Description

Technical Field

[0001] This utility model relates to the field of silo technology, specifically a novel silo device for mineral materials. Background Technology

[0002] With economic development, more and more industries are using silos in their production processes. Silos are material storage devices widely used in manufacturing, construction, agriculture, chemicals, and many other fields. In the pelletizing industry, almost every production line uses silos. Silos solve the problems of material storage, transfer, and supply-demand balance. However, because they store mineral powder, poor material flowability, uneven particle size distribution, moisture absorption, and agglomeration can lead to material suspension inside the silo. Suspension can cause interruptions in material supply and production, and unstable unloading can affect subsequent processes and output. The existing technology for a new type of silo device for mineral materials has the following drawbacks: In order to forcibly solve the problem of suspension, operators may continuously start the unloading valve, vibrator, and other equipment, causing motor overload. This can burn out the motor coil or damage core components such as gears and bearings, leading to overload and damage to the unloading equipment. In addition, most silos require dedicated personnel to guard them to prevent them from being empty or bursting, and they do not have a structure that allows for quick disassembly and assembly, making efficient maintenance difficult. In view of the above problems, this case was developed after in-depth research. Utility Model Content

[0004] This utility model is implemented as follows: a novel silo device for mineral materials includes: a silo body; a control panel installed on the outer wall of one side of the silo body; 3D cameras installed on the inner walls of both sides above the silo body; a mobile trolley installed above the silo body, with a first servo motor installed inside the mobile trolley; the output end of the first servo motor connected to a turntable via a drive shaft; a mounting box connected to one side of the turntable; a mounting shaft movably mounted on the inner wall of the mounting box via bearings; a fixing sleeve installed on the outer wall of the mounting shaft; an electric telescopic rod installed on the outer wall below the fixing sleeve; a shovel plate connected to the lower part of the electric telescopic rod; a mounting groove provided at the top of the shovel plate; and a mounting block connected to the bottom of the electric telescopic rod that mates with the mounting groove; a shifting mechanism installed on the inner wall of the mobile trolley, which enables the mobile trolley to move automatically; and a disassembly and assembly structure installed on the inner walls of both sides of the mounting block, which facilitates quick disassembly and replacement of the shovel plate.

[0005] Preferably, the shifting mechanism includes: a second servo motor installed on the inner wall of the mobile trolley, the output end of the second servo motor being connected to a rotating gear via a drive shaft, a rack being installed at the top of the hopper body below the rotating gear, the rack and the rotating gear forming a meshing transmission structure, and the rack having a circular top view.

[0006] Preferably, the limiting wheels are connected to both ends of the lower side of the mobile trolley, and the top of the hopper body is provided with a limiting groove that cooperates with the limiting wheels.

[0007] Preferably, a third servo motor is installed on the inner wall of the mounting box, and the output end of the third servo motor is equipped with a drive gear via a drive shaft.

[0011] Compared with related technologies, the novel silo device for mineral materials provided by this utility model has the following beneficial effects: 1. By utilizing the real-time monitoring system of a 3D camera and the collaborative positioning of the displacement mechanism, combined with the turntable, mounting shaft, electric telescopic rod, and shovel plate of the multi-degree-of-freedom robotic arm structure, the automatic identification of the suspended material position and the precise docking of the cleaning device are achieved. This allows the shovel plate to automatically adjust its working position and angle according to the spatial distribution characteristics of the suspended material, which not only significantly improves the success rate of suspended material cleaning, but also avoids repeated impact damage to the silo body caused by traditional air cannons, vibrators, and other equipment, thus extending the service life of the silo.

[0012] 2. The modular quick-assembly structure, including locking rod, locking hole, pressure rod and groove, enables tool-free quick replacement of the scraper plate, which greatly reduces maintenance time and labor costs.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] Example 1 A preferred embodiment of the novel silo device for mineral materials provided by this utility model is, for example... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: A novel silo device for mineral materials includes: a silo body 3; a control panel 2 installed on the outer wall of one side of the silo body 3; 3D cameras 4 installed on the inner walls of both sides above the silo body 3; a mobile trolley 6 installed above the silo body 3; a first servo motor 10 installed inside the mobile trolley 6; the output end of the first servo motor 10 connected to a turntable 7 via a drive shaft; a mounting box 9 connected to one side of the turntable 7; and a mounting shaft 8 movably mounted on the inner wall of the mounting box 9 via bearings. A fixing sleeve 15 is installed, and an electric telescopic rod 5 is installed on the outer wall below the fixing sleeve 15. A scraper plate 1 is connected to the lower part of the electric telescopic rod 5. The top of the scraper plate 1 is provided with an installation groove 17. The bottom of the electric telescopic rod 5 is connected to an installation block 16 that cooperates with the installation groove 17. A shifting mechanism 11 is installed on the inner wall of the moving trolley 6. The shifting mechanism 11 is used to make the moving trolley 6 move automatically. A disassembly and assembly structure 18 is installed on the inner walls on both sides of the installation block 16. The disassembly and assembly structure 18 facilitates the quick disassembly and replacement of the scraper plate 1.

[0018] It should be noted that the existing technology of a new type of silo device for mineral materials has the following drawbacks: In order to forcibly solve the problem of suspended material, operators may continuously start the unloading valve, vibrator and other equipment, which will cause the motor to overload. At best, it will burn out the motor coil, and at worst, it will damage the core components such as gears and bearings, resulting in overload damage to the unloading equipment. In addition, most silos also require dedicated personnel to guard them to prevent the silos from being empty or bursting, and they do not have a structure that is easy to disassemble and assemble quickly, which makes it inconvenient to maintain them efficiently.

[0019] In this embodiment, 3D cameras 4 installed on the inner walls of both sides of the silo body 3 monitor the material status in the silo in real time and construct a three-dimensional material level model. When suspended material is detected, the control system accurately locates the position coordinates of the suspended material through the control panel 2. The second servo motor 1101 of the shifting mechanism 11 drives the rotating gear 1102 to move along the rack 1103, driving the moving trolley 6 to reach directly above the suspended material area. The cooperation between the limiting wheel and the limiting groove ensures the stability during the movement. The first servo motor 10 drives the turntable 7 to rotate, driving the mounting box 9 and the robotic arm structure to rotate to the position of the suspended material. The third servo motor 13 drives the mounting shaft 8 and the fixed sleeve 15 to rotate through the meshing transmission of the driving gear 12 and the driven gear 14, adjusting the cutting angle of the electric telescopic rod 5 and the shovel plate 1. The electric telescopic rod 5 extends and retracts multiple times according to the set program, driving the shovel plate 1 to crush and clean the suspended material, pushing the material to the discharge port. The above process is repeated until the 3D camera 4 confirms that the suspended material has been completely cleared, and the system resumes the monitoring state.

[0020] In a further preferred embodiment of the present invention, the shifting mechanism 11 includes: a second servo motor 1101 installed on the inner wall of the moving trolley 6, the output end of the second servo motor 1101 being connected to a rotating gear 1102 via a drive shaft, a rack 1103 being installed at the top of the hopper body 3 below the rotating gear 1102, and a meshing transmission structure being formed between the rack 1103 and the rotating gear 1102, the rack 1103 being circular in top view.

[0021] In this embodiment, the shifting mechanism 11 drives the rotating gear 1102 to move along the rack 1103 via the second servo motor 1101, thereby enabling the mobile trolley 6 to be precisely positioned and moved on the annular track at the top of the hopper body 3. The rack 1103 is arranged in a circle, allowing the mobile trolley 6 to cover the hopper body 3 in all directions. After the 3D camera 4 identifies the position of the suspended material, the mobile trolley 6 can quickly reach the corresponding area for cleaning. This structure has the advantages of smooth transmission, accurate positioning, and strong load-bearing capacity, and is suitable for long-term continuous operation in industrial environments.

[0022] In a further preferred embodiment of this utility model, the limiting wheels are connected to both ends of the lower side of the mobile trolley 6, and the top of the hopper body 3 is provided with a limiting groove that cooperates with the limiting wheels.

[0023] In this embodiment, the matching structure of the limiting wheel and the limiting groove provides a stable radial constraint for the moving trolley 6. When the shifting mechanism 11 drives the moving trolley 6 to make a circular motion along the rack 1103, the limiting structure can effectively prevent the moving trolley 6 from deviating or overturning during operation, ensuring the accuracy of the movement trajectory and the smoothness of the operation. This structure enhances the operational reliability of the equipment under long-term heavy load conditions.

[0024] In a further preferred embodiment of the present invention, a third servo motor 13 is installed on the inner wall of the mounting box 9, and a drive gear 12 is installed on the output end of the third servo motor 13 via a drive shaft. A driven gear 14 is installed on the outer wall of one end of the mounting shaft 8, and a meshing transmission structure is formed between the driven gear 14 and the drive gear 12.

[0025] In this embodiment, the third servo motor 13 drives the mounting shaft 8 and its connected fixed sleeve 15 and electric telescopic rod 5 to make precise angle adjustments through the meshing transmission of the driving gear 12 and the driven gear 14. This gear transmission structure has the characteristics of high transmission efficiency, accurate positioning and strong load-bearing capacity, which can enable the shovel plate 1 to swing at multiple angles in the horizontal plane, thereby performing precise cleaning operations on suspended materials at different positions in the hopper body 3.

[0026] In a further preferred embodiment of this utility model, a slide groove is provided at the top of the mobile trolley 6. The slide groove is circular in top view. Both sides of the bottom end of the turntable 7 are movably connected to the slide groove by sliders.

[0027] In this embodiment, the cooperative structure of the circular groove and the slider provides stable rotational support for the turntable 7. When the first servo motor 10 drives the turntable 7 to rotate, the sliding pair structure can effectively bear the radial and axial loads generated by the turntable 7 and its components such as the mounting box 9 and the robotic arm, ensuring smooth and stable rotational motion.

[0028] Example 2 Based on Embodiment 1, a preferred embodiment of the novel silo device for mineral materials provided by this utility model is as follows: Figure 1 and Figure 5 As shown: The disassembly and assembly structure 18 includes: spring dampers 1801 installed on the inner walls of both sides of the mounting block 16, a first return spring 1802 installed on the outer wall of the extension end of the spring damper 1801, a locking rod 1803 connected to the extension end of the spring damper 1801, and a locking hole 1804 that cooperates with the locking rod 1803 on both sides of the inner wall of the mounting groove 17.

[0029] In this embodiment, the disassembly and assembly structure 18, through the cooperation of the spring damper 1801 and the locking rod 1803, realizes the rapid locking and releasing of the scraper plate 1. When the mounting block 16 is inserted into the mounting slot 17, the locking rod 1803 automatically engages with the locking hole 1804 under the combined action of the spring damper 1801 and the first return spring 1802, thus completing reliable locking. During disassembly, it is only necessary to overcome the spring force to remove the locking rod 1803 from the locking hole 1804 to achieve rapid separation of the scraper plate 1. This structure enables convenient replacement of the scraper plate 1 after wear, reducing equipment maintenance downtime.

[0030] In a further preferred embodiment of the present invention, a second return spring 1805 is installed on the inner wall of a groove 1807 connected to one end of a lock hole 1804, and a pressure rod 1806 is installed on the inner side of each second return spring 1805, with one end of each pressure rod 1806 extending into the interior of the lock hole 1804.

[0031] In this embodiment, the groove 1807 not only provides installation space for the second return spring 1805 and the pressure rod 1806, but also features a structure that facilitates manual operation. When it is necessary to disassemble the scraper plate 1, the operator can directly insert their fingers into the groove 1807 and press the pressure rod 1806 inward to disengage the locking rod 1803 from the locking hole 1804 area, thereby releasing the restriction on the locking rod 1803. This design enables a quick unlocking operation that can be completed without special tools, greatly improving the convenience of replacing the scraper plate 1. At the same time, the opening size of the groove 1807 has been optimized to effectively prevent foreign objects from entering while ensuring operational convenience, thus ensuring the long-term reliable operation of the mechanism.

[0032] In summary, the shifting mechanism 11 enables precise positioning of the mobile trolley 6 along the circumference of the hopper body 3. The circumferential rotation of the robotic arm is achieved through the cooperation of the turntable 7 and the chute. The angle adjustment of the shovel plate 1 is accomplished by the active gear 12, the driven gear 14, and the third servo motor 13. The vertical lifting of the shovel plate 1 is achieved by the electric telescopic rod 5, which crushes and cleans the suspended material. The shovel plate 1 can be easily replaced through the structure 18 with quick disassembly and assembly function. The entire mechanism works in concert, enabling the shovel plate 1 to accurately reach any suspended material position in the hopper body 3 under the guidance of the 3D camera 4. It achieves efficient cleaning operations through multi-degree-of-freedom motion. This integrated mechanical structure not only significantly improves the success rate and efficiency of suspended material cleaning, but also reduces maintenance costs through modular design, providing reliable technical support for the automated operation of the hopper body 3.
