Description
Technical field
The utility model relates to a kind of vibratory sieve, relates in particular to the automatically controlled three-axis elliptic sieve of a kind of gearless.
Background technology
Three-axis elliptic sieve is indispensable material grading apparatus in all industries such as metallurgy, coal, mine, and three shaft elliptic vibrative screen can carry out classification to material, have that efficiency is high simultaneously, amplitude greatly, 0-5 ° mounted angle, the plurality of advantages such as easy for installation.Along with the development of mobile screening station, the little advantage of large amplitude, high efficiency, mounted angle of three-axis elliptic sieve just becomes the supporting preferred unit of mobile screening station; Traditional three-axis elliptic sieve is all that employing is gear-driven, change the movement locus of material on screening machine by the phase angle of balancing weight on gear synchronous device adjusting gear, but gear is difficult to install, dismounting inconvenience, adopt the easy leakage of oil of thin oil lubricant, and gear cover easily causes screening machine beat; Because of the present circumstance, need to adopt a kind of three-axis elliptic sieve of new technique to replace traditional gear drive three-axis elliptic sieve.
Summary of the invention
The difficulty of bringing in order to overcome the gear drive of traditional three-axis elliptic sieve, the utility model adopted the vibrator of electronic control technology control three-axis elliptic sieve, replaced gear synchronous device and change by balancing weight phase angle on adjusting gear the technology of Material moving track.Electronic control technology can be by the motion state of three vibrators of electrical control cubicles control, does not have gear synchronous device can realize elliptic motion, realizes each vibrator keep determining phase place with electrical control means.
The utility model is in order to solve its technical problem, by the following technical solutions: the automatically controlled three-axis elliptic of described gearless sieves mainly by electrical control cubicles, variable-frequency motor, vibrator, the parts such as screen box form, electrical control cubicles control variable-frequency motor, variable-frequency motor drives vibrator, vibrator is arranged on screen box, and vibrator motion produces exciting force and drives screen box vibration, and then makes screen box have grading.
Described vibrator comprises main shaft, main shaft is arranged on bearing block, bearing block adopts high-strength bolt pair and bearing block platen to fix, main shaft two ends are respectively by shaft coupling universal-joint, the two ends of described main shaft are respectively equipped with eccentric block, main shaft adopts labyrinth ring connection bearing gland outward, and some self-aligning roller bearings are set between bearing gland and main shaft, and described vibrator is provided with outer cover and middle short cover.
Phase place and the rotating speed of electrical control cubicles major control variable-frequency motor; Variable-frequency motor drives vibrator; The motion state of vibrator has determined the movement locus of screen box, and vibrator does not need the control of gear synchronous device, simple in structure, easy accessibility;
The beneficial effects of the utility model are that, by adopting the motor synchronizing control technology control three-axis elliptic sieve of variable-frequency motor, drive system structure is simple; The day-to-day works such as lubricated, the maintenance of machine and maintenance are greatly simplified; While having reduced startup, parking, cross the resonance amplitude of the vertical and horizontal direction of resonance region; Under high-power, be convenient to adopt many motors not increase exciting force and improve force-bearing situation; Technical know-how maturation, can ask synchronism criterion and stability dish square to vibrate resistance moments method and Hamiton's principle, can determine the screen(ing) machine motion state of synchronous vibration according to vibration mechanics.

Detailed description of the invention
The automatically controlled three-axis elliptic sieve of gearless figure as shown in Figure 2, formed by electrical control cubicles (4), variable-frequency motor (3), vibrator (2) and screen box (1), electrical control cubicles (4) is controlled variable-frequency motor (3), variable-frequency motor drives vibrator (2), 3 groups of vibrators (2) are arranged on screen box (1), vibrator (2) motion produces exciting force and drives screen box (1) vibration
As shown in Figure 4, described vibrator (2) comprises main shaft (8), main shaft (8) is arranged on bearing block (14), bearing block (14) adopts high-strength bolt pair (10) and bearing block platen (13) to be fixed on together on screen box (1), main shaft (8) two ends connect two ends universal joints (5) by shaft coupling (6) respectively, the two ends of described main shaft (8) are respectively equipped with eccentric block (15), balancing weight (16) is housed on eccentric block (15), for adjusting amplitude, bearing block (14) two ends adopt labyrinth sealing mode, labyrinth ring (9) connection bearing gland (11) forms labyrinth structure, 2 dish import self-aligning roller bearings (12) are set between bearing gland (11) and main shaft (8), outer cover (7) and middle short cover (17) protection for described vibrator (2).
When use, universal joint (5) drives vibrator main shaft (8) transmission, and the eccentric block (15) on main shaft produces exciting force and drives whole screen box (1) vibration, and then makes screen box (1) have sieving actoion.Adopt motor synchronizing control technology, by electrical control cubicles (4) control 3 variable-frequency motors (3) thus phase place and rotating speed regulate the duty of 3 groups of vibrators (2) to make three-axis elliptic sieve realize elliptic motion.Synchronism criterion and stability dish square can be asked with vibration resistance moments method and Hamiton's principle, the screen(ing) machine motion state of synchronous vibration can be determined according to vibration mechanics.
The outstanding feature of the utility model is to have taken leave of traditional gear-driving three-axis elliptic sieve, and when design, the position of three vibrators can at will regulate, and has broken away from travelling gear driven three-axis oval screen and has relied on gear-driven limitation and drawback.This three-axis elliptic sieve technology content significantly improves, and simple in structure, output also increases thereupon, and market prospects are unlimited, are also the preferred units of following mobile screening station.
