Dual-purpose device for drilling and cleaning well

Abstract

The invention discloses a dual-purpose device for drilling and cleaning a well. The device comprises a guide drill bit, shovel teeth, a lifting device, a hydraulic motor, a hydraulic automatic control oil cylinder assembly and a pressure-bearing fixing rack, wherein the hydraulic motor is mounted at the lower end of the pressure-bearing fixing rack; a lower end output shaft of the hydraulic motor is provided with a cross-shaped shovel tooth rack; the guide drill bit is mounted at the central position of the shovel tooth rack; the shovel teeth are mounted on left and right plates of the shovel tooth rack; flat shovel blades are mounted on front and rear plates of the shovel tooth rack; and the lifting device is mounted between the shovel tooth rack and the hydraulic motor. The dual-purpose device for drilling and cleaning the well disclosed by the invention has the advantages of convenience in operation, easiness of detaching and mounting, safety and reliability in utilization, small volume, light weight, convenience for transferring and improvement of working efficiency; the dual-purpose device has functions of drilling and cleaning the well, is low in noises and high in hydraulic working pressure and does not cause environmental pollution; the dual-purpose device is convenient to maintain and mount and is low in manufacturing cost; and the requirements on construction conditions are not high and the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to an engineering machinery drilling device, in particular to a dual-purpose device for drilling and cleaning with the functions of drilling and cleaning. Background technique [0002] At present, domestic and foreign engineering construction, mining, agricultural irrigation, accident rescue, etc. all need drilling and cleaning equipment. The previous drilling machines and cleaning machines are not standardized, and there are many shortcomings, such as environmental pollution caused by high noise in the piling process; mechanical fuel consumption A large amount of cost is high and causes environmental pollution; a project often requires more construction personnel; the volume of equipment is too large, not only inconvenient for transfer and transportation, but also causes increased construction costs; low construction efficiency; The bottom of the well is uniform or the depth of the well is different, which brings troubles to the ...
