CRUSHER FOR EXPANSION BLADE FOR CRUSHING
To provide a crusher for cement mortar that can securely convert advance actuating force of a core rod into expanding actuating force of a right and a left expansion blade while improving strength of the right and left expansion blades so as to prevent deformation damage to the right and left expansion blade due to reaction force from a crushed body accompanying expanding actuation of the right and left expansion blades.SOLUTION: A crusher for expansion blade for crushing consists of a right and a left expansion blade and a core bar which is held between the right and left expansion blades, and expands the expansion blades. The core bar has an upper and a lower part formed into an upper and a lower half-tapered part, and an intermediate part formed into a flat part, and the upper half tapered part and lower half tapered part of the core bar are so formed that axial lengths thereof are longer than a forward/backward actuation range length of the core bar.SELECTED DRAWING: Figure 1
【課題】左右拡開刃の拡開作動に伴う被破砕物からの反力による左右拡開刃の変形損傷を可及的防止すべく左右拡開刃を強度向上させつつも芯棒の進出作動力を左右拡開刃の拡開作動力に確実に変換できるモルタル用破砕機を提供する。【解決手段】左右拡開刃と左右拡開刃の間に挟持されて同拡開刃を拡開させるための芯棒とより構成し、芯棒は、上部及び下部を上下半テーパー部とすると共に中間部をフラット部とし、芯棒の上半テーパー部と下半テーパー部のそれぞれの軸方向長さは芯棒の進退作動範囲長さよりも長くなるように形成してなることとした。【選択図】図１
