    • PROBLEM TO BE SOLVED: To provide a boring machine used to bury a boring pipe in the ground.SOLUTION: There is provided a boring machine which has a motor-integrated reduction gear in its forefront body and a direction correcting device and bypass valve in its body. The motor-integrated reduction gear has a hollow pipe passing through the inside thereof so that chemical or lubricant can be injected directly to bits. The direction correcting device is installed between the forefront body and the body to support the forefront body, and an inner surface of a joint mounted on the body receives a sphere formed at the tip of a cylinder rod mounted on the forefront body so that the forefront body is supported so as to freely swing. The bypass valve controls opening/closing of the bypass of a mud feeding pipe and a mud discharge pipe by driving a revolving-door-shaped rotary valve. The rear end of the boring machine is joined with a joint member having a center pipe, a mud feeding pipe, a mud discharge pipe, and a fluid pipe.
    • 要解决的问题:提供一种用于将钻孔埋入地下的镗孔机。 解决方案:提供一种镗床,其前端具有电动一体化的减速齿轮,其身体上具有方向校正装置和旁通阀。 电机一体化的减速齿轮具有穿过其内部的中空管,使得可以将化学品或润滑剂直接注入钻头。 方向校正装置安装在前沿体和身体之间以支撑前沿体,并且安装在主体上的接头的内表面接收形成在安装在前沿体上的气缸杆的尖端处的球体,使得前端 身体被支撑以便自由摆动。 旁通阀通过驱动旋转门形的旋转阀来控制泥浆输送管和排泥管的旁路的打开/关闭。 镗床的后端与具有中心管,泥浆输送管,泥浆排出管和流体管的接头构件连接。 版权所有(C)2012,JPO&INPIT
