Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a large-platform tea drying platform. Background Technology

[0002] Withering tea leaves is a crucial step in tea production, especially for green tea and other non-fermented teas. The purpose of withering is to allow the freshly picked leaves to air dry naturally, reducing moisture and promoting the transformation of substances within the leaves, thus preparing them for subsequent processes such as fixation.

[0003] The existing tea drying platform can be referenced from Chinese Utility Model Patent Publication No. CN213153769U, which discloses a tea drying platform, including a drying platform and a motor fixed to one side of the drying platform. The surface of the drying platform is evenly distributed with ventilation holes. The lower part of the drying platform has an exhaust hood covering the bottom of the drying platform. One side of the exhaust hood has an opening and an exhaust fan is fixed at the opening. The output shaft of the motor is fixed with a screw. A guide rail is fixed to the side of the drying platform. A slider is threaded onto the screw and slides with the guide rail. A bearing is fixed to the side of the slider. The bearing is connected to a rotatable lever. A gear is fixed on the lever. A rack that meshes with the gear is fixed along the length of the drying platform. A paddle is fixed to the outer periphery of the lever. This utility model uses the lever and paddle to easily comb and flatten the tea leaves on the drying platform to ensure that the tea leaves discharged from the tea dryer are quickly air-dried.

[0004] The aforementioned device still has some shortcomings in practical use. While it dissipates heat through exhaust fans and vents, the fixed design of the exhaust fan on the exhaust hood can cause airflow to concentrate in one area rather than being evenly distributed across the entire drying platform. This results in some areas of tea drying too quickly, while other areas remain under-dried, affecting overall uniformity and quality. Utility Model Content

The hot air blower is fixedly connected to the rear side of the outer wall of the protective cover.

[0008] As a preferred embodiment of the large-platform tea drying platform of this utility model, a baffle is fixedly connected to the top of the drying platform, anti-slip pads are fixedly connected to the bottom of each of the support legs, and a controller is fixedly connected to the front side of the protective cover.

[0009] As a preferred embodiment of the large-platform tea drying platform of this utility model, a collection hopper with through holes on its surface is fixedly connected to the top of the inner wall of the protective cover. The diameter of the through holes in the collection hopper is smaller than the diameter of the through holes in the ventilation holes. An inclined discharge pipe is fixedly connected to one side of the bottom of the collection hopper. The end of the discharge pipe away from the collection hopper extends to the front side of the outside of the drying platform and is fixedly connected thereto.

[0010] As a preferred embodiment of the large-platform tea drying platform of this utility model, each of the air blowing boxes is fixedly connected to a threaded block at the bottom, and the inner walls of the two threaded blocks are threaded with a bidirectional threaded rod. The left end of the bidirectional threaded rod is rotatably connected to the left side of the inner wall of the protective cover, and the right end of the bidirectional threaded rod extends to the right side of the outer side of the protective cover and is rotatably connected to it.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model involves starting a hot air blower. The hot air generated by the blower enters the distribution pipe through the air inlet pipe. The distribution pipe evenly distributes the hot air to two elastic telescopic pipes, which then transport the hot air to the air blowing box. From there, the hot air is blown upwards onto the tea leaves on the drying platform through the air blowing pipe. During the blowing and turning process, fine debris and dust from the tea leaves are carried into the collection hopper by the airflow. The diameter of the through-hole in the collection hopper is smaller than the diameter of the air vent, ensuring that only fine debris and dust can enter the collection hopper and do not carry away the tea leaves. The debris and dust entering the collection hopper are discharged to the front of the drying platform through an inclined discharge pipe, keeping the interior clean.

[0017] 2. This utility model uses a power motor to drive a bidirectional threaded rod to rotate. The threaded block moves on the bidirectional threaded rod, causing the air-blowing box to slide inside the protective cover. The airflow distribution is optimized by adjusting its position. The power motor drives a second pulley to rotate via a first pulley and a belt, which in turn drives a reciprocating screw to rotate. When the reciprocating screw rotates, the screw sleeve moves linearly along the reciprocating screw. The guide rod ensures the stable sliding of the screw sleeve. The screw sleeve drives the connecting rod and the turning plate to slide on the top of the drying platform, periodically turning the tea leaves to ensure that the tea leaves are evenly exposed to air and dried.

[0028] The air-blowing box 201 is slidably installed on the left and right sides inside the protective cover 104, and its position can be adjusted by sliding. The air-blowing pipe 202 is fixed to the top of the air-blowing box 201, located below the drying platform 101, and is used to blow airflow onto the tea leaves. The diverter pipe 208 is fixed to the bottom of the inner wall of the protective cover 104 and is used to distribute the airflow. The elastic telescopic pipe 209 connects the diverter pipe 208 and the air-blowing box 201, allowing the air-blowing box 201 to maintain unobstructed airflow when it slides. The air inlet pipe 210 connects the diverter pipe 208 and the hot air blower 211 and is used to deliver hot air. The hot air blower 211 is fixed to the rear side of the outer wall of the protective cover 104 and provides a hot air source.

[0029] The turning mechanism 300 is slidably connected to the top of the drying platform 101 to turn the tea leaves periodically, ensuring that the tea leaves are evenly exposed to air.

[0030] Furthermore, a baffle 103 is fixedly connected to the top of the drying rack 101, and anti-slip pads are fixedly connected to the bottom of the support legs 105. A controller 106 is fixedly connected to the front side of the protective cover 104.

[0033] The collecting hopper 107 is fixed to the top of the inner wall of the protective cover 104, and has through holes on its surface. The diameter of the through holes is smaller than the diameter of the vent holes 102, which are used to collect fine debris and dust from the tea leaves. The discharge pipe 108 is inclined and fixed to one side of the bottom of the collecting hopper 107. The end away from the collecting hopper 107 extends to the front side of the drying platform 101 and is fixedly connected, which is used to discharge the collected debris and dust to the outside.

[0034] Furthermore, each of the air-blowing boxes 201 has a fixed threaded block 203 at its bottom. The inner walls of the two threaded blocks 203 are threaded with a bidirectional threaded rod 204. The left end of the bidirectional threaded rod 204 is rotatably connected to the left side of the inner wall of the protective cover 104, and the right end of the bidirectional threaded rod 204 extends to the right side of the outer side of the protective cover 104 and is rotatably connected to it.

[0035] Furthermore, a power motor 206 is fixedly connected to the right side of the outer wall of the protective cover 104. The output shaft of the power motor 206 is fixedly connected to the right end of the bidirectional threaded rod 204. A pulley 207 is fixedly sleeved on the surface of the bidirectional threaded rod 204 outside the protective cover 104. Horizontal limiting rods 205 are fixedly connected to both the front and rear sides inside the protective cover 104. The threaded block 203 is slidably connected to the horizontal limiting rods 205.

[0036] The power motor 206 drives the bidirectional threaded rod 204 to rotate, and the threaded block 203 moves on the bidirectional threaded rod 204, causing the air blowing box 201 to slide inside the protective cover 104. By adjusting the position, the airflow distribution is optimized. Through the sliding air blowing box 201 and the multi-point distributed air blowing pipe 202, a more uniform airflow distribution can be achieved, avoiding the problem of local drying being too fast or too slow.

[0037] Furthermore, the turning mechanism 300 includes a reciprocating screw 304 rotatably disposed on the rear surface of the drying platform 101. A second pulley 306 is fixedly sleeved on one end of the reciprocating screw 304. A belt 307 is drivenly connected to the surface of the second pulley 306. A first pulley 207 is drivenly connected to the inner wall of the end of the belt 307 away from the second pulley 306.

[0038] Furthermore, a screw sleeve 303 is threadedly connected to the surface of the reciprocating screw 304, and a connecting rod 302 is fixedly connected to the top of the screw sleeve 303. A flipping plate 301 is fixedly connected to the bottom of the end of the connecting rod 302 away from the screw sleeve 303, and the bottom of the flipping plate 301 is slidably connected to the top of the drying table 101.

[0039] The power motor 206 drives the second pulley 306 to rotate through the first pulley 207 and the belt 307, which in turn drives the reciprocating screw 304 to rotate. When the reciprocating screw 304 rotates, the screw sleeve 303 moves linearly along the reciprocating screw 304, which drives the connecting rod 302 and the turning plate 301 to slide on the top of the drying table 101. The turning plate 301 turns the tea leaves periodically to ensure that the tea leaves are evenly exposed to air and dried.

[0040] Furthermore, a guide rod 305 is fixedly connected to the rear surface of the drying rack 101, and the guide rod 305 is slidably connected to the inner wall of the lead screw sleeve 303.

[0041] When in use, the hot air blower 211 is turned on. The hot air generated by the hot air blower 211 enters the distribution pipe 208 through the air inlet pipe 210. The distribution pipe 208 evenly distributes the hot air to the two elastic telescopic pipes 209. The elastic telescopic pipes 209 deliver the hot air to the air blowing box 201, and then blows it upwards onto the tea leaves on the drying platform 101 through the air blowing pipe 202. During the blowing and turning process, fine debris and dust in the tea leaves are carried into the collection hopper 107 by the airflow. The diameter of the through hole in the collection hopper 107 is smaller than the diameter of the through hole in the vent 102, ensuring that only fine debris and dust can enter the collection hopper 107 and will not carry away the tea leaves. The debris and dust entering the collection hopper 107 are discharged to the front of the drying platform 101 through the inclined discharge pipe 108, keeping the inside clean.

[0042] The power motor 206 drives the bidirectional threaded rod 204 to rotate, and the threaded block 203 moves on the bidirectional threaded rod 204, causing the air blowing box 201 to slide inside the protective cover 104. The airflow distribution is optimized by adjusting its position. The power motor 206 drives the second pulley 306 to rotate through the first pulley 207 and the belt 307, which in turn drives the reciprocating screw 304 to rotate. When the reciprocating screw 304 rotates, the screw sleeve 303 moves linearly along the reciprocating screw 304. The guide rod 305 ensures the stable sliding of the screw sleeve 303. The screw sleeve 303 drives the connecting rod 302 and the turning plate 301 to slide on the top of the drying table 101, turning the tea leaves periodically to ensure that the tea leaves are evenly exposed to air and dried.

[0043] This equipment, through its sliding air-blowing box 201 and multi-point distributed air-blowing pipes 202, achieves a more uniform airflow distribution, avoiding the problem of localized drying being too fast or too slow. The position of the air-blowing box 201 is adjustable to accommodate different types of tea and varying drying volumes, improving the system's adaptability and flexibility. Combined with the turning mechanism 300, it enables automatic turning of the tea leaves, reducing manual intervention and improving work efficiency.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
