Description

Technical Field

[0001] This utility model relates to the field of tea cooling bed technology, specifically a multi-layer tea cooling rack. Background Technology

[0002] After tea leaves undergo high-temperature processing such as fixation, their internal chemical components are in an active state. If they proceed directly to the next process, the color of the tea leaves is prone to change. Spreading them out to cool allows the tea leaves to naturally cool at a suitable temperature, gradually stabilizing pigments such as chlorophyll and maintaining their bright green color. This prevents discoloration caused by chlorophyll destruction due to excessively high temperatures. At the same time, some chemical components inside the tea leaves, such as polyphenols and amino acids, continue to undergo slow oxidation and polymerization reactions during the cooling process. These reactions make the tea leaves taste more mellow and flavorful, and also help reduce bitterness and astringency, thus improving the quality of the tea.

[0003] Chinese utility model patent CN217523832U discloses a tea-drying bed for easy tea collection, belonging to the technical field of tea-drying beds. It includes: a bed frame with several through holes at the bottom; a support frame located at the bottom of the bed frame, with one end of the bed frame hinged to the top of the support frame; and two telescopic sections, respectively located on opposite sides of the bed frame. One end of each telescopic section is hinged to the support frame, and the other end is hinged to the bed frame. In use, tea leaves are spread flat on the bed frame, and the moisture in the tea leaves falls through the through holes. After a period of time, the tea leaves are dried, and the telescopic sections activate, raising the bed frame. Because one end of the bed frame is hinged to the support frame, the bed frame tilts, and the tea leaves slide down under gravity, falling into a pre-prepared collection basin. This utility model improves work efficiency by tilting the bed frame using the telescopic sections, thus improving work efficiency.

[0004] The existing technology described above requires manual tilting of the tea bed after the tea leaves have cooled, which is labor-intensive. Furthermore, the single-layer structure of the tea bed allows only one layer of tea leaves to be cooled, resulting in low cooling efficiency. Therefore, a multi-layer tea cooling rack is proposed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a multi-layer tea cooling rack, the purpose of which is to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-layer tea cooling rack, comprising:

[0008] The support frame contains a cooling assembly that rotates within it. The cooling assembly includes several cooling beds, which are welded and fixed together by connecting frames at the four corners. Drive components that can lift one side of the cooling assembly are installed at both ends of the support frame. A water box that can collect moisture from the tea leaves is slidably installed at the bottom of the outer end of each cooling bed.

[0009] Preferably, the bracket further includes two base plates, which are fixed together by a plurality of connecting plates. Each base plate has a first support plate fixed on one side of its upper end and a second support plate with a height lower than the first support plate fixed on the other side.

[0010] Preferably, the cooling bed further includes an outer frame located between the two first support plates. A permeable net is installed at the bottom inner end of the outer frame, and a guide plate fixed to the outer frame is provided at the opening of the outer frame. When the cooling assembly is in an inclined state, the tea leaves in the cooling bed are discharged through the guide plate.

[0011] Preferably, the outer frame at the top of the cooling assembly is rotatably connected to the first support plate at the corresponding location via a support shaft. Support columns are fixed on both sides of the outer end of the uppermost outer frame away from the support shaft. A support column connected to the drive assembly is rotatably provided on the side of the support column away from the outer frame. The support column can be pushed and lifted by the drive assembly.

[0012] Preferably, the drive assembly further includes a cylinder located on the side of the second support plate away from the cooling bed and mounted on the upper part of the base plate. The output end of the cylinder is fixed with a drive rod, and the upper end of the drive rod is fixed with a lifting frame. The lifting frame is sleeved on the outside of the support column and has a limiting groove inside for the movement of the support column.

[0013] Preferably, the water box is provided with limiting strips on both sides of its outer end, and the bottom sides of the outer frame are provided with support frames corresponding to the limiting strips. A sliding groove is provided on the side of the support frame near the water box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model provides a multi-layer tea cooling rack, which is equipped with a drive component to lift one side of the cooling component. After the cylinder is activated, the lifting frame is driven to rise and fall through the drive rod. During the lifting process, one side of the cooling bed at the highest point of the cooling component can be lifted. At this time, the first support plate rotates through the connection with the outer frame as the axis, so that the entire cooling component is tilted. The tea leaves are discharged from the cooling bed through the guide plate, thus eliminating the need for manual tilting of the cooling component, reducing labor costs and making it more convenient to use.

[0016] By installing a water box at the bottom of the outer end of each cooling bed, the water flowing out of the cooling bed can be collected, preventing water from the upper cooling bed from flowing into the lower cooling bed due to the multi-layer design. The water box can be easily removed and the water poured out by sliding at the bottom of the outer end of the cooling bed, making the operation simple. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 and Figure 3 The embodiments proposed in this application are as follows: a multi-layer tea cooling rack, including a support 10, a cooling component rotatably disposed inside the support 10, the cooling component including a plurality of cooling beds 20, the plurality of cooling beds 20 being welded and fixed by connecting frames 30 at the four corners to form an integrated structure, when the cooling bed 20 is in a flat state, the tea to be cooled is laid in the cooling bed 20, and a drive component 50 is installed at both ends of the support 10, which can lift one side of the cooling component, so that the cooling component is tilted, so that the cooled tea can be poured out and collected;

[0025] For details, see Figure 1 and Figure 3 The support frame 10 includes two base plates 11, which are fixed together by several connecting plates. Each base plate 11 has a first support plate 12 fixed on one side of its upper end and a second support plate 13 with a lower height than the first support plate 12 fixed on the other side. The two first support plates 12 support one side of the cooling component, and the two second support plates 13 support the other side of the cooling component. The cooling bed 20 includes an outer frame 21 located between the two first support plates 12. A permeable net 22 is installed at the bottom of the inner end of the outer frame 21 to facilitate the drainage of water from the tea leaves. A guide plate 23 is provided at the opening of the outer frame 21 and is fixed to the outer frame 21. This allows the tea leaves located in different cooling beds 20 to be discharged uniformly through the corresponding guide plate 23 after the cooling component is tilted, so that the staff can collect the tea leaves. The distance between adjacent cooling beds 20 is not less than 30cm to facilitate the staff to lay the tea leaves in the cooling bed 20.

[0026] See Figure 1 and Figure 4 In the cooling assembly, the outer frame 21 at the top is rotatably connected to the first support plate 12 at the corresponding position via a support shaft 211. The first support plate 12 can be used as a rotatable support axis through the connection between the support shaft 211 and the outer frame 21. Support columns 212 are fixed on both sides of the outer end of the outer frame 21 at the top of the cooling assembly away from the support shaft 211. A support column 213 connected to the drive assembly 50 is rotatably provided on the side of the support column 212 away from the outer frame 21. During the process of the support column 213 being pushed and lifted by the drive assembly 50, the first support plate 12 rotates through the connection between the support shaft 211 and the outer frame 21 as the support axis, so that the cooling assembly can be tilted. At the same time, when the cooling assembly is in a flat position, the second support plate 13 is located directly below the support column 212. Thus, when the cooling assembly is in a flat position, the second support plate 13 can contact the corresponding support column 212, thereby supporting the other side of the outer frame 21 at the top of the cooling assembly and keeping the cooling assembly in a flat position.

[0027] See Figure 1 , Figure 2 and Figure 4The drive assembly 50 includes a cylinder 51 located on the side of the second support plate 13 away from the cooling bed 20 and mounted on the upper end of the base plate 11. A drive rod 52 is fixed to the output end of the cylinder 51, and a lifting frame 53 is fixed to the upper end of the drive rod 52. The lifting frame 53 is sleeved on the outside of the support column 213 and has a limiting groove for the movement of the support column 213. After the cylinder 51 is started, it can drive the lifting frame 53 to rise and fall through the drive rod 52. During the rising and falling of the lifting frame 53, one side of the cooling bed 20 at the highest point of the cooling assembly can be lifted, so that the entire cooling assembly becomes tilted. At this time, the first support plate 12 rotates through the connection with the outer frame 21 as the axis, and the support column 213 slides in the limiting groove of the lifting frame 53 and rotates. Through the rotation of the support column 213, the friction force on the support column 213 in the limiting groove of the lifting frame 53 is reduced, and the service life of the parts is improved.

[0028] When the cooling assembly is in a flat position, the tea leaves to be cooled are laid on the cooling bed 20. After the tea leaves are laid, the drive component 50 lifts one side of the cooling assembly, causing the entire cooling assembly to tilt. The tea leaves are then discharged from the cooling bed 20 through the guide plate 23. During this process, the staff can pre-position a collection box or collection bin on the outside of the tea cooling rack corresponding to the guide plate 23 to collect the tea leaves discharged from the guide plate 23. After collection, the drive component 50 resets, and the cooling assembly returns to a flat position. The drive component 50 then drives the cooling assembly to tilt, eliminating the need for manual tilting, reducing labor costs, and making it more convenient to use. Furthermore, the cooling assembly consists of several cooling beds 20 in a multi-layer configuration, allowing for simultaneous batch cooling of tea leaves and improving cooling efficiency.

[0029] A vibration motor can be added to the outer frame 21 as needed. The vibration motor drives the entire cooling bed 20 to vibrate. When the cooling bed 20 is tilted, it helps the tea leaves to be discharged from the cooling bed 20 more quickly. At the same time, the vibration motor needs to be waterproofed to prevent it from getting damp.

[0030] In a further embodiment, see Figure 1-5Each cooling bed 20 has a water box 40 slidably installed at the bottom of its outer end. When the water box 40 is connected to the cooling bed 20, it can collect the water flowing out of the tea leaves from the cooling bed 20. Limiting strips 41 are provided on both sides of the outer end of the water box 40. Support frames 214 corresponding to the limiting strips 41 are provided on both sides of the bottom of the outer end of the outer frame 21. A sliding groove is opened on the side of the support frame 214 near the water box 40, so that when the water box 40 is connected to the cooling bed 20, the support frame 214 can lift the corresponding limiting strips 41, thereby supporting the water box 40 as a whole. When it is necessary to slide the water box 40 out from the bottom of the cooling bed 20, the limiting strips 41 can slide in the sliding groove of the corresponding support frame 214.

[0031] By providing a water box 40 at the bottom outer end of each cooling bed 20, the water box 40 collects water flowing out of the cooling bed 20, preventing water from the upper cooling bed 20 from flowing into the lower cooling bed 20 due to the multi-layer design. The sliding arrangement of the water box 40 at the bottom outer end of the cooling bed 20 facilitates easy removal and emptying of the water, simplifying operation.
