Description
Technical field
The utility model relates to the selected classifying screen of a kind of rice.Specifically, be a kind of being used for hulled rice to be separated into the crack rice device of whole rice, big broken rice and small brokens of content of difference.
Background technology
White rice grader is one of capital equipment of rice processing rice aftertreatment technology, is used for rice is divided into difference crack rice whole rice, big broken rice and the small brokens of content.At present, 4 vaulting pole formulas, the white rice grader of joining the punching compass screen surface are one of principal modes of white rice grader kind equipment, are three layers of compass screen surface, from top to bottom, obtain four kinds of products successively: special rice, general rice, big broken rice, small brokens, three layers of compass screen surface sieving area are equal substantially.Above-mentioned rice sieve, the usable floor area of various products is equal substantially.And in fact, general rice has more sieving area with the separation requirement of cracking rice, the mis-arrange of this sieving area, and it is all higher to contain head rice yield during the result causes general rice and cracks rice.
Summary of the invention
The purpose of this utility model is to provide a kind of rice selected classifying screen, to improve general rice and the separating effect of cracking rice.
In order to achieve the above object, the technical solution of the utility model is following design:
A kind of white rice grader, comprise the space, be installed on sieve plate within the casing, drop down plate, sieve plate, drop down corresponding charging aperture, discharging opening are arranged on the plate, it is characterized in that: the ground floor of accepting the screenings of ground floor sieve plate drops down plate between ground floor sieve plate and second layer sieve plate, the oversize outlet of ground floor sieve plate is communicated with special rice discharging opening, and the discharging opening that ground floor drops down plate is connected with the charging aperture of second layer sieve plate; Between second layer sieve plate and the 3rd layer of sieve plate, being distributed with the second layer that is used to accept second layer sieve plate screenings successively drops down plate, is used to accept the 3rd layer of second layer sieve plate oversize and drops down plate, the discharging opening that the second layer drops down plate is connected with the charging aperture of the 4th layer of sieve plate, the 3rd layer of discharging opening that drops down plate is connected with the charging aperture of the 3rd layer of sieve plate, and the oversize outlet of the 3rd layer of sieve plate is communicated with general rice discharging opening; Between the 3rd layer of sieve plate and the 4th layer of sieve plate, be distributed with the 4th layer of being used to accept the 3rd layer of sieve plate oversize and drop down plate, the oversize discharging opening of the 4th layer of sieve plate is communicated with the big broken rice discharging opening; Be distributed with the small brokens bearing plate under the 4th layer of sieve plate, the small brokens bearing plate is communicated with the small brokens discharging opening.
A kind of white rice grader is characterized in that: the discharging opening that the second layer drops down plate is communicated with by being positioned at the outer aggregate pipe of casing with the charging aperture of the 4th layer of sieve plate.
In the technical solution of the utility model, in the sieve nest that has only four layers of compass screen surface configuration, continuous two-layer compass screen surface is set strengthens general rice and separating of cracking rice with the form of relative series connection.Like this, in sieve nest of the present utility model, the sieve diameter of ground floor compass screen surface is used to choose special rice greater than the second layer, the 3rd layer of compass screen surface; Second, third layer compass screen surface chosen general rice with the form of relative series connection; The 4th layer of compass screen surface is used to crack rice and the separating of small brokens.In order to make structure simpler, flow scheme design is more reasonable, and the approach that the screenings of second layer compass screen surface arrives the 4th layer of compass screen surface is arranged on the outer aggregate pipe of sieve nest; The approach of one deck compass screen surface was arranged on the plate that drops down in the sieve nest under the screenings of other each layer compass screen surface arrived; In order to make the utility model more can adapt to the requirement of different cultivars rice classification, also the stepless time adjustment device can be set, this device has been fixed on the support.
The beneficial effects of the utility model are: wide accommodation, and the effectiveness of classification height, the broken ratio of extra grade rice and the middle whole rice including rate of cracking rice are all below 3%, and general rice contains broken below 10%.
