Abstract

The utility model relates to a double-mass resonance type vibration screen which is characterized in that a vibrating motor is connected with a balancing frame by bolts, and the upper and the lower plane surfaces of the balancing frame are respectively connected with shear rubber springs on the upper and the lower surfaces; the shear rubber springs on the upper and the lower surfaces are respectively connected with press plates which are on the upper and the lower surfaces, and the press plate on the upper and the lower surfaces are respectively connected with a left and the right side plates by bolts; the left and the right side plates are connected with a vibrating screen body by bolts; a front and a back supporting seats are connected with the front and the back part of the screen bdy respectively by damping springs. Master vibration springs of the utility model adopt the shear rubber springs which has the damping effect as well as can transfer comparatively large exciting force. When the shear rubber springs are in operation, inertial force generated by the balancing frame and the vibrating screen body is driven by the shear rubber springs, and the screen body bearing overlarge dynamic stress and the balancing frame bearing overlarge acting force can be avoided. The utility model has the characteristics of no easy cracking of the screen body, little maintenance amount, long service life, small impact force, stable running low noise, etc.

Description

The resonant vibratory sieve of two plastids

Technical field:

The utility model belongs to a kind of pair of resonant vibratory sieve of plastid, is mainly used in industries such as metallurgy, coal, chemical industry, building materials are carried out classification, dehydration, de-mediated to bulk material screening field.

Background technology:

At present, in the bulk material screening plant of industries such as coal in China, metallurgy, building materials, chemical industry, the elemental body structures that adopt more, owing to the reason on its structural design, vibrating motor or eccentric shaft directly are connected with the vibration sieve nest, the exciting force that they produced just directly acts on the sieve nest, has therefore produced a series of disadvantages: shortcomings such as sieve nest bumpy motion, impulsive force is big, noise is big, sieve nest ftractures easily, maintenance capacity is big occur.

Summary of the invention:

The purpose of this utility model provides and a kind ofly operates steadily, impulsive force is little, noise is little, sieve nest is not easy to crack, long service life, the resonant vibratory sieve of two plastids that maintenance capacity is few.

For achieving the above object, the technical scheme that its technical problem that solves the utility model adopts is: a kind of pair of resonant vibratory sieve of plastid, involving vibrations motor 1, balancing stand 2, shear rubber spring 3, pressing plate 4, left side plate 5 and sieve nest 6, its technical characterictic is: vibrating motor 1 is connected with balancing stand 2 by bolt, the last lower plane of balancing stand 2 is connected with shearing rubber spring 3 respectively by bolt, the shearing rubber spring 3 of top and bottom is connected with the pressing plate 4 of top and bottom respectively by bolt, the pressing plate 4 of top and bottom is connected with left side plate 5 respectively by bolt, left side plate 5 is connected with vibration sieve nest 6 by bolt, and preceding bearing 7 is connected by the front and rear of shock-absorbing spring with sieve nest 6 respectively with rear support 8.

The beneficial effects of the utility model are against existing technologies: main vibration spring has adopted the design of shearing rubber spring, both had damping effect, can transmit bigger exciting force again, improved the service behaviour of vibratory sieve, overcome defective of the prior art, had and operate steadily, impulsive force is little, the sieve nest long service life, characteristics such as maintenance capacity is few, and noise is little.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is that the utility model A is to structural representation.

The specific embodiment:

Contrast Fig. 1-2, the resonant vibratory sieve of two plastids, by vibrating motor 1, balancing stand 2, shear rubber spring 3, pressing plate 4, left side plate 5 and sieve nest 6 constitute, its concrete structure is: vibrating motor 1 is connected with balancing stand 2 by bolt, the last lower plane of balancing stand 2 is connected with shearing rubber spring 3 respectively by bolt, on, below shearing rubber spring 3 by bolt respectively with last, following pressing plate 4 is connected, on, following pressing plate 4 is connected with left side plate 5 respectively by bolt, left side plate 5 is connected with sieve nest 6 by bolt, and preceding bearing 7 is connected by the front and rear of shock-absorbing spring with sieve nest 6 respectively with rear support 8.

The resonant operation principle of shaking sieve of the two plastids of the utility model is: after connecting power supply, the exciting force that is installed in vibrating motor 1 generation on the balancing stand 2 is by shearing rubber spring 3, pressing plate 4, left side plate 5 passes to vibration sieve nest 6, vibration sieve nest 6 is vibrated under the Near resonance oscillating state, finish the screening work of sieve nest.

Shear-type rubber spring 3 has the vibration isolation effect can transmit bigger exciting force again, and when work, it pins down The inertia force that balancing stand 2 and vibration sieve nest 6 produce has avoided sieve nest to bear excessive dynamic stress and balance Therefore frame 2 bears excessive active force, and it is not easy to crack to have a sieve nest, and maintenance capacity is few, and prolong service life, Operate steadily the characteristics such as noise is little.
