A kind of vibrating crushing screening machine
Technical field
The utility model relates to a kind of vibrating crushing screening machine.
Background technology
At present at the powder metallurgy industry, the swing crushing equipment that adopts is main is to utilize to have the granular mixed material that poroid or slot-shaped working face will vary in size and carry out classification, material screening can be classified as finished product during work, also can do classification for next procedure and prepare.The unconspicuous situation of material crushing often can occur in existing swing crushing equipment in power production, inefficiency is not only influential to the apparent density of product, and this type of machinery production technique is loaded down with trivial details, is unfavorable for large-scale production.
The utility model content
The purpose of this utility model provides a kind of vibrating crushing screening machine, and this vibrating crushing screening machine is simple in structure, be convenient to make, and solves the unconspicuous problem of material crushing.
The technical solution adopted in the utility model is: a kind of vibrating crushing screening machine, it comprises screen box, be fixedly connected with support on the described screen box, described screen box upper surface one end is fixed with feed hopper, the other end is provided with screen cloth, described screen box is fixed with discharging opening away from an end of feed hopper, described discharging opening comprises the first discharging opening, the second discharging opening, described screen box lower surface center projections forms cone, the cone outer wall is fixed with two vibrators near the feed hopper place, and the axis of two vibrators coincides.
As further improvement of the utility model, described support is provided with damping spring.
As further improvement of the utility model, described screen cloth is stainless steel mesh.
The beneficial effect that the utility model adopts is: after having adopted this structure, because the axis of two vibrators coincides, when two motors do synchronously, when counter-rotating, the exciting force that its eccentric block produces is cancelled out each other in the direction of the axis that is parallel to vibrator, be stacked as one in the direction perpendicular to the vibrator axis and make a concerted effort, so the movement locus of screen(ing) machine is a straight line; Vibrator is arranged on the side of cone, there is certain angle on the side of cone and plane, screen cloth place, therefore material at exciting force and material under the force action of gravity, material is tossed great-jump-forward moving linearly forward on compass screen surface, thereby reach material is screened purpose with classification, this vibrating crushing screening machine is simple in structure, be convenient to make, and solved the unconspicuous problem of material crushing; When the damping spring that arranges has reduced vibrating crushing screening machine work to the impact of board; Adopt stainless steel mesh can prolong the service life of screen cloth.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the top view of Fig. 1.
Shown in the figure: 1 screen box, 2 supports, 3 feed hoppers, 4 screen clothes, 5 first discharging openings, 6 second discharging openings, 7 cones, 8 vibrators, 9 damping springs.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, a kind of vibrating crushing screening machine, it comprises screen box 1, be fixedly connected with support 2 on the described screen box 1, described support 2 is provided with damping spring 9, described screen box 1 upper surface one end is fixed with feed hopper 3, the other end is provided with screen cloth 4, described screen cloth 4 is stainless steel mesh, described screen box 1 is fixed with discharging opening away from an end of feed hopper 3, described discharging opening comprises the first discharging opening 5, the second discharging opening 6, described screen box 1 lower surface center projections forms cone 7, and the axis that cone 7 outer walls locate to be fixed with 8, two vibrators of two vibrators near feed hopper (3) coincides.
After having adopted this structure, when producing, material is poured into by feed hopper 3, carry out crushing and screening at screen cloth, because the axis of two vibrators coincides, when two motors do synchronously, when counter-rotating, the exciting force that its eccentric block produces is cancelled out each other in the direction of the axis that is parallel to vibrator, be stacked as one in the direction perpendicular to the vibrator axis and make a concerted effort, so the movement locus of screen(ing) machine is a straight line; Vibrator is arranged on the outer wall of cone, there is certain angle on the outer wall of cone and plane, screen cloth place, therefore material at exciting force and material under the force action of gravity, material is tossed great-jump-forward moving linearly forward on compass screen surface, do not poured out by the first discharging opening 5 by the large-scale particle of vibratory sieve veil, pour out through crushed particles first discharging opening 6 of vibratory sieve veil, thereby reach material is screened purpose with classification.In sum, this vibrating crushing screening machine is simple in structure, be convenient to make, and solved the unconspicuous problem of material crushing; When the damping spring that arranges has reduced vibrating crushing screening machine work to the impact of board; Adopt stainless steel mesh can prolong the service life of screen cloth.
