In particularly mining vibratory sieve field, vibratory sieve field, because the screen box vibration is strong, the easy spallation of support, and also because the quality of mineral is bigger, also bigger to the loss of sieve nest, noise is big, influences staff's physical and mental health; After using for a long time, sieve nest changes inconvenience; The electric energy that screening unit mass material is consumed is many, and this just requires a kind of appearance of the novel vibrating screen low, that vibration frequency is adjustable, noise is little that consumes energy.
Summary of the invention
The novel magnetic of problems such as the utility model provides a kind of can solve that ubiquitous noise is big, poor stability, power consumption height, efficient are low drives vibratory sieve.
The purpose of this utility model is achieved in that and comprises sieve nest below installation magnetic driving equipment, magnetic driving equipment provides power by motor, magnetic driving equipment and motor are fixed on the support jointly, it is characterized in that: on the driving shaft of magnetic driving equipment driving wheel is installed, a driving wheel arc rib shape magnet and a driving wheel arc magnet ring are housed on the driving wheel cambered surface, the outer protective cover of installing of driving shaft and driving wheel, the fixed-site expansion link of corresponding driving wheel on the protective cover, expansion link magnet is equipped with in the expansion link bottom, driving wheel arc rib shape magnet and driving wheel arc magnet ring homopolarity are outside, and all relative with expansion link magnet homopolarity, the magnetic force of driving wheel arc magnet ring is less than the magnetic force of driving wheel arc rib shape magnet; The connecting axle bottom is fixed in the expansion link, and the outer end is fixed on the sieve nest bottom.
The purpose of this utility model can also realize like this: driving wheel arc rib shape magnet and a driving wheel arc magnet ring are encircles shape, and two expansion link magnet also are in the expansion link bottom encircles shape.
Be the magnetic driving equipment of tandem installation more than two on the driving shaft, drive sieve nest jointly.
The beneficial effect that the utility model reaches is: the driven by motor driving shaft rotates the vibration can finish vibratory sieve, accomplishes to save energy and reduce the cost, reduces noise, amplitude is adjustable.

The specific embodiment
The label of parts shown in accompanying drawing title:
Magnetic driving equipment 1(driving shaft 1.1, driving wheel 1.2, driving wheel arc rib shape magnet 1.3, driving wheel arc magnet ring 1.4, protective cover 1.5, expansion link 1.6, expansion link magnet 1.7), sieve nest 2, support 3, connecting axle 4, motor 5.
Below in conjunction with description of drawings embodiment of the present utility model:
Shown in Fig. 1,3, magnetic driving equipment 1 and sieve nest 2, motor 5 are installed on the support 3, and wherein magnetic driving equipment is positioned at the below of sieve nest, and magnetic driving equipment 1 provides power by motor 5, and wherein sieve nest 2 is downward-sloping back to front.
As Fig. 3, shown in Figure 4, on the driving shaft 1.1 of magnetic driving equipment 1 driving wheel 1.2 is installed, a driving wheel arc rib shape magnet 1.3 and a driving wheel arc magnet ring 1.4 are housed on driving wheel 1.2 cambered surfaces, driving shaft 1.1 and the driving wheel 1.2 outer protective covers 1.5 of installing, the fixed-site expansion link 1.6 of corresponding driving wheel 1.2 on the protective cover 1.5, expansion link magnet 1.7 is equipped with in the expansion link bottom, driving wheel arc rib shape magnet 1.3 and driving wheel arc magnet ring 1.4 homopolarities are outside, and all relative with expansion link magnet 1.7 homopolarities, the magnetic force of driving wheel arc magnet ring 1.4 is less than the magnetic force of driving wheel arc rib shape magnet 1.3; Connecting axle 4 bottoms are fixed in the expansion link 1.6, and the outer end is fixed on sieve nest 2 bottoms.
Driving wheel arc rib shape magnet 1.3 and a driving wheel arc magnet ring 1.4 are encircles shape.
As shown in Figure 5, be the magnetic driving equipment 1 of tandem installation more than two on the driving shaft 1.1, drive sieve nest 2 jointly.
