In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of special compass screen surface arrangement form that adopts, high-efficiency vibrating sieve in light weight, that screening efficiency is high, energy consumption is low and easy to maintenance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high-efficiency vibrating sieve, comprise screen box, screen box includes hopper, carriage and discharge bucket, by tensioning plate and pressing plate screen cloth is close to and is fixed on the carriage, be welded with the gusset in length and breadth of screen cloth typing location usefulness on the carriage, the vibrator that links to each other with screen box by bearing block is equipped with at the screen box middle part.
Described vibrator comprises eccentric shaft, sheath, big belt pulley, flywheel, eccentric block and bearing, and big belt pulley and flywheel adopt the swelling cover to be fixed on the eccentric shaft two axial ends of vibrator.
Big belt pulley links to each other with small belt pulley power on the motor by V belt.
Screen box is installed on the bearing of being made up of supporting base and support spring.
The damping unit that vibration damping is used is housed on the bearing.
The beneficial effects of the utility model are: adopt special compass screen surface arrangement form, sieve cloth is set to the horizontal single wave mode or the multimode of each cross section disparity curvature radius, material can diffuse to full compass screen surface after entering compass screen surface rapidly, material is difficult for causing the influence of lamination at compass screen surface, the finished product materials via hole rate of sifting out improves greatly, in addition overhanging place, screen box top device material bin, discharge bucket is equipped with at overhanging place, bottom, full compass screen surface is fully used, effective usable floor area of compass screen surface can reach to about 80～90%, its screening disposal ability is much larger than traditional heavy vibratory sieve, the conventional heavy-duty vibratory sieve identical with disposal ability compared: its compass screen surface work area only needs conventional heavy-duty vibratory sieve about 85%, complete machine weight alleviates 10% on year-on-year basis, can save equipment investment cost widely; Sieve same material output, its energy consumption lacks 1/5 than other type, thereby can reduce a large amount of production electricity costs; The high-efficiency vibrating sieve big belt pulley with change flywheel and being connected of eccentric shaft traditional keyway and are connected to swelling cover and connect, it connects quick, reliable, easy for assembly, disassembly and maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of carriage described in the utility model.
Among the figure: the 1-screen box, the 2-vibrator, the 3-big belt pulley, the 4-V belt, the 5-material bin, the 6-carriage, 7-is gusset in length and breadth, 8-screen cloth, 9-motor, 10-small belt pulley, 11-tensioning plate, 12-supporting base, 13-support spring, 14-damping unit, 15-discharge bucket.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1 to Fig. 4, a kind of high-efficiency vibrating sieve, comprise screen box 1, screen box 1 includes hopper 5, carriage 6 and discharge bucket 15, by tensioning plate 11 and pressing plate screen cloth 8 is close to and is fixed on the carriage 6, be welded with the gusset in length and breadth 7 of screen cloth 8 typing location usefulness on the carriage 6, the vibrator 2 that links to each other with screen box 1 by bearing block is equipped with at screen box 1 middle part, vibrator 2 comprises eccentric shaft, sheath, big belt pulley 3, flywheel, eccentric block and bearing, and big belt pulley 3 and flywheel adopt the swelling cover to be fixed on the eccentric shaft two axial ends of vibrator 2; Big belt pulley 3 links to each other with small belt pulley 10 power on the motor 9 by V belt 4; Screen box 1 is installed on the bearing of being made up of supporting base 12 and support spring 13; The damping unit 14 that vibration damping is used is housed on the bearing.
