Its sieve mainly has stick, broach, round steel welding, steel sheet to punch a hole, polyurethane sieve etc. and the structure that traditional sieve sifter and sieve case vibrate together has been changed to the multifrequency sieve, adopts the independent sifter vibration of multistage and the motion mode that sieve case and frame do not vibrate, from the pan feeding mouth to discharge end multistage sifter independent vibration separately.

The existing repetition frequency sieve is driven by a motor to drive a vibration exciter to move through an end transmission combination, the vibration exciter is a coaxial vibration exciter, the motor drives a motor support, space is occupied, the end transmission is a vulnerable part, and the vibration exciter is inconvenient to maintain, so that the problem is solved by the aid of the external vibration exciter repetition frequency sieve.

SUMMERY OF THE UTILITY MODEL

For overcoming the problem that exists among the correlation technique, the embodiment of the utility model provides an external vibration exciter multifrequency sieve has solved present multifrequency sieve cost higher, overhauls inconvenient problem.

The embodiment of the utility model provides an external vibration exciter multifrequency sieve, including sieve case, sieve core, blanking fill, collet, drive assembly, motor and vibration exciter, the slope of sieve case sets up on the collet, and the inside of sieve case is provided with the sieve core, still is provided with three drive assembly of group on the collet respectively, and drive assembly includes two vibration exciters and a motor, still is provided with drive assembly on the sieve case, and the sieve core sets up on drive assembly, and two vibration exciters pass through drive assembly and connect, and the output shaft of motor runs through the sieve case through the shaft coupling and is connected with drive assembly, the bottom of sieve case is provided with the blanking fill.

Further, the collet includes bottom plate, pillar and swash plate, installs the pillar on the bottom plate, and the swash plate is installed at the top of pillar, and the swash plate is connected with the sieve case.

Further, still be provided with the vibration exciter connecting seat between vibration exciter and the sieve case, the vibration exciter connecting seat is connected with the vibration exciter.

Further, the motor adopts double-end motor, and double-end motor sets up on the sieve case bracket with the vibration exciter jointly.

Furthermore, a spring for damping is further installed on the bottom support and connected with the vibration exciter.

The embodiment of the utility model provides a technical scheme has following beneficial effect: through the use drive of double-end motor, need not special design motor support, the sieve case bracket is used with the vibration exciter to the motor, has reduced equipment cost of manufacture, and occupation of land space overhauls and changes the convenience.
