Description
Technical field
Winnowing type seed purifier of the present invention belongs to seed processing equipment field.
Background technology
Wind screen type seed sorting machine is the capital equipment of seed and grain cleaning processing, and it mainly utilizes sieve by heavily assorted or large assorted removal the in seed and cereal, and the suction that utilizes blower fan to produce will gently be mixed or pathology seed is removed from good seed.If the patent No. is " 01263080.2 ", name is called the utility model patent of " Wind screen type seed sorting machine ", it adopts conventional in the industry two screen boxs four sieve structures, by ground floor sieve, removes large mixing, as the eyelets such as stone, soil block, fragment of brick, metal leak the thing of not going out; Assorted in removing by second layer sieve, than large assorted little and larger than seed foreign material; By the 3rd layer and the 4th sieve, the foreign material sieve less than seed removed, seed larger in the 3rd layer of sieve falls into the 4th layer of sieve from outlet, in company with less seed in the 4th layer of sieve, falls into discharging opening.The defect of this structure is that the larger seed in the 3rd layer of sieve can take a big chunk space of the 4th layer of sieve, makes the load-bearing of the 4th layer of sieve excessive, reduces efficiency of screen out and effect.
Summary of the invention
The object of the invention is to propose a kind of Winnowing type seed purifier, it improves for the weak point that in background technology, lower screen box structure exists, and opens up independently passage fall into discharging opening for large seedlet, improves utilization rate and the production efficiency of sieve.
The object of the present invention is achieved like this: Winnowing type seed purifier, comprise frame, feed system, screening system, screening drive unit, lower air chamber, sedimenting system, feed system is positioned at frame upper front part, and sedimenting system is positioned at rear portion, frame top, and lower air chamber is positioned at frame below; Between feed system and lower air chamber, be equiped with screening system, it is comprised of upper screen box and lower screen box, lower screen box is equiped with successively from top to bottom fall plate, macrospecies diversion component, macrospecies of lower upper sieve, microspecies and drops down plate and lower sieve, wherein fall plate and macrospecies of microspecies dropped down and between plate, is equiped with microspecies and drops down plate, and macrospecies diversion component and microspecies are dropped down and between plate, had the passage that leads to lower sieve for microspecies; Macrospecies diversion component comprises at least one group of deflector, mozzle, and mozzle drops down plate through microspecies and drops down plate with macrospecies and communicate.
Next-door neighbour's microspecies plate that falls also has a chute with slanting baffle, for stopping that the seedlet that microspecies fall on plate falls into macrospecies diversion component.
Deflector and mozzle can arrange many groups according to refiner size, adjacent two deflectors form the Delta Region of top sealing, relative two deflectors form the uncovered trapezoid area in top, and mozzle is positioned at trapezoid area, and the large seed falling into from lower top sieve sheet is imported to mozzle.
The lower upper sieve of next-door neighbour also has an additional chute, and described additional chute has a macrospecies passage, makes the large seed in lower upper sieve better fall into macrospecies diversion component along passage.
The fall chute of plate of next-door neighbour's microspecies is equiped with two slanting baffles, and two slanting baffles form macrospecies passages, make the large seed of lower upper sieve better fall into macrospecies diversion component along passage.
The passage of chute and additional chute is evenly equiped with reinforcement.
Beneficial effect of the present invention is: by the improvement to lower screen box, at lower screen box, partly introduce diversion component, form the separate passage of large seed and seedlet, improved seed screening effeciency, and greatly reducing the load of lower sieve, the quality of purification of seeds and output all can significantly improve.
