Description

Technical Field

[0001] This utility model belongs to the technical field of agricultural product processing, specifically relating to a device for evenly drying tea leaves. Background Technology

[0002] Evenly dried tea leaf sun-drying equipment is a key piece of equipment in the initial processing of tea. It is mainly used to remove excess moisture from fresh tea leaves through natural sun drying, while simultaneously promoting the transformation of internal substances in the tea leaves, laying a quality foundation for subsequent processes such as fixation and rolling. These devices typically employ a layered frame design, allowing multiple batches of tea leaves to be dried simultaneously within a limited space. Furthermore, by adjusting the drying position to match the angle of sunlight, they ensure even heating of the tea leaves, preventing localized over-drying or under-drying that could affect quality. They are widely used in large-scale sun-drying operations in tea plantations and tea companies.

[0003] However, existing tea sun-drying equipment mostly relies on manual monitoring of weather changes to cope with rain and fog. Since tea sun-drying is mostly done outdoors, it is often difficult to accurately predict sudden thunderstorms and severe convective weather in advance. When it rains, if the equipment does not have a quick protective structure, the tea leaves need to be carried manually to a rain shelter one by one. This is not only time-consuming and laborious, but also prone to problems such as the tea leaves being soaked by rainwater due to inadequate protection, resulting in mold and blackening of the leaves, which directly affects the quality of the tea. Utility Model Content

[0004] The purpose of this invention is to provide a tea drying device that can evenly dry tea leaves, in order to solve the problems mentioned in the background art. Existing tea drying devices rely on manual weather monitoring to deal with rain and fog. Outdoor thunderstorms are difficult to predict, and when there is no quick protective structure, the tea leaves need to be manually moved to a rain shelter, which is time-consuming, laborious, and prone to untimely protection, resulting in the tea leaves getting wet, moldy, and turning black, thus affecting the quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tea drying device for uniform drying, comprising four vertical supports and a drying tray placement frame A fixedly connected between the lower sides of the centers of the four vertical supports, a drying tray placement frame B fixedly connected between the upper sides of the centers of the four vertical supports, and both the drying tray placement frame A and the drying tray placement frame B are fixed in a horizontal state. Multiple tea drying trays are placed on both the drying tray placement frame A and the drying tray placement frame B. A rain and fog protection device is connected between the two vertical supports connected to the left end and the two vertical supports connected to the right end of the drying tray placement frame A.

[0006] Preferably, the rain and fog protection device includes a longitudinal track frame A and a longitudinal track frame B. The longitudinal track frame A is arranged in a front-to-back longitudinal position on the right side of the two vertical supports located at the right end of the drying tray placement frame A, and the longitudinal track frame B is arranged in a front-to-back longitudinal position on the left side of the two vertical supports located at the left end of the drying tray placement frame A.

[0007] Preferably, the rain and fog timely protection device further includes U-shaped fixing sleeves. U-shaped fixing sleeves are welded to the outer walls of the front and rear sides at the center of the left end of the longitudinal track frame A and the outer walls of the front and rear sides at the center of the right end of the longitudinal track frame B. Multiple U-shaped fixing sleeves are respectively fitted onto the outside of the vertical brackets corresponding to their positions, and the U-shaped fixing sleeves are fixedly connected to the vertical brackets by multiple screws.

[0008] Preferably, the rain and fog timely protection device further includes a sealing block, a T-shaped anti-detachment groove, and a T-shaped anti-detachment slider. Both longitudinal track frame A and longitudinal track frame B are provided with T-shaped anti-detachment grooves. A sealing block is inserted into the front opening of each of the two T-shaped anti-detachment grooves, and the sealing block is fixedly connected to longitudinal track frame A and longitudinal track frame B by screws. A T-shaped anti-detachment slider is provided in each of the two T-shaped anti-detachment grooves. The sealing block can prevent the T-shaped anti-detachment slider from sliding out of the front opening of the T-shaped anti-detachment groove.

[0009] Preferably, the rain and fog protection device further includes a U-shaped metal slide, a rainproof tarpaulin, and a U-shaped metal fixing frame. The U-shaped metal slide is arranged with its U-shaped opening facing downwards, and both ends of the opening of the U-shaped metal slide are respectively fixedly connected to the tops of two T-shaped anti-detachment sliders by welding. At the same time, the U-shaped metal slide is respectively fitted onto the left and right sides and the upper exterior of the tea drying device. The rear ends of the longitudinal track frame A and the longitudinal track frame B are fixedly connected to the U-shaped metal fixing frame. The U-shaped metal fixing frame is located parallel to the rear side of the U-shaped metal slide, and a rainproof tarpaulin is fixedly connected between the U-shaped metal fixing frame and the U-shaped metal slide.

[0010] Preferably, during the back-and-forth movement of the two T-shaped anti-detachment sliders in the two T-shaped anti-detachment grooves, the U-shaped metal slide will synchronously drive the U-shaped metal slide to move back and forth. When the T-shaped anti-detachment sliders drive the U-shaped metal slide to slide forward until it is blocked by the sealing block, the rainproof tarpaulin is pulled forward by the U-shaped metal slide and is in a fully unfolded state. The U-shaped metal slide can retract the unfolded rainproof tarpaulin by moving backward. After the rainproof tarpaulin is fully retracted, the U-shaped metal slide, the rainproof tarpaulin, and the U-shaped metal fixing frame are all located behind the tea drying device.

[0011] Preferably, both the drying tray placement frame A and the drying tray placement frame B have multiple placement stops equidistantly arranged from left to right inside their frames, and the top outer walls of the multiple placement stops inside the frames are flush with each other.

[0012] Preferably, each of the four vertical supports is fixedly connected to a top reinforcing link near its top, and the top reinforcing link is located above the perimeter of the drying tray mounting frame B. Each of the four vertical supports is fixedly connected to a bottom reinforcing link near its bottom, and the bottom reinforcing link is located below the perimeter of the drying tray mounting frame A.

[0013] Preferably, each of the four vertical supports is welded with a wheel at its bottom, and each of the four wheel bases is fixed with a movable wheel by screws. All four movable wheels are omnidirectional wheels with built-in braking function.

[0014] Compared with the prior art, this utility model provides a tea drying device for uniform drying, which has the following beneficial effects:

[0015] This invention adds a novel rain and fog protection device to the tea drying device. This device can quickly respond to unpredictable rain and fog weather such as sudden thunderstorms and strong convection, and can achieve rain protection without moving the tea drying device. It effectively solves the problem of untimely manual protection when using large-scale tea drying devices, ensuring the quality of dried tea. It also has the advantages of convenient operation and stable structure. When using tea drying devices in large-scale tea drying, if unpredictable thunderstorms or strong convection weather are encountered, the traditional method requires manual movement of multiple devices to a rain shelter, which is not only time-consuming and labor-intensive, but also prone to tea being soaked by rainwater due to untimely protection. The rain and fog protection device has a sliding and unfolding design. Simply push the U-shaped metal slide to make it move the T-shaped anti-detachment slider forward in the T-shaped anti-detachment sliding groove of the longitudinal track frame A and longitudinal track frame B until it is blocked by the sealing block. The rainproof tarpaulin can be quickly and completely unfolded to cover the left and right sides and the top of the tea drying device, which greatly shortens the protection response time. Even large-scale devices can be protected efficiently, avoiding problems such as mold and quality decline of tea due to rain.

[0016] Furthermore, even if the tea drying equipment needs to be moved to a sheltered location during rain, the unfolded rainproof tarpaulin will always cover the outside of the equipment. Because the tarpaulin is stably connected to the longitudinal track frame via a U-shaped metal slide, it will not fall off due to equipment shaking or external force during movement. This continuously prevents rainwater from directly falling onto the tea leaves placed on the drying trays, ensuring that the tea leaves are always protected from rain when tea farmers move the equipment to harvest in the rain. This avoids secondary impacts on tea quality caused by rainwater during the harvesting process, further enhancing the reliability of tea protection under sudden weather conditions. When the weather clears up, there is no need for further protection. When the rainproof tarpaulin is retracted, simply pull the U-shaped metal slide backward. The U-shaped metal slide, rainproof tarpaulin, and U-shaped metal fixing frame are all located behind the tea drying device. The advantage of this rear-mounted retraction design is that it will not obstruct the tea drying trays on the drying tray placement frames A and B after retraction, ensuring that the tea can receive sufficient sunlight and will not affect the normal operation of the drying process. At the same time, the device occupies little space when retracted and will not interfere with the placement and use of adjacent tea drying devices, making it suitable for the dense layout requirements of large-scale drying sites.

[0022] 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.

[0023] This utility model provides, for example Figure 1-4The device shown is a tea drying apparatus for uniform drying. Its core design focuses on layered drying, stable support, and timely rain protection. Through optimized frame layout and protective structure, it achieves uniform drying of tea leaves while responding to sudden rain and fog, adapting to the needs of large-scale tea drying operations. Four vertical supports 2, arranged in a rectangular pattern, are the core supporting components of the apparatus. They are made of high-strength carbon steel and must be able to support the frame holding the drying trays 4, the tea leaves placed on the trays, and the weight of the tea leaves, ensuring the apparatus remains undeformed during long-term outdoor use. The four vertical supports 2 are interconnected near the top by top reinforcing rods 6 and near the bottom by bottom reinforcing rods 3. This double-reinforcement design at the top and bottom forms a rectangular stable frame through the top reinforcing rods 6 and bottom reinforcing rods 3. The frame disperses the lateral forces (such as wind force and impact force during movement) on the vertical support 2, preventing the vertical support 2 from tilting or collapsing, improving the overall structural stability of the device, and is suitable for outdoor use scenarios with strong winds and frequent movement. Each of the four vertical supports 2 has a wheel plate welded to its bottom, and the bottom of the wheel plate is fixed with a moving wheel 1 by screws. The moving wheel 1 is a universal wheel with a built-in braking function. The design principle of the moving wheel 1 is that the universal wheel structure can achieve 360-degree rotation, which makes it easy for the device to move flexibly in the drying area (such as adjusting the drying position to match the angle of the sun). It is especially suitable for the layout adjustment of large-area drying areas. The built-in braking function can lock the wheel body by stepping on the brake after the device moves to the target position, preventing the device from sliding due to ground tilt or wind force, ensuring the stability of the tea placed on the drying tray 4, and preventing the tea from spilling.

[0024] like Figure 1 and Figure 2 As shown, the lower sides of the four vertical supports 2 are fixedly connected to the drying tray mounting frame A5, and the upper sides are fixedly connected to the drying tray mounting frame B9. Both are fixed horizontally. The principle of its layered design is to increase the drying area within a limited space, while the distance between the upper and lower layers ensures air circulation and prevents the lower layer of tea leaves from being blocked by the upper layer, ensuring that both the upper and lower layers of tea leaves can receive sufficient sunlight. The horizontal fixation prevents the tea leaves from tilting when placed on the drying tray 4, and prevents the tea leaves from piling up to one side due to gravity, ensuring that the tea leaves are evenly distributed during the drying process, thus achieving the core requirement of even drying. The drying tray mounting frame A5 and the drying tray mounting frame B9 are fixedly connected to the lower sides of the four vertical supports 2. The interior of the tray-laying frame B9 is equipped with multiple placement baffles 7 at equal intervals from left to right, and the frame and the top outer wall of the placement baffles 7 are flush. The design principle of the placement baffles 7 is twofold: first, to limit and prevent slippage, the gap formed by adjacent placement baffles 7 can limit the tea-drying tray 4 laterally, preventing the tea-drying tray 4 from sliding laterally due to movement or vibration; second, to assist in load-bearing, the placement baffles 7 and the frame jointly bear the weight of the tea-drying tray 4 and the tea, distributing the pressure and avoiding excessive local stress on the frame that could lead to deformation. At the same time, the flush top outer wall can ensure that the tea-drying tray 4 is placed stably, further ensuring that the tea is dried evenly.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the rain and fog protection device 8 is connected between the left and right vertical supports 2 of the drying tray mounting frame A5. Its core function is to cope with sudden rain and fog. The longitudinal track frame A10 of the rain and fog protection device 8 is set longitudinally on the right side of the two vertical supports 2, and the longitudinal track frame B13 is set longitudinally on the left side of the two vertical supports 2. The two are connected to the outside of the vertical supports 2 by U-shaped fixing sleeves 11 and then fixed with multiple sets of screws. The wrapping fixing principle of the U-shaped fixing sleeves 11 is to increase the contact area with the vertical supports 2, ensure that the longitudinal track frames A10 and B13 are firmly installed, and avoid displacement due to vibration after long-term use. The removable screw fixing facilitates later maintenance and replacement, extending the service life of the device. Both the longitudinal track frame A10 and the longitudinal track frame B13 are equipped with T-shaped anti-detachment grooves 14, and T-shaped anti-detachment sliders 15 are installed in the grooves. The front opening of the T-shaped anti-detachment groove 14 is inserted into the sealing block 12. The design principle of the T-shaped structure is that the lateral protrusion of the T-shaped anti-detachment slider 15 matches the lateral groove of the T-shaped anti-detachment groove 14, preventing the slider from detaching up and down during the sliding process, ensuring stable operation when the U-shaped metal slide 16 drives the rainproof tarpaulin 17. The sealing block 12 can prevent the T-shaped anti-detachment slider 15 from slipping off from the front opening, avoiding the failure of the protective function, and is suitable for outdoor sliding use scenarios.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the U-shaped metal carriage 16 is in an open-down state, with both ends of the opening welded to the tops of two T-shaped anti-detachment sliders 15, and sleeved on the left and right sides and the top exterior of the device. A U-shaped metal fixing frame 18 is fixed to the rear ends of the longitudinal track frame A10 and the longitudinal track frame B13, with a rainproof tarpaulin 17 fixed between them. When it rains, pushing the U-shaped metal carriage 16 causes the T-shaped anti-detachment sliders 15 to slide forward in the T-shaped anti-detachment groove 14 until they are blocked by the sealing block 12. At this time, the rainproof tarpaulin 17 is fully unfolded, covering the left side of the device. The right sides and top form a closed protective space to prevent rainwater from directly hitting the tea leaves on the drying tray 4. After the weather clears up, the U-shaped metal slide 16 is pulled back, and the rainproof tarpaulin 17 is simultaneously retracted. Finally, the U-shaped metal slide 16, the rainproof tarpaulin 17, and the U-shaped metal fixing frame 18 are all located at the rear of the device, without obstructing the tea leaves on the drying tray 4, ensuring that the drying operation can proceed normally. This design achieves rapid rain protection while also taking into account the drying needs. Protection can be completed without moving the device, greatly improving the efficiency of responding to sudden weather events.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
