摘要： An apparatus for controlling the posture of the work implement of a loader comprises a boom supported by a boom pivot on a mast secured to a vehicle body and movable upward and downward by a boom cylinder, first and second arms supported by an intermediate portion of the boom and pivotally movable relative to each other, a pivotal member pivoted to the boom by the boom pivot, a first connecting member operatively connecting a point on the pivotal member away from the pivoted point thereof to the first arm, a second connecting member connecting the second arm to the work implement at the forward boom end, an engaging portion for engaging the second arm with the first arm when the implement is moved by an implement cylinder in the scooping direction approximately into a specified posture, and an interlocking member operatively connecting the pivotal member to an implement control valve for the implement cylinder so that the valve is operated in the dumping direction by the movement of the pivotal member with the rise of the boom after the second arm is engaged with the first arm by the engaging portion. The implement can be maintained in the specified posture when the boom is raised, preventing earth from spilling from the implement.

摘要： A mark sensor device which is small and convenient in mounting is disclosed. The mark sensor device contains an image data transmitter made of a plurality of optical fibers in a bundle positioned between the object mark and the image sensor, and uses a one-dimensional image sensor. The ends of the plurality of optical fibers on one end of the image data transmitter are arranged in a square shape. The other ends of the plurality of optical fibers on the other end of the image data transmitter are arranged along a line. The one-dimensional image sensor is aligned correspondingly with the linearly aligned ends of the plurality of optical fibers. Accordingly, the light including the optical image of the object mark irradiates the one end of the image data transmitter, travels through the transmitter and comes out from the other end of the transmitter. Thus, the brightness of the light is detected by the one-dimensional image sensor for accurate positioning of the object mark.
摘要翻译：公开了一种安装方便小的标记传感器装置。标记传感器装置包含由位于物体标记和图像传感器之间的束中的多根光纤制成的图像数据发送器，并使用一维图像传感器。图像数据发送器的一端上的多根光纤的端部排列成正方形。图像数据发送器的另一端的多根光纤的另一端沿着一条线排列。一维图像传感器对应于多根光纤的直线对齐端。因此，包括物体标记的光学图像的光照射图像数据发送器的一端，通过发送器行进，并从发送器的另一端出来。因此，通过一维图像传感器检测光的亮度，以准确定位物体标记。

摘要： A work vehicle includes a pair of, right and left booms detachably attached to a vehicle body, an implement attached to leading ends of the booms and a stand for supporting the booms with the implement being placed on a ground surface when the booms are detached from the vehicle body. The stand includes a pair of, right and left stand members provided in correspondence with the right and left booms and a stand connecting member for interconnecting the stand members. Each stand member is attached to the boom corresponding thereto in such a manner that the stand is movable between a use position in which each stand member projects downwardly from the boom for supporting the boom and a non-use position in which each stand member extends along the boom.
摘要翻译：工作车辆包括一对可拆卸地附接到车身上的左右起重臂，附接到起重臂的前端的工具和用于支撑悬臂的支架，当工具被拆卸时，工具被放置在地面上车体。该支架包括一对左右支架和一对左右支架，以及用于互连支架部件的支架连接部件。每个支架构件以这样的方式附接到与其对应的起重臂，使得支架可在使用位置之间移动，其中每个支架构件从用于支撑悬臂的起重臂向下突出的使用位置和每个支架构件沿其延伸的不使用位置繁荣。
