Four-cylinder closed hydraulic bucket for rotary excavating pile machine
The invention relates to a four-cylinder closed hydraulic bucket for a rotary excavating pile machine. The four-cylinder closed hydraulic bucket can drill and excavate a hole and can also be used for a continuous wall excavating project. The problem that when a known hydraulic bucket for the rotary excavating pile machine meets some hard operation layers, two bucket bodies cannot be closed in place and cannot be lifted and unload soil is mainly solved. A stretchable drill rod is inserted into a sleeve groove of a tooth disc occluder to be connected through a plug pin, and the lower end of the tooth disc occluder is connected with a stand column. Two bucket bodies are connected to two bucket hinge shafts at the lower end of the stand column respectively. The upper ends of four hydraulic oil cylinders are connected to four oil cylinder hinge shafts on the stand column respectively, and the lower ends of the four hydraulic oil cylinders are connected to four oil cylinder connecting shafts on the two bucket bodies respectively. The four-cylinder closed hydraulic bucket is good in operation guidance, the perpendicularity of the stretchable drill rod is high, the included angle between the guiding lines of the four hydraulic oil cylinders and the vertical line of the stretchable drill rod is large, the formed closing force of the bucket bodies is large, and the four-cylinder closed hydraulic bucket is convenient to assemble and disassemble.
