Description

Vibratory sieve
Technical field
The utility model belongs to machinery manufacturing technology field, specially refers to a kind of vibratory sieve.
Background technology
In occasions such as rock crushing plants, often can use vibratory sieve.Vibratory sieve utilizes the vibration that shock electric machine produces to work, and by changing the curve shape of compass screen surface movement locus and changing the movement locus of material on compass screen surface, realizes the screening of material.In general, vibratory sieve adopts shock electric machine drive shaft, and the vibrator being arranged on main shaft rotates with main shaft, 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 and the object of classification.But the installation more complicated of vibrator and main shaft, not only can improve the cost of vibratory sieve, and easily because the unstable potential safety hazard that produces is installed.
Summary of the invention
The purpose of this utility model is to propose a kind of simple in structure, vibratory sieve that cost is low, safe and reliable.
Vibratory sieve of the present utility model comprises base and the screen box on base by spring supporting, described screen box is provided with shock electric machine, screen cloth and main shaft, and key is that described main shaft comprises load-bearing shaft part and the counterweight shaft part between drive axle segments and load-bearing shaft part that two ends are exposed to the drive axle segments of screen box, by bearing, are connected with screen box; Described drive axle segments is connected with shock electric machine, and the cross section of drive axle segments is circular; The axial line of described load-bearing shaft part and counterweight shaft part is all eccentric in the axial line of drive axle segments; At grade, and the center of gravity of the center of gravity of described load-bearing shaft part, counterweight shaft part lays respectively at the both sides of the axial line of drive axle segments for the center of gravity of the center of gravity of described load-bearing shaft part, counterweight shaft part and the axial line of drive axle segments.
Shock electric machine drives drive axle segments to rotate, and load-bearing shaft part and balancer shaft segment sync are rotated, and because load-bearing shaft part is eccentric in the axial line of drive axle segments, so load-bearing shaft part can drive screen box to do the vibration of elliptical orbit while rotating, and realizes vibration screening; Simultaneously, due to the center of gravity of counterweight shaft part and the center of gravity opposite direction of load-bearing shaft part, can limit the movement locus of screen box, make its be similar to one end diameter greatly, one section of diameter is little and the droplet-shaped that seamlessly transits, not only improved amplitude, and improved screening effect.
Further, described counterweight shaft part is provided with some sections minutes shaft parts, and the center of gravity of described each minute shaft part is in the same plane, and the center of gravity of adjacent minute shaft part lays respectively at the both sides of the axial line of drive axle segments, further to improve the movement locus of screen box.
Further, described screen box is provided with the reinforcement that some roads are oblique and be arranged in parallel, and described reinforcement connects by connecting plate, and described spring is connected in the intersection of reinforcement and connecting plate.By reinforcement and connecting plate, can improve the intensity of screen box and spring junction, because reinforcement is oblique and be arranged in parallel, therefore vertical vibration force can be decomposed to other directions, further reduce the destruction of vibration to screen box, thereby improve security.
Further, described screen cloth has at least two-layer, to improve screening capacity.
Structure of Vibrating Screen of the present utility model is simple, utilizes eccentric shaft to realize vibration screening, and has improved security, has good practical value.

Fig. 1 is the structural representation of vibratory sieve of the present utility model.
Fig. 2 is the front view of main shaft of the present utility model.
Fig. 3 is the top view of main shaft of the present utility model.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
Embodiment 1:
As shown in the figure, the vibratory sieve of the present embodiment comprises base 1 and is supported in the screen box 3 on base 1 by spring 2, described screen box 3 is provided with shock electric machine 4, screen cloth and main shaft 5, and key is that described main shaft 5 comprises load-bearing shaft part 53 and the counterweight shaft part 52 between drive axle segments 51 and load-bearing shaft part 53 that two ends are exposed to the drive axle segments 51 of screen box 3, by bearing 6, are connected with screen box 3; Described drive axle segments 51 is connected with shock electric machine 4, and the cross section of drive axle segments 51 is circular; The axial line of described load-bearing shaft part 53 and counterweight shaft part 52 is all eccentric in the axial line of drive axle segments 51; At grade, and the center of gravity of the center of gravity of described load-bearing shaft part 53, counterweight shaft part 52 lays respectively at the both sides of the axial line of drive axle segments 51 to the axial line of the center of gravity of the center of gravity of described load-bearing shaft part 53, counterweight shaft part 52 and drive axle segments 51.
Shock electric machine 4 drives drive axle segments 51 to rotate, load-bearing shaft part 53 and counterweight shaft part 52 are synchronously rotated, because load-bearing shaft part 53 is eccentric in the axial line of drive axle segments 51, so load-bearing shaft part 53 can drive screen box 3 to do the vibration of elliptical orbit while rotating, and realizes vibration screening; Simultaneously due to the center of gravity of counterweight shaft part 52 and the center of gravity opposite direction of load-bearing shaft part 53, can limit the movement locus of screen box 3, make it be similar to the droplet-shaped that one end diameter is large, one section of diameter is little and seamlessly transit, not only improved amplitude, and improved screening effect.
Further, described counterweight shaft part 52 is provided with some sections minutes shaft parts, and the center of gravity of described each minute shaft part is in the same plane, and the center of gravity of adjacent minute shaft part lays respectively at the both sides of the axial line of drive axle segments 51, further to improve the movement locus of screen box 3.
Further, described screen box 3 is provided with the reinforcement that some roads are oblique and be arranged in parallel, and described reinforcement connects by connecting plate, and described spring 2 is connected in the intersection of reinforcement and connecting plate.By reinforcement and connecting plate, can improve the intensity of screen box 3 and spring 2 junctions, because reinforcement is oblique and be arranged in parallel, therefore vertical vibration force can be decomposed to other directions, further reduce the destruction of vibration to screen box 3, thereby improve security.
