Dynamic, when described travel limit nut touches the upper lid of described powder inner core processed, due to the supporting function of upper lid, thus limiting institute
State cylinder to continue to move downward, so can control powder inner core bottom processed opens scope, thus control discharging speed and
Rationally utilize the space in outer tube.It is further preferred that being provided with external screw thread on described cylinder rod 58, described formation limits nut
On be provided with female thread so that described formed limit nut can on described cylinder rod 58 its position of up-down adjustment, this
Sample can need to arrange the aperture of described inner core bottom according to different.The lower end of described cylinder rod 58 is also by the mode of screw thread
It is connected with powder inner core bottom opener processed.Described powder inner core bottom processed is suspended in powder processed by powder inner core bottom opener processed
Cylinder bottom.
Described feed chute is arranged on powder inner core center upper portion position processed, and described air pipe joint is arranged on feed chute
On, described purge air import is actual to be air pipe joint and feed chute joint, and communicates with inside feed chute, described
Sloping platform is arranged on the bottom inside powder outer tube processed, and described discharging elephant trunk is arranged on outside powder outer tube processed, and is in tilt with sloping platform
That consistent side of face discharging direction, described discharging opening actual for powder outer tube processed and discharging elephant trunk joint, and with powder processed outside
Cylinder communicates.
When being passed through power supply and starting working, external rotor electric machine outer rotor is first begin to rotate external rotor electric machine, turns around outer
Sub-motor axle 12 heart produces a larger rotation torque, so that described flour mill moment rotates, meanwhile turns with outer
Sub-motor shell is indirectly connected with after described eccentric hammer obtains a larger rotation exciting force when rotating described flour mill moment
Rotate rapidly and quickly reach the poised state of circumferential movement.Due to described eccentric hammer axle with external rotor electric machine output shaft only
It is to be indirectly connected with by elastic shaft coupling pad 42, do not constitute power transmission mechanism, and eccentric hammer axle upper and lower ends are all provided with
