The invention relates to a rock breaking device, belongs to the technical field of engineering equipment, and solves the technical problem that related parts, connected with an oil cylinder, of a rock breaking device in the prior art are frequently damaged. The rock breaking device comprises a small arm, a scarifier and a first oil cylinder, the scarifier is hinged to the small arm, the two ends of the first oil cylinder are hinged to the small arm and the scarifier respectively, the rock breaking device is characterized in that a through hole is formed in the hinged position of the small arm and/or the scarifier and the first oil cylinder, a connecting block is movably arranged in the through hole, an elastic piece is connected to a position between the hole wall of the through hole and the connecting block, the first oil cylinder is hinged to the connecting block, when the first oil cylinder extends out, the connecting block is abutted with the hole wall of the through hole under the action of the elastic force of the elastic piece, and when the first oil cylinder is tightened, the connecting block overcomes the elastic force of the elastic piece to be separated from the hole wall of the through hole under the action of the recovery force of the first oil cylinder. According to the rock breaking device, the probability that the first oil cylinder and parts connected with the first oil cylinder are damaged is lower.
本发明涉及一种破岩装置，属于工程设备技术领域，解决了相关技术中的破岩装置存在与油缸相接的相关部件经常损坏的技术问题。该破岩装置包括小臂、松土器和第一油缸，松土器铰接在小臂上，第一油缸的两端分别与小臂和松土器铰接，其特征在于：小臂和/或松土器与第一油缸的铰接部位开设有通孔，通孔中活动地设置有连接块，通孔孔壁与连接块之间连接有弹性件，第一油缸铰接在连接块上；在第一油缸伸出时，连接块在弹性件弹力的作用下与通孔孔壁抵接；在第一油缸收紧时，连接块在第一油缸回收力的作用下克服弹性件的弹力而与通孔孔壁分离。该破岩装置中的第一油缸以及与第一油缸相连的部件出现损伤的几率更低。
