Specific embodiment
The illustrative embodiments of the utility model are described in detail with reference to the accompanying drawings.To illustrative embodiments
Description merely for the sake of demonstration purpose, and be definitely not limitation to the utility model and its application or usage.
Fig. 1 is the schematic diagram for showing the damping device according to the present utility model for vibrating screen, is subtracted wherein illustrating
Shake device is connected to the situation on vibrating screen.
As shown in fig. 1, the damping device according to the present utility model for vibrating screen includes: rubber shock-absorbing spring 1, determines
Position column 2, fastener 3, spacer 4 and positioning pin 5.Wherein, one end of positioning column 2 can be movably attached to by positioning pin 5 and is used for
On the frame 8 for installing vibrating screen.Frame 8 is usually the frame of steel construction, and thus installing vibrating screen can comparatively robust.As one kind
Embodiment, is provided with hole on usual frame 8, and one end of positioning column 2 can pass through the hole on frame 8, and by positioning pin 5 into
Row limit, as shown in the figures.However, it will be understood that positioning column 2 can also pass through it in addition to above-mentioned connection type
His mode is connected on frame 8, if convenient for limit and it is easy to disassemble.
One end of rubber shock-absorbing spring 1 is fixedly attached to spacer 4, and the other end of rubber shock-absorbing spring 1 is nested in positioning column 2
On.Spacer 4 is equipped with internal screw thread.For example, by the screw-internal thread fit of fastener 3 and spacer 4 for bolt, rubber can be subtracted
One end of shake spring 1 is fixedly attached to vibrating screen.Preferably, damping device according to the present utility model further includes vibrating screen support
Seat 7, as shown in the figures.In this case, one end of rubber shock-absorbing spring 1 is fixedly attached to by spacer 4 and fastener 3
Vibrating screen support base 7.Vibrating screen support base 7 is for being fixedly attached to vibrating screen.
In addition, the quantity of rubber shock-absorbing spring 1 is not limited to one, it can be multiple rubber shock-absorbing springs with multi-point support
Mode is arranged, and the quantity of specifically used rubber shock-absorbing spring 1 can be matched according to the weight of vibrating screen, to reach most
Good damping effect.As an example, such as in the case where vibrating screen is smaller relatively light, settable 4 rubber shock-absorbing springs 1 are divided into 4
A point support.And in the larger heavier situation of vibrating screen, the vibrating screen of e.g., about 800kg weight, settable 8 rubber shock-absorbings
Spring 1,8 springs can divide four groups, and every group two, at a supporting point, thus to reach best damping effect.
The application example of an embodiment according to the present utility model, one end of rubber shock-absorbing spring 1 for example, by for
The fastener 3 and spacer 4 of bolt are fixedly attached to vibrating screen support base 7, to be fixedly attached to vibration by vibrating screen support base 7
On dynamic sieve side wall 2, as shown in Figure 1.One end of the rubber shock-absorbing spring 1 of damping device is fixedly attached to vibrating screen as a result,
On, that is, rubber shock-absorbing spring 1 is fixedly attached to vibrating screen side wall 2 by spacer 4 and fastener 3 and vibrating screen support base 7,
The rigid connection with vibrating screen is realized, to guarantee damping effect.And the other end and frame of the rubber shock-absorbing spring 1 of damping device
8 are flexibly connected, that is, the other end of rubber shock-absorbing spring 1 is movably attached to for example, steel construction by positioning column 2 and positioning pin 5
Frame 8, to reduce vibrating screen to the exciting force of frame 8.
As described above, in the application, it is another that one end of damping device according to the present utility model is rigidly connected to vibrating screen
End is movably attached to frame.It, can be by the way that fastener 3 be unloaded, for example, by bolt 3 when needing replacing rubber shock-absorbing spring 1
It backs out, extracts positioning pin 5 out, move down positioning column 2, vibrating screen is lifted to the deflection of rubber shock-absorbing spring later, i.e.,
Rubber shock-absorbing spring can be replaced.As an example, as described above, when be applied to about 800kg weight vibrating screen when, herein
In situation, the spring deflection of rubber shock-absorbing spring is between 2-5mm.Thus only need to raise vibrating screen 2-5mm, Ji Kegeng
Rubber shock-absorbing spring is changed, so that it is simple, convenient more to change jobs, it is time saving and energy saving.
In the present invention, common metal spring is replaced using rubber shock-absorbing spring, is existed to avoid metal spring
Horizontal distortion generates large effect in the course of work.
Damping device according to the present utility model for vibrating screen is capable of fixing due to one end of rubber shock-absorbing spring
Vibrating screen with vibrating screen to be rigidly connected, and the other end is directly sleeved on positioning column, can be movably attached to frame by positioning column
Frame reduces the vibration of vibrating screen caused by frame so greatly reducing the exciting force of the frame to for example, steel construction
Injury tolerance.Simultaneously as the structure of positioning column and positioning pin has been used, but also replacement spring is very convenient in use, only
Vibrating screen need to be raised to several millimeters can be completed replacement, and it is time saving and energy saving to have achieved the effect that.
Although the utility model is described referring to illustrative embodiments, but it is to be understood that the utility model
It is not limited to the specific embodiment be described in detail and shown in text, in the feelings without departing from claims limited range
Under condition, those skilled in the art can make various changes to the illustrative embodiments.These changes should all fall into this reality
With novel protection scope.
