Abstract

The utility model discloses an oscillating screen for completing multi-stage screening once, which is composed of a case, an oscillating motor, a screen bed, etc. The four corners of the screen bed are respectively provided with springs, and the springs are fixed on a support frame of the case; the screen bed is arranged in the case, a connecting board of the screen bed is connected with a base of the oscillating motor, and the oscillating motor is arranged on the upper side of the connecting board of the screen bed; the connecting board, a connecting arm, a screen band of the screen bed are welded into a rigid body, the screen mesh is connected with the connecting arm through a bolt in stratification, and the connecting board and the oscillating motor can be sealed by a rubber board on the base.

Description

Oscillating screen

The utility model relates to a kind of vibratory sieve of once finishing sizing screening, belongs to a kind of sorting machine.

The vibratory sieve that uses is that motor and casing are fixed together at present, and casing vibrates with sifting bed, and power consumption is big.Have only one deck screen cloth, charging too much and the foreign matter in the material easily pile up obstruction, influence is produced, vibrational loading strengthens, and shorten the service life of machinery, and noise is big, the transportation inconvenience.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and provides a kind of little for consumption, do not stop up, and noiselessness, convenient transportation once can be finished the vibratory sieve of sizing screening.

The purpose of this utility model is achieved in that it comprises sieve nest, vibrating motor, sifting bed, spring, sifting bed is made of screen cloth, sieve nation, linking arm, connecting plate, its four angles are respectively equipped with spring, spring is fixed on the support of casing, be positioned at the below of sifting bed, sifting bed places in the casing, the connecting plate of its sifting bed is connected with the base of vibrating motor, vibrating motor place the sifting bed connecting plate above, the connecting plate of sifting bed, linking arm, sieve nation are by being welded as a rigid body, and screen cloth layering and linking arm link together by bolt; Seal by the rubber slab on the casing between connecting plate and the vibrating motor.

The purpose of this utility model can also reach by following measure: excessive for the material that prevents to enter sifting bed, be provided with baffle plate at the feed end of sifting bed; Be convenient transportation, casing is a combined type, assembles during use again, and its coaming plate can be rubber slab, plank, also can be canvas etc.

The utility model has following advantage compared to existing technology:

1, because vibrating motor is fastened on the steel plate above the sifting bed, vibrating motor only drives the sifting bed vibration, thereby power consumption is little;

2, because sifting bed is soft the connection with casing, casing is rubber slab, plank or canvas, does not produce noise;

3, convenient transportation;

4, it can install the multilayer screen cloth, therefore can once finish multistage screening, goes back the detachable portion screen cloth when not needing classification and only stays individual layer to get final product.

The drawing of accompanying drawing is described as follows:

Accompanying drawing is a structural representation of the present utility model.

Among the figure: discharge groove (1), casing (2), linking arm (3), wide-meshed screen (4), fine screen mesh (5), sifting bed (6), vibrating motor (7), connecting plate (8), rubber slab (9), charging aperture (10), baffle plate (11), sieve nation (12), spring (13).

Embodiment describes the utility model in detail below in conjunction with (accompanying drawing): sifting bed is by screen cloth (4,5), sieve nation (12), linking arm (3), connecting plate (8) constitutes, its four jiaos are respectively equipped with spring (13), spring (13) can be the rigidity spring, it also can be rubber spring, with rubber spring is good, spring (13) is fixed on the support of casing (2), be positioned at the below of sifting bed (6), sifting bed (6) places in the casing (2), vibrating motor (7) is fixed by bolts on the connecting plate (8) of sifting bed, between seal by the rubber slab on the casing (9), connecting plate (8), linking arm (3), sieve nation (12) is by the synthetic rigid body of welding, screen cloth (4,5) layering and linking arm (3) link together by bolt, arrange up and down according to screen sizes, wide-meshed screen (4) is put on the fine screen mesh (5), how much being provided with of the mesh size of screen cloth and screen cloth according to the material specification size, charging aperture (10) end of sifting bed (6) is higher than discharge end, and be provided with baffle plate (11) at feed end, the below of sifting bed (6) discharge end is provided with discharge groove (1) and screen cloth (4,5) match, casing (2) coaming plate is made with rubber or plank or canvas, and its structure is arbitrarily dismounting of combined type.
