With running clearance；Pressure at the delivery outlet 101b of emulsion delivery pump is transferred to hydraulic drive by pressure transmitter device 104
Moving part 134 provides driving force for hydraulic-driven part 134；When driving force is more than or equal to preset pressure value, bindiny mechanism 133 exists
Connection driving shaft 131 and driven shaft 132 and both drive rotates synchronously under the driving of hydraulic-driven part 134, emulsion conveying
The input shaft of pump 101 and the drive shaft of fluid pressure drive device 102 are in connecting shaft state, when driving force is less than preset pressure value,
In the connection disconnected under the driving of hydraulic-driven part 134 and between driving shaft 131 and driven shaft 132, emulsification is fried for bindiny mechanism 133
The input shaft of medicine delivery pump 101 and the drive shaft of fluid pressure drive device 102 are in non-connecting shaft state.
Wherein, emulsion delivery pump 101 is primarily used for the device of pumping explosive, can be applied to any explosive loading system
In system, material is sucked by the input port 101a of emulsion delivery pump, then passes through the delivery outlet of emulsion delivery pump
101b transfers out material, and emulsion delivery pump 101 provides power, fluid pressure drive device by fluid pressure drive device 102
102 can be used the device skilled person will appreciate that being hydraulically operated, such as hydraulic motor, using fluid pressure drive device 102
It can avoid using control panel, to avoid the generation of accident under coal mine.
Arrangement of clutch 103 is connected between emulsion delivery pump 101 and fluid pressure drive device 102, realizes clutch for clutch control.
Specifically, Fig. 2 gives the left view structural representation of 103 1 embodiment of arrangement of clutch of the present invention, as shown in Fig. 2, arrangement of clutch
103 include: driving shaft 131, driven shaft 132, bindiny mechanism 133 and hydraulic-driven part 134；Driven shaft 132 and driven shaft 132 are logical
Often it is cylindrical shape structure, can be rotated around respective central axes, driven shaft 132 has axial cavity, it covers outside driving shaft 131,
Driving shaft 131 is placed in the axial cavity and has running clearance namely driving shaft 131 between the inner sidewall of driven shaft 132
