[0002] Most of the existing tea drying equipment is arranged in layers, which can spread the tea evenly and dry it quickly. For example, the authorization announcement number CN215724821U discloses a layered drying device for tea processing. When the layered drying device is in use, the tea is in the process of drying and the drying rack is in the process of rotating. The first triangular block installed at the bottom end of the drying rack and the second triangular block installed at the bottom of the dryer are abutted against each other, so that the first triangular block moves upward under the thrust of the second triangular block, so that the top plate installed on one side of the fixed rod vibrates the sieve plate, so that the tea inside the sieve plate is turned over, so that the tea as a whole is evenly heated, thereby improving the drying efficiency of the tea.

[0003] The existing tea drying equipment is to set a multi-layer placement rack in the drying box, and place multiple mesh shells for holding tea leaves on the multi-layer placement rack. As in the above-mentioned prior art, during the drying process, if the movement of the multi-layer placement rack is controlled, the tea leaves in the mesh shells will be piled up, which will easily cause uneven drying.

When the placement rack 2 is pushed into the drying box 1, the third arc-shaped protrusion 37 is squeezed by the support rod 4 to control the clamping plate 17 to move downward, thereby fixing the mesh shell 5 to prevent the mesh shell 5 from moving when the placement rack 2 is pushed into the drying box 1.

[0034] As a further technical solution of the present invention, a push rod 12 is arranged between the connecting rod 14 and the vertical rod 13, and the push rod 12 is rotatably connected to the vertical rod 13. After the mesh shell 5 is placed and before it is pushed into the drying box 1, by pressing the push rod 12, the L-shaped plug 23 and the card plate 17 can be controlled to move downward at the same time, and the second support frame 6 and the mesh shell 5 can be fixed respectively. If the tea leaves need to be turned over, before the rotating rod 18 is rotated, the push rod 12 is rotated and then pressed to only control the card plate 17 to move downward. After the mesh shell 5 is fixed, the rotating rod 18 is rotated.

[0038] Then, the push rod 12 is pressed to simultaneously control the vertical rod 13 and the connecting rod 14 to move downward, the vertical rod 13 drives the L-shaped plug rod 23 and the second arc-shaped protrusion 20 to move downward, the second spring 21 is squeezed, the L-shaped plug rod 23 moves downward and connects with the through hole 26 to limit the second support frame 6, the connecting rod 14 drives the collar 16 to move downward through the connecting block 36, the collar 16 drives the card plate 17 to move downward to limit the mesh housing 5, the connecting rod 14 also drives the third arc-shaped protrusion 37 to move downward, and the third spring 22 is squeezed;

[0039] The support rod 4 continues to slide into the opening 11, squeezing the second arc-shaped protrusion 20 and the third arc-shaped protrusion 37, and limiting the L-shaped plug rod 23 and the card plate 17;

[0040] Then the drying box 1 is sealed to dry the tea leaves. When the tea leaves need to be turned over during the drying process, the placement rack 2 is moved out of the drying box 1. When moving out, the support rod 4 releases the limit of the first arc-shaped protrusion 29, the second arc-shaped protrusion 20 and the third arc-shaped protrusion 37, the first arc-shaped protrusion 29 moves up, the sawtooth plate 30 first controls the rotation of the shaft 33, and then the plug block 31 is connected with the slot 32;

[0041] After the placement rack 2 is moved out, the second arc-shaped protrusion 20 is released from the limit and moves upward, driving the L-shaped insertion rod 23 to move upward and disengage from the through hole 26, and the push rod 12 is rotated and then pressed to control only the card plate 17 to move downward. After the mesh shell 5 is fixed, any second support rack 6 can be moved to drive the rotating rod 18 to rotate, so that the multiple first support racks 3 and the second support racks 6 are misaligned, so that there is a large space between the multiple mesh shells 5 for turning the tea leaves, and there is no need to remove the multiple mesh shells 5 for turning;

[0042] After the flipping is completed, any one of the second support frames 6 is moved to reset, and when the limiting block 15 abuts against the limiting plate 34 , the through hole 26 just corresponds to the position of the L-shaped insertion rod 23 .

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art that the features thereof are equivalently replaced.
