施形態においては、支持部材45の第2当接部45bと鉤状部材46の第3当接部46bとを連結させる連結手段としてボルト47を用いたが、例えば第2当接部45bに係合突部を設け、これを取付部46bの挿通孔46dに挿通させて両者を連結させてもよく、或いは取付部46bに係合突部を設け、これを第2当接部45bの挿通孔45cに挿通させて両者を連結させてもよい。   In the present embodiment, the bolt 47 is used as a connecting means for connecting the second contact portion 45b of the support member 45 and the third contact portion 46b of the bowl-shaped member 46. For example, the second contact portion 45b may be provided with an engaging projection, which may be inserted into the insertion hole 46d of the mounting portion 46b to connect them, or the mounting portion 46b may be provided with an engaging projection, which is connected to the second contact portion 45b. Both of them may be connected by being inserted through the insertion hole 45c.

[第7実施形態]
次に、第7実施形態に係る開度規制部材について説明する。なお、上述した第1〜第6実施形態に係る積荷排出補助ユニットと実質同一の構成については同一の符号を付し、詳細な説明は省略する。
[Seventh Embodiment]
Next, the opening degree regulating member according to the seventh embodiment will be described. In addition, about the structure substantially the same as the load discharge auxiliary | assistance unit which concerns on 1st-6th embodiment mentioned above, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

図19を参照して、この開度規制部材4Mは、上述したガイド部材2に規制部材42Mが一体的に設けられて構成されており、荷台9の内部空間を積載空間S1と非積載空間S2とへ区画する区画手段としての機能をも備えるものである。より具体的に、開度規制部材4Mは、上述したガイド部材2を備えると共に、規制部材42Mの連結部42cがガイド部材2の後端部上方から後方へ延びるように設けられ、当接部42bが連結部42cの後端部から下方に延出するように設けられている。当該構成においては、ガイド部材2の底面(ガイド部材2の底板22b)が荷台9の底板93に当接する第1当接部として機能し、ガイド部材2の後端面(後板22c)が第2当接部として機能し、規制部材42Mの当接部42bが第3当接部として機能する。即ち、荷台9が後方へ傾斜すると、ガイド部材2の底面(第1当接部)が荷台9の底面に当接し、ガイド部材2の後端面(第2当接部)がアオリ板92の内面上端部に当接し、当接部42b(第3当接部)がアオリ板92の外面下端部に当接することで、アオリ板92の開度が規制される。   Referring to FIG. 19, the opening degree regulating member 4M is configured by integrally providing a regulating member 42M on the guide member 2 described above, and the internal space of the loading platform 9 is divided into a loading space S1 and a non-loading space S2. It also has a function as partitioning means for partitioning. More specifically, the opening degree regulating member 4M includes the above-described guide member 2, and the connecting portion 42c of the regulating member 42M is provided so as to extend rearward from above the rear end portion of the guide member 2, and the contact portion 42b. Is provided so as to extend downward from the rear end of the connecting portion 42c. In this configuration, the bottom surface of the guide member 2 (the bottom plate 22b of the guide member 2) functions as a first contact portion that contacts the bottom plate 93 of the loading platform 9, and the rear end surface (rear plate 22c) of the guide member 2 is the second. It functions as a contact part, and the contact part 42b of the regulating member 42M functions as a third contact part. That is, when the loading platform 9 is inclined rearward, the bottom surface (first contact portion) of the guide member 2 contacts the bottom surface of the loading platform 9, and the rear end surface (second contact portion) of the guide member 2 is the inner surface of the tilt plate 92. The opening degree of the tilt plate 92 is regulated by contacting the upper end portion and the contact portion 42b (third contact portion) contacting the lower end portion of the outer surface of the tilt plate 92.

かかる構成によれば、また、ガイド部材2の底面全体が荷台9の底板93と当接するので、荷台9を後方へ傾斜させた際における開度規制部材4Mの安定性を向上できる。また、ガイド部材と開度規制部材とを個別に設置する必要がなく、開度規制部材4Mを設置するだけで足りるので、作業性を向上できる。   According to such a configuration, the entire bottom surface of the guide member 2 is in contact with the bottom plate 93 of the loading platform 9, so that the stability of the opening degree regulating member 4M when the loading platform 9 is inclined rearward can be improved. In addition, it is not necessary to install the guide member and the opening degree regulating member separately, and it is sufficient to install the opening degree regulating member 4M. Therefore, workability can be improved.

[第8実施形態]
次に、本実施形態に係る開度規制部材4Nについて説明する。図20及び図21を参照して、本実施形態に係る開度規制部材4Nは、例えば平板状に形成されたガイド部材202と、ガイド部材202に着脱自在に連結される規制部材240と、を備える。ガイド部材202は、一対の幅広面を有し、一方の幅広面が非積載空間S1に面するように配置され、この幅広面がガイド面21aとして機能する。ガイド部材202の前端近傍位置にはガイド部材202を高さ方向に貫通する貫通孔H5が形成されており、この貫通孔H5に係合部材23の一端部が挿入される。また、ガイド部材202の後端近傍位置にはガイド部材202を高さ方向に貫通する貫通孔H6が形成されており、この貫通孔H6に規制部材240が挿入されてガイド部材202と連結される。
[Eighth Embodiment]
Next, the opening degree regulating member 4N according to this embodiment will be described. Referring to FIGS. 20 and 21, the opening degree regulating member 4N according to the present embodiment includes, for example, a guide member 202 formed in a flat plate shape, and a regulating member 240 detachably connected to the guide member 202. Prepare. The guide member 202 has a pair of wide surfaces, and is arranged so that one wide surface faces the non-loading space S1, and this wide surface functions as the guide surface 21a. A through hole H5 penetrating the guide member 202 in the height direction is formed in the vicinity of the front end of the guide member 202, and one end of the engaging member 23 is inserted into the through hole H5. Further, a through hole H6 penetrating the guide member 202 in the height direction is formed in the vicinity of the rear end of the guide member 202, and a regulating member 240 is inserted into the through hole H6 and connected to the guide member 202. .

規制部材240は下向略U字状に形成されており、挿入部242aの上端と当接部242bの上端とが連結部242cにより接続された形状とされている。また、挿入部242aの上端寄り部位にはフランジ部242fが設けられている。フランジ部242fの外径は、ガイド部材202の貫通孔H6の内径よりも大径とされている。かかる構成において、規制部材240の挿入部242aをガイド部材202の貫通孔H6に挿入すると、フランジ部242fがガイド部材202の上端面202aに当接し、規制部材240の連結部242cがガイド部材202の上端面202aよりも幾分(例えば5cm程度)上方にするようになる。これにより、荷台9を傾斜させてアオリ板92を開く際に、アオリ板92の上端が規制部材240の連結部242cに衝突するのを阻止できる。   The restricting member 240 is formed in a substantially downward U shape, and has a shape in which the upper end of the insertion portion 242a and the upper end of the contact portion 242b are connected by the connecting portion 242c. Further, a flange portion 242f is provided near the upper end of the insertion portion 242a. The outer diameter of the flange portion 242f is larger than the inner diameter of the through hole H6 of the guide member 202. In this configuration, when the insertion portion 242a of the restriction member 240 is inserted into the through hole H6 of the guide member 202, the flange portion 242f abuts on the upper end surface 202a of the guide member 202, and the connecting portion 242c of the restriction member 240 is the guide member 202. It is somewhat above the upper end surface 202a (for example, about 5 cm). Accordingly, when the tilting plate 92 is opened by tilting the loading platform 9, the upper end of the tilting plate 92 can be prevented from colliding with the connecting portion 242 c of the regulating member 240.

このように構成された開度規制部材4Nは次の様にして用いられる。まず、規制部材240が取り外された状態で、ガイド部材202を上述したガイド部材2と同様の手順で荷台9に設置し、荷台9の積載空間S1に砂や砂利等の積荷を積載して目的地へ運搬する。目的地に到達後、ガイド部材202の貫通孔H6に規制部材240の挿入部242aを挿入する。このとき、図20に示す様に、規制部材240の当接部242bがアオリ板92の外側に位置する、即ちアオリ板92を介してガイド部材202の後端面222cに対向するようにする。そして、所望の運搬具を所定位置に配置した後に、荷台9を後方へ傾斜させて、上述したのと同様に積荷を排出させればよい。   The opening degree regulating member 4N configured in this way is used as follows. First, with the regulating member 240 removed, the guide member 202 is installed on the loading platform 9 in the same procedure as the guide member 2 described above, and a load such as sand or gravel is loaded on the loading space S1 of the loading platform 9. Transport to the ground. After reaching the destination, the insertion portion 242a of the restricting member 240 is inserted into the through hole H6 of the guide member 202. At this time, as shown in FIG. 20, the contact portion 242 b of the regulating member 240 is positioned outside the tilt plate 92, that is, is opposed to the rear end surface 222 c of the guide member 202 through the tilt plate 92. And after arrange | positioning a desired transporter in a predetermined position, the loading platform 9 may be inclined back and a load may be discharged similarly to what was mentioned above.

このとき、ガイド部材202の底面222bが荷台9の底板93と当接する第1当接部として機能し、ガイド部材202の後端面222cがアオリ板92の内側上端部に当接する第2当接部として機能し、規制部材240の当接部242bがアオリ板92の外側下端部に当接する第3当接部として機能する。   At this time, the bottom surface 222 b of the guide member 202 functions as a first contact portion that contacts the bottom plate 93 of the loading platform 9, and the rear end surface 222 c of the guide member 202 contacts the inner upper end portion of the tilt plate 92. And the contact portion 242b of the regulating member 240 functions as a third contact portion that contacts the outer lower end of the tilt plate 92.

このように、本実施形態の開度規制部材4Nによれば、規制部材240をガイド部材202から取り外すことができるので、規制部材240が荷台9からはみ出した状態でダンプカーDを走行させる必要がなく、走行時における安全性を確保できる。また、規制部材240の挿入部242aをガイド部材202の貫通孔H6へ挿入するだけで、規制部材240をガイド部材202へ装着(連結)でき、使い勝手がよい。更に、ガイド部材202の底面222b全体が荷台9の底板93と当接するので、荷台9を後方へ傾斜させた際における開度規制部材4Nの安定性を向上できる。   Thus, according to the opening degree regulating member 4N of the present embodiment, since the regulating member 240 can be removed from the guide member 202, there is no need to run the dump truck D with the regulating member 240 protruding from the loading platform 9. , Safety during driving can be ensured. In addition, the restriction member 240 can be mounted (connected) to the guide member 202 simply by inserting the insertion portion 242a of the restriction member 240 into the through hole H6 of the guide member 202, which is convenient. Furthermore, since the entire bottom surface 222b of the guide member 202 is in contact with the bottom plate 93 of the loading platform 9, the stability of the opening degree regulating member 4N when the loading platform 9 is tilted rearward can be improved.

また、貫通孔H6に挿入された規制部材240はガイド部材202に対して旋回自在であるため、平面視におけるガイド部材202に対する規制部材240の角度を自在に変えることができる。よって、荷台9に設置されるガイド部材202の傾斜角度、ひいては排出口Pの左右幅を自由に設定することができる。   Further, since the regulating member 240 inserted into the through hole H6 is rotatable with respect to the guide member 202, the angle of the regulating member 240 with respect to the guide member 202 in plan view can be freely changed. Therefore, it is possible to freely set the inclination angle of the guide member 202 installed on the loading platform 9 and thus the left and right width of the discharge port P.

更に、貫通孔H5及び貫通孔H6はガイド部材202の縦方向に貫通して設けられているので、ガイド部材202を上下反転させ、係合部材23及び規制部材240を貫通孔H5及びH6へ挿入すれば、ガイド部材202の他方の幅広面をガイド面21aとして用いることができる。このように使用することにより、積荷の排出箇所を荷台9の左寄り部位(図20に示す状態)から、右寄り部位へ変えることができ、作業場の地形等の条件に応じた形態での使用が可能となる。   Further, since the through hole H5 and the through hole H6 are provided so as to penetrate in the vertical direction of the guide member 202, the guide member 202 is turned upside down and the engaging member 23 and the regulating member 240 are inserted into the through holes H5 and H6. Then, the other wide surface of the guide member 202 can be used as the guide surface 21a. By using in this way, the discharge point of the load can be changed from the left part of the loading platform 9 (the state shown in FIG. 20) to the right part, and it can be used in a form according to the conditions such as the topography of the workplace. It becomes.

なお、規制部材240の挿入部242aの下端からフランジ部242fまでの長さL5は、ガイド部材202の上下方向長さL6と実質同一とするのが好ましい。長さL5が長さL6よりも極端に短いと、規制部材240のガイド部材202への連結が不安定になるためである。また、ガイド部材202の寸法(高さ寸法等)は上述したガイド部材2の寸法と同様に設定されるのが好ましい。   Note that the length L5 from the lower end of the insertion portion 242a of the restricting member 240 to the flange portion 242f is preferably substantially the same as the vertical length L6 of the guide member 202. This is because if the length L5 is extremely shorter than the length L6, the connection of the regulating member 240 to the guide member 202 becomes unstable. Moreover, it is preferable that the dimension (height dimension etc.) of the guide member 202 is set similarly to the dimension of the guide member 2 mentioned above.

以上、本発明の実施形態に係る積荷排出補助ユニット及び開度規制部材について添付の図面を参照して説明したが、本発明はかかる実施形態に限定されず、本発明の範囲を逸脱することなく種々の変形乃至修正が可能である。   As mentioned above, although the load discharge auxiliary | assistance unit and opening degree control member which concern on embodiment of this invention were demonstrated with reference to attached drawing, this invention is not limited to this embodiment, and does not deviate from the scope of the present invention.

The shape of the guide member 2 is not limited to a box shape, and the guide member may be formed from a single plate-like member, for example.

上記実施形態におけるガイド部材2(図3)は、ベース板21と、ベース板21の周縁から側方へ延出する4枚の側板22とを備えて構成されたが、本発明はこれに限定されず、例えば図22に示すガイド部材2Aのように、複数の角パイプで矩形状の外枠22Aを形成し、その片面にベース板21を溶接等により固定させると共に、外枠22Aの内側に複数(図22の例では3本)の角パイプを補強部材22Bとして配設させて構成してもよい。このように構成することにより、ガイド部材2Aの軽量化を図りつつ、ガイド部材2A全体の強度を上げることができる。   The guide member 2 (FIG. 3) in the above embodiment includes the base plate 21 and the four side plates 22 that extend laterally from the periphery of the base plate 21, but the present invention is limited to this. For example, as in the guide member 2A shown in FIG. 22, a rectangular outer frame 22A is formed by a plurality of square pipes, the base plate 21 is fixed to one surface thereof by welding or the like, and the inner side of the outer frame 22A is fixed. A plurality (three in the example of FIG. 22) of square pipes may be arranged as the reinforcing member 22B. By comprising in this way, the intensity | strength of the guide member 2A whole can be raised, aiming at weight reduction of the guide member 2A.

さらに、図22に示す様に、開口部Hに隣接させて他の開口部Hcを設けてもよい。このように構成することで、係合部材23の他端部を開口部Hcに挿通させて係合部材23を収納することができる。   Furthermore, as shown in FIG. 22, another opening Hc may be provided adjacent to the opening H. By configuring in this way, the engaging member 23 can be accommodated by inserting the other end of the engaging member 23 through the opening Hc.

更に、図23に示す様に、第2当接部42aの上端部が当接部42bの上端部に固定された側面視略逆向V字状の鉤状部42Gを有する開度規制部材4Gを用いることもできる。また、このように構成された開度規制部材4Gに、上述したような抜止手段(抜止部材71、ボルト75、延出部42d、切欠き部42e)を設けてもよい。開度規制部材4(4A〜4D)のベース部41は平板状である必要はなく、例えば棒状とすることもでき、開度規制部材4(4A〜4D)の第2当接部42a、当接部42b(42bA、42bD)、連結部42c等は棒状に限定されず、平板状であってもよい。   Further, as shown in FIG. 23, an opening degree regulating member 4G having a hook portion 42G having a substantially reverse V-shape in a side view in which the upper end portion of the second contact portion 42a is fixed to the upper end portion of the contact portion 42b. It can also be used.
