Description

复合采掘机截齿
技术领域:
本实用新型属于破煤岩工具,主要用于煤矿采掘机,具体涉及一种复合采掘机截齿。
背景技术:
在实际应用中,现有截齿的合金头容易崩掉,齿体硬度增大,韧性减小,容易断裂,从而使截齿的使用寿命较短。造成万吨消耗量较大,增加了产煤成本。
发明内容:
本实用新型旨在提供一种韧性较好、使用寿命较长的复合采掘机截齿。
实现本实用新型的技术方案是:包括齿套、齿体,齿体由齿头、齿柄构成,其特征是齿头与齿柄锻造为一体,齿套套在齿柄的外围,齿头端部设有锥形合金头,锥形合金头与齿头镶嵌为一体,齿柄上设有一个环形凹槽,环形凹槽上设有筒簧。
本实用新型韧性较好、使用寿命较长,可以降低万吨消耗量,降低产煤成本。
附图说明:
图1是本实用新型实施例中齿头和齿柄锻造为一体的结构图。
图2是本实用新型实施例中齿套的结构图。
图中:1.锥形合金头;2.齿头;3.齿柄;4.筒簧;5.齿套。
具体实施方式:
实施例:图1、图2所示,本实施例包括齿套5、齿头2、齿柄3,其特征是齿套5套在齿柄3的外围,齿头2与齿柄3锻造为一体,齿头2的端部设有锥形合金头1,锥形合金头1与齿头2镶嵌为一体,齿柄3上设有一个环形凹槽,环形凹槽上设有筒簧4,筒簧4可以相对齿柄3旋转。
