Parametric Design of Spiral Drill Pipe for Drill Type Shearer

Drill type coal mining machine is the mining equipment used for a thin and very thin seam.Spiral drill pipe is the important part of the drilling shearer to realize the function of power transmission and transportation of coal. The design strength and service performance are the main factors that affecting the performance of the drill type coal mining machine. In order to achieve the parametric design of the spiral drill pipe, the main parameters and design formula of the spiral drill pipe are derived based on the kinematics and mechanics analysis of the coal particle. And combined with the method of parametric design, write the main parameter calculation formula program by using the software of Drive Works Solo. The establishment of user interface to realize the automatic assembly,interference check and clearance verification of spiral drill pipe. Finally, different parameters series of spiral drill pipe 3D models are built. The design cycle of the spiral drill pipe is shortened by using the method of parametric design, and the design efficiency is improved. It is conducive to realize the product series of the spiral drill pipe.
