Abstract

The utility model discloses a vibrating screen comprising a vibrating screen body and a cross beam fixedly arranged at the upper portion of the vibrating screen body. A suspension type vibrating screen support is arranged on the inner side of the vibrating screen body. At least one layer of screen cloth is fixedly arranged on the vibrating screen body. The cross beam is provided with a vibration motor used for driving the vibrating screen support to conduct vertical reciprocating motion. Due to the fact that the vibration motor is used for replacing an original eccentric shaft, not only is stable control achieved and is the vibration effect better, but also the trouble that lubricating oil needs to be added frequently and the abraded eccentric shaft is replaced frequently can be avoided.

Description

A kind of vibratory sieve

Technical field

The utility model relates to a kind of vibratory sieve.

Background technology

Vibratory sieve of the prior art, the involving vibrations sieve nest, be fixedly installed on the crossbeam on described vibration sieve nest top, the inboard of described vibration sieve nest is provided with suspended vibration sieve support, be fixedly installed at least one deck screen cloth on described bracket for vibrating screen, usually driving bracket for vibrating screen to be pumped drives by eccentric shaft and drive motors, adopt aforesaid way, not only need the user often to the eccentric shaft apply oil, and eccentric shaft very easily weares and teares, service life is shorter, need to change in time, operate more inconveniently, and vibrating effect is poor.

The utility model content

The purpose of this utility model is to overcome the defect existed in prior art, and a kind of vibratory sieve is provided, and not only vibrating effect is good, and saves the eccentric shaft that adds lubricating oil and change wearing and tearing.

For achieving the above object, the technical solution of the utility model has been to provide a kind of vibratory sieve, the involving vibrations sieve nest, be fixedly installed on the crossbeam on described vibration sieve nest top, the inboard of described vibration sieve nest is provided with suspended vibration sieve support, be fixedly installed at least one deck screen cloth on described bracket for vibrating screen, be provided with the vibrating motor that drives described bracket for vibrating screen to pump on described crossbeam.

As preferably, described vibrating motor is the frequency-changing adjustable vibrating motor.

As preferably, between the two ends of described bracket for vibrating screen and described vibration sieve nest, be provided with elastic supporting member for supporting optical member.

As preferably, described bracket for vibrating screen tilts setting along throughput direction and the horizontal plane of material.

Advantage of the present utility model and beneficial effect are: replace original eccentric shaft by using vibrating motor, not only can reach and control steadily, vibrating effect is better, and can be without the trouble of often adding lubricating oil and often changing the eccentric shaft of wearing and tearing.

The accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

In figure: 1, vibration sieve nest; 2, crossbeam; 3, bracket for vibrating screen; 4, vibrating motor; 5, elastic supporting member for supporting optical member.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

As shown in Figure 1, a kind of vibratory sieve, involving vibrations sieve nest 1, be fixedly installed on the crossbeam 2 on described vibration sieve nest 1 top, the inboard of described vibration sieve nest 1 is provided with suspended vibration sieve support 3, be fixedly installed at least one deck screen cloth on described bracket for vibrating screen 3, be provided with the vibrating motor 4 that drives described bracket for vibrating screen 3 to pump on described crossbeam 2.

In the present embodiment, as technical scheme preferably, described vibrating motor 4 is frequency-changing adjustable vibrating motor 4.Can then regulate its vibration velocity by regulating the frequency of vibrating motor 4, meet the demand of different product, the scope of application is wider.

In the present embodiment, as technical scheme preferably, as shown in Figure 1, between the two ends of described bracket for vibrating screen 3 and described vibration sieve nest 1, be provided with elastic supporting member for supporting optical member 5.Elastic supporting member for supporting optical member 5 can be helical spring, by the elastic force of elastic supporting member for supporting optical member 5, makes bracket for vibrating screen 3 reset.

In the present embodiment, as technical scheme preferably, as shown in Figure 1, described bracket for vibrating screen 3 tilts setting along throughput direction and the horizontal plane of material, by bracket for vibrating screen 3 is obliquely installed, the output of the material after being convenient to be screened, material can utilize the gravity of self to glide along it.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
