Excavator hydraulic type thumb clamp mechanism and excavator work device
The invention discloses an excavator hydraulic type thumb clamp mechanism and an excavator work device. The excavator hydraulic type thumb clamp mechanism is characterized by comprising a single connecting rod, a left rocker, a right rocker, an oil cylinder and a thumb clamp. The thumb clamp, the single connecting rod, the left rocker and the right rocker are connected through pin shafts to form a four-bar mechanism. The reciprocated movement of the thumb clamp is achieved by hydraulically driving the hydraulic oil cylinder, and the grabbing action is formed through the thumb clamp and a shovel. The grabbing operation can be finished in cooperation with the shovel only by assembling the thumb clamp mechanism, and when the grabbing operation is not needed, the thumb clamp mechanism can be folded while the normal excavation operation cannot be affected; and therefore a large amount of machine tool disassembling and assembling time is saved, the universality and flexibility of an excavator are improved, cost is low, and refitting is convenient.
