Description

Electro-vibrating feeder

The utility model relates to a kind of dosing equipment that can evenly be fed to loose bulk, graininess and granular material continuously feeding equipment from bin stock warehouse or funnel, relates in particular to a kind of electromagnetic oscillation device of dosing equipment.

Most electromagnetic oscillation devices all adopts the leaf spring structure in the dosing equipment commonly used at present, it is the elastic system of the directed forced vibration of two particles, quality such as 10-20% by material in hopper, coupling yoke, armature and the hopper are formed particle M1, form particle M2 by vibrator housing, iron core, coil etc., these two particles of M1 and M2 are associated in together by a branch of leaf spring plate, form a directed elastic system of two particles, the electromagnetic oscillation device of this structure is owing to there is following shortcoming in the defective in its design.

1, build is big, heavy: owing to adopt the leaf spring structure.The big and Heavy Weight of build because of laminated spring causes the bodily form of whole electromagnetic oscillation device big and heavy;

2, maintenance difficult: because laminated spring often damages, both be difficult for finding out the laminated spring that has damaged when maintenance, and just can have exchanged the alternative laminated spring that has decreased ring of new laminated spring after it all must being laid down for, it is very inconvenient to keep in repair;

3, can not guarantee normal air gap between armature and the iron core: because armature and iron core are respectively on a particle, artificial being difficult to adjusted to its required accurate air gap distance with it during assembling, i.e. 2.8 ± 0.30mm, so, often cause that watt loss is big to be reduced or cause short circuit because of air gap is too small relatively with yield of unit time because of air gap is excessive, cause coil burnout, thereby influence is produced;

4, because the hook that the mounting means of the electromagnetic oscillation device of leaf spring adopts is distributed on the cell body and electromagnetic shaker on, cause the parallelism between armature and the iron core poor.

In addition, this electromagnetic oscillation device causes cost higher and processing technology is complicated because of adopting leaf spring.

The purpose of this utility model be to overcome above-mentioned the deficiencies in the prior art and provide a kind of adopt small, in light weight, cost is low, easy to process, easy to maintenance and can fully guarantee normal air gap between armature and the iron core, i.e. the dosing equipment of the electromagnetic oscillation device of 2.8 ± 0.30mm.

The purpose of this utility model is achieved in that

The utility model is by shock absorber, feeder trough, electromagnetic shaker and controller are formed, electromagnetic shaker is fixed in the lower end of cell body, wherein the two ends of the coil on the iron core link to each other with controller, feeder trough passes through two damper mountings on support, wherein electromagnetic shaker is also by the seat that shakes, spiral pillar main spring, spiral pillar auxiliary spring, screw mandrel, spring cover, counterweight is formed, iron core is fixed on the support, armature is fixed in the lower end of the seat that shakes, counterweight is fixed in the upper end of the seat that shakes, at support with shake and be fixed with two main springs between the seat, on the seat that shakes, be fixed with two auxiliary springs, be crimped with two spring covers on two auxiliary springs respectively, two parallel and pass support respectively successively perpendicular to the screw mandrel on the last plane of support, main spring, seat shakes, auxiliary spring, an end all is fixed on the support behind the spring cover.The other end all is fixed on the spring cover, two rhizoid bars fuse support, the seat that shakes, spring cover, and make iron core and armature over against, and making the distance between iron core and the armature is 2.8 ± 0.30mm, and the seat that guarantees to shake only produces displacement in the direction perpendicular to support, and can not produce displacement being parallel on the direction of support.

Principle of work of the present utility model is as follows: the utility model is by the quality constituent particle M1 such as 15-23% of the object in feeder trough, support, iron core and the feeder trough; By the seat that shakes, counterweight, armature constituent particle M2, two particles adopt spiral pillar main spring to be connected into one, form a two particle directional vibration system.

Same as the prior art, the electric current of the magnet coil of electromagnetic oscillation device is through single phase half wave rectification, when the positive half cycle of energized, there is electric current to pass through in the coil, between armature and iron core, just produce pulse-electromagnetic force, attract each other, drive feeder trough and move backward, main spring is deformed and stored certain potential energy; And during the energized negative half period in the coil no current pass through, electromagnetic force disappears, because main spring recovers shape and discharges its potential energy, make the armature bullet from iron core, feeder trough promptly travels forward, and like this, feeder trough is just with the frequencies omega crank motion of source of AC, because the baseplane of feeder trough and the disturbance force active line of electromagnetic oscillation device have certain included angle, this just makes the material in the feeder trough continuously travel forward by predetermined parabolic path.

The utility model compared with prior art has following advantage:

Because the utility model has adopted spiral pillar main spring and auxiliary spring to replace leaf spring,, alleviated the weight of electromagnetic oscillation device and greatly reduce manufacturing cost and simplified production technology so dwindled the volume of electromagnetic oscillation device greatly; In addition, seat fuses with support owing to shake, so can guarantee size of gaps between iron core and the armature within 2.8 ± 0.30mm, and change the size of its air gap can not assemble the time, thereby avoid big, yield poorly or short circuited phenomenon takes place because of the excessive or too small energy consumption that causes of air gap because of it; In addition, owing to adopted spiral pillar main spring,, thereby make maintenance very convenient even if, also can change new main spring very easily when working because of main spring damages.

Below in conjunction with drawings and Examples the utility model is described in further detail:
