Description

Technical Field

[0001] This utility model relates to the field of carbonization equipment technology, and more specifically, to a drying tray for processing Forsythia suspensa. Background Technology

[0002] Forsythia, a commonly used bulk Chinese medicinal herb, has its quality directly affecting its clinical efficacy. In the processing of forsythia at its place of origin, freshly harvested forsythia must undergo timely drying to remove excess moisture, prevent mold, and retain its active ingredients to the maximum extent. Drying is a crucial step that determines the color, shape, and medicinal efficacy of the finished forsythia product.

[0003] Currently, in the large-scale processing of Forsythia suspensa, drying rooms or multi-layer trolley dryers are commonly used. A search revealed a utility model patent with authorization announcement number CN215002701U, which discloses a drying tray for traditional Chinese medicine, belonging to the field of traditional Chinese medicine processing technology. This drying tray includes a drying box assembly and a tray assembly. The tray assembly is disposed within the drying box assembly and includes a support frame, a bracket frame, a slide rail, a tray component, a slewing bearing, and a drive motor. By pulling the slide rail at one end of the tray component away from the T-shaped slide rail, so that the slide rail at the other end of the tray component is located outside the bracket frame, the tray component is rotated.

[0004] However, most existing drying trays are fixed, perforated structures. During prolonged static drying, thicker layers of forsythia tend to clump together under their own weight and the influence of hot, humid airflow. This makes it difficult for hot air to penetrate the material evenly, resulting in localized areas of the material becoming mushy, discolored, or even moldy, while the surface material becomes over-dried and scorched. This uneven drying not only damages the appearance of the finished product but also leads to a significant loss of active ingredients. Furthermore, when traditional drying trays are stacked in multiple layers, the ventilation gaps between layers are often maintained by simple supports, lacking an effective locking mechanism. This makes them prone to shaking or misalignment during handling or when subjected to airflow impacts within the equipment, resulting in poor stability. Therefore, improvements are needed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a solution that overcomes or at least partially solves the above technical problems.

[0006] This utility model provides a drying tray for processing Forsythia suspensa, comprising two outer frames. A hollowed-out disc is fixedly connected to the inner wall of each outer frame. A rotating sleeve is installed in the middle of the hollowed-out disc via a bearing. A turning mechanism is provided on the rotating sleeve. Two clamps are fixedly connected to the bottom of the outer frame. Two support rods are fixedly connected to the upper end of the outer frame. The positions of the support rods correspond to the positions of the clamps. The upper clamp is engaged with the top of the lower support rod. A buckle plate is hinged to the side of the clamp. A rubber bead is fixedly connected to the buckle plate and engages with the column of the support rod.

[0007] In a preferred embodiment, the upper side of the support rod has a notch, the position of which corresponds to the position of the locking head.

[0008] In a preferred embodiment, the outer ring wall of the outer frame is fixedly connected to two symmetrically arranged handles, each of which is covered with a heat insulation sleeve.

[0009] In a preferred embodiment, the material turning mechanism includes a polygonal shaft that is inserted into a rotating sleeve. A rotating column is fixedly connected to the top of the polygonal shaft. A connecting frame is fixedly connected to the shaft of the rotating column, and the connecting frame is L-shaped. A connecting strip is fixedly connected to the vertical end of the connecting frame. A vertical rod is fixedly connected to the bottom of the connecting strip. A shovel is fixedly connected to the end of the vertical rod. The shovel is slidably connected to the upper surface of the hollow disc.

[0010] In a preferred embodiment, the inside of the rotating sleeve has a polygonal slot, and the polygonal shaft is inserted into the polygonal slot.

[0011] In a preferred embodiment, the number of vertical bars is set to multiple, and the multiple vertical bars are distributed in a straight line along the length direction of the connecting bar.

[0012] In a preferred embodiment, a handle is fixedly connected to the column body of the rotating column, and the position of the handle is symmetrical to the position of the connecting frame.

[0013] In a preferred embodiment, the end of the handle is provided with a bent portion, and the end of the bent portion is integrally formed with a sphere.

[0014] The targeted solution provided by this utility model has the following beneficial effects:

[0015] 1. This solution uses a turning mechanism consisting of a polygonal shaft, rotating column, connecting frame, and shovel to manually turn the Forsythia suspensa laid on the perforated tray periodically during the drying process. This effectively breaks up the accumulation and compaction of the material caused by static placement, ensuring that the hot airflow can evenly penetrate every layer of the material, thereby significantly improving the uniformity of drying. This not only avoids localized "staleness" or scorching, protecting the color and efficacy of the Forsythia suspensa, but also shortens the overall drying cycle and increases processing capacity by optimizing heat exchange efficiency. In addition, the detachable structure facilitates use.

[0016] 2. This solution achieves rapid and stable stacking and locking of multiple drying tray units by setting a locking head at the bottom of the outer frame and a support rod with a notch at the top, along with hinged buckles and rubber locking beads. This connection method ensures stable and sufficient ventilation gaps between layers while effectively preventing misalignment or slippage caused by vibration during handling or drying, greatly improving safety and stability, and is especially suitable for multi-layer, batch operations in large-scale drying equipment.

[0025] Example

[0026] Reference Figure 1 , Figure 2 , Figure 4 This utility model provides a technical solution: a drying tray for processing Forsythia suspensa, comprising two outer frames 1, each outer frame 1 having a perforated tray 2 fixedly connected to its inner wall, and two symmetrically arranged handles 9 fixedly connected to the outer wall of the outer frame 1, each handle 9 being covered with a heat insulation sleeve 10. By providing handles 9 with heat insulation sleeves 10 on the outer wall of the outer frame 1, it is convenient for workers to move the entire assembly into the drying equipment.

[0027] Reference Figure 3 Two clips 5 are fixedly connected to the bottom of the outer frame 1, and two support rods 6 are fixedly connected to the upper end of the outer frame 1. The positions of the support rods 6 correspond to the positions of the clips 5. The upper clip 5 engages with the top of the lower support rod 6. A buckle plate 7 is hinged to the side of the clip 5, and a rubber bead 8 is fixedly connected to the buckle plate 7. The rubber bead 8 engages with the column of the support rod 6. A notch is opened on the upper side of the support rod 6, and the position of the notch corresponds to the position of the clip 5. An insertion hole corresponding to the contour of the clip 5 is opened on the top of the support rod 6, and the notch is located on the wall of the insertion hole, which facilitates the flipping of the buckle plate 7.

[0028] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5A rotating sleeve 3 is installed in the middle of the hollow disc 2 via a bearing. A turning mechanism 4 is provided on the rotating sleeve 3. A polygonal shaft 41 is inserted into the rotating sleeve 3. In this way, the polygonal shaft 41 can rotate around the rotating sleeve 3 as the axis, thereby driving the connecting frame 43, the vertical rod 45 and the shovel 46 to shovel the forsythia on the hollow disc 2, maintaining ventilation between the upper and lower layers. Uniform ventilation avoids "staleness" and scorching, ensuring the color and efficacy of the forsythia. At the same time, the efficient ventilation design makes the heat energy utilization rate higher, thereby significantly shortening the drying time and increasing the production capacity. The turning mechanism 4 includes a polygonal shaft 41, which is inserted into the rotating sleeve 3. A polygonal slot is opened inside the rotating sleeve 3, and the polygonal shaft 41 is inserted into the polygonal slot. The contour of the polygonal slot is the same as the outer contour of the polygonal shaft 41, so that after the polygonal shaft 41 is inserted into the rotating sleeve 3, it can rotate together with the rotating sleeve 3. A rotating column 42 is fixedly connected to the top of the polygonal shaft 41, and a connecting frame 43 is fixedly connected to the shaft of the rotating column 42. The connecting frame 43 is L-shaped, and a connecting strip 44 is fixedly connected to the vertical end of the connecting frame 43. A vertical rod 45 is fixedly connected to the bottom of the connecting strip 44. Multiple vertical rods 45 are provided, and the multiple vertical rods 45 are distributed in a straight line along the length of the connecting strip 44. By setting multiple vertical rods 45, it can be used to comb the tangled hairs on the hollow plate 2. A scraper 46 is fixedly connected to the end of the vertical rod 45, and the scraper 46 is slidably connected to the upper surface of the hollow plate 2. A handle 47 is fixedly connected to the column of the rotating column 42, and the position of the handle 47 is symmetrical with the position of the connecting frame 43. The handle 47 makes it easy for the operator to rotate the rotating column 42. The handle 47 has a bent portion at its end, and a ball is integrally formed at the end of the bent portion. By incorporating the bent portion and the ball into the handle 47, a comfortable grip angle is provided for the operator.

[0029] Working method: When using, first hold handle 9 and place the drying tray on the workbench. Then, evenly spread the harvested and processed Forsythia on the perforated tray 2. Next, lift the second drying tray filled with material, aligning the two clips 5 at the bottom with the insertion holes on the two support rods 6 at the top of the lower drying tray, and place it downwards. After the clips 5 are inserted into the insertion holes, the upper drying tray is supported by its support rods 6 on the outer frame 1 of the lower drying tray, naturally forming a stable ventilation gap between the two layers. Flip the buckle plate 7 on the side of the clip 5 of the upper drying tray upwards so that it is fastened to the column of the lower support rod 6. At this time, the rubber beads 8 on the buckle plate 7 are tightly locked into the side of the support rod 6 under the action of elasticity. This mechanism achieves vertical locking to prevent interlayer displacement. The stacked and locked drying trays are then pushed into the drying room or drying equipment. During the drying process, the operator can periodically insert the polygonal shaft 41 in the turning mechanism 4 into the rotating sleeve 3 on the hollow tray 2. Then, the handle 47 drives the polygonal shaft 41 and the rotating column 42 to rotate. The shovel 46 will turn the bottom layer of forsythia to the top layer as it rotates, breaking up the hardened material and ensuring uniform drying. After drying, the buckle plate 7 is opened to release the rubber ball 8 from the support rod 6, thus separating the drying trays. Finally, the polygonal shaft 41 is pulled out, and the turning mechanism 4 can be removed as a whole for thorough cleaning and maintenance of the hollow tray 2 and the shovel 46.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
