Breaking hammer with double cutting blades

Abstract

The invention belongs to the technical field of breaking hammers, and particularly relates to a breaking hammer with double cutting blades. The breaking hammer comprises guide rails, a rotating driving mechanism, cushion blocks, cutting wheels, hydraulic rods and a drill rod, wherein the drill rod is mounted inside a drill rod sleeve through the sliding cooperation of drill rod guide blocks and drill rod sleeve sliding holes; drill rod springs are mounted on the guide blocks; when the drill rod performs reciprocating knocking, the drill rod springs exert a drill rod resetting function; the rotating driving mechanism can move up and down on the guide rails on the drill rod sleeve through the cushion blocks; the three hydraulic rods which are uniformly mounted in the circumferential direction control the up-and-down motion amplitude of the rotating driving mechanism through the self extension and retraction under the support of a hydraulic support ring; and a thin-wall support, an annular plate support and a double-cutting blade mechanism are fixed together, and can move up and down along with the rotating driving mechanism. According to the breaking hammer, the rotating driving mechanism can drive the double-cutting blade mechanism to rotate and locate, a cutting motor drives the double cutting blades to cut rebar, the cutting action is simple and reliable, and the breaking hammer has certain practical effect.

Description

Technical field [0001] The invention belongs to the technical field of breaking hammers, in particular to a breaking hammer with double cutting blades. Background technique [0002] At present, the breaking hammer often only has the crushing function. When the object to be crushed contains steel bars, it needs to be cut with a chainsaw, which will affect the crushing efficiency. Of course, some companies install scissors on the breaker to shorten the steel bar when researching the breaker, or cut it by installing an electric saw, but the installation positions of these two methods on the breaker are fixed. When the direction of the steel bar When it does not match the cutting direction of the scissors or the direction of the chainsaw, it is necessary to control the direction of the vehicle to control the position of the hammer, which will also affect the efficiency of the entire crushing. [0003] In order to improve the efficiency of the breaker when cutting steel bars, th...
