An elastic block limiting mechanism includes: a base, a first elastic limiting assembly, a second elastic limiting assembly, a turntable and a bearing. The first elastic limiting assembly includes a first elastic member and a first elastic block. The second elastic limiting assembly includes a second elastic member and a second elastic block. The turntable includes a ring-shaped turntable body and a shifting lever. The bearing is mounted in a through hole and fixed to the base body, the turntable body being inserted into the bearing and forming a fixation to achieve a rotational connection with the base body. Compared with the related art, the elastic block limiting mechanism of the present disclosure has a simple structure, small space occupation, good stability, effective noise reduction, and high reliability.

Elastic block limiting mechanism

A regeneration control hydraulic system for an excavator, including at least one hydraulic pump, an actuator, a regeneration oil path, and a regeneration cut-off oil path. The regeneration oil path is configured to send a return oil as a regeneration oil to a cavity having a negative pressure of the actuator. The regeneration oil path is provided with a regeneration valve and a first control valve. The first control valve is configured to control the regeneration oil to enter the cavity having the negative pressure of the actuator when a working device of the excavator retracts inwards, or to control the oil to be discharged from the actuator to the regeneration cut-off oil path when the working device swings outwards. The regeneration cut-off oil path is configured to send the regeneration oil passing through the regeneration valve or the oil discharged from the actuator to other destinations.
