Description
Technical field
The invention belongs to machinery manufacturing technology field, be related specifically to a kind of vibratory sieve.
Background technology
In occasions such as rock crushing plants, often vibratory sieve can be used.The vibration that vibratory sieve utilizes shock electric machine to produce works, 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 be 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, thus reaches and to screen material 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 produce potential safety hazard because installing instability.
Summary of the invention
The object of the invention is to propose the vibratory sieve that a kind of structure is simple, cost is low, safe and reliable.
Vibratory sieve of the present invention comprises base and by the screen box of spring supporting on base, described screen box is provided with shock electric machine, screen cloth and main shaft, and key is that described main shaft is comprised two ends and is exposed to the drive axle segments of screen box, the load-bearing shaft part be connected with screen box by bearing and the counterweight shaft part between drive axle segments and load-bearing shaft part; 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 described load-bearing shaft part, the center of gravity of counterweight shaft part lay respectively at the both sides of the axial line of drive axle segments to the axial line of the center of gravity of described load-bearing shaft part, the center of gravity of counterweight shaft part and drive axle segments.
Shock electric machine drives drive axle segments to rotate, and load-bearing shaft part and balancer shaft segment sync is rotated, because load-bearing shaft part is eccentric in the axial line of drive axle segments, screen box can be driven to do the vibration of elliptical orbit, realize vibration screening when therefore load-bearing shaft part rotates; Simultaneously because the center of gravity of counterweight shaft part is contrary with the center of gravity direction of load-bearing shaft part, the movement locus of screen box can be limited, make its be similar to one end diameter greatly, the little and droplet-shaped seamlessly transitted of one section of diameter, not only increase amplitude, and improve screening effect.
Further, described counterweight shaft part is provided with some sections points of shaft parts, and the center of gravity of described each point of shaft part is in the same plane, and the center of gravity of adjacent point of shaft part lays respectively at the both sides of the axial line of drive axle segments, to improve the movement locus of screen box further.
Further, described screen box is provided with some roads reinforcement oblique and arranged in parallel, and described reinforcement is connected by connecting plate, and described spring is connected to the intersection of reinforcement and connecting plate.By reinforcement and connecting plate, the intensity of screen box and spring junction can be improved, because reinforcement is oblique and arranged in parallel, therefore vertical vibration force can be decomposed other directions, reduce the destruction of vibration to screen box further, thus improve security.
Further, described screen cloth has at least two-layer, to improve screening capacity.
Structure of Vibrating Screen of the present invention is simple, utilizes eccentric shaft to achieve vibration screening, and improves security, have good practical value.

Fig. 1 is the structural representation of vibratory sieve of the present invention.
Fig. 2 is the front view of main shaft of the present invention.
Fig. 3 is the top view of main shaft of the present invention.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in the figure, the vibratory sieve of the present embodiment is comprised 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 is comprised two ends and is exposed to the drive axle segments 51 of screen box 3, the load-bearing shaft part 53 be connected with screen box 3 by bearing 6 and the counterweight shaft part 52 between drive axle segments 51 and load-bearing shaft part 53; 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 described load-bearing shaft part 53, the center of gravity of counterweight shaft part 52 lay respectively at the both sides of the axial line of drive axle segments 51 to the axial line of the center of gravity of described load-bearing shaft part 53, the center of gravity of counterweight shaft part 52 and drive axle segments 51.
Shock electric machine 4 drives drive axle segments 51 to rotate, make load-bearing shaft part 53 and counterweight shaft part 52 synchronous axial system, because load-bearing shaft part 53 is eccentric in the axial line of drive axle segments 51, screen box 3 can be driven when therefore load-bearing shaft part 53 rotates to do the vibration of elliptical orbit, realize vibration screening; Simultaneously because the center of gravity of counterweight shaft part 52 is contrary with the center of gravity direction of load-bearing shaft part 53, the movement locus of screen box 3 can be limited, one end diameter is large, one section of diameter is little and the droplet-shaped seamlessly transitted to make it be similar to, and not only increases amplitude, and improves screening effect.
Further, described counterweight shaft part 52 is provided with some sections points of shaft parts, and the center of gravity of described each point of shaft part is in the same plane, and the center of gravity of adjacent point of shaft part lays respectively at the both sides of the axial line of drive axle segments 51, to improve the movement locus of screen box 3 further.
Further, described screen box 3 is provided with some roads reinforcement oblique and arranged in parallel, and described reinforcement is connected by connecting plate, and described spring 2 is connected to the intersection of reinforcement and connecting plate.By reinforcement and connecting plate, screen box 3 and the intensity of spring 2 junction can be improved, because reinforcement is oblique and arranged in parallel, therefore vertical vibration force can be decomposed other directions, reduce the destruction of vibration to screen box 3 further, thus improve security.
