[0028] like Figure 1-Figure 5As shown, a collecting assembly is arranged below the conveyor belt 6, and the collecting assembly consists of a material holding box 8, a second servo motor 9, a rotating plate 10, a fixed plate 11, a control panel 12, an inclined plate 13, a material stopper 21, a lifting inclined plate 22, a guide rod 23, a spring 24 and a pressure sensor 25. A material holding box 8 is fixedly arranged on the side of the support plate 2, and a second servo motor 9 and a control panel 12 are fixedly installed on the front of the material holding box 8. The output end of the second servo motor 9 passes through the material holding box 8 and is rotatably connected to the material holding box 8. A fourth rotating shaft is fixedly arranged on the end of the output end of the second servo motor 9, and a side of the fourth rotating shaft away from the second servo motor 9 is rotatably connected to the inner side of the material holding box 8. A fixed plate 11 and a material stopper 21 are fixedly arranged on the inner side of the material holding box 8, and a rotating plate 10 is rotatably connected to the inner side of the material holding box 8. The outer side of the fourth rotating shaft is fixedly connected to the rotating plate 10, and an inclined plate 13 is fixedly arranged on the inner bottom surface of the material holding box 8. The plate 13 can facilitate the automatic discharge of the tea leaves inside the material box 8 when the rotating plate 10 is opened outward. A spring 24 and a pressure sensor 25 are fixedly arranged on the bottom surface of the fixed plate 11. The control panel 12 is electrically connected to the second servo motor 9 and the pressure sensor 25 respectively. A lifting inclined plate 22 is fixedly arranged on the end of the spring 24 away from the fixed plate 11. The bottom surface of the lifting inclined plate 22 is an inclined surface. The side surface of the lifting inclined plate 22 is slidably connected to the blocking block 21. A guide rod 23 is fixedly arranged on the top surface of the lifting inclined plate 22. A guide groove adapted to the guide rod 23 is arranged on the bottom surface of the fixed plate 11. The guide rod 23 is slidably connected to the fixed plate 11 through the guide groove. The collecting component can collect the tea leaves after transportation, and discharge the tea leaves outward at the same time after the collection is completed, so that the discharged tea leaves can enter the external tea-fixing machine for withering at the same time, so as to avoid the tea leaves entering the tea-fixing machine one by one, resulting in a large difference in the degree of tea-fixing.

[0029] Specifically, the tea leaves transported by the conveyor belt 6 enter the material box 8 from the top of the conveyor belt 6, and the bottom surface of the rotating plate 10 is close to the material box 8 so that the material box 8 collects the tea leaves. When the tea leaves inside the material box 8 begin to contact the lifting inclined plate 22 and continue to accumulate upward, the thrust on the inclined surface of the lifting inclined plate 22 gradually increases, and the thrust pushes the lifting inclined plate 22 to move upward, and the spring 24 is compressed until the lifting inclined plate 22 contacts the pressure sensor 25. The pressure sensor 25 sends an electrical signal to the control panel 12, and the control panel 12 controls the output end of the second servo motor 9 to rotate, thereby driving the rotating plate 10 to move upward. After rotating outward by ninety degrees, the tea leaves are discharged through the gap between the rotating plate 10 and the material containing box 8, and the thrust on the inclined surface of the lifting inclined plate 22 is reduced, so that the spring 24 pushes the lifting inclined plate 22 to move downward until the lifting inclined plate 22 is separated from the pressure sensor 25. The pressure sensor 25 stops sending electrical signals to the control panel 12, and the control panel 12 controls the output end of the second servo motor 9 to rotate inward by ninety degrees. The inclined plate 13 can facilitate the discharge of the tea leaves in the material containing box 8 before the rotating plate 10 rotates back to its original position, and the discharged tea leaves enter the external tea-fixing machine for withering at the same time.

[0030] Specific working principle:

[0031] When the device is in use, the driving motor 4 is operated to drive the first rotating shaft 5 to rotate, the rotation of the first rotating shaft 5 drives the conveyor belt 6 to rotate, the rotation of the conveyor belt 6 drives the second rotating shaft 7 to rotate, the tea leaves are placed on the top surface of the conveyor belt 6, the rotation of the conveyor belt 6 can drive the tea leaves to move, and the tea leaves are transported, the first servo motor 14 is operated to drive the third rotating shaft 15 to rotate, the rotation of the third rotating shaft 15 drives the cam 17 to rotate, the cam 17 rotates and contacts the lifting rod 18 to drive the lifting rod 18 and the lifting plate 20 to move upward along the through hole and the sleeve 19, when the protrusion of the cam 17 rotates to the highest position, the lifting plate 20 continues to move upward due to inertia, the cam 17 disengages from the lifting rod 18, and the lifting plate 20 moves upward along the through hole and the sleeve 19. When the descending plate 20 contacts the conveyor belt 6, it impacts the conveyor belt 6, causing the impacted part of the conveyor belt 6 to fluctuate up and down. After the lifting plate 20 impacts the conveyor belt 6, it moves downward under the influence of gravity until the cam 17 contacts the lifting rod 18 again to drive the lifting rod 18 and the lifting plate 20 to move upward. The cam 17 continues to rotate to make the lifting plate 20 frequently impact the conveyor belt 6, causing the conveyor belt 6 to fluctuate up and down frequently, vibrating the tea leaves, and the screened sand and gravel enters the collection box. The vibration component will not drive the tea leaves to move in a direction perpendicular to the movement of the conveyor belt 6, so that the tea leaves will not accumulate on one side of the top surface of the conveyor belt 6, thereby avoiding affecting the screening effect of the conveyor belt 6 on the tea leaves.

[0032] The tea leaves transported by the conveyor belt 6 enter the material box 8 from the top of the conveyor belt 6, and the bottom surface of the rotating plate 10 is close to the material box 8 so that the material box 8 collects the tea leaves. When the tea leaves in the material box 8 begin to contact the lifting inclined plate 22 and continue to accumulate upward, the thrust on the inclined surface of the lifting inclined plate 22 gradually increases, and the thrust pushes the lifting inclined plate 22 to move upward, and the spring 24 is compressed until the lifting inclined plate 22 contacts the pressure sensor 25. The pressure sensor 25 sends an electrical signal to the control panel 12, and the control panel 12 controls the output end of the second servo motor 9 to rotate, thereby driving the rotating plate 10 to rotate outward by ninety degrees, and the tea leaves pass through the rotating plate 10. The tea leaves are discharged from the gap between the lifting inclined plate 22 and the material holding box 8, and the thrust on the inclined surface of the lifting inclined plate 22 is reduced, so that the spring 24 pushes the lifting inclined plate 22 to move downward until the lifting inclined plate 22 is separated from the pressure sensor 25. The pressure sensor 25 stops sending electrical signals to the control panel 12, and the control panel 12 controls the output end of the second servo motor 9 to rotate in the opposite direction to drive the rotating plate 10 to rotate inward by ninety degrees. The inclined plate 13 can facilitate the discharge of the tea leaves in the material holding box 8 before the rotating plate 10 rotates back to its original position. The discharged tea leaves enter the external tea-withering machine for withering at the same time, so as to avoid the tea leaves entering the withering machine one by one, resulting in a large difference in the degree of tea withering.
