Description

A kind of efficient cleaner of low damage of particulate crop

Technical field

The utility model relates to clean agricultural equipment field, specifically a kind of low damage of particulate crop is efficiently cleaned Machine.

Background technique

The existing relatively common technology of cleaning specifically includes that blower-vibrating screen cleaning and sorting system, blower-material outer-flowing type Drum sieve cleaning and sorting system, blower-material in-flow drum sieve cleaning and sorting system and Cyclone separating cleaning system.Main function pair As for wheat, rice, seeding corn and other crops seed, seed is relatively large in diameter, and the dimensional characteristic and air of seed and light sundries are dynamic Force characteristic difference is obvious, can satisfy the index request of loss late and percentage of impurity in watering and separation procedure by the above-mentioned technology of cleaning.

And particulate crop is primarily referred to as the seed of the vegetable crops such as rape, Chinese cabbage, carrot, seed diameter is smaller, weight Relatively light, the dimensional characteristic and aerodynamic characteristics difference of seed and light sundries are unobvious.Using existing cleaning plant, effect Bad, especially in watering and separation procedure, light sundries, which is difficult to be discharged, causes percentage of impurity higher, and loss is serious.

For traditional Winnowing type cleaning and sorting system, if by pneumatic jig system is blown out by the sundries of sieve pore, it is desirable that wind-force is enough. If wind-force is insufficient, it is difficult the sundries that vibrating screen leading portion sieve pore falls and blows out cleaning and sorting system；If sieve plate only moves back and forth, sieve Material is easy accumulation on plate, is unfavorable for the layering of material；And the system wind direction is partial to level, easily causes loss.Rape, Chinese cabbage etc. In fine grain in addition to light sundries such as stalk clast, broken seeds, also with inner septum, broken pod shell, tiny cavernous body etc. Small difference impurity is easily bonded together with above-mentioned small difference impurity, therefore be not easy to clean due to seed very little.Existing There is Winnowing type to clean under technology, small difference two kinds of losses easily occurs during mixing particulate seed cleaning: (1) seed and sundries point Layer is unobvious and is bonded on sundries and is discharged outside machine；(2) seed with light sundries by air-flow blowout machine outside.
