Abstract
The utility model relates to a grading and screening machine used for rice class grains (white rice) or other types of grains, particularly a Dual-feeding grading and screening machine comprising a material-separating machine and a separating screen. The utility model is characterized in that the material-separating machine is provided with two discharge holes; the separating screen is provided with two layers of whole particle screening screen surfaces of same mesh size and two layers of broken particle screening surfaces of same mesh size; the two discharge holes of the material-separating machine are respectively aligned to two layers of whole particle screening screen surfaces, and the lower part of two layers of whole particle screening screen surfaces are respectively provided with a material return plate. The utility model causes the grains to be separated to enter the whole rice screening surface in the way of split flow through one material-separating mechanism to increase the effective sifting surface of the grains. The double-layer whole rice separation screening surface is utilized to increase the probability that the broken rice contacts the screen surface, thereby, majority of whole rice can be effectively separated rapidly; without increasing the occupation area and use cost of the device, the yield of the device can be increased in multiples.
Description
Technical field
The utility model relates to a kind of rice class cereal (rice) or other types cereal sizing screening machine of being used for, and is a kind of pair of charging sizing screening machine specifically.
Technical background
No matter which kind of form traditional white rice grader it be, all be according to need carry out the rice after the processing whole rice, big broken rice, in crack rice and four kinds of classifications of small brokens, and correspondingly be provided with two layers or three layers of compass screen surface, its process route chart is seen accompanying drawing 1.For making white rice grader most for separating through the ground floor compass screen surface the material of whole rice from accounting for cracking rice, must guarantee to crack rice can maximum of probability ground contact compass screen surface.Under the mass flow prerequisite identical with flow velocity, compass screen surface is wide more like this, and the material bed thickness of stream on compass screen surface just can be thin more, and the probability of the contact compass screen surface of cracking rice is just big more, and the effect of screening is just good more.And the defective of traditional rice sieve exactly is: make good like that the effect of screening supposes as described above, the compass screen surface of just must widening or extend is with the increase sifting surface.So not only strengthen and install and use floor space, and output and screening effect are all and not really desirable.Therefore, invent a kind of floor space is little, screening effect good, output is big sizing screening machine is the technical problem that the technical staff of the industry is expected to solve always.
The cereal-granules size is carried out sieving and grading.It has a feeding distribution mechanism and double-deck bulky grain (promptly whole grain) screening compass screen surface.Can be that oarse-grained cereal carries out effective rapid screening classification to accounting for the overwhelming majority.
Summary of the invention
Technical problem to be solved in the utility model is: the defective at existing product exists, a kind of pair of charging sizing screening machine is provided, and it can not increase under occupation area of equipment and the use cost situation, increases the output of equipment doublely.
The technical solution of the utility model is achieved in that it comprises a depiler and bolter, it is characterized in that: depiler has two discharging openings, bolter is provided with identical whole grain screening compass screen surface of two layer screen hole size and particle screening face, two discharging openings of depiler are aimed at two-layer whole grain screening compass screen surface respectively, under the two-layer whole grain screening face feed back plate are housed all; The particle screening face of bolter also has two-layer, two-layer slot size difference; Depiler comprises a feed hopper, and adjustable track is housed on the feed hopper, is fixed with the adjusting pressing plate on the adjustable track, regulates the oblique buffer board that is equipped with on the pressing plate, and adjustable track is connected with adjusting screw(rod) by thread bush, and an end of adjusting screw(rod) is equipped with handle.
The utility model makes cereal shunting to be separated enter whole rice huller screen face by a feeding distribution mechanism, to reduce the thickness of whole rice huller screen precoat, increases the effective sifting surface of cereal.Adopt double-deck whole rice separation compass screen surface to crack rice and contact the compass screen surface probability, thereby can fast and effeciently isolate the whole rice that accounts for the overwhelming majority,, can increase the output of equipment doublely not increasing under occupation area of equipment and the use cost situation with increase.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 2, the utility model comprises a depiler 1 and bolter 2, depiler 1 has two discharging openings 3 and 4, bolter 2 is provided with the identical whole grain screening compass screen surface 5 and 6 of two layer screen hole size, and particle screening face 7 and 8, two discharging openings 3 of depiler 1 and 4 are aimed at two-layer whole grain screening compass screen surface 5 and 6 respectively, two-layer whole grain screening face 5 and 6 times feed back plate 9 and 10 are housed all; Between the two-layer particle screening face of bolter 2 feed back plate 11 is housed, the slot size difference of two-layer particle screening face is equipped with the plate 12 that gathers materials below the bottom particle screening face 8; Depiler 1 comprises a feed hopper 13, adjustable track 14 is housed on the feed hopper 13, is fixed with on the adjustable track 14 and regulates pressing plate 15, regulate the oblique buffer board 16 that is equipped with on the pressing plate 15, adjustable track 14 is connected with adjusting screw(rod) 18 by thread bush 17, and an end of adjusting screw(rod) 18 is equipped with handle 19.
During work, material was divided into two fens through behind the depiler 1, entered the ground floor whole grain classification compass screen surface 5 and the whole grain of the second layer classification compass screen surface 6 of bolter respectively.Because material is through disperseing, the material bed thickness that enters whole grain classification compass screen surface is compared has only the classifying screen of the whole grain of one deck classification compass screen surface to approach, under sieve nest motion, crack rice correspondingly easier contact and see through compass screen surface of large, medium and small in the material enters big particle classification compass screen surface 11 behind feed back plate 9 and 10.Being equivalent to two classifying screens like this works at the same time.Because account for the overall material overwhelming majority's whole grain in extraction after, the large, medium and small particle amount that enters big particle classification compass screen surface 7 is less, at the particle classification compass screen surface that has only one deck also each self-separation well.The only a few comminutions separates through 12 particle screening faces.At last, through the whole grain separated and large, medium and small particle through separately tapping channel outflow sieve nest.By handle 19 can adjustable track 14 the position, thereby the position and the angle of regulating buffer board 16 can be regulated the size and the pressure of inlet amount, and material is evenly distributed.
