Abstract
The utility model discloses a rice cleaning and screening device. The rice cleaning and screening device comprises a rack, an eccentric transmission device and a screen shaking mechanism. The screen shaking mechanism is obliquely installed between an outlet of a conveying channel and a grain receiving port and drives a rear screen shaking mechanism through the eccentric transmission device to make reciprocating motion and longitudinal shaking at the same time so that grains containing impurities on a screen plate can move forwards to an impurity discharge port in a jumping mode, material can be fully shaken to be scattered, the defect that screen holes of a traditional vibrating screen are blocked is overcome while a scraper blade or a fan is not arranged, meanwhile, a plurality of rows of impurity discharge plates are arranged on the screen plate at intervals, the grains can be graded and screened irreversibly, and the impurity rate and the loss rate of screening can be obviously reduced.
Description
Technical field
The utility model relates to rice processing equipment technical field, is specifically related to a kind of paddy sorting screen separating device.
Background technology
The process of rice is generally divided into the operations such as cleaning, ridge paddy, husk rice and finished product processing, and wherein cleaning is a master operation in paddy processing, cleans the critical process that screening is rice processing.Tradition paddy sorting screen separating device adopts the back and forth vibratory sieve of transverse movement, and sieving capacity is low, and percentage of impurity is high, and mesh easily stops up, even if be provided with scraper plate or blower fan, the effect of screening is still poor, has increased the workload of follow-up selected work.Therefore, develop a kind of simple in structure, easy and simple to handle, foreign material sorting thoroughly paddy sorting screen separating device be desirability.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy and simple to handle, foreign material sorting paddy sorting screen separating device is thoroughly provided.
The purpose of this utility model is to realize like this, this sorting screen separating device comprises frame and radial gear and trembles screening mechanism, trembling screening mechanism tilts to be arranged on feed track outlet and connects in the middle of grain mouth, radial gear and carrier chain between centers have gear drive, tremble screening mechanism and are connected with radial gear.Tremble screening mechanism and comprise sieve plate, removal of impurities plate and buffering reed, buffering reed downside is fixedly connected with frame, and upside is fixedly connected with sieve plate, and sieve plate inclination is arranged on and connects grain mouth upside, impurity discharging port is stretched out in upper side one end, and removal of impurities plate is arranged on sieve plate upper surface along the direction interval parallel with impurity removal port.
When equipment work, carry the power on chain rivet to be transmitted to and to tremble on screening mechanism through radial gear, owing to promoting and trembling the effect of screening mechanism bottom buffering reed the intermittence of radial gear, make sieve plate produce longitudinal judder reciprocating simultaneously, allow the confused flour beetle grain that contains on sieve plate advance to impurity discharging port great-jump-forward, material fully can be shaken loose, increase the chance of mixture through sieve aperture, overcome the defect of sieve pore blockade, simultaneously, arrange the assorted plates of getting rid of by interval more, the mixed material that outwards shakes out a segment distance can not moved down and new mixing of materials because moving back and forth again, in multistage dither process, through repeatedly trembling sieve, reach the effect of irreversible gradation sizing, can significantly reduce screening percentage of impurity and loss late.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
In figure: 1-frame, 2-radial gear, 3-trembles screening mechanism, the outlet of 4-feed track, 5-connects grain mouth, and 6-carries chain rivet, 7-sieve plate, 8-removal of impurities plate, 9-cushions reed, 10-impurity discharging port, 11-inclination angle, 12-cross blowing device, 13-row stone mouth.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, any change or the improvement done based on utility model training centre, all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model comprises frame 1 and radial gear 2, also comprise one can make that on-the-sieve material bounds forward tremble screening mechanism 3, trembling screening mechanism 3 tilts to be arranged on feed track outlet 4 and connects in the middle of grain mouth 5, to carry chain rivet 6 as line shaft, drive by radial gear 2, between radial gear 2 and conveying chain rivet 6, be provided with gear drive, tremble screening mechanism 3 and be connected with radial gear 2.The described screening mechanism 3 of trembling comprises sieve plate 7, removal of impurities plate 8 and front and back buffering reed 9, front and back buffering reed 9 downsides are fixedly connected with frame 1, upside is fixedly connected with sieve plate 7, sieve plate 7 inclinations are arranged on and connect grain mouth 5 upsides, impurity discharging port 10 is stretched out in upper side one end, and removal of impurities plate 8 is arranged on sieve plate 7 upper surfaces along the direction interval parallel with impurity removal port 10.When equipment work, carry the power on chain rivet 6 to be transmitted to and to tremble on screening mechanism 3 through radial gear 2, owing to promoting and trembling the effect of screening mechanism bottom buffering reed 9 intermittence of radial gear 2, make sieve plate produce longitudinal judder reciprocating simultaneously, allow the confused flour beetle grain great-jump-forward that contains on sieve plate advance to impurity discharging port 10, meanwhile, arrange the assorted plates 8 of getting rid of by interval more, realize the irreversible gradation sizing of grain.
Further, described feed track epimere downside is provided with cross blowing device 12, feed track exports 4 belows and is provided with row's stone mouth 13, fall into and tremble before screening mechanism 3 containing confused flour beetle grain, under the effect of cross blowing device 12, because rubble density ratio grain is greatly first in the row's of crashing into stone mouth 13, realize the separation of the foreign material that the proportions such as rubble are larger.
Preferential, when removal of impurities plate 8 is evenly arranged at sieve plate 7 upper surfaces, quantity is 4～10, and spacing is 50～500 millimeters, and sieve plate 7 and the inclination angle 11 of horizontal plane are 5～35 while spending, and screening effect of the present utility model is better.
For cereal or other crops of variable grain size, also applicable the utility model, only need adjust according to material characteristic spacing and the impurity discharging port height of sieve plate bore dia, removal of impurities plate.
