There is an elastic support mechanism 500 , which is connected to the frame, and an airflow disturbance mechanism 600 is installed on the stem separation cylinder 300 , and the airflow disturbance mechanism 600 is used to disturb the material in the stem separation cylinder 300 . The working principle and advantages of the embodiment of the present invention are that: tea leaves containing impurities such as tea stems and tea residues are transported into the feeding cylinder 100 through a conveyor belt, and the air flow of the airflow disturbance mechanism 600 blows the tea leaves gradually falling into the feeding cylinder 100 , so that the tea residues with smaller weight enter the tea residue collecting mechanism to be collected; because the feeding cylinder 100 adopts the form of inclined setting, the tea leaves gradually enter the stem and leaf separation cylinder 300 from the feeding cylinder 100 through the transfer cylinder 200, and the stems and leaves are separated. The drum 300 is driven by the driving mechanism 400 to rotate eccentrically, and the airflow disturbance mechanism 600 blows the air into the stem separation drum 300, and the weight of the tea leaves is lower than that of the tea stems, that is, the tea leaves stay in the stem separation drum 300 for a longer time than the tea leaves. The stalks separate the tea stalks from the tea leaves, and are collected separately at the outlet of the stalk-leaf separating cylinder 300, and the tea stalks and the tea leaves are separated in the stalk-leaf separating cylinder 300 without causing damage to the tea leaves. In terms of the separation method of the existing tea stalk separating rollers, the integrity of the tea leaves is extremely high, thereby making the tea leaves intact and improving the quality of the tea leaves. In conclusion, the present invention can simultaneously complete the tea stalks and the tea leaves in the tea leaves. The separation operation of the slag greatly improves the impurity removal efficiency of the tea leaves, and the invention has a simple structure and convenient operation.

As a preferred embodiment of the present invention, as shown in FIG. 4 , the inclined setting of the feeding cylinder 100 is to facilitate the entry of tea leaves and tea stems into the stem-leaf separation cylinder 300 , and under the action of the airflow disturbance mechanism 600 , the light-weight tea Slag, debris, etc. are blown into the tea dregs collection mechanism. In this embodiment, a feeding port 101 is constructed on the feeding cylinder 100 , and a bell mouth 102 is constructed on the upper end of the feeding port 101 , so that the tea leaves can enter the feeding cylinder 100 continuously in batches. In this embodiment, a separator net 103 is installed in the feeding cylinder 100 and near the tea residue collecting mechanism. The function of the separator net 103 is to isolate the tea leaves with large volume and prevent them from entering the tea residue collecting mechanism.

As a preferred embodiment of the present invention, as shown in FIG. 5 , in order to make the stem separation drum 300 and the feeding drum 100 have a certain circumferential displacement in the process of driving the stem separation drum 300 to move eccentrically, the drive mechanism 400 has a certain circumferential displacement. And the circumferential displacement can be set to transfer the two through a component, so as to facilitate the passage of tea leaves and tea stems. Specifically, the component is the above-mentioned adapter cylinder 200, and the adapter barrel 200 is a telescopic type. The cylindrical structure is adapted to the twisting of the stem separation drum 300, one end of the cylindrical structure is detachably connected to the lower mouth end of the feeding drum 100, and the other end of the cylindrical structure is connected with the feeding end of the stem separation drum 300. Turn the connection. Moreover, due to the telescopic and twisting of the transfer drum 200 , the tea leaves and the tea stems are initially screened in the transfer drum 200 , which promotes the separation of the two and the smooth passage of the transfer drum 200 .

As a preferred embodiment of the present invention, as shown in FIG. 6 , the stem and leaf separation cylinder 300 includes a separation cylinder 301 . In order to make the feeding speeds of tea stems and tea leaves different in the separation cylinder 301 Reduction along the conveying direction of the material, that is, during the eccentric rotation of the separation cylinder 301, the heavier tea stems move faster in the separation cylinder 301 than the tea leaves, and because the diameter of the separation cylinder 301 is reduced, it is closer to the feeding cylinder 100. The accumulated amount of tea leaves is greater than the outlet end of the separation cylinder 301, so that the tea stalks leave the separation cylinder 301 first, and are thrown a certain distance under the interaction of gravity and the speed of leaving the separation cylinder 301, at a predetermined position The tea stalk collection frame is used for collection, and the speed and weight of the tea leaves are relatively low, so that the distance the tea leaves are thrown by the separating cylinder 301 is smaller than the tea stalk, and a tea stalk collection frame is set at this position for collection. In this embodiment, in order to make the tea leaves slide down smoothly, a discharge cover 303 is constructed on the small diameter end of the separation cylinder 301 , and the tea leaves slide down from the inner wall of the discharge cover 303 . The drive mechanism 400 of this embodiment is connected to the discharge cover 303 by transmission, so that the shaking degree of the discharge end of the separation cylinder 301 is greater than that of the feed end, and the problem of mixing tea stems and tea leaves at the discharge port is avoided.

In this way, the air distribution ring pipe 601 far away from the separation cylinder 301 blows and disturbs the material in the separation cylinder 301, which has a strong reverse blowing effect on the material, which further limits the speed of the lighter tea leaves. Restricted, but the degree of obstruction of the tea stems is much less than that of the tea leaves, so that the tea leaves and the tea stems are sufficiently separated. The air distribution ring pipe 601 close to the separation cylinder 301 blows and disturbs the material in the separation cylinder 301, and it has a large blowing ability to the material along the radial direction of the separation cylinder 301, and further has a good disturbance effect on the tea stems and tea leaves. With the eccentric rotation of the separation cylinder 301, the two are fully separated to avoid the problem of sticking between the tea stems and the tea leaves. Moreover, since the separation cylinder 301 keeps rotating continuously, the gas emitted by the airflow disturbance mechanism 600 flows in a slight swirling direction under the rotation of the separation cylinder 301, thereby separating the tea leaves from the tea stalks and dropping the feeding cylinder 100. The tea residues etc. are separated out and enter the tea residue collection mechanism.
