Abstract
The utility model relates to scale sifting equipment of the fields of feed, food, chemical industry, medicine and the like, in particular to a vibration sifting screen. The vibration sifting screen comprises a barrel-shaped sieve body and a machine frame. A feeding opening and a material discharging opening are arranged in the sieve body. A main shaft is arranged in the sieve body and a plurality of material striking plates are fixedly arranged on the main shaft in the sieve body. Two ends of the main shaft extend out of the sieve body and are connected with the machine frame through elastic supporting mechanisms. One end of the main shaft is connected with a driving device in a revolving mode. The main shaft is connected with the end portion of the sieve body through an eccentric block in a revolving mode. The elastic supporting mechanisms are two groups arranged in a bilateral symmetry mode. Each group of the elastic supporting mechanisms comprises a big spring arranged on the machine frame at two ends of the sieve body in a front and back mode. A spring beam is arranged on the upper side of the big spring. The middle portion of the spring beam is connected with the main shaft through a bearing seat in a revolving mode. Each small spring is arranged at two ends of the upper side of the spring beam. The small springs are respectively fixedly connected with the sieve body through a connecting plate. The vibration sifting screen is simple in structure. Sieve holes are not easy to be blocked when materials are sifted in a superfine scale mode.
Description
Technical field
The utility model relates to the sizing screening equipment of feed, food, chemical industry, medicine and other fields, particularly a kind of vibration sifting screen.
Background technology
Super-fine classified sieve is a kind of classification cleaning equipment, is mainly used in the screening of material, and fibrous material that particle larger in material and proportion are lighter etc. is removed in classification, prevents that latter equipment from stopping up.
Super-fine classified sieve has two motors to drive respectively spindle rotor and screen drum rotates, the surrounding of rotor is equipped with adjustable the re-packing of several angles, the feeding auger of material in charging aperture is transported to screen drum inside, the rotor of high speed rotating is broken material to compass screen surface, and material is sieved fast, and the screen drum of rotor rotating in same direction can increase the touch opportunity of material and screen drum, material is more easily sieved, but this device need to drive respectively and control two motors, structure and annexation complexity, manufacturing cost is higher.
Vibratory sieve is in the process of screening, and material relative compass screen surface in vibratory sieve is done continuous beating, and the material that is less than screen size passes through sieve aperture in hopping process, thereby reaches the purpose of screening.In current material sieving technology, vibrosieve is much, but the application aspect super-fine classified is unsatisfactory, yields poorly and easily stops up sieve aperture.
The utility model content
The problem that the utility model exists for prior art, provide a kind of simple in structure, control and vibrate easily sifting screen, and be not easy to stop up sieve aperture when super-fine classified material screening.
The purpose of this utility model is to realize like this, a kind of vibration sifting screen, comprise tubular sieve nest and frame, described sieve nest is provided with charging aperture and discharging opening, be provided with main shaft in sieve nest, be fixed with several knockout plates on main shaft in sieve nest, stretch out outside sieve nest at described main shaft two ends, by elastic supporting mechanism, with frame, be connected, described main shaft one end and drive unit are rotationally connected, described main shaft and sieve nest end are rotationally connected by eccentric block, described elastic supporting mechanism is two groups that are symmetrical set, the big spring that every group of elastic supporting mechanism arranges before and after being included on the frame at sieve nest two ends, described big spring upside is provided with the spring beam, described spring beam middle part is rotationally connected by bearing block and main shaft, the two ends of spring beam upside respectively are provided with a little spring, described little spring is fixedly connected with sieve nest by connecting plate respectively.
In the utility model, sieve nest is dither under the effect of the main shaft of high speed rotating and eccentric block, simultaneously, the vibration of sieve nest is delivered on the spring beam by main shaft and bearing block, make the spring beam produce corresponding vibration, little spring on the spring beam plays certain formulation effect by connecting plate to the vibration of sieve nest, thereby make sieve nest produce stable high frequency, vibrates by a narrow margin; During the main shaft high speed rotating, the knockout plate on the sieve nest inner main axis is constantly broken the material in screen drum to compass screen surface, and material is sieved fast.So the beneficial effects of the utility model are: the dither of sieve nest, not only accelerate the speed of sub-sieve, also effectively avoided the feed blocking sieve aperture.Be particularly suitable in the ultra-fine sub-sieve of all kinds of materials.
For preventing that the spring beam is offset in vibration, be connected with the position-limited rack for restraining spring beam amplitude and direction between described spring beam and frame, described position-limited rack and spring beam junction are provided with Flexible Connector.
For guaranteeing the stable operation of transmission system, described main shaft is connected by tape handler with drive unit, and described belt gear is provided with swelling device.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The partial enlarged drawing that Fig. 2 is A place in Fig. 1.
Fig. 3 is the right view of figure A.
Wherein, 1 sieve nest; 2 connecting plates; 3 little springs; 4 spring beams; 5 big springs; 6 discharging openings;
7 frames; 8 position-limited racks; 9 main shafts; 10 bearing blocks; 11 charging apertures.
The specific embodiment
As Fig. 1, Fig. 2 and Figure 3 shows that vibration sifting screen of the present utility model, comprise tubular sieve nest 1 and frame 7, sieve nest 1 is provided with charging aperture 11 and discharging opening 6, be provided with main shaft 9 in sieve nest 1, be fixed with several knockout plates on main shaft 9 in sieve nest 1, stretch out outside sieve nest 1 at main shaft 9 two ends, by elastic supporting mechanism, with frame 7, be connected, main shaft 9 one ends are connected by tape handler with drive unit, and described belt gear is provided with swelling device, main shaft 9 is rotationally connected by eccentric block with sieve nest 1 end, elastic supporting mechanism is two groups that are symmetrical set, the big spring 5 that every group of elastic supporting mechanism arranges before and after being included on the frame 7 at sieve nest 1 two ends, big spring 5 upsides are provided with spring beam 4, spring beam 4 middle parts are rotationally connected by bearing block 10 and main shaft 9, the two ends of spring beam 4 upsides respectively are provided with a little spring 3, little spring 3 is fixedly connected with sieve nest 1 by connecting plate 2 respectively, for preventing the skew of spring beam, be connected with the position-limited rack 8 for restraining spring beam amplitude and direction between spring beam 4 and frame 7, position-limited rack 8 is provided with Flexible Connector with spring beam 4 junctions.
