Furthermore, a pressing strip is arranged at the edge part of the material guide piece close to the inner wall of the discharge pipe, a connecting groove matched with the edge part of the material guide piece is formed in the pressing strip, a brush facing the inner wall of the discharge pipe is arranged on the pressing strip, and the brush is abutted against the inner wall of the discharge pipe.

Furthermore, the hairbrush comprises a plurality of closely distributed comb strips made of plastic materials, and the comb strips are elastic.

Adopt the thick unloading of weighing of tealeaves of the structure realization of the guide piece of spiral and unloading pipe, not only can improve unloading efficiency, and, because the unloading cross-section that forms between guide piece and the unloading pipe is less, can improve the unloading precision, in order to avoid tealeaves to cause the extrusion and the rubbing bits of broken glass to tealeaves at the clearance between guide piece lateral margin and the unloading intraductal wall and the removal of guide piece on the pipe wall, at the marginal part brush of guide piece, not only can carry out effectual protection to this regional tealeaves, and can clear away the tealeaves residue in the unloading pipe, avoided the residue to pile up and the relatively poor condition of tealeaves quality that once only discharges and cause. The comb strip on the brush has elasticity, can have the effect of dialling the material to tealeaves when the ejection of compact, avoids because of the inhomogeneous unloading that tealeaves pegged graft each other and cause.

Through the structure of cylinder, driving lever and group board, can realize the driving lever before opening the shutter and dial exempting from of board and contact to avoid shutter controlling means to the influence of weighing precision.

The coarse tea weighing mechanism and the fine tea weighing mechanism are started simultaneously, feeding is carried out on the weighing hopper, after the specified weight is reached, the coarse tea weighing mechanism is suspended, feeding is continued through the fine tea weighing mechanism, after the tea leaves with the set weight enter the weighing hopper, the fine tea weighing mechanism is suspended, the air cylinder is started, the fine tea weighing mechanism is discharged, and the operation is circulated.
