Description

Technical Field

[0001] This utility model relates to the technical field of seed screeners, and more particularly to a seed screener. Background Technology

[0002] Seeds are the reproductive organs of plants, typically composed of an embryo, endosperm, and seed coat. Seeds are the primary means of plant reproduction; by sowing seeds, new plants can be produced. During harvesting, storage, and transportation, insect eggs may become contaminated with seeds, and some seeds may be eaten by insects during storage, leaving only shell fragments. Therefore, in agricultural production, seeds need to be screened to remove these impurities and improve seed purity.

[0003] Chinese patent publication number CN218049002U discloses an agricultural seed screener, relating to the field of seed screening technology. This invention includes a housing with a feed trough fixedly connected to the top. The bottom of the inner surface of the feed trough has an inclined surface, and a feed inlet is fixedly connected to a corner of the bottom of the inner surface of the feed trough. The flow direction of the inclined surface points towards the feed inlet. An inclined plate is fixedly connected inside the housing, and several fans are fixedly connected to the housing on the downward-sloping side of the inclined plate, arranged linearly along the edge of the inclined plate. This invention uses the inclined surface inside the feed trough to automatically allow seeds to fall onto the surface of the inclined plate. The fans blow air onto the seeds sliding on the inclined plate, separating plump seeds from empty seeds eaten by insects and dust impurities, thus completing the seed screening process and retaining only high-quality seeds, improving the success rate of seed growth after sowing.

[0029] Working principle: During use, the screw 14 is rotated by the knob 15, which drives the door 16 to move along the guide rod 17 toward the screen box 3 until it closes with the screen box 3. The seeds to be screened are added into the screen box 3 through the feed trough 5. The first motor 13 is started, which drives the second rotating shaft 11 and several driving bevel gears 12 to rotate, which in turn drives the driven bevel gears 9 meshing with the driving bevel gears 12 to rotate synchronously. Then, several first rotating shafts 7 rotate synchronously. The stirring plate 8 is used to stir and disperse the added seeds to prevent them from clumping together. Clumped seeds can easily trap impurities. Stirring and dispersing clumped seeds can improve the screening effect and efficiency. Impurities such as insect eggs and debris contained in the seeds fall to the bottom through the screen holes 6. In the waste box 30, the second motor 29 is started, which drives the third rotating shaft 27 and cam 28 to rotate. Through the rotation of cam 28, the support frame 21 is pushed up and down to reciprocate by its contour, which in turn drives the front end of the sieve box 3 to swing up and down around the hinge with the side frame 2. In conjunction with the stirring plate 8, the seed screening is accelerated. During the screening process, a large amount of dust and floating matter are easily generated. The air pump 33 is started to suck the dust and floating matter in the sieve box 3 into the dust collection box 32 through the connecting pipe 34, so as to prevent the dust and floating matter from falling back into the seed space and improve the screening effect. After screening, the knob 15 is turned in the opposite direction to open the box door 16. The seeds are discharged into the recycling box 31 through the opening of the sieve box 3 and in conjunction with the up and down reciprocating swing of the front end of the sieve box 3.
