Description

TECHNICAL FIELD

[0001] The utility model discloses a kind of five-gear wind force seed dividers, and it is suitable for fine sorting of seeds of different weight and volume. BACKGROUND

[0002] In the seed processing process, the classification screening of seeds is the key link to ensure the quality of sowing. The traditional screening equipment relies on gravity screening or mechanical screening, which has the following disadvantages: the sorting accuracy of light seeds is insufficient, and it is easily affected by the shape of seeds; the classification range is small, and it is difficult to meet the multi-specification demand of high-end seed commercial production; the energy consumption is high, and the equipment structure is complex, with high maintenance cost. Although the existing wind force sorting equipment can realize classification by utilizing the difference between seed gravity and air resistance, it generally has problems such as inaccurate classification region division and easy clogging of the collecting device. The utility model optimizes the air flow path and the layout of the classification box to provide a five-grade wind force seed divider with fine sorting and low energy consumption. SUMMARY

[0003] The utility model provides a kind of five-gear wind force seed divider, provides a kind of wind force seed divider that can realize five-grade accurate classification, compact structure and high sorting efficiency, solves the problem of insufficient classification accuracy and single range of existing equipment.

[0004] The utility model discloses a kind of five-gear wind force seed divider by the technical scheme that technical problems are solved by the utility model are as follows: a five-gear wind force seed divider is composed of casing, fan device, seed injection box, seed guide baffle, first-level seed classification box, second-level seed classification box, third-level seed classification box, fourth-level seed classification box and fifth-level seed classification box. The side of casing is provided with fan device;Seed injection box is installed on the upper side of casing close to fan device end;Seed guide baffle is installed on the lower side of seed injection box;Casing bottom is sequentially installed first-level seed classification box, second-level seed classification box, third-level seed classification box, fourth-level seed classification box;Fifth-level seed classification box is set in the end of casing away from fan device.

[0005] Working principle: the seed to be sorted falls to guide baffle from injection box, and enters casing sorting cavity after being dispersed by inclined plate surface. The horizontal air flow generated by fan device flows from fan end to fifth classification box direction, forming a gradient air flow field from strong to weak. Seeds are affected by gravity and air resistance in air flow, and heavy seeds fall into first classification box first, and second classification box for secondary heavy seeds, and so on, and the smallest and lightest seeds float to the end of fifth classification box with air flow, to realize five-grade classification.

[0006] The five-grade wind force seed sorter has the advantages of five-grade fine selection, can accurately divide the seeds into five grades according to weight / volume through the layout design of gradient air flow field and grading box, meets different seeding requirements, is high in efficiency and energy saving, can greatly reduce energy consumption compared with traditional mechanical screening, is high in structure optimization, the angle of the guide baffle can be adjusted to adapt to the selection requirements of different varieties of seeds, is convenient to clean and maintain due to the detachable design of the grading box, is low in damage rate, avoids seed damage due to the non-mechanical contact type selection, and is especially suitable for kernel fullness selection.
