The object of the present invention is achieved like this: a kind of cutting part of heading machine, comprises cutterhead, stretching device, telescopic oil cylinder, cut reductor, cutting motor and cutting units backplate, it is characterized in that:
A) cutting part of heading machine also has a power box, telescopic oil cylinder, cut reductor and cutting motor are installed in power box, the front and back end of power box is adpting flange, stretching device is connected by front end adpting flange with the housing of cut reductor, the input of cut reductor is connected by shaft coupling with the output of cutting motor, the housing of cutting motor is connected with power box rear end adpting flange, the housing of telescopic oil cylinder is fixedly mounted on the inwall of power box both sides, and cutting units backplate is arranged on the outer wall of power box;
B) the cylinder bar of telescopic oil cylinder stretches out power box and is connected with stretching device, and cutterhead is positioned at the front end of stretching device.
In the present invention: described power box roof is provided with the oil filler point installing preformed hole and cut reductor.
In the present invention: described cutting units backplate is arranged on the outer wall at power box top, the protective range of cutting units backplate comprise install preformed hole, cut reductor oil filler point and be in the telescopic oil cylinder cylinder bar of maximum overhang.
In the present invention: described installation preformed hole comprises cut reductor and cutting motor puts into hole, shaft coupling installs adjustment hole and telescopic oil cylinder installing hole.
The invention has the advantages that: because cut reductor and cutting motor are installed in power box, the moment produced when bearing cut by power box, effectively improve the stressing conditions of cut reducer shell, improve the whole service life of cutting units device; Because telescopic oil cylinder is arranged on the both sides of power box inside, when telescopic oil cylinder cylinder bar stretches out maximum, cylinder bar exposed parts, in the protection of cutting units backplate, effectively plays anti-protective effect of pounding to telescopic oil cylinder; Because power box roof is provided with the oil filler point installing preformed hole and cut reductor, make telescopic oil cylinder, cut reductor and cutting motor convenient in power box installation and maintenance.
