Description
Technical field
The utility model relates to mine screening plant fields, and in particular to a kind of vibrating screen.
Background technique
Screening plant is important equipment necessary to the industrial departments such as mine, ore dressing, coal separation, building materials, steam power plant, chemical industry,
It is mainly used for conveying, classification, dehydration, the drying etc. of material, is mainly made of components such as screen box, vibrator, elastic elements.
The vibrator of vibrating screen includes the eccentric parts such as eccentric block or eccentric shaft, drives the rotation of vibrator eccentric shaft by motor
Turn, to generate centrifugal force, this centrifugal force is acted on screen box, so that screen box generation be driven circumferentially to vibrate.Screen box is provided with
The sieve of several layers of different pore size, by vibration, the material less than screen mesh size falls into sieve lower layer, greater than the material of screen mesh size
Sieve upper layer is stayed in, to achieve the purpose that material size is classified.
The structure of existing vibrating screen is as shown in fig. 1, and motor is rotated by driving belt driving belt pulley 1, and belt pulley 1 is solid
Surely it is connected with belt pulley tapered sleeve 2, belt pulley tapered sleeve 2 is equipped with axis hole 3, and eccentric shaft 4, the driving sieve of eccentric shaft 4 are equipped in axis hole 3
Case 5 vibrates, since the center of the axis hole 3 at the center and belt pulley tapered sleeve 2 of belt pulley 1 is arranged concentrically, when screen box 5 vibrates, and belt
Wheel 1 and 5 synchronous vibration of screen box, and then cause driving belt to stretch, shrink repeatedly, be easy to appear loud noise and jump zoning,
Also result in that driving belt fever is serious, aging quickening, the lost of life.
Utility model content
Belt pulley caused by can reducing the technical problem to be solved by the utility model is to provide one kind because of screen box vibration
The vibrating screen of synchronous vibration.
To achieve the above object, the technical solution that the utility model is taken are as follows: a kind of vibrating screen, including motor, pulley,
Eccentric shaft and screen box, motor are rotated by driving belt driving belt pulley, and belt pulley is fixedly connected with belt pulley tapered sleeve, belt pulley
Tapered sleeve is equipped with axis hole, and eccentric shaft is equipped in axis hole, and eccentric shaft drives screen box vibration, the center of belt pulley and belt pulley tapered sleeve
Axis hole center eccentric setting.
The center of belt pulley is consistent with the amplitude of screen box with the eccentricity at the center of the axis hole of belt pulley tapered sleeve.
The vibrating screen of the utility model, including motor, pulley, eccentric shaft and screen box, motor are driven by driving belt
Pulley rotation, belt pulley are fixedly connected with belt pulley tapered sleeve, and belt pulley tapered sleeve is equipped with axis hole, is equipped with bias in axis hole
Axis, eccentric shaft drive screen box vibration, the center eccentric setting of the axis hole at the center and belt pulley tapered sleeve of belt pulley, to effectively subtract
The synchronous vibration of belt pulley when small screen box vibrates, and then the problems such as avoid the stretching repeatedly and noise aging of driving belt.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art of the utility model；
Fig. 2 is the structural schematic diagram of specific embodiment of the utility model one.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
The specific embodiment one of the vibrating screen of the utility model, as shown in Figure 2, including motor, pulley, eccentric shaft and
Screen box, motor are rotated by driving belt driving belt pulley 1, and belt pulley 1 is fixedly connected with belt pulley tapered sleeve 2, belt pulley tapered sleeve 2
It is equipped with axis hole 3, eccentric shaft is installed in axis hole 3, eccentric shaft drives screen box vibration, the center line 11 and belt pulley of belt pulley 1
31 eccentric setting of center line of the axis hole 3 of tapered sleeve 2, then the synchronous vibration of belt pulley 1 when can reduce screen box vibration, and then avoid passing
The problems such as stretching repeatedly and noise aging of dynamic belt.
Preferably, the amplitude one of the eccentricity d and screen box at the center of the axis hole 3 of the center of belt pulley 1 and belt pulley tapered sleeve 2
It causes, thus the vibration of belt pulley 1 caused by sufficiently avoiding screen box from vibrating.
Finally, it is stated that: above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field
Other modifications or equivalent replacement that those of ordinary skill makes the technical solution of the utility model, it is practical without departing from this
The spirit and scope of new technique scheme should all cover in the scope of the claims of the utility model.
Claims (2)
1. a kind of vibrating screen, including motor, pulley, eccentric shaft and screen box, motor are rotated by driving belt driving belt pulley,
