cutting head of longitudinal axial roadheader. Introduction . As a mechanical versatile excavation equipment, longitudinal axial roadheader has a wide range of applications for mine production, tunnelling and other industry. The design capacity of the roadheader indicates the level of the development of industry in a country.
A roadheader, also called a boom-type roadheader, road header machine, road header or just header machine, is a piece of excavating equipment consisting of a boom-mounted cutting head, a loading device usually involving a conveyor, and a crawler travelling track to move the entire machine forward into the rock face.
Develop the longitudinal cutting head of roadheader parametric modeling interface based on Visual C++ language, to achieve front interface input, and the front desk to call ANSYS system. Achieve the relevant calculation parameters of the cutting head of roadheader input directly in the interface of the system, and anti-call input the
The mechanism of cutting process of roadheader with cutting head was researched, and the influences of properties of coal and rock on cutting load were deeply analyzed. Aimed at the defects of traditional calculation method of cutting load on fully expressing the complex cutting process of cutting head, the method of finite element simulation was proposed to simulate the dynamic cutting process.
cutting head shapes (spherical, conical, cylindrical) and combined heads are commonly used. Since the boom forces vary as a function of the cutting head geometry, the stability of a roadheader is also affected,. In this study, the effects of cutting head shape on stability were quantitatively investigated for a longitudinal cutting head roadheader.
Cutting Head. Cutting head is optimized with emulation technique; cutting tooth layout is reasonable and rock breaking capacity is strong. Spraying System. Spraying system of EBZ75 type road header consists of internal spraying system and external spraying system. Internal spraying system is to …
Its output torque is large and it is suitable for operation with large dip angle. If there is limit on weight or overall height during transportation, the roadheader can be dis-assembled to transport. Features and accessories . cutting boom; low height design transversal cutting head / longitudinal cutting head
Jan 01, 2007 · A longitudinal cutting head type roadheader has been analyzed along its maximum cutting profile by using the developed method. A spherical cutting head having 69° tilt angle of corner pick was used in the machine.
