Description
Technical field
The utility model relates to a kind of screening machine.
Background technology
Screening machine is the relative motion that utilizes bulk granular material and compass screen surface, make the part particle see through sieve aperture, at present, use more screening machine to be drum sieve, its working portion that is used for screening is cylindrical shape, whole sieve turns round around tubular axis, axis is dressed up little inclination angle in the ordinary course of things, material feeds from an end of cylinder, thin rank material passes through from the sieve aperture of tubular working surface, and coarse-grained material is discharged from the other end of cylinder, and the rotating speed of drum sieve is very low, stable working, dynamic equilibrium is good, but its sieve aperture easily stops up, screening efficiency is low, has finally affected the quality of product after the screening.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of Circular-cylinder sieve extension set is provided.
For solving above technical problem, the utility model is taked following technical scheme:
A kind of screening machine, screening machine comprises base, has charging aperture and has the screen box of discharging opening, the driving mechanism that is arranged on the screen cloth in the screen box and drives screen box screening motion, wherein driving mechanism comprises driving shaft and the drive motors that links to each other at the bottom of the sieve with screen box, screening machine also comprise be separately positioned on first of driving shaft two ends stress piece and second stress piece and be arranged on base and screen box bottom between spring, wherein first stresses piece and second and stresses the side that piece is in driving shaft.
Preferably, first stresses piece and second stresses piece and is distributed in the driving shaft both sides, and the first weight that stresses piece stresses piece weight greater than second.
More preferably, the second weight that stresses piece is first to stress the twice of piece weight.
Preferably, screen cloth is divided into the screening layered that is positioned at the top with screen box and is positioned at the sieve bottom of below, and wherein the sidepiece of screening layered and sieve bottom is respectively equipped with discharging opening.
More preferably, bottom and the horizontal direction of sieve bottom form angle, and discharging opening forms angle along sieve bottom bottom with horizontal direction and stretches out very convenient blanking.
Further preferably, the angle of the bottom of sieve bottom and horizontal direction formation angle is 15～45 °.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
The utility model adopt set up the driving shaft two ends stress piece and be arranged on base and the sieve bottom between spring, under the rotation of driving shaft, improved Oscillation Amplitude and the frequency of screen box, reduced the screen cloth clogging, and then improved screening efficiency.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in more detail:
Fig. 1 is the structure partial cross-sectional schematic according to the utility model screening machine;
Wherein: 1, base; 2, screen box; 20, charging aperture; 21, discharging opening; 22, screening layered; 23, sieve bottom; 3, screen cloth; 4, driving mechanism; 40, driving shaft; 41, drive motors; 5, first stresses piece; 6, second stresses piece; 7, spring.
The specific embodiment
As shown in Figure 1, screening machine according to present embodiment, it comprises base 1, the upper end has the screen box 2 that charging aperture 20 and both sides have discharging opening 21, be arranged on the screen cloth 3 in the screen box 2, and the driving mechanism 4 that drives screen box 2 screening motions, wherein driving mechanism 4 comprises driving shaft 40 and the drive motors 41 that links to each other at the bottom of the sieve with screen box 2, screen cloth 3 is divided into the screening layered 22 that is positioned at the top and the sieve bottom 23 that is positioned at the below with screen box 2, wherein the sidepiece of screening layered 22 and sieve bottom 23 is respectively equipped with discharging opening 21, and bottom and the horizontal direction of sieve bottom form 15～45 ° of angles, discharging opening forms angle along sieve bottom bottom with horizontal direction and stretches out, very convenient blanking, simultaneously screening machine comprises that also being separately positioned on first of driving shaft 40 two ends stresses piece 5 and second and stress piece 6 and be arranged on base 1 and the spring 7 that sieves between the bottom 23, wherein first stresses piece 5 and second and stresses piece 6 and be distributed in driving shaft 40 both sides, and the first weight that stresses piece 5 stresses piece 6 weight greater than second, set up spring 6 and be for the screening amplitude that increases screen box 2 and better support whole screen box 2, the second weight that stresses piece 6 is first to stress the twice of piece 5 weight in the present embodiment.
The screening machine of present embodiment, material is inserted in the screen box 2 from charging aperture 20, employing arranges first of driving shaft 40 two ends and stresses piece 5 and second and stress piece 6, under the drive of drive motors 41, the rotation of driving shaft 40, thereby drive screen box 2 levels, vertically, the three-D motion of tilting, and under the effect of spring 7, improve the screening amplitude, improve the screening frequency of screen cloth 3, discharged from the discharging opening 21 of screening layered 22 greater than the material in screen cloth 3 apertures, dropped down onto sieve bottom 23 less than the particle diameter of screen cloth 3, discharge particle diameter less than the material in screen cloth 3 apertures by sieve bottom 23 and the discharging opening 21 of screening layered 22 opposite sides again, thereby realize the screening purpose.
