Bucket wheel machine trailer coupling mechanism

The utility model relates to a bucket wheel machine trailer coupling mechanism for being connected between bucket wheel machine trailer and the cart, including first ring and second ring, first ring horizontal installation is on the pendulum rod of trailer, the second ring is vertical to be installed on the cart, wherein, first ring is sealed circular ring, the second ring is non - sealed circularring and opens jaggedly at its top, first ring passes through the breach is detained the second ring. Have a great amount of dispersion to the contact between permissible cart of ring docking mechanism and the trailer, controllable scope increase makes things convenient for the separation and the butt joint of trailer, has solved the problem that readily releasable and butt joint were linked up with not to the bolt formula. 本实用新型涉及种斗轮机尾车连接机构，用于斗轮机尾车与大车之间的连接，包括第圆环和第二圆环；所述第圆环水平安装在尾车的摆杆上，所述第二圆环竖直安装在大车上，其中，所述第圆环为封闭圆环，所述第二圆环为非封闭圆环且在其顶部开有缺口，所述第圆环通过所述缺口扣入所述第二圆环。本实用新型所述圆环对接机构可以允许大车与尾车之间的对接点有较大的偏差量，可控的范围增大，方便尾车的分离与对接，解决了插销式挂钩
