Description

Technical Field

[0001] This invention relates to the field of agricultural product processing equipment, specifically to an intelligent detection device for the dryness of tea leaves during the processing of Wuniuzao tea. Background Technology

[0002] Wuniuzao is a famous early-maturing green tea variety in my country. It is highly favored by the market due to its early market availability, delicate aroma, and fresh taste. Its processing quality directly affects the commercial value and drinking experience of the tea. Drying is a crucial step in the processing of Wuniuzao, and the degree of dryness is the core indicator for measuring the quality of the drying process.

[0003] In existing technologies, such as the Dayu Weighing Instrument Moisture Analyzer, a device consists of a heating ring halogen lamp, a weighing sensor, and a display screen. During testing, the initial weight of the sample is first measured using the moisture analyzer. Then, the sample is heated using the halogen lamp to evaporate the moisture. During the heating process, the weighing device continuously records the weight change of the sample. After evaporation is complete, the moisture content, or dryness, of the sample is calculated based on the initial and final weights.

[0004] In practical use, the aforementioned measuring instrument uses offline sampling to determine the dryness of tea leaves, taking only a small number of samples from each processing batch for testing. This makes it impossible to check the dryness of all tea leaves, and the test results only represent the condition of a local sample. Because the dryness of Wuniuzao tea leaves is affected by factors such as hot air distribution and the thickness of the spreading material during the drying process, the dryness of tea leaves in different locations within the same batch may vary. Sampling testing cannot cover all tea leaves, easily leading to missed detection of substandard products and affecting the uniformity of product quality. In summary, how to solve the problem of low product quality caused by missed detection of substandard products has become an urgent problem to be solved in this field. Therefore, it is necessary to propose an intelligent detection device for the dryness of Wuniuzao tea leaves during processing. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an intelligent detection device for the dryness of tea leaves during the processing of Wuniuzao tea. This device is used to conduct online dryness qualification testing on all tea leaves on the processing production line. It can obtain the dryness data of each batch of tea leaves without sampling, and performs secondary testing through a mixing device to ensure the accuracy of the test data, thereby guaranteeing the stability and consistency of the quality of the finished tea products.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An intelligent detection device for the dryness of tea leaves during the processing of Wuniuzao tea includes a first detection area and a second detection area. The first detection area is located to one side of the second detection area, and the horizontal height of the first detection area is higher than that of the second detection area. It also includes a controller, and both the first and second detection areas are equipped with conveying components for conveying tea leaves.

[0007] The conveying assembly includes symmetrically arranged baffles and several supports. The tops of the supports are fixedly connected to the bottoms of the baffles. A conveyor belt is installed between adjacent baffles. A controller is used to control the operation of the conveyor belt.

[0008] A leveling box is installed above the conveyor belt. The bottom of the leveling box is fixedly connected to the top of the adjacent baffle. A straight groove is opened at the bottom of the leveling box. The leveling box is equipped with a leveling component for spreading the tea leaves.

[0009] Each conveyor belt is equipped with a connecting plate, and the bottom of the connecting plate is fixedly connected to the top of the adjacent baffle. Each connecting plate is equipped with a detection component for detecting the drying status of the tea leaves.

[0010] Each conveyor belt is equipped with auxiliary components for secondary leveling of the tea leaves.

[0011] A mixing chamber is provided on one side of the first detection area. The top of the mixing chamber is fixedly connected to the bottom of the baffle in the first detection area. A discharge port is opened at the bottom of the mixing chamber. The bottom of the mixing chamber is fixedly connected to the top of the baffle in the second detection area. A flexible hose is connected to the side of the mixing chamber near the baffle in the first detection area.

[0012] The first testing area also has a pressure component in the leveling box used to mix the tea leaves in the mixing box.

[0013] The technical principle of the above solution is as follows: A conveyor assembly continuously transports tea leaves along the production line. A baffle forms a detection channel to prevent tea leaves from falling from the sides. With the help of a leveling assembly and auxiliary components, the tea leaves are spread to a thickness of less than 3cm. The detection assembly then collects data on the specific condition of the tea leaves in each area, achieving comprehensive detection rather than sampling and inference. After the first detection, a mixing assembly, under the action of a pneumatic component, mixes the tea leaves thoroughly before they fall onto the conveyor belt in the second detection area for a second detection. This reduces the random errors that may occur in a single detection while ensuring the accuracy of the data.

[0014] The above approach has the following beneficial effects:

[0015] 1. This invention uses a flattening component and an auxiliary component designed on the top of the baffle to flatten the tea leaves. Combined with the detection component, the overall condition of the tea leaves can be detected in real time. This reduces the impact on detection accuracy caused by uneven flattening height of the tea leaves during the detection process, thus reducing the phenomenon of missed detection of unqualified products. At the same time, it also reduces the pass rate of low-quality tea leaves, thereby improving the final quality of the tea leaves.

[0016] 2. This invention improves the accuracy of the test results and avoids random errors by repeatedly testing tea leaves in a first detection area and a second detection area, combined with the mixing effect of the mixing component.

[0017] 3. This invention uses online comprehensive dryness detection, and the detection results can be directly fed back to the production control system, providing data support for the dynamic adjustment of drying process parameters. This helps to reduce manual intervention, optimize the production process, improve the automation and intelligence level of Wuniuzao processing, reduce the rework rate caused by unqualified dryness, and indirectly improve production efficiency and yield.

[0018] Furthermore, the leveling component includes a limiting block fixedly connected to the bottom wall of the leveling box, a fixed plate fixedly connected to the limiting block, a groove opened on the fixed plate, and a moving plate slidingly engaged in the groove.

[0019] A support block is fixedly connected to the bottom of the motion plate. A through hole is opened on the support block, and a rotating rod is rotatably fitted inside the through hole. One end of the rotating rod extends through a straight groove to the outside of the push-flat box and is fixedly connected to a push plate. The other end of the rotating rod extends through the through hole to the top of the support block and is fixedly connected to a connecting rod. A movable rod is hinged to the end of the connecting rod away from the rotating rod. A block is hinged to the end of the movable rod away from the connecting rod. One side of the block is fixedly connected to a limiting block. The push-flat box is equipped with a power component for driving the movement of the push plate.

[0020] Beneficial effects: The groove design provides a limit to the movement trajectory of the moving plate, ensuring that it maintains a straight line during movement, reducing deviation and improving the stability of the device. Simultaneously, the hinged connection between the connecting rod, movable rod, and block, along with the sliding of the rotating rod in the straight groove, allows the push plate to move flexibly in multiple directions, improving the efficiency of tea leaf spreading.

[0021] Furthermore, the power assembly includes a fixed block fixedly connected to the top of the limiting block, a drive electric actuator fixedly connected to the fixed block, a controller for controlling the extension and retraction of the output shaft of the drive electric actuator, an extension block fixedly connected to the motion plate, and the output shaft of the drive electric actuator fixedly connected to the extension block.

[0022] Beneficial effects: The electric actuator, as a power source, can provide stable and reliable thrust. Through the extension block, it drives the moving plate to reciprocate, which can achieve efficient leveling of tea leaves.

[0023] Furthermore, the auxiliary components include a leveling bar located above the conveyor belt, the bottom of which is fixedly connected to the top of its adjacent baffle, and the leveling bar is located on one side of the leveling box.

[0024] Beneficial effects: The design of the leveling bar allows the tea leaves to be trimmed and flattened a second time, thereby further reducing the thickness deviation of the tea leaves and making the surface of the tea leaves smoother. This provides a more uniform testing environment for subsequent real-time testing of the tea leaves and improves the accuracy and consistency of the test data.

[0025] Furthermore, the pneumatic assembly includes a piston cylinder fixedly connected to the inner wall of the leveling box, a piston plate slidably fitted to the inner wall of the piston cylinder, a piston rod fixedly connected to one side of the piston plate, and the end of the piston rod away from the piston plate fixedly connected to the moving plate; the piston cylinder has an air inlet and an air outlet, both of which are connected to a one-way valve. The one-way valve at the air inlet allows flow from the outside of the piston cylinder to the inside of the piston cylinder, and the one-way valve at the air outlet allows flow from the inside of the piston cylinder to the outside of the piston cylinder; the leveling box side wall of the first detection area has a square opening, and the end of the hose away from the mixing box is connected to the inside of the piston cylinder through the square opening and the air outlet.

[0026] Beneficial effects: The piston rod drives the piston plate to reciprocate inside the piston cylinder. The one-way valve enables the intake and exhaust of gas. The exhaust gas enters the mixing chamber through the hose, providing airflow disturbance for the tea leaves inside the mixing chamber, assisting in the mixing of the tea leaves. While enhancing the mixing effect, it also lays the foundation for the accuracy of secondary testing.

[0027] Furthermore, a receiving box is installed at the end of the conveyor belt in the second detection area.

[0028] Beneficial effects: By setting up receiving boxes to collect tea leaves that have undergone two tests, waste and pollution caused by tea leaf spillage are reduced, and subsequent processing or handling procedures are facilitated.

[0029] Furthermore, the mixing box is funnel-shaped.

[0030] Beneficial effects: The funnel-shaped mixing box uses gravity to allow the tea leaves to naturally converge downwards, which is conducive to thorough mixing of the tea leaves during the falling process. At the same time, it makes it easier for the tea leaves to fall accurately from the discharge port onto the conveyor belt in the second detection area, reducing tea leaf residue.

[0031] Furthermore, the rotating rod has a nested structure, which includes an upper rotating rod and a lower rotating rod. The upper rotating rod is hollow, and the lower rotating rod slides against the inner wall of the upper rotating rod. An adjusting electric actuator is fixedly connected to the inner top wall of the upper rotating rod. The output shaft of the adjusting electric actuator is fixedly connected to the lower rotating rod, and the controller is used to control the extension and retraction of the output shaft of the adjusting electric actuator.

[0032] Beneficial effects: The nested design of the rotating rod allows for flexible adjustment of the height of the push plate, thereby precisely controlling the thickness of the tea leaves and adapting to the requirements of different processing stages for tea thickness. This improves the versatility and adaptability of the device, enabling it to provide the appropriate tea thickness for the testing process under different production conditions, thus ensuring the stability of the testing results.

[0033] Furthermore, an anti-slip layer is fixedly connected to the bottom of the receiving box.

[0034] Beneficial effects: The anti-slip layer increases the friction between the receiving box and the ground, preventing the receiving box from sliding due to impact or vibration during tea collection.

[0035] Furthermore, the detection component includes an infrared sensor probe and a microwave moisture sensor probe fixedly connected to the bottom of the connecting plate. The controller is electrically connected to a cloud processor and a worker terminal. The controller is used to receive the infrared signal sent by the infrared sensor probe and the moisture signal sent by the microwave moisture sensor probe, send the infrared signal and the moisture signal to the cloud processor for analysis, obtain the drying result, send the drying result to the controller, and the controller sends the drying result to the worker terminal.

[0036] Beneficial effects: By using an infrared sensor probe to detect the surface temperature distribution and radiation characteristics of tea leaves, and combining this with the microwave moisture sensor probe's ability to penetrate the tea leaf layer and detect the internal moisture content, it is possible to simultaneously detect the surface and internal dryness of tea leaves. This improves the accuracy and comprehensiveness of dryness assessment and reduces misjudgments caused by environmental interference or detection blind spots of a single sensor.

[0037] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0045] The following detailed description illustrates the specific implementation method:

[0046] Example 1:

[0047] As attached Figure 1 As shown: A smart detection device for the dryness of tea leaves during the processing of Wuniuzao tea includes a first detection area and a second detection area. The first detection area is located on one side of the second detection area, and the horizontal height of the first detection area is higher than that of the second detection area.

[0048] It also includes a controller, and both the first and second detection zones are equipped with conveying components for conveying tea leaves.

[0049] The conveying assembly includes symmetrically arranged baffles 1 and several supports 3. The top of each support 3 is welded to the bottom of the baffle 1. A conveyor belt 2 is installed between adjacent baffles 1. A controller is used to control the operation of the conveyor belt 2.

[0050] A flattening box 4 is provided above the conveyor belt 2. The bottom of the flattening box 4 is welded to the top of the adjacent baffle 1. A straight groove is opened at the bottom of the flattening box 4.

[0051] Specifically, the staff places the dried tea leaves on conveyor belt 2 in the first inspection area, and then controls all conveyor belts 2 to start via the controller, transporting the tea leaves towards the flattening box 4. During this process, because the baffles 1 are symmetrically arranged on both sides of the conveyor belt 2, the tea leaves are blocked by the baffles 1 during transportation, reducing the possibility of the tea leaves falling and thus improving the stability of the device when transporting tea leaves.

[0052] like Figure 3 As shown, the leveling box 4 is equipped with a leveling component for spreading the tea leaves. The leveling component includes a limiting block 10 welded to the bottom wall of the leveling box 4, a fixing plate 8 integrally formed on the limiting block 10, a sliding groove 9 on the fixing plate 8, and a moving plate 7 slidingly fitted in the sliding groove 9.

[0053] The bottom of the motion plate 7 is integrally formed with a support block 13. The support block 13 has a through hole, and a rotating rod 15 is rotatably fitted inside the through hole. One end of the rotating rod 15 extends through a straight groove to the outside of the push-flat box 4 and is welded with a push plate 16. The other end of the rotating rod 15 extends through the through hole to the top of the support block 13 and is welded with a connecting rod 14. The end of the connecting rod 14 away from the rotating rod 15 is hinged with a movable rod 12. The end of the movable rod 12 away from the connecting rod 14 is hinged with a block 11. One side of the block 11 is integrally formed with the limiting block 10.

[0054] The pusher box 4 is equipped with a power assembly for driving the pusher plate 16. The power assembly includes a fixing block 6 integrally formed on the top of the limiting block 10, a drive electric actuator 5 is bolted to the fixing block 6, a controller is used to control the extension and retraction of the output shaft of the drive electric actuator 5, an extension block is welded to the motion plate 7, and the output shaft of the drive electric actuator 5 is bolted to the extension block.

[0055] Specifically, the staff controls the operation of the drive electric actuator 5, causing its output shaft to reciprocate. At this time, the output shaft of the drive electric actuator 5 can drive the extension block that is bolted to it to reciprocate laterally, and then the extension block drives the motion plate 7 welded to it to reciprocate laterally.

[0056] During the lateral reciprocating motion, the motion plate 7 slides laterally within the slide groove 9. At this time, the slide groove 9 limits the movement path of the motion plate 7, reducing the possibility of its deviation, thereby improving the movement stability of the motion plate 7.

[0057] During its movement, the moving plate 7 also drives the integrally formed support block 13 to reciprocate laterally, which in turn drives the rotating rod 15 to reciprocate laterally. Since the two ends of the rotating rod 15 are welded to the push plate 16 and the connecting rod 14 respectively, it can drive the push plate 16 and the connecting rod 14 to reciprocate laterally. Furthermore, since the connecting rod 14 is hinged to the movable rod 12, and the movable rod 12 is hinged to the block 11, and the block 11 is integrally formed with the limiting block 10, when the connecting rod 14 moves horizontally, it will be limited by the movable rod 12 and swing, which in turn causes the rotating rod 15 to rotate. The rotating rod 15 then drives the push plate 16 to rotate, and the lateral reciprocating motion and rotation of the push plate 16 initially flattens the tea leaves.

[0058] like Figure 2 As shown, each conveyor belt 2 is equipped with an auxiliary component for secondary leveling of the tea leaves. The auxiliary component includes a leveling bar 26 located above the conveyor belt 2. The bottom of the leveling bar 26 is welded to the top of the adjacent baffle 1, and the leveling bar 26 is located on one side of the leveling box 4.

[0059] Specifically, after the initial leveling of the tea leaves is completed, the conveyor belt 2 will continue to move the tea leaves towards the leveling bar 26. Since the leveling bar 26 is located above the conveyor belt 2 and is welded to the top of the baffle 1, when the height of the tea leaves is higher than the leveling bar 26, they can be leveled a second time by the leveling bar 26 during the movement, further improving the leveling quality of the tea leaves.

[0060] Each conveyor belt 2 is equipped with a connecting plate 25 above it. The bottom of the connecting plate 25 is welded to the top of the adjacent baffle 1. Each connecting plate 25 is equipped with a detection component for detecting the drying status of tea leaves.

[0061] like Figure 6 As shown, the detection assembly includes an infrared sensor probe 23 and a microwave moisture sensor probe 24, which are fixedly connected to the bottom of the connecting plate 25 with screws. The controller is electrically connected to a cloud processor and a worker terminal. The controller is used to receive the infrared signal sent by the infrared sensor probe 23 and the moisture signal sent by the microwave moisture sensor probe 24, send the infrared signal and the moisture signal to the cloud processor for analysis, obtain the drying result, send the drying result to the controller, and the controller sends the drying result to the worker terminal.

[0062] Specifically, after the tea leaves are leveled, conveyor belt 2 continues to move the tea leaves towards connecting plate 25. When the tea leaves reach below connecting plate 25, infrared sensor probe 23 and microwave moisture sensor probe 24 located below connecting plate 25 will detect the drying status of the tea leaves in real time, obtaining infrared and moisture signals respectively. The controller sends the infrared and moisture signals to the cloud processor for analysis to obtain the drying result of the tea leaves. At this time, the cloud processor sends the drying result back to the controller, and the controller then sends the drying result to the operator's terminal for viewing.

[0063] like Figure 1 , Figure 2 and Figure 4 As shown, a funnel-shaped mixing box 28 is provided on one side of the first detection area. The top of the mixing box 28 is welded to the bottom of the baffle 1 in the first detection area. The bottom of the mixing box 28 has a discharge port. The bottom of the mixing box 28 is welded to the top of the baffle 1 in the second detection area. A flexible hose 18 is connected to the side of the mixing box 28 near the baffle 1 in the first detection area.

[0064] The first testing area's leveling box 4 is also equipped with a pneumatic component for mixing the tea leaves in the mixing box 28.

[0065] like Figure 5As shown, the pneumatic assembly includes a piston cylinder 17 welded to the inner wall of the leveling box 4. A piston plate 22 is slidably fitted onto the inner wall of the piston cylinder 17. A piston rod 21 is welded to one side of the piston plate 22, and the end of the piston rod 21 away from the piston plate 22 is welded to the moving plate 7. The piston cylinder 17 has an air inlet 19 and an air outlet 20. Both the air inlet 19 and the air outlet 20 are connected to one-way valves. The one-way valve at the air inlet 19 allows flow from the outside of the piston cylinder 17 to the inside of the piston cylinder 17, while the one-way valve at the air outlet 20 allows flow from the inside of the piston cylinder 17 to the outside of the piston cylinder 17. A square opening 29 is opened on the side wall of the leveling box 4 in the first detection area. The end of the hose 18 away from the mixing box 28 is connected to the inside of the piston cylinder 17 through the square opening 29 and the air outlet 20. A receiving box 27 is provided at the end of the conveyor belt 2 in the second detection area.

[0066] Specifically, such as Figure 1 and Figure 2 As shown, after the tea leaves are tested in the first testing area, the top and bottom of the mixing box 28 are welded to the bottom of the baffle 1 in the first testing area and the top of the baffle 1 in the second testing area, respectively. Therefore, the conveyor belt 2 in the first testing area can transport the tea leaves into the mixing box 28. During this process, the moving plate 7 will reciprocate laterally, and the two ends of the piston rod 21 are welded to the moving plate 7 and the piston plate 22, respectively. Therefore, the moving plate 7 can sequentially drive the piston rod 21 and the piston plate 22 to reciprocate laterally. At this time, the piston plate 22 will disturb the gas in the piston cylinder 17. Figure 5 As shown, when the piston plate 22 moves to the left, the volume on its right side increases, generating negative pressure. This pressure draws gas from outside the piston cylinder 17 into the piston cylinder 17 through the one-way valve at the air inlet 19. When the piston plate 22 moves to the right, it compresses the gas on its right side, causing it to be discharged through the one-way valve at the air outlet 20. Since the two ends of the hose 18 are connected to the piston cylinder 17 and the mixing box 28 respectively, when the gas is discharged from the air outlet 20 and enters the hose 18, it can be released into the mixing box 28 under the guidance of the hose 18. As the tea leaves are continuously transported into the mixing box 28, they are disturbed by the airflow, allowing the tea leaves in different areas to be mixed evenly and then fall onto the conveyor belt 2 in the second detection area.

[0067] After the tea leaves fall onto the second conveyor belt 2, the second conveyor belt 2 will move them towards the receiving box 27. During this process, the tea leaves will be flattened and inspected again in the second inspection area, and the drying results of the tea leaves in the second inspection area will also be sent to the staff terminal simultaneously. The flattening and inspection method of the tea leaves in the second inspection area is the same as that in the first inspection area, and will not be described in detail here.

[0068] After the tea leaves have been tested in the second testing area, the conveyor belt 2 in the second testing area will transport the tea leaves to the receiving box 27 to complete the tea leaf testing operation.

[0069] This invention sets up a first detection zone and a second detection zone on the production line, which work together to perform two tests on all batches of tea. This enables online, comprehensive, and accurate detection of the dryness of Wuniuzao tea during processing, ensuring accurate and reliable test results and improving the product quality of Wuniuzao tea.

[0070] Example 2:

[0071] The difference from Embodiment 1 is that the rotating rod 15 is a nested structure, which includes an upper rotating rod and a lower rotating rod. The upper rotating rod is hollow, and the lower rotating rod slides with the inner side wall of the upper rotating rod. An adjusting electric actuator is fixedly connected to the inner top wall of the upper rotating rod with screws. The output shaft of the adjusting electric actuator is fixedly connected to the lower rotating rod with screws. The controller is used to control the extension and retraction of the output shaft of the adjusting electric actuator.

[0072] The specific implementation process is as follows: The staff controls the extension and retraction length of the output shaft of the electric push rod through the controller, which can adjust the extension and retraction length of the lower rotating rod. In turn, the lower extension rod drives the push plate 16 to move up and down, thereby adjusting the height of the push plate 16 and changing the distance between the push plate 16 and the conveyor belt 2. This allows for precise control of the tea leaf spreading thickness, adapting to the requirements of different processing stages for tea leaf thickness, ensuring that the appropriate tea leaf thickness can be provided for tea leaf dryness detection under different production conditions, and guaranteeing the stability of the detection results.

[0073] Example 3:

[0074] The difference from Embodiment 2 is that the bottom of the receiving box 27 is glued and fixed with an anti-slip layer.

[0075] The specific implementation process is as follows: By attaching a fixed anti-slip layer to the bottom of the receiving box 27, the receiving box 27 is prevented from sliding when it receives the impact of tea leaves, which would cause the falling tea leaves to spill and cause pollution.

[0076] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
