Spiral drilling machine

Abstract

The invention discloses a spiral drilling machine which comprises an oil seal cover. A bearing seat, a secondary rotation assembly, a flange and a motor outer shell are sequentially connected above the oil seal cover. An output shaft is connected to the inner sides of the oil seal cover and the bearing seat. One end of the output shaft penetrates through the bearing seat and the oil seal cover and is used for being externally connected with a load. The other end of the output shaft is engaged with the secondary rotation assembly. A secondary sun lgear in the secondary rotation assembly penetrates through the flange and is connected with a primary rotation assembly in an engaged mode. A primary sun gear shaft in the primary rotation assembly is connected with a hydraulic motor installed on a motor base in an engaged mode. The primary rotation assembly, the motor base and the hydraulic motor are all connected inside the motor outer shell. The spiral drilling machine has the beneficial effects that the spiral drilling machine can be used for mounting various drill bits, and through the primary rotation assembly and the secondary rotation assembly, large torque output can be achieved when a small-displacement hydraulic motor is adopted; and in addition, the primary rotation assembly and the secondary rotation assembly are connected in an engaged mode, a split structure is adopted, the structure is reliable, and maintenance is convenient.

Description

technical field [0001] The invention relates to an auger drilling device, which is used to drive a drill bit for construction in various operations such as piling. Background technique [0002] At present, in the construction of general construction projects, it is often necessary to drill holes in some drilling equipment. Usually, an auger drill is used to provide kinetic energy to the drill bit for construction. The traditional auger drill is usually powered by a motor, and the power is transmitted to the drive shaft by means of transmission gears. Drive the drill bit to operate. Although the above structure can meet the basic work needs, for some relatively hard geology, a large motor is needed to generate enough power. The large displacement motor is large in size and heavy in weight, which is inconvenient for installation and maintenance. How to increase power without sacrificing volume and quality is an important technical problem that those skilled in the art need to ...
