Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a drying device for green tea. Background Art

[0002] Green tea is processed through processes such as steaming, frying, rolling, and drying. Compared with black tea, green tea does not undergo fermentation during the production process, so most of the natural components in the tea leaves, such as tea polyphenols, are retained. During the drying process of green tea, a dryer needs to be used for operation.

[0003] In the prior art, a patent document with the publication number CN215676136U appears. This patent document discloses a green tea dryer, including a main body. A drying area is provided inside the main body. An activity area is provided on the middle side of the drying area. A heat conduction plate is movably installed at the bottom of the activity area. A rotating hole is provided at the rear side of the heat conduction plate. A rotating rod is movably installed inside the rotating hole. The heat conduction plate is movably connected with a pressing plate through the rotating rod. In this kind of green tea dryer, heat is transferred to the materials on it through the heat conduction plate for drying. Then, an air suction pump will suck air inside, and the heat in the upper part of the drying area will be sucked into the guiding pipe through the suction cup. The water vapor inside the guiding pipe will pass through the fixing block and the absorbent cotton inside the fixing block to absorb the water vapor, preventing the water vapor from entering the drying area again. The hot air will enter the lower part of the drying area, thus achieving the purpose of heat recovery and utilization and comprehensive drying.

[0004] The above and prior arts have the following defects: During the drying process of green tea, the green tea is placed between the heat conduction plate and the pressing plate. Since the green tea is pressed, it is difficult to make different parts of the green tea come into uniform contact with hot air, resulting in uneven drying of the green tea and reducing the practicability of the dryer.

[0005] Therefore, a drying device for green tea is proposed. Summary of the Utility Model

[0006] The purpose of the present utility model is to solve the defect that since the green tea is pressed, it is difficult to make different parts of the green tea come into uniform contact with hot air, and a drying device for green tea is proposed.

[0007] To achieve the above object, the utility model adopts the following technical solution: A drying device for green tea, comprising a drying box, wherein an electric heating rod is fixedly connected to the inner wall of the drying box, a plurality of air inlet holes are formed in the side wall of the drying box, an exhaust fan is fixedly connected to the inner wall of the drying box, and a vibration structure is arranged on the inner wall of the drying box. The vibration structure includes a groove formed in the inner wall of the drying box. A cover plate is slidably connected to the inner wall of the groove, a bracket is slidably connected to the inner wall of the groove, a tray is slidably connected to the surface of the bracket, the size of the cover plate is adapted to the size of the tray, a motor is fixedly connected to the outer wall of the drying box, an output end of the motor is fixedly connected to a transmission rod, the transmission rod is rotatably connected to the drying box, a cam is fixedly connected to the arc surface of the transmission rod, and a plurality of ventilation holes are formed in the surfaces of the cover plate and the tray.

[0008] The effect achieved by the above components is that when drying green tea, with the continuous rotation of the output end of the motor, the tray and the cover plate can be continuously vibrated, so that the green tea can fully and evenly contact with the hot air, and thus the green tea can be dried evenly, improving the practicability of the dryer.

[0009] Preferably, a spring is fixedly connected to the inner wall of the groove, and one end of the spring is fixedly connected to the cover plate.

[0010] The effect achieved by the above components is that the cover plate can slide downward by the elastic force of the spring to cover the tray.

[0011] Preferably, a fixing rod is fixedly connected to the side wall of the cover plate, a hook is rotatably connected to the arc surface of the fixing rod, a fixing block is fixedly connected to the surface of the tray, and the hook is engaged with the fixing block.

[0012] The effect achieved by the above components is that by engaging the hook with the fixing block, the hook restricts the position of the fixing block, thereby restricting the position of the tray, and further ensuring the close contact between the cover plate and the tray.

[0013] Preferably, a torsion spring is sleeved on the arc surface of the fixing rod, and two ends of the torsion spring are respectively fixedly connected to the hook and the cover plate.

[0014] The effect achieved by the above components is that the torsion spring can prevent the hook and the fixing block from being separated due to vibration by its own torsion force.

[0015] Preferably, a rotating plate is rotatably connected to the inner wall of the drying box.

[0016] The effect achieved by the above components is that when the rotating plate rotates to the lower side of the cover plate, the rotating plate restricts the position of the cover plate.

[0017] Preferably, a roller is rotatably connected to the lower surface of the bracket, and the roller is slidably connected to the cam.

[0018] The effect achieved by the above components is that the roller reduces the friction between the cam and the bracket.

A plurality of leaf springs are fixedly connected to the surface of the round rod, and one end of the leaf spring is fixedly connected to the bracket.

[0020] The effect achieved by the above components is that when the leaf spring contracts, the round rod will drive the round plate to slide by means of the pulling force of the leaf spring, and the sliding of the round plate will drive the tray to move, so that the tray is moved away from below the cover plate, facilitating the removal of the tray to transfer the green tea.

[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0022] In the present utility model, by providing a vibration structure, when drying the green tea, as the output end of the motor continuously rotates, the tray and the cover plate can be continuously vibrated, so that the green tea can fully and evenly contact with the hot air, and thus the green tea can be evenly dried, improving the practicability of the dryer.

Detailed implementation

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0031] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0032] As Figures 1-6 shown, the present invention provides a drying device for green tea, including a drying box 1, an electric heating rod 2 is fixedly connected to the inner wall of the drying box 1, a plurality of air inlet holes 3 are opened on the side wall of the drying box 1, an exhaust fan 4 is fixedly connected to the inner wall of the drying box 1, and a vibration structure 5 is arranged on the inner wall of the drying box 1. The vibration structure 5 includes a groove 501, the groove 501 is opened on the inner wall of the drying box 1, a cover plate 502 is slidably connected to the inner wall of the groove 501, a bracket 503 is slidably connected to the inner wall of the groove 501, a tray 504 is slidably connected to the surface of the bracket 503, the size of the cover plate 502 is adapted to the size of the tray 504, a motor 505 is fixedly connected to the outer wall of the drying box 1, an output end of the motor 505 is fixedly connected to a transmission rod 506, the transmission rod 506 is rotatably connected to the drying box 1, a cam 507 is fixedly connected to the arc surface of the transmission rod 506, a plurality of ventilation holes are opened on the surfaces of the cover plate 502 and the tray 504, a spring 508 is fixedly connected to the inner wall of the groove 501, one end of the spring 508 is fixedly connected to the cover plate 502, and the cover plate 502 can slide downward by the elastic force of the spring 508 to cover the tray 504. A fixed rod 509 is fixedly connected to the side wall of the cover plate 502, a hook 510 is rotatably connected to the arc surface of the fixed rod 509, a fixed block 511 is fixedly connected to the surface of the tray 504, and the hook 510 is engaged with the fixed block 511. By engaging the hook 510 with the fixed block 511, the hook 510 reaches the position of restricting the fixed block 511, thereby restricting the position of the tray 504, and further ensuring the effect that the cover plate 502 and the tray 504 can be in close contact.

[0033] AsFigures 2-6 As shown, a torsion spring 512 is sleeved on the arc surface of the fixed rod 509. The two ends of the torsion spring 512 are respectively fixedly connected to the hook 510 and the cover plate 502. The torsion spring 512 can prevent the hook 510 and the fixed block 511 from disengaging due to vibration by means of its own torsion force. A rotating plate 513 is rotatably connected to the inner wall of the drying box 1. After the rotating plate 513 rotates to the lower side of the cover plate 502, the rotating plate 513 plays a role in restricting the position of the cover plate 502. A roller 514 is rotatably connected to the lower surface of the bracket 503. The roller 514 is slidably connected to the cam 507. The roller 514 plays a role in reducing the friction force between the cam 507 and the bracket 503. A round rod 515 is slidably connected in the bracket 503. One end of the round rod 515 is fixedly connected to a round plate 516. The round plate 516 is slidably connected to the tray 504. A plurality of leaf springs 517 are fixedly connected to the surface of the round rod 515. One end of the leaf spring 517 is fixedly connected to the bracket 503. When the leaf spring 517 contracts, the round rod 515 will drive the round plate 516 to slide by means of the pulling force of the leaf spring 517. The sliding of the round plate 516 will drive the tray 504 to move, so that the tray 504 is moved away from the lower side of the cover plate 502, facilitating the removal of the tray 504 to transfer the green tea.

[0034] The overall working principle is as follows. When it is necessary to dry green tea, place the green tea in the tray 504, then lift the cover plate 502 upward. As the cover plate 502 slides along the inner wall of the groove 501, the spring 508 will be compressed. After the cover plate 502 moves to an appropriate position, rotate the rotating plate 513. When the rotating plate 513 rotates under the cover plate 502, the rotating plate 513 plays a role in restricting the position of the cover plate 502. Then place the tray 504 on the bracket 503. The tray 504 will squeeze the round plate 516, causing the round plate 516 to abut against the surface of the bracket 503. The movement of the round plate 516 will drive the round rod 515 to move. At this time, the leaf spring 517 will be stretched. Then rotate the rotating plate 513 in the reverse direction. When the rotating plate 513 is disengaged from the cover plate 502, the cover plate 502 will slide downward by the elastic force of the spring 508 to cover the tray 504. Then engage the hook 510 with the fixed block 511. The hook 510 restricts the position of the fixed block 511, thereby restricting the position of the tray 504, and further ensuring that the cover plate 502 and the tray 504 can be in close contact. The torsion spring 512 can prevent the hook 510 and the fixed block 511 from being disengaged due to vibration by virtue of its own torsion. Then turn on the motor 505, the exhaust fan 4 and the electric heating rod 2. The exhaust fan 4 will discharge the air in the drying box 1, so that the outside air can flow into the drying box 1 through the air inlet hole 3. At this time, the electric heating rod 2 will heat the flowing air, and then dry the green tea with the hot air. At the same time, the rotation of the output end of the motor 505 will drive the rotating rod to rotate. The rotation of the transmission rod 506 will drive the cam 507 to rotate. When the cam 507 rotates, it will first squeeze the roller 514, causing the roller 514 to slide upward. The movement of the roller 514 will drive the bracket 503 to move upward. The roller 514 plays a role in reducing the friction between the cam 507 and the bracket 503. The bracket 503 will drive the tray 504 and the cover plate 502 to move synchronously. At this time, the spring 508 will be compressed again. When the cam 507 continues to rotate and is disengaged from the roller 514, the spring 508 will stretch again, and the cover plate 502 will drive the tray 504 to slide downward rapidly. Therefore, as the output end of the motor 505 continues to rotate, the tray 504 and the cover plate 502 can be continuously vibrated, so that the green tea can be fully and evenly contacted with the hot air, and then the green tea can be dried evenly. After the drying operation of the green tea is completed, rotate the hook 510 again to disengage the hook 510 from the fixed block 511. At this time, the leaf spring 517 begins to contract. The round rod 515 will drive the round plate 516 to slide by the pulling force of the leaf spring 517. The sliding of the round plate 516 will drive the tray 504 to move, so that the tray 504 is moved away from under the cover plate 502, which is convenient for taking out the tray 504 to transfer the green tea.

[0035] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the protection scope of the technical solution of the present utility model.
