Abstract
The utility model relates to a grading selection screen of grain processing, which belongs to grain processing machinery and is formed by a screen tank seated on an oscillator. The screen tank is formed by installing more than one layers of screening plates which are respectively connected to a collecting groove and a corresponding discharge opening inside a tank body, and a feeding opening is disposed on the top portion of a screen body. The oscillator is provided with a motor and eccentric gyrostats which are fixed on a frame, pulleys of the eccentric gyrostats are in belt linkage with a pulley of the motor, and the upper ends of the eccentric gyrostats are fixed at the bottom portion of the tank body. At least four layers of screening plates and the connected collecting grooves and corresponding discharge openings are installed inside the tank body, a guide plate arranged below each screening plate layer has a reversal dip angle with the same, and only the screening plate of the lowest layer has a dip angle with the same direction with the guide plate. One to three eccentric gyrostats are fixed at the bottom portion of the tank body and all in belt linkage with the motor. A belt linkage mechanism between the motor and the eccentric gyrostat is provided with a speed regulating tension device. The grading selection screen has the advantages of compact structure, stable performance, convenient operation, maintenance and cleaning, high whole grain extraction ratio and increased economic benefit.
Description
Technical field
The utility model relates to a kind of Cereals Processing Machines, especially grain processing classification recleaner screen.
Background technology
Raising along with people's living standard, people also improve day by day to the requirement of grain, are example with various rice classes, beans, and people are according to its form and nutritive value thereof, utilize grading machinery equipment that it is told different brackets, be chosen under the different environment for people and use.But because present picking equipment unreasonable structure makes grading effect undesirable, through the grain after the classification, the situation that various forms mix is also a lot, and of low quality, the market competitiveness of finished product grain are reduced, and influences the productivity effect of grain enterprise.Therefore need provide a kind of grain classifying screen, to reach grading effect more accurately.
Summary of the invention
Undesirable at existing grain classifying equipoment grading effect, product still has and mixes phenomenon in a large number after the classification, and the utility model provides a kind of grain processing classification recleaner screen, and the classification that is mainly used in cereal crops such as a meter class, beans is selected.It is to utilize to crack rice and the difference of whole grain of rice type, forms automatic classification when flowing on the compass screen surface of plane rotation, through the continuous screen of four layers of compass screen surface suitably being equipped with, isolate whole rice, big broken rice, in crack rice, small brokens or four grades of other grain.
The technical scheme that its technical problem that solves the utility model adopts is: grain processing classification recleaner screen, be on oscillator, to constitute by the screen box seat, screen box is that the sieve plate that is equipped with in casing more than one deck connects material collecting tank and corresponding discharging opening formation, charging aperture is arranged at the top of casing, oscillator is to have fixed motor and eccentric gyroscope wheel on frame, the belt pulley of eccentric gyroscope wheel and the belt pulley of motor link with belt, and the upper end of eccentric gyroscope wheel and the bottom of casing fix.
As further improvement of the utility model, the material collecting tank and the corresponding discharging opening of at least four layers of sieve plate and connection is housed in the casing, and each layer sieve plate following all there is deflector.
As further improvement of the utility model, sieve plate and deflector are reverse inclination angle mutually, wherein only have bottom sieve plate and deflector to have inclination angle in the same way.
As further improvement of the utility model, the bottom of casing fixed 1-3 eccentric gyroscope wheel and all with motor belt connection mutually.
As further improvement of the utility model, on the belt coupling mechanism of motor and eccentric gyroscope wheel the speed governing tensioning apparatus is arranged.
The beneficial effect that the utility model produces is: equipment not only has compact conformation, stable performance, operating maintenance conveniently, also because employing is extracted whole meter technology continuous three times, makes whole rice recovery rate height, thereby has improved economic benefit.

Fig. 2 is the front view of the utility model grain processing classification recleaner screen.
The specific embodiment
Grain processing classification recleaner screen, be on oscillator, to constitute by the screen box seat, screen box is that the sieve plate 2 that is equipped with in casing 1 more than one deck connects material collecting tank 3 and corresponding discharging opening 4 formations, charging aperture 5 is arranged at the top of casing 1, oscillator is to have fixed motor 7 and eccentric gyroscope wheel 8 on frame 6, the belt pulley of eccentric gyroscope wheel 8 and the belt pulley of motor 7 link with belt, and the bottom of the upper end of eccentric gyroscope wheel 8 and casing 1 fixes.Observation window can be equipped with in the casing top, the on-stream situation that can observe upper strata compass screen surface material.
The material collecting tank 3 and the corresponding discharging opening 4 that at least four layers of sieve plate 2 are housed in the casing 1 and connect, and each layer sieve plate 2 following deflector 9 is all arranged.Deflector 9 is set guarantees that feeding is even, and can reduce the impact of material, help automatic classification compass screen surface.
Sieve plate 2 is reverse inclination angle mutually with deflector 9, wherein only has bottom sieve plate 2 and deflector 9 to have inclination angle in the same way.
The bottom of casing 1 fixed 1-3 eccentric gyroscope wheel 8 and all with motor 7 belt connection mutually.
On the belt coupling mechanism of motor 7 and eccentric gyroscope wheel 8 speed governing tensioning apparatus 10 is arranged.Rotate tensioning apparatus, the centre-to-centre spacing between change speed governing belt wheel and the reducing gear moves up and down movable belt wheel thereupon under the pressure of spring, to change the contact diameter of speed governing belt wheel and vee-pulley, to reach the purpose of speed governing.By eccentvic rotation mechanism and the combination of frame gear frame, with supporting box, drive by transmission system, make casing do the plane rotation motion with certain radius.Because balance weight plays the balance box action of centrifugal force, so can make complete machine running balance.
