A breaking hammer with an annular cutting blade

Abstract

The invention belongs to the technical field of breaking hammers and particularly relates to a breaking hammer with an annular cutting disc. The breaking hammer comprises guide rails, a rotary driving mechanism, cushion blocks, the annular cutting disc, sawteeth, hydraulic rods and a drill rod, wherein the drill rod is arranged inside a drill rod sleeve through sliding fit of drill rod guiding blocks and drill rod sleeve sliding holes; a drill rod spring is arranged on each guiding block; when the drill rod beats in a reciprocating way for working, a function of resetting the drill rod is realized; the rotary driving mechanism can vertically move on the guide rails on the drill rod sleeve through the cushion blocks; under the supporting of a hydraulic supporting ring, three hydraulic rods which are uniformly arranged in the circumferential direction control vertical moving amplitude of the rotary driving mechanism through the stretching of the hydraulic rods; and a thin-wall support, an annular plate support and the annular cutting disc are mutually fixed together and can vertical move along with the rotary driving mechanism. According to the breaking hammer disclosed by the invention, circular sawteeth can be driven by rotation of the rotary driving mechanism to rotate for cutting reinforcing steel bars, cutting action is simple and reliable, and a certain practical effect is realized.

Description

Technical field [0001] The invention belongs to the technical field of breaking hammers, in particular to a breaking hammer with an annular cutting piece. 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,...
