Crushing tooth for crusher

Abstract

The invention aims at providing a breaking tooth for a disintegrator that the replacing work of the swing type ram hammer is realized without unloading the swing axle supporting the swing type ram hammer and the intensity of the hammer is not reduced under the centrifugal force produced by the rotation of a rotor. As a notch (30) with an opening part (31) is formed at the hammer (11), a hammer rocking pin (24) can be inserted from the opening part (31), thereby inserting the hammer rocking pin (24) into a pinhole (29) of the hammer (11). A breaking tooth fastener (35) is taken out for the inserting part (37) and a dovetail part (38) tabled with the opening part (31) of the hammer (11) and a dovetail groove (32) from the direction of the arrow. The bolt is inserted from the periphery of a circular plate (23) and the outside and a screwed hole (41) of the breaking tooth fastener (35) is pinched, thereby fixing the hammer (11) and the breaking tooth fastener (35) mutually.

Description

technical field [0001] The present invention relates to pulverizer teeth for recycling asphalt slag, concrete waste, and the like. In more detail, it relates to an attachment structure of crushing teeth for a crushing machine mounted on the tip of an arm of a civil engineering machine and used for an impact crusher mounted in a bucket with a crushing cover having a function of crushing raw materials . Background technique [0002] In general, the so-called impact crusher is used for crushing and crushing crushed materials such as industrial waste, concrete waste or asphalt mixed blocks, civil engineering aggregates, or crushed stones, and the crushed materials are recycled and reused. Material reuse. The structure of this impact mill is that in the case, several hammers are arranged along the radial direction, and the rotor with a horizontal axis is rotated. Through the rotor, the thrown material to be pulverized is arranged on the inner surface of the case and fixed to th...

Problems solved by technology

[0011] Impact hammers need to be replaced frequently due to wear and other reasons, and in order to achieve miniaturization, the space for replacement work is difficult to carry out, so these work must be performed as efficiently as possible

Especially in the case of an oscillating impact hammer, it is necessary to remove the oscillating shaft for replacement, and even other hammers installed on the oscillating shaft that do not need to be replaced must be disassembled once.
