Detailed Embodiment

[0017] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a tea dryer with tea debris screening, including a drying box body 1, a perforated screening cylinder 8, a fixed motor 14 and a moving square frame 18. A tea debris discharge hopper 2 is installed at the lower end inside the drying box body 1, and a servo motor 6 is installed at the right end of the drying box body 1. The left and right ends inside the drying box body 1 are installed with side plates 7 through bearings. The perforated screening cylinder 8 is horizontally installed between the two side plates 7. A moving slot 10 is opened at the upper end of the drying box body 1. A first touch switch 11 and a second touch switch 12 are respectively installed at the left and right ends inside the moving slot 10. Side plates 13 are installed on both the left and right sides at the upper end of the moving slot 10. A fixed motor 14 is installed at the left end of the left side plate 13. A lead screw 15 is installed between the two side plates 13 through bearings. A nut 16 is sleeved on the circumferential side of the lead screw 15. The moving square frame 18 is slidably located inside the moving slot 10. A dust-proof net 19 is installed at the upper end inside the moving square frame 18, and a blower 20 is installed below the dust-proof net 19. A fan 21 is installed at the shaft end of the blower 20. A serpentine heating wire 22 and a flow equalizing air plate 23 are horizontally installed at the lower end inside the moving square frame 18. This design solves the problems that the original dryer directly dries the tea, the drying effect is average and not uniform enough, and it is relatively troublesome to manually clean the tea debris.

[0019] As the first embodiment of the present utility model: A tea debris collection box 3 is placed below the tea debris discharge hopper 2. By adding the tea debris collection box 3, when the tea debris is discharged through the perforated screening cylinder 8 and the tea debris discharge hopper 2, it can be collected. An installation frame 4 is installed at the front end of the drying box body 1, and a movable shutter 5 is slidably arranged inside the installation frame 4. By adding the movable shutter 5, it is convenient to open the inside of the drying box body 1 to observe the perforated screening cylinder 8.

[0020] The shaft end of the servo motor 6 is connected to the right side plate 7, and the shaft end of the fixed motor 14 is connected to the lead screw 15. By adding the servo motor 6, the right side plate 7 can be driven to rotate in place, and the fixed motor 14 can drive the lead screw 15 to rotate in place. A threaded cover 9 is installed at the upper end of the perforated screening cylinder 8. By adding the threaded cover 9, it is convenient to open the inside of the perforated screening cylinder 8 to take and place the tea inside. The moving square frame 18 is connected to the nut 16 through two inclined connecting plates 17. By adding the two inclined connecting plates 17, when the nut 16 is driven to move, the moving square frame 18 can be driven to move accordingly.

[0021] As the second embodiment of the present utility model: When the device is in working use, the servo motor 6 is started. The servo motor 6 can drive the side plate 7 and the perforated sieving cylinder 8 to rotate. When the perforated sieving cylinder 8 rotates, the tea leaves therein will be driven to turn over, and the tea leaf debris will pass through the holes of the perforated sieving cylinder 8 and fall to the tea leaf debris discharge hopper 2, and then fall into the tea leaf debris collection box 3 from the tea leaf debris discharge hopper 2 for subsequent processing by the staff. At the same time, the fixed motor 14 is started. The shaft end of the fixed motor 14 drives the lead screw 15 to rotate forward. The nut 16 will move to the right on the annular side of the lead screw 15, and drive the moving square frame 18 to move to the right in the moving notch 10 through the two inclined connecting plates 17. As a result, the dust-proof net 19, the fan 20, the fan 21, the serpentine heating wire 22 and the flow equalizing air plate 23 are driven to move accordingly. At the same time, the fan 20 and the serpentine heating wire 22 are started. The fan 20 drives the fan 21 to rotate. The rotating fan 21 can take away the heat at the serpentine heating wire 22 and blow it towards the rotating perforated sieving cylinder 8, so as to dry the flipped tea leaves. When the moving square frame 18 touches the second touch switch 12, the second touch switch 12 controls the shaft end of the fixed motor 14 to rotate in the reverse direction, so that the lead screw 15 rotates in reverse accordingly. The nut 16 will move to the left on the annular side of the lead screw 15, and then drive the dust-proof net 19, the fan 20, the fan 21, the serpentine heating wire 22 and the flow equalizing air plate 23 to move to the left until the moving square frame 18 touches the first touch switch 11. The first touch switch 11 re-controls the shaft end of the fixed motor 14 to rotate forward again. Repeating like this, the moving fan 20 can evenly dry the flipped tea leaves.
