Description

Technical Field

[0001] This application relates to the field of tea processing technology, and in particular to an adjustable tea drying rack. Background Technology

[0002] Tea leaf spreading is a tea processing step in which freshly picked tea leaves are spread out in a certain thickness and dried in the sun. This process allows the moisture in the different parts of the leaves to be redistributed evenly, dissipates heat between the leaves, and reduces the rate of water loss and chemical changes. It plays an important role in ensuring the quality of tea processing and is also a necessary condition for subsequent processing steps.

[0003] A related technology proposes a tea-drying device, including a support frame, a movable frame, and placement frames. The movable frames are vertically spaced on the support frame and slidably connected to the support frame laterally. Each movable frame is equipped with a drive mechanism for sliding itself. Placement frames are mounted on each movable frame. In use, the tea leaves are evenly spread on the placement frames, and then the drive mechanism moves the movable frames, arranging the placement frames in a stepped structure. This allows the tea leaves to receive more uniform sunlight, improving the drying effect.

[0004] Regarding the aforementioned technologies, the height of each mobile rack is fixed, making it inconvenient to turn over and dry the tea leaves placed on the high racks during use. This results in low flexibility and inconvenience in use. Utility Model Content

[0005] To address the issues of fixed heights in various movable racks, which make it inconvenient to turn over and dry tea leaves placed on higher racks, resulting in low flexibility and inconvenience, this application provides an adjustable tea drying rack.

[0006] The adjustable tea drying rack provided in this application adopts the following technical solution:

[0007] An adjustable tea drying rack includes a support frame, sliding seats, and a drying mesh plate. The support frame includes a base plate and diagonal rods. The diagonal rods are rotatably connected to the base plate. The sliding seats are slidably connected to the diagonal rods along their length. Multiple sliding seats are provided. The support frame is provided with a drive mechanism for adjusting the spacing between the sliding seats. The drying mesh plate is provided on each sliding seat. The support frame is provided with an adjustment mechanism for adjusting the tilt angle of the diagonal rods.

[0008] By adopting the above technical solution, during use, the spreading mesh is installed on the sliding seat, and the tea leaves are placed on the spreading mesh. Then, the distance between each sliding seat is adjusted by the drive mechanism, so that the spreading mesh is distributed in a stepped manner with a certain spacing. The tea leaves on each spreading mesh can receive sufficient sunlight, resulting in a better spreading effect. This improves the problem of the fixed height of each moving frame in the existing technology, which makes it inconvenient to turn the tea leaves placed on the higher racks during use, resulting in low flexibility and inconvenience. At the same time, the adjustment mechanism can adaptively adjust the tilt angle of the inclined rod, so that the tea leaves on the spreading mesh can adapt to the angle of sunlight, further improving the spreading effect.

[0009] Optionally, the drive mechanism includes a rotating pin, a first connecting rod, and a second connecting rod. The rotating pin is disposed on each sliding seat. The middle parts of the first connecting rod and the second connecting rod are rotatably connected to the rotating pin. The two ends of the first connecting rod on the sliding seat are respectively rotatably connected to the ends of the second connecting rod on the adjacent sliding seat. The inclined rod is provided with a drive component for driving the ends of the first connecting rod and the second connecting rod on the bottommost sliding seat to move closer or further apart from each other.

[0010] By adopting the above technical solution, the driving component drives the ends of the first and second connecting rods on the bottom sliding seat to move closer or further apart. Since the middle of the first and second connecting rods on each sliding seat is rotatably connected by a rotating pin, and the two ends of the first connecting rod on one sliding seat are respectively rotatably connected to the ends of the second connecting rods on the adjacent sliding seat, each sliding seat can slide synchronously along the length of the inclined rod, thereby adjusting the distance between each sliding seat, which makes it convenient to change the distance between the spreading mesh boards according to actual needs.

[0011] Optionally, the drive assembly includes a slide groove, a first slider, a second slider, a double-ended lead screw, and a rotating handwheel. The slide groove is disposed on an inclined rod, and the first slider and the second slider are slidably connected within the slide groove. The double-ended lead screw is rotatably connected to the slide groove, and both ends of the double-ended lead screw pass through the first slider and the second slider respectively and are threadedly connected to the first slider and the second slider. The rotating handwheel is disposed at the end of the double-ended lead screw. The end of the first connecting rod on the bottommost sliding seat is rotatably connected to the first slider, and the end of the second connecting rod on the bottommost sliding seat is rotatably connected to the second slider.

[0012] By adopting the above technical solution, rotating the handwheel can drive the double-ended lead screw to rotate. Since the two ends of the double-ended lead screw are respectively threaded to the first slider and the second slider, and the first slider and the second slider are slidably connected in the groove on the inclined rod, the rotation of the double-ended lead screw will cause the first slider and the second slider to move closer or further apart in the groove, thereby causing the ends of the first connecting rod and the second connecting rod on the bottom sliding seat to move closer or further apart. Through the transmission of the first connecting rod and the second connecting rod, the distance between each sliding seat can be adjusted. The double-ended lead screw has self-locking property, which can ensure the stability of the adjustment of the distance between the first slider and the second slider. The structure is relatively simple and the adjustment is convenient.

[0013] Optionally, the bottom of the drying rack is provided with an insert block, and each of the sliding seats is provided with a slot at the top. The insert block is inserted into the slot, and the sliding seat is provided with an anti-detachment component to prevent the insert block from coming out of the slot.

[0014] By adopting the above technical solution, an insert block is set at the bottom of the drying mesh plate and a slot is opened at the top of the sliding seat. The insert block is inserted into the slot, which facilitates the installation of the drying mesh plate onto the sliding seat. The anti-detachment component is set to prevent the insert block from coming out of the slot, which can ensure the stability of the connection between the drying mesh plate and the sliding seat and realize the detachable connection between the drying mesh plate and the sliding seat.

[0015] Optionally, the anti-detachment component includes a rod and a return spring. The rod is inserted into the sliding seat, and the insert block has an anti-detachment hole. The rod is inserted into the anti-detachment hole. One end of the return spring is connected to the sliding seat, and the other end of the return spring is connected to the rod. The return spring tends to insert the rod into the anti-detachment hole.

[0016] By adopting the above technical solution, after the plug is inserted into the slot, the return spring is used to insert the plug rod into the anti-dislodgement hole, which can prevent the plug from coming out of the slot, thereby making the drying mesh plate stably installed on the sliding seat.

[0017] Optionally, the adjusting mechanism includes a worm gear, a worm, and a rotating handle. The inclined rod is rotatably connected to the base plate via the rotating rod. The worm gear is coaxially connected to the rotating rod. The worm is rotatably connected to the base plate. The worm meshes with the worm gear. The rotating handle is located at the end of the worm.

[0018] By adopting the above technical solution, rotating the rotating handle drives the worm to rotate. Since the worm meshes with the worm wheel, the worm wheel rotates. The worm wheel is coaxially connected to the rotating rod, which in turn drives the rotating rod to rotate. Since the inclined rod is rotatably connected to the base plate through the rotating rod, the tilt angle of the inclined rod is finally adjusted. By utilizing the self-locking property of the worm gear transmission, the stability of the tilt angle adjustment of the inclined rod can be achieved.

[0019] Optionally, the bottom of the base plate is provided with rollers, and the inclined rod is provided with a handle parallel to the base plate.

[0020] By adopting the above technical solution, rollers are installed at the bottom of the base plate and grips are installed on the inclined rod parallel to the base plate, which makes it easy to move the adjustable tea drying rack and improves the flexibility of the drying device's location.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The coordinated arrangement of the support frame, sliding seats, spreading screens, and drive mechanism, and the adjustment of the spacing between each sliding seat, allows the spreading screens to be distributed in a stepped manner with a certain spacing. This ensures that the tea leaves on each spreading screen can receive sufficient sunlight, resulting in a better spreading effect. This improves upon the problem in the existing technology where the height of each moving frame is fixed, making it inconvenient to turn over the tea leaves placed on the high-level frames during use, resulting in low flexibility and inconvenience.

[0023] 2. The arrangement of the slide groove, the first slider, the second slider, the double-ended lead screw, and the rotating handwheel allows the rotation of the double-ended lead screw by rotating the handwheel to synchronously drive the ends of the first and second connecting rods on the bottom sliding seat to move closer or further apart. The structure is relatively simple and easy to adjust.

[0024] 3. The adjustment mechanism includes a worm gear, a worm, and a rotating handle. Rotating the rotating handle drives the worm to rotate, which in turn drives the worm gear to rotate, thereby adjusting the tilt angle of the inclined rod. The self-locking property of the worm gear transmission ensures the stability of the tilt angle adjustment. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses an adjustable tea drying rack. (See also...) Figure 1 The adjustable tea drying rack includes a support frame 1, a sliding seat 2, and a drying mesh 3. The support frame 1 includes a base plate 11 and diagonal braces 12. The base plate 11 is a flat structure, made of materials such as metal or wood, possessing a certain strength and stability, used to support the entire drying rack. The bottom of the base plate 11 is equipped with self-locking universal casters 13. Two sets of diagonal braces 12 are symmetrically arranged. The diagonal braces 12 are made of metal, such as stainless steel or aluminum alloy, to ensure their strength and durability. A rotating rod 4 is horizontally fixed at the bottom of each diagonal brace 12, rotating around its own axis and connected to the base plate 11. The support frame 1 is equipped with an adjustment mechanism for adjusting the tilt angle of the diagonal braces 12. The tops of both diagonal braces 12 are connected to a handle 5 parallel to the base plate 11. The handle 5, in conjunction with the casters 13, allows for flexible adjustment of the position of the support frame 1. Two inclined rods 12 are provided with sliding slots on one side close to each other. The two ends of the sliding seat 2 are respectively slidably locked in the sliding slots of the two inclined rods 12. Multiple sliding seats 2 are provided along the length of the inclined rods 12. The drying net plate 3 is respectively provided on each sliding seat 2. The support frame 1 is provided with a drive mechanism for adjusting the distance between each sliding seat 2.

[0032] In use, the spreading mesh 3 is installed on the sliding seat 2, and the tea leaves are placed on the spreading mesh 3. Then, the distance between the sliding seats 2 is adjusted by the drive mechanism, so that the spreading mesh 3 is distributed in a stepped manner with a certain spacing. The tea leaves on each spreading mesh 3 can receive sufficient sunlight, resulting in a better spreading effect. When it is necessary to turn the tea leaves at higher positions, the height of the higher spreading mesh 3 can be lowered simply by reducing the distance between the sliding seats 2 by the drive mechanism. This improves upon the problem of fixed height of each moving frame in the prior art, which makes it inconvenient to turn the tea leaves in the higher positions, resulting in low flexibility and inconvenience. At the same time, the adjustment mechanism can adaptively adjust the tilt angle of the inclined rod 12, so that the tea leaves on the spreading mesh 3 can be oriented towards the sunlight angle, further improving the spreading effect.

[0033] For example, the driving mechanism includes a rotating pin 21, a first connecting rod 22, and a second connecting rod 23. The rotating pin 21 is vertically welded and fixed to the bottom of each sliding seat 2. The middle parts of the first connecting rod 22 and the second connecting rod 23 are rotatably connected to the rotating pin 21. The two ends of the first connecting rod 22 on the sliding seat 2 are rotatably connected to the ends of the second connecting rod 23 on the adjacent sliding seat 2, respectively. The inclined rod 12 is provided with a driving component for driving the ends of the first connecting rod 22 and the second connecting rod 23 on the bottommost sliding seat 2 to move closer or further apart. The driving component drives the ends of the first connecting rod 22 and the second connecting rod 23 on the bottommost sliding seat 2 to move closer or further apart. Since the middle parts of the first connecting rod 22 and the second connecting rod 23 on each sliding seat 2 are rotatably connected by the rotating pin 21, and the two ends of the first connecting rod 22 on one sliding seat 2 are rotatably connected to the ends of the second connecting rod 23 on the adjacent sliding seat 2, each sliding seat 2 can slide synchronously along the length direction of the inclined rod 12. While driving each sliding seat 2 to rise, the distance between each sliding seat 2 is adjusted. The structure is simple and easy to use.

[0034] Specifically, the drive assembly includes a slide groove 24, a first slider 25, a second slider 26, a double-ended lead screw 27, and a rotating handwheel 28. The slide groove 24 is welded and fixed to the inclined rod 12 in a horizontal direction. The first slider 25 and the second slider 26 are slidably connected within the slide groove 24. The double-ended lead screw 27 is rotatably connected to the slide groove 24, with its two ends passing through the first slider 25 and the second slider 26 respectively and threadedly connected to them. The rotating handwheel 28 is welded and fixed to the end of the double-ended lead screw 27. The end of the first connecting rod 22 on the bottommost sliding seat 2 is rotatably connected to the first slider 25, and the end of the second connecting rod 23 on the bottommost sliding seat 2 is rotatably connected to the second slider 26. The slide groove 24 is generally a long strip-shaped groove used to limit the sliding direction of the first slider 25 and the second slider 26. The first slider 25 and the second slider 26 are block-shaped structures whose shapes are adapted to the slide groove 24, allowing them to slide within the slide groove 24. The threads at both ends of the double-ended lead screw 27 turn in opposite directions. When the handwheel 28 is turned, the double-ended lead screw 27 rotates, causing the first slider 25 and the second slider 26 to move closer or further apart in the slide groove 24. This drives the ends of the first connecting rod 22 and the second connecting rod 23 on the bottom sliding seat 2 to move closer or further apart, thereby adjusting the spacing between each sliding seat 2.

[0035] For example, refer to Figure 1-2 The adjusting mechanism includes a worm gear 41, a worm 42, and a rotating handle 43. The worm gear 41 is coaxially fixedly connected to the rotating rod 4, and the worm 42 is rotatably connected to the base plate 11, meshing with the worm gear 41. The rotating handle 43 is located at the end of the worm 42. When the rotating handle 43 is rotated, the worm 42 rotates, driving the worm gear 41 to rotate, thereby causing the rotating rod 4 to rotate, thus adjusting the tilt angle of the inclined rod 12. Due to the self-locking property of the transmission between the worm gear 41 and the worm 42, the stability of the tilt angle adjustment of the inclined rod 12 can be achieved.

[0036] In addition, refer to Figure 3 The bottom of the drying rack 3 is fixedly equipped with an insert block 31. Each sliding seat 2 has a slot 29 on its top that matches the shape of the insert block 31. The insert block 31 is inserted into the slot 29. The sliding seat 2 is equipped with an anti-detachment component to prevent the insert block 31 from falling out of the slot 29. The insertion of the insert block 31 into the slot 29 realizes the detachable connection between the drying rack 3 and the sliding seat 2. The anti-detachment component further improves the stability of the connection and reduces the risk of the drying rack 3 falling off during the movement of the sliding seat 2.

[0037] Specifically, the anti-detachment component includes a rod 6 and a return spring 7. The rod 6 is inserted into the sliding seat 2, and the insert block 31 has an anti-detachment hole, into which the rod 6 is inserted. One end of the return spring 7 is connected to the sliding seat 2, and the other end is connected to the rod 6. The return spring 7 tends to insert the rod 6 into the anti-detachment hole. The rod 6 is generally a rod-shaped structure with a diameter that matches the anti-detachment hole, allowing it to be inserted into the hole. The return spring 7 is a helical spring. When the rod 6 is inserted into the anti-detachment hole, the return spring 7 is in its normal state, preventing the insert block 31 from coming out of the slot 29. When it is necessary to remove the drying rack 3, the rod 6 is pulled outward to compress the return spring 7, causing the rod 6 to disengage from the anti-detachment hole, allowing the drying rack 3 to be removed from the sliding seat 2. The installation and removal of the drying rack 3 is relatively convenient.

[0038] The implementation principle of the adjustable tea drying rack in this application embodiment is as follows: In use, the drying rack 3 is installed on the sliding seat 2 and the tea is placed on the drying rack 3. Then, the rotating handwheel 28 drives the double-headed screw 27 to rotate, which in turn drives the first slider 25 and the second slider 26 to move closer to each other. This causes the ends of the first connecting rod 22 and the second connecting rod 23 on the bottom sliding seat 2 to move closer to each other, making the included angle between the first connecting rod 22 and the second connecting rod 23 smaller. This allows the distance between the sliding seats 2 to increase while the sliding seats 2 are raised, so that the drying rack 3 is distributed in a stepped manner with a certain spacing. The tea on each drying rack 3 can receive sufficient sunlight, resulting in a better drying effect. This improves the problem of the fixed height of each moving rack in the prior art, which makes it inconvenient to turn the tea placed on the rack at a high position during use, resulting in low flexibility and inconvenience. Meanwhile, during the spreading and drying process, the rotating handle 43 is rotated in a timely manner, which drives the rotating rod 4 to rotate under the transmission action of the worm gear 41 and worm 42, thereby adjusting the tilt angle of the inclined rod 12, so that the tea leaves on the spreading mesh plate 3 can adapt to the angle of sunlight, further improving the spreading and drying effect.

[0039] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
