Detailed ways:

The present invention will be further explained below in conjunction with the accompanying drawings.

As shown in Figures 1 to 5, the open-pit coal mining machine of the present invention includes a generator set 1, a mobile pump station 2, a main engine 3, a rear seat drill rod warehouse 4, a telescopic boom type auxiliary transport device 5 and a main drill rod library6.

Main frame 3 comprises two drill rod drive motors 31, each drill rod drive motor 31 all connects the input shaft of front transmission box 37 by a drill rod mechanism, is provided with drill bit 38 on the output shaft of front transmission box 37, and two An intermediate ventilation pipe 36 is provided between the drilling rod mechanisms. Drill rod mechanism is made up of drive reducer 32, middle long drill rod 33, double helix conveying drill rod 34 and stabilizer 35.

At the afterbody of the main engine 3, a backseat drilling rod storehouse 4, a rear palm bolt support 39 and an auxiliary rear support oil cylinder 40 are arranged. The back palm anchor support 39 is connected with the main engine 3 by the rear palm anchor support upper seat 47, the rear palm anchor support 39 is provided with a palm-shaped support oil cylinder 48 and the anchor mounting seat 42, and the bottom of the rear palm anchor support 39 is provided with A large number of neatly arranged conical protrusions 41 are supported by strong wear-resistant materials. The auxiliary back support cylinder 40 is connected with the back seat drill rod magazine 4 through the back support oil cylinder mount 43 . The rear drill rod storage 4 adopts a fixed steel structure box design, and the top is covered with rainproof materials to prevent the aging of the drill rod mechanism due to harsh environments. The rear drill rod storage 4 is also equipped with a rear anchor installation seat 44 .

When the drilling shearer works, the rear palm bolt support 39 is rotated to the desired position by the palm oil cylinder 48, and the conical protrusion 41 at the bottom of the rear palm bolt support 39 is inserted into the coal seam floor, and the conical protrusion 41 and the The frictional force between the coal seam floor forms the first stage to counteract the propulsion reaction force; install the anchor rod 45 on the anchor rod mounting seat 42 and the rear anchor rod mounting seat 44 respectively and lock it through the lock nut 46, and the bottom of the anchor rod 45 and the The bottom plate of the coal seam is fixed, and the supporting force of the anchor rod 45 to the main engine 3 and the back seat drill rod storehouse 4 is used to form a second level of counteracting propulsion reaction force; The back support oil cylinder 40 and the backseat drill pipe storehouse 4 can support the main engine 3, prevent the main engine 3 from moving, and then form the third stage to offset the propulsion reaction force.
