Also illustrating the installation site of flexible screen 11 on floating screen frame 5 in Fig. 3, for better understanding the technical program, referring to Fig. 5.Floating crossbeam 5 and fixed cross beam 4 are all provided with buckle 22.Buckle 22 forms for section bar channel-section steel is bending, and buckle 22 comprises two side and formation opening is tightened up to centre in this two side.All buckle 22(comprise the buckle on floating crossbeam 5 and the buckle on fixed cross beam 4) opening in the same plane.During use, buckle 22 opening that same flexible screen 11 both sides are arranged on floating crossbeam 5 is respectively interior with in buckle 22 opening of fixed cross beam 4; And in the opening of same buckle 22 all card have two flexible screens.
When adopting the technical scheme work of the present embodiment, motor drives exciting agency by Hooks coupling universal coupling, vibrating mechanism drives main screen frame to do class circular motion under the cooperation of rubber spring, main screen frame drives by shearing block rubber screen frame motion of floating when moving, can be out of shape owing to shearing block rubber, the screen frame that therefore floats is different from the class elliptic motion of main screen frame movement locus.Fixed installation flexible screen between then does the curve relaxation motion of track complexity.Screen surface is flexible, except the relaxation motion mode that conventional flip flop screen provides, makes in the middle part of screen cloth outside distortion, and in the technical program, screen cloth face can also omnibearing curvilinear motion, and screen cloth is also out of shape near the part of buckle 22.Therefore, the present invention can reach technique effect more better than prior art, effectively solves stifled sieve, sticks with paste the phenomenon of sieve.
During use, put into by charging aperture 10 higher from position for material to be sieved, under the vibration and Action of Gravity Field of flip flop screen, fall below screen cloth face after small particles material is sized, remaining material is then stopped from the comparatively downside of flip flop screen to go out to sieve by compass screen surface.
Only observe from superficial phenomenon, those skilled in the art it is generally acknowledged, the phenomenon that stifled sticking screen sieve occurs screen cloth is that screen cloth is hindered by large granular materials thus causes mesh to diminish, and the less material particles that then originally can pass through from mesh is being deposited in gap, thus occurs the phenomenon of stifled sticking screen sieve.
Inventor studies rear discovery, causes natively not susceptible to plugging straight line flip flop screen also to there will be the reason of blocking, the tension force of moisture film when being just that fine particle is united in gap.When comprising fine particle group and the flexible screen surface contact of moisture, cluster of grains and screen cloth face are linked by the tension force of water, when not adopting linear vibrating screen of the present invention to work, cluster of grains and screen cloth emaciated face are from the power perpendicular to screen cloth face mainly by producing during screen cloth relaxation, under water film surface tension force effect under this mode between cluster of grains and screen cloth face, granule group is difficult to be separated with screen cloth face, so, too much granule group piles up and not only makes the mesh of screen cloth diminish, more make not depart from screen surface difficulty (effect of moisture film tension force) by the large granular materials of mesh.Thus cause stifled sieve, stick with paste the phenomenon of sieve.
Technical scheme of the present invention is by the cooperation of rubber spring and class circumference polarization mode, main screen frame is made to do the motion of track complex curve, and the screen frame that floats does the more complicated curvilinear motion of track under the drive of main screen frame and the effect of inertia, the movement locus being arranged on the flexible screen between main screen frame and floating screen frame is then that short and small camber line forms more complicated curve (especially when there is the driving shaft/driven shaft of asynchronous rotation in exciting agency, above-mentioned track is more complicated).But be different from the flexible screen of traditional flip flop screen (with the part that the distance of floating crossbeam/fixed cross beam is nearer, then on screen cloth face, motional amplitude is also less), flexible screen in the technical program is at the move under influence of inertia and gravity, and whole screen cloth face can obtain balanced amount of exercise.In the above-described embodiments, main screen frame does class circular motion, and floating screen frame does class elliptic motion, and then ensures that the flexible screen be fixed on therebetween then does the curve relaxation motion of track complexity.When the straight line flip flop screen work of technical solution of the present invention, involved moisture fine particle group not is directly forced to depart from screen surface by the power perpendicular to screen surface after contacting with screen cloth face above, but this granule is rolled into a ball when not departing from screen cloth face along with class circular motion is done in screen cloth face, now, due to granule group movement locus and screen cloth face between and non-perpendicular, and, flexible screen surface has relaxation, therefore under the effect of inertia, granule group can along screen surface and generation relative sliding, so, granule group can not be bonded to the same point of screen surface.Granule group is then much easier than the stripping mode of prior art above from there being with it the screen surface of relative motion to peel off.In the present embodiment, granule group can skid off along the tangential direction of screen surface, departs from screen surface.Therefore, the straight line flip flop screen of technical solution of the present invention greatly alleviating the stifled sieve of existing straight line flip flop screen when sieving fine particle material, sticking with paste sieve phenomenon.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
