[0025] The bearing assembly is installed on the connecting rod 3, and one group of bearing assemblies corresponds to one connecting rod 3. The bearing assembly includes a loading ball 6 and a handle 7. The loading ball 6 includes a sphere 6-1 and a cover 6-2. The sphere 6-1 is a hollow mesh ball, and the sphere 6-1 has an opening 6-1-1. The cover 6-2 is an arc-shaped mesh surface. The inner diameter of the arc-shaped mesh surface of the cover 6-2 is slightly larger than the outer diameter of the sphere 6-1, and the curvature of the arc-shaped mesh surface of the cover 6-2 is larger than the curvature of the opening 6-1-1. Figure 5-7 In the embodiment, the curvature of the opening 6-1-1 is 90°, and the curvature of the curved mesh surface of the cover body 6-2 is approximately 95°. The two sides of the cover body 6-2 are rotatably connected to the sphere 6-1, and two limiting protrusions 6-1-2 are arranged on the outside of the sphere 6-1. The positions of the two limiting protrusions 6-1-2 correspond to the two extreme positions of the cover body 6-2 respectively. When the cover body 6-2 rotates to the position of the limiting protrusion 6-1-2, the cover body 6-2 is engaged with the limiting protrusion 6-1-2. One of the limiting protrusions 6-1-2 corresponds to the maximum position of the cover body 6-2 opening upward, and the side of the cover body 6-2 close to the limiting protrusion 6-1-2 is engaged with the limiting protrusion 6-1-2; the other limiting protrusion 6-1-2 corresponds to the lowest position of the cover body 6-2 closing the opening 6-1-1 of the sphere 6-1 downward, and the cover body 6-2 completely covers the opening 6-1-1, and the side of the cover body 6-2 close to the limiting protrusion 6-1-2 is engaged with the limiting protrusion 6-1-2. When the two limiting protrusions 6-1-2 are respectively engaged with the cover body 6-2, they correspond to the upper and lower sides of the cover body 6-2. One way to engage the cover body 6-2 with the limiting protrusions 6-1-2 is to insert the limiting protrusions 6-1-2 into the mesh of the cover body 6-2.

[0026] The handle 7 is installed on the side of the sphere 6-1 away from the opening 6-1-1. The end of the handle 7 away from the sphere 6-1 has a mounting hole 7-1. The plug 4 is connected and matched with the mounting hole 7-1 of the handle 7. A ball screw 5 is installed on the side of the plug 4. The mounting hole 7-1 of the handle 7 has an arc groove that matches the size and position of the ball screw 5.

[0027] The heating assembly is a heating cylinder, which is mounted on the rotating shaft 2. In fact, the heating cylinder is located in the middle position surrounded by the loading balls 6 of each bearing assembly, so as to be close to the loading balls 6, thereby heating and drying the Chinese medicinal materials loaded on the loading balls 6.

[0028] like Figure 8-9 As shown, it also includes a transfer trolley 8, on which a load-bearing column 9 is installed, and a plurality of load-bearing hooks 10 are distributed on the load-bearing column 9. The load-bearing hook 10 includes an extended section 10-1 and an inclined section 10-2. The extended section 10-1 is perpendicular to the load-bearing column 9, and the inclined section 10-2 extends upward from the extended section 10-1. The extended section 10-1 is connected and matched with the mounting hole 7-1 of the handle 7 in a profile connection, and the inclined section 10-2 is smaller than the inner diameter of the mounting hole 7-1 to facilitate the insertion of the mounting hole 7-1 of the handle 7.

[0029] The heating tube is fixed to the rotating shaft 2 through a bearing, and the heating tube does not rotate with the rotating shaft 2. Each bearing component rotates with the rotating shaft 2, and each bearing component also rotates around the heating tube.

[0030] like Figure 1-2 As shown in 10 , the heating cylinder includes a pair of discs 11 and a plurality of heating rods 12 . The pair of discs 11 are arranged opposite to each other, and the centers of the discs 11 are fixed to the rotating shaft 2 through bearings. The heating rods 12 are evenly distributed around the rotating shaft 2, and the two ends of the heating rods 12 are fixed to the two discs 11 respectively.

[0031] like Figure 1-2 As shown, the rotating assembly includes eight connecting rods 3, each connecting rod 3 is evenly arranged around the rotating shaft 2, and a bearing assembly is installed on each connecting rod 3.

[0032] like Figure 8 As shown, two bearing columns 9 are provided on the transfer trolley 8, and four bearing hooks 10 are provided on each bearing column 9 from top to bottom.

[0033] It also includes a PLC programmable logic controller. A wireless signal transmission module 13 is provided on the drying cylinder 1. A temperature sensor is provided inside the drying cylinder. The temperature sensor is connected to the PLC programmable logic controller signal through the wireless signal transmission module 13. The heating rod 12 is controlled to switch on and off through the PLC programmable logic controller. The wireless signal transmission module 13 can be a Bluetooth module. The temperature sensor transmits the temperature signal to the background. The background remotely wirelessly controls the on and off of the heating rod 12 through the PLC programmable logic controller according to the temperature signal, or controls the heating time of the heating rod 12. The background can remotely control multiple drying cylinders 1 through the PLC programmable logic controller to realize Internet of Things control.

[0034] The intelligent drying system for Chinese herbal medicine slices based on Internet of Things control of the present invention has the following working process:

[0035] 1. The load-bearing assembly is a handle-type loading ball that is easy to remove and install. Remove the load-bearing assembly and open the cover 6-2 of the loading ball 6 until Figure 5In the state shown, the upper end of the cover 6-2 is engaged with the limiting protrusion 6-1-2 of the ball 6-1 near the handle 7, and the cover 6-2 is fixed by the limiting protrusion 6-1-2 and will not fall. Hold the handle 7, scoop a spoonful of Chinese medicinal materials from the raw materials of Chinese medicinal materials into the ball 6-1 of the loading ball 6, and then lower the cover 6-2 to cover the opening 6-1-1 until it is as shown. Figure 6 The cover 6-2 is in a state where the opening 6-1-1 is completely covered by the cover 6-2, and the lower end of the cover 6-2 is engaged with the limiting protrusion 6-1-2 of the ball 6-1 away from the handle 7. The cover 6-2 is engaged and fixed with the limiting protrusion 6-1-2, so that the ball 6-1 is closed and will not open when the loading ball 6 rotates.

[0036] 2. Install the bearing assembly containing Chinese medicinal materials on the connecting rod 3, specifically install the handle 7 and the plug 4 of the connecting rod 3, insert the plug 4 into the mounting hole 7-1 of the handle 7, the plug 4 and the mounting hole 7-1 of the handle 7 are connected and matched, the plug 4 and the handle 7 are relatively fixed, and the bearing assembly will not rotate around the plug 4 when rotating. At the same time, the ball screw 5 matches the arc groove to achieve the fixation of the plug 4 and the handle 7.

[0037] 3. Start the motor to drive the rotating shaft 2 to rotate, turn on the heating component to start heating the drying cylinder 1. The heating cylinder is fixed to the rotating shaft 2 by a bearing, so the heating cylinder does not rotate with the rotating shaft 2. Each bearing component is fixed to the rotating shaft 2 by a connecting rod 3, so each bearing component rotates with the rotating shaft 2. When the bearing component rotates around the rotating shaft 2, the Chinese medicinal materials in the loading ball 6 will roll to a certain extent, so that the Chinese medicinal materials in the loading ball 6 can change the heating position, making the heating more uniform; while the Chinese medicinal materials roll in the loading ball 6, the medicinal material debris generated by the rolling and stirring will be screened out through the mesh of the loading ball 6, achieving the effect of screening while heating. In addition, since the loading ball 6 rotates with the rotating shaft 2 to achieve the rolling and stirring of the internal Chinese medicinal materials, the Chinese medicinal materials are not directly stirred, which avoids the direct contact of the stirring paddle and reduces the breakage rate of the Chinese medicinal materials during the drying process.

[0038] 4. Control the heating temperature and time of each drying cylinder 1 through the Internet of Things.

[0039] 5. After the Chinese medicinal materials have achieved the desired drying effect, turn off the heating component and the motor, stop heating the heating component, stop rotating the shaft 2, and manually remove the bearing component in the drying cylinder 1 by wearing gloves. Specifically, first pull the handle 7 along the axial direction of the shaft 2 with force, the ball screw 5 can be separated from the arc groove, and the plug 4 can be pulled out from the mounting hole 7-1, and the bearing component can be taken out of the drying cylinder 1.

[0040] 6. The bearing assembly taken out from the drying cylinder 1 is hung on the bearing hook 10 of the transfer cart 8, and the transfer cart 8 is pushed to transfer the dried Chinese medicinal materials to the next process. Specifically, the mounting hole 7-1 of the handle 7 is first put on the inclined section 10-2 of the bearing hook 10, and then the inclined section 10-2 moves to the extension section 10-1. The extension section 10-1 is connected and matched with the mounting hole 7-1 of the handle 7, so the bearing assembly is relatively fixed to the extension section 10-1, and the bearing assembly will not rotate around the extension section 10-1. Figure 8 As shown, two bearing columns 9 are provided on the transfer trolley 8, and the loading balls 6 of the bearing assembly can be placed in two opposite directions respectively to prevent the loading balls 6 on the two bearing columns 9 from interfering with each other due to insufficient space.

[0041] The intelligent drying system of Chinese herbal medicine slices based on the Internet of Things control of the present invention, the Chinese herbal medicine in the loading ball 6 will roll to a certain extent with the rotation of the rotating shaft 2, so that the Chinese herbal medicine in the loading ball 6 can change the heating position, so that the heating is more uniform; while the Chinese herbal medicine rolls in the loading ball 6, the herbal medicine debris generated by the rolling and stirring will be screened out through the mesh of the loading ball 6, which has the effect of screening while heating. The loading ball 6 is a mesh ball, and relative to the structure such as a baking tray, all directions of the ball can be heated, and the mesh hollow heating effect is better. In addition, since the loading ball 6 is used to rotate with the rotating shaft 2 to realize the rolling and stirring of the internal Chinese herbal medicine, the Chinese herbal medicine is not directly stirred, which avoids the direct contact of the stirring paddle and reduces the breakage rate in the drying process of the Chinese herbal medicine. In the whole process of taking medicine, drying, screening and transporting, the Chinese herbal medicine is in the same loading ball 6 and does not need to be taken out midway, so that the drying process is systematized, the operation process is reduced, and the breakage rate due to taking and placing midway is avoided.

[0042] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
