Bucket body linkage type shell bucket of excavator
A bucket body linkage type shell bucket of an excavator comprises a bucket body opening and closing mechanism and a symmetrical crank sliding block mechanism. The bucket body opening and closing mechanism comprises a bucket frame, a left bucket body, a right bucket body, a first hydraulic cylinder and a second hydraulic cylinder. The left bucket body and the right bucket body are symmetrically mounted below the bucket frame through a first revolute pair and a second revolute pair respectively; one ends of the first hydraulic cylinder and the second hydraulic cylinder are respectively arranged above the bucket frame through a third revolute pair and a fourth revolute pair, and the other ends are respectively hinged with the left bucket body and the right bucket body through revolute pairs. The symmetrical crank sliding block mechanism is a plane six-rod mechanism with a sliding pair and comprises a bucket frame, a left bucket body, a right bucket body, a first left connecting rod, a first right connecting rod and a first sliding block. In order to improve the stress balance and the load capacity, the shell bucket further comprises a second left connecting rod, a second right connecting rod and a second sliding block, the assembling connection mode is the same as that of the first left connecting rod, the first right connecting rod and the first sliding block, mirror symmetry is achieved, and the rigidity and the grabbing reliability of the shell bucket are greatly improved.
一种斗体联动式挖掘机贝壳斗包含斗体启闭机构、对称曲柄滑块机构。所述斗体启闭机构包括铲斗架、左斗体、右斗体、第一液压缸、第二液压缸。所述左斗体和右斗体分别通过第一、二转动副对称安装在铲斗架下方；第一、二液压缸一端分别通过第三、四转动副安装在铲斗架上方，另一端分别通过转动副与左斗体、右斗体铰接。所述对称曲柄滑块机构为含移动副的平面六杆机构，包括铲斗架、左斗体、右斗体、第一左连杆、第一右连杆、第一滑块。为了改善受力均衡性，提高负载能力，该种贝壳斗还包括第二左连杆、第二右连杆、第二滑块，装配连接方式分别与第一左连杆、第一右连杆、第一滑块相同，并镜像对称，大幅提高了贝壳斗的刚性和抓持可靠性。
