Abstract

The invention discloses an electric pick which comprises a machine shell, a motor, a transmission system, an impact system and a chuck, wherein the motor, the transmission system and the impact systemare arranged in the machine shell, at least part of the chuck extends out of the machine shell, and the chuck is provided with a containing hole with a hexagonal outline; the impact system comprisesan air cylinder, a connecting rod at least partially arranged in the air cylinder, a piston, an air cushion, a ram and a ram rod; the transmission system is arranged on the side, close to the chuck, of the motor and used for transmitting power output by the motor to a connecting rod of the impact system, the connecting rod drives the piston to do reciprocating motion, the piston compresses the aircushion in a reciprocating mode, and the air cushion sequentially transmits energy of the piston to the ram and the ram rod, so that a working head is driven to do reciprocating motion; and the innerdiameter of the air cylinder is 30-35 mm, the maximum output power of the motor is larger than 1000 W, and the overall weight of the electric pick is smaller than or equal to 5.2 kg. The electric pick is optimized and improved, and is easier and more convenient to operate on the premise that the working efficiency of the electric pick is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to an electric pick. Background technique [0002] Electric pick is a hand-held electric tool widely used in pipeline laying, mechanical installation, water supply and drainage facilities construction, interior decoration, port facility construction and other construction projects. It can be used to crush concrete, masonry structures and asphalt pavement , Chiseling, excavation, slotting, cutting and other operations. [0003] Generally, the electric pick includes: a casing, a cylinder located in the casing, an impact system, a motor and a transmission system, etc. At present, during the use of electric picks, there are generally problems of heavy weight, inconvenient operation, and low work efficiency. Especially for electric picks with a cylinder diameter of 30-35 mm, the weight of the whole machine is generally between 5.5 kg and 6 kg without including the power cord and...
