Description

A kind of large-tonnage positive pressure specific weight type sqeed sorting machine

Technical field

The utility model relates to agricultural mechanical fields, and in particular to a kind of large-tonnage positive pressure specific gravity of cereals seed cleaning Formula sqeed sorting machine.

Background technique

Cereal seed will carry out selected in front of sales, so that its cleanliness is up to state standards, the method and apparatus of seed cleaning It is varied, but nothing more than pneumatic jig choosing, major class more several than gravity treatment, gravity preparation, indent separating.Wherein there are positive-pressure type and negative pressure again than gravity treatment Point of formula, primary structure of the positive-pressure type than gravity treatment: is made of rack, air blower, vibration device, sifting bed etc..It works than gravity treatment former A kind of foreign seeds extractor that reason is exactly the specific gravity difference using cereal superiority and inferiority seed and is designed, cereal are sorted by sifting bed, sieve Bed is rectangular, and longitudinal feeding mouth end is high, and discharge port end is low, is laterally also that side is high, the setting of side low dip, and cereal exists when work Sifting bed upper surface rolls, between the forced draft formed below by air blower enters cereal kernel across sieve, and it is mutual with seed Effect generates layering, different using the opposite specific gravity of seed in the gas flow, so that weight seed is sunk, light seed floats.Simultaneously because The heavier seed touched is transversely pushed to sifting bed high side by the vibration of sifting bed, and lighter seed is transversely mobile to sifting bed downside, Because entire sifting bed outlet is lower than entrance, by means of vibration, weight seed is along high side, and light seed is along low side surface simultaneously to outlet end It is mobile, eventually fall into respective discharging gate.Still there is a mixed zone in region between weight, light seed, will mix the seed in section again Entrance back to sifting bed enters next circulation, and entire assorting room is completed.

For current positive-pressure type is than the structure of gravity treatment, air blower has more independent blowers or more Fans lontitudinal series It is driven with an axis, the former bull power, power consumption is big, cost is high；The latter is architectural limitation, the blower when manufacturing large-tonnage than gravity treatment Serial number is limited, and wind-force is insufficient, is unable to satisfy selected requirement.If increasing blower number, knot with the method for lengthening whole length Fruit is that sifting bed fore-and-aft distance is also elongated, and slowly, machine utilization aggravates for seed outflow, and power consumption is big, low efficiency.Actually sieved than gravity treatment It after longitudinal arrival certain length of bed, does not work to sorting, then lengthening can only increase machine utilization；Opposite increase appropriate Transverse width can make the sifting bed bed of material thinning, and more advantageous separation, yield can increase, more efficient.Compare gravity treatment in design large-tonnage When, the Aspect Ratio of sifting bed how is controlled, blower task performance is given full play to, improves the separating effect of sifting bed, is this technology leather New main points.

Summary of the invention

The technical problem to be solved by the present invention is to provide a kind of large-tonnage positive pressure specific weight type sqeed sorting machine, sifting bed length-width ratios Example is reasonable, air supplying is uniform, reduces energy consumption, separating effect more preferably, more efficient.

The utility model is achieved through the following technical solutions:

A kind of large-tonnage positive pressure specific weight type sqeed sorting machine, including the vibrating screen bed and air blower being set in rack, vibrating screen bed Rectangular, longitudinal feeding mouth end is obliquely installed higher than discharge port end, and lateral one side of bed surface is obliquely installed to other side height, drum Blower is located at below vibrating screen bed, and more air blowers are laterally one group two-by-two, and longitudinal multiple groups row sets, and every group of two air blower connects Spindle is connected, and motor driven connection adjacent sets air blower is set between every two groups.

The utility model is further improved scheme, and the rack is equipped with regulating mechanism, and connection vibrating screen bed adjusts it Lateral inclination angle.

The further improvement project of the utility model is that the vibrating screen bed surface is metallic sieve.

The further improvement project of the utility model is, the discharge port end of the vibrating screen bed is from lateral bed surface high side to low Side successively sets up finished product mouth separately, returns sorting mouth, impurity mouth.

The utility model compared with prior art, has following obvious advantage:

Since laterally series connection is one group to two air blowers, longitudinal multiple groups row sets the utility model, shortens large-tonnage specific weight type Sqeed sorting machine entire length increases sifting bed width, keeps sifting bed length ratio reasonable, and motor driven connection phase is set between longitudinal every two groups Neighbour's group air blower, air supplying is sufficient and uniform, reduces energy consumption, separating effect is good, high-efficient.

Detailed description of the invention

Fig. 1 is the utility model side structure schematic view.

Fig. 2 is the utility model overlooking structure diagram.

Specific embodiment

As shown in Figure 1 and Figure 2, the utility model includes the vibrating screen bed 1 and air blower 2, regulating mechanism 5 in rack, Vibrating screen bed 1 is rectangular, and surface is metallic sieve, and 11 end of longitudinal feeding mouth is higher than 12 end of discharge port and is obliquely installed, lateral bed One side of face is obliquely installed to other side height, and air blower 3 is located at 1 lower section of vibrating screen bed, and eight air blowers 3 are laterally one two-by-two Group, longitudinal four groups of rows set, and every group of two air blowers are connected with connecting shaft 4, and a motor 5 is set between every two groups and is drivingly connected adjacent sets drum Blower 3.

The regulating mechanism 5 being arranged in the rack, connection vibrating screen bed 1 adjust its lateral inclination angle.

12 end of discharge port of the vibrating screen bed successively sets up finished product mouth 121 separately from lateral bed surface high side to downside, returns sorting Mouth 122, impurity mouth 123.

Cereal is rolled in vibrating screen bed upper surface when work, is entered below by the forced draft that air blower is formed across sieve Between cereal kernel, and interacts with seed and generate layering, it is different using the opposite specific gravity of seed in the gas flow, make under weight seed Heavy, light seed floats.Simultaneously because the heavier seed touched, is transversely pushed to sifting bed high side, lighter seed by the vibration of sifting bed Grain is transversely mobile to sifting bed downside, because entire vibrating screen bed outlet is lower than entrance, by means of vibration, weight seed is along high side Face, light seed are moved to outlet end simultaneously along low side surface, eventually fall into respective discharging gate.Still there is region between weight, light seed The entrance that the seed for mixing section again returns to sifting bed is entered next circulation by one mixed zone, and entire assorting room is completed.

Since laterally series connection is one group to two air blowers, longitudinal multiple groups row is set, and it is whole to shorten large-tonnage specific weight type sqeed sorting machine Length increases vibrating screen bed width, keeps sifting bed length ratio reasonable, and motor driven connection adjacent sets drum is set between longitudinal every two groups Blower, air supplying is sufficient and uniform, reduces energy consumption, separating effect is good, high-efficient.
