Low-vibration type electric pick

Abstract

The invention relates to a low-vibration type electric pick. The low-vibration type electric pick comprises a shell, a motor, a switch button, a cover body, a sliding block, a striking pin, a crank, aswing rod, two transmission rods, two striking hammers and two compressed springs. The front ends of the transmission rods are installed in sliding grooves in the striking hammers in a sliding mode,so that the transmission rods and the striking hammers are in non-rigid connection, after the transmission rods impact the striking hammers, kinetic energy of the transmission rods is transmitted to the striking hammers, the striking hammers independently accelerate and impact the sliding block forwards under the inertia effect of impact force, the sliding block moves forwards to drive the striking pin to break a wall, strong counter-impact force generated by strong vibration force generated when the impact hammers impact the sliding block on the arm of an operator is avoided, meanwhile, the swing rod is driven by the crank to swing front and back, the two transmission rods impact the two impact hammers alternately, the impact frequency is improved, the working efficiency is higher, and meanwhile noise is reduced.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a low-vibration electric pick. Background technique [0002] Electric pick is a hand-held electric tool, which is widely used in pipeline laying, mechanical installation, water supply and drainage facilities construction, interior decoration, port facilities construction and other construction projects. For example, the Chinese invention patent No. 2018109814431 discloses a Switched reluctance electric pick, which includes a shell, a first handle, a motor box, a second handle, a baffle, a slag discharge pipe, a fixed head, a dust suction pipe, a drill bit, a delivery pipe, a cooling hole, a box body, an exhaust pipe, Dirt storage box, filter screen, fan, protruding head, card slot and cover plate; by connecting the cover plate on one side of the electric pick housing, the cover plate can block the heat dissipation holes during work, and external objects are not easy to ent...

AI Technical Summary

Problems solved by technology

[0003] Through the research on the above-mentioned electric picks and the existing electric picks, it is found that they are all rigidly connected with the transmission rod and the percussion hammer as a whole, so that the strong impact and vibration force generated by the percussion hammer on the drill bit will have a relatively strong impact on the operator's arm during work. Strong anti-impact force, which is not conducive to the operator's operation, and the strike frequency of the existing electric pick is low, and the motor can only strike once per revolution, resulting in low work efficiency;
