Abstract
The present invention relates to a bifunctional single vibrating sieve for the separation and the conveyance of rice grain stems or sand stone particles, which provides a technical scheme integrating the functions of sieving and conveyance into a whole. The technical scheme is realized through the up-and-down vibration (through the locking of the range of a swinging angle of rocking arms) in a single direction of the sieve during the forward and backward vibration of the sieve. The present invention can achieve the purpose that during the separation of materials, the remnant materials can be automatically conveyed out of the sieve horizontally and even upwards and slantways (without conveying belts). The present invention is particularly suitable for the automatic separation link on an agricultural and industrial production line or the independent separation work in agricultural and industrial production.
Description
Technical field:
The present invention relates to rod granule and grain sorting and level or updip and carry the suspension type monomer vibratory sieve technology that is integrated in one.
Background technology:
At present, in agro-industry, for separating such as paddy in the grain agricultural products of paddy and bar, and the separating of the sandstone granular size in mining and the building industry, above-mentioned separation link as in the production and processing has realized mechanization basically, and mostly adopts the vibratory drilling method screening.Its deficiency be: in above-mentioned separation link, the leftover materials after separated are difficult to be gone out by automatic transport.If the leftover materials deadweight is bigger, still can rely on certain gradient that their coastings are gone out, but this just must increase the height that this separates job site in the link, and by the hoisting depth of sorting material before sorting; If the leftover materials deadweight is less, perhaps very light, for example: the tiny assorted bar of paddy, inclination downslide carrying method is also not necessarily effective, and this will rely on other very unfavorable means or additional process to assist just can finish again.This tends to form the difficult problem on the automatic production line, just becomes " eck " link in the unimpeded road on the production line.
The example that problem can be described: just as the common workman to the construction site of people with sieve front and back back and forth the vibration screening fine sand in the horizontal direction, after fine sand screens, also to increase by one with remaining rough sand overturning special action local to another place be again.If can omit this " special action ", that is: the process of screening fine sand just remains rough sand and automatically is transported to the local process in another place, and " eck " of above-mentioned this unimpeded road just do not existed.Obviously, this is the screening process state that people wish most, and is particularly all the more so in the screening of this on the automatic production line link.
US4807487 (1986) discloses a kind of technical solution (the double horizontal feed of screening) for addressing the above problem, its deficiency is: realize that by its astable type " vibration of rocking arm jacking sieve nest " version and complicated " eccentric Driven by Coaxial " (eccentric wheel and front arm or rear arm are positioned on the same back shaft) formed structural principle of system the double horizontal feed of its screening is bifunctional, the mechanical structure principle of employing is not satisfactory.
DE19623358 A (1996) discloses a kind of conventional art (screening the double conveying that has a down dip) of continuing to use, the pendulum angle scope of its rocking arm relates to two quadrants (with rectangular coordinate system vertical and that horizontal direction constitutes), the weak point of its structure for conveying that has a down dip, preamble has explanation, but on its structure, it has adopted the very reasonably technical pattern of rocking arm suspension sieve nest vibration, is desirable.
Summary of the invention:
The present invention is a kind of improvement (the very simple modulator approach when technological core is key member work) on the DE19623358A technical foundation, makes it more become rationally perfect, to reach the purpose that makes it to enter the desirable practical stage.
The present invention is achieved in that
It structurally comprises at least: mass transport screen tray and hang its front arm or rear arm, and drive (eccentric wheel is not positioned at the version that same separate type on the back shaft drives with front arm or rear arm) system by the separate type eccentric dynamic that drive rod, eccentric wheel and motor constitute to the mass transport screen tray that hangs.
It is characterized in that the control method requirement during rocking arm work is:
Above-mentioned front arm or (with) the pendulum angle scope of rear arm is limited in the quadrant, when the horizontal positive direction of mass transport screen tray is shaken when capable, its row that upwards shakes simultaneously, when mass transport screen tray level is shaken when capable in the other direction, its row that shakes downwards simultaneously.
Characteristics of the present invention:
On the structure, make sieve nest be under the prerequisite of suspended vibration duty of natural stability type, the rocking arm vibration angle that will hang sieve nest again is limited in the quadrant, not only this just makes the vibration sieve nest can carry out screening operation, the dual-use function that can also executive level be fed forward screened material, even can also reach the fancy effect that screened material updip is carried, obviously, the method for so simple " qualification vibration angle " has just been created condition for the present invention enters the convenient practical stage.
Description of drawings:
Fig. 1 has illustrated the operation principle of key position of the present invention (sieve nest).
Fig. 2 is as a kind of independent type embodiment of the present invention, illustrated its complete machine structure by its complete section front view and vertical view.A: mass transport screen tray; B: front arm; C: rear arm; D: drive rod; E: eccentric wheel; P: rocking arm back shaft; L: horizontal vibration amplitude; H: vertical amplitude; A: pendulum angle; 1: node movingly; 2: remaining large granular materials; 3: the small particles material of screening; 4: motor; 5: feed arrangement (material of input desire screening); 6: body; 7: support; 8: wheel; 9: funnel (collection small particles material); 10: drawing mechanism (output large granular materials).
The specific embodiment:
By sieve nest operation principle shown in Figure 1:
Front arm (B) and rear arm (C) are the location, lower end, and the upper end is in the structural shape of support mass transport screen tray (A), front arm wherein (B) is made of the both arms that are positioned at about mass transport screen tray (A), and rear arm (C) is made of the single armed that is positioned at mass transport screen tray (A) middle part.Drive rod (D) makes mass transport screen tray (A) vibration work by directly driving rear arm (C).
The scope of the angle of oscillation the during work of front arm (B) and rear arm (C) is all in first quartile, and when front arm (B) and rear arm (C) when being in vertical position, mass transport screen tray (A) also just in time is in the extreme higher position.When mass transport screen tray (A) shakes when capable from low to high and forward, the not screened remaining large granular materials (2) that comes out will be thrown to the place ahead by mass transport screen tray (A), send through throwing forward repeatedly, make remaining large granular materials (2) finally will be transferred out mass transport screen tray (A); The screened small particles material (3) that goes out sieves from mass transport screen tray (A) and leaks down, and is thereunder got up by centralized collection.
The process of this separation screening small particles material (3) and large granular materials (2) can be carried out constantly.Change horizontal amplitude (L) and the vertical amplitude (H) of mass transport screen tray (A) if desired, only need to change front arm (B) and rear arm (C) length or (with) their pendulum angle (a) gets final product.
Be under the duty like this, even if mass transport screen tray (A) updip is placed, that is: preceding (left end) high back (right-hand member) is low, and remaining large granular materials (2) also can finally be sent the left end of mass transport screen tray (A) through repeatedly after upthrow is capable.
