Description
Technical field
The utility model belongs to mining equipment field more particularly to the anti-blocking sieve bend of compass screen surface rapping.
Background technique
Sieve bend is chiefly used in separation of coarse slime, and concentrate initially enters the feed box of sieve bend, then drops down onto sieve using self weight
Sieve flows down on the net and arcuately, and the moisture in concentrate realizes separation through sieve.But in practical applications, due to workshop
The flow velocity of design and concentrate is too fast, and when production run, the screen slot of sieve bend will soon be blocked by concentrate, while sieve bend works
Feature is high-frequency low amplitude vibrations, limited for the excellent self-cleaning effect of screen slot blocking, and sieve bend compass screen surface is caused to be easy quickly paste
Firmly, dehydrating effect is seriously affected, causes coarse slime product quality abnormal, influences normal organization of production.
The prior art mainly adopts manually rapping compass screen surfaces, or drive vibrator to certain of sieve using exciting device
A little positions carry out an impact to solve the problems, such as that compass screen surface mesh paste is stifled, but method in the prior art has that structure is complicated, energy
Consume higher phenomenon.
Utility model content
The purpose of the utility model is to provide a kind of sieve bends that compass screen surface rapping is anti-blocking, and the utility model structure is simple, and one
It drives move to strike simultaneously with the upper and lower end to sieve more, quickly removes the blocking of compass screen surface mesh.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows:
The anti-blocking sieve bend of compass screen surface rapping, sieve nest, sieve including sieve bend and is set to above sieve at sieve nest
Central sill is each extended on the central sill along sieve both ends equipped with support arm, and support arm end and rapping arm middle section bottom are arranged
Supporting plate it is hinged, rapping arm one end is equipped with vibrator, and the other end connect with power mechanism, and vibrator is located at screen end surface
And with screen end Intermittent Contact.
Preferably, far from lifting lug is hingedly equipped at the top of one end of vibrator, the lifting lug of two rapping arms passes through the rapping arm
Connecting rod connection, connecting rod are parallel to central sill and connect with power mechanism.
Preferably, the power mechanism is the cylinder connecting with high-pressure air source, the hydraulic cylinder or electricity that connect with hydraulic oil unit
Dynamic push rod.
Preferably, the vibrator is cylindrical type rubber bar, and the rubber grain of evagination, rubber are densely covered on the outer wall of rubber bar
The outer diameter of glue particle is less than the mesh diameter of sieve.
Preferably, the rubber bar is axially sheathed on outside shaft, and shaft one end is equipped with defining flange, and the other end passes through solid
Fixed board is fixedly connected with rapping arm end.
The course of work of the utility model is as follows:
Power mechanism pushing tow connecting rod, connecting rod drives the end of two rapping arms to move up by lifting lug, due to rapping arm middle section
It is hinged with support arm by supporting plate, so the rapping arm other end moves down, vibrator is contacted into screen end, two vibrators are right respectively
The upper and lower end of sieve is struck, by the tamper on sieve mesh shake from.After completing primary impact, power mechanism is driven
Connecting rod moves down, and to strike on the arm other end and move to vibrator and separate with sieve.
Vibrator is rubber bar, has certain elasticity, can effectively buffer the anti-brisance generated when impact, and vibrator
With certain length, sieve can be struck with large area, block clearing works well.While it will do it circumferential direction when rubber bar and screen contact
It rolls, degree extruding is carried out to the compass screen surface touched, the rubber grain insertion portion mesh on rubber bar further realizes clear
It is stifled.
It about the frequency of rapping, can be adjusted by adjusting the driving frequency of power mechanism, if power mechanism is gas
When cylinder, it can be filtered using high-pressure blast by oil filter and enter central controlled solenoid valve, solenoid valve is executed by logical order
On-off action is controlled the state of cylinder by the high-pressure blast of solenoid valve, drives the connecting rod of cylinder, the end of connecting rod is that rubber bar is hit
Hammer, to realize that the impact of hammer carries out automatically.
The utility model compared with prior art, has the advantages that the utility model structure is simple, can drive simultaneously
Two impact arms strike the upper and lower end of sieve simultaneously, quickly remove the blocking of compass screen surface mesh.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the sieve bend that compass screen surface rapping is anti-blocking in specific embodiment.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1, the sieve bend that compass screen surface rapping is anti-blocking, sieve nest 7, sieve 6 including sieve bend and it is set to sieve 6
Central sill 1 at the sieve nest of top is each extended on the central sill 1 along sieve both ends equipped with support arm 11,11 end of support arm with
The supporting plate 21 of 2 middle section bottom of rapping arm setting is hinged, and 2 one end of rapping arm is equipped with vibrator, is hingedly equipped with lifting lug at the top of the other end
22, the lifting lug 22 of two rapping arms 2 is connected by connecting rod 3, and connecting rod 3 is parallel to central sill 1 and connect with power mechanism, and vibrator is located at
