Abstract
The utility model discloses an anti-blocking device used in a cantilever screen, which comprises a vibrating frame and more than one striking bar. The vibrating frame includes a fixed beam for installing screen bars and more than two installing plates, the fixed beam is fixed on the installing plate, two ends of each of the more than one striking bar are respectively installed on two adjacent installing plates, and the more than one striking bar is arranged below the screen bars. The device has the advantages of simple and compact structure, low cost, long service life, convenient maintenance and wide application range.
Description
Technical field
The utility model is mainly concerned with the vibratory sieve field, refers in particular to a kind of mechanism that is used to prevent the Suspension arm sieve obstruction.
Background technology
The screen cloth of Suspension arm sieve generally adopts grating to make, and it is installed for cantilever, can produce secondary vibration, and with the screen cloth ratio of other form, the phenomenon that material is sandwiched between grating reduces, but still exists.So it is necessary with preventing clogging up device that Suspension arm sieve is set.
At present, Suspension arm sieve is more with the preventing clogging up device scheme, but has dropped into the few of application.Wherein a kind of mode is to be provided with in the bottom surface of grating middle and lower part to hit pipe, and this strike pipe is fixed in by mandrel on the side plate at two ends, hits pipe box and is located on the mandrel.Utilize the strike pipe that the material that is clipped between grating is removed in the impact of grating bottom.The shortcoming of this device is: because compass screen surface is very long, therefore the distance between two blocks of side plates is also longer, can only be designed to slender axles and be fixed in two mandrels on the side plate, and it is not too convenient that it installs the location, and in use be easy to generate distortion.In case the mandrel distortion, the gap of hitting between pipe and the mandrel will diminish, hit pipe and will diminish, even lose the impulsive force bottom the grating, and anti-clogging function variation, this structure is often not long service life.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provides a kind of simple and compact for structure, with low cost, long service life, Suspension arm sieve preventing clogging up device easy to maintenance, applied widely.
For solving the problems of the technologies described above, the utility model by the following technical solutions.
A kind of Suspension arm sieve preventing clogging up device, it is characterized in that: involving vibrations framework and the striking bar more than, described vibration frame comprises built-in beam and the installing plate more than two that is used for installing grating, described built-in beam is fixed on the installing plate, the two ends of described every striking bar are installed on respectively on adjacent two installing plates, and described striking bar is positioned at the grating below.
As further improvement of the utility model:
Offer the striking bar installing hole on the described installing plate, the two ends of described striking bar are sheathed on respectively in the described striking bar installing hole, leave the vibration gap between the inwall of described striking bar and striking bar installing hole.
Described striking bar is the axle shape spare that the centre is thick, two ends are thin, or has the axle shape spare of same diameter.
Compared with prior art, advantage of the present utility model just is: Suspension arm sieve preventing clogging up device of the present utility model, have simple and compact for structure, with low cost, long service life, advantage such as easy to maintenance, applied widely, during assembling, only need many striking bar are installed in interior the getting final product of striking bar installing hole of installing plate, very easy; Utilize beating of striking bar just can remove the material that is clipped between grating, but in all extensive uses of industries such as coal, mine, metallurgy.

The specific embodiment
Below with reference to specific embodiment and Figure of description the utility model is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, Suspension arm sieve preventing clogging up device of the present utility model, involving vibrations framework 6 and the striking bar more than one 4, vibration frame 6 comprises built-in beam 2 and the installing plate more than two 1 that is used for installing grating 3, built-in beam 2 is fixed on the installing plate 1, the two ends of every striking bar 4 are installed on respectively on adjacent two installing plates 1, and striking bar 4 is positioned at grating 3 belows.Installing plate 1 comprises that built-in beam 2 passes and is fixed on side plate 8 and the middle support plate 5 at the side plate 8 at two ends and at the middle support plate 5 more than between the side plate 8.In the present embodiment, offer striking bar installing hole 7 on the installing plate 1, this striking bar installing hole 7 can be blind hole or through hole, and the two ends of striking bar 4 are sheathed on respectively in the striking bar installing hole 7, leaves the vibration gap between the inwall of striking bar 4 and striking bar installing hole 7.The axle shape spare thick in the middle of striking bar 4 can adopt, that two ends are thin, or adopt axle shape spare with same diameter.Two ends are littler than the diameter of bore of striking bar installing hole 7 with the diameter of striking bar installing hole 7 junctions on the striking bar 4, and grating 3 bottom surfaces are less than on the striking bar 4 the two ends outer surface to the distance between striking bar installing hole 7 inwalls to the distance of striking bar 4 upper surfaces.During work, when the cantilever screen frame vibrates, drive vibration frame 6 vibrations, 4 of striking bar can produce thereupon beats, and beating of striking bar 4 will impact the bottom surface of grating 3, thereby can clear up the material that 3 quilts of grating press from both sides, thereby reach the anti-clogging purpose.
Below only be preferred implementation of the present utility model, protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the utility model principle prerequisite, for example, built-in beam 2 also is designed to segmentation structure, every section all between adjacent installing plate 1; Perhaps, be provided with in addition on the striking bar 4 and be used for cleaning piece of clearing up 3 putties of adjacent grating or the like, these improvements and modifications also should be considered as protection domain of the present utility model.
