When drying tea leaves, the tea leaves are poured into the drying box 1 through the feed port 2 at a uniform speed, so that the tea leaves evenly fall onto the guide plate 7 for continuous drying in the form of vibration pushing, and then the dried tea leaves are circulated and discharged through the discharge port 3.

[0024] The interior of the drying box 1 is provided with a plurality of sets of rotating shaft frames 6 arranged in a symmetrical and staggered manner, and the top ends of the brackets of the two sets of rotating shaft frames 6 facing each other are provided with guide plates 7 in opposite directions. A crankshaft pushing mechanism for driving the guide plates 7 is provided at the bottom of the drying box 1. The crankshaft pushing mechanism comprises a driving shaft 10 installed at the bottom of the drying box 1 and a sway seat 12 installed on the bottom guide plate 7 perpendicular to the direction of the driving shaft 10. An eccentric wheel 11 for supporting the sway seat 12 is provided on the outer side of the shaft of the driving shaft 10, and a driving motor 4 installed on the drying box 1 is provided at one end of the shaft of the driving shaft 10. By controlling the operation of the driving motor 4, the driving shaft 10 is driven to rotate, and then the eccentric wheel 11 is driven to rotate. The eccentric swing of the eccentric wheel 11 is utilized to cyclically support the sway seat 12, and the guide plate 7 is pushed to cyclically mechanically shake, so that the tea leaves on the plate surface are mechanically vibrated and dropped, so that the tea leaves can be kept dynamically guided and dried while ensuring the comprehensiveness of the tea leaves drying.

[0025] The two groups of guide plates 7 adjacent to each other are connected by an arm force connecting rod 8. The rear end of the bracket of the rotating shaft frame 6 is provided with a rotating shaft connected to the drying box 1 for rotation, and the upper end of the bracket of the rotating shaft frame 6 is symmetrically provided with a vibration spring 9 connected to the wall of the drying box 1.

By controlling the combined operation of the blower fan 51 and the heating coil 53, the external normal temperature air is driven by the wind of the blower fan 51, and after being heated by the heating coil 53, it is blown into the drying box 1 to perform a drying process on the tea leaves mechanically vibrated and guided in the drying box 1.

[0028] The working principle of the utility model is as follows: when drying tea leaves, the tea leaves are poured into the drying box 1 through the feed port 2 at a uniform speed, so that the tea leaves fall evenly onto the guide plate 7. At this time, the driving motor 4 is controlled to work, driving the driving shaft 10 and the eccentric wheel 11 to rotate in combination, and the eccentric swing of the eccentric wheel 11 is utilized to cyclically support the eccentric swing seat 12, so as to push the guide plate 7 at the bottom to cyclically mechanically shake, and the multiple groups of guide plates 7 are connected by the arm force connecting rod 8 to maintain an integrated force mode, and then the rotation The elastic deflection combination of the shaft frame 6 and the vibration spring 9 supports the guide plate 7, so that the multiple groups of guide plates 7 are subjected to reciprocating supporting force and synchronous mechanical vibration, so that the tea leaves on the plate surface are cyclically vibrated and dropped, and then the hot air from the hot fan mechanism 5 is blown to dynamically dry the cyclically dropped tea leaves, and the dried tea leaves are cyclically discharged through the discharge port 3. The staff only needs to add cyclic material to the tea leaves to carry out a continuous and uninterrupted drying process. The drying efficiency is more efficient and the intensity of human control is lower.
