Abstract

The invention relates to a material separation machine, in particular to a vibrating screen. The vibrating screen comprises a material collecting box, a vibrating motor and a screen body, wherein the vibrating motor and the screen body are arranged inside the material collecting box. A rotary table is arranged in the midpoint of the bottom of the material collecting box, the rotary table is of a tower-type structure, one end of the screen body is fixed to the rotary table, the outer edge of the other end of the screen body is movably connected to the inner lateral side of the material collecting box through bearings, and the screen body is in an inverse-cone shape. By means of the structure, the screen body in vibrating is driven by the rotary table arranged on the screen body to rotate, the rotary table is driven by a servo motor, alternating movement of forward rotation and backward rotation of the screen body is achieved, materials blocking the screen body fall off under the effect of inertia, the production efficiency is greatly improved, and the vibrating screen is suitable for being energetically promoted; the screen body with meshes in different sizes is arranged, filtering is accurately carried out, and filtering-processing products have the diversity; an anti-vibration device is arranged at the bottom of the material collecting box, the vibrating screen is well protected, meanwhile, noise is lowered, and certain guarantees are provided for health of operators.

Description

A kind of vibratory sieve

Technical field

The present invention relates to a kind of feed separation machinery, particularly a kind of vibratory sieve.

Background technology

Screening is divided into equal-sized different particle group solid particle exactly, and vibratory sieve is to reach by vibration the device that sieves out required granularity material.In prior art, most of vibratory sieve working portions maintain static, and by material, along working face, slide and material is sieved, and structure is relatively simple, easily manufactured, but production efficiency is low, screening efficiency is low, generally only has 50-60%, also easily stop up sieve aperture, to production, caused great trouble.

Summary of the invention

The technical issues that need to address of the present invention are to provide a kind of vibratory sieve, and this vibratory sieve can farthest be avoided sieve pore blockade, simple in structure, suitable wideling popularize.

For solving above-mentioned technical problem, a kind of vibratory sieve of the present invention comprises Material collecting box for harvesting, is located at vibrating motor and sieve nest in Material collecting box for harvesting; Middle, described Material collecting box for harvesting bottom is provided with turntable, and turntable is electrically connected to servomotor; One end of described sieve nest is fixed on bearing, and the other end outer edge of sieve nest is movably connected on Material collecting box for harvesting medial surface by bearing, and described sieve nest is inverted cone-shaped; Described bearing is fixed on turntable.

Further, described Material collecting box for harvesting is placed on pedestal, between Material collecting box for harvesting and pedestal, is fixed with antihunting device, and described antihunting device is spring.

Further, described bearing is hierachical structure, and bearing is between layers for being threaded, and described sieve nest is multilayer screen cloth, and wherein, one deck screen cloth is fixed on one deck turntable.

Further, the quantity of described screen cloth is 2～4.

Further, the angle on described bearing hypotenuse and ground is 45 degree～60 degree.

Further, the angle on described bearing hypotenuse and ground is 50 degree.

Adopt after said structure, by the turntable of being located on sieve nest, drive sieve nest in vibration to rotate, and be servomotor due to what drive turntable, realized the alternating movement of sieve nest rotating, make the material that stops up sieve nest fall under the effect of inertia, greatly improved production efficiency, and simple in structure, with low cost, suitable wideling popularize; By the sieve nest of different width of mesh, make to filter more accurately, the product of filtration treatment has more diversity; By being located at the antihunting device of Material collecting box for harvesting bottom, in protective device, lowering noise better, be operating personnel's the healthy certain guarantee that provides.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

Fig. 1 is internal structure schematic diagram of the present invention.

In figure: 1 is Material collecting box for harvesting, 2 is sieve nest, and 3 is bearing, and 4 is bearing, and 5 is turntable, and 6 is antihunting device, and 7 is pedestal

The specific embodiment

As shown in Figure 1, a kind of vibratory sieve of the present invention comprises Material collecting box for harvesting 1, is located at vibrating motor and sieve nest 2 in Material collecting box for harvesting 1; Described Material collecting box for harvesting 1 middle, bottom is provided with turntable 5, and turntable 5 is electrically connected to servomotor; One end of described sieve nest 2 is fixed on bearing 4, and the other end outer edge of sieve nest 2 is movably connected on Material collecting box for harvesting 1 medial surface by bearing 3, and described sieve nest 2 is inverted cone-shaped; Described bearing 4 is fixed on turntable 5.By the turntable 5 of being located on sieve nest 2, drive sieve nest 2 rotations in vibration, and be servomotor due to what drive turntable 5, realized the alternating movement of sieve nest 2 rotatings, make the material that stops up sieve nest 2 fall under the effect of inertia, greatly improved production efficiency, and simple in structure, with low cost, suitable wideling popularize

Further, described Material collecting box for harvesting 1 is placed on pedestal 7, between Material collecting box for harvesting 1 and pedestal 7, is fixed with antihunting device 6, and described antihunting device 6 is spring, is lowering noise better in protective device, is operating personnel's the healthy certain guarantee that provides.

Further, described bearing 4 is hierachical structure, and bearing 4 is between layers for being threaded, and described sieve nest 2 is multilayer screen cloth, and wherein, one deck screen cloth is fixed on one deck turntable.

Further, the quantity of described screen cloth is 2～4.

Further, the angle on described bearing 4 hypotenuses and ground is 45 degree～60 degree, and such angle can fall material smoothly between each screen cloth, for not causing the accumulation of bottom material, has improved production efficiency.

Further, the angle on described bearing 4 hypotenuses and ground is 50 degree.
