[0025] Please refer to Figures 1-5In the embodiment, the tea leaves are gently turned over and are not easily broken. The lower ends of the two support plates 2 are provided with three cavity plates 13. The lower ends of the cavity plates 13 are connected with air inlet joints 14. The connecting plates 4 are connected with a driving assembly. The driving assembly is used to drive the connecting plates 4 to move up and down alternately. The connecting plates 4 are used to drive the turning assembly to move. The turning assembly is used to turn over the tea leaves.
[0026] In the embodiment, the air inlet joints 14 are used to connect external hot air pipes to guide dry hot air into the cavity plates 13. The cavity plates 13 are used as air collecting and uniform flow cavities of the hot air to uniformly distribute the hot air. The driving assembly drives the cam 9 and the connecting rod to move through the motor 12 to convert the rotary motion into linear reciprocating motion to drive the two connecting plates 4 to move up and down alternately. The movement of the connecting plates 4 drives the turning assembly to make a seesaw action as a whole to realize the periodic lifting and lowering of the tea leaves. The turning plate in the turning assembly carries the tea leaves. When one side is lifted, the tea leaves naturally slide down to complete turning over under the action of gravity. The air holes 7 distributed on the cavity plates 13 allow the hot air to penetrate the tea leaf layer from the bottom to continuously and efficiently dry the tea leaves during the turning process. The whole structure works cooperatively to realize the gentle turning of the tea leaves and the uniform hot air drying to effectively reduce the broken tea and maintain the integrity of the tea leaves.
[0027] It should be noted that the two motors 12 are provided with different powers to realize the up and down movement of the two connecting plates 4 at different frequencies. Two independently controlled motors 12 are used. By adjusting the power or speed, the movement frequency and amplitude of the two connecting plates 4 can be conveniently adjusted to adapt to the drying process requirements of different types and different moisture content of tea leaves with high flexibility.
[0028] Please refer to Figures 1-5 In the embodiment, the driving assembly includes a fixed plate 11 arranged on the ground, two motors 12 mounted on the fixed plate 11, a fixed rod 10 mounted on the output end of the motor 12, a cam 9 connected to the other end of the fixed rod 10, and a transmission plate 8 rotatably connected to the cam 9. The upper end of the transmission plate 8 is rotatably connected to the surface of the connecting plate 4. The motor 12 is used to drive the cam 9 to rotate. The transmission plate 8 is used to convert the rotary motion of the cam 9 into up and down motion. The sliding end of the connecting block 5 is slidably connected to the sliding groove on the inner surface of the connecting plate 4. The outer surface of the connecting plate 4 is provided with a sliding groove. The sliding groove on the outer surface of the connecting plate 4 is used to slidably connect the mounting frame 1. A plurality of connecting blocks 5 are arranged between the two connecting plates 4 in pairs and alternately in the front and back directions. The front end of part of the connecting blocks 5 is fixed to the front connecting plate 4. The rear end is slidably connected to the rear connecting plate 4. The rear end of another part of the connecting blocks 5 adjacent to the part is fixed to the rear connecting plate 4. The front end is slidably connected to the front connecting plate 4. The connecting blocks 5 form an alternating reverse connection layout.
[0029] In the embodiment, the fixed plate 11 is used to fix the support motor 12, ensuring that the driving part is stably installed on the ground. The motor 12 provides a power source to drive the fixed rod 10 to rotate through an output shaft. The fixed rod 10 is connected to the output end of the motor 12 and the cam 9 to transfer the rotary motion. The cam 9 converts the continuous rotary motion of the motor 12 into a specific regular reciprocating swing. One end of the transmission plate 8 is connected to the cam 9, and the other end is connected to the plate 4, converting the swing of the cam 9 into the up-down linear motion of the connecting plate 4. The connecting plate 4 receives the thrust of the transmission plate 8 to realize the up-down movement and drive the turnover assembly to act. The sliding block is used to realize the smooth movement of the sliding end of the connecting block 5, reducing the friction resistance. The sliding groove provides a guide rail for the sliding block to constrain the movement direction of the connecting block 5. The connecting block 5 is fixed to one connecting plate 4 at the front end or rear end and is slidably connected to the other connecting plate 4 at the other end, so as to alternately and reversely connect the two connecting plates 4, transfer the motion and support the turnover plate. The turnover plate is used to carry tea leaves and is lifted and lowered under the driving of the connecting plate 4 to complete the turnover action.
[0030] It should be noted that the turnover assembly includes a plurality of connecting blocks 5 fixed to the inner side of the connecting plate 4 and an up-down turnover plate 6 arranged at the upper end of the connecting block 5. The surface of the connecting block 5 is provided with air holes 7. The up-down turnover plate 6 is mainly used to place and support tea leaves. The air holes 7 allow hot air to enter the tea leaf placement area from the bottom. The air inlet connector 14 is used to be connected with the drying machine pipeline outside. The air inlet connector 14 receives the drying gas into the cavity plate 13. The drying gas enters the tea leaf placement area through the air holes 7.
[0031] The working principle of the above embodiment is as follows:
[0032] In use, the drying hot air of the external hot air pipeline enters the cavity plate 13 through the air inlet connector 14. The hot air is uniformly distributed in the cavity plate 13 and penetrates the tea leaf layer through the air holes 7 on the surface of the connecting block 5 to heat and dry the tea leaves. At the same time, the two motors 12 are started. The motor 12 drives the fixed rod 10 to rotate through the output shaft. The fixed rod 10 drives the cam 9 to rotate. The rotary motion of the cam 9 is converted into up-down reciprocating motion through the transmission plate 8. The transmission plate 8 pushes the connecting plate 4 to slide up and down in the sliding groove of the installation frame 1. Due to the different powers of the two motors 12, the two connecting plates 4 move alternately with different frequencies, one rising and one falling. The movement of the connecting plate 4 drives the connecting block 5 inside and the turnover plate at the upper end to act. Part of the connecting block 5 is fixed at the front end and slides at the rear end, and the other part is fixed at the rear end and slides at the front end, forming an alternating and reverse layout, so that the turnover plate as a whole presents a periodic seesaw type lifting and lowering. When one side of the turnover plate is lifted, the tea leaves on it naturally slide and roll under the action of gravity to complete the turnover. The turnover and hot air penetration cooperate to realize the soft turnover and uniform and efficient drying of the tea leaves.
