Single-cylinder-driven mechanical grab bucket and operation machine
The invention provides a single-cylinder-driven mechanical grab bucket and an operation machine. The grab bucket comprises a plurality of claw bodies which are connected to the same driving cylinder and evenly arranged in the circumferential direction of the driving cylinder, and the driving cylinder can drive the claw bodies to be synchronously opened or closed through telescopic motion; and limiting mechanisms connected between the driving cylinder and the claw bodies. According to the grab bucket, the claw bodies can synchronously rotate relative to the axial extension line of the driving cylinder in the opening or closing process through the limiting mechanisms, and the opening angles and the closing angles of the claw bodies are synchronously limited, so that it is guaranteed that the driving cylinder can control the claw bodies to be opened and closed synchronously in the stretching and retracting process. In addition, the axial extension line of the driving cylinder is used as the center line of the claw bodies in the opening and closing process, so that each claw body is prevented from deflecting in the opening and closing process, the accurate grabbing position of the grab bucket is ensured, the grabbing force is optimized, the overall stress of the grab bucket is simplified, and the structural stability of the grab bucket is improved.
本发明提供一种单缸驱动机械式抓斗及作业机械。该抓斗包括：若干个爪体，分别连接于同一驱动缸，并沿驱动缸的周向均匀设置，驱动缸通过伸缩运动能驱动各个爪体同步的打开或闭合；限位机构，连接于驱动缸与各个爪体之间。该抓斗利用限位机构使各个爪体在打开或闭合的过程中能相对于驱动缸的轴向延长线同步转动，并对各个爪体的打开角度和闭合角度分别进行同步限位，从而保证驱动缸在伸缩过程中能够控制各个爪体的开闭同步进行，并且以驱动缸的轴向延长线作为各个爪体开合过程中的中心线，从而避免出现各个爪体在开合过程中发生偏转，保证抓斗的抓取位置准确、抓取力最优化、简化抓斗的整体受力，提高抓斗结构稳定性。
