る。(d) Means to solve the problem In this invention, a box-shaped loading platform is installed on the top of the traveling device.
The base of the actuating arm is rotatably supported on both sides of the front half side wall on the tilting side of the loading platform via a fulcrum pin, and the rotational raising and lowering operation of the operating arm is controlled by the tilting of the loading platform. By configuring the operation arm to be performed in the side direction, the opening/closing bucket at the tip of the arm can be raised and lowered in the direction of the tilting side of the loading platform regardless of the forward tilting operation of the loading platform. is constructed so that it can be raised and lowered by a hydraulic device pivotally supported on the side wall of the loading platform, and a hydraulic cylinder is attached to the upper edge of the operating arm, and the hydraulic cylinder is interlocked with the opening/closing bucket of the loading bucket via a link mechanism. The link mechanism is such that when the opening/closing bucket is closed, the hydraulic cylinder and the rod interposed between the cylinder and the bucket are located approximately in a straight line, and the operating end of the cylinder and the connecting portion of the rod are in contact with each other. The present invention provides a power transport vehicle in which a link interposed between the arm and the arm is positioned substantially perpendicular to the above-mentioned straight line.
(ホ) 作用・効果
本考案によれば、下記のような作用及び効果を
奏することができる。(E) Functions and Effects According to the present invention, the following functions and effects can be achieved.
従来のものは、積込み用バケツトを装着する
取付アームが走行フレームに直接装着されてい

の前半部両側に枢支されているため、作動アー
ムの全体の長さを可及的に短く構成でき、強度
の向上をはかりうると共に、別途補強部材も必
要とせず簡易な構造に構成できる。 In the conventional type, the mounting arm for mounting the loading bucket was directly mounted on the traveling frame, so the overall length of the mounting arm had to be made long, and the mounting arm and the mounting device had to be made strong. However, in this invention, the operating arm base is pivoted on both sides of the front half of the loading platform, so the overall length of the operating arm can be configured as short as possible, and the strength is increased. In addition, it is possible to achieve a simple structure without requiring a separate reinforcing member.
また、従来のものは、左右側の取付アームの
間隔を広くとらざらるを得ず、積込みバケツト
の支持を確実、強固に行うことができなかつた
が、本考案の場合は、作動アームの取付間隔が
せまく構成されるのでバケツトの支持が確実に
行える。 In addition, with the conventional model, the distance between the left and right mounting arms had to be wide, making it impossible to securely and firmly support the loading bucket. Since the spacing is narrow, the bucket can be supported reliably.
バケツト作動用の油圧シリンダーを作動アー
ムの上側縁に装着し、リンク機構を介して積込
み用バケツトと連動連結しているので、作動ア

ず、バケツトの別個独立した回動によつて土砂
等を荷箱全体に積込みできる。 The hydraulic cylinder for operating the bucket is attached to the upper edge of the operating arm and is interlocked with the loading bucket via a link mechanism, so the actuation arm and bucket can be operated separately and independently. Even though the bucket cart is located in the front half of the cargo box when the operating arm is rotated upward, earth and sand can be loaded into the entire cargo box by rotating the bucket cart independently.
そして、全体として小型でコンパクトに構成
されると共に、積込み作業や排土作業を容易
に、かつ能率的に行うことができるものであ
る。 The overall structure is small and compact, and loading and unloading operations can be carried out easily and efficiently.

直ちに土砂の均平作業を開始することができ、
作動待ち時間が短縮されて能率向上をはかるこ
とができる。 In addition, the tilting and restoring operation of the box-shaped cargo platform and the lifting and lowering of the loading bucket can both be performed simultaneously without contacting each other. For example, while restoring the box-shaped cargo platform after dumping, the Lower the loading bucket to the forward position,
Earth and sand leveling work can be started immediately.
The waiting time for operation is shortened and efficiency can be improved.
