Description

Technical Field

[0001] The utility model belongs to the technical field of drying and screening devices, and particularly relates to a drying and screening device for tea processing. Background Technique

[0002] Tea, commonly known as cha, generally includes the leaves and buds of tea trees. The components of tea include catechins, cholestenone, caffeine, which are beneficial to health. The tea beverages made from tea are one of the three major beverages in the world.

[0003] When operators process tea, they often need to perform drying and screening operations on the tea. At this time, relevant drying and screening devices are required. However, in the actual use process of existing drying and screening devices, generally, operators place the tea inside the drying box and then use a dryer to perform static drying on the tea. However, such drying operations are very inefficient. The accumulation of tea will cause the tea inside to not be fully dried. At the same time, after drying, the operators still need to take out the tea and then transport it to the screening device for screening, resulting in low processing efficiency. Therefore, it needs to be improved. Summary of the Utility Model

[0014] 1. In the present utility model, by providing a vibrating plate, a first spring, a guiding plate, a rectangular plate, and an elliptical block, the operator first starts the hot air blower. The air extraction pipe extracts the external air and converts it into hot air flow, which is then discharged into the interior of the outer shell through the exhaust pipe for drying. At this time, the motor is started. The operation of the motor will cause the rotating shaft to drive the elliptical block to rotate. At this time, the elliptical block will rotate and squeeze the rectangular plate, causing the rectangular plate to drive the vibrating plate to move upward. The vibrating plate will apply a pulling force to the first spring. As the elliptical block rotates, the first spring will cause the vibrating plate to quickly move downward due to the elastic recovery effect, and at this time, the tea leaves can be evenly dried, and at the same time, the effect of integrating drying and sieving is obtained.

When the operator needs to exhaust through the ventilation holes, first pull the pulling plate. The pulling plate will drive the blocking block to move smoothly under the limiting action of the limiting block. The blocking block will simultaneously apply a squeezing force to the second spring. When the blocking block leaves the front surface of the connecting plate, then pull the pulling block. The pulling block will drive the connecting plate and the moving block to move smoothly under the limiting action of the limiting plate. At this time, the moving block will release the sealing effect on the ventilation holes. Description of the Drawings

[0040] The working principle and usage process of the present utility model:

[0041] First, the operator opens the shell cover 17. At this time, the tea leaves can be poured into the interior of the outer shell 1 through the feeding port 16. At this time, the tea leaves will fall onto the top of the vibrating plate 6. Then, the operator pulls the pull plate 24. The pull plate 24 will drive the stopper 23 to move smoothly under the limiting action of the limiting block 25. At this time, the stopper 23 will exert a squeezing force on the second spring 3. At this time, the stopper 23 will leave the front surface of the connecting plate 21. Then, the operator pulls the pull block 22. The pull block 22 will drive the connecting plate 21 and the moving block 19 to move smoothly under the limiting action of the limiting plate 20. At this time, the moving block 19 will release the covering effect on the air vent 18.

[0042] Then, the operator starts the hot air blower 2. The suction pipe 4 will extract the external gas and convert it into hot air flow, which is then discharged into the interior of the outer shell 1 through the exhaust pipe 5. At this time, the tea leaves can be dried. At this time, the hot air flow will be discharged through the air vent 18. Then, the operator starts the motor 11. The operation of the motor 11 will cause the rotating shaft 12 and the elliptical block 13 to rotate simultaneously. At this time, the elliptical block 13 will rotate and squeeze the rectangular plate 10. The rectangular plate 10 will cause the vibrating plate 6 and the guiding plate 9 to move upward simultaneously. At this time, the vibrating plate 6 will simultaneously exert a pulling force on the first spring 8. As the elliptical block 13 rotates, the first spring 8 will cause the vibrating plate 6 to move downward rapidly due to the elastic recovery effect. At this time, the vibrating plate 6 and the mesh holes 7 will cooperate to screen the tea leaves. At this time, the tea leaf powder will fall to the bottom inside the outer shell 1. After the drying operation is completed, the operator opens the movable door 14. At this time, the tea leaf powder can be taken out. Then, the operator opens the rotating door 15. At this time, the dried tea leaves can be taken out.
