Description
Technical field
The utility model relates to vibratory sieve machinery field, relates to the stronger tilting linear vibrating screen of a kind of load-bearing capacity specifically.
Background technology
At present particle, powder and thing grain are sieved, and distinguish the different-grain diameter range materials, be mostly to adopt the linear vibration sieve.Its operation principle is to provide the vibrating motor of vibration source to tilt 45 ° to be installed on the vibratory sieve support girder by two; In the even operation process of motor, form and support the vertical upper and lower vibration force of girder, owing to it is supported on the spring; So force direction is upper and lower beats along receiving to drive whole box body; Be contained in the material in the casing, comprise screening and unsized and particle, all along continuous straight runs is made parabolic motion.Thereby reach the purpose of material being sieved and material is transported to by import outlet.
At some special occasions; Need both material to be sieved, also material is carried, this moment, the power source of linear vibration sieve generally was to be provided by the vibrating motor that linear vibration sieves; Mounting means is generally level and installs, and load is general equal in the running can reach designed capacity.But in the real process, because of the instantaneous mass amount is very big, far surpass its designed capacity, cause material to block whole thickness Flow of Goods and Materials space, material can't normally be made parabola and flow and advance, and whole Flow of Goods and Materials process ends to cause the material sieve that overflows.
Like the patent No. is CN201020649891.0; The applying date is 2010-11-30; Name is called the utility model patent of " herringbone compass screen surface linear vibrating screen "; Its technical scheme is: the herringbone compass screen surface that a kind of herringbone compass screen surface linear vibrating screen is made up of two parts compass screen surface, be installed on the screen frame, and the intersection of two parts compass screen surface is positioned at the upper position in the middle of the vibratory sieve screen frame; Screen frame is installed on the vibration damping support device; Under the herringbone compass screen surface intersection or on two side plates of screen frame, the vibrating motor or the vibrator of straight-line oscillation track is installed.The force action line that vibrator produces is parallel with horizontal plane, makes screen frame form the straight-line oscillation track parallel with horizontal plane with the herringbone compass screen surface.Though above-mentioned patent has been made architecture advances to the structure and the vibrator of vibratory sieve, when feed was inhomogeneous, often the far ultra designed capacity of instantaneous load caused the excessive sieve of material and the not smooth phenomenon of discharging occurs still not to be resolved.
Summary of the invention
Because existing linear vibrating screen exists when feed is inhomogeneous, often the far ultra designed capacity of instantaneous load causes the excessive sieve of material and the not smooth problem of discharging occurs, the existing special tilting linear vibrating screen that the change structure is less, load-bearing capacity strengthens that proposes.
For realizing above-mentioned purpose, the technical scheme of the utility model is following:
A kind of tilting linear vibrating screen comprises casing and the material-homogenating device that is arranged on casing one end, and casing other end opening is provided with thin material outlet and Coarse Aggregate outlet, is provided with sieve plate at box house; The material-homogenating device end and the port of export at casing are provided with bracing frame, it is characterized in that: said bracing frame near the material-homogenating device end has been provided with the oblique cushion block of bed hedgehopping bracing frame function of height, and said bracing frame near the port of export also is provided with oblique cushion block.
Said casing outer setting has contiguous block, and contiguous block is provided with support spring, and support spring is arranged with damping spring, and damping spring links to each other with casing, and the damping spring below is provided with oblique cushion block.
Oblique cushion block height on the bracing frame of said material-homogenating device end is higher than the oblique cushion block on the port of export bracing frame, and two oblique cushion blocks make that screen cloth run-off the straight, angle of inclination are 3-8 °.
Said vibrating motor is two.
The advantage of the utility model is:
Changing under the few prerequisite of existing Structure of Vibrating Screen, effectively increase it and sieve and conveying capacity, especially when instantaneous load surpasses rated capacity 20-30%, all can guarantee normal operation.

Fig. 2 is the utility model side view.
In the accompanying drawing 1, casing 2, material-homogenating device 3, thin material outlet 4, Coarse Aggregate outlet 5, sieve plate 6, bracing frame 7, oblique cushion block 8, contiguous block 9, support spring 10, damping spring 11, vibrating motor.
The specific embodiment
The tilting linear vibrating screen comprises casing and the material-homogenating device that is arranged on casing one end, and casing other end opening is provided with thin material outlet and Coarse Aggregate outlet, is provided with sieve plate at box house; The material-homogenating device end and the port of export at casing are provided with bracing frame, and said bracing frame near the material-homogenating device end has been provided with the oblique cushion block of bed hedgehopping bracing frame function of height, and said bracing frame near the port of export also is provided with oblique cushion block.The casing outer setting has contiguous block, and contiguous block is provided with support spring, and support spring is arranged with damping spring, and damping spring links to each other with casing, and the damping spring below is provided with oblique cushion block.Oblique cushion block height on the bracing frame of material-homogenating device end is higher than the oblique cushion block on the port of export bracing frame, and two oblique cushion blocks make that screen cloth run-off the straight, angle of inclination are 3-8 °, and vibrating motor is two.
Before the change, material only receives the up-down vibration power of vibrating motor, and material is advanced as parabola.After the change, not only receive the effect of vibration force, also increased a component G*sin a of material gravity this moment.This power helps material flowing to Way out greatly.Thereby increased the conveying capacity of material.The change angular range is selected: this type vibratory sieve, because the front and back span is general all more than 3m, so the angle of inclination is unsuitable excessive, generally range of choice is 3-8 ° and is advisable, and present embodiment is adopted as 3.75 °.During parallel installation, support spring only receives the up-down vibration power of vibration source, the effect of casing gravity, and vibratory sieve is in very stable state.Excessive like the oblique angle, casing deadweight, material gravity; The component of exciting force all has a component towards the discharging direction, and the inclination angle is big more, and this component is just big more; And the application point of power constantly moves to Way out with the inclination angle increase, and when it exceeded the spring supporting surface, this vibratory sieve will topple; And angle is excessive, and the input and output material end raises and reduces a lot, is not easy to the installation of apparatus for feeding and discharging feeding equipment.So angle is unsuitable excessive.
Mixed material, is made parabolic by the material-homogenating device end to the material outlet end and is flowed under the vibration force effect of vibrating motor through being evenly distributed on behind the material-homogenating device on the bar shaped sieve plate.In the motion process, material constantly obtains screening, and fine leaks down through the space of bar shaped sieve plate, gets into the bottom of casing, and coarse-grained material is all the time on the top of sieve plate.All under the effect of vibration force and material partical gravity, that does not stop is moved to discharge end by feed end the upper and lower part material.Move to behind the port of export by different discharge hole for discharge.Thereby reach the purpose that material sieves.
