The specific embodiment
The present invention is described further below in conjunction with drawings and Examples.
Tea finishing machine group shown in Fig. 1~2 comprises tealeaves conveyer 2, is provided with tea finishing machine 1 at the side of described tealeaves conveyer 2, and the charging aperture 101 of this tea finishing machine 1 is connected with the discharging opening 206 of described tealeaves conveyer 2.Wherein, tea finishing machine 1 comprises the frame 103, at least two sieve plates 105 that are positioned at described charging aperture 101 belows that are provided with charging aperture 101, is installed on this frame 103 and the vibrating mechanism that links to each other with described each sieve plate 105, and the discharging opening 109 corresponding with each sieve plate 105, one by one away from described charging aperture 101, described each discharging opening 109 is separately positioned on corresponding sieve plate 105 belows to described each sieve plate 105 with stepped downward arrangement mode.
Shown in Fig. 1~2, tealeaves to be sieved enters the charging aperture 101 of tea finishing machine 1 by tealeaves conveyer 2, under the effect of vibrating mechanism, the tealeaves that falls into upper level sieve plate 105 from this charging aperture 101 is towards 105 motions of next stage sieve plate, this process will be carried out the screening first time to tealeaves, the tealeaves that sifts out directly falls into corresponding discharging opening 109, and the tealeaves that is not sifted out then moves forward and enters next stage sieve plate 105 and carries out programmed screening.Therefore, this tea finishing machine can carry out multistage screening to tealeaves according to the step quantity that sieve plate 105 is installed, and improves the tealeaves screening efficiency, and because sieve plate 105 is the upper-lower position relation with discharging opening 109, equipment overall structure is compact and reasonable more.
The applicant of particular note, each discharging opening 109 can be with each sieve plate 105 one to one, also can be a discharging opening 109 corresponding two or more sieve plates 105.And sieve plates 105 at different levels are not the different specification of certain employing yet.When adjacent two-stage or what sieve plate 105 adopted same sieve plate 105, these sieve plates 105 just can discharging opening 109 of correspondence.
