Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to an auxiliary structure of a tea drying rack. Background Art

[0002] Tea is a common beverage ingredient, usually made from the tender leaves of tea trees that are picked and processed. Drying tea leaves is an important part of tea processing, which helps the drying and oxidation process of tea leaves. The tea drying process is usually carried out in the sun or in a well-ventilated place, so that air and sunlight can fully contact the surface of the tea leaves, helping the tea leaves to dry and oxidize quickly.

[0003] The current method of drying tea is to spread it on the ground to dry, or use a large winnowing basket for drying. The drying process is rather arduous, consumes a lot of labor, requires a large area, takes a long time to dry, has relatively low drying efficiency, and is greatly restricted by weather factors, and cannot meet the needs of large-scale rapid drying.

[0004] A Chinese patent for a new type of tea drying rack (publication number CN209893856U) is proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: "It includes a drying rack body and a plurality of drying trays arranged on the drying rack body. The drying rack body includes a first frame and a second frame hinged to the first frame. The first frame has a first frame, which is in the shape of a Chinese character "U", and universal wheels are respectively arranged on both sides of the bottom. There are a plurality of first cross braces arranged at a certain height inside. The first cross brace is provided with a notch near the middle position. The length of the notch is greater than the cross-sectional length of the first cross brace. When the notch is set, the upper surface of the first cross brace is retained; the second frame has a second frame, which is in the shape of a Chinese character "U", and there are a plurality of second cross braces arranged at a certain height inside. The cross-sectional dimensions of the second cross brace and the first cross brace are the same. Compared with the prior art, the utility model is convenient for drying, can effectively reduce the demand for space, reduce the labor intensity of workers, and improve the drying efficiency of tea leaves."

[0005] However, this technical solution may cause great operational inconvenience due to the height of the operator. In order to meet the demand for more drying in a limited drying area, the first frame usually has a certain height in the vertical direction, which makes it inconvenient to place or take the drying tray. In addition, since the drying rack itself has a high center of gravity, there will be certain safety hazards if objects are used as footrests. Therefore, it is convenient to propose an auxiliary structure of a tea drying rack that can be raised and lowered. Summary of the invention

[0006] The purpose of the utility model is to provide an auxiliary structure of a tea drying rack to solve the problems raised in the above background technology.

In the drying state, the active lifting frame can be located at the highest position so that each driven lifting frame can be located at a position corresponding to the length of the linkage slide bar. When loading or unloading is required, the active lifting frame can be lowered so that the support plate loses support, and the driven lifting frame will be lowered to different degrees to facilitate the removal of the bamboo sieve, thereby greatly facilitating the operation of drying tea leaves.

[0010] A further improvement of the technical solution of the utility model is that the lifting component includes a screw rod and a fixed plate, the fixed plate is fixedly connected between the inner walls of the lifting adjustment groove, the screw rod is rotatably connected between the top of the inner wall of the lifting adjustment groove and the top of the fixed plate, the outer side of the screw rod is threadedly connected with a slider, the outer side of the slider is slidingly connected to the inner wall of the lifting adjustment groove, the two ends of the active lifting frame are respectively fixedly connected to the two sliders, and a linkage component for realizing power transmission for the two screw rods is arranged between the two main columns.

[0014] A further improvement of the technical solution of the utility model is that the tops of the active lifting frame and the driven lifting frame are both symmetrically fixedly connected with separation blocks.

[0015] By adopting the above technical solution, when each active lifting frame descends to a certain position, each driven lifting frame is separated and supported by the partition block, so that there is a gap between them, which is convenient for placing the bamboo screen.

[0016] A further improvement of the technical solution of the utility model is that an auxiliary slide groove is opened on the side of the auxiliary column close to the connecting frame, a support plate is slidably connected between the inner walls of the auxiliary slide groove, a bolt is threadedly connected to one side of the auxiliary column, one end of the bolt extends to the inside of the auxiliary slide groove and is rotatably connected to the support plate, and a support block is fixedly connected to the side of the support plate away from the bolt.

[0017] By adopting the above technical solution, the support plate is made to contact the driven lifting frame and the active lifting frame by rotating the bolt, and the support block provides auxiliary support for one end of the driven lifting frame and the active lifting frame, making the support more stable.

[0018] A further improvement of the technical solution of the utility model is that the lengths of the linkage slide bars located at different driven lifting frames are different.

[0019] By adopting the above technical solution, when the active lifting frame is at the highest position, each driven lifting frame can be lifted to different height positions through linkage slide bars of different lengths.

[0020] A further improvement of the technical solution of the utility model is that the bottoms of the main column and the auxiliary column are fixedly connected with a base.

After placement, the handle 19 is turned in the opposite direction to rotate the rotating rod 16, and the first bevel gear 17 is engaged with the second bevel gear 18 to drive the screw rod 5 to rotate, so that the slider 6 rises until the active lifting frame 7 completely lifts the support plate 10. At this time, the driven lifting frames 9 are all at the maximum distance. At this time, the bolt 13 can be turned to make the support plate 14 contact the driven lifting frame 9 (and the active lifting frame 7). At the same time, the support block 15 provides auxiliary support for one end of the driven lifting frame 9 to make the support more stable, and then it can be dried. After drying, each lifting frame can be lowered through the operation before drying to facilitate the removal of tea leaves.
