Abstract

The present invention provides a blast electric hammer for powerful hole cleaning after hole drilling for embedding steel bars. The blast electric hammer comprises an electric hammer body, a blast blade group and a blade protecting cover, wherein the blast blade group comprises a hub and first blades; the hub is arranged in the center of the blast blade group; first blades are fixedly arranged on the hub; a clamp at one end of the electric hammer body is connected with the hub through a rotating shaft; the blade protecting cover covers the blast blade group; and an air outlet pipe is arranged at one end of the blade protecting cover. The blast electric hammer provided by the invention has the beneficial effects that the blast blade group is fixed to the clamp of the electric hammer through the rotating shaft; powerful outlet air of the air outlet pipe can be used for carrying out blast cleaning on drilled holes; and the blast electric hammer has dual functions of hole drilling for embedding the steel bars and blast hole cleaning, other equipment is not needed and the blast electric hammer is very convenient to use.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a blower electric hammer which is used for self-powerful hole cleaning after drilling with reinforcement. Background technique [0002] The electric hammer is the main equipment for drilling in the process of planting bars in construction. The structure of the electric hammer is composed of a motor, a gear reducer, a crank connecting rod impact mechanism, a brazing mechanism, an overload protection device, a power switch and a power connection device. Among them, the drill turning mechanism is driven by a motor through gears to a pair of straight bevel gears, so that the cylinder liner rotates together with the hexagonal liner through the load protection device, and transmits the torque to the drill pipe. In this way, the compound movement of the impact belt rotation is formed simultaneously with the impact mechanism. Mainly impact, supplemented by rotation, hamm...
