[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4This utility model discloses a drawer-type temperature-controlled tea charcoal roasting machine, comprising: a body 1, a first cavity 3 inside the body 1, a motor 2 fixedly connected to the upper surface of the body 1, a rotating shaft 5 fixedly connected to the output end of the motor 2, a turntable 6 fixedly connected to the lower surface of the rotating shaft 5, the upper surface of the turntable 6 being rotatably connected to the body 1, a fixing rod 7 fixedly connected to the top inner wall of the first cavity 3, a moving rod 8 slidably connected to the inner surface of the fixing rod 7, a fixing ring 9 fixedly connected to the side surface of the moving rod 8, a fixing groove 10 inside the fixing ring 9, and a shaft inside the fixing groove 10. The upper surface of bearing 11 is fixedly connected to turntable 6. The lower surface of moving rod 8 is fixedly connected to connecting block 12. The lower surface of connecting block 12 is fixedly connected to moving frame 13. The lower surface of moving frame 13 is fixedly connected to moving wheel 14. When starting motor 2, rotating shaft 5 and turntable 6 are driven to rotate, the rotation of turntable 6 causes bearing 11 to move back and forth in fixed groove 10, causing moving rod 8 to move left and right under the action of fixed rod 7, thereby driving connecting block 12, moving frame 13, fixed plate 15 and tea placing tray 18 to move left and right. Moving wheel 14 makes moving frame 13 move more stably.

[0027] A fixed plate 15 is fixedly connected to the inner surface of the movable frame 13. A placement groove 16 is provided on the inner surface of the fixed plate 15. A tea placement tray 18 is provided on the inner surface of the placement groove 16. The tea placement tray 18 can be placed in the placement groove 16. When it is necessary to remove the tea placement tray 18, the operator can lift the tea placement tray 18 with one hand and move it upwards to remove the tea placement tray 18 from the placement groove 16. The fixed plate 15 is provided with a through hole 17 inside, which is designed to facilitate ventilation and drying. The tea placement tray 18 is provided with a first air inlet 19 inside. A partition 20 is fixedly connected to the bottom inner wall of the tea placement tray 18. A second air inlet 21 is provided inside the partition 20. There are multiple partitions 20. The partitions 20 separate the tea in the tea placement tray 18 to prevent the tea from gathering to one side during reciprocating movement.

[0028] The machine body 1 has a second cavity 4 inside, and a charcoal cylinder 22 is installed on the bottom inner wall of the second cavity 4. The machine body 1 has multiple air inlet slots 23, which are linearly distributed. A cylinder 24 is fixedly connected to the right surface of the machine body 1, and an adjustment plate 25 is fixedly connected to the output end of the cylinder 24. The top inner wall of the second cavity 4 is slidably connected to the adjustment plate 25. By starting the cylinder 24, the adjustment plate 25 can be moved, which can adjust the amount of hot air entering the first cavity 3, thereby adjusting the temperature. A temperature sensor 26 is fixedly connected to the top inner wall of the first cavity 3, which can measure the temperature inside the first cavity 3. An air inlet pipe 27 is fixedly connected to the left surface of the machine body 1, and a one-way valve is installed inside the air inlet pipe 27. An air outlet pipe 28 is fixedly connected to the upper surface of the machine body 1. Air is supplied to the machine body 1 through the air inlet pipe 27. The one-way valve is designed to prevent hot air from escaping from the air inlet pipe 27. The dried hot air in the machine body 1 is discharged through the air outlet pipe 28.

[0029] Working principle: Before drying, charcoal is added to the charcoal cylinder 22. The tea leaves to be dried are placed in the tea tray 18. Multiple tea trays 18 are placed on the placement trough 16. The sliding door is closed, and the motor 2 is started to drive the rotating shaft 5 and the turntable 6 to rotate. The rotation of the turntable 6 drives the bearing 11 to move back and forth in the fixed groove 10. The moving rod 8 moves left and right under the action of the fixed rod 7, which in turn drives the connecting block 12, the moving frame 13, the fixed plate 15, and the tea tray 18 to move left and right, thus accelerating the air flow inside the first cavity 3. The moving wheel 14 makes the moving frame 13 move more stably. The partition 20 separates the tea leaves in the tea tray 18 to prevent the tea leaves from gathering to one side during the reciprocating movement. This structure accelerates the flow and exchange of hot air inside the machine body 1, thereby reducing the roasting time of a single batch of tea leaves, thus increasing the output per unit time, and preventing the tea leaves from piling up or shifting to one side during the reciprocating movement.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
