Abstract
Description
Technical Field
[0001] This application relates to the field of traditional Chinese medicine drying technology, specifically to a drying device for processing traditional Chinese medicine with uniform heating. Background Technology
[0002] Drying is a crucial step in the processing of traditional Chinese medicine (TCM), directly impacting its quality and shelf life. However, existing TCM drying equipment suffers from several problems. Firstly, many traditional drying systems fail to effectively address the adhesion and accumulation of herbs during drying, leading to insufficient contact between the herbs and hot air, uneven drying, and compromised quality. Secondly, uneven stress during the rotation of the drying chamber during operation can cause instability, reducing equipment lifespan and potentially causing safety accidents. Furthermore, some drying systems are cumbersome to operate during loading and unloading of herbs, increasing the workload and time costs for operators. In addition, some drying equipment has low thermal efficiency, with rapid hot air exhaust resulting in significant heat waste, failing to meet energy conservation and environmental protection requirements.
[0003] Therefore, it is of great significance to develop a drying device for Chinese medicine processing that can achieve uniform drying of Chinese medicine, stable operation, convenient operation, and high efficiency in heat energy utilization. Summary of the Invention
[0004] In response to the above-mentioned technical problems, this application solves the problems in the prior art where the Chinese medicines stick together or pile up, resulting in uneven drying of some Chinese medicines and poor equipment stability when the drying box rotates.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a drying device for uniform heating in traditional Chinese medicine processing, comprising a support frame, an upper driving rod and a lower connecting rod rotatably mounted on the support frame, a drying box rotatably mounted on the upper driving rod, an upper connecting cover and a lower connecting cover fixedly mounted on the drying box, the lower connecting cover being rotatably connected to the lower connecting rod, the lower connecting rod being a hollow structure, the drying box always being tilted, a frame rotatably mounted on the drying box, a rotating shaft fixedly connected to the frame, a sliding rod rotatably mounted on the rotating shaft, a sliding groove provided on the sliding rod, and an assisting component slidably mounted on the sliding groove.
[0006] Preferably, the assisting component includes an assisting rod, a spring, and an assisting ball. The assisting rod is slidably mounted on the support frame, the spring is sleeved on the assisting rod, the assisting rod is fixedly connected to the assisting ball, and the two ends of the spring are fixedly connected to the support frame and the assisting ball, respectively.
[0007] Preferably, the assist ball is slidably disposed on the groove of the slide rod, the slide rod and the assist ball are configured to cooperate, and the slide rod forms a semi-enclosed state on the assist ball to restrict the assist ball from detaching from the direction perpendicular to the slide rod, while allowing the assist ball to slide along the extension direction of the slide rod.
[0008] Preferably, the drying oven is equipped with a removable door panel.
[0009] Preferably, a hot air blower is installed on the support frame, and the air nozzle of the hot air blower is connected to the lower connecting rod.
[0010] Preferably, the upper connecting cover has multiple narrow ventilation slots near the upper drive rod.
[0011] Preferably, a guide plate is provided on the inner wall of the lower connecting cover, and multiple ventilation slots are provided where the guide plate contacts the lower connecting cover.
[0012] Preferably, the drying oven is fixedly installed with multiple filters for partitioning.
[0013] The technical solution provided in this application has the following advantages compared with the prior art:
[0014] 1. The drying oven of this application tilts and rotates around its axis under the drive of a motor, which makes the Chinese medicine inside the oven shake fully, separates the Chinese medicines that are stuck together, and ensures that the Chinese medicines can come into full contact with the hot air, thereby achieving uniform drying and improving the drying effect.
[0015] 2. The guide plate inside the lower connecting cover of this application guides the hot air to move upwards from all sides, increasing the contact between the hot air and the Chinese herbal medicine distributed against the wall in a tilted and swaying state, further improving the uniformity of drying. At the same time, the narrow ventilation slot of the upper connecting cover slows down the speed of hot air exhaust, prolongs the time that heat remains in the chamber, and enhances the drying effect.
[0016] 3. The drying oven of this application is equipped with multiple filters to separate the Chinese medicine, avoid the accumulation of large amounts of Chinese medicine, facilitate the smooth movement of hot air in the oven, and ensure that each part of the Chinese medicine can be fully heated and dried.
[0017] 4. The frame of this application is connected to the slide rod via a pivot. The slide rod slides on the vertical slide frame, and works with the assist component to support and limit the rotation of the drying chamber. The spring of the assist component provides tension or thrust according to the position of the slide rod, which not only assists the rotation of the drying chamber, but also prevents it from tilting excessively, effectively reducing the wear and tear caused by uneven force on the equipment and extending its service life.
[0018] 5. In this application, the upper drive rod and the lower connecting rod jointly support and drive the drying box to rotate, and the center of gravity of the drying box is located on the rotation axis. This structural design enables the drying box to maintain balance and stability during rotation, reducing shaking and wear during equipment operation.
[0019] 6. The drying oven of this application is equipped with a detachable door panel, which is connected by a locking block, making it convenient to put in and take out Chinese medicine, and ensuring the stability of the drying oven when it rotates, thus improving the ease of operation.
[0020] 7. The hot air generated by the hot air blower in this application is delivered to the drying chamber through the lower connecting rod. After making full contact with the Chinese medicine, it is slowly discharged from the narrow ventilation slot, which improves the utilization rate of heat and saves energy while ensuring the drying effect.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] like Figures 1 to 5As shown, a drying device for uniform heating in traditional Chinese medicine processing includes a support frame 101. An upper drive rod 112 and a lower connecting rod 114 are rotatably mounted on the support frame 101. A drying chamber 106 is rotatably mounted on the upper drive rod 112. An upper connecting cover 111 and a lower connecting cover 113 are fixedly mounted on the drying chamber 106. The lower connecting cover 113 is rotatably connected to the lower connecting rod 114. The lower connecting rod 114 has a hollow structure. The drying chamber 106 is always tilted. A frame 105 is rotatably mounted on the drying chamber 106. A rotating shaft 104 is fixedly connected to the frame 105. A sliding rod 103 is rotatably mounted on the rotating shaft 104. A sliding groove is provided on the sliding rod 103, and an assisting component is slidably mounted on the sliding groove.
[0030] Specifically, the Chinese herbs to be dried are placed into the drying chamber 106 through a pre-set opening, then the drying chamber 106 is sealed. The upper drive rod 112, located above the support frame 101, is then driven by a motor 118 mounted on the support frame 101 to rotate. Figure 2 As shown, both the upper drive rod 112 and the lower connecting rod 114 have an approximately Z-shaped structure. The upper end of the upper drive rod 112 and the lower end of the lower connecting rod 114 are rotatably mounted on the support frame 101, thereby driving the upper drive rod 112 to rotate around the axis that contacts the support frame 101. This axis is the same as the axis of the lower connecting rod 114 at the end that contacts the support frame 101, that is, the axis of the upper drive rod 112 at the upper end and the axis of the lower connecting rod 114 at the lower end are collinear. When the upper drive rod 112 rotates around its upper axis, the lower end of the upper drive rod 112 drives the entire drying chamber 106 to rotate around the aforementioned axis as well. The upper end of the lower connecting rod 114 contacts the lower connecting cover 113, thereby supporting the drying chamber 106 through the fixed connection between the lower connecting cover 113 and the drying chamber 106. The rotational setting of the lower connecting rod 114 on the support frame 101 and its collinearity with the upper drive rod 112 promotes the rotation of the drying chamber 106. As a result, the center of gravity of the drying chamber 106 is located on the rotation axis of the upper drive rod 112 and the lower connecting rod 114. By tilting and rotating the drying chamber 106, the Chinese medicine inside the drying chamber 106 can be fully shaken, separating the Chinese medicines that are stuck together, preventing them from sticking together and ensuring the drying effect.
[0031] When the drying chamber 106 shakes, the effects of the traditional Chinese medicine will cause the drying chamber 106 to be subjected to a large force in the outward tilting direction. Prolonged use will reduce the service life of the equipment and eventually cause the drying chamber 106 to fall off. Therefore, it is necessary to support and restrict the rotation of the drying chamber 106 to reduce the force in the tilting direction of the drying chamber 106 and prevent the drying chamber 106 from tilting.
[0032] Specifically, a frame 105 is fitted onto the drying oven 106, with the frame 105 not obstructing the pre-set opening of the drying oven 106 to avoid affecting the handling of Chinese medicine. A rotating shaft 104 is fixedly installed on both sides of the frame 105, and a sliding rod 103 is rotatably connected to each shaft. The sliding rods 103 on both sides are respectively connected to vertical slides 102 fixed on both sides of the support frame 101. Therefore, when the drying oven 106 rotates, because the drying oven 106 is in an inclined state, the drying oven 106 will cause the frame 105 to tilt in a certain direction, and this tilting direction will change with the rotation of the drying oven 106; that is, the path of the change in tilting direction matches the path of the rotation of the drying oven 106. When the position of the frame 105 changes, the frame 105 drives the sliding rods 103 on both sides to slide up and down on the vertical slides 102 via the rotating shafts 104.
[0033] like Figure 2 As shown, when the frame 105 changes its tilt direction or angle, the frame 105 slides up and down on the vertical slide 102 via the pivot 104 and the slide rod 103. When the frame 105 changes its front-back direction or angle, because the slide rod 103 is restricted by the vertical slide 102, the frame 105 is rotated and connected to the slide rod 103 via the pivot 104, so that the frame 105 moves with the drying box 106. The frame 105 rotates relative to the drying box 106, thereby adapting to changes in the front-back direction and the tendency to move in the forward and backward directions.
[0034] When the slide bar 103 moves up and down on the vertical slide 102, it is driven by the assist component, while the resistance component is provided with elasticity. When both sides are on the same horizontal plane, no pushing or pulling force is applied to the slide bar 103. This same horizontal plane refers to the horizontal plane where the slide bar 103 is positioned relative to the horizontal state of the support frame 101, and is also the position where the slide bar 103 is perpendicular to the vertical slide 102. Figure 2 As shown, at this time, the right slide bar 103 reaches its uppermost position, and the left slide bar 103 reaches its lowermost position. As a result, the left assist component stretches the slide bar 103 relative to its horizontal state, thus applying a pulling force to the slide bar 103, which in turn helps the slide bar 103 slide upward, causing the rotating shaft 104 and the frame 105 to tend to move the drying chamber 106 in the front-back direction. On the other hand, the right assist component applies a pushing force to the slide bar 103, which also causes the rotating shaft 104 and the frame 105 to tend to move the drying chamber 106 in the front-back direction. Thus, the two sides work together to assist the rotation of the drying chamber 106, and also limit the rotation of the drying chamber 106 by supporting the slide bar 103 and the frame 105, so as to prevent the drying chamber 106 from tilting excessively.
[0035] like Figure 2 and Figure 3As shown, the assist component includes an assist rod 108, a spring 109, and an assist ball 110. The assist rod 108 is slidably mounted on the support frame 101, and the spring 109 is sleeved on the assist rod 108. The assist rod 108 is fixedly connected to the assist ball 110, and both ends of the spring 109 are fixedly connected to the support frame 101 and the assist ball 110, respectively.
[0036] Specifically, the assist component achieves the sliding of the assist ball 110 on the slide groove of the slide rod 103. When the slide rod 103 moves up and down, and gradually switches between the tilted and horizontal states, the contact position between the slide rod 103 and the assist component, i.e. the assist ball 110, also changes accordingly. During this process, the slide rod 103 drives the assist ball 110 to move up and down, thereby stretching or pushing the spring 109 on the assist ball 110, and causing the assist rod 108 to slide on the support frame 101.
[0037] like Figure 3 As shown, the assist ball 110 is slidably disposed on the groove of the slide rod 103. The slide rod 103 and the assist ball 110 are configured to cooperate with each other, and the slide rod 103 forms a semi-enclosed state on the assist ball 110 to restrict the assist ball 110 from detaching from the direction perpendicular to the slide rod 103, while allowing the assist ball 110 to slide along the extension direction of the slide rod 103.
[0038] The slide bar 103 includes two opposing limiting parts that partially enclose the assist ball 110 from both sides, with a sliding gap between the limiting parts and the sides of the assist ball 110. The limiting parts are either protruding structures extending from the inner wall of the slide bar 103 or retaining edges formed by folding the sides of the groove of the slide bar 103 inwards. A suitable sliding mating surface is formed between the outer peripheral surface of the assist ball 110 and the inner surface of the slide bar 103, extending along the extension direction of the slide bar 103. This arrangement ensures that the assist ball 110 slides on the slide bar 103 without detaching from it, thereby utilizing the assist rod 108 and the spring 109 to exert a reaction force on the slide bar 103, i.e., to support and restrict it.
[0039] like Figure 3 As shown, the drying oven 106 is equipped with a detachable door panel 107.
[0040] Specifically, a door panel 107 is installed at the pre-set opening of the drying oven 106 to seal the drying oven 106, which facilitates the handling of Chinese medicine. The door panel 107 is installed with the drying oven 106 by a locking block to ensure the stability of the drying oven 106 when it rotates.
[0041] like Figure 1 and Figure 2As shown, a hot air blower 115 is installed on the support frame 101, and the air nozzle of the hot air blower 115 is connected to the lower connecting rod 114.
[0042] Specifically, the hot air blower 115 includes an electric heating wire and a blower to generate hot air. The hot air is delivered to the hollow pipe of the lower connecting rod 114 through the opening at the end of the support frame 101. The hot air is then sprayed out of the lower connecting cover 113 and the drying box 106 through the lower connecting rod 114, and then comes into contact with the shaking Chinese medicine to achieve a drying effect. After passing through the Chinese medicine, the airflow is discharged from the upper end of the drying box 106, i.e., the upper connecting cover 111.
[0043] like Figure 3 As shown, the upper connecting cover 111 has multiple narrow ventilation slots near the upper drive rod 112.
[0044] Specifically, when the Chinese medicine in the drying oven 106 is being dried, hot air is discharged through the upper connecting cover 111 on the drying oven 106, and the hot air is slowly discharged through the relatively narrow ventilation slot on the upper connecting cover 111, reducing the speed at which the hot air leaves, so that the inside of the drying oven 106 is heated by the hot air, increasing the time the heat exists, and ensuring the drying effect.
[0045] like Figure 4 and Figure 5 As shown, a guide plate 116 is provided on the inner wall of the lower connecting cover 113, and multiple ventilation slots are provided where the guide plate 116 contacts the lower connecting cover 113. The guide plate 116 is arched, with the side away from the lower connecting rod 114 protruding towards the drying chamber 106, and the side closer to the lower connecting rod 114 recessed towards the guide plate 116, thereby using the concave arc shape to guide the movement of hot air and discharge it from the ventilation slots around the guide plate 116.
[0046] Specifically, when the hot air from the hot air blower 115 enters the drying chamber 106 through the lower connecting rod 114, it first moves to the surroundings within the lower connecting cover 113 by the restriction of the guide plate 116, thereby causing the hot air to gradually move upwards from the surroundings. Because the drying chamber 106 is tilted and swaying, the Chinese medicine adheres to the inner wall of the drying chamber 106 instead of gathering in the middle, thus moving upwards from the surroundings, which can increase the contact between the hot air and the Chinese medicine, thereby providing a drying effect.
[0047] like Figure 4 As shown, multiple filters 117 for separation are fixedly installed on the drying chamber 106. Specifically, by setting multiple filters 117 inside the drying chamber 106 to separate the Chinese medicine, it is avoided that the Chinese medicine will accumulate in large quantities inside the drying chamber 106, which would hinder the movement of hot air.
[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
