Description

A kind of automatically cleaning vibration screen of building castoff screening machine

Technical field

It the utility model is related to a kind of vibration screen, the automatically cleaning vibration of specifically a kind of building castoff screening machine Screen cloth.

Background technology

Screening machine is the relative motion using bulk granular material and compass screen surface, partial particulate is passed through sieve aperture, by sand, gravel, broken The materials such as stone are divided into the vibration screening machinery equipment of different stage by granular size.In the recovery crushing and screening work of building castoff In work, the vibration screen of screening machine carries screening of gathering materials, determines the important function of grading.The crushing and screening mistake of building castoff Cheng Zhonghui produces substantial amounts of dust, after most enterprises selection at present carries out spray moistening to building castoff in advance, then carries out Crushing and screening produces, and so as to solve the problems, such as that airborne dust is excessive, but caused moistening fine powder easily blocking vibration sieves after crushing The less vibration screen of the square hole of net, particularly aperture, because traditional vibration screen is simple in construction, it is impossible in vibration processes Realize self-cleaning function, it is often necessary to shut down and carry out manually percussion or draping, can just continue production operation, so as to influence The production efficiency of enterprise, adds production cost.

Occur a kind of vibration screen for carrying and tapping hammer at present, during vibration screen vibratory sieve material, tap hammer Percussion vibration screen cloth can be constantly swung, so as to reach self-cleaning purpose, but this self-cleaning vibration screen has certain lack Point, over time, tap position that hammer swings because get rusty, soil impurity etc. and block master, causing to tap hammer to swing, and lose Tap function and make it is local can not complete automatically cleaning, moreover, the area at automatically cleaning position is smaller, tap position that hammer taps from clear Clean effect is preferable, and other positions then or easily block, and cause vibration screen automatically cleaning uneven, influences overall blanking effect Fruit.

Utility model content

To solve the above problems, the purpose of this utility model is to provide a kind of automatically cleaning vibration of building castoff screening machine Screen cloth.

The utility model to achieve the above object, a kind of automatically cleaning vibration screen of building castoff screening machine, including four The framework of side shape equally leaves opening with fixed plate of the framework up and down in two openings, the middle part of fixed plate is covered in, its Covered with screen cloth in the opening of middle top fixed plate, it is respectively fixed with the top two sides of lower mounting plate multigroup symmetrical Bottom spring anchor block, it is connected and fixed to form brush by a plurality of bristle fix bar being parallel to each other between two fixed strips Hair oscillating grid, the bristle oscillating grid of formation are arranged in the framework below screen cloth, and the downside of every fixed strip is set respectively Put number and spring anchor block at the top of the spring anchor block identical of bottom, and the bottom spring anchor block position that each two is symmetrical Centre between two symmetrical top spring anchor blocks, adjacent top spring anchor block are consolidated with bottom spring Determine to be fixedly connected by spring respectively between block, make bristle oscillating grid by every spring supporting inside framework, so when When framework is arranged on inside screening machine, bristle oscillating grid can also be vibrated with the vibration of framework, and every bristle is fixed The upper side of bar is respectively arranged with the bristle with screen contact, and the vibration of bristle oscillating grid will drive the continuous brush of bristle back and forth Screen cloth, screen cloth is set constantly to carry out automatically cleaning when screening, when the length of bristle fix bar is more than the width of screen cloth, and And bristle fix bar number meets, the bristle that the amplitude of swinging back and forth of spring can just make to swipe back and forth during vibration covers sieve Net, so carries out comprehensive automatically cleaning to screen cloth, and the effect of cleaning is more preferable.

Due to using above technical scheme, spring of the present utility model can be antirust treatment, conventional main side on surface Formula has：1. antirust oil processing；2. electroplate, such as zinc-plated, Cr；3. anticorrosive paint；4. blackening process etc., so make spring more resistant to With, and then service life long enough of the present utility model can be fully ensured that, bristle brush screen cloth is driven by the vibration of screening machine, Whole screen cloth can effectively be completely covered, not only make screen cloth self-cleaning uniformly comprehensively, and more thoroughly, be truly realized screen cloth Automatically cleaning.

Embodiment

As Figure 1-4, a kind of automatically cleaning vibration screen of building castoff screening machine, the He of framework 1 of quadrangle is included Fixed plate 2 of the framework up and down in two openings is covered in, opening is equally left in the middle part of fixed plate 2, wherein top is fixed Covered with screen cloth 3 in the opening of plate 2, multigroup symmetrical bottom bullet is respectively fixed with the top two sides of lower mounting plate 2 Spring fixed block 4, it is connected and fixed to form bristle by a plurality of bristle fix bar 6 being parallel to each other between two fixed strips 5 Oscillating grid, the bristle oscillating grid of formation are arranged in the framework 1 of the lower section of screen cloth 3, and the downside of every fixed strip 5 is set respectively Number and spring anchor block 7 at the top of the identical of bottom spring anchor block 4 are put, every piece of bottom spring anchor block 4 is obliquely installed respectively, And adjacent symmetrical bottom spring anchor block 4 is arranged in splayed, every piece of top spring anchor block 7 is equally tilted and set respectively Put, and two neighboring symmetrical top spring anchor block 7 is equally arranged in splayed, every piece of top spring anchor block 7 Spring 8 between the top of bottom spring anchor block 4, adjacent top spring anchor block 7 and bottom spring anchor block 4 tilts Setting, the upper end of spring 8 is fixed on the spring anchor block 7 of top, and the lower end of spring 8 is then fixed on bottom spring anchor block 4, Make two adjacent springs symmetrical, and the arrangement that is in the shape of the letter V, bristle oscillating grid is supported on framework 1 by every spring 8 Inside, every spring 8 can be suitably slightly compressed, and so formed by the spring 8 of both direction obliquely and bristle is shaken One upward support force of dynamic grid, when being easy to vibration, no matter the spring 8 of each side shrinks or extended, and can make bristle 9 Contacted with screen cloth 3, ensure that bristle 9 can comprehensively brush screen cloth 3；The upper side of every bristle fix bar 6 is respectively arranged with and sieved The bristle 9 that net 3 contacts, the bottom of bristle 9 is in the bristle stator 10 of the upper side of bristle fix bar 6, and bristle is fixed Piece 10 is fixed by screws in bristle fix bar 6, comparatively bristle 9 is easily-consumed products, and so design is conveniently replaceable bristle 9, Advantageously ensure that vibration screen overall service life；The a plurality of vertical top cross-section of bristle 9 in every bristle fix bar 6 is Triangle, and the top of bristle 9 most long in every bristle fix bar 6 is exposed at outside the upper surface of screen cloth 3, in every bristle fix bar 6 Then with the lower surface of screen cloth 3 in same level, the top of bristle 9 of such different length can touch on the most short top of bristle 9 The upper and lower surface of screen cloth 3, makes the two sides of screen cloth 3 can obtain brushing, realizes the automatically cleaning on two sides, and cleaning effect is more preferable.

Certainly, it is to limitation of the present utility model that described above, which is not, and the utility model is also not limited to the example above, this The those of ordinary skill of technical field, in essential scope of the present utility model, change, change, addition or the replacement made, all The scope of protection of the utility model should be belonged to.
