Abstract

The invention relates to the coal mine, mine and engineering tunnel digging fields, and concretely relates to a cutting mechanism of a heading machine which solves the problems of poor sealing effects due to large radial seal work area and diameter existed in an inner spray system of the current heading machine. The cutting mechanism comprises a cutting head, a cutting decelerator, a telescoping part, a cutting motor and a heading machine body; the cutting head is directly connected with the cutting decelerator, the cutting head is connected with a second grade ring gear of the cutting decelerator, the cutting motor is arranged in the telescoping part and slideablely matched with the telescoping part. Wherein, the cutting decelerator is different with the current cutting decelerator of the heading machine, the cutting decelerator uses the ring gear for output. The structure realizes that the sealing of the water channel which serves water required by inner spray before flowing out of the decelerator is static sealing, and the diameter for dynamic seal is reduced while water is flowed out of the cutting decelerator, so that the reliability of inner spray sealing is substantially raised. The cutting mechanism can be widely used for various current heading machines.
