No matter be any Placement, all can bring very large inconvenience to labourer, all reduced working efficiency, and cost is high.

At present the commutation Placement of pneumatic drilling machine all can increase the connection of pipeline, increases joint quantity, increases the weight of complete machine, and mobile drill is very inconvenience all, and various terminal is obscured easily, has reduced workman's efficiency, and cost is high.

The model utility content

The utility model technical issues that need to address provide the pneumatic rotary rig operation control module that a kind of connecting pipeline is few, quality is light, cost is low.

For addressing the above problem, technical solution adopted in the utility model is: a kind of pneumatic rotary rig operation control module, comprise valve body, spool, sealing gasket, valve gap, spanner, fittings body, wherein spool is installed in the hole of valve body, by the sealing gasket sealing, spanner is connected with spool top between valve body and the valve gap.

There is the groove of two symmetries at described spool cylindrical body middle part, and there is respectively individual O RunddichtringO groove at two ends, and the upper-end surface arranges location aperture, restraining groove.Described spool is two, a big valve core, corresponding large spanner, control swirl gear, a small valve core, corresponding small wrench, control feed mechanism.

Described valve body is that cast inblock forms, valve body is provided with revolution suction port, feeding suction port, revolution relief opening and feeding relief opening, an air-inlet cavity and an exhaust cavity, wherein turn round suction port and feeding suction port and communicate with air-inlet cavity simultaneously, revolution relief opening and feeding relief opening communicate with exhaust cavity simultaneously.

Described valve gap with location aperture and spacing hole, is fixed on above the valve body.

The beneficial effect that adopts technique scheme to produce is: the utility model is integrated in the pneumatic control valve of swirl gear and feed mechanism on the operational module, reduced the complex pipeline of the revolution connection of being connected with feed mechanism, reduced conduits of energy consumption, the smooth running reliable in quality, also deducted simultaneously operating table, make the boring working surface cleaner and tidier, alleviated complete machine weight, reduced the labor intensity of underground labour's telephone-moving, reduced the combination miss that the workman operates rig, improve workman's efficiency, and reduced cost.
