Description

Technical Field

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

[0002] Freshly picked leaves retain their vibrant physiological state, continuously releasing heat through internal respiration and possessing a high moisture content. If directly piled up, this heat cannot dissipate, easily leading to localized overheating. This can not only cause mold but also damage the original flavor compounds due to excessive enzyme activity, resulting in a musty or astringent taste, affecting the quality of subsequent processing. Spreading out the leaves to air dry allows them to soften and become more resilient through natural moisture loss, facilitating subsequent shaping. It also allows for the initial transformation of flavor compounds through gentle contact with the environment, laying the foundation for the final aroma and taste.

[0003] According to the authorization announcement number (CN211268447U), a multi-layer tea tray spreading rack structure that allows for real-time flipping and shaking at the workstation includes a main frame with several layers of vibrating racks arranged from top to bottom within the frame. Each layer of vibrating racks is equipped with movable tea trays. In actual operation, tea leaves are first evenly spread on each layer of tea trays for spreading and drying. Then, the vibrating racks drive the tea trays to vibrate, causing the tea leaves to flip and shake within the trays, thus improving the spreading and drying effect.

[0004] The structure disclosed in this patent has defects in practical applications, specifically as follows: multiple tea trays are arranged from top to bottom within the frame to achieve the spreading operation. Although this can increase the processing capacity per batch, the multi-layered structure makes the overall size of the equipment huge, significantly increasing the space requirements of the work site. At the same time, it requires a lot of storage space when idle, making it difficult to store efficiently. Furthermore, it cannot be compressed during transportation, which significantly restricts the equipment during transportation. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0032] Example

[0033] Please refer to Figures 1 to 7 This utility model provides a tea-drying device. It includes a base 1, two uprights 4, multiple support beams 6, a top frame 8, multiple tea-drying trays 7, and a storage box 2. The two uprights 4 are detachably assembled on both sides of the base 1, forming an installation area for mounting the tea-drying trays 7. The multiple support beams 6 are fixed vertically from top to bottom to the inner wall of the uprights 4. The top frame 8 is detachably connected to the top of the two uprights 4, providing axial restraint to ensure overall structural stability. The multiple tea-drying trays 7 are correspondingly installed within the installation area, with each side of the tray 7 detachably connected to a corresponding support beam 6 for supporting tea leaves and allowing for drying. The storage box 2 is located on the base 1 and has an open storage channel 3 vertically from top to bottom for centralized storage of the components after disassembly.

[0034] During the disassembly process, firstly, disconnect the top frame 8 from the uprights 4 and remove the top frame 8 from the top of the uprights 4; secondly, separate the uprights 4 from the base 1 and remove the two uprights 4 from both sides of the base 1; finally, place the multiple drying trays 7, the two uprights 4, and the top frame 8 into the storage channel 3 of the storage box 2 (elastic plugs can seal the ports of the storage channel 3). By integrating components for storage, the overall space occupied is reduced, meeting the needs of convenient storage and transportation.

[0035] During the installation process, the device containing all components is first transported to the designated tea-drying location. Multiple drying trays 7, two uprights 4, and a top frame 8 are then removed from the storage channel 3. The two uprights 4 are then assembled on both sides of the base 1. After the installation of the uprights 4 and the base 1 is completed, the top frame 8 is installed on the top of the uprights 4 to limit their position. Finally, the multiple drying trays 7 are assembled vertically from top to bottom onto the corresponding support beams 6. After installation, the tea leaves are spread on each drying tray 7 for drying.

[0036] Please refer to Figure 3In some embodiments of this application, the base 1 has a first mounting groove 18 on each side, and a first receiving groove 19 is formed through the side wall of the first mounting groove 18. A first positioning component 10 is assembled inside the first receiving groove 19. Correspondingly, a first mounting body 12 is fixedly provided at the bottom end of the stand 4. The outer dimensions of the first mounting body 12 are adapted to the first mounting groove 18. At the same time, a first positioning hole 13 is provided on the first mounting body 12. The position of the first positioning hole 13 corresponds to the position of the first positioning component 10 in the first receiving groove 19, so as to form a positioning fit to realize the connection and fixation between the stand 4 and the base 1.

[0037] When installing the upright 4 and the base 1, the first insert 12 at the bottom of the upright 4 is first inserted into the first insert groove 18 on the side of the base 1 along a preset direction. The initial positioning of the upright 4 relative to the base 1 is completed by the insert structure, which restricts the horizontal displacement of the upright 4. After the initial positioning is in place, the first positioning component 10 in the first receiving groove 19 is driven so that the first positioning component 10 and the first positioning hole 13 form a positioning fit, thereby realizing the secondary positioning and rigid fixation of the upright 4 and the base 1.

[0038] Please refer to Figure 3 Specifically, the first positioning component 10 consists of a first pin 21 and a first spring 20. The first pin 21 is movably inserted along the axial direction of the first receiving groove 19 and can move back and forth along the extension direction of the first receiving groove 19 to provide a basis for inserting into or disengaging from the first positioning hole 13. The first spring 20 is coaxially fitted on the outside of the first pin 21. One end of the first spring 20 is fixedly connected to the outer peripheral wall of the first pin 21, and the other end is fixedly connected to the inner wall of the first receiving groove 19. When the first spring 20 is in a naturally extended state, it can drive the first pin 21 to move towards the first insert groove 18 until the end of the first pin 21 is embedded in the first positioning hole 13, forming a positioning constraint between the stand 4 and the base 1.

[0039] It should be noted that a number of first receiving slots 19 are opened at intervals on the first mounting slot 18, and a complete set of first positioning components 10 is assembled inside each first receiving slot 19; accordingly, a number of first positioning holes 13 are opened synchronously along the length direction on the first mounting body 12 at the bottom of the stand 4.

[0040] Please refer to Figure 4In some embodiments of this application, the top frame 8 is provided with second mounting grooves 22 on both sides, and the groove wall of the second mounting groove 22 is provided with a second receiving groove 23. The second receiving groove 23 is fixedly installed with a second positioning component 11. Correspondingly, the top of the stand 4 is fixedly provided with a second mounting body 14. The structural dimensions of the second mounting body 14 are adapted to the second mounting groove 22, and it can be embedded into the second mounting groove 22 to form a preliminary fit. The second mounting body 14 is provided with a second positioning hole 15. The position of the second positioning hole 15 corresponds to the second positioning component 11 in the second receiving groove 23, and the rigid connection between the top frame 8 and the stand 4 can be achieved through positioning fit.

[0041] Specifically, the second positioning component 11 is composed of a second pin 25 and a second spring 24. The second pin 25 is movably inserted along the axial direction of the second receiving groove 23 and has the action conditions to engage or disengage with the second positioning hole 15. The second spring 24 is coaxially fitted on the outside of the second pin 25. One end of the second spring 24 is fixedly connected to the outer peripheral wall of the second pin 25, and the other end is fixedly connected to the inner wall of the second receiving groove 23. When the second spring 24 is in a naturally extended state, it can push the second pin 25 to move towards the second mounting groove 22 until the end of the second pin 25 is embedded in the second positioning hole 15, forming a positioning lock between the top frame 8 and the upright 4.

[0042] The working principle of the second positioning component 11 and the installation process of the top frame 8 and the upright 4 are completely consistent with the positioning principle and installation logic of the upright 4 and the base 1 mentioned above, and will not be elaborated here.

[0043] In some embodiments of this application, the support frame 4 is composed of two opposing pillars 5; each pillar 5 includes a plurality of telescopic sleeves 30 connected in sequence, and two adjacent telescopic sleeves 30 can be fixed to a preset telescopic position by a limiting structure; the plurality of telescopic sleeves 30 of the two pillars 5 are distributed in a one-to-one correspondence, and a support beam 6 is fixedly connected between two corresponding telescopic sleeves 30 in the two pillars 5.

[0044] The support beam 6, acting as a linkage component corresponding to the two telescopic sleeves 30, ensures that the two pillars 5 maintain synchronous extension and contraction during adjustment, thereby guaranteeing the symmetry and stability of the overall structure. During the storage and transportation phase, the telescopic sleeves 30 of the upright frame 4 can be retracted to their shortest state, minimizing the overall volume of the upright frame 4 to fit the size of the storage channel 3 of the storage box 2. Because the spreading operation requires more spreading trays 7 to increase the tea spreading capacity, the upright frame 4 was initially designed to be quite tall, and its volume in the unfolded state is greater than the volume of the storage channel 3. The storage requirements can be met by retracting and adjusting.

[0045] On the other hand, when carrying out the drying operation indoors or outdoors, there may be various obstructions, such as ceilings, beams, and hanging lights in the indoor environment, or tree branches, eaves, and overhead cables in the outdoor environment. At this time, the overall height can be changed by adjusting the extension length of the stand 4, thereby avoiding obstructions, ensuring that the drying space is not interfered with, and ensuring ventilation and lighting conditions during the tea drying process.

[0046] Please refer to Figure 7 Specifically, within the same support column 5, two adjacent telescopic sleeves 30 are connected by a connecting sleeve 31; both ends of the connecting sleeve 31 are fitted onto the outer periphery of the adjacent telescopic sleeves 30 in a movable manner, and both outer walls of the connecting sleeve 31 are equipped with limiting components; the telescopic sleeves 30 are provided with multiple limiting through holes 35 spaced apart along the axial direction, and when the telescopic sleeves 30 are adjusted to a preset telescopic position relative to the connecting sleeves 31, the limiting through holes 35 at the corresponding positions can form a limiting engagement with the limiting components.

[0047] The limiting component specifically consists of a limiting seat 32, a limiting pin 36, and a third spring 34. The limiting seat 32 has a through-type assembly channel 33 and is fixedly installed on the outer wall of the connecting sleeve 31. The limiting pin 36 is movably inserted along the axial direction of the assembly channel 33 and penetrates the wall of the connecting sleeve 31. The third spring 34 is coaxially sleeved on the outside of the limiting pin 36. One end of the third spring 34 is connected to the outer peripheral wall of the limiting pin 36, and the other end is connected to the inner side wall of the assembly channel 33. When the third spring 34 is in a naturally extended state, it can drive the limiting pin 36 to move towards the telescopic sleeve 30 until it is embedded in the preset limiting through hole 35 to form a rigid limit.

[0048] One end of the limiting pin 36 extends to the outside of the assembly channel 33, forming an operating end for the operator to apply force; the other end penetrates the wall of the connecting sleeve 31 and can extend towards the limiting through hole 35 of the telescopic sleeve 30. Under the action of the third spring 34, after the limiting pin 36 is embedded in the corresponding limiting through hole 35, it can continue to extend to the other side of the telescopic sleeve 30, successively penetrating the other side wall of the telescopic sleeve 30 and the corresponding side wall of the connecting sleeve 31. Through the multi-dimensional penetration structure, a composite constraint is formed, which significantly improves the structural stability of the telescopic sleeve 30 in the limiting position.

[0049] In some embodiments of this application, the support beam 6 has a groove 9 axially formed on the side facing the installation area. One end of the groove 9 is an open structure 16 and the other end is a closed structure 17. The two sides of the drying tray 7 are respectively structurally adapted to the groove 9 of the corresponding support beam 6 and can be embedded in the groove along the extension direction of the groove 9.

[0050] When installing the drying tray 7, align the two side edges of the drying tray 7 with the opening structures 16 of the two opposing support beams 6 until the end of the drying tray 7 abuts against the closed structure 17 of the slide 9, thereby achieving the positioning and stable assembly of the drying tray 7 on the support beams 6.

[0051] It should be noted that the spreading tray 7 adopts a combined structure of frame and support net. The support net is embedded and fixed in the inner cavity of the frame to form a tea-bearing surface with air-permeable function. The two ends of the spreading tray 7 are integrally formed with sliding bodies, which slide in the groove 9 during assembly.

[0052] Please refer to Figure 5 and Figure 6 In some embodiments of this application, the slide groove 9 has an opening structure 16 with an installation channel 26; an elastic element 27 (spring) is installed in the installation channel 26, one end of the elastic element 27 is rigidly connected to the inner wall of the installation channel 26, and the other end is fixedly connected to the locking block 28; the locking block 28 is movably embedded in the installation channel 26, and the locking block 28 is provided with a guide slope 29.

[0053] In the first state, when the drying tray 7 is embedded in the opening structure 16 of the slide groove 9, the edge of the drying tray 7 contacts the guide slope 29 of the locking block 28 and forms a wedge fit. The force transmission of the guide slope 29 pushes the locking block 28 to move into the installation channel 26, and simultaneously compresses the elastic element 27 until the locking block 28 is completely retracted into the installation channel 26, releasing the obstruction of the slide groove 9 channel, allowing the drying tray 7 to continue to advance along the channel;

[0054] In the second state, when the drying tray 7 is fully inserted into the slide groove 9 and comes into contact with the closed structure 17, the edge of the drying tray 7 disengages from the locking block 28. Under the reset force of the elastic element 27, the locking block 28 partially extends out of the mounting groove 26 and into the slide groove 9. At this time, the straight end face of the locking block 28 away from the guide slope 29 forms a rigid limit with the side edge of the drying tray 7, preventing the drying tray 7 from accidentally slipping out of the slide groove 9.

[0055] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
