Below in conjunction with above-mentioned accompanying drawing embodiment the utility model is remake and to describe in further detail.
Shown in Fig. 1～5, the rice recleaner screen of flatting turn comprises the actuating unit that is located in the frame (16) and selected (classification) mechanism that is located in the sieve nest (2), also comprise the feed hopper (1) that is located at the sieve nest top, the discharge bucket of sieve nest right-hand member and the receiving hopper of frame lower (15), feed hopper and discharge bucket turn round with sieve nest.
Actuating unit is a prior art, comprise and be fixed on the motor (17) that can shake adjusting position in the frame (16), the motor outputting power is given the speed adjusting gear (19) that is fixed on motor shaft end, this speed adjusting gear is handled speed governing by speed governing strainer (20), the gap bridge transmission mechanism (18) that links to each other with the speed adjusting gear drive belt, and be arranged at frame top be used to support sieve nest and drive sieve nest and sieve nest in the sieve lattice, drop down 3 groups of eccentvic rotation mechanism compositions such as (21) that plate is done plane rotation motion.
Selected (classification) mechanism comprise be located in the sieve nest (2) with 1.2 degree inclination angles and have sieve aperture ground floor sieve lattice (3), second layer sieve lattice (5), go up double-deck combination sieve lattice (8), double-deck combination sieve lattice (9) down, the sieve lattice have the opposite water conservancy diversion in inclination angle and drop down plate, promptly divide into the mixture water conservancy diversion at ground floor sieve lattice (3) and drop down plate (4); Second layer sieve lattice (5) are divided into double-deck water conservancy diversion and are dropped down plate (6); Set double-deck water conservancy diversion under the last double-deck combination sieve lattice (8) (promptly the 3rd, the 4th layer) and drop down plate (7), following double-deck combination sieve lattice (9) (being layer 5, layer 6) are divided into the small brokens water conservancy diversion and are dropped down plate (10).
Adopting the version of double-deck combination sieve lattice is in order to reduce the sieve nest height.Individual layer and double-deck combination sieve lattice all have a screen frame (23), this screen frame is divided into frame structure mutually by tensioning frame (25), panel (22) is fixed as one with screen frame, the framework upper strata fixedly has the separation sieve plate (24) of densely covered sieve aperture, lower floor fixedly has the holder net (27) of densely covered grid hole, separate between sieve plate and the holder net being provided with cleaning ball (26), the purpose that the cleaning ball of rubber system is set is to make it to produce collision mutually in motion process, thereby removes the rice material that embeds in the sieve aperture.The aperture of holder net grid hole should help the discharge of screenings greater than the sieve aperture that separates sieve plate.
Separation sieve plate (24) in the sieve lattice is the punching sieve plate, its sieve diameter is respectively: ground floor sieve lattice (3) are 3.7 millimeters of φ 3.5～φ, it is 3.6 millimeters of φ 2.8～φ that second layer sieve lattice (5) and the 3rd layer of sieve lattice are promptly gone up double-deck upper strata of making up sieve lattice (8), it is 2.6 millimeters of φ 2.4～φ that the 4th layer of sieve lattice are promptly gone up double-deck lower floor and the promptly double-deck down upper strata of making up sieve lattice (9) of layer 5 sieve lattice of making up sieve lattice (8), and the promptly double-deck down lower floor that makes up sieve lattice (9) of layer 6 sieve lattice is 2.0 millimeters of φ.
Upper and lower double-deck water conservancy diversion drops down plate (6), (7) comprise that the upper strata water conservancy diversion drops down plate (28) and lower floor's water conservancy diversion drops down plate (29), middle is separated by with contour axle sleeve (31), and being fixed with one by fastening connection piece (30) then forms double-deck water conservancy diversion and drop down plate.
Discharge bucket from top to bottom for whole rice discharge bucket (11), big broken rice discharge bucket (12), in crack rice discharge bucket (13) and small brokens discharge bucket (14).
What the utility model raw material rice got off from layer 6 sieve diagrid is the mixture of small brokens and chaff powder, when needs further separate small brokens and chaff powder, can with the below that the small brokens water conservancy diversion drops down plate (10) a single-deck screen lattice (not shown) that separates the chaff powder be set again at following double-deck combination sieve lattice (9), the corresponding chaff powder water conservancy diversion that is provided with below these sieve lattice drops down plate and chaff powder discharge bucket (not shown).
When using the utility model, starter motor (17) at first drives gap bridge transmission mechanism (18) by the speed adjusting gear (19) of motor shaft end by drive belt, drives eccentvic rotation mechanism (21) by drive belt again and makes sieve nest (2) do the plane rotation motion.The raw material rice enters in the sieve nest through feed hopper (1) refining, contact with the sieve plate (24) that separates with certain inclination angle, a certain size sieve aperture, produce relative motion, form the track of zigzag shape, advance to discharge end by feed end, in motion process, the raw material rice forms automatic classification, the whole rice of bulky grain floats on the granule upper strata of cracking rice becomes oversize, and granule is cracked rice to contact with compass screen surface and pierced into sieve aperture and become screenings, reaches the purpose of rice selected (classification) thus.
Its technological process is referring to Fig. 5 (dropping down plate with 6 layers of sieve lattice and 6 layers of water conservancy diversion is example): the raw material rice enters ground floor sieve lattice (3), through the screening oversize is whole rice, sieve down mixture to drop down plate through the ground floor water conservancy diversion be that the mixture water conservancy diversion drops down plate (4) and enters second layer sieve lattice (5), three layers of underflows to the sieve lattice that this oversize drops down plate (6) through last double-deck water conservancy diversion are promptly gone up the upper strata that double-deck combination sieves lattice (8) and are screened once more, its oversize is whole rice, and oversize (whole rice) merging of sieving lattice with ground floor enters whole rice discharge bucket (11); The screenings of second layer sieve lattice (5) flows into the lower floor that the 4th layer of sieve lattice are promptly gone up double-deck combination sieve lattice (8) through the upper strata that last double-deck water conservancy diversion drops down plate (6), simultaneously the 3rd layer of sieve lattice screenings of promptly going up the upper strata of double-deck combination sieve lattice (8) the 4th layer of sieve of people lattice that also fall are promptly gone up the double-deck lower floor of sieving lattice (8) that makes up, together after screening, its oversize through the lower floor that double-deck water conservancy diversion down drops down plate (7) flow into layer 5 sieve lattice promptly down the upper strata of double-deck combination sieve lattice (9) through programmed screening, this oversize is a big broken rice then, enters big broken rice discharge bucket (12); The screenings that the 4th layer of sieve lattice are promptly gone up double-deck combination sieve lattice (8) flows into the lower floor that lattice (9) are sieved in the promptly double-deck down combination of layer 6 sieve lattice through the upper strata that double-deck water conservancy diversion down drops down plate (7), the while layer 5 sieve lattice screenings that the upper strata of lattice (9) is sieved in double-deck combination promptly also falls into the layer 6 sieve lattice lower floor that lattice (9) are sieved in double-deck combination promptly and screens together, this oversize is cracked rice in then being, the discharge bucket (13) of cracking rice in entering; Screenings drops down plate (10) through the small brokens water conservancy diversion and enters small brokens discharge bucket (14).More than four kinds of materials flow into four basins that connect material of receiving hopper (15) respectively, four discharging openings through the receiving hopper bottom enter the workshop material pipe.
