because the middle iron block 2031 is located between the upper iron block 2011 and the lower magnet 2053, when the lower magnet 2053 approaches the elastic cloth 201, the upper iron block 2011 and the middle iron block 2031 can be magnetically adsorbed by the lower magnet 2053, when the lower magnet 2053 approaches the elastic cloth 201, the elastic cloth 201 and the elastic net 203 are pulled to deform, and after the lower magnet 2053 moves for a distance, the upper iron block 2011 and the elastic cloth 201 firstly reset to screen hybrids to be removed, and the middle iron block 2031 is reset again;
when the middle iron block 2031 is reset, the vibrating elastic cloth 201 is knocked, so that dust remained by the elastic cloth 201 during seed screening can be vibrated, the dust falls off, the dust is prevented from accumulating in gaps of the elastic cloth 201 to influence the elasticity of the elastic cloth 201, and the seed screening effect of the elastic cloth 201 is further improved;
step three: when the elastic cloth 201 is reset, the seeds to be decontaminated fall on the elastic cloth 201 from top to bottom, and the elastic cloth 201 impacts with the seeds to be decontaminated, so that the seeds to be decontaminated fly towards the baffle 3001, wherein large-mass objects in the seeds to be decontaminated fly over the baffle 3001 to enter the upper end of the upper filter plate 3, small-mass objects in the seeds to be decontaminated fly over the baffle 3001 and cannot fall from the lower end of the baffle 3001;
the large-mass objects roll on the inclined upper filter plate 3, the large-mass objects which pass over the baffle 3001 comprise full-grain paeonia lactiflora seeds and paeonia lactiflora shells, the density of the paeonia lactiflora shells is lower than that of the paeonia lactiflora seeds, the grain size of the paeonia lactiflora shells is larger than that of the paeonia lactiflora seeds, the paeonia lactiflora seeds are filtered and collected into the second collecting box 102 through the upper filter plate 3, and the paeonia lactiflora shells fall into the first collecting box 101 along the upper filter plate 3;
the small-mass object falls from the lower end of the baffle 3001, the small-mass object comprises part of peony seeds, crushed peony leaves and part of other impurities with full particles but small particle size, during the flying process of the small-mass object, the peony seeds are firstly attached to the baffle 3001 under the influence of air resistance, the particles are full, the resilience force is high when the small-mass object is impacted with the baffle 3001, the flying speed of other impurities is slow, the resilience force is low when the small-mass object is impacted with the baffle 3001, namely, when the small-mass object is rebound, the peony seeds with high resilience force are subjected to the influence of gas flow and continuously fall into the third collecting box 103, and when the other impurities with low resilience force are subjected to the influence of gas flow and are sucked and collected by the suction port 105;
when the dried soil is attached to the elastic cloth 201, the dried soil is elastically impacted by the elastic cloth 201, so that the soil is dispersed into dust and can be sucked and collected by the suction ports 105; it should be noted that a small amount of dust is attached to the peony seeds, and the peony seeds are simply washed at the moment, so that the waste of water resources is reduced;
and when the sliding frame 207 slides reciprocally, the two groups of elastic fabrics 201 can deform reciprocally to screen the seeds to be screened, so that the seeds to be screened are effectively prevented from being directly piled on the elastic fabrics 201, and the impurities in the seeds and the impact of the elastic fabrics 201 are facilitated;
specifically, when the lower magnet 2053 pulls the elastic cloth 201 to move downwards to deform, the air in the guide cylinder 205 enters one of the connecting covers 407 through the lower connecting pipe 4071, so that the air flows to drive the fan blade 406 to rotate, and further the threaded rod 405 rotates, the position of the control block 403 is adjusted, the discharge port 404 closes the discharge port 402 on the side, opens the discharge port 402 on the other side, seeds fall from the discharge port 402 on the other side, and then when the lower magnet 2053 is separated from the upper iron 2011, the seeds falling before fall on the elastic cloth 201 and impact with the elastic cloth 201;
when the other lower magnet 2053 moves downward, the control block 403 is repeatedly adjusted, and the gas blown out from the upper connection pipe 4072 can blow the movement of the mass material on the upper filter plate 3, thereby preventing the mass material from being caught on the V-shaped guide plate 301.
According to the invention, through the elastic cloth 201, the seeds to be decontaminated can be screened according to different mass sizes, meanwhile, objects with large mass can be filtered to screen out large and full peony seeds, objects with small mass can be screened out according to rebound speed during impact to screen out small and full peony seeds, soil in impurities is dried and then is impacted into dust to be collected, so that the screening effect on the peony seeds is good, and the screening efficiency is high.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
