Description

Technical Field

[0001] This utility model belongs to the field of Chinese medicinal material processing, specifically a Chinese medicinal material drying and sun-drying device. Background Technology

[0002] In the processing of traditional Chinese medicinal materials, sun-drying and drying are crucial steps in ensuring the efficacy of the herbs and extending their shelf life. As core processing equipment, the traditional Chinese medicinal material sun-drying and drying device removes surface moisture from the herbs through natural sun-drying, followed by drying to further reduce the moisture content and achieve proper drying and shaping. This device is widely used in traditional Chinese medicinal material planting bases, processing plants, and other settings. It connects the initial processing steps after harvesting, providing a fundamental guarantee for subsequent processing, storage, and sales, and is an important tool for improving the efficiency and quality of traditional Chinese medicinal material processing.

[0003] Currently, most existing Chinese medicinal herb drying equipment cannot achieve integrated drying and drying operations. It requires manual handling of the herbs between the drying area and the drying equipment, which not only increases labor costs but also makes the herbs susceptible to moisture or damage due to environmental changes during handling. Utility Model Content

[0004] The purpose of this utility model is to provide a drying device for Chinese medicinal materials, so as to solve the problem that the existing technology is difficult to achieve integrated drying and drying operations, which not only increases labor costs, but also makes the medicinal materials susceptible to moisture or damage due to environmental changes during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for Chinese medicinal herbs, comprising a shell, a support frame, and a heat pump drying mechanism; the heat pump drying mechanism is fixedly connected to one side of the shell, a controller is fixedly connected to the surface of the heat pump drying mechanism, an electric guide rail is movably installed at the bottom inside the shell, a support frame is installed on the top of the electric guide rail, a drying board is movably installed on the inner side of the support frame, and a protective door is movably installed on the surface of the shell; a photosensitive sensor is fixedly connected to the top of the shell, and a temperature and humidity sensor is fixedly connected to the top of the shell on one side of the photosensitive sensor.

[0006] Preferably, one end of the protective door is fixedly connected to a slide rail, and the slide rail is arranged parallel to the electric guide rail.

[0007] Preferably, both sides of the drying board are fixedly connected to limit blocks, and the limit blocks are fitted into the support frame.

[0008] Preferably, there are four drying boards, which are arranged alternately in front of and behind each other.

[0009] Preferably, a connecting block is fixedly connected to one side of the protective door, and a handle is fixedly connected to the inner side of the connecting block.

[0010] Preferably, the housing has an internal cavity that is adapted to the dimensions of the support frame and the drying board.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model, by setting an electric guide rail at the bottom of the shell, in conjunction with a movable support frame and a protective door connected by a spring hinge, enables the support frame to automatically move the drying board into and out of the shell, eliminating the need for manual pushing and pulling of the protective door and handling of Chinese medicinal materials. At the same time, the heat pump drying mechanism operates automatically according to preset parameters, reducing manual intervention throughout the process and significantly improving the automation and efficiency of drying Chinese medicinal materials. Furthermore, the shell cavity is sized to match the support frame and drying board, forming a relatively sealed space during drying, reducing heat loss, ensuring a stable drying environment, and improving drying quality.

[0013] 2. This utility model incorporates a temperature and humidity sensor and a photosensitive sensor on the top of the housing. The temperature and humidity sensor uses a sensitive element to convert the ambient temperature and humidity into electrical signals and transmit them to the controller. The photosensitive sensor, based on the photoelectric effect, converts light intensity into electrical signals and feeds them back to the controller. This allows for real-time monitoring of the drying environment parameters. When the parameters are unsuitable, the controller automatically controls the electric guide rail to pull back the support frame, closes the protective door, and starts the heat pump drying mechanism. This prevents the medicinal herbs from becoming damp or insufficiently dried due to environmental factors, thus improving the intelligence and reliability of the drying process.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As attached Figure 1 To be continued Figure 4 As shown:

[0023] Example 1: This utility model provides a drying device for Chinese medicinal materials, including a shell 1, a support frame 2 and a heat pump drying mechanism 6; the heat pump drying mechanism 6 is fixedly connected to one side of the shell 1, the controller 7 is fixedly connected to the surface of the heat pump drying mechanism 6, an electric guide rail 10 is movably installed at the bottom inside the shell 1, the support frame 2 is installed on the top of the electric guide rail 10, a drying board 3 is movably installed on the inner side of the support frame 2, and a protective door 4 is movably installed on the surface of the shell 1.

[0024] The staff first evenly spread the Chinese medicinal herbs to be processed on the drying board 3 inside the support frame 2. Using the controller 7 on the surface of the heat pump drying mechanism 6 on one side of the housing 1, the drying time and target parameters for the herbs are preset. When the device starts and enters the drying stage, the controller 7 sends a command to the electric guide rail 10. The electric guide rail 10 drives the top support frame 2 to move along the bottom track inside the housing 1. During the movement, the support frame 2 pushes the protective door 4 on the surface of the housing 1 open until the support frame 2 is completely moved to the top position of the protective door 4, allowing the drying board 3 and the herbs above it to fully extend outside the device and fully contact the external natural environment for drying. When the set drying time is met... After a certain time, the controller 7 immediately controls the electric guide rail 10 to pull the support frame 2 back into the housing 1. At the same time, the protective door 4, which is connected to the housing 1 by a spring hinge, automatically springs back and closes under the action of the spring force. Then, the controller 7 starts the heat pump drying mechanism 6. Its drying principle is as follows: the heat pump system absorbs heat from the external environment through the evaporator, and after being compressed by the compressor, the low-temperature and low-pressure refrigerant vapor is converted into high-temperature and high-pressure vapor. Then, the heat is released into the housing 1 through the condenser. At the same time, the fan evenly delivers hot air into the housing 1 to heat and dry the Chinese medicinal materials, completing the automatic drying and drying integrated process of Chinese medicinal materials, reducing manual intervention throughout the process and improving work efficiency.

[0025] In one embodiment of this utility model, a slide rail 5 is fixedly connected to one end of the protective door 4, and the slide rail 5 is arranged parallel to the electric guide rail 10.

[0026] Since the slide rail 5 is set parallel to the electric guide rail 10 at the bottom of the housing 1, the opening and closing direction of the protective door 4 is consistent with the moving direction of the support frame 2 during the movement of the support frame 2 and the drying board 3 driven by the electric guide rail 10, so as to avoid the interference caused by the intersection of the two movement trajectories and ensure that the support frame 2 can smoothly enter and exit the housing 1.

[0027] In one embodiment of this utility model, both sides of the drying board 3 are fixedly connected with limiting blocks 301, and the limiting blocks 301 are fitted into the support frame 2.

[0028] The limiting block 301 is made of anti-slip silicone. Through the structural cooperation between the limiting block 301 and the support frame 2, the installation position of the drying board 3 is accurately positioned to prevent the drying board 3 from shifting left or right on the support frame 2. During the operation of the device, whether the electric guide rail 10 moves the support frame 2 or the heat pump drying mechanism 6 generates airflow, the limiting block 301 can restrict the displacement of the drying board 3.

[0029] In one embodiment of this utility model, four drying boards 3 are provided, and the four drying boards 3 are arranged alternately in front and behind.

[0030] Four alternating drying boards 3 are movably installed on the inner side of the support frame 2. This arrangement maximizes the use of vertical space for placing Chinese medicinal materials within the limited cavity space of the shell 1, while also creating a reasonable gap between adjacent drying boards 3. When the heat pump drying mechanism 6 delivers hot air into the shell 1 for drying, the hot air can circulate evenly through the gaps between the drying boards 3, avoiding the accumulation of Chinese medicinal materials that could lead to uneven heating in certain areas.

[0031] In one embodiment of the present invention, a connecting block 402 is fixedly connected to one side of the protective door 4, and a handle 401 is fixedly connected to the inner side of the connecting block 402.

[0032] When the protective door 4 needs to be operated, the force exerted by the operator's hand is transmitted to the connecting block 402 through the handle 401, and then the connecting block 402 drives the protective door 4 to move. The connecting block 402, as the connecting carrier between the handle 401 and the protective door 4, can evenly distribute the force on the handle 401 onto the protective door 4, avoiding localized damage to the protective door 4 due to concentrated force. At the same time, the handle 401 provides the operator with a convenient point of force application, reducing the contact area between the hand and the protective door 4 compared to directly pushing its surface, thus reducing the difficulty of operation.

[0033] In one embodiment of this utility model, the interior of the housing 1 is provided with a cavity, and the cavity is adapted to the size of the support frame 2 and the drying board 3.

[0034] The internal cavity of the housing 1 is sized to match the support frame 2 and the drying plate 3. When the support frame 2 moves the drying plate 3 into the housing 1 under the action of the electric guide rail 10, the support frame 2 and the drying plate 3 can be completely accommodated in the cavity, making the housing 1 a relatively sealed space. During the drying operation of the heat pump drying mechanism 6, the sealed cavity can reduce heat loss and ensure a stable temperature and humidity environment inside the housing 1.

[0035] Working Principle: The operator first spreads the medicinal herbs to be processed evenly on the drying board 3 inside the support frame 2. Then, the operator operates the controller 7 on the surface of the heat pump drying mechanism 6 to preset the required drying time and parameters. After the device starts, if the drying stage begins first, the controller 7 sends a running command to the electric guide rail 10. The electric guide rail 10 then moves the top support frame 2 along the bottom track inside the housing 1. During the movement, the support frame 2 pushes the protective door 4 on the surface of the housing 1 to open it until the support frame 2 is completely moved to the top of the protective door 4. At this point, the drying board 3 and the medicinal herbs above it are fully extended outside the device, allowing them to fully contact the external environment for drying. When the drying time reaches the preset value, the controller 7 immediately controls the electric guide rail 10 to reverse, pulling the support frame 2 back into the housing 1. Simultaneously, the protective door 4, connected to the housing 1 by a spring hinge, automatically springs back and closes under the action of the spring force. Next, the controller 7 starts the heat pump drying mechanism 6. The drying process is as follows: the evaporator of the heat pump system first absorbs heat from the external environment, and then the refrigerant is compressed by the compressor to convert the low-temperature and low-pressure refrigerant vapor into high-temperature and high-pressure vapor. Subsequently, the high-temperature and high-pressure vapor enters the condenser and releases heat into the interior of the shell 1. With the help of the fan, the heat is evenly transported to the inner cavity of the shell 1 to heat and dry the Chinese medicinal materials. Finally, the automatic drying and sun-drying of Chinese medicinal materials is completed. The whole process does not require frequent manual operation and effectively improves work efficiency.

[0036] Example 2: This example is basically the same as the previous example, except that a photosensitive sensor 9 is fixedly connected to the top of the housing 1, and a temperature and humidity sensor 8 is fixedly connected to the top of the housing 1 on the side of the photosensitive sensor 9.

[0037] Workers place the Chinese medicinal herbs on drying racks 3 on different support frames 2. The controller 7 sets the drying time, heat treatment time, and corresponding temperature, humidity, and light adaptation thresholds for each batch of herbs. After the device is started, the support frame 2 containing the herbs, driven by the electric guide rail 10, pushes the protective door 4 open and moves to the top of the protective door 4 for drying. At this time, the temperature and humidity sensor 8 uses its sensitive element to convert the ambient temperature and humidity signal into an electrical signal, which is processed by the internal circuit and transmitted to the controller 7, enabling real-time acquisition of temperature and humidity data. The photosensitive sensor 9, based on the photoelectric effect, generates a photocurrent when light shines on its internal photosensitive element. The magnitude of the photocurrent changes with the light intensity. After signal processing, the light intensity data is fed back to the controller 7. When the temperature, humidity, or light is detected to be unsuitable for drying, the controller 7 controls the electric guide rail 10 to pull it back into the housing 1, the protective door 4 automatically closes, and the heat pump drying mechanism 6 starts to dry the herbs, preventing them from becoming damp or insufficiently dried due to environmental factors.

[0038] Working principle: During the drying process, the temperature and humidity sensor 8 on the top of the housing 1 works in real time. Its internal temperature and humidity sensitive element converts the ambient temperature and humidity signal into an electrical signal, which is then processed by the internal circuit and transmitted to the controller 7 to realize the real-time acquisition of ambient temperature and humidity data. At the same time, the photosensitive sensor 9 is based on the photoelectric effect principle. When external light shines on its internal photosensitive element, it generates a photocurrent. The intensity of the photocurrent changes with the intensity of the light. After signal processing, the light intensity data is fed back to the controller 7. If the temperature and humidity sensor 8 or the photosensitive sensor 9 detects that the ambient temperature, humidity, or light exceeds the preset adaptation threshold, the controller 7 will immediately control the electric guide rail 10 to pull the support frame 2 back into the housing 1, the protective door 4 will automatically close, and then the heat pump drying mechanism 6 will be started to dry the batch of Chinese medicinal materials to prevent the Chinese medicinal materials from getting damp or not drying properly due to unsuitable environment.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
