Abstract
An oscillating sieve is composed of enclosed casing, sieving case, sieving net fixed in sieving case, oscillator linked to sieving case, and the sieving case supporter consisting of connectors and springs.
Description
Technical field
The present invention relates to sieving machine, relate in particular to a kind of vibratory sieve.
Background technology
Along with the fast development that highway in China is built, increasing with the demand of bituminous concrete to road surface pavement, quality requirement is also more and more higher.On the engineering, bituminous concrete adopts plant mix equipment production mostly, and vibratory sieve is one of critical component wherein.Vibratory sieve be by vibration with building stones by the size classification, use and often it to be arranged on the top of mixing and stirring tower, make by its vibration and mix and stir rocking that tower produces, often make mixing and stirring the people who works on the tower and feel dangerous.
Summary of the invention
The objective of the invention is: provide a kind of the use reliably and to vibrate little vibratory sieve its attachment.
For achieving the above object, technical scheme of the present invention is: vibratory sieve, comprise: the screen box of fixed grit, screen box is connected with the vibratory sieve housing that screen box is sealed by the screen box bracing or strutting arrangement, screen box is connected with device of excitation, described device of excitation is positioned at vibratory sieve hull outside upside, described screen box bracing or strutting arrangement comprises first Connection Block that is connected with screen box and second Connection Block that is connected with the vibratory sieve housing, be provided with first support spring and second support spring between first Connection Block and second Connection Block, the axis of first support spring and second support spring lays respectively at vertical guide both sides and has angle with this vertical guide respectively.
Owing to adopted technique scheme, when first support spring is subjected to exciting force perpendicular to its axis direction, because the axis of first support spring and second support spring has angle, so second support spring will be subjected to bigger exciting force at its axis direction, thereby improved the stress condition of first support spring; When second support spring is subjected to exciting force perpendicular to its axis direction, first support spring will be subjected to bigger exciting force at its axis direction, thereby improve the stress condition of second support spring, so just improve the dependability of each support spring.Simultaneously, because the axis of first support spring and second support spring has angle, passing to the vibration of the horizontal direction of vibratory sieve housing by support spring like this will be by partial offset, so pass to the vibration of the horizontal direction of its attachment also reduces by the vibratory sieve housing, thereby reduced the horizontal jitter of vibratory sieve attachment, made mixing and stirring the people who works on the tower to feel safe.
As a kind of improvement, device of excitation is made as the first vibrating device and second device of excitation of rotation in opposite directions.Because it rotates in opposite directions, thus from the starting of oscillation source, the oscillating component of horizontal direction is offset, thus further reduce horizontal jitter to the vibratory sieve attachment, make mixing and stirring the people who works on the tower and feel safer.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is the structural representation of the embodiment of the invention.
The specific embodiment
As shown in drawings, vibratory sieve, comprise: the screen box 4 of fixed grit, screen box 4 is connected with the vibratory sieve housing 1 that screen box 4 is sealed by screen box bracing or strutting arrangement 5, screen box bracing or strutting arrangement 5 comprises first Connection Block 3 that is connected with screen box 4 and second Connection Block 2 that is connected with vibratory sieve housing 1, the axis that is provided with first support spring 51 and second support spring, 52, the first support springs 51 and second support spring 52 between first Connection Block 3 and second Connection Block 2 lays respectively at vertical guide both sides and has angle with this vertical guide respectively.Screen box 4 is connected with device of excitation 6, device of excitation 6 comprises the first vibrating device and second device of excitation of rotation in opposite directions, lay respectively at vibratory sieve housing 1 external upper, the first vibrating device comprises the first starting of oscillation axle 61a, and the first starting of oscillation axle 61a is connected with the first motor 61c that is located at vibratory sieve housing 1 external upper by the first belt driver 61b; Second device of excitation comprises the second starting of oscillation axle 62a, and the first starting of oscillation axle 62a is connected with the second motor 62c that is located at vibratory sieve housing 1 external upper by the second belt driver 62b.For low power vibratory sieve, device of excitation can be made as vibrating motor, can make device of excitation 6 simple in structure like this.
When first support spring 51 is subjected to exciting force perpendicular to its axis direction, because the axis of first support spring 51 and second support spring 52 has angle, so second support spring 52 will be subjected to bigger exciting force at its axis direction, thereby improved the stress condition of first support spring 51; When second support spring 52 is subjected to exciting force perpendicular to its axis direction, first support spring 51 will be subjected to bigger exciting force at its axis direction, thereby improved the stress condition of second support spring 52, so just improved the dependability of each support spring.Simultaneously, because the axis of first support spring 51 and second support spring 52 has angle, passing to the vibration of the horizontal direction of vibratory sieve housing 1 by support spring like this will be by partial offset, so pass to the vibration of the horizontal direction of its attachment also reduces by vibratory sieve housing 1, thereby reduced the horizontal jitter of vibratory sieve attachment, made mixing and stirring the people who works on the tower to feel safe.Because the first vibrating device and second device of excitation rotate in opposite directions, thus from the starting of oscillation source, the oscillating component of horizontal direction is offset, thus further reduce horizontal jitter to the vibratory sieve attachment, make mixing and stirring the people who works on the tower and feel safer.
