[0016] 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.
[0017] Please see Figure 1 - Figure 6 This utility model provides an embodiment of a planetary mixer with an observation and illumination structure, comprising a device body 1 and a storage tank body 4 detachably mounted on the device body 1. The invention is characterized by further comprising a lifting drive assembly mounted on the device body 1, a sliding bracket 21 slidably connected to the device body 1, a main mounting shell 22 fixedly connected to the sliding bracket 21, a transmission assembly and an adjustment assembly mounted on the main mounting shell 22, a planetary gear assembly and a sleeve assembly mounted on the main mounting shell 22, an observation window glass plate 211 mounted on the sleeve assembly, a threaded connection buckle 212 fixedly mounted on the observation window glass plate 211, a stirring execution assembly and a scraper assembly mounted on the planetary gear assembly, the sleeve assembly connected to the output end of the adjustment assembly, the planetary gear assembly mounted and connected to the output end of the transmission assembly, and the sliding bracket 21 connected to the output end of the lifting drive assembly. The storage tank body 4 is used to store the material to be stirred. The threaded connection buckle 212 is used to install a detection device for auxiliary observation. During stirring, the sliding bracket 21 and its connected components are driven to descend by the lifting drive component. The opening of the storage tank body 4 is closed by the sleeve component. The planetary gear component is driven by the transmission component. The stirring execution component and the scraper component are driven to rotate by the planetary gear component. After the material to be mixed is stored inside the storage tank body 4, the lifting drive assembly is first activated, which drives the sliding bracket 21 and the main mounting shell 22 to move downward, so that the sleeve assembly moves closer to the storage tank body 4. After the storage tank body 4 is sealed, the transmission assembly is activated. When the transmission assembly is working, it drives the planetary gear assembly to work, which drives the mixing execution assembly to mix the material inside the storage tank body 4. During mixing, the scraper assembly scrapes off the material adhering to one side of the mixing execution assembly. During mixing, the sleeve assembly is rotated by operating the adjustment assembly so that the staff can observe the mixing situation of the contents of the storage tank body 4.
[0018] Please see Figure 1 - Figure 2A further solution based on this embodiment is as follows: The lifting drive assembly includes a first motor 23 fixedly installed on the main body 1 of the device and a threaded rod 24 fixedly connected to the output end of the first motor 23. The sliding bracket 21 is threadedly connected to the threaded rod 24. The first motor 23 is used to drive the threaded rod 24 to rotate. When the threaded rod 24 rotates, it drives the sliding bracket 21 to move along a preset direction. After the first motor 23 is powered on and started, its output end drives the threaded rod 24 to rotate around its own axis. Since the sliding bracket 21 is threadedly connected to the threaded rod 24, the rotational motion of the threaded rod 24 is converted into the linear motion of the sliding bracket 21 along a preset trajectory, thereby driving the components on the sliding bracket 21 to move synchronously. Through the combination of motor drive and threaded transmission, the precise displacement control of the sliding bracket 21 is realized. The movement trajectory in the preset direction can ensure that the sliding bracket 21 is accurately positioned.
[0019] Please see Figure 1 - Figure 3 A further embodiment of this solution is as follows: the adjustment assembly includes a worm gear 25 rotatably connected to the main mounting housing 22, an adjustment knob 26 fixedly connected to the worm gear 25, a worm wheel 27 meshing with the worm gear 25, and a first gear 28 fixedly connected to the worm wheel 27. A sleeve assembly is connected to the first gear 28. The worm wheel 27 is rotatably connected to the main mounting housing 22. The adjustment knob 26 is used to drive the worm gear 25 to rotate. When the worm gear 25 rotates, it drives the first gear 28 to rotate through meshing with the worm wheel 27. Manually rotating the adjustment knob 26 drives the worm gear 25 to rotate. The rod 25 rotates around the connection point on the main mounting housing 22. The worm gear 25 drives the worm wheel 27 to rotate synchronously through tooth meshing. The first gear 28, which is fixed to the worm wheel 27, rotates together with the worm wheel 27, thereby driving the sleeve assembly connected to the first gear 28 to adjust its position. The worm wheel 27 and worm gear 25 transmission has self-locking properties, which can prevent the sleeve assembly from shifting due to external force after adjustment, ensuring operational stability. The manual adjustment is achieved by a knob, which is convenient to operate and can precisely control the speed of the first gear 28. The position of the sleeve assembly can be adjusted according to different observation requirements.
[0020] Please see Figure 1 - Figure 3A further embodiment of this solution is as follows: the sleeve assembly includes a second gear 29 rotatably connected to the main mounting shell 22, a mounting sleeve 210 fixedly connected to the second gear 29, an observation window glass plate 211 fixedly mounted on the mounting sleeve 210, and a threaded connection buckle 212 fixedly mounted on the observation window glass plate 211. The second gear 29 meshes with the first gear 28. When the first gear 28 rotates, it drives the mounting sleeve 210 to rotate through meshing with the second gear 29. When the first gear 28 rotates, it drives the second gear 29 to rotate around the connection point on the main mounting shell 22 through meshing with the second gear 29. The mounting sleeve 210 fixed to the second gear 29 rotates synchronously with the second gear 29. The observation window glass plate 211 and the threaded connection buckle 212 on the mounting sleeve 210 also rotate accordingly. The rotation of the mounting sleeve 210 can adjust the position of the observation window glass plate 211, making it easier to observe the stirring state of the material in the storage tank body 4 from different angles. The threaded connection buckle 212 can be used to install a detection device to further assist personnel in observation.
[0021] Please see Figure 1 - Figure 4 A further embodiment of this solution is as follows: the transmission assembly includes a second motor 213 fixedly mounted on the main mounting housing 22, a second sprocket 215 and a first sprocket 214 rotatably connected to the main mounting housing 22, and a chain 216 meshing between the second sprocket 215 and the first sprocket 214. The first sprocket 214 is fixedly connected to the output end of the second motor 213, and a planetary gear assembly is connected to the second sprocket 215. The second motor 213 drives the first sprocket 214 to rotate, and the first sprocket 214 rotates through the chain. The second motor 213 drives the second sprocket 215 to rotate. After the second motor 213 starts, its output end drives the first sprocket 214 to rotate around the connection point on the main mounting housing 22. The first sprocket 214 forms a transmission relationship with the second sprocket 215 through the chain 216. The chain 216 moves with the first sprocket 214 and drives the second sprocket 215 to rotate synchronously, thereby providing power to the planetary gear assembly connected to the second sprocket 215. The sprocket and chain 216 has high transmission efficiency and strong load-bearing capacity, and can stably transmit the power of the second motor 213.
[0022] Please see Figure 2 - Figure 5A further embodiment of this scheme is as follows: the planetary gear assembly includes a rotating disk 217 and a gear disk 218 rotatably connected to the main mounting housing 22, a third gear 220 meshing with the gear disk 218, and a fourth gear 221 fixedly connected to the second sprocket 215. The fourth gear 221 meshes with the third gear 220. A stirring execution component is connected to the third gear 220. A scraper assembly is mounted on the gear disk 218. When the second sprocket 215 rotates, it drives the fourth gear 221 to rotate. When the fourth gear 221 rotates, it drives the third gear 220 to rotate. When the third gear 220 rotates, it drives the gear disk 218 to rotate; the second sprocket 215 rotates, driving the fourth gear 221 to rotate synchronously. The fourth gear 221 drives the third gear 220 to rotate around its own axis through tooth meshing. The third gear 220 meshes with the gear disk 218, thereby driving the gear disk 218 to rotate. At the same time, the rotating disk 217 moves with the gear disk 218 to adjust its position. The stirring execution component rotates with the third gear 220, and the scraper assembly rotates with the gear disk 218. Through multi-stage gear meshing, a compound motion is achieved, causing the stirring execution component and the scraper assembly to rotate.
[0023] Please see Figure 4 - Figure 5 A further solution based on this embodiment is as follows: The stirring execution component includes a first rotating shaft 219 fixedly mounted on the third gear 220 and a stirring rod 222 fixedly mounted on the first rotating shaft 219. The first rotating shaft 219 is rotatably connected to the rotating disk 217. When the third gear 220 rotates, it drives the first rotating shaft 219 to rotate. When the third gear 220 rotates, its power is transmitted to the fixedly connected first rotating shaft 219. The first rotating shaft 219 rotates synchronously around the connection point on the rotating disk 217. The stirring rod 222 mounted on the first rotating shaft 219 rotates together with the first rotating shaft 219 to stir the material in the storage tank body 4. The stirring rods 222 on both sides rotate to penetrate deep into the material for stirring. The rotational connection between the first rotating shaft 219 and the rotating disk 217 can limit the shaking of the rotating shaft and ensure the stability of the movement trajectory of the stirring rod 222.
[0024] Please see Figure 4 - Figure 6A further embodiment of this solution is as follows: the scraper assembly includes a fixed shaft 223 fixedly mounted on the gear disk 218, a fixed housing 224 fixedly connected to the fixed shaft 223, a flip scraper 225 rotatably connected to the fixed housing 224, a fixed buckle 226 fixedly connected to the flip scraper 225, and a thrust spring 227 fixedly connected between the fixed buckle 226 and the fixed housing 224; when the gear disk 218 rotates, it drives the fixed shaft 223 to move synchronously, and the fixed shaft 223 drives the fixed housing 224 and the flip scraper 225 to move. When the stirring rod 222 rotates, it can push the flip scraper 225 to clean the material attached to the side of the stirring rod 222, and the flip scraper 225 can be reset under the elastic force of the thrust spring 227.
[0025] Working principle: After the material to be stirred is stored inside the storage tank body 4, the first motor 23 of the lifting drive component is started first. When the first motor 23 is working, it drives the threaded rod 24 at its output end to rotate. During the rotation of the threaded rod 24, it drives the sliding bracket 21 that cooperates with it to move along the preset direction. When the sliding bracket 21 moves, it drives the main mounting shell 22 connected to it and the components on the main mounting shell 22 to move together until the sleeve assembly approaches the storage tank body 4 and closes the opening of the storage tank body 4, and the stirring work can begin. Then, the second motor 213 of the transmission assembly is started. When the second motor 213 is working, it drives the first sprocket 214 at its output end to rotate. When the first sprocket 214 rotates, it drives the second sprocket 215 through the chain 216. When the second sprocket 215 rotates, it drives the fourth gear 221 of the planetary gear assembly connected to it to rotate. During the rotation of the fourth gear 221, it cooperates with the third gear 220 to drive the third gear 220 to rotate. When the third gear 220 rotates, it cooperates with the gear disk 218 to drive the gear disk 218 to rotate. When the third gear 220 of the planetary gear assembly rotates, it drives the first rotating shaft 219 of the stirring execution assembly connected to it to rotate. During the rotation of the first rotating shaft 219, it drives the stirring rod 222 on itself to rotate. When the stirring rod 222 rotates, it stirs the material in the storage tank body 4. When the gear disk 218 of the planetary gear assembly rotates, it drives the fixed shaft 223 of the scraper assembly connected to it to rotate. When the fixed shaft 223 rotates, it drives the fixed housing 224 and the tilting scraper 225 to move. During the rotation of the stirring rod 222, it pushes the tilting scraper 225. When the tilting scraper 225 is pushed, it cleans the material attached to the side of the stirring rod 222. After cleaning, the thrust spring 227 between the fixed buckle 226 and the fixed housing 224 will drive the tilting scraper 225 to return to its original position so that the material on the side of the stirring rod 222 can be cleaned continuously in the future, ensuring that the entire stirring process proceeds in an orderly manner. During the stirring process, if it is necessary to observe the stirring of the material inside the storage tank body 4, the adjustment knob 26 of the adjustment component can be operated. When the adjustment knob 26 is turned, it drives the worm gear 25 to rotate. During the rotation of the worm gear 25, it cooperates with the worm wheel 27 to drive the first gear 28 on the worm wheel 27 to rotate. When the first gear 28 rotates, it cooperates with the second gear 29 of the sleeve assembly to drive the second gear 29 to rotate. When the second gear 29 rotates, it drives the connected mounting sleeve 210 to rotate, so that the staff can observe the stirring of the material inside the storage tank body 4 from different angles. The threaded connection buckle 212 is used to install an external lighting unit to assist the staff in observation.
