Description
Technical field
The invention belongs to agricultural byproducts processing technical field, especially relate to a kind of Tea screening machine.
Background technology
In traditional Tea screening machine, be generally vibrating screen panel screening or wind filter.Vibrating screen panel screening is that tealeaves is poured directly into screening on the net, and under the online shaking device effect of screening, tealeaves screens in the online vibrations of screening.Wind filter is the wind-force mechanism by arranging on Tea screening machine, varies in weight by tealeaves itself, utilizes wind-force that the tealeaves of Different Weight is blown to different rewinding mouths to reach the effect to tealeaves screening.Two kinds of methods often all need to use screening net to complete the sieving and grading to tealeaves in to tealeaves screening process.And existing screening net exists and installs complicatedly, cost of manufacture is high, poor practicability, the problem such as screening effect is poor.Especially in wind filter process, simply adjust the position in classification chamber, to reach, the tealeaves of wind filter is carried out to classification collection, but in practical operation, speed and the direction uncertainty because of air-flow falls flat tealeaves sieving and grading.Meanwhile, existing Tea screening machine is not often also collected tealeaves screening impurity later, and this is obviously a kind of wasting of resources.For this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of Tea screening machine [application number: 200920182650.7], comprise that support, rack-mounted air channel and the top of the fan being connected with one end, air channel have charging aperture near the position of fan, the top of charging aperture is provided with chute feeder, the bottom in air channel has a large discharging opening near the position of fan, and the below outlet of described large funnel is provided with a tilted-putted screening net.
Although such scheme can utilize fan and air channel to coordinate screening plant that tealeaves is carried out to classification preferably.But overall construction design is unreasonable, the thin stalk of tealeaves and the tea dust that in tealeaves screening process, produce can not be collected, and the controllability of tealeaves sieving and grading is not strong, and tea dry sorting precision is not high.
Summary of the invention
The object of the invention is for the problems referred to above, a kind of Tea screening machine that makes tealeaves sieving and grading more accurately and can collect impurity in screening process is provided.
For achieving the above object, the present invention has adopted following technical proposal: this Tea screening machine, comprise casing, one end at casing is connected with air inlet mechanism, the top that is connected with air inlet mechanism one end at casing is connected with feeding mechanism, be provided with elongated horizontal outlet at a side lower part of casing, it is characterized in that, in described casing, be provided with some Screen assemblies, described Screen assemblies cross direction profiles is laterally exporting inner side and is being resisted against cabinet wall, between two adjacent Screen assemblies, form screening outlet and each Screen assemblies and can transversely export under external force transverse shifting.
Obviously, Screen assemblies can be adjusted the fine graded standard of tealeaves by transverse shifting according to the quality of concrete tealeaves, Screen assemblies cross direction profiles is laterally exporting inner side and is being resisted against cabinet wall, side plate close contact with horizontal outlet upper end, tealeaves can not be dropped in the inner chamber of Screen assemblies, but all drop in the screening outlet between adjacent two Screen assemblies, the screening that is beneficial to tealeaves is collected.
In above-mentioned Tea screening machine, described Screen assemblies comprises the first panel and second panel of symmetrical configuration, described the first panel and the second panel are hinged by articulated structure, and form angle between the first panel and the second panel, and the opening of described angle is towards horizontal outlet outside.Articulated structure makes the Screen assemblies can free adjustment height and width, thereby is beneficial to the standard of setting up new sieving and grading, is beneficial to the fine graded of tealeaves.
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 export the collection that is beneficial to tealeaves.The size of angle is 20 ° of-60 ° of change scopes the suitableeest, and angle is too little, is unfavorable for the stable placement of Screen assemblies, too large, departs from the side plate of casing, is unfavorable for the categorised collection of tealeaves.Damping articulated structure has cushioning effect to the folding of the first panel and the second panel, ensures the stability of Screen assemblies.
