Abstract

The invention relates to a pollutant discharging and dredging device for an excavator, comprising a connecting frame, a hydraulic motor, a hydraulic motor mounting seat, a mud pump, a pollutant discharging pipe, a coupling, and an oil inlet and oil return pipe and a hydraulic quick coupler thereof, wherein the hydraulic motor mounting seat is fixed on the shell of the mud pump; the hydraulic motor is fixed on the hydraulic motor mounting seat; the power output shaft of the hydraulic motor is connected with the power input shaft of the mud pump through the coupling; one end of the connecting frame is provided with a cage type frame body and is fixed on the shell of the mud pump; the hydraulic motor and the hydraulic motor mounting seat are arranged in the cage type frame body; the other end of the connecting frame is provided with a connecting shaft to be connected with the dipper handle and connecting rod of the excavator or a quick change device; the oil inlet and oil return port of the hydraulic motor is connected with one end of the oil inlet and oil return pipe, and the other end of the oil inlet and oil return pipe is connected with the hydraulic quick coupler; and the pollutant discharging pipe is connected with the outlet of the mud pump. The device is assembled on the excavator for use and is convenient and flexible to dredge medium and small areas.

Description

technical field [0001] The invention relates to a multifunctional accessory tool of an excavator, in particular to a sewage discharge and dredging device for an excavator. Background technique [0002] The excavator is a very important machine in the construction machinery industry. Its function has long since broken through the function of only digging various soils. After the excavator bucket is removed, it can be directly or indirectly (through a mechanical quick change device or hydraulic pressure) Quick change device) to install various excavator accessories, such as fork device, hydraulic breaker, auger drill, vibratory plate compactor, hydraulic vibratory hammer, etc., to realize the multi-functional operation of the excavator to meet the different construction operations of customers demand, maximize the utilization rate and added value of the excavator, and create the greatest value. Since the excavator can be driven by crawler or tire, and has good off-road perform...
