The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is explained.

Referring to Fig. 1, a kind of Novel single banana screen of the present invention, main lateral wall 1, vibrator 2, jackshaft 3, driving shaft 4, motor 5, belt gear 6, countershaft pair 7, buffer spring 8, sieve plate 9, excitation beam of vibration 10, crossbeam 11, spring support 12, draw-beam 13, rail chair angle steel 14, postnotum 15 form.

The inclination angle on lateral wall 1 nethermost limit from feeding end to discharge end the angle of (Fig. 1 from right to left) successively decrease successively, be respectively 25 °, 20 °, 15 °, 10 °, 5 °.Lateral wall 1 not only can prevent that coal from leaking down from side, departs from compass screen surface; And the structure such as mounted sieve 9, crossbeam 11, the thereon structure such as mounting spring support 12 betwixt.

The two ends of draw-beam 13 are fixedly connected with lateral wall 1.Crossbeam 11 is arranged on the below of sieve plate 9 and is fixedly connected with sieve plate 9 by rail chair angle steel 14.Crossbeam 11 is installed and can be made sieve plate 9 more firm, make sieve plate 9 along with screen(ing) machine together vibrates and makes compass screen surface vibration frequency everywhere consistent.The two ends of crossbeam 11 are fixedly connected with lateral wall 1.Postnotum 15 is positioned at lateral wall 1 low order end.Excitation beam of vibration 10 two ends are fixedly connected with lateral wall 1.

The sieve nest of lateral wall 1, crossbeam 11, excitation beam of vibration 10, draw-beam 13 and postnotum 15 these practical mono-layer banana screens of main composition.Lateral wall 1, crossbeam 11, draw-beam 13 and postnotum 15 all select the riveted joint of high-quality HUCK steel fixing.Crossbeam 11 and the draw-beam whole heat treatment of 13 postwelding are also carried out carrying out flaw detection, use senior Digit Control Machine Tool to carry out machined, then select ring-grooved rivet, adopt clean sealing assembly technology that sieve nest riveted joint is fixing.Lateral wall 1 no-welding-seam; Crossbeam 11, excitation beam of vibration 10 section factors are large, rigidity is large.After reaching Sa2.5 level, lateral wall 1, draw-beam 13, excitation beam of vibration 10, postnotum 15 and crossbeam 11 surface treatments spray polyester protective paint.Because sieve nest structure is by optimal design, lightweight; Under high load capacity high-frequency vibration duty, can effectively avoid splitting and wearing and tearing of each parts, there is higher anti-fatigue ability and reliability; Long service life.

Two vibrators 2 are arranged on excitation beam of vibration 10 both sides, and are connected by jackshaft 3.Vibrator 2 comprises the parts such as centering block, axle, gear, plug cock.

The two ends of jackshaft 3 connect respectively vibrator 2, make the vibrator 2 can synchronous rotary.The two ends of jackshaft 3 adopt unique elastic caoutchouc dish shaft coupling to be connected with the centering block of vibrator 2.

Driving shaft 4 is connected with vibrator 2, is universal drive shaft.

Motor 5 staring torques are large, accelerate soon, can make screen(ing) machine spend rapidly resonance region.Motor 5 is arranged on track base.Motor 5 is connected with belt gear 6.Belt gear 6 adopts SPB belt transmission to carry out speed governing deceleration, and transferring power, adjusts belt tightening with track base leading screw degree of tightness motor 5.

Countershaft pair 7 is comprised of countershaft, SKF bearing, sleeve, labyrinth seal box open bearing seat, convenient for installation and maintenance.

Spring support 12 is arranged on respectively the both sides of feeding end lateral wall 1 below and the both sides of discharge end lateral wall 1 below.Spring support 12 is connected with buffer spring 8.The other end of buffer spring 8 is fixedly connected with screen(ing) machine base support.The two ends of buffer spring 8 are provided with rubber blanket, to reduce wearing and tearing and the noise of spring 8 and seat board.The rigidity of buffer spring 8 is little, and damping efficiency can reach more than 98%.

Sieve plate 9 surface design are 5 sections of fold-line-shapeds of 5 angle, inclination angle from feeding end to discharge end the angle of (Fig. 1 from right to left) successively decrease successively, be respectively 25 °, 20 °, 15 °, 10 °, 5 °.The object of design is like this: feeding end feed is many, but the inclination angle of sieve plate 9 is large, and material movement speed is accelerated, and the rapid attenuation of the bed of material also separates very soon, makes easily saturating sieve of material; Middle each section and discharge end compass screen surface are processed piecemeal front end and have thoroughly been sieved part material afterwards, and material reduces gradually.

Operation principle: motor 5 energising operations, by belt gear 6, carry out speed governing, by countershaft pair 7, driving force is passed to driving shaft 4 and drive vibrator 2 runnings to produce straight-line oscillation power, straight-line oscillation power moves in circles continuous action on sieve nest, sieve nest is vibrated on buffer spring 8, simultaneous buffering spring 8 can reduce the load of sieve nest to screen(ing) machine base support, sieve nest drives sieve plate 9 synchronous vibrations, sieve plate 9 passes to sieve plate 9 material above by power, material is thrown on sieve plate 9 advance the compacting layering saturating sieve classification of dynamics in accordance with regulations, make material successively from feeding end, move to discharge end, compass screen surface by sieve plate 9 sieves processing, the material that sees through sieve aperture falls into material collecting tank, the material of discharging from discharge end falls in discharge groove.

Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
