Problems solved by technology

[0004] In the prior art, the fragmentation of steel bars is usually done manually by using a hand-held grinder to cut off the steel bars one by one. On the one hand, the efficiency is extremely low. On the other hand, the length of the steel bars after cutting is long, which is not conducive to the subsequent treatment of waste. Utilization of steel bars

Abstract

The invention relates to the technical field of material crushing and discloses a steel bar crushing method and steel bar crushing equipment adopting the crushing method. The steel bar crushing equipment comprises a pair of rotating cutter shafts and a main shearing cutter seat, wherein the pair of the rotating cutter shafts are correspondingly arranged on two sides of the main shearing cutter seat. Cutter heads are arranged on the rotating cutter shafts, shearing cutter teeth are arranged on the cutter heads, a shearing groove penetrating up and down is formed in the main shearing cutter seat, and the two sides of the tooth width and the tooth top of each shearing cutter tooth are correspondingly matched with the two sides and the groove bottom of the shearing groove. A steel bar is thrown downward from the upper part of the main shearing cutter seat, so that the steel bar falls between the pair of rotating cutter shafts. The rotating cutter shafts rotate, the shearing cutter teeth onthe rotating cutter shafts hook the steel bar, and the steel bar is pressed down to the upper plane of the main shearing cutter seat. The rotating cutter shafts continue to rotate to press and shearthe steel bar located at the groove in the main shearing cutter seat. The steel bar crushing method and the steel bar crushing equipment realize the automation of steel bar crushing and further improve the efficiency and quality of steel bar crushing.

Description

technical field [0001] The invention relates to the technical field of material crushing, in particular to a steel bar crushing method and steel bar crushing equipment adopting the crushing method. Background technique [0002] Rebar is a type of steel used in reinforced concrete buildings or building elements, usually circular in cross-section, sometimes square with rounded corners, including plain round bars, ribbed bars, twisted bars, etc. [0003] During the demolition process of urban buildings, a large number of scrap steel bars will be produced. These scrap steel bars have different shapes and are often entangled. In order to realize the recycling of the scrap steel bars, the scrap steel bars need to be shredded during the processing of the scrap steel bars, that is, the steel bars are cut into small sections or granular shapes for subsequent further processing. [0004] In the prior art, the fragmentation of steel bars is usually done manually by using a hand-held g...
