Small-sized seed air-screen separator

Technical field

The utility model relates to a kind of plant equipment of seed cleaning processing, utilizes selection by winnowing and screening principle that seed is cleaned processing.

Background technology

China's seed process technology is started late, and is blank substantially on seed processing experiment equipment research.At present, seed processing equipment commonly used in the seed processing industry mainly is large and medium-sized equipment, is applicable to that seed such as a fairly large number of cereal carries out the large batch of processing of cleaning.If be used for processing negligible amounts, be worth seeds such as higher vegetables, herbage, flowers, Chinese herbal medicine, can cause processing and clear difficulty, seed waste is more, and the small-sized seed air-screen separator that the utility model provides is specially adapted to the seed laboratory and carries out the processing of cleaning to seeds such as small lot vegetables, herbage, flowers of the research of seed processing experiment and seed processing enterprise.

The utility model content

The utility model provides a kind of small-sized seed air-screen separator, is mainly used in the processing problems of cleaning that solves all kinds of seed processing experiments researchs and small lot seed, use easy to operate, dependable performance.

The technical scheme of the small-sized seed air-screen separator of the utility model: aidr bells blast system is by blower fan 14 and front blowpipe 1, back air-suction duct 12, impurity collector 2, deduster 13, cleaning and sorting system 7 is formed, cleaning and sorting system top is contained near the screen(ing) machine top sieve, by circular pipe and impurity collector, front blowpipe, air inlet links to each other, during seed process top sieve, most of dust in the seed, light assorted, blighted grain is inhaled toward impurity collector by wind-force, near the cleaning and sorting system bottom is contained in and sieves under the screen(ing) machine, connect deduster, the blower fan exhaust outlet, when the seed of sieving machine sorting is discharged by main discharging opening, wherein residual dust, light mixing siphoned away by aidr bells blast system once more, through twice selection by winnowing, improve the seed oeverall quality; Screening system is made up of feed hopper 3, the dustpan 4 that connects material, vibrating regulator 5, charging dustpan 6, screen(ing) machine 8, transmission frame 9, screen(ing) machine drive motors 10, and feed hopper 3 side-lowers have a valve can regulate its aperture by screw rod, thereby changes charging rate; The dustpan 4 that connects material is equipped with vibrating regulator 5, by the vibrating regulator knob of rotation circuit console 11, can change the vibration frequency of the dustpan 4 that connects material, thereby changes the speed of charging; Screen(ing) machine 8 bottoms are linked to each other with an eccentric wheel by connecting rod, eccentric wheel is driven by drive motors, drive motors is equipped with a variable-frequency governor, change motor speed by changing ac frequency, to change the frequency of screen(ing) machine 8 reciprocally swingings, screen(ing) machine 8 biside plates are plank, and the hardwood glazing bar is equipped with in the inboard, are used to install, in, the sieve sheet of following three layers of different size, according to the seed appearance difference, can change the sieve sheet flexibly, charging dustpan 6 is contained in screen(ing) machine top, swings with screen(ing) machine, seed enters the screen(ing) machine top sieve by charging dustpan 6, the big assorted top sieve of staying is discharged by the waste material mouth, and all the other enter middle sieve, and sieve was discharged by discharging opening during large seed was stayed, seed less than middle sieve aperture flows into sieve down, after seed enters down sieve, underproof granule, little assorted by sieve aperture is by the discharge of waste material mouth down, the seed flow on the following sieve is to main discharge gate.

The beneficial effect of the small-sized seed air-screen separator of the utility model is: utilize selection by winnowing and screening principle, the seed of high added values such as small lot vegetables, flowers, herbage is cleaned processing, can improve the cleanliness of seed, simultaneously, be convenient to seed grading.This machine operation is easy to use, dependable performance.
