Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail, as shown in the figure: vibratory sieve of the present invention, comprise screen box, be positioned at the screen cloth 3 of screen box inside, traverse screen box and the main shaft be rotatably assorted with screen box, be arranged on main shaft with the vibrator 1 that main shaft rotates, the shaft coupling 2 be connected successively with main shaft and motor, described vibrator is two disk 1a, disk be provided be placed on main shaft and with through hole 1b and at least two of disk decentraction with disc centre apart from different aperture 1c, by connecting apart from equal aperture bolt 1d with disc centre between two disks, when needing adjustment vibratory sieve amplitude, two disks are connected by different apertures.
As the further improvement of technique scheme, described vibrator is two, lays respectively at main shaft two ends, and vibration is more even, can effectively prevent the phenomenons such as main shaft eccentric wear from producing, the service life of extension device.
As the further improvement of technique scheme, the elastomer 2a that described shaft coupling comprises two half a couplers and is connected to for transmitting torque between two half a couplers, described half a coupler comprises axle sleeve 2b and pressure ring 2c, axle sleeve one end is provided with flange, and elastomeric two ends to be pressed on respective bushing collars and to be connected by bolt 2d by the pressure ring of two half a couplers respectively.Elastomer can compensate the axial displacement between two-semiaxle, and meanwhile, also make to be formed between motor and the main shaft of vibration to be flexible coupling, when avoiding vibratory sieve to work, motor suffers damage.
As the further improvement of technique scheme, described elastomer is bent into arc top along the radially outer arc of main shaft by Rectangular Elastic sheet, and described elastomer is two or more, and is along the circumferential direction uniformly distributed, axial displacement compensation effect is better, and transferable moment of torsion increases greatly.
As the further improvement of technique scheme, described screen cloth is double layer of metal structure, and bottom screen 3a is fixed on screen box, and upper strata screen cloth 3b to be arranged on bottom screen and detachable, upper strata sieve number is greater than bottom screen order number, according to the upper strata screen cloth of the replaceable different meshes of difference screening thing.
