Description
Technical field
The utility model relates to a kind of elliptically vibrating screen, for the screening of various ore deposits rock material.
Background technology
In prior art, vibrator adopts belt to be connected with motor conventionally, and belt is easily loosening after work certain hour, thereby often needs people for carrying out tensioning or replacing, has reduced production efficiency.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, can automatic tensioning belt elliptically vibrating screen.
The technical scheme in the invention for solving the above technical problem is: this elliptically vibrating screen, comprise screen box, base, vibrator and motor, described screen box is arranged on base, described vibrator is fixed on screen box, described vibrator is connected by belt with motor, it is characterized in that: also comprise belt stretcher, described belt stretcher is fixed on base, described belt stretcher comprises regulating wheel, connecting rod, telescopic spring base and tensioning spring, described connecting rod one end is hinged on base, the other end and regulating wheel are rotationally connected, described regulating wheel and belt are tangent and be pressed on belt, described spring base one end is fixed on base, the other end is connected with connecting rod, described spring base two ends are provided with and are equipped with limited block, described tensioning spring is enclosed within on spring base and between the limited block at spring base two ends, described spring has elastic potential energy.Regulating wheel withstands on belt, and promotes connecting rod by tensioning spring, and connecting rod rotates with its hinge, thereby regulating wheel is pressed on belt, thereby makes belt distortion carry out tensioning; After belt is loosening, tensioning spring, owing to there being elastic potential energy, will automatically regulate connecting rod, thereby regulating wheel will be regulated; Regulating wheel and connecting rod are for being rotationally connected, and when belt rotates, regulating wheel can follow belt to rotate, and its frictional force is less.
In the outer rim of regulating wheel described in the utility model, have the draw-in groove that prevents belt derailing, the shape of described draw-in groove and the cross sectional shape of belt match.Leather belt buckle, in draw-in groove, makes belt be difficult for skidding off and lost efficacy.
In vibrator described in the utility model, be provided with three rotating shafts, these three rotating shafts are equipped with pitch wheel, and the balancing weight of equal eccentric mass, identical eccentric arm is housed on each gear.During vibratory sieve work, motor drives three gear rotations of vibrator, and due to the setting of balancing weight, the movement locus of screen box is oval, and the vibration angle of screen box is adjustable.
Vibrator described in the utility model adopts gear-box type Xi oil lubrication system.Lubricant effect is better.
The utility model compared with prior art, has the following advantages and effect: simple in structure, reasonable in design, can to belt, regulate voluntarily, and prevent that belt from becoming flexible and losing efficacy.

The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 5, the elliptically vibrating screen in the present embodiment comprises screen box 1, base 2, vibrator 3, motor 4, belt 5, belt stretcher 6, damping spring 7 and belt 8.
In the present embodiment, belt stretcher 6 comprises regulating wheel 61, connecting rod 62, telescopic spring base 63 and tensioning spring 64.
Spring base 63 in the present embodiment comprises 631 and No. two pipes 632 of a pipe, 631 and No. two pipes of a pipe, 632 sockets, and can relative sliding, thus realize the Telescopic of spring base 63, the two ends of spring base 63 are equipped with limited block 633, for carrying out spacing to tensioning spring 64.
In the present embodiment, screen box 1 is arranged on base 2, screen box 1 bottom is provided with damping spring 7, vibrator 3 is fixed on screen box 1, vibrator 3 is connected by belt 8 with motor 4, connecting rod 62 one end are hinged on base 2, the other end and regulating wheel 61 are rotationally connected, regulating wheel 61 is tangent and be pressed on belt 8 with belt 8, in the outer rim of regulating wheel 61, have the draw-in groove 611 that prevents belt derailing, the cross sectional shape of the shape of draw-in groove 611 and belt 8 matches while using, belt 8 snaps in draw-in groove 611, spring base 63 one end are fixed on base 2, the other end is connected with connecting rod 62, spring base 63 two ends are provided with and are equipped with limited block 633, tensioning spring 64 is enclosed within on spring base 63 and between the limited block 633 at spring base 63 two ends and makes tensioning spring 64 have elastic potential energy, be that 63 pairs of connecting rods of spring base 62 keep certain thrust, thereby make belt 8 all the time in tensioning state.
In the present embodiment, in vibrator 3, be provided with three rotating shafts 31, these three rotating shafts 31 are equipped with pitch wheel 32, and the balancing weight 33 of equal eccentric mass, identical eccentric arm is housed on each gear 32.Due to the eccentric phase of three rotating shafts 31 with turn to not identically, produced the round orbiting motion of single shaft vibration and the straight-line resultant motion of dual-axis vibration, i.e. elliptic motion.The vibrating direction angle of this elliptic motion, vibration frequency and amplitude size all can be done the most reasonably to adjust according to the feature of institute's screening materials carrying.Its operational advantages is that bulk material is fast, be difficult for gambling hole, energy dehydration, de-mediated, desliming, the double grading with circular shale shaker and linear vibrating screen, compare with other kind screen(ing) machines of same specification and have that to take up an area space little, the advantage that disposal ability is large is the novel vibratory sieve with utmost point extensive use occasion.
