Description

Technical Field

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

[0002] Tea refers to the tender leaves, buds, and stems picked from the tea plant, which are processed into a beverage raw material for human consumption. During the tea processing, a withering process is required. Withering is a key step in the initial processing of tea. It involves spreading the freshly picked leaves to a certain thickness, allowing them to lose some moisture under suitable environmental conditions, and causing a series of physical and chemical changes in the fresh leaves. Nowadays, withering devices are often used to complete the withering process of tea. In practice, they have the advantages of simple operation, stable structure, and good performance.

[0003] The existing withering device requires a shielding structure to prevent the tea leaves from being directly blown by the side wind. When the two shielding structures are connected to the withering box body, there is no alignment structure, making it difficult to easily align the two shielding structures with the withering box body, which brings inconvenience to the installation of the existing withering device. At the same time, the spreading structure inside the withering box body is fixedly installed, making it difficult for operators to unload the tea leaves piled up on the top of the spreading structure.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a tea withering device, which has the following beneficial effects:

[0016] (1) This utility model is equipped with a concave seat. When the tea withering device is actually used, the four sets of universal wheels on the same side can move the concave baffle on the same side. When the two sets of abutting rollers on the same side are inside the concave baffle on the same side, the operator can rotate the handwheel on the same side by hand. This handwheel can drive the double-acting lever on the same side to rotate. Since the double-acting lever on the same side and the two sets of screw sleeves on the same side are threaded together, the rotating double-acting lever on the same side can push the two sets of screw sleeves on the same side closer or further apart. When the two sets of screw sleeves on the same side pass through the two sets of sleeve plates and the two sets of concave plates on the same side, the two sets of abutting rollers on the same side move towards each other. When moving away, push one set of concave baffles on the same side to align them with the frame. Then move the other set of concave baffles towards the frame. The other set of concave baffles can be used in the same way. Then, the two sets of mounting screws can be passed through the four sets of mounting holes. Then, use the mounting screws on the same side and the two sets of mounting nuts on the same side to engage with each other. The operator can manually rotate the four sets of mounting nuts clockwise and counterclockwise onto the side walls of the two sets of mounting screws to complete the connection and installation of the two sets of concave baffles with the frame. The concave seats have an alignment structure, which can facilitate the alignment and connection of the shielding structure, bringing convenience to the installation of the tea withering device.

[0017] (2) This utility model is equipped with a frame plate and a hollowed-out drying plate. According to the above operation, after the two sets of concave baffles are connected to the frame, the tea can be spread flat on the hollowed-out drying plate. When the side wind enters a set of airflow channels, the same set of rotating shafts and the same set of four guide plates on the same side can be rotated to disperse and guide the side wind blowing directly on the frame. When it is necessary to unload the withered tea, the four sets of connecting screws and eight sets of connecting nuts are used to cooperate with each other. The operator rotates the eight sets of connecting nuts clockwise and counterclockwise by hand. When the eight sets of connecting nuts are separated from the frame plate, the four sets of brake plates can be moved. When the four sets of brake plates are separated from the front and rear end faces inside the frame, the frame plate can be rotated with the two sets of mounting shafts as the central axis. At this time, under the action of gravity, the tea on the hollowed-out drying plate can be poured out. Through the frame plate and the hollowed-out drying plate, it is easy to realize the unloading operation of the tea piled on the top of the drying structure, which improves the practicality of the tea withering device.

[0035] In one embodiment, four sets of casters are installed at the bottom of each of the two sets of concave baffles 2.

[0036] Working principle:

[0037] In actual use of the tea withering device, four sets of universal wheels on the same side can move one set of concave baffles 2 on the same side. When two sets of contact rollers 16 on the same side are located inside the concave baffles 2 on the same side, the operator can rotate one set of handwheels 18 on the same side. This set of handwheels 18 can drive one set of bidirectional lead levers 12 on the same side to rotate. Since the one set of bidirectional lead levers 12 and the two sets of lead screw sleeves 13 on the same side are threadedly engaged, the rotating one set of bidirectional lead levers 12 on the same side can push the two sets of lead screw sleeves 13 on the same side closer or further apart. When the two sets of lead screw sleeves 13 on the same side pass through the two sets of sleeves on the same side... When the connecting plate 14 and the two sets of concave plates 15 on the same side move the two sets of abutting rollers 16 away from each other, the set of concave baffles 2 on the same side can be pushed to align with the frame 1. Then, the set of concave baffles 2 on the same side can be moved toward the frame 1. The use of the other set of concave baffles 2 is the same as the operation. Then, the two sets of mounting screws 10 can be passed through the four sets of mounting hole plates 9. Then, the set of mounting screws 10 on the same side and the two sets of mounting nuts 11 on the same side are threaded together. The operator can use his hand to put the four sets of mounting nuts 11 clockwise and counterclockwise onto the side walls of the two sets of mounting screws 10 to complete the two sets of concave plates 16. The connection and installation of the baffle 2 and the frame 1 are facilitated by the concave seat 3, which provides an alignment structure. This makes it easy to align the baffle structure and facilitates the installation of the tea withering device. Furthermore, as described above, after the two sets of concave baffles 2 are connected to the frame 1, the tea can be spread flat on the perforated drying plate 5. When a side wind enters a set of airflow channels 6, a set of rotating shafts 7 and four sets of guide plates 8 on the same side can rotate, dispersing and guiding the side wind blowing directly onto the frame 1. When it is necessary to unload the withered tea, the four sets of connecting screws 20 are used... The eight sets of connecting nuts 21 are threaded together. The operator can rotate the eight sets of connecting nuts 21 clockwise and counterclockwise by hand. When the eight sets of connecting nuts 21 are separated from the frame plate 4, the four sets of brake plates 22 can be moved. When the four sets of brake plates 22 are separated from the front and rear end faces inside the frame 1, the frame plate 4 can be rotated with the two sets of mounting shafts 19 as the central axis. At this time, under the action of gravity, the tea leaves on the hollow drying plate 5 can be poured out. Through the frame plate 4 and the hollow drying plate 5, the unloading operation of the tea leaves piled on the upper part of the drying structure can be easily realized, which improves the practicality of the tea withering device.
