Abstract
The utility model discloses a dredger dipper arm rotating device. The device is that the dipper arm and a hollow rotating shaft are connected into an entire body. The hollow rotating shaft extends into the shell and is actively connected with the shell, and the hollow rotating shaft is fixed with the nut screw. A gearwheel is provided on the hollow rotating shaft, the gearwheel is tooth-jointed with a pinion, the pinion is actively connected with one end of a hydraulic motor, and the other end of the hydraulic motor is connected with the perfusion tube extending from the main machine. The perfusion tube extends into the hollow rotating shaft and is connected with the other end of the tube rotating shaft of the perfusion. The other end of the tube rotating shaft of the perfusion is connected with the perfusion tube extending from the main machine, and the tube rotating shaft of the perfusion is fixed on the shell. The utility model is used for that the dredger can synchronously dig in the form of multi-azimuth when the dredger digs, and the utility model can re-use the dipper arm to rotate, drill earth and perforate as a result of that the dipper arm can rotate and can be used as the loading.
Description
Affiliated technical field
The utility model relates to a kind of excavator boom whirligig.
Background technology
At present, known excavator boom only limits a direction to excavate, and can not multi-directional rotation excavate and load, and causes difficulty to excavation.
Summary of the invention
Can not rotate the deficiency of excavating and adorning sanction in order to overcome existing excavator boom, the utility model provides a kind of dipper of rotation, and this dipper can not only rotate and excavate and adorn and cut out, and can also utilize the native perforating of dipper rotary drilling.
The technical scheme that its technical problem that solves the utility model adopts is: dipper and hollow rotating shaft are connected as a single entity, hollow rotating shaft stretches in the shell and is dynamically connected with shell, fix by nut, be connected with gear wheel on the hollow rotating shaft, its gear wheel and pinion are meshing, a be dynamically connected end of hydraulic motor of pinion, the other end of hydraulic motor connects the woven hose that stretches out from main frame; Have the woven hose of hydraulic cylinder to stretch into wherein in hollow rotating shaft hollow and be connected with an end of woven hose rotating shaft, the other end of woven hose rotating shaft connects the woven hose that stretches out from main frame, and its woven hose rotating shaft is connected in the shell.When the starting hydraulic code reached, shell did not rotate, the dipper rotation, and simultaneously, the woven hose of hydraulic cylinder and then rotates together, owing to be provided with the woven hose rotating shaft, woven hose just can not twine mutually, can reach the purpose that rotates freely.
The beneficial effects of the utility model are: can be when excavating can multi-faceted excavation and loading, the native perforating of also recycling dipper rotary drilling.
