Said ballstone crowd checkout gear also comprises a voltage detecting sensor; Said the 3rd conduction carbon brush, said the 4th conduction carbon brush connect the input of said voltage detecting sensor respectively, and the signal output part of said voltage detecting sensor connects said signal processing module;
The other end of said detection head is fixed with the servo-actuated iron core, and said servo-actuated iron core is arranged on the below of said moving iron core, and has certain air gap, and said servo-actuated iron core rotates along with the rotation of said moving iron core.
8. ballstone group motion attitude distribution detection method according to claim 7 is characterized in that: be provided with one between said moving iron core and the said servo-actuated iron core and isolate lid, the employing of said isolation lid is nonmetal, non-magnet material is processed.
9. ballstone group motion attitude distribution detection method according to claim 8 is characterized in that: after coil feeds power supply, produce magnetic flux in moving core interior, constitute flux circuit by moving iron core, air gap, isolation lid, servo-actuated iron core; Do not have the ballstone group time in the ball mill body interior, the detection head projection is not hindered, and detection head and servo-actuated iron core freely rotate;
The moving iron core of driven by motor rotates, and the magnetic field of moving core interior drives the servo-actuated iron core and freely rotates, and the silicon steel sheet installation direction of moving iron core and the silicon steel sheet installation direction of servo-actuated iron core are consistent; Flux circuit is stable; Magnetic resistance is stable, and magnetic flux is constant, does not have induced potential to produce on the induction coil;
When the ball mill body interior has the ballstone group time, the detection head projection is hindered, and detection head and servo-actuated iron core can not freely rotate; The moving iron core of driven by motor rotates; The magnetic field of moving core interior can not drive the servo-actuated iron core and freely rotate; At this moment, the silicon steel sheet installation direction of moving iron core departs from the silicon steel sheet installation direction of servo-actuated iron core, and it is big that the flux circuit magnetic resistance becomes; When the silicon steel sheet installation direction of the silicon steel sheet installation direction of moving iron core and servo-actuated iron core is vertical, flux circuit magnetic resistance maximum;
When the servo-actuated iron core was hindered by the ballstone crowd in company with detection head, motor was still pressed certain frequency f uniform rotation under power drives, and moving iron core is by the frequency f uniform rotation; Flux circuit magnetic resistance size variation also clocklike changes by frequency f; Under the stable situation of supply voltage, the magnetic flux size of moving core interior also can clocklike change, and on induction coil, will induce the induced electromotive force that changes by frequency f; The voltage detecting sensor detects this induced electromotive force that changes by frequency f; And output to signal processing module, according to induced electromotive force life period and motor rotation time, judge ballstone crowd existence, the distribution of ball mill body interior.
10. ballstone group motion attitude distribution detection method according to claim 9; It is characterized in that: when ball mill main body operate as normal; The ball mill main body was rotated in the week; Induced electromotive force is zero on the induction coil, explains that detection head does not receive ballstone crowd's obstruction, and there is not the ballstone crowd in the ball mill body interior;
In the ball mill main body was rotated a week, induced electromotive force is zero a little while on the induction coil, and was non-vanishing a little while, explains that there is the ballstone crowd in the ball mill body interior; Rotate the time that induced electromotive force exists on time and the induction coil in a week according to the ball mill main body, judge the distribution situation of ballstone crowd in the ball mill body interior;
In the ball mill main body was rotated a week, induced electromotive force existed all the time on the induction coil, explained that ball mill main body rotating speed is too high, and the ballstone crowd is in apocarpy, or the ball mill body interior is full of the ballstone crowd.
