Abstract

The invention aims to provide a mechanical arm of an earth auger. The mechanical arm comprises a lifting device and a variable-diameter drill bit device arranged on the lifting device, and is characterized in that the variable-diameter drill bit device comprises a disc, at least one variable-diameter drill bit is fixedly arranged at the bottom of the disc, and each variable-diameter drill bit comprises an inverted U-shaped fixing plate, a second lead screw in transmission connection with the inverted U-shaped fixing plate, a fixing mounting base in transmission connection with the second leadscrew, a expanding push rod fixedly arranged at the bottom of the fixing mounting base and a auger bit body fixedly connected to the expanding push rod. According to the mechanical arm, the problems that an existing earth auger for digging a pit for a power grid pole cannot change the diameter, drill bits with different diameters are required to be arranged for different pit diameters, and the pitdigging efficiency is low can be solved.

Description

technical field [0001] The invention belongs to the technical field of digging machines, in particular to a mechanical arm of a digging machine, and belongs to the field of electric machinery. Background technique [0002] At present, when the poles of power supply lines are operated on the poles, they are generally constructed manually or with the cooperation of cranes and manual labor. The labor intensity is high and the cost of digging holes is high. Then digging machines appeared to solve the above problems. [0003] However, the mechanical arms of the digging machines for power grid towers in the prior art all use helical blades. The defects of the mechanical arms of this digging machine are: the diameter cannot be changed, different pit diameters must be equipped with drill bits of different diameters, and the excavation rate Low. Contents of the invention [0004] The object of the present invention is to provide a variable-diameter drill bit to solve the problems ...
