Description
Technical field
The utility model belongs to screening plant, particularly a kind of linear vibrating screen uniform distribution device.
Background technology
Most of linear vibrating screens are for the consideration of screening efficiency and disposal ability, screen angle is generally less, make like this material time of staying on compass screen surface longer, can realize sufficient screening, yet can bring like this drawback, the move forward difficulty of material on compass screen surface strengthens, there is a large amount of solid accumulations at the oscillating screen place of chute material mouth below, affect the normal mobile and screening of material, reduced screening efficiency, secondly, the compass screen surface width of most large-scale straight-line oscillations is 2 ~ 3 meters, the chute width of charging gear depends primarily on conveyer belt width, be generally 1 meter of left and right, the compass screen surface width of large-scale straight-line oscillation is often 2 ~ 3 times of feed chute width, therefore, the material great majority that drop into compass screen surface concentrate on the middle part of compass screen surface, and both sides exist large area there is no the region of material, material skewness causes effective sifting area to reduce, screening materials carrying Efficiency Decreasing, also cause compass screen surface middle part serious wear and the middle part fatigue rupture of lower support crossbeam larger simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, avoids material to concentrate and piles up, and can improve the straight-line oscillation uniform distribution device of screening efficiency.
The new technical scheme of understanding certainly technical problem employing of this practicality is: linear vibrating screen uniform distribution device comprises linear vibrating screen, feeding groove, motor, worm type of reduction gearing, be characterized in that motor connects worm type of reduction gearing, worm type of reduction gearing output shaft is by the rotating shaft of shaft coupling connecting crank, crankshaft is by one end of key connecting crank, the other end of crank is hinged the lower end of connecting rod by hinge two, the upper end of connecting rod is hinged the right-hand member of rocking bar by hinge one, the centre of rocking bar is flexibly connected a back shaft with stop nut, back shaft lower end is fixed on to be supported on axle bed, rocking bar left end dress rocking bar reinforcement, rocking bar left end lower end is fixedly connected with a driving lever, driving lever is placed in the compass screen surface top of linear vibrating screen.
The beneficial effects of the utility model are: linear vibrating screen uniform distribution device can effectively solve a difficult problem for a large amount of solid accumulations in chute feeding mouth corresponding position on compass screen surface, and material too concentrates middle part to cause the both sides of compass screen surface to have a difficult problem for material blind area on compass screen surface, screening efficiency and service life of equipment have been improved.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is linear vibrating screen uniform distribution device structure chart.
In figure, 1-linear vibrating screen; 2-feeding groove; 3-stop nut; 4-rocking bar; 5-hinge one; 6-connecting rod; 7-key; 8-hinge two; 9-crank; 10-crankshaft; 11-shaft coupling; 12-worm type of reduction gearing; 13-motor; 14-back shaft; 15-supports axle bed; 16-rocking bar reinforcement; 17-driving lever.
The specific embodiment
Embodiment, with reference to accompanying drawing 1, the motor 13 of linear vibrating screen uniform distribution device connects worm type of reduction gearing 12, the output shaft of worm type of reduction gearing 12 is by shaft coupling 11 connecting crank rotating shafts 10, crankshaft 10 is by one end of key 7 connecting cranks 9, and the other end of crank 9 is by the lower end of hinge 28 articulated linkage 6.The upper end of connecting rod 6 is hinged the right-hand member of rocking bar 4 by hinge 1, in the middle of rocking bar 4, with stop nut 3, be flexibly connected a back shaft 14, and the lower end of back shaft 14 is fixed on to be supported on axle bed 15.Rocking bar reinforcement 16 is equipped with in rocking bar 4 left end welding, and rocking bar 4 left end lower ends are welded to connect a driving lever 17, and driving lever 17 is placed in the compass screen surface top of linear vibrating screen 1, and feeding groove 2 is equipped with in the top of linear vibrating screen 1.
The course of work of linear vibrating screen uniform distribution device is: material is slipped in linear vibrating screen 1 via feeding groove 2, and there is solid accumulation at the linear vibrating screen 1 compass screen surface place of the feed opening of feeding groove 2 below.Actuating motor 13 band worm type of reduction gearings 12, through worm type of reduction gearing 12 deceleration crankshafts 10, rotate, crankshaft 10 is connected and is driven crank 9 to move in a circle by key 7, crank 9 passes motion to connecting rod 6, connecting rod 6 drives rocking bar 4 to rotate at a certain angle around back shaft 14 upper ends, rocking bar 4 drives driving lever 17 to swing, driving lever 17 is stirred the material of accumulation, material is evenly spread out, and to compass screen surface two side shiftings of linear vibrating screen, material is evenly distributed on the compass screen surface of linear vibrating screen 1.
