Preferably, said triangle is equilateral triangle with the length of side in 2 times in aperture.

Put into jumbo coin dropping bucket when the coin quilt is concentrated; When extremely suiting flow velocity through regulating rotary switch; Coin gets into the upper end of internal layer screening cylinder through targeting port and cylinder cap because the screening main body drives the screening main body through external force rotated axle simultaneously with certain angle tilt rolls and make coin glide with deadweight to roll; Described coin generally can be in the state like Fig. 3; When coin diameter during less than sieve coin hole coin can fall into down one deck screening through a number sieve coin hole, if do not fall into then can get into b or sieve the coin hole c number with the guidepost collision.As shown in Figure 4 when coin is overlapping, the spiral catch can the combing coin make it orderly by screening simultaneously the spiral catch can prevent that also coin from directly rolling out the mistake that screening area causes.What process internal layer screening trommelling finally flowed into internal layer coin output channel is the maximum coin of diameter.The coin that feeds sieve coin hole then gets into middle level screening cylinder with nexine coin output channel in the large diameter slightly coin entering of same principle; Minor coin then gets into outer screening cylinder; The coin of minor diameter gets into ectomesoderm coin output channel slightly; Minimum coin is then fallen into outer receiving trap, and finally gets into outer coin output channel, and this process has been accomplished coin separation function of the present invention.

The present invention is specially adapted to mass of coins and assembles occasion, like public transport company, financial department etc.The invention solves the classification in the coin sort process, also condition is provided for follow-up counting, packing.In practical application, the aid that can be used as manual separating coin uses separately, also can combine existing counting, packing technique to realize complete coin sort process.

Advantage of the present invention:

(1) adopts the distinctive multilayer design of drum-type separate mode to have continuity and continue big flow separation characteristics;

(2) has a plurality of coins screening function simultaneously;

(3) there are spiral catch and guidepost effect can effectively prevent to mix the coin phenomenon, improve separation efficiency;

(4) it is independent to can be used as the aid of manual separating coin, also can combine to count, packing technique realizes complete coin sort process applying flexible;

(5) cater to market demand design, simple and reasonable for structure, processing and fabricating is convenient, and cost is lower, helps market and popularizes.
