Described impact grinding mechanism, when running into hardness in the tunneling process and surpass the hardness that development machine allows, cutterhead shrinks; Quartering hammer stretches out, and face or large rock mass is carried out fragmentation, when being crushed to a certain degree; Quartering hammer is return the origin-location, and cutterhead stretches out, and face is cleared up.
Said installing rack comprises and driving main body rigidly connected holder and the supporting seat that is connected with holder, and the telescopic oil cylinder of described impact cutting mechanism is fixed on the supporting seat.
Conveying mechanism adopts the machine transport by company and airborne drag conveyor combines.
The company of said conveying mechanism adopts the machine transport and comprises shovel plate and thumb wheel, and the airborne relatively drag conveyor of thumb wheel is symmetrical set.
Development machine body rear side is equipped with the back and supports, and the back is supported and is provided with the horizontal side supporting mechanism, and said supporting mechanism is by HYDRAULIC CONTROL SYSTEM.
Beneficial effect of the present invention:
1. combined type cantilever development machine of the present invention; Increased impact grinding mechanism; Can the rock that cutterhead can not tunnel be smashed, both are used alternatingly, thereby have improved the driving ability and the operating efficiency of development machine greatly; Widen the range of application of cantilever development machine, thereby had vast market prospect.
2. combined type cantilever development machine of the present invention can be selected the impact grinding hammer of different size for use according to different geological condition and hardness, and can prolong the application life of pick greatly, reduces the cost of exchange, thereby can practice thrift substantial contribution for enterprise.
3. the dust pelletizing system of combined type cantilever development machine of the present invention has been improved staff's working environment greatly for can effectively reducing a large amount of dust that development machine work the time is produced, and has protected that the staff's is healthy.
4. combined type cantilever development machine of the present invention can not only be applied to the driving of various coal mine roadways, also can be applied to the driving of constructing tunnel, has greatly improved the scope of application of conventional cantilever development machine.
