As a kind of preferred embodiment, Fig. 7 shows has 6 clamp mechanism 9 of arranging along the even circumferential of main shaft 7.When clamping plate 10 were clamped tealeaves, existing another clamping plate were being done the separation of stalk leaf, and the tea stalk that also has clamping plate will remove blade discharges.On average, main shaft 7 whenever turns over 60 °, can finish and once obstruct the leaf separation, so efficient is higher.Certainly, the number of clamping plate 10 and arrangement thereof can be not limited.When the clamping plate number increased, the processing speed that the stalk leaf separates can further be accelerated.In addition, increase the feeding chute number on lower feedboard 11 and the enterprising flitch 12, also can improve the efficient that the stalk leaf separates.

During the work of the utility model stalk leaf seperator, preferably be equipped with the device of an even feed of energy, comparatively be typically vibra shoot in tea machine industry, more suitable is to make the vertically carding machine of queuing of tealeaves.The automatization level of separating for improving the stalk leaf also needs a conveyer belt, sends the tealeaves in the returning charge groove back to tea inlet bucket, to realize cyclic process.Theoretically, it suppose to have 50% tea stalk down towards being at random after tealeaves was fallen on each chute of inclination feedboard, can be clamped by clamping plate and was used for the separation of stalk leaf, and all the other 50% return tea inlet bucket; The tealeaves that returns carries out the processing second time, can 50% tealeaves be separated again; Therefore, with regard to the utility model stalk leaf seperator, process two passages and can implement the separation of stalk leaf to 75% tealeaves.So cyclic process can make the stalk leaf separate fully.
