Description

Tea screening machine
Technical field
The utility model belongs to agricultural byproducts processing technical field, especially relates to a kind of Tea screening machine.
Background technology
Vibrating screen panel screening or wind filter is generally in traditional Tea screening machine.It is online that vibrating screen panel screening and tealeaves are poured directly into screening, and under the online shaking device effect of screening, tealeaves screens in the online vibrations of screening.Wind filter is then the wind-force mechanism by Tea screening machine is arranged, and is varied in weight by tealeaves itself, utilizes wind-force to be blown by the tealeaves of Different Weight 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 tealeaves screening process.The problems such as and existing screening net exists installation complexity, cost of manufacture is high, poor practicability, screening effect difference.Especially, in wind filter process, the position in simple adjustment classification chamber carries out classification collection to reach to the tealeaves of wind filter, but because the speed of air-flow and direction uncertainty make tealeaves sieving and grading fall flat in practical operation.Meanwhile, existing Tea screening machine is not often also collected the impurity after tealeaves screening, and this is obviously a kind of wasting of resources.For this reason, people have carried out long-term exploration, propose various solution.
Such as, Chinese patent literature discloses a kind of Tea screening machine [application number: 200920182650.7], comprise support, rack-mounted air channel and the top of fan that is connected with one end, air channel has 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, the lower exit port 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 classification preferably.But overall construction design is unreasonable, the tealeaves produced in tealeaves screening process carefully obstructs can not be collected with tea dust, and the controllability of tealeaves sieving and grading is not strong, and tea dry sorting precision is not high.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of and makes tealeaves sieving and grading more accurately and can collect the Tea screening machine of impurity in screening process.
For achieving the above object, the utility model have employed following technical proposal: this Tea screening machine, comprise casing, air inlet mechanism is connected with in one end of casing, the top being connected with air inlet mechanism one end at casing is connected with feeding mechanism, elongated transverse direction outlet is provided with at a side lower part of casing, it is characterized in that, some Screen assemblies are provided with in described casing, described Screen assemblies is laterally distributed in and laterally exports inner side and be resisted against cabinet wall, screening outlet is formed and each Screen assemblies can under external force along laterally export transverse shifting between two adjacent Screen assemblies.
Obviously, Screen assemblies can adjust the fine graded standard of tealeaves according to the quality of concrete tealeaves by transverse shifting, Screen assemblies is laterally distributed in and laterally exports inner side and be resisted against cabinet wall, with the side plate close contact laterally exporting upper end, make tealeaves can not drop in the inner chamber of Screen assemblies, but all drop in the screening outlet between adjacent two Screen assemblies, the screening being beneficial to tealeaves is collected.
In above-mentioned Tea screening machine, described Screen assemblies comprises the first panel and second panel of symmetrical configuration, the first described 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 laterally exporting outside.Articulated structure makes Screen assemblies can free adjustment height and width, thus is beneficial to the standard 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 transverse direction 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 tealeaves.The size of angle is 20 °-60 ° change scopes the suitableeest, and angle is too little, is unfavorable for the stable placement of Screen assemblies, too greatly, then departs from the side plate of casing, is unfavorable for the categorised collection of tealeaves.The folding of damping articulated structure to the first panel and the second panel has cushioning effect, ensures the stability of Screen assemblies.
