- Abstract
On the base of the theoretical analysis of the rotary cutting of a single picker, a series of experiments were carried out on the cutting test bed of coal and rock to explore different forms of pick-type cutting coal seam. As such the time domain analysis was carried out on the signal of the cutting pick under different compressive strengths, the cutting thickness, the cutting cone angle, the drum speed, and the impact angle. Through the experiment, some conclusions could be capable to conclude that the cutting load changes differently under diversified circumstances. The cutting load will increase because of the growth of the compressive strength, the reduction of the drum speed, the growth of the cutting thickness, and the reduction of the cutting angle. In the process of increasing the impact angle, the cutting load will first increase and then decrease, and the corresponding impact angle is about 48° when it reaches the minimum value.
