Abstract
The utility model discloses a distribution device of a reciprocating or vibrating type screen box. The device is arranged in sequence, from top to bottom, in one-stage and two-stage sieves in the box, and a feed inlet and outlet of the box. The distribution device is arranged below the one-stage sieve at the feed inlet end and is used for distributing materials to the sieve. The distribution device is a strip-like groove arranged below the one-stage sieve equally at intervals, wherein the upper end closes to the bottom of the one-two stage sieve and the lower end is parallel to or slightly extends out of the end part of the one-stage and two-stage sieves. Material receiving cavities are arranged below the one-two stage and two-two stage sieves, and the material receiving cavity of the one-two stage sieve is provided with material discharge grooves from the middle to both sides in the width direction, respectively. The end part of the material discharge groove is communicated with a vertical-type passage on the outer side of the box, and is further communicated with the material receiving cavity of the two-two stage sieve through the vertical passage so that small impurities after sieve purification are discharged from an impurity port. The production efficiency of the sieve with the same area is improved by one fold. The utility model has the advantages of high purification efficiency, low production cost as well as convenient installation and use.
Description
Technical field
The utility model relates to agricultural mechanical field, is specifically related to before the cereal warehouse entry and the screening type knot screen of purification of seeds.
Background technology
Cereal after the results before warehouse entry or purification of seeds all to carry out removal of impurities with knot screen; With regard to screening type; Knot screen is generally the screen box structure, and inside is provided with the sieve sheet of multilayer different meshes, and cereal gets into screen box from charging aperture; Through upper sieve sheet, middle level sieve sheet, lower screen sheet, flow process is a tandem successively; Big assorted by the upper sieve isolation, little mixing separated from lower screen; What sieved in the middle level is up and down the finished product of two different brackets, and the effect in visible middle level is exactly classification; For before the cereal warehouse entry or for the purification of seeds, what is exactly " in the middle of going to stay for a short time greatly ", and the middle level sieve just seems unnecessary, and effect how to bring into play the middle level sieve is exactly the main points of present technique innovation.Be about to the middle level sieve and change into the same action of lower screen, through installing feeding-distribution device additional, making the middle level sieve is parallelly connected flow process with lower screen, is not enlarging the screen box volume, is not increasing to make under the situation of sieve sheet quantity and remove little beans flour noodle and amass and double like this.In the practice, removing big assorted efficient with area sieve sheet is to remove more than a times of little assorted efficient, so, to remove little assorted sieve sheet and double, the operating efficiency of whole screen box also is doubled with regard to actual.This screen box has that dust removal rate height, cost of manufacture are low, installation, advantage easy to use.
Summary of the invention
The technical problem that the utility model will solve provides the feeding-distribution device of a kind of reciprocating motion or oscillatory type screen box, sieve sheet of the same area, and production efficiency doubles.
The utility model is realized through following technical scheme:
The feeding-distribution device of a kind of reciprocating motion or oscillatory type screen box; Comprise the one-level, the secondary sieve sheet that are set in turn in from top to bottom in the casing; And the charging aperture, product outlet, big assorted outlet, the little assorted outlet that are arranged at casing; Characteristics are that the one-level sieve sheet below that is positioned at feed inlet end is provided with feeding-distribution device, and material is distributed to first secondary sieve sheet and second secondary sieve sheet.
The further improvement project of the utility model is, feeding-distribution device is the groove of strip, five equilibrium, is arranged at intervals at one-level sieve sheet below.
The utility model further improvement project is, the feeding-distribution device notch upwards, be the skewed one-level sieve sheet below that is arranged at, its upper end is near one-level sieve sheet bottom surface, the lower end is concordant with first secondary sieve sheet end or slightly stretch out first secondary and sieve the sheet end.
The utility model further improvement project is; First secondary sieve sheet and second secondary sieve sheet below are provided with the chamber that connects material; The chamber that connects material of first secondary sieve sheet is respectively equipped with discharge groove from the centre to both sides in width; Discharge groove end and the vertical channel connection that is located at the casing outside are communicated with the chamber that connects material of second secondary sieve sheet through this vertical passage again, make little assorted after first secondary sieve sheet and the removal of impurities of second secondary sieve sheet concentrate discharge from an impurity outlet.
The utility model compared with prior art has following obvious advantage:
One, the utility model is owing to be provided with feeding-distribution device below one-level sieve sheet; Material etc. is given first secondary sieve sheet and second secondary sieve sheet; That is to say has two Zhang Gongs to make the identical sieve of content in a casing; Therefore, can significantly improve the production efficiency of screening not enlarging the screen box volume, not increasing under the situation of sieve sheet quantity.
Two, the utlity model has that dust removal rate height, cost of manufacture are low, installation, advantage easy to use.
Description of drawings
Fig. 1 is the vertical cross-sectional schematic of the utility model B-B.
Fig. 2 is Figure 1A-A cross-sectional schematic.
The specific embodiment
Like Fig. 1, shown in 2, the utility model comprises one-level sieve sheet 2, the secondary sieve sheet 3,4 that is set in turn in from top to bottom in the casing 1, and is arranged at the charging aperture 5 of casing 1, big mix outlet 7, product outlet 8, little assorted outlet 10, also comprises feeding device 14.
Still like Fig. 1, shown in 2, one-level sieve sheet 2 belows that are positioned at charging aperture 5 these ends are provided with feeding-distribution device 6, material is distributed to first secondary sieve sheet 3 sieve sheet 4 with second secondary.Said feeding-distribution device 6 is the groove of strip, five equilibrium, is arranged at intervals at one-level sieve sheet below.Feeding-distribution device 6 notches make progress, are the skewed setting of 20 ~ 35 degree, and the upper end of feeding-distribution device 6 is near one-level sieve sheet 2 bottom surfaces, and the end of first secondary sieve sheet 3 is slightly stretched out in the lower end.
Still like Fig. 1, shown in 2; First secondary sieve sheet 3 and second secondary sieve sheet, 4 belows are respectively equipped with the chamber 11,12 that connects material; The chamber 11 that connects material of first secondary sieve sheet 3 is provided with discharge groove 9 in the width both sides; The vertical passage 13 in connection casing 1 outside, end of discharge groove 9 is communicated with the chamber 12 that connects material of second secondary sieve sheet 4 through said vertical passage 13 again, makes little the mixing from an impurity outlet 10 concentrated discharges after first secondary sieve sheet 3 and second secondary sieve sheet 4 removal of impurities.
