Detailed description of the invention
The spin vibration sieve embodiment novel to the utility model referring to figs. 1 through Fig. 2 is described further.
As shown in Fig. 1 to 2, a kind of novel spin vibration sieve, comprises motor housing 2 and vibratory sieve 1, is provided with spring 5 between motor housing 2 and vibratory sieve 1, and the axial two ends of spring 5 are connected on motor housing 2 and vibratory sieve 1.What this spring 5 adopted is cylindroid helical-coil compression spring, and axially the two ends of corresponding motor housing 2 and vibratory sieve 1 polish respectively.
Spring acting as in spin vibration sieve: the vibration realizing vibratory sieve, reduces ground vibration, and can reduce noise.In the rotary screen that this is novel, be provided with support bar between motor housing 2 and vibratory sieve 1, spring 5 is set on support bar.Support bar comprises two parts: the first support bar 3 and the second support bar 4, first support bar 3 and the second support bar 4 adopt and to be sheathedly slidably connected.First support bar 3 and the second support bar 4 are hollow cylindrical, the diameter of the first support bar 3 is greater than the diameter of Second bobbin diameter bar, further, in the first support bar 3, the diameter of cylindrical cavity is slightly larger than the second support bar 4 diameter, and the second support bar 4 can assign in the interior cylindrical cavity of the first support bar 3.In first support bar 3, corresponding second support bar 4 place of cylindrical cavity is provided with spacing collar, corresponding first support bar 3 place of second support bar 4 outer surface is provided with the limited block coordinated with spacing collar, the while that first support bar 3 and the second support bar 4 realizing telescopic in the axial direction, limited block and spacing collar can at a time be conflicted mutually, avoid the first support bar 3 to be separated with the second support bar 4.
As a kind of embodiment of the present utility model, the first support bar 3 is by being articulated and connected on vibratory sieve 1, and the holder 6 of the second support bar 4 by arranging at corresponding second support bar 4 of motor housing 2, realizes the hinged of the second support bar 4 and motor housing 2.Holder 6 comprises corresponding two fixed arms arranged, and two fixed arms are rotatably provided with rotating shaft, and the end of the second support bar 4 is connected in rotating shaft.The connected mode of support bar and motor housing 2 adopts hinged form, when producing the vibration of horizontal direction, support bar is along with change direction, horizontal-shift direction, spring 5 and support bar is made to remain original form, spring 5 can not contact support bar, support bar can not impact spring 5, makes vibration stable, steady.
Arranging of support bar can protect spring 5, strengthens the fatigue resistance of spring 5, extends the service life of spring 5.Support bar adopts telescopic mode, when this novel spin vibration sieve works, vibratory sieve 1 produces vibration, spring 5 stretches, and to slow down the vibration to motor housing 2, and the flexible of spring 5 is also the vibrative necessary condition of vibratory sieve 1, support bar can stretch along with the flexible of spring 5 in the vertical direction, and can not conflict motor housing 2 and vibratory sieve 1, make it not affect the amplitude of vibration, do not affect the operating efficiency of equipment.
Vibratory sieve 1 will inevitably produce skew in the horizontal direction while vibration, and spring 5 can produce bending along with the skew of vibratory sieve 1.And the second support bar 4 adopts hinged mode to be exactly Bending Deformation in order to not affect spring 5.Support bar can bending along with spring 5, and turn, when avoiding spring 5 to bend and need vibrate in the axial direction, conflict support bar, affects the duty of spring 5.Make spring 5 carry out work without impact is regular, vibration frequency is stablized, and can make the spin vibration sieve working stability that this is novel, improves the production efficiency of equipment.
The above is only preferred embodiment of the present utility model; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and change, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
