Description
Technical field
The utility model relates to a kind of probability screen, relates in particular to a kind of damping type probability screen.
Background technology
China has produced ZGS series motor synchronizing probability screen at present.This sieve is to be counter-rotated by two vibrating motors, the out-of-balance force (inertia force) producing due to the eccentric mass at motor two ends orders about screen(ing) machine and makes double vibrations by certain orientation, the relative compass screen surface of two motor shafts has an inclination angle in the vertical direction, at exciting force and material under the force action of gravity, material is tossed jump or moving linearly forward on compass screen surface, thereby reach, material is screened and the object of classification.But this mechanical shock absorption is an important job.
Utility model content
For the problems referred to above, the utility model provides a kind of damping type probability screen.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of damping type probability screen is provided, its structure is by shock-damping structure, screen(ing) machine body and frame composition, described shock-damping structure comprises damping spring, wire tensioner and steel wire rope, described screen(ing) machine body comprises screen box, vibrating motor and the compass screen surface that is arranged on screen box inside, described steel wire rope is connecting damping spring from top to bottom successively, wire tensioner is hung in screen(ing) machine body on support, described compass screen surface is divided into three layers, be divided into upper sieve plate from top to bottom, middle sieve plate and lower sieve plate, described upper sieve plate, between crossbeam in middle sieve plate and lower sieve plate and screen box, be provided with the rubber slab of 6mm.
Further, described damping spring is installed in frame, and described vibrating motor is bolted and is arranged on screen box.
Further, between screen box and coal spout, be connected with screw with nylon canvas.
From the above-mentioned description to the utility model structure, compared to the prior art, the utlity model has following advantage:
1, the utility model adopts hanging depressurized system, and by damping spring, wire tensioner and steel wire rope are hung in screen(ing) machine body on support by rope clamp, and spring plays damping and does use.
2, between the crossbeam in upper sieve plate, middle sieve plate and lower sieve plate and screen box, be provided with the rubber slab of 6mm, between screen box and coal spout, be connected with screw with nylon canvas, improve the service life of screen(ing) machine.
Brief description of the drawings
The accompanying drawing that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is a kind of damping type probability screen of the utility model structure diagram;
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
By reference to Fig. 1, its structure is by shock-damping structure, screen(ing) machine body and frame 9 form, described shock-damping structure comprises damping spring 1, wire tensioner 2 and steel wire rope 3, described screen(ing) machine body comprises screen box 8, vibrating motor 7 and the compass screen surface that is arranged on screen box 8 inside, described steel wire rope 3 is connecting damping spring 1 from top to bottom successively, wire tensioner 2 is hung on support 9 by screen(ing) machine body, described compass screen surface is divided into three layers, be divided into upper sieve plate 4 from top to bottom, middle sieve plate 5 and lower sieve plate 6, described upper sieve plate 4, between crossbeam in middle sieve plate 5 and lower sieve plate 6 and screen box, be provided with the rubber slab of 6mm, described damping spring 1 is installed in frame 9, described vibrating motor 7 is bolted and is arranged on screen box 8, between screen box 8 and coal spout, be connected with screw with nylon canvas.
On request shock-damping structure is contained on support, screen(ing) machine is hung up with steel wire rope 3 and rope clamp, then adjust wire tensioner 2, make screen(ing) machine entrance level, four shock-absorbing springs 1 stressed evenly (can measure by the height of four spring-compresseds).If highly basically identical, stressed consistent.The compressed height of spring of former and later two shock absorbers has allowed error to exist, but in two groups of front and back, every group of two springs must be adjusted to highly consistent.Need when changing when spring damages, require whole group of spring simultaneously with changing, in the time of zero load the amplitude of screen(ing) machine be adjusted at 4～5mm or according to ature of coal situation suitably strengthen or amplitude contraction (as sticky in ature of coal or treating capacity is large, adopt large amplitude, be generally no more than 6mm; If ature of coal is compared with loose or treating capacity is little, adopt little amplitude work), can improve like this service life of machine, and reduce noise.The method of adjusting amplitude is the bias coincidence angle that changes motor two ends, but must make four groups of eccentric block coincidence angles on two motors consistent, otherwise can cause swing.The necessary locking nut of eccentric block of adjusting, in the end adjusts on required amplitude, then floor clip is locked.The large I of amplitude is directly observed the graduation mark on amplitude board, and the indicated numeral of abscissa of two line intersection points is the amplitude of adjustment.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
