One side of the drying drum 101 is connected to a rotating motor 102, and a feeding port 103 is provided on the top of the drying drum 101, and a filter 104 is connected to the feeding port 103. Multiple feeding ports 103 can be set. When the drying drum 101 is working, the filter 104 can filter the moisture in the Chinese medicinal materials. In order to facilitate the staff to install the filter 104, positioning grooves 307 are provided on both sides of the feeding port 103, and positioning blocks 308 are provided on both sides of the filter 104, and the positioning blocks 308 are slidably connected to the inner wall of the positioning groove 307.

At the same time, the filter 104 can be installed at the feeding port 103 by bolts.
[0026] The output end of the rotating motor 102 is fixedly connected to the first rotating shaft 105, and the first rotating shaft 105 extends to the inside of the drying drum 101, and the end of the first rotating shaft 105 away from the drying drum 101 is fixedly connected to at least one rotating plate 106 (it should be noted here that multiple rotating plates 106 can be provided, and multiple rotating plates 106 can be formed as one piece. This embodiment takes four rotating plates 106 as an example, but the number is not limited). A heating tube 107 is provided on the side of the rotating plate 106 away from the rotating motor 102, and the heating tube 107 extends to the other side of the drying drum 101. The rotating plate 106 and the drying drum 101 are both linked to the rotating motor 102.
[0027] When in use, first open the filter 104, then put the Chinese medicinal materials into the drying drum 101 through the feed port 103, then fix the filter 104, and finally start the rotating motor 102. When the rotating motor 102 is started, its output end will drive the drying drum 101 and the rotating plate 106 to rotate simultaneously through the first rotating shaft 105. At the same time, the heating tube 107 will also follow the rotation, extending one end of the heating tube 107 to the other side of the drying drum 101 to ensure that the heat received by the medicinal materials is evenly distributed during the entire heating process, thereby improving the drying efficiency of the drying equipment. In addition, the rotation of the heating tube 107 also helps to break up the medicinal materials accumulated inside the drying drum 101, making the distribution of the medicinal materials more even, further improving the drying effect. At the same time, linking the rotating plate 106 and the drying drum 101 with the rotating motor 102 can reduce the production cost of the drying equipment and improve energy utilization efficiency.
[0028] Furthermore, a motor base 2 is provided on the top of the bracket 1, and the rotating motor 102 is arranged on the motor base 2 and fixedly connected to the motor base 2. The rotating motor 102 can be fixedly connected to the motor base 2 by bolts, and the threaded connection method can facilitate the operator to disassemble the rotating motor 102, which is convenient for the operator to maintain. The first rotating shaft 105 is rotatably connected to the drying cylinder 101, and a rotating groove 302 is provided on the side of the drying cylinder 101 close to the rotating motor 102. A rolling bearing 303 is provided in the rotating groove 302. The first rotating shaft 105 is fixedly connected to the inner ring of the rolling bearing 303. The rolling bearing 303 is a deep groove ball bearing. The deep groove ball bearing has a simple structure, light weight, and low friction, which can reduce the friction between the first rotating shaft 105 and the drying cylinder 101, thereby improving the operating efficiency of the first rotating shaft 105.
[0029] A first gear 201 is provided on the side of the first rotating shaft 105 away from the rotating plate 106, and the first gear 201 is arranged between the drying drum 101 and the rotating motor 102, and is fixedly connected to the first rotating shaft 105. The side of the motor base 2 close to the drying drum 101 is rotatably connected to the second gear 203 through the second rotating shaft 202, and the first gear 201 is meshed with the second gear 203. A first inner gear ring 204 is provided on the side of the drying drum 101 close to the rotating motor 102, and the first inner gear ring 204 is fixedly connected to the drying drum 101, and the second gear 203 is meshed with the first inner gear ring 204.
[0030] When the rotating motor 102 rotates, its output end will drive the first rotating shaft 105 to rotate clockwise, and the first rotating shaft 105 will drive the rotating plate 106 and the heating tube 107 on the rotating plate 106 to rotate clockwise. At the same time, the first gear 201 will also rotate clockwise. Since the first gear 201 is engaged with the second gear 203, the second gear 203 will rotate counterclockwise. However, when the second gear 203 rotates counterclockwise, the second gear 203 will drive the first inner gear ring 204 to rotate counterclockwise, thereby driving the drying cylinder 101 to rotate counterclockwise, rotating the heating tube 107 and the drying cylinder 101 in the same direction, which helps to mix the medicinal materials in the drying cylinder 101 and ensure that the medicinal materials are fully exposed to the hot air flow, thereby achieving more uniform drying, preventing local overheating or incomplete drying caused by accumulation of medicinal materials, improving drying efficiency, and at the same time, it can prevent the medicinal materials from sticking together during the drying process, ensuring the uniformity of the drying of the medicinal materials.
[0031] Furthermore, the side of the rotating plate 106 away from the rotating motor 102 is rotatably connected to the third gear 3, the heating tube 107 is arranged on the side of the third gear 3 away from the rotating plate 106, and is fixedly connected to the third gear 3, the inner wall of the drying drum 101 is fixedly connected to the second inner gear ring 301, and the second inner gear ring 301 is meshed with the third gear 3. When the rotating plate 106 rotates clockwise and the drying drum 101 rotates counterclockwise, the counterclockwise rotation of the drying drum 101 will drive the second inner gear ring 301 to rotate counterclockwise. Since the third gear 3 is meshed with the second inner gear ring 301, Therefore, the third gear 3 will rotate, thereby driving the heating tube 107 to rotate (the specific principle can be explained as the third gear 3 revolves around the first rotating shaft 105, and while the third gear 3 revolves, it can also rotate on its own). Rotating the heating tube 107 itself can reduce the friction between the medicinal materials and the heating tube 107, reduce the possibility of the medicinal materials adhering to and burning the surface of the heating tube 107, and help maintain the quality and purity of the medicinal materials (in addition, a baffle 5 is fixedly connected to the side of the rotating plate 106 away from the rotating motor 102 through a plurality of connecting columns 501). , and the baffle 5 is rotatably connected to the inside of the drying drum 101. A number of through holes are opened on the baffle 5 for allowing the heating tube 107 to pass through, and the heating tube 107 is rotatably connected to the through holes. The baffle 5 can separate the medicinal materials from the second inner gear ring 301 to prevent the medicinal materials from interfering with the engagement of the second inner gear ring 301 with the third gear 3. When the rotating plate 106 rotates clockwise, the rotating plate 106 will drive the baffle 5 to rotate synchronously through a number of connecting columns 501 (when the heating tube 107 rotates, only the outer tube of the heating tube 107 rotates, and the internal heating wire does not rotate. Since the heating tube The connection between the heating tube 107 and the power cord can be made by setting a slip ring at the rotation center of the drying drum 101 to maintain the power supply of the heating tube 107. The slip ring is an electrical component responsible for connecting the rotating body and transmitting energy and signals. It is usually installed at the rotation center of the equipment and consists of two major parts: rotating and stationary. The rotating part is connected to the rotating structure of the equipment and rotates with it, which is called the "rotor"; the stationary part is connected to the energy of the fixed structure of the equipment, which is called the "stator". As long as the slip ring is attached to the rotating equipment, it can provide power to the rotating body).
[0032] In this embodiment, sliding rings 304 are provided on both sides of the drying drum 101, and several pulley 306 mechanisms are provided on the top of the bracket 1, and each pulley 306 mechanism is respectively arranged on both sides of each sliding ring 304. The pulley 306 mechanism includes a pulley 306 and two fixed blocks 305. The two fixed blocks 305 are both arranged on the top of the bracket 1 and fixedly connected to the bracket 1. The pulley 306 is arranged between the two fixed blocks 305 and is rotatably connected to the two fixed blocks 305. The sliding ring 304 is slidably connected to the pulley 306.
[0033] The pulley 306 can provide additional support to help the drying drum 101 rotate smoothly. At the same time, it can also reduce friction and resistance. The pulley 306 can ensure that the drying drum 101 runs more smoothly during rotation, reduce vibration and noise, and improve the stability of the equipment.
[0034] In order to facilitate the staff to collect the dried medicinal materials, a collection box 4 is provided at the bottom of the bracket 1. The collection box 4 is tilted by a number of support rods 401. The tilted collection box 4 can make the dried medicinal materials accumulate in one place under the influence of gravity, making it easier for the staff to collect them.
[0035] Working principle:
[0036] When in use, first open the filter 104, then put the Chinese medicinal materials into the drying drum 101 through the feed port 103, then fix the filter 104, and finally start the rotating motor 102. When the rotating motor 102 rotates, its output end will drive the first rotating shaft 105 to rotate clockwise, and the first rotating shaft 105 will drive the rotating plate 106 and the heating tube 107 on the rotating plate 106 to rotate clockwise. At the same time, the first gear 201 will also rotate clockwise. Since the first gear 201 is engaged with the second gear 203, the second gear 203 will rotate counterclockwise. However, when the second gear 203 rotates counterclockwise, the second gear 203 will drive the first inner gear ring 204 to rotate counterclockwise, thereby driving the drying drum 101 to rotate counterclockwise. At the same time, The counterclockwise rotation of the drying drum 101 will drive the second inner gear ring 301 to rotate counterclockwise. Since the third gear 3 is engaged with the second inner gear ring 301, the third gear 3 will rotate, thereby driving the heating tube 107 to rotate (the specific principle can be explained as the third gear 3 revolving around the first rotating shaft 105, and while the third gear 3 revolves, it can also rotate on its own). After the drying is completed, the operator can use a tool to unscrew the bolts, and then open the filter 104, so that the medicinal materials inside the drying drum 101 fall into the collection box 4, which is convenient for the operator to collect.
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
