Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea drying machine. Background Technology

[0002] Drying equipment is a device that removes moisture from materials through heating and evaporation, keeping the materials dry. It is widely used in various production processes. Tea is a popular product, and drying is an essential step in tea processing. Drying equipment can remove some of the moisture from tea leaves, controlling the moisture content within a certain range for easy storage.

[0003] In existing tea drying devices, the tea leaves pile up in one place during drying, which is not conducive to the evaporation of moisture from the tea leaves and slows down the drying efficiency. During the turning process, the tea leaves in the drying device are subjected to a large force of vibration and collision, which easily causes the tea leaves to break and produce a lot of debris, affecting the quality of the dried tea leaves. Therefore, a tea drying machine is proposed to solve the above problems. Utility Model Content

[0004] This utility model provides a tea drying machine, including a drying chamber, a lifting frame, and a shaking mechanism. The lifting frame is slidably disposed inside the drying chamber, and the shaking mechanism is located below the lifting frame, driving it to slide up and down continuously. It also includes multiple placement frames, multiple guide hoppers, a discharge pipe, and a collection box. The multiple placement frames are spaced apart and connected between the left and right walls of the lifting frame. A leveling component is disposed above each of the multiple placement frames. The multiple guide hoppers are respectively connected to the bottom ends of the multiple placement frames and extend to the rear side of the lifting frame. A lifting mechanism is disposed inside the drying chamber to drive the multiple sets of leveling components to rise and fall. The collection box is connected to the bottom wall of the drying chamber. The discharge pipe is connected to the rear side of the lifting frame and communicates with the multiple guide hoppers. The bottom end of the discharge pipe extends into the collection box.

[0005] Preferably, the leveling assembly includes a drive frame, a first motor, a threaded rod, a moving plate, and multiple pusher teeth. The drive frame is located directly above the placement frame. The first motor is located on the left side of the drive frame. One end of the threaded rod is coaxially connected to the output shaft of the first motor, and the other end is rotatably connected to the right side wall of the drive frame. The moving plate is threadedly connected to the threaded rod and extends to the bottom of the drive frame. The multiple pusher teeth are all connected to the bottom end of the moving plate.

[0006] Preferably, the lifting mechanism includes two hydraulic cylinders and two connecting plates. The hydraulic cylinders are located at the top of the drying chamber, and the telescopic rod is connected to the drive frame above. The two connecting plates are connected between two adjacent drive frames.

[0007] Preferably, sliding windows are provided on both the left and right sides of the lifting frame, and are adapted to the size of the connecting plate and the driving frame.

[0008] Preferably, the top of the collection box is connected to an outer tube, and the outer side of the discharge pipe is slidably connected to the inner wall of the outer tube.

[0009] Preferably, the shaking mechanism includes a second motor, a rotating rod, and two cams. The second motor is located on the left side of the drying chamber. One end of the rotating rod is coaxially connected to the output shaft of the second motor, and the other end is rotatably connected to the right side wall of the drying chamber. The two cams are coaxially fixedly connected to the rotating rod, and their outer sides are slidably connected to the bottom end of the lifting frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The tea leaves are placed inside a placement frame, with a guide hopper connected to the bottom of the frame. A shaking mechanism causes the lifting frame to continuously shake the placement frame up and down, cleaning out the stones and impurities inside. These impurities enter the discharge pipe along the guide hopper and then into the collection box for collection. During the shaking, a leveling mechanism continuously flattens the tea leaves to prevent uneven heating of piled-up tea leaves, which would result in poor drying. Attached Figure Description

The lifting frame 2 is slidably disposed inside the drying chamber 1, located below the lifting frame 2, and driven to slide up and down continuously. It also includes multiple placement frames 4, multiple guide hoppers 5, a discharge pipe 8, and a collection box 9. The multiple placement frames 4 are spaced apart and connected between the left and right walls of the lifting frame 2. A leveling component is provided above each of the multiple placement frames 4. The multiple guide hoppers 5 are respectively connected to the bottom ends of the multiple placement frames 4 and extend to the rear side of the lifting frame 2. A lifting mechanism is provided inside the drying chamber 1 to drive the multiple sets of leveling components to rise and fall. The collection box 9 is connected to the bottom wall of the drying chamber 1. The discharge pipe 8 is connected to the rear side of the lifting frame 2 and is connected to the multiple guide hoppers 5. The bottom end of the discharge pipe 8 extends into the collection box 9.

The placement frame 4 is fixedly connected between the left and right walls of the lifting frame 2. The tea leaves in the placement frame 4 are continuously flattened using a flattening component. The tea leaves are shaken and flattened at the same time, which is equivalent to continuously turning the tea leaves over, thus speeding up the drying process. At the same time, the shaking can sieve the tea leaf fragments. The purpose of using a lifting mechanism to raise and lower the flattening component is to flatten the tea leaves according to their thickness in the placement frame 4.

[0021] In an optional embodiment, the leveling assembly includes a drive frame 61, a first motor 62, a threaded rod 63, a moving plate 64, and a plurality of pusher teeth 65.

The plurality of pusher teeth 65 are all connected to the bottom end of the moving plate 64.

[0022] It should be noted that when the tea leaves are flattened, the first motor 62 is started to drive the threaded rod 63 to rotate, which drives the moving plate 64 to move left and right, thereby moving multiple pushing teeth 65 to flatten the tea leaves. The multiple pushing teeth 65 are spaced apart, and the gaps are very small.

[0023] In an optional embodiment, the lifting mechanism includes two hydraulic cylinders 71 and two connecting plates 72.

The two cams 33 are coaxially fixedly connected to the rotating rod 32, and their outer sides are slidably connected to the bottom end of the lifting frame 2.

[0029] It should be noted that by using the second motor 31 to drive the rotating rod 32 to drive the two cams 33 to rotate, the lifting frame 2 will continuously shake up and down.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
