This paper studies the design of the hinge position of the boring machine part of the roadheader. According to the problems existing in the design of the hinge position of the shovel part, the motion characteristics of the shovel part are analyzed, the structure of the shovel part is simplified, and the movement diagram of the mechanism is drawn. According to the type of hinge mechanism of the shovel part, the relationship between the movements of the mechanism is discussed, and the positional relationship between the position points of the shovel part is given, and the solution equations are established. In order to verify the correctness of the equations, different examples are selected, and the MATLAB programming is used to solve the position equations of the hinge part of the shovel. The results show that the method is correct and feasible, and provides a reliable design for the rapid design and calculation of the position of the shovel part of the boring machine. The factual basis reduces the design difficulty and improves the design efficiency of the blade part.
