Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine decoction piece drying technology, and in particular relates to a material turning mechanism for a traditional Chinese medicine decoction piece drying box. Background Technology

[0002] Chinese medicinal herbs are processed medicinal materials that have been processed according to the theories and methods of traditional Chinese medicine and can be used directly in clinical practice. The drying oven for Chinese medicinal herbs can quickly remove moisture from the herbs to prevent mold and spoilage, meet specific processing requirements, improve production efficiency, ensure uniform and stable quality of the herbs, and facilitate storage, transportation and subsequent processing.

[0003] Currently, existing drying ovens have simple structures and usually use a simple static flat-laying method to dry medicinal slices. During this process, the medicinal slices are statically piled up due to the lack of an active turning mechanism, resulting in insufficient internal heat transfer. This not only prolongs the drying cycle and reduces the drying efficiency of the medicinal slices, but may also cause uneven distribution of moisture content (overly dry surface, damp interior), which in turn leads to the risk of mold growth or loss of effective ingredients, affecting the quality of Chinese medicinal slices.

[0004] To address the aforementioned issues, this application proposes a material turning mechanism for a drying oven for Chinese herbal medicine slices. Utility Model Content

[0005] The purpose of this invention is to provide a turning mechanism for a drying box for Chinese herbal medicine slices, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a turning mechanism for a drying box for Chinese herbal medicine pieces. It includes a drying box and two turning rakes symmetrically arranged inside the drying box. The drying box contains two placement mesh cylinders. The two turning rakes are respectively positioned above the placement mesh cylinders, and each turning rake has a connecting shaft fixed to its top. The connecting shaft drives the turning rakes to rotate. Two lifting seats are symmetrically arranged inside the drying box, and each lifting seat has a lifting mechanism connected to its bottom end. A fixed seat is fixed to the lower outer wall of the placement mesh cylinder. The top surface of the lifting seat has a placement groove for accommodating the fixed seat. A collection drawer is slidably provided on the side wall of the lifting seat. The lifting seat has a communicating groove communicating with the placement groove. The collection drawer is used to collect fragments of Chinese herbal medicine pieces.

[0008] Furthermore, the bottom plate of the drying oven is fixed with a vertical fixed column, and a cavity two is opened in the fixed column. A driving bevel gear is provided in the cavity two, and a bevel gear three meshes with each of the two sides of the driving bevel gear. An outer protective shell is fixed on both sides of the fixed column. The bevel gear three is fixedly connected to the bevel gear two in the outer protective shell through a connecting shaft two that passes through the fixed column. A bevel gear one that meshes with the bevel gear two is provided in the outer protective shell. The connecting shaft one passes through the bottom end of the outer protective shell and is fixedly connected to the bevel gear one.

[0009] Furthermore, a fixed base is fixedly provided at the bottom of the drying oven, and a motor is fixedly provided inside the fixed base. The output end of the motor is coaxially fixed with the active bevel gear.

[0010] Furthermore, the lifting mechanism includes a lifting plate, which is disposed in a cavity opened in the fixed base. The top of the lifting plate is fixedly connected to the lifting seat through two smooth rods penetrating the bottom of the drying box. A rotating shaft is rotatably installed between the bottom surface of the cavity and the bottom surface of the drying box, and the outer wall of the rotating shaft is provided with a threaded section that is threadedly connected to the lifting plate.

[0011] Furthermore, a bevel gear four is fixedly provided on the outer wall of the lower end of the rotating shaft, and the bevel gear four is meshed with a bevel gear five. The bevel gear five is fixedly connected to a handwheel outside the fixed base through a connecting shaft three.

[0013] Furthermore, a handrail is fixedly provided on one side of the fixed base, and the lifting base is provided with a clearance groove for avoiding the handrail.

[0014] Furthermore, a positioning groove is provided on the bottom surface of the fixed base, and a positioning block that cooperates with the positioning groove is fixed in the placement groove.

[0015] This utility model has the following beneficial effects:

[0016] This invention uses two turning rakes to simultaneously turn over the Chinese herbal medicine slices placed in two mesh cylinders, so that the slices are constantly stirred and moved during the drying process, thereby ensuring that hot air penetrates the slice layer more evenly, significantly improving the uniformity of drying, and effectively preventing the slices from clumping due to uneven heating or local moisture accumulation.

[0017] When the medicinal slices are turned over by the turning rake, the debris mixed in with the slices will fall down through the mesh of the mesh tube, preventing the debris from mixing into the whole slices and affecting the quality of the finished product. The collection drawer automatically collects the debris mixed in with the medicinal slices, preventing the debris from accumulating at the bottom of the drying chamber and keeping the chamber clean.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figure 1 - Figure 5 As shown, this utility model is a turning mechanism for a drying box for Chinese herbal medicine pieces, including a drying box 1 and two turning rakes 6 symmetrically arranged inside the drying box 1. The drying box 1 is provided with two placement mesh cylinders 4. The two turning rakes 6 are respectively positioned above the placement mesh cylinders 4, and the top of each turning rake 6 is fixed with a connecting shaft 601. The connecting shaft 601 drives the turning rake 6 to rotate. Two lifting seats 3 are symmetrically arranged inside the drying box 1. The bottom ends of the two lifting seats 3 are respectively connected to lifting mechanisms. The lower outer wall of the placement mesh cylinder 4 is fixed with a fixed seat 5. The top surface of the lifting seat 3 is provided with a placement groove 301 for accommodating the fixed seat 5. The side wall of the lifting seat 3 is slidably provided with a collection drawer 18. The lifting seat 3 is provided with a connecting groove 302 communicating with the placement groove 301. The collection drawer 18 is used to collect the fragments of Chinese herbal medicine pieces.

[0030] This embodiment provides a turning mechanism for a drying box for Chinese herbal medicine slices. The placing mesh cylinder 4 is a mesh cylinder with an open top, used to hold Chinese herbal medicine slices. The connecting shaft 601 drives the turning rake 6 to rotate, so that the rake teeth of the turning rake 6 turn the Chinese herbal medicine slices placed in the placing mesh cylinder 4. During the turning of the Chinese herbal medicine slices, some debris may be generated. The debris falls into the collection drawer 18 through the connecting groove 302 after passing through the mesh of the placing mesh cylinder 4, realizing automatic collection of debris. After the Chinese herbal medicine slices are dried, the placing mesh cylinder 4 and the lifting seat 3 are moved down by the lifting mechanism to facilitate the removal of the placing mesh cylinder 4, so that the placing mesh cylinder 4 is away from the turning rake 6, making it easy to remove the placing mesh cylinder 4 and pour out the dried slices.

[0031] The drying oven 1 has a vertical fixed column 11 fixed to its bottom plate, and a cavity 1101 is formed inside the fixed column 11. A driving bevel gear 10 is installed inside the cavity 1101, and a bevel gear 9 meshes with each of its two sides. Outer shells 12 are fixed to both sides of the fixed column 11. The bevel gears 9 are connected to the bevel gears 8 inside the outer shell 12 via connecting shafts 901 that pass through the fixed column 11. The outer shell 12 also contains a bevel gear 1 that meshes with the bevel gear 8. 7. The connecting shaft 601 passes through the bottom end of the outer shell 12 and is fixedly connected to the bevel gear 7. The bottom end of the drying box 1 is fixedly provided with a fixed base 2, and a motor 17 is fixedly provided inside the fixed base 2. The output end of the motor 17 is coaxially fixed with the active bevel gear 10. The motor 17 drives the active bevel gear 10 to rotate, thereby driving the two bevel gears 9 to rotate. Furthermore, the bevel gear 8 drives the bevel gear 7 to rotate, thereby realizing the synchronous rotation of the two turning rakes 6 and turning the medicinal slices placed in the two placing net cylinders 4 at the same time.

[0032] The lifting mechanism includes a lifting plate 13, which is set in a cavity 201 opened in the fixed base 2. The top of the lifting plate 13 is fixedly connected to the lifting seat 3 through two smooth rods 1301 that pass through the bottom of the drying box 1. A rotating shaft 14 is rotatably installed between the bottom surface of the cavity 201 and the bottom surface of the drying box 1. The outer wall of the rotating shaft 14 is provided with a threaded section 1401 that is threadedly connected to the lifting plate 13. When the rotating shaft 14 rotates, it drives the lifting plate 13 to rise and fall, and further drives the lifting seat 3 to rise and fall synchronously through the smooth rods 1301.

[0033] The lower outer wall of the rotating shaft 14 is fixed with a bevel gear 4 15, and the bevel gear 4 15 is meshed with a bevel gear 5 16. The bevel gear 5 16 is fixed to a handwheel outside the fixed base 2 through a connecting shaft 3 1601. By rotating the handwheel, the bevel gear 5 16 can be driven to rotate, thereby driving the rotating shaft 14 to rotate through the bevel gear 4 15.

[0034] The bevel gear 15 is provided with a limiting plate 1402 fixed to the outer wall of the rotating shaft 14. The limiting plate 1402 blocks the lifting plate 13 to prevent the lifting plate 13 from contacting or bumping with the bevel gear 15.

[0035] The fixed base 5 has a hand handle 502 fixed on one side, and the lifting base 3 has a clearance groove 304 for avoiding the hand handle 502, so that the user can easily remove the lifting base 3 by using the hand handle 502.

[0036] The fixed base 5 has a positioning groove 501 on its bottom surface, and a positioning block 303 that cooperates with the positioning groove 501 is fixed in the placement groove 301. The positioning block 303 cooperates with the positioning groove 501 to position the lifting base 3 and the placement mesh cylinder 4, preventing the placement mesh cylinder 4 from shifting when turning over the material.

[0037] Understandably, this invention can turn over the Chinese herbal medicine slices to ensure that the slices are heated evenly and improve the drying efficiency. Secondly, it can collect the broken pieces of Chinese herbal medicine slices to prevent the broken pieces from mixing into the slices or piling up and affecting the drying effect.

[0038] A specific application of the operation process of this embodiment is as follows: Take out the placement net cylinder 4 and put in the Chinese medicine decoction pieces, then place the placement net cylinder 4 on the lifting seat 3, turn the handwheel, and drive the rotating shaft 14 to rotate through the bevel gear 5 16 and bevel gear 4 15, thereby driving the lifting plate 13 to move upward, and further drive the lifting seat 3 and the placement net cylinder 4 to move upward through the smooth rod 1301, so that the rake teeth of the turning rake 6 extend into the placement net cylinder 4;

[0039] When the medicinal slices are drying, the motor 17 drives the active bevel gear 10 to rotate, and the bevel gears 9 on both sides rotate accordingly. The bevel gear 8 inside the outer shell 12 rotates through the connecting shaft 901. The bevel gear 8 drives the bevel gear 7 and the connecting shaft 601 to rotate, and finally drives the turning rake 6 to rotate through the connecting shaft 601, thereby turning the medicinal slices in the mesh cylinder 4.

[0040] The dregs mixed in with the Chinese herbal medicine slices will pass through the mesh of the mesh tube 4 and fall into the connecting groove 302 of the lifting seat 3, and slide into the collection drawer 18. When it is necessary to clean the dregs, the collection drawer 18 can be pulled out to pour out the dregs, which is convenient to operate.
