Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and more specifically to a tea turning device. Background Technology

[0002] Tea leaves refer to the leaves and buds of the tea plant. Generally, it refers to the leaves of the evergreen shrub tea plant, which can be used to brew tea, and the beverage made from these leaves. Tea plantations thrive in hilly terrain with good drainage, abundant rainfall, small annual temperature differences, large diurnal temperature differences, a long frost-free period, and good sunlight. These climatic conditions are suitable for the growth of various types of tea trees, especially large-leaf tea varieties. Tea production requires turning, fixing, and drying the tea leaves.

[0003] Currently, when processing tea leaves for fixing and drying, the tea leaves are usually placed inside a rotating drum. While the drum is being driven to rotate, hot air is introduced into the drum to contact the tea leaves. Then, the hot and humid air is discharged from the drum, thus achieving the purpose of heating and drying the tea leaves. However, because the hot and humid air is directly discharged into the external environment, heat energy is wasted, which is difficult to meet the requirements of green processing.

[0004] In view of this, the present invention proposes a tea leaf turning device to solve this problem. Utility Model Content

[0008] Furthermore, a control panel is fixedly mounted on the surface of the mounting bracket, and the control panel is electrically connected to an external power source via wires.

[0010] Furthermore, the drive turning assembly includes a geared motor fixedly mounted on the surface of the mounting cylinder, a drive gear fixedly mounted on the output shaft surface of the geared motor, and an external gear ring fixedly mounted on the surface of the rotating cylinder, with the drive gear and the external gear ring meshing with each other.

[0012] Furthermore, a dust filter is provided at the air inlet end of the air inlet pipe.

[0014] Furthermore, a spiral guide plate is fixedly installed on the inner wall of the rotating cylinder, and the spiral guide plate is used to guide and turn the tea leaves.

[0015] As a further description of the above technical solution: by setting a spiral guide plate, the tea leaves can be guided and turned, so that the tea leaves are heated evenly inside the rotating drum, thereby improving the drying and fixing effect of the device.

[0016] Furthermore, a heat-conducting protrusion ring is fixedly installed on the inner wall of the connecting ring pipe, and several heat-conducting pillars are evenly embedded in the inner wall of the air inlet pipe. The heat-conducting protrusion ring and the heat-conducting pillars are both made of copper.

[0017] As a further description of the above technical solution: by setting up heat-conducting protrusions and heat-conducting columns, the heat exchange area between the connecting ring pipe and the inner wall of the air inlet pipe is increased, thereby improving the heat exchange efficiency.

The tea leaves to be processed are placed inside the rotating drum, and the rotating drum is driven by the turning component to rotate, achieving the purpose of turning the tea leaves during rotation. Hot air is driven into the heat-conducting chamber by a hot air blower, and then the hot air enters the rotating drum through the heat-conducting holes to contact the tea leaves, achieving the purpose of drying and fixing the tea leaves. During this process, the hot and humid air is discharged from the feed inlet and contacts the connecting ring pipe. The heat-conducting liquid inside the connecting ring pipe is heated, and then the circulation pump is started. The circulation pump drives the heat-conducting liquid to circulate between the preheating jacket and the connecting ring pipe, achieving the purpose of preheating the air inside the preheating jacket. The preheated air enters the hot air blower through the air inlet pipe, reducing the waste of heat energy and reducing the power of the hot air blower, thereby increasing the practicality of the device and meeting the needs of green processing.

[0022] 2. Compared with existing technologies, this tea-turning device, through the addition of a control panel, allows operators to easily control the hot air blower, circulating pump, and geared motor, thereby increasing the device's convenience and improving its working efficiency. The drive-turning assembly, based on the meshing of the drive gear and external gear ring, drives the rotating drum smoothly. The dust filter prevents dust from contaminating the tea leaves. The spiral guide plate guides the tea leaves, ensuring even heating within the rotating drum and improving the drying and fixing effect. The heat-conducting protrusion ring and heat-conducting column increase the heat exchange area between the connecting ring pipe and the inner wall of the air inlet pipe, improving heat exchange efficiency. The tilting shaft and deflection assembly, driven by the extension and retraction of the hydraulic rod, move the rack. The meshing of the rack and gear disc allows for adjustment of the tilting angle of the tilting shaft and rotating drum, facilitating the discharge of tea leaves from the rotating drum and increasing the device's flexibility.

[0030] By setting up the control panel 13, staff can easily control the opening and closing of various electrical appliances, thereby increasing the convenience of the device and improving its working efficiency.

[0031] The inner wall of the mounting frame 1 is provided with a mounting cylinder 2. A slag discharge port is reserved on the bottom side of the mounting cylinder 2, and a gate 26 is provided on the surface of the slag discharge port. A rotating cylinder 3 is rotatably connected to the inner wall of the mounting cylinder 2. A material port is provided on the front of the rotating cylinder 3.

The drive gear 15 and the external gear ring 16 mesh with each other.

[0033] By setting up a drive-turning component, based on the meshing of the drive gear 15 and the external gear ring 16, the rotating drum 3 can be driven to rotate smoothly under the driving effect of the reduction motor 14.

[0034] A heat-conducting cavity 4 is reserved between the mounting cylinder 2 and the rotating cylinder 3. Several heat-conducting holes 5 are evenly opened on the outer wall of the rotating cylinder 3 corresponding to the heat-conducting cavity 4.

The tea to be processed is placed inside the rotating drum 3, and the rotating drum 3 is driven to rotate by the driving turning component. During the rotation, the purpose of turning the tea is achieved.

[0043] A heat-conducting protrusion ring 19 is fixedly installed on the inner wall of the connecting ring pipe 9, and several heat-conducting pillars 20 are evenly embedded in the inner wall of the air inlet pipe 7. The heat-conducting protrusion ring 19 and the heat-conducting pillars 20 are both made of copper.

[0044] It is worth noting that by setting the heat-conducting protrusion ring 19 and the heat-conducting column 20, the heat exchange area of ​​the inner wall of the connecting ring pipe 9 and the air inlet pipe 7 is increased, thereby improving the heat exchange efficiency.

[0045] A flip shaft 21 is fixedly installed on the outer wall of the mounting cylinder 2. The flip shaft 21 is rotatably connected to the mounting frame 1. A deflection component is provided on the surface of the mounting frame 1 corresponding to the flip shaft 21.

[0046] The deflection assembly includes a drive box 22 fixedly mounted on the surface of the mounting bracket 1, a tilting shaft 21 rotatably connected to the drive box 22, a hydraulic rod 23 embedded in the surface of the drive box 22, the telescopic end of the hydraulic rod 23 extending into the interior of the drive box 22 and fixedly mounted with a rack 24, and a gear plate 25 fixedly mounted on the surface of the tilting shaft 21, with the rack 24 and the gear plate 25 meshing with each other.

[0047] It is worth noting that by setting up the flip shaft 21 and the deflection assembly, the rack 24 can be driven to move under the extension and retraction effect of the hydraulic rod 23. Based on the meshing of the rack 24 and the toothed disc 25, the tilt angle of the flip shaft 21 and the rotating cylinder 3 can be adjusted, which makes it easier to discharge the tea leaves from the inside of the rotating cylinder 3 after processing, thus increasing the flexibility of the device.
