Abstract
The invention provides two technical schemes of a beating sleeve for a cantilever screen. In the first scheme, the beating sleeve comprises a cylindrical barrel-shaped beating sleeve body, a spiral projected table is arranged on the outer surface of the beating sleeve body, or a fixed spiral spring is arranged on the outer surface of the beating sleeve body. In the second scheme, the beating sleeve body of the beating sleeve is a cylindrical spiral body. Through the two structures, the outer surface of the beating sleeve is changed into the unsmooth cylindrical surface with height variations, and the stress of two adjacent screen strips can be different when the cylindrical surface beats on the screen strips, so the two screen strips have different vibration and unequal amplitudes, materials blocked between the two screen strips are favorably removed, and the blocking prevention effect is improved.
Description
Technical field:
What the present invention relates to is the part in a kind of industrial screening plant, and especially a kind of Cantilevered screen is with hitting cover
Background technology:
In the prior art, technique known is the strike cover in usefulness, at present; The used strike cover of Cantilevered screen all is that cylinder is barrel-shaped, and its outer surface also all is the smooth face of cylinder, and such face of cylinder is when hitting grating; The suffered impulsive force of each grating is more or less the same, and therefore, the vibration of each grating does not have very big difference yet; This is just unfavorable to the tamper of removing between two gratings, can not reach best anti-clogging effect, and this is the existing in prior technology weak point.
Summary of the invention:
The present invention is exactly not enough to existing in prior technology; And providing a kind of Cantilevered screen with hitting the cover technical scheme, this scheme is employed in to hit and increases spiral protrusion or helical spring on the smooth outer surface of cover, makes the outer surface that hits cover become the rough face of cylinder that exists height to change; Hit on grating on such face of cylinder; The stressed of adjacent two gratings do not waited, so the vibration of two gratings is different, amplitude does not wait; Help rejecting the material that is blocked between two gratings, improved the anti-clogging effect.
This programme is realized through following two technical measures:
First technical scheme: include the barrel-shaped strike body of cylinder, the characteristics of this programme are that the outer surface at described strike body has the spiral convex, or at the outer surface that hits body fixing helical spring are arranged.The concrete characteristics of this programme also have, and described spiral convex height is the 3-10 millimeter.Described helical spring diameter is the 3-10 millimeter.Described spiral convex and helical spring pitch are the 10-30 millimeter.Described helical spring diameter is preferably 6 millimeters.
Second technical scheme: include the strike body, the characteristics of this programme are that described strike body is columniform conveyor screw.
The beneficial effect of this programme can because the outer surface at the strike body has the spiral convex in this scheme, or have fixing helical spring at the outer surface that hits body according to the narration of above-mentioned two schemes is learnt; Perhaps hitting body is exactly columniform conveyor screw.This structure; Make the outer surface that hits body become the rough face of cylinder or the columniform conveyor screw that exists height to change, this rough face of cylinder or conveyor screw hit on grating, just can make the stressed difference of adjacent two gratings; The vibration that therefore adjacent two gratings produce is different; Amplitude does not wait, so help rejecting the material that is blocked between two gratings, has just improved the anti-clogging effect yet.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure sketch map of first technical scheme specific embodiment of the present invention.
Fig. 2 is the left TV structure sketch map of Fig. 1.
Fig. 3 is the part sectional structure sketch map of second technical scheme specific embodiment of the present invention.
1 for hitting body among the figure, and 2 is helical spring.
The specific embodiment:
For clearly demonstrating the technical characterstic of two schemes, below respectively through a specific embodiment, and combine its accompanying drawing, two schemes are set forth.
First technical scheme:
Can find out that through attaching Fig. 1 and 2 the Cantilevered screen of this programme has the barrel-shaped strike body 1 of cylinder with hitting cover, this programme is that the outer surface at described strike body 1 has the spiral convex, and described spiral convex height is the 3-10 millimeter, and pitch is the 10-30 millimeter.Also can fixing helical spring 2 be arranged at the outer surface that hits body 1, described helical spring 2 diameters are the 3-10 millimeter, are preferably 6 millimeters, and pitch is the 10-30 millimeter.What this concrete substantive examination mode adopted is at the outer surface that hits body 1 fixing helical spring 2 to be arranged, and described helical spring 2 diameters are 6 millimeters, and pitch is 18 millimeters.
Second technical scheme:
Can find out that through accompanying drawing 3 Cantilevered screen of this programme is with hitting cover, the strike body 1 of this strike cover is exactly a columniform conveyor screw.Constituting spirochetal material cross-section can be arbitrary plane shape, and what this specific embodiment adopted is rectangle.
Claims (6)
