DETAILED DESCRIPTION

[0024] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific embodiments.

[0025] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on the present application; in order to better illustrate the embodiments of the present utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0026] Example: Figure 1-Figure 8 As shown, a black tea drying device comprises a mounting seat 101, a drying box 102 is mounted on the mounting seat 101, a sealing door 103 is arranged on the drying box 102, a rotating shaft 109 is mounted on the drying box 102, a plurality of drying components are arranged on the rotating shaft 109, a control component is arranged on the mounting seat 101, and the control component is transmission-connected with the rotating shaft 109; the drying component comprises a drying plate 106 and a tea scraps collecting plate 107, the drying plate 106 and the tea scraps collecting plate 107 are connected to each other. The plates 107 are arranged with a spacing, and the cross-sections of the drying plate 106 and the tea debris collecting plate 107 are both arc-shaped, with the arc opening facing upward. The tea debris collecting plate 107 collects the tea debris that falls from the drying plate 106, and an electric heating plate is arranged on the tea debris collecting plate 107; the control component can drive the rotating shaft 109 to rotate unidirectionally or vibrate longitudinally. When the rotating shaft 109 rotates, the tea leaves on the drying plate 106 begin to spread and dry under the action of centrifugal force; when the rotating shaft 109 vibrates, the tea leaves roll and gather at the bottom of the drying plate 106.

[0027] The tea leaves are placed on the drying tray 106. When the control component drives the rotating shaft 109 to rotate, the tea leaves are dispersed on the drying tray 106 under the action of centrifugal force. The electric heating plate on the tea scrap collecting tray 107 is connected to an external power supply and starts to heat and dry the tea leaves. After the rotating shaft 109 rotates for a certain period of time, the control component drives the rotating shaft 109 to vibrate longitudinally. At this time, the tea leaves begin to tumble and gather at the bottom of the drying tray 106 under the action of vibration, and the debris falls on the tea scrap collecting tray 107 and is temporarily collected, thereby completing the turning of the tea leaves. After that, the control component continues to drive the rotating shaft 109 to rotate, and the gathered tea leaves begin to disperse and dry again. Until the drying is completed, the sealing door 103 is opened at this time, the tea leaves in the drying tray 106 are taken out, and then the sealing door 103 is closed. The control component drives the rotating shaft 109 to rotate, and the speed is increased. At this time, the centrifugal force becomes larger, and the debris in the tea scrap collecting tray 107 begins to be thrown out and falls on the bottom of the drying box 102.

[0028] By providing an arc-shaped drying plate 106 and a tea debris collection plate 107 in conjunction with a control component, the tea leaves on the drying plate 106 can reduce the generation of debris when being turned over, and the debris can be automatically separated and collected from the tea leaves; at the same time, the turning operation is completed in a closed space, which can minimize heat loss.

[0029] like Figure 4 As shown, a limiting ring 122 is installed on the drying plate 106. By providing the limiting ring 122, after the drying is completed, the rotation speed of the rotating shaft 109 can be directly increased without opening the sealing door 103 to take out the tea leaves. At this time, due to the effect of the limiting ring 122, the tea leaves cannot be thrown out, but the debris will be thrown out of the tea debris collection plate 107, and then the sealing door 103 can be opened to take out the tea leaves, thereby improving the working efficiency.

[0030] like Figure 6-Figure 8 As shown, the control component includes a bracket 118 fixedly connected to the mounting base 101 and a transmission disk 114 rotatably connected to the drying box 102, the bracket 118 is rotatably connected to the second gear 117, the mounting base 101 is installed with a motor 115, the motor 115 is connected to a first gear 116, the first gear 116 is meshed with the second gear 117, a plurality of protrusions 120 are arranged on the second gear 117, an adjusting disk 119 is slidably connected to the transmission disk 114, a spring 121 is arranged between the transmission disk 114 and the adjusting disk 119, the adjusting disk 119 is fixedly connected to the rotating shaft 109, and the adjusting disk 119 cooperates with the protrusion 120.

[0031] When the motor 115 rotates forward, the first gear 116 drives the second gear 117. At this time, the protrusion 120 vertically pushes the convex sliders around the adjusting disk 119, and the adjusting disk 119 makes the rotating shaft 109 and the transmission disk 114 rotate synchronously; when the motor 115 rotates reversely, the first gear 116 drives the second gear 117. At this time, the inclined surface of the protrusion 120 squeezes the convex sliders around the adjusting disk 119, the spring 121 begins to be compressed, the adjusting disk 119 moves upward, and the protrusion 120 begins to cross the convex slider on the adjusting disk 119, that is, under the action of the protrusion 120 and the spring 121, the adjusting disk 119 drives the rotating shaft 109 to achieve longitudinal vibration, and at this time the transmission disk 114 and the rotating shaft 109 do not rotate.

[0032] like Figure 4 As shown, the driving disc 114 is fixedly connected to the push plate 112, the drying box 102 is provided with a chip removal hole 123, and the mounting seat 101 is provided with a tea chip collection box 105. When the driving disc 114 rotates, the push plate 112 rotates synchronously, and the push plate 112 pushes the tea chips at the bottom of the drying box 102 to the chip removal hole 123, and then the tea chips fall into the tea chip collection box 105 and are collected. Through the above arrangement, the automatic collection of tea chips is completed, and the labor intensity of personnel is reduced.

[0033] like Figure 4 As shown, a scraper 111 is installed on the push plate 112, and the scraper 111 is in contact with the inner wall of the drying box 102. When the push plate 112 rotates, the scraper 111 rotates synchronously, and the scraper 111 scrapes off the tea crumbs that may be adhered to the inner wall of the drying box 102 to ensure the cleanliness of the drying box 102.

[0034] like Figure 2 , Figure 4 As shown, the drying assembly further includes a water collecting tray 108, which is arranged on the side of the tea scraps collecting tray 107 away from the drying tray 106, and the rotating shaft 109 is axially provided with a through hole and radially provided with a plurality of water guide holes 110, the water guide holes 110 cooperate with the water collecting tray 108, and a water collecting box 113 is installed on the mounting seat 101. When the tea leaves are dried, water vapor rises. Due to the arc-shaped setting of the tea scraps collecting tray 107, part of the water vapor may condense after contacting the tea scraps collecting tray 107. At this time, water droplets begin to gather at the bottom of the tea scraps collecting tray 107, and then flow along the outer wall of the rotating shaft 109 into the water collecting tray 108, and then gather into the axial through hole of the rotating shaft 109 through the water guide holes 110, and finally flow into the water collecting box 113 to be collected. Through the above-mentioned setting, the condensed water droplets can be automatically collected and discharged to prevent them from dripping into the tea leaves.

[0035] like Figure 1As shown, an exhaust hole 104 is provided at the top of the drying box 102, and an electric exhaust fan is provided at the exhaust hole 104. Through the electric fan, the water vapor in the drying box 102 can be discharged to accelerate the drying progress of the tea leaves.

[0036] Working principle: personnel open the sealed door 103, put equal amounts of tea leaves on multiple drying trays 106, then close the sealed door 103, start the electric heating plate and motor 115 on the tea debris collection tray 107, the motor 115 first drives the rotating shaft 109 to rotate, at this time, affected by the centrifugal force, the tea leaves in the drying tray 106 are evenly dispersed and begin to be baked by the electric heating plate; part of the evaporated water vapor is discharged by the electric exhaust fan at the exhaust hole 104, and another part is discharged into the water collecting box 113 through the rotating shaft 109 when it encounters the tea debris collection tray 107 condensation; then the motor 115 drives the rotating shaft 109 to vibrate, at this time the tea leaves scattered on the drying tray 106 begin to turn and gather, and the tea debris leaks onto the tea debris collection tray 107; the rotating shaft 109 is controlled to rotate and vibrate periodically to complete the drying of the tea leaves. When the tea leaves are dried, the speed of the motor 115 is increased to speed up the rotation speed of the rotating shaft 109. At this time, the tea leaves in the drying tray 106 are pressed on the limiting ring 122 due to the centrifugal force, and the tea scraps in the tea scraps collecting tray 107 are thrown out of the tea scraps collecting tray 107, hit the inner wall of the drying box 102, and then fall on the bottom of the drying box 102, and the push plate 112 and the scraper 111 push the tea scraps to the transmission plate 114 and fall out, and are collected by the tea scraps collecting box 105; then the motor 115 stops rotating, the electric heating plate on the tea scraps collecting tray 107 is powered off, and the personnel open the sealed door 103 to take out the tea leaves in the drying tray 106.

[0037] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative labor all fall within the protection scope of the present invention.
