Rotary excavating drill bit with noise reduction function and construction method thereof
The invention discloses a rotary drilling bit with a noise reduction function and a construction method of the rotary drilling bit. The rotary drilling bit comprises a switching assembly and a pair of barrel petals, and the barrel petals are hinged to the peripheral side of the switching assembly; the adapter assembly comprises a square adapter, a connecting shaft and a disc seat, and the cylinder petals are connected to the peripheral side of the disc seat through hinge shafts; a flow channel is formed in the cylinder section, and a flow channel port is formed in the upper part of the flow channel; a transverse pipeline is arranged in the disc seat, a pipeline port is arranged at the end part of the transverse pipeline, and the transverse pipeline is communicated with an external heat flow source; and one end of the flexible pipe is connected to the flow channel port, and the other end of the flexible pipe is connected to the pipeline port, so that an external heat flow source can flow to the flow channel in the barrel section through the transverse pipeline and the flexible pipe, the temperature of the inner side wall of the barrel section is increased, and the friction coefficient of a soil body in the rotary excavating drill bit and the inner side wall of the barrel section is changed.
本发明公开了一种具有降噪功能的旋挖钻头及其施工方法，所述旋转钻头包括转接组件和筒瓣，所述筒瓣的数量为一对并铰接于所述转接组件的外周侧；所述转接组件包括方形的转接头、连接轴和盘座，所述筒瓣通过铰接轴连接于所述盘座的外周侧；所述筒瓣的内部设置有流道，所述流道的上部设置有流道端口；所述盘座的内部设置有横向管路,所述横向管路的端部配置有管路端口，所述横向管路与外部的热流源连通；还包括柔性管，所述柔性管的一端连接于流道端口，其另一端连接于所述管路端口，使得外部的热流源能够经由横向管路及柔性管流向筒瓣内部的流道，使得筒瓣内侧壁的温度升高，以改变旋挖钻头内部土体与筒瓣内侧壁的摩擦系数。
