Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tea processing, in particular to a screening and air separation device for tea processing. Background Art
[0002] The production and processing procedures of tea vary according to different varieties, but the initial procedures are mostly picking tea leaves, sun drying, airing or withering, followed by withering, fermentation and other procedures.

[0028] In order to facilitate screening, the screening machine feed hopper 101 is located on the top side of the screening machine body 1 close to the feeding end of the screening mechanism, that is, the screening machine feed hopper 101 corresponds to the material guide ramp 106 located on the uppermost screen plate.
[0029] A screening frame 105 is installed at the lower part of the screening machine body 1, a wind separation frame 201 is installed at the lower part of the wind separation machine body 2, and a dispersion frame is installed at the disperser body 5.

[0033] In this embodiment, the excitation mechanism includes an excitation generator 107 .
[0034] In this embodiment, the first transmission mechanism includes a main transmission gear 302, a sub-transmission gear 301 and a force-bearing gear 3 that are meshed and connected in sequence. The rotating shaft of the force-bearing gear 3 passes through the air separator body 2 and is transmission-connected to the fan 204.

[0035] In order to facilitate transmission efficiency and match the different rotation speeds of the fan 204 and the scattering mechanism, the diameter of the auxiliary transmission gear 301 is larger than the diameter of the main transmission gear 302 and the diameter of the force gear 3.
[0036] In this embodiment, the second transmission mechanism includes a main connecting gear 503 and a rotating shaft 305. The rotating shaft 305 is coaxially connected to the output shaft of the main transmission gear 302. The other end of the rotating shaft 305 is coaxially provided with a first bevel gear 306. The first bevel gear 306 is meshed with a second bevel gear 307. The second bevel gear 307 is coaxially arranged on the main connecting gear 503. The rotating shaft of the main connecting gear 503 is rotatably inserted into the top of the disperser body 5, and the main connecting gear 503 is meshed with a secondary connecting gear 504.

[0038] In order to facilitate discharging, the bottom of the air separator body 2 can be provided with an inverted trapezoidal structure with both sides inclined toward the center.
[0039] In this embodiment, the disperser main body 5 includes a disperser shell and a disperser cover 507, and the dispersing mechanism includes a dispersing shaft 505, on which dispersing rods 506 are evenly distributed. The dispersing shaft 505 is rotatably inserted into the disperser cover 507, and the top end of the dispersing shaft 505 passes through the top of the disperser cover 507 and is coaxially connected to the secondary linkage gear 504.
[0040] The disperser feed port 508 is provided on the disperser cover plate 507 and is connected to the first-stage discharge hopper 202 .
[0041] In this embodiment, the driving mechanism includes an output motor 4 and a motor frame 401. The output motor 4 is installed on the motor frame 401, and the motor frame 401 is horizontally installed on the air separation frame 201.

[0042] The principle and advantages of the present invention are as follows: tea leaves are fed into the screening machine feed hopper 101, and fall onto the inclined surface of the guide ramp 106 of the primary sieve plate 108, and slide onto the primary sieve plate 108. The excitation generator 107 is operated to vibrate the guide ramp 106 and the primary sieve plate 108 simultaneously, shaking the remaining tea leaves on the guide ramp 106 onto the primary sieve plate 108, so that the tea leaves on the primary sieve plate 108 are moved along the feed end of the primary sieve plate 108 to the discharge end of the primary sieve plate 108. During the movement, the stones, tea leaves, tea stems and the like which are smaller than the holes of the first-stage sieve plate 108 are screened onto the second-stage sieve plate 109 for screening. The screened tea leaves fall out from the second-stage discharge end 103, and the stones and the like fall out from the third-stage discharge end 104. The tea leaves remaining on the first-stage sieve plate 108 enter the air separator body 2 through the first-stage discharge end 102. The output motor 4 drives the main transmission gear 302 through the output gear 303. The main transmission gear 302 drives the auxiliary transmission gear 301, and the auxiliary transmission gear 302 drives the auxiliary transmission gear 303. 1 drives the force-bearing gear 3, and the rotating shaft of the force-bearing gear 3 penetrates into the air separator main body 2 to drive the fan 204 to rotate. Due to the screening mechanism, the tea leaves falling from the air separator feed port 205 are evenly fed and blown by the fan 204. Tea leaves without agglomeration fall from the secondary discharge hopper 203, and tea leaves with agglomeration fall from the primary discharge hopper 202 and enter the disperser main body 5. At the same time, the main transmission gear 302 drives the first bevel gear 306 to rotate through the rotating shaft 305. The first bevel gear 306 The second bevel gear 307 is driven to rotate, and the second bevel gear 307 synchronously drives the main linkage gear 503 to rotate, and the main linkage gear 503 drives the secondary linkage gear 504 to rotate, and the secondary linkage gear 504 drives the breaking up shaft 505 to rotate. The breaking up rods 506 evenly distributed on the breaking up shaft 505 break up the tea clusters without damaging the unclumped large-leaf tea leaves, thereby not reducing the overall quality. The broken up tea leaves fall into the collecting box 501 and can be repeatedly input into the screening machine body 1 for screening.
[0043] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
