Description
Technical field
The invention belongs to agricultural byproducts processing technical field, especially relate to a kind of Tea screening machine.
Background technology
It is usually vibrating screen panel screening or wind filter in traditional Tea screening machine.Vibrating screen panel screening is that Folium Camelliae sinensis are straight
Connect and be poured over screening on the net, Folium Camelliae sinensis are screened in online vibrations of screening under screening online shaking device effect.Wind filter
It is then the wind-force mechanism by setting on Tea screening machine, is varied in weight in itself by Folium Camelliae sinensis, using wind-force by Different Weight
Folium Camelliae sinensis are blown to different rewinding mouths to reach the effect to Folium Camelliae sinensis screening.Two methods often all need in Folium Camelliae sinensis screening process
To complete the sieving and grading to Folium Camelliae sinensis using screening net.And existing screening nets presence installation complexity, cost of manufacture height, practicality
Property poor, screening effect difference the problems such as.Especially during wind filter, the position in simple adjustment classification chamber is to reach to wind-force
The Folium Camelliae sinensis of screening carry out classification and collect, but because the speed of air-flow and direction uncertainty make Folium Camelliae sinensis sieving and grading in practical operation
Fall flat.Meanwhile, the impurity after existing Tea screening machine is not often also to Folium Camelliae sinensis screening is collected, and this is bright
Aobvious is a kind of wasting of resources.For this reason, people have carried out long-term exploration it is proposed that various solution.
For example, Chinese patent literature disclose a kind of Tea screening machine [application number: 200920182650.7], including
The top of frame, rack-mounted air channel and the fan being connected with air channel one end has charging aperture near the position of fan,
The top of charging aperture is provided with chute feeder, and the bottom in air channel has a big discharging opening near the position of fan, described big funnel
Lower exit port is provided with a tilted-putted screening net.
Although Folium Camelliae sinensis can be preferably classified by such scheme using fan and air channel cooperation screening plant.But it is overall
Structure design is unreasonable, and the thin stalk of the Folium Camelliae sinensis producing in Folium Camelliae sinensis screening process and tea dust can not be collected, Folium Camelliae sinensis sieving and grading can
Control property is not strong, and tea dry sorting precision is not high.
Content of the invention
The purpose of the present invention is for the problems referred to above, provides one kind to make Folium Camelliae sinensis sieving and grading more accurate and can collect to screen
The Tea screening machine of impurity in journey.
For reaching above-mentioned purpose, present invention employs following technical proposal: this Tea screening machine, including casing, in casing
One end be connected with air inlet mechanism, the top being connected with air inlet mechanism one end in casing is connected with feeding mechanism, the one of casing
Side lower part is provided with elongated horizontal outlet it is characterised in that being provided with some Screen assemblies in described casing, described sieve
Subassembly is laterally distributed in horizontal outlet inner side and is resisted against cabinet wall, is formed and screen out between two adjacent Screen assemblies
Mouthful and each Screen assemblies can be under external force along horizontal outlet transverse shifting.
Obviously, Screen assemblies can adjust the fine graded mark of Folium Camelliae sinensis according to the quality of concrete Folium Camelliae sinensis by transverse shifting
Standard, Screen assemblies are laterally distributed in horizontal outlet inner side and are resisted against cabinet wall, closely connect with the side plate of horizontal outlet upper end
Touch so that Folium Camelliae sinensis can not drop in the inner chamber of Screen assemblies, but the screening out between two neighboring Screen assemblies that all fall
In mouthful, the screening beneficial to Folium Camelliae sinensis is collected.
In above-mentioned Tea screening machine, described Screen assemblies include first panel and the second panel of symmetrical configuration,
Described first panel and second panel are hinged by articulated structure, and form angle between first panel and second panel,
The opening of described angle is towards outside horizontal outlet.Articulated structure allows Screen assemblies freely to adjust height and width,
Thus beneficial to the standard setting up new sieving and grading, fine graded beneficial to Folium Camelliae sinensis.
In above-mentioned Tea screening machine, the bottom of described casing is provided with hang plate, and described casing sidepiece is provided with side
Plate, forms above-mentioned horizontal outlet between described hang plate and side plate；The size of described angle is 20 ° -60 °；Described
Articulated structure is damping articulated structure.Further, laterally outlet is beneficial to the collection of Folium Camelliae sinensis.The size of angle is 20 ° -60 °
Change scope the most suitable, angle is too little, is unfavorable for the stable placement of Screen assemblies, too greatly, then departs from the side plate of casing, unfavorable
Categorised collection in Folium Camelliae sinensis.Damping articulated structure has cushioning effect to the folding of first panel and second panel it is ensured that screening group
The stability of part.
As the optimized scheme of the present embodiment, described corner dimension is 40 °.
In above-mentioned Tea screening machine, described air inlet mechanism includes aerator, is connected with blast pipe on aerator
One end, the other end of described blast pipe is connected with casing, is provided with air-flow can be made evenly distributedly defeated in described blast pipe

It is connected with casing 1, in described blast pipe 22, be provided with the equal compress mechanism of qi structure 221 that air-flow can be made evenly distributedly to export.Obviously,
Aerator 21 provides the air-flow of screening tea dry sorting, very well the air-flow that aerator 21 produces can be collected union by blast pipe 22
Middle output, arranges equal compress mechanism of qi structure 221 and can guarantee that the air-flow entering from blast pipe 22 evenly distributedly exports casing 1.
Simultaneously described equal compress mechanism of qi structure 221 includes the separator 22a in blast pipe 22, described separator
22a is fixed on blast pipe 22 inwall thus forming some being uniformly distributed and the going out of area equation in the air outlet 22c of blast pipe 22
Air holes.Separator 22a runs through in whole blast pipe 22, can be relatively slide fix in blast pipe 22 inwall or welding or
Bolt connection or riveting etc. are fixed on inwall.Air outlet 22c is separated into the exhaust vent of area equation, quilt by separator 22a
The exhaust vent separating can be shape difference but area identical polygon.
For reaching optimal wind filter effect, rectangular, the described separator 22a in the cross section of described blast pipe 22
Including some demarcation strip 22a1 arranged in a crossed manner.Blast pipe 22 cross section rectangle can be square or rectangle, separator 22a
Can be that decussation, inclination intersection, axial line intersection, avris intersection etc. are divided for satisfaction including demarcation strip 22a1 arranged in a crossed manner
The cross section of dividing plate 22a1 is rectangle, triangle, trapezoidal, honeycombed, circle, the interleaved mode of any one in annular.Point
Dividing plate 22a1 can be arranged at air outlet 22c or axially penetrate through whole blast pipe 22., described blast pipe 22 is from air inlet
The size of 22b one end becomes larger towards the size of air outlet 22c one end, and air inlet 22b be smaller in size than air outlet 22c's
Size；Described blast pipe 22 is in bending.
Consider to optimize air-out effect, air inlet 22b is smaller in size than air outlet 22c size and advantageously reduces air inlet 22b phase
The working strength of aerator 21 even.Blast pipe 22 body becomes larger favorably to air outlet 22c size from air inlet 22b simultaneously
More preferably separate air-flow for separator 22a condition is provided in slowing down the air velocity of air inlet 22b, current rate.Further
Say, blast pipe 22 is designed to bending and meets fluid mechanics principle, be the optimization design of structure of tube body.
