Excavator having cut bar auto pushing device

摘要

The present design is that the excavation operation is terminated after the original position to lift the casing and the drilling pipe and secure the rock with embedded strongly in the drilling pipes according to Sikkim lower the internal rotation cylinder piston, fast on the excavator for automatically discharging the excavated rock It has a characteristic that can be easily discharged.; The subject innovation for this is, bracket (2) is fixed a support plate (1) for connecting the arm of crane fork and; It said support plate (1) and by connecting the support hinge (5) having a wedge (6) in the bottom support columns (3) and that; Said support plate (1) and the supporting hinge (5) so that the assembly to guide one lift casing (10) connecting the rod (4) and; The guide rod (4) on both sides are supported are inserted and bearing 13 for supporting the rotary cylinder 20, which passes through the center of the top and bottom assembly for the connection which can be connected to the value of the pin 12 backward, the platform hinge (11 ) the elevating housing 10 is formed with; The elevation through the center of the casing 10 is supported by a bearing 13 a rotary cylinder, which central portion has gear 21 is held in place by a key 22 is engaged is rotated with the pinion 31 of the motor 30 ( 20); The rotation is fixed to the upper end of the cylinder 20. The rotary cylinder hydraulic pressure supply rotary joint (27) for elevating the supply and return, while the piston 23, the pressure oil into the rotating cylinder 20 rotates with 20 Wow; The rotary cylinder 20 is inserted into the rotary piston 23 rotating with the cylinder (20) and raised and lowered by the hydraulic pressure supplied to and recovered from a rotary stop, the rotary joint 27 of the cylinder 20, and; Press iron 26, which is assembled on the lower pressing the falling rock when the piston 23 of the piston 23 and the; Drilling pipe (25) in which the screw assembly rotating the cap 24 and screw assembly to the lower portion of the cylinder 20 and excavating the rock and rotate with the rotating cylinder 20 and; To ensure that the pinion (31) assembled in the holding its axis fixed to the rear rotary cylinder 20 of the elevation housing 10 is engaged with the gear 21 of the rotary cylinder 20 for rotating the rotating cylinder 20 motor 30 and; Fixed to the bottom support plate (1) it is characterized in that holding configured value platform for lifting the lifting of the casing (10).
