Working principle: when being convenient for the agricultural seed screening plant of feeding discharging using this, first by the device It is moved to applicable place, and connects power supply, with to be used；

It when carrying out feeding, turns fixing bolt 5 and the top of fixed plate 4 is removed, directly rotate fixed plate 4 and to fix The lifting platform 6 of the outer top surface of plate 4 is filled to horizontality, and the woven bag equipped with seed to be sieved is placed on to the upper top of lifting platform 6 The upper top surface of lifting platform 6 is moved to the position of the upper either flush with feed inlet 2 and front panel 3 by the rising of lifting platform 6 by face It sets, then opens woven bag, will be poured into sieve compartment 9 in engraved structure of the seed by feed inlet 2；

After seed enters 9 inside of sieve compartment, angularly it is arranged by the bull stick 7 of 9 inside push pipe of sieve compartment and its outside Obstruction plate 8 broken up, be unfavorable for being sieved to avoid seed directly in heaps fall, and bull stick 7 is under the impulse force of seed It is rotated, is spread out on oscillating screen plate 10 convenient for seed, since shaft 15, the first transmission belt 24 and agitating shaft 3003 are by type It number is driven for the teeter chamber 3001 of Y90S-2, drives fixed disk 16 to be rotated by the rotation of shaft 15, so that 17 interval of jacking block of appearance protrusion hits the top plate 12 above it, so that top plate 12 is risen, and top plate 12 is logical Cross spring 14 and mounting plate 13 and constitute stretching structure, consequently facilitating drive the oscillating screen plate 10 of 12 top integration of top plate connection into Row vibration, and the outer wall of oscillating screen plate 10 is fitted by the inner wall of close pad 11 and sieve compartment 9, consequently facilitating carrying out seed Screening, by once sieve by seed fallen leaves and other large-scale impurity leave, seed passes through the hollow out of oscillating screen plate 10 Structure falls,, can be to seed since the output end of air blower 18 is provided with the inside bottom righthand side of sieve compartment 9 in dropping process The dust inside having is blown, when in order to fall on seed on roller screen plate 19, under the incline structure by roller screen plate 19 Sliding, to flow on conveyer belt 22, dust is fallen in ash accumulating chamber 20 into the engraved structure for crossing roller screen plate 19；

Since conveyer belt 22 constitutes drive mechanism by the first transmission belt 24 by transfer roller 23, to pass through arc-shaped structure Conveyer belt 22 is transmitted seed, and the outside of conveyer belt 22 is uniformly provided with groove-like structure, avoids seed downslide, so as to It, will be in medicine-chest 26 by administration pump 27 in the teeter chamber 3001 that seed is reached to 22 top of conveyer belt, and in transmit process The silty drug in portion is sprayed on seed by the plate 28 that spreads pesticides, in order to the long-term storage of seed；

After seed is sent to 3001 inside of teeter chamber via conveyer belt 22, the agitating shaft 3003 under the drive of teeter chamber 3001 It is rotated, and is driven by belt wheel 3004 by the second transmission belt 3005 between 3003 monomer of agitating shaft, thus to seed Be stirred, in order to which drug is uniformly distributed in seed, it is agitated after seed opened up by correspondence below agitating shaft 3003 Discharge port 31 be flowed into the corresponding collecting bag 33 in lower section, and collecting bag 33 by limited block 3202 and 31 outer wall of discharge port it Between engaging be fixed, telescopic rod 3201 elongation effect under limited block 3202 and the outer wall of discharge port 31 are connect, And by the outer top surface concave-convex surface structure of limited block 3202, the landing of collecting bag 33 can be avoided, and then convenient for after to screening Seed be collected storage, here it is this be convenient for feeding discharging agricultural seed screening plant it is entire worked Journey, the content being not described in detail in this specification belong to the prior art well known to professional and technical personnel in the field.

The standardized element that the present invention uses can commercially, and shaped piece is according to specification and attached drawing note Load can carry out customized, and the specific connection type of each part is all made of in the prior art mature bolt, rivet, welding etc. Conventional means, mechanical, part and equipment are all made of in the prior art, conventional model, in addition circuit connection uses the prior art Middle conventional connection type, this will not be detailed here.
