Abstract

The utility model relates to a material separation machine, in particular to a vibrating screen. The vibrating screen comprises a material collection box, a vibration motor and a screen body, wherein the vibration motor and the screen body are arranged in the material collection box; the middle of the bottom of the material collection box is provided with a rotary table; the rotary table is in a tower-shaped structure; one end of the screen body is fixedly arranged on the rotary table; the outer edge of the other end of the screen body is movably connected to the inner side surface of the material collection box via a bearing; the screen body is in an inverse cone shape. After the above structure is adopted, the rotary table arranged on the screen body drives the vibrating screen body to rotate; because the rotary table is driven by a servo motor, the alternating motion of the forward and backward rotation of the screen body is realized, so that materials blocking the screen body fall under the action of inertia, the production efficiency is greatly improved, and the vibrating screen is suitable to be vigorously promoted; filtering can be more precisely carried out by screen bodies with meshes of different sizes, and various types of products can be filtered; an anti-vibration device arranged on the bottom of the material collection box is used for lowering noise while the device is better protected; a certain guarantee is provided for the body health of operation personnel.

Description

A kind of vibratory sieve

Technical field

The utility model 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 utility model technical issues that need to address 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 utility model 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 utility model is described in further detail.

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

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 utility model 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.
