Abstract

The utility model discloses a single shaft oval vibrating screen which comprises a single shaft circular vibrating screen. A screening plate is mounted in a single shaft circular vibrating screen body. Secondary oval vibrating springs are evenly arranged between a supporting base of the screening plate and the single shaft circular vibrating screen body. A coupling is mounted, outside the vibrating screen body, at one end of an adjustable eccentric block vibrating shaft which is mounted inside the vibrating screen body. A motor is connected with an outer end shaft of the coupling. Pedestals are respectively arranged below the motor and the vibrating screen body. Primary springs are mounted between the vibrating screen body pedestal and the vibrating screen body in a balanced mode. The screening plate is a stepped rod screening plate. Due to the fact that the coupling is a quincunx coupling. The vibrating screen body is driven to work by a group of single shaft vibrators and the vibrating locus of the screening plate turns into oval through the secondary springs at the same time, amplitude is increased two to three times, holes are prevented from being blocked, and screening efficiency is improved.

Description

A kind of single shaft elliptically vibrating screen

Technical field:

The utility model relates to screening plant, particularly a kind of single shaft elliptically vibrating screen that passes the raising screening efficiency of shaking by the spring secondary.

Background technology:

Existing elliptically vibrating screen all is to be the work of vibratory drive sieve nest with three or diaxon vibrator, has complex structure, and weight is big, energy consumption is high, the shortcoming of inconvenient maintenance.

Summary of the invention:

The purpose of this utility model provides a kind of simple in structure, single shaft elliptically vibrating screen in light weight, that energy consumption is low, easy to maintenance.

The technical solution of the utility model is finished as follows, a kind of single shaft elliptically vibrating screen, it includes a single shaft circular shale shaker, it is characterized in that: a sieve plate is installed in single shaft circular shale shaker sieve nest, symmetry is evenly equipped with the secondary elliptical vibrating spring between the supporting seat of sieve plate and sieve nest, one end of the adjustable eccentric block vibrating shaft of installing in sieve nest is equipped with shaft coupling outside sieve nest, be connected with a motor at the outer end of shaft coupling axle, be respectively equipped with base below motor and sieve nest, balance is equipped with spring one time between sieve nest base and sieve nest.Sieve plate is a kind of stairstepping rod sieve plate.Shaft coupling is a kind of quincunx shaft coupling

The utility model drives sieve nest work with one group of single shaft vibrator, and makes the sieve plate oscillation trajectory become ellipse by the secondary spring simultaneously, makes amplitude increase 2-3 doubly, has not only prevented plug-hole, and has improved screening efficiency.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

The specific embodiment:

Describe embodiment by reference to the accompanying drawings in detail, it comprises a single shaft elliptically vibrating screen, its improvements are that the rod sieve plate 1 that a stairstepping is arranged is installed in a single shaft circular shale shaker sieve nest 3, the uniform secondary elliptical vibrating spring 2 that is equipped with of symmetry between the supporting seat of rod sieve plate and sieve nest, one end of the adjustable eccentric block vibrating shaft of installing in sieve nest 6 is equipped with a quincunx shaft coupling 7 outside sieve nest, be connected with a motor 5 at the outer end of plum blossom shaft coupling axle, be respectively equipped with base below motor and sieve nest, balance is equipped with spring 4 one time between sieve nest base 8 and sieve nest.The utility model adopts one group of single shaft vibrator to make sieve nest that the vibration of circle track take place, and makes the vibration of sieve nest generation elliptical orbit by the secondary elliptical vibrating spring again.In secondary vibration, make the amplitude of sieve plate increase 2-3 doubly, reduced the plug-hole phenomenon greatly, improved screening efficiency.
