The end, close to the bunching sleeve 16, of the second transmission belt 10 is provided with a first blanking hopper 17, and the first blanking hopper 17 extends into the feed port 5.

100601 Further, in the embodiments, the separation effect of the brush separation assembly for the tea leaves and the tea stalks is preferably achieved. The roller body 91 includes an outer roller body 911 and an inner roller body 912. The inner roller body 911 axially sleeves the interior of the outer roller body 912. Radial holes 913 are distributed in the surface of the outer roller body 911. Each of the radial holes 913 extends to the surface of the inner roller body 912 along the radial direction of the outer roller body 911. A radial plate 914 is mounted inside the radial hole 913, and the radial plate 914 is fixedly connected with the inner roller body 912. The circumferential length of the radial hole 913 is larger than the circumferential length of the radial plate 914, so that the outer roller body 911 and the inner roller body 912 can rotate relatively.

100611 The brush group 92 includes first brushes 921 and second brushes 922. The second brush 922 is fixedly mounted at the end, extending from the radial hole 913 to the surface of the outer roller body 911, of the radial plate 914. Each of two sides of the second brush 922 is arranged with a corresponding one of the first brushes 921 on the surface of the outer roller body 911. Then, the outer roller body 911 and the inner roller body 912 can rotate relatively, so that the radial plate 914 can swing inside the radial hole 913. The radial plate 914 swings, so that relatively staggered movement can occur between the first brushes 921 and the second brushes 922.

100621 That is, the surface of the outer roller body 911 is provided with multiple brush groups 92, and each of the brush groups 92 is arranged on the surface of the outer roller body 911 along the length direction of the outer roller body 911 100631 In the embodiments, the inner roller body 912 is coaxially and fixedly sleeved with the rotating shaft 93. The end, away from the fifth transmission pulley 40, of the rotating shaft 93 is sleeved with a hysteresis rotating device 18. The other end, close to the fifth transmission pulley 40, of the rotating shaft 93 is sleeved with a coil spring 23. The outer ring of the coil spring 23 is connected with the end surface of the outer roller body 911. The inner ring of the coil spring 23 is fixedly connected with the end of the inner roller body 912.

100641 The specific realization principle is as follows: under the transmission of the fifth transmission pulley 40, the rotating shaft 93 is driven to rotate, and the rotating shaft 93 drives the inner roller body 912 to rotate. Because of the connection of the coil spring 23, the coil spring 23 drives the outer roller body 911 to rotate synchronously. The outer ring of the coil spring 23 is connected with the end surface of the outer roller body 911, and the inner ring of the coil spring 23 is connected with the end surface of the inner roller body 912. The coil spring 23 is configured for conversion of elastic potential energy on the plane of the spring, so that in the initial state, the radial plate 914 abuts against one side of the radial hole 913, and the whole of the first brushes 921 and the second brushes 922 is kept consistent.

100651 When the outer roller body 911 and the inner roller body 912 rotate, under the action of the hysteresis rotating device 18, an acting force opposite to the rotating direction is applied to the outer roller body 911, so that the outer roller body 911 and the inner roller body 912 rotate relatively (or the outer roller body 911 tends to be stationary, and at that time, the coil spring 23 obtains elastic potential energy). The first brush 921 and the second brush 922 start to be staggered, and the radial plate 914 rotates to the other side of the radial hole 913. When the hysteresis rotating device 18 cancels the opposing force instantaneously, the initial state is restored when the elastic potential energy of the coil spring 23 is converted into mechanical energy (so that the radial plate 914 abuts against one side of the radial hole 913 in the initial state).

100661 The hysteresis rotating device 18 is configured for applying the force opposite to the rotating direction of the fifth transmission pulley 40 and canceling the repeated cycle state of the force, so that the first brush 921 and the second brush 922 are always in a changing state of being staggered and restoring consistency The purpose of the process is to vibrate the tea leaves entering between two adjacent brush groups 92. At the moment of being staggered, the first brush 921 and the second brush 922 are in a relatively static state of being staggered. At the moment, the tea leaves and the tea stalks are staggered by vibration, and then the tea leaves and the tea stalks falling onto the second transmission belt 10 can be separated.

100671 Further, in the embodiments, the hysteresis rotating device 18 includes a corrugated wheel 181 rotatably sleeving the rotating shaft 93. The end surface, close to the corrugated wheel 181, of the outer roller body 911 is provided with a groove set ring 182. Each groove 183 of the groove set ring 182 extends along the axial direction of the outer roller body 911. A corresponding guide wedge 184 is mounted inside each groove 183 of the groove set ring 182. The guide wedge 184 is mounted inside the groove 183 of the groove set ring 182 via a spring.

100681 The corrugated wheel 181 is relatively stationary with the rotating shaft 93, and the corrugated wheel 181 is configured for forcing the guide wedge 184 to reciprocate along the axial direction of the outer roller body 911 under the action of the spring when the outer roller body 911 rotates.

100691 Further, the present disclosure further provides an integral structure for installing the separator, specifically further including a shell 19 for sleeving the whole separator. The upper part of the shell 19 is provided with a feed hopper 20. The feed hopper 20 is positioned above the first transmission belt 8. The first discharge hopper 21 is arranged on one side surface of the shell 19 positioned below the first transmission belt 8. When the brush separation assembly 9 works, the tea leaves and the tea stalks are staggered by vibration, and then the tea leaves and the tea stalks falling onto the second transmission belt 10 can be separated. And the partially separated tea stalks are discharged from the first discharge hopper 21. The edge, extending to the interior of the shell 19, of the first discharge hopper 21 is in contact with the side of the second transmission belt 10. The second transmission belt 10 is configured for conveying the tea leaves and tea stalks separated by the brush separation assembly 9 to the feed port 5, and the brush separation assembly 9 sweeps the tea leaves falling into the second transmission belt 10 out of the second transmission belt 10. The other side of the shell 19 is provided with a second discharge hopper 22. The tea leaves are discharged from the through holes and then screened by the screen mesh assembly, and finally discharged from the second discharge hopper 22.

100701 Further, a turbofan is mounted on the surface, facing the outer roller body 911, of the shell 19, and the rotating direction of the turbofan is opposite to that of the rotating shaft 93. That is, the swirling wind blown by the turbofan to the roller body 9 is opposite to the overall rotating direction of the roller body 9. In cooperation with the staggered movement between the first brush 921 and the second brush 922 generated by the hysteresis rotation between the outer roller body 911 and the inner roller body 912, the tea leaves are blown due to the raising actions of the tea leaves, so that the tea leaves float in an overturning mode. The tea leaves are larger in area subjected to swirling wind, and the influence of swirling wind on the generated floating is higher than that of the tea stalks, so that the tea stalks can be separated from the tea leaves and fallen down more quickly 100711 The above embodiments are only exemplary embodiments of the application, and are not intended to limit the application. The scope of protection of the application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the application within the scope of essence and protection, and these modifications or equivalent substitutions should also be regarded as falling within the scope of protection of the application.
