detailed description of the invention:

With reference to Figure of description, the utility model is described in further detail.

As shown in Figure 1: a kind of wheat seed selecting device, it is sieved by the one-level of sieve nest 2, and throw the second-order separation of grain device 4, the refining process of wheat seed can be completed efficiently, realize being separated completely of wheat seed and impurity particle, dust, mildew seed or handstone; Its concrete structure comprises support 6, and the top of support 6 is elasticly connected with sieve nest 2; The side of this sieve nest 2 is connected with vibrator 23; Concrete, be provided with spring 62 between described support 6 and sieve nest 2, described spring 62 is used for bearing sieve nest 2 and also participates in shaking link with the weight of vibrator 23;

Described sieve nest 2 is tilting and comprises upper and lower two-layer sieve, and the mesh size of upper strata sieve 21 is greater than the external diameter of wheat seed, can realize seed with slightly larger than the handstone of seed or being separated of plant residue, the sieve aperture of lower floor's sieve 22 is less than the external diameter of wheat seed, can realize seed and dust, being separated of impurity particle; Be provided with glove compartment 3 immediately below lower floor's sieve 22, one end of lower floor's sieve 22 is provided with the discharging opening 61 of discharging seed;

After sieve nest 2 sieves, for the benefit of conveying of screened seed; Be provided with in the downstream of discharging opening 61 and throw grain device 4; Throwing grain device 4 of the present utility model comprises active roll 42, driven running roller 45 and throws running roller 44, described active roll 42 and driven running roller 45 are arranged on pillar 41, described active roll 42 is by motor and drive driven running roller 45 to rotate by conveyer belt 43, describedly throw the upper middle side part that running roller 44 is arranged on conveyer belt 43, this throws running roller 44 and is pressed to by the conveyer belt 43 between active roll 42 and driven running roller 45 upper limb under driven running roller 45 upper limb horizontal plane; For improving the selected effect of wheat seed further, or the stone or impurity particle with wheat seed same volume size is distinguished, the downstream of this throwing grain device 4 is provided with collection container 5, and described collection container 5 comprises the heavy impurity case 51, smart tanker 52 and the light impurities case 53 that are linked in sequence and one-body molded; Preferably, throwing grain baffle plate 54 is fixedly connected with in one end of described light impurities case 53.According to the difference of the product phase quality of seed, by throwing power, the seed of heavier-weight or impurity particle just fall into the heavy impurity case 51 near throwing grain device 4, and relatively light impurity particle or mildew seed just fall into from the light impurities case 53 thrown away from grain device 4; The classification of this collection container arranges and effectively improves choicest quality further; In addition, the length dimension of described smart tanker 52 is greater than the size of heavy impurity case 51 or the size of light impurities case 53.

Vibration on Start-up device 23, sieve nest 2 vertical tremor, when wheat seed is after feed end 1 drops down onto sieve nest 2, seed drops to upper strata sieve 21 together with foreign material.By concussion, wherein seed falls into lower floor's sieve 22 with the foreign material being less than seed, and the seed fallen into lower floor's sieve 22 and foreign material, again by the vibrations of lower floor's sieve 22, the foreign material less than seed are fallen in glove compartment 3, so just achieve the primary vibration screening of wheat seed, improve operating efficiency, decrease labour intensity; With the vibrations of sieve nest 2, the wheat seed screened is rolled on throwing grain device 4 with the inclined-plane of lower floor's sieve 22, the band scooter 15M/S of conveyer belt 43, fall like this through screening wheat seed through conveyer belt 43 and throw between running roller 44 quickly through, and to dish out, according to the difference of the product phase quality of seed at a high speed from the upper end of driven voller wheel 45, further, the seed of same volume size is separated with foreign material, realizes the selected of wheat seed, improve the operating efficiency of automatic well-chosen.

Except technical characteristic described in description, be those skilled in the art known technology.
