In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model. Example

[0024] like Figure 1-5 As shown, it is the first embodiment of the utility model, which provides a tea drying device, including a drying box 1, a movable door 2 is hinged on the front of the drying box 1, a hot air blower 3 is fixedly connected to the top of the drying box 1, ventilation holes 4 are opened on both sides of the drying box 1, and the inner cavity of the ventilation holes 4 is fixedly connected to a dustproof net, the upper and lower ends of the inner cavity of the drying box 1 are detachably connected to a placement box 5, the inner cavity of the placement box 5 is fixedly connected to a screen 6, a slag discharge port 7 is opened on the front of the placement box 5, and a stirring mechanism 8 is provided in the inner cavity of the drying box 1;

[0025] The stirring mechanism 8 includes a support plate 801, which is arranged in the inner cavity of the drying box 1. The number of support plates 801 is twelve. The front and rear ends of the bottom of the support plates 801 are movably connected to stirring plates 802 through movable pins. Both sides of the support plates 801 are fixedly connected to limit frames 803, and the two limit frames 803 extend in opposite directions.

[0026] like Figure 1-5 As shown, the drying box 1 and the movable door 2 are used to provide a closed drying space for the tea leaves, which can reduce heat loss to a certain extent. The hot air blower 3 is used to transport hot air to the interior of the drying box 1 so as to dry the tea leaves. The vent 4 is used for air circulation. The tea leaves to be dried are placed on the top of the placement box 5. During the operation of the stirring mechanism 8, the tea leaves on the top of the placement box 5 can be turned over, so that the tea leaves stacked at different positions and heights can be continuously changed in position, so that the tea leaves can be dried more evenly and fully. Example

[0027] Reference Figure 3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0028] In this embodiment, a movable column 804 is provided on the right side of the inner cavity of the drying box 1, and the number of the movable columns 804 is four. The support sheet 801 is fixedly connected to the surface of the movable column 804, and the inner cavity of the movable column 804 is slidably connected with a positioning column 805. The left end of the positioning column 805 extends to the outside of the movable column 804 and is fixedly connected to the inner wall of the drying box 1.

[0029] The upper and lower ends of the right side of the drying box 1 are fixedly connected to an electric push rod 806, and the output end of the electric push rod 806 is fixedly connected to a connecting plate 807. The left end of the movable column 804 passes through the outside of the drying box 1 and is fixedly connected to the connecting plate 807. The movable column 804 is slidably connected to the inner wall of the drying box 1.

[0030] like Figure 3 As shown, when the electric push rod 806 reciprocates and retracts, it can cooperate with the connecting plate 807 to pull the movable column 804 to move back and forth left and right inside the drying box 1. During the movement of the movable column 804, the limit frame 803 can support and limit the limit frame 803 to ensure its stability during the movement. The movable column 804 can drive the support sheet 801 to move. When moving to the right, the rear end stirring plate 802 cannot be turned to the left due to the resistance of the tea leaves under the action of the limit frame 803 on the left side. Therefore, at this time, the rear end stirring plate 802 is used to turn the tea leaves over, while the front end limit frame 803 is used to limit the position of the limit frame 803 on the left side. 03 will flip to the left due to the resistance of the tea leaves and will not participate in the turning over of the tea leaves. When moving to the left, the front stirring plate 802 will be limited by the right limit frame 803 and cannot flip to the right due to the resistance of the tea leaves. Therefore, at this time, the front stirring plate 802 will flip the tea leaves, and the rear limit frame 803 will flip to the right due to the resistance of the tea leaves and will not participate in the turning over of the tea leaves. When the electric push rod 806 reciprocates and extends, the two stirring plates 802 can reciprocate to cooperate with each other to fully turn the tea leaves over, so that tea leaves at different positions and heights can fully contact with the hot air. Example

[0031] Reference Figure 2 and 5 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0032] In this embodiment, the upper and lower ends of the back side of the inner cavity of the drying box 1 are fixedly connected with a support frame 9, the rear end of the placement box 5 extends to the top of the support frame 9, and the two sides of the inner cavity of the drying box 1 are fixedly connected with mounting plates 10, and the number of mounting plates 10 is four.

[0033] Hollow plates 11 are fixedly connected to both sides of the bottom of the placement box 5, and an insert plate 12 is slidably connected to the inner cavity of the hollow plate 11. The front end of the insert plate 12 extends to the inner cavity of the mounting plate 10 and is detachably connected to the inner cavity of the mounting plate 10.

[0034] A compression spring 13 is fixedly connected to the back of the insertion plate 12, and the rear end of the compression spring 13 is fixedly connected to the inner wall of the hollow plate 11. A through groove 14 is provided at the bottom of the hollow plate 11, and a push block 15 is slidably connected to the inner cavity of the through groove 14. The top of the push block 15 extends to the inner cavity of the hollow plate 11 and is fixedly connected to the bottom of the insertion plate 12.

[0035] like Figure 2 and 5 As shown, the support frame 9 is used to support the rear end of the placement box 5, and the mounting plate 10, the hollow plate 11 and the compression spring 13 cooperate to support the front end of the placement box 5, thereby improving the stability of the placement box 5 when in use. By pushing the push block 15, the insertion plate 12 can be driven to move in the inner cavity of the hollow plate 11. When moving, the insertion plate 12 will squeeze the compression spring 13 and cause the compression spring 13 to deform. After the insertion plate 12 is removed from the inside of the mounting plate 10, the placement box 5 can be disassembled.

[0036] When in use, first place the tea leaves on the top of the placement box 5, then open the movable door 2, and insert the rear end of the placement box 5 obliquely into the top of the support frame 9 in a way of holding with both hands, then push the push block 15 backwards with the thumb, and the push block 15 drives the insertion plate 12 to move backwards inside the hollow plate 11. When the insertion plate 12 moves, it squeezes the compression spring 13 and causes the compression spring 13 to deform, and then the placement box 5 is straightened. After straightening, the push block 15 is released, and the pressure on the compression spring 13 disappears and resets. The reset elastic force of the compression spring 13 drives the insertion plate 12 to move backwards. After the installation is completed, the movable door 2 is closed and the hot air blower 3 and the electric push rod 806 are turned on. When the hot air blower 3 is running, hot air can be delivered to the inside of the insertion plate 12 to dry the tea leaves. When the electric push rod 806 reciprocates and retracts, it can cooperate with the connecting plate 807 to pull the movable column 804 to move back and forth inside the drying box 1. The movable column 804 can drive the supporting sheet 801 to move. When moving to the right, the rear end stirring plate 802 is limited to the left side. The front end limit frame 803 will be limited by the right limit frame 803, and cannot be turned over to the right due to the resistance of the tea leaves. Therefore, the front end stirring plate 802 will turn the tea leaves over, while the front end limit frame 803 will turn over to the left due to the resistance of the tea leaves, and will not participate in the turning over of the tea leaves. When the push rod 806 reciprocates and retracts, the two stirring plates 802 can cooperate with each other to fully turn the tea leaves over, so that tea leaves at different positions and heights can fully contact with the hot air. While drying, the screen 6 can also screen the residues in the tea leaves, and the screened residues are stored under the placement box 5. After drying, the placement box 5 is taken out by the above operation. After taking it out, the tea leaves are poured out by tilting backwards. After the tea leaves are poured out, the residues are poured out through the residue discharge port 7 by tilting forwards, so as to carry out the drying operation of the tea leaves.
